Description

Technical Field

[0001] This utility model relates to the field of motor maintenance, and more specifically, to a fixture for installing and fixing a motor rear end cover wire clamp. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It utilizes a rotating magnetic field generated by a current-carrying coil, also known as a stator winding, to act on the rotor, creating magnetoelectric torque. Electric motors are classified into DC motors and AC motors according to the power source they use. Most motors in power systems are AC motors, which can be synchronous or asynchronous motors. An electric motor mainly consists of a stator and a rotor. The direction of the force on a current-carrying conductor in a magnetic field is related to the direction of the current and the direction of the magnetic field lines. The working principle of an electric motor is that the magnetic field exerts a force on the current, causing the motor to rotate.

[0003] To prevent damage to the motor's rotary transformer wiring harness during the assembly of the motor's stator and rotor, wire clamps are required to secure the harness at the rear end cover of the motor. Currently, most tooling uses KBK lifting devices placed on a fixed rod for hollow shafts, with personnel installing them from below the rear end cover of the motor. Because the wire clamps are designed for tight fit, an upward force is required during installation, which can easily cause the rotor to tilt and slip, posing a risk of injury to workers. Additionally, if the product falls to the ground, it can easily be damaged, affecting product quality. Utility Model Content

[0004] To overcome the potential hazard of rear end cover slippage causing injury to installers while working under the equipment, this utility model provides a motor rear end cover clamp mounting fixture, including a base. An adjusting rod is movably mounted on the inner wall of the base. A rotating back plate is fixedly mounted on the outer side of the adjusting rod. An installation frame is fixedly mounted on the outer wall of the rotating back plate. A clamping assembly is threaded into the inner side of the installation frame. A receiving collar is fixedly mounted on the outer wall of the rotating back plate. A positioning assembly is fixedly mounted on the outer wall of the base. A bearing seat is fixedly mounted on the inner wall of the base. One end of the adjusting rod is movably mounted inside the bearing seat, and the other end passes through the side wall of the base and extends to the outside of the base.

[0005] Preferably, the base is U-shaped.

[0006] Preferably, the adjusting rod includes a driven rod, one end of which is movably installed inside the bearing housing, and the other end is fixedly installed with a crank. A positioning screw hole is provided inside the driven rod.

[0007] The driven rod is used to rotate the back plate, thereby changing the installation direction of the motor.

[0008] Preferably, the positioning component includes a positioning plate, which is fixedly installed on the outer wall of the base and located above the driven rod. A positioning screw is installed on the internal thread of the positioning plate, and the positioning screw is adapted to the positioning screw hole.

[0009] The locating screw is used to connect with the locating screw hole to position the driven rod.

[0010] Preferably, the mounting frame is C-shaped, and threaded grooves are provided on both the left and right side walls of the mounting frame.

[0011] Preferably, there are two clamping components, and each clamping component includes a threaded push rod. The two threaded push rods are respectively threaded into the interior of two threaded grooves. A connecting bearing is provided at the opposite end of each of the two threaded push rods. A clamping plate is fixedly installed on the outer wall of each of the two connecting bearings. A fixing screw hole is provided on the top of each of the two clamping plates.

[0012] Preferably, the receiving collar is L-shaped.

[0013] It can effectively fix one end of the motor output shaft.

[0014] Preferably, the receiving collar is located on the same side of the two clamping plates.

[0015] Beneficial effects:

[0016] The beneficial effects of adopting the technical solution of this utility model are as follows:

[0017] (1) By installing a receiving collar and a clamping assembly on the rotating back plate, the receiving collar is inserted and positioned at one end of the motor. Then, the two clamping assemblies are rotated to move in opposite directions to clamp the motor. After fixing the motor, the adjusting rod is rotated to make the rear end of the motor rotate upward, which makes it convenient for the staff to install the wire clamp and the subsequent rear end cover installation work.

