Problems solved by technology

Since the vertical axis is not clamped, the workpiece will bounce during processing, which will affect the processing quality
In addition, when the three-jaw chuck is clamped, it is difficult to ensure the coaxiality of the cylindrical shafts on both sides (that is, the two cylindrical shafts in the vertical direction). It is troublesome to clamp and correct parts, and the processing efficiency is not high.
Therefore, there are problems in the prior art that the cross-axis workpiece cannot be clamped and the positioning is inaccurate

Abstract

The invention discloses a clamp for turning a universal joint. The clamp comprises a first locating mechanism used for locating a universal joint work-piece (1) in the vertical shaft direction of the universal joint work-piece (1), and a second locating mechanism used for locating the universal joint work-piece (1) in the horizontal shaft direction of the universal joint work-piece (1). The first locating mechanism and the second locating mechanism can locate the universal joint work-piece in the vertical shaft direction and the horizontal shaft direction at the same time, and therefore the universal joint work-piece can be clamped in a centring mode, firm locating in the turning process is guaranteed, and the coaxiality of two cylindrical shafts on the two sides of a machined cylindrical shaft is guaranteed. The clamp can clamp and locate the universal joint work-piece accurately.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a fixture for turning a cross shaft. Background technique [0002] For the turning of the cross shaft, a typical part in the automobile differential, the conventional method is to use the three-jaw chuck that comes with the ordinary lathe. When the three-jaw chuck is used for clamping, only the front end cylinder of the cross-axis workpiece can be clamped. During initial processing, the tip of the tool is easily damaged by the vertical axis. Since the vertical axis is not clamped, the workpiece will bounce during processing, which will affect the processing quality. In addition, when the three-jaw chuck is clamped, it is difficult to ensure the coaxiality of the cylindrical shafts on both sides (that is, the two cylindrical shafts in the vertical direction). It is troublesome to clamp and correct parts, and the processing efficiency is not high. Therefore, there are problem...
