Description

Technical Field

[0002] High-speed gearbox is an important component of industrial transmission system, widely used in wind power, aerospace, automobile manufacturing and heavy machinery. High-speed gearbox will generate vibration during operation. Since the bearing seat and the box body of the high-speed gearbox are in hard contact, in order to effectively reduce vibration and improve load stability, an elastic ring structure is usually added between the bearing seat and the gearbox. The inner and outer ring walls of the elastic ring are staggered with a series of bosses, which separate the continuous oil film into multiple small oil chambers in the inner and outer cavities. Under the excitation of the journal, the elastic ring produces radial bending deformation, which can automatically adjust the oil film gap between the inner and outer cavities, and can buffer the impact of transient loads on the bearing seat.

[0003] During the production process of the elastic support ring, the surface of the initially formed elastic support ring is relatively rough, and the inner and outer surfaces of the elastic support ring need to be polished by grinding equipment to make the surface smooth.

[0004] In the prior art, grinding equipment needs to grind the inner and outer surfaces of the elastic support ring separately. When grinding the inner surface, the outer surface of the workpiece needs to be fixed and an inner cylindrical grinding head is used to grind the inner surface. When grinding the outer surface, the inner surface of the workpiece needs to be fixed and an outer cylindrical grinding head is used to grind the outer surface.

[0017] Beneficial effects of the present invention: The elastic ring damper grinding device of the present invention is adopted, by setting a clamping and grinding mechanism and an oil driving mechanism, in the clamping and grinding mechanism, the guide plates of the inner and outer rings are used to clamp the elastic support ring with size difference between the grinding rollers of the inner and outer rings and the clamping roller, and the grinding roller and the clamping roller can always fit the outer wall of the elastic support ring. Under the operating principle of the oil driving mechanism, during a propulsion process of the electric telescopic rod, the stroke can be divided into two stages. In the first stage, only the grinding roller of the inner ring rotates to the inner surface of the elastic support ring. The outer surface of the elastic support ring is ground, and the remaining grinding rollers and the clamping rollers are always in rolling friction in the rotation direction of the elastic support ring. In the second stage, only the grinding rollers of the outer ring rotate to grind the outer surface of the elastic support ring, and the remaining grinding rollers and the clamping rollers are always in rolling friction in the rotation direction of the elastic support ring.

The operation is simple and the grinding efficiency is higher. Secondly, during the grinding process, there are staggered bosses on the inner and outer surfaces of the elastic support ring. When grinding the inner surface, the oil pressure in the first oil cylinder of the inner ring is in an unpressurized state, and the grinding roller and the clamping roller will adaptively displace when rolling over the boss. In order to maintain the oil pressure in the first oil cylinder of the inner ring at this time, the third piston plate will adaptively slide in the second outer cylinder, and the small sliding stroke of the third piston plate caused by the boss is not enough for the push rod at its bottom to press the opening and closing switch, and the oil pressure in the first oil cylinder of the outer ring is in a continuously pressurized state, which can improve the clamping stability of the elastic support ring when encountering the boss. Similarly, adaptive adjustment can be performed when grinding the outer surface, so that when there are protrusions on the surface of the elastic support ring, its inner and outer surfaces can also be ground.

[0024] The clamping and polishing mechanism includes two groups of first oil cylinders 5 relatively arranged on the top of the base 2, a bottom plate 4 is fixed between the bottom of the two groups of first oil cylinders 5 and the top of the base 2, a first spring 51 is fixedly connected to the inner wall of the end of each group of first oil cylinders 5, and the end of the first spring 51 is fixedly connected to a first piston plate 52 that is slidably matched with the inner wall of the first oil cylinder 5, and a connecting column 53 is fixed to the outer wall of the first piston plate 52; A first oil pressure balancing component is disposed on the top of each group of first oil cylinders 5 , and the first oil pressure balancing component is used to regulate the oil pressure inside the first oil cylinders 5 .

