Abstract
The utility model discloses a post-processing shot-blasting protection tooling of a wheel hub machine, which comprises a tooling positioning disc, a center hole protecting cover and a plurality of polycrystalline diamond (PCD) protecting nails, wherein the tooling positioning disc is in a circular disc shape, a screw bolt hole is arranged in the center of the tooling positioning disc, a baffle edge matched with the middle position of a wheel hub blank is formed on the outer edge, the center position of the center hole protecting cover is also provided with a screw bolt hole and is connected with the tooling positioning disc through a screw bolt and a screw nut, and the PCD protecting nails are matched with PCD holes arranged on the wheel hub blank. The tooling positioning disc is characterized in that the wheel hub blank is fixed in a shot-blasting machine to protect the installing surface of the blank from being in contact with the outside, at the same time, the center hole protecting cover is fixed on the blank through the screw bolt and the screw nut, the machining surface of the center hole is completely covered, and the PCD protecting nails are directly matched with the PCD holes of the blank to complete cover the PCD machining surface.
Description
Technical field:
The utility model relates to the frock technical field, especially relates to ball blast protecting tool set-up after a kind of wheel hub machined.
Background technology:
Along with the development of automotive engineering and popularizing of automobile, people are more and more to the requirement of automobile additional properties, parts for automobile have also proposed equal requirement, the phenomenon that the technology of present application wheel hub can't avoid burr to leave over fully, for satisfying the lifting of user to wheel hub outward appearance and performance requirement, the ball blast operation can address this problem effectively after the increase machined before application.But existing tooling device can't protect installed surface, PCD hole, these machining surfaces of centre bore (these surface requirements do not have coating and cover) of wheel hub and do not damaged by the ball blast operation, thereby be necessary to develop a kind of new protecting tool set-up.
The utility model content:
The purpose of this utility model is the weak point that exists at prior art and ball blast protecting tool set-up after a kind of wheel hub machined is provided, and it has installed surface simple and compact for structure, as can to protect the wheel hub blank effectively, PCD hole, these machining surfaces of centre bore and is not damaged by the ball blast operation.
For achieving the above object, the ball blast protecting tool set-up includes tool locating dish, centre bore over cap and a plurality of PCD protection nail after the wheel hub machined of the present utility model, wherein, the tool locating dish is in the form of annular discs, the center offers bolt hole, and outer rim forms the rib that cooperates with wheel hub blank middle part; Centre bore over cap center also offers bolt hole, and links to each other with the tool locating dish by screw bolt and nut, and PCD protects the PCD hole of following closely with on the wheel hub blank to cooperate.
Preferred as technique scheme.Described tool locating dish middle part convexes with the step that cooperates with wheel hub blank centre bore.
Preferred as technique scheme.Described PCD protection nail is for step-like, and its middle part offers screw hole.
The beneficial effects of the utility model are: its tool locating dish does not contact the installed surface that the wheel hub blank is fixed on protection blank in the ball blast machine with the external world; by screw bolt and nut the centre bore over cap is fixed on the blank simultaneously; cover the centre bore machining surface fully, PCD protects nail then directly to cooperate with the PCD hole of blank and covers the PCD machining surface fully.Shot-blasting machine starts the exposed surface of back shot high speed impact blank, plays cleaning, strengthens the blank surface, makes the blank surface be stress state, thereby improves the mechanical performance and the case hardness of wheel hub.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is an overall structure schematic diagram of the present utility model;
Fig. 2 is the structural representation of tool locating dish;
Fig. 3 is the structural representation of center over cap;
Fig. 4 is the structural representation of PCD protection nail;
The specific embodiment:
Therefore the following stated only for embodying the preferred embodiment of the utility model principle, does not limit protection domain of the present utility model.
See that accompanying drawing 1 is to shown in Figure 4: the ball blast protecting tool set-up includes tool locating dish 10, centre bore over cap 20 and the quantity PCD protection nail 30 corresponding with the PCD hole number of wheel hub blank 100 after the wheel hub machined of the present utility model, wherein, tool locating dish 10 is in the form of annular discs, its middle part convexes with the step 12 that cooperates with the centre bore of wheel hub blank 100, tool locating dish 10 centers offer bolt hole 11, and outer rim forms the rib 13 that cooperates with wheel hub blank 100 middle parts; Centre bore over cap 20 centers also offer bolt hole 21, link to each other with nut 42 by bolt 41 between centre bore over cap 20 and the tool locating dish 10; The PCD protection nail 30 that cooperates with PCD hole on the wheel hub blank 100 is for step-like, and its middle part offers the screw hole 31 that screw 43 cooperates.
The utility model is at first placed wheel hub blank 100 in use on tool locating dish 10, put centre bore over cap 20 afterwards again, and with bolt 41 and nut 42 wheel hub blank 100 is fixed; Load onto screw 43 on PCD protection nail 30 end faces, and the PCD hole site on the corresponding wheel hub blank 100 is placed.After protecting tool set-up installs; the installed surface of wheel hub blank 100, centre bore and these machining surfaces of PCD hole are all covered by frock; during shot-blasting machine work; shot beats on the frock surface and wheel hub spoke, wheel rim etc. need the surface of application again, has cleared up the burr at spoke, wheel rim place and has strengthened the blank surface quality.
