Abstract

The utility model discloses a bearing removing device, which comprises a disc block (1), a cylinder (2), a main shaft core (3) and screws (4), wherein a cavity for accommodating a bearing is arranged in the disc block (1); the screw (4) is movably connected with the disc block (1) through threads; the spindle core (3) comprises a dismantling end for dismantling the bearing and an operating end for rotating the spindle core (3); the cylinder (2) is sleeved and fixed on the dismantling end of the spindle core (3). The scheme can cause appropriate deformation on the outer circumference of the bearing to remove the flanging, reduces the maximum diameter of the bearing, reduces the blocking between the bearing and the machine body, can take the bearing out of the machine without damaging the main body of the machine part, avoids the damage of the dismantling work of the bearing to the main body of the machine part, and ensures that the disassembly work of the machine part can be completed.

Description

Bearing removing device

Technical Field

The utility model relates to a bearing frock field especially relates to a bearing demolishs device.

Background

The bearing puller is a common tool for bearing disassembly, the existing bearing puller is generally a tripod puller, and a three-jaw puller is a tool frequently used in mechanical maintenance. Mainly for axially removing damaged bearings from the shaft. Mainly comprises a rotating handle, a screw rod and a pulling claw. The bearing has two claws and three claws, and the main sizes are the length of the pulling claw, the distance between the pulling claws and the length of the screw rod so as to adapt to bearings with different diameters and different axial installation depths. When the device is used, the screw rod tip is positioned in the shaft end tip hole to adjust the position of the pull claw, so that the pull claw is hooked on the outer ring of the bearing, and the pull claw drives the bearing to move outwards along the axial direction to be dismounted by rotating the rotating handle. Because the position of the three feet of colluding of tripod draws the horse hardly fixes, therefore the practicality of tripod draws the horse and is inconvenient, what current bearing draw the horse generally adopted hooks the outer lane of bearing with the foot and dismantles, because the foot is less with bearing inner race contact surface, therefore the foot very easily slips the bearing inner race, and very easily damages parts main part and fitting surface, and the manual work is demolishd inefficiently.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art's is not enough, provides a bearing demolishs device, can cause suitable deformation to get rid of the turn-ups and do not harm parts main part outside the bearing, reduces the biggest external diameter of bearing, reduces the card between bearing and organism and hinders to the bearing can be under the prerequisite of not fish tail parts fitting surface, demolishs from the parts.

The purpose of the utility model is realized through the following technical scheme:

a bearing dismounting device comprises a disc block, a cylinder, a main shaft core and a screw, wherein a cavity for accommodating a bearing is formed in the disc block; the screw is movably connected with the disc block through threads; the main shaft core comprises a dismantling end for dismantling the bearing and an operating end for rotating the main shaft core; the cylinder is sleeved and fixed on the dismantling end of the spindle core.

Optionally, a blade is arranged at a gap between the inner wall of the cavity of the disc block and the thread;

alternatively, the screw fastens the bearing by rotating the pressing blade.

Optionally, the device further comprises a servo motor, and a rotating bearing of the servo motor is fixedly connected with the operating end of the spindle core.

The utility model has the advantages that: according to the scheme, the bearing can be appropriately deformed at the outer circumference of the bearing to remove the flanging, the maximum diameter of the bearing is reduced, the blocking between the bearing and the machine body is reduced, the bearing can be taken out of the machine and does not damage the main body of the machine part, the damage of the dismantling work of the bearing to the main body of the machine part is avoided, and the disassembly work of the machine part can be completed.

Detailed Description

In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings.

In this embodiment, as shown in fig. 1 to 6, a bearing removing device includes a disk block 1, a cylinder 2, a spindle core 3 and a screw 4, a cavity for accommodating a bearing is provided inside the disk block 1, the screw 4 is movably connected with the disk block 1 through a thread, the spindle core 3 includes a removing end for removing the bearing and an operation end for rotating the spindle core 3, and the cylinder 2 is sleeved and fixed on the removing end of the spindle core 3.

Optionally, a blade is arranged at a gap between the inner wall of the cavity of the disc block 1 and the thread.

Alternatively, the screw 4 fastens the bearing by rotating the pressing blade.

Optionally, the spindle device further comprises a servo motor, and a rotating bearing of the servo motor is fixedly connected with the operating end of the spindle core 3.

In this embodiment, a bearing demolishs the theory of operation of device does: firstly, a blade is installed at the gap of the top end of the screw 4, the screw 4 is screwed down to fix the blade, a bearing sleeve to be disassembled is sleeved outside the cylinder 2, a flanging surface to be processed faces the disc block 1, and the distance between the main shaft core 3 and the disc block 1 is reduced by rotating the main shaft core. When the blade on the disk block 1 contacts the bearing, the disk block 1 is slowly rotated to wear the flange of the bearing to a proper thickness. And then the disc block 1 and the main shaft core 3 are separated by reverse rotation, the tool is dismounted from the machine part, and the press machine can be used for dismounting the bearing without damaging the main body of the machine part. The spindle core 3 can be driven to rotate by a servo motor.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
