Pneumatic deputy knife rest

Abstract

The invention discloses a pneumatic deputy knife rest. The pneumatic deputy knife rest comprises a baseboard, a guide rail and a sliding block, wherein the guide rail is arranged on the baseboard, and the sliding block is slidably matched with the guide rail; a deputy knife rest body is fixedly arranged on the sliding block, one end of the guide rail is provided with a angle iron, an air cylinder is fixedly installed on the angle iron, a piston rod of the air cylinder is fixedly connected with a connecting block, the connecting block is fixedly connected with the deputy knife rest body, and the other end of the guide rail is provided with a limit stop block matched with the sliding block. The pneumatic deputy knife rest has the advantages that the structure is simple and reasonable, the operation is convenient, the installation is convenient and fast, the service life of a knife is effectively improved, the knife aligning time is reduced, the working efficiency is higher, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to the technical field of lathe auxiliary tool holders, in particular to a pneumatic auxiliary tool holder. Background technique [0002] Auxiliary tool post is a relatively common lathe auxiliary device, which is widely used in the field of machinery manufacturing and is well known and common to the public. The workpiece requires a variety of tools to work together. For example, during the clamping process of the plunger sleeve, an outer turning tool, an end turning tool, an inner hole rough boring tool, an inner hole fine boring tool, a grooving tool and a triangular groove tool are required. to cooperate in work. When the above six cutting tools are installed, the grooving knife and the triangular grooving knife are welded and installed on the same tool holder. Since the CNC lathe turret can usually only install four tools, it is necessary to directly install the auxiliary tool holder on the workbench. Install and fix the inn...

Problems solved by technology

However, the common problem of directly installing the auxiliary tool holder on the workbench is that: when the auxiliary tool holder is too close to the turret, it will interfere with the fine boring tool during the rotary cutting of the plunger sleeve; Will exceed the radial movement stroke of the table

Therefore, the position accuracy of the direct installation of the auxiliary tool post on the workbench is very high, and the accuracy is difficult to control during actual operation, and the installation is difficult. Therefore, in actual operation, only the rough boring tool and the fine boring tool can only be installed by welding. The method on the same boring tool bar, but in this way, it will cause the defects of uneven wear of the rough boring tool and the fine boring tool during use, difficulty in changing the tool, and the number of tool setting has also increased, resulting in auxiliary tools during the processing. If the time is too long, it not only reduces the work efficiency, but also increases the labor intensity of the workers
