Description

Technical Field

[0001] This utility model relates to the field of sensor detection technology, specifically to a sensor external housing strength testing device. Background Technology

[0002] The temperature sensor housing is a type of metal stamping part. The product undergoes stretching and stamping processes to ultimately become the main component of the required temperature sensor.

[0003] During sensor manufacturing, random sampling tests of the strength of the outer casing are required to ensure overall production quality. However, existing strength testing equipment typically uses stamping to directly apply pressure to the casing, with workers visually observing its strength. This testing method cannot accurately determine the time it takes for the casing to break. Furthermore, temperature sensors are generally used in high-temperature environments, and existing strength testing equipment cannot simulate the sensor casing's operation under high temperatures or its resistance to stamping at high temperatures. Utility Model Content

[0004] The purpose of this invention is to provide a sensor external housing strength testing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A sensor external housing strength testing device includes a strength testing instrument body, a testing head, and auxiliary testing components. A hydraulic push rod is provided in the middle of the strength testing instrument body, the testing head is provided at the output end of the hydraulic push rod, a laser emitter is installed in the inner groove in the middle of the testing head, and auxiliary testing components are provided below the testing head. The auxiliary detection component includes a placement plate, limiting blocks, a detection element, and a heating element. The placement plate has three limiting blocks fixedly connected to its top. The detection element is installed inside the placement plate, and a laser receiver is located below the detection element.

[0006] Furthermore, the placement plate is fixed to the middle of the bottom side of the strength testing instrument body.

[0007] Furthermore, the heating element is an electric heating wire, which is arranged in a ring on the inner wall of the placement tray.

[0008] Furthermore, the detection element is a temperature sensor.

[0009] Furthermore, a hollow groove is provided in the center of the placement tray.

[0010] Furthermore, the excitation emitter in the middle of the detection head and the laser receiver are on the same vertical line.

[0011] Furthermore, a connecting frame is provided above the detection head, and the detection head is fixedly connected to the output end of the hydraulic push rod through the connecting frame.

[0012] Furthermore, a groove is provided in the middle of the detection head, and the excitation emitter is disposed inside the groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The strength testing device provided by this utility model is different from the existing testing methods. Its testing head uses an exciter and a laser receiver inside the auxiliary testing component to monitor the fracture time of the sensor's outer shell in real time, so as to quickly know how much pressure the shell is subjected to before it breaks. 2. The auxiliary detection component of this utility model is equipped with a heating element. After the heating element is heated, the local temperature of the plate increases. After the detection component reaches the specified temperature, the detection head is pushed by the hydraulic push rod to detect, thereby determining whether the strength of the sensor's outer shell is weakened in a high-temperature environment.

[0016] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0017] like Figure 1-3As shown, a sensor external housing strength testing device includes a strength testing instrument body 1, a testing head 2, and an auxiliary testing component 4. A hydraulic push rod 7 is provided in the middle of the strength testing instrument body 1, and the testing head 2 is located at the output end of the hydraulic push rod 7. A laser emitter is installed in the inner groove of the middle of the testing head 2, and the auxiliary testing component 4 is provided below the testing head 2. The strength testing device provided differs from existing testing methods. Its testing head 2 uses the laser emitter and the laser receiver 6 inside the auxiliary testing component 4 to monitor the fracture time of the sensor external housing in real time, thereby quickly determining the pressure under which the housing breaks. like Figure 2-3 As shown, the auxiliary detection component 4 includes a placement plate 401, a limiting block 402, a detection element 403, and a heating element 404. The placement plate 401 has three limiting blocks 402 fixedly connected to its top. The detection element 403 is installed inside the placement plate 401, and a laser receiver 6 is installed inside the placement plate 401. The heating element 404 is installed inside the auxiliary detection component 4. After the heating element 404 heats up, the local temperature of the placement plate 401 increases. After the detection element 403 detects that the temperature has reached the specified temperature, the detection head 2 is pushed by the hydraulic push rod 7 to detect, thereby determining whether the strength of the sensor's outer shell has weakened in a high-temperature environment.

[0018] The placement plate 401 is fixed to the middle of the bottom side of the main body 1 of the strength tester. The placement plate 401 itself is made of metal, specifically high carbon high chromium steel, which has high strength.

[0019] In one implementation, the heating element 404 is an electric heating wire, which is distributed in a ring on the inner wall of the placement plate 401. After the electric heating wire is energized, it continues to heat up. Once the temperature reaches 50-70 degrees, the operator can choose to turn it off.

[0020] Note: If the casing to be tested is made of plastic, the temperature should not be too high.

[0021] In one implementation, the detection element 403 is a temperature sensor. The temperature sensor can transmit the data to the terminal when it detects the greenhouse. Once the temperature reaches the specified requirement, the heating element 404 can be manually turned off.

[0022] In one embodiment, a hollow groove 5 is provided in the middle of the placement plate 401. The hollow groove 5 is used to stimulate the irradiation of the emitter and the laser receiver 6 after the detection head 2 descends.

[0023] In one implementation, the excitation emitter in the middle of the detection head 2 and the laser receiver 6 are on the same vertical line. After the detection head 2 breaks the outer shell, the laser receiver 6 can receive the laser emitted by the emitter, and the background data can be displayed.

[0024] In one implementation, a connecting frame 3 is provided above the detection head 2. The detection head 2 is fixedly connected to the output end of the hydraulic push rod 7 through the connecting frame 3. The connecting frame 3 is used for the installation of the detection head 2.

[0025] In one embodiment, a groove is provided in the middle of the detection head 2, and the excitation emitter is disposed inside the groove. The height of the metal detection head 2 is greater than that of the excitation emitter. When stamping, the detection head 2 will stamp the outer shell, while the excitation emitter itself will not be damaged.

[0026] Working principle: When the sensor external housing strength testing device is in use, the external housing is first placed in the middle of the placement plate 401 of the auxiliary testing component 4 and limited by the limiting block 402 to prevent movement. Then, the heating element 404 is activated to raise the temperature of the placement plate 401. At this time, the testing element 403 detects the temperature. Then, the hydraulic push rod 7 is activated to lower the testing head 2 to press the sensor external housing for testing. This is the working principle of the sensor external housing strength testing device.

[0027] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
