The technical scheme of the utility model is further improved as follows: the included angle of the V-shaped groove is 33-38 degrees.

The technical scheme of the utility model is further improved as follows: the other end of the ejector rod bolt is also provided with a handle, and the handle is perpendicular to the bolt section.

The technical scheme of the utility model is further improved as follows: the nut is an M20 nut.

The technical scheme of the utility model is further improved as follows: the V-shaped groove is internally provided with a shaft, a bearing matched with the shaft is positioned between a shaft support plate and a push rod bolt support plate, and the center of the end face of the shaft is superposed with the center of the end face of the bolt section of the push rod bolt.

Due to the adoption of the technical scheme, the utility model has the following technical effects:

the bearing disassembling device is simple in structure and low in manufacturing cost, the bearing can be disassembled more conveniently, the bearing disassembling device can be operated by one person, time and labor are saved, the bearing can be disassembled without knocking the bearing, the bearing can be protected, and equipment can also be protected.

The V-shaped groove support shaft is arranged, bearings with different diameters can be detached, and the arrangement improves the capability of the tool for adapting to the bearings of different equipment.

The utility model is convenient to use, and the problem that the pull claw is easy to open in use can not be caused.

Drawings

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic perspective view of a removable support of the present invention;

FIG. 3 is a side view of the removable cartridge of the present invention;

the device comprises a connecting plate 1, a connecting plate 2, a push rod bolt supporting plate 2-1, a U-shaped groove 2-2, a baffle plate 3, a shaft supporting plate 3-1, a V-shaped groove 4, a shaft 5, a bearing 6, a push rod bolt 7 and a nut.

Detailed Description

The utility model is described in further detail below with reference to the following figures and specific embodiments:

a bearing detaching tool is shown in figures 1-3: the detachable support comprises a detachable support and an ejector rod bolt 6, wherein the ejector rod bolt 6 comprises a bolt section and a handle, and the bolt section is perpendicular to the handle; the dismounting support comprises a connecting plate 1, and a shaft supporting plate 3 and a mandril bolt supporting plate 2 are respectively arranged at two ends of the connecting plate 1. The shaft supporting plate 3 is provided with a V-shaped groove 3-1, the included angle of the V-shaped groove 3-1 is 33-38 degrees, when the bearing dismounting device is used, a shaft 4 to be subjected to bearing dismounting penetrates through the V-shaped groove 3-1, and a bearing 5 matched with the shaft 4 is positioned between the shaft supporting plate 3 and the ejector rod bolt supporting plate 2. The ejector rod bolt supporting plate 2 is provided with a U-shaped groove 2-1, two sides of the U-shaped groove 2-1 are welded with baffle plates 2-2 of a positioning nut 7, the baffle plates 2-2 can clamp the nut 7 and prevent the nut 7 from rotating, and the nut 7 can horizontally slide between the two baffle plates 2-2; the ejector rod bolt 6 penetrates through the U-shaped groove 2-1 to be matched with the nut 7, and the horizontal position of the ejector rod bolt 6 in the U-shaped groove 2-1 is adjustable. The center lines of the V-shaped groove 3-1 and the U-shaped groove 2-1 are positioned on the same horizontal plane, so that when the bearing is applied, the horizontal positions of the ejector rod bolt 6 and the nut 7 are adjusted to enable the center of the end face of the shaft 4 to be superposed with the center of the end face of the bolt section of the ejector rod bolt 6, and the ejector rod bolt 6 is gradually rotated to disassemble the bearing.
