Abstract
The utility model relates to a tooling fixture, in particular to an automatic-centering clamping vice. A left screw rod and a right screw rod are provided with left-hand threads and right-hand threads and longitudinally penetrate into the clamping vice; a left-hand nut and a right-hand nut are respectively fixed on an upper vice body and then form screw pairs with the left screw rod and the right screw rod; parallel movement of two upper vice jaws is realized between the upper vice body and a lower vice body through a guide rail and a guide groove; and through horizontal movement of the left-hand nut and the right-hand nut, the two vice jaws are driven to move synchronously, horizontally and oppositely, so the aim of automatically centering is achieved. By adopting the automatic-centering clamping vice, not only is the aim of automatically centering achieved, but also work pieces with different varieties and different specifications can be processed during once mounting, and the mounting and clamping precision cannot be influenced by errors of overall dimensions of parts, so the processing quality and the working efficiency can be greatly improved; and in addition, all processing technologies used by the automatic-centering clamping vice are conventional mechanical processing technologies, so the manufacturing cost is low, and the implementation and the popularization are easy.
Description
Technical field
The utility model relates to a kind of frock clamp, particularly about a kind of grip vice.
Background technology
At present the workpiece that has centering to require is added man-hour, factory adopts the common machine folder vice of buying on the market to clamp usually, common machine folder vice clamps the position to be made up of regular jaw and moving jaw, and moving jaw is by feed screw nut driving-belt movable clamp port clamping work pieces.During work, at the part of each specification vice is carried out one-time positioning, the regular jaw of vice keeps motionless and the moving jaw motion adapts to the workpiece profile and realizes clamping function with this.Because there is error in the overall dimensions of workpiece, so the hole in piece part position symmetry error that processes is bigger, crudy is lower, and a kind of workpiece of every processing all will carry out one-time positioning to vice, and efficient is lower.
Summary of the invention
The purpose of this utility model: provide a kind of can automatic centering, one-time positioning can be carried out many size workpieces processing, improve the automatic centering grip vice of crudy and operating efficiency.
The technical solution of the utility model is: the automatic centering grip vice, comprise jaw, upper clamp, left and right sides spiral thick stick, limiting plate, left and right sides spin nut, lower clamp, described left and right sides spiral thick stick is the cylinder that revolves screw thread about having, vertical grip vice through automatic centering, form screw pair with left and right sides spiral thick stick after described left-handed nut and right-handed nut are individually fixed on the described upper clamp, described upper clamp bottom be provided with can with the guide groove of lower clamp guide rail engagement limits moving direction, can realize the parallel mobile fit clearance of bit by the confinement plate that is fixed on the upper jaw with the lower clamp maintenance.
Described upper clamp can be designed to square structure;
Described upper clamp quantity can be two.
The beneficial effects of the utility model are: because the utility model drives the level of synchronization move toward one another of two upper jaws by left-handed nut and right-handed nut's horizontal movement, not only can realize the purpose of automatic centering, and once mounting can be carried out size workpiece processing how wide in variety, can not influence clamping precision, can improve crudy and operating efficiency greatly because of the error of part overall dimensions.In addition, the used process technology of this automatic centering grip vice all is conventional mechanical processing, and low cost of manufacture realizes and popularization easily.
Description of drawings
Fig. 1, Fig. 2 are structural representations of the present utility model, wherein 1 jaw, 2 upper clamps, 3 left-right turning screw rods, 4 limiting plates, 5 left-handed nuts, 6 right-handed nuts, 7 lower clamps.
The specific embodiment
Please refer to Fig. 1, Fig. 2.Left-right turning screw rod 3 is for revolving the cylindrical part of screw thread about having, be positioned at from centering vice middle part, vertically run through in the vice two ends, left-right turning screw rod 3 one ends are fixed in the lower clamp hole, spacing by the taper pin ring washer, rotation during left-right turning screw rod by being separately fixed at the left and right sides spin nut 5 that forms screw pair on two upper clamps 2 with leading screw, 6, drive two upper clamp 2 locking phases to moving, upper clamp 2 can be designed to square structure, the guide groove that the bottom is provided with cooperates with lower clamp 7 upper rails, the restriction moving direction, upper clamp 2 keeps constant fit clearance by the limiting plate 4 that is fixed on the upper clamp with lower clamp 7, two jaw keeping parallelisms are moved, synchronous or expansion, make the workpiece that is clamped on the automatic centering grip vice jaw 1, in the vice clamping range, can both realize bi-directional synchronization and move along with jaw large or small, it is constant with the relative position that is fixed on the automatic centering grip vice on the lathe that the workpiece symmetrical center line of different size keeps, reach the purpose of automatic centering, jaw 1 by bolting on upper clamp 2, can be for convenience detach, change jaw.
Claims (3)
1. automatic centering grip vice, comprise jaw, upper clamp, left and right sides spiral thick stick, limiting plate, left and right sides spin nut, lower clamp, it is characterized in that, described left and right sides spiral thick stick is the cylinder that revolves screw thread about having, and vertically through the grip vice of automatic centering, forms screw pair with left and right sides spiral thick stick after described left-handed nut and right-handed nut are individually fixed on the described upper clamp, described upper clamp bottom be provided with can with the guide groove of lower clamp guide rail engagement limits moving direction, keep realizing the parallel mobile fit clearance of bit by confinement plate and the lower clamp that is fixed on the upper jaw.
