Description
Technical field
The utility model relates to the anchor clamps that use in the lathe part processing, specifically is a kind of turning clamp with the Machining of Shaft-type Parts of not processing endoporus that is applicable to.
Background technology
Automobile hub axle tube is mainly used in the wheel limit supporting at press welding axle housing and engineering truck drive axle two ends, is the class vitals on the automobile chassis.Its blank adopts the drop stamping moulding, has not machining characteristics of endoporus, and through the blank that drop stamping technology is made, its interior metal tissue has the fine and close metal streamline that distributes vertically, thereby can greatly improve the anti-fatigue life of part.For guaranteeing that its interior metal streamline is not destroyed, and requires its endoporus not process.Such part cylindrical has high dimension precision and Geometrical Tolerance Principle.Because endoporus requires not process,,, therefore can't guarantee the dimensional accuracy and the Geometrical Tolerance Principle of cylindrical processing owing to be machined surface not as the endoporus of benchmark if adopt conventional scroll chuck chucking endoporus processing excircles.Prior art adopts the method processing excircles at two top lifting axe pipe orifice two ends, but because clamping force is not enough, is difficult for guaranteeing the dimensional accuracy and the Geometrical Tolerance Principle of cylindrical.
Summary of the invention
The purpose of this utility model provides a kind of turning clamp, is used to process the axial workpiece that endoporus need not cut, and can guarantee the dimensional accuracy and the Geometrical Tolerance Principle of part cylindrical.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of turning clamp, be connected with the flange of lathe spindle, be used to process the axial workpiece that endoporus need not cut, it is characterized in that: have flange bolt flange connecting dish with lathe spindle, the chuck body that is connected with flange plate bolt, the mandrel that is slidingly matched with the chuck body endoporus, jaw more than three or three, chuck body is anterior cooperate with the ring flange hole taper and between be connected with key, the middle part has orientational cone-shaped surface, has the jaw groove that is intervally arranged on the excircle of rear portion, have the inclined-plane elongated slot corresponding on the described mandrel with jaw groove position, jaw is placed in jaw groove and the inclined-plane elongated slot, jaw has the clamping curved surface that cooperates with the part to be processed endoporus contacts cooperation with the inclined-plane with mandrel inclined-plane elongated slot inclined-plane, and described mandrel front end connects a pull bar.
Described jaw is three, and corresponding jaw groove and inclined-plane elongated slot are three and are uniformly distributed along the circumference that described jaw clamps the groove that curved surface is provided with circumferencial direction respectively, and a Spring Card is stuck in the groove.
The utility model is owing to cooperates the accurate also Bolt Connection of locating by the taper hole frustum between ring flange and the lathe spindle flange, chuck body and ring flange adopt Bolt Connection and pass through the key transmitting torque, contacting cooperation with the workpiece orientational cone-shaped surface by orientational cone-shaped surface accurately locatees, make the jaw spreading after pull bar spurred forward, the workpiece endoporus is clamped, cooperate tailstock centre to hold out against, clamping force is big, can bear bigger cutting force, a clamping can guarantee the dimensional accuracy and the Geometrical Tolerance Principle of external cutting.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, the ring flange 1 of this turning clamp connects with the flange bolt of lathe spindle 7, and taper hole and the frustum that cooperatively interacts arranged respectively on the flange of ring flange 1, lathe spindle 7, guarantees the concentricity of ring flange 1 and lathe spindle 7.Chuck body 2 front ends stretch into the endoporus of ring flange 1, cooperate with endoporus that ring flange 1 has a tapering and between connect by key 3, be used to transmit moment of torsion.Chuck body 2 and ring flange 1 Bolt Connection, the middle part has orientational cone-shaped surface 2a, the rear end is uniformly distributed with three jaw grooves along the circumference, chuck body 2 centers have axially extending bore, mandrel 4 is slidingly matched with the axially extending bore of chuck body 2, the front end thread connection has pull bar 6, the rear end is corresponding with jaw groove position to have inclined-plane elongated slot 4a, jaw 5 has clamping curved surface that cooperates with the part to be processed endoporus and the inclined-plane that contacts cooperation with elongated slot 4a inclined-plane, inclined-plane, jaw 5 is placed in jaw groove and the inclined-plane elongated slot 4a, and its inclined-plane contacts cooperation with the inclined-plane of inclined-plane elongated slot 4a.When jaw 5 is installed, drop out in the jaw groove for preventing jaw 5, the clamping curved surface of jaw 5 is provided with the groove of circumferencial direction, and Spring Card 8 is stuck in the groove.Be processed with on the end endoporus of workpiece central siphon 9 and the identical chamfering of orientational cone-shaped surface 2a angle of taper, as the orientational cone-shaped surface that cooperates with orientational cone-shaped surface 2a on the chuck body 2.During work, the location cone angle of central siphon 9 is contacted cooperation with these anchor clamps orientational cone-shaped surface 2a, the rear portion of chuck body 2 and be placed on the jaw groove and inclined-plane elongated slot 4a in jaw 5 be positioned at central siphon 9 endoporus, the clamping curved surface of jaw 5 contacts with the cooperation of central siphon 9 endoporus, the other end of central siphon 9 holds out against with tail stock is top, the control cylinder piston rod spurs pull bar 6 and mandrel 4 left, and mandrel 4 moves to left and impels the radially outside spreading of three jaws 5 that central siphon 9 is clamped, and gets final product turning.Tailstock centre is return original position after the process finishing, and releasing lever, workpiece get final product.
