[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 This utility model provides a technical solution: a deformation-resistant fixture for thin-walled parts in CNC machining, comprising a fixed platform 1, a filling mechanism for filling a clamped pipe is provided on one side of the surface of the fixed platform 1, the filling mechanism comprising a fixed plate 2, a connecting rod 3, a movable sleeve 4, a support rod 5, a support plate 6, and a transmission rod 7. The fixed plate 2 is fixedly provided on one side of the surface of the fixed platform 1, the connecting rod 3 is fixedly provided on the surface of the fixed plate 2, the movable sleeve 4 is movably sleeved on one side of the surface of the connecting rod 3, the support rod 5 is movably provided on the surface of the connecting rod 3 via a rotating shaft, the support plate 6 is movably provided on the end of the support rod 5 away from the connecting rod 3 via a rotating shaft, and the transmission rod 7 is movably provided on the surface of the support rod 5 via a rotating shaft, the end of the transmission rod 7 near the support rod 5 being movably connected to the support rod 5 via a rotating shaft.

[0021] A first nut 8 is screwed onto one side of the surface of the connecting rod 3. The first nut 8 is movably engaged with the movable sleeve 4 through an annular groove, so that the first nut 8 can rotate around the connecting rod 3 while driving the movable sleeve 4 to move along the connecting rod 3. When it is necessary to support the support plate 6, the first nut 8 can be rotated with a wrench or other tools, so that the first nut 8 moves along the connecting rod 3 towards the support rod 5 under the action of the thread. At this time, the first nut 8 can push the movable sleeve 4 towards the support rod 5. Then, the transmission rod 7 on the surface of the movable sleeve 4 can push the support rod 5, so that the support plates 6 are separated and opened up, thereby opening up the inside of the clamped pipe. This can effectively prevent the thin-walled parts from deforming when they are clamped and fixed, thus improving the clamping and fixing effect of the device.

[0022] The upper end of the fixed platform 1 is provided with clamping mechanisms for clamping parts on both sides. The clamping mechanism includes a sliding groove 9, a clamping block 10, and a screw 11. The surface of the fixed platform 1 is provided with a sliding groove 9. The clamping blocks 10 are movably engaged on both sides of the sliding groove 9. The screw 11 is movably arranged in the middle of the inner side of the fixed platform 1 through a bearing. The clamping blocks 10 are movably sleeved on the outer surface of the screw 11 through threads. With the clamping mechanism, the pipe can be clamped and fixed by using two clamping blocks 10 that are close to each other, just like in the prior art.

[0023] The screw 11 has opposite threads on both sides of its surface. When the screw 11 with opposite threads rotates, it can drive the two clamping blocks to move in opposite directions. At this time, the clamping block 10 can clamp and fix the pipe that needs to be clamped and fixed.

[0024] A second nut 12 is fixedly provided at one end of the screw 11. The screw 11 can be easily rotated through the second nut 12, thereby driving the two clamping blocks 10 to move closer to each other through the screw 11.

[0025] The surface of the fixed platform 1 is provided with mounting holes 13, through which the device can be easily fixed and installed at the target position.

[0026] Working principle: When using this device, the pipe is clamped by two clamping blocks 10 that are close to each other. The filling mechanism of this device is exactly in the center between the two clamping blocks 10. At this time, the pipe to be clamped and fixed is first placed on the surface of the support plate 6. Then, the first nut 8 is rotated by the thread to move the first nut 8 towards the support rod 5. At this time, the transmission rod 7 can push the support rod 5 and the support plate 6 to open. In this way, the support plate 6 can support the inside of the pipe. Then, the clamping blocks 10 clamp and fix the pipe from the outside. This can prevent the thin-walled parts from deforming when they are clamped and fixed, thus improving the clamping and fixing effect of the device.
