[0020] like Figure 1 and Figure 2 As shown, a cylinder swing arm connection structure of an automatic assembly line includes a wire car positioning claw 7, a rotating shaft 6 arranged on the wire car positioning claw 7, two bearing seats 8 for fixing the rotating shaft 6, a control cylinder 5 for driving the rotating shaft 6 to rotate, and a driving swing arm 11 between the piston rod of the control cylinder 5 and the rotating shaft 6, one end of the driving swing arm 11 is rotatably connected to the piston rod of the control cylinder 5, and the other end is fixedly connected to the rotating shaft 6 between the two bearing seats 8, one end of the driving swing arm 11 is provided with a positioning hole 1, a wear-resistant block 2 is provided in the positioning hole 1, and a transfer hole 3 is provided on the wear-resistant block 2, a U-shaped connecting block 4 is provided on the piston rod of the control cylinder 5, and the driving swing arm 11 is installed in the U-shaped groove of the connecting block 4 through a pin shaft.

[0021] At present, one end of the rotating shaft 6 of the connecting structure is fixed on the wire car positioning claw 7. When the rotating shaft 6 rotates, the wire car positioning claw 7 can be driven to rotate, and the lower end of the rotating shaft 6 is positioned on the frame of the packaging equipment through two bearing seats 8. One end of the driving swing arm 11 is fixedly connected to the rotating shaft 6, generally relatively fixed by a pin shaft, and the other end is rotationally connected to the piston rod of the control cylinder 5 through a pin shaft. When the piston rod of the control cylinder 5 is telescopically controlled, the driving swing arm 11 can be driven to swing with the rotating shaft 6 as the axis, and finally the rotating shaft 6 and the wire car positioning claw 7 are rotated. However, since the existing driving swing arm 11 and the piston rod connecting end of the control cylinder 5 are circular holes and the rotation of the pin shaft The driving swing arm 11 is generally made of pure copper, and it is easy for the round hole to wear out and cause the entire driving swing arm 11 to need to be replaced. Therefore, in order to solve this technical problem, the driving swing arm 11 is redesigned, wherein the driving swing arm 11 can adopt the original structure, or it can be remade from stainless steel, and then the round hole end of the driving swing arm 11 is enlarged to form a positioning hole 1, and then a wear-resistant block 2 with a transfer hole 3 is installed in the positioning hole 1, and a U-shaped connecting block 4 is provided on the piston rod of the control cylinder 5, and the driving swing arm 11 is installed in the U-shaped groove of the connecting block 4 through a pin shaft, and the connecting block 4 can limit the wear-resistant block 2 to avoid the problem of the wear-resistant block 2 falling during use. At the same time, during the swinging process of the piston rod of the control cylinder 5 and the wear-resistant block 2, the wear area is in the pin shaft and the adapter hole 3 of the wear-resistant block 2. When severe wear occurs, only the pin shaft or the wear-resistant block 2 needs to be replaced to achieve operation again. There is no need to replace the entire swing arm, which effectively reduces the maintenance cost of the assembly line, and has better wear resistance, easy and effective installation and maintenance, simple structure, low cost, and easy modification, which greatly improves the maintenance efficiency and is more conducive to promotion and use.

[0022] As a further improvement, the positioning hole 1 adopts a quadrilateral square hole structure, and the wear-resistant block 2 is embedded and installed in the positioning hole 1.

[0023] The positioning hole 1 adopts a quadrilateral square hole structure. When the wear-resistant block 2 is embedded and installed in the positioning hole 1, an integrated structure can be realized between the two. The wear-resistant block 2 will not rotate during the rotation process, which can avoid the wear of the positioning hole 1 and the need to replace the driving swing arm 11. Especially when the positioning hole 1 adopts a square hole, the installation of the wear-resistant block 2 is simpler and more convenient.

[0024] As a further improvement, the wear-resistant block 2 and the positioning hole 1 are overfitted, and the wear-resistant block 2 and the side surface to be installed in the positioning hole 1 are both provided with an inclined structure of 3 to 5 degrees.

[0025] The overfit between the wear-resistant block 2 and the positioning hole 1 can make the two tighter after installation and easier to disassemble after installation. In order to facilitate the assembly of the wear-resistant block 2 and the positioning hole 1, chamfers are generally formed at the corners of the wear-resistant block 2. At the same time, in order to facilitate faster assembly, an inclined surface structure of 3 to 5° is adopted on the side of the wear-resistant block 2 and the side of the positioning hole 1.

[0026] A further improvement is that a limiting ring 12 protruding inward is provided at the bottom of the positioning hole 1; and the wear-resistant block 2 is made of stainless steel.

[0027] When assembling the wear-resistant block 2, in order to ensure that it does not move downward after installation and cause wear of the connecting block 4, an inwardly protruding limit ring 12 is formed at the bottom of the positioning hole 1, so that a stepped hole structure is formed between the two, which makes it easier to position the wear-resistant block 2 during installation and can avoid excessive problems when knocking it in. During disassembly, since the inner size of the limit ring 12 is larger than the diameter of the adapter hole 3, it can be pushed out by knocking at the bottom, making the disassembly, assembly and replacement of the wear-resistant block 2 more convenient.

[0028] As a further improvement, the rotating shaft 6 is provided with a hexagonal connecting section 9 protruding outward, and the other end of the driving swing arm 11 is provided with a hexagonal connecting hole 10 connected to the hexagonal connecting section 9; the rotating shaft 6 and the driving swing arm 11 are also fixed by a pin shaft.

[0029] Since the connection between the existing rotating shaft 6 and the driving swing arm 11 adopts a circular structure, it is necessary to relatively fix them through a pin shaft. When the pin shaft is aged, it is easy to break. Therefore, in order to solve this problem, an outwardly protruding hexagonal connecting section 9 is formed in the area on the rotating shaft 6 for installing the driving swing arm 11, and the connecting hole on the driving swing arm 11 is also changed to a hexagonal connecting hole 10 connected to the hexagonal connecting section 9, so that the installation process no longer needs to be positioned through a pin shaft, and the problem of the pin shaft breaking and the wire machine positioning claw 7 being difficult to rotate will no longer occur during the rotation process. In order to avoid the problem of inaccurate upper and lower positioning of the connecting end of the driving swing arm 11, a pin shaft is also used to fix the limit between the rotating shaft 6 and the driving swing arm 11. The pin shaft can be positioned by a screw, and it does not need to bear the rotation shear force, so it will not break.

[0030] The above-mentioned implementation modes are only preferred implementation modes of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present application shall fall within the scope of protection required by the present application.
