Abstract
Process a special fixture for acetabular cup liner, comprise and strut axle, strut screw and pressurization nut, described in strut the clamping position fluting of axle, have one in groove perpendicular to the endoporus in axle center, two of described endoporus is tapered chamfering structure; The described screw that struts is provided with tapered configuration away from screw thread one end, and has two flanks, described in strut screw the taper chamfering structure of tapered configuration and endoporus coordinate, described flank can coordinate fluting position with anti-rotation; One end of described pressurization nut is tapered configuration, coordinates with the taper chamfering structure of endoporus, and the endoporus of described pressurization nut is screwed hole, and struts screw and matches.The utility model structure is simple, easy to use, can install two pieces product during use, processes positive and negative two surfaces respectively.By numerically controlled lathe or turning-milling complex processing, surface uniform can be obtained, the product of dimensionally stable, and surface is without crushing defect, production efficiency advantages of higher.
Description
Technical field
The utility model relates to artificial prosthesis machining tool technical field, is specifically related to a kind of fixture carrying out using when acetabular cup liner processes outer surface on numerically controlled lathe.
Background technology
In hip prosthesis, acetabular cup liner is critical component in replacement of total hip, and wherein, the Internal Spherical Surface of liner was even more important with coordinating between bulb, the ball of liner carries fretting wear, so for the size of liner and surface roughness requirements and important.Liner is as non-standard, the profile of each producer is all different, and complex contour, scroll chuck conventional in machining cannot meet its processing request, especially this procedure of turning, traditional clamping pattern processing, easily causes surface to crush, the distortion of Total Product folder, causes size or roughness to meet the demands.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned the deficiencies in the prior art, provides a kind of special fixture processing acetabular cup liner, and this fixture has the advantages such as easy for installation, positioning precision is high, product batch production efficiency high, good stability, clamping not damaged.
The utility model solves the problems of the technologies described above adopted technical scheme:
Process a special fixture for acetabular cup liner, comprise and strut axle, strut screw and pressurization nut, described in strut the clamping position fluting of axle, have one in groove perpendicular to the endoporus in axle center, two of described endoporus is tapered chamfering structure;
The described screw that struts is provided with tapered configuration away from screw thread one end, and has two flanks, described in strut screw the taper chamfering structure of tapered configuration and endoporus coordinate, described flank can coordinate fluting position with anti-rotation;
One end of described pressurization nut is tapered configuration, coordinates with the taper chamfering structure of endoporus, and the endoporus of described pressurization nut is screwed hole, and struts screw and matches.
Compared with prior art, the utility model has following beneficial effect: structure is simple, easy to use, can install two pieces product during use, processes positive and negative two surfaces respectively.By numerically controlled lathe or turning-milling complex processing, surface uniform can be obtained, the product of dimensionally stable, and surface is without crushing defect, production efficiency advantages of higher.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As Figure 1-5, a kind of special fixture processing acetabular cup liner, comprises and struts axle 1, struts screw 2 and pressurization nut 3, described in strut the clamping position fluting of axle, have one in groove perpendicular to the endoporus in axle center, two of described endoporus is tapered chamfering structure; The described screw that struts is provided with tapered configuration 6 away from screw thread one end, and has two flanks 5, described in strut screw the taper chamfering structure of tapered configuration and endoporus coordinate, described flank can coordinate fluting position with anti-rotation; One end of described pressurization nut is tapered configuration 8, coordinates with the taper chamfering structure of endoporus, and the endoporus of described pressurization nut is screwed hole, and struts screw and matches.
Strut screw through the endoporus strutted on axle, workpiece 4 is installed and position shown in Fig. 2, then pressurization nut screwed in and tighten, now, the conical surface contacts and slotted section can be strutted, cause and strut axle outer round surface and inner hole of workpiece fits, frictional force can be produced with workpiece after pressurization, thus workpiece is fixed.Then fixture is installed on the scroll chuck of numerically controlled lathe, completes the clamping of workpiece.
