Description

Technical Field

[0001] This invention relates to the field of bearing processing technology, and specifically to an automatic bearing oiling machine. Background Technology

[0002] An automatic bearing grease injection machine is a device that injects grease into the inside of a bearing. Grease can lubricate the bearing, reduce friction during bearing rotation, and extend the bearing's service life. If lubricating oil is not injected into the bearing in time, the interval between grease injections will be too long, resulting in insufficient lubrication, excessive wear of the bearing, and reduced bearing life. Therefore, it is necessary to lubricate the bearing.

[0003] Currently, automatic bearing grease injection machines still require manual operation to inject grease into the bearing. However, manual operation usually relies on experience to control the amount of grease injected. To ensure sufficient grease enters the bearing, grease must overflow, which wastes grease and increases the cost of grease injection. Summary of the Invention

[0004] To overcome the aforementioned technical problems, the present invention aims to provide an automatic bearing grease injector. This addresses the issue that in existing technologies, grease is manually injected into the bearing using an automatic grease injector. However, manual grease injection typically relies on experience to control the amount of grease injected. To ensure sufficient grease enters the bearing, it is necessary to allow grease to overflow, which wastes grease and increases the cost of grease injection.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] An automatic bearing oiling machine includes a base, a hydraulic cylinder mounted on one side of the top surface of the base, a moving track mounted on the top surface of the base, an oiling mechanism at the bottom end of the hydraulic cylinder, the output end of the hydraulic cylinder being fixedly connected to the bottom surface of the oiling mechanism, a bearing placement plate movably mounted inside the moving track, the top surface of the bearing placement plate being used to place bearings, and a sealing mechanism at the bottom of the bearing placement plate, the sealing mechanism cooperating with the oiling mechanism and the bearing placement plate to seal the bearings.

[0007] As a further aspect of the present invention: the oil injection mechanism includes an oil injection pan, the top of the oil injection pan is provided with a conveying groove, the top surface of the conveying groove is fixedly connected to an oil storage tank, an air pump and an air pump are provided at the middle position of the top surface of the oil injection pan, and the conveying groove is connected to the oil storage tank to ensure that the grease in the oil storage tank can enter the conveying groove and to ensure that the grease in the conveying groove can be continuously supplied.

[0008] As a further aspect of the present invention: a plurality of cylindrical pressure blocks are fixedly connected to the bottom surface of the oil injection pan. The plurality of cylindrical pressure blocks are arranged in an arc shape at equal intervals on the bottom surface of the oil injection pan. A sealing top ring is fixedly connected to the bottom surface of the cylindrical pressure blocks. An oil injection groove is opened on the bottom surface of the sealing top ring. The oil injection groove is connected to the conveying groove through an oil pipe. Since the air pump is connected to the air delivery groove through an air pipe, the bearing placement plate can be used in conjunction with the oil injection mechanism to seal the top of the bearing first. Then the air pump can be turned on, and the air pump blows air into the bearing through the air delivery groove to remove dust from the inner cavity of the bearing, ensuring that the inside of the bearing is in a dust-free state, thus achieving the cleaning of the bearing.

[0009] As a further aspect of the present invention: the bottom surface of the sealing top ring is provided with an air supply groove, and the air supply groove is connected to an air pump and an air extraction pump through an air pipe.

[0010] As a further aspect of the present invention: the bearing placement plate includes a placement tray, and track sliders are fixedly connected to both sides of the placement tray. The track sliders are engaged with the moving track. Through the cooperation of the track sliders and the moving track, the placement tray can move freely along the track direction on the side of the moving track, ensuring that the bearing can be removed from the bottom surface of the oiling mechanism after oiling, which facilitates the replacement of the bearing on the bearing placement plate.

[0011] As a further aspect of the present invention: the top surface of the placement tray is provided with a plurality of limiting grooves, and the plurality of limiting grooves correspond one-to-one with a plurality of cylindrical pressing blocks. In this way, after the bearing is placed in the limiting groove, the cylindrical pressing blocks can be pressed on the top surface of the limiting groove. Since the plurality of limiting grooves correspond one-to-one with the plurality of cylindrical pressing blocks, the cylindrical pressing blocks can seal the top surface of the bearing by cooperating with the bearing through the sealing top ring.

