Abstract
The invention discloses a method for processing piston ball pits, the method of fast clamping a piston body by a clamping device and processing the two inner side walls of the piston body by a milling cutter is adopted, during processing, two big ball pits are cut on the two inner side walls of the piston through firstly utilizing a milling cutter with big diameter, two small coaxial ball pits are further cut in the two big ball pits through utilizing the milling cutter with small diameter. The method is characterized in that a dual-main-shaft structure is adopted to respectively install the milling cutter with the big diameter and the milling cutter with the small diameter, the centers of the two milling cutters share the same plane with the axial centers of the piston ball pits, and relative motion between the milling cutters and the clamping device is utilized to enable the milling cutter with the big diameter and the milling cutter with the small diameter to cut the piston body one after another. The clamping device can be moved through preventing the positions between the main shaft and the milling cutters from changing, and also the main shaft and the milling cutter can be moved through keeping the clamping device unchanged, thereby enabling the milling cutter with the big diameter and the milling cutter with the small diameter to process the piston body one after another. The method can carry out the automatic production, does not need changing cutters and correcting by labor, improves the manufacturing efficiency, and reduces the manufacturing cost.
Description
Technical field
The present invention relates to a kind of machining process, especially a kind of processing method of piston ball pit.
Background technology
The axiality of piston ball pit, position degree are the important indicators of piston machine processing, because the required precision of piston processing is very high, axiality, position degree are controlled to such an extent that undesirablely will directly influence product quality, even therefore become substandard products, waste product.The main clamp piston idiosome that adopts of present piston ball pit processing, milling cutter carries out method for processing to piston idiosome two madial walls, add and utilize man-hour big footpath milling cutter to cut two big ball holes earlier at piston two madial walls, again change the path milling cutter then, utilize the path milling cutter in aforementioned two big ball holes, further to cut two coaxial bead holes again, and make easily that in exchanging knives process the position at milling cutter center changes, should say through reinstalling, again the position at its center of milling cutter of Jia Jining must change, thereby make that the axle center, ball hole of twice processing is inconsistent, influence the axiality of piston ball pit, the position that therefore can only in exchanging knives process, as far as possible keep the milling cutter center, deviation is less before making itself and tool changing, to improve piston mass, such mode wastes time and energy, and crudy is inevitable not high.
Summary of the invention
What the objective of the invention is to provide for the deficiency that solves above-mentioned technology a kind ofly guarantees that big footpath milling cutter is identical with path milling cutter center, avoids tool changing to produce deviation, improves the processing method of the piston ball pit of crudy.
In order to achieve the above object, the processing method of the piston ball pit that the present invention is designed, it adopts clamp piston idiosome, milling cutter carries out method for processing to piston idiosome two madial walls, add and utilize man-hour big footpath milling cutter to cut two big ball holes earlier at piston two madial walls, utilize the path milling cutter in aforementioned two big ball holes, further to cut two coaxial bead holes again, it is characterized in that adopting two main axle structures that big footpath milling cutter and path milling cutter are installed respectively, make two milling cutter centers and piston ball pit axle center at grade, utilize relatively moving of milling cutter and anchor clamps that big footpath milling cutter and path milling cutter are successively cut the piston idiosome.Add and to keep main shaft and milling cutter invariant position man-hour and mobile anchor clamps also can keep the anchor clamps invariant position and mobile main shaft and milling cutter, thereby big footpath milling cutter and path milling cutter are successively processed the piston idiosome.
Can adopt the mode of horizontal processing, its method is to adopt the two main axle structures of axle center on same horizontal plane that big footpath milling cutter and path milling cutter are installed respectively, make the along slope coordinate at two milling cutter centers identical, add and keep man-hour the along slope coordinate of milling cutter constant, and laterally relatively move with the anchor clamps generation, big footpath milling cutter and path milling cutter are successively cut the piston idiosome.
Can adopt the mode of vertical processing, its method is to adopt the two main axle structures of axle center on same perpendicular that big footpath milling cutter and path milling cutter are installed respectively, make the lateral coordinates at two milling cutter centers identical, add and keep man-hour the lateral coordinates of milling cutter constant, and vertically relatively move with the anchor clamps generation, big footpath milling cutter and path milling cutter are successively cut the piston idiosome.
Also can adopt the mode of oblique processing, as long as the two milling cutter centers of assurance and piston ball pit axle center are at grade, this plane can spatially be the variation of 360 degree, selects processing mode thereby can choose according to the production space.
Above-mentioned along slope coordinate refers to horizontal plane height in the vertical, and lateral coordinates refers to perpendicular distance in the horizontal.
Distance between described big footpath milling cutter and anchor clamps can be less than the distance between path milling cutter and anchor clamps.The convenient big footpath milling cutter that carries out earlier carries out the processing of path milling cutter again.
The processing method of the resulting piston ball pit of the present invention, utilize two main axle structures to guarantee two milling cutter centers and piston ball pit axle center man-hour at grade adding, make the piston of twice processing have identical axle center, thereby improve axiality, the position degree of product, improve the quality of products, adopt this method can carry out automated production in addition, it is manually accurate to need not artificial tool changing, improve production efficiency, reduced production cost.
