[0030] Please combine Figs. 1 to 4 As shown, this utility model provides an automatic switching fixture for final assembly grippers.

[0031] In one exemplary embodiment of this application, the automatic switching fixture for assembling the clamp 1 includes:

[0032] The gripper 1 includes a front leg 101 and a rear leg 102. The front leg 101 is provided with a tray 2, and the rear leg 102 is provided with a support block 3, an adjusting component 4, and a locking mechanism 5. The tray 2 and the support block 3 are used to lift the workpiece. The adjusting component 4 is hinged to the support block 3 and the rear leg 102. The adjusting component 4 is used to rotate with the rear leg 102 to adjust the position of the support block 3. The locking mechanism 5 is used to cooperate with the adjusting component 4 to restrict the rotation of the adjusting component 4 and the rear leg 102.

[0033] Positioning module 6 is used to cooperate with front leg 101 to position gripper 1 and switching fixture;

[0034] The switching module includes an unlocking mechanism 7 and a switching mechanism 8. The unlocking mechanism 7 is used to unlock the locking mechanism 5, and the switching mechanism 8 is used to push the support block 3 to rotate the adjusting component 4 and the rear leg 102 to switch the position of the support block 3.

[0035] In this embodiment, by setting the adjustment component 4 and the locking mechanism 5, in conjunction with the unlocking mechanism 7 and the switching mechanism 8 in the switching module, the position of the support block 3 on the rear leg 102 of the gripper 1 is automatically adjusted without manual intervention, effectively improving switching efficiency and reducing the labor intensity of personnel. By setting the positioning module 6 to cooperate with the front leg 101 of the gripper 1, the accurate position of the gripper 1 during the switching process is ensured, limiting the shaking of the gripper 1, improving the consistency and stability of the tooling, and avoiding positioning deviations caused by human operation errors. This application, by automatically switching the position of the support block 3, enables the gripper 1 to quickly adapt to the needs of different vehicle lengths, shortens the changeover time, improves the flexibility and versatility of the production line, and reduces the time cost of manual adjustment.

[0036] In an exemplary embodiment of this application, the tray 2 is provided with a positioning hole 201, and the positioning module 6 is provided with a positioning pin 601, the positioning hole 201 and the positioning pin 601 are engaged.

[0037] In this embodiment, the positioning hole 201 on the tray 2 cooperates with the positioning pin 601 on the positioning module 6 to ensure the positioning accuracy of the gripper 1 and the switching fixture, limit the shaking of the gripper 1, improve the consistency and stability of the fixture, and avoid positioning deviation caused by human operation error.

[0038] In an exemplary embodiment of this application, the adjusting component 4 is provided with bushings 401 at both ends along the length direction, and the rear leg 102 and the support block 3 are provided with shaft holes, which are connected to the bushings 401 by pins.

[0039] In this embodiment, the bushing 401 on the adjusting component 4 is connected to the shaft hole on the rear leg 102 and the support block 3 by a pin, so that the adjusting component 4 is rotatably connected to the rear leg 102 and the support block 3 respectively. By rotating the adjusting component 4 and the rear leg 102, the position of the support block 3 can be adjusted. After the position of the support block 3 is adjusted, the support block 3 can be rotated with the adjusting component 4 so that the support block 3 meets the state when it is in contact with the workpiece.

[0040] In an exemplary embodiment of this application, the locking mechanism 5 includes a locking block 501 and a locking block 502. The locking block 501 is disposed on the adjusting member 4, and the locking block 502 is rotatably disposed on the rear leg 102. The locking block 502 is used to engage with the locking block 501 to lock and fix the position of the support block 3.

[0041] In this embodiment, after the adjusting component 4 and the rear leg 102 rotate to adjust the position of the support block 3, the locking block 502 and the latching block 501 engage to fix the adjusting component 4 in its current position. This prevents the position of the support block 3 from changing and affecting the lifting of the workpiece if there is no locking structure between the adjusting component 4 and the rear leg 102 during the operation of the gripper 1. Since the locking block 502 is rotatably connected to the rear leg 102, rotating the locking block 502 allows switching between the engaging and unlocking states of the locking block 502 and the latching block 501.

[0042] In an exemplary embodiment of this application, the locking block 502 is provided with a snap-fit ​​portion 502a, and the snap-fit ​​block 501 is provided with a snap-fit ​​groove 501a, wherein the snap-fit ​​portion 502a engages with the snap-fit ​​groove 501a.

[0043] In this embodiment, the locking block 502 and the rear leg 102 are rotatably connected by a hinge shaft. The locking block 502 is provided with a locking pin, which engages with the locking groove 501a on the locking block 501 to achieve the locking state of the adjusting component 4 and fix the position of the support block 3.

[0044] In an exemplary embodiment of this application, a torsion spring 502b is provided on the locking block 502, and the torsion spring 502b is used to maintain the locking state between the locking part 502a and the locking groove 501a.

[0045] In this embodiment, the torsion spring 502b is fixed on the hinge shaft between the locking block 502 and the rear leg 102, generating an initial preload torque. This ensures that the locking portion 502a of the locking block 502 always maintains a tendency to rotate towards the slot 501a, maintaining the locking state even under vibration or impact. During the workpiece handling process of the gripper 1, the torsion spring 502b ensures that the locking portion 502a and the slot 501a remain locked, preventing accidental unlocking. When the unlocking mechanism 7 releases the actuating part 502c, the torsion spring 502b automatically drives the locking block 502 to reset, requiring no manual intervention.

