Description
Technical field
The utility model relates to car thin-wall sleeve 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.
Utility model content
The utility model is intended to provide a kind of car thin-wall sleeve fixture for processing, so that clamping thin walled cylinder body, enhances productivity.
Car thin-wall sleeve fixture for processing in this programme, comprise axle, also comprise nut, gland, butterfly spring and centring sleeve, butterfly spring comprises the first butterfly spring, second butterfly spring, axle left end is provided with fixed handle and positioning boss, in the middle part of axle be with positioning boss one multidiameter, axle right-hand member is the threaded portion with multidiameter one, multidiameter overlaps vertically successively the first butterfly spring, centring sleeve, second butterfly spring and gland, first butterfly spring left end is against on positioning boss, first butterfly spring, centring sleeve is enclosed within large one section of multidiameter size, second butterfly spring is enclosed within gland outer rim, gland is provided with presenting a theatrical performance as the last item on a programme of offseting with the second butterfly spring right-hand member, gland slides axially along little one section of multidiameter size, threaded portion is connected with nut, nut left end is against gland right side.
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 nut 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 walled cylinder body, substantially increases efficiency.
Further, between gland and the second butterfly spring, be provided with pad, prevent gland end wear.
Further, between nut and gland, be provided with packing ring, increase the active area between nut and gland.
Further, the arragement direction of the first butterfly spring, the second butterfly spring is contrary, and the first butterfly spring, the second butterfly spring horizontal applied force are offset, resultant direction outwardly, by workpiece firm grip.
Further, one section of right-hand member that multidiameter size is little is provided with anti-rotation groove, and on gland sidewall, the corresponding anti-turn screw being provided with insertion anti-rotation groove, prevents from relatively rotating between gland and axle, cause wearing and tearing.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: nut 1, packing ring 2, gland 3, second butterfly spring 4, centring sleeve 5.
Embodiment is substantially as shown in Figure 1: car thin-wall sleeve fixture for processing, comprise axle, also comprise nut 1, gland 3, butterfly spring and centring sleeve 5, butterfly spring comprises the first butterfly spring, second butterfly spring 4, axle left end is provided with fixed handle and positioning boss, in the middle part of axle be with positioning boss one multidiameter, axle right-hand member is the threaded portion with multidiameter one, multidiameter overlaps vertically successively the first butterfly spring, centring sleeve, second butterfly spring and gland, first butterfly spring left end is against on positioning boss, first butterfly spring, centring sleeve is enclosed within large one section of multidiameter size, second butterfly spring is enclosed within gland outer rim, first butterfly spring, the arragement direction of the second butterfly spring is contrary, first butterfly spring, second butterfly spring horizontal applied force is offset, resultant direction outwardly, by workpiece firm grip, gland is provided with presenting a theatrical performance as the last item on a programme of offseting with the second butterfly spring right-hand member, pad is provided with between gland and the second butterfly spring, prevent gland end wear, gland slides axially along little one section of multidiameter size, threaded portion is connected with nut, packing ring 2 is provided with between nut and gland, increase the active area between nut and gland, nut left end is against gland right side, one section of right-hand member that multidiameter size is little is provided with anti-rotation groove, the corresponding anti-turn screw being provided with insertion anti-rotation groove on gland sidewall, prevent from relatively rotating between gland and axle, cause wearing and tearing.
Right side, threaded portion is provided with centre bore, can with top with the use of, strengthen the centering of this fixture.
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 nut 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 walled cylinder body, substantially increases efficiency.
Above-described is only embodiment of the present utility model, 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 the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect the effect of the utility model enforcement and the practicality of utility model.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.
