Description

Technical Field

[0001] This utility model relates to the field of vibration testing fixtures for horizontal motors, specifically a vibration testing fixture for horizontal motors. Background Technology

[0002] Motorized equipment (such as air conditioners, refrigerators, washing machines, and vehicles) generates vibrations during operation, resulting in noise. Excessive noise can negatively impact the user experience, and vibrations exceeding preset limits can damage the equipment, reducing its lifespan. For example, if an air conditioner vibrates beyond preset limits, the noise will affect the user experience, and the vibration can cause malfunctions such as pipe breakage. Therefore, vibration testing is necessary when motorized equipment leaves the factory.

[0003] In the prior art, such as in publication number CN206832356U, a vibration measuring device for motor equipment is disclosed. It includes a mounting base, with an anti-slip pad bonded to the bottom of the mounting base by an adhesive. Connecting plates are welded to both ends of the mounting base, and internal threaded holes are longitudinally opened on the connecting plates. Stop plates are provided at the four edges of the top of the mounting base. A recording plate is horizontally arranged at the center of the top of the mounting base. Clamps are held at both ends of the recording plate. The bottom of the clamps is connected to the top of the mounting base by screws. Support legs are provided at the four corners of the top of the mounting base. The four sets of support legs are located between the four sets of stop plates. The top of the support legs is connected to an upper top plate by screws.

[0004] While the aforementioned patent records motor performance and product qualification rate by moving a recording pen on a recording board, it is simple, easy to implement, and has low operating costs. However, it lacks a structure for intelligent monitoring and adjustment of the pressure on the contact surface between the vibration meter and the motor. This can easily lead to damage to the vibration meter probe due to excessive pressure at the contact point, or insufficient pressure causing the probe to not fully contact the motor, thus affecting the testing structure. Furthermore, the lack of a structure for quickly fixing the motor affects the efficiency of continuous testing. Therefore, to address the above problems, a horizontal motor vibration testing fixture is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, such as the lack of a structure for intelligent monitoring and adjustment of the pressure at the contact surface between the vibration meter and the motor, which can easily lead to damage to the vibration meter probe due to excessive pressure at the contact point or incomplete contact between the probe and the motor due to insufficient pressure, thus affecting the detection structure; in addition, the lack of a structure for rapid fixation of the motor affects the efficiency of continuous detection. Therefore, this utility model proposes a vibration detection fixture for horizontal motors.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The vibration detection fixture for a horizontal motor of this utility model includes a detection table, a support fixedly connected to the top surface of the detection table, a detection component provided at one end of the support, an equipment port opened on the surface of the detection table, a positioning component fixedly connected to the surface of the equipment port, and a horizontal motor provided on the top surface of the positioning component.

[0007] The detection assembly includes an electric push rod fixedly connected to the bottom surface of one end of the bracket. A pressure sensor is fixedly connected to the bottom end of the electric push rod. A frame is fixedly connected to the bottom surface of the pressure sensor. A vibration meter is fixedly connected inside the frame. A cavity is opened at one end of the bracket. A control board is sleeved inside the cavity.

[0008] The positioning component includes a track fixedly connected to the surface of the device opening. A drive motor is fixedly connected to the back of the track. A swing plate is fixedly connected to one end of the output end of the drive motor that passes through the side of the track. A pull rod is rotatably connected to both sides of the swing plate. A connecting plate is rotatably connected to one end of the pull rod. A clamping block is fixedly connected to the top of the connecting plate. The clamping block is slidably connected to the top surface of the track.

[0009] Preferably, the bottom end of the electric push rod is connected to the frame via a pressure sensor, the vibration meter is fixed inside the frame and electrically connected to the control board, and the control board controls the extension and retraction of the electric push rod according to the real-time pressure signal from the pressure sensor to adjust the contact pressure between the vibration meter and the surface of the horizontal motor.

