Juggle type precise flat tong for machine tool with large processing table

Abstract

The invention relates to building block system precision flat-nose pliers for large processing table facet machine. The building block system precision flat-nose pliers is essentially to solve the problems of low machine work efficiency of the machine, noticeable partial wear and tear on operation parts of the machine, and poor processing precision of the work pieces with poor rigidity existed in the prior art. The technical proposal is as follows: a group of flat-nose pliers are installed on the work table facet of a machine, which is characterized in that a group of flat-nose pliers comprise three or more independent flat-nose pliers arranged in parallel; each independent flat-nose plier comprises a block, a fixed jaw fixed on the block, two or more movable jaws matched on the block guide rail in a sliding way, and a quick travel mechanism installed on the block; both outer side faces of the block guide rail are equipped with teeth rows; the quick travel mechanism comprises a nut seat matched with the block guide rail in a sliding way, a thrust screw thread matched with the nut seat by screw, and an expansion device arranged on both sides of the nut seat and matched with the teeth rows on both outer side faces of the block guide rail; and a thrust end of the thrust screw is matched with one movable jaw.

Description

technical field [0001] The invention belongs to working parts of machine tools, and specifically refers to a building-block type precision flat-nose pliers suitable for use on machine tools with relatively large processing worktables such as machining centers, gantry milling machines, and gantry planers. Background technique [0002] Generally used machining centers, gantry milling machines, gantry planers and other machine tools with relatively large processing worktables generally have one to two vises installed on the worktables to fix the workpiece to be processed. The traditional structure of the flat nose pliers is composed of a clamp base, a fixed jaw fixed on the clamp base, a movable jaw slidingly fitted on the clamp base, a screw rod fitted on the clamp base and a nut installed on the movable jaw. Wherein the nut and the screw rod are threadedly matched. [0003] The applicant once proposed a precision vise used on a machine tool that can quickly move the movable ...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the fact that the flat-nose pliers structure used on the existing machine tools with relatively large processing worktables causes the existence of machine tools to be processed by one piece, the work efficiency is not high, and it is easy to cause obvious local wear on the moving parts of the machine tool and shorten the service life of the machine tool. The workpiece with poor rigidity has defects such as low machining accuracy. The purpose of this invention is to provide an improved building block type precision vise for large machining table machine tools, which can overcome the defects of the prior art.
