Self-centering low-resistance linear guide device

Technical Field

The utility model relates to a straight line guider, specifically speaking are from centering formula low resistance straight line guider.

Background

In various guide rails adopted by a stereo garage product on the market at present, no matter the guide rails are rectangular groove rails or T-shaped rails, guide wheels are not deviated to the left side or the right side of the rails during operation, the guide precision is limited, lateral friction force between the guide wheels and the rails during operation exists all the time, great noise can be generated during operation, and the operation resistance is great. In order to solve the problems, the inventor designs a ball sliding pair adopting a triangular track, and realizes an automatic centering effect through the matching of balls and the triangular track, so that the guiding precision is effectively improved. However, the inventor finds that in practical use, the ball still has large friction resistance between the ball and the mounting seat where the ball is located when rolling.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a from centering formula low resistance straight line guider, it can effectively reduce the vice frictional resistance that has the ball slip, effectively reduces the running resistance on guaranteeing the accurate basis of linear motion direction.

The utility model discloses a realize above-mentioned purpose, realize through following technical scheme: including track and the guide holder by the angle steel preparation, set up the recess on the guide holder, installation guide ball in the recess, guide ball can contact with two inboard inclined planes of orbital angle steel simultaneously, and the recess is inside to set up a plurality of balls along the recess border, and each ball all contacts with guide ball. The utility model discloses a guide ball of guide base, including orbital angle steel concave surface, the angle steel convex surface of crossbearer corresponds the cooperation with orbital angle steel concave surface, the angle steel concave surface of crossbearer sets up 2 at least through-holes, all installs a guide holder in the angle steel concave surface of each through-hole department, the direction ball of each guide holder pass and contact with two inboard inclined planes of orbital angle steel from the through-hole department that corresponds separately. The back of the guide seat is provided with a screw hole, the screw hole is communicated with the groove, an adjusting block is arranged in the screw hole, the periphery of the adjusting block is matched with the screw hole through threads, and the end part of the adjusting block is contacted with each ball.

The utility model has the advantages that: the friction resistance of the existing ball sliding pair can be effectively reduced, and the running resistance and the like can be effectively reduced on the basis of ensuring the accurate guiding of the linear motion.

Detailed Description

From well centering low resistance straight line guider include track 102 and guide holder 118 by the angle steel preparation, set up recess 119 on the guide holder 118, installation direction ball 120 in the recess 119, direction ball 120 can simultaneously with two inboard inclined plane contacts of angle steel of track 102, recess 119 is inside sets up a plurality of balls 121 along recess 119 border, each ball 121 all contacts with direction ball 120. During the installation, will the angle steel convex surface of track 102 imbeds ground downwards, makes track 102 top align with ground, install guide holder 118 in year sweep, carry sweep travelling car or other mobile device bottoms, guide ball 120 is located between ball 121 and the track 102 of the recess 119 of guide holder 118, the vertical position and the horizontal position of guide ball 120 are restricted by a plurality of balls 121, guide ball 120 and guide holder 118 are not direct contact, be rolling point contact between guide ball 120 and a plurality of balls 121, consequently the guide ball of current ball sliding pair compares with guide holder direct contact's structure, the utility model discloses a guide ball 120 rolling resistance can reduce by a wide margin. When the mobile device needs to move, the guiding ball 120 rolls along the rail 102 in the guiding seat 118, so as to guide the device. Because the guide ball 120 can not directly contact the bottom end of the track 102 when moving, a part of area for accommodating sundries can be reserved at the bottom end of the track 102, small sundries can not directly influence the operation of the guide ball 120 after falling into the track 102, the cleaning period of the track can be effectively prolonged, the maintenance cost is reduced, the guide ball 120 is in rolling fit with inclined planes on two sides of the track 102, the guide ball can be automatically aligned to the central position under the action of gravity, compared with the existing track structure, the noise and the resistance during operation can be effectively reduced.

The utility model discloses a stability when lifting means removes can angle steel concave surface one side of track 102 sets up crossbearer 117, and crossbearer 117 also is made by the angle steel, and the angle steel convex surface of crossbearer 117 corresponds the cooperation with track 102's angle steel concave surface, and 2 at least through-holes 122 are seted up to crossbearer 117's angle steel department of bending, all installs a guide holder 118 in the angle steel concave surface of each through-hole 122 department, and the direction ball 120 of each guide holder 118 passes and contacts with two inboard inclined planes of track 102's angle steel from the through-hole 122 that corresponds separately. The structure can operate only by leaving a small fit clearance between the cross frame 117 and the track 102, further enhances the stability of the equipment during movement, and can still ensure that the cross frame 117 cannot be separated from the track 102 when the guide ball 120 is accidentally broken or falls off, thereby preventing the equipment from toppling over.

The utility model discloses a clearance between adjusting device and track 102 can screw 123 is seted up at the guide holder 118 back, and screw 123 communicates with each other with recess 119, and installation adjusting block 124 in the screw 123, adjusting block 124 periphery pass through screw and screw 123 cooperation, and adjusting block 124 tip and each ball 121 contact. When the gap needs to be adjusted, the adjustment can be performed by rotating the adjustment block 124.
