Abstract
The utility model relates to a fixture for a turning lathe. The fixture for the turning lathe comprises jaws and a chuck, wherein the jaws are locked on the chuck through bolts; the jaws are positioned on the chuck through locating keys respectively arranged on bottom faces of the jaws; and the root part of the inner side of the locating key of each jaw is provided with an elastic compensation joint. The fixture is simple in structure, scientific and reasonable in design and lower in cost, and the stability and the positioning accuracy of a workpiece processed on a machine tool are effectively improved.
Description
Technical field
The utility model belongs to tooling fixture field, especially a kind of lathe jig.
Background technology
Lathe mainly comprises chuck and claw with fixture structure, claw is installed on chuck, realize workpiece location by several 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 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 lathe 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 lathe jig comprises claw and chuck, and claw is by bolt and locking chuck, and positioning key and chuck that claw is made by the bottom surface are located, and the inboard root of its positioning key at claw is shaped with the elastic compensating seam.
And described positioning key comprises longitudinal register key and the perpendicular positioning key of making in longitudinal register key bottom surface, is shaped with the elastic compensating seam at perpendicular positioning key and longitudinal register key link position inboard.
Advantage of the present utility model and beneficial effect are:
This lathe jig, comprise claw and chuck, claw is by bolt and locking chuck, positioning key and chuck that claw is made by the bottom surface are located, the inboard root of its positioning key at claw is shaped with the elastic compensating seam, and this fixture structure is simple, design science reasonable, 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 (three claws is installed on 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 lathe jig, comprise claw 1 and chuck 7, three claws are set on the present embodiment chuck, claw is by bolt 8 and locking chuck, the positioning key that claw is made by the bottom surface coordinates with the keyway on chuck realizes the location, and the inboard root of its positioning key at claw is shaped with the elastic compensating seam.The present embodiment positioning key shown in the drawings comprises longitudinal register key 4 and the perpendicular positioning key 5 of making in longitudinal register key bottom surface, 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.
Claims (2)
1. a lathe jig, comprise claw and chuck, and claw is by bolt and locking chuck, and positioning key and chuck that claw is made by the bottom surface are located, and it is characterized in that: be shaped with the elastic compensating seam at the inboard root of the positioning key of claw.
2. lathe jig according to claim 1 is characterized in that: described positioning key comprises longitudinal register key and the perpendicular positioning key of making in longitudinal register key bottom surface, is shaped with the elastic compensating seam at perpendicular positioning key and longitudinal register key link position inboard.
