Description

Technical Field

[0001] The utility model relates to the field of gear shaving processing of shaft parts, and more specifically, to a gear shaving clamping auxiliary tool for shaft parts. Background Art

[0002] Gear shaving is the process of trimming or processing the edges of teeth using specific mechanical or manual methods. Currently, during the gear shaving process, known shaft parts (such as gears) require a centering tool to clamp the workpiece from both ends. Since the center hole of the workpiece is not large, if the workpiece is large and heavy, it is difficult to align the centering tool with the tailstock centering tool by hand, resulting in damage to the gear end face and difficult clamping. If the workpiece is small, the center hole is also small, making it difficult to align and easily damage the workpiece end face during clamping. This can easily cause the workpiece to be scrapped or affect the quality of gear shaving. In addition, the alignment process takes a certain amount of time, and the clamping efficiency is not high.

DETAILED DESCRIPTION

[0019] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and convenience of description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Numerous modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.

[0020] like Figure 1-3As shown, the technical solution of the present invention provides a shaft-type gear shaving fixture, comprising a support portion 1 and a sleeve portion connected to the support portion 1. The sleeve portion includes two sleeve members 2 spaced apart and a connector 3 connecting the two sleeve members 2. The sleeve members 2 are detachably mounted on a spindle 4. The sleeve members 2 include a semicircular fixing seat and a semicircular retaining ring 22 movably mounted on the semicircular fixing seat. The support portion 1 is fixedly connected to one of the sleeve members 2 and has an arcuate support surface 11, which is concentrically arranged with the semicircular retaining ring 22.

[0021] The support portion 1 is used to support the shaft of the workpiece, and the sleeve portion is sleeved on the top shaft 4. The tops on both sides respectively abut the center holes of the workpiece shaft 5 to fix the workpiece. The support portion 1 and the sleeve portion of this solution cooperate with each other to achieve rapid docking of the shaft and the top, avoiding scratches on the surface of the workpiece shaft 5 caused by the top during manual docking, and at the same time improving the clamping efficiency of the workpiece. The arc-shaped support surface 11 is concentrically arranged with the semicircular retaining ring 22, and the inner diameter of the semicircular retaining ring 22 is adapted to the outer diameter of the top shaft 4. The above arrangement ensures that the end of the top is opposite to the center hole on the workpiece shaft 5.

[0022] During clamping, this solution first docks one end of the top shaft 4 with the center hole of one end of the workpiece shaft 5, and then places the other end of the workpiece shaft 5 on the support 1. During the clamping process, the top shaft 4 moves toward the workpiece shaft 5 to complete the centering and tightening.

[0023] After docking is complete, the auxiliary tool in this embodiment can be completely removed by moving the semicircular retaining ring 22. A receiving groove 23 is provided within the semicircular fixing seat 21. One end of the semicircular retaining ring 22 is located within the receiving groove 23, and the semicircular retaining ring 22 can be moved in a direction extending from or into the receiving groove 23. When the semicircular retaining ring 22 extends into the semicircular fixing seat 21, the connection with the top shaft 4 can be released.

[0024] An elastic member is disposed within the receiving groove 23. One end of the elastic member abuts against the end of the semicircular retaining ring 22, while the other end abuts against the inner arm of the receiving groove 23. The elastic member is in a compressed state. The elastic member is a spring 24. The spring 24 automatically pushes the semicircular retaining ring 22 out of the receiving groove 23.

[0025] An arc-shaped limiting groove 25 is provided on one side of the semicircular fixing seat, and a limiting pin 26 is provided on the side of the semicircular snap ring 22. The limiting pin 26 is provided through the arc-shaped limiting groove 25. The limiting pin 26 and the limiting groove cooperate to limit the extension length of the semicircular snap ring 22.

[0026] The cross section of the semicircular snap ring 22 is circular, which reduces friction with the top shaft 4 and facilitates the movement of the semicircular snap ring 22. A return handle 27 is provided on the end of the semicircular snap ring 22 away from the semicircular fixing seat 21. When removing the auxiliary tool, the semicircular snap ring 22 can be pushed into the receiving groove 23 by the return handle 27 to achieve removal.

[0027] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making any creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in this utility model shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
