The bottom of the ball bearing 6 is in contact with the upper surface of the base 1. The ball bearing 6 is symmetrically arranged on both sides of the fixed block 4. The ball bearing 6 can significantly reduce the frictional resistance when the clamp seat 5 moves, ensuring smooth position adjustment and reducing the load on the cylinder 2.

[0019] Specifically, the main fixed clamping head 7, the extended fixed clamping head 8, the main movable clamping head 9, and the extended movable clamping head 10 are all provided with a first internal cavity 16. The insertion rod 14 passes through the first internal cavity 16 and extends to the slot 12. The outer surface of the insertion rod 14 is adapted to the inside of the insertion hole 13, and the outer surface of the locking block 11 is adapted to the inside of the slot 12. The mechanical interlock is formed by the adaptation structure of the locking block 11 and the slot 12. After the insertion rod 14 passes through the first internal cavity 16 and is inserted into the insertion hole 13, the main clamping head and the extended clamping head can be quickly connected, providing a modular basis for the expansion of the clamping width.

[0020] Specifically, a fixing plate 17 is fixedly connected to the outer surface of the insertion rod 14. The fixing plate 17 is sleeved inside the first internal cavity 16. A pull block 15 is fixedly connected to the end of the insertion rod 14 away from the slot 12. The pull block 15 is located on the outside of the main fixed clamping head 7, the extended fixed clamping head 8, the main movable clamping head 9, and the extended movable clamping head 10. The fixing plate 17 limits the movement trajectory of the insertion rod 14 in the first internal cavity 16. The pull block 15 is exposed on the outside of the clamping head, so that the operator can directly apply force to pull the insertion rod 14, realize the one-handed unlocking operation of the snap-fit ​​structure, and improve loading and unloading efficiency.

The inner wall of the first internal cavity 16 is fixedly connected to a limit ring 19. The spring 18 forms an elastic reset mechanism, and the limit ring 19 constrains the maximum displacement of the fixing plate 17 to ensure that the insertion rod 14 remains axially positioned after it is disengaged from the insertion hole 13, and automatically springs back to the locked position when the pull block 15 is released.

[0022] Specifically, the fixture base 5 has a second internal cavity 21. A connecting block 20 is fixedly connected to the side of the main movable clamping head 9 near the fixture base 5. A screw 23 is rotatably connected inside the second internal cavity 21. The internal thread of the connecting block 20 is connected to the outer surface of the screw 23. A second guide groove 22 is provided on the inner wall of the second internal cavity 21. The outer surface of the connecting block 20 passes through the second guide groove 22. The connecting block 20 engages with the screw 23 through its internal thread and moves linearly under the restriction of the second guide groove 22, converting the rotation of the screw 23 into the vertical displacement of the main movable clamping head 9, thereby realizing the controllable application of the workpiece clamping force.

[0023] Specifically, a first bevel gear 24 is fixedly connected to the outer surface of the screw 23, a motor 25 is provided on the outer surface of the fixture seat 5, a second bevel gear 26 is fixedly connected to the rotating shaft of the motor 25, the second bevel gear 26 is located in the second internal cavity 21, the first bevel gear 24 and the second bevel gear 26 mesh, the motor 25 drives the second bevel gear 26 to mesh with the first bevel gear 24, and converts the axial rotation of the rotating shaft of the motor 25 into a transmission direction perpendicular to the screw 23.

[0024] The working principle of the above embodiments: In use, place the workpiece to be clamped on the main fixed clamping head 7, start the motor 25 to drive the second bevel gear 26 to rotate, the first bevel gear 24 rotates accordingly, driving the screw 23 to rotate, causing the connecting block 20 to move downward along the screw 23, driving the main movable clamping head 9 to move downward until it works with the main fixed clamping head 7 to clamp the workpiece. Controlling the extension and retraction of the cylinder 2 can drive the clamping seat 5 to move along the direction of the first guide groove 3, adjusting the two sets of clamping seats 5 to a suitable position to flexibly clamp workpieces of different lengths. During the movement of the clamping seat 5, the ball bearings 6 at its bottom roll on the upper surface of the base 1, reducing the resistance during the movement of the clamping seat 5. The clamping position is adjusted according to the width of the workpiece. Extended fixed clamping heads 8 can be installed on both sides of the main fixed clamping head 7, and extended movable clamping heads 10 can be installed on both sides of the main movable clamping head 9. The installation method is as follows: pull the pull block 15 outward to drive the insertion rod 14 to move, the fixing plate 17 moves accordingly, and the spring 18 is compressed until the fixing plate 17 moves to the limit ring 19 and the pull block 15 is stopped. At this time, the insertion rod 14 leaves the slot 12, so that the clamping block 11 is fully inserted into the slot 12. At this time, the insertion rod 14 is just aligned with the insertion hole 13. Release the pull block 15, and under the elastic force of the spring 18, the insertion rod 14 returns to its original position and is inserted into the insertion hole 13, so that the clamping block 11 is fixed in the slot 12, thereby making the two clamping heads firmly connected together.
