Description

High-precision noise-reduction moving slider

Technical Field

The utility model relates to a slider especially is applied to the high accuracy of making an uproar and removes slider of falling on the guide rail.

Background

The sliding block is a commonly used part in a mechanical mechanism, is used for driving the part to move stably and accurately at a high speed, and is commonly used on automatic equipment, the traditional sliding block has high smoothness and parallelism because a retainer is directly contacted and installed with the blank surface of the sliding block, but the blank surface of the sliding block is not processed, and a rolling groove of the sliding block is finely processed, and the traditional plane contacted with the retainer has poor parallelism of the blank surface, so that the parallelism error of about 10-50 threads between the mounting surface of the retainer and the rolling groove can not be avoided, thereby causing that when the sliding block runs, the rolling ball arranged between the retainer and the rolling groove can be continuously driven to extrude the retainer because the parallelism difference exists between the retainer and the rolling groove, not only causing great noise and resistance, but also causing poor precision when the sliding block slides, so that a high-precision product cannot be manufactured with such movement of the slider.

Chinese utility model patent CN 212177666U discloses a wide body guide rail heavily carries linear guide is vice, and the retainer of this kind of slider can not be done with the absolute parallel of rolling groove to can't solve the extrusion and keep the ware, the resistance is big, the noise is big, the low condition of precision.

SUMMERY OF THE UTILITY MODEL

The utility model discloses solve above-mentioned prior art's shortcoming, provide one kind can fall make an uproar, the high accuracy of falling makes an uproar removes the slider high accuracy, satisfied when the slider as the slider, the noise is little, the resistance is little, remove the precision high, satisfy the demand of high-accuracy sharp product production.

The utility model provides a technical scheme that its technical problem adopted: the noise-reduction high-precision moving slider comprises a slider body, wherein a sliding opening is formed in the slider body, rolling grooves are formed in the left side face and the right side face of the sliding opening, retainer mounting surfaces are arranged on the left side face and the right side face of the sliding opening, the retainer mounting surfaces are parallel to the rolling grooves, a retainer is mounted on the retainer mounting surfaces, and a group of balls are mounted between the retainer and the rolling grooves. The sliding opening is used as a channel for installing with the guide rail; the rolling groove is used as a rolling guide groove when the ball rolls; the left side face and the right side face of the sliding opening are provided with retainer mounting faces, the retainer mounting faces are parallel to the rolling grooves and used for mounting the retainer, and the retainer is mounted on the retainer mounting faces and can be absolutely parallel when balls roll, so that the balls are prevented from continuously extruding the retainer to make noise when rolling continuously; the retainer is used for keeping the position of the ball during operation and preventing the ball from falling out of the sliding block; the function of the ball here is to make the slide block present rolling friction on the guide rail, and the frictional resistance is small.

The retainer is further improved, the mounting surface of the retainer is a concave hole, the depth of the mounting surface of the retainer is 10 threads, and a matching block matched with the mounting surface of the retainer is fixed on the retainer. The depth of the concave hole and the mounting surface of the retainer is 10 threads, and the matching block has the effects of reminding the mounting position of the retainer, ensuring that the retainer can be accurately and quickly mounted at a qualified position, and greatly improving the mounting efficiency and the qualified rate of the sliding block.

Further perfection, the two mounting surfaces of the retainer are arranged up and down, and the two matching blocks are matched with the two mounting surfaces of the retainer. The two retainer mounting surfaces are arranged up and down, the two pairing blocks are paired with the two retainer mounting surfaces, and the two retainer mounting surfaces and the two pairing blocks are used for improving the stability of the retainer in the sliding block, improving the mounting precision and greatly improving the speed of one-time mounting success.

The utility model discloses profitable effect is: the utility model has the advantages of ingenious and reasonable structural design, utilize the spout to be used for with the passageway when guide rail installation, utilize the roll groove to be used for the roll guiding groove when the ball rolls, utilize the left and right both sides face of spout all to be equipped with holder installation face, holder installation face is parallel with the roll groove and is used for installing the holder, when the holder is installed on holder installation face and can make the ball roll, absolutely parallel, and then avoid the ball when rolling that does not stop, continuous extrusion holder and noise sound is sent, utilize the holder to carry out position holding when being used for rolling the ball, avoid the ball to fall out from the slider, utilize the ball to make the slider be rolling friction on the guide rail, frictional resistance is little; the utility model discloses can make holder and rolling groove absolute parallel to make the ball keep absolute parallel not cheap when the operation is rolling, thereby avoid ball and holder often bump and cause that the noise is big, the resistance is big and the running accuracy has the deviation scheduling problem, be worth popularizing and applying.
