Description

Technical Field

[0001] This utility model relates to the field of motor disassembly technology, and more specifically, to a motor disassembly tooling device. Background Technology

[0002] In the field of industrial production and equipment maintenance, motors, as core power components, inevitably experience malfunctions or performance degradation after long-term operation, requiring disassembly and repair, component replacement, or resource recycling.

[0003] Currently, the process of disassembling a motor involves placing the motor on a disassembly table. Since there are multiple screws installed on the motor casing, the first step in disassembling the motor is to remove these screws. However, the current disassembly method involves manual disassembly of the motor without any positioning equipment. This causes the motor to easily shift during disassembly, making it inconvenient to remove the screws and reducing the efficiency of motor disassembly. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a motor disassembly tooling device that overcomes or at least partially solves the above technical problems.

[0005] This utility model is implemented as follows: This utility model provides a motor disassembly fixture, including a base and a support plate. The support plate is fixedly installed on the upper surface of the base, and a locking component is installed on the upper surface of the support plate for limiting the disassembly of the motor.

[0006] In a preferred embodiment, the locking element includes a round rod, a connecting plate, and a connecting plate, wherein the round rod is fixedly mounted on the upper surface of the support plate, and the connecting plate is rotatably mounted on the round rod.

[0007] In a preferred embodiment, a connecting plate is fixedly mounted on one end of the connecting plate, and the connecting plate is configured in an L-shape.

[0008] In a preferred embodiment, the lateral end surface of the connecting plate is provided with a circular hole.

[0009] In a preferred embodiment, the upper surface of the support plate is provided with a plurality of through holes, which are evenly arranged on the upper surface of the support plate, and the diameter of the through holes is set to be the same as the diameter of the circular holes. A positioning pin is inserted into the interior of the circular holes and extends into the interior of the corresponding through holes.

[0010] In a preferred embodiment, the locking elements are configured in four groups, with two groups of locking elements connected by a reinforcing member.

[0011] In a preferred embodiment, the reinforcing member includes a connecting cross plate, the outer surface of which has a threaded hole, and a screw is provided inside the threaded hole.

[0012] In a preferred embodiment, the support plate is rectangular in shape, and a collection box is fixedly installed at one end of the support plate.

[0013] The present invention provides a motor disassembly fixture, the advantages of which include: 1. By installing a round rod on the support plate, and rotating a connecting plate on the round rod, a connecting plate is also fixedly installed at one end of the connecting rod. When limiting the motor, a positioning pin can be used to pass through the inside of the connecting plate and through the inside of the motor base into the inside of the support plate. This can limit the motor and prevent it from shifting when disassembling it, thus improving disassembly efficiency.

[0014] 2. A connecting horizontal plate is installed at the end of the connecting plate. The horizontal plate is bolted to the end of the connecting plate and can be disassembled. A screw is threaded inside the connecting horizontal plate and presses against the outer surface of the motor base, thereby improving the stability of the motor on the support plate and facilitating the disassembly of the motor.

[0018] 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 some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Example Reference Figures 1-4 This utility model provides a technical solution: a motor disassembly fixture, including a base 1 and a support plate 2. The support plate 2 is fixedly installed on the upper surface of the base 1. A locking element 3 is installed on the upper surface of the support plate 2 for limiting the disassembly of the motor. The base 1 is integrally welded from a high-strength Q235 steel plate. An adjustable anti-slip pad is installed at the bottom. The pad is made of nitrile rubber, which can not only adapt to different ground flatness, but also effectively buffer vibration and prevent the fixture from shifting during disassembly. The base 1 includes a disc base and a vertical support rod, which are designed as a single unit. The height of the base 1 is 1500mm. The support plate 2 is made of Q345B low alloy high-strength steel plate with a yield strength ≥345MPa. The surface is phosphated and then sprayed with anti-rust paint with a coating thickness of 50μm. The support plate 2 is rectangular in shape with dimensions of 600mm long × 300mm wide × 100mm thick. The edges of the rectangle are rounded with a radius of R3mm to prevent sharp edges from scratching the operator.

