Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile part detection, in particular to an automobile part quality detection tool. BACKGROUND

[0002] With the rapid development of modern industry, the sharp increase in vehicles and the discharge of waste, air pollution problems are becoming more and more serious, which also seriously pollutes the environment on which human beings depend. In view of this problem, most of the exhaust pipes of the current automobile are provided with automobile exhaust purifiers.

[0003] Moreover, since the exhaust pipe is mostly located at the bottom of the vehicle, at the position of contacting the ground, in the process of long-term use, it is easy to be affected by road conditions, moisture, chemicals and high temperature, thereby accelerating the rusting process. Secondly, in the process of vehicle use, the exhaust pipe is often knocked due to road conditions, etc., resulting in the phenomenon of concave or rupture of the exhaust pipe.

[0004] Therefore, in order to prevent rust from affecting the accuracy of ultrasonic detection when detecting cracks in the exhaust pipe, the rust on the exhaust pipe is usually polished first, and then the cracks on the exhaust pipe are detected by the ultrasonic detector. However, when there are dents on the exhaust pipe, metal particles are generated during the polishing process, which are easy to adhere to the dents under the action of surface tension or electrostatic effect of the metal particles. This not only is not convenient to clean, but also the metal particles adhered in the dents will affect the detection accuracy, resulting in reduced detection accuracy. SUMMARY

During the rotation of the pretreatment mechanism, air is delivered to an adapter box arranged above the pretreatment mechanism. The adapter box is communicated with a piston cylinder. A hammering mechanism is arranged in the piston cylinder. The compressed air in the adapter box is used to push the hammering mechanism to knock the exhaust pipe, so that the impurities in the exhaust pipe dents fall off. The hammering mechanism drives the rubber liner arranged inside the shell to approach the exhaust pipe, so as to reduce the distance between the rubber liner and the exhaust pipe.

[0007] As a further improvement of the technical solution, the pretreatment mechanism comprises a spiral disc and a drive system, wherein the drive system comprises a gear and a drive motor, the drive motor is fixed at the bottom of the shell, the output shaft of the drive motor is coaxially connected with the gear, the gear is engaged with the spiral disc, and a plurality of arc-shaped scraping blades are arranged in the spiral disc.

[0008] As a further improvement of the technical solution, a limiting ring is fixedly connected to the upper end of the spiral disc, the limiting ring is embedded in the shell, and the limiting ring is in sliding connection with the shell.

[0009] As a further improvement of the technical solution, a plurality of vanes are arranged on the outer ring of the spiral disc, the vanes are opposite to the arc-shaped scraping blades arranged on the inner side of the spiral disc, a cavity is formed between the spiral disc and the shell, the vanes are located in the cavity, and the cavity is in communication with external air.

[0010] As a further improvement of the technical solution, the cavity is connected with an adapter box through an air pipe, the adapter box is fixedly connected with a piston cylinder, a one-way valve is arranged in the air pipe, and a pressure relief valve is arranged at the end of the piston cylinder.

[0011] As a further improvement of the technical solution, a tension spring is arranged in the piston cylinder, one end of the tension spring is fixedly connected with the inner wall of the piston cylinder, the other end is fixedly connected with a piston plate, the piston plate is in sliding connection with the piston cylinder, a compression spring arranged on the opposite side of the tension spring is fixedly connected with the piston plate, and the compression spring is used to push the hammering mechanism to knock the exhaust pipe.

[0012] As a further improvement of the technical solution, the hammering mechanism comprises an impact head and a plurality of balls arranged in the impact head, the end of the impact head is spherical, the other end is fixedly connected with a limiting plate in sliding connection with the piston cylinder, the limiting plate is fixedly connected with the compression spring, a circular hole is arranged on the rubber inner container in the horizontal direction of the impact head, and the diameter of the circular hole is the same as that of the impact head.

[0013] As a further improvement of the technical solution, a plurality of balls are arranged between two side baffles in the impact head, the baffles are fixedly connected with return springs, and the return springs are fixedly connected with the inner wall of the impact head.

[0014] As a further improvement of the technical solution, a Y-shaped pipe is arranged at the bottom of the piston cylinder away from the adapter box, the Y-shaped pipe is in communication with the piston cylinder, the other end of the Y-shaped pipe is in communication with an air inlet hole arranged on the rubber inner container, the Y-shaped pipe is fixedly connected with the shell at the communication positions of the two ends of the Y-shaped pipe, and an exhaust hole arranged on the shell is in communication with the Y-shaped pipe.

