[0001] The invention belongs to the technical field of bearing processing, and in particular relates to a production and processing equipment for oil-free lubrication bearings. Background Art

[0002] Oil-free lubricated bearings are a type of sliding bearings. General sliding bearings need to be added with lubricants such as lubricating oil and grease before working, so as to form a lubricating film on the friction surface and play an effective lubricating role. Oil-free lubricated bearings are made of self-lubricating materials or are pre-filled with lubricants and then sealed for long-term use. No lubricant needs to be added during the working process.

[0003] In the processing of oil-free lubricated bearings, grinding is a key step, which directly affects the surface finish, dimensional accuracy and overall performance of the bearings. There are many common grinding equipment in the prior art that can be used for grinding oil-free lubricated bearings. However, when such equipment is grinding the inner and outer side walls and end faces of oil-free lubricated bearings, it is necessary to continuously adjust the positioning of the oil-free lubricated bearings. This will lead to a decrease in the working efficiency of the grinding operation, which is not conducive to production. Therefore, a device is needed that can grind all surfaces of oil-free lubricated bearings with only one positioning. Summary of the invention

[0023] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0025] like Figure 1-Figure 4 As shown, an oil-free lubrication bearing production and processing equipment provided by an embodiment of the present invention includes a base 1 and also includes:

Two rollers 21 are provided, and the two rollers 21 are symmetrically mounted on the base 1, and one end of the two rollers 21 is connected to each other through a first transmission member 23, and the first transmission member 23 is used to drive the two rollers 21 to rotate synchronously. The first motor 22 is mounted on the base 1, and the output end of the first motor 22 is connected to one end of any one of the rollers 21;

[0027] The positioning module 3 includes two side clamps 31 symmetrically arranged above the base 1, the side clamps 31 are placed in the horizontal direction and perpendicular to the axis of the roller 21, and the base 1 is also provided with a control component 4 for driving the two side clamps 31 to move toward or in the opposite direction at the same time, and each of the side clamps 31 is installed with a vertical plate 32, and the top of the vertical plate 32 is provided with a height-adjustable pressure plate 33;

[0028] The grinding module 5 includes a rotating ring 51 arranged between two rollers 21, and two arc-shaped limit seats 52 symmetrically installed on the base 1, and a sliding groove 511 matching the arc-shaped limit seat 52 is opened on the side wall of the rotating ring 51, and a driving component 6 for driving the rotating ring 51 to rotate is also provided on the base 1, and a notch is provided on the rotating ring 51, and a telescopic member 53 is installed on the inner wall of the rotating ring 51 facing the notch, and a mounting seat 54 is installed at the telescopic end of the telescopic member 53, and a grinding column 55 is installed on the side of the mounting seat 54 facing the center of the rotating ring 51.

[0029] In the embodiment of the present invention, the first transmission member 23 is a pulley belt mechanism, and the telescopic member 53 is an electric telescopic rod. In the initial state, the distance between the two side clamps 31 is in the maximum state, and the notch of the rotating ring 51 is vertically facing upward. When in use, the operator first adjusts the height of the pressing plate 33 so that the bottom surface of the pressing plate 33 remains flush with the highest point of the oil-free bearing. Then, the oil-free bearing to be processed only needs to be placed between the two side clamps 31, and the bottom of the oil-free bearing can be supported by the two rollers 21, and then the control component 4 is started, and the control component 4 can drive the two side clamps 31 to move towards each other at the same time, so that the two side clamps 31 are in contact with the end surface of the oil-free bearing at the same time, and the oil-free bearing is in a vertical state. The side clamp 31 will synchronously drive the vertical plate 32 to move, and the vertical plate 32 drives the pressing plate 33 arranged thereon to move synchronously toward the side close to the oil-free bearing, until the bottom surface of the pressing plate 33 is clamped to the highest point of the side wall of the oil-free bearing. Through the cooperation of the roller 21, the side clamping plate 31 and the pressing plate 33, the oil-free bearing can be limited and placed in a vertical state. Then the driving assembly 6 is started, and the rotating ring 51 is driven to rotate by the driving assembly 6 until the grinding column 55 faces the surface of the oil-free bearing to be polished. Then the telescopic member 53 is controlled to extend, and the telescopic member 53 can drive the grinding column 55 to move to the side close to the oil-free bearing through the mounting seat 54 until the grinding column 55 abuts against the surface of the oil-free bearing to be polished. At this time, the first motor 22 can be started, and the first motor 22 can drive the roller 21 connected thereto to rotate, and the two rollers 21 can be rotated synchronously through the first transmission member 23. Due to the gravity and the limiting effect of related components, the outer side of the oil-free bearing will always maintain a close contact state with the roller 21, so the roller 21 will drive the oil-free bearing to rotate synchronously during the rotation process. In this process, through the continuous contact between the grinding column 55 and the surface to be processed of the oil-free bearing, its surface to be processed can be polished. When one surface is processed, it is only necessary to control the telescopic member 53 to retract, and then control the rotating ring 51 to rotate through the driving assembly 6 until the grinding column 55 points to another surface to be processed, and then the telescopic member 53 will extend and make the grinding column 55 abut against the surface, so as to perform a grinding operation on the surface. The end face and the inner and outer side walls of the oil-free lubrication bearing can be polished by repeating the above process without disassembly and repositioning.

