Abstract
The invention relates to a slider block combination for linear slide rail that include slider block body, end shield, and ball keeping machine. The feature of the invention is the ball keeping machine need not locked by screw and can be fixed by block structure. Not only the two ends of the ball keeping machine supply support, but also the support structure is designed on the ball keeping machine to enhance the geometry intension to avoid distortion.
Description
Technical field
The invention relates to a kind of slide block combination of linear slide rail, linear slide rail is generally the linear guide mechanism that accurate control is provided, and is widely used on automation equipment, industrial machine, manipulator, machinery industry, measurement machine and the electronic equipment.
Technical background
Linear guiding mechanism all is installed on the general board, and linear slide rail is a kind of linear guiding mechanism, and the combination of the slide block of conventional linear slide rail, as shown in Figure 6, mainly the institutes such as end cap 80 that refluxed by slide block 50 and confession ball form.The retaining member that wherein ball is remained on the slide block 50 is maintenance steel disc 60, and maintenance steel disc 60 is to use the restriction ball outside the contact ball to drop outward.But keep steel disc 60 to utilize screw 70 lockings on slide block 50, so must on slide block 50, be drilled with screw hole 51, and in keeping establishing through hole 61 on the steel disc 60, make screw 70 pass the through hole 61 that keeps steel disc 60 then, and in the screw hole 51 of screw lock on slide block 50, will keep steel disc 60 to be fixed on the slide block 50.
This traditional slide block combination utilizes screw 70 screw locks to keep steel disc 60, keeps steel disc 60 to have enough screw lock constant intensities for making, so generally all use metallic material to form through the mode manufacturing of punching press and bending and molding; But the maintenance steel disc 60 and the ball friction of metallic material are easy to generate noise, and significantly reduced in the life-span of ball, and because of the precision reproducibility of punching press and bending and molding relatively poor, so keep keeping on the steel disc 60 the maintenance curved surface 62 of ball to be not easy moulding and precision is wayward, easily produce and interfere.Moreover when slide block 50 specifications are big, keep the slenderness ratio of steel disc 60 to differ greatly, cause keeping steel disc 60 stage casings to be easy to generate diastrophic phenomenon.
Moreover the slide block 50 that conventional sliders makes up needs the extra processing procedure that increases by one tapping with formation screw hole 51, thus can relatively increase cost of processing, and fix maintenance steel disc 60 with screw 70, the situation that keeps steel disc 60 to be out of shape takes place easily.When the assembly crewman was repeating dismounting and keeps steel disc 60, the action of rotation lock screw was quite wasted time and energy, and is the reason that influences efficiency of assembling in addition.
In sum, the slide block combination of above-mentioned conventional art keeps 70 lockings of steel disc 60 mat screws on slide block 50, except increasing processing and assembly cost, and be easy to generate noise and interfere probability, the life-span of ball is significantly reduced, because of the slenderness ratio that keeps steel disc 60 differs greatly, make to keep steel disc 60 stage casings to be easy to generate diastrophic phenomenon necessity that historical facts or anecdotes has improvement to progress greatly again.
Summary of the invention
The purpose of the slide block combination of linear slide rail of the present invention is to provide a kind of fixing ball retaining member of screw of exempting from, and can reach dismounting easy and saving processing cost and built-up time etc., more can increase ball retaining member geometry intensity and avoid metaboly to produce.
For reaching above-mentioned goal of the invention, the technical solution used in the present invention is as follows:
A kind of slide block combination of linear slide rail has ball to roll in it, this slide block combination comprises at least: a slide block body has the rotatable groove of above-mentioned ball in it; One end cap is arranged at the two ends of above-mentioned slide block body, provide above-mentioned ball to reflux and make Infinite Cyclic, and end cap is provided with draw-in groove; One ball distance ring, two ends are formed with the card key, it is fixing to get to cooperatively interact with the draw-in groove of above-mentioned end cap, and set up an extension part in the ball distance ring stage casing, and establishing positioning bolt on the extension part cooperates with the bottom of above-mentioned slide block body, to promote the whole geometry intensity of ball distance ring, avoid producing diastrophic phenomenon and above-mentioned ball is remained on the above-mentioned slide block body.
The slide block combination of this linear slide rail wherein has an overhead kick structure in the draw-in groove of end cap.
The combination of the slide block of this linear slide rail, wherein the card key at ball distance ring two ends slightly is and colludes shape.
The ball retaining member of the slide block of this linear slide rail combination is improved to the fixed structure of no screw by the fixed structure that screw is arranged; This ball retaining member need not to use screw locking, only needs can be fixed in slide block makes up by cooperating with end cap, ball can't be dropped outward and firmly remains on the slide block body; And adopt dismounting to be easy to the groove-fastening type structure in the position of ball retaining member and end cap combination with one another, so this ball holding device possesses and has disassembly and assembly to be easy to function, the efficiency of assembling that makes up with the slide block that improves linear slide rail.And,, the slide block combination processing cost and the built-up time of linear slide rail are relatively reduced so do not need the additional processing screw hole on the slide block because of not using the screw locking.
Secondly, the present invention considers the slide block combination of long size linear slide rail, and the slenderness ratio of this ball retaining member is big, is easy to generate diastrophic phenomenon.Therefore ball retaining member of the present invention can provide support the power except two ends, designs the structure of the power that can provide support in addition on the ball retaining member, can increase ball retaining member geometry intensity and avoid metaboly to produce.
In addition, ball retaining member of the present invention also can be improved to and adopt the plastics injection molding, not only can improve metal collision friction produced each other noise and life problems, more can reduce the whole manufacture cost and the uppity shortcoming of precision of linear slide rail.
Further understand feature of the present invention and technology contents for convenience, please consult following relevant embodiments of the present invention in detail, however this mode of execution and graphic only for explanation and with reference to usefulness, rather than be used for the present invention is done any restriction.
Use beneficial effect of the present invention to be: because of not using the screw locking, so do not need the additional processing screw hole on the slide block, can make the slide block combination dismounting of linear slide rail easy, processing cost and built-up time relatively reduce; The ball retaining member can provide support the power except two ends, designs the structure of the power that can provide support in addition on the ball retaining member, can increase ball retaining member geometry intensity and avoid metaboly to produce; The ball retaining member is improved to and adopts the plastics injection molding, not only can improve metal collision friction produced each other noise and life problems, more can reduce the whole manufacture cost and the uppity shortcoming of precision of linear slide rail.