[0025] A motor 511 is installed at the end of the connecting column 53 of one group of clamping and grinding mechanisms, and the output end of the motor 511 is connected to a grinding roller 512 through a ratchet assembly. The tops of the connecting columns 53 of the other clamping and grinding mechanisms are rotatably connected to clamping rollers 513, and the tops of the grinding rollers 512 and the clamping rollers 513 are both set to conical structures. Guide plates 514 are relatively fixed on the tops of the two groups of connecting columns 53 of each group of clamping and grinding mechanisms. The guide plates 514 are respectively close to the corresponding grinding rollers 512 and clamping rollers 513, and the upper ends of the two groups of guide plates 514 of each group of clamping and grinding mechanisms are relatively provided with extension ends inclined toward the grinding rollers 512 or the clamping rollers 513.

[0026] A switch assembly is provided at the bottom of the first oil cylinder 5 of one group of clamping and polishing mechanisms, and the switch assembly is used to control the on and off state of the motor 511 according to the internal pressure of the first oil cylinder 5.

[0027] The first oil pressure balancing assembly includes a first outer cylinder 54 fixed to the top of the first oil cylinder 5 and connected thereto, a second spring 55 is fixed to the top inner wall of the first outer cylinder 54, the bottom of the second spring 55 is connected to a second piston plate 56 that slides with the inner wall of the first outer cylinder 54, and an air hole is opened at the top of the first outer cylinder 54.

[0028] The switch assembly includes a second outer cylinder 57 fixed to the bottom of the first oil cylinder 5 and connected thereto, an opening and closing switch 58 is installed on the inner wall of the bottom of the second outer cylinder 57, a third spring 59 is fixed to the inner wall of the bottom end of the second outer cylinder 57, the top end of the third spring 59 is fixedly connected to a third piston plate 510 that slides with the inner wall of the second outer cylinder 57, a top rod facing the opening and closing switch 58 is fixed to the bottom of the third piston plate 510, and an air hole is opened at the bottom of the second outer cylinder 57.

