55-degree assembled guide rail positioning locking installation structure

Abstract

The invention provides a 55-degree assembled guide rail positioning locking installation structure. The structure comprises a guide rail groove part assembled by an asymmetric inner concave slide plate and an insert, and a slide block part assembled by a base and an isosceles trapezoid-shaped 55-degree slide block; the 55-degree slide block and the base are connected as a whole through up-down fastening by a vertical connecting screw I; the insert is inserted in a right trapezoid-shaped gap; the insert and the inner concave slide plate are connected as a whole through up-down fastening by a vertical connecting screw II; the insert is horizontally pushed towards a 55-degree dovetail inclined surface through a fastening screw penetrating through the outer side of a 90-degree vertical surfaceof the inner concave slide plate in a direction perpendicular to the connecting screw II; and a 55-degree wedged inclined surface of the insert is leant against the 55-degree slide block to realize tight sliding fit between the guide rail groove part of the dovetail guide rail and the slide block part. The structure is small in size, high in precision, firm and reliable in assembly connection andsimple in machining and installation, overcomes the difficulty of difficult assembly of the dovetail guide rail, achieves excellent wear resistance, and can meet the process demands of precise numerical control machine tool guide rails.

Description

technical field [0001] The invention belongs to the technical field of machine tool guide rails, and in particular relates to a 55° assembled guide rail positioning and locking installation structure. Background technique [0002] At present, in order to solve the large volume of the dovetail guide rail with integrated structure, it is not easy to process, the assembly of the dovetail sliding friction joint surface is labor-intensive and time-consuming; and it is limited by the material itself; the wear resistance of the guide rail is not ideal; it cannot meet the process requirements of high-precision CNC machine tools technical problems; now we have independently developed and designed a 55° assembled guide rail that is easy to process and easy to assemble (see figure 1 ); By substituting heat-treated bearing steel for the partial material at the sliding friction joint surface of the guide rail, the wear resistance and technological level of the guide rail are effectively ...

[0002] At present, in order to solve the large volume of the dovetail guide rail with integrated structure, it is not easy to process, the assembly of the dovetail sliding friction joint surface is labor-intensive and time-consuming; and it is limited by the material itself; the wear resistance of the guide rail is not ideal; it cannot meet the process requirements of high-precision CNC machine tools technical problems; now we have independently developed and designed a 55° assembled guide rail that is easy to process and easy to assemble (see figure 1 ); By substituting heat-treated bearing steel for the partial material at the sliding friction joint surface of the guide rail, the wear resistance and technological level of the guide rail are effectively improved; however, for the assembled guide rail, compared with the integrated guide rail, the most critical issue is On the basis of ensuring the structural rigidity of the assembled composite parts; how to avoid shaking and offset at the joints of the assembled composite parts; moreover, especially for the finally installed inlays, how to ensure that the inlays are firmly connected without shaking; Make the finally installed inserts can be close to the slider of the dovetail guide rail; make the guide rail groove part of the dovetail guide rail and the guide rail slider fit closely; to meet the various process requirements, the following technical solutions are proposed