[0030] like Figure 1 and Figure 2As shown, as a preferred embodiment of the present invention, the control component 4 includes a second motor 42, a driving rod 43 and a guide rod 44, and the driving rod 43 and the guide rod 44 are symmetrically distributed on both sides of the base 1, one end of the driving rod 43 is connected to the output end of the second motor 42, and two sliding plates 41 are symmetrically installed on the driving rod 43 and the guide rod 44, the sliding plates 41 and the guide rod 44 are slidingly matched, and the two sliding plates 41 on the guide rod 44 are respectively connected to the same end of the two side clamping plates 31, and the two sliding plates 41 on the driving rod 43 are respectively connected to the other end of the two side clamping plates 31, and the driving rod 43 is symmetrically provided with two threaded sections 431 with opposite spiral directions, and the two sliding plates 41 on the driving rod 43 are respectively installed on the two threaded sections 431.

[0031] In the embodiment of the present invention, when in use, it is only necessary to start the second motor 42, the second motor 42 can drive the driving rod 43 to rotate synchronously, the driving rod 43 can drive the threaded section 431 to rotate synchronously, and through the cooperation between the threaded section 431 and the corresponding sliding plate 41, the two sliding plates 41 can be driven to move toward or in the opposite direction at the same time, and the two sliding plates 41 on the other side will slide synchronously along the axial direction of the guide rod 44 for guidance. The sliding plate 41 drives the corresponding side clamping plate 31 to move synchronously until the two side clamping plates 31 are respectively in contact with the two ends of the oil-free lubricated bearing, so that the oil-free lubricated bearings of different thicknesses can be positioned so that the oil-free lubricated bearings are in a vertical state.

[0032] like Figure 1 and Figure 5 As shown, as a preferred embodiment of the present invention, a guide rod 331 is provided at the bottom of the pressure plate 33, and the guide rod 331 is vertically inserted into the top of the vertical plate 32, and an adjusting bolt 34 is also installed on the top of the vertical plate 32, and the adjusting bolt 34 passes through the pressure plate 33, and a threaded hole matching the adjusting bolt 34 is opened on the pressure plate 33.

[0033] In the embodiment of the present invention, when in use, it is only necessary to screw the adjusting bolt 34, and through the threaded hole on the pressing plate 33 and the adjusting bolt 34, based on the guiding and limiting function of the guide rod 331, the pressing plate 33 can be driven to move linearly in the vertical direction, thereby adjusting the height of the pressing plate 33, so that the bottom surface of the pressing plate 33 is always kept flush with the highest point of the oil-free lubricated bearing. When the side clamping plate 31 fixes the two end surfaces of the oil-free lubricated bearing, the pressing plate 33 will simultaneously clamp the bearing to prevent the oil-free lubricated bearing from jumping up and down during the grinding process.

[0034] like Figure 3 and Figure 4As shown, as a preferred embodiment of the present invention, the driving assembly 6 includes two rotating shafts 62 symmetrically installed in the base 1, one ends of the two rotating shafts 62 are connected to each other through a second transmission member 65, the second transmission member 65 is used to drive the two rotating shafts 62 to rotate synchronously, and one end of one of the rotating shafts 62 is connected to the output end of the third motor 61, each of the rotating shafts 62 is sleeved with a driving gear 63, and an incomplete gear 64 cooperating with the driving gear 63 is provided on the outer wall of the rotating ring 51.

[0035] In the embodiment of the present invention, the angle between the axis of the two rotating shafts 62 and the line connecting the center of the rotating ring 51 is greater than the angle between the two ends of the notch and the line connecting the center of the rotating ring 51, thereby ensuring that the incomplete gear 64 is always in meshing state with at least one of the two driving gears 63. In addition, the second transmission member 65 can adopt a sprocket chain mechanism or a pulley belt mechanism in the prior art, and it is only necessary to ensure that the two rotating shafts 62 can rotate synchronously in the same direction.