[0029] As this embodiment, the elastic support ring is placed between the guide plates 514 of the inner ring and the outer ring. The bottom of the elastic support ring may be located at any position between the guide plates 514 of the inner and outer rings, and the upper ends of the guide plates 514 of the inner and outer rings are inclined toward the gap between the grinding rollers 512 or the clamping rollers 513. At this time, the elastic support ring is pressed, and according to the size of the elastic support ring, its bottom squeezes the inclined surface of the guide plate 514 of the inner ring or the outer ring in each group of clamping and grinding mechanisms and moves downward, and the corresponding guide plates 514 of the outer ring or the inner ring are displaced accordingly. If the size of the elastic support ring is smaller than the gap position in the initial state, the guide plate 514 of the inner ring is squeezed and contracted inward, and the support ring is stuck between the grinding rollers 512 or the clamping rollers 513 of the inner and outer rings. At this time, the inner ring The connecting column 53 pushes the first piston plate 52 to slide inward and squeezes the first spring 51 and the oil in the first oil cylinder 5, and the first spring 51 of the outer ring resets the corresponding distance and pushes the first piston plate 52 to slide inward, and the grinding rollers 512 or clamping rollers 513 of the inner and outer rings always fit the inner and outer surfaces of the elastic support ring and perform preliminary clamping under the elastic force of the first spring 51, wherein when the first piston plates 52 of the inner and outer rings are relatively displaced in the first oil cylinder 5, in order to ensure the pressure balance in the first oil cylinder 5, the second piston plate 56 of the inner ring slides upward in the first outer cylinder 54 and continues to squeeze the second spring 55, while the second piston plate 56 of the outer ring slides downward in the first outer cylinder 54, and the second spring 55 resets the corresponding distance; Under the action of the oil driving mechanism, when grinding the inner surface of the elastic ring, the third piston plate 510 will drive the push rod to press the on-off switch 58 at the bottom, and the on-off switch 58 of the outer ring is electrically connected to the motor 511 of the inner ring, so that the motor 511 of the inner ring starts to rotate counterclockwise, and the ratchet assembly between the output end of the motor 511 and its corresponding grinding roller 512 is in a non-rotating direction, so that the motor 511 drives the grinding roller 512 to rotate counterclockwise through the ratchet assembly, and the clamping rollers 513 of the inner ring are all attached to the inner wall of the elastic support ring, and the grinding rollers 512 of the inner ring will drive the support ring to rotate counterclockwise while grinding the inner surface of the support ring. The grinding roller 512 located on the outer ring is rotating clockwise at this time. In this rotation direction, the ratchet assembly between the output end of the motor 511 and the corresponding grinding roller 512 is in a rotatable direction, and the clamping roller 513 of the outer ring is in contact with the outer surface of the support ring and rolls. After the push rod presses the opening and closing switch 58, the oil is still transported to the first oil cylinder 5 of the outer ring. At this time, the oil will push the second piston plate 56 of the outer ring to slide upward in the first outer cylinder 54, and the second piston plate 56 will squeeze the second spring 55. As the second spring 55 is squeezed, the elastic force continues to increase, causing the oil pressure in the first oil cylinder 5 to increase continuously, and the grinding roller 513 of the outer ring is 12 and the clamping force of the clamping roller 513 on the outer surface of the support ring are also increasing synchronously, and the inner surface of the support ring is polished by the grinding roller 512 of the inner ring driven by the motor 511 to rotate rapidly. At the same time, the support ring rotates under the action of rolling friction, and the inner surface of the support ring can be completely polished. When polishing the outer surface, the bottom push rod of the third piston plate 510 of the inner ring presses the opening and closing switch 58, and the motor 511 of the outer ring starts to rotate counterclockwise. At this time, the grinding roller 512 of the outer ring and the ratchet assembly of the motor 511 cannot rotate in this direction, so that the motor 511 drives the grinding roller 512 of the outer ring to rotate counterclockwise, then the outer The grinding roller 512 of the inner ring will drive the support ring to rotate clockwise while grinding the outer surface of the support ring. The grinding roller 512 located on the inner ring rotates clockwise at this time. In this rotation direction, the ratchet assembly between the output end of the motor 511 and the inner ring grinding roller 512 is in a rotatable direction. As the oil continues to be transported, the clamping force of the inner ring grinding roller 512 and the clamping roller 513 on the inner surface of the support ring is also increased synchronously. The outer surface of the support ring is polished by the outer ring grinding roller 512 rotating rapidly under the drive of the motor 511. At the same time, the support ring rotates under the action of rolling friction, so that the outer surface of the support ring can be completely polished.

[0030] As an implementation method, Figure 7 , Figure 8 , Fig. 9 As shown, the oil driving mechanism includes a fixed plate 6 fixed on the processing table 1, a second oil cylinder 61 is fixed on the top of the fixed plate 6, a connecting cylinder 62 connected to the second oil cylinder 61 is fixed on the top of the second oil cylinder 61, and an oil filling port is provided on the top of the second oil cylinder 61; An electric telescopic rod 63 is installed on the top of the fixed plate 6, and the telescopic end of the electric telescopic rod 63 is arranged to be sealed and slidably matched with the bottom of the second oil cylinder 61, and the end of the electric telescopic rod 63 is fixed with a fourth piston plate 64 that is slidably matched with the inner wall of the second oil cylinder 61, and the top of the fourth piston plate 64 is fixed with a top column 65 that is sealed and slidably matched with the inner wall of the connecting cylinder 62, and the lower end outer wall of the top column 65 is provided with an annular groove 66; A second oil pressure balancing assembly is disposed at the bottom of the second oil cylinder 61 to balance the pressure at the bottom of the fourth piston plate 64 , and a third oil pressure balancing assembly is disposed at the top of the connecting cylinder 62 to balance the internal pressure of the connecting cylinder 62 .

[0031] The oil drive mechanism also includes a first connecting tube 613 connected at an equiangular angle to the outer wall of the second oil cylinder 61, the other end of the first connecting tube 613 is respectively connected to the first oil cylinder 5 on the outside of each group of clamping and polishing mechanisms, and the outer wall of the lower end of the connecting tube 62 is connected at an equiangular angle to a second connecting tube 614, the other end of the second connecting tube 614 is respectively connected to the first oil cylinder 5 on the inside of each group of clamping and polishing mechanisms.

