Description

Technical Field

[0001] The present application relates to the technical field of automobile pipe fittings detection, and in particular to a detection device for the production of new energy automobile pipe fittings. Background Art

[0002] New energy vehicle pipe fittings are mainly responsible for transporting liquids and air to ensure that each system can operate stably. Pipe fittings require good air tightness, so the air tightness of pipe fittings needs to be tested after production. At present, pipe fittings are usually placed in water, and then gas is introduced into the pipe fittings. If the air tightness of the pipe fittings is not good, bubbles will be generated. However, for small cracks and pores, it takes a long time to pass gas into the hose before they can be detected, and the detection efficiency is low. Summary of the invention

[0003] In order to overcome the disadvantage that it takes a long time to pass gas into a hose to detect tiny cracks and pores, resulting in low detection efficiency, the present invention provides a detection device for the production of new energy vehicle pipe fittings.

[0004] The technical solution is as follows: A detection equipment for the production of new energy vehicle pipe fittings, including a mounting frame and a detection barrel; the mounting frame is connected to the detection barrel; it also includes a power unit, a connecting frame, a fixed disk, a fixing unit, a connecting plate, a connecting rod, a fixed disk and an expansion unit; the mounting frame is connected to a power unit; the power unit is connected to the connecting frame and the connecting plate, and the power unit is used to drive the connecting frame and the connecting plate to move up and down; the connecting frame is fixedly connected to a fixed disk, and an inflation tube is passed through the fixed disk; a fixing unit is connected to the fixed disk; a connecting rod is fixedly connected to the connecting plate, and the connecting rod is slidably connected to the detection barrel; the connecting rod is slidably connected to the fixed disk, and a convex ring is provided on the connecting rod, and the convex ring contacts the lower side of the fixed disk; another fixing unit is connected to the fixed disk, and the two fixing units are used together to fix the pipe fittings; the connecting rod is connected to the expansion unit, and the expansion unit is used to expand the small cracks of the hose.

[0005] Optionally, a camera is provided on the lower side of the connecting frame, and the camera is located directly above the detection barrel.

[0006] Optionally, the fixing unit includes annular airbag 1 and annular airbag 2; annular airbag 1 and annular airbag 2 are fixedly connected to a lower side of the fixing plate and an upper side of the fixing plate 2 respectively; and annular airbag 1 is located inside annular airbag 2.

[0007] Optionally, the surfaces of the annular airbag 1 and the annular airbag 2 are both roughened.

[0008] Optionally, the expansion unit includes an electric push rod, a second connecting rod, a rotating shaft, a support rod, a second power unit and a limit rod; the electric push rod is fixedly connected to the lower part of the connecting rod; the second connecting rod is fixedly connected to the telescopic end of the electric push rod; the second connecting rod is slidingly connected to the first connecting rod; the upper part of the first connecting rod is fixedly connected to the rotating shaft; the rotating shaft is rotatably connected to two support rods through a torsion spring; the second power unit is fixedly connected to the connecting plate, and the second power unit is used to drive the first connecting rod to rotate; a number of limit rods are fixedly connected in the detection barrel; a number of limit grooves are opened on the lower side of the second fixed plate.

[0009] Optionally, the lower portion of the abutment rod is configured to be spherical.

[0010] Optionally, the upper portion of the limiting rod is configured to be conical.

[0011] Optionally, an arc-shaped bar is also included; two arc-shaped bars are respectively fixed to the two spherical parts of the two support rods, the two arc-shaped bars are symmetrically arranged, and each arc-shaped bar is provided with a plurality of convex rings.

[0012] Optionally, a plurality of grooves are formed on the spherical portion of the abutment rod.

[0013] Optionally, an electrode plate is also included; the inner wall of the detection barrel is connected to two electrode plates, and the two electrode plates are symmetrically arranged.