[0015] As a further improvement to this technical solution, a pressing wheel is provided on the Y-shaped tube near the connection between the Y-shaped tube and the piston cylinder. The pressing wheel is rotatably connected to the Y-shaped tube, and a pressing protrusion and a protruding plate are fixedly connected to the pressing wheel. The pressing protrusion and the protruding plate are at a right angle. The mass of the pressing protrusion is greater than that of the protruding plate. The pressing protrusion is located outside the Y-shaped tube, and the protruding plate is located inside the Y-shaped tube.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. In this automotive parts quality inspection fixture, compressed gas is used to push a limiting plate to move, causing multiple balls to approach the limiting plate. Under the action of inertia, after the impact head collides with the exhaust pipe, the multiple balls move away from the limiting plate and impact the inside of the impact head, thereby achieving repeated knocking on the exhaust pipe, improving the effect of impurity removal and the accuracy of crack detection.

[0018] 2. In this automotive parts quality inspection fixture, after the impact head passes through the rubber inner liner, the limiting plate abuts against the rubber inner liner to move the rubber inner liner closer to the exhaust pipe, reducing the distance between the rubber inner liner and the exhaust pipe, increasing the airflow speed, and improving the suction effect on fallen impurities.

[0019] 3. In this automotive parts quality inspection fixture, under the action of the airflow generated by the spiral disc, the airflow attracts the exhaust port. The gas is discharged from the exhaust port through the Y-shaped tube. The released gas plays a role in suppressing the impurities splashed during the spiral disc cleaning process. On the other hand, since the other end of the Y-shaped tube is connected to the air intake port, the gas in the Y-shaped tube, together with the airflow generated by the spiral disc, attracts the air intake port, thereby removing the impurities attached to the exhaust pipe.

[0020] 4. In this automotive parts quality inspection fixture, the rotating extrusion protrusion pushes the rubber inner liner outward. The pushed-out rubber inner liner moves closer to the exhaust pipe, reducing the distance between them. This reduces the cross-sectional area of ​​the rubber inner liner, thus increasing the airflow velocity at that location. This improves the suction effect on impurities and ensures the accuracy of the test results. Attached Figure Description

[0040] The technical solutions in the present application will be described clearly and completely below in combination with the drawings in the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. ​​

[0041] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 indicated, a kind of automobile parts quality detection tool is provided, including support plate 100 and the multiple supports 101 of fixed support plate 100, fixed device 120 is provided on the support 101 of symmetry two sides, and the hydraulic jack 110 of symmetry two sides is provided on the support 101, hydraulic jack 110 is used to control the lifting of the shell 130 of fixed end, multiple ultrasonic detectors 102 are provided outside shell 130, pretreatment mechanism 200 is provided at the bottom inside shell 130, pretreatment mechanism 200 is used to carry out rust removal treatment to rusty exhaust pipe, and pretreatment mechanism 200 sends air to the adapter box 150 being provided above pretreatment mechanism 200 during rotation, adapter box 150 is communicated with piston cylinder 151, hammer mechanism 300 is provided in piston cylinder 151, hammer mechanism 300 is knocked to exhaust pipe using the air compressed in adapter box 150, so that the impurities in the pit of exhaust pipe fall off, and cooperate hammer mechanism 300 to drive the rubber liner 160 being provided in the inside of shell 130 to be close to exhaust pipe, to reduce the distance between rubber liner 160 and exhaust pipe, so as to use the suction force generated by pretreatment mechanism 200 to attract the impurities that fall off, to limit the impurities to drift outward, improve the accuracy of ultrasonic detector 102 detection.

[0042] From this, when pretreating exhaust pipe, the vertical part of exhaust pipe needs to be sequentially passed through support 101, shell 130 and pretreatment mechanism 200, secondly, exhaust pipe is fixed by fixed device 120 on support 101, to prevent the phenomenon of shaking in the process of rust removal, then, under the control of hydraulic jack 110, pretreatment mechanism 200 first removes rust to exhaust pipe, and the process is from top to bottom. Therefore, after pretreatment mechanism 200 processes a section of exhaust pipe, hydraulic jack 110 pushes shell 130 to move downward by a corresponding distance, cooperates multiple ultrasonic detectors 102 to detect exhaust pipe after processing, until the entire exhaust pipe is detected.

