Description
Technical Field
The utility model relates to a clamping part for mechanical equipment, concretely relates to self-adaptation cone angle chuck.
Background
At present, the rapid development of the manufacturing industry cannot be realized, and particularly, the use of a numerical control lathe is realized. The chuck is an arm which can not be used for clamping a workpiece by a machine tool. The chuck has certain requirements on the shape clamping of a workpiece to be machined, the number of jaws is required to be corresponding to the number of the multi-edge shapes, and a clamping surface is parallel to the surface of the workpiece, so that the workpiece with a taper angle can be machined only by using an ejector pin.
When the existing workpiece is a forged piece of an automobile hub bearing mandrel, the shape of the forged piece is complex in order to save cost, and the workpiece is easy to form in the forging process due to the cone angle design. However, the chuck is required to be turned to adapt to a plurality of clamping surfaces of the workpiece when the workpiece is clamped, the workpiece is required to be propped by the ejector pin when the workpiece is turned, and the inner hole of the workpiece cannot be machined due to the reason of the ejector pin. The universal clamping jaw is a cuboid, a conical workpiece cannot be directly clamped, the workpiece can be clamped only by turning the workpiece out of an inclined plane similar to the workpiece, and the clamping process also needs to assist the ejector pin to fix the workpiece to prevent the workpiece from falling out.
Disclosure of Invention
The technical problem to be solved by the utility model is to provide a self-adaptive cone angle chuck, which clamps a conical surface workpiece, has simple and clear operation, low loss of processing accessories and improved production benefit; the waste of the clamping jaws can be reduced, and the safety and the stability are also improved.
The utility model provides a technical scheme that technical problem adopted is: a self-adaptive taper angle chuck comprises a chuck seat and a clamping jaw, wherein the clamping jaw comprises a clamping jaw I and a clamping jaw II, the clamping surfaces of the clamping jaw II and a conical workpiece are set to be conical cambered surfaces, and anti-skidding clamping jaws are arranged on the conical cambered surfaces; jack catch I and jack catch II pass through coupling assembling fixed connection, just establish convex sphere on the jack catch I, be equipped with on the jack catch II with convex sphere accordant connection's concave sphere.
Preferably, the connecting assembly comprises a connecting piece and a connecting screw rod, and the jaw I and the jaw II are respectively provided with a mounting groove for mounting the connecting piece and a mounting hole for locking the connecting screw rod.
As a further improvement, a spring piece which is mounted and limited with the clamping jaw I is arranged on the upper end face of the clamping jaw II, and the spring piece is fixed with the clamping jaw II through a bolt.
As a further improvement, the antiskid clamping nail is connected with an adjusting screw rod.
The utility model discloses a design into two parts to current jack catch, jack catch I and II centre gripping stress surfaces of jack catch design into a convex sphere and a concave sphere, and such design makes the atress along with the change on inclined plane, and the direction of force follows the change, and this is exactly the characteristics of sphere atress. To the machined part in batches, according to the product cone angle independent design jack catch II on the centre gripping inclined plane that corresponds, carve the serial number, in order to ensure the safety of centre gripping, still designed anti-skidding bail on the cone angle cambered surface, the nail point is absorbed in the work piece during the centre gripping, and the centre gripping is more firm like this, and supplementary thimble also can be saved.
The utility model discloses on lathe centre gripping part, need not reserve the centre gripping platform when designing the work piece blank, also need not change the work piece that the jack catch comes the different cone angles of centre gripping, the processing work piece does not need the thimble also can firmly the centre gripping. And the processing error caused by the sliding of the clamping jaws can be avoided. The end jump of a workpiece requires very high size, and almost zero error can be achieved.
The utility model has the advantages that when clamping the conical surface workpiece, the operation is simple, the loss of the processing accessories is low, and the production benefit is improved; the waste of the clamping jaws can be reduced, and the safety and the stability are also improved. The limiting spring piece is used for enabling the spherical centers of the two spherical surfaces of the clamping jaw I and the clamping jaw II to be staggered by a certain distance, and the workpiece is pulled back to be tightly attached to the chuck by the staggered distance in the process of clamping the workpiece, so that gapless positioning is completed, and the machining precision is improved. The setting of adjusting screw can be after anti-skidding bail has wearing and tearing, through adjusting screw adjustment anti-skidding bail expose the length of toper cambered surface.

Detailed Description
As shown in the attached figure 1, the self-adaptive taper angle chuck comprises a chuck base 1 and a clamping jaw, wherein the clamping jaw comprises a clamping jaw I2 and a clamping jaw II 3, the clamping surfaces of the clamping jaw II 3 and a conical workpiece 15 are set to be conical arc surfaces 6, anti-skidding clamping nails 11 are arranged on the conical arc surfaces 6, the nail tips sink into the workpiece during clamping, so that the clamping is firmer, auxiliary ejector pins can be omitted, and the anti-skidding clamping nails 11 are connected with an adjusting screw 14; jack catch I2 and jack catch II 3 pass through coupling assembling fixed connection, coupling assembling includes connecting piece 4 and connecting screw 5, be equipped with mounting groove 9 of erection joint piece 4 and the mounting hole 10 of locking connecting screw 5 on jack catch I2 and the jack catch II 3 respectively.
