Background technology
Currently, many enterprises when designing tooling, especially for processing circular product and need to process two in the same face
All it is to remove the product to be processed of locking using modes such as screw or clamping plates, and also need in processing when the tooling of a concentric circles
It processes at twice, in actual production because of locking force difference, product size precision is caused deviation occur, processing is same at twice
Dimensional accuracy is set deviation occur, and production efficiency is relatively low.
Utility model content
In order to overcome the deficiencies of the prior art and there are the problem of, the utility model provides a kind of firm grip, clamping and positioning
Three-jaw fixture with high accuracy.
The utility model is achieved through the following technical solutions：A kind of Three-jaw fixture comprising support shaft, in support shaft
It is arranged with clamping bushing, one end of support shaft is provided with positioning column, and the other end is provided with location hole, clamps described in being close on bushing
One end of positioning column is arranged with installation axle sleeve, and one end that the installation axle sleeve is close to the positioning column is provided with mounting base, installs
The both ends of installation axle sleeve in seat are respectively arranged with bearing, and one end that the support shaft is close to the location hole is provided with connection clip
Fixed, the both sides of the connection clamping sleeve offer clamping seam respectively, and the clamping between the connection clamping sleeve and installation axle sleeve is tucked inside the sleeve
It puts on and is provided with stop nut, the clamping bushing is also arranged with spring, and one end of spring is fixed on the nut, spring
The other end is fixed on installation axle sleeve and clamps on the guide copper sleeve being arranged between oversleeve.
Preferably, it is provided with the link block for stationary fixture in the mounting base, it is corresponding with the link block in mounting base
Position be provided with opening.
Preferably, it is fast to be provided with damping between the link block and the installation axle sleeve；The link block and it is set to peace
Fill the fixed block rotation connection on seat.
It is provided with dustproof cover at the top of the mounting base.
Three-jaw fixture provided by the utility model passes through the seam between stop nut and connection clamping sleeve, and connection
Clamping that gripping sleeve both sides open up seam easily, securely can be clamped fixation to workpiece, and can by the spring of setting
Deflection when control clamps, to realize that high accuracy positioning clamps.