[0032] The second oil pressure balancing assembly includes a third outer cylinder 67 fixed to the bottom of the second oil cylinder 61 and connected thereto, a fourth spring 68 is fixedly connected to the inner wall of the bottom end of the third outer cylinder 67, a fifth piston plate 69 slidably matched with the inner wall of the second oil cylinder 61 is fixedly connected to the top of the fourth spring 68, and an air hole is opened at the bottom of the third outer cylinder 67.

[0033] The third oil pressure balancing assembly includes a fourth outer cylinder 610 fixed to the top of the connecting cylinder 62 and connected thereto, and an oil filling port is provided at the bottom of the fourth outer cylinder 610, a fifth spring 611 is fixed to the inner wall of the top of the fourth outer cylinder 610, a sixth piston plate 612 slidingly matched with the inner wall of the fourth outer cylinder 610 is fixed to the bottom end of the fifth spring 611, and an air hole is opened at the top of the fourth outer cylinder 610.

[0034] As the present embodiment, since the controller 3 is electrically connected to the electric telescopic rod 63, the electric telescopic rod 63 is started by controlling the controller 3, and the electric telescopic rod 63 pushes the fourth piston plate 64 to slide upward in the second oil cylinder 61 to above the connecting port of the first connecting tube 613, and the connecting port of the first connecting tube 613 is located in the middle of the second oil cylinder 61, located in the area below the fourth piston plate 64. To ensure pressure balance, the fifth piston plate 69 slides to the top in the third outer cylinder 67, pushing the oil inside it to below the fourth piston plate 64, located in the area above the fourth piston plate 64, and the oil is transported to the first oil cylinder 5 of the outer ring through the first connecting tube 613, respectively, to achieve clamping of the outer surface of the elastic support ring and grinding of the inner surface. When the fourth piston plate 64 moves past the connecting port of the first connecting tube 613, the top column 65 will slide the same stroke in the connecting cylinder 62, and the top of the top column 65 will push the oil to the fourth outer cylinder 610 The sixth piston plate 612 is pushed inwardly, so that the sixth piston plate 612 squeezes the fifth spring 611, and the top of the annular groove 66 located on the outer wall of the top column 65 just moves to below the connecting port of the second connecting tube 614 and the connecting tube 62. Then, when the electric telescopic rod 63 continues to drive the fourth piston plate 64 to slide up, the bottom end of the fourth piston plate 64 moves through the connecting port of the first connecting tube 613, and begins to draw back the oil in the first oil cylinder 5 delivered to the outer ring through the first connecting tube 613, relieves the increased pressure in the first oil cylinder 5, stops grinding the inner surface, and the fourth piston plate 64 continues to push the top column 65 upward, and the oil at the top of the fourth piston plate 64 is transported to the second connecting tube 614 through the annular groove 66 and begins to be transported to the first oil cylinder 5 of the inner circle. Similarly, the inner surface of the elastic support ring is positioned and the outer surface is polished until the fourth piston plate 64 moves to the top of the second oil cylinder 61 and is in the maximum stroke state, and the electric telescopic rod 63 stops.

[0035] Specifically: First, in the initial state, the interior of the fourth outer cylinder 610 is located in the area below the sixth piston plate 612, the interior of the connecting cylinder 62, the interior of the second oil cylinder 61 is located in the top and bottom areas of the fourth piston plate 64, the interior of the third outer cylinder 67 is located in the area above the fifth piston plate 69, the interior of the first connecting pipe 613 and the second connecting pipe 614, the area on one side of the first piston plate 52 in the first oil cylinder 5 of the inner and outer circles, and the area below the second piston plate 56 in the first outer cylinder 54 are all filled with oil, wherein the second spring 55 and the first spring 51 in the first oil cylinder 5 of the inner and outer circles are both in a compressed state, so that the grinding rollers 512 or the clamping rollers 513 in each group of clamping and grinding mechanisms are in a state of resistance, and under the premise of this state, the elastic force of the first spring 51 of the inner and outer circles is greater than the elastic force of the second spring 55, the elastic force of the third spring 59 is less than the elastic force of the second spring 55, and the elastic force of the fifth spring 611 is greater than the elastic force of the first spring 51.

