Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a disassembly tool based on an electronic steering motor controller unit. Background Art

[0002] like Figure 1 As shown, in the electronic steering system, the housing 11 of the motor controller unit 1 is connected to the heat sink 12 by glue.

[0003] When manually disassembling the motor controller unit's housing, a hand saw is required to cut the connection between the housing and the heat sink. This requires constant adjustment of the cutting direction until all connections are severed, which can be time-consuming. Furthermore, any slippage during the cutting process can cause the motor controller unit's housing to fail, potentially leading to personal injury.

[0004] Therefore, it is necessary to design a disassembly tool based on the electronic steering motor controller unit to optimize the separation method of the shell and the heat sink, reduce the operation time and personnel operation risks. Summary of the Invention

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a disassembly tool based on an electronic steering motor controller unit to optimize the separation method of the housing and the heat sink, thereby reducing operation time and human operation risks.

[0006] In order to achieve the above-mentioned purpose, the utility model is a disassembly tool based on the electronic steering motor controller unit, including a base plate, a top plate, a hydraulic cylinder, an air pump, a sliding assembly, a shell jaws, a heat sink jaws, and a mounting block. The hydraulic cylinder and the air pump are installed on the base plate, and the output end of the air pump is connected to the driving end of the hydraulic cylinder. The top plate is mounted above the hydraulic cylinder, and two mounting blocks are installed on the top plate. One end of the mounting block is connected to the top plate, and a gap is provided between the other end of the mounting block and the top plate. The size of the gap matches the flange of the motor controller unit. The middle part of the sliding assembly passes through the top plate, and the lower end of the sliding assembly is located directly above the hydraulic cylinder. The piston rod of the hydraulic cylinder contacts or separates from the lower end of the sliding assembly. After the upper end of the sliding assembly passes through the heat sink jaws, it is connected to the shell jaws. The shell jaws are fixed outside the shell of the motor controller unit, and the heat sink jaws are fixed outside the heat sink of the motor controller unit.

[0007] The shell jaws include two shell clamps, the contact surfaces of the two shell clamps are provided with clamping interfaces, and the inner surfaces of the two shell clamps are shell-shaped steps.

[0008] The shell contoured step matches the outer shape of the shell.

[0009] The heat sink jaws include two heat sink clamps, the contact surfaces of the two heat sink clamps are provided with clamping interfaces, and the inner surfaces of the two heat sink clamps are heat sink contoured steps.

[0010] The heat dissipation block contoured step matches the shape of the heat dissipation block.

[0011] The sliding assembly includes a sliding rod and a connecting plate. The upper end of the sliding rod is connected to the jaws of the shell, the middle part of the sliding rod passes through the top plate, and the lower end of the sliding rod is fixed to the connecting plate.

[0012] Compared with the existing technology, the hydraulic cylinder and the air pump provide the pulling force for disassembly, and cooperate with the sliding component and the shell jaws to realize the disassembly of the shell and the heat sink, thereby improving the efficiency of disassembly and reducing the time cost and personnel operation risk; the setting of the heat sink block jaws avoids the separation of the heat sink and the motor during the disassembly process, thereby improving the success rate of disassembly.

[0020] The present invention will now be further described with reference to the accompanying drawings.

[0021] See also Figure 2 、 Figure 6 、 Figure 7The utility model is a disassembly tool based on an electronic steering motor controller unit, including a bottom plate, a top plate, a hydraulic cylinder, an air pump, a sliding assembly, a shell jaw, a heat sink jaw, and a mounting block. A hydraulic cylinder 5 and an air pump 4 are installed on the bottom plate 2, and the output end of the air pump 4 is connected to the driving end of the hydraulic cylinder 5. The top plate 3 is mounted above the hydraulic cylinder 5. Two mounting blocks 9 are installed on the top plate 3. One end of the mounting block 9 is connected to the top plate 3, and a gap is provided between the other end of the mounting block 9 and the top plate 3. The size of the gap matches the flange 13 of the motor controller unit 1. The middle part of the sliding assembly 6 passes through the top plate 3, and the lower end of the sliding assembly 6 is located directly above the hydraulic cylinder 5. The piston rod of the hydraulic cylinder 5 contacts or separates from the lower end of the sliding assembly 6. After the upper end of the sliding assembly 6 passes through the heat sink jaw 8, it is connected to the shell jaw 7. The shell jaw 7 is fixed to the outside of the shell 11 of the motor controller unit 1, and the heat sink jaw 8 is fixed to the outside of the heat sink 12 of the motor controller unit 1.

