Description

Slider structure and grinding method thereof

The present invention relates to a slider for use with a slide rail, and more particularly to the structure of the slider.

Referring to Figure 1, the linear slide can provide relative linear freedom of movement. It usually includes a slide rail (not shown) and a slider 1 for the slide rail. The slider includes a slider. The body 2 is provided with a linear guide groove 3, and the linear guide groove 3 defines an opening 4 at each end of the base body 2, and the linear guide groove 3 is ground by using a grinding wheel 5.

Please also refer to FIG. 2A and FIG. 2B. The grinding wheel 5 reciprocates along the linear movement path 6 on the base body 2, thereby forming the linear guide groove 3 by grinding, and in order to make the sliding The rails can smoothly enter the linear guide groove 3, and the grinding wheel 5 will be adjacent to the two openings 4 on both sides of the linear guide groove 3, along the four-point angle path 7, and the four-conductance angle 8 is ground to The entrance size of the two openings 4 is enlarged by the presence of the four guide angles 8 to allow the slide rail to smoothly slide into the linear guide groove 3.

The structure of the slider 1 and the polishing method thereof can smoothly slide the slide rail into the linear guide groove 3, but the smooth contact between the four guide angles 8 and the linear guide groove 3 is not smooth. The surface, that is, the four guide angles 8 and the surface of the linear guide groove 3, may have an uneven angle (cross-section difference), so that when the slide rail enters the linear guide groove 3, there is a tendency to jump vibration. Further, the presence of the four lead angles 8 causes the length of the linear region 9 of the linear guide groove 3 to be shortened. Therefore, balls (not shown) are disposed in the linear guide groove 3, and balls which are not disposed in the linear region 9 are not effective. Bilateral contact with the slide rail, when the ball that effectively contacts the slide rail is reduced, when the slider 1 slides relative to the slide rail, there is a phenomenon that the jam is unsatisfactory, and the service life is shortened, which is easy after long-term use. There are noise and vibration problems that cannot meet the need for smoothness.

The main object of the present invention is to disclose a slider structure which can increase the smoothness of sliding.

A secondary object of the present invention is to disclose a slider polishing method that can increase the smoothness of sliding.

In order to achieve the above object, the present invention discloses a slider structure and a polishing method thereof, wherein the slider structure has a body, and the base body is provided with a linear guide groove, and the linear guide groove is respectively formed at two ends of the base body. The opening, the two sides of the linear guide groove and the two openings form a four-arc edge, and the tangential direction of the connection between the arc-shaped side and the linear guide groove respectively overlaps the edge of the linear guide groove.

The grinding method of the present invention firstly grinds the linear guide groove by using a grinding wheel, and then uses the same grinding wheel to connect the two openings on both sides of the linear guide groove, and respectively moves in a circular arc shape. The arc edges are ground in a manner, and the grinding wheel is in a one-way moving stroke, and the side edges of the linear guide grooves and the arc edges on the same side are simultaneously ground.

As can be seen from the above description, the present invention has the following features as compared with the prior art:

a design in which the arc-shaped sides are respectively disposed between the two sides of the linear guide groove and the two openings, and the tangent lines at the junctions of the arc-shaped sides and the linear guide groove respectively overlap the linear guide groove, It can avoid the uneven section difference, and can effectively increase the linear length of the linear guide groove, so that the ball that effectively contacts the slide rail can be increased, not only can avoid the vibration generated during the slip, and the slide rail can smoothly slide into the linearity. The guide groove can increase the life while satisfying the requirement of sliding fluency.

2. In order to use the same grinding wheel to connect the two openings on both sides of the linear guide groove, the arc edges are respectively moved to grind out the arc edges, so the arc edges and the surface of the linear channel Consistent features for increased smoothness while moving.

3. Let the grinding wheel grind the arc edges on the same side of the linear guide groove in a one-way moving stroke, thereby increasing the same direction, and further increasing the smoothness during the movement.

The detailed description and technical contents of the present invention will now be described with reference to the following figures: Referring to FIG. 3A and FIG. 3B, the slider structure of the present invention includes a body 10, which is a body. A linear guide groove 11 is formed. The linear guide groove 11 defines an opening 12 at each end of the base body 10, and a four-arc edge 13 is formed between the two sides of the linear guide groove 11 and the two openings 12, And the tangential direction of the connection between the circular arc edge 13 and the linear guide groove 11 overlaps the edge of the linear guide groove 11, respectively.

Moreover, the linear guide groove 11 can be a common dovetail groove shape, or can be other shapes according to various application requirements, and the four circular arc edges 13 have the same curvature for convenience in manufacturing and use. It is a preferred embodiment.

In the polishing method of the slider structure of the present invention, first, the linear guide groove 11 is ground on the base body 10 by using a grinding wheel 20. Then, using the same grinding wheel 20 to connect the two openings 12 on both sides of the linear guide groove 11, the arc edges 13 are ground in a circular arc shape, and Referring to FIG. 4 together, in order to increase the stability during slipping, the grinding wheel 20 is in a one-way moving stroke 31, 32 while grinding the sides of the linear guide groove 11 and the same side. The arc edge 13, that is, the grinding wheel 20, during the grinding process, simultaneously grinds the side edges of the linear guide groove 11 and the arc edges 13 on the same side, thereby increasing the stability during slippage.

In addition, the grinding wheel 20 can reciprocate a plurality of linear movement paths 30 on the base body 10 to gradually grind out the linear guide groove 11 , and the arc edges 13 have the same curvature to increase manufacturing and use. Convenience.

In summary, the present invention has the following features as compared with the prior art:
