Abstract
The utility model discloses a tool for guaranteeing coaxiality of a flange hole. The tool is suitable for machining a wheel hub in a final reduction assembly of a crawler bulldozer. According to the conventional machining method, a product is directly placed on a working table, alignment is performed by using an inner hole, the excircle is measured by using a gauge to guarantee inner and outer concentricity, then a flange hole is drilled and the coaxiality of the flange hole and the inner hole is required to be guaranteed; and the machining method is low in efficiency and cannot meet the existing production requirement. In order to solve the problems, the tool for guaranteeing the coaxiality of the flange hole is designed, consists of a double ended bolt, a pressing plate, a connecting shaft, a pedestal, a T-shaped block, a positioning block, a positioning pin, an inner hexagon screw and a nut, and is characterized in that the tool can be accurately and fixedly arranged on a working table of a machine tool; and the machine tool is only required to find the center of the tool, and then the product is directly placed on the tool, is positioned by the positioning block on the tool and pressed by the pressing plate contained in the tool, so that the alignment frequency can be reduced and the machining accuracy can be guaranteed. The tool has a simple structure and is convenient to operate, and the production efficiency can be effectively increased to meet the accuracy requirements.
Description
Technical field
The utility model is applicable to the processing of wheel hub in the final deceleration assembly of crawler dozer.
Background technology
Existing processing method is for first being placed directly in product on workbench, then use the endoporus centering, with one heart, then bore flange hole and will guarantee that flange hole and endoporus are coaxial inside and outside guaranteeing with table measurement cylindrical again, this processing method efficient is low can not satisfy existing production requirement.
The utility model content
The utility model is to overcome above-mentioned deficiency, and designing requirement and production equipment requirement according to product have designed a kind of frock that guarantees the flange hole axiality.
The utility model is comprised of stud, pressing plate, connecting axle, base, T-shaped, locating piece, alignment pin, soket head cap screw, nut, it is characterized in that and to be fixed on accurately frock on platen, lathe only need find the frock center, then product is placed directly in above frock, positioned by the locating piece on frock, then the pressing plate that utilizes frock to carry compresses, and can reduce the centering number of times and guarantee machining accuracy.
The beneficial effects of the utility model: simple in structure, the fabricating tools cost is low, and is reusable, easy to operate, can satisfy production requirement.
