Description

Technical Field

[0001] The present invention relates to the technical field of resolver installation and testing, and in particular to a resolver fault simulation detection platform and a detection method. Background Art

[0002] In closed-loop motor control, motor speed acquisition relies on sensors. The commonly used resolvers are mostly composed of two separate parts: a stator and a rotor. Misalignment between the resolver's stator and rotor caused by assembly can distort the output waveform, ultimately leading to abnormal motor speed feedback.

[0003] Different assembly offsets can cause different distortions in the resolver's output waveform. To explore the waveform distortion patterns, researchers need a test bench that simulates the resolver's assembly offset. Prior art publications such as CN116592744A disclose an eccentricity test device for a resolver. This device simulates the planar offset of the resolver's stator using X- and Y-axis slides. However, the device lacks multi-degree-of-freedom coupling simulation capabilities and cannot fully simulate all resolver assembly offsets. Patent CN117691907A discloses a resolver assembly error detection system that uses a laser sensor to detect resolver coaxiality deviation. However, the system cannot determine the specific offset couplings that cause the effects. Knowing only the resolver offset, the system cannot derive relevant patterns.

[0004] Therefore, there is an urgent need for a detection platform that can fully simulate the resolver assembly offset and analyze the waveform distortion law. Summary of the Invention

[0005] The purpose of the present invention is to provide a resolver fault simulation detection platform and detection method, which can simulate the offset and rotation offset of the resolver in the X-axis, Y-axis, and Z-axis directions, and analyze the influence of different offsets on waveform distortion by comparing standard waveforms and distorted waveforms.

[0006] The technical solution adopted by the present invention to solve the above problems is:

[0007] The present invention includes a motor mounting module, a resolver stator mounting module, a rotation offset module, an X-axis displacement module, a Y-axis displacement module, a Z-axis displacement module, a stepper motor, a resolver stator, a resolver rotor and a reference platform. The stepper motor is connected to the reference platform through the motor mounting module.

[0008] The resolver stator and resolver rotor are used to output waveform signals. The resolver stator and resolver rotor are installed on the vertical end of the resolver stator mounting module from the outside to the inside. The horizontal end of the resolver stator mounting module is fixedly connected to the rotation offset module.

[0011] Furthermore, the Y-axis displacement module includes a Y-axis hand-tightening bolt, a Y-axis top block, a Y-axis displacement limiter and a Y-axis displacement platform.

The Y-axis displacement limiter is installed at the side end of the Y-axis displacement platform, located on the side opposite to the Y-axis hand-tightening bolt. By rotating the Y-axis hand-tightening bolt, its end contacts the Y-axis top block and pushes the Y-axis displacement platform to move along the X-axis displacement platform in the Y-axis direction.

[0012] Furthermore, the X-axis displacement module includes an X-axis hand-tightening bolt, an X-axis displacement limiter, an X-axis top block and an X-axis displacement platform. The X-axis hand-tightening bolt is connected to the side end of the X-axis displacement platform through a thread. The protruding end of the X-axis hand-tightening bolt is provided with an X-axis top block. The X-axis top block is fixed to the side wall of the X-axis displacement platform. The X-axis displacement limiter is installed at the side end of the X-axis displacement platform, located on the side opposite to the X-axis hand-tightening bolt; the upper surface of the X-axis displacement platform is slidably connected to the Y-axis displacement platform, and only allows the Y-axis displacement platform to move relative to the X-axis displacement platform in the Y-axis direction; the lower surface is slidably connected to the reference platform to realize the displacement of the X-axis displacement platform in the X-axis direction relative to the reference plane.

[0013] The detection method of a resolver fault simulation detection platform described in the present invention comprises the following steps:

[0014] Step 1: By rotating the hand-pulled bolt, Z-axis hand-tightened bolt, Y-axis hand-tightened bolt and X-axis hand-tightened bolt of the resolver fault simulation detection platform, all offsets are reset to zero, and the stepper motor is commanded to rotate a fixed angle, and the resolver outputs a standard waveform.

