[0008] As a further solution of the utility model: The fixing mechanism includes a placement box fixedly connected inside the built-in box. A cross-shaped platform is fixedly connected to the inner bottom side of the placement box. A pair of mirror-image designed guiding pieces are respectively fixedly connected to the four sides of the top of the cross-shaped platform. A slider that can move in the middle bamboo is slidably connected to the inner sides of a pair of guiding pieces on the same side. A driving block is fixedly connected to the top of the slider.

[0009] As a further solution of the utility model: The guiding piece is in a "T" shape, and the shape of the slider is adapted to the inner sides of a pair of guiding pieces on the same side.

[0010] As a further solution of the utility model: A rotatable rotating rod is rotatably connected to the middle position of the top of the cross-shaped platform.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] This is used for the multi-functional temperature durability test tooling of new energy vehicle parts. By inputting the test temperature of vehicle parts into the controller, the controller starts the electric heater or refrigeration device according to the input temperature. At the same time, the temperature controller continuously feeds back the internal temperature of the built-in box to the controller until the internal temperature of the built-in box is the same as the set temperature. When the electric heater is in use, the output end of the electric heater heats the surface of the built-in box, and the heated temperature is then transferred to the parts inside the built-in box, so as to achieve the effect of high-temperature durability test for the parts. When the refrigeration device is started, the output end of the refrigeration device cools the inside of the built-in box, so as to achieve the effect of low-temperature durability test for the parts. Since the above device can test the durability of parts at high temperature or low temperature respectively, the test efficiency is improved.

[0016] In addition, this is used for the multi-functional temperature durability test tooling of new energy vehicle parts. The rotating rod that rotates counterclockwise drives the turntable to rotate in the same direction. The turntable and the guide groove rotate in the same direction, driving the connecting rod to slide along the inside of the guide groove, so that the position of the guide groove gradually approaching the center of the circle contacts the connecting rod. Through the connecting rod and the connecting rod, the sliding table is driven to move inward, and the clamping component is driven by the driving rod to clamp and fix the parts. Similarly, when the rotating rod is rotated clockwise, the connecting rod can be driven by the turntable to move outward, and then the four-side driving rods and the clamping component are separated, so as to facilitate the removal of the parts after the test. Thus, the effect of stable clamping and separation of parts during the test is achieved. Description of the Drawings

Specific implementation mode

[0023] As Figure 1 , 2 shown, a multi-functional temperature durability test tooling for new energy vehicle parts includes an isolation box 10. An internal built-in box 11 is fixedly connected inside the isolation box 10, and an isolation layer 12 is formed between the built-in box 11 and the isolation box 10; Electric heaters 13 are fixedly connected to the left and right sides inside the isolation layer 12; A sealed box cover 20 is arranged on the top of the isolation box 10, and an output end 21 of a refrigeration device is fixedly connected to the bottom of the sealed box cover 20; A fixing mechanism 30 is arranged inside the built-in box 11.

[0024] Preferably, a controller 23 is installed on the front of the isolation box 10, and a temperature detector 22 is installed at the rear side inside the built-in box 11; The controller 23 is electrically connected to the temperature detector 22, the electric heater 13 and the refrigeration device respectively (the refrigeration device here is prior art and will not be described in detail). Before the test, the vehicle parts are fixed and placed inside the built-in box 11 through the fixing mechanism 30, which can prevent the vehicle parts from moving or deforming during the temperature durability test and affecting the test effect. During the test, by inputting the test temperature of the vehicle parts into the controller 23, the controller 23 starts the electric heater 13 or the refrigeration device according to the input temperature. At the same time, the temperature detector 22 real-time feeds back the internal temperature of the built-in box 11 to the controller 23 until the internal temperature of the built-in box 11 is consistent with the set temperature. When the electric heater 13 is in use, the output end of the electric heater 13 heats the surface of the built-in box 11, and the heated temperature is then transmitted to the parts inside the built-in box 11, so as to achieve the effect of high-temperature durability test of the parts. When the refrigeration device is started, the output end 21 of the refrigeration device cools the inside of the built-in box 11, so as to achieve the effect of low-temperature durability test of the parts. Since the above device can test the durability of the parts at high temperature or low temperature respectively, the effect of multi-functionality is achieved.

[0025] Preferably, the isolation box 10 is made of heat-insulating material to prevent the rapid leakage of temperature of the components to the outside during the temperature endurance test, thereby affecting the test of the components.

[0026] Reference Figure 3 , 4 , 5, the fixing mechanism 30 includes a placement box 301 fixedly connected inside the built-in box 11. A cross table 302 is fixedly connected to the inner bottom side of the placement box 301. A pair of mirror-image designed guide pieces 303 are fixedly connected to the four sides of the top of the cross table 302. A movable slider 304 is slidably connected to the inner sides of a pair of the guide pieces 303 on the same side. A driving block 305 is fixedly connected to the top of the slider 304. Through grooves 306 are respectively formed in the front, rear, left, and right sides of the top of the placement box 301. The driving block 305 penetrates through the corresponding through grooves 306, and the driving block 305 is slidably connected to the corresponding through grooves 306. A clamping assembly 40 is installed inside the driving block 305.