[0018] (2) By installing a positioning component on the outer wall of the base, the positioning component is located above the positioning screw hole when the driven rod drives the rotating back plate to turn upward or downward. After adjusting the direction of the rotating back plate and the motor, the positioning component can be rotated to connect with the positioning screw hole on the driven rod to position it, thus avoiding the problem of shaking during installation. The method of fixing the motor by rotating the back plate is safer than the installation of the lifting device. It is convenient to operate and has higher safety, which can avoid the situation of equipment falling and personnel injury. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments. The specific embodiments are as follows:

[0027] like Figure 1 and 3As shown, a motor rear end cover clamp mounting fixture includes a base 1. An adjusting rod 2 is movably mounted on the inner wall of the base 1. A rotating back plate 3 is fixedly mounted on the outside of the adjusting rod 2. A mounting frame 4 is fixedly mounted on the outer wall of the rotating back plate 3. A clamping assembly 5 is threadedly mounted inside the mounting frame 4. A receiving collar 6 is fixedly mounted on the outer wall of the rotating back plate 3. A positioning assembly 7 is fixedly mounted on the outer wall of the base 1. A bearing seat 11 is fixedly mounted on the inner wall of the base 1. One end of the adjusting rod 2 is movably mounted inside the bearing seat 11, and the other end passes through the side wall of the base 1 and extends to the outside of the base 1. The base 1 is U-shaped, and the mounting frame 4 is C-shaped. Threaded grooves are provided on both the left and right side walls of the mounting frame 4. There are two clamping assemblies 5, and each clamping assembly 5 includes a threaded push rod 51. The two threaded push rods 51 are threadedly mounted inside the two threaded grooves. A connecting bearing 52 is provided at the opposite end of each of the two threaded push rods 51. A clamping assembly 52 is fixedly mounted on the outer wall of each of the two connecting bearings 52. The top of each of the two clamping plates 53 is provided with a fixing screw hole 54. The receiving collar 6 is L-shaped and located on the same side of the two clamping plates 53. The receiving collar 6 is used to insert and fix one end of the motor, while the other end of the motor needs to be fixed by the clamping plates 53 on both sides. By rotating the threaded push rod 51, the two clamping plates 53 are moved in opposite directions and fit against the outside of the motor by moving the threaded groove inside the mounting frame 4. At the same time, the operator installs wire clamps through the fixing screw holes 54 to fix the motor rotary transformer wire harness, so as to avoid the problem of damaging the wire harness when the motor stator and rotor are closed.

[0028] In addition, since the rear end of the motor will face upward after rotation, it is convenient for installers to carry out installation work from above, improving work efficiency, and preventing the safety hazard of the rear end cover of the motor slipping off and causing injury to people.

[0029] like Figure 2 As shown, the adjusting rod 2 includes a driven rod 20. One end of the driven rod 20 is movably installed inside the bearing seat 11, and the other end is fixedly installed with a crank 22. The driven rod 20 has a positioning screw hole 21 inside. When installing the motor, the receiving collar 6 is located above the two clamping components 5. To prevent it from falling off, the two sides of the motor need to be fixed first by the clamping components 5. After fixing the motor, the driven rod 20 cooperates with the bearing seat 11 to rotate the rotating back plate 3 upward so that the rear end of the motor faces upward.

[0030] It should be noted that the positioning component 7 includes a positioning plate 71, which is fixedly installed on the outer wall of the base 1 and is located above the driven rod 20. The positioning plate 71 has a positioning screw 72 installed inside its internal thread. The positioning screw 72 is adapted to the positioning screw hole 21. When handling the motor rear end cover and installing the wire clamp, it is necessary to fix the driven rod 20 to prevent it from shaking. After adjusting the angle of the rotating back plate 3, rotate the positioning screw 72 to connect with the positioning screw hole 21 opened in the driven rod 20 to form a fixation, preventing the motor equipment from falling off and being smashed due to the shaking of the driven rod 20 during the installation operation.

[0031] Working principle: Connect one end of the motor to the receiving collar 6, and rotate the two threaded push rods 51 to clamp the motor with the two clamping plates 53. After the motor is fixed, rotate the crank 22 to drive the driven rod 20 to rotate. As the driven rod 20 rotates, it will drive the rotating back plate 3 and the motor to rotate together. When the motor is rotated to the angle with the rear end facing upward, the positioning screw 72 is threaded to the positioning screw hole 21 on the driven rod 20 to form a positioning. This makes it convenient for installers to install the wire clamp from above, which is convenient to operate and will not damage the wire harness.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