[0010] Preferably, the output end of the drive motor drives the swing plate to rotate, and the swing plate drives the two connecting plates to move synchronously through the pull rods on both sides. The clamping blocks move closer or further away from each other along the top surface of the track, and the drive motor has a built-in brake structure to lock the clamping state of the clamping blocks on the horizontal motor.

[0011] Preferably, the clamping block has a clamping surface on the side facing the horizontal motor that matches the curvature of the motor housing, and the surface of the clamping surface is covered with a rubber anti-slip layer.

[0012] Preferably, the top surface of the track is provided with a guide T-slot, and the bottom of the clamping block is fixedly connected to a slider that slides in cooperation with the guide T-slot.

[0013] Preferably, the control board is electrically connected to the drive motor. After the clamping block clamps the horizontal motor, it controls the electric push rod to move down so that the vibration meter contacts the motor surface. The pressure sensor feeds back a signal to the control board to adjust the electric push rod to keep the contact pressure of the vibration meter constant.

[0014] The advantages of this utility model are:

[0015] 1. This utility model uses the pressure sensor to monitor the pressure signal of the contact surface between the vibration meter and the horizontal motor in real time, and feeds it back to the control board. The control board controls the electric push rod to make fine adjustments to the displacement, so that the contact pressure between the vibration meter and the motor surface remains constant. This avoids the problem of damage to the vibration meter probe due to excessive pressure, and also prevents poor contact of the vibration meter due to insufficient pressure, thereby ensuring the accuracy of vibration detection data.

[0016] 2. This utility model drives the swing plate to rotate via a drive motor, which in turn drives the connecting plates and clamping blocks on both sides to move rapidly towards each other along the top surface of the track, thereby achieving automatic clamping and fixing of the horizontal motor. Combined with the built-in brake structure of the drive motor to lock the clamping state, it significantly shortens the motor clamping time and improves the efficiency of continuous inspection operations.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1-4 As shown, a vibration testing fixture for a horizontal motor includes a testing table 1, a support 2 fixedly connected to the top surface of the testing table 1, a testing component 3 provided at one end of the support 2, an equipment opening on the surface of the testing table 1, a positioning component 4 fixedly connected to the surface of the equipment opening, and a horizontal motor 5 provided on the top surface of the positioning component 4.

[0025] The detection component 3 includes an electric push rod 31 fixedly connected to the bottom surface of one end of the bracket 2. A pressure sensor 32 is fixedly connected to the bottom end of the electric push rod 31. A frame 33 is fixedly connected to the bottom surface of the pressure sensor 32. A vibration meter 34 is fixedly connected inside the frame 33. A cavity is opened at one end of the bracket 2. A control board 35 is sleeved inside the cavity.

[0026] During operation, the horizontal motor 5 to be tested is placed on the top surface of the track 41 of the positioning component 4. The drive motor 42 is started to drive the swing plate 43 at the output end to rotate, so that the pull rods 44 connected to both sides of the swing plate 43 synchronously pull the connecting plate 45 and the clamping block 46 to slide along the top surface of the track 41 and move closer to each other. The horizontal motor 5 is clamped and fixed by the arc-shaped clamping surface and the rubber anti-slip layer on the inner side of the clamping block 46. The brake structure built into the drive motor 42 locks the position of the clamping block 46.

[0027] Furthermore, the positioning component 4 includes a track 41 fixedly connected to the surface of the equipment port. A drive motor 42 is fixedly connected to the back of the track 41. A swing plate 43 is fixedly connected to one end of the output end of the drive motor 42 that passes through the side of the track 41. A pull rod 44 is rotatably connected to both sides of the swing plate 43. A connecting plate 45 is rotatably connected to one end of the pull rod 44. A clamping block 46 is fixedly connected to the top of the connecting plate 45. The clamping block 46 is slidably connected to the top surface of the track 41.

