[0033] During the process of operating the device to clamp the workpiece, it is first necessary to start the hydraulic rod 14. The start of the hydraulic rod 14 will cause it to contract, thereby driving the connecting plate 15 to move accordingly. The movement of the connecting plate 15 will cause the slider 4 on one side to slide along the side wall of the fixed bar 3. The sliding of the slider 4 will further drive the rack 13 to slide accordingly. The sliding of the rack 13 will cause the gear 12 to rotate. The rotation of the gear 12 will cause the rack 13 on the other side to slide, thereby driving the slider 4 to slide. The sliding of the slider 4 will cause it to drive the arc-shaped clamping blocks 7 on both sides to move closer to the middle until the arc-shaped clamping blocks 7 on both sides completely fit the side wall of the workpiece, so as to achieve the effect of effectively fixing the workpiece. When the light is poor, the electric lamp 11 can be turned on to illuminate the workbench 1. The flexible support rod 10 can be freely adjusted according to needs.

[0034] Refer to Figure 1 and Figure 4 , a first mounting block 16 is fixedly connected to the side wall of the mounting plate 6, and a second mounting block 17 is fixedly connected to the side wall of the arc-shaped clamping block 7. The cooperation between the first mounting block 16 and the second mounting block 17 facilitates the quick installation of the clamping block. A sliding rod 18 is slidably connected inside the first mounting block 16. The sliding rod 18 is used to push the capping 23 to move. One end of the sliding rod 18 is fixedly connected to the capping 23. The side wall of the capping 23 is slidably connected inside the second mounting block 17. A fixed sleeve 19 is fixedly connected inside the first mounting block 16. The side wall of the sliding rod 18 is slidably connected inside the fixed sleeve 19. A first fixing ring 20 is fixedly connected to the side wall of the sliding rod 18. A first spring 21 is sleeved on the side wall of the sliding rod 18. The first spring 21 is used to push the sliding rod 18 to slide. One end of the first spring 21 is fixedly connected to the side wall of the first fixing ring 20, and the other end of the first spring 21 is fixedly connected inside the first mounting block 16. A second fixing ring 22 is fixedly connected to the side wall of the sliding rod 18. A second spring 24 is sleeved on the side wall of the sliding rod 18. The second spring 24 is used to push the sliding block 25 to slide. One end of the second spring 24 is fixedly connected to the side wall of the capping 23, and the other end of the second spring 24 is fixedly connected to a sliding block 25. The sliding block 25 is slidably connected to the side wall of the sliding rod 18. A fixing block 26 is fixedly connected to the side wall of the second mounting block 17. A sliding column 27 is slidably connected inside the fixing block 26. The side wall of the sliding column 27 is slidably connected inside the second mounting block 17. One end of the second mounting block 17 is fixedly connected to a rectangular clamping block 29. The rectangular clamping block 29 is used to clamp the capping 23. A third spring 28 is sleeved on the side wall of the second mounting block 17. The third spring 28 is used to push the sliding column 27 to slide. One end of the third spring 28 is fixedly connected to the side wall of the rectangular clamping block 29, and the other end of the third spring 28 is fixedly connected inside the second mounting block 17.

[0035] When the arc-shaped clamping block 7 needs to be replaced, first, the sliding rod 18 needs to be pressed to make it slide. This action will apply pressure to the first spring 21, thereby pushing the sliding block 25 to move. During the movement of the sliding block 25, it will apply pressure to the rectangular clamping block 29, pushing the sliding column 27 to move backward. This backward movement will cause the third spring 28 to be squeezed and contract. As the third spring 28 contracts, the sliding block 25 can pass through the rectangular clamping block 29. At this time, release the sliding rod 18, and the first spring 21 will lose the extrusion and thus rebound. The sliding rod 18 moves upward under the rebound action of the first spring 21, driving the sliding block 25 to slide and fit the cap 23. Subsequently, the second spring 24 rebounds under the drive of the sliding block 25. Through the resilience of the first spring 21, the sliding block 25 applies pressure to the rectangular clamping block 29 again, making it move backward, thereby releasing the fixation of the cap 23. In this way, the arc-shaped clamping block 7 can be easily removed and replaced. The quick replacement of the fixture significantly shortens the downtime. This support for the quick switching of a variety of different fixtures enables the machining center to adapt to diverse production requirements, enhancing the flexibility of the production line. At the same time, the standardized design of the fixture quick-change device helps to reduce the manufacturing cost of the fixture.

[0036] Working principle: When using this device to clamp a workpiece, first start the hydraulic rod 14 to make it contract and drive the connecting plate 15 to move, so that one side of the slider 4 slides on the side wall of the fixed strip 3, driving the rack 13 to slide, making the gear 12 rotate, and then making the rack 13 on the other side slide, driving the slider 4 to slide, and then driving the arc-shaped clamping blocks 7 on both sides to move closer to the middle until they fit the side wall of the workpiece, achieving the fixation effect. When the arc-shaped clamping block 7 needs to be replaced, press the sliding rod 18 to make it slide, squeeze the first spring 21, thereby pushing the sliding block 25 to move, making it squeeze the rectangular clamping block 29, pushing the sliding column 27 to move backward, making the third spring 28 squeeze and contract, so that the sliding block 25 can pass through the rectangular clamping block 29. Then release the sliding rod 18, let the first spring 21 lose the extrusion and rebound, pull the sliding rod 18 upward, so that the sliding block 25 slides and fits the cap 23, making the second spring 24 squeeze and rebound. Through the resilience of the first spring 21, let the sliding block 25 squeeze the rectangular clamping block 29 again, so that it moves backward, releasing the fixation of the cap 23, and then the arc-shaped clamping block 7 can be removed for replacement.