[0012] As a further aspect of the present invention: the sealing mechanism includes a support plate, a hydraulic push rod is provided at the top edge of the support plate, a plurality of cylindrical support blocks are fixedly connected to the top surface of the support plate, and a sealing bottom ring is fixedly connected to the top surface of the cylindrical support blocks. The plurality of cylindrical support blocks correspond one-to-one with a plurality of limiting grooves. When the interior of the bearing is in a dust-free state, the support plate can be moved upward by the hydraulic push rod, causing the cylindrical support blocks on the support plate to support the bottom surface of the bearing. The sealing bottom ring on the bottom surface of the cylindrical support blocks can cooperate with the bearing to seal the bottom surface of the bearing. Therefore, after cooperating with the sealing top ring, it can... A sealed cavity is formed inside the bearing. Then, the air pump can be turned on. Since the air pump is connected to the air delivery channel through the air pipe, it can evacuate the air inside the bearing, creating a negative pressure environment inside the bearing. An electromagnetic latch is installed at the port of the air delivery channel. Once a negative pressure environment is created inside the bearing, the electromagnetic latch can be closed. An electromagnetic latch is also installed at the port of the oil filling channel. At this time, the electromagnetic latch at the port of the oil filling channel can be opened. Since a negative pressure environment is created inside the bearing, the grease in the delivery channel can enter the inside of the bearing through the oil pipe, thus realizing the oil filling of the bearing.

[0013] The beneficial effects of this invention are as follows: The bearing is placed on the top surface of the bearing placement plate, and then the bearing placement plate can seal the bearing placed on the top surface of the placement plate through the oil injection mechanism and the sealing mechanism. The oil injection mechanism can evacuate the air in the sealed cavity of the bearing, so that the internal environment of the bearing is negative pressure. Then, grease is injected into the bearing through the oil injection mechanism, which can ensure that the bearing is full of grease, improve the oil injection effect of the bearing, and since the bearing placement plate seals the bearing through the oil injection mechanism and the sealing mechanism, it will limit the amount of grease injected, thus saving materials by preventing the amount of grease injected from being too much or too little.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1-6 As shown, an automatic bearing oiling machine includes a base 1, a hydraulic cylinder 11 installed on one side of the top surface of the base 1, a moving track 2 installed on the top surface of the base 1, an oiling mechanism 3 provided at the bottom end of the hydraulic cylinder 11, the output end of the hydraulic cylinder 11 being fixedly connected to the bottom surface of the oiling mechanism 3, a bearing placement plate 4 movably arranged inside the moving track 2, the top surface of the bearing placement plate 4 being used to place bearings, and a sealing mechanism 5 provided at the bottom of the bearing placement plate 4, the sealing mechanism 5 cooperating with the oiling mechanism 3 and the bearing placement plate 4 to seal the bearings;

[0024] During operation, the bearing can be placed on the top surface of the bearing mounting plate 4. The bearing mounting plate 4 can then seal the bearing placed on the top surface of the bearing mounting plate 4 through the oil injection mechanism 3 and the sealing mechanism 5. The oil injection mechanism 3 can evacuate the air in the sealed cavity of the bearing, creating a negative pressure environment inside the bearing. Then, grease is injected into the bearing through the oil injection mechanism 3, which can ensure that the bearing is full of grease, improving the oil injection effect of the bearing. Furthermore, since the bearing mounting plate 4 seals the bearing through the oil injection mechanism 3 and the sealing mechanism 5, it will limit the amount of grease injected, thus saving materials by preventing the amount of grease injected from being too much or too little.

[0025] like Figure 3 As shown, the oiling mechanism 3 includes an oiling pan 31, a conveying trough 32 on the top of the oiling pan 31, an oil storage tank 33 fixedly connected to the top surface of the conveying trough 32, an air pump 34 and an air pump 35 at the middle position of the top surface of the oiling pan 31, and the conveying trough 32 is connected to the oil storage tank 33 to ensure that the grease in the oil storage tank 33 can enter the conveying trough 32 and to ensure that the grease in the conveying trough 32 can be continuously supplied.

[0026] like Figure 4 As shown, a number of cylindrical pressure blocks 36 are fixedly connected to the bottom surface of the oil filling pan 31. The cylindrical pressure blocks 36 are arranged in an arc shape at equal intervals on the bottom surface of the oil filling pan 31. A sealing top ring 37 is fixedly connected to the bottom surface of the cylindrical pressure blocks 36. An oil filling groove 38 is opened on the bottom surface of the sealing top ring 37. The oil filling groove 38 is connected to the conveying groove 32 through an oil pipe. An air conveying groove 39 is opened on the bottom surface of the sealing top ring 37. The air conveying groove 39 is connected to the air pump 34 and the air pump 35 through an air pipe.

