Abstract

The invention discloses a clamp for machining an automobile thin-wall part. The clamp comprises a spindle, a screw, a pressing sleeve, butterfly springs and a centering sleeve, wherein the lower end of the spindle is provided with a taper shank, the middle part of the spindle is provided with a positioning boss, and the upper end of the spindle is provided with a cylindrical fixing section; a first butterfly spring, the centering sleeve and a second butterfly spring are arranged on the cylindrical fixing section in a sleeving manner in sequence; the lower end of the first butterfly spring is abutted against the positioning boss; the upper end of the second butterfly spring is provided with the pressing sleeve which slides along the axial direction of the cylindrical fixing section; the excircle size of the pressing sleeve is smaller than the size of an inner hole of a workpiece; the center of the upper end of the cylindrical fixing section is connected with the screw; the screw is abutted against the pressing sleeve. According to the scheme, the clamp has a simple structure and is easy to operate, the clamping of the thin-wall part is facilitated, and the efficiency is greatly improved.

Description

Car thin-wall part fixture for processing
Technical field
The present invention relates to car thin-wall part production and processing technical field.
Background technology
Thin-wall workpiece is because have lightweight, feature such as saving material, compact conformation etc., and thin-walled parts is applied in each industrial department increasingly extensively.
But the processing of thin-walled parts is more thorny, reason is that thin-walled parts poor rigidity, intensity are weak, and the as easy as rolling off a log distortion of work in-process, not easily ensures the crudy of part, affect production efficiency, the machining accuracy how improving thin-walled parts will be the topic that industry is more and more concerned about.
Summary of the invention
The invention is intended to provide a kind of car thin-wall part fixture for processing, so that clamping thin sheet wall pieces, enhance productivity.
Car thin-wall part fixture for processing in this programme, comprise axle, also comprise screw, gland, butterfly spring and centring sleeve, axle lower end is taper shank, it is positioning boss in the middle part of axle, axle upper end is cylinder canned paragraph, cylinder canned paragraph overlaps vertically successively the first butterfly spring, centring sleeve and the second butterfly spring, first butterfly spring lower end is against on positioning boss, second butterfly spring upper end is along cylinder canned paragraph gland in axial sliding, gland excircle dimension is less than inner hole of workpiece, cylinder canned paragraph upper end center is connected with screw, screw is against on gland.
Taper shank is contained in machine tool chief axis, and workpiece is located on centring sleeve with endoporus, and workpiece end face is against on positioning boss, and tightening screw makes the first butterfly spring, the second butterfly spring distortion by workpiece swelling; This programme structure is simple, and processing ease, is convenient to clamping thin sheet wall pieces, substantially increases efficiency.
Further, the tapering of taper shank is No. 2 Morse's tapers, and Morse's taper is the international standard of a tapering, for stationary fit accurately to locate.Because tapering is very little, utilize the principle of frictional force, certain moment of torsion can be transmitted, again because be taper fit, so can dismantle easily, in the certain limit of same tapering, workpiece is free to dismounting, operationally can not have influence on result of use again simultaneously.
Further, between screw and gland, be provided with packing ring, increase the active area between screw and gland.
Further, the arragement direction of the first butterfly spring, the second butterfly spring is consistent, and the first butterfly spring, the second butterfly spring force direction are consistent, by workpiece firm grip.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: screw 1, packing ring 2, gland 3, second butterfly spring 4, centring sleeve 5.
Embodiment is substantially as shown in Figure 1: car thin-wall part fixture for processing, comprise axle, also comprise screw 1, packing ring 2, gland 3, butterfly spring and centring sleeve 5, axle lower end is taper shank, the tapering of taper shank is No. 2 Morse's tapers, Morse's taper is the international standard of a tapering, for stationary fit accurately to locate.Because tapering is very little, utilize the principle of frictional force, certain moment of torsion can be transmitted, again because be taper fit, so can dismantle easily, in the certain limit of same tapering, workpiece is free to dismounting, operationally result of use can not be had influence on again simultaneously, it is positioning boss in the middle part of axle, axle upper end is cylinder canned paragraph, cylinder canned paragraph overlaps vertically successively the first butterfly spring, centring sleeve and the second butterfly spring 4, first butterfly spring, the arragement direction of the second butterfly spring is consistent, first butterfly spring, second butterfly spring force direction is consistent, by workpiece firm grip, first butterfly spring lower end is against on positioning boss, second butterfly spring upper end is along cylinder canned paragraph gland in axial sliding, gland excircle dimension is less than inner hole of workpiece, cylinder canned paragraph upper end center is connected with screw, packing ring is provided with between screw and gland, increase the active area between screw and gland, screw is against on packing ring.
Taper shank is contained in machine tool chief axis, and workpiece is located on centring sleeve with endoporus, and workpiece end face is against on positioning boss, and tightening screw makes the first butterfly spring, the second butterfly spring distortion by workpiece swelling; This programme structure is simple, and processing ease, security is high, substantially increases efficiency.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect the practicality of effect of the invention process and invention.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