[0027] Preferably, the guide piece 303 is in a "T" shape, and the slider 304 is adapted to the inner shapes of a pair of the guide pieces 303 on the same side, so as to achieve the effect of guiding the movement of the slider 304.

[0028] Specifically, a rotatable rotating rod 307 is rotatably connected to the middle position of the top of the cross table 302. A turntable 308 is fixedly connected to the top of the rotating rod 307. A group of guide grooves 309 are formed in the top of the turntable 308. A connecting rod 310 is slidably connected to the inside of the guide groove 309. The bottom parts of a group of the connecting rods 310 are respectively fixedly connected with connecting strips 311. A group of the connecting strips 311 are fixedly connected to the inner sides of the corresponding sliders 304.

[0029] Preferably, the guide groove 309 is designed to gradually approach the center position in the clockwise direction. During use, the counterclockwise rotating rotating rod 307 drives the turntable 308 to rotate in the same direction. The turntable 308 and the guide groove 309 rotate in the same direction, driving the connecting rod 310 to slide along the inside of the guide groove 309, so that the position where the guide groove 309 gradually approaches the center contacts the connecting rod 310. The slider 304 is driven to move inward through the connecting rod 310 and the connecting strip 311, and the clamping assembly 40 is driven by the driving block 305 to clamp and fix the components. Similarly, rotating the rotating rod 307 clockwise can drive the connecting rod 310 to move outward through the turntable 308, so that the driving blocks 305 and the clamping assembly 40 on the four sides are separated, facilitating the removal of the components after the test.

[0030] Further, an installation block 315 is fixedly connected to the top of the cross table 302. The installation block 315 is located at the rear end of a pair of front guiding pieces 303, with a suitable height and not contacting the connecting bar 311 and the slider 304 during movement, thus not interfering with the movement of the device. A cylinder 312 is fixedly connected to the rear side of the installation block 315, and a toothed plate 313 is fixedly connected to the output end of the cylinder 312; a gear 314 is fixedly connected to the rotating rod 307, and the gear 314 meshes with the toothed plate 313. During use, the cylinder 312 is started by an external power supply. When the output end of the cylinder 312 extends, it drives the toothed plate 313 to move backward, and drives the rotating rod 307 to rotate clockwise through the transmission of the toothed plate 313 and the gear 314. Similarly, when the output end of the cylinder 312 contracts, it can drive the rotating rod 307 to rotate counterclockwise.

[0031] Reference Figure 3 , the clamping assembly 40 includes a clamping frame 401 fixedly connected to the inner side of the driving block 305. At both ends of the inner side of the clamping frame 401, turning slots 402 are respectively opened. Inside the turning slots 402, turning blocks 403 are rotatably connected through movable shafts. A turning piece 404 is fixedly connected to the inner side of the turning block 403. A support spring 405 is fixedly connected to the outer side of the turning piece 404, and the other side of the support spring 405 is fixedly connected to the clamping frame 401.

[0032] During use, since there are many parts of an automobile and their shapes are various, usually, the clamping block can only effectively clamp the parts with a flat surface, and it is difficult to stably clamp and fix the cylindrical or irregular parts. When the clamping assembly 40 is in use, as it moves inward with the driving block 305 and gradually approaches the surface of the part, one of the turning pieces 404 in the clamping assembly 40 will contact the outer surface of the part. When contacting, if the part is in a flat shape, the contact force will make the turning piece 404 fit on the surface of the part. If the part is cylindrical or irregular, the extrusion force during contact will make the turning piece 404 turn inward to form a "V" shape. The design of the V-shaped groove matches the cross-sectional shape of the cylinder, that is, the notch composed of two relatively inclined planes contacts the arc surface of the cylinder, thus providing a stable support point, so as to achieve the clamping effect on the cylindrical parts. At the same time, the turning pieces 404 that turn inward or outward of the two turning pieces 404 can adapt to the surface shape of the irregular parts, so as to achieve the effect of stably clamping and fixing parts of different shapes.

[0033] The working principle of the present utility model is as follows: Before the test, the automotive parts are fixedly placed inside the built-in box 11 through the fixing mechanism 30, which can prevent the automotive parts from moving or deforming during the temperature endurance test and affecting the test results. During the test, by inputting the test temperature of the automotive parts into the controller 23, the controller 23 starts the electric heater 13 or the refrigeration device according to the input temperature. At the same time, the temperature detector 22 continuously feeds back the internal temperature of the built-in box 11 to the controller 23 until the internal temperature of the built-in box 11 is the same as the set temperature. When the electric heater 13 is in use, the output end of the electric heater 13 heats the surface of the built-in box 11, and the heated temperature is then transferred to the parts inside the built-in box 11, so as to achieve the effect of high-temperature durability test of the parts. When the refrigeration device is started, the output end 21 of the refrigeration device cools the inside of the built-in box 11, so as to achieve the effect of low-temperature durability test of the parts. Since the above device can test the durability of the parts at high temperature or low temperature respectively, the effect of multi-functionality is achieved.

[0034] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
