Description

Technical Field

[0001] This utility model relates to the field of motor assembly technology, specifically to a stop plate assembly fixture for a motor end cover. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It utilizes an energized coil (i.e., the stator winding) to generate a rotating magnetic field, which acts on the rotor (such as a squirrel-cage closed aluminum frame) to form a magnetoelectric torque.

[0003] Patent CN218162171U discloses a motor end cover stop plate assembly fixture, which includes a base and a stop plate body. A stand is installed on the upper side of the base, and a hydraulic cylinder is installed at the top inside the stand. A lower support is installed at the lower end of the hydraulic cylinder, and a sleeve base is installed on the lower side of the lower support. A pusher plate is slidably arranged on the lower outer side of the sleeve base. The device involves the stop plate body being sleeved on the lower outer side of the sleeve base. Then, the hydraulic cylinder drives the stop plate body to insert into the upper part of the mounting groove of the motor end cover. Subsequently, the first cylinder drives the pusher plate to move down and push the stop plate body into the mounting groove of the motor end cover to complete the installation. The operation is convenient and quick, the installation accuracy is high, and the efficiency of stop plate installation is greatly improved.

[0004] However, the size of the mounting base of this device is fixed, while the size of the stop plate of the motor end cover varies. Therefore, the fixed-size mounting base is difficult to meet the assembly requirements of stop plates of different sizes. If various sizes of mounting bases are made to fit the stop plates, the cost of use will increase. To address this, a stop plate assembly fixture for the motor end cover is proposed to solve the problem that the existing assembly fixtures are difficult to install conveniently according to the size of the stop plates. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a stop plate assembly fixture for a motor end cover, which solves the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stop plate assembly fixture for a motor end cover, comprising an assembly table, a fixed frame fixedly connected to the top of the assembly table, a lifting seat provided at the bottom of the fixed frame, a clamping mechanism provided at the top of the assembly table, a hydraulic cylinder fixedly connected to the top of the fixed frame, guide plates symmetrically and through the top of the fixed frame, adjusting grooves symmetrically opened at the bottom of the lifting seat, adjusting blocks slidably arranged in the inner cavity of the adjusting grooves, a limiting arc plate fixedly connected to the bottom of the adjusting blocks, a bidirectional lead screw provided in the inner cavity of the adjusting grooves, a handwheel rotatably connected to one side of the lifting seat, the bidirectional lead screw passing through the lifting seat and connected by a limiting bearing at the intersection, a discharge plate provided at the bottom of the lifting seat, movable grooves opened on both sides of the discharge plate, electric push rods provided at both ends of the lifting seat, and a controller provided on one side of the assembly table.

[0009] Preferably, the clamping mechanism includes a fixed plate symmetrically and fixedly connected to the top of the assembly table. A movable seat is provided on one side of the fixed plate. A second electric push rod is provided between the movable seat and the fixed plate. A guide rod is symmetrically and fixedly connected to one side of the movable seat. The guide rod passes through the fixed plate and the two are slidably connected.

[0010] Preferably, an arc-shaped clamp is provided on one side of the movable seat, and a movable groove is symmetrically opened on the side of the movable seat facing the arc-shaped clamp. A U-shaped seat is slidably arranged and fixedly connected to the inner cavity of the movable groove and the arc-shaped clamp, respectively. A connecting plate is provided between the movable seat and the arc-shaped clamp.

[0012] 1. The motor end cover stop plate assembly fixture places the stop plate to be assembled on the outer ring of two limiting arc plates. Then, the handwheel, in conjunction with the limiting bearing, drives the double-acting screw to rotate, causing the adjusting block in the adjusting groove, along with the limiting arc plate, to move outward. After the stop plate is limited, the hydraulic cylinder, in conjunction with the guide plate, moves the lifting seat downward, lowering the stop plate to above the motor end cover installation position. The electric push rod then drives the unloading plate to push the stop plate into the motor end cover installation groove. This solves the problem that existing assembly fixtures are difficult to conveniently limit and install according to the size of the stop plate.
