[0002] The double oil-impregnated bearing is a precision mechanical part with self-lubricating characteristics and structural stability, and the core advantage is to realize long-term maintenance-free operation through unique pore structure design. The bearing takes metal powder (such as iron-based and copper-based) as a matrix, forms a solid body with a honeycomb-like micro-pore through pressing and sintering process, and then makes the lubricating oil fully penetrate into the pore through vacuum oil immersion technology, thereby constructing a "solid-liquid coexistence" composite lubrication system.

By fixing the first cylinder 41, the stability of the first cylinder 41 when driving the first hydraulic rod 42 to move is ensured, and the reliable operation of the positioning mechanism 4 is ensured.

[0034] Further, as shown, Figures 1-8 As shown, the press-fitting mechanism 5 includes a second cylinder 51, the second cylinder 51 is installed on the rack 1, and a second hydraulic rod 52 is installed on the second cylinder 51, the output end of the second hydraulic rod 52 penetrates the rack 1 and is fixedly connected with a pressing plate 53, the lower end of the pressing plate 53 is fixedly installed with a threaded mounting block 54, the threaded mounting block 54 is threadedly connected with a press-fitting rod 55, the press-fitting rod 55 is fixedly connected with a pressing head 56 at the end away from the threaded mounting block 54, the pressing head 56 corresponds to the guide column 43, and a clearance hole 57 is formed in the press-fitting rod 55, a pressing hole 58 is formed in the pressing head 56, the pressing hole 58 communicates with the clearance hole 57, and the press-fitting mechanism 5 further includes a press-fitting plate 59, two guide rods 510 are fixedly installed on the press-fitting plate 59, the guide rods 510 penetrate the pressing plate 53 and are fixedly connected with the rack 1 at the end away from the press-fitting plate 59, springs 511 are sleeved on the outer sides of the guide rods 510, one end of each spring 511 is connected with the pressing plate 53, and the other end of each spring 511 is connected with the press-fitting plate 59, a through hole 591 is formed in the press-fitting plate 59, and the pressing head 56 movably penetrates the through hole 591. When press-fitting is needed, the second cylinder 51 is started to drive the second hydraulic rod 52 to extend downward, the output end penetrates the rack 1 to push the fixed pressing plate 53 downward, the threaded mounting block 54 at the lower end of the pressing plate 53 is connected with the press-fitting rod 55 in a threaded manner, and the pressing head 56 can be replaced according to different requirements, so that the press-fitting rod 55 moves downward together with the pressing plate 53, the pressing head 56 on the press-fitting rod 55 is opposite to the guide column 43, and can be accurately positioned at the workpiece 8 to be press-fitted with the oil-impregnated bearing, so as to ensure the accuracy of the press-fitting process.

[0035] When the pressing head 56 penetrates the through hole 591 on the press-fitting plate 59, the first oil-impregnated bearing workpiece 6 is extruded, the second oil-impregnated bearing workpiece 7 is first pressed into the workpiece 8 to be press-fitted with the oil-impregnated bearing, and then the first oil-impregnated bearing workpiece 6 is subsequently pressed into the workpiece 8 to be press-fitted with the oil-impregnated bearing. After the press-fitting is completed, the second cylinder 51 drives the second hydraulic rod 52 to retract, and the elastic restoring force of the spring 511 can assist the pressing plate 53 to quickly return, so as to prepare for the next press-fitting. The entire press-fitting mechanism 5 cooperates with the second cylinder 51, the second hydraulic rod 52, the pressing plate 53, the press-fitting rod 55, the pressing head 56, and the spring 511, so as to realize accurate, stable and safe press-fitting operation.

[0036] Meanwhile, the relief hole 57 on the press-in rod 55 and the press hole 58 on the press head 56 are connected to form a through channel, providing a channel for the press-in operation. When the press plate 53 moves downward, the spring 511 outside the sleeve is compressed when the press plate 53 moves downward, providing a buffer force through elastic deformation, avoiding damage caused by rigid collision between the press head 56 and the workpiece, and the guide rod 510 is fixed at one end of the machine frame 1 and penetrates the press plate 53 at the other end, ensuring the stability of the movement of the press plate 53.

The diameter of the press hole 58 is consistent with the outer diameter of the first oil-containing bearing workpiece 6. The diameter of the relief hole 57 is greater than the outer diameter of the guide column 43, which allows the guide column 43 to pass through the relief hole 57 smoothly during the press-in process, avoiding interference between the two and ensuring smooth press-in action. At the same time, the diameter of the relief hole 57 is less than the outer diameter of the first oil-containing bearing workpiece 6, which limits the first oil-containing bearing workpiece 6 to be located at the position of the press head 56, preventing it from falling into the relief hole 57 and ensuring the accuracy of the workpiece position. The diameter of the press hole 58 is consistent with the outer diameter of the first oil-containing bearing workpiece 6. When the press-in starts, the press head 56 acts on the first oil-containing bearing workpiece 6, which can tightly fit the workpiece and apply uniform and stable pressure, accurately press-in the first oil-containing bearing workpiece 6 into the workpiece 8 to be press-in, thereby ensuring the orderly cooperation of each component during the press-in process and improving the precision and efficiency of the press-in.
