Description

Technical Field

[0001] This utility model relates to the field of motor parts testing technology, and in particular to a testing fixture for the production of motor parts. Background Technology

[0002] Motor component testing refers to the process of verifying the geometric dimensions, mechanical properties, electrical characteristics, and functional reliability of motor components through systematic measurement, testing, and analysis. Its core objective is to ensure that the components meet design standards, assembly requirements, and operating performance. A testing fixture for motor component production is a special tool or equipment used in the motor component production process to perform rapid, accurate, and standardized testing of parts.

[0003] Existing testing fixtures for motor parts rely heavily on manual operation. Testers measure parts by hand using handheld testing tools, which is not only inefficient but also prone to inaccurate test results due to human error. Utility Model Content

[0004] The purpose of this utility model is to provide a testing fixture for the production of motor parts, so as to solve the defect that the existing testing fixtures for motor parts are not convenient for automatic testing.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a testing fixture for the production of motor parts, including a base plate;

[0006] A side plate is fixed to one side of the top of the base plate, and a support plate is fixed to the top of the side plate. A detection structure is provided inside the support plate. The detection structure includes a first movable plate disposed on one side inside the support plate, and a second movable plate disposed on the other side inside the support plate. A connecting plate is fixed to the top of the first and second movable plates above the support plate, and a lifting plate is fixed to the bottom of the first and second movable plates below the support plate. Sliding grooves are provided on both sides of the support plate outside the first and second movable plates, and through grooves are provided inside the first and second movable plates.

[0007] A positioning structure is fixed at the top of the base plate.

[0008] Preferably, teeth are fixed on one side of the through groove, a motor is fixed on one side of the top of the support plate, a rotating shaft is fixed at the output end of the motor, gears are fixed on the outer side of the rotating shaft inside the through groove, a detector is installed at the top of the lifting plate, a detection hole is provided at the middle position inside the lifting plate, and a detection head is fixed at the bottom of the detector inside the detection hole.

[0009] Preferably, the first movable plate and the second movable plate are symmetrically distributed inside the support plate, and the first movable plate and the connecting plate are slidably connected to the support plate through grooves.

[0010] With the above structure, the first and second moving plates are symmetrically distributed inside the support plate during use, so that the force on both is balanced during movement, avoiding tilting or displacement due to excessive force on one side. In addition, the slide groove guides and limits the movement of the first moving plate and the connecting plate, further constraining their movement trajectory and ensuring that they can only move up and down along the direction of the slide groove, without shaking in other directions, thus ensuring the stability of the entire detection structure during operation.

[0011] Preferably, the teeth are evenly spaced on one side inside the through groove, and the gear is meshed with the first moving plate and the second moving plate through the teeth.

[0012] With the above structure, when the motor starts and drives the shaft to rotate, the two sets of gears will rotate synchronously. Through the meshing transmission of the gears and teeth, the first and second moving plates can be driven to move stably up and down in the slide groove, thereby driving the lifting plate and detector to rise and fall, so that the detection head can accurately contact the motor components to complete the detection, ensuring the stability of the lifting process and the accuracy of the detection.

[0013] Preferably, the positioning structure includes a testing platform fixed to the top of the base plate, an accessory placement slot is provided at the middle position of the top of the testing platform, damping telescopic rods are installed at the edges of the top of the testing platform, buffer springs are installed on the outer side of the damping telescopic rods, positioning rods are fixed on both sides of the bottom end of the lifting plate, and positioning holes are provided on both sides inside the testing platform.

[0014] Preferably, the damping telescopic rods are evenly distributed at the top of the testing platform, the top of the damping telescopic rods are fixedly connected to the bottom of the lifting plate, and the lifting plate and the damping telescopic rods form a telescopic structure through a buffer spring.

[0015] With the above structure, during use, when the lifting platform descends, it compresses the damping telescopic rod and the buffer spring on its outer side. The damping telescopic rod uses its damping characteristics to slow down the descent speed of the lifting platform, while the buffer spring further absorbs the impact force of the descent through its own elastic deformation. The combination of the two can effectively prevent the detection head from violently colliding with the motor components, protecting the surface of the motor components from scratches and damage, and reducing the probability of the detection head being damaged by impact.

[0016] Preferably, the positioning rods are symmetrically distributed on both sides of the bottom end of the lifting plate, and the positioning holes are symmetrically distributed on both sides of the top end of the testing platform, with each positioning rod corresponding to a positioning hole.

[0017] With the above structure, when the lifting plate descends during use, the positioning rod will precisely insert into the corresponding positioning hole. This further calibrates the relative position of the lifting plate and the testing platform, ensuring that the testing head mounted on the lifting plate can accurately align with the testing area of ​​the motor component placed in the component placement slot on the testing platform, avoiding inaccurate testing due to minor deviations in component placement or lifting plate movement.