[0036] When in use, it is only necessary to start the third motor 61, and the third motor 61 can drive the rotating shaft 62 connected thereto to rotate, and the two rotating shafts 62 can be driven to rotate synchronously through the second transmission member 65, and the rotating shaft 62 can drive the driving gear 63 disposed thereon to rotate. Through the cooperation between the driving gear 63 and the incomplete gear 64, the rotating shaft 62 can drive the rotating ring 51 to rotate with its own circle center as the rotation center, and during the rotation of the rotating ring 51, the incomplete gear 64 is always meshed with at least one driving gear 63.

[0037] like Figure 6 As shown, as a preferred embodiment of the present invention, the grinding column 55 includes a mounting column 551 rotatably mounted on a mounting seat 54, and the mounting seat 54 is also provided with a driving motor for driving the mounting column 551 to rotate, and grinding blocks 552 are arranged in a ring on the mounting column 551, and the particle size of each grinding block 552 is different.

[0038] In the embodiment of the present invention, when in use, the mounting column 551 can be driven to rotate by a driving motor, so that different grinding blocks 552 are in contact with the oil-free lubricated bearing, thereby meeting different grinding requirements.

[0039] Working principle: When in use, the operator first screws the adjusting bolt 34, and through the threaded hole on the pressing plate 33 and the adjusting bolt 34, based on the guiding and limiting function of the guide rod 331, the pressing plate 33 can be driven to move linearly in the vertical direction, thereby adjusting the height of the pressing plate 33, so that the bottom surface of the pressing plate 33 remains flush with the highest point of the oil-free lubricated bearing. Then, just place the oil-free lubricated bearing to be processed between the two side clamps 31, and the bottom of the oil-free lubricated bearing can be supported by two rollers 21. Then start the second motor 42, the second motor 42 can drive the driving rod 43 to rotate synchronously, the driving rod 43 can drive the threaded section 431 to rotate synchronously, and through the cooperation between the threaded section 431 and the corresponding sliding plate 41, the two sliding plates 41 can be driven to move towards or in the opposite direction at the same time, and the two sliding plates 41 on the other side will slide synchronously along the axial direction of the guide rod 44 for guidance. The corresponding side clamps 31 are driven to move synchronously by the sliding plate 41 until the two side clamps 31 are in contact with the end faces of the oil-free bearing respectively, and the oil-free bearing is in a vertical state. The side clamps 31 will synchronously drive the vertical plate 32 to move, and the vertical plate 32 drives the pressure plate 33 arranged thereon to synchronously move toward the side close to the oil-free bearing, until the bottom surface of the pressure plate 33 is clamped to the highest point of the side wall of the oil-free bearing. Through the cooperation of the roller 21, the side clamps 31 and the pressure plate 33, the oil-free bearing can be limited and placed in a vertical state.

Through the cooperation of the driving gear 63 and the incomplete gear 64, the rotating shaft 62 can drive the rotating ring 51 to rotate with its own center of circle as the rotation center until the grinding column 55 faces the surface to be polished of the oil-free bearing. Then the telescopic member 53 is controlled to extend, and the telescopic member 53 can drive the grinding column 55 to move toward the side close to the oil-free bearing through the mounting seat 54 until the grinding column 55 abuts against the surface of the oil-free bearing to be polished. At this time, the first motor 22 can be started, and the first motor 22 can drive the roller 21 connected thereto to rotate, and the two rollers 21 can be rotated synchronously through the first transmission member 23. Under the effect of gravity and the limiting effect of related components, the outer side of the oil-free bearing will always maintain a close contact state with the roller 21, so the roller 21 will drive the oil-free bearing to rotate synchronously during the rotation process. In this process, the surface to be processed can be polished by the continuous contact between the grinding column 55 and the surface to be processed of the oil-free bearing. When one surface is processed, it is only necessary to control the telescopic member 53 to contract, and then control the rotating ring 51 to rotate through the driving assembly 6 until the grinding column 55 points to another surface to be processed, and the telescopic member 53 will extend and make the grinding column 55 abut against the surface, so as to perform a grinding operation on the surface.In addition, the mounting column 551 can be driven to rotate by a driving motor, so that different grinding blocks 552 can contact the oil-free bearing to meet different grinding requirements. Then, the end face and the inner and outer side walls of the oil-free bearing can be ground by repeatedly controlling the movement of the grinding module 5 without disassembly and repositioning.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
