Description

Technical Field

[0001] This application relates to the field of three-way catalytic converter testing equipment, and in particular to a three-way catalytic converter testing station. Background Technology

[0002] Currently, a three-way catalytic converter is a device installed in the exhaust pipe of a car to convert harmful gases such as carbon monoxide, hydrocarbons, and nitrogen oxides in the exhaust gas of a car engine into harmless substances. The three-way catalytic converter mainly consists of a cylindrical shell, inside which a honeycomb carrier and catalytic material are arranged.

[0003] Currently, after the three-way catalytic converter is assembled, it needs to be manually inspected. Workers use a rubber mallet to tap the cylinder with appropriate force, and judge whether there is any damage to the internal structure of the three-way catalytic converter by the sound feedback from inside the cylinder. When a fine "crackling" sound is heard and loose objects fall down, it is judged as an abnormal noise, indicating that the catalytic material inside the three-way catalytic converter has peeled off or the honeycomb ceramic carrier has broken.

[0004] The existing technical solutions mentioned above have the following drawbacks: When workers manually inspect the three-way catalytic converter, the tapping of the cylinder is based on their personal work experience, and different workers have different tapping forces. When the tapping force is too great, it is easy to cause artificial damage to the internal structure of the cylinder, which is not conducive to the inspection of the three-way catalytic converter. Utility Model Content

[0005] This application provides a three-way catalytic converter testing station to facilitate the stable force of tapping tests on the three-way catalytic converter.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0007] A three-way catalytic converter testing platform includes a base plate, a buffer mechanism disposed on the base plate, a clamping mechanism disposed on the upper part of the buffer mechanism, a lifting mechanism vertically disposed on the base plate and spaced apart from the buffer mechanism, a sliding mechanism disposed on the top lifting end of the lifting mechanism, and a striking mechanism connected to the sliding end of the sliding mechanism, wherein the striking end of the striking mechanism is located above the clamping mechanism.

[0008] The buffer mechanism includes a vertically arranged column with its lower end fixed to the base plate, a sleeve sleeved on the outside of the column, a buffer spring disposed between the upper end face of the column and the inner wall of the closed end of the sleeve, and a limiting bolt for limiting the range of movement of the sleeve relative to the column.

[0009] By adopting the above technical solution, and by setting up an overall frame consisting of a base plate, a buffer mechanism, a clamping mechanism, a lifting mechanism, a sliding mechanism, and a striking mechanism, and by placing the striking end of the striking mechanism above the clamping mechanism, the three-way catalytic converter cylinder to be tested can be stably clamped and receive a stable striking force from above. The buffer spring and the limiting bolt in the buffer mechanism work together to provide buffer descent space for the cylinder when the striking force is too large, effectively avoiding human-caused damage to the internal structure of the cylinder due to excessive impact force, thus facilitating stable and reliable striking inspection.

[0010] Optionally, the clamping mechanism includes a placement block fixedly disposed on the upper end of the sleeve, a connecting post slidably disposed on the placement block, a compression spring sleeved on the connecting post, a clamping block fixedly disposed on one end of the connecting post, and a screw threadedly connected to the placement block and abutting against the clamping block to adjust its position.

[0011] By adopting the above technical solution, the clamping mechanism adjusts the position of the clamping block through the screw and provides continuous clamping force using the compression spring. It can adapt to cylinders of different sizes and achieve fast and stable clamping, providing a solid benchmark for subsequent impact testing and avoiding the instability of manual hand-held operation.

[0012] Optionally, the top of the placement block is provided with a placement groove for accommodating the three-way catalytic converter cylinder, and the clamping block is machined with an arc-shaped surface on the side facing the placement groove.

[0013] By adopting the above technical solution, the arc-shaped surfaces of the placement groove and the clamping block together form an enclosing structure with a radius greater than 180°, which can better fit the outer wall of the cylinder, increase the contact area, and make the cylinder less likely to shift or rotate during the striking process, thus ensuring the accuracy of the striking position and the reliability of the test results.

