Abstract
The invention discloses a method for grinding a lead screw raceway by the aid of double grinding wheels. The method includes selecting the grinding wheels which are ground according to the shape of the section of the lead screw raceway; placing the two grinding wheels at corresponding positions inside the raceway to grind the raceway; completing machining of the left half of the raceway by the aid of one of the grinding wheels; completing machining of the right half of the raceway by the aid of the other grinding wheel; and obtaining the complete lead screw raceway. The grinding wheels in the shape of the section of a half raceway are used for grinding the raceway, the contact area of each grinding wheel and the raceway is reduced, grinding heat and lampblack are decreased, processing efficiency of a lead screw and precision of the lead screw are improved, and environmental pollution is reduced.
Description
Technical field
The invention belongs to field of machining, relate to a kind of processing method of leading screw raceway, specifically a kind of method of double abrasive wheel grinding leading screw raceway.
Background technology
Ball screw assembly, is an important component part of rolling function parts, and its performance and quality have embodied the development level of a national machine tool industry, also is an important motive force that the dynamo-electric industry of country develops to the high, precision and frontier direction simultaneously.Frictional resistance is little, transmission efficiency is high, positioning accuracy is high, transmission has characteristics such as invertibity because ball screw assembly, has, and therefore is widely used in machine industry and other associated mechanical industry.
Ball screw assembly, mainly is made up of parts such as ball-screw, ball nut, back device, ball, dust rings.Nut sleeve is on leading screw, and the helicla flute of leading screw and the helicla flute of nut constitute the helical duct of ball motion.Being processed with open helicla flute at the outer surface of leading screw is raceway, and wherein, the machining accuracy of leading screw is crucial.When grinding leading screw with emery wheel, requiring emery wheel to cut type and raceway, to cut type the same, and the leading screw raceway is only used 1 wheel grinding man-hour adding at present.Because the contact area of emery wheel and raceway is bigger, what oil smoke emitted when the corresponding increase of cutting force caused processing parts in the time of the grinding leading screw is many, and causes leading screw flexural deformation easily.
Summary of the invention
In order to overcome the problem that prior art exists; The method that the purpose of this invention is to provide a kind of double abrasive wheel grinding leading screw raceway; This method is cut molding sand wheel grinding race with two and half raceways, has reduced single emery wheel and raceway contact area, has reduced grinding heat and oil smoke; And improved the working (machining) efficiency and the leading screw precision of leading screw, reduce environmental pollution.
The objective of the invention is to realize through following technical scheme:
A kind of method of double abrasive wheel grinding leading screw raceway is characterized in that: this method is chosen the good emery wheel of reconditioning according to the cross sectional shape of leading screw raceway, and two emery wheels are placed in the raceway corresponding position come grinding race, and specific requirement is following:
1) according to the cross sectional shape reconditioning emery wheel A and the emery wheel B of leading screw raceway 1, the left-half of the grinding face of its medium plain emery wheel A and leading screw groove-section shape is suitable, and the right half part of the grinding face of emery wheel B and leading screw groove-section shape is suitable;
2) grinding face of emery wheel A is placed on the left-half of leading screw raceway, the grinding face of emery wheel B is placed on the right half part of leading screw raceway, and emery wheel A and emery wheel B lay respectively at the corresponding position, both sides of leading screw.
3) the leading screw raceway is processed, emery wheel A accomplishes the processing of left half of raceway, and emery wheel B accomplishes the processing of right half of raceway, obtains complete leading screw raceway.
Among the present invention, emery wheel A and emery wheel B can lay respectively at the both sides up and down and point-blank of leading screw.Because the interaction force of two emery wheels almost on same straight line, can effectively reduce leading screw because receive the leading screw flexural deformation that the emery wheel extruding produces like this.
The present invention adopts new processing method to the leading screw raceway, according to the type that cuts of leading screw raceway, and the corresponding good emery wheel of reconditioning of choosing, and two emery wheels are placed on corresponding position are used for grinding race.Add man-hour, an emery wheel is only processed left half of raceway, and the another emery wheel is only processed right half of raceway.When two emery wheels were all passed by stroke, the raceway of whole leading screw had also machined.
Compared with prior art, the present invention cuts molding sand wheel grinding race with two and half raceways, can reduce single emery wheel and raceway contact area, reduces grinding heat and oil smoke.Simultaneously, because the interaction force of two emery wheels almost on same straight line, can effectively reduce leading screw because receive the leading screw flexural deformation that the emery wheel extruding produces like this.The present invention can improve the working (machining) efficiency and the leading screw precision of leading screw, reduces the pollution to environment.

The specific embodiment
A kind of method of double abrasive wheel grinding leading screw raceway of the present invention; This method is according to the cross sectional shape of leading screw raceway; Choose the good emery wheel of reconditioning, and two emery wheels are placed in the raceway corresponding position come grinding race, Fig. 1 is the placement location sketch map of two emery wheels.Fig. 2 is the enlarged diagram of P position among Fig. 1.Specific requirement is following:
1) according to the cross sectional shape reconditioning emery wheel A and the emery wheel B of leading screw raceway 1, the left-half of the grinding face of its medium plain emery wheel A and leading screw groove-section shape is suitable, and the right half part of the grinding face of emery wheel B and leading screw groove-section shape is suitable;
2) grinding face of emery wheel A is placed on the left-half of leading screw raceway; The grinding face of emery wheel B is placed on the right half part of leading screw raceway; And emery wheel A and emery wheel B lay respectively at the corresponding position, both sides of leading screw, and emery wheel A and emery wheel B lay respectively at the both sides up and down and point-blank of leading screw 2.Because the interaction force of two emery wheels almost on same straight line, can effectively reduce leading screw because receive the leading screw flexural deformation that the emery wheel extruding produces like this.
3) the leading screw raceway is processed, emery wheel A accomplishes the processing of left half of raceway, and emery wheel B accomplishes the processing of right half of raceway, obtains complete leading screw raceway.
The present invention to be according to the type that cuts of leading screw raceway, the corresponding good emery wheel of reconditioning of choosing, and two emery wheels are placed on corresponding position are used for grinding race.Add man-hour, emery wheel A only processes left half of raceway, and emery wheel B only processes right half of raceway.When two emery wheels were all passed by stroke, the raceway of whole leading screw had also machined.
