1. When working, you must choose the right tool, use it correctly, and not replace it. Tools should be kept intact, firmly applied and checked regularly. Found that there is a defective replacement.
2. Various sharp-edged tools (such as planers, drills, chisels, axes, and various types of knives, etc.) are not allowed to be inserted into the belt or placed in the pockets of the clothes; the front edge must not face outward when transported or stored. To avoid hurting people.
3. The use of hand hammers and hammers is not allowed to wear gloves. Stand in opposite directions when standing in double operation.
4. When you pass the tool, you are not allowed to throw it. Place larger tools and materials on flat surfaces to avoid injury.
5. The installation of tools and instruments should be firm and tight and prevent the danger of falling off or breaking during use.
6. Using a hacksaw, the saw blade should be securely mounted and moderately tight, and the force should be uniform when used. Do not swing it to the left or right so as not to break the steel saw blade.
7. When using wrenches or pliers, inspections should be performed. Damaged or unmovable moving parts should not be used. Do not use too much force, do not allow mutual substitution, and do not allow long handles to be removed.
8. The use of pulleys, tighteners, should be regularly filled with oil to keep active parts free. It is forbidden to use small or large children. The tightener key (handle) must not be fitted with a sleeve or extension.
Second, ladder, high stool
(a) When using ladders, the following must be noted:
1. Always check that the ladder is intact; any ladder that has been broken, loosened, broken, slipped off, and rotted must not be used.
2. Up and down ladders must not carry bulky tools and materials.
3. There must be no two people working on the ladder at the same time.
Third, seat belt and rod tools
(1) The following items must be observed when using seat belts:
1. Before use, it must be strictly inspected to ensure it is reliable and reliable. If there is a crease, the spring buckle is not flexible, or can not be fastened, the belt eye has a crack, the belt wear on the belt and the broken end of more than 1/10 and there is corruption, are prohibited.
2. Should be separated from the acid, sharp edge tools and storage, etc., and should not be placed on the stove, radiators and other places too hot and humid, so as not to damage.
3. When using, do not twist the belt. All buckles on the belt should be buckled properly. The belt head should pass through the small circle of the belt. The ropes and safety ropes of the seat belts shall not be buckled and the objects shall not be hoisted so as not to damage the ropes.
4. Every time the belt is used or stored for a certain period of time, a reliability test should be performed. The test method is that the weight of 200 kilograms can be passed through the seat belt, suspended and hung. There are no scars, breaks, and the fastening must be secure before use.
(b) Do not use ordinary ropes or various insulated skins instead of seat belts.
(C) Notes on the use of foot buckles:
1. Always check that it is in good condition. Do not make it slippery and sharp. The strap must be strong and durable. The buckle plate and hook must be riveted.
2. The size of the buckle should be suitable for the thickness of the pole, and do not expand the socket by the foot buckle because it is not suitable for use.
3. The hoses and pads on the concrete stem should be kept intact. When the cracks are exposed on the plastic line, they should be replaced. Others require the same general buckle.
4. The hooks, ropes, and plates of the footboard must be kept in good condition before use.
5. The test method for the foot buckle is:
(1) The foot buckle is stuck on the pole about 30 centimeters from the ground, one foot is suspended, and one foot is slammed with the maximum force.
(2) 200 kg of suspended hangings should be used in the center of the foot plate. Only if there is no sign of damage and deformation, can it be used.
Four, pulleys and ropes
(1) All kinds of pulleys should always check the oil injection and keep it well. If there are signs of damage or missing parts, they should not be used.
(2) Never use a pulley to pull up or put down any heavy objects.
Fifth, torch
(1) Do not use torches that leak oil or leak air. Refueling must not be excessive, and air pressure must not be too high. Do not heat the torch on the stove to avoid danger.
(2) It is forbidden to ignite and repair the torch near any flammable material. When using torches at high altitudes, you must use ropes to hang or hang them.
(3) The burning torch cannot be reversed.
(4) The lit torch cannot be refueled, and the flame must be extinguished when it is refueled. After a little cold, add fuel.
(5) The use of torches must use specified oils and should not be used on their own behalf to avoid danger.
(6) Do not use torches to boil water or cook rice.
(7) After the blowtorch is used up, deflate the gas in a timely manner and switch the throttle once to avoid the blown light blocking.
Their rollers and the outer wheels are arranged in a right angle intersecting intersecting. They can bear the load from all directions at the same time (such as axial, thrust or momentum hormones, etc.). Because of the linear contact between the roller and the track surface, the possibility of the axis to bear the load and the elastic deformation is very small. This type of bearing is widely used in industrial robots, working machines and medical facilities. It needs high rigidity, high speed and high speed to ensure precise occasions.
In cross roller bearings, cylindrical rollers are perpendicular to each other through spacer retainers on the top, so 1 cross roller bearings can bear all loads of radial load, axial load and torque load. Ring size is the minimum limit of miniaturization, especially very thin type is small size close to the limit, and has high rigidity, so the most suitable for use in industrial robot joint or rotating parts, machining center machine rotary table, hand rotating parts, precision rotary table, medical machine, metering device, IC manufacturing equipment etc.
1. Excellent rotation accuracy
The inner structure of the Cross Roller Bearing is arranged in 90 degrees perpendicular to each other by the roller.
The roller is equipped with a spacer or isolation block between the rollers to prevent the rolling of the rollers from being examined each other. In addition, the phenomenon of roller contact or locking will not occur. At the same time, because the inner and outer ring is a segmented structure, the clearance can be adjusted, even if the preload is applied, high accuracy rotation motion can also be achieved.
2. Simplification of operation and installation
The outer ring or inner ring, which is divided into 2 parts, is fixed together after loading the roller and the holder, so the operation is very simple.
3. Bear large axial and radial load
The roller is arranged vertically through the spacer retainer on a 90 degree V groove rolling surface.
4. Greatly save the installation space
The size of the inner and outer ring cross roller bearing is miniature minimal, especially ultra-thin structure is small size close to the limit, and has high rigidity, so the most suitable for industrial robot joints or rotating parts, machining center of the rotary table, the robot rotating parts, precision rotary table, medical instrument IC, measuring equipment, manufacturing device widely used.
5. high speed ability
6. reducing shaft length and machining cost, thermal expansion leads to a limited change in geometric size.
7. the nylon separator is used, the moment of inertia is low, the starting torque is low, and the angle degree is easy to control.
8. optimization of pretightening force, large rigidity, high precision of guiding roller
9. carbon steel provides excellent impact resistance and surface abrasion resistance
10. simple but fully lubricated
