It maintains and protects the microenvironment inside the car, thus playing an important role in protecting car users, electromechanical devices and accessories. Once the sealing strip is affected by high temperature, it is prone to aging and damage, which may lead to a series of problems such as rain leakage in the car and body corrosion. Therefore, automobile sealing strips need to be subjected to high temperature impact tests. Only when they meet the requirements can they be used outside the factory.

[0003] The patent with patent announcement number CN213422607U involves a detection device for sealing strip processing, including a detection platform, a sealing detection chamber, a sealing strip fixing plate, a sealing strip and a wear control component.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 6 One embodiment of the present invention is: a high temperature impact test detection device for automobile sealing strips, comprising a workbench 1, a support frame 2 is fixed on the top of the workbench 1, a cylinder 3 is fixed on the top of the support frame 2, a connecting plate 5 is fixed on the bottom output end of the cylinder 3, a stamping block 6 is fixed on the bottom of the connecting plate 5, a placing plate 4 is fixed on the top of the workbench 1, a heating plate 20 is fixed on the inner wall of the placing groove at the top of the placing plate 4, an adjusting knob for adjusting the temperature of the heating plate 20 is arranged on the top of the workbench 1, and a pressure regulating knob is arranged on the placing plate 4. There is a positioning assembly for positioning the sealing strip; wherein the positioning assembly includes an extrusion block 7, a triangular block 8, a return spring 9, a slider 10, a connecting rod 11, a positioning plate 12, an L-shaped connecting rod 13, a hinge rod 14, an L-shaped transmission block 22, a connecting block 15, a rotating rod 16, a protective plate 17 and a rotating block 18; the extrusion block 7 is fixed to the bottom of the connecting plate 5, the slider 10 is slidably installed on the top of the placement plate 4, the connecting rod 11 is fixed to the side wall of the slider 10, and the positioning plate 12 is fixed to the end of the connecting rod 11 away from the slider 10. Two groups of positioning plates 12 are provided, and the two groups of positioning plates 12 are symmetrically arranged with the center line of the placing plate 4 in the vertical direction as the symmetry axis. A triangular block 8 is slidably installed at the through hole on the top of the placing plate 4. An L-shaped connecting rod 13 is fixed on the top of the triangular block 8. An end of the L-shaped connecting rod 13 away from the triangular block 8 is hinged to a hinge rod 14. An end of the hinge rod 14 away from the L-shaped connecting rod 13 is hinged to the slider 10. An L-shaped transmission block 22 is fixed on the side of the slider 10 away from the connecting rod 11. A return spring 9 is fixed to the side wall of the triangular block 8. The side of the return spring 9 away from the triangular block 8 is fixed to the inner side of the placement plate 4, and a connecting block 15 is fixed to the side wall of the placement plate 4. A rotating rod 16 is rotatably installed on the connecting block 15, and a protective plate 17 is fixed to the outer wall of the rotating rod 16. There are two groups of protective plates 17, and the two groups of protective plates 17 are symmetrically arranged with the center line of the placement plate 4 in the vertical direction as the symmetry axis. A torsion spring is fixed to the side wall of the connecting block 15, and the side of the torsion spring away from the connecting block 15 is fixed to the side wall of the protective plate 17, and a rotating block 18 is fixed to the outer wall of the rotating rod 16.

[0021] By bringing the two groups of positioning plates 12 closer to each other, the positioning plates 12 can center the sealing strip placed on the heating plate 20 so that the sealing strip is exactly at the bottom of the stamping block 6. When the sealing strip is subjected to an impact test, the force is evenly applied, so that the stamping data results are more accurate.

[0022] By setting up two groups of protective plates 17, when the punching block 6 is punching the sealing strip, the two groups of protective plates 17 can be rotated to cover the front and back sides of the placement plate 4, thereby achieving a protective effect and preventing the sealing strip from being broken due to high temperature and impact during the high temperature impact test. The protective plates 17 can prevent the broken fragments from flying around, thereby protecting the surrounding environment and personnel safety.