[0022] See also Figure 3 、 Figure 4 The shell jaws 7 include two shell clamps 71 , the contact surfaces of the two shell clamps 71 have a clamping interface, and the inner surfaces of the two shell clamps 71 are shell contoured steps. The shell contoured steps match the outer shape of the shell 11 .

[0023] See also Figure 5 The heat sink jaw 8 includes two heat sink clamps 81 , the contact surfaces of the two heat sink clamps 81 have a card interface, and the inner surfaces of the two heat sink clamps 81 are heat sink contoured steps. The heat sink contoured steps match the shape of the heat sink 12 .

[0024] The sliding assembly 6 includes a sliding rod and a connecting plate. The upper end of the sliding rod is connected to the shell jaw 7, the middle part of the sliding rod passes through the top plate 3, and the lower end of the sliding rod is fixed to the connecting plate.

[0025] The mounting block 9 is used to fix the motor controller unit 1. The flange 13 of the motor controller unit 1 slides into the gap provided between the mounting block 9 and the top plate 3, so that the flange 13 is stuck between the mounting block 9 and the top plate 3. The setting of the mounting block 9 can adapt to motor controller units 1 with different flange angles.

[0026] The sliding assembly 6 is used to connect the hydraulic cylinder 5 at the bottom and the housing jaw 7 at the top. It adopts a sliding design and can adapt to motor controller units 1 of different heights.

[0027] The air pump 4 is used to provide pressure to the hydraulic cylinder 5, and the hydraulic cylinder 5 provides a large pulling force for disassembling the shell, thereby reducing the difficulty of operation and facilitating operation.

[0028] The shell jaws 7 are used to fix the shell 11 of the motor controller unit 1. The friction can be increased by increasing the surface roughness to avoid the shell jaws 7 and the contact surface of the shell 11 being separated due to the stress of separating the shell, thereby further improving the success rate of disassembly.

[0029] The heat sink jaws 8 are used to fix the heat sink 12 of the motor controller unit 1 to ensure the connection between the heat sink 12 and the motor, thereby preventing the motor and the heat sink from being separated during disassembly.

[0030] When the utility model is working, the flange 13 of the motor controller unit 1 is fixed by the mounting block 9, and the flange 13 of the motor controller unit 1 is fixed by screws. Pressure is provided to the hydraulic cylinder 5 by the air pump 4, and the piston rod of the hydraulic cylinder 5 drives the sliding assembly 6 to move upward until the height of the shell jaws 7 is consistent with the height of the shell 11 of the motor controller unit 1. The two shell clamps 71 are brought inward to complete the fixation of the shell 11. The two heat sink clamps 81 are brought inward to complete the fixation of the heat sink 12. Since the motor control unit 1 is restricted by the mounting block 9 and the heat sink jaws 8, the heat sink 12, the motor and the top plate 3 remain stationary, and pressure is continued to be provided to the hydraulic cylinder 5 by the air pump 4. The piston rod of the hydraulic cylinder 5 drives the sliding assembly 6 to continue to move upward until the shell 11 of the motor controller unit 1 and the heat sink 12 are separated, completing the disassembly process.

[0031] In this utility model, a hydraulic cylinder and air pump provide the pulling force for disassembly, working in conjunction with a sliding assembly and housing jaws to separate the housing and heat sink, improving disassembly efficiency and reducing time costs and operator risk. The heat sink jaws prevent separation of the heat sink and motor during disassembly, increasing the success rate of disassembly. This utility model is suitable for motor controller units where the housing and heat sink are secured with glue.
