Description

Thin cylinder workpiece alignment cutting clamping device

Technical field

The utility model belongs to Machining Technology field, relates to a kind of clamping device, is specifically related to a kind of line cutting processing clamping device for thin cylinder workpiece.

Background technology

Line discharge cutting machine was invented in the Soviet Union in nineteen sixty, because line cutting processing is applicable to the processing of high rigidity, difficult-to-machine material and complex-shaped surface mould, in manufacturing industry, particularly in Mould Machining, played extremely important effect.Using wire cutting machine tool to add man-hour to thin cylinder, need to use clamping device that thin cylinder is stepped up, at that time because thin cylinder exists that wall is thin, the feature such as poor rigidity and weak strength, so very easily produce distortion in its clamping process, thereby affected the required precision of its dimensional accuracy and form and position tolerance.

Utility model content

The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, a kind of thin cylinder workpiece alignment cutting clamping device is provided, it is reasonable in design, simple in structure, and machining accuracy is high, workpiece easy accessibility, labour intensity is low, and production efficiency is high, fixture long service life, production cost is low, is convenient to promote the use of.

For achieving the above object, the technical solution adopted in the utility model is: a kind of thin cylinder workpiece alignment cutting clamping device, comprise the U-shaped base for being fixedly connected with wire electrode cutting bench, it is characterized in that: also comprise L shaped slide bar bearing for supporting slider, be used to the L shaped positioning baffle of location, workpiece to be processed end and for coordinate the V-arrangement block that compresses workpiece to be processed with hold-down head; Described U-shaped base one end upside is fixedly installed described L shaped slide bar bearing, slide and be provided with slide bar in described L shaped slide bar bearing middle part, described slide bar one end is fixedly installed handle, the described slide bar other end is fixedly installed described hold-down head, between described hold-down head and described L shaped slide bar bearing, be provided with holddown spring, described U-shaped base other end upside is fixedly installed described V-arrangement block by bearing, and described U-shaped base side wall upside is fixedly installed described L shaped positioning baffle.

Above-mentioned thin cylinder workpiece alignment cutting clamping device, is characterized in that: described L shaped slide bar bearing is bolted and is arranged on described U-shaped base, and described L shaped positioning baffle is fixedly installed on described U-shaped base by sunk screw.

Above-mentioned thin cylinder workpiece alignment cutting clamping device, is characterized in that: described hold-down head is V-arrangement hold-down head.

The utility model compared with prior art has the following advantages:

(1) this thin cylinder workpiece alignment cutting is very reasonable with clamping device design, simple and compact for structure, under the effect of holddown spring, hold-down head and V-arrangement block are used in conjunction with workpiece to be processed are clamped, clamp effective, L shaped positioning baffle can accurately be located workpiece to be processed end, and machining accuracy is able to effective guarantee.

(2) the workpiece easy accessibility of clamping device for this thin cylinder workpiece alignment cutting, operating personnel only need pull slide bar can unclamp or clamp workpiece to be processed by handle, thereby labor strength is low, and production efficiency is high.

(3) in use there is not rigid shock with clamping device in this thin cylinder workpiece alignment cutting, thereby its long service life.

(4) this thin cylinder workpiece alignment cutting is all convenient to produce, buy with a lot of parts of clamping device very much, thereby its production cost is very low, is convenient to batch production, promotes the use of.

Below by drawings and Examples, the utility model is described in further detail.
