Abstract
The utility model discloses a fixture for grinding inner holes of thin-wall pipes. The fixture is composed of a chuck and chuck jaws, the chuck jaws are used for clamping workpiece clamping devices which fix thin-wall pipes to be machined, and the clamping devices clamp and fix the upper surfaces and the lower surfaces of the thin-wall pipes to be machined. The fixture has the advantages that the chuck jaws do not make contact with workpieces to be machined, deformation of the workpieces due to the fact that the chuck jaws are in linear contact with the workpieces and the workpieces are partially stressed is avoided, and the fixture is simple in structure and convenient to use.
Description
Technical field
The utility model belongs to machining equipment technical field, especially relates to a kind of fixture of grinding thin-wall pipe endoporus.
Background technology
Existing common workpiece inner hole grinding tool device, is generally to adopt the direct clamping workpiece cylindrical of chuck jaw, and chuck jaw and workpiece are local pressures like this, usually because the outer wall of workpiece to be processed is thinner, easily cause the thin workpiece deformation of wall in process.
Summary of the invention
The purpose of this utility model is to improve the deficiency of prior art and provides a kind of chuck jaw not contact workpiece to be processed, avoids contacting with workpiece alignment because of chuck jaw the fitting device of distortion that local pressure produces, grinding thin-wall pipe endoporus simple in structure, easy to use.
The purpose of this utility model is to realize like this, a kind of fixture of grinding thin-wall pipe endoporus, by chuck and chuck jaw, formed, be characterized in that chuck jaw blocks fixing thin-wall pipe Workpiece clamping device to be processed, the be fixedly clamped upper and lower surface of thin-wall pipe workpiece wall to be processed of this clamping apparatus.
In order further to realize the purpose of this utility model, can be that described clamping apparatus comprises retainer ring, set bolt, gland, gland is connected with retainer ring by set bolt, and thin-wall pipe workpiece to be processed is arranged between gland and retainer ring, and gland center has machining hole.
In order further to realize the purpose of this utility model, can be that the diameter of described machining hole is between the inside and outside footpath of thin-wall pipe workpiece to be processed.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model adopts chuck jaw to block fixing thin-wall pipe Workpiece clamping device to be processed, the be fixedly clamped upper and lower surface of thin-wall pipe workpiece wall to be processed of this clamping apparatus, chuck jaw does not directly block workpiece like this, while avoiding the line contact because of chuck jaw, workpiece produces distortion, and clamping apparatus clamping is the upper and lower surface of thin-wall pipe workpiece wall to be processed, make the axially loaded of processing thin-walled pipe fitting workpiece, holding capacity strengthens greatly, has avoided workpiece because clamping stress deformation; Clamping apparatus is that gland is connected with retainer ring by set bolt, thin-wall pipe workpiece to be processed is arranged between gland and retainer ring, gland center has machining hole, by set bolt, be connected and fixed ring, tighten set bolt and can clamp thin-wall pipe workpiece to be processed, this apparatus structure is simple and practical, production efficiency is high, safe and reliable, labour intensity is low, has fully solved the problem that thin-wall part processing endoporus is out of shape due to clamping.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is another kind of structural representation of the present utility model.
The specific embodiment
A fixture for grinding thin-wall pipe endoporus, with reference to Fig. 1, is comprised of chuck 5 and chuck jaw 6, is that chuck jaw 6 blocks fixing thin-wall pipe workpiece 4 clamping apparatus 8 to be processed, the be fixedly clamped upper and lower surface of thin-wall pipe workpiece 4 walls to be processed of this clamping apparatus 8.
With reference to Fig. 2, described clamping apparatus 8 comprises retainer ring 1, set bolt 2 and gland 3, gland 3 is connected with retainer ring 1 by set bolt 2, thin-wall pipe workpiece 4 to be processed is arranged on 1 of gland 3 and retainer ring, gland 3 centers have machining hole 7, and the diameter of described machining hole 7 is between the inside and outside footpath of thin-wall pipe workpiece 4 to be processed.
