Description
Technical Field
[0001] This utility model relates to the field of locomotive motor testing technology, and in particular to a rapid testing fixture for locomotive motor Hall sensors. Background Technology
[0002] Hall effect sensors are key components in locomotive motors, used to detect motor speed and position. Their performance directly affects the operating status and safety of the locomotive motor.
[0003] Currently, the detection of Hall sensors for locomotive motors is mostly done manually by connecting the detection equipment. This method has the following problems: low detection efficiency, requiring manual connection of each sensor lead, cumbersome operation, poor contact during the detection process, affecting detection accuracy, lack of unified detection standards and fixed detection platforms, poor consistency of detection results, and safety hazards in manual operation, especially in high-voltage detection environments.
[0004] Therefore, this utility model proposes a rapid detection tooling for locomotive motor Hall sensors. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapid detection fixture for locomotive motor Hall sensors.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a rapid detection fixture for a locomotive motor Hall sensor, comprising a detection frame assembly, the detection frame assembly being composed of a concave frame and clamping frames disposed on both sides of the top, and further comprising:
[0007] The clamping assembly consists of a pressing plate and a clamping disc disposed within a clamping frame. The clamping disc is disposed through the clamping frame on the side near the concave frame. A spring is disposed between the clamping disc and the clamping frame. Multiple clamping discs are disposed in total, and the distance between two adjacent clamping discs is equal.
[0008] Furthermore, a sliding rod penetrating the clamping frame is provided on the other side of the extrusion plate, and a deformation component is provided between the extrusion plate and the clamping frame.
[0009] The beneficial effects of adopting the above-mentioned further solution are: the slide bar on the other side of the extrusion plate passes through the clamping frame, ensuring the stable movement of the extrusion plate and avoiding deviation that affects the clamping accuracy; the deformation component between the extrusion plate and the clamping frame can adaptively deform with the clamping force, ensuring both firm clamping and buffering pressure to prevent excessive extrusion from damaging the sensor; at the same time, it is compatible with sensors of different specifications, improving the tooling versatility and operational stability, and ensuring a reliable and efficient detection process.
[0010] Furthermore, the deformation component is made of deformation elastic steel, and rectangular fault-tolerant holes and arc-shaped fault-tolerant holes are sequentially formed on the deformation elastic steel.
[0011] The beneficial effects of adopting the above-mentioned further solution are as follows: the deformation component uses deformation elastic steel, which provides stable buffer by utilizing its good elasticity and toughness. The rectangular fault-tolerant hole and the arc-shaped fault-tolerant hole are matched to guide the elastic steel to deform in an orderly manner, which not only ensures sufficient deformation space to adapt to different clamping requirements, but also maintains structural strength to avoid excessive deformation, realizes adaptive adjustment of clamping force, protects the sensor from damage, enhances the durability and adaptability of tooling, and improves detection stability.
[0012] Furthermore, each of the clamping frames is provided with an electric push rod on the side that is far apart from each other. The output end of the electric push rod is connected to the slide rod. There are a total of four electric push rods, and the four electric push rods are distributed in a rectangular shape on the two clamping frames.
[0013] The beneficial effects of adopting the above-mentioned further solution are as follows: the electric push rod on the outside of the clamping frame is connected to the slide rod to provide power for clamping. The four electric push rods distributed in a rectangular shape work synchronously to evenly transmit the extrusion force to the extrusion plate, ensuring that the clamping process is stable and unbiased. Electric control realizes automated clamping, avoiding the problem of uneven force due to manual operation. This not only improves the convenience of operation, but also ensures that the clamping force is stable and controllable. It is also compatible with sensors of different specifications, improving detection efficiency and reliability.
[0014] Furthermore, each of the two clamping frames is provided with a mounting bracket at one end that is far apart from each other. There are a total of four mounting brackets, and the four mounting brackets are arranged in pairs, symmetrical to each other at the center of the concave frame.
[0015] The beneficial effects of adopting the above-mentioned further solution are as follows: the mounting brackets at both ends of the two clamping brackets are symmetrically distributed, forming two sets of fixed support points with the center of the concave bracket as the reference. This symmetrical design ensures that the overall force is balanced after the tooling is installed, avoiding tilting due to unstable fixing. The four mounting brackets provide multiple fixing points, enhancing the connection stability between the tooling and the worktable, preventing displacement due to vibration during testing, ensuring clamping accuracy and testing stability, and facilitating flexible installation according to the scenario, thus improving the applicability of the tooling.
[0016] Furthermore, an anti-slip pad is provided on the side of the clamping disc away from the spring, and the size of the anti-slip pad is adapted to the size of the clamping disc.
[0017] The beneficial effects of adopting the above-mentioned further solution are: the anti-slip pad on the surface of the clamping plate is in direct contact with the sensor, which effectively prevents the sensor from sliding during the detection process by increasing the coefficient of friction. The size of the anti-slip pad is adapted to the clamping plate to ensure full fit, which not only enhances the clamping stability, but also avoids damage to the sensor surface caused by rigid contact. Its flexible material can also buffer the clamping force, adapt to different sensor shapes, and improve the protection effect of the tooling on the sensor and the detection reliability.
