Description
Technical field
The utility model relates to a kind of positioner of lathe, is specifically related to a kind of automotive hub numerically controlled lathe centralized positioning axle.
Background technology
Automotive hub build shaping after wheel hub blank need process further on lathe, accurate processing just needs workpiece to carry out clamping position accurately, circumferential clamping and positioning is normally carried out at wheel hub cylindrical in the traditional location of wheel hub, this location needs the run-out tolerance of wheel hub cylindrical little, if circle conference of beating caused Workpiece fixing inaccurate, and wheel hub blank easily deforms because of heat treatment, circle run-out tolerance is larger, cause location inaccurate, process inaccurate, affect the quality of product.At present, there are some and automotive hub blank will be carried out the device at center, but carrying out centralized positioning to wheel hub is insert in the centre bore of wheel hub by locating shaft, at this moment hub centre hole and locating shaft are rigid contact, when to locating shaft installation or removal wheel hub, usual needs force is comparatively large, and this just causes the centre bore easily damaging wheel hub.
Utility model content
For the defect that above-mentioned prior art exists, technical problem to be solved in the utility model is to provide a kind of automotive hub numerically controlled lathe centralized positioning axle of not fragile hub centre hole.
In order to solve the problems of the technologies described above, the utility model provides a kind of automotive hub numerically controlled lathe centralized positioning axle, comprise pedestal, positioning seat, slide, locating shaft and spring, positioning seat is the columnar structured of both ends open, positioning seat one end facing peripheral equipment is equipped with fixing lug boss, other end is inwardly provided with stop ledge, the fixing lug boss of positioning seat is provided with bolt hole, positioning seat is fixedly connected with pedestal by the bolt in bolt hole, slide is in the chamber of positioning seat and be slidably matched with positioning seat, the end of slide is provided with the chuck for being stuck in stop ledge, locating shaft is fixedly installed on positioning seat center, spring is arranged in positioning seat and two ends and offsets with pedestal and slide respectively.
Adopt the automotive hub numerically controlled lathe centralized positioning axle of said structure, the fixing lug boss of positioning seat is connected with pedestal by bolt, anatomical connectivity, be convenient to installing/dismounting safeguard, when wheel hub blank is installed to locating shaft, hub centre hole is aimed at locating shaft and is compressed, in compaction process, locating shaft promotes slide, slide slides the spring simultaneously extruded between itself and pedestal in the cavity of positioning seat, spring gives a cushion effect when installing wheel hub blank, play the effect of buffering, hub centre hole and locating shaft is avoided firmly to support hard rigid contact, prevent damage of product.When workpiece takes off, locating shaft is by spring ejection return.
Further, the one side that positioning seat and spring offset is provided with draw-in groove.Draw-in groove, for placing spring, plays spacing effect to spring.
Further, locating shaft center is provided with groove, and the bottom land of groove is provided with bolt hole.Locating shaft is connected with slide by bolt, and structure is simple, convenient disassembly.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model automotive hub numerically controlled lathe centralized positioning axle.
In figure, 1 is pedestal, and 2 is positioning seat, and 3 is slide, and 4 is locating shaft, and 5 is spring, and 21 is fixing lug boss, and 22 is stop ledge, and 31 is chuck, and 32 is draw-in groove, and 6 is workpiece.
Detailed description of the invention
Below in conjunction with drawings and Examples, technical solutions of the utility model are described in further detail:
As shown in Figure 1, the automotive hub numerically controlled lathe centralized positioning axle of a kind of embodiment of the utility model, comprise pedestal 1, positioning seat 2, slide 3, locating shaft 4 and spring 5, pedestal 1 is the frame of lathe, positioning seat 2 is the columnar structured of both ends open, positioning seat 2 one end facing peripheral equipment is equipped with fixing lug boss 21, fixing lug boss 21 circumference is drilled with bolt hole, positioning seat 2 is connected with pedestal 1 bolt by bolt hole, the model of bolt is herein M10 × 30mm, the other end of positioning seat 2 is provided with inside stop ledge 22, positioning seat 2 is columnar structured, so there is cavity in its inside, the end of slide 3 is circumferentially with chuck 31, chuck 31 diameter identical with the internal diameter of positioning seat 2 cylinder, it is identical that the external diameter of slide 3 and the stop ledge 22 of positioning seat 2 surround round internal diameter, so slide 3 slides just in the cavity of positioning seat 2, and be stopped boss 22 when sliding into edge and block, can not deviate from.The outside (namely can skid off the end face of positioning seat 2) of slide 3 is provided with locating shaft 4, and locating shaft 4 center has groove, and the bottom land of groove has bolt hole, and locating shaft 4 is connected with slide 3 bolt, and bolt model herein is also M10 × 30mm.The inner face (namely all the time at the end face of positioning seat 2) of slide 3 has draw-in groove 32, spring 5 is placed with in draw-in groove 32, spring 5 is herein stage clip, spring 5 two ends offset with pedestal 1 and slide 3 respectively, when installing workpiece 6, locating shaft 4 presses slide 3, and slide 3 slides in positioning seat 2, the power that slide 3 receives spring 5 is slided slowly, and spring 5 plays the effect of buffering; When taking off workpiece 6, slide 3 resets under the effect of spring 5.
Above the technical scheme that the utility model embodiment provides is described in detail, apply specific case herein to set forth the principle of the utility model embodiment and embodiment, the explanation of above embodiment is only applicable to the principle helping to understand the utility model embodiment; Meanwhile, for one of ordinary skill in the art, according to the utility model embodiment, detailed description of the invention and range of application all will change, and in sum, this description should not be construed as restriction of the present utility model.