[0046] In an exemplary embodiment of this application, the locking block 502 is provided with a toggle part 502c, which is used to drive the locking block 502 and the rear leg 102 to rotate, so as to release the latching state between the latching part 502a and the slot 501a.

[0047] In this embodiment, the actuating part 502c is an extension arm of the locking block 502. The actuating part 502c and the hinge shaft form a lever structure. When the unlocking mechanism 7 acts on the actuating part 502c, the actuating part 502c overcomes the preload torque of the torsion spring 502b, and the actuating part 502c rotates under force. The locking part 502a disengages from the slot 501a to achieve unlocking. When the driving force is removed, the restoring torque of the torsion spring 502b causes the actuating part 502c and the locking block 502 to return to the initial locking position.

[0048] In an exemplary embodiment of this application, the unlocking mechanism 7 is a clamping cylinder. The clamping arm 701 of the unlocking mechanism 7 cooperates with the actuating part 502c to release the latching state between the latching part 502a and the slot 501a.

[0049] In this embodiment, after the gripper 1 is positioned and engaged with the positioning module 6, the rear leg 102 is located between the clamping arms 701 of the clamping cylinder. When the clamping cylinder is working, the clamping arms 701 close under air pressure, clamping the actuating part 502c, causing the actuating part 502c to rotate around the hinge axis, thereby disengaging the locking part 502a from the locking groove 501a, unlocking the locking block 502 and the locking block 501, and releasing the rotation restriction of the adjusting component 4 and the rear leg 102. At this time, the position of the support block 3 can be adjusted by rotating the adjusting component 4 and the rear leg 102 to meet the lifting operation of different vehicle models.

[0050] In an exemplary embodiment of this application, the switching mechanism 8 includes a base 801, a first switching component 802, and a second switching component 803. The first switching component 802 and the second switching component 803 are disposed on the base 801. The first switching component 802 is used to push the support block 3 to move along a first direction, and the second switching component 803 is used to push the support block 3 to move along a second direction. The first direction is opposite to the second direction.

[0051] In this embodiment, the first switching component 802 and the second switching component 803 are arranged in opposite directions, corresponding to the two extreme positions of the support block 3 (i.e., the long vehicle position and the short vehicle position). When switching the position of the support block 3, the unlocking mechanism 7 releases the locking state of the adjusting component 4 and the rear leg 102, and selects to operate the first switching component 802 or the second switching component 803 according to the target vehicle model, thereby completing the automatic switching of the support block 3 position to adapt to the lifting operation of different vehicle models.

[0052] In an exemplary embodiment of this application, the first switching component 802 includes a first cylinder 802a and a first push block 802b, wherein the first cylinder 802a is used to drive the first push block 802b to move along a first direction; the second switching component 803 includes a second cylinder 803a and a second push block 803b, wherein the second cylinder 803a is used to drive the second push block 803b to move along a second direction; the first push block 802b and the second push block 803b are both slidably disposed on the base 801 and abut against the support block 3.

[0053] In this embodiment, a guide rail is provided on the base 801, and the first push block 802b and the second push block 803b are both mounted on the guide rail, which guides the movement of the first push block 802b and the second push block 803b. The first cylinder 802a and the second cylinder 803a are arranged on the base 801 in opposite directions. When the cylinder is vented, the air pressure pushes the piston of the cylinder head to move, causing the push block to move linearly along the guide rail. When it is necessary to switch the support block 3 to the support position of the first target vehicle model, the first cylinder 802a extends, pushing the first push block 802b to move in the first direction. The thrust is transmitted through the contact surface between the first push block 802b and the support block 3, causing the adjusting component 4 to rotate around the hinge axis until the support block 3 reaches the support position of the first target vehicle model. Then, the unlocking mechanism 7 releases the locking block 502, and the locking mechanism 5 resets and locks the position of the support block 3. When it is necessary to switch the support block 3 to the support position of the second target vehicle, the second cylinder 803a extends, drives the second push block 803b to move in the second direction, causes the adjusting component 4 to rotate in the opposite direction, and drives the support block 3 to move to the position of the second target vehicle, thus completing the switching.

[0054] The working principle involves setting up an adjustment component 4 and a locking mechanism 5, which, in conjunction with the unlocking mechanism 7 and the switching mechanism 8 in the switching module, automatically adjust the position of the support block 3 on the rear leg 102 of the gripper 1. This eliminates the need for manual intervention, effectively improving switching efficiency and reducing labor intensity. By setting up a positioning module 6 that works in conjunction with the front leg 101 of the gripper 1, the accurate position of the gripper 1 during the switching process is ensured, limiting its sway and improving the consistency and stability of the tooling, thus avoiding positioning deviations caused by human error. This application, through automatic switching of the support block 3 position, allows the gripper 1 to quickly adapt to the needs of different vehicle lengths, shortening changeover time, improving the flexibility and versatility of the production line, and reducing the time cost of manual adjustments.

[0055] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
