Description

Technical Field

[0001] This invention relates to the field of clamping equipment technology, and in particular to an intelligent clamping positioning and switching system based on a flexible anti-collision mechanism. Background Technology

[0002] As products become more standardized and platform-based, production lines also become more standardized. Different products on the same production line require different fixtures for switching production. During switching, tooling is typically transferred and installed using a movable fixture cart or fixture base plate. However, when the fixture cart is pushed into the base for positioning, the lack of a stable and reliable guiding structure makes it prone to offset, jamming, or lateral wobbling. This not only affects positioning accuracy but also causes rigid collisions between the fixture and the base, resulting in fixture wear. Over time, this reduces repeatability and affects the fixture's usability. Summary of the Invention

[0003] In view of this, the purpose of this invention is to propose an intelligent fixture positioning and switching system based on a flexible anti-collision mechanism to solve the problem that fixtures lack guidance during the switching process and are prone to displacement and collision.

[0004] To achieve the above objectives, the present invention provides an intelligent fixture positioning and switching system based on a flexible anti-collision mechanism, comprising a base and a fixture carriage. The fixture carriage is mounted on the base, and an anti-collision guide mechanism is provided in the middle of the base to guide the movement of the fixture carriage. A limiting clamping mechanism is provided on the base to fix the fixture carriage on the base. The anti-collision guide mechanism includes guide pulleys on both sides of the middle of the base, and a guide rod is installed in the middle of the lower side of the fixture carriage.

[0005] A further improvement is that multiple sets of guide pulleys are arranged at equal intervals.

[0006] A further improvement is that a guide block is provided on the side of the base corresponding to the guide pulley, and the guide block is inclined.

[0007] A further improvement is that the limiting clamping mechanism includes a limiting plate, a bracket is installed on one side of the base, the limiting plate is installed on the bracket, clamping cylinders are installed on both sides of the middle of the base, clamping blocks are connected to the clamping cylinders, and a stop is correspondingly provided on the lower side of the clamping carriage.

[0008] A further improvement is that a contact sensor is installed on the upper end of the bracket, and the contact sensor is electrically connected to the clamping cylinder.

[0009] A further improvement is that the limiting plate has a groove, a buffer plate is movably installed in the groove, and a buffer spring is connected between the buffer plate and the groove.

[0010] A further improvement is that a positioning cylinder is installed on the base, and two sets of positioning cylinders are provided. The two sets of positioning cylinders are installed at diagonal positions on the base, and positioning pins are installed on the positioning cylinders.

[0011] A further improvement is that slides are provided on both sides of the base, and pulleys are provided on both sides of the bottom of the clamping cart. The clamping cart moves on the base along the slides via the pulleys.

[0012] A further improvement is that guide seats are provided on both sides of the base.

[0013] The beneficial effects of this invention are as follows: By setting an anti-collision guide structure in conjunction with a guide rod, the accurate positioning of the clamping cart is ensured when it is pushed onto the base, reducing collisions; and by setting a limiting clamping mechanism, after the clamping cart is pushed into place, the clamping cylinder drives the clamping block to flip upward, so that the clamping cart is locked by the clamping block and the limiting plate, preventing the clamp from loosening and ensuring the stability of the clamp during use; after contact sensing by a contact sensor, the clamping cylinder is controlled to start clamping, ensuring that the clamping cart moves to the correct position, and intelligent sensing clamping ensures the accuracy of the position; and a positioning cylinder drives the positioning pin to insert into the positioning hole of the clamping cart to position the clamping cart, further ensuring the accuracy of the clamping cart's position.

[0019] like Figures 1-4 As shown, this embodiment provides an intelligent clamp positioning and switching system based on a flexible anti-collision mechanism, including a base 1 and a clamp carriage 2. The clamp carriage 2 is set on the base 1, and guide seats 18 are provided on both sides of the base 1. The guide seats 18 limit and guide the wheels of the clamp carriage 2, so that the clamp carriage 2 moves to the upper side of the base 1 along the guide seats 18.