[0023] When this embodiment is working: when it is necessary to perform high-temperature stamping operation on the sealing strip, the sealing strip is first placed in the placement groove on the top of the placement plate 4, thereby starting the cylinder 3, so that the output end of the cylinder 3 drives the connecting plate 5 to move downward, and the extrusion block 7 moves downward. When the extrusion block 7 moves downward to the inclined surface of the triangular block 8 inside the placement plate 4 for extrusion, the triangular block 8 will be subjected to extrusion force, so that the reset spring 9 can be compressed, and the triangular block 8 can drive the L-shaped connecting rod 13 to move, so that the L-shaped connecting rod 13 moves toward the slider 10, so that the L-shaped connecting rod 13 squeezes the hinge rod 14, and the hinge rod 14 rotates at the hinge, so that the hinge rod 14 can squeeze the slider 10 away from the protective plate 17, and drive the connecting rod 11 to move, so that the connecting rod 11 can drive the two sets of positioning plates 12 to approach each other, so that the two sets of positioning plates 12 can be moved closer to each other. The positioning plate 12 positions the sealing strip in the placement groove at the top of the placement plate 4, and when the output end of the cylinder 3 continues to drive the connecting plate 5 to move downward, the connecting plate 5 drives the stamping block 6 to move downward, so that the stamping block 6 can impact the sealing strip, and by starting the heating plate 20, the temperature of the heating plate 20 is adjusted, and the impact force on the sealing strip at different temperatures is tested, and when the slider 10 drives the connecting rod 11 to move, the slider 10 can drive the L-shaped transmission block 22 to move, so that the L-shaped transmission block 22 squeezes the rotating block 18, so that the rotating block 18 can rotate, and the rotating block 18 drives the rotating rod 16 to rotate, and the rotating rod 16 drives the protective plate 17 to rotate, so that the protective plate 17 blocks the front and back of the placement plate 4, and when the protective plate 17 rotates, the torsion spring will be deformed.

[0024] When the impact test is over, the cylinder 3 is controlled so that the output end of the cylinder 3 drives the connecting plate 5 to move upward, so that the stamping block 6 can move upward, and the connecting plate 5 drives the extrusion block 7 to move upward. When the extrusion block 7 moves upward, the extrusion block 7 will not squeeze the triangular block 8. Because the reset spring 9 is in a compressed state, the reset spring 9 drives the triangular block 8 to reset, so that the triangular block 8 drives the L-shaped connecting rod 13 away from the slider 10, so that the L-shaped connecting rod 13 pulls the hinge rod 14, so that the hinge rod 14 drives the slider 10 to approach the protective plate 17, and the positioning plate 12 is reset through the connecting rod 11 for the next positioning operation. When the slider 10 approaches the protective plate 17, it can drive the L-shaped transmission block 22 not to squeeze the rotating block 18. Because the torsion spring is in a contracted state, the torsion spring can drive the protective plate 17 to rotate and reset, so that the protective plate 17 does not block the placement plate 4, and the sealing strip can be taken.

