[0022] Working principle: A base plate 2 is fixedly installed at the bottom of the main support column 1. Four supports are fixedly installed on the outer side of the base plate. The four supports support the base plate and can distribute the load. At the same time, the multi-point anti-tilt design ensures processing stability. A slide is opened on the surface of the base plate 2. A moving ring 4 is installed in the slide. A secondary support column 5 is fixedly installed on the surface of the moving ring 4. The secondary support column 5 moves horizontally on the slide of the base plate 2 through the moving ring 4 to realize the processing position adjustment. It is compatible with multiple size springs and can flexibly adjust the horizontal position of the processing rod 16 to meet the processing requirements of different specifications. A first fixed plate 15 is installed on the top of the secondary support column 5. A movable shaft 8 is installed inside the first fixed plate 15. The processing rod 16 is installed on the surface of the movable shaft 8 and is hinged to the top of the secondary support column 5 through the movable shaft 8. The first fixed plate 15 forms a lever structure, which can better process the parts. The first connecting rod 7 is movably installed inside the processing rod 16. The cover plate 14 is installed on the left side inside the processing rod 16. The second spring 13 is fixedly installed on the surface of the first connecting rod 7 and is connected to the cover plate 14. A rotating device is fixedly installed at one end of the first connecting rod 7. A baffle 6 is fixedly installed on the right side of the rotating device. By pulling the baffle 6, the clamp 24 can be closed. Twisting the baffle 6 can fix the position, allowing workers to concentrate on processing. When the second spring 13 is not in use, it causes the baffle 6 to spring back to its original position, driving the clamp 24 to open, reducing manual labor and improving the efficiency of spring production. The top of the main support column 1 is equipped with a second fixed plate 17. The second fixed plate 17 is fixedly installed with... A movable rod 21 has a reinforcing block 22 fixedly installed at one end. A fixed block 20 is installed at the top of the main support column 1. A second connecting rod 9 is installed at the bottom of the fixed block 20. First fixed shafts 19 are fixedly installed on both sides of the fixed block 20. The first fixed shafts 19 and the second fixed shafts 23 are movably connected by a linkage block 18. A fixing ring 12 is movably installed on the lower side of the surface of the second connecting rod 9. A pull rod 10 is fixedly installed on the surface of the fixing ring 12. After pulling the pull rod 10, the reinforcing block 22 is driven to close to fix the spring piece through the combined transmission of the second connecting rod 9, the first fixed shaft 19, the second fixed shaft 23, the linkage block 18, and the fixed block 20. The combination of the movable rod 21 and the second fixing plate 17 maintains the stable position of the reinforcing block 22. The bottom of the inner wall of the main support column 1 A first spring 11 is fixedly installed and is fixedly connected to a second connecting rod 9. When the second connecting rod 9 is pressed down, it compresses the first spring 11. After release, the spring pushes to automatically reset, reducing manual intervention and improving efficiency. A connecting block 25 is fixedly installed at one end of the processing rod 16. A third fixed shaft 27 is fixedly installed on the surface of the connecting block 25. A clamping plate 24 is movably installed on the surface of the third fixed shaft 27. A third connecting rod 26 is fixedly installed at the other end of the first connecting rod 7. The third connecting rod 26 is fixedly connected to the clamping plate 24. The connecting block 25 at the end of the processing rod 16 controls the opening and closing of the clamping plate 24 through the third fixed shaft 27. The third connecting rod 26 links the first connecting rod 7 and the clamping plate 24, achieving a labor-saving and efficient lever amplification effect, obtaining high clamping force with a small input force.Anti-slip patches are evenly installed on the right side surface of the processing rod 16 to increase grip friction and reduce the risk of slippage during operation. Four supports 3 are symmetrically fixed on the outer side of the base plate 2 to provide stable support and distribute the load.
[0023] In one aspect of this embodiment, a rotating device is fixedly installed at one end of the first connecting rod 7, and a baffle 6 is fixedly installed on the right side of the rotating device. The rotating device enables the baffle 6 to rotate, thereby locking the first connecting rod 7 so that it will not spring back. A second spring 13 is fixed to the surface of the first connecting rod 7. The second spring 13 is connected to the cover plate 14. The second spring 13 can retract when the baffle 6 returns to its original position, thereby opening the clamping plate 24, reducing manual intervention and improving efficiency.
[0024] In one aspect of this embodiment, a fixing ring 12 is movably mounted on the lower side of the surface of the second connecting rod 9, and a pull rod 10 is fixedly mounted on the surface of the fixing ring 12. After the part to be processed is placed into the reinforcing block 22, the pull rod 10 can be pulled to drive the linkage device (linkage block 18, first fixed shaft 19, fixing block 20, movable rod 21, second fixed shaft 23) to fix the part. A first spring 11 is fixed at the bottom of the main support column 1. The first spring 11 is fixedly connected to the second connecting rod 9. The first spring 11 can open the reinforcing block 22 when the device is not in use, thereby improving efficiency.
[0025] In one aspect of this embodiment, four supports 3 are symmetrically installed on the outer side of the base plate 2. The supports 3 serve as the support base for the entire equipment, distributing the load when the fixture is working and ensuring the stable operation of the equipment. Anti-slip patches are evenly distributed on the surface of the processing rod 16. The anti-slip patches increase the surface friction and prevent the operator's hands from slipping, ensuring precise control of the processing rod 16, while reducing the risk of accidental slippage and protecting the operator and the equipment.
[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
