Linear slide circulation device with dustproof structure

The present invention relates to a linear slide circulation device having a dustproof structure, in particular to a first dustproof sheet having a length equal to that of a holding member on a holding member, a second dustproof sheet on the end cover, and a second dustproof sheet. The first dustproof sheet is smoothly and smoothly connected in the axial direction of the slide rail, so that the first dustproof sheet and the second dustproof sheet are completely supported by the holding member and the end cover, and the strength is high.

The linear slide rails straddle the slide on the slide rails, and fix the mechanism on the slide seat, and slide the slide rails on the slide rails to achieve the purpose of moving the parts, wherein the linear slide rails have high precision, High smoothness and high stability.

The sliding seat is arranged on the sliding rail to form a closed circulation channel, comprising a track area between the sliding seat and the sliding rail, and two rotating channels are connected to the two ends of the track area on the sliding seat, and the returning channel is further arranged on the sliding seat. The two rotating channels are connected, and the rolling bodies arranged in the row are placed in the circulation channel to circulate, and when the rolling elements enter the track area, one side contacts the sliding rails, and the other side contacts the sliding seat, so that the sliding seat can be driven on the sliding rails shift.

Generally, a circulation component is installed on the sliding seat to maintain the stability of rolling of the rolling element, and the rolling element is guided to advance in the circulation passage. For example, the circulation device is the "circular device for linear slide" of the Republic of China Patent No. M310272. The Republic of China Patent No. M322487 "Rotary Cycle Guide Structure for Linear Slides" and other related cases.

In addition, dust and dirt can not be avoided in the linear slide working environment. In order to prevent dust from entering the circulation channel and affecting the smooth rolling of the rolling elements, dustproof sheets are sometimes installed to block the circulation passage and the external working environment, but the added dustproof sheets are assembled. The difficulty is so that the dustproof sheet is sometimes formed on the circulation device to provide assembly convenience. For example, the Republic of China Patent No. M415218 "Linear Slider with Dust-Resistant Reflow Assembly", except that the dust-proof piece of the previous case extends and protrudes out of the reflow assembly (circulation device), which is usually protruded during assembly. The end of the dust-proof piece is positioned, and the support effect and structural strength of the dust-proof piece are poor, and there is a risk of breakage under the high-speed operation of the sliding seat, and sometimes the artificial assembly process may also break the dustproof piece and increase the loss of the reflow component. rate.

In addition, the above-mentioned previous case does not have the effect of dust-proofing the end of the sliding seat, and the dustproofing of the end of the sliding seat is still an external type. For example, the Republic of China Patent No. M282068 "Circular Device for Linear Slides" is attached to the sliding seat. A dustproof piece is attached to the end caps at both ends.

Therefore, in order to avoid the risk of breakage of the protruding dustproof sheet and further solve the inconvenience of the assembly of the additional dustproof sheet, the present invention proposes a linear slide circulation device having a dustproof structure for being assembled in a The sliding body rigid body provides a closed loop circulation passage for inserting the rows of balls, and when the sliding body rigid body is spanned on a sliding rail, the rigid body of the sliding seat is enabled by rolling in a row of balls The slide rail is linearly reciprocated; wherein the circulation device comprises:

a holding member is disposed on the rigid body of the sliding block. The holding member has an elongated shape extending along the axial direction of the sliding rail. The holding member is provided with a first dustproof piece.

Further, the first dust-proof sheet and the second dust-proof sheet have the same cross-sectional shape, and are connected to each other in such a manner that the cross-sectional contours are aligned with each other.

Further, the first dustproof sheet of the holding component includes a first upper dustproof sheet and a first lower dustproof sheet, and the second dustproof sheet of the end cover includes a second upper dustproof piece and a second lower dustproof piece respectively connected to the The first upper dustproof piece and the first lower dustproof piece are configured to correspondingly shield upper and lower sides of the circulation channel. And preferably, a third dustproof sheet is disposed on the end cover, the third dustproof piece is in contact with the sliding rail or has a slight gap between the sliding rail and the sliding rail for shielding the axial direction of the sliding rail. Loop channel.

Further, the first dustproof sheet is integrally formed on the holding member, and the second dustproof sheet and the third dustproof sheet are integrally formed on the end cover.

The effect of this creation is:

1. The first dustproof sheet and the second dustproof sheet are completely supported by the holding component and the end cover, have high strength, are not easily damaged and broken, and need not be positioned for the first dustproof piece and the second dustproof piece during assembly. .

2. The first dustproof sheet and the second dustproof sheet are shielded from the circulation passage in the axial direction of the slide rail, and the third dustproof sheet is used to shield the circulation passage in the axial direction of the slide rail, thereby effectively blocking dust. Dirtyness enters the circulation channel.

3. The first dustproof sheet integrally formed on the holding member, and the second dustproof sheet and the third dustproof sheet integrally formed on the end cover can improve the convenience of assembly.
