Abstract
The utility model belongs to a piston of an engine, and particularly belongs to a processing machine for a piston. A piston integrative processing machine, which comprises a spindle head system, a tooling gripper and a cutting tool, has the essential structure that the tooling gripper is fixed on a spindle head; the front end of the rotation center of the tooling gripper is provided with a positioning concave hole which is matched with a piston positioning lug boss; an outer ring is a positioning convex ring; a thimble is installed on a tail rack; the cutting tool is a combined cutting tool. The processing and the clamping of the utility model only act on an entity on a piston head, which eliminates deformation caused by clamping force. Processing smear metal on a positioning surface can be easily cleaned, which eliminates positioning error caused by the uncleanness of the positioning surface. In addition, the utility model once completes positioning surface processing, the rough turning of an outer diameter, the rough turning and the finish turning of an annular groove and the finish turning of the outer diameter, and improves the quality of products and productivity.
Description
Technical field
The utility model belongs to the piston of engine, especially belongs to the processing equipment of piston.
Background technology
Car internal diameter, car circular groove, this three process of car external diameter of existing piston processing are finished on three special-purpose boards respectively, be illustrated in figure 1 as the structural representation of existing circular groove processing machine, because car circular groove, car external diameter are processed on two boards respectively, twice clamping strengthens the coaxiality error in footpath at the bottom of outside piston and the circular groove, and outside piston and the increasing of circular groove lateral vertical side degree error, directly influence the operate as normal of piston in cylinder, strengthen discharging, even scuffing of cylinder bore, engine knock.
Summary of the invention
The utility model has overcome above-mentioned shortcoming, provides a kind of and can reduce the coaxiality error in footpath at the bottom of outside piston and the circular groove and the piston integrated processing machine of outside piston and circular groove lateral vertical side degree error.
The technical scheme that the utility model adopted is, a kind of piston integrated processing machine, comprise main tapping system, frock clamp, cutter, its structural feature is that frock clamp is fixed on the main tapping, the centre of gyration front end of this frock clamp has a location shrinkage pool that matches with the piston positioning boss, the outer ring is the protruding circle in location, and thimble is contained on the tailstock, and cutter is a gang tool.
Be locating surface with piston positioning boss and top land outer face like this, withstand the top of piston cavity with thimble, promptly the top with piston cavity is a clamping point, the clamping force of machining piston only acts on the entity with piston crown like this, and the piston remainder is not subjected to clamping force, has eliminated the distortion that causes because of clamping force, and locating surface is in the top land outside, the processing smear metal of locating surface is easy to clean out, and has eliminated the position error that does not totally cause because of locating surface, makes each form and position tolerance more stable.
Reverse shrinkage pool on the frock clamp.Eliminated the rotary freedom of workpiece like this, and can transmit bigger torsion and give workpiece, the requirement when satisfying the car circular groove.
Cutter comprises machining cutter, first knife rest, second knife rest, and upper surface cutter, circular groove cutter, lower surface cutter are determined mutual position and be fixed on the knife rest by the actual processing dimension of piston, and the external diameter cutter is fixed on second knife rest.The circular groove cutter per two in one plane.
--thick, finish turning circular groove---finish turning external diameter of finishing locating surface processing in a clamping has been eliminated twice clamping in the processing technology in the past and has been brought at the bottom of outside piston and the circular groove directly coaxiality error, thereby improved the quality of products and productivity ratio.
Cutter comprises machining cutter, first knife rest, second knife rest, three-tool post, upper surface cutter, circular groove cutter, lower surface cutter are determined mutual position and are fixed on first knife rest by the actual processing dimension of piston, smart external diameter cutter is fixed on second knife rest, and thick external diameter cutter is fixed on the three-tool post.
--rough turn external diameter--thick, finish turning circular groove---finish turning external diameter has been eliminated twice clamping in the processing technology in the past and has been brought at the bottom of outside piston and the circular groove directly coaxiality error, thereby improved the quality of products and productivity ratio to finish locating surface processing in a clamping.
First knife rest also has upper surface rose reamer, circular groove rose reamer, piston skirt rose reamer as required.
Chamfering on the workpiece can be machined together like this, save time, improve effect.
Advantage of the present utility model is that the clamping force of machining piston only acts on the entity with piston crown, the piston remainder is not subjected to clamping force, eliminated the distortion that causes because of clamping force, and locating surface is in the top land outside, the processing smear metal of locating surface is easy to clean out, eliminated the position error that does not totally cause because of locating surface, made each form and position tolerance more stable.--rough turn external diameter--thick, finish turning circular groove---finish turning external diameter has been eliminated twice clamping in the processing technology in the past and has been brought at the bottom of outside piston and the circular groove directly coaxiality error, improves the quality of products and productivity ratio and to finish locating surface processing in a clamping.