[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0019] In this invention, the clamping assembly uses a pressing plate to push multiple equidistant clamping discs, which, in conjunction with the elastic force of springs, achieve flexible clamping of the sensor. The springs can buffer the clamping force and prevent rigid compression from damaging the sensor. The multiple equidistant clamping discs ensure uniform force distribution and prevent sensor displacement. This structure can stably clamp sensors of different specifications and can adapt to slight size differences through elastic adjustment, thereby improving clamping reliability and detection stability.

Multiple clamping discs 23 are disposed, and the distance between two adjacent clamping discs 23 is equal. Through the clamping assembly 2, the pressing plate 21 pushes multiple equidistantly distributed clamping discs 23, and the elastic force of the springs 231 achieves flexible clamping of the sensor. The springs 231 can buffer the clamping force and avoid rigid compression damage to the sensor. Multiple equidistant clamping discs 23 ensure uniform force distribution and prevent sensor displacement. This structure can stably clamp sensors of different specifications and can adapt to slight size differences through elastic adjustment, thereby improving clamping reliability and detection stability.
[0032] A sliding rod 22 is provided on the other side of the extrusion plate 21, which passes through the clamping frame 12. A deformation component 3 is provided between the extrusion plate 21 and the clamping frame 12. The sliding rod 22 on the other side of the extrusion plate 21 passes through the clamping frame 12 to ensure the stable movement of the extrusion plate 21 and avoid deviation that affects the clamping accuracy. The deformation component 3 between the extrusion plate 21 and the clamping frame 12 can adaptively deform according to the clamping force, which not only ensures a firm clamping, but also buffers the pressure and prevents excessive extrusion from damaging the sensor. At the same time, it is compatible with sensors of different specifications, improves the versatility of the tooling and the stability of operation, and ensures that the detection process is reliable and efficient.
[0033] The deformation component 3 is composed of deformable elastic steel 31. Rectangular tolerance holes 32 and arc-shaped tolerance holes 33 are sequentially formed on the deformable elastic steel 31. The deformation component 3 uses deformable elastic steel 31 to provide stable buffering by utilizing its good elasticity and toughness. The rectangular tolerance holes 32 and arc-shaped tolerance holes 33 cooperate to guide the elastic steel to deform in an orderly manner, which not only ensures sufficient deformation space to adapt to different clamping requirements, but also maintains structural strength to avoid excessive deformation, realizes adaptive adjustment of clamping force, protects the sensor from damage, enhances the durability and adaptability of the tooling, and improves detection stability.
[0034] Electric push rods 121 are provided on the opposite sides of the clamping frames 12. The output end of the electric push rods 121 is connected to the slide rod 22. There are four electric push rods 121 in total, and the four electric push rods 121 are distributed in a rectangular shape on the two clamping frames 12. The electric push rods 121 on the outer side of the clamping frame 12 are connected to the slide rod 22 to provide power for clamping. The four rectangularly distributed electric push rods 121 work synchronously to evenly transmit the extrusion force to the extrusion plate 21, ensuring that the clamping process is stable and without off-center load. Electric control realizes automated clamping, avoiding the problem of uneven force due to manual operation. It not only improves the convenience of operation, but also ensures that the clamping force is stable and controllable. It is compatible with different specifications of sensors, enhancing detection efficiency and reliability.
[0035] Each of the two clamping frames 12 has a mounting bracket 122 at one of its far ends. There are four mounting brackets 122 in total, and the four mounting brackets 122 are arranged in pairs symmetrically around the center of the concave frame 11. The mounting brackets 122 at both ends of the two clamping frames 12 are symmetrically distributed, forming two sets of fixed support points with the center of the concave frame 11 as the reference. This symmetrical design ensures that the overall force is balanced after the tooling is installed, avoiding tilting due to unstable fixing. The four mounting brackets 122 provide multiple fixing points, enhancing the connection stability between the tooling and the worktable, preventing displacement due to vibration during testing, ensuring clamping accuracy and testing stability, and facilitating flexible installation according to the scenario, thus improving the applicability of the tooling.
[0036] An anti-slip pad 232 is provided on the side of the clamping plate 23 away from the spring 231. The size of the anti-slip pad 232 is adapted to the size of the clamping plate 23. The anti-slip pad 232 on the surface of the clamping plate 23 is in direct contact with the sensor. By increasing the coefficient of friction, it effectively prevents the sensor from sliding during the detection process. The size of the anti-slip pad 232 is adapted to the clamping plate 23 to ensure a full fit, which not only enhances the clamping stability, but also avoids damage to the sensor surface caused by rigid contact. Its flexible material can also buffer the clamping force, adapt to different sensor shapes, and improve the protection effect of the tooling on the sensor and the reliability of detection.
