Abstract

The utility model relates to a processing device for rolling, honing and finishing an excircle, belonging to the technical field of mechanical processing. Ideal processing machinery are not arranged, traditional honing is not ideal, and precision is not high; therefore, finishing and processing for surfaces of the excircle are more difficult currently. One end of a rolling and honing rod of the utility model is provided with a rolling and honing head, and the right end of the rolling and honing rod is provided with a regulating device which can cause the rolling and honing rod to slide and can regulate the surface pressure of the rolling and honing head for a processed circle. The utility model has advantages of simple structure and easy use. The surface roughness of a processed surface can achieve Ra 0.4 to 0.1. Compared with a traditional rolling and honing method, the efficiency of the utility model can be enhanced by two to three times, surface quality is enhanced by one grade, and therefore, the utility model can be used for the mechanical processing for the surfaces of axial circles.

Description

Cylindrical rolls top gem of a girdle-pendant polishing and adds multiplexer

Title of the present utility model is that cylindrical rolls top gem of a girdle-pendant polishing and adds multiplexer, belongs to the Machining Technology field.

Difficulty is generally all compared in polishing processing with periphery, and traditional honing is difficulty on the one hand, and precision is difficult to reach very high degree.For this reason, the utility model has designed a kind of new multiplexer that adds, and makes cylindrical roll top gem of a girdle-pendant polishing and adds multiplexer.Add the structure of multiplexer and process principle as shown in drawings.

Each part name is as follows in the accompanying drawing:

1-rolls top gem of a girdle-pendant wheel (1) 2-lining 3-outer shaft 4-internal axle sleeve 5-rolling bearing (2)

6-end cap 7-spacer 8-mandrel 9-nut 10-jackscrew 11-rolling plover rod

12-spring 13-slide block 14-adjusts screw 15-lead key 16-top gem of a girdle-pendant bar base

Part

1,2,3,4,5,6 is assembled into parts, and name is called rolling plover head.By spacer (7), mandrel (8), nut (9) the parts rolling plover head is installed on the rolling plover rod (11), then rolling plover head can rotate around mandrel (8) freely, and the effect of jackscrew (10) is to prevent that mandrel (8) is moving; The left end head of rolling plover rod (11) is " U " body, the parts rolling plover head then is contained in it " U " in the shape groove, have lead key groove (17) on the right-hand member cylinder of rolling plover rod, this groove slides along lead key (15), with the guiding that guarantees that rolling plover rod (11) and parts rolling plover head can move forward and backward, lead key 15 is installed on the top gem of a girdle-pendant bar base (16) by bolt (18), this base cross section is L-shaped, cylindrical hole is arranged on it, be used to install rolling plover rod (11), this base low order end has screw hole, is used for installing adjusting following closely (14), in rolling plover rod (11) the right-hand member cylinder ladder cylindrical hole is arranged, be used for mounting spring (12) and slide block (13).Be clamped on the knife rest of employed lathe (as lathe, boring machine etc.) by top gem of a girdle-pendant bar base (16) when this being rolled top gem of a girdle-pendant instrument, the outer round surface that rolls top gem of a girdle-pendant wheel (1) should closely contact with the outer round surface of shaft-like workpiece, promptly roll top gem of a girdle-pendant wheel and must produce certain pressure, can roll top gem of a girdle-pendant processing workpiece machining surface.But the different top gem of a girdle-pendant conditions of rolling, this pressure also change thereupon, and promptly this pressure must be able to be adjusted easily.This adjustment divides two steps: the first step is coarse adjustment, i.e. traverse feed by mobile lathe cutter saddle realizes; Second step was fine setting, then adjust screw (14) by turning, this screw compresses or pull-off spring (12) by slide block (13), this spring force acts on the rolling plover rod (11), make rolling plover rod have trace to move in front and back, be trace adjusted roll top gem of a girdle-pendant wheel (1) to surface of the work roll top gem of a girdle-pendant pressure, reach the purpose of fine finishining or polishing processing.

The process of rolling top gem of a girdle-pendant processing work is: the shaft-like workpiece clamping is on the main shaft chuck and tailstock tool of lathe, workpiece is done initiatively rotation, rolling top gem of a girdle-pendant instrument is fixedly clamped on the knife rest of lathe by top gem of a girdle-pendant bar base (16), the top gem of a girdle-pendant wheel that rolls that rolls top gem of a girdle-pendant instrument is contacted with workpiece machining surface, and adjustment contact pressure, roll top gem of a girdle-pendant wheel under workpiece drives, do passive rotation around mandrel (8), and roll top gem of a girdle-pendant instrument and promptly roll top gem of a girdle-pendant wheel with lathe knife rest moving axially and do vertical reciprocating feed and move along machine tool guideway, thus workpiece machining surface is produced trickle honing effect, workpiece is after rolling the top gem of a girdle-pendant, and surface roughness can reach Ra0.4～0.1, has promptly reached the purpose of Precision Machining or polishing processing.

Need illustrate have following some:

1. the material main composition that rolls top gem of a girdle-pendant wheel is silicon carbide abrasive and binding agent etc.

2. roll top gem of a girdle-pendant surplus and be generally 0.01～0.06mm, roll top gem of a girdle-pendant number of times and determine, generally be no more than three times according to the initial roughness of rolling top gem of a girdle-pendant surplus size and surface of the work.

3. roll the top gem of a girdle-pendant and add man-hour, make roll top gem of a girdle-pendant wheel axis and axis of workpiece contour, but the angle that must tilt, but never two axial lines is parallel.

4. cooling-lubricant must fully and filter when rolling the top gem of a girdle-pendant, prevents to scratch part.

Originally the main distinction that adds multiplexer and traditional honing machining tool has following 3 points:

A. structure is different fully, and this is simple in structure, and operation is easily gone.

This instrument of b can be gone up at machine tool (as lathe, boring machine) and use, and honing must be used on special-purpose honing machine.

C. traditional honing must make honing head axis and axis of workpiece concentric, and is mainly used in inner bore honing processing, and is difficult to periphery processing, originally add multiplexer and then be used for periphery processing, and roll top gem of a girdle-pendant wheel axis must with the axis of workpiece angle that tilts.

Originally add multiplexer and improve 2～3 times than traditional honing method efficient, workpiece surface quality improves one-level, can be widely used in machinery, traffic, petrochemical industry and instrument industry, the outer round surface of axle metalloid part is carried out high efficiency, high-quality fine finishining or polishing processing.
