Abstract
Description
Technical Field
[0001] This utility model relates to the field of precision machining technology, and in particular to a device for preventing deformation during the processing of thin-walled sleeves. Background Technology
[0002] Currently, the clamping method for thin-walled sleeve parts during precision turning or precision grinding of the inner diameter is generally three-jaw chuck clamping. Using a hard three-jaw chuck clamping with a spindle results in a small force point on the three jaws, leading to uneven force distribution on the part and severe deformation after machining. Another clamping method is to replace the hard three-jaw chuck with a soft jaw, but the contact area between the soft jaw and the part is still limited, resulting in a large force that can still cause deformation of the machined part, making it unsuitable for precision machining.
[0003] However, the current clamping method is not convenient for clamping sleeve parts of different lengths, resulting in poor device performance. At the same time, because thin-walled sleeve parts are relatively thin, they cannot be effectively fixed during processing and are prone to deformation. Therefore, it is necessary to design a deformation prevention device for processing thin-walled sleeve parts. Utility Model Content

[0012] By adopting the above technical solution, and through the fixed connection between the spring and the outer cylinder and the outer arc clamp, the spring can achieve the purpose of elasticity.
[0013] The present invention is further configured such that: one end of the support rod is fixedly connected to a mounting bracket, and the outer surface of the mounting bracket is provided with a sliding groove.
[0014] By adopting the above technical solution and using the support rod, the mounting frame can be fixed, and the sliding groove can facilitate sliding.
[0015] The present invention is further configured such that: a bidirectional lead screw is rotatably connected to the inner wall of the mounting bracket, a nut is fixedly connected to one end of the bidirectional lead screw, a first sliding frame is threadedly connected to the outer surface of the bidirectional lead screw, and a second sliding frame is threadedly connected to the outer surface of the bidirectional lead screw.

[0019] Compared with the prior art, the present invention has the following beneficial effects:
[0020] 1. In this utility model, by setting up a knob, a bidirectional threaded rod, a first bracket, a second bracket, a slide rail, and an outer cylinder, when it is necessary to support parts of different lengths, the knob can be held by hand and rotated to drive the bidirectional threaded rod to rotate. By using the rotation of the bidirectional threaded rod, the first bracket and the second bracket can be slidably adjusted using the slide rail, thereby allowing the outer cylinder to support and fix the parts.

[0030] In practical use, when it is necessary to support parts of different lengths, hold the knob 5 by hand and turn it to drive the bidirectional threaded rod 4 to rotate. By using the rotation of the bidirectional threaded rod 4, the first bracket 6 and the second bracket 7 can be slidably adjusted using the slide rail 3, so that the outer cylinder 8 can support and fix the parts.
[0031] In this embodiment, the outer surfaces of the first bracket 6 and the second bracket 7 are both fixedly connected with support rods 9, and the first bracket 6 and the second bracket 7 are both slidably connected to the slide rail 3.
[0032] In practical use, the first bracket 6 and the second bracket 7 can be adjusted by using the slide rail 3 to facilitate sliding.
[0033] In this embodiment, a telescopic rod 10 is fixedly connected to the inner wall of the outer cylinder 8, and an outer arc clip 11 is fixedly connected to one end of the telescopic rod 10. A spring 12 is provided on the outer surface of the telescopic rod 10.
[0034] In practical use, when adjusting, when the outer arc clip 11 is close to the outer surface of the part, the telescopic rod 10 can drive the outer arc clip 11 to retract. When adjusted to a suitable distance, the reaction force of the spring 12 can cause the telescopic rod 10 to drive the outer arc clip 11 to spring back, thereby fixing and supporting the part.
[0035] In this embodiment, one end of the spring 12 is fixedly connected to the outer cylinder 8, and the other end of the spring 12 is fixedly connected to the outer arc clip 11.
[0036] In practical use, the spring 12 is fixedly connected to the outer cylinder 8 and the outer arc clip 11, so that the spring 12 can have the purpose of elasticity.
[0037] In this embodiment, one end of the support rod 9 is fixedly connected to the mounting bracket 13, and the outer surface of the mounting bracket 13 is provided with a sliding groove 14.
[0038] In practical use, the support rod 9 can be used to support the mounting bracket 13, and the slide groove 14 can facilitate sliding.
[0039] In this embodiment, a bidirectional lead screw 15 is rotatably connected to the inner wall of the mounting bracket 13. A nut 16 is fixedly connected to one end of the bidirectional lead screw 15. A first sliding bracket 17 is threadedly connected to the outer surface of the bidirectional lead screw 15, and a second sliding bracket 18 is threadedly connected to the outer surface of the bidirectional lead screw 15.
[0040] In practical use, when it is necessary to support the parts, use a tool to clamp the nut 16 and rotate it, which can drive the double-acting screw 15 to rotate. The rotation of the double-acting screw 15 can drive the first sliding frame 17 and the second sliding frame 18 to be adjusted.

[0043] Working principle: In use, when supporting parts of different lengths, hold the knob 5 and rotate it to rotate the bidirectional threaded rod 4. The rotation of the bidirectional threaded rod 4 allows the first bracket 6 and the second bracket 7 to slide and adjust using the slide rail 3, thus enabling the outer cylinder 8 to support and fix the part. During adjustment, when the outer arc-shaped clip 11 is close to the outer surface of the part, the telescopic rod 10 can retract the outer arc-shaped clip 11. When the appropriate distance is reached, the reaction force of the spring 12 allows the telescopic rod 10 to retract the outer arc-shaped clip 11. 11 rebounds, thus providing fixed support for the part. When support is needed, a tool is used to clamp the nut 16 and rotate it, which drives the double-acting screw 15 to rotate. The rotation of the double-acting screw 15 can drive the first sliding frame 17 and the second sliding frame 18 to adjust. When the first sliding frame 17 and the second sliding frame 18 are adjusted, they can slide using the slide groove 14. The first sliding frame 17 and the second sliding frame 18 can push the inner arc plate 19 to fit against the inner wall of the part, thereby achieving support for the part and preventing deformation during processing.
