[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] Example 1

[0021] The utility model provides a high-precision hardware parts processing robot arm, such as Figures 1 to 3The U-shaped bracket 4 is fixedly mounted on the back of the robot arm 3, and a first fixing block 5 is fixedly mounted inside the U-shaped bracket 4 on the back of the robot arm 3. A screw 7 is connected to the inside of the U-shaped bracket 4 by a thread. One end of the screw 7 is located inside the U-shaped bracket 4 and is connected to a bearing 8 by interference fit. The end of the bearing 8 away from the screw 7 is fixedly connected to the second fixing block 6. The inner wall of the U-shaped bracket 4 is fixedly connected with two limit baffles 9. The adjacent sides of the two limit baffles 9 are flush with the upper and lower surfaces of the second fixing block 6 respectively. Semicircular notches are provided on the opposite surfaces of the first fixing block 5 and the second fixing block 6. The first fixing block 5 and the second fixing block 6 are of the same size and the two semicircular notches are also of equal size. The electrical wires of the robot arm 3 are placed in an orderly manner through the circular notches, which is convenient for maintenance personnel to inspect the circuits of the robot arm 3 and reduces the difficulty of the maintenance personnel's work.

[0022] like Figure 1 and Figure 4 As shown, the bottom end of the robotic arm 3 is located inside the rotating disk 2 and is fixedly installed with a base 10. An electric push rod 11 is provided at one end of the base 10 away from the robotic arm 3. A push plate 12 is fixedly installed at the output end of the electric push rod 11. The bottom end of the robotic arm 3 is symmetrically installed with fixed brackets 13 on both sides of the base 10. An oil storage tank 14 is fixedly installed between the two fixed brackets 13. The electric push rod 11 is installed to drive the electric push rod 11 to drive the push plate 12 to move downward. The size of the push plate 12 is the same as the inner diameter of the oil storage tank 14. The electric push rod 11 is driven to make the push plate 12 move downward in the oil storage tank 14. The oil pump 12 is moved downward, and the lubricating oil inside the oil tank 14 is squeezed out. The squeezed lubricating oil falls to the connection between the base 1 and the rotating disk 2, so that the friction between the rotating disk 2 and the base 1 is reduced when the rotating disk 2 rotates, thereby extending the service life of the equipment. The oil outlet of the oil tank 14 is provided with a valve. When the electric push rod 11 stops working and no longer drives the push plate 12 inside the oil tank 14 to move downward, the valve is no longer squeezed by the lubricating oil inside the oil tank 14 and is in a closed state. The valve provided at the oil outlet of the oil tank 14 can facilitate the control of the discharge of the lubricating oil inside the oil tank 14.

[0023] Working principle: When using this device, the circuit is integrated. The maintenance personnel place each electric wire inside the semicircular notch opened inside the first fixed block 5, and then rotate the screw 7 to move the screw 7 in the direction close to the robot arm 3. One end of the screw 7 is connected to the inner ring of the bearing 8 through an interference fit. The outer ring of the end of the bearing 8 away from the screw 7 is fixedly connected to the second fixed block 6. Through the limit baffles 9 fixedly installed on both sides of the second fixed block 6, when the screw 7 inside the rotating U-shaped bracket 4 moves, under the action of the limit baffles 9, the screw 7 drives the second fixed block 6 to move in the direction close to the robot arm 3, thereby individually connecting each electric wire of the robot arm 3. It is uniquely placed inside the circular groove formed by the first fixed block 5 and the second fixed block 6, which is convenient for maintenance personnel to inspect and repair the line and reduce the difficulty of the maintenance personnel's work. When the rotating disk 2 at the top of the base 1 rotates, the electric push rod 11 is driven to work to make the push plate 12 at the output end move downward, so that the push plate 12 moves downward inside the oil storage tank 14, and then the lubricating oil inside the oil storage tank 14 is squeezed out. The squeezed lubricating oil falls to the connection between the base 1 and the rotating disk 2, which helps to reduce the friction generated when the rotating disk 2 rotates, thereby avoiding a large amount of heat generated by the friction between the base 1 and the rotating disk 2, and further extending the service life of the equipment.

[0024] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
