Spline housing rapid clamping connector

Abstract

The invention relates to a spline housing rapid clamping connector. The spline housing rapid clamping connector comprises a grinding machine connection disc, an expansion core shaft, a pull rod, an expansion housing and a wedge block; the expansion core shaft is coaxially mounted on the front end of the grinding machine connection disc, the pull rod is coaxially arranged in the expansion core shaft in a penetrating manner, the rear end of the pull rod is connected with the grinding machine connection disc, the wedge block is arranged on the pull rod in a penetrating manner, the wedge block isin slope connection with the inner wall of the pull rod, the front end of the pull rod extends to the outer side of the front end of the expansion core shaft, a blocking disc is arranged on the frontend of the pull rod, the expansion housing is coaxially mounted on the outer side of the expansion core shaft, the expansion bushing is located between an annular positioning boss and the pull rod blocking disc, and the expansion bushing and the expansion core shaft are in slope contact. The spline housing rapid clamping connector is reasonable in structure, convenient to use, and high in practicability. The connector can reduce clamping difficulty, work efficiency is improved, machining precision is improved, and the rejection rate is reduced. In addition, the connector is wide in applicationrange and is suitable for machining of spline housings of two specifications.

Description

technical field [0001] The invention relates to a clamping tool in the technical field of production and processing of spline sleeves, in particular to a fast clamping connector for spline sleeves. Background technique [0002] Such as Figure 4 and Figure 5 As shown, there are two types of spline sleeves. The spline sleeve needs to be finely ground the outer diameter of the small end. At present, there is no special fixture for clamping the workpiece. The staff can only use simple tools such as a pressing plate to locate and lock. However, since this processing belongs to finishing processing, after simple fixing , due to the low accuracy of the clamping, the machining accuracy of the workpiece is low, and rework is often required, which increases the working time, and requires high technical level and experience of the staff. Increased costs. Contents of the invention [0003] The purpose of the present invention is to make up for the deficiencies of the prior art, a...
