Abstract
The utility model relates to a four-claw fixture which comprises four claws and a round chuck; the claws are uniformly distributed and locked with the round chuck through bolts; the chucks are positioned with the round chuck through positioning keys which are manufactured on the bottom surfaces of the chucks; the positioning keys comprise longitudinal positioning keys and vertical positioning keys, which are manufactured on the bottom surfaces of the longitudinal positioning keys; and elastic compensation joints are manufactured on the inner sides of the connecting positions of the vertical positioning keys and the longitudinal positioning keys. According to the fixture, the structure is simple, the design is scientific and reasonable, the cost is lower, and the stability and positioning precision when a work piece is processed on a machine tool are effectively improved.
Description
Technical field
The utility model belongs to tooling fixture field, especially a kind of four paws jig.
Background technology
The four paws fixture structure mainly comprises circular chuck and four claws, four claws are installed on circular chuck, realize workpiece location by four claws again, required precision is higher during processing work on lathe, workpiece installation must be located and clamped before processing, this just requires connecting key and the keyway machining accuracy on circular chuck of claw bottom surface very high, and 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 four paws jig is provided, and this fixture 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 four paws jig, comprise four claws and circular chuck, claw is by bolt and the uniform locking of circular chuck, positioning key and circular chuck that claw is made by the bottom surface are located, positioning key comprises longitudinal register key and the perpendicular positioning key of making in longitudinal register key bottom surface, and it is shaped with the elastic compensating seam at perpendicular positioning key and longitudinal register key link position inboard.
And, be shaped with claw on described claw and eject the hole.
Advantage of the present utility model and beneficial effect are:
This four paws jig, comprise four claws and circular chuck, claw is by bolt and the uniform locking of circular chuck, positioning key and circular chuck that claw is made by the bottom surface are located, positioning key comprises longitudinal register key and the perpendicular positioning key of making 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, this fixture structure is simple, design science rationally, cost is lower, effectively improve workpiece in stability and the positioning accuracy of machine tooling.
Description of drawings
Fig. 1 is the front view of the utility model claw;
Fig. 2 is the rearview of Fig. 1;
Fig. 3 is the left view of Fig. 1;
Fig. 4 is the utility model structural representation (four claws is installed on circular chuck).
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 four paws jig, comprise four claws 1 and circular chuck 7, claw is by bolt 8 and the uniform locking of circular chuck, positioning key and circular chuck that claw is made by the bottom surface are located, positioning key comprises longitudinal register key 4 and the perpendicular positioning key 5 of making in longitudinal register key bottom surface, and it is shaped with elastic compensating seam 6 at perpendicular positioning key and longitudinal register key link position inboard.Bolt hole 2 on described claw is prepared in perpendicular positioning key both sides, is shaped with claw on described claw between bolt hole and ejects hole 3.
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.
