[0001] The present invention relates to an auxiliary device for press-fitting double oil-impregnated bearings, belonging to the technical field of press-fitting oil-impregnated bearings. Background Art

[0002] Double oil-impregnated bearings are precision mechanical components with both self-lubricating characteristics and structural stability. Their core advantage lies in achieving long-term maintenance-free operation through a unique pore structure design. Such bearings use metal powders (such as iron-based, copper-based) as the matrix, and through pressing and sintering processes, they form a solid with honeycomb-like micropores. Then, through vacuum oil impregnation technology, lubricating oil fully penetrates into the pores to build a "solid-liquid coexistence" composite lubrication system.

[0003] In the traditional press-fitting process of double oil-impregnated bearings, problems such as misalignment and offset often occur during press-fitting due to workpiece positioning deviation, which affects the assembly accuracy and product quality. Moreover, manual operation errors are large and production efficiency is low, making it difficult to meet the requirements of mass production.

Specific embodiments

[0018] The following will cooperate with the drawings and embodiments to detail the implementation manners of the present application, so as to fully understand how the present application uses technical means to solve technical problems and achieve the implementation process of technical effects and implement accordingly.

[0019] As Figures 1-8 shown, the double oil-impregnated bearing press-fitting auxiliary device provided in this embodiment includes a frame 1, a fixed block 2 is installed on the frame 1, a groove 3 is opened on the fixed block 2, a positioning mechanism 4 is arranged inside the groove 3, and a press-fitting mechanism 5 is arranged above the positioning mechanism 4; The positioning mechanism 4 includes a first cylinder 41. A first hydraulic rod 42 is installed on the first cylinder 41. The output end of the first hydraulic rod 42 penetrates through the fixed block 2 and extends into the interior of the groove 3. A guide post 43 is sleeved outside the first hydraulic rod 42. One end of the guide post 43 is fixedly installed with a support disc 44. The support disc 44 is fixedly installed in the groove 3 through a reinforcing rod. A number of uniformly distributed first sliding holes 45 and a number of uniformly distributed second sliding holes 46 are formed in the guide post 43. Outer support assemblies 47 are arranged inside the first sliding holes 45 and the second sliding holes 46. A first oil-impregnated bearing workpiece 6 and a second oil-impregnated bearing workpiece 7 are respectively sleeved outside the two outer support assemblies 47. A workpiece 8 with an oil-impregnated bearing to be press-fitted is arranged between the first oil-impregnated bearing workpiece 6 and the second oil-impregnated bearing workpiece 7. A clamping assembly 48 is arranged outside the workpiece 8 with an oil-impregnated bearing to be press-fitted. The clamping assembly 48 is connected to the first hydraulic rod 42. The second oil-impregnated bearing workpiece 7, the workpiece 8 with an oil-impregnated bearing to be press-fitted, and the first oil-impregnated bearing workpiece 6 are sequentially placed on the guide post 43. At this time, the first cylinder 41 in the positioning mechanism 4 is started to drive the first hydraulic rod 42 to move downward. The first hydraulic rod 42 is kept stable under the guidance of the guide post 43. The support disc 44 at one end of the guide post 43 is used to support the workpiece, and its stability is ensured through the reinforcing rod. When the first hydraulic rod 42 moves downward, the outer support assemblies 47 in the first sliding holes 45 and the second sliding holes 46 outside the guide post 43 extend out synchronously, and respectively tighten the first oil-impregnated bearing workpiece 6 and the second oil-impregnated bearing workpiece 7 from the inside, so that they are fixed in the groove 3. At the same time, when the outer support assemblies 47 tighten the first oil-impregnated bearing workpiece 6 and the second oil-impregnated bearing workpiece 7, the clamping assembly 48 connected to the first hydraulic rod 42 just clamps the workpiece 8 with an oil-impregnated bearing to be press-fitted from the outside, and positions it between the first oil-impregnated bearing workpiece 6 and the second oil-impregnated bearing workpiece 7, ensuring that the three workpieces are in a coaxial state. After positioning is completed, the press-fitting mechanism 5 is started, and it performs a press-fitting operation on the first oil-impregnated bearing workpiece 6, the second oil-impregnated bearing workpiece 7, and the workpiece 8 with an oil-impregnated bearing to be press-fitted. Since the positioning mechanism 4 has accurately fixed the positions of the workpieces, the first oil-impregnated bearing workpiece 6 and the second oil-impregnated bearing workpiece 7 can be accurately embedded into the workpiece 8 with an oil-impregnated bearing to be press-fitted during the press-fitting process, thereby effectively avoiding problems such as misalignment and offset, improving the precision and efficiency of press-fitting, ensuring the product quality after press-fitting, being applicable to batch production, reducing manual operation errors, and thus improving the production efficiency.

