Description
Technical field
The utility model belongs to machine tool part field, especially combines roller guide structure with one relevant.
Background technology
Existing outer surface grinding machine is (as cylindrical grinder, internal groove grinding machine) workbench be installed on pedestal by feed mechanism, the guide rail of feed mechanism, general is all adopt straight-line rolling guide set and hydrostatic slideway pair, the guide rail of straight-line rolling guide set is fixedly installed on lathe base, be fixedly connected on bottom workbench on the slide block of straight-line rolling guide set, make workbench can with slide block sliding motion on linear rolling track, but the guide rail of straight-line rolling guide set is not reworkable use upon wear, cause the wasting of resources, the guide rail self structure more complicated of hydrostatic slideway pair in addition, need increase a set of
oil supply system, can require higher to assembler, make cost higher.
Utility model content
There is above-mentioned defect in the guide rail that the purpose of this utility model is intended to overcome existing outer surface grinding machine upper feeding mechanism, provides a kind of structure simple, easy for installation and can reprocess the combination roller guide structure of use.
For this reason, the utility model is by the following technical solutions: a kind of combination roller guide structure, comprise left rail mechanism and right guide rail mechanism, workbench is slidably mounted on lathe base by left rail mechanism and right guide rail mechanism, left rail mechanism and right guide rail mechanism comprise two groups of roller guide assemblies respectively, often organize roller guide assembly and comprise the first guide rail, second guide rail and some needle rollers, one side of the first guide rail is provided with the v-depression along the first rail axis direction, one side of the second guide rail is provided with the V-arrangement corresponding with described v-depression protruding, V-arrangement projection is flush-mounted in described v-depression, described some needle roller proper alignment are arranged between the surface of v-depression face and V-arrangement projection, make can mutually slide under the rolling of needle roller between the first guide rail and the second guide rail, on two the second guide rails of described left rail mechanism, relative side protruding with V-arrangement contacts with each other, make the protruding opposing setting of V-arrangement and be all fixedly connected with by screw with lathe base left part end face, two the first guide rails of described left rail mechanism all cooperatively interact with described two the second guide rails and are fixedly connected with bottom workbench, the first guide rail be positioned at outside left end is laterally locked by left holding screw and can finely tune the linearity of guide rail, described lathe base right part end face is provided with positioning convex, on two the second guide rails of described right guide rail mechanism, relative side protruding with V-arrangement is closely posted by two vertical sides of described positioning convex respectively, make the protruding opposing setting of the V-arrangement of these two the second guide rails and be fixedly connected with by screw with described lathe base right part end face, two the first guide rails of described left rail mechanism lay respectively at the both sides of these two the second guide rails and this two the second guide rails cooperatively interact, two the first guide rails are all fixedly connected with workbench, the first guide rail being positioned at outside is laterally locked by right holding screw and can finely tune the linearity of guide rail.
The utility model can reach following beneficial effect: by arranging positioning convex on lathe base, for the locating surface that guide assembly is installed, improves the linearity of guide rail, and improves guide rail rigidity; And the screw that is fitted through of each guide rail is installed fixing, can pull down reparation after making way rub; Overall guide assembly structure is simple, low to assembler's skill set requirements, simple to operate, and easily grasps.
Accompanying drawing explanation
Fig. 1 is the utility model generalized section.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
As shown in Figure 1, the utility model comprises left rail mechanism and right guide rail mechanism, workbench 2 is slidably mounted on lathe base 1 by left rail mechanism and right guide rail mechanism, left rail mechanism and right guide rail mechanism comprise two groups of roller guide assemblies respectively, often organize roller guide assembly and comprise the first guide rail, second guide rail and some needle rollers, one side of the first guide rail is provided with the v-depression along the first rail axis direction, one side of the second guide rail is provided with the V-arrangement corresponding with described v-depression protruding, V-arrangement projection is flush-mounted in described v-depression, described some needle roller proper alignment are arranged between the surface of v-depression face and V-arrangement projection, make can mutually slide under the rolling of needle roller between the first guide rail and the second guide rail, on two the second guide rails 7 of described left rail mechanism, relative side protruding with V-arrangement contacts with each other, make the protruding opposing setting of V-arrangement and be all fixedly connected with by screw with lathe base 1 left part end face, two the first guide rails 8 of described left rail mechanism all cooperatively interact with these two the second guide rails 7 and are fixedly connected with bottom workbench 2, the first guide rail 8 be positioned at outside left end is laterally locked by left holding screw 9 and can finely tune the linearity of guide rail, described lathe base 2 right part end face is provided with positioning convex 3, on two the second guide rails 5 of described right guide rail mechanism, relative side protruding with V-arrangement is closely posted by two vertical sides of described positioning convex 3 respectively, make the protruding opposing setting of the V-arrangement of these two the second guide rails 5 and be fixedly connected with by screw with described lathe base 1 right part end face, improve the linearity of guide assembly, two the first guide rails 6 of described left rail mechanism lay respectively at the both sides of these two the second guide rails 5 and these two the second guide rails 5 cooperatively interact, two the first guide rails 6 are all fixedly connected with workbench 2, the first guide rail 6 being positioned at outside is laterally locked by right holding screw 4 and can finely tune the linearity of guide rail.Each screw described passes through after fixing with the assembly technology hole on nylon block capping workbench, prevents metal fillings from falling into fabrication hole.
