[0041] Please refer to Figures 1-5 , the present invention provides an auxiliary pressing device for assembling a bushing and a joint with high machining accuracy, which includes:

[0042] A substrate 1, on which an installation frame 2 is provided;

[0043] At least one positioning block 3, on which a positioning groove 4 is provided, and the positioning groove 4 is adapted to the size of the plastic joint 5;

[0044] The pressing assembly includes a driving component 6, a first connecting plate 7, and a rubber sleeve fixing column 8. The driving component 6 is installed on the mounting bracket 2. The first connecting plate 7 is connected to the driving component 6. The driving component 6 drives the first connecting plate 7 to move vertically. The rubber sleeve fixing column 8 is connected to the driving component 6. The rubber sleeve fixing column is used to fix the rubber sleeve 21.

[0045] A tensioning component is arranged on the rubber sleeve fixing column 8.

[0046] In one implementation, the tensioning component includes a driving cylinder 9, a movable rod 10, and a ball 11. The driving cylinder 9 is arranged on the first connecting plate 7. The movable rod 10 is connected to the driving cylinder 9. The movable rod 10 passes through a first through hole of the rubber sleeve fixing column 8. A limiting space 12 is arranged on the movable rod 10. The ball 11 is movably connected in the limiting space 12. At least two second through holes 13 are arranged on the side wall of the rubber sleeve fixing column 8. A part of the ball 11 is located in the second through hole 13. A thin rod section 14 is arranged on the movable rod 10. The connection between the thin rod section 14 and the movable rod 10 transitions through a conical surface. The thin rod section and the two conical surfaces form a limiting space. During use, initially, the ball is located in the limiting space. The rubber sleeve is sleeved on the rubber sleeve fixing column. The driving cylinder drives the movable rod to move, so that the conical surface contacts the ball, thereby forcing the ball to partially enter the second through hole and can protrude from the surface of the rubber sleeve fixing column, so that the diameter of the rubber sleeve fixing column can be increased to fix the rubber sleeve. After the rubber sleeve is installed, the driving cylinder drives the movable rod to move again, so that the ball separates from the conical surface and enters the thin rod section, so that the ball enters the inside of the rubber sleeve fixing column, which is convenient for separating the rubber sleeve from the rubber sleeve fixing column and realizes the purpose of convenient material discharging.

[0047] In another implementation, the tensioning component is a sealing film. An inflation space is arranged between the sealing film and the rubber sleeve fixing column 8. An inflation port is arranged on the sealing film. The sealing film is sleeved on the rubber sleeve fixing column. Initially, there is no air in the inflation space. After the rubber sleeve is sleeved on the rubber sleeve fixing column, inflation is carried out through the inflation port to make the sealing film expand, so that the diameter of the rubber sleeve fixing column can be increased to fix the rubber sleeve. After the rubber sleeve is installed, the inflation port sucks air to suck away the gas in the inflation space, and the rubber sleeve fixing column returns to its original state, which is convenient for separating the rubber sleeve from the rubber sleeve fixing column and realizes the purpose of convenient material discharging.

[0048] At least one buffer component is arranged on the first connecting plate 7. Guide components are respectively arranged at both ends of the first connecting plate 7. It can improve the stability during the pressing process.

[0049] In one embodiment, the guiding member includes a second connecting plate 15, a connecting rod 16, and a guiding rod 17. The second connecting plate 15 is connected to the driving member 6. Both ends of the second connecting plate 15 are respectively connected to one of the connecting rods 16. The connecting rod 16 is connected to the first connecting plate 7. The first connecting plate 7 is slidably connected to the guiding rod 17. The guiding rod 17 is connected to the substrate 1. This can make the movement of the first connecting plate smoother, without deviation, and improve the assembly quality.

[0050] The buffering member includes a spring 18, a third connecting plate 19, and a T-shaped guide post 20. The third connecting plate 19 is connected to the top of the guiding rod 17 and is located above the first connecting plate 7. The T-shaped guide post passes through the third connecting plate 19 and is connected to the first connecting plate 7. The spring 18 is sleeved on the T-shaped guide post 20. When the first connecting plate moves downward, it drives the T-shaped guide post to move downward and compress the spring, which can prevent the first connecting plate from moving downward too fast and can achieve the purpose of protection.

[0051] The driving member 6 is an electric cylinder or a cylinder. Specifically, it is a cylinder.

[0052] Working principle: Select the corresponding rubber bushing positioning block and rubber sleeve fixing post, and install them on the tooling fixing substrate and the first connecting plate respectively. Adjust the pressing-in stroke according to the requirements. Install the rubber sleeve and the plastic joint on the rubber sleeve fixing post and the positioning groove respectively. Start the equipment. The cylinder drives the first connecting plate to move downward and press tightly along the guiding groove. After pressing to the adjusted stroke, it automatically opens. Take out the tightly pressed product and perform the work of the next cycle. Therefore, in the present invention, through the provided positioning groove, it is convenient to quickly fix the plastic joint. Through the provided rubber sleeve fixing post, it is convenient to quickly fix the rubber sleeve. Then, the driving member drives the first connecting plate to move downward, so that the rubber sleeve fixing post on the first connecting plate can move downward to insert the rubber sleeve into the plastic joint, realizing automatic pressing, avoiding the error of manual pressing, improving the efficiency, having a high degree of automation, and reducing the labor intensity. By replacing the positioning block and the rubber sleeve fixing post, it can be applicable to the pressing of various rubber bushing and plastic joint products, and has a wide application range. By providing a tensioning member on the rubber sleeve fixing post, when installing the rubber sleeve, the tensioning member contracts, which can facilitate the rubber sleeve to be sleeved on the rubber sleeve fixing post. After the rubber sleeve is installed, the tensioning member expands, which can make the rubber sleeve fixed more firmly and prevent the rubber sleeve from falling off. Then, when the rubber sleeve is pressed into the plastic joint, the tensioning member contracts again, so that the rubber sleeve fixing post can be withdrawn from the rubber sleeve, achieving the purpose of facilitating the discharging of the material.

[0053] As described above, it is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
