Description

Technical Field

[0001] This utility model belongs to the technical field of testing devices, and specifically relates to a stator shell strength testing device. Background Technology

[0002] Currently, Chinese utility model patent CN217304690U discloses a stator housing strength testing device for automotive starters. Although this testing device is driven by a hydraulic cylinder and can move the pressure block and pressure sensor up and down, there are other problems in its use. For example, the positioning effect of the stator housing is poor. In order to prevent the stator housing from shifting during the extrusion test, a limiting block for housing adaptation is installed at the top of the bottom. However, the adaptation effect of the limiting block is poor, and it can only be used for housing of a single specification. If the inner diameter of the housing is too large or too small, it will affect the positioning effect. Moreover, it is not convenient to perform multi-point testing. In order to ensure the comprehensiveness of the testing effect, in addition to the extrusion test at the center position, the outer perimeter needs to be tested again. When changing the test point of the housing, it is necessary to manually loosen it first, then adjust the position and tighten it again, which reduces the work efficiency of personnel. Utility Model Content

[0003] The purpose of this invention is to provide a stator shell strength testing device, which has the advantages of improving the positioning effect of the stator shell and facilitating multi-point strength testing.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a stator shell strength testing device, comprising a first fixed frame, a bidirectional screw rotatably connected inside the first fixed frame, two first screw plates threadedly connected to the surface of the bidirectional screw, a first positioning plate and a second positioning plate respectively bolted to the top of the two first screw plates, a positioning block installed on one side of the second positioning plate, a second fixed frame provided on the top of the first fixed frame, connecting plates symmetrically installed between the top of the first fixed frame and the second fixed frame, a testing mechanism provided on the front of the second fixed frame, a threaded rod rotatably connected inside the second fixed frame, and a second screw plate threadedly connected to the surface of the threaded rod.

[0005] The above technical solution can improve the positioning effect of the stator housing, is applicable to housings of different lengths, reduces the adjustment burden and time spent by personnel, improves the stability of the housing inspection process, facilitates multi-point strength testing, is simple and convenient to operate, eliminates the burden of repeated disassembly and assembly by personnel, speeds up the inspection efficiency, and has high practicality.

[0006] The present invention is further configured such that the detection mechanism includes a hydraulic press, the hydraulic press is bolted through to the top of the second screw plate, a pressure block is installed at the output end of the hydraulic press, and a pressure sensor is installed at the bottom of the pressure block.

[0007] The above technical solution involves setting up a hydraulic press, a pressure block, and a pressure sensor. After connecting to an external display screen controller, a specified intensity value can be input. Then, the hydraulic press is turned on to move the pressure block downward. After the pressure block moves downward, it will cause the pressure sensor to press against the stator housing and continuously increase the pressure value until the pressure sensor reaches the input specified intensity value.

[0008] The present invention is further configured such that a slide rail is bolted inside the first fixed frame, and a slider that is slidably connected to the slide rail is welded to the bottom of the first screw plate.

[0009] The above technical solution allows for the limitation of the first screw plate by setting up a slide rail and a slider, preventing the first screw plate from flipping over during left and right movement.

[0010] The present invention is further configured such that two guide rods are installed between the two connecting plates, and through holes are provided inside the first positioning plate and the second positioning plate.

[0011] The above technical solution enables the guide rod to quickly guide the stator housing, ensuring that the stator housing is placed at the center point after insertion.

[0012] The present invention is further configured such that a positioning rod is provided through one side of the second screw plate, and both ends of the positioning rod are welded to the inside of the second fixing frame.

[0013] The above technical solution allows for the positioning of the second screw plate, preventing it from rotating during left and right movements.

[0014] The present invention is further configured such that a first throttle is installed at the other end of the bidirectional screw, and a second throttle is installed at the other end of the threaded rod.

[0015] The above technical solution allows for easy rotation of the bidirectional screw and threaded rod by the setting of the first and second throttles.

[0016] The present invention is further provided that a moisture-proof pad is bolted to the bottom of the first fixing frame.

[0017] By adopting the above technical solution, the moisture-proof effect of the bottom of the first fixing frame can be improved by setting a moisture-proof pad.

[0018] The present invention is further provided that a storage frame is installed on one side of the connecting plate.

[0019] The above technical solution allows for the temporary storage of tools required for the device by setting up storage boxes.

[0020] The present invention is further provided that the front of the second fixing frame is integrally stamped with scale lines.

[0021] The above technical solution allows for precise observation and control of the left and right movement distance of the second screw plate by setting the scale lines.

[0022] The present invention is further configured such that the first positioning plate, the second positioning plate, and the positioning block are all made of stainless steel.

[0023] The above technical solution features high strength, low density, and excellent corrosion resistance in the first positioning plate, the second positioning plate, and the positioning block.

[0024] In summary, this utility model has the following beneficial effects:

[0025] 1. By first placing the stator housing onto the first fixed frame between the two guide rods, with the open side of the housing facing the second positioning plate, and then holding the first throttle to rotate the bidirectional screw, the bidirectional screw will drive the two first screw plates to move inward synchronously through the cooperation of the slide rail and the slider. When the first screw plates move, they will drive the first positioning plate and the positioning block to push the housing towards the center and clamp it in place. This can improve the positioning effect of the stator housing, is suitable for housings of different lengths, reduces the adjustment burden and time spent by personnel, and improves the stability of the housing inspection process.