[0043] In order to more easily understand the structure of fixed device 120, in combination with Figure 2 indicated, the structure of fixed device 120 is disclosed as follows: fixed device 120 includes clamping end, lead screw and knob, wherein, clamping end rotationally connects the end of lead screw, the other end of lead screw coaxially connects knob, and the auxiliary block threadedly connected with lead screw is fixedly connected with support 101. Specifically in use, rotate knob to drive lead screw to rotate, so that clamping end approaches exhaust pipe, until both sides of clamping end firmly fix and clamp exhaust pipe, stop rotating, and the process is prior art, which can be understood by those skilled in the art, and here is not described in detail.

[0044] Further, on the basis of the above structure, the structure of the pretreatment mechanism 200 is disclosed in combination with Figure 3 and Figure 4 as shown, the pretreatment mechanism 200 includes a spiral disc 210 and a drive system, wherein the drive system is composed of a gear 220 and a drive motor 230, the drive motor 230 is fixed on the bottom of the shell 130, and the output shaft of the drive motor 230 is coaxially connected with the gear 220, the gear 220 is engaged with the spiral disc 210, and a plurality of arc-shaped scrapers are arranged in the spiral disc 210. In this way, after the exhaust pipe is fixed, the gear 220 is driven to rotate by starting the drive motor 230, and the spiral disc 210 is driven to rotate by the gear 220. At this time, the plurality of arc-shaped scrapers inside the spiral disc 210 are used to clean the impurities attached to the exhaust pipe, so as to prevent the impurities from affecting the accuracy of the crack detection of the exhaust pipe.

[0045] And considering that the spiral disc 210 will slide downward under the action of gravity when it stops rotating, a limiting ring 212 is fixedly connected to the upper end of the spiral disc 210, the limiting ring 212 is embedded in the shell 130, and the limiting ring 212 is in sliding connection with the shell 130. In this way, when the spiral disc 210 rotates, the limiting ring 212 limits the downward movement of the spiral disc 210, so as to maintain the stable operation of the spiral disc 210.

[0046] Secondly, on the basis of Figure 4 and in combination with Figure 5 as shown, a plurality of blades 211 are arranged on the outer ring of the spiral disc 210, the blades 211 are opposite to the arc-shaped scrapers arranged on the inner side of the spiral disc 210, a cavity 131 is formed between the spiral disc 210 and the shell 130, the blades 211 are located in the cavity 131, and the cavity 131 is communicated with the external air. Therefore, in order to avoid the upward movement of the air flow generated by the rotation of the arc-shaped scrapers when the arc-shaped scrapers clean the impurities on the exhaust pipe, the blades 211 and the arc-shaped scrapers are arranged in opposite directions, that is, the air flow generated by the rotation of the arc-shaped scrapers flows from top to bottom, and vice versa, the air flow generated by the rotation of the blades 211 flows from bottom to top. Then, when rust removal is performed, the air flow generated by the rotation of the arc-shaped scrapers can avoid the outward spatter of impurities during the cleaning process, and has an inhibitory effect on the impurities.

[0047] Moreover, the air flow generated by the rotation of the arc-shaped scrapers has the following effect: when there are pits on the exhaust pipe, the cleaned impurities are easy to accumulate in the pits, which will affect the accuracy of crack detection. Therefore, the air flow flows from top to bottom, so that the impurities attached to the pits are detached and discharged to the outside along with the air flow through the spiral disc 210. At this time, in combination with Figure 2As shown, in order to prevent the air carrying impurities directly discharged to the outside, causing pollution to the surrounding environment, for this, by setting a corrugated tube at the bottom of the shell 130, the corrugated tube is communicated with the conical hopper (referring to Figure 3 As shown, the conical hopper and the corrugated tube are communicated, the conical hopper is fixed at the bottom of the shell 130) to guide the discharged impurities, the impurities are discharged to the external filtering device (it is prior art, not described here) through the corrugated tube, so that the air is discharged after being purified.

[0048] Returning to Figure 4 and Figure 5 As shown, in another aspect, the cavity 131 is communicated with the adapter box 150 through the air pipe, the adapter box 150 is fixedly connected with the piston cylinder 151, the air pipe is provided with a one-way valve, and the end of the piston cylinder 151 is provided with a pressure relief valve. The gas is transported to the adapter box 150 through the air pipe for storage, that is, the pressure relief valve is closed at this time, the one-way valve is opened (the gas can only flow from the air pipe into the adapter box 150), the gas pressure in the adapter box 150 gradually increases, and after the gas breaks through the pressure relief valve, the gas is sprayed from the adapter box 150 to the piston cylinder 151. When the gas is sprayed from the adapter box 150, the pressure relief valve is closed, and at this time, the adapter box 150 is in the gas storage stage, so as to form intermittent injection.

