Abstract

The present invention belongs to a manufacturing method of a rolling slide block of a straight rolling guiding rail, which relates to the keep for a rolling way and a rolling element of the rolling slide block of the straight rolling guiding rail, and a processing method for a lubrication groove. The method changes a radial grinding method for processing the rolling slide block of the straight rolling rail. The method processes from the axial direction of the rolling way of the slide block and realizes a corresponding shape and a needed position of the rolling way of the rolling slide block by using a line cutting method; the present invention realizes the cut for passing the central position of an axle of the rolling element of the rolling way of the slide block by using the line cutting method, keeps the rolling element rolling in the rolling way but from falling off by causing the size of an opening of the rolling way to be smaller than that of the rolling element, and a keeping device of the rolling element is not needed; lubrication grooves of which the shape and the number are free are cut out on the rolling way of the rolling slide block by using a cutting method, which are used for improving the lubricated conditions of the rolling element, the rolling slide block and the guiding rail.

Description

The rolling slide block manufacture method of linear rolling track

Technical field

The invention belongs to the rolling slide block manufacture method of linear rolling track, relate to the raceway of rolling slide block, the maintenance of rolling element, the processing method of oil-way.

Background technology

The manufacture method of line slideway rolling slide block (abbreviation slide block) is to adopt the radial grinding method to process at present, because slide block inboard raceways size is little, shape and position accuracy demand height, the emery wheel size is little during grinding, abrasion of grinding wheel is fast, the shape contour accuracy retention time is short, therefore needs constantly shape contour accuracy and the detection constantly and the position of adjusting emery wheel of trimming wheel.Linear rolling track belongs to high-accuracy product, its guide rail reaches micron order with the Geometrical Tolerance Principle that cooperates between slide block, processing difficulties, technical sophistication, the production cost height, only minority enterprise can produce in the world, as the SCHNEEBERGER of Switzerland, THK, the NSK of Japan, the Han River lathe that the HIWIN in Taiwan is domestic.Another problem that adopts the warp-wise grinding is that the raceway after the grinding can't keep rolling element, necessary design and installation rolling element holding device in addition, (seeing Chinese patent application CN200310102704.1 U.S. Patent number 20050213855) complicated the structure of rolling slide block, strengthen technology difficulty and increase manufacturing cost.Adopt the method for radial grinding can't on raceway, process oil-way in addition.

Summary of the invention

Defective in the radial grinding method that content of the present invention is to avoid processing rolling slide block at present and is adopted: the emery wheel size is little in the time of＜one〉grinding, reach corresponding grinding speed, the energy consumption that must adopt the high speed bistrique to be brought;＜two〉the emery wheel size is little during grinding, and abrasion of grinding wheel brings a large amount of consumption of emery wheel soon;＜three〉guide rail reaches micron order with the Geometrical Tolerance Principle that cooperates between rolling slide block, abrasion of grinding wheel is fast during grinding, the shape contour accuracy retention time is short, needs the shape contour accuracy of trimming wheel constantly and constantly detects the technology controlling and process problem of a series of complexity of bringing with the position of adjustment emery wheel;＜four〉need high-precision special processing equipment;＜five〉therefore the raceway opening part size after the radial grinding can't keep the fixing of rolling element, in addition design and installation rolling element holding device more than or equal to rolling axon center full-size;＜six〉method of radial grinding can't be processed the oil-way of any bar number of meaning shape on raceway; And the new processing method of invention.

Description of drawings:

Fig. 1 is the processing method of present radial grinding

Fig. 2 is the slide block that has roller holder

Fig. 3 was the raceway part of center cutting

Fig. 4 is the processing method of axially cutting with line from the slide block raceway

The explanation of the present radial grinding method of Fig. 1: the main shaft 9 that runs up drives emery wheel 8 and from radially cutting slide block raceway 2 is carried out grinding in the slide block inboard.Because slide block inboard raceways size is little, the emery wheel size is little, the slide block raceway has the very high requirement that cooperates with the guide rail raceway, finishing after the wearing and tearing of emery wheel appearance profile, the wearing and tearing, the measurement after the finishing and the adjustment of position, a series of control problems such as grinding force and rigidity and grinding efficiency make manufacturing processing technic very complicated and difficult.

Fig. 2 has the explanation of the slide block of roller holder: the slide block raceway opening part size after the radial grinding is more than or equal to rolling element 5 axial full-sizes, therefore fixing rolling element, must install 6 pairs of rolling elements of roller holder additional and be fixed, prevent that when guide rail 7 withdraws from slide block rolling element 5 from coming off from raceway.

The specific embodiment

The specific embodiment of the present invention reaches by following measure: process from the axial direction of slide block raceway, realize the geometry and the coordinate position of slide block raceway with the method for line cutting.See that its line of cut 4 of Fig. 4 cuts out the raceway 2 and the oil-way 3 of geometry status requirement on slide block 1.Realize the center cutting of rolling axon excessively of slide block raceway with the method for line cutting, see that Fig. 3 crosses 5 centers of rolling element with the method for line cutting and cuts out raceway 2 on slide block 1, make raceway opening part size fix rolling element and in raceway, roll and do not come off less than the axial full-size of rolling element.Need not the rolling element holding device.On the slide block raceway, cut out the oil-way of any bar number of arbitrary shape with the method for line cutting, improve the lubricating condition of rolling element and rolling slide block and guide rail.Compared with prior art, have and need not use wheel grinding, the energy consumption when having saved grinding, the correlated parts of rolling element holding device has been saved in the consumption of having saved emery wheel, has simplified the structure of rolling slide block, has reduced manufacturing cost.Characteristics and effect need not high-precision special processing equipments, can reach the geometry and the coordinate position requirement of rolling slide block raceway with the partial function of prior art and existing common apparatus.(common apparatus as; Archie AGIECUT VERTEX summer Mil ROBOFIL2030SI-TW etc., its contour accuracy be less than 0.001 millimeter, surface roughness Ra 0.05-0.1 micron) mature and reliable that possesses skills, technology is simple, and technological process is short, and is energy-conservation, and the working (machining) efficiency height is easily promoted.

Claims

1. the rolling slide block manufacture method of a linear rolling track is characterized in that processing from the axial direction of rolling slide block raceway, determines the geometry and the coordinate position of slide block raceway with the method for line cutting.

2. the rolling slide block manufacture method of linear rolling track according to claim 1, it is characterized in that crossing rolling axon center with the method for line cutting on rolling slide block cuts out raceway, make raceway opening part size less than the axial full-size of rolling element, thereby fixedly rolling element roll and does not come off in raceway.
