[0024] The one-way delivery pipe 31 includes a support pipe 311 and a one-way oil inlet valve 312. The bottom of the support pipe 311 is fixedly connected to the oil extraction pipe 48, the top of the support pipe 311 is fixedly connected to the oil injection cylinder 32, and the one-way oil inlet valve 312 is fixedly connected to the top of the support pipe 311.

[0025] The one-way output pipe 36 includes a one-way oil outlet valve 361 and an oil injection pipe 362. The one-way oil outlet valve 361 is fixedly connected to the bottom end of the oil injection cylinder 32. The oil injection head 37 is fixedly connected to the one-way oil outlet valve 361. The oil injection pipe 362 is fixedly connected to the top end of the one-way oil outlet valve 361.

[0026] A cross groove is provided above the inner cavity of the placement table 51, and the anti-skid clamping plate 1 53 and the anti-skid clamping plate 2 54 are fitted in the inner cavity of the cross groove, and the top ends of the anti-skid clamping plate 1 53 and the anti-skid clamping plate 2 54 are inclined surfaces.

[0027] In this embodiment, a cylinder for driving the middle plate 22 is arranged inside the driving device 21. In the initial state, the middle plate 22 pushes the limit plate 35 upward, and the return spring 33 is in a stretched state. When used for the first time, the lubricating oil is added into the inner cavity of the storage box 41 from the adding pipe 43, and then the lubricating oil is heated by the heating rod 42. The staff pulls the anti-skid clamping plate 2 54 to drive the piston plate 46 to move in the inner cavity of the piston cylinder 45. At this time, the heated oil in the inner cavity of the storage box 41 is pumped into the inner cavity of the piston cylinder 45 through the oil extraction pipe 48 and the one-way oil inlet valve 2 49 for storage, and then the anti-skid clamping plate 1 53 is released; Next, the bearing is pressed downward along the inclined surface above the anti-skid clamping plate 1 53 and the anti-skid clamping plate 2 54. At this time, the anti-skid clamping plate 1 53 and the anti-skid clamping plate 2 54 are driven by the bearing to move in the direction of the clamping spring 52, thereby causing the clamping spring 52 to contract, generating a thrust on the anti-skid clamping plate 1 53 and the anti-skid clamping plate 2 54, thereby clamping the bearing by the anti-skid clamping plate 1 53 and the anti-skid clamping plate 2 54. Next, the shaft is placed on the bearing, thereby realizing the elasticity of the clamping spring 52, driving the anti-skid clamping plate 1 53 and the anti-skid clamping plate 2 54 to limit and fix bearings of different models. At this time, the oil spray head 37 is located on the side of the contact between the bearing and the shaft; When the anti-skid clamping plate 1 53 moves, it drives the piston plate 46 to move in the inner cavity of the piston cylinder 45. When the bearing is larger, the anti-skid clamping plate 1 53 moves more, and at this time, the piston plate 46 moves a longer distance in the inner cavity of the piston cylinder 45. The piston plate 46 delivers the lubricating oil in the inner cavity of the piston cylinder 45 along the telescopic tube 47 and the one-way delivery pipe 31 through the one-way oil outlet valve 2 491 and the one-way oil inlet valve 1 312 to the inner cavity of the oil injection cylinder 32. Due to the setting of the air vent 321, the inner cavity of the air vent 321 is at normal pressure, which will not cause the lubricating oil to be unable to enter. The piston shaft 34 is moved downwards and the lubricating oil in the inner cavity of the oil injection cylinder 32 is prevented from flowing back into the inner cavity of the one-way delivery pipe 31 by the one-way oil inlet valve 131. The lubricating oil in the inner cavity of the oil injection cylinder 32 can only be delivered to the oil injection head 37 through the one-way delivery pipe 36, and then sprayed to the contact point between the bearing and the shaft through the oil injection head 37, thereby realizing the use of hot lubricating oil with high fluidity to spray the contact point between the bearing and the shaft, thereby avoiding the wear of the contact point between the bearing and the shaft due to the close fit during press-fitting, making it more convenient to press-fit the bearing and the shaft, and no longer requiring subsequent lubrication of the bearing and the shaft, thereby improving the overall processing efficiency. Furthermore, when the anti-skid clamping plate 1 53 and the anti-skid clamping plate 2 54 are used to limit and fix bearings of different types, the distances of displacement of the piston plate 46 in the inner cavity of the piston cylinder 45 are also different, thereby achieving the goal of determining the amount of lubricating oil required according to the size of the bearing, avoiding the waste of too much lubricating oil when facing a smaller bearing, and avoiding the situation of too little lubricating oil when facing a larger bearing; When the oil injection is finished, the middle plate 22 drives the press-fitting column 23 to continue to move downward along the piston shaft 34 .

[0028] Embodiment 2:

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, an embodiment of the present invention provides a servo motor bearing press, the vibration mechanism 6 includes a spring assembly 61, the spring assembly 61 is fixedly connected at the bottom of the middle part of the inner cavity of the support frame 1, the top of the spring assembly 61 is fixedly connected to the placement table 51, the bottom end of the middle plate 22 is fixedly connected to a rubber cone block rod 63, the side of the placement table 51 close to the rubber cone block rod 63 is fixedly connected to a vibration block 62, and the vibration block 62 is located on the moving path of the rubber cone block rod 63.

