Abstract

A clamping device for processing the excircle of thin wall part is provided, comprising a jig body, a pressing plate, on which is provided a compression screw, which is connected onto the jig body, on which are provided an end face and a cylindrical surface for workpiece positioning. The clamping device in the utility model uses the part inner circle and the end face to perform the positioning, the clamping part is on the workpiece end face, the part undertakes axial force instead of radial force, therefore, the workpiece will not be deformed during the clamping process, with a high precision of processing. The clamping device has advantages of eliminating part clamping position, greatly improving material utilization rate, reducing manufacture cost by more than one third, and also has advantages of simple structure, easy manufacture, and high production efficiency.

Description

A kind of clamping device of processing thin-walled part cylindrical
Technical field
The utility model relates to a kind of machinery processing apparatus, particularly the clamping device of processing thin-walled part cylindrical on lathe.
Background technology
For a long time, the processing of the cylindrical of thin-walled parts is a difficult problem always, because the part wall is thin yielding, is difficult for clamping, and not noting slightly will be because of distortion causes form and position tolerance overproof, the percent defective height.For fear of causing product rejection because of distortion, it usually is the retaining part that increases part, after machining, excised again, though this method is comparatively effective, but increased material consumption, and the part dimension difference, the amount of the retaining part that is increased is also different, the cost of some heavy parts may increase more than 1/3, has improved manufacturing cost greatly.
The utility model content
The utility model aims to provide a kind of clamping device of processing thin-walled part cylindrical, can effectively avoid the clamping distortion, improves product percent of pass, reduces production costs.Simple in structure, easy to use.
A kind of clamping device of processing thin-walled part cylindrical comprises clamp body, and pressing plate has housing screw on the pressing plate, and housing screw is connected on the clamp body, has part that the end face and the external cylindrical surface of location are installed on the clamp body.
Further, on the described clamp body installation screw is arranged.
The utility model is bowlder outside processing thin-walled part, with circle and end face location in the part, clamps the position on workpiece end face, and part only is subjected to axial force not to be subjected to radial load, so workpiece can not be out of shape the machining accuracy height in clamping process.Save the retaining part of part, improved stock utilization greatly, reduced manufacturing cost more than 1/3.Simple in structure, easily manufactured, the production efficiency height.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: the 1-clamp body, the 11-end face, the 12-external cylindrical surface, 13-installs screw, 2-pressing plate, 3-housing screw, 4-part.
The specific embodiment
As shown in Figure 1, the clamping device of processing thin-walled part cylindrical, comprise clamp body 1, pressing plate 2, housing screw 3 is arranged on the pressing plate 2, and housing screw 3 is connected on the clamp body 1, and the head inner face of housing screw 3 is pressed on the pressing plate 2, tighten screw and just can clamp part 4 by pressing plate 2, also available bolt, nut replace housing screw.End face 11 and external cylindrical surface 12 that the location is installed as part to be processed are arranged on the clamp body 1.Further, the screw 13 of installation is arranged on the clamp body 1, be used for being fixed on the lathe.
During use, earlier the utility model is installed on the lathe, fixing behind the centering.Available screw is fixed on the lathe ring flange, also can be fixed on the lathe three-jaw.Part 4 to be processed contacts location with the location end face 11 of clamp body 1 with location external cylindrical surface 12 with inner cylinder face with end face, tightens housing screw 3, just can clamp part, 4 of parts are subjected to axial force during clamping, be not subjected to radial load, avoided distortion, created condition for improving machining accuracy.The part that interior step surface is arranged, the place compresses at interior step surface, can finish to foreign round the processing with end face.
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
