Description

TECHNICAL FIELD

[0001] The application relates to the technical field of oil injection devices, in particular to an automatic oil injection device for single-rod bearings. BACKGROUND

[0002] A bearing is an important part in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient in the movement process, and ensure the rotation accuracy. In the bearing production process, oil injection is a very important process operation. Oil injection can provide sufficient lubrication for the bearing, reduce friction and wear, reduce noise and temperature during bearing operation, and prolong the service life of the bearing.

[0003] As shown in the single-rod bearing shown in Figure 1 The single-rod bearing includes a rod body 100, a ball 200, and a shaft sleeve 300. The rod body is cylindrical, the shaft sleeve is installed on the outer surface of the rod body, and is coaxially arranged with the rod body. The shaft sleeve is rotatably connected to the rod body, and can also produce a certain displacement along the axial direction of the rod body. The ball is arranged between the rod body and the shaft sleeve, and is spaced apart along the circumferential direction of the rod body. When oil is injected, lubricating oil needs to be injected between the shaft sleeve and the rod body.

[0004] For the related technology in the above, the current oil injection operation is often manually performed. Due to the close fit between the rod body and the shaft sleeve, it is difficult to make the lubricating oil evenly distributed, and the labor intensity of personnel is large, and thus needs to be improved. CONTENT OF THE UTILITY MODEL

[0005] In order to facilitate oil injection of the single-rod bearing, the application provides an automatic oil injection device for the single-rod bearing.

[0006] The automatic oil injection device for the single-rod bearing provided by the application adopts the following technical scheme:

[0007] An automatic oil injection device for a single-rod bearing includes a support seat, a driving member, a positioning block, an oil injection pipe, a driving motor, and a rotating disc. The support seat is used for placing the single-rod bearing. The positioning block is arranged above the support seat and is used for pressing the rod body. The driving member is connected to the positioning block and is used for controlling the lifting of the positioning block.

[0008] The oil injection pipe is arranged on the positioning block, and the oil outlet of the oil injection pipe faces the support surface of the support seat and is used for injecting oil between the rod body and the shaft sleeve.

[0009] The rotating disc is rotatably arranged on one side of the support seat, and is used for controlling the rotation of the shaft sleeve. The driving motor is connected to the rotating disc and is used for controlling the rotation of the rotating disc.

[0010] By adopting the above technical solution, when the single rod bearing needs to be lubricated, the worker first places the single rod bearing on the support seat, and then uses the drive component to control the positioning block to move and abut against the rod body, thereby fixing the single rod bearing.

[0011] Then, the lubricating oil in the oil injection pipe is squeezed between the rod and the bushing under pressure. At the same time, the drive motor is activated, which controls the rotating disk to rotate. Since the rotating disk and the bushing are tangent, the bushing rotates due to static friction, and the bushing and the rod rotate relative to each other. The circumferential rotation of the bushing disperses the lubricating oil, making it evenly distributed on the balls.

[0012] Preferably, the driving component is a pneumatic cylinder or an electric push rod.

[0013] By adopting the above technical solution, the pneumatic cylinder or electric push rod can realize the up and down movement of the positioning block, while generating a continuous, stable and reliable clamping force to achieve the clamping of the positioning block on the rod body.

[0014] Preferably, it further includes a conveyor belt and a transfer assembly, the conveyor belt being used to transport the single-bar bearing and located on one side of the support, and the transfer assembly being used to transfer the single-bar bearing on the conveyor belt to below the positioning block.

[0015] By adopting the above technical solution, the single-bar bearing is gradually conveyed by the conveyor belt and approaches the support seat. Then, the transfer assembly is used to transfer the single-bar bearing from the conveyor belt to directly below the positioning block for oil injection.

[0016] Preferably, the transfer assembly includes a first cylinder, a slide block, a second cylinder, and a limiting plate. The slide block is horizontally movable. The first cylinder is connected to the slide block and is used to control the movement of the slide block. The second cylinder is disposed on the slide block. The limiting plate is connected to the piston rod of the second cylinder. The second cylinder is used to control the horizontal movement of the limiting plate. A limiting hole is provided on the limiting plate for a single rod bearing to be engaged.

[0017] By adopting the above technical solution, when material needs to be transferred, the second cylinder is first used to control the limiting plate to gradually approach the single rod bearing, so that the single rod bearing is in the limiting hole. Then, the first cylinder is operated to control the slide to move horizontally, thereby driving the entire limiting plate and the single rod bearing to move horizontally, so as to gradually move the single rod bearing to directly below the positioning block.

[0018] Preferably, a positioning sensor is provided at one end of the conveyor belt near the support base.

