Installation structure for shaver and main shaft of gear shaving machine

Abstract

The invention discloses an installation structure for a shaver and a main shaft of a gear shaving machine. The shaver is sleeved on the main shaft through an expanding sleeve; a return spring is arranged on the right part of an inner bore of a taper sleeve, the return spring and the taper sleeve are both sleeved on the main shaft in a loose manner, the left end of the return spring and a limit step on the body of the main shaft are in butted connection, and the right end of the return spring and an annular step on the right end of the inner bore of the taper sleeve are in butted connection; the right end part of the main shaft is connected with a locking mechanism which comprises a pressure pad and a pressure spring, and the pressure pad is sleeved on the right part of the taper sleeve in a loose manner; and a pressure sleeve and a connecting plate are arranged on the right side of the pressure pad from left to right in sequence, and the pressure pad, the pressure sleeve and the connecting plate are connected together fixedly. According to the invention, the expanding and tightening property of the expanding sleeve is mainly utilized, so that not only are the detachment and installation of the shaver facilitated, but also a gap between the shaver and the main shaft is eliminated reliably, so that the machining precision and the durability of the shaver are guaranteed at the same time, the defect of the traditional structure is overcome favorably, the problem which is not solved for a long time is solved by means of small alternation, and the installation structure has very good technical and economic values and is suitable for wide popularization and application.

Description

technical field [0001] The invention belongs to the field of gear shaving machines, and in particular relates to a mounting mechanism for a razor and a main shaft of a gear shaving machine. Background technique [0002] like figure 1 As shown, the traditional gear shaving machine razor and main shaft installation structure includes a razor 1, a key 2 and a main shaft 3. The razor 1 is set on the right part of the main shaft 3. Key 2 to transmit torque. Moreover, the main shaft 3 on the left side of the razor 1 is fixedly sleeved with a positioning sleeve 4, and the main shaft 3 on the right side of the razor 1 is connected with a locking mechanism, so that the razor 1 is locked on the main shaft 3 through the positioning sleeve 4 and the locking mechanism. . [0003] The gap between the above-mentioned razor 1 and the main shaft 3 can neither be too large nor too small. If it is too large, it will affect the coaxiality of the razor 1 and the main shaft 3, thereby serious...

AI Technical Summary

Problems solved by technology

If it is too large, it will affect the coaxiality of the razor 1 and the main shaft 3, thereby seriously affecting the machining accuracy; if it is too small, it will be inconvenient to disassemble and assemble the razor 1

[0004] In addition, since the razor 1 and the main shaft 3 are clearance fit, there will always be a large or small gap between them, which will cause the razor 1 to vibrate to a certain extent during the processing, and then cause the razor 1 edge The loss of the razor is relatively large, which will affect the durability of the razor 1