[0028] During operation, the control board 35 then activates the electric push rod 31 to extend downwards, driving the pressure sensor 32 (Honeywell FSG15N1A), frame 33, and vibration meter 34 (Fluke 805 vibration detector) to move downwards until the vibration meter 34 contacts the surface of the horizontal motor 5. The pressure sensor 32 monitors the contact pressure in real time and feeds back the signal to the control board 35 (Siemens S7-1200 PLC). The control board 35 dynamically adjusts the extension and retraction of the electric push rod 31 according to the preset pressure threshold, so that the pressure between the vibration meter 34 and the motor contact surface remains constant.

[0029] Furthermore, the top surface of the track 41 is provided with a guide T-slot, and the bottom of the clamping block 46 is fixedly connected to a slider that slides in cooperation with the guide T-slot;

[0030] During operation, the guide T-slot on the top surface of the track 41 slides in conjunction with the slider at the bottom of the clamping block 46. When the drive motor 42 drives the swing plate 43 to rotate, the pull rod 44 pulls the connecting plate 45, causing the clamping block 46 to move along the track 41. The slider slides into the guide T-slot, and the limiting flanges on both sides of the T-slot prevent the slider from coming out, ensuring the linear stability of the movement trajectory of the clamping block 46. This structure, through the mechanical constraint of the guide T-slot and the slider, prevents the clamping block 46 from shifting or jamming when clamping or releasing the horizontal motor 5, improving the smoothness of the clamping action and the positioning accuracy. At the same time, the arc-shaped clamping surface combined with the rubber anti-slip layer ensures that the clamping force is evenly distributed, preventing damage to the motor housing due to excessive local pressure.

[0031] Furthermore, the control board 35 is electrically connected to the drive motor 42. After the clamping block 46 clamps the horizontal motor 5, it controls the electric push rod 31 to move down so that the vibration meter 34 contacts the motor surface. The pressure sensor 32 feeds back a signal to the control board 35 to adjust the electric push rod 31 to keep the contact pressure of the vibration meter 34 constant.

[0032] During operation, after the drive motor 42 completes clamping of the horizontal motor 5, the control board 35 receives the clamping position signal and triggers the electric push rod 31 to move downward, causing the vibration meter 34 to contact the motor surface. The pressure sensor 32 detects the contact pressure in real time and feeds the signal back to the control board 35. The control board 35 dynamically adjusts the extension and retraction of the electric push rod 31 according to the preset pressure threshold to maintain a constant pressure between the vibration meter 34 and the motor contact surface. This implementation achieves automated connection of the clamping and detection process through the linkage control of the control board 35, drive motor 42, pressure sensor 32, and electric push rod 31, reducing manual intervention. At the same time, the constant pressure ensures that the probe of the vibration meter 34 is always in close contact with the motor surface, avoiding detection errors caused by pressure fluctuations, and significantly improving the accuracy and repeatability of vibration detection data.

[0033] Working principle: During operation, the horizontal motor 5 is placed on the top surface of the track 41 of the positioning component 4. The drive motor 42 is started, which drives the swing plate 43 at its output end to rotate. The pull rods 44 connected to both sides of the swing plate 43 simultaneously pull the two connecting plates 45, causing the clamping blocks 46 at the top of the connecting plates 45 to slide towards each other along the guide T-slots on the top surface of the track 41. The arc-shaped clamping surface and rubber anti-slip layer on the inner side of the clamping block 46 stably clamp the motor. The brake structure built into the drive motor 42 locks the clamping state. Then, the control board 35 starts the detection component 3. The push rod 31 moves downward, causing the pressure sensor 32, frame 33, and vibration meter 34 to contact the surface of the horizontal motor 5. The pressure sensor 32 detects the contact pressure in real time and feeds back the signal to the control board 35. The control board 35 dynamically adjusts the extension and retraction of the electric push rod 31 according to the preset pressure threshold, so that the pressure of the vibration meter 34 and the contact surface of the motor remains constant for vibration detection. After the detection is completed, the control board 35 controls the electric push rod 31 to retract and drives the motor 42 to reverse and drive the clamping block 46 to reset, realizing the rapid disassembly of the horizontal motor 5 and the continuous detection of the next workpiece.
