Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The embodiment discloses a guide bearing demolition tool, as shown in fig. 1-4, including threaded rod 1, uide bushing 2, drive nut 3, uide bushing 2 is pegged graft in drive nut 3 bottom, be equipped with ring channel 31 on the 3 bottom of drive nut, install 7 joints of jump ring in ring channel 31 at 2 inner walls of uide bushing, prevent that uide bushing 2 from droing, be equipped with on the face of being connected of drive nut 3 and uide bushing 2 and keep off lid 32 spacing to uide bushing 2, the joint has flat bearing 8 in keeping off lid 32, can rotate for drive nut 3 when making uide bushing 2 fixed, be equipped with anti-skidding line on keeping off lid 32. The transmission nut 3 is in transmission fit with a lead screw of the threaded rod 1, an adjusting shaft 4 which is integrally formed is arranged at one end part of the threaded rod 1, a hexagonal convex block 11 is convexly arranged at one end part of the threaded rod 1 which is far away from the adjusting shaft 4, a gap 5 is arranged on the adjusting shaft 4 to divide the shaft body of the adjusting shaft 4 into a first side arm 41 and a second side arm 42 which are symmetrically arranged left and right, wherein the first side arm 41 is in threaded connection with an adjusting screw 6, the adjusting screw 6 passes through the first side arm 41 and can be abutted against the inner wall of the second side arm 42 to realize the opening of the first side arm 41 and the second side arm 42, a fixing block 43 which is clamped on the inner wall of the guide bearing when the first side arm 41 and the second side arm 42 are opened is convexly arranged at the end part, the adjusting shaft 4 is positioned in the guide sleeve 2 and can axially extend and retract relative to the, the adjusting screw 6 passes through the guide groove 21 and is arranged outside the guide sleeve 2 in a protruding mode.

In the practical use process, when the guide bearing is dismounted, the guide sleeve 2 props against the end face of the guide bearing to extend the fixing block 43 into the guide bearing hole, then the adjusting screw 6 is screwed in by rotating, the screwed adjusting screw 6 slowly props into the first side arm 41, while the force exerted by the fixing of the threaded connection when the adjusting screw 6 is screwed in pushes the first 41 and second 42 side arms apart, so that the fixing block 43 is also stretched and firmly attached to the inner wall of the guide bearing, the situation that the fixing block 43 is elastically retracted and separated from the inner wall of the guide bearing due to pressure is avoided, then, the transmission nut 3 is rotated to drive the threaded rod 1 to move upwards so as to drive the fixing block 43 to move upwards to enable the guide bearing to be separated, and then the adjusting screw 6 is unscrewed to release the opening state of the first side arm 41 and the second side arm 42, so that the fixing block 43 returns to the original position and is separated from the inner wall, and then the fixing block 43 moves out of the inner wall of the guide bearing. The operation in the period is stably performed.

The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, any modification, equivalent replacement, or improvement made within the design concept of the present invention should be included within the protection scope of the present invention.