[0030] The spring assembly 61 is composed of a damping telescopic rod 611 and a vibration spring 612 . The damping telescopic rod 611 is located at the center of the inner cavity of the vibration spring 612 .

[0031] In this embodiment, when the press-fitting column 23 moves downward, the rubber cone block rod 63 is driven to move downward. At this time, through the elasticity of the spring assembly 61, the vibration block 62 and the rubber cone block rod 63 are in contact, thereby driving the placement table 51 to vibrate. When the placement table 51 vibrates, the bearing is driven to vibrate, so that the lubricating oil can be evenly distributed at the contact point between the bearing and the shaft. Then the press-fitting column 23 presses the bearing and the shaft. After the press-fitting is completed, the staff takes out the workpiece. At this time, the clamping spring 52 drives the anti-skid clamping plate 1 53 and the anti-skid clamping plate 2 54 to reset. When the anti-skid clamping plate 1 53 is reset, it drives the piston plate 46 to reset in the inner cavity of the piston cylinder 45. At this time, the lubricating oil in the inner cavity of the storage box 41 is extracted through the oil extraction pipe 48 and the one-way oil inlet valve 2 49 to replenish the inner cavity of the piston cylinder 45 for subsequent use.

[0032] Working principle and use process: In the initial state, the middle plate 22 pushes the limit plate 35 upward, and the return spring 33 is in a stretched state; When used for the first time, the lubricating oil is added into the inner cavity of the storage box 41 from the adding pipe 43, and then the lubricating oil is heated by the heating rod 42. The staff pulls the anti-skid clamping plate 1 53 to drive the piston plate 46 to move in the inner cavity of the piston cylinder 45 in the direction of the clamping spring 52, and then releases the anti-skid clamping plate 1 53. At this time, the elasticity of the clamping spring 52 drives the piston plate 46 to reset, and then the heated oil in the inner cavity of the storage box 41 is pumped into the inner cavity of the piston cylinder 45 through the oil extraction pipe 48 and the one-way oil inlet valve 2 49 for storage; Next, the bearing is placed between the anti-skid clamping plate 1 53 and the anti-skid clamping plate 2 54 along the inclined surface above the anti-skid clamping plate 1 53 and the anti-skid clamping plate 2 54 from the top of the placement table 51 downwards. The workpiece presses the anti-skid clamping plate 1 53 and the anti-skid clamping plate 2 54 toward the damping ring 56. At this time, the elasticity of the clamping spring 52 drives the anti-skid clamping plate 1 53 and the anti-skid clamping plate 2 54 to clamp bearings of different sizes. Then, the shaft is placed inside the bearing. When the anti-slip clamping plate 1 53 moves, it drives the piston plate 46 to move in the inner cavity of the piston cylinder 45 toward the direction of the telescopic tube 47, so that the hot lubricating oil in the inner cavity of the piston cylinder 45 is squeezed and transported to the one-way delivery pipe 31 along the telescopic tube 47, and enters the inner cavity of the oil injection cylinder 32 after passing through the one-way oil outlet valve 2 491. The larger the workpiece, the larger the amplitude of the piston plate 46 in the inner cavity of the piston cylinder 45, and the more lubricating oil enters the inner cavity of the oil injection cylinder 32. Then the driving device 21 drives the middle plate 22 and the press-fitting column 23 to descend. At this time, the return spring 33 contracts, driving the bottom of the piston shaft 34 to descend in the inner cavity of the oil injection cylinder 32. At this time, due to the presence of the one-way oil inlet valve 312 and the oil injection pipe 362, the lubricating oil in the inner cavity of the oil injection cylinder 32 can only enter the inner cavity of the one-way oil outlet valve 361 after being squeezed, and the lubricating oil is sprayed to the contact point between the bearing and the shaft through the oil injection head 37, so as to heat and lubricate the contact point between the bearing and the shaft. Then, when the press-fitting column 23 moves downward, it also drives the rubber cone block rod 63 downward. Through the fit between the rubber cone block rod 63 and the vibration block 62 and the elasticity of the spring assembly 61 at the bottom of the placement table 51, the rubber cone block rod 63 drives the placement table 51 to vibrate when it moves downward, thereby driving the bearing and the shaft to vibrate, and then evenly applying the lubricating oil to the contact point between the bearing and the shaft; Then the press-fitting column 23 presses the bearing and the shaft. After the press-fitting is completed, the workpiece is taken out from between the anti-slip clamping plate 1 53 and the anti-slip clamping plate 2 54. At this time, the elasticity of the clamping spring 52 drives the anti-slip clamping plate 1 53 and the anti-slip clamping plate 2 54 to reset, and then drives the piston plate 46 to reset in the inner cavity of the piston cylinder 45, so that the lubricating oil in the inner cavity of the storage box 41 is replenished into the inner cavity of the piston cylinder 45 for next use.