[0026] 2. By starting the hydraulic press, the pressure block and pressure sensor move downwards. The pressure sensor will press against the stator housing and feed the information back to the external display controller. When it is necessary to switch the test point, hold the second throttle and rotate the threaded rod. When the threaded rod rotates, it will move the second screw plate to the left or right with the help of the positioning rod. When the second screw plate moves, it will move the test mechanism together, which can facilitate multi-point strength testing. The operation is simple and convenient, eliminating the burden of repeated disassembly and assembly for personnel, speeding up the testing efficiency, and making it highly practical.

A first positioning plate 6 and a second positioning plate 7 are respectively bolted to the top of the two first screw plates 5. A positioning block 8 is installed on one side of the second positioning plate 7. The stator housing is first placed on the first fixed frame 1 between two guide rods 14, with the open side of the housing facing the second positioning plate 7. Then, the first throttle 16 is held by hand to rotate the bidirectional screw 4. When the bidirectional screw 4 rotates, it drives the two first screw plates 5 to move inward synchronously through the cooperation of the slide rail 12 and the slider 13. When the first screw plates 5 move, they drive the first positioning plate 6 and the positioning block 8 to push the housing towards the center and clamp it. This improves the positioning effect of the stator housing, is suitable for housings of different lengths, reduces the adjustment burden and time spent by personnel, and improves the stability of the housing testing process.

[0034] refer to Figure 1 The testing mechanism 9 includes a hydraulic press 91, which is bolted to the top of the second screw plate 11. A pressure block 92 is installed at the output end of the hydraulic press 91, and a pressure sensor 93 is installed at the bottom of the pressure block 92. Through the configuration of the hydraulic press 91, the pressure block 92, and the pressure sensor 93, it can be connected to an external display screen controller to input a specified intensity value. Then, the hydraulic press 91 is turned on to move the pressure block 92 downward. After the pressure block 92 moves downward, it will cause the pressure sensor 93 to press against the stator housing and continuously increase the pressure value until the pressure sensor 93 reaches the input specified intensity value.

[0035] refer to Figure 1 and Figure 2The first fixed frame 1 is bolted with a slide rail 12 inside. The bottom of the first screw plate 5 is welded with a slider 13 that is slidably connected to the slide rail 12. By setting the slide rail 12 and the slider 13, the first screw plate 5 can be limited to prevent it from flipping over during left and right movement.

[0036] refer to Figure 3 Two guide rods 14 are installed between the two connecting plates 3. The first positioning plate 6 and the second positioning plate 7 are both provided with through holes. The guide rods 14 can quickly guide the stator housing, so that the stator housing will be in the center position after being placed.

The first positioning plate 6, the second positioning plate 7, and the positioning block 8 have the characteristics of high strength, low density, and excellent corrosion resistance.

[0039] Brief description of the usage process: First, place the stator housing on the first fixed frame 1 between the two guide rods 14, with the open side of the housing facing the second positioning plate 7. Then, hold the first throttle 16 to drive the bidirectional screw 4 to rotate.

A threaded rod 10 is rotatably connected inside the second fixed frame 2. A second screw plate 11 is threadedly connected to the surface of the threaded rod 10. By starting a hydraulic press 91, the pressure block 92 and pressure sensor 93 are moved downward. The downward movement of the pressure sensor 93 will squeeze the stator housing and feed the information back to the external display screen controller. When it is necessary to switch the testing point, the second throttle 17 is held by hand to rotate the threaded rod 10. When the threaded rod 10 rotates, it will drive the second screw plate 11 to move to the left or right with the cooperation of the positioning rod 15. When the second screw plate 11 moves, it will drive the testing mechanism 9 to move together. This device facilitates multi-point strength testing, is simple and convenient to operate, eliminates the burden of repeated disassembly and assembly by personnel, speeds up the testing efficiency, and has high practicality.

[0042] refer to Figure 2 A positioning rod 15 is provided through one side of the second screw plate 11. Both ends of the positioning rod 15 are welded to the inside of the second fixing frame 2. The positioning rod 15 can limit the second screw plate 11 and prevent the second screw plate 11 from rotating during left and right movement.

[0043] refer to Figure 1 and Figure 2 The other end of the bidirectional screw 4 is equipped with a first throttle 16, and the other end of the threaded rod 10 is equipped with a second throttle 17.

[0045] refer to Figure 1 The front of the second fixed frame 2 is integrally stamped with scale lines 20. The scale lines 20 make it easy for personnel to accurately observe and control the left and right movement distance of the second screw plate 11.

[0046] Brief description of the usage process: By starting the hydraulic press 91, the pressure block 92 and pressure sensor 93 are moved down. The pressure sensor 93 will press against the stator housing and feed the information back to the external display controller. When it is necessary to switch the detection point, hold the second throttle 17 to rotate the threaded rod 10. When the threaded rod 10 rotates, it will drive the second screw plate 11 to move to the left or right with the cooperation of the positioning rod 15. When the second screw plate 11 moves, it will drive the detection mechanism 9 to move together.
