Square tool table pushing, positioning and clamping mechanism for lathe

Abstract

The invention relates to a square tool table pushing, positioning and clamping mechanism for a lathe. The square tool table pushing, positioning and clamping mechanism comprises a framework. Side cylinders and an intermediate cylinder which are connected with a hydraulic control device are vertically arranged on the framework. Side pressing plates are rotationally connected to the upper ends of piston rods matched with the side cylinders. An intermediate pressing plate is rotationally connected at the upper end of an intermediate piston rod matched with the intermediate cylinder. Support blocks for supporting a square tool table are fixed on two sides of the intermediate portion of the two adjacent piston rods on the framework, and a rest table is fixed on the left side of the same. A slider is arranged on the framework, and an insert for being inserted into an inner hole of the square tool table is fixed above the slider. A left auxiliary support is arranged at the left end of the framework, and a right auxiliary support is arranged at the right end. A pushing mechanism pushing the square tool table to the rest table is arranged on the framework. The square tool table pushing, positioning and clamping mechanism is simple in integral structure, flexible and reliable to act, small in occupation space, low in manufacturing cost, firm to clamp and good in stability.

Description

technical field [0001] The invention relates to a clamping mechanism, in particular to a clamping mechanism for positioning and pushing a square tool table for a lathe. Background technique [0002] There are grooves around the outside of the square tool table assembled on the lathe. When processing the groove, the square tool table needs to be clamped. Usually, the workpiece clamping is completed by the clamping cylinder and the auxiliary pushing cylinder. This form of fixture occupies the space cost It is tall and tall, and the manual combined fixture consisting of a pressure plate and bolts used in manual clamping is fixed on the ordinary machine tool workbench through a T-shaped slot when in use, and the workpiece is manually clamped after the workpiece is installed, and the clamping force and clamping position are manually controlled. , strong randomness, resulting in low machining accuracy of the workpiece. Neither of the above two methods can achieve the purpose of c...

[0002] There are grooves around the outside of the square tool table assembled on the lathe. When processing the groove, the square tool table needs to be clamped. Usually, the workpiece clamping is completed by the clamping cylinder and the auxiliary pushing cylinder. This form of fixture occupies the space cost It is tall and high, and the manual combined fixture composed of the pressure plate and bolts used in manual clamping is fixed on the ordinary machine tool workbench through the T-shaped slot when in use, and the workpiece is manually clamped after the workpiece is installed, and the clamping force and clamping position are manually controlled. , strong randomness, resulting in low workpiece machining accuracy

Neither of the above two methods can achieve the purpose of saving cost and completing workpiece clamping well.
