Abstract
The invention provides a rounding method for boning emery sticks. The method comprises the following steps: heating emery sticks and an emery stick frame to 80-90 DEG C; connecting the emery sticks to the emery stick frame with a binder and then placing into a boning head body before solidifying the binder; placing into a cylinder jacket having a same diameter with the boning head body; adding a heavy article on the upper part of a boning head, for pressing a conical shaft of the boning head, completely expanding the emery stick frame and causing all the emery sticks to tightly cling to an inner wall of the cylinder jacket; and taking out the boning head after the binder is completely solidified. The method has the beneficial effects of simple process, high efficiency, long service life of the emery sticks, low manufacturing cost of products, and high boning precision of an inner hole in the cylinder jacket.
Description
Technical field
The present invention relates to a kind of rounding method, be specifically related to a kind of honing emery stick rounding method.
Background technology
The bistrique of present air cylinder sleeve of engine inner bore honing, after emery stick is solded into many emery stick framves, the bistrique body of packing into; Because the error of the sum of errors layer thickness of the foozle of emery stick frame, emery stick height itself; Many emery stick framves on grinding head body, can not form one just round, and cylindricity do not reach requirement yet, needs revise with more waste and old cylinder jacket the just circle and the cylindricity of bistrique emery stick; Not only wasted the attrition of human and material resources and lathe; And shortened the limited operating life of emery stick, and increased the manufacturing cost of product, reduced operating efficiency.
Summary of the invention
The technical problem that the present invention will solve provides a kind of honing emery stick rounding method, utilizes honing emery stick rounding method of the present invention to come the honing air cylinder sleeve of engine, high efficiency, and the emery stick long service life, production cost is low, improves cylinder jacket honing quality.
The technical scheme that technical problem adopted that the present invention will solve is: be heated to emery stick and emery stick frame in 80 ℃ of-90 ℃ of scopes, connect emery stick and emery stick frame with binding agent, take advantage of in the bistrique body of packing into when binding agent does not solidify; Put into cylinder jacket again with diameter; Add the weight compressing honing head axis of cone on the top of honing head, force the whole spreadings of emery stick frame, make all emery sticks all be close on the inboard wall of cylinder liner; After treating that binding agent solidifies fully, take out honing head and can use.
Beneficial effect of the present invention is: technology is simple, and efficient is high, the long service life of emery stick, and the low cost of manufacture of product, the cylinder sleeve bore honing precision is high.
The specific embodiment
1. the cylinder liner diameter of selecting a cylinder sleeve bore and honing head external diameter to be equal to mutually, cylinder sleeve bore cylindricity are less than 0.005mm:
2. emery stick and emery stick frame are placed on the electrothermal plate, turn on the power switch;
3. heating plate is heated in 80 ℃ of-90 ℃ of scopes;
4. evenly place binding agent in the emery stick frame groove;
5. with specific purpose tool emery stick is inserted in the emery stick frame groove, and compress;
6. close dull and stereotyped heating power supply;
7. when the temperature of treating emery stick and emery stick frame drops to 30 ℃-40 ℃, respectively the emery stick frame is inserted in the bistrique body (axis of cone is transferred to minimum position);
8. bistrique integral body is put into ready cylinder sleeve;
9. add a weight on the top of the bistrique axis of cone, make the axis of cone descending, force emery stick to be close to inboard wall of cylinder liner;
10. solidifying the back taking-up fully can use.
Claims (1)
1. the present invention provides a kind of honing emery stick rounding method, it is characterized in that: be heated to emery stick and emery stick frame in 80 ℃ of-90 ℃ of scopes, connect emery stick and emery stick frame with binding agent; Take advantage of in the bistrique body of packing into when binding agent does not solidify, put into cylinder jacket again, add the weight compressing honing head axis of cone on the top of honing head with diameter; Force the whole spreadings of emery stick frame; All emery sticks all are close on the inboard wall of cylinder liner, treat that binding agent solidifies fully after, take out honing head and can use.
