A cross shaft fixing fixture

Abstract

The invention discloses a cross shaft fixing fixture, Including bottom plate, A first side pillar and a second side pillar are arranged on the bottom plate, and the bottom ends of the first side pillar and the second side pillar are fixedly connected to both sides of the bottom end surface of the bottom plate, A lateral fix plate is arranged between that first lateral column and the second lateralcolumn, a threaded hole is arrange in the middle position of the lateral fixing plate, and the threaded hole is internally threaded to connect the central squeeze threaded column, and one end of thecentral squeeze threaded column is in contact with the surface of the central shaft of the cross shaft. As that parallel top plate is arrange on the bottom plate, and an extrusion plate controlled bya hydraulic cylinder is arranged at the bottom end of the top plate, During use, two groups of sub-shafts arranged on the vertical horizontal line of the cross shaft are fixed by using an extrusion plate, so as to be convenient for fixing the cross shafts according to different types of cross shafts, and the central shaft of the cross shaft is fixed by using a central extrusion screw column and apresser, so as to be convenient for fixing the central position of the cross shaft, so as to facilitate machining of the four groups of sub-shafts.

Description

technical field [0001] The invention relates to the technical field of cross shaft production and processing, in particular to a cross shaft fixing fixture. Background technique [0002] The cross shaft is also called a ten-byte, that is, a universal joint. The cross shaft includes the base body and the shaft body distributed on the base body in the shape of a "ten". If one of the cross shafts is placed along the horizontal direction, two shaft bodies must be in the horizontal direction. These two shaft bodies are called The cross axis is the horizontal axis; the other two axes are in the vertical direction, and these two axes are called the cross axis vertical axis. [0003] When processing the cross shaft, it needs to be positioned with a fixture. The existing fixed fixture mainly realizes the positioning of the cross shaft by setting four V-shaped grooves symmetrically along the cross-shaped direction on the clamp body, but the cross shaft will be embedded In the cross-...

Problems solved by technology

[0003] When processing the cross shaft, it needs to be positioned with a fixture. The existing fixed fixture mainly realizes the positioning of the cross shaft by setting four V-shaped grooves symmetrically along the cross-shaped direction on the clamp body, but the cross shaft will be embedded In the cross-shaped groove, the exposed part of the cross shaft is less, the entire back of the cross shaft will be covered, and a large part of the shaft body will also be covered, which is inconvenient when processing the back position of the cross shaft, thus increasing The efficiency of the process is reduced, and the flexibility of the existing fixture is poor, so we improve this and propose a cross-axis fixture
