[0022] Embodiment

[0023] Please refer to Figures 1-5 , the present utility model provides a technical solution: a clamping device for fixture processing that is convenient to adjust, including a clamping platform 1, a base 2 is installed on the clamping platform 1, adjusting components are arranged at both ends of the top of the base 2, and clamping components are arranged on the front and back sides of the clamping platform 1.

[0024] By setting the clamping assembly, the clamping of the fixture can be quickly completed; the clamping assembly includes a support arm 9 and an L-shaped frame 14. One side of the clamping platform 1 is provided with a fixed frame 7, and a fixed shaft 8 is fixedly connected inside the fixed frame 7. The support arm 9 is movably sleeved outside the fixed shaft 8. A chute 10 is opened on one side of the support arm 9, and the fixed shaft 8 is located inside the chute 10. A first limit clamp 11 is installed at one end of the support arm 9. On the other side of the clamping platform 1, there are two support columns 12. A connecting shaft 13 is fixedly connected between the two support columns 12. The L-shaped frame 14 is movably sleeved outside the connecting shaft 13. A second limit clamp 15 is installed at one end of the L-shaped frame 14. A telescopic spring 16 is fixedly connected between one side of the L-shaped frame 14 and the bottom of the clamping platform 1. A top column 17 is fixedly connected to one side of the L-shaped frame 14 away from the telescopic spring 16; by moving the support arm 9 downward, due to the setting of the chute 10, one end of the support arm 9 drives the first limit clamp 11 to move above the fixture, and then one end of the support arm 9 drives the first limit clamp 11 to move downward, so that the first limit clamp 11 abuts against the top of the fixture, and the longitudinal fixation of the fixture can be completed; at the same time, the L-shaped frame 14 is reset under the action of the force of the telescopic spring 16, so that one end of the second limit clamp 15 abuts against one side of the fixture, thereby fixing the fixture horizontally.

[0025] When it is necessary to disassemble the processed fixture, the support arm 9 moves outside the fixed shaft 8. Under the action of the chute 10, the support arm 9 will move vertically upward for a certain distance, so that the first limit clamp 11 is separated from the top of the fixture and turns outward, so that the first limit clamp 11 is separated from above the fixture. At the same time, the L-shaped frame 14 rotates around the connecting shaft 13, and the second limit clamp 15 on the L-shaped frame 14 is separated from one side of the fixture. At this time, the processed fixture can be removed from the base 2.

[0026] By setting the adjustment assembly, the positioning of fixtures with different sizes can be carried out, which greatly improves the versatility of the device; the adjustment assembly includes two fixed columns 3, a threaded rod 4 and an adjustment column 5. The two fixed columns 3 are respectively fixedly connected to both ends of the top of the base 2. The threaded rod 4 movably penetrates through one side of the fixed column 3. The adjustment column 5 is movably connected to one end of the threaded rod 4. A baffle 6 is fixedly connected to one side of the top of the base 2. The threaded rod 4 is threadedly connected inside the fixed column 3, and a rotating block is fixedly connected to the other end of the threaded rod 4; according to the size of the fixture, by rotating the rotating block to drive the threaded rod 4 to rotate, one end of the threaded rod 4 pushes the adjustment column 5 to move on the base 2, and the distance between the two adjustment columns 5 is adjusted.

[0027] For quick clamping of the fixture, an electric push rod 18 is installed at the bottom of the clamping platform 1. The push rod of the electric push rod 18 is fixedly connected to a fixing plate 19. One end of the top of the fixing plate 19 is provided with a connecting column 20. One end of the connecting column 20 is hinged to the other end of the support arm 9. The top column 17 is located at the other end of the top of the fixing plate 19. The push rod of the electric push rod 18 can drive the fixing plate 19 to move up and down. During clamping, the push rod of the electric push rod 18 drives the fixing plate 19 to move downward, thereby driving the connecting column 20 to move downward. At this time, the connecting column 20 pulls the support arm 9 to move downward, and the top of the fixing plate 19 disengages from the bottom end of the top column 17. At this time, the L-shaped frame 14 is reset under the action of the force of the telescopic spring 16. After processing is completed, the push rod of the electric push rod 18 drives the fixing plate 19 to move upward. During this process, one end of the fixing plate 19 drives the connecting column 20 to move upward, causing the support arm 9 to move outside the fixed shaft 8. At the same time, one end of the fixing plate 19 abuts above the top column 17, pushing the L-shaped frame 14 to rotate around the connecting shaft 13.

[0028] During the working principle or structural principle, when processing the fixture, according to the size of the fixture, the rotary block is rotated to drive the threaded rod 4 to rotate. One end of the threaded rod 4 pushes the adjusting column 5 to move on the base 2. By adjusting the distance between the two adjusting columns 5, different-sized fixtures can be positioned, greatly improving the versatility of the device.

[0029] Place the fixture to be processed on the base 2, with one end thereof abutting between the baffles 6 and located between the two adjusting columns 5. Then, control the push rod of the electric push rod 18 to extend through the switch group. The push rod of the electric push rod 18 drives the fixing plate 19 to move downward, thereby driving the connecting column 20 to move downward. At this time, the connecting column 20 pulls the support arm 9 to move downward. Through the arrangement of the sliding groove 10, one end of the support arm 9 drives the first limit clamp 11 to move above the fixture. Then, one end of the support arm 9 drives the first limit clamp 11 to move downward, causing the first limit clamp 11 to abut against the top of the fixture, thus completing the longitudinal fixation of the fixture. At the same time, the top of the fixing plate 19 disengages from the bottom end of the top column 17. At this time, the L-shaped frame 14 is reset under the action of the force of the telescopic spring 16, causing one end of the second limit clamp 15 to abut against one side of the fixture, thereby fixing the fixture horizontally, and completing the clamping of the fixture. The operation is simple and convenient for processing the fixture.

[0030] After the fixture is processed, the push rod of the electric push rod 18 is reset by controlling the switch group. The push rod of the electric push rod 18 drives the fixing plate 19 to move upward. During this process, one end of the fixing plate 19 drives the connecting column 20 to move upward, so that the support arm 9 moves outside the fixed shaft 8. Under the action of the sliding groove 10, the support arm 9 will move vertically upward for a certain distance, so that the first limit fixture 11 disengages from the top of the fixture and turns outward, so that the first limit fixture 11 disengages from above the fixture. At the same time, one end of the fixing plate 19 abuts above the top column 17, pushing the L-shaped frame 14 to rotate around the connecting shaft 13. The second limit fixture 15 on the L-shaped frame 14 disengages from one side of the fixture. At this time, the processed fixture can be removed from the base 2.