[0020] Further, as Figures 1-8As shown in the figure, the outer support assembly 47 includes sliding blocks 471. A plurality of sliding blocks 471 are fixedly installed on the first hydraulic rod 42. The plurality of sliding blocks 471 are respectively slidably disposed inside the first sliding hole 45 and the second sliding hole 46. A first connecting rod 472 is hinged on the sliding block 471. One end of the first connecting rod 472 away from the sliding block 471 is hinged with an arc-shaped support block 473. A plurality of arc-shaped support blocks 473 respectively abut against the inner side walls of the first oil-impregnated bearing workpiece 6 and the second oil-impregnated bearing workpiece 7. The clamping assembly 48 includes a connecting plate 481. The connecting plate 481 is fixedly installed on the first hydraulic rod 42. The connecting plate 481 is disposed below the support plate 44. A plurality of uniformly distributed second connecting rods 482 are hinged on the connecting plate 481. One end of the second connecting rod 482 away from the connecting plate 481 is hinged with an L-shaped clamping rod 483. A plurality of uniformly distributed sliding grooves 9 are formed in the fixed block 2. The L-shaped clamping rod 483 is slidably disposed inside the sliding groove 9. An arc-shaped clamping block 484 is installed on the L-shaped clamping rod 483. A plurality of arc-shaped clamping blocks 484 abut against the outer side wall of the workpiece 8 with the oil-impregnated bearing to be press-fitted. When the first cylinder 41 drives the first hydraulic rod 42 to move, the plurality of sliding blocks 471 installed on the first hydraulic rod 42 respectively slide inside the first sliding hole 45 and the second sliding hole 46 of the guide post 43. As the sliding block 471 moves, the first connecting rod 472 hinged thereto pushes the arc-shaped support block 473 to expand outwards, so that a plurality of arc-shaped support blocks 473 respectively abut against the inner side walls of the first oil-impregnated bearing workpiece 6 and the second oil-impregnated bearing workpiece 7, thereby realizing the stable positioning of these two oil-impregnated bearing workpieces and ensuring their accurate positions during the press-fitting process. At the same time, the connecting plate 481 installed on the first hydraulic rod 42 also moves accordingly. Since the connecting plate 481 is disposed below the support plate 44, the plurality of second connecting rods 482 hinged on the connecting plate 481 will drive the L-shaped clamping rod 483 to slide inside the sliding groove 9 of the fixed block 2. The arc-shaped clamping block 484 on the L-shaped clamping rod 483 approaches the workpiece 8 with the oil-impregnated bearing to be press-fitted as the L-shaped clamping rod 483 slides. Finally, when a plurality of arc-shaped support blocks 473 respectively abut against the inner side walls of the first oil-impregnated bearing workpiece 6 and the second oil-impregnated bearing workpiece 7, a plurality of arc-shaped clamping blocks 484 just abut against the outer side wall of the workpiece 8 with the oil-impregnated bearing to be press-fitted, clamping and fixing it tightly. After the positioning mechanism 4 positions and clamps each workpiece, the upper press-fitting mechanism 5 starts to work, applying pressure to the positioned workpiece to be press-fitted, and accurately press-fitting the first oil-impregnated bearing workpiece 6 and the second oil-impregnated bearing workpiece 7 into the predetermined positions of the workpiece 8 with the oil-impregnated bearing to be press-fitted, thereby realizing the precise positioning and reliable fixation of each workpiece during the double oil-impregnated bearing press-fitting process, ensuring the high precision and high efficiency of the press-fitting operation, and thus improving the assembly quality of the product and the stability of production.