[0027] During operation, since the air pump 34 is connected to the air delivery channel 39 through the air pipe, the bearing placement plate 4 can be used in conjunction with the oil injection mechanism 3 to seal the top of the bearing. Then the air pump 34 can be turned on, and the air pump 34 blows air into the bearing through the air delivery channel 39 to remove dust from the inner cavity of the bearing, ensuring that the inside of the bearing is in a dust-free state, thus achieving the cleaning of the bearing.

[0028] like Figure 5 As shown, the bearing placement plate 4 includes a placement tray 41. Track sliders 42 are fixedly connected to both sides of the placement tray 41. The track sliders 42 are engaged with the moving track 2. Through the cooperation of the track sliders 42 and the moving track 2, the placement tray 41 can move freely along the track direction on the side of the moving track 2, ensuring that the bearing can be removed from the bottom surface of the oiling mechanism 3 after oiling, which facilitates the replacement of the bearing on the bearing placement plate 4.

[0029] The top surface of the placement plate 41 is provided with several limiting grooves 43, and each limiting groove 43 corresponds to a certain number of cylindrical pressing blocks 36. After the bearing is placed in the limiting groove 43, the cylindrical pressing blocks 36 can be pressed on the top surface of the limiting groove 43. Since the limiting grooves 43 correspond to the cylindrical pressing blocks 36, the cylindrical pressing blocks 36 can seal the top surface of the bearing by cooperating with the bearing through the sealing top ring 37.

[0030] like Figure 6 As shown, the sealing mechanism 5 includes a support plate 51, a hydraulic push rod 52 is provided at the top edge of the support plate 51, a number of cylindrical support blocks 53 are fixedly connected to the top surface of the support plate 51, a sealing bottom ring 54 is fixedly connected to the top surface of the cylindrical support blocks 53, and the number of cylindrical support blocks 53 corresponds one-to-one with a number of limiting grooves 43.

[0031] Once the bearing is clean inside, the hydraulic push rod 52 can be used to move the support plate 51 upwards, allowing the cylindrical support block 53 on the support plate 51 to support the bottom surface of the bearing. The sealing bottom ring 54 on the bottom surface of the cylindrical support block 53 can cooperate with the bearing to seal the bottom surface of the bearing. Therefore, after cooperating with the sealing top ring 37, a sealed cavity can be formed inside the bearing. Then, the vacuum pump 35 can be turned on. Since the vacuum pump 35 is connected to the air delivery groove 39 through the air pipe, the vacuum pump 35 can evacuate the air inside the bearing through the air pipe and the air delivery groove 39, creating a negative pressure environment inside the bearing. An electromagnetic latch is set at the port of the air delivery groove 39. When a negative pressure environment is formed inside the bearing, the electromagnetic latch can be closed. An electromagnetic latch is also set at the port of the oil filling groove 38. At this time, the electromagnetic latch at the port of the oil filling groove 38 can be opened. Since a negative pressure environment is formed inside the bearing, the grease in the delivery groove 32 can enter the inside of the bearing through the oil pipe, realizing the oil filling of the bearing.

[0032] The working principle of this invention is as follows: First, the bearing is placed on the top surface of the bearing placement plate 4. The bearing placement plate 4, in conjunction with the oil injection mechanism 3, seals the top of the bearing. Since the air pump 34 is connected to the air delivery channel 39 through an air pipe, the air pump 34 can be turned on. The air pump 34 blows air into the bearing through the air delivery channel 39 to remove dust from the bearing's inner cavity, ensuring that the bearing's interior is dust-free. This achieves the cleaning of the bearing. Once the bearing's interior is dust-free, the hydraulic push rod 52 can be used to move the support plate 51 upwards, causing the cylindrical support block 53 on the support plate 51 to support the bottom surface of the bearing. The sealing ring 54 on the bottom surface of the cylindrical support block 53 can cooperate with the bearing to seal the bottom surface of the bearing. Therefore, after the sealing top ring 37 is used, a sealed cavity can be formed inside the bearing. Then the vacuum pump 35 can be turned on. Since the vacuum pump 35 is connected to the air delivery groove 39 through the air pipe, the vacuum pump 35 can evacuate the air inside the bearing through the air pipe and the air delivery groove 39, so that a negative pressure environment is formed inside the bearing. An electromagnetic latch is set at the port of the air delivery groove 39. When a negative pressure environment is formed inside the bearing, the electromagnetic latch can be closed. An electromagnetic latch is also set at the port of the oil filling groove 38. At this time, the electromagnetic latch at the port of the oil filling groove 38 can be opened. Since a negative pressure environment is formed inside the bearing, the grease in the delivery groove 32 can enter the inside of the bearing through the oil pipe, thus realizing the oil filling of the bearing.

[0033] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
