Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically to a non-destructive disassembly tool for servo motors and servo housings. Background Technology

[0002] In the assembly and repair of automotive steering gears, it is often necessary to separate the assembled servo motor from the housing for testing or replacement.

[0003] Existing disassembly methods often rely on universal pullers or impact disassembly, which can easily damage the housing flange, locating pins, seals, or electrical connectors. Furthermore, if coaxiality cannot be guaranteed during disassembly, eccentric forces can damage bearings or rotors. For interference fits, glued, or stuck structures, large axial forces or heating are often required for loosening, and universal tools have poor compatibility and low efficiency.

[0004] Therefore, it is necessary to design a non-destructive disassembly tool for servo motors and servo housings, which can safely and non-destructively separate the assembled servo motors from the housings, ensuring coaxial alignment, uniform force distribution, and improving adaptability and repeatability. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a non-destructive disassembly fixture for servo motors and servo housings, which can safely and non-destructively separate the assembled servo motor from the housing, ensuring coaxial alignment, uniform force distribution, and improving adaptability and repeatability.

[0006] To achieve the above objectives, this utility model provides a non-destructive disassembly fixture for servo motors and servo housings, comprising a clamping handwheel, an upper clamping structure, a lower clamping structure, a base, a handle, a slide rail, a traction plate, a servo housing fixing device, and a servo housing clamping device. The servo housing fixing device is mounted on the base. Servo housing clamping devices and slide rails are respectively mounted on the front and rear sides of the servo housing fixing device. The end of the slide rail extends to the edge of the base. A rotatable handle is mounted on the edge of the base. The handle is rotatably connected to one end of a connecting rod, and the other end of the connecting rod is rotatably connected to the connecting piece of the traction plate. The traction plate is slidably mounted on the slide rail. The traction plate is equipped with a lower clamping structure, an upper clamping structure, and a clamping base. One end of the upper clamping structure is connected to the connecting block of the traction plate via a rotating shaft, and the other end of the upper clamping structure is connected to the lower clamping structure via a clamping handwheel. The clamping portion of the upper clamping structure has a three-point equally divided structure, and the clamping base is located below the clamping portion of the upper clamping structure.

[0007] The servo housing fixing device includes a servo housing fixing base and positioning pins. Three positioning pins are installed on the top of the servo housing fixing base, and the positions of the positioning pins match the positions of the positioning holes of the servo housing.

[0008] The servo housing clamping device includes a support base and a servo housing clamping head. The support base is fixed on the base, and the servo housing clamping head is installed on the top of the support base.

[0009] The upper clamping structure and clamping base have replaceable clamping heads.

[0010] The clamping surfaces of the upper clamping structure and the clamping base are provided with soft pads.

[0011] Compared with existing technologies, this invention employs a three-point equally divided clamping structure to achieve uniform support for the housing flange, reducing local stress; the handle-driven operation makes operation simple and allows for precise control of the traction force; the clamping structure and positioning pins ensure the coaxiality of the servo motor and the servo housing, avoiding eccentric damage; and controlled axial traction within a limited space improves the success rate of disassembling the servo motor and servo housing, reducing rework damage. By changing the clamping head of the clamping structure, different servo motors can be adapted, improving the reusability of the tooling. Attached Figure Description

[0015] The present invention will now be further described with reference to the accompanying drawings.

[0016] See Figure 1 , Figure 2This utility model is a non-destructive disassembly fixture for servo motors and servo housings, including a clamping handwheel, an upper clamping structure, a lower clamping structure, a base, a handle, a slide rail, a traction plate, a servo housing fixing device, and a servo housing clamping device. The servo housing fixing device is mounted on the base 4. Servo housing clamping devices and slide rails 6 are respectively mounted on the front and rear sides of the servo housing fixing device. The end of the slide rail 6 extends to the edge of the base 4. A rotatable handle 5 is mounted on the edge of the base 4. The handle 5 is rotatably connected to one end of a connecting rod 13. Then, the other end of the connecting rod 13 is rotatably connected to the connecting piece of the traction plate 11. The traction plate 11 is slidably mounted on the slide rail 6. The traction plate 11 is equipped with a lower clamping structure 3, an upper clamping structure 2, and a clamping base 14. One end of the upper clamping structure 2 is connected to the connecting block of the traction plate 11 by a rotating shaft. The other end of the upper clamping structure 2 is connected to the lower clamping structure 3 by a pressure handwheel 1. The clamping part of the upper clamping structure 2 has a three-point equally divided structure, which makes the force more even. The clamping base 14 is located below the clamping part of the upper clamping structure 2.

[0017] Base 4 provides rigid support for the overall tooling.

[0018] The clamping handwheel 1 provides pressure to the clamping servo motor to prevent lateral movement.

[0019] The upper clamping structure 2 and the clamping base 14 have replaceable clamping heads 12 to adapt to different models of servo motors.

[0020] The clamping surfaces of the upper clamping structure 2 and the clamping base 14 are provided with soft pads to prevent scratches or indentations on the surface of the servo motor housing.

[0021] The servo housing mounting device includes a servo housing mounting base 7 and three positioning pins 8. The positioning pins 8 are mounted on the top of the servo housing mounting base 7, and their positions match the positioning holes on the servo housing. The servo housing mounting base 7 is used to place the servo housing and provide rigid support, while the positioning pins 8 are used to fix the servo housing. The servo housing mounting base 7 can be quickly replaced to meet the disassembly requirements of different servo motor models.

[0022] The servo housing clamping device includes a support base 9 and a servo housing clamping head 10. The support base 9 is fixed on the base 4, and the servo housing clamping head 10 is mounted on the top of the support base 9. The servo housing clamping head 10 is used to clamp the servo housing.

[0023] Furthermore, to further expand functionality, the fixture can be equipped with a force detection module or displacement monitoring module, including load sensors and displacement sensors, to display or record real-time traction force and travel, and to provide overload alarms or disconnect the driving force. The fixture can also be equipped with heating or vibration devices to loosen adhesive or jammed structures, facilitating disassembly.

[0024] See Figure 3 Place the servo motor and housing assembly to be disassembled on the fixture. The servo housing is located on the servo housing fixing base 7. The positioning pin 8 positions the servo housing in the positioning hole. The servo motor is located between the lower clamping structure 3 and the upper clamping structure 2. Adjust the clamping handwheel 1 to clamp the servo motor between the lower clamping structure 3 and the upper clamping structure 2. Press down the servo housing pressure head 10 to make the servo housing more secure. Manually press the handle 5 to drive the traction plate 11 to gradually generate axial traction force along the slide rail 6, thereby driving the servo motor end to move outward. The servo housing fixing base 7, the lower clamping structure 3, and the upper clamping structure 2 remain coaxial to ensure that the traction force is transmitted along the axis and to prevent eccentric force, so as to achieve controlled gradual pulling until disassembly is completed. If adhesion or jamming occurs during the disassembly process, under the premise of clamping and fixing, a heating coil or vibrator can be used to controllably heat or vibrate the joint surface to loosen it. Then continue to press the handle 5 to complete the separation.

[0025] This invention employs a three-point equally spaced clamping structure to achieve uniform support for the housing flange, reducing localized stress. The handle-driven operation allows for simple operation and precise control of the traction force. The clamping structure and positioning pins ensure the coaxiality of the servo motor and servo housing, preventing eccentric damage. Controlled axial traction within a limited space improves the success rate of disassembling the servo motor and servo housing, reducing rework damage. By changing the clamping head of the clamping structure, different servo motors can be accommodated, improving the reusability of the tooling.
