Finally, the shell edge N2-1 and the shell edge N2-2 of the housing N2 that are higher than the bearing N1 are curled inwards by 90 degrees using a tool to fix the position of the bearing N1, the large gasket N3, and the small gasket N4. When the large gasket N3 is assembled to the housing N2, due to functional requirements, such as Figure 2 As shown, the two grooves N3-2 and N3-3 of different shapes on the gasket need to be respectively mounted on the shell edges N2-1 and N2-2; therefore, during installation, the relative position relationship between the large gasket N3 and the shell N2, as well as the angle position of the protrusion N3-1 need to be predefined; that is, before the large gasket N3 is assembled, it needs to be adjusted to a preset angle. In the prior art, because there is a protrusion N3-1 on the large gasket N3, when multiple large gaskets N3 are stacked, the protrusion N3-1 of the lower large gasket N3 will buckle into the bottom end of the protrusion N3-1 of the upper large gasket N3, and it is difficult to achieve automatic separation using a device, so the angle of the large gasket N3 before being installed inside the shell N2 is manually determined and adjusted by the operator; manually adjusting the position angle of the large gasket before installation is not only inefficient, but also prone to errors in angle adjustment after long-term work.

If the large gaskets N3 to be processed stacked on the gasket material rod 1 are not placed neatly, after entering the inner cavity of the gasket guide seat 2, the large gaskets N3 to be processed will be gradually arranged in the process of falling due to gravity, and then enter the gasket material taking port 26 below from the inner cavity outlet of the gasket guide seat 2, ensuring that the large gaskets N3 to be processed that enter the gasket material taking port 26 all enter with the gasket material rod 1 as the center of the circle, and can just fall into the gasket discharge claws 20 in the gasket clamping and fixing knot below.

[0027] The gasket clamping and fixing structure is arranged at the bottom of the gasket material rod 1, below the inner cavity outlet of the gasket material guide seat 2 and above the gasket material taking port 26;

[0028] The gasket clamping and fixing structure includes two gasket discharging claws 20 which are symmetrically arranged above the gasket feeding port 26 with the gasket material rod 1 as the center, and the two gasket discharging claws 20 are driven by the discharging claw cylinder 6 respectively; the two gasket discharging claws 20 clamp the large gasket N3 to be processed on the gasket material rod 1 from both sides, so that the large gasket N3 to be processed piled on the top stops descending, ensuring that only the large gasket N3 to be processed located below the gasket discharging claws 20 can be taken away by the gasket feeding structure.

[0029] The gasket taking port 26 and the gasket discharging port 23 are respectively arranged at the upper position of the feeding track of the gasket feeding structure; the gasket feeding structure takes out the large gasket N3 to be processed from the gasket taking port 26 and sends it to the gasket discharging port 23, and the angle adjustment structure located at the gasket discharging port 23 adjusts the large gasket N3 to be processed to a horizontal angle before assembly;

[0032] The gasket taking platform 4 is a bowl-shaped structure, and the diameter of the head of the gasket taking platform 4 is larger than the outlet of the gasket feeding hole 25. The head of the gasket taking platform 4 is movably connected to the outlet of the gasket feeding hole 25, and the bottom of the gasket taking platform 4 extends vertically downward from the outlet of the gasket feeding hole 25; Figure 6 As shown, the gasket feeding structure also includes a gasket feeding cylinder 7 installed on the extension line of the gasket material rod 1, and the gasket feeding cylinder 7 is fixed to the upper end surface of the mounting seat 8 directly below the gasket feeding port 26; a feeding platform sliding mounting seat 24 is arranged at the top of the vertically upward piston rod of the gasket feeding cylinder 7, and a slide rail structure is arranged on the top of the feeding platform sliding mounting seat 24; a slider structure is arranged at the bottom of the gasket feeding platform 4, and is slidably installed in the slide rail structure in the feeding platform sliding mounting seat 24 in the moving direction of the feeding slide 3;

[0033] After the gasket picking platform 4 picks up the material, the gasket picking cylinder 7 retracts the gasket picking platform 4. When the gasket picking platform 4 drops to the lowest position, the gasket picking platform 4 is completely located in the gasket unloading hole 25 in the feeding slide 3; the gasket feeding cylinder 5 is started, pushing the feeding slide 3 to slide horizontally along the feeding slide rail structure 21, and the slider structure at the bottom of the gasket picking platform 4 slides out from the slide rail at the top of the picking platform sliding mounting seat 24 until the feeding slide 3 is pushed to send the gasket picking platform 4 to the gasket discharge port 23, and the gasket feeding cylinder 5 stops; when the gasket feeding cylinder 5 After reverse start, the feeding slide 3 is pushed to slide horizontally in the reverse direction along the feeding slide rail structure 21.
