Description
Technical field
The utility model relates to Machining Technology field, especially a kind of anti-skidding positioning fixture.
Background technology
Fixture is used for fixing processing work in machinofacture process, it is convenient to the device processed by workpiece, at present, the circular pieces such as bearing ring need to clamp by fixture in turnery processing process, conventional fixture comprises unitary clip and two body fixtures, the defect that wherein unitary clip is maximum is complex manufacturing technology, cost of manufacture height, therefore two body fixtures use comparatively general, how with bolts existing two body fixtures are, bolt pretightening is limited, and with clamping force not on one wire, duration of service easily there is relatively sliding in length, affect the processing quality of product.
Prior art discloses a kind of name and is called " a kind of outer clip fixture, application number is 201520240276.7 " patent, comprise at least two clamp bodies, clamp body comprises pawl seat and chuck, pawl seat comprises chassis arm and chuck arm, chassis arm is installed on chassis, chuck arm has bolt hole, by bolt and chuck Joint, the preliminary tension of bolt and the clamping force of chuck are in the same way, this device adopts two body structures, reduce manufacturing cost, and change the installation direction of joint bolt, make bolt pretightening and chuck clamping force in the same way, solve two contact surface slippage problems, but, in clamping process, if chuck holding force is not enough, easily cause workpiece landing, or workpiece slippage in the course of processing, defective work piece or equipment, affect the working accuracy of workpiece, stiffening piece and chassis arm and chuck arm are split structure in addition, can not well fit the right-angle surface of chassis arm and chuck arm corner, therefore the rigidity of the corner that the use of stiffening piece can not solve chuck arm and chassis arm thoroughly is low, the defect of intensity difference, can not well extend the work-ing life of fixture, add production cost.
Summary of the invention
In order to overcome the deficiency of existing clamp technology, the utility model provides a kind of anti-skidding positioning fixture, it is possible to is clamped by workpiece and locates, prevent from workpiece landing or add man-hour slippage occurring, improve the working accuracy of workpiece, extend the work-ing life of fixture, reduce production cost.
The utility model solves the technical scheme that its technical problem adopts, a kind of anti-skidding positioning fixture, comprise at least two clamp bodies, described clamp body comprises pawl seat and chuck, described pawl seat comprises chassis arm and chuck arm, described chassis arm is installed on chassis, described chuck arm is provided with bolt hole, it is connected with chuck by bolt, described chuck is provided with, with the section of chuck arm joint, the groove matched with chuck arm, described chuck whole installation is arc, the interior cambered surface of described chuck is provided with boss, described boss and chuck are integrated, the corner that described chuck arm connects with chassis arm is provided with arc transition face.
The beneficial effects of the utility model are, a kind of anti-skidding positioning fixture, by arranging boss on chuck, workpiece is positioned, prevent from workpiece landing or add man-hour slippage occurring, improve the working accuracy of workpiece, by arranging arc transition face at chassis arm and chuck arm corner, strengthen rigidity and the intensity of fixture, extend the work-ing life of fixture, reduce production cost.
