Abstract
The utility model relates to a small-displacement shaft sleeve which comprises a shaft sleeve, a boss, inner holes and an unloading slot, and the small-displacement shaft sleeve is characterized in that the upper and lower ends of the shaft sleeve are set as arc shapes, the boss is arranged on one side of the shaft sleeve, the other side of the shaft sleeve is set as a plane, two inner holes are arranged in the shaft sleeve, and the unloading slot is arranged between the two inner holes in the shaft sleeve. The machining technology is that the 10mm process boss is additionally arranged to a gear combination surface along the shape of the shaft sleeve so as to facilitate quick clamping and accurate positioning of a combined fixture. The production efficiency is greatly improved, and the labor intensity of workers is correspondingly reduced. The small-displacement shaft sleeve provided by the utility model has the beneficial effects of being convenient to clamp, shortening the machining time, conforming to the required accuracy of the drawing, and effectively reducing the production cost and equipment investment, being an effective measure for improving the product quality and production efficiency.
Description
Technical field
The utility model relates to a kind of float amount axle sleeve, is applied to rise in the external gear pump main and crucial part.
Background technique
Employed axle sleeve clamping trouble in the external gear pump in the existing technology, and the long processing time of axle sleeve, cost is high, can not reach and satisfy the requirement of gear pump mechanical efficiency.
Summary of the invention
The utility model technical problem to be solved is the deficiency that overcomes existing technology; A kind of float amount axle sleeve is provided, and the utility model solves the technological scheme that its technical problem adopted and is: the structure of the utility model comprises axle sleeve, boss, endoporus, compensating groove, it is characterized in that the two ends up and down of axle sleeve are arranged to circular-arc; One side of axle sleeve is provided with boss; The opposite side of axle sleeve is arranged to the plane, and axle sleeve is provided with two endoporus, is provided with a compensating groove between two endoporus on the axle sleeve.
Course of working: the utility model is convenient to combined clamp quick-clamping and accurate status along the false boss of axle sleeve profile at gear junction plane increase 10mm.Improve manufacturing efficiency greatly, reduced labor strength simultaneously accordingly.The axle sleeve machining work process can be divided into seven steps: earlier with axle sleeve false boss and plane positioning and compress.Step 1: rough mill the plane, guarantee thickness size; Step 2: mill endoporus to size; Step 3: mill circular arc, to pattern size; Step 4: mill compensating groove, to pattern size, depth dimensions that assurance will be processed and the size of taking into account required precision; Step 5: the right boring endoporus, to pattern size; Step 6: finish-milling end face; Step 7: the processing reverse side, the finish-milling end face is to illustrated dimensions.Logical detent plug rule of process three-coordinate instrument and endoporus and roughness instrument reach the drawing processing dimension fully and require and the form and position tolerance critical field.It is applied to little displacement gear pump is had the occasion of required precision more.
The beneficial effect of the utility model is that the utility model clamping is convenient, has shortened process time, meets the drawing requirement precision, has effectively reduced cost of production and equipment input, is a kind of effective measures that improve product quality and production efficiency.
