Problems solved by technology

In this process, the indexing shaft will rotate together with the indexing block, thereby realizing the adjustment of the workpiece processing surface, but this indexing structure can only be adjusted at a fixed angle, that is, it can only be adjusted according to two adjacent angles. The angle between the indexing and fitting surfaces is switched. This structure makes the number of angles that can be indexed by the indexing chuck very small. Therefore, when the angles between the surfaces to be processed on the workpiece are not uniformly distributed, It is difficult to switch, resulting in narrow applicability of this indexing chuck

Embodiment Construction

[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0037] Such as figure 1 with figure 2 As shown, a non-equal hydraulic indexing chuck includes a chuck body 1, a clamping chamber 2, a deck chamber 3, an indexing deck 4, a clamping deck 5, an indexing mechanism 6, and the chuck body 1. The shape is similar to the common hydraulic chuck, which is cylindrical; the clamping cavity 2 is set on one end surface of the chuck body 1; , and communicate with the clamping cavity 2, the two clamping cavity 3 is symmetrical about the center of the chuck body 1, and the inner wall of one clamping cavity 3 close to the clamping cavity 2 is integrally provided with a surrounding positioning ring twenty one.

[0038] The indexing deck 4 and the clamping deck 5 are respectively rotatably installed in the two deck chambers 3. This is the case when working. First, put the workpiece into the clamping chamber 2 and place the w...

Abstract

The invention discloses a non-equal hydraulic index chuck, and relates to a machine tool fixture. The non-equal hydraulic index chuck is used for solving the problem that an ordinary hydraulic chuck has a small angle adjustment range. The non-equal hydraulic index chuck comprises a chuck body, a clamping cavity formed in the chuck body, at least two blocking seat cavities formed in the chuck body,an indexing blocking seat and a clamping blocking seat respectively and rotatably connected to the interiors of the two blocking seat cavities, and further comprises an indexing mechanism, wherein the indexing mechanism comprises an indexing cavity, an indexing rack and meshing teeth; the indexing cavity is formed in the chuck body; the indexing rack is arranged in the indexing cavity in a penetrating manner and moves in the depth direction of the indexing cavity; the meshing teeth are formed on a rotating shaft of the indexing blocking seat; the indexing rack is meshed with the meshing teeth; a locating component for locating the indexing blocking seat is arranged on the chuck body; the indexing mechanism driven by adopting a gear and rack system can realize the relatively fine adjustment, and has relatively large angle adjustment range, so that the hydraulic chuck can be located at multiple angles, and thus, the purpose of improving the applicability of the hydraulic chuck is achieved.

Description

technical field [0001] The invention relates to a machine tool fixture, in particular to a non-equal hydraulic indexing chuck. Background technique [0002] The indexing chuck is a kind of fixture used on CNC machine tools. It is mainly controlled by oil pressure. During the process of clamping the workpiece, it can switch the processing surface at any time according to the processing requirements to achieve fast, sensitive and accurate. Therefore, in It is widely used in the field of machining. [0003] At present, the Chinese invention whose authorized notification number is CN208117407U discloses an indexing chuck, which includes a chuck body, an indexing shaft is rotatably arranged in the chuck body, and an indexing block is arranged at the center of one end of the indexing shaft , the two sides of the indexing block are provided with a first ejector rod and a second ejector rod, and the first ejector rod and the second ejector rod are movable up and down in the chuck b...
