Abstract
Description
Technical Field
[0001] The invention relates to a clamping tool for turning inner holes of thin-walled parts, belonging to the technical field of mechanical processing fasteners. Background Art
[0002] In the past, we clamped the outer circle of thin-walled parts to adjust the clamping force and control the back cutting amount during turning to ensure product accuracy. During clamping, the thin-walled parts are easily deformed due to the thickness of the wall. When turning the inner hole, the thin-walled parts are easily elastically deformed due to the torque during the cutting process, resulting in the inability to ensure the accuracy of thin-walled parts and a high product scrap rate. After processing, the thin-walled parts need to be 100% inspected, which increases the production cost of the product and prolongs the production cycle. Summary of the invention
[0003] The present invention aims to solve the technical problems that thin-walled parts are easily deformed during clamping due to the influence of their wall thickness, and are easily elastically deformed due to the influence of torque during the cutting process when turning the inner hole, resulting in the inability to guarantee the accuracy of the thin-walled parts, a high scrap rate of the thin-walled parts, and the need to perform 100% inspection on the thin-walled parts after processing, which increases the production cost of the thin-walled parts and prolongs the production cycle. In order to solve the above technical problems, the present invention adopts the following technical solutions: A clamping tool for turning inner holes of thin-walled parts, comprising a clamping sleeve, a positioning screw, a positioning pin, a retaining ring, a spring chuck, and a limit screw; The inner conical surface of the inner hole of the jacket matches the outer conical surface of the spring chuck and is connected by a positioning pin; One end of the retaining ring is arranged at one end of the jacket through a positioning screw, and the other end of the retaining ring is arranged at the other end of the jacket through a limiting screw.
[0004] The beneficial effects of adopting the above technical solution are: The present invention can avoid deformation of the product during clamping and elastic deformation during turning, thereby improving the precision requirements of thin-walled parts, greatly reducing the scrap rate of thin-walled parts, and eliminating the need for 100% inspection of thin-walled parts, thereby reducing product production costs and shortening production cycles; the invention is simple to use and convenient for product disassembly; the processing is stable and reliable, improving product processing quality and reducing production costs; the clamping tooling is easy to process and manufacture and has low cost.

[0011] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0012] Thin-walled parts inner hole turning processing clamping tooling Figure 1 and Figure 2 As shown, it consists of a sleeve, a positioning screw, a positioning pin, a retaining ring, a spring collet and a limit screw.
[0013] like Figure 1 and Figure 2 As shown, one end of the retaining ring 4 is positioned by the positioning screw 2, and the other end is limited by the limit screw 6. After loosening the limit screw 6, the retaining ring 4 can be rotated clockwise to avoid the spring chuck 5, and the limit screw 6 will drive the spring chuck 5 to move longitudinally during the process of unscrewing, so that the product can be freely disassembled.
[0014] like Figure 3 As shown, the inner hole of the jacket 1 is an inner cone, as shown in FIG. Figure 4 As shown, the outer conical surfaces of the spring chuck 5 cooperate with each other to apply a clamping force to the jacket 1 during the clamping process. Figure 5 As shown, the thin-walled parts are uniformly stressed in the spring chuck 5, which can prevent the product from being deformed during clamping and elastically deformed during turning.