[0021] Further, as Figures 1-8As shown in the figure, a support plate 10 is fixedly installed at the lower end of the frame 1. The first cylinder 41 is installed on the support plate 10. The support plate 10 at the lower end of the frame 1 provides an installation foundation for the first cylinder 41. By fixing the first cylinder 41, the stability during its driving of the first hydraulic rod 42 is ensured, guaranteeing the reliable operation of the positioning mechanism 4.

[0022] Further, as Figures 1-8 shown, the pressing mechanism 5 includes a second cylinder 51. The second cylinder 51 is installed on the frame 1, and a second hydraulic rod 52 is installed on the second cylinder 51. The output end of the second hydraulic rod 52 penetrates through the frame 1 and is fixedly connected to a pressing plate 53. A threaded mounting block 54 is fixedly installed at the lower end of the pressing plate 53. A pressing rod 55 is threadedly connected to the threaded mounting block 54. One end of the pressing rod 55 away from the threaded mounting block 54 is fixedly connected to a pressing head 56. The pressing head 56 corresponds to the guide post 43. A relief hole 57 is formed in the pressing rod 55, and a pressing hole 58 is formed in the pressing head 56. The pressing hole 58 is communicated with the relief hole 57. The pressing mechanism 5 further includes a pressing plate 59. Two guide rods 510 are fixedly installed on the pressing plate 59. One end of the guide rod 510 away from the pressing plate 59 penetrates through the pressing plate 53 and is fixedly connected to the frame 1. A spring 511 is sleeved on the outer side of the guide rod 510. One end of the spring 511 is connected to the pressing plate 53, and the other end of the spring 511 is connected to the pressing plate 59. A through hole 591 is formed in the pressing plate 59. The pressing head 56 movably penetrates through the through hole 591. When pressing is required, the second cylinder 51 is started to drive the second hydraulic rod 52 to extend downward. After the output end penetrates through the frame 1, it pushes the pressing plate 53 fixed thereto to move downward. The threaded mounting block 54 at the lower end of the pressing plate 53 is threadedly connected to the pressing rod 55. Thus, the pressing head 56 can be replaced according to different requirements. The pressing rod 55 moves downward together with the pressing plate 53. The pressing head 56 on the pressing rod 55 faces the guide post 43, and can accurately position at the workpiece 8 to be pressed with an oil-impregnated bearing, ensuring the accuracy of the pressing process. When the pressing head 56 passes through the through hole 591 on the pressing 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 pressed with an oil-impregnated bearing, and then the first oil-impregnated bearing workpiece 6 is subsequently pressed into the workpiece 8 to be pressed with an oil-impregnated bearing. After the pressing is completed, the second cylinder 51 drives the second hydraulic rod 52 to retract. The elastic restoring force of the spring 511 can assist the pressing plate 53 to quickly return, preparing for the next pressing. Thus, the entire pressing mechanism 5 realizes accurate, stable and safe pressing operations through the coordinated work of components such as the second cylinder 51, the second hydraulic rod 52, the pressing plate 53, the pressing rod 55, the pressing head 56 and the spring 511. Meanwhile, the relief hole 57 on the press-fitting rod 55 communicates with the press hole 58 on the press head 56 to form a through channel, providing a channel for the press-fitting operation. When the pressure plate 53 moves downward, the spring 511 sleeved on the outside is compressed during the downward movement of the pressure plate 53, providing a buffering force through elastic deformation to avoid damage caused by rigid collision between the press head 56 and the workpiece. One end of the guide rod 510 is fixed on the frame 1, and the other end penetrates through the pressure plate 53 to ensure the stability of the movement of the pressure plate 53.

[0023] Furthermore, as Figures 1-8 shown, the diameter of the relief hole 57 is larger than the outer diameter of the guide post 43, and the diameter of the relief hole 57 is smaller than the outer diameter of the first oil-impregnated bearing workpiece 6. The diameter of the press hole 58 is the same as the outer diameter of the first oil-impregnated bearing workpiece 6. The diameter of the relief hole 57 being larger than the outer diameter of the guide post 43 enables the guide post 43 to smoothly pass through the relief hole 57 during the press-fitting process, avoiding interference between the two and ensuring the smooth progress of the press-fitting action. At the same time, the diameter of the relief hole 57 being smaller than the outer diameter of the first oil-impregnated bearing workpiece 6 restricts the first oil-impregnated bearing workpiece 6 to only be in the position of the press head 56, preventing it from falling into the relief hole 57 and ensuring the accuracy of the workpiece position. And the diameter of the press hole 58 being the same as the outer diameter of the first oil-impregnated bearing workpiece 6 enables the press head 56 to closely fit the workpiece and apply uniform and stable pressure when the press-fitting starts, accurately press-fitting the first oil-impregnated bearing workpiece 6 into the workpiece 8 to be press-fitted with the oil-impregnated bearing, thus ensuring the orderly cooperation of each component during the press-fitting process and improving the accuracy and efficiency of the press-fitting.