[0015] Step 2: Rotate the rotary table around the longitudinal axis by rotating the hand-pulled bolts to simulate the rotational offset during the resolver assembly process.

[0016] Step 3: Rotate the Y-axis hand-tightening bolt to achieve the displacement of the Y-axis displacement platform relative to the reference plane in the Y-axis direction, simulating the offset in the Y-axis direction during the resolver assembly process;

[0018] Step 5: Rotate the Z-axis hand-tightening bolt to achieve the displacement of the Y-axis displacement platform relative to the reference plane in the Z-axis direction, simulating the offset in the Z-axis direction during the resolver assembly process;

[0019] In step six, the stepper motor is commanded to rotate the angle in step one. The resolver outputs a distorted waveform. This waveform is caused by assembly offset. This waveform is compared with the standard waveform to obtain the distortion pattern of the output waveform under different assembly offsets.

[0027] Specific implementation method 1: Combination Figures 1 to 3 This embodiment describes a resolver fault simulation detection platform, which includes a motor mounting module 1, a resolver stator mounting module 2, a rotation offset module, an X-axis displacement module, a Y-axis displacement module, a Z-axis displacement module, a stepper motor 7-1, a resolver stator 7-2, a resolver rotor 7-3 and a reference platform 8. The stepper motor 7-1 is connected to the reference platform 8 through the motor mounting module 1. The stepper motor mounting module is an L-shaped connector, the vertical end of which is fixedly connected to the casing of the stepper motor by bolts, and the horizontal end is fixedly connected to the reference plane by bolts.

[0028] The resolver stator and resolver rotor are used to output waveform signals. The resolver stator 7-2 and resolver rotor 7-3 are installed from the outside to the inside on the vertical end of the resolver stator mounting module 2. The horizontal end of the resolver stator mounting module 2 is fixedly connected to the rotation offset module. The rotation offset simulation of the resolver stator is achieved by rotating the rotation offset module's rotating table. The output shaft of the stepper motor 7-1 passes through the vertical end of the resolver stator mounting module 2 and is fixedly connected to the resolver rotor 7-3. The output shaft of the stepper motor 7-1 is parallel to the X-axis.

[0029] The rotation offset module, the Z-axis displacement module, the Y-axis displacement module and the X-axis displacement module are sequentially installed from top to bottom. The Z-axis displacement module is connected to the rotation offset module via a rotating shaft. The Y-axis displacement module is fixedly connected to the Z-axis displacement module and is slidably connected to the X-axis displacement module. The Y-axis displacement module is displaced in the Y-axis direction relative to the reference platform (8). The X-axis displacement module is slidably connected to the reference platform 8, so that the X-axis displacement module is displaced in the X-axis direction relative to the reference platform 8.

[0030] Specific implementation method 2: Combination Figures 1 to 3To illustrate this embodiment, the rotational offset module described in this embodiment includes a hand-pull bolt 3-1, a rotational offset limiter 3-2, a tightening bolt 3-3 and a rotating table 3-4. The tightening bolt 3-3 and the hand-pull bolt 3-1 are arranged opposite to each other, both are installed at the side end of the rotating table 3-4 and are threadedly engaged with the rotating table 3-4; the rotational offset limiter 3-2 is inserted into the limiting groove at the side end of the rotating table 3-4, the rotational offset limiter 3-2 is located between the tightening bolt 3-3 and the hand-pull bolt 3-1, and the inner end portion contacts the rotating table, which is used to limit the rotation angle of the rotational offset module to prevent the rotational displacement from being caused by excessive rotational offset of the rotating table.

[0031] Rotate the rotation offset limiter 3-2 clockwise, and its end can press against the rotating platform 3-4, so that it becomes one with the rotating platform 3-4 after pressing; rotate the rotation offset limiter 3-2 counterclockwise to separate it from the rotating platform 3-4, so as to prevent accidental contact with the hand-tightening bolt.