[0025] See also Figure 1-Figure 8On the basis of the above embodiment, another embodiment of the present invention also includes an extrusion assembly and a cooling assembly, the extrusion assembly includes a slide bar 1901, a slide plate 1902, a slide groove 1903, an L-shaped support plate 1904, a sleeve 1905, an ejector rod 1906, a connecting spring 1907, a push rod 1908, a push plate 1909, a fixed rod 1910, a movable rod 1912, a moving block 1911, a limit rod 1916, a prompt column 1913, a return spring 1915, a limit rod 1916 and an inclined block 1914, the slide Rod 1901 is fixed to the side wall of positioning plate 12, and a slide plate 1902 is slidably installed on the side wall of placing plate 4. Slide plate 1902 is provided with a slide groove 1903, and slide rod 1901 passes through the slide groove 1903, and the penetration part is fitted. An L-shaped support plate 1904 is fixed to the bottom of slide plate 1902, and a sleeve 1905 is fixed to the top of the L-shaped support plate 1904. An ejector rod 1906 is slidably installed on the inner wall of sleeve 1905. A connecting spring 1907 is fixed to the bottom of ejector rod 1906, and the bottom of connecting spring 1907 is fixed. The inner wall of the sleeve 1905 is fixed, and a push rod 1908 is fixed at the bottom of the ejector rod 1906. The push rod 1908 penetrates the bottom of the L-shaped support plate 1904 and the sleeve 1905, and is slidably connected at the penetration point. A push plate 1909 is fixed at the bottom of the push rod 1908. A fixed rod 1910 penetrates the L-shaped support plate 1904, and is slidably connected at the penetration point. A moving block 1911 is slidably installed on the top of the L-shaped support plate 1904, and a movable rod 1912 is hinged on the moving block 1911, and the movable rod 1912 is away from the moving block 1 One end of 911 is hinged at the top of the fixed rod 1910, and a limiting rod 1916 is fixed to the side wall of the movable block 1911. A prompt column 1913 passes through the L-shaped support plate 1904, and is slidably connected at the penetration point. An inclined block 1914 is fixed to the bottom of the prompt column 1913, and a return spring 1915 is fixed to the top of the inclined block 1914. The top of the return spring 1915 is fixed to the bottom of the L-shaped support plate 1904. A limiting hole is provided on the outer wall of the prompt column 1913, and the inner wall of the limiting hole fits with the outer wall of the limiting rod 1916.

[0026] By setting the ejection rod 1906 to move upward, the sealing strip that is heated and adhered to the heating plate 20 can be lifted up, thereby making it convenient for the staff to take the sealing strip.

[0027] Because the return spring 1915 is in a stretched state, the return spring 1915 can drive the inclined block 1914 and the prompt column 1913 to move upward, so that the prompt column 1913 is moved out from the top of the placement plate 4, thereby serving as a reminder for the staff to prevent the temperature from being too high and the staff from taking the sealing strip and causing harm to the staff.

[0028] The cooling component includes a water tank 211, a water pump 212, a cooling water pipe 213, a controller 214, a spring switch 215, a transmission spring 216 and an inclined block 217. The water tank 211 is fixed on the top of the workbench 1, and the water pump 212 is fixed on the right side of the water tank 211. The output end of the water pump 212 is connected to the water tank 211. The cooling water pipe 213 is fixed on the side of the water pump 212 away from the water tank 211. The end of the cooling water pipe 213 away from the water pump 212 passes through the side wall of the water tank 211, and the cooling water pipe 213 is connected to the water tank 211. The box 211 is connected, and the cooling water pipe 213 is in contact with the outer wall of the heating plate 20. A controller 214 is fixed on the top of the workbench 1, and a spring switch 215 is fixed on the side wall of the controller 214. A ramp block 217 is slidably installed on the top of the workbench 1, and a transmission spring 216 is fixed on the side wall of the ramp block 217. The side of the transmission spring 216 away from the ramp block 217 is fixed to the side wall of the controller 214. The water pump 212 is electrically connected to the controller 214, and the controller 214 is electrically connected to the spring switch 215.

[0029] Cooling water is added to the water tank 211, and the cooling water flows in the cooling water pipe 213, so as to cool down the residual temperature on the heating plate 20 after the processing is completed, so as to prevent the residual temperature on the heating plate 20 from being too high, which will make the temperature of the sealing strip too high, and the staff may be easily burned when taking the sealing strip.

