Description
Technical Field
[0001] The present invention relates to the technical field of drive strength detection, and particularly to a strength detection device for drive production. Background Art
[0002] Household appliance motor drivers are electronic control modules specifically used to control the operation of various motors in household appliances. Their core function is to adjust the speed, rotation direction, start and stop, etc. of the motor according to user operations or preset programs. Compared with industrial servo drivers, they pay more attention to cost, volume, and simplicity, but also need to meet reliability requirements;
[0003] In the prior art, there are many technical bottlenecks and practical application defects in the strength detection during the production of household appliance motor drivers. Traditional detection methods usually conduct drop resistance tests, seismic resistance tests, and compressive tests separately, and multiple independent devices are required to complete the detection of different projects. This decentralized detection method not only occupies a large amount of factory space and increases the equipment procurement cost, but also seriously affects the detection efficiency due to multiple clamping and positioning operations. Moreover, due to repeated positioning, the detection data will deviate. At present, most of the drop test devices on the market adopt a fixed-height drop mode, with difficult adjustment of the drop height and a single material for the impact platform, making it difficult to truly simulate the impact conditions of different materials such as cement floors, ceramic floors, and metal platforms that the driver may encounter during actual transportation and installation, resulting in a significant difference between the test results and the actual use environment. Summary of the Invention
[0004] (I) Technical Problems to be Solved
[0005] Aiming at the deficiencies of the prior art, the present invention provides a strength detection device for drive production. Through the designed drop detection bin and gantry, the device can automatically push the drivers that have fallen on the first metal plate and the second metal plate to directly below the gantry without manual transfer by the operator after high-altitude drop strength detection of the drivers. A hydraulic rod is provided at the top of the gantry, and the hydraulic rod drives the inclined panel to squeeze the driver downward to conduct a compressive test on the driver. Both can achieve the purpose of drive strength detection. The purpose of the drop test is to simulate accidental drop impacts during transportation and installation, while the compressive test is to test the anti-deformation ability of the housing and internal components. At the same time, a third electric push rod is provided below the interior of the drop detection box, and the third electric push rod can drive the top plate and the first metal plate to move up and down in the drop detection box, allowing the driver to conduct drop tests at different heights. Moreover, not only the first metal plate is provided on the top of the top plate, but also the second metal plate with a simulation plate can be provided. The top of the simulation plate simulates common floor materials including but not limited to cement floors, stone brick floors, and ceramic floors, simulating different situations of the driver under different drop environments, facilitating the operator to compare different drop data of the driver.

[0044] Embodiment Two:
[0045] Please refer to Figure 7 to - Figure 8 as shown:
[0046] A baffle 101 is welded to the top rear end of the fixed seat 1. The rear of the bottom of the fixed seat 1 is fixed to the hollow chamber 4 by bolts. The output end of the hollow chamber 4 is fixed to the motor 401 by bolts. An output shaft 403 is arranged at the output end of the motor 401. The outside of the output shaft 403 penetrates through the inside of the cam 404 and is welded and fixed. The surface of the cam 404 contacts the bottom of the inner plate 405. A high-frequency vibration plate 402 is welded to the middle of the top of the inner plate 405. The bottom of the inclined panel 302 contacts the top of the high-frequency vibration plate 402. One end of the output shaft 403 away from the motor 401 is rotatably connected to the middle of the left side inside the hollow chamber 4. The edge of the inner plate 405 is slidably connected to the inner wall of the hollow chamber 4. The middle of the bottom of the high-frequency vibration plate 402 is slidably connected to the middle of the upper part inside the hollow chamber 4.
[0047] In this embodiment: not only can the driver pushed by the push plate 206 to the left position of the high-frequency vibration plate 402 be moved to the center of the high-frequency vibration plate 402 through high-frequency vibration and the inclined surface of the inclined panel 302, facilitating the hydraulic rod 301 to conduct a compressive test on the driver, but also the vibration generated by the cam 404 driving the high-frequency vibration plate 402 can conduct a seismic test on the driver, reproducing the continuous vibration in the working environment.
[0048] In an alternative embodiment: the bottom of the inclined panel 302 is provided with an inclined surface from the lower front side to the upper rear side, and the inclination angle of the inclined surface of the inclined panel 302 is 12.5°.
[0049] In this embodiment: through high-frequency vibration and the inclined surface of the inclined panel 302, the driver is moved to the center of the high-frequency vibration plate 402, facilitating the hydraulic rod 301 to conduct a compressive test on the driver.
