Abstract
The invention relates to a cylindrical thin-wall workpiece clamping tool which comprises a first female claw and a second female claw. The first female claw and the second female claw are arranged on the left and right sides or the upper and lower sides of the cylindrical thin-wall workpiece clamping tool respectively and provided with a clamping surface respectively. The cylindrical thin-wall workpiece clamping tool is characterized in that the curvature of each clamping surface is larger than that of the outer edge of a cylindrical thin-wall workpiece so that two ends of the clamping surface contact the cylindrical thin-wall workpiece and other parts keep gaps with the cylindrical thin-wall workpiece during cylindrical thin-wall workpiece clamping. Because only two ends of the clamping surfaces of the cylindrical thin-wall workpiece clamping tool provided by the invention contact the outer edge of the cylindrical thin-wall workpiece and other parts do not contact during cylindrical thin-wall workpiece clamping, the original surface stress is changed into the approximate point stress, and the shape of the longitudinal section of the cylindrical thin-wall workpiece can not become into the elliptical shape.
Description
Technical field
The present invention relates to a kind of clamping jig that is used for cylindric thin-wall workpiece.
Background technology
Regular meeting runs into the processing of some thin-walled parts in machining, particularly some columniform thin-walled parts.Usually adopt clamping jig as shown in Figure 1 for these parts; Comprise the left and right sides that lays respectively at the thin-walled parts 5 of treating clamping or first female pawl 1 and second female pawl 2 of both sides up and down; The clamping face 3 of first female pawl 1 and second female pawl 2 and the shape of clamping face 4 and thin-walled parts 5 outer rim shape fits; When first female pawl 1 and second female pawl 2 were lived thin-walled parts 5, clamping face 3 and clamping face 4 contacted with the outer edge surface of thin-walled parts 5 fully.So, thin-walled parts 5 and clamping face 3 and clamping face 4 will receive the effect of power, and the longitudinal section that has caused cylinder-shaped thin wall part 5 is toward oval development, make workpiece deformation.
Summary of the invention
The purpose of this invention is to provide a kind of on-deformable clamping jig of columniform thin-walled parts that makes.
In order to achieve the above object; Technical scheme of the present invention has provided a kind of clamping jig of cylindric thin-wall workpiece; Comprise and be positioned at the cylindric thin-wall workpiece left and right sides or first female pawl and second female pawl of both sides up and down; First female pawl and second female pawl have a clamping face respectively, it is characterized in that: the radian of this clamping face is greater than the radian of cylindric thin-wall workpiece outer rim, when making clamping; The two ends of clamping face contact with cylindric thin-wall workpiece, leave the gap between other parts and the cylindric thin-wall workpiece.
The clamping jig of a kind of cylindric thin-wall workpiece provided by the invention is because when clamping; Clamping face has only two ends to contact with cylindric thin-wall workpiece outer rim; And other parts do not contact; Therefore, stressed to have changed approximate point into stressed by original face, and the longitudinal section of cylindric like this thin-wall workpiece just can not developed to ellipse.
Description of drawings
Fig. 1 is original tool sketch map;
Fig. 2 is the clamping jig sketch map of a kind of cylindric thin-wall workpiece provided by the invention.
The specific embodiment
For making the present invention more obviously understandable, now with preferred embodiment, and conjunction with figs. elaborates as follows.
As shown in Figure 2; The clamping jig of a kind of cylindric thin-wall workpiece provided by the invention; Comprise being positioned at cylindric thin-wall workpiece 5 left and right sides or first female pawl 1 and second female pawl 2 of both sides up and down that in the present embodiment, first female pawl 1 and second female pawl 2 lay respectively at both sides up and down.First female pawl 1 and second female pawl 2 have one the 3rd clamping face 6 and the 4th clamping face 7 respectively; The radian of the 3rd clamping face 6 and the 4th clamping face 7 is greater than the radian of cylindric thin-wall workpiece 5 outer rims; When making clamping; The two ends of the 3rd clamping face 6 and the 4th clamping face 7 contact with cylindric thin-wall workpiece 5, leave the gap between other parts and the cylindric thin-wall workpiece 5.
Use; First female pawl 1 and second female pawl 2 respectively from the top and the below cylindric thin-wall workpiece 5 is clamped; Because the 3rd clamping face 6 and the 4th clamping face 7 have only two ends to contact with the outer rim of cylindric thin-wall workpiece 5, therefore, can not cause the longitudinal section of cylindric thin-wall workpiece 5 to become ellipse.
