Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] Figures 1 to 4 As shown, this utility model provides a technical solution: an automatic locking device for wire clamps, used for locking wire clamp assemblies. The wire clamp assembly includes: a wire clamp support 1 for placing wire harnesses, a main body 2 fixedly connected to the wire clamp support 1, the main body 2 having a groove for placing wire harnesses, a pressing block 3 hinged to one end of the main body 2, the pressing block 3 also having a groove that cooperates with the wire harnesses, and a locking block 5 hinged to the other end of the pressing block 3 via a connecting rod 4.

[0024] A support frame 6 is fixedly connected to the lower surface of the main body 2. A first cylinder 8 is fixedly connected to the support frame 6. A drive plate 9 that cooperates with the clamping block 3 is fixedly connected to the telescopic rod of the first cylinder 8. A slide rail that cooperates with the drive plate 9 is fixedly connected to the support frame 6. The telescopic rod of the first cylinder 8 drives the drive plate 9 to cooperate with the clamping block 3, so that the clamping block 3 rotates around the hinge point and drives the wire harness to perform initial clamping.

[0025] A displacement component is fitted on the lower surface of the support frame 6. The displacement component drives the connecting rod 4 and the locking block 5 to cooperate with the clamping component, thereby driving the locking block 5 and the connecting rod 4 to rotate around the hinge point and driving the wire clamping component to lock.

[0026] The displacement assembly includes a displacement module 7, which is movably equipped with a displacement plate 10. The displacement module 7 mainly drives the displacement plate 10 to move and drives the support frame 6 and the wire clamp to move towards the clamping assembly.

[0027] The displacement plate 10 is equipped with a lifting assembly, which includes a support frame 6 and a wire clamp assembly for lifting. The lifting assembly mainly drives the displacement plate 10 to lift, while the displacement plate 10 drives the wire clamp assembly to lift.

[0028] The lifting assembly includes: a lifting cylinder 11 fixedly mounted on the displacement plate 10; a lifting drive block 12 fixedly connected to the telescopic rod of the lifting cylinder 11; a lifting drive wheel 13 cooperating with the lifting drive block 12 on the lower surface of the support frame 6; an inclined surface cooperating with the lifting drive wheel 13 on the lifting drive block 12; the inclined surface having a low point and a high point; when the low point of the inclined surface contacts the lifting drive wheel 13, the support frame 6 is in the initial position; when the high point of the inclined surface contacts the lifting drive wheel 13, the support frame 6 is in the lifting state.

[0029] The displacement plate 10 is fixedly connected with multiple guide posts 14. The support frame 6 is provided with guide bushings that cooperate with the guide posts 14. A tension spring 15 is connected between the support frame 6 and the displacement plate 10. A spring is sleeved on the guide post 14 between the support frame 6 and the displacement plate 10. The spring gives the support frame 6 an upward force, and the pull ring gives the support frame 6 a downward force. By balancing the two forces, the stability of the support frame 6 in moving up and down is ensured.

[0030] A displacement sensor 16 is provided on both sides of the displacement module. A displacement sensing plate 17 that cooperates with the sensor is fixedly connected to the displacement plate 10. By cooperating with the displacement sensor 16, the distance of the displacement plate 10 can be sensed, thereby improving the displacement accuracy.

[0031] A lifting sensor is fixedly connected to the displacement plate 10, and a lifting sensor plate that cooperates with the lifting sensor is fixedly connected to the support frame 6. The lifting accuracy is improved by the cooperation between the lifting sensor and the lifting sensor plate.

[0032] After the clamping block 3 is initially clamped, the connecting rod 4 and the locking block 5 need to be locked by the clamping assembly. Therefore, the clamping assembly includes: a second cylinder 18, the telescopic rod of the second cylinder 18 is fixedly connected to a moving plate 19, and the end of the moving plate 19 is fixedly connected to a first positioning plate 20 that cooperates with the connecting rod 4 and the locking block 5. The second cylinder 18 is fixed to the processing equipment (not shown in the figure). The processing equipment is also fixedly connected to a guide rail that cooperates with the moving plate 19. The second cylinder 18 drives the first positioning plate 20 to contact the connecting rod 4 and the locking block 5. It drives the locking block 5 and the connecting rod 4 to rotate around the hinge point. In order to reduce the friction during contact, the first positioning plate 20 is provided with rollers 24 that contact the locking block 5 and the connecting rod 4.

[0033] The movable plate 19 is fixedly connected to the third cylinder 21. The telescopic rod of the third cylinder 21 is fixedly connected to the second positioning plate 22 that cooperates with the locking block 5. The movable plate 19 is fixedly connected to the guide rail that cooperates with the second positioning plate 22. The second positioning plate 22 is also provided with rollers 24 that contact the locking block 5 and the connecting rod 4.

[0034] A limiting block 23 is fixedly connected to the lower surface of the second positioning plate 22. When the second positioning plate 22 contacts the locking block 5, the displacement distance of the second positioning plate 22 is controlled by the limiting block 23, thereby improving the overall motion accuracy.

[0035] Figures 1 to 4 As shown, during operation, the wire harness is placed in the groove of the main body 2. The extension rod of the first cylinder 8 drives the drive plate 9 to cooperate with the clamping block 3, so that the clamping block 3 rotates around the hinge point and drives the wire harness to perform initial clamping.

[0036] After the clamping block 3 is initially clamped, the connecting rod 4 and the locking block 5 need to be locked by the clamping assembly.

[0037] The displacement module 7 drives the displacement plate 10 to move and drives the support frame 6 and the wire clamp to move toward the clamping assembly.

[0038] The second cylinder 18 drives the first positioning plate 20 to contact the connecting rod 4 and the locking block 5. This causes the locking block 5 and the connecting rod 4 to rotate around the hinge point. The telescopic rod of the third cylinder 21 is fixedly connected to a second positioning plate 22 that cooperates with the locking block 5. The moving plate 19 is fixedly connected to a guide rail that cooperates with the second positioning plate 22. The second positioning plate 22 also has rollers 24 that contact the locking block 5 and the connecting rod 4. When the second positioning plate 22 contacts the locking block 5, the displacement distance of the second positioning plate 22 is controlled by the limiting block 23, thereby locking the wire clamp assembly.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
