Abstract
The utility model belongs to the technical field of mechanical working for pistons, particularly relates to a full function comprehensive processing machine for piston pin holes. The utility model is characterized in that cutter holders of main shaft heads 1, 2 are also provided with outer chamfer cutters, main shaft heads 3, 4, a frock clamping and a pressing and supporting system are arranged on a symmetrical line of the central line of a rotating worktable which is provided with the two main shaft heads 1, 2, the pressing and supporting system is correspondingly arranged above the frock clamping, a half-precision boring cutter and a precision boring cutter are arranged on the cutter holders of the main shaft heads, and a positioning reamer cutter blade and an adjustable reamer cutter blade are arranged on cutter holders which are flexibly fixed on the main shaft heads. Accordingly, the utility model has the obvious advantages of low cost, little mounting error, high work efficiency, high precision of pistons machined and low labor intensity.
Description
Technical field: the utility model belongs to the Machining Technology field of piston, is specifically related to a kind of piston pin hole global function comprehensive machine.
Background technology: in the pin-and-hole processing of existing piston, earlier piston is fixed on the retaining ring groove machine clamp of two sides, with internal diameter seam location heavy boring pin-and-hole, processing annular groove; With internal diameter seam location piston is fixed on precision bored hole on the right boring machine clamp again; At last piston is propped up with skirt section end face and external diameter and being carried on the broach(ing) machine fraising and finishing the processing of piston is handled; Its heavy boring pin-and-hole, retaining ring groove, precision bored hole and fraising processing are finished on three lathes respectively, and existing needs No. three clampings, at least two workman's operations, make workpiece be easy to generate the clamping error, reduced the precision of piston, production efficiency is low, labour intensity is big, defect of high cost.
Summary of the invention: the purpose of this utility model is the defective that overcomes in the above-mentioned piston process, provides a kind of and reduces labor intensity, and enhances productivity and the machining accuracy of piston the piston pin hole global function comprehensive machine that reduces production costs.
The technical solution of the utility model is: a kind of piston pin hole global function comprehensive machine, form by the frock clamp on the rotary table of establishing rough bore cutter and retaining ring groove cutter, support on two main tappings, 1,2 knife bars symmetrical on the body, frock clamp top correspondence is provided with the pressure holding system, it is characterized in that: also be provided with outer rose reamer on main tapping 1,2 knife bars; With two main tappings 1,2 be provided with on the line of symmetry of rotary table center line main tapping 3,4, frock clamp and above the corresponding pressure holding system that is provided with; On the knife bar of main tapping, establish half smart hole boring cutter and smart hole boring cutter; On the flexible fixing knife bar of main tapping, be provided with location cutting blade and expansion reamer sheet.
Owing to adopt technique scheme, a clamping can be finished whole operations of piston pin holes such as heavy boring pin-and-hole, chamfering, two ends annular groove, precision bored hole, fraising, and four main tappings can be worked simultaneously, and during workpiece loading and unloading, right boring, fraising two-step can normally be processed; Thereby it is low to have a cost, and the clamping error is few, the piston precision height of operating efficiency and processing, the advantage that labour intensity is low.
Description of drawings: come the technical solution of the utility model is described further below in conjunction with the drawings and specific embodiments.Accompanying drawing is a structural representation of the present utility model.
The specific embodiment: with reference to the accompanying drawings, a kind of piston pin hole global function comprehensive machine, form by the frock clamp 8 on the rotary table 7 of establishing rough bore cutter 5 and retaining ring groove cutter 6, support on two main tappings, 1,2 knife bars symmetrical on the body, frock clamp 8 top correspondences are provided with the pressure holding system, also are provided with outer rose reamer 9 on main tapping 1,2 knife bars; With two main tappings 1,2 be provided with on the line of symmetry of rotary table 7 center lines main tapping 3,4, frock clamp 8 and above the corresponding pressure holding system that is provided with; On the knife bar of main tapping 3, establish half smart hole boring cutter 10 and smart hole boring cutter 11; On main tapping 4 flexible fixing knife bars, be provided with location cutting blade and expansion reamer sheet 12.
