Universal floating fixture

Abstract

The invention provides a universal floating fixture. The universal floating fixture comprises a bottom plate which is horizontally assembled on a machine table, wherein vertical support frames are fixedly assembled at the front end and the rear end of the bottom plate, an annular swing frame is assembled between the support frames at the front end and the rear end of the bottom plate, the swing frame is rotationally assembled with the front support frame and the rear support frame through shaft pins separately, horizontal swing plates are connected to the left end and the right end of the swing frame through connection frames, and a pneumatic chuck clamping a cylindrical shape is assembled on each swing plate; and front and rear floating gaps are designed between the front end and the rearend of the swing frame and the support frames, left and right floating gaps are designed between the left end and the right end of the swing frame and the connection frames, and inclined floating gaps are designed in the lower plates of the swing plates and the upper part of the bottom plate. The fixture is simple in structure, and low in manufacturing cost; the purpose of location for honing orhoning is achieved; and the technical effects of mechanization, automation and reliable performance can be realized.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a universal floating clamp. Background technique [0002] In the process of mechanical production, fixtures are often used to fix the workpiece to be processed. In the process of fixing, not only the clamping of the workpiece to be processed must be considered, but also the position adjustment of the workpiece should be facilitated. However, the traditional fixtures are all fixed structures. Once the workpiece is clamped, the position of the workpiece relative to the processing equipment does not change. Because the shape of the workpiece is not accurate before processing, the position of the clamped workpiece cannot be absolutely accurate. , so that the machining accuracy of the workpiece often cannot meet the required accuracy requirements. In addition, when processing workpieces, especially when performing some high-precision honing or reaming processing, people...

However, the traditional fixtures are all fixed structures. Once the workpiece is clamped, the position of the workpiece relative to the processing equipment does not change. Because the shape of the workpiece is not accurate before processing, the position of the clamped workpiece cannot be absolutely accurate. , so that the machining accuracy of the workpiece often cannot meet the required accuracy requirements

In addition, when processing workpieces, especially when performing some high-precision honing or reaming processing, people can only process by fixing the outer wall of the workpiece. The traditional processing equipment is difficult to ensure that the central hole axis of the workpiece is in line with the The axes of the processing equipment coincide, so that honing or reaming cannot accurately guarantee the accuracy of the processed hole