[0014] The beneficial effects of the present invention are as follows: 1. After the hose is immersed in the water in the detection bucket, the two spherical parts of the support rod are pressed against the inner wall of the hose, applying pressure to the inner wall of the hose, so that the hose is stretched, and the small cracks on the inner wall of the hose are temporarily enlarged, thereby facilitating the discharge of gas from the hose and generating bubbles, thereby improving the detection efficiency. At the same time, the spherical part of the support rod applies pressure to the inner wall of the hose, temporarily enlarging the small cracks on the inner wall of the hose, and also facilitating the increase of the amount of gas entering the water, facilitating the generation of a large number of bubbles, and facilitating observation by humans or video instruments, thereby avoiding misdetection caused by small cracks and unclear bubble generation.

[0015] 2. The present invention provides an arc strip on the ball-shaped part of the support rod. When the two ball-shaped parts of the support rod are pressed against the inner wall of the hose, the arc strip moves along with the ball-shaped parts of the support rod and is pressed against the inner wall of the hose. The convex ring on the arc strip will squeeze the inner wall of the hose obliquely upward, so that the upper part of the small cracks in the horizontal and vertical states are pulled upward, thereby preventing the small cracks in the horizontal and vertical states from closing after the hose is expanded, thereby reducing the detection efficiency.

[0016] 3. In order to improve the friction coefficient and efficiency of the push rod against the inner wall of the hose, the present invention uses electrorheological fluid as the test water injected into the test barrel. Before friction, the two electrode plates are energized to generate an electric field in the test barrel. The electrorheological fluid solidifies under the action of the electric field, thereby providing a hard support for the outer wall of the hose, preventing the hose from being squeezed and deformed by the push rod, thereby improving the coefficient and friction efficiency of the push rod against the inner wall of the hose.

[0024] In order to increase the friction force on the hose and prevent the hose from being separated from the annular airbag 1 7 and the annular airbag 2 8, the surfaces of the annular airbag 1 7 and the annular airbag 2 8 are both roughened.

[0027] In order to facilitate the insertion of the limiting rod 34 into the slot on the second fixing plate 12 , the upper portion of the limiting rod 34 is configured to be conical.

[0030] In order to increase the friction between the spherical portion of the push rod 24 and the inner wall of the hose and enhance the friction effect, a plurality of grooves are formed on the spherical portion of the push rod 24.

[0031] Step 1: Control the electric slide rail 3 to drive the electric slider 1 4, the connecting frame 5, the fixed plate 1 6, the annular airbag 1 7, the annular airbag 2 8, the electric slider 2 9, the connecting plate 10, the connecting rod 1 11 and the fixed plate 2 12 to move upward, and the connecting rod 1 11 drives the fixed plate 2 12 to move upward through the convex ring, so that the fixed plate 1 6 and the fixed plate 2 12 are both located above the detection barrel 2; then, water is injected into the detection barrel 2, and the annular airbags 1 7 and the annular airbags 2 8 on the fixed plate 1 6 and the fixed plate 2 12 are externally connected to the air pump, and then, the hose to be tested is manually connected. The hose is sleeved outside the connecting rod 11, and the lower end surface is placed on the fixed disk 2 12, the lower end of the hose is located between the annular airbag 1 7 and the annular airbag 2 8 on the fixed disk 2 12, and the air pump is controlled to inflate the annular airbag 1 7 and the annular airbag 2 8, so that the annular airbag 1 7 and the annular airbag 2 8 expand and clamp the lower end of the hose, and then the upper end of the hose is placed between the annular airbag 1 7 and the annular airbag 2 8 on the fixed disk 1 6, and the air pump is controlled to inflate the annular airbag 1 7 and the annular airbag 2 8, so that the annular airbag 1 7 and the annular airbag 2 8 expand and clamp the upper end of the hose.