[0030] When the present embodiment is working, when the two groups of positioning plates 12 are close to each other, the slide bar 1901 will move in the inclined groove of the slide groove 1903 of the slide plate 1902, so that the slide bar 1901 will squeeze the inclined groove of the slide groove 1903. Because the slide plate 1902 will be subjected to the squeezing force, the slide plate 1902 will move downward, thereby driving the L-shaped support plate 1904 to move downward, so that the sleeve 1905 and the ejector rod 1906 move downward, and the ejector rod 1906 is removed from the top of the heating plate 20. When the processing is completed, the positioning plate 12 will drive the slide bar 1901 to move in the slide groove 1903. When the slide bar 1901 moves to the inclined groove of the slide groove 1903, the slide bar 1901 will squeeze the slide plate 1902 to move upward, so that The slide plate 1902 drives the L-shaped support plate 1904 to move upward, so that the sleeve 1905 drives the ejector rod 1906 to move away from the top of the heating plate 20, so that the ejector rod 1906 can lift up the sealing strip that is heated and adhered to the heating plate 20, which is convenient for the staff to take the sealing strip. When the temperature of the heating plate 20 is too high, the residual temperature is too high after the processing is completed, which will make the sealing strip tightly adhere to the heating plate 20. When the ejector rod 1906 squeezes the sealing strip upward, the ejector rod 1906 is squeezed due to the tight adhesion, so that the ejector rod 1906 moves downward in the sleeve 1905, compressing the connecting spring 1907, and when the push rod 1908 is in the L-shaped support plate 1904, the push rod 1908 is pressed against the sealing strip. When moving downward, the push plate 1909 will move downward, so that the push plate 1909 drives the fixed rod 1910 to move downward, and the fixed rod 1910 pulls the movable rod 1912, so that the movable rod 1912 rotates at the hinge, so that the movable rod 1912 pulls the movable block 1911 to approach the sleeve 1905, and the limiting rod 1916 moves out of the limiting hole of the prompt column 1913, thereby releasing the limit on the prompt column 1913, and because the return spring 1915 is in a stretched state, it can drive the inclined block 1914 to move upward, so that the return spring 1915 drives the inclined block 1914 and the prompt column 1913 to move upward, so that the prompt column 1913 moves out from the top of the placement plate 4, prompting the staff to prevent The temperature on the heating plate 20 and the sealing strip is too high. If the staff tries to take the sealing strip, it will cause injuries. When the return spring 1915 drives the inclined block 1914 to move upward, the inclined surface of the inclined block 1914 will squeeze the inclined surface of the inclined block 217, and the inclined block 217 will be moved toward the controller 214 by the squeezing force, so that the transmission spring 216 is compressed, thereby causing the inclined block 217 to squeeze the spring switch 215, so that the controller 214 can control the water pump 212 to start, so that the water pump 212 draws the cooling water in the water tank 211, and the cooling water flows into the cooling water pipe 213, and the heating plate 20 is cooled through the cooling water pipe 213, and the sealing strip is indirectly cooled, which makes it convenient for the staff to take the sealing strip.

[0031] When the prompt column 1913 moves upward, the limit rod 1916 will be pressed against the outer wall of the prompt column 1913, so that the connecting spring 1907 is always in a compressed state. When the heating plate 20 does not need to be cooled, the prompt column 1913 can be pushed downward to stretch the return spring 1915. When the prompt column 1913 moves to the limit hole and is aligned with the limit rod 1916, the connecting spring 1907 is in a compressed state, so that the ejection rod 1906 drives the push rod 1908 to move upward, and the push plate 1909 drives the fixed rod 1910 to move upward, so that the fixed rod 1910 squeezes the movable rod 1912, so that the movable rod 1912 912 rotates at the hinge, thereby pushing the moving block 1911 to approach the prompt column 1913, so that the limiting rod 1916 extends into the limiting hole provided on the outer wall of the prompt column 1913, thereby fixing the prompt column 1913 and performing the next prompt operation. When the prompt column 1913 moves downward, the inclined block 1914 does not squeeze the inclined surface block 217, and the transmission spring 216 is in a compressed state, which causes the transmission spring 216 to drive the inclined surface block 217 away from the controller 214, so that the inclined surface block 217 does not squeeze the spring switch 215, so that the spring switch 215 is reset, thereby turning off the water pump 212.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
