Problems solved by technology

Most of the fixtures used in domestic gear shaping machines are three-jaw chucks or mechanical manual clamping. Three-jaw chucks are more versatile, but for ring gear parts with thinner walls, the clamping process is variable, and the parts processing The accuracy is poor; manual fixtures have poor clamping stability and low efficiency, and are not suitable for mass production

Embodiment Construction

[0022] The present invention is described in further detail below in conjunction with accompanying drawing:

[0023] see Figure 1 to Figure 6 , the present invention includes a base 6, and a body 8 installed on the base 6, the inner side of the body 8 is sequentially installed with a connection plate 5, an expansion sleeve 2 and a support 3; the base 6 is fixedly connected with the machine tool workbench. The middle part of the connection disc 5 is equipped with a pull rod 4, and the pull rod 4 passes through the connection disc 5 downwards and is screwed into the connection rod 7 installed on the sliding piston of the machine tool. The pull rod 4 is fixed on the connection plate 5 by screws. The support 3 is a petal-shaped tooth structure, and is matched with the upper chute of the body 8 to prevent the accumulation of iron filings from affecting the processing.

[0024] When in use, fasten the connecting rod 7 to the sliding piston of the machine tool first, then connect ...

Abstract

The invention discloses a large-ring-gear externally-expanded type efficient gear shaping clamp which comprises a base and a body arranged on the base. A connection disk, an expansion sleeve and a support are sequentially arranged on the inner side of the body from bottom to top. The base is fixedly connected with a machine tool table. Compared with a three-jaw chuck and manual clamping, the large-ring-gear externally-expanded type efficient gear shaping clamp is constant in clamping force, the clamping process is stable and reliable, and parts are not prone to deforming; the large-ring-gear externally-expanded type efficient gear shaping clamp is suitable for gear shaping machines of various specifications by replacing the base and a connection rod, and the large-ring-gear externally-expanded type efficient gear shaping clamp is suitable for parts of different size series by replacing the expansion sleeve and the support. The support can be designed of a petal type toothed structure and is paired with a chute arranged on the body, the chip removing speed is increased, and accumulated scrap iron is effectively prevented from affecting machining. The clamp is relatively simple in whole structure and convenient to manufacture, and an adjustment space is reserved for insufficient manufacturing and assembling precision. The clamp can be arranged as a whole or parts of the clamp are sequentially arranged, and the parts can be conveniently detected and replaced.

Description

【Technical field】 [0001] The invention relates to a high-efficiency gear shaping fixture with a large tooth ring expanding outward. 【Background technique】 [0002] Industrial reducers and automatic transmissions have a planetary gear structure, and the inner ring gear of the large ring gear meshes with the planetary gear, requiring high precision. The inner ring gear is mostly machined by gear shaping, and its precision is mainly affected by tools, machine tools and gear shaping fixtures. Most of the fixtures used in domestic gear shaping machines are three-jaw chucks or mechanical manual clamping. The three-jaw chucks are more versatile, but for ring gear parts with thinner walls, the clamping process is variable, and the parts processing The accuracy is poor; manual fixtures have poor clamping stability and low efficiency, and are not suitable for mass production. In addition, there are many brands and specifications of domestic gear shaping machines, and their connectio...