[0036] Since there may be a small difference in the size of the elastic support ring, the elastic support ring is placed between the guide plates 514 of the inner ring and the outer ring. The bottom of the elastic support ring may be located at any position between the guide plates 514 of the inner and outer rings, and the upper ends of the guide plates 514 of the inner and outer rings are inclined toward the gap between the grinding rollers 512 or the clamping rollers 513. At this time, the elastic support ring is pressed, and according to the size of the elastic support ring, its bottom squeezes the inclined surface of the guide plate 514 of the inner ring or the outer ring in each set of clamping and grinding mechanisms and moves downward, and the corresponding guide plate 514 of the outer ring or the inner ring is displaced accordingly. If the size of the elastic support ring is smaller than the gap position in the initial state, the guide plate 514 of the inner ring is squeezed and contracted inward, and the support ring is stuck between the grinding rollers 512 or the clamping rollers 513 of the inner and outer rings. At this time, the connecting column 53 of the inner ring pushes the first piston plate 52 to slide inward and squeezes the first spring 51 and the oil in the first oil cylinder 5, and the first spring 51 of the outer ring resets the corresponding distance and pushes the first piston plate 52 to slide inward, and the grinding rollers 512 or clamping rollers 513 of the inner and outer rings always fit the inner and outer surfaces of the elastic support ring and perform preliminary clamping under the elastic force of the first spring 51. When the first piston plates 52 of the inner and outer rings are relatively displaced in the first oil cylinder 5, in order to ensure the pressure balance in the first oil cylinder 5, the second piston plate 56 of the inner ring slides upward in the first outer cylinder 54 and continues to squeeze the second spring 55, while the second piston plate 56 of the outer ring slides downward in the first outer cylinder 54, and the second spring 55 resets the corresponding distance.

[0037] Then, since the controller 3 is electrically connected to the electric telescopic rod 63, the electric telescopic rod 63 is started by controlling the controller 3, and the electric telescopic rod 63 pushes the fourth piston plate 64 to slide upward in the second oil cylinder 61 to above the connecting port of the first connecting tube 613, and the connecting port of the first connecting tube 613 is located in the middle of the second oil cylinder 61, in the area below the fourth piston plate 64. To ensure pressure balance, the fifth piston plate 69 slides to the top in the third outer cylinder 67, pushing the oil inside it to below the fourth piston plate 64, in the area above the fourth piston plate 64, and the oil passes The oil is respectively transported to the first oil cylinder 5 of the outer ring through the first connecting pipe 613. Since the grinding roller 512 or the clamping roller 513 of the outer ring fits the outer surface of the elastic support ring, when the oil is continuously transported to the first oil cylinder 5, the oil will first squeeze the third piston plate 510 to slide downward in the second outer cylinder 57 until the third piston plate 510 drives the push rod to press the on-off switch 58 at the bottom, and the on-off switch 58 of the outer ring is electrically connected to the motor 511 of the inner ring, so that the motor 511 of the inner ring starts to rotate counterclockwise, and the ratchet assembly between the output end of the motor 511 and its corresponding grinding roller 512 is In the non-rotatable direction, the motor 511 drives the grinding roller 512 to rotate counterclockwise through the ratchet assembly, and the clamping roller 513 of the inner ring is attached to the inner wall of the elastic support ring. The grinding roller 512 of the inner ring drives the support ring to rotate counterclockwise while grinding the inner surface of the support ring. The grinding roller 512 located on the outer ring rotates clockwise at this time. In this rotation direction, the ratchet assembly between the output end of the motor 511 and the corresponding grinding roller 512 is in a rotatable direction, and the clamping roller 513 of the outer ring is attached to the outer surface of the support ring and rolls. After the push rod presses the on-off switch 58, the oil is still flowing to the first oil of the outer ring. The oil is transported in the liquid cylinder 5. At this time, the oil will push the second piston plate 56 of the outer ring to slide upward in the first outer cylinder 54, and the second piston plate 56 will squeeze the second spring 55. As the second spring 55 is squeezed and the elastic force is continuously increased, the oil pressure of the first oil cylinder 5 is continuously increased, and the clamping force of the grinding roller 512 and the clamping roller 513 of the outer ring on the outer surface of the support ring is also increased synchronously. The inner surface of the support ring is polished by the rapid rotation of the grinding roller 512 of the inner ring driven by the motor 511. At the same time, the support ring rotates under the action of rolling friction, and the inner surface of the support ring can be completely polished.