[0014] Optionally, the lifting mechanism includes a mounting shell fixedly mounted on the base plate, a lifting rod movably passing through the upper end of the mounting shell, a rotating shaft rotatably mounted inside the mounting shell with its axis horizontal, a gear fixedly sleeved on the rotating shaft and meshing with a tooth groove provided on the outer wall of the lifting rod, and a connecting rod for driving the rotating shaft to rotate.

[0015] By adopting the above technical solution, the lifting rod can be precisely controlled by the meshing transmission of gears and tooth grooves and rotating the connecting rod, thereby flexibly adjusting the height of the sliding mechanism and the striking mechanism to adapt to three-way catalytic converters of different specifications and ensuring that the striking hammer can accurately land at the appropriate position on the cylinder.

[0016] Optionally, the lifting mechanism may further include a positioning component disposed outside the mounting housing to prevent the rotating shaft from rotating in a set direction.

[0017] By adopting the above technical solution, the positioning component can effectively prevent the lifting rod from falling accidentally after it is adjusted to a suitable height, ensuring the high stability of the striking mechanism during operation, avoiding the deviation of striking force or position caused by changes in height, and ensuring the repeatability and accuracy of the detection operation.

[0018] Optionally, the sliding mechanism includes a connecting plate fixedly disposed on the upper end of the lifting rod, a slider slidably disposed on the connecting plate, and positioning bolts for fixing the slider at different positions on the connecting plate.

[0019] By adopting the above technical solution, the slider can slide along the connecting plate and be fixed by the positioning bolts, which allows the operator to flexibly adjust the position of the striking mechanism in the horizontal direction, thereby facilitating the striking inspection of different parts of the cylinder and improving the comprehensiveness and convenience of the inspection.

[0020] Optionally, the striking mechanism includes a mounting plate fixedly mounted on the slider, a striking component vertically slidably mounted on the mounting plate, a driving component rotatably mounted on the mounting plate and abutting against the striking component to drive it to move up and down periodically, and a power component for driving the driving component to operate.

[0021] By adopting the above technical solution, the striking mechanism converts the rotational motion into the periodic linear reciprocating motion of the striking component through the power component and drive component, realizing automatic mechanical striking, replacing manual striking, completely eliminating the problem of uneven striking force caused by differences in personal experience, and ensuring the consistency of striking force for each strike.

[0022] Optionally, the striking assembly includes a vertical rod, a horizontal rod fixedly disposed at the upper end of the vertical rod, a return spring sleeved on the vertical rod and providing a restoring force, and a striking hammer fixedly disposed at the lower end of the vertical rod.

[0023] By adopting the above technical solution, the striking component has a simple and reliable structure. The return spring ensures that the striking hammer quickly returns to its original position after each strike, preparing for the next strike and ensuring the stability of the striking frequency. The striking hammer made of rubber can generate sufficient striking force without causing hard damage to the surface of the cylinder.

[0024] Optionally, the drive assembly includes a rotating shaft rotatably mounted on the mounting plate and an eccentric wheel fixedly sleeved on the rotating shaft and abutting against the striking assembly.

[0025] The power assembly includes a motor fixedly mounted on a mounting plate, and a sprocket and chain connecting the motor output shaft and the rotating shaft.

[0026] By adopting the above technical solution, the eccentric wheel is rotated by a motor drive and sprocket chain transmission, thereby converting the continuous rotational motion into a smooth and regular reciprocating lifting motion to drive the hammer. This transmission method works smoothly and can provide continuous and uniform striking power, further ensuring the stability and automation level of the striking process.