[0020] In a preferred embodiment, the locking member 3 includes a round rod 31, a connecting plate 32, and a connecting plate 33. The round rod 31 is fixedly installed on the upper surface of the support plate 2, and the connecting plate 32 is rotatably installed on the round rod 31. The connecting plate 33 is fixedly installed at one end of the connecting plate 32. The connecting plate 33 is L-shaped. The round rod 31 is made of solid round steel with a diameter of 20mm and a length of 180mm. The connecting plate 32 is made of rectangular steel plate cut to size, with a length of 220mm × width of 30mm × thickness of 8mm. A 21mm diameter round hole 4 is opened in the middle of the connecting plate 32 to fit the round rod 31 with a clearance of 1mm. Both ends of the connecting plate 32 are rounded. The connecting plate 33 is an integrally formed L-shaped structure consisting of a vertical section + water... The system consists of two sections, each made of steel plate. The vertical section is 100mm long, 30mm wide, and 8mm thick, with a 10mm rounded top. The horizontal section is 80mm long, 30mm wide, and 8mm thick, with its end bent downwards by 5mm away from the vertical section to form a non-slip edge. The inner angle of the L-shaped connecting plate 33 is 90°±0.5°, with a rounded corner radius R5mm at the inner angle to avoid stress concentration. The top of the vertical section of the L-shaped connecting plate 33 is welded to the free end of the connecting plate 32, with a welding length of 30mm and a weld height of 6mm. CO2 gas shielded welding is used, and stress relief treatment is performed after welding. After welding, the horizontal section of the L-shaped connecting plate 33 remains perpendicular to the connecting plate 32.

[0021] The upper surface of the support plate 2 has several through holes 5, which are evenly distributed on the upper surface of the support plate 2. The diameter of the through holes 5 is the same as that of the circular holes 4. The positioning pins 6 are inserted into the circular holes 4 and extend into the corresponding through holes 5. The diameter of the through holes 5 and the circular holes 4 of the connecting plate 32 are consistent, both being 21mm, to ensure that the positioning pins 6 can be smoothly inserted. The clearance tolerance is controlled at H7 / g6, which avoids loosening and facilitates insertion and removal. The length of the positioning pin 6 is 30mm, of which the insertion section is 20mm long, penetrating the connecting plate 32, with a thickness of 8mm and extending into the through hole 5 by 12mm. The depth of the through hole 5 is 8mm, and the actual insertion is 8mm, with a 4mm safety margin reserved. The handheld section is 10mm long.

[0022] The locking components 3 are configured in four sets, with two sets of locking components 3 connected by reinforcing components 7. The reinforcing component 7 includes a connecting horizontal plate 71. The outer surface of the connecting horizontal plate 71 has a threaded hole, and a screw 8 is provided inside the threaded hole. The screw 8 is made of a rectangular long steel plate, 80mm long × 20mm wide × 10mm thick, and is made of Q345B low alloy high strength steel plate with a tensile strength ≥470MPa and a yield strength ≥345MPa. It can withstand the maximum axial pressure of 800N applied by the screw 8 without deformation. The screw 8 engages with the threaded hole of the connecting horizontal plate 71 through the thread. When the screw 8 is rotated clockwise, the screw 8 moves downward and the bottom top block presses against the motor base. When the screw 8 is rotated counterclockwise, the reaction force disappears, and the pressure on the motor base can be released.

[0023] The support plate 2 is rectangular in shape, and the collection box 9 is fixedly installed at one end of the support plate 2. The collection box 9 is a rectangular open box with a length of 300mm × width of 280mm × height of 150mm. The side walls and bottom of the box are made of 1.5mm thick cold-rolled steel plate, and the four corners of the bottom are rounded with R5mm to prevent waste from accumulating in dead corners. It is recommended to clean the collection box 9 after disassembling 3-5 motors.

[0024] Specifically, the working process or working principle of a motor disassembly tooling device is as follows: When disassembling a motor, this equipment can limit the motor, so that the motor can be stably disassembled on the support plate 2, avoiding the shaking of the disassembly screws, thereby improving the efficiency of motor disassembly.

[0025] Place the motor on the upper surface of the support plate 2, then move the connecting plate 33 to the position of the mounting hole on the motor base, and align the round hole 4 on the support plate 2 with the position of the mounting hole. Then insert the positioning pin 6 into the round hole 4, pass through the round hole 4 and the mounting hole, and extend into the through hole 5. The positioning pin 6 is engaged in the through hole 5. By limiting the motor base, the motor is limited, and the motor can be disassembled stably, including the screws on the motor housing.

[0026] Because sometimes a hammer is used to strike the motor housing during disassembly, which can loosen the housing and cause the motor to vibrate, thus compromising its original stability, this device installs a connecting plate 71 on the side of the connecting plate 33. The connecting plate 71 and the connecting plate 33 can be stably connected together using wing bolts.

[0027] At this point, the connecting plate 71 aligns with the surface of the motor base. Then, screw the screw 8 into the connecting plate 71 and press one end of the screw 8 against the motor base to improve the stability of motor disassembly.