[0020] A collision-resistant guide mechanism is provided in the middle of the base 1 to guide the movement of the clamping carriage 2. The collision-resistant guide mechanism includes guide pulleys 3 located on both sides of the middle of the base 1. The guide pulleys 3 are rotatably mounted on the base 1. Multiple sets of guide pulleys 3 are equidistantly arranged. Guide blocks 5 are installed on the sides of the base 1 corresponding to the guide pulleys 3 by fasteners. The guide blocks 5 are inclined and the two guide blocks 5 are distributed in a V-shape. A guide rod 4 is installed in the middle of the lower side of the clamping carriage 2 by fasteners. When the clamping carriage 2 moves onto the base 1, the guide rod 4 enters between the guide blocks 5. The guide blocks 5 limit and guide the movement of the guide rod 4. The guide rod 4 passes through the guide pulleys 3 and contacts them. The guide pulleys 3 guide the movement of the guide rod 4. The guide pulleys 3 are in contact with the sides of the guide rod 4 to increase the resistance during the movement, slow down the movement speed, and reduce the collision during movement.

[0021] The base 1 has slides 16 on both sides, and the clamping cart 2 has pulleys 17 on both sides of the bottom. When the clamping cart 2 moves onto the base 1, the pulleys 17 move with the clamping cart 2 and come into contact with the slides 16. The pulleys 17 move on the slides 16, and the clamping cart 2 moves smoothly on the base 1 through the slides 16 and the pulleys 17.

[0022] A limiting clamping mechanism is provided on the base 1 to fix the clamping cart 2 on the base 1. The limiting clamping mechanism includes a limiting plate 6. A bracket 7 is installed on one side of the base 1 by fasteners. The limiting plate 6 is installed on the bracket 7 by fasteners. The movement of the clamping cart 2 is limited by the limiting plate 6, so that the clamping cart 2 abuts against the limiting plate 6. A groove 11 is provided on the limiting plate 6. A buffer plate 12 is movably installed in the groove 11. A buffer spring 13 is connected between the buffer plate 12 and the groove 11. The buffer plate 12 buffers the contact between the clamping cart 2 and the limiting plate 6 to prevent the clamping cart 2 from colliding with the limiting plate 6.

[0023] Mounting seats are provided on both sides of the middle of the base 1. The clamping cylinder 8 is mounted on the mounting seats by fasteners. A clamping block 9 is connected to the clamping cylinder 8. The clamping cylinder 8 drives the clamping block 9 to rotate. The connection structure between the clamping cylinder 8 and the clamping block 9 is existing technology. A stop block 19 is installed on the lower side of the fixture carriage 2 by fasteners. After the fixture carriage 2 moves into position, the clamping cylinder 8 drives the clamping block 9 to rotate and contact the stop block 19. The movement of the fixture carriage 2 is limited by the clamping block 9 and the stop block 19. A contact sensor 10 is installed on the upper end of the bracket 7. The contact sensor 10 is electrically connected to the clamping cylinder 8. When the fixture carriage 2 contacts the limit plate 6, the contact sensor 10 senses the position of the fixture carriage 2, making the clamping more intelligent. The clamping cylinder 8 drives the clamping block 9 to rotate and contact the stop block 19, so that the fixture carriage 2 is clamped between the clamping block 9 and the limit plate 6, and the switching and installation of the fixture carriage 2 is completed quickly.

[0024] A positioning cylinder 14 is installed on the base 1. There are two sets of positioning cylinders 14, which are installed at opposite corners of the base 1. Positioning pins 15 are installed on the positioning cylinders 14. Positioning holes are opened at the bottom of the fixture carriage 2. After the fixture carriage 2 moves into place, the positioning cylinder 14 drives the positioning pins 15 to extend and insert into the holes at the bottom of the fixture carriage 2 to position the fixture carriage 2 and ensure the accuracy of the position of the fixture carriage 2.

[0025] When it is necessary to switch fixtures, first release the clamping block 9 from blocking the stop block 19, pull the old fixture carriage 2 out of the base 1, and then push the new fixture carriage 2 onto the base 1. The guide seat 18 guides and limits the wheels at the bottom of the fixture carriage 2 from both sides, so that the fixture carriage 2 moves in alignment with the base 1. After the fixture carriage 2 moves onto the base 1, it is buffered and guided by the guide block 5 and the guide pulley 3 in conjunction with the guide rod 4 at the bottom of the fixture carriage 2. When the fixture carriage 2 contacts the limit plate 6, the contact sensor 10 senses the fixture carriage 2, and the positioning cylinder 14 drives the positioning pin 15 to rise and insert into the positioning hole at the bottom of the fixture carriage 2 for positioning. The clamping cylinder 8 drives the clamping block 9 to rise and contact the stop block 19. The clamping block 9 and the limit plate 6 clamp and lock the fixture carriage 2, so that the fixture carriage 2 cannot move, ensuring the stability of the fixture positioning.
