[0002] After the motor is manufactured, high and low temperature testing is an indispensable and important process. This test aims to comprehensively test the motor's performance and stability under different extreme temperature conditions. In high-temperature environments, the electronic components and insulation materials inside the motor face higher thermal stress, which may lead to performance degradation or even failure. In low-temperature environments, the motor's lubricant may thicken, affecting the operational flexibility of mechanical parts. By simulating various ambient temperatures that may be encountered in actual use, potential problems can be identified in time, ensuring that the motor will not fail due to drastic temperature changes, thus enabling stable and reliable operation in various complex and variable temperature environments.

[0003] However, during this process, due to the need to conduct high and low temperature tests, the test objects are at risk of explosion. As a result, when working in the test chamber, the safety of the testing personnel and equipment around the test chamber is at great risk. Utility Model Content

Detailed Implementation

[0033] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0034] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0035] Please see Figures 1 to 5 This utility model provides a manual testing device for high and low temperature testing without opening the chamber door, comprising a support base 1, a high and low temperature chamber 2 mounted on the upper side of the support base 1, a circular hole 3 on the top of the high and low temperature chamber 2, a sound detection sensor 4 mounted on the top wall of the high and low temperature chamber 2, a camera unit 5 mounted on one side of the sound detection sensor 4, a heat exchange assembly mounted on the high and low temperature chamber 2, and a clamping component mounted inside the high and low temperature chamber 2.

[0036] Furthermore, a control panel 6 is installed on one side of the high and low temperature chamber 2; the sound detection sensor 4 and the camera unit 5 are both connected to the control panel 6 via signals.

[0037] Using the above scheme: When conducting high and low temperature tests on the motor, the motor is first fixed on the clamping device, and then the motor is sent into the designated position in the high and low temperature chamber 2. After the motor is fixed in place by the clamping device, the high and low temperature chamber 2 is used to change the temperature inside the chamber, thereby conducting temperature tests on the motor. During the test, the camera unit 5 monitors whether the motor is deformed, and at the same time, the sound detection sensor 4 listens for any abnormal sounds emitted by the motor. These abnormalities may indicate that the motor is at risk of explosion. If the data detected by the camera unit 5 or the sound detection sensor 4 exceeds the safe range, the camera unit 5 or the sound detection sensor 4 will send a signal to the control panel 6. After receiving the signal, the control panel 6 will activate the heat exchange component to adjust the temperature inside the chamber to ensure that the temperature returns to a safe level, thereby preventing the motor from exploding.

[0038] It should be noted that the internal temperature of the high and low temperature chamber 2 can be changed using a refrigeration unit or a heating unit.

[0039] Furthermore, the heat exchange assembly includes an air inlet pipe 7 and an air outlet pipe 8 installed on the side wall of the high and low temperature chamber 2; both the air outlet pipe 8 and the air inlet pipe 7 are connected to the high and low temperature chamber 2; and both the air inlet pipe 7 and the air outlet pipe 8 are equipped with a fixing plate 9.

[0040] Furthermore, the heat exchange assembly also includes a fixed frame 10 mounted on the fixed plate 9; an intake fan 11 and an exhaust fan 12 are rotatably connected inside the fixed frame 10, and both the intake fan 11 and the exhaust fan 12 are signal connected to the control panel 6; both the fixed frame 10 and the fixed plate 9 are provided with a first threaded hole 13; a bolt 14 is threadedly connected inside the first threaded hole 13.

[0041] Using the above scheme: During use, a signal is sent through the control panel 6 to start the intake fan 11 and the exhaust fan 12. When the intake fan 11 rotates, it will draw in outside air and send it into the high and low temperature chamber 2 through the intake pipe 7. At the same time, the exhaust fan 12 will also rotate, expelling the air in the high and low temperature chamber 2 to the outside through the exhaust pipe 8. In this way, the air in the high and low temperature chamber 2 is constantly replaced by fresh outside air, thereby realizing gas circulation and achieving the effect of cooling or heating.

