Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a clamp switching quick-insertion mechanism. Background Art

[0002] In the automobile production process, when multiple models are produced on the same line, it is often necessary to switch welding fixtures of different models to achieve this. There are two main ways to switch fixtures: full set switching and partial switching. When switching a full set of fixtures, the labor intensity of employees is high, and a site is required to store the switched welding fixtures. The factory occupies a large area and has a low utilization rate. When switching partial fixtures, it is necessary to manually disassemble the fastening bolts. After repeated disassembly, the fixture wears quickly, and the time cost required for switching is high, which reduces production efficiency. Therefore, there is a defect of inconvenience in replacing the fixture, which cannot meet the customer's usage needs.

[0003] Therefore, those skilled in the art provide a clamp switching quick-insertion mechanism to solve the problems raised in the above background technology. Utility Model Content

[0004] In order to improve the problem of inconvenience in replacing a clamp, the utility model provides a clamp switching quick-insertion mechanism.

[0005] The utility model provides a fixture switching quick-insertion mechanism, which adopts the following technical solutions:

[0006] The cam is an angular channel that is fixedly connected to the locking cam of the locking cam, and a second cam is connected to the locking cam of the locking cam by a spring, and a first cam is connected to the locking cam of the locking cam by a spring.

[0007] By adopting the above technical solution, when it is necessary to switch the upper clamp and the lower clamp, the staff unplugs the first quick-plug reference pin and the second quick-plug reference pin in turn, thereby releasing the first limit of the first clamp standard joint and the second clamp standard joint, then, the staff presses the locking hook pin, so that the locking hook pin rotates around the movable axis to squeeze the spring, so that the locking hook pin moves away from the first clamp standard joint and the second clamp standard joint, thereby releasing the second limit of the first clamp standard joint and the second clamp standard joint, then, the staff takes the upper clamp and the lower clamp in turn, so that the upper clamp and the lower clamp drive the first clamp standard joint and the second clamp standard joint to move out of the inner cavity of the quick-plug support, and at the same time, the staff releases the locking hook pin, and at the same time, the spring, under the reaction force, pushes the locking hook pin to rotate in the opposite direction to restore to the initial state, thereby realizing the disassembly of the upper clamp and the lower clamp;

[0008] Then, the staff takes the replaced upper clamp and lower clamp, so that the upper clamp and the lower clamp drive the first clamp standard joint and the second clamp standard joint to be inserted into the inner cavity of the corresponding quick-insert support in turn. While the first clamp standard joint and the second clamp standard joint are inserted into the inner cavity of the corresponding quick-insert support, the first clamp standard joint and the second clamp standard joint push the locking hook pin to rotate obliquely upward to move the extrusion spring. When the first clamp standard joint and the second clamp standard joint are inserted into the specified position, the spring pushes the locking hook pin to rotate in the opposite direction under the reaction force and fits tightly with the connection between the first clamp standard joint and the second clamp standard joint, thereby realizing the rapid clamping of the first clamp standard joint and the second clamp standard joint, and realizing the first limit of the first clamp standard joint and the second clamp standard joint. Then, the staff inserts the first quick-insert reference pin and the second quick-insert reference pin in turn, so that the first quick-insert reference pin and the second quick-insert reference pin are inserted into the inner cavity of the pin hole, thereby realizing the second limit of the first clamp standard joint and the second clamp standard joint, thereby completing the rapid switching of the clamps.

[0009] Optionally, there are two sets of locking mechanisms, and the two sets of locking mechanisms are respectively located at the top and the right side of the front of the frame.

[0010] Optionally, the upper clamp is located on the right side of the top of the frame, the lower clamp is located below the upper clamp, and both the upper clamp and the lower clamp are clamped with the quick-insert support.

[0011] Optionally, the first clamp standard joint is fixedly connected to the left side of the upper clamp, and the second clamp standard joint is fixedly connected to the bottom of the lower clamp.

[0012] Optionally, the sensor is located on the right side of the front right quick-insertion support, and the sensor is fixedly connected to the connection between the bracket and the front right quick-insertion support.

[0013] Optionally, the number of the pin holes is four, and the pin holes are respectively arranged on both sides of the first clamp standard joint and the second clamp standard joint.

[0014] Optionally, the quick-insert support is fixedly connected to a frame, and a cylinder is fixedly connected to the left side of the frame.

[0015] By adopting the above technical solution and the arrangement of the cylinder, the frame can be driven conveniently.

[0016] Optionally, a mounting bracket is fixedly connected to the back of the rack, and the mounting bracket is L-shaped.

[0017] By adopting the above technical solution and setting up the mounting frame, it is possible to facilitate the installation and positioning of the device.

[0018] In summary, the utility model has the following beneficial effects:

[0019] 1. The utility model can facilitate the rapid replacement of the upper clamp and the lower clamp by arranging a quick-insert support, a locking hook pin, a spring, a first quick-insert reference pin, a cover plate, a second quick-insert reference pin, a first clamp standard joint, a second clamp standard joint and a pin hole. By arranging a sensor, the installation positions of the upper clamp and the lower clamp can be detected.

[0032] In this embodiment: The utility model can facilitate the rapid replacement of the upper clamp 3 and the lower clamp 4 by setting a quick-insert support 201, a locking hook pin 202, a spring 203, a first quick-insert reference pin 204, a cover plate 205, a second quick-insert reference pin 206, a first clamp standard joint 5, a second clamp standard joint 6 and a pin hole 7.

[0034] The implementation principle of the utility model is as follows: when the upper clamp 3 and the lower clamp 4 need to be switched and replaced, the staff unplugs the first quick-insert reference pin 204 and the second quick-insert reference pin 206 in sequence, thereby releasing the first limit of the first clamp standard joint 5 and the second clamp standard joint 6, and then presses the locking hook pin 202, so that the locking hook pin 202 rotates around the movable axis as the center of the circle to squeeze the spring 203, so that the locking hook pin 202 is away from the first clamp standard joint 5 and the second clamp standard joint The head 6 is pressed, thereby releasing the second limit of the first clamp standard joint 5 and the second clamp standard joint 6. Then, the staff takes the upper clamp 3 and the lower clamp 4 in turn, so that the upper clamp 3 and the lower clamp 4 drive the first clamp standard joint 5 and the second clamp standard joint 6 to move out of the inner cavity of the quick-insert support 201.