[0050] In an alternative embodiment: a connecting column is arranged between the high-frequency vibration plate 402 and the inner plate 405. A through hole is opened in the middle of the upper part inside the hollow chamber 4 from top to bottom, and the caliber of the through hole matches the cross-sectional diameter of the connecting column.
[0051] In this embodiment: the purpose of driving the high-frequency vibration plate 402 at the top of the hollow chamber 4 to move up and down cyclically with the cam 404 based on the output shaft 403 can be achieved.
[0052] Working principle: Before use, according to different models of the driver, replace the first metal plate 210 or the second metal plate 212 on the top of the top plate 208 to test the damage caused to the driver by dropping it in different environments. Open the first opening and closing door 203 below the front end face of the drop detection box 2, insert the first metal plate 210 or the second metal plate 212 into the drop detection box 2 through the first opening and closing door 203, and then place the first metal plate 210 or the second metal plate 212 on the top of the top plate 208. Rotate the threaded rods 211 on the left and right sides of the top plate 208, and the threaded rods 211 drive the limiting plate 209 at the bottom to move towards the top left and right ends of the first metal plate 210 or the second metal plate 212 until the limiting plate 209 presses the first metal plate 210 or the second metal plate 212. Then, according to different drivers, adjust the height of the top of the top plate 208. The third electric push rod 207 at the bottom of the top plate 208 is activated, and after reaching the set position, the third electric push rod 207 is closed. Close the first opening and closing door 203, and the preliminary preparation work of the drop detection box 2 is completed;
[0053] When in use, place the driver to be tested on the square through groove opened in the middle of the top of the drop detection box 2. At this time, the driver is supported by the sliding plate 201 closely attached to the inner wall above the drop detection box 2. When starting the test, the second electric push rod 205 drives the sliding plate 201 to retract outward, and the driver loses support and falls from top to bottom onto the simulation plate 213 on the top of the first metal plate 210 or the second metal plate 212 on the top of the top plate 208. The simulation plate 213 uses common floor materials including but not limited to cement floor, stone brick floor, ceramic floor, etc. to simulate different situations of the driver in different drop environments. After the drop test is completed, the third electric push rod 207 drives the top plate 208 to move upward until the height of the top of the top plate 208 is the same as the height of the top of the fixed seat 1 outside the drop detection box 2. The first electric push rod 202 on the front end face of the drop detection box 2 drives the push plate 206 at the output end to push the driver away from the top of the first metal plate 210 or the simulation plate 213 and out of the drop detection box 2. The second opening and closing door 204 on the rear end face of the drop detection box 2 is pushed open until the driver completely exits the drop detection box 2 and is at the front top position of the high-frequency vibration plate 402. Then, the first electric push rod 202 drives the push plate 206 to retract, and the third electric push rod 207 drives the top plate 208 to retract downward;
[0054] The driver is located at the front top of the high-frequency vibration plate 402. It needs to move to the center of the high-frequency vibration plate 402 under the high-frequency vibration generated by the high-frequency vibration plate 402 and the restriction of the inclined surface of the inclined panel 302. The hydraulic rod 301 in the middle of the top of the gantry 3 drives the inclined panel 302 at the output end to move downward until there is a certain gap between the bottom of the front side of the inclined panel 302 and the top of the driver. The distance of this gap is the same as the height exceeding the horizontal plane during the up-and-down cyclic vibration of the high-frequency vibration plate 402. Close the hydraulic rod 301, turn on the motor 401 on the front end face of the hollow chamber 4. The motor 401 drives the output shaft 403 at the output end to rotate. The cam 404 penetrated through the outside of the output shaft 403 rotates irregularly with the output shaft 403 as the base point. The inner plate 405 at the top of the cam 404 drives the high-frequency vibration plate 402 to move up and down cyclically and rapidly. At this time, under the influence of the high-frequency vibration of the high-frequency vibration plate 402, the driver frequently impacts the inclined panel 302 with an inclined surface. Therefore, the driver will slowly move along the inclined surface of the inclined panel 302 towards the center of the high-frequency vibration plate 402. After reaching the center, turn off the motor 401. During the movement, an earthquake resistance test is also carried out on the driver to reproduce the continuous vibration in the working environment. After turning off the motor 401, start the hydraulic rod 301 in the middle of the top of the gantry 3. The hydraulic rod 301 drives the inclined panel 302 to squeeze towards the top of the driver again to conduct a compressive test on the driver. After the test is completed, the hydraulic rod 301 drives the inclined panel 302 to retract upward, and the operator can take the tested driver from behind the fixed seat 1.
