Description

Technical Field

[0001] This utility model relates to the field of high and low temperature test chamber technology, specifically a combined high and low temperature test chamber. Background Technology

[0002] High and low temperature test chambers: suitable for reliability testing of industrial products under high and low temperature conditions. They are used to test the performance indicators of components and materials in electronic and electrical products, automobiles, motorcycles, aerospace, shipbuilding, weaponry, universities, research institutions, and other related products under cyclic high and low temperature conditions.

[0003] In industrial production, many products need to meet certain working environments, such as a certain temperature range, and be able to work continuously for a certain period of time in extreme low or high temperature environments. In order to test whether the products meet the working environment requirements, it is necessary to test the products through high and low temperature test chambers. Traditional high and low temperature test chambers are mostly fixed in their placement during use, which is inconvenient to adjust according to the specifications of the test parts. Furthermore, they can only be fixed in place and cannot be rotated for dynamic testing according to the usage. Therefore, we propose a combined high and low temperature test chamber. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a combined high and low temperature test chamber. The adjustable mounting plate can be used to place test pieces of different specifications, while the rotatable rotating disk can perform dynamic tests on the test pieces. This allows for combination and installation according to different test pieces, thereby improving the practicality of the test chamber and effectively solving the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined high and low temperature test chamber, comprising a chamber body and an electromagnet;

[0006] Box body: A door is hinged to the front side. Air inlet pipes are installed at both the front and rear ends of the left side of the box body. Exhaust slots are evenly distributed on the rear side of the box body. Two corresponding bases are provided at the bottom of the rear side of the box body. The bases are positioned opposite the exhaust slots. A fan is placed inside the bases. A sealing ring is adhered to the front side of the box body. There are two electromagnets, which are respectively installed on the right side of the inside of the box body. A combination unit is provided inside the box body.

[0007] It also includes a touch screen, which is located on the front side of the door. The input terminals of the fan and electromagnet are electrically connected to the output terminal of the touch screen, and the input terminal of the touch screen is electrically connected to the output terminal of an external power supply.

[0008] The two air inlets can deliver cold and hot air into the chamber for testing, respectively. The bonded sealing ring can increase the airtightness between the chamber and the door, while the electromagnet can prevent the door from being opened accidentally.

[0009] Furthermore, the assembly unit includes a linear motor, a frame, casters, a plate holder, and a placement plate. There are two linear motors, each fixed to one side of the bottom surface inside the housing. The top surface of the linear motor's actuator is connected to the rear side of the frame's bottom surface.

The input end of the main motor is electrically connected to the output end of the control panel. Rotating the throttle drives the lead screw to rotate, thereby adjusting the position of the fixed clamp. This can fix the placed test piece. Starting the main motor to drive the rotating disk to rotate allows for dynamic testing of the test piece, thus increasing the practicality of the test chamber.

[0011] Furthermore, the assembly unit also includes a screw, a motor, a locking frame, and a locking groove. There are two motors, which are respectively fixed on the left and right sides of the top surface of the frame. The output shaft of the motor is connected to the inner end of the screw.