[0032] Step 2: Then control the electric slide rail 3 to drive the electric slider 1 4, the connecting frame 5, the fixed plate 1 6, the annular airbag 1 7 and the annular airbag 2 8 to move upward, and the annular airbag 1 7 and the annular airbag 2 8 on the fixed plate 1 6 drive the upper part of the hose to move, so that the hose is straightened, and then control the electric slide rail 3 to drive the electric slider 1 4, the connecting frame 5, the fixed plate 1 6, the annular airbag 1 7, the annular airbag 2 8, the electric slider 2 9, the connecting plate 10, the connecting rod 1 11 and the fixed plate 2 12 to move downward, so that the annular airbag 1 7 and the annular airbag 2 8 on the fixed plate 1 6 and the fixed plate 2 12 drive the hose to move downward and immerse in the water in the detection barrel 2, and connect the inflation tube 601 and the annular airbag 2 8 through the hose. An external air pump is connected, and the external air pump is controlled to inject gas into the hose through the inflation tube 601, and then the camera on the lower side of the connecting frame 5 is used to observe whether there are bubbles in the detection barrel 2. If so, it means that the hose is not air-tight and there are cracks. If not, the hose is qualified for air-tightness. After the inspection, the electric slide rail 3 is controlled to drive the electric slider 1 4, the connecting frame 5, the fixed plate 1 6, the annular airbag 1 7, the annular airbag 2 8, the electric slider 2 9, the connecting plate 10, the connecting rod 1 11 and the fixed plate 2 12 to move upward, so that the annular airbag 1 7 and the annular airbag 2 8 on the fixed plate 1 6 and the fixed plate 2 12 drive the hose to move up to the top of the detection barrel 2, and finally the hose can be removed.

[0033] In order to improve the detection efficiency, after the hose is immersed in the water in the detection barrel 2, the electric push rod 21 is controlled to drive the connecting rod 22 to move upward, and the connecting rod 22 moves up and contacts the two push rods 24, and then drives and forces the two push rods 24 to rotate opposite to each other around the rotating shaft 23, so that the spherical parts of the two push rods 24 are against the inner wall of the hose, applying pressure to the inner wall of the hose, so that the hose is stretched, and the small cracks on the inner wall of the hose are temporarily enlarged, so as to facilitate the discharge of gas from the hose and generate bubbles, thereby improving the detection efficiency. At the same time, the spherical part of the push rod 24 applies pressure to the inner wall of the hose to temporarily enlarge the small cracks on the inner wall of the hose, which is also convenient for increasing the amount of gas entering the water, facilitating the generation of a large number of bubbles, and facilitating observation by manual or video equipment, thereby avoiding small cracks and unclear bubble generation that may cause false detection.

[0034] Considering that the part of the hose close to the push rod 24 can be fully stretched, while the part between the two push rods 24 cannot be effectively stretched, therefore, during the detection process, the control motor 31 drives the gear 32, the gear ring 33, the connecting rod 11, the connecting rod 22, the rotating shaft 23 and the push rod 24 to rotate, so that the push rod 24 rotates relative to the inner wall of the hose, and the part of the hose that is stretched by the push rod 24 changes, so that all parts of the hose can be fully stretched, and the small cracks at various places on the inner wall of the hose are temporarily enlarged to prevent Missed detection; at the same time, the electric slide rail 3 is controlled to drive the electric slider 1 4 and the electric slider 2 9 to move downward, so that the annular airbag 1 7 and the annular airbag 2 8 on the fixed plate 1 6 and the fixed plate 2 12 drive the hose to move downward and immerse it in the water in the detection barrel 2, and the limit rod 34 is inserted into the limit groove on the lower side of the fixed plate 2 12, so that the fixed plate 2 12 is limited to prevent it from swinging after being located in the water and moving downward under the influence of gravity, stretching the hose, causing small cracks to be compressed after the hose is stretched and affecting the detection.

