Description

Technical Field

[0001] This utility model relates to the field of riveting technology, specifically a rocker arm assembly for a bushing riveting process. Background Technology

[0002] Riveting is a machining process that uses external pressure to cause plastic deformation between the riveted part and the base material, thereby achieving a reliable connection. Usually, when connecting the riveted part to the base material, the riveting process is mostly used for reliable connection and fixation. When producing rocker arms, the rocker arm assembly using the bushing riveting process is required.

[0003] The existing technology has the following problems:

[0004] When connecting and fixing the bushing to the rocker arm, argon arc welding is usually used. Argon gas is required during the welding process. Argon is an inert gas and has certain hazards, which can easily cause harm to the operator. At the same time, it is not convenient to install and disassemble the fixed shaft, making the production process more troublesome. Utility Model Content

[0016] (III) Beneficial Effects

[0017] By inserting the bushing body into the fixing groove, the riveting step is made to fit against the inner wall of the fixing groove. By placing the riveting cylinder around the limiting step and moving the riveting cylinder downward to compress the riveting step, the top of the riveting step deforms and expands outward. This allows the deformed part of the riveting step to fit against the top of the rocker arm body, facilitating the riveting and fixing of the riveting step to the inner side of the rocker arm body. Simultaneously, it fixes the bushing body. By using the riveting process to connect and fix the bushing body to the inner side of the rocker arm body, the use of argon arc welding to connect the bushing body and the rocker arm body is avoided. The design ensures that the use of argon gas can be fixed in place, avoiding the harm to operators and improving the efficiency of fixing. By inserting a hex wrench into the inside of the first and second fixed shafts, they can be rotated. The first threaded post facilitates the installation and removal of the first fixed shaft from the rocker arm body, and the second threaded post facilitates the installation and removal of the second fixed shaft from the rocker arm body.

Figure 1-5 As shown, the device includes a rocker arm body 1, a bushing body 2 fixedly installed on the inner side of the rocker arm body 1, a riveting step 8 provided on the outer periphery of the bushing body 2, a limiting step 9 provided on the outer periphery of the bushing body 2 at the top of the riveting step 8, a first fixed shaft 4 threadedly connected to the top of the rocker arm body 1 on one side of the bushing body 2, a first threaded post 11 fixedly installed at the bottom of the first fixed shaft 4, the first threaded post 11 extending to the inner side of the rocker arm body 1 and threadedly connected to the rocker arm body 1, a second fixed shaft 6 threadedly connected to the top of the rocker arm body 1 on the other side of the bushing body 2, a second threaded post 13 fixedly installed at the bottom of the second fixed shaft 6, the second threaded post 13 extending to the inner side of the rocker arm body 1 and threadedly connected to the rocker arm body 1, a first hexagonal groove 14 opened on the inner side of the first fixed shaft 4 and the first threaded post 11, and a second hexagonal groove 15 opened on the inner side of the second fixed shaft 6 and the second threaded post 13.

[0027] A support base 3 is fixedly installed on the top of the rocker arm body 1 around the first threaded column 11. The support base 3 is located at the bottom of the first fixed shaft 4 and is in contact with the first fixed shaft 4.

[0028] A support pad 5 is fixedly installed on the top of the rocker arm body 1 around the second threaded column 13. The support pad 5 is located at the bottom of the second fixed shaft 6 and is in contact with the second fixed shaft 6.

[0029] A fixing groove 7 is provided on the inner side of the rocker arm body 1, and the riveting step 8 is located inside the fixing groove 7 and fits against the inner wall of the fixing groove 7.

[0030] A first threaded hole 10 is provided on the inner side of the rocker arm body 1 on one side of the bushing body 2, and a first threaded post 11 is located inside the first threaded hole 10 and is threadedly connected to the first threaded hole 10.

[0032] The first threaded post 11 and the second threaded post 13 have the same diameter. The first hexagonal groove 14 and the second hexagonal groove 15 have the same shape and size. The first hexagonal groove 14 passes through the first fixed shaft 4 and the first threaded post 11, and the second hexagonal groove 15 passes through the second fixed shaft 6 and the second threaded post 13.

[0033] The working principle of the rocker arm assembly in a bushing riveting process based on the embodiment is as follows: by inserting the bushing body 2 into the inner side of the fixing groove 7, the outer periphery of the riveting step 8 is made to fit against the inner wall of the fixing groove 7.

[0034] By placing the riveting cylinder around the periphery of the limiting step 9 and pressing the riveting step 8 downwards, the top of the riveting step 8 deforms and expands outwards. This allows the deformed part of the riveting step 8 to fit against the top of the rocker arm body 1, making it easier to rivet and fix the riveting step 8 to the inside of the rocker arm body 1. At the same time, it fixes the bushing body 2. By using the riveting process to connect and fix the bushing body 2 to the inside of the rocker arm body 1, it avoids the use of argon arc welding to fix the bushing body 2 and the rocker arm body 1, avoids the harm caused to the operator by using argon gas, and can improve the efficiency of fixing.

[0035] By inserting a hex wrench into the first hexagonal slot 14, the first fixed shaft 4 can be rotated easily. By screwing the first threaded post 11 into the inside of the first threaded hole 10, the first fixed shaft 4 can be installed easily. The first fixed shaft 4 can be supported by the support base 3. By screwing the first threaded post 11 off, the first threaded post 11 can be separated from the first threaded hole 10, making it easy to disassemble the first fixed shaft 4.

[0036] By inserting a hex wrench into the second hexagonal slot 15, the second fixed shaft 6 can be easily rotated. By screwing the second threaded post 13 into the inner side of the second threaded hole 12, the second fixed shaft 6 can be installed and fixed. The support pad 5 can support the second fixed shaft 6. By screwing the second threaded post 13 off, the second threaded post 13 can be separated from the second threaded hole 12, making it easy to disassemble the second fixed shaft 6. This makes it easy to install and disassemble the first fixed shaft 4 and the second fixed shaft 6, making disassembly and maintenance simple and quick.

[0037] The first hexagonal groove 14 passes through the first fixed shaft 4 and the first threaded post 11, while the second hexagonal groove 15 passes through the second fixed shaft 6 and the second threaded post 13. This reduces the overall weight and facilitates cleaning of the first hexagonal groove 14 and the second hexagonal groove 15, preventing foreign objects from entering the first hexagonal groove 14 and the second hexagonal groove 15 and making it difficult to insert the hexagonal wrench.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
