Automatic tool clamp of machine tool shaft pipe fittings

Abstract

The invention discloses an automatic tooling fixture for machine tool shaft pipe fittings, which includes a machine tool, a concave support table, a tailstock and a second guide rail. The connecting plate is fixedly connected, and the right side of the chuck body is equipped with a claw with a clamping nail inside, the bottom end of the concave support table is installed with a hydraulic rod that is slidingly connected with the first guide rail, and the upper end of the tailstock The connecting rod and the inner ring of the bearing are fixedly connected, the slider inside the second guide rail is fixedly connected with one end of the piston rod through a fixed block, and the piston is fixed on the inner wall of the chuck body through a positioning block A sealing ring is installed between the cylinder blocks. The invention adopts the hydraulic cylinder to drive the claws to clamp the shaft pipe fittings, so that the positioning and clamping process is quick, and at the same time, a chuck is also arranged on the tailstock, which avoids the need to process the inner hole on the parts when clamping the shaft pipe fittings, saving working hours.

Description

technical field [0001] The invention relates to the technical field of tooling and fixture equipment, in particular to an automatic tooling and fixture for shaft and pipe fittings of machine tools. Background technique [0002] In today's era of rapid development, the processing of products is inseparable from the processing of machine tools. Using machine tools to process products can not only save labor time, improve work efficiency, but also reduce the labor intensity of workers, but machine tools have relatively high precision requirements for product processing. Strictly, the performance of a machine tool fixture will greatly affect the processing performance of the machine tool. When processing shaft pipe fittings, the traditional method is to use chuck fixtures and cone plug fixtures. Although manual clamping chuck fixtures can be Reduce the production cost of the machine tool, but this kind of fixture is time-consuming to clamp. The tailstock adopts a cone-type fixtu...

[0002] In today's era of rapid development, the processing of products is inseparable from the processing of machine tools. Using machine tools to process products can not only save labor time, improve work efficiency, but also reduce the labor intensity of workers, but machine tools have relatively high precision requirements for product processing. Strictly, the performance of a machine tool fixture will greatly affect the processing performance of the machine tool. When processing shaft pipe fittings, the traditional method is to use chuck fixtures and cone plug fixtures. Although manual clamping chuck fixtures can be Reduce the production cost of the machine tool, but this kind of fixture is time-consuming to clamp. The tailstock adopts a cone-type fixture. Due to the lack of rigidity of this kind of fixture, it is easy to vibrate during the machining process, which makes it deviate from the center hole and cannot be processed with a large amount of cutting. Production Efficiency cannot be improved
