Abstract
The invention discloses a fine turning clamp used for an automobile thin-wall part. The fine turning clamp comprises a hub base, and further comprises an elastic chuck and a screw. The left side of the hub base is detachably connected with a spindle of a machine tool, a spoke is arranged on the right side of the hub base, a fixed sleeve is arranged in the center of the hub base, the fixed sleeve and the spoke are integrated, and the elastic chuck comprises a sliding sleeve and fins, wherein the sliding sleeve and the fins are connected into the fixed sleeve in a siding mode. The multiple fins are circumferentially and evenly distributed on the outer edge of the sliding sleeve, the fins and the sliding sleeve are integrated and form a disc-shaped structure, the fins are arranged on the sliding sleeve in an inclined mode, an expansion joint is formed between every two adjacent fins, the screw penetrates through an inner hole of the sliding sleeve and is connected with the fixed sleeve through threads, and the threaded head of the screw abuts against the right end face of the sliding sleeve. According to the scheme, the fine turning clamp is simple in structure, easy to operate and beneficial to clamping the thin-wall part and greatly improves efficiency.
Description
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 essence automobile clamper, so that clamping thin sheet wall pieces, ensure crudy.
Car thin-wall part essence automobile clamper in this programme, comprise hub-type pedestal, also comprise elasticity chuck and screw, removably connect with machine tool chief axis on the left of hub-type pedestal, spoke is provided with on the right side of hub-type pedestal, hub-type base central is provided with the fixed cover with spoke one, elasticity chuck comprises and is slidably connected to slip cap in fixed cover and fin, some fin circumferential array be distributed on slip cap outer rim and with slip cap one, fin and slip cap form disk-like structure, fin is obliquely installed on slip cap, dilatation joint is provided with between two adjacent fins, screw is threaded with fixed cover through slip cap endoporus, screw head is against on slip cap right side.
Workpiece is located in elasticity chuck outer rim with endoporus, and the fin of elasticity chuck is against on hub-type pedestal, and tightening screw can be oppressed slip cap and axially be moved to left, and the fin of elasticity chuck is then outer to be opened Workpiece clamping, gets final product processing work; After machining, oppositely unscrew screw, fin resets, and elasticity chuck unclamps workpiece, can take off workpiece; This programme structure is simple, and processing ease, is convenient to clamping thin sheet wall pieces, substantially increases efficiency.
Further, fin outer end is integrally formed with arc, increases the location area of fin, makes elasticity chuck firm grip workpiece more.
Further, be provided with packing ring between arc and hub-type pedestal, packing ring is against on arc, and ensure that arc opens clamping work pieces outward, packing ring is provided with counterbore and is connected on hub-type pedestal by lock-screw, facilitates installing/dismounting.
Further, in dilatation joint, be provided with sealing rubber pad, prevent iron filings from entering into fixture inside, cause assembly precision to reduce.
Further, hub-type pedestal is circumferentially with three installing holes, is connected and fixed between Convenient book clip tool and machine tool chief axis.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention;
Fig. 2 is that the A-A of Fig. 1 is to echelon sectional view.
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: packing ring 1, elasticity chuck 2, screw 3.
Embodiment is basic as accompanying drawing 1, shown in Fig. 2: car thin-wall part essence automobile clamper comprises hub-type pedestal, also comprise elasticity chuck 2 and screw 3, hub-type pedestal is circumferentially with three installing holes, be connected and fixed between Convenient book clip tool and machine tool chief axis, spoke is provided with on the right side of hub-type pedestal, hub-type base central is provided with the fixed cover with spoke one, elasticity chuck comprises and is slidably connected to slip cap in fixed cover and fin, some fin circumferential array be distributed on slip cap outer rim and with slip cap one, fin and slip cap form disk-like structure, fin is obliquely installed on slip cap, fin outer end is integrally formed with arc, increase the location area of fin, make elasticity chuck firm grip workpiece more, packing ring 1 is provided with between arc and hub-type pedestal, packing ring is against on arc, ensure that arc opens clamping work pieces outward, packing ring is provided with counterbore and is connected on hub-type pedestal by lock-screw, facilitate installing/dismounting, dilatation joint is provided with between two adjacent fins, sealing rubber pad is provided with in dilatation joint, prevent iron filings from entering into fixture inside, assembly precision is caused to reduce, screw is threaded with fixed cover through slip cap endoporus, screw head is against on slip cap right side.
Workpiece is located in elasticity chuck outer rim with endoporus, and the fin of elasticity chuck is against on hub-type pedestal, and tightening screw can be oppressed slip cap and axially be moved to left, and the fin of elasticity chuck is then outer to be opened Workpiece clamping, gets final product processing work; After machining, oppositely unscrew screw, fin resets, and elasticity chuck unclamps workpiece, can take off workpiece; This programme structure is simple, and processing ease, is convenient to clamping thin sheet wall pieces, 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.
