Detailed Embodiment

[0020] Next, the technical solutions in this embodiment will be clearly and completely described in conjunction with the accompanying drawings in this embodiment. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figure 1 shown, a tube body inclined plane detection device includes a bottom plate 1 and a cover head 2 located above the bottom plate 1. A die rod 11 is installed at the upper end of the bottom plate 1. The die rod 11 is a cylindrical structure and extends vertically upward along the upper end of the bottom plate 1. The outer wall of the die rod 11 can be sleeved into the tube body 4. Combining Figure 4 , the tube body 4 is a thin-walled cylindrical pipe fitting. The lower end face of the tube body 4 is a plane, and an inclined surface portion 41 is provided at the upper end of the tube body 4. The top surface of the inclined surface portion 41 is an inclined surface. Figure 1 Among them, the left end of the inclined surface portion 41 is the low point of the inclined surface, and the right end is the high point of the inclined surface. A sealing ring 111 is installed on the outer wall of the upper part of the die rod 11. A groove is provided on the outer wall of the die rod 11 for the sealing ring 111 to be snapped into. A part of the sealing ring 111 extends out of the outer wall of the die rod 11, so that when the tube body 4 is sleeved onto the die rod 11, the sealing ring 111 abuts against the inner wall of the tube body 4 to form a seal.

[0022] As Figure 2 shown, the cover head 2 is located above the die rod 11. Combining Figure 3 , the cover head 2 is a cylindrical structure. The cover head 2 is formed by splicing a cover block one 21 and a cover block two 22 located on both sides. The cover block one 21 and the cover block two 22 are semi-circular plates with the same shape. As Figure 1 shown, columns 12 are installed on both sides of the bottom plate 1. A cylinder 121 is installed at the upper end of the column 12. The output ends of the two cylinders 121 are respectively connected to the cover block one 21 and the cover block two 22. The cover block one 21 and the cover block two 22 can move away from each other radially under the drive of the two cylinders 121 to achieve an open state, so as to facilitate the tube body 4 to pass through the cover block one 21 and the cover block two 22 and be sleeved onto the die rod 11, making the height of the entire device lower and improving production safety.

[0023] As Figure 2 shown, a counterbore 23 is provided at the bottom of the cover head 2. The upper bottom surface of the counterbore 23 is an inclined surface with the left bottom and the right high. The inclined surface portion 41 is inserted into the bottom of the cover head 2. The die rod 11 is inserted into the tube body 4 and extends to the upper part of the tube body 4. The top of the die rod 11 is an inclined surface with the same inclined orientation as the inclined surface portion 41.

[0024] As Figure 2As shown in the figure, a slider 6 is slidably connected to the outer wall of the die rod 11. The slider 6 can move up and down along the outer wall of the die rod 11. A spring 7 abuts against the bottom of the slider 6, and the bottom of the spring 7 abuts against the upper end face of the bottom plate 1. The upper end of the slider 6 can abut against the bottom surface of the pipe body 4. After the pipe body 4 is inserted into the die rod 11, the upper end of the inclined surface portion 41 abuts against the upper wall of the counterbore 23. During use, the first cover block 21 and the second cover block 22 move away from each other to form an open state. The pipe body 4 is sleeved on the die rod 11, and the pipe body 4 is pressed down to make the slider 6 move downward. The first cover block 21 and the second cover block 22 move closer to each other to form a closed state. The pipe body 4 is released, and the pipe body 4 is inserted into the counterbore 23. The highest point of the inclined surface portion 41 of the pipe body 4 abuts against the upper wall of the counterbore 23.

[0025] As Figure 2 shown in the figure, a cavity 3 is formed by enclosing the pipe body 4, the die rod 11, and the cover head 2. The cavity 3 is located within the counterbore 23. The cover head 2 includes a first cover block 21 and a second cover block 22. A first groove 211 is provided on one side of the first cover block 21 close to the second cover block 22. A second groove 221 is provided on one side of the second cover block 22 close to the first cover block 21. The first groove 211 and the second groove 221 are arranged oppositely. A first sealing gasket 2111 is installed in the first groove 211, and a second sealing gasket 2211 is installed in the second groove 221. The first sealing gasket 2111 and the second sealing gasket 2211 are arranged in a fitting manner. The first sealing gasket 2111 and the second sealing gasket 2211 are located above the cavity 3.

[0026] As Figure 1 、 Figure 2 shown in the figure, the first cover block 21 is provided with a first flow channel 212. The first flow channel 212 is connected to an air flow generating device 5 through a hose 51. The second cover block 22 is provided with a second flow channel 222. The second flow channel 222 penetrates through the upper end of the second cover block 22. The left side of the cavity 3 is communicated with the first flow channel 212, and the right side of the cavity 3 is communicated with the second flow channel 222. The volume of the cavity 3 gradually decreases from the first flow channel 212 to the second flow channel 222. The first flow channel 212 is located on the lower side near the inclined surface portion 41, and the second flow channel 222 is located on the higher side near the inclined surface portion 41.

[0027] As Figure 2 shown in the figure, the first cover block 21 is provided with a third groove 213, and the second cover block 22 is provided with a fourth groove 223. The positions of the third groove 213 and the fourth groove 223 are both lower than the lowest position of the cavity 3. Sealing gaskets three 2131 and four 2231 are respectively installed in the third groove 213 and the fourth groove 223. The sealing gaskets three 2131 and four 2231 are both in contact with the outer wall of the pipe body 4 to achieve sealing and reduce air leakage.

[0028] As Figure 1 、 Figure 2As shown in the figure, when the gas flow generating device 5 starts to release gas, the gas flows along the hose 51 and the first flow path 212 into the cavity 3, and the gas entering the cavity 3 is discharged from the second flow path 222. Since the raised position at the right end of the inclined surface portion 41 abuts against the upper wall of the counterbore 23, due to the different actual manufacturing dimensions of the upper inclined surfaces of the inclined surface portions 41 of different pipe bodies 4, the different inclination angles result in changes in the volume at the connection between the cavity 3 and the second flow path 222, such that the amount of gas flowing out from the cavity 3 to the second flow path 222 is different. According to the difference in this outflow rate, the indication value on the gas flow generating device 5 is different, and the operator can make a judgment based on this indication value. When the upper inclined surface of the inclined surface portion 41 is completely fitted with the upper wall surface of the counterbore 23, the cavity 3 is completely closed, resulting in the gas being unable to flow out from the second flow path 222. Therefore, by means of the indication value of the gas flow generating device 5 and with reference to the indication value of the standard part, it is possible to quickly cause changes in the volume at the connection between the cavity 3 and the second flow path 222, that is, to judge whether the inclination degree of the upper inclined surface of the inclined surface portion 41 meets the production requirements.

All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention.
