Abstract
The invention relates to a linear guide rail, and particularly relates to a retainer and a linear guide rail sliding block. By adopting an optimizing structure of the retainer of a linear guide rail device, provided by the invention, balls can be easily arranged in the linear guide rail sliding block, and when the balls fall out of the retainer, the retainer can be easily filled up with balls, so that the production efficiency is improved. The retainer comprises two rotary guide parts and two longitudinal guide parts, wherein rotary grooves are formed in the rotary guide parts which are located at the two ends of the longitudinal guide parts, ball filling notches are formed in the longitudinal guide parts, and the opening distance of each ball filling notch is less than but not more than 0.9 times of the diameter of the ball. Due to the adoption of the technical scheme, the assembly technological process of the linear guide rail is improved, the assembly speed of the linear guide rail sliding block can be accelerated, and after other accessories are assembled, the balls are arranged in the sliding block from the ball filling notches, so that the production efficiency can be greatly improved.
Description
Technical field
The present invention relates to a kind of linear rail, specifically, relate to a kind of retainer and straight-line guide rail slide block.
Background technique
Original retainer generally all comprises two revolution guide portions, two longitudinal guide portions, revolution guide portion arranges turning slot, revolution guide portion is positioned at the two ends of longitudinal guide portion, ball is in the revolution of the position of turning slot, the circular arc size of turning slot is determined according to the gap between slide block and slide rail, guaranteeing that ball moving is smoothly under prerequisite, make the coated portion of retainer as far as possible large, can well maintain ball like this, there is good retentivity, if but under special status, ball is subject to external force and drops out outside retainer, be difficult to be filled up, as shown in Figure 1, benefit pearl process of the prior art is such, other accessories on slide block must be pulled down just and can be filled up ball like this, efficiency is very low.
Summary of the invention
Main purpose of the present invention is to overcome the structural not enough defect of existing retainer, the retainer that proposes a kind of linear guide rail device is optimized structure, and makes existing straight-line guide rail slide block easily assemble ball, and when ball drops out this retainer, can easily fill up this ball, to enhance productivity.
The technological scheme of retainer of the present invention is such: it comprises two revolution guide portions, two longitudinal guide portions, revolution guide portion arranges turning slot, revolution guide portion is positioned at the two ends of longitudinal guide portion, longitudinally on guide portion, arrange and mend pearl breach, but the extended distance of mending pearl breach is set to be less than and is not more than 0.9 times of ball diameter.
Optimally, the length of breach is greater than the diameter that 1 ball diameter is not more than 4 balls.
The technological scheme of straight-line guide rail slide block of the present invention is such: it comprises retainer, retainer comprises two revolution guide portions, two longitudinal guide portions, revolution guide portion arranges turning slot, revolution guide portion is positioned at the two ends of longitudinal guide portion, longitudinally on guide portion, arrange and mend pearl breach, but the extended distance of mending pearl breach is set to be less than and is not more than 0.9 times of ball diameter.
Optimally, the diameter that the length of breach is greater than 1 ball is not more than the diameter of 4 balls.
Gap position should be arranged on the neutral position of the coated portion of retainer, and the length of breach is advisable in the size of the rolling element diameter of 1 to 4 times.
The present invention has following progressive effect, and longitudinal guide portion intermediate portion of this retainer arranges a breach, be difficult for dropping out, and ball while dropping out this retainer under special status, easily supplements ball with ball convenient for assembly and ball.
The technical program and improved the assemble flow of linear rail, the technological scheme of this explanation can be accelerated the assembling speed of straight-line guide rail slide block, after other accessories can being assembled, then from mending pearl breach, packs ball into slide block, can greatly enhance productivity.

Embodiment
Embodiment 1:
As shown in Fig. 2,3,4,5, it comprises retainer the straight-line guide rail slide block of the present embodiment, retainer comprises two revolution guide portions 1, two longitudinal guide portions 2, revolution guide portion 1 arranges turning slot, revolution guide portion 1 is positioned at the two ends of longitudinal guide portion 2, longitudinally on guide portion 2, arrange and mend pearl breach 3, the extended distance of mending pearl breach 3 is set to 0.9 times of ball diameter.The length of breach is set to the size of 1 ball diameter.
The straight-line guide rail slide block of the technical program comprises end cap 4 and retainer and the slide rail 7 at slide block body 6 and two ends, on longitudinal guide portion 2 of retainer, arrange and mend pearl breach 3, but the extended distance of mending pearl breach 3 is set to be less than ball 5 diameters 0.9 times of being not more than ball diameter.The coated portion of longitudinal guide portion 9 edges of retainer are D(Fig. 5 to the distance at boss 8 places of slide block intermediate portion), the diameter of definition ball 5 is D1, through overtesting, draw, when D>=D1, the coated portion 9 of retainer can not maintain ball, and ball 5 drops out retainer at an easy rate; When D<0.9D1, the coated portion 9 of retainer can maintain ball 5 well, but want to fill up ball, becomes relatively difficult; When 0.9D1<=D<D1, the coated portion of retainer both can maintain ball well, can when ball is installed, from indentation, there, fill up into again, had improved packaging efficiency.
Embodiment 2:
The present embodiment and embodiment's 1 difference is, mends pearl breach apart from 0.95 times that is set to ball diameter, and the length of breach is set to the size of the diameter of 3 balls.
Embodiment 3:
The present embodiment and embodiment's 1 difference is, mends pearl breach apart from 0.96 times that is set to ball diameter, and the length of breach is set to the size of 4 ball diameters.
The foregoing is only the preferred embodiment of the present invention, protection scope of the present invention is not limited in above-mentioned mode of execution, and every technological scheme that belongs to the principle of the invention all belongs to protection scope of the present invention.For a person skilled in the art, some improvement or the retouching under the prerequisite that does not depart from principle of the present invention, carried out, these improvements and modifications also should be considered as protection scope of the present invention.
