Description

Technical Field

[0001] The utility model relates to the technical field of tooling, in particular to a special tooling for replacing intelligent motor bearings. Background Art

[0002] Motor bearings, also known as electric motor bearings or motor bearings, are special bearings specifically used in electric motors or motors. The bearings used in motors are parts that support the shaft. They can guide the rotation of the shaft and also withstand the idling parts on the shaft. In motor maintenance, bearing replacement is a common operation, but bearing removal is more troublesome, so special tooling machines are needed to assist.

[0003] Existing bearing replacement tools usually rely on manual operation, which is not only inefficient, but also easily causes bearing damage due to human factors during operation, thus affecting the operating performance of the motor. At the same time, it cannot meet the needs of disassembling motor bearings of different sizes. Therefore, we propose an intelligent motor bearing replacement tool to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art that the manual operation leads to low efficiency, easy bearing damage and inability to disassemble bearings of different sizes, and proposes a special tool for intelligent motor bearing replacement.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A special tool for replacing intelligent motor bearings comprises a support plate, a limit plate is fixedly arranged on the top of the support plate, three limit holes are opened on the limit plate at equal intervals, fixing rods are slidably connected to the inner walls of both sides of the three limit holes, fixing claws are threadedly connected to the bottoms of the three fixing rods, and a screw rod used in conjunction with the three fixing rods is threadedly passed through the top of the limit plate.

[0007] The tooling also includes:

[0008] The limiting assembly is arranged on the support plate and the limiting plate, and is used to limit the position when the three fixing rods clamp the bearing;

[0009] The driving assembly is arranged above the supporting plate and is used for driving the screw to rotate.

[0010] In a possible design, the limit assembly includes a gear plate, which is arranged on the top of the limit plate and is rotatably connected to the limit plate. Three sliding grooves corresponding to the three limiting holes are opened on the gear plate. The tops of the three fixing rods extend into the corresponding sliding grooves and are slidably connected to the sliding grooves. A handle is provided above the gear plate, and a round rod is fixed to the bottom end of the handle. A sliding groove is provided on the top of the gear plate, and the round rod extends into the sliding groove and is slidably connected to the sliding groove. A support column is fixedly provided on the top of the support plate, and the handle is rotatably connected to the top of the support column.

[0011] In a possible design, a compression spring is sleeved on the support column, the bottom of the compression spring is fixedly connected to the support plate, the top of the compression spring is fixedly connected to a fixed gear, the fixed gear passes through the support column and is slidably connected to the support column, the bottom of the handle is rotatably connected to a pressure rod, one end of the pressure rod is provided with a moving tube, and the moving tube is sleeved on the support column, one end of the pressure rod is slidably matched with the moving tube, and the fixed gear and the gear plate are meshed with each other.

[0012] In a possible design, the driving assembly includes four telescopic rods, which are evenly spaced on the top of a support plate, the bottom ends of the four telescopic rods pass through the support plate and are fixedly connected to the support plate, the tops of the four telescopic rods are fixedly connected to the same base, a motor is fixedly arranged on the top of the base, and the output end of the motor passes through the base and is fixedly connected to a screw rod.

[0013] In a possible design, a stepped groove is formed on one side of the three fixing claws that are close to each other, so as to prevent sliding when fixing the bearing.

[0014] In a possible design, the inner diameter of the moving tube is larger than the diameter of the supporting column.

[0015] The gear plate is rotated to rotate on the limit plate, and the three fixed rods on the tooling are rotated to open the three fixed rods, and then the three fixed rods on the tooling are moved to the top of the bearing to be replaced, and then the bearing is placed between the three fixed claws, and then the handle is rotated in the opposite direction to tighten the three originally opened fixed rods, so that the fixed claws on the three fixed rods clamp the bearing, and then the handle is released, and the fixed gear located under the moving tube rises due to the elastic force of the compression spring, so that the fixed gear meshes with the gear plate, and then the gear plate is fixed, so that the positions of the three fixed rods in the slide groove on the gear plate are fixed.

[0016] Then the motor starts, driving the screw to rotate, so that the screw rests on the rotor on the motor bearing. Next, continue to start the motor in the drive assembly, and the motor drives the screw to rotate. Since the screw rests on the rotor on the bearing, and four telescopic rods for support are set between the screw and the base, the telescopic rod is composed of two round rods with different diameters, and the round rod with a small diameter slides and extends into the round rod with a large diameter. Therefore, the rotation of the screw causes the telescopic rod to retract while driving the support plate to move up and down, so that the bearing clamped on the three fixed rods moves upward and disengages from the rotor of the motor, completing the disassembly of the bearing. In the process of clamping the bearing, the stepped grooves on the fixing claws on the three fixing rods can effectively prevent the bearing from sliding, thereby ensuring the stability of the bearing during the replacement process.

[0017] Beneficial effects:

[0018] In the utility model, the intelligent motor bearing replacement tooling, through the limit assembly, opens and tightens the three fixing rods, can not only clamp and fix the bearing, but also clamp bearings of different sizes, making the bearing replacement process simpler and more convenient, and enhancing the versatility and applicability of the tooling;

[0019] In the utility model, the intelligent motor bearing replacement tool is arranged on the driving assembly so that the force is evenly distributed during the bearing disassembly process, thereby reducing the damage to the bearing caused by human factors;

[0020] In the utility model, the intelligent motor bearing replacement tool is provided with a stepped groove on the fixing claw to effectively prevent the bearing from sliding or position shifting during the replacement process, thereby causing unsuccessful disassembly.

[0021] In the utility model, the three fixing rods are opened and tightened by the stepped grooves and the limit assembly on the fixing claws, which can not only clamp and fix the bearing but also clamp bearings of different sizes and prevent the bearing from sliding or position shifting during the replacement process. During the disassembly of the bearing, the driving assembly is arranged to ensure uniform force during the disassembly process, thereby reducing bearing damage caused by human factors.