Plate frames 24 are evenly fixed to the left and right sides inside frame 22. Placement plates 25 are slidably installed inside the plate frames 24. The input of linear motor 21 is electrically connected to the output of control panel 13. The placement plates 25 inside the plate frames 24 can be adjusted according to the specifications of the workpiece to be inspected. Starting the linear motor 21, in conjunction with the casters 23 in contact with the ground, moves frame 22 to facilitate the placement and retrieval of workpieces. The assembly unit 2 also includes a rotary disk 26, a main motor 27, a fixed clamp 28, a lead screw 29, a throttle 210, and a bracket 211, which is fixed inside frame 22. At the bottom end, a main motor 27 is fixed to the bottom surface of the bracket 211. The output shaft of the main motor 27 is connected to the middle of the bottom surface of the rotating disk 26. A lead screw 29 is rotatably installed in the adjustment groove on the top surface of the rotating disk 26. A handle 210 is installed through the outer end of the lead screw 29 through the rotating disk 26. A fixed clamp 28 is slidably installed in the adjustment groove on the top surface of the rotating disk 26. The screw hole on the surface of the fixed clamp 28 is threadedly connected to the lead screw 29. The input end of the main motor 27 is electrically connected to the output end of the control panel 13. Rotating the handle 210 drives the lead screw 29 to rotate, thereby adjusting the position of the fixed clamp 28. This can fix the placed test piece. Starting the main motor 27 to drive the rotating disk 26 to rotate allows for dynamic testing of the test piece, thereby increasing the practicality of the test chamber. The combined unit 2 also includes a screw 212, a motor 213, a locking frame 214, and a locking groove 215. There are two motors 213, which are fixed on the left and right sides of the top surface of the frame 22 respectively. The output shaft of the motor 213 is connected to the inner end of the screw 212. The screw 212 is threadedly connected to the screw hole on the surface of the locking frame 214. The locking groove 215 is opened on the side of the placement plate 25. The locking frame 214 passes through the through groove on the surface of the frame 22 and is correspondingly engaged with the locking groove 215. The input end of the motor 213 is electrically connected to the output end of the control screen 13. When the motor 213 is started, the screw 212 is rotated, and the locking frame 214 is engaged in the locking groove 215 to fix the position of the placement plate 25, so as to prevent the placement plate 25 from loosening and causing the test piece to fall.

[0026] The system includes a touchscreen 13, located on the front side of the door 3. The input terminals of the fan 7 and electromagnet 9 are electrically connected to the output terminals of the touchscreen 13, which in turn are electrically connected to the output terminal of an external power supply.

An adhesive sealing ring 8 increases the seal between the chamber 1 and the door 3, while the electromagnet 9 prevents accidental opening of the door 3. The system also includes two electric telescopic rods 10, fixed to the rear side of the chamber 1, one on the left and one on the right. The top of the electric telescopic rod 10 is connected to both sides of the baffle 11. The input end of the electric telescopic rod 10 is electrically connected to the output end of the control panel 13. When the electric telescopic rod 10 is started, the baffle 11 is raised. The fan 7 then discharges the hot and cold air inside the box 1 through the exhaust duct 5, thus preventing safety issues when personnel handle the equipment. The system also includes a temperature sensor 12, which is fixed on the left side of the box 1. The output end of the temperature sensor 12 is electrically connected to the input end of the control panel 13. The temperature sensor 12 can monitor the temperature inside the box 1 in real time, making it convenient for personnel to adjust the temperature.

[0027] The working principle of the combined high and low temperature test chamber provided by this utility model is as follows: First, the placement plate 25 is inserted into the plate frame 24. The test piece is placed on the top surface of the placement plate 25. The motor 213 is started, driving the screw 212 to rotate, which causes the locking bracket 214 to engage with the locking groove 215 to fix the position of the placement plate 25, preventing the test piece from falling due to loosening of the placement plate 25. At the same time, the handle 210 can be turned to drive the lead screw 29 to rotate, thereby adjusting the position of the fixing clamp 28, which can fix the placed test piece. Starting the main motor 27 drives the rotating disk 26 to rotate, which can perform dynamic testing on the test piece, thereby increasing the practicality of the test chamber. Then, the chamber door 3 is closed. The adhesive sealing ring 8 can increase the sealing between the box body 1 and the box door 3, while the electromagnet 9 can prevent the box door 3 from being opened accidentally. The two air inlet pipes 4 can deliver cold air and hot air into the box body 1 for testing, respectively. The temperature sensor 12 can monitor the temperature inside the box body 1 in real time, so that personnel can adjust it. After the test is completed, the electric telescopic rod 10 is activated to drive the baffle 11 to rise. With the help of the fan 7, the hot air and cold air inside the box body 1 are discharged through the exhaust channel 5, so as to prevent safety problems when personnel take it out. Finally, the linear motor 21 is activated in conjunction with the moving wheels 23 that are in contact with the ground to drive the frame 22 to move so that personnel can take it out.

[0028] It is worth noting that the touch screen 13 disclosed in the above embodiments can be of model XT07001C1F1-B.