[0024] As Figures 1-8 shown, the principle of a double oil-impregnated bearing press-fitting auxiliary device provided in this embodiment is as follows: First, place the second oil-impregnated bearing workpiece 7, the workpiece 8 to be press-fitted with an oil-impregnated bearing, and the first oil-impregnated bearing workpiece 6 on the guide post 43 in sequence. Start the first cylinder 41 in the positioning mechanism 4 to drive the first hydraulic rod 42 to move downward. A plurality of sliding blocks 471 mounted on the first hydraulic rod 42 slide in the first sliding hole 45 and the second sliding hole 46 of the guide post 43 respectively. As the sliding blocks 471 move, the first connecting rods 472 hinged thereto push the arc-shaped support blocks 473 to expand outward, so that several arc-shaped support blocks 473 respectively abut against the inner side walls of the first oil-impregnated bearing workpiece 6 and the second oil-impregnated bearing workpiece 7. At the same time, the connecting plate 481 mounted on the first hydraulic rod 42 also moves accordingly. Since the connecting plate 481 is arranged below the support plate 44, several second connecting rods 482 hinged on the connecting plate 481 will drive the L-shaped clamping rods 483 to slide in the chute 9 of the fixed block 2. The arc-shaped clamping blocks 484 on the L-shaped clamping rods 483 approach the workpiece 8 to be press-fitted with an oil-impregnated bearing as the L-shaped clamping rods 483 slide. Finally, when several arc-shaped support blocks 473 respectively abut against the inner side walls of the first oil-impregnated bearing workpiece 6 and the second oil-impregnated bearing workpiece 7, several arc-shaped clamping blocks 484 just abut against the outer side wall of the workpiece 8 to be press-fitted with an oil-impregnated bearing, positioning it between the first oil-impregnated bearing workpiece 6 and the second oil-impregnated bearing workpiece 7 to ensure that the three workpieces are in a coaxial state. After positioning is completed, start the second cylinder 51 to drive the second hydraulic rod 52 to extend downward. The output end penetrates through the frame 1 and then pushes the pressing plate 53 fixed thereto to move downward. The threaded mounting block 54 at the lower end of the pressing plate 53 is threadedly connected to the pressing rod 55, so that the pressing rod 55 moves downward together with the pressing plate 53. The pressing head 56 on the pressing rod 55 is opposite to the guide post 43. When the pressing head 56 passes through the through hole 591 on the pressing plate 59, it squeezes the first oil-impregnated bearing workpiece 6. The second oil-impregnated bearing workpiece 7 is first pressed into the workpiece 8 to be press-fitted with an oil-impregnated bearing, and then the first oil-impregnated bearing workpiece 6 is subsequently pressed into the workpiece 8 to be press-fitted with an oil-impregnated bearing. After the press-fitting is completed, the second cylinder 51 drives the second hydraulic rod 52 to retract. The elastic restoring force of the spring 511 can assist the pressing plate 53 to quickly return, preparing for the next press-fitting, thus effectively avoiding problems such as misalignment and offset, improving the precision and efficiency of the press-fitting, ensuring the product quality after the press-fitting, being suitable for mass production, reducing manual operation errors, and thus improving the production efficiency.

[0025] As used in the specification and claims, certain terms are used to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in names as a way to distinguish components, but rather use the difference in functions of components as the criterion for distinction. As used throughout the specification and claims, "comprising" is an open-ended term and should be interpreted as "including but not limited to". "Substantially" means within an acceptable error range, and those skilled in the art can solve technical problems within a certain error range and basically achieve the technical effect.
