Abstract
The utility model discloses a fastening device used for machining parts like a universal joint pin. The fastening device comprises a support seat and a press plate, wherein a groove I is formed at the top of the support seat, the press plate is arranged on the support seat, an arc groove II is formed upwards on the lower surface of the press plate, and a locking screw and a positioning key are arranged on the side wall of the support seat. When the fastening device is used, the excircle of the support seat is clamped by a flexible claw of a numerical control lathe, the two ends of a neck of the part like the universal joint pin to be machined are fixed on the support seat by the press plate, so that an inner hole and/or excircle of the part like the universal joint pin can be rapidly and accurately machined; in addition, the verticality of two vertical axial lines is guaranteed, the product percentage of pass is improved, and the machining efficiency is greatly improved.
Description
Technical field
The utility model relates to mechanical field, particularly a kind of fastener of cross Machining of Shaft-type Parts.
Background technology
In machine tool field, traditional turning is that processing is the face of the centre of gyration with the axial line, and the cross axial workpiece has two mutual vertical central lines; In tradition processing, acquire a certain degree of difficulty; Especially to the axial bore or the outer rim processing of cross axial workpiece, it is fixed, be difficult to guarantee the perpendicularity of two mutual vertical central lines owing to lack special fixture in the process; Percent defective is higher, and working (machining) efficiency is extremely low.
The utility model content
In view of this; The purpose of the utility model provides a kind of fastener of cross Machining of Shaft-type Parts; Can carry out accurately location and tightly fixing of axial line to the cross axial workpiece in the process; Guarantee the perpendicularity of two mutual vertical central lines, product qualified rate is high, and working (machining) efficiency improves greatly.
The purpose of the utility model realizes through following technical scheme: a kind of fastener of cross Machining of Shaft-type Parts; Comprise that the top is provided with the supporting seat of groove I and is arranged on the pressing plate on the supporting seat; The pressing plate lower surface is to the groove II that is provided with arc, and the supporting seat sidewall is provided with lock-screw I and positioning key.
Further; Also comprise the base that is arranged under the supporting seat; Be provided with the cylindrical springs bearing that opening makes progress between base and the supporting seat; Be provided with the axle center regulating block in the spring fastening, between spring fastening and the axle center regulating block spring be set, said supporting seat sidewall also is provided for the lock-screw II of dieback axle center regulating block;
Further, the low groove on the said supporting seat is in the shape of the letter V.
The beneficial effect of the utility model: the fastener of the cross Machining of Shaft-type Parts of the utility model; Comprise that the top is provided with the supporting seat of I groove and is arranged on the pressing plate on the supporting seat; The pressing plate lower surface is to the groove II that is provided with arc, and the supporting seat sidewall is provided with lock-screw I and positioning key.During use, the soft pawl of numerically controlled lathe is grasped the cylindrical of supporting seat, cross axle class workpiece axle journal two ends to be processed are fixed on the supporting seat by pressing plate, can realize fast the accurately endoporus and/or the cylindrical of processing cross axial workpiece; And the perpendicularity of two mutual vertical central lines is guaranteed, and product qualified rate is high, and working (machining) efficiency improves greatly.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is the structure cutaway view of the utility model;
Fig. 2 is the right view of Fig. 1.
The specific embodiment
Fig. 1 is the structure cutaway view of the utility model; Fig. 2 is the right view of the utility model.As shown in the figure: the fastener of the cross Machining of Shaft-type Parts of present embodiment; Comprise that the top is provided with the supporting seat 4 of groove I and is arranged on the pressing plate 8 on the supporting seat; The pressing plate lower surface is to the groove II that is provided with arc, and the supporting seat sidewall is provided with lock-screw I 6 and positioning key 7.During use, the soft pawl of numerically controlled lathe is grasped the cylindrical of supporting seat, the axle journal two ends of cross shaft-like workpiece 9 to be processed are fixed on the supporting seat groove I with pressing plate, carry out axial location through positioning key then, the back processing that is locked of lock-screw I; Can realize accurately processing fast the endoporus and/or the cylindrical of cross axial workpiece; And the perpendicularity of two mutual vertical central lines is guaranteed, and product qualified rate is high, and working (machining) efficiency improves greatly.
As further improvement to the foregoing description; Also comprise the base 1 that is arranged under the supporting seat; Be provided with the cylindrical springs bearing 2 that opening makes progress between base 1 and the supporting seat 4; Be provided with axle center regulating block 21 in the spring fastening, between spring fastening 2 and the axle center regulating block 21 spring 3 be set, said supporting seat sidewall also is provided for the lock-screw II 5 of dieback axle center regulating block.Base is set can directly be installed in forms such as base by thread cooperation on the main shaft of machine tool with it, enlarges practicality.Simultaneously, carry out the perpendicularity adjusting of axial line through the axle center regulating block.Because of the size of workpiece to be processed in the vertical direction has nothing in common with each other, therefore guarantee that through axle center regulating block 21, spring 3 and supporting seat 4 parts are vertical with the cross axle of locating again with the process tool keeping parallelism at vertical direction.
As the further improvement to the foregoing description, the low groove on the said supporting seat 4 is in the shape of the letter V.Adopt v block in the present embodiment, go for the workpiece processing of different-diameter, enlarged the scope of application.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the aim and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
