Description
Technical field
The utility model belongs to lathe location clamping technical field, is specifically related to the processing unit (plant) of the eccentric external diameter of a kind of axial workpiece.
Background technology
Compressor is the heart of air-conditioning, and axial workpiece (bent axle) is the kernel component of compressor.Eccentric external diameter on bent axle has following characteristics: eccentric external diameter center, 3 places and axial line are uniformly distributed.The processing difficulties of this Series Crankshaft: because eccentric external diameter is many, although the offset of eccentric external diameter is the same, process the center of each eccentric external diameter not in one direction everywhere, processing cannot be completed by clamped one time, each debugging bothers very much, length consuming time, inefficiency.
Chinese patent (application number: the fixture 201320334470.2) disclosing a kind of machining crankshafts eccentric shaft, , comprise pull bar, ring flange, briquetting, chuck body, movable V type block, guide post and fixing V type block, described pull bar passes ring flange and arranges with briquetting, described briquetting and chuck body are rotationally connected, the card of described chuck body offers square groove, described movable V type block and fixing V type block intert in square groove, described guide post is fixedly mounted on fixing V type block, described movable V type block interts on the guide bar, this patent structure is complicated, mainly solve bent axle long shaft external diameter size when fluctuating to some extent, eccentric size constancy is ensured by adjustment vee-block, and the technical problem that eccentric external diameter clamped one time has located processing can not be solved.
Summary of the invention
The purpose of this utility model is to provide the processing unit (plant) of the eccentric external diameter of a kind of axial workpiece, to solve in prior art eccentric external diameter cannot clamped one time complete processing, repeatedly need debug length consuming time, the low inferior technical problem of working (machining) efficiency.
The technical scheme that the utility model realizes the employing of its object is as follows:
The processing unit (plant) of the eccentric external diameter of a kind of axial workpiece, comprise location-plate, clamping seats, housing screw, wherein: described location-plate is fixed by screws on clamping seats, described housing screw is arranged on clamping seats for fixed eccentric shaft long end external diameter, described eccentric shaft long end termination is at least provided with 3 keyways, described location-plate be provided with described keyway with the use of positioning key.
Described keyway is respectively keyway A, keyway B and keyway C, and the centerlines of above three keyways is 120 °.
The beneficial effects of the utility model: compared with prior art, the eccentric external diameter processing unit (plant) of axial workpiece described in the utility model, uniform processing 3 place equal dividing and positioning keyway on part, the processing of this operation only need use index dial, and working (machining) efficiency is high; When processing 3 places' bias, change a keyway after only frock once need being adjusted to the right place and can process next eccentric external diameter, reduce manipulation strength adjustment number of times, ensure that three bias reach 120 ° and divide equally, improve the eccentric throw of product and the requirement of symmetry, working (machining) efficiency doubles.The utility model is by uniform processing three place positioning spline, and have adjusted the structure of fixture, thus ensure that the stability of the uniform decile of the eccentric external diameter in processing parts 3 place, by original ± 3 °, bring up to ± 1 °, reduce the processing intensity of operator thus improve output.

Detailed description of the invention
The technical solution of the utility model is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figure 1 and Figure 2, the processing unit (plant) of the eccentric external diameter of a kind of axial workpiece, comprise location-plate 1, clamping seats 3, housing screw 2, wherein: described location-plate 1 is fixed on clamping seats 3 by screw 9, described housing screw 2 is arranged on clamping seats 3 for fixed eccentric shaft 4 long end external diameter, described eccentric shaft 4 long end termination is at least provided with 3 keyways, described location-plate 1 be provided with described keyway with the use of positioning key 5.
Described keyway is respectively keyway A6, keyway B7 and keyway C8, and the centerlines of above three keyways is 120 °.
The processing unit (plant) of the eccentric external diameter of axial workpiece described in the utility model adds man-hour for process piece by piece, offset and the position of corresponding eccentric external diameter is guaranteed with the keyway location on the long end external diameter of eccentric shaft 4 and termination, first eccentric shaft 4 is put into clamping seats 3, positioning key 5 on the corresponding location-plate 1 of keyway A6 on the long end outer-diameter end face of eccentric shaft 4 develops and uses housing screw 2 to tighten up, then with the three-jaw aligning determination offset on lathe, after processing the eccentric external diameter in the first place, corresponding positioning key 5 clamping in the 2nd keyway B7 position after workpiece is rotated 120 degree tightens up, process the eccentric external diameter in the second place, corresponding positioning key 5 clamping in the 3rd keyway C8 position after workpiece is rotated 120 degree again tightens up, and processes the eccentric external diameter in the 3rd place.
Apparatus structure of the present utility model is simple, easy to use, can directly process an eccentric external diameter by positioning and clamping, and then rotate 120 ° of positioning and clamping, process second eccentric external diameter, by that analogy, process time is short, and efficiency is high.
Above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in previous embodiment, or carries out equivalent replacement to wherein some or all of technical characteristic; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of the utility model embodiment technical scheme.