[0042] It should be noted that when the intake fan 11 and the exhaust fan 12 need to be installed or removed, the bolt 14 needs to be removed from the first threaded hole 13, and then the fixing frame 10 needs to be removed from the fixing plate 9 to complete the installation or removal.

[0043] Furthermore, the clamping member includes a heat insulation plate 15 installed on the inner wall of the high and low temperature chamber 2, and a first rotating shaft 16 is rotatably connected to the heat insulation plate 15; a drive disk 17 is fixedly connected to one end of the first rotating shaft 16, and a plurality of slide rails 18 are installed on the heat insulation plate 15, the slide rails 18 being evenly distributed around the drive disk 17; a first slider 19 is slidably connected to the slide rails 18.

[0044] Furthermore, a first connecting plate 20 is rotatably connected between the first slider 19 and the driving disk 17, and a clamping plate 21 is installed on the first slider 19; a first motor 22 is installed on the lower side of the heat insulation plate 15, and one end of the first rotating shaft 16 is fixedly connected to the output end of the first motor 22.

[0045] Furthermore, a first support frame 23 is installed on the top of the high and low temperature chamber 2; an electric push rod 24 is installed on the top of the first support frame 23, and a clamping frame 25 is installed at the output end of the electric push rod 24; an electromagnet 26 is installed on the inner wall of the clamping frame 25, and a limiting piece 27 that can fit with the circular hole 3 is installed at the output end of the electric push rod 24.

[0046] Using the above scheme: In use, the operator installs the motor into the clamping frame 25, then the electromagnet 26 is energized to fix the motor on the clamping frame 25. Next, the electric push rod 24 pushes the clamping frame 25 into the high and low temperature chamber 2 until the motor reaches the predetermined position. At this time, the output end of the first motor 22 starts to rotate, driving the first rotating shaft 16 and the drive disk 17 to rotate. The rotation of the drive disk 17 pulls the first slider 19 on the slide rail 18 in the preset direction through the first connecting plate 20. The first slider 19 then drives the clamping plate 21 to move synchronously. After the clamping plate 21 moves to the preset position, the clamping plate 21 will contact the motor and clamp the motor.

[0047] It should be noted that: First, the area below the heat insulation plate 15 is at normal temperature, therefore, high and low temperature testing will not affect the normal operation of the first motor 22. Second, after the motor moves to the preset position, the limiting piece 27 will fit onto the circular hole 3, thereby making the high and low temperature chamber 2 a sealed space.

[0048] The working principle of this utility model:

[0049] During the high and low temperature test of the motor, the operator installs the motor into the clamping frame 25, then energizes the electromagnet 26 to fix the motor onto the clamping frame 25. Next, the electric push rod 24 pushes the clamping frame 25 into the high and low temperature chamber 2 until the motor reaches the predetermined position. At this time, the output end of the first motor 22 begins to rotate, driving the first rotating shaft 16 and the drive disk 17 to rotate. The rotation of the drive disk 17 pulls the first slider 19 on the slide rail 18 in a preset direction via the first connecting plate 20. The first slider 19 then drives the clamping plate 21 to move synchronously. After the clamping plate 21 moves to the preset position, it contacts the motor and clamps it. The high and low temperature chamber 2 is used to change the temperature inside the chamber, thereby conducting a temperature test on the motor. During the test, the camera unit 5... The system monitors whether the motor is deformed, and at the same time, the sound detection sensor 4 listens for any abnormal sounds emitted by the motor. These abnormalities may indicate that the motor is at risk of explosion. If the data detected by the camera unit 5 or the sound detection sensor 4 exceeds the safe range, the camera unit 5 or the sound detection sensor 4 will send a signal to the control panel 6. After receiving the signal, the control panel 6 will start the intake fan 11 and the exhaust fan 12. When the intake fan 11 rotates, it will draw in outside air and send it into the high and low temperature chamber 2 through the intake pipe 7. At the same time, the exhaust fan 12 will also rotate, exhausting the air in the high and low temperature chamber 2 to the outside through the exhaust pipe 8. In this way, the air in the high and low temperature chamber 2 is constantly replaced by fresh outside air, thereby achieving gas circulation and thus achieving the effect of cooling or heating.
