Abstract
The utility model discloses a combined returner which comprises a returner body with screw fixing holes and a guide rail groove, and a positioning piece, wherein two convex semi-circular hole grooves are arranged on the returner body, and two convex semi-circular hole parts are arranged on the positioning piece; the semi-circular hole grooves and the semi-circular hole parts are arranged at the two sides of the guide rail groove, and the positioning piece is arranged on the returner body; and the semi-circular hole parts and the semi-circular hole grooves are combined into convex full circular return positioning holes. According to the combined returner, the return positioning holes are combined by the two convex semi-circles, the structure is simple and reasonable, and the installation is convenient; in installation, the convex full circular holes are matched with the screw holes to allow the returner to be positioned on a sliding block, so that the positioning error of the returner and the sliding block is reduced, the installation efficiency and the yield are improved, the accuracy rate of running and the smoothness of running of steel balls are further guaranteed, and the practical effect is good.
Description
Technical field
The utility model belongs to the linear rail field, is specifically related to a kind of combined type back device that is used on the linear rail.
Background technique
The back device is one of critical piece of linear rail, carries out back through the back device when it act as the steel ball operation, so the steel ball function smoothly does not depend on the back device smoothly to a certain extent yet; Existing back device mainly is made up of back device body and locator; When assembling, need put into the back hole to locator with tweezers, there is certain deficiency in it, and is complicated like assembly technology; Be not easy assembling; And deviation being arranged through locating the back hole that also can cause in the back device and the back hole in the slide block in the screw fixed hole, steel ball operation accuracy rate is low, causes operation to have some setbacks.
Summary of the invention
The purpose of the utility model provides simple and reasonable, easily a kind of combined type back device of assembling.
The technological scheme that realizes the utility model purpose is a kind of combined type back device; Comprise the back device body, the location piece that are provided with screw fixed hole and guide rail groove; Said back device body is provided with the semicircle hole slot of two convexities, and said location piece is provided with the semicircle orifice portion of two convexities, and said semicircle hole slot and semicircle orifice portion are arranged on the both sides of guide rail groove; Said location piece is installed on the back device body, and semicircle orifice portion and semicircle hole slot are combined into protruding full circle back positioning hole.
Further, the semi-circle of said two semicircle hole slots is oppositely arranged, and the semi-circle of said two semicircle orifice portions is provided with in opposite directions.
The utlity model has positive effect: the back hole of the utility model is that the semicircle by two convexities combines, and is simple and reasonable, easy for installation; Can cooperate screw hole that the back device is positioned on the slide block by the full circle hole of convexity during installation; Reduce back device and slide block positioning error, improved installation efficiency and yield, further guaranteed the accuracy rate of steel ball operation; And the smoothness of operation, good practical effect.
Description of drawings
For the content that makes the utility model is more clearly understood, below according to specific embodiment and combine accompanying drawing, the utility model is done further detailed explanation, wherein:
Fig. 1 is the composite structure schematic representation of the utility model;
Fig. 2 is the back device body structure schematic representation of combined type back device shown in Figure 1;
Fig. 3 is the location piece structural representation of combined type back device shown in Figure 1.
Reference character: screw fixed hole 1, guide rail groove 2, back device body 3, location piece 4, semicircle return groove 31, semicircle orifice portion 41, full circle back positioning hole 5.
Embodiment
(embodiment 1)
Fig. 1 to Fig. 3 has shown a kind of embodiment of the utility model, and wherein Fig. 1 is the composite structure schematic representation of the utility model; Fig. 2 is the back device body structure schematic representation of combined type back device shown in Figure 1; Fig. 3 is the location piece structural representation of combined type back device shown in Figure 1.
See Fig. 1 to Fig. 3; A kind of combined type back device comprises the back device body 3, the location piece 4 that are provided with screw fixed hole 1 and guide rail groove 2, and back device body 3 is provided with the semicircle hole slot 31 of two convexities; Location piece 4 is provided with the semicircle orifice portion 41 of two convexities; Semicircle hole slot 31 and semicircle orifice portion 41 are arranged on the both sides of guide rail groove 2, and location piece 4 is installed on the back device body 3, and semicircle orifice portion 41 is combined into protruding full circle back positioning hole 5 with semicircle hole slot 31.During assembling, only need the screens sheet be placed on the back device body, screw fixed hole is consistent places for it; Its semicircle orifice portion cooperates the full circle hole of forming a convexity with the semicircle hole slot, can cooperated screw hole to make to device by the full circle hole of convexity during installation and be positioned on the slide block, has reduced back device and slide block positioning error; Installation efficiency and yield have been improved; Further guaranteed the accuracy rate of steel ball operation, and the smoothness of operation, good practical effect.
The semi-circle of two semicircle back hole slots is oppositely arranged, and the semi-circle of two semicircle back hole portions is provided with in opposite directions.
Obviously, the foregoing description of the utility model only be for explain clearly that the utility model does for example, and be not to be qualification to the mode of execution of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all mode of executions.And conspicuous variation that these connotations that belong to the utility model are extended out or change still belong to the protection domain of the utility model.