[0027] In summary, this application has the following technical effects:

[0028] 1. By setting up an overall frame consisting of a base plate, a buffer mechanism, a clamping mechanism, a lifting mechanism, a sliding mechanism, and a striking mechanism, and placing the striking end of the striking mechanism above the clamping mechanism, the three-way catalytic converter cylinder to be tested can be stably clamped and receive a stable striking force from above; the buffer spring and limit bolt in the buffer mechanism work together to provide buffer descent space for the cylinder when the striking force is too large, effectively avoiding human damage to the internal structure of the cylinder caused by excessive impact force, thus facilitating stable and reliable striking inspection;

[0029] 2. By setting up a placement block, connecting column, compression spring, clamping block, and screw, the screw adjusts the position of the clamping block, and the compression spring provides continuous clamping force, which can adapt to cylinders of different sizes and achieve fast and stable clamping, providing a solid benchmark for subsequent impact testing and avoiding the instability of manual hand-held operation.

[0030] 3. By setting up a placement groove and an arc-shaped surface, a containment structure with a range of more than 180° is formed, which can better fit the outer wall of the cylinder, increase the contact area, and make the cylinder less likely to shift or rotate during the tapping process, thus ensuring the accuracy of the tapping position and the reliability of the test results.

[0038] The present application will be further described in detail below with reference to the accompanying drawings.

[0039] This application discloses a three-way catalytic converter testing station, referring to... Figure 1 The inspection platform includes a rectangular, horizontally arranged base plate 1, a buffer mechanism 2 arranged on the upper surface of the base plate 1, a clamping mechanism 3 arranged on the upper part of the buffer mechanism 2, a lifting mechanism 4 arranged vertically on the upper surface of the base plate 1 and spaced apart from the buffer mechanism 2, a sliding mechanism 5 arranged on the top lifting end of the lifting mechanism 4, and a striking mechanism 6 connected to the sliding end of the sliding mechanism 5. The striking end of the striking mechanism 6 is located above the clamping mechanism 3. After the three-way catalytic converter cylinder is clamped on the clamping mechanism 3, the striking end of the striking mechanism 6 can perform a striking test on the outer wall of the cylinder.

[0040] Combination Figure 1 and Figure 2The buffer mechanism 2 includes a vertically arranged column 21 with its lower end fixed to the upper surface of the base plate 1, a buffer spring 22 with its lower end fixed to the upper surface of the column 21, a sleeve 23 with a closed end and an open end respectively, the open end of which is sleeved around the buffer spring 22 and the column 21, and a limiting bolt 24 threadedly connected to the outer wall of the sleeve 23 near the open end. In this embodiment, four columns 21 are arranged in a rectangular pattern, and the columns 21 are adapted to the sleeves 23. A limiting groove (not shown in the figure) is formed on the outer wall of the column 21 along its length direction. The two ends of the limiting groove are respectively arranged at intervals with the two ends of the column 21. The limiting bolt 24 slides in the limiting groove. When the inner wall of the closed end of the sleeve 23 abuts against the upper end of the buffer spring 22, the limiting bolt 24 is located at the upper end of the limiting groove. When the three-way catalytic converter is clamped on the clamping mechanism 3 and struck by the striking mechanism 6, if the striking force is too great, the buffer mechanism 2 can provide space for the three-way catalytic converter to descend, thereby helping to protect the three-way catalytic converter.

[0041] Reference Figure 3 The clamping mechanism 3 includes a placement block 31 fixed to the upper end of four sleeves 23, a connecting post 32 horizontally arranged and slidably arranged on the placement block 31, a compression spring 33 sleeved on the connecting post 32, a clamping block 34 fixed to one end of the connecting post 32, and a screw 35 threadedly connected to the placement block 31 and abutting against the clamping block 34. The top of the placement block 31 has a semi-circular arc-shaped placement groove 311, the opening of which faces upwards and away from the lifting mechanism 4. A clearance groove 312 is provided on the lower side of the placement groove 311, and the clamping block 34 is movably disposed within the clearance groove 312. Two mounting holes 313 are also provided on the placement block 31, and the screw 35 is located between the two mounting holes 313. The mounting hole 313 connects the outer wall of the placement block 31 away from the lifting mechanism 4 and the clearance groove 312. The mounting hole 313 is a countersunk hole, and the diameter of the mounting hole 313 at one end of the outer wall of the placement block 31 is larger than the diameter of the mounting hole 313 at one end of the clearance groove 312. The connecting column 32 is movably inserted into the mounting hole 313, and the diameter of the connecting column 32 is smaller than the diameter of the mounting hole 313, thereby providing the connecting column 32 with room to move.

