The detailed connection means are well-known technologies in this field. The following mainly introduces the working principles and processes, and no longer explains the electrical control.

[0021] Embodiment 1:

[0022] Depend on Figure 1 , 3 As shown in Figure 4, a fully automatic automobile maintenance manipulator comprises an automatic manipulator arm 1, a U-shaped plate 2 is mounted on the automatic manipulator arm 1, an L-shaped plate 3 is mounted on the U-shaped plate 2, a servo motor 5 is mounted on the L-shaped plate 3, bearings 6 are respectively mounted in the circular holes pre-opened at the ear positions on both sides of the U-shaped plate 2, a double-headed threaded rod 7 is connected to the output shaft of the servo motor 5, both sides of the double-headed threaded rod 7 are respectively mounted in the bearings 6, limiting grooves 9 are respectively opened on both sides of the U-shaped plate 2, clamping plates 8 are respectively slidably mounted in the limiting grooves 9, and both sides of the double-headed threaded rod 7 are respectively sleeved in the threaded openings pre-opened on the clamping plate 8;

[0023] A tightening structure 4 is installed on one of the clamping plates 8. The tightening structure 4 includes an electric push rod 401, an arc plate 402, an arc groove 403, a baffle plate 404, a screw 405 and a nut 406. The electric push rod 401 is installed in a pre-opened installation groove on the clamping plate 8, the arc plate 402 is installed on the output end of the electric push rod 401, the arc groove 403 is opened on the arc plate 402, the screw 405 passes through a pre-opened hole on the baffle plate 404, the screw passes through the arc groove 403, and the nut 406 is sleeved on the screw 405;

[0024] In the specific implementation process, it is worth pointing out that the U-shaped plate 2 can be installed on the automatic robot arm 1 by welding or bolting, the servo motor 5 and the electric push rod 401 are automatically controlled by the control module of the automatic robot arm 1 and powered by the power supply of the automatic robot arm 1, the bearing 6 can position the double-headed threaded rod 7 in the U-shaped plate 2 and can rotate stably, the pre-opened threaded opening on the clamping plate 8 matches the thread machined on the surface of the double-headed threaded rod 7, the limiting groove 9 is a rectangular groove, the width of which is consistent with the width of the protruding position above the clamping plate 8, which has a limiting effect on the movement of the clamping plate 8;

[0025] The baffle 404 is in front of the arc plate 402, the outer diameter of the screw 405 is smaller than the inner diameter width of the arc groove 403, and the contact position between the screw 405, the arc groove 403 and the hole on the baffle 404 is not processed with threads. The screw 405 is used as a pin for the rotation of the baffle 404. When the baffle 404 needs to be fixed in the rotation adjustment position, the nut 406 can be screwed on the screw 405 to fix the position of the baffle 404;

[0026] Specifically, the baffle 404 drives the screw 405 to slide and adjust the position along the arc groove 403 on the arc plate 402, and makes the baffle 404 in a horizontal state. At this time, the nut 406 is screwed to fix the position of the baffle 404 (the preparatory work done by the manual station before the robot works does not affect the fully automatic operation of the robot), and the automatic robot arm 1 drives the U-shaped plate 2 to approach the auto parts and controls the servo motor 5 to work. The output shaft of the servo motor 5 drives the double-headed threaded rod 7 to rotate on the U-shaped plate 2 through the bearing 6, so that the clamping plate 8 moves along the limiting groove 9 to clamp the auto parts, and at the same time controls the electric push rod 401 to work. The output end of the electric push rod 401 drives the baffle 404 to approach the clamped auto parts through the arc plate 402, and presses against the auto parts to prevent the clamped moving auto parts from slipping.

[0029] In the specific implementation process, it is worth pointing out that the U-shaped plate 2 is installed on the automatic mechanical arm 1 by bolting, so that the U-shaped plate 2 can be disassembled for easy maintenance;

[0030] Specifically, the second thread groove 14 on the U-shaped plate 2 is screwed onto the second bolt 13 on the automatic robot arm 1, so that the U-shaped plate 2 is installed on the automatic robot arm 1, and vice versa, the accessories on the U-shaped plate 2 can be disassembled for maintenance;

[0031] On the basis of the above-mentioned embodiment 1, an anti-slip structure is installed on the clamping plate 8, and the anti-slip structure is arranged corresponding to the clamping plate 8. The anti-slip structure includes a transverse plate 10, a first thread groove 11 and a first bolt 12. The first thread groove 11 is opened on the clamping plate 8, and the first bolt 12 is installed on the transverse plate 10. The first bolt 12 is sleeved in the first thread groove 11;

[0033] Specifically, the first bolt 12 on the horizontal plate 10 is screwed into the first thread groove 11 on the clamping plate 8, so that the horizontal plate 10 is installed on the clamping plate 8. The arrangement of the horizontal plate 10 prevents the clamping plate 8 from being separated from the limiting groove 9.

[0034] On the basis of the above-mentioned embodiment 1, a round block 16 is installed on the side wall of the nut 406, and a hexagonal hole 17 is opened on the round block 16;

[0035] In the specific implementation process, it is worth pointing out that the round block 16 can be installed on the nut 406 by fixed connection or bolting, and the round block 16 can be rotated and the nut 406 can be rotated at the same time through the hexagonal hole 17;

[0036] Specifically, an external hexagonal wrench is inserted into the hexagonal hole 17 on the round block 16, and the round block 16 is rotated while the nut 406 is rotated to be screwed on the screw 405;

[0037] Furthermore, a threaded hole 18 is formed on the nut 406, and an external thread is processed on the outside of the round block 16, and the external thread on the round block 16 is sleeved in the threaded hole 18;

[0038] In the specific implementation process, it is worth pointing out that the round block 16 is installed on the nut 406 by bolting, which can be disassembled and installed, and is easy to replace;

[0039] Specifically, the external thread on the round block 16 is screwed into the threaded hole 18 on the nut 406, so that the round block 16 is installed on the nut 406, and when the hexagonal hole 17 is worn, the round block 16 can be removed and replaced without replacing the nut 406, which saves money;

[0040] On the basis of the above-mentioned embodiment 1, an elastic band 15 is installed between the two clamping plates 8, and the elastic band 15 is used to block one side of the clamping plates 8;

[0041] In the specific implementation process, it is worth pointing out that the elastic band 15 is usually made of natural latex or synthetic rubber, such as TPE rubber, and sometimes fiber materials and steel wires are added to improve the toughness of the elastic band 15. The elastic band 15 is located at the rear side between the clamping plates 8 and does not affect the clamping of the auto parts by the clamping plates 8. At the same time, the elastic band 15 can follow the expansion and contraction of the clamping plates 8 to hold the auto parts.

[0042] Specifically, when the clamping plate 8 clamps the automobile accessory and moves, the elastic band 15 follows the expansion and contraction movement according to its own elasticity, and the elastic band 15 plays the role of limiting the rear side of the clamped automobile accessory.