[0019] By adopting the above technical solution, during the process of conveying the single-bar bearing, the positioning sensor can detect whether the single-bar bearing is in position. When the single-bar bearing reaches the preset position, the conveyor belt will stop conveying so that the transfer component can transfer the single-bar bearing.

[0020] Preferably, it further includes a lifting block and a supporting block. The lifting block is lifted and lowered on the support base and is used to support the rod body. The supporting blocks are located on both sides of the lifting block. The horizontal distance between the two supporting blocks is greater than the diameter of the rod body and less than the diameter of the bushing. The two supporting blocks are used to support the bushing.

[0021] By adopting the above technical solution, after the single-rod bearing is placed on the lifting block, the drive component controls the positioning block to press against the rod body. The lifting block, under pressure, will move vertically downwards, thereby causing the rod body to move downwards. Since the bushing is supported by the two support blocks, it will not move downwards with the rod body. At this time, the rod body and bushing will undergo relative displacement. The gap between the rod body and bushing increases, and then oil is injected, allowing the lubricating oil to flow to the inner wall of the bushing and the outer wall of the rod body.

[0022] Preferably, the lifting block is also provided with an oil injection port, which is located below the positioning block and is used for oil injection.

[0023] By adopting the above technical solution, lubricating oil can also be injected onto the balls from bottom to top through the oil injection port, which plays an auxiliary role in oil injection and improves the fullness of oil injection into the single rod bearing.

[0024] Preferably, the support base is provided with a groove for accommodating the lifting block, and the lifting block is connected to the support base by a spring.

[0025] By adopting the above technical solution, when the lifting block is subjected to the vertical downward pressure of the positioning block, the spring is compressed, causing the lifting block to move downward. When the pressure of the positioning block is removed, the elastic force of the spring can drive the lifting block to return to its original position.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] (1) By setting up a drive unit, positioning block, oil injection pipe, drive motor, and rotating disk, when lubricating a single rod bearing, the operator first places the single rod bearing on the support seat. Then, the positioning block is moved by the drive unit to make it tightly abut against the rod body, thereby achieving a stable fixation of the single rod bearing. Subsequently, the lubricating oil in the oil injection pipe is squeezed into the gap between the rod body and the bushing under pressure. At the same time, the drive motor is started, and the drive motor causes the rotating disk to rotate. Since the rotating disk and the bushing are tangent, the bushing rotates synchronously by means of static friction, which causes the bushing and the rod body to rotate relative to each other. The circumferential rotation of the bushing can effectively disperse the lubricating oil, so that the lubricating oil is evenly covered on the balls.

[0028] (2) By setting up a conveyor belt and a transfer assembly, the transfer assembly can transfer the single rod bearing on the conveyor belt to the bottom of the positioning block. Attached Figure Description

For example, they can refer to a fixed connection; a detachable connection; an integral part; or a mechanical connection. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0038] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Without conflict, those skilled in the art can combine and integrate the different embodiments or examples shown in this application, as well as the features of those embodiments or examples.

[0039] This application discloses an automatic oil filling device for a single-bar bearing. (Refer to...) Figure 2 and Figure 3 The automatic oil filling device includes a support base 1, a drive component 2, a positioning block 3, an oil filling pipe 4, a drive motor 5, and a rotating disk 6. The support base 1 serves as a carrier for placing the single-rod bearing. The positioning block 3 is raised and lowered above the support base 1 and is used to press the rod body. The drive component 2 is connected to the positioning block 3 and is used to control the raising and lowering of the positioning block 3 and to provide continuous pressing force to the positioning block 3. The drive component 2 is a pneumatic cylinder or an electric push rod; in this embodiment, the drive component 2 is a pneumatic cylinder, and the piston rod of the pneumatic cylinder is connected to the positioning block 3.

[0040] Oil injection pipe 4 is installed on positioning block 3. One end of oil injection pipe 4 is an oil inlet, and the other end is an oil outlet. The oil inlet of oil injection pipe 4 is connected to an external oil tank, and the oil outlet of oil injection pipe 4 faces the support surface of support base 1 and is used to inject oil between the rod body and the bushing. Rotary disk 6 is rotatably connected to one side of support base 1. The rotation axis of rotary disk 6 is vertical. Rotary disk 6 is tangent to the bushing of single rod bearing and is used to control the rotation of bushing. The output shaft of drive motor 5 is connected to rotary disk 6 and is used to control the rotation of rotary disk 6.

