Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Examples
Referring to fig. 1, the present embodiment provides a shaft hobbing and shifting tool, which includes a thimble seat 3, a shifting sleeve 1, a thimble 2, a spring 4 and an adjusting cover 5.
Wherein, the middle of the thimble seat 3 is provided with a central hole 6 which is through along the axial direction, and the shifting sleeve 1 and the adjusting cover 5 are respectively connected with the two ends of the shaft of the central hole 6; the shifting sleeve 1 is provided with a sliding middle hole 7 which is through along the axial direction of the shifting sleeve, and the sliding middle hole 7 is communicated with the central hole 6; the thimble 2 comprises a front section 8 which is slidably matched with the sliding central hole 7 and a collar 9 which is formed by expanding outwards along the radial direction from the rear end of the front section 8, and the front end of the thimble 2 is arranged to be conical; the spring 4 is elastically supported between the thimble 2 and the adjusting cover 5, and can elastically push out the thimble 2 to enable a shaft ring 9 to be pressed on the rear end surface of the shifting sleeve 1.
When the tool is stirred in the gear hobbing of the shaft part in the scheme, the tool can be connected to a chuck of a gear hobbing machine, so that the ejector pin 2 of the tool is abutted against one end of the shaft part, and the positioning support of the end of the shaft part is realized. In addition, the extension length of the thimble 2 can be adjusted by adjusting the position of the adjusting cover 5 screwed into the central hole 6 in a front-back mode, so that the clamping of shaft parts with different lengths can be adapted. In this embodiment, in order to facilitate the clamping of the tool, the thimble seat 3 is provided with a flange 15 for connecting the chuck.
