[0019] Please see Figure 1-5 This utility model provides an embodiment of a fixture for automated mechanical production, comprising a housing 1, one end of which is provided with a pivot pin seat 8, and the pivot pin seat 8 is provided with a pivot pin rod 9; one side of the housing 1 is provided with a first gripper 5 and a second gripper 6, and the first gripper 5 and the second gripper 6 are rotatably mounted on the housing 1 by the pivot pin rod 9 passing through the pivot pin seat 8, the first gripper 5, and the second gripper 6; the housing 1 is also provided with a linkage 7, and the linkage 7 is slidable within the housing 1 by a drive motor 2 provided on the housing 1, so that the first gripper 5 and the second gripper 6 can be opened or closed.
[0020] In summary, the opening and closing of the two grippers can be achieved by sliding the linkage 7 inside the housing 1, allowing the two grippers to freely clamp the workpiece. Furthermore, the housing 1 can be installed in different positions; for example, if the housing 1 is installed vertically on the lifting platform, the grippers will point downwards, allowing the gripping points of the two grippers to clamp the workpiece. When the housing 1 is placed horizontally on the lifting platform, the middle of the two grippers can also be used to clamp the workpiece. Therefore, the device can be installed vertically or horizontally to clamp the workpiece, making the usage position of the device adjustable.
[0021] Furthermore, since the linkage 7 includes a collar 10, the inner hole of which is fitted onto the outer surfaces of the first gripper 5 and the second gripper 6, and slides on the inner wall of the housing 1 through the collar 10 to facilitate the closure of the first gripper 5 and the second gripper 6, thus making the structure for closing the two grippers simpler, simplifying the equipment and reducing production costs. In particular, the internal structure of the housing 1 is simple while completing the closing action of the two grippers, making it easy for users to maintain and repair, and the maintenance and repair are low in difficulty and require little expertise.
[0022] Furthermore, a spring plate 4 is provided between the facing surfaces of the first gripper 5 and the second gripper 6, and the spring plate 4 causes the first gripper 5 and the second gripper 6 to unfold. Therefore, by utilizing the cooperation between the spring plate 4 and the collar 10, the drive motor 2 only needs to rotate normally to complete the unfolding or closing of the two grippers, thus further simplifying the structure of the device.
[0023] In addition, since the collar 10 is connected to the threaded seat 12 via the connecting rod 11, and the threaded seat 12 is threadedly engaged with the output shaft of the drive motor 2 via the internal threaded hole 13, the structure of the linkage 7 is simplified. At the same time, the angle of the two grippers when unfolded can be adjusted by changing the length of the connecting rod 11.
[0024] To prevent the claw tips from misaligning after the two grippers engage, a slot 14 is provided in the middle of the first gripper 5, and the second gripper 6 rotates within this slot 14. Therefore, since the second gripper 6 rotates within the slot 14 of the first gripper 5, the gripping will not fail due to misalignment of the claw tips when the device uses the claw tips to grasp the workpiece.
[0025] Furthermore, since the outer side of the second gripper 6 is also provided with a protrusion 15, and the protrusion 15 is flush with the outer wall surface of the first gripper 5, when the two grippers grip the workpiece laterally, the protrusion 15 makes the sides of the two grippers flush, thereby ensuring that the contact area between the two grippers and the workpiece is the same, reducing the damage caused by the grippers to the outer wall of the workpiece.
[0026] To facilitate the installation of the housing 1, an installation plate 3 is provided on the outer wall of the housing 1. Therefore, the installation plate 3 can be fixed to the lifting seat by bolts passing through the installation plate 3, thus making the installation of the housing 1 simple and convenient. The lifting seat only needs to be able to make the entire device lift and lower.
[0027] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
