Abstract
The utility model discloses a tool clamp for machining the end surface of conical drum-like parts. The tool clamp comprises a mandrel; a wedge plate I, an elastic sleeve structure tension mechanism formed by a pressure spring and a tension sleeve, a wedge plate II and a locking nut are sequentially arranged on the mandrel; the wedge plate I and the wedge plate II are axially and radially positioned by step shafts arranged on the mandrel; a thin soft material wraps the outer part of the tension sleeve; the locking nut realizes the axial motion by a threaded section arranged at the tail end of the mandrel, so the tension mechanism is loosened and tensioned. The tool clamp for machining the end surface of the conical drum-like parts has the characteristics of simple structure, accuracy in location and fast and convenient operation, and solves the problems that the position precision of a part is not easily ensured in the machining process and the machining efficiency is low.
Description
Technical field
The utility model belongs to technical field of tooling clamps, is specifically related to the frock clamp for boring the processing of tube kind part end face.
Background technology
Epoxy resin conic tube class part General Requirements part both ends of the surface are equipped with threaded insert, and both ends of the surface should be parallel, and end face should be vertical with endoporus.For meeting above requirement, part both ends of the surface should be carried out turning processing, main conventional method, the dedicated tool of relying on processed at present, its processing method is as follows: first part one end is fixed on special connecting plate by inserts screw, special connecting plate is clamped on the scroll chuck of lathe main shaft end, and the other end is unsettled; Add and drive part to rotate by main shaft man-hour, middle carriage band cutter completes the processing of an end face of part do radial motion, and then part tune, processes other end and guarantee length dimension according to said method.The subject matter that the method exists is: on the one hand part is vacant state, adds man-hour part and is prone to the phenomenons such as shake line, inclination, and surface quality of workpieces is poor, and the perpendicularity of the both ends of the surface depth of parallelism and end face and axis is poor, and part position precision is difficult for assurance; Because part is wanted clamping twice, working (machining) efficiency is low on the other hand.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of cone tube kind part end face machining tool fixture, be difficult for guaranteeing and the low problem of working (machining) efficiency to solve part position precision in processing parts process, can effectively guarantee the machining accuracy of part, and improve working (machining) efficiency.
For achieving the above object, the utility model adopts following technical scheme:
A kind of cone tube kind part end face machining tool fixture, it is characterized in that: comprise a mandrel, on described mandrel, be disposed with wedge one, tension mechanism, wedge two, locking nut, described tension mechanism comprises and is assemblied in the stage clip between wedge one, wedge two and is arranged at the expansion sleeve outside stage clip, and the thread segment that described locking nut arranges by mandrel end is realized axially-movable and made tension mechanism tensioner and loosening.
Preferably, on described mandrel, be provided with Step Shaft, described wedge one, wedge two are undertaken axially and radial location by Step Shaft.
Preferably, described expansion sleeve outside is wound with deformable sheet materials.
By above technical scheme, the utility model efficiently solve in conic tube class part process due to part is unsettled and multiple clamping add man-hour part be prone to that shake line, inclination etc. cause that surface quality of workpieces is poor, the problem that perpendicularity is poor, part position precision is difficult for assurance of the both ends of the surface depth of parallelism and end face and axis, guarantee the quality of part, and the clamping of part in minimizing process, improve working (machining) efficiency, have simple in structure, accurate positioning, swift to operate, feature easily.
Accompanying drawing explanation
Accompanying drawing one is the utility model cross-sectional view.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model feature and operation principle are elaborated.
As shown in Figure 1, a kind of cone tube kind part end face machining tool fixture, include mandrel 1, the elastic sleeve structure tension mechanism, wedge 22, the locking nut 5 that on described mandrel 1, are disposed with wedge 1, are formed by stage clip 6 and expansion sleeve 3, wherein said wedge 1, wedge 22 are undertaken axially and radial location by the Step Shaft arranging on mandrel 1, described expansion sleeve 3 outsides are wound with deformable sheet materials, injuring part while preventing expansion sleeve 3 tensioner, described locking nut 5 is realized axially-movable by the thread segment of mandrel 1 end setting and is made tension mechanism tensioner and loosening.
Operation principle of the present utility model is:
Before processing, one end of the present utility model is contained on the scroll chuck of lathe, loads onto part to be processed, the other end is used tailstock jack-up, tighten locking nut 5, thereby make expansion sleeve 3 tensioner stretching parts, because inner bore of part has tapering, in the time of stretching, guaranteed the axial location of part.While unclamping locking nut 5 after part machines, stage clip 6 makes wedge block do axially-movable by elastic force, expansion sleeve 3 resiliences, and part is loosening, takes off part, completes time processing.