[0049] In addition, the piston cylinder 151 is provided with a tension spring 152, the tension spring 152 is fixedly connected with the inner wall of the piston cylinder 151, the other end is fixedly connected with the piston plate 153, the piston plate 153 is slidably connected with the piston cylinder 151, the compression spring 154 provided on the opposite side of the tension spring 152 is fixedly connected with the piston plate 153, and the compression spring 154 is used to push the hammer mechanism 300 to knock the exhaust pipe. In this way, after the gas in the adapter box 150 is released, the piston plate 153 is pushed to move towards the exhaust pipe, in the process, as the displacement of the piston plate 153 increases, the tension spring 152 is gradually lengthened, at the same time, the hammer mechanism 300 is pushed outward by the compression spring 154, so as to knock the exhaust pipe. Wherein, the state of the rubber inner liner 160 is changed from Figure 5 to Figure 7 state.

[0050] Therefore, on the basis of the above structure, the following will be combined with Figure 6It is shown that the specific structure of the hammer mechanism 300 is disclosed, the hammer mechanism 300 includes the impact head 310 and a plurality of balls 320 arranged inside the impact head 310, the impact head 310 is spherical at one end, the other end is fixedly connected with the limiting plate 311 which is slidingly connected with the piston cylinder 151, and the limiting plate 311 is fixedly connected with the compression spring 154. In this way, under the pushing of the gas, the compression spring 154 pushes the limiting plate 311 to move, and when the impact head 310 collides with the exhaust pipe, at this time, the impurities fall off from the exhaust pipe. And the plurality of balls 320 are located inside the impact head 310 under normal circumstances, when the compression spring 154 instantaneously pushes the limiting plate 311 to move, the plurality of balls 320 move close to the limiting plate 311, under the action of inertia, after the impact head 310 collides with the exhaust pipe, the plurality of balls 320 move away from the limiting plate 311 (i.e. the balls 320 move towards the exhaust pipe), and the balls 320 impact the inside of the impact head 310, so as to realize repeated knocking of the exhaust pipe and improve the falling-off effect of impurities and the accuracy of crack detection.

[0051] In addition, in order to improve the frequency of knocking the exhaust pipe, the plurality of balls 320 are arranged between the two side baffles 330 inside the impact head 310, the baffles 330 are fixedly connected with the return springs 331, and the return springs 331 are fixedly connected with the inner wall of the impact head 310. When the compression spring 154 pushes the limiting plate 311 at the beginning, the plurality of balls 320 extrude the right side baffle 330, and the right side return spring 331 is compressed. After the impact head 310 collides with the exhaust pipe, under the action of inertia and the elasticity of the right side return spring 331, the right side baffle 330 pushes the ball 320 to pop out in the direction of the exhaust pipe. In this process, the ball 320 impacts the left side baffle 330, so that the left side return spring 331 is compressed, and when the left side return spring 331 moves to the maximum displacement, the left side baffle 330 impacts the inner wall of the impact head 310 through the left side return spring 331, so as to knock the exhaust pipe again, reduce the adhesion of impurities on the exhaust pipe, and improve the accuracy of the detection result.

[0052] Then, the left side baffle 330 reversely pushes the ball 320 to move by using the elastic potential energy of the left side return spring 331, so that the above process is repeated until the ball 320 stops moving. In this way, the impact head 310 knocks the exhaust pipe by using the multiple reciprocating movement of the ball 320, so as to reduce the adhesion of impurities.

[0053] On the basis of Figure 6 and in combination with Figure 7As shown, the reason why the impact head 310 can smoothly pass through the rubber liner 160 is that a circular hole with the same diameter as the impact head 310 is formed in the rubber liner 160 in the horizontal direction of the impact head 310. After the impact head 310 passes through the rubber liner 160, the limiting plate 311 abuts against the rubber liner 160 to drive the rubber liner 160 to move close to the exhaust pipe, thereby reducing the distance between the rubber liner 160 and the exhaust pipe, increasing the speed of airflow flowing through, and improving the suction effect on the detached impurities. The state of the rubber liner 160 during this process is shown in Figure 7 .

