Abstract

The invention relates to a universal bearing puller, which is a bearing puller manufactured by self in the past, wherein bearing tools are searched by watching small videos on the internet and panning the small videos and combining the tools together through thinking, the universal bearing puller can be used for pulling bearings of various sizes inside and outside by supporting a main body thick steel plate, a top screw rod, four long screw rods, a free impact heavy steel block, a welded steel bar frame, a screw nut and the like.

Description

Universal bearing puller

Technical Field

The invention relates to a universal bearing puller.

Background

The invention relates to a universal bearing puller, which is a bearing puller which is self-made in the past, and is used for looking at a small video on the internet and searching for a bearing tool by panning, so that the universal bearing puller which does not really pull up an inner bearing and an outer bearing simultaneously is seen, the universal bearing puller is written by combining the inner bearing and the outer bearing through thinking, and the bearings with various sizes can be pulled up inside and outside; the invention can bring the subjective initiative of people into play, can change automatically, can be applied to more places needing to be pulled up, and is written to the people needing to be pulled up, and hopes that the invention brings convenience to the work and life of the people using the invention.

Disclosure of Invention

The invention relates to a universal bearing puller, which is characterized in that 1, a support main body of the universal bearing puller is a cubic steel plate with the length of 100mm and the width of 12mm, holes are punched, a screw rod 5 is a screw rod screwed into the steel plate 1 and provided with a threaded hole 18, the screw rod 5 is 200mm and is pushed onto a shaft required to push out a bearing, a plane is required to be ground at two sides of a through hole at the front end of the screw rod 5, the screw rod is convenient to insert 13 and screw the screw rod by using a movable wrench at a narrow place, 4 screw holes are arranged on the support main body 1, 4 screws 19 are screwed in, the effect of preventing a steel bar frame welded by 7 from falling off from the steel plate of the support main body is achieved, the other ends of the two steel bar frames welded by 7 are clamped to two sides of an inner ring of the bearing, a movable rotating rod 15 is inserted through two sides of the through hole on the 5 and screwed by using a nut with a cap 3, the screw rod 5 is pushed onto the shaft required to push out the bearing, an external bearing can be pushed out continuously under the applied force, 8 two thin steel plates can be used when the space at the bottom of the bearing can not be placed into the steel bar frame 7, the steel plate can be inserted into the bottom of the bearing, two ends of the steel plate are placed on the inner side of the steel bar frame 7, similarly, 17 are two long steel bars, 16 are two steel plates with corresponding through holes, and the round bars are inserted into the corresponding steel plate through holes and can replace the steel bar frame 7, so that the outer bearings with various sizes can be pulled out; 2 is 4 oblique long flat through holes with width of 6mm and length of 20mm which are arranged on the diagonal line of a steel plate of a support main body 1, 4 oblique long flat through holes which are arranged on the support main body 1 are inserted into 4 long screw rods 9, the upper and lower surfaces of the oblique long flat through holes are respectively screwed by 4 steel pads 6 and 4 nuts 3, the function of fixing the inserted 4 long screw rods 9 is achieved, 9 is a long screw rod with the diameter of 4mm and the depth of 1mm and the width of 20mm grooves which are ground by an angle grinder (9 can be selected by long screw rods with different diameters according to the size of a bearing), 10 is a screw with the bottom of a regular quadrilateral slope which is ground by the angle grinder (10 needs to select screws with different diameters smaller than the bearing according to the size of the bearing), the upper surface of the screw is screwed by the steel pads 6 and the nuts 3, the function of fixing the grooves on the 4 long flat screw rods 9 in the inner hole of the bearing without causing the disorder movement is achieved, 13 is a bent steel plate with corresponding through holes which is inserted into the flat through hole end of the 5 top screw rod, the screw-thread steel bars at two ends are inserted into 13 and the through holes on the 5 top screw rods are screwed together by the nuts 3 to play a role of fixing the screw-thread steel bars 13 on 5, 12 is that the screw-thread steel bars at two ends are inserted into the through holes at the left end of 13 and are fixed by 2 nuts 3, 11 is a handle-shaped free heavy steel block inserted into 12, the front end of the free heavy steel block is fixed by 2 nuts 3, the free heavy steel block is continuously impacted on the front end nut by hands (the front end nut can be welded and fixed), force is transmitted to an inner bearing hole through the long screw rod 9, bearings with various sizes can be internally pulled, and the nuts are required to be added at the right end of the 5 top screw rod to prevent the top screw rod from being damaged; thus, the universal bearing extractor is formed.

The attached drawings are as follows:

description of the drawings: FIG. 1 is a front view of the present invention

1 supporting a main body steel plate 2, a nut 4 with a long flat through hole and a steel plate screw 5, a top lead screw 6, a steel pad 7, a steel frame 8, a steel plate 9, a long lead screw 10, a ground square slope screw 11, a free heavy steel block 12, a free heavy steel block 14, a free heavy steel bar 15, a threaded steel bar 13 at two ends of the support body steel plate 1, a steel plate 17, a long steel bar 18, a threaded hole 19, a screw hole 19 and a screw hole 19, wherein the long steel bar 18 corresponds to a steel plate 16 with a through hole and is provided with a through hole

The specific implementation mode is as follows:

the invention relates to a universal bearing puller, which is composed of a thick steel plate serving as a support main body, a top screw rod, four long screw rods, a free impact heavy steel block, a welded steel bar frame, screws, nuts and the like.

Claims

1. The invention relates to a universal bearing extractor, which is a novel structure combination mode of the universal bearing extractor, wherein 4 inclined long flat through holes are formed in a supporting main body, one ends of 4 filament rods are provided with bearing clamping grooves, and a screw 10 is used for grinding a square slope to fix a bearing, so that the universal bearing extractor is different from other bearing extractors.
