Abstract
A wheel hub upper die surface turning clamp belongs to the field of machining equipment. The wheel hub upper die surface turning clamp comprises a wheel hub, fixing blocks, fixing clamps, a fixing seat, a base, a bearing table and a positioning pin. The base is provided with the fixing seat, the fixing seat is provided with the bearing table, the bearing table is provided with the positioning pin, and the positioning pin is provided with the wheel hub; both ends of the base are provided with the fixing clamps, both ends of the fixing seat are provided with the fixing blocks, and the rim of the wheel hub is arranged on the fixing blocks; the fixing clamps are in an L shape and are fixed onto the base through a rotating motor; the positioning pin is in a ring-shaped structure. The wheel hub upper die surface turning clamp has multiple stress points, thereby achieving uniform stress during machining and being small in errors between an upper die and a lower die and very convenient to use.
Description
Technical field
The utility model relates to a kind of wheel hub patrix facing fixture, belongs to machining equipment field.
Background technology
Due to the process structure characteristic more complicated of Hub Castings workpiece, its mach key is the beating degree that ensures wheel rim; Because this product is to adopt gravitational casting at casting process, be subject to the impact of gravity and shrinkage factor, lower die face is shaped more stable than upper die face.The error that in the error ratio that lower die face produces, die face produces is little, and the error that lower die face produces is 6 ‰, and the error that is to say generation is 20～30, and the error that upper die face produces is 2 times of lower die face; In addition, die sinking is to carry out under the high temperature of 410 DEG C, can cause the phenomenon of distortion when upper die face is opened, and lower die face is to adopt top-opening type just to there will not be the heavily phenomenon of distortion; Next is that surface is out-of-flatness because the dead end face of upper die face is sprue gate, still directly accommodates by lathe at present, causes peripheral stressed vacuum, and therefore after processing, upper and lower mould error is large, is a urgent problem at present.
Summary of the invention
The purpose of this utility model is to provide a kind of wheel hub patrix facing fixture.
Problem to be solved in the utility model is the large deficiency of existing lathe processing wheel hub upper and lower mould error.
Wheel hub patrix facing fixture, comprises wheel hub, fixed block, geometrical clamp, holder, base, bearing platform and alignment pin, on described base, holder is installed, and bearing platform is installed on holder, and alignment pin is installed on bearing platform, and wheel hub is installed on alignment pin; Base two ends are provided with geometrical clamp, and holder two ends are provided with fixed block, and wheel hub edge is positioned on fixed block.
Described geometrical clamp is L-type, is fixed on base by rotary electric machine.
Described alignment pin structure in the form of a ring.
The utility model has the advantages that: this fixture has multiple stress points, make to add man-hour stressed evenly, upper and lower mould error is little, uses suitable convenience, should have market prospects widely.
Brief description of the drawings
Fig. 1 is the front view of the utility model wheel hub patrix facing fixture;
Fig. 2 is the side view of the utility model wheel hub patrix facing fixture;
Fig. 3 is the enlarged diagram of the bearing platform of the utility model wheel hub patrix facing fixture;
In figure: 1, wheel hub 2, fixed block 3, geometrical clamp 4, holder 5, base 6, bearing platform 7, alignment pin.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
Wheel hub patrix facing fixture, comprise wheel hub 1, fixed block 2, geometrical clamp 3, holder 4, base 5, bearing platform 6 and alignment pin 7, on described base 5, holder 4 is installed, bearing platform 6 is installed on holder 4, alignment pin 7 is installed on bearing platform 6, wheel hub 1 is installed on alignment pin 7; Base 5 two ends are provided with geometrical clamp 3, and holder 4 two ends are provided with fixed block 2, and wheel hub 1 edge is positioned on fixed block 2.
Described geometrical clamp 3 is L-type, is fixed on base 5 by rotary electric machine, conveniently wheel hub 1 is carried out to secondary and fixes.
Described alignment pin 7 structure in the form of a ring, provides large-area fixing contact-making surface.
Using method of the present utility model: base 5 is arranged on digital control processing platform, wheel hub 1 is fixed on to bearing platform 6 by alignment pin 7, just can be rotated and process, owing to having fixed block 2, alignment pin 7, geometrical clamp 3 three place's stress points, therefore stability under loading mismachining tolerance is little.