[0038] When the fourth piston plate 64 moves past the connection port of the first connecting tube 613, the top column 65 will slide the same stroke in the connecting tube 62, and the top of the top column 65 will push the oil into the fourth outer tube 610, so that the sixth piston plate 612 squeezes the fifth spring 611, and the top of the annular groove 66 located on the outer wall of the top column 65 just moves below the connection port of the second connecting tube 614 and the connecting tube 62. Then, when the electric telescopic rod 63 continues to drive the fourth piston plate 64 to slide upward, the bottom end of the fourth piston plate 64 moves past the first connecting tube The connecting port 613 starts to draw back the oil in the first oil cylinder 5 delivered to the outer ring through the first connecting pipe 613, relieves the increased pressure in the first oil cylinder 5, and at the same time, the push rod at the bottom of the third piston plate 510 is reset, stops pressing the on-off switch 58, the motor 511 of the inner ring stops rotating, and the fourth piston plate 64 continues to push the push column 65 upward, and the oil on the top of the fourth piston plate 64 is delivered to the second connecting pipe 614 through the annular groove 66 and starts to be delivered to the first oil cylinder 5 of the inner ring, and similarly The top rod at the bottom of the third piston plate 510 of the ring presses the on-off switch 58, and the motor 511 of the outer ring starts to rotate counterclockwise. At this time, the grinding roller 512 of the outer ring and the ratchet assembly of the motor 511 cannot rotate in this direction, so that the motor 511 drives the grinding roller 512 of the outer ring to rotate counterclockwise. Then, the grinding roller 512 of the outer ring will drive the support ring to rotate clockwise while grinding the outer surface of the support ring. The grinding roller 512 located in the inner ring rotates clockwise at this time. In this rotation direction, the output end of the motor 511 is connected to the grinding roller of the inner ring. The ratchet assembly between the grinding rollers 512 is rotatable. As the oil continues to be transported, the clamping force of the inner ring grinding roller 512 and the clamping roller 513 on the inner surface of the support ring is synchronously increased. The outer surface of the support ring is polished by the outer ring grinding roller 512 driven by the motor 511 and rotating rapidly. At the same time, the support ring rotates under the action of rolling friction, and the outer surface of the support ring can be completely polished until the fourth piston plate 64 moves to the top of the second oil cylinder 61 and is in the maximum stroke state, and the electric telescopic rod 63 stops.

[0039] Finally, in the above working process, the fourth piston plate 64 moves from the initial position to the top of the second oil cylinder 61, which is a grinding process. In this process, the inner and outer surfaces of the elastic support ring can be ground. Even if there are staggered bosses on the inner and outer surfaces of the elastic support ring during the grinding process, when grinding the inner surface, the oil pressure of the inner ring of the first oil cylinder 5 is in an unpressurized state, and the grinding roller 512 and the clamping roller 513 will adaptively displace when rolling over the boss, causing the connecting column 53 to drive the first piston plate 52 to slide. In order to maintain the oil pressure in the inner ring of the first oil cylinder 5 at this time, the third piston plate 510 will adaptively slide in the second outer cylinder 57, and the small sliding stroke of the third piston plate 510 caused by the boss is not enough to press the bottom push rod of the elastic support ring to press the opening and closing switch 58. Similarly, adaptive adjustment can also be performed when grinding the outer surface, so that when there are protrusions on the surface of the elastic support ring, its inner and outer surfaces can also be ground.
