Description

Technical Field

[0001] This utility model relates to the field of three-way catalytic converter disassembly and assembly technology, and in particular to an auxiliary tooling for disassembling and assembling automotive three-way catalytic converters. Background Technology

[0002] The three-way catalytic converter is a key environmental protection device in the automotive exhaust system. Its core is a honeycomb ceramic carrier coated with precious metal catalysts such as platinum, rhodium, and palladium. Through oxidation-reduction reactions, it converts carbon monoxide, hydrocarbons, and nitrogen oxides in the exhaust gas into harmless carbon dioxide, water, and nitrogen. It is a core component for vehicles to meet emission standards. When disassembling and assembling a three-way catalytic converter, the exhaust pipe needs to be removed, and then the three-way catalytic converter needs to be cut off from one end of the exhaust pipe. Therefore, auxiliary tools are required. However, in current auxiliary tooling, the positioning plate is mostly fixedly connected to the tooling body, such as by welding or bolting. When it is necessary to disassemble and install different models of three-way catalytic converters, it is inconvenient to replace the positioning plate. The disassembly process of the fixed connection is time-consuming and laborious, requiring additional tools. Frequent disassembly can easily lead to wear on the connection parts, affecting the overall stability of the tooling. Moreover, it is difficult for the replaced positioning plate to quickly and accurately align with the tooling body, which may result in positioning deviation, thereby affecting the disassembly and installation accuracy and efficiency of the three-way catalytic converter, increasing the difficulty of operation and the potential risk of component damage. Therefore, this utility model proposes an auxiliary tooling for disassembling and installing automotive three-way catalytic converters to solve the above problems. Utility Model Content

[0013] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0014] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes an auxiliary tool for disassembling and assembling a vehicle three-way catalytic converter, including a base plate 1.

A hydraulic cylinder 4 is installed at the bottom of the top plate 3, and an mounting plate 5 is installed at the bottom of the hydraulic cylinder 4. An installation mechanism is provided below the mounting plate 5, and a positioning plate 6 is installed below the installation mechanism. A dust collection mechanism is provided at the rear end of the upper part of the base plate 1. In use, the exhaust pipe and the three-way catalytic converter are placed on the base plate 1, and then the hydraulic cylinder 4 is activated to move the mounting plate 5 and the positioning plate 6 downwards. The three positioning plates 6 are used to position the exhaust pipe and the three-way catalytic converter, making the three-way catalytic converter more stable during disassembly. Then, external tools are used to disassemble and install the three-way catalytic converter. The installation mechanism includes an installation cavity 7, a connecting block 8, a positioning hole 9, a fixing cavity 10, a pull pin 11, and a telescopic spring 12. The installation cavity 7 is installed at the bottom end of the installation plate 5. A groove is formed inside the installation cavity 7. The connecting block 8 is installed inside the installation cavity 7, and a positioning hole 9 is formed inside the connecting block 8. The fixing cavity 10 is installed at one end of the installation cavity 7. A pull pin 11 is inserted through the fixing cavity 10, and one end of the pull pin 11 extends into the positioning hole 9. A telescopic spring 12 is provided on the outer wall of the pull pin 11 and is installed inside the fixing cavity 10. The positioning hole 9 and the pull pin 11... The positioning holes 9 and the pull pin 11 are mutually compatible, forming a locking structure. When the positioning plate 6 needs to be replaced, the operator pulls the pull pin 11 to disengage it from the positioning hole 9, allowing the positioning plate 6 to be easily removed. Then, the new positioning plate 6 is taken out, and the connecting block 8 is inserted into the installation cavity 7. At this time, the pull pin 11 is released, and the telescopic spring 12 is subjected to elastic force to extend the pull pin 11, causing the pull pin 11 to engage with the positioning hole 9, thus completing the convenient installation of the positioning plate 6. The positioning plate 6 can be easily disassembled and installed, making it more convenient and faster to replace, thereby greatly improving the convenience of the tooling in use.

[0015] The dust collection mechanism includes a storage chamber 13, a negative pressure fan 14, a connecting hose 15, a dust suction port 16, and a movable structure. The storage chamber 13 is installed at the rear end of the top of the base plate 1. The negative pressure fan 14 is installed above the storage chamber 13, and one end of the negative pressure fan 14 is connected to the top of the storage chamber 13. The connecting hose 15 is installed at one end of the storage chamber 13, and the dust suction port 16 is installed at one end of the connecting hose 15. The movable structure includes a fixed plate 17, an electromagnetic slide rail 18, an electromagnetic slider 19, an electric telescopic rod 20, and a connecting rod 21. The fixed plate 17 is installed at the top of the base plate 1, and the electromagnetic slide rail 18 is installed at the top of the fixed plate 17. An electromagnetic slider 19 is installed on the outer wall of the electromagnetic slide rail 18. An electric telescopic rod 20 is installed on the top of the electromagnetic slider 19. A connecting rod 21 is installed on one end of the electric telescopic rod 20. One end of the connecting rod 21 is connected to one end of the dust suction port 16. In use, the negative pressure fan 14 is started. With the cooperation of the dust suction port 16 and the connecting hose 15, dust and debris are sucked into the interior of the storage chamber 13. At this time, the electromagnetic slide rail 18 is started to move the electromagnetic slider 19, which in turn moves the dust suction port 16, so as to perform a more comprehensive suction treatment on the base plate 1, making the base plate 1 cleaner and tidier during use, thereby greatly improving the cleanliness of the tooling during use.

[0016] The connecting rod 21 can be made of memory soft aluminum alloy, which can adjust the angle of the suction port 16, thus making the suction effect of the tool better.

[0017] The positioning plate 6 has an arc-shaped design, and a plastic anti-slip pad is provided on the inner side of the positioning plate 6, so that the car exhaust pipe and the three-way catalytic converter are not easy to slide during disassembly and assembly.

[0018] Working principle: The operator first places the exhaust pipe and catalytic converter above the base plate 1. Then, the hydraulic cylinder 4 is activated to move the mounting plate 5 and positioning plate 6 downwards. The three positioning plates 6 are used to position the exhaust pipe and catalytic converter, making the catalytic converter more stable during disassembly. External tools are then used to disassemble and install the catalytic converter. After installation, the hydraulic cylinder 4 is activated to move the positioning plate 6 upwards, allowing the catalytic converter to be removed. At this point, the negative pressure fan 14 is activated, and the dust suction port 16 and connecting hose 15 work together to draw dust and debris into the storage tank. Inside cavity 13, the electromagnetic slide rail 18 is activated to move the electromagnetic slider 19, which in turn moves the suction port 16 to perform a more comprehensive adsorption treatment on the base plate 1. When the positioning plate 6 needs to be replaced, the operator pulls the pull pin 11 to disengage the pull pin 11 from the positioning hole 9, allowing the positioning plate 6 to be easily removed. Then, the new positioning plate 6 is taken out, and the connecting block 8 is inserted into the installation cavity 7. At this time, the pull pin 11 is released, and the telescopic spring 12 is subjected to elastic force to extend the pull pin 11, so that the pull pin 11 engages with the positioning hole 9, completing the convenient installation of the positioning plate 6.
