Abstract

The utility model relates to a clamping jaw having an elastic compensation function. The clamping jaw having the elastic compensation function comprises a clamping jaw body, a bolt hole is manufactured in the clamping jaw body, a longitudinal positioning key is manufactured in the bottom surface of the clamping jaw body, a perpendicular positioning key is manufactured in the bottom surface of the longitudinal positioning key, and an elastic compensation seam is manufactured on the inner side of a joint position of the perpendicular positioning key and the longitudinal positioning key. The clamping jaw having the elastic compensation function is beneficial to ensuring machining accuracy of workpieces and stabilization of quality of products, and is beneficial to improving of labor productivity and reducing cost.

Description

Claw with elastic compensating function

Technical field

The utility model belongs to tooling fixture field, especially a kind of claw with elastic compensating function.

Background technology

On lathe during processing work, for the surface that makes workpiece can reach drawing regulation size, geometry and with other surperficial specification requirements such as relative-position error, workpiece must be installed before processing and locate and clamp, claw is the workpiece holder on chuck, on general chuck, a plurality of claws are set and clamp workpiece, the key that claw is made by the bottom surface and bolt and chuck position and are fixedly mounted with, existing claw bottom surface positioning key requirement on machining accuracy is higher, the common machine process equipment is difficult to satisfy, cause processing cost higher, and position stability is relatively poor.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of claw with elastic compensating function is provided, and this claw structure is simple, design science reasonable, cost is lower, effectively improve workpiece in stability and the positioning accuracy of machine tooling.

The utility model solves its technical problem and is achieved through the following technical solutions:

A kind of claw with elastic compensating function, comprise a claw, be shaped with bolt hole on this claw, be shaped with the longitudinal register key in the claw bottom surface, be shaped with the perpendicular positioning key in longitudinal register key bottom surface, it is shaped with the elastic compensating seam at perpendicular positioning key and longitudinal register key link position inboard.

And the bolt hole on described claw is prepared in perpendicular positioning key both sides.

And, be shaped with claw and eject the hole on the claw between described bolt hole.

Advantage of the present utility model and beneficial effect are:

Originally the claw that has the elastic compensating function, comprise a claw, be shaped with bolt hole on this claw, be shaped with the longitudinal register key in the claw bottom surface, be shaped with the perpendicular positioning key in longitudinal register key bottom surface, it is shaped with the elastic compensating seam at perpendicular positioning key and longitudinal register key link position inboard, and this claw is conducive to guarantee machining accuracy, the stabilized product quality of workpiece; Be conducive to raise labour productivity and reduce costs.

The specific embodiment

The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.

A kind of claw with elastic compensating function, comprise a claw 1, be shaped with bolt hole 2 on this claw, be shaped with longitudinal register key 4 in the claw bottom surface, be shaped with perpendicular positioning key 5 in longitudinal register key bottom surface, it is shaped with elastic compensating seam 6 at perpendicular positioning key and longitudinal register key link position inboard, and the bolt hole on described claw is prepared in perpendicular positioning key both sides, is shaped with claw and ejects hole 3 on the claw between described bolt hole.

Elastic compensating seam of the present utility model can increase elastic compensating, in the situation that do not affect repetitive positioning accuracy, claw machining accuracy scope is relaxed.Former processes precision must be used numerical control machining center guarantee positioning accuracy higher than 0.1 μ m, and machining accuracy is relaxed to 0.5 μ m now, uses the common machine process equipment can satisfy positioning requirements.

Claims

1. claw with elastic compensating function, comprise a claw, be shaped with bolt hole on this claw, be shaped with the longitudinal register key in the claw bottom surface, be shaped with the perpendicular positioning key in longitudinal register key bottom surface, it is characterized in that: be shaped with the elastic compensating seam at perpendicular positioning key and longitudinal register key link position inboard.

2. the claw with elastic compensating function according to claim 1 is characterized in that: the bolt hole on described claw is prepared in perpendicular positioning key both sides.
