Adjust the accuracy of machine tool guideway gib structure design

Adjust the accuracy of machine tool guideway 2020 - strip structure design 09 - 02 Cui Dongying 【 Qiqihar second machine ( Group) Limited liability company design institute, heilongjiang qiqihar 161005 】 Abstract: this paper mainly introduces a kind of adjustment accuracy of machine tool guideway strip structure. The structure is mainly to solve the existing adjustment accuracy of machine tool guideway gib scraping research effort, easy to fall off. It has the following characteristics: the lathe bed ( 1) With the slide block ( 4) Is placed between the strip ( 3) Article, and set the 3) With the slide block ( 4) Through the slope between cooperate, article described with the 3) And the bed ( 1) Contact surface paste with coating ( 2) 。 The adjustment of precision machine tool guideway gib installation is firm structure, easy to study, can improve the accuracy of machine tool. Key words: machine tool guide rail; Gib; Coating 1 background technology at present, with the rapid development of the machine tool industry, users are increasingly demanding on the accuracy of machine tools, especially for milling and boring machine and lathe bed position of slides vice guide clearance adjustment is especially important influence on the accuracy of machine tool. The guide rail gap adjustment is done by fillet with slope. Gib general fixed on the slide, the two face with a certain Angle, one side is plane contact with lathe bed, relative motion; On the other side is cant contact with the slide, the relative slide movement. When the general adjustment need artificial blowing strip plane. There are two kinds of a strip of material is cast iron material, the other is a cast aluminum material, cast iron material hardness is larger, blow grind laborious; Cast aluminum material hardness is a bit small, blow grind easier, but its fixed on the slide because the material is soft, with a combined with screw thread is easy to damage, the connection is not strong, lead to strip off easily, seriously affect the accuracy of machine tools. 2 technical content in order to overcome the existing adjustment accuracy of machine tool guideway gib scraping research effort, easy to fall off, this paper introduces a kind of adjusting the precision of machine tool guideway strip structure, the adjustment of precision machine tool guideway gib installation is firm structure, easy to study, can improve the accuracy of machine tools. This paper introduces the technical scheme is: a strip of adjustment of precision machine tool guideway structure, including the bed, slide, as described in the lathe bed and slide between strip is placed, and between strip and slide through cant fit, article described with the coating with the lathe bed contact surface bonding, article described with end by connecting plate are connected to the slide. This paper presents the new technical proposal has the effect of: by adopting the above scheme, note glue strip surface curing coating, has high strength, good abrasion resistance and prevent movement crawling the good performance, and easy to cut, such precision of debugging, can use artificial scraper scraping coating level, scraping easy, improve work efficiency; At the same time the gib installation structure firmer, can improve the accuracy of machine tool. Figure 1 3 illustrated instructions for the structure of this paper. Figure: 1 - Lathe bed, 2 - Coating, 3 - Gib, 4 - Slide 5 - Screw A, 6 - Adjust pad, 7 - Screw B, 8 - Connection plate. 4 concrete implementation way of combining the appended drawings to our technical proposal below for further details: by shown in figure 1, a strip of adjustment of precision machine tool guideway structure, including lathe bed 1, slide 4, described in the lathe bed 1 and slide is placed between the 4 set in article 3, set in article 3 and lathe bed 1 interface as the plane, and strip through cant fit between 3 and slide 4. Described in the article with the 3 ends connected by screw A5 and connection plate 8, and connection plate at the bottom of the eight screws are connected to the slide 4 B7, thus will set in article 3 and slide 4 fixed together, and the connection plate between 8 and slide 4 sets adjust pad 6. Described in the article with the 3 material for cast iron, on the plane that is in contact with the lathe bed 1 paste with coating on the surface of 2, 2 coating formed by injecting, after curing has high strength, good abrasion resistance and prevent moving parts from crawling performance, and easy to cut, this debug accuracy, can use artificial scraper scraping coating, scraping easy, improve work efficiency. Debug accuracy, for the first time through the milling machine will strip coating 2 surface semi-finishing, then slide 4 and lathe bed 1, 2 coating coated on the surface of cinnabar and gib the plug into the slide wedge gap between 4 and lathe bed guide rail, and then remove the strip, see the coating on the surface of cinnabar creasing, scraping the indentation, after repeatedly face plug plug and artificial blow grind ensure strip coating level and quantity of the lathe bed guide rail scraping the research point, which ensures the slide and the precision of lathe bed guide rail movement; Machine work after a period of time, guide clearance can be adjusted by adjusting the pad 6, guarantee the accuracy of machine tool. Five epilogue combination between combination between the moving parts of the machine tool accuracy, and reliability of motion is the key to the machine precision, this paper proposed a new adjustment accuracy of machine tool guideway strip structure, it is to solve the combination between combined with poor accuracy stable destabilise the movement precision of this kind of problem, by using the new structure, greatly improved my factory lathe bed of machine tool of the problem of the precision of combination between slide block and at the same time the technology is applied to the spindle and the combination of the post box structure, after debugging and measurement, spindle box and pillar between the precision and stability of the combination of old structure increased by nearly 30% than in the past, at the same time, this new structure will be applied to other similar products structure, the combination of new technology will provide our factory machine transformation and upgrading of products, improve the machine precision and stability of the machine tool.