[0054] When the impact head 310 contacts the exhaust pipe, the limiting plate 311 is still partially located in the piston cylinder 151 at this time, which facilitates the smooth recovery of the limiting plate 311 in the later stage.

[0055] In addition, in order to better suction the impurities cleaned, in combination with Figure 7 , a Y-shaped pipe 170 is arranged at the bottom of the piston cylinder 151 away from the adapter box 150. The Y-shaped pipe 170 is connected to the piston cylinder 151, and the other end of the Y-shaped pipe 170 is connected to the air inlet hole 161 formed in the rubber liner 160. The Y-shaped pipe 170 is fixedly connected to the shell 130 at the two ends connected to each other. The exhaust hole formed in the shell 130 is connected to the Y-shaped pipe 170. In this way, when the piston plate 153 is pushed by the gas to the position in Figure 7 , that is, the piston plate 153 is located at the connection between the Y-shaped pipe 170 and the piston cylinder 151, at this time, in combination with Figure 4 , under the action of the airflow generated by the spiral disc 210, the airflow attracts the exhaust hole, and the gas is discharged from the exhaust hole through the Y-shaped pipe 170. The released gas plays a role in inhibiting the impurities splashed during the cleaning process of the spiral disc 210. On the other hand, since the other end of the Y-shaped pipe 170 is connected to the air inlet hole 161, the gas in the Y-shaped pipe 170 cooperates with the airflow generated by the spiral disc 210 to attract the air inlet hole 161, thereby sucking away the impurities attached to the exhaust pipe.

[0056] It should be noted that the above right baffle 330 is taken as Figure 6 , the right baffle 330 is the baffle 330 close to the limiting plate 311, and vice versa for the left baffle 330, simply referred to as left and right. Secondly, during the multiple reciprocating movements of the ball 320, in combination with Figure 7 , when the piston plate 153 has not moved to the connection between the Y-shaped pipe 170 and the piston cylinder 151, the impact head 310 has already contacted the exhaust pipe, and the gas is still in the jet state at this time, thereby pushing the piston plate 153 to extrude the compression spring 154, and the piston plate 153 gradually moves in the direction of the exhaust pipe, thereby avoiding the reverse movement of the impact head 310 (i.e., moving away from the exhaust pipe).

[0057] Further, in Figure 7 the basis of and in combination with Figure 8 As shown in the figure, the Y-shaped tube 170 near the connection with the piston cylinder 151 is provided with a pressing wheel 180, which is rotationally connected to the Y-shaped tube 170, and the pressing wheel 180 is fixedly connected with a pressing protrusion 181 and a protruding plate 182, which are at a right angle, the mass of the pressing protrusion 181 is greater than that of the protruding plate 182, the pressing protrusion 181 is located outside the Y-shaped tube 170, and the protruding plate 182 is located inside the Y-shaped tube 170. In this way, when the gas is instantaneously sprayed out of the Y-shaped tube 170, the gas will push the protruding plate 182 to rotate clockwise, and at the same time, the pressing protrusion 181 will rotate to push the rubber inner liner 160 on the side outwards, and the rubber inner liner 160 that is pushed out will move towards the exhaust pipe. The purpose is to reduce the distance between the rubber inner liner 160 and the exhaust pipe, i.e. to reduce the cross-sectional area of the rubber inner liner 160, so that the flow velocity at this position is increased after the cross-sectional area is reduced, thereby improving the suction effect on impurities.

[0058] It should be noted that in the normal state, the pressing protrusion 181 is close to the outer wall of the Y-shaped tube 170, and the pressing protrusion 181 is in a vertical state, and the protruding plate 182 is in a horizontal state.

[0059] Finally, after the gas is sprayed out of the Y-shaped tube 170, since the mass of the pressing protrusion 181 is greater than that of the protruding plate 182, the pressing protrusion 181 is separated from the pressing of the rubber inner liner 160 and returns to the initial state. Moreover, under the elastic action of the tension spring 152, the piston plate 153 is reversely pulled to return to the original position for knocking work again, and at this time, in combination with Figure 2 As shown in the figure, the ultrasonic detector 102 detects the processed exhaust pipe, and the cycle is repeated.

[0060] The above shows and describes the basic principles, main features and advantages of the present application. It should be understood by those skilled in the art that the present application is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only preferred examples of the present application and are not intended to limit the present application.