[0042] Reference Figure 3 One end of the connecting column 32 is integrally machined into a limiting ridge 321. The diameter of the limiting ridge 321 is larger than the diameter of the connecting column 32, and the diameter of the limiting ridge 321 is smaller than the larger diameter of the mounting hole 313. The end of the connecting column 32 facing away from the limiting ridge 321 is fixedly connected to the clamping block 34. The clamping block 34 is machined into an arc-shaped surface on the side facing the placement groove 311, which cooperates with the placement groove 311 to form an arc greater than 180°, thereby enabling stable clamping of the cylinder.

[0043] Reference Figure 4The lifting mechanism 4 includes a vertically arranged mounting shell 41 with its lower end fixed to the base plate 1, a horizontally arranged limiting plate 42 fixed inside the mounting shell 41, a vertically arranged lifting rod 43 that movably passes through the upper end of the mounting shell 41 and the limiting plate 42, a horizontally arranged rotating shaft 44 that rotates within the mounting shell 41 via a bearing (not shown in the figure), a gear 45 sleeved and fixed to the rotating shaft 44, an L-shaped connecting rod 46 with one end fixed to the end of the rotating shaft 44 located outside the mounting shell 41, and a positioning component 47 disposed outside the mounting shell 41.

[0044] The mounting housing 41 has closed ends at both the top and bottom. The mounting housing 41 and the column 21 are spaced apart. A limiting plate 42 is located in the middle of the mounting housing 41. The limiting plate 42 has a through hole adapted to the end face of the lifting rod 43, through which the lifting rod 43 movably passes. Multiple continuous toothed grooves 431 are formed along the length of the outer wall of the lifting rod 43, and a gear 45 meshes with the toothed grooves 431. An abutment plate 432 is fixedly connected to the lower end of the lifting rod 43. At least two adjacent sidewalls of the abutment plate 432 abut against the inner wall of the mounting housing 41, thereby restricting the lifting rod 43. When the abutment plate 432 is against the lower inner wall of the mounting housing 41, the upper end of the lifting rod 43 is not lower than the upper outer wall of the mounting housing 41. The rotating shaft 44 and the gear 45 are both located between the upper end of the mounting housing 41 and the limiting plate 42. An L-shaped connecting rod 46 facilitates the rotation of the rotating shaft 44.

[0045] Reference Figure 4 The positioning assembly 47 includes a ratchet 471 sleeved and fixed to the rotating shaft 44, a pawl 472 with one end rotating on the outer wall of the mounting housing 41 and the other end located above the ratchet 471, a pressure plate 473 with one end fixed to the rotating end of the pawl 472, and a spring piece 474 with one end fixed to the outer wall of the mounting housing 41 and the other end pressed against the upper part of the pawl 472. The spring piece 474 and the pressure plate 473 are located on both sides of the pawl 472. When the lifting rod 43 is raised, the spring piece 474 presses against the pawl 472 to stably engage the pawl 472 with the ratchet 471, thereby ensuring the stability of the lifting rod 43 after it is raised.

The upper surface of the connecting plate 51 has a groove, the length of which is perpendicular to the length of the screw 35. The width of the groove opening is smaller than the width of its bottom. The shape of the limiting block 54 matches the shape of the groove opening. Two limiting blocks 54 are provided and respectively located at both ends of the groove, and are fixedly connected to the connecting plate 51 by bolts.

[0047] Reference Figure 6The slider 52 includes an integrally formed sliding part 521 and a protrusion 522. The shape of the sliding part 521 is adapted to the groove opening and slides in the groove. The protrusion 522 protrudes out of the groove opening. The protrusion 522 and the sliding part 521 are provided with through threaded holes. The positioning bolt 53 is threaded into the threaded hole. Tightening the positioning bolt 53 can position the slider 52 in the groove.