[0041] When lubrication of the single-bar bearing is required, the operator first places the single-bar bearing on the support base 1. Then, the drive component 2 controls the positioning block 3 to move and abut against the rod body, thereby fixing the single-bar bearing. Next, the lubricating oil in the oil injection pipe 4 is forced between the rod body and the bushing under pressure. Simultaneously, the drive motor 5 is activated, controlling the rotating disk 6 to rotate. Since the rotating disk 6 is tangent to the bushing, the bushing rotates due to static friction, causing relative rotation between the bushing and the rod body. The circumferential rotation of the bushing disperses the lubricating oil, ensuring its even distribution on the balls.

[0042] Combination Figure 4 Specifically, the support base 1 is also equipped with a lifting block 7 and a supporting block 8. The lifting block 7 is located directly below the positioning block 3. The lifting block 7 is raised and lowered on the support base 1 and is used to support the rod body. The support base 1 has a groove for accommodating the lifting block 7. A spring is installed in the groove and is located below the support base 1. The lifting block 7 is connected to the support base 1 through the spring. The supporting blocks 8 are fixedly connected to both sides of the lifting block 7. The horizontal distance between the two supporting blocks 8 is greater than the diameter of the rod body and less than the diameter of the bushing. The two supporting blocks 8 are used to support the bushing. The lifting block 7 has an oil inlet 9. An external oil tank is connected to the oil inlet 9 through a hose. The oil inlet 9 is located below the positioning block 3 and is used to inject oil into the lower part of the single rod bearing.

[0043] After the single-rod bearing is placed on the lifting block 7, the drive component 2 controls the positioning block 3 to press against the rod body. The lifting block 7, under pressure, moves vertically downwards, thereby causing the rod body to move downwards. Due to the relatively large outer diameter of the bushing, the bushing, supported by the two support blocks 8, will not move downwards with the rod body. At this time, the rod body and bushing will experience relative displacement. The gap between the rod body and bushing increases, and then oil is injected, allowing the lubricating oil to flow to the inner wall of the bushing and the outer wall of the rod body. During oil injection, oil can be injected from top to bottom through the oil injection pipe 4, and lubricating oil can also be injected onto the balls from bottom to top through the oil injection port 9, which assists in oil injection and improves the adequacy of oil injection for the single-rod bearing.

[0044] In some embodiments, a conveyor belt 10 and a transfer assembly 11 are also installed on one side of the support base 1. The conveyor belt 10 is used to transport the single-rod bearing, and the transfer assembly 11 is used to transfer the single-rod bearing on the conveyor belt 10 to directly below the positioning block 3. The transfer assembly 11 includes a first cylinder 111, a slide 112, a second cylinder 113, and a limiting plate 114. The slide 112 is horizontally movable. The first cylinder 111 is connected to the slide 112 and is used to control the movement of the slide 112. The second cylinder 113 is installed on the slide 112, and the limiting plate 114 is connected to the piston rod of the second cylinder 113. The second cylinder 113 is used to control the horizontal movement of the limiting plate 114. The limiting plate 114 has an arc-shaped limiting hole for the single-rod bearing to be inserted.

[0045] When material needs to be transferred, the second cylinder 113 is used to control the limiting plate 114 to gradually approach the single rod bearing, so that the single rod bearing is in the limiting hole. Then, the first cylinder 111 is run to control the slide 112 to move horizontally, thereby driving the entire limiting plate 114 and the single rod bearing to move horizontally, so that the single rod bearing is gradually moved to the position block 3 directly below, and then oil is injected.

[0046] A positioning sensor 12 is installed at one end of the conveyor belt 10 near the support base 1. The positioning sensor 12 is used to determine the position of the single-bar bearing. During the process of conveying the single-bar bearing, the positioning sensor 12 can detect whether the single-bar bearing is in position. When the single-bar bearing reaches the preset position, the conveyor belt 10 will stop conveying so that the transfer assembly 11 can transfer the single-bar bearing.

[0047] The implementation principle of the automatic oil filling device for a single-bar bearing according to this application embodiment is as follows: When lubricating the single-bar bearing, the operator first places the single-bar bearing on the support base 1. Then, the positioning block 3 is moved by the drive component 2 to make it tightly abut against the rod body, thereby achieving a stable fixation of the single-bar bearing. Subsequently, the lubricating oil in the oil filling pipe 4 is squeezed into the gap between the rod body and the bushing under pressure. At the same time, the drive motor 5 is started, and the drive motor 5 causes the rotating disk 6 to rotate. Since the rotating disk 6 is tangential to the bushing, the bushing rotates synchronously due to the action of static friction, thereby causing relative rotation between the bushing and the rod body. The circumferential rotation of the bushing can effectively disperse the lubricating oil, so that the lubricating oil evenly covers the balls.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