[0035] After inspecting a certain height of the hose, the electric slide rail 3 is controlled to drive the electric slider 2 9, the connecting plate 10, the connecting rod 1 11, the connecting rod 22, the rotating shaft 23 and the push rod 24 to move downward. At this time, the fixed disk 2 12 is blocked by the limit rod 34, and the fixed disk 2 12 and the hose fixed thereon will not move downward, so that the push rod 24 moves down relative to the inner wall of the hose to an undetected position, and the above actions are repeated to inspect multiple locations on the inner wall of the hose and increase the inspection surface; after the inspection is completed, the electric slide rail 3 is controlled to drive the electric slider 1 4, the connecting frame 5, the fixed disk 1 6, the annular airbag 1 7, the annular airbag 2 8, the electric slider 2 9, the connecting plate 10, the connecting rod 1 11 and the fixed disk 2 12 to move upward, so that the fixed disk 1 6 and the annular airbag 1 7 and the annular airbag 2 8 on the fixed disk 2 12 drive the hose to move up again to the top of the inspection barrel 2.

[0036] The spherical parts of the two abutting rods 24 abut against the inner wall of the hose, applying pressure to the inner wall of the hose, so that after the hose is expanded, the upper and lower parts of the small cracks in the horizontal and vertical state will be close to each other and shrink, resulting in the closure of the small cracks. Figure 7 As shown, at this time, the two supporting rods 24 need to rotate and directly press against the horizontal and vertical cracks. After the horizontal and vertical cracks are expanded, the horizontal and vertical cracks can be detected, which requires the supporting rods 24 to be rotated frequently to achieve detection efficiency; therefore, an arc strip 25 is provided on the spherical part of the supporting rod 24. When the spherical parts of the two supporting rods 24 press against the inner wall of the hose, the arc strip 25 moves with the spherical parts of the supporting rods 24 and presses against the inner wall of the hose together. The convex ring on the arc strip 25 will squeeze the inner wall of the hose obliquely upward, so that the upper part of the small horizontal and vertical cracks is pulled upward, thereby avoiding the closing of the small horizontal and vertical cracks after the hose is expanded, thereby reducing the detection efficiency.

[0037] After testing the air tightness of the hose, if it is found that the air tightness of the hose is normal, the wear resistance of the inner wall of the hose can be tested again: control the spherical part of the push rod 24 to press against the inner wall of the hose, and then control the motor 31 to drive the gear 32, the gear ring 33, the connecting rod 11, the connecting rod 22, the rotating shaft 23 and the push rod 24 to rotate reciprocatingly, so that the push rod 24 rotates relative to the inner wall of the hose, and the inner wall of the hose is rubbed by the push rod 24. After rubbing for a certain period of time, the hose is taken out and the wear condition of the inner wall of the hose is detected by using a camera to detect the wear resistance of the inner wall of the hose.

[0038] Embodiment 2: Based on embodiment 1, Figure 2 and Figure 4 As shown, an electrode plate 41 is also included; the inner wall of the detection barrel 2 is connected to two electrode plates 41, and the two electrode plates 41 are symmetrically arranged.

[0039] The push rod 24 is controlled to rotate relative to the inner wall of the hose, and the inner wall of the hose is rubbed by the push rod 24. When friction detection is performed, the hose will be squeezed and deformed by the push rod 24, resulting in lower friction coefficient and efficiency of the push rod 24 on the inner wall of the hose. In order to increase the friction coefficient and efficiency of the push rod 24 on the inner wall of the hose, electrorheological fluid is used for the detection water injected into the detection barrel 2. Before friction, the two electrode plates 41 are energized to generate an electric field in the detection barrel 2. The electrorheological fluid solidifies under the action of the electric field, thereby providing hard support for the outer wall of the hose to prevent the hose from being squeezed and deformed by the push rod 24, thereby increasing the coefficient and friction efficiency of the push rod 24 on the inner wall of the hose. After friction, the electrode plates 41 are no longer energized, and the electrorheological fluid turns back into liquid again.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
