Abstract

A grinding machine for the excircle arc R of piston ring is composed of machine body, grinding head, longitudinal and transverse feeding mechanisms, and features that the grinding head and head are arranged on the machine body. The axle centers of the headstock and the grinding head are positioned on the same horizontal plane, and the worktable panels of the headstock and the grinding head are orthogonally arranged on the lathe bed. The longitudinal and transverse feeding mechanisms of the headstock are both installed on a revolving plate, the revolving plate is installed on a working table panel at the lower part of the revolving plate through a vertical shaft, and the revolving plate can revolve 360 degrees relative to the axial lead of the vertical shaft. The machine can machine the switching arc R required by design, effectively ensure the product quality and improve the machining efficiency.

Description

Piston ring excircle circular arc R sharpening machine

The utility model relates to a kind of small-sized machine process equipment, specifically, is a kind of grinding machine of machining piston ring cylindrical circular arc R.

To the processing of piston ring excircle circular arc R, the method that adopts is to utilize lathe chamfering and mechanical chamfering to add hand grinding usually.The piston ring excircle circular arc R of lathe chamfering method processing, though chamfering is regular, switching place after its processing is an acute angle, thereby when part chromium plating, easily cause most advanced and sophisticated long-pending chromium, during grinding after carrying out chromium plating, the part often occurs and collapse chromium, thereby influenced the quality of product.The machinery chamfering adds hand grinding, although the acute angle of its switching place of taking on a new look slightly is difficult to guarantee the uniformity of part to be processed, owing to be to adopt artificial reconditioning, thereby the processing work efficiency is slow, also is difficult to guarantee the quality of product simultaneously.

The purpose of this utility model is, designs a kind of Special Equipment of machining piston ring cylindrical circular arc R, with the unified standard that guarantees part to be processed cylindrical circular arc R and the quality of product, overcomes above-mentioned deficiency.

Its purpose can be through following scheme implementation: this machine is by lathe bed, be contained in forming to driving mechanism in length and breadth of bistrique, headstock and bistrique above the lathe bed, headstock part, the axle center of headstock and bistrique is positioned at same horizontal plane, and both worktable panels, orthogonal thereto being installed in above the lathe bed.Below headstock and vertical, horizontal driving mechanism thereof, be provided with a widely different flap, this plate is assembled on the worktable panel of its underpart through vertical shaft group vertical shaft, and the relative vertical shaft axial line of widely different flap can be done 360 ° of widely different commentaries on classics.

Piston ring excircle circular arc R sharpening machine of the present utility model, because headstock bottom in holding workpiece, be provided with widely different flap, thereby can satisfy the processing request that designs workpiece switching circular arc R, realize the unified standard of part to be processed switching circular arc R, guarantee the crudy of product effectively, improve the processing work efficiency, overcome the deficiency that lathe chamfering and mechanical chamfering add hand grinding piston ring excircle circle R.

The concrete structure of piston ring excircle circular arc R sharpening machine of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is the front view of the piston ring excircle circular arc R sharpening machine that the utility model proposes.

Fig. 2 is the vertical view of piston ring excircle circular arc R sharpening machine.

Fig. 3 is the enlarged drawing of Fig. 1 along the A-A section.

Below in conjunction with Fig. 1,2,3, describe detail and operational circumstances in detail according to the piston ring excircle circular arc R sharpening machine that the utility model proposes.

This machine has one " L " shape lathe bed [1], orthogonal thereto bistrique worktable panel [2] and the headstock work top anti-[18] of being equipped with on it.Base plate [3] is installed on worktable panel [2] successively, cross slide [5], vertical planker [6], bistrique [8], and drive cross slide and the vertical handwheel [4] and the handle [7] that move of planker.On worktable panel [18], device has widely different flap [10], and its front end links to each other with worktable panel [18] through vertical shaft [9], and composition is rotationally connected, the 360 ° of widely different commentaries on classics of vertical shaft axial line relatively of widely different flap.Be the spry and light and rotation precision that guarantees that widely different flap rotates, the outside in that vertical shaft inserts the worktable panel section is equipped with upper and lower bearing [20], is provided with spacer [21] therebetween.Base plate [15] is installed on widely different flap successively, vertical planker [13], cross slide [14], headstock [12], and drive adjustment handwheel [16], the feeding handwheel [19] that vertical planker and cross slide move, on widely different flap, dispose the handle of shaking the head [17].At the headstock front end, device has the anchor clamps [11] of holding workpiece.

This machine operation process is as follows: earlier with piece-holder in anchor clamps [11], element for aligning tool with the special preparation of this equipment, insert in the vertical shaft centre bore, with dial gauge calibration element for aligning tool, find out the center line of vertical shaft, shake the vertical of headstock [12], horizontal handwheel [16], [19], make workpiece outer face and cylindrical joining, aim at the percentage gauge outfit, gripping handle [17] drives widely different flap and rocks from side to side on the other hand, the adjustment headstock is vertical, the traverse feed handle, find the workpiece peak, according to the circular arc R of workpiece design, it is vertical to adjust headstock again, transverse feed mechanism is to required size, start grinding head motor and headstock motor this moment, make slowly grinding work piece of emery wheel, during grinding, workpiece simultaneously should rock from side to side.When given circular arc R is arrived in the workpiece reconditioning, pull handle [7], make emery wheel break away from workpiece, and close two motors, at this moment, in anchor clamps, unload workpiece, finish processing.

Claims

A kind of piston ring excircle circular arc R sharpening machine, this machine is by lathe bed, bistrique, headstock and the bistrique of device on lathe bed, the vertical, horizontal driving mechanism composition of headstock part, the axle center of headstock and bistrique is positioned at same horizontal plane, and both worktable panels, orthogonal thereto being installed in above the lathe bed, it is characterized in that headstock and vertical, horizontal feed mechanism thereof are installed on the widely different flap, widely different flap is installed in through vertical shaft on the worktable panel of its underpart, and the relative vertical shaft axial line of widely different flap can be done 360 ° of widely different commentaries on classics.
