Abstract

The invention relates to the field of piston machining devices and particularly discloses a piston machining tool capable of machining two grooves simultaneously and ensuring machining precision. The piston machining tool comprises a tool body, wherein a triangular claw disk is arranged on a spindle of the tool body, and knife rests capable of moving all around are arranged on the left side and the right side of the triangular claw disk. Two groove cutting knives are arranged on the knife rest on one side of the triangular claw disk at an interval, the distance between the two groove cutting knives is the same as that between two grooves on a piston, the top ends of the groove cutting knives are flushed, and a cutting knife is arranged on the knife rest on the other side of the triangular claw disk. By arranging the two groove cutting knives on one knife rest, the two grooves of the piston can be cut by a one-pass process; the distance between the grooves can be accurately control by controlling the distance between the groove cutting knives; furthermore, machining efficiency is greatly increased, and machining cost is reduced.

Description

Piston Machining lathe

Technical field

The present invention relates to Piston Machining apparatus field, especially a kind of Piston Machining lathe.

Background technology

In existing Piston Machining enterprise, when to two of the outer surface of piston Pocket Machinings, by successively processing respectively, and cause in process the positioning difficulty to groove high, error between two grooves that make to cut is larger, affect product quality, production efficiency is low simultaneously, and production cost is higher.

Summary of the invention

The object of the invention is to provide in order to solve the deficiency of above-mentioned technology a kind of and can realize two grooves and process simultaneously, guarantee the Piston Machining lathe of machining accuracy.

In order to achieve the above object, the Piston Machining lathe that the present invention is designed, it comprises machine body, on the main shaft of machine body, be provided with triangle pawl dish, the left and right sides at triangle pawl dish is respectively equipped with the knife rest that four direction moves all around, being provided with two and cutting groove cutter of interval on the knife rest of a side therein, and two distances of cutting between groove cutter are identical with the distance between two grooves on piston, and two tops of cutting groove cutter flush, and on the knife rest of opposite side, are provided with cutter.

As optimization, center at triangle chuck is provided with fore-set, the external diameter of fore-set is consistent with the internal diameter in the ball of piston hole, the front end of three claws of triangle chuck can stretch into internal piston clamping ball hole wall, can realize the inside at piston to the clamping of piston, guarantee can not interfere in the cylindrical cutting process to piston.

As optimization, opposite side with respect to triangle chuck on machine body is provided with Mobile base, in Mobile base, level is provided with support column, support column and fore-set are on same level straight line, support column can slide front and back in Mobile base, and the top of support column is in close triangle pawl dish one side, support column end is connected with the periphery that is arranged on the runner on Mobile base by connecting rod, runner center and support column center are on same straight line, the center of runner is fixed with pivoted arm, the other end of pivoted arm is connected with the external part that is arranged on the cylinder on Mobile base by bearing pin, and pivoted arm is connected by bearing pin with the external part of cylinder, piston is completed after the cutting of cylindrical and end face, with coordinating of support column and fore-set, realization is completely fixed piston, can avoid piston in two grooves while cutting process, triangle pawl dish is inadequate to the chucking power of piston, cause the trickle deflection of generation of piston, affect the precision of groove, simultaneously, support column rear end drives runner to rotate by cylinder, realization moves forward and backward support column, simultaneously when support column supports, support column, the center of connecting rod and runner is all in same straight line, realize self-locking, avoid support column that the phenomenons such as retraction occur, greatly improved support effect, thereby effective controlled working precision.

The resulting Piston Machining lathe of the present invention, it cuts groove cutter by be provided with two on knife rest, can two grooves of piston once have been cut by one-pass, simultaneously by cutting the control of the distance between groove cutter, realize the accurate control of the distance between groove, also can greatly improve working (machining) efficiency, cut down finished cost.
