Description

Technical Field

[0001] This utility model relates to the field of bearing press technology, specifically a motor bearing press. Background Technology

[0002] An electric motor bearing press is a device specifically designed for installing electric motor bearings. Its main function is to precisely install the bearings onto the motor shaft using precise pressure.

[0003] A search revealed a patent with application number CN202322659383.0, which discloses a press for pressing motor bearings. The press includes a base frame, with storage tanks installed at both the left and right ends of the bottom of the base frame. Each storage tank has a cavity inside. A support is installed on the top of the base frame, with a cylinder installed in the middle of the top of the support, and a pressure plate installed on the end side of the support.

[0004] However, in actual use, the above patent has the following defects: when the cylinder fails, the staff cannot easily disassemble the cylinder and need to use professional disassembly tools to carry out the disassembly work, which causes great inconvenience to the staff. Therefore, we propose a motor bearing press. Utility Model Content

[0005] The purpose of this invention is to provide a motor bearing press to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a motor bearing press, including a base, with upright plates fixedly connected to the top left and right sides of the base, and mounting plates fixedly connected to the top of the upright plates. A detachable cylinder is provided between the two mounting plates, and a fixing plate is detachably installed at the telescopic end of the cylinder. Two symmetrically arranged columns are fixedly connected to the bottom of the fixing plate, and the same pressure ring is fixedly connected to the bottom of the two columns. A bearing groove is provided at the bottom of the pressure ring.

[0007] Furthermore, a placement seat is detachably installed on the top of the base corresponding to the pressure ring position. The top of the placement seat has an open structure, and a first limiting groove is opened in the middle of the side of the two mounting plates that are close to each other.

[0008] Furthermore, a first limiting block is movably engaged inside the first limiting groove. The side of the first limiting block near the cylinder passes through the first limiting groove and extends to the outside of the first limiting groove and is fixedly connected to the cylinder. The bottom and front and rear sides of the first limiting block abut against the inner wall of the first limiting groove.

[0009] Furthermore, a second limiting groove is provided on the front side of the first limiting block, and a second limiting block that can move back and forth is engaged inside the second limiting groove. The front side of the second limiting block passes through the second limiting groove and extends to the outside of the second limiting groove.

[0010] Furthermore, a groove is provided on the front side of the mounting plate near the cylinder, and a lead screw is rotatably connected to the upper rear side of the inner wall of the groove. The front end of the lead screw passes through the groove and the mounting plate in sequence and extends to the outside of the mounting plate.

[0011] Furthermore, a servo motor is fixedly connected to the front side of the mounting plate at the position corresponding to the lead screw. The output end of the servo motor is fixedly connected to the lead screw, and the output end of the servo motor and the lead screw are on the same axis. The lead screw is movably connected to the mounting plate, and a movable plate is threadedly connected to the surface of the lead screw. The movable plate passes through the groove on the side near the cylinder and extends to the outside of the groove.

[0012] Furthermore, the movable plate is movably connected to the groove, the rear side of the movable plate is fixedly connected to the front side of the second limiting block, and a fixing rod is fixedly connected to the bottom of the rear side of the inner wall of the groove. The front end of the fixing rod passes through the movable plate and extends to the outside of the movable plate, and is fixedly connected to the front side of the inner wall of the groove. The fixing rod is movably connected to the movable plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] When the cylinder needs to be disassembled, this utility model only requires starting the servo motor, which drives the lead screw to rotate counterclockwise. This causes the moving plate to move the second limiting block forward, disengaging it from the second limiting groove. Then, the cylinder is pulled upward, causing the first limiting block to move upward and disengage from the first limiting groove. Through these steps, the cylinder can be removed. The operation is simple, time-saving, and labor-saving. The entire process does not require professional disassembly tools, providing great convenience to the user. Attached Figure Description