[0018] The present invention provides a testing fixture for the production of motor parts, the advantages of which are:

[0019] With the detection structure in place, the first and second moving plates are slidably connected to the support plate via a slide groove. Combined with the meshing transmission of gears and teeth, the lifting process of the lifting plate is stable and without deviation, ensuring that the detection head can accurately align with the detection part of the motor parts.

[0020] By incorporating a positioning structure, the initial positioning of motor components is achieved through the component placement slot. The alignment of the positioning rod and the positioning hole further calibrates the position, avoiding detection errors caused by component placement deviations and significantly improving the reliability of the detection results. When the lifting plate descends, the damping telescopic rod and buffer spring are compressed, utilizing their elastic buffering effect to slow down the descent speed and prevent the detection head from violently colliding with the motor components. This effectively protects the surface of the components from scratches and damage, while also reducing the probability of the detection head being damaged by impact. Attached Figure Description

[0027] 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 protection scope of the present utility model.

[0028] Please see Figure 1-5 The present invention provides a testing fixture for the production of motor parts, including a base plate 1.

[0029] Reference Figures 2-5 As shown, a side plate 2 is fixed to one side of the top of the base plate 1, and a support plate 3 is fixed to the top of the side plate 2. A detection structure 4 is provided inside the support plate 3. The detection structure 4 includes a first movable plate 401 located on one side of the support plate 3, and a second movable plate 402 located on the other side of the support plate 3. A connecting plate 403 is fixed to the top of the first movable plate 401 and the second movable plate 402 above the support plate 3. A lifting plate 404 is fixed to the bottom of the first movable plate 401 and the second movable plate 402 below the support plate 3. Sliding grooves 405 are provided on both sides of the support plate 3 outside the first movable plate 401 and the second movable plate 402. Through grooves 406 are provided inside the first movable plate 401 and the second movable plate 402. A tooth 407 is fixed to one side of the through groove 406. A motor 408 is fixed to one side of the top, and a rotating shaft 409 is fixed to the output end of the motor 408. Gears 410 are fixed to the outer side of the rotating shaft 409 inside the through groove 406. A detector 411 is installed at the top of the lifting plate 404. A detection hole 412 is provided in the middle position inside the lifting plate 404. A detection head 413 is fixed to the bottom end of the detector 411 inside the detection hole 412. The first moving plate 401 and the second moving plate 402 are symmetrically distributed inside the support plate 3. The first moving plate 401 and the connecting plate 403 are slidably connected to the support plate 3 through the sliding groove 405. The teeth 407 are evenly distributed on one side inside the through groove 406. The gears 410 are meshed with the first moving plate 401 and the second moving plate 402 through the teeth 407.

[0030] By starting the motor 408, the rotating shaft 409 is driven to rotate, which in turn causes the two sets of gears 410 to rotate synchronously. The gears 410 are meshed with the teeth 407 on one side of the through groove 406 inside the first moving plate 401 and the second moving plate 402. The rotation of the gears 410 drives the first moving plate 401 and the second moving plate 402 to move up and down inside the slide groove 405, ensuring the stability of the movement process. The up and down movement of the first moving plate 401 and the second moving plate 402 drives the lifting plate 404 and the detector 411 installed on its top to rise and fall together. When the lifting plate 404 descends, the detection head 413 at the bottom of the detector 411 contacts the motor accessory placed on the accessory placement groove 502 through the detection hole 412, thereby completing the detection work.

[0031] Reference Figures 1-5 As shown, a positioning structure 5 is fixed to the top of the base plate 1. The positioning structure 5 includes a testing platform 501 fixed to the top of the base plate 1. A component placement slot 502 is provided at the middle position of the top of the testing platform 501. Damping telescopic rods 503 are installed at the edges of the top of the testing platform 501. Buffer springs 504 are installed on the outer side of the damping telescopic rods 503. Positioning rods 505 are fixed to both sides of the bottom end of the lifting plate 404. Positioning holes 506 are provided on both sides inside the testing platform 501. The damping telescopic rods 503 are evenly distributed at the top of the testing platform 501. The top of the damping telescopic rods 503 is fixedly connected to the bottom end of the lifting plate 404. The lifting plate 404 and the damping telescopic rods 503 form a telescopic structure through the buffer springs 504. The positioning rods 505 are symmetrically distributed on both sides of the bottom end of the lifting plate 404. The positioning holes 506 are symmetrically distributed on both sides of the top of the testing platform 501. The positioning rods 505 and the positioning holes 506 correspond one-to-one.

[0032] The motor components are placed in the component placement slot 502 at the top of the testing platform 501 for initial positioning. During the descent of the lifting plate 404, the positioning rod 505 at its bottom end is inserted into the corresponding positioning hole 506 inside the testing platform 501 to further ensure the precise alignment of the motor components and the testing head 413. When the lifting plate 404 descends, it compresses the damping telescopic rod 503 and the buffer spring 504, thereby slowing down the descent speed and avoiding impact damage to the motor components and the testing head 413. It can also assist the lifting plate 404 in resetting after the test is completed.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
