[0018] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0019] Example

[0020] Please refer to Figure 1 As shown, the utility model provides a sprocket seat four-axis clamp, including a fixed bottom plate 1, a placing table 4, an inclined support rod 3 is formed at the diagonal of the lower surface of the placing table 4, a mounting block 2 with a mounting hole is welded to the bottom end of the support rod 3, a retaining ring 13 is arranged inside the support rod 3, and the retaining ring 13 is sleeved on the outer side of the transmission plate 9. The setting of the retaining ring 13 can limit the transmission plate 9. When the transmission plate 9 moves, its upper end is retracted and close to each other, so as to drive the clamping block 7 to move. When the device is used, it is fixed by passing the fixing bolts through the mounting holes on the mounting block 2;

[0021] like Figure 1 - Figure 4 As shown, a placing platform 4 is arranged just above the fixed bottom plate 1, and a slide groove 5 is opened inwardly in the middle of each side of the placing platform 4, and a downward through groove 6 is opened on the bottom wall of the slide groove 5. A clamping block 7 is arranged inside the slide groove 5, and the clamping block 7 can slide in the slide groove 5. The inner end face of the clamping block 7 has an arc and an arc-shaped notch is formed on the upper surface. The design of the arc-shaped notch enables the clamping block 7 to clamp the original part from the outside and to support the original part from the inside of the punched original part to fix it. A connecting frame 8 is formed on the lower surface of the clamping block 7, and the connecting frame 8 passes through the through groove 6. The lower end of the connecting frame 8 is connected to a driving component. The driving component The parts include a transmission plate 9, a lifting frame 10, a screwing nut 11, and a fixing stud 12. A vertical fixing stud 12 is arranged in the middle of the upper surface of the fixed bottom plate 1. The fixing stud 12 is provided with a screwing nut 11 screwed therewith. The upper end of the screwing nut 11 is movably connected with a rotatable lifting frame 10. Another group of connecting frames 8 corresponding to the position of the connecting frames 8 on the lower surface of the clamping block 7 are formed on the side of the lifting frame 10. The connecting frames 8 are connected by the transmission plate 9. The connecting frame 8 is composed of two fixed plates and a fixed shaft. The two ends of the transmission plate 9 are penetrated by the fixed shaft and the two are independent of each other. The transmission plate 9 rotates along the fixed shaft as a whole.

[0022] When fixing the original sprocket seat, first rotate the screw-on nut 11, and the screw-on nut 11 rotates and screws with the fixing stud 12, so that the screw-on nut 11 drives the lifting frame 10 to move downward, thereby pulling the transmission plate 9 to cooperate with the connecting frame 8 to make the clamping block 7 slide in the slide groove 5. At this time, the lower end of the transmission plate 9 moves downward and the plate body of the transmission plate 9 is blocked by the outer retaining ring 13, and the heads are close to each other, driving the clamping blocks 7 to move closer to each other until the space formed between the clamping blocks 7 is slightly larger than the size of the original sprocket seat. The original sprocket seat is placed on the clamping block 7, and the screw-on nut 11 is continued to be rotated to clamp the original sprocket seat.

[0023] Specific working principle:

[0024] When using the device, fix it by passing the fixing bolt through the mounting hole on the mounting block 2, and then rotate the screwing nut 11, the screwing nut 11 rotates and screws with the fixing stud 12, so that the screwing nut 11 drives the lifting frame 10 to move downward, thereby pulling the transmission plate 9 to cooperate with the connecting frame 8 to make the clamping block 7 slide in the slide groove 5. At this time, the lower end of the transmission plate 9 moves downward and the plate body of the transmission plate 9 is blocked by the outer retaining ring 13, and the heads are close to each other, driving the clamping blocks 7 to approach each other until the space formed between the clamping blocks 7 is slightly larger than the size of the original sprocket seat. The original sprocket seat is placed on the clamping block 7, and the screwing nut 11 is continued to be rotated to clamp the original sprocket seat, and the non-side part of the original sprocket seat can be processed. When the side of the original sprocket seat needs to be processed, the reverse operation is performed to make the clamping blocks 7 move away from each other, and the notch at the upper end of the clamping block 7 is used to contact with the inside of the original sprocket seat, and the original sprocket seat is fixed by moving the clamping block 7 outward.

[0025] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