[0032] Rotate the tightening bolt 3-3 clockwise to displace it inward and tighten the rotation offset limiter 3-2; rotate the tightening bolt 3-3 counterclockwise to displace it outward and separate it from the rotation offset limiter 3-2.

[0033] Rotate the hand-pull bolt 3-1 clockwise to move it inward and tighten it against the rotation offset limiter 3-2; rotate the hand-pull bolt 3-1 counterclockwise to move it outward and separate it from the rotation offset limiter 3-2.

[0034] The rotation of the rotating platform 3-4 in two directions is controlled respectively by the rotation of the tightening bolt 3-3 and the hand-pulling bolt 3-1.

The Z-axis hand-tightening bolt 5-1 and the Z-axis displacement platform 5-3 are matched through threads, and the Z-axis displacement platform 5-3 is driven to displace along the Z-axis (vertical direction) by rotating the Z-axis hand-tightening bolt 5-1; the Z-axis displacement limiter 5-2 is installed in the limit slot of the Z-axis displacement platform 5-3, and the Z-axis displacement limiter 5-2 slides in the limit slot of the Z-axis displacement platform. The displacement range of the Z-axis displacement platform 5-3 is limited by adjusting the position of the limit block to prevent the rotational sweeping caused by excessive displacement of the rotating table in the Z-axis direction.

[0037] When the Z-axis hand-tightening bolt 5-1 is rotated, the threaded pair converts the rotational motion into the Z-direction linear displacement of the platform. The Z-axis hand-tightening bolt 5-1 is horizontally installed on the side end of the Z-axis displacement platform 5-3, and an inclined wedge slider is provided at its end. The upper surface of the inclined wedge slider is an inclined surface, and an inclined groove matching the inclined surface is machined inside the Z-axis displacement platform 5-3. When the Z-axis hand-tightening bolt 5-1 is rotated, the inclined wedge slider is pushed to move horizontally, and the Z-axis displacement platform 5-3 is pushed up and down vertically through the inclined surface.

[0038] Rotate the Z-axis hand-tightening bolt 5-1 to move the Z-axis displacement platform 5-3 to the initial position.

[0039] When the Z-axis hand-tightening bolt 5-1 is rotated clockwise, the Z-axis displacement platform 5-3 rises along the Z-axis direction, and the resolver stator is raised relative to the rotor; when the Z-axis hand-tightening bolt 5-1 is rotated counterclockwise, the Z-axis displacement platform 5-3 falls along the Z-axis direction, and the resolver stator is lowered relative to the rotor.

[0040] The Z-axis displacement platform 5-3 is connected to the rotation offset module through a rotating shaft, so that the rotation table 3-4 rotates around the Z-axis and can move up and down as a whole with the Z-axis displacement platform 5-3.

The protruding end of the Y-axis hand-tightening bolt 4-1 is provided with a Y-axis top block 4-2. The Y-axis top block 4-2 is fixed to the side wall of the Y-axis displacement platform 4-3. The Y-axis displacement limiter is installed in the limit groove at the side end of the Y-axis displacement platform 4-3, located on the side opposite to the Y-axis hand-tightening bolt 4-1, and is used to limit the displacement of the Y-axis displacement platform 4-3 relative to the reference plane 8, so as to prevent the rotational sweeping of the bore caused by excessive displacement of the rotary table in the Y-axis direction.

[0045] By rotating the Y-axis hand-tightening bolt 4-1, its end contacts the Y-axis top block 4-2 and pushes the Y-axis displacement platform 4-3 to move along the X-axis displacement platform 6-4 in the Y-axis direction. When the Y-axis displacement platform 4-3 moves, the Z-axis displacement module and the rotation offset module move synchronously.

[0046] The other components and connection methods of this embodiment are the same as those of the first, second or third embodiment.
