Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of bearing ring detection equipment, and in particular to a bearing ring rotating clamping device. Background Art
[0002] Bearing rings are annular parts of radial rolling bearings with one or more raceways. The manufacturing process includes three steps: forging, heat treatment, and monitoring of the grinding process. In addition, damage to the bearing rings needs to be detected during the manufacturing process to ensure the quality of the bearing ring production and prevent accidental breakage due to damage during manufacturing during later use.
[0003] The existing flaw detection method for large bearing rings (2 to 4 meters in diameter) usually requires a probe to detect the bearing ring. The probe needs to drive the bearing ring to rotate during the detection process. However, due to the heavy weight of the bearing ring, it is difficult to manually rotate the bearing ring during detection. To address this problem, devices that drive the bearing ring to rotate automatically have appeared on the market. However, when these devices drive the bearing ring to rotate, their power mostly acts on the side of the bearing ring, and this power needs to be tightly attached to the side of the bearing ring to drive the bearing ring to rotate. However, since the side of the bearing ring is more prone to slipping, especially when the external force is too tight on the side of the bearing ring, the slippage phenomenon is particularly serious. During the rotation of the bearing ring, once the side position of the bearing ring slips, the center position of the bearing ring is likely to be offset, resulting in deviations in the flaw detection results of the bearing ring. In addition, the clamped side cannot be tested.
[0004] In order to overcome the problems existing in the above-mentioned automatic rotation device of the bearing ring, a bearing ring rotation mechanism (patent application number is 20202111580826.6) has now appeared. When the rotating mechanism is working, the bearing ring to be inspected is placed at the inspection station, and the bottom of the bearing ring is respectively supported on the rollers of the three clamping rotating parts. Then the sliding drive part is opened, and the sliding drive part drives the fixed plate to move toward the center position of the inspection station. The setting of the slider can ensure that the movement of the fixed plate remains stable. As the fixed plate moves, the side surface of the bearing ring gradually contacts the sleeves of the three clamping rotating parts, so that the bearing ring is tightly clamped between the three clamping rotating parts, and the elastic activity of the movable plate can prevent the side surface of the bearing ring from being rigidly pressed. It is tightly fitted between the two sleeves, so that the bearing ring can be adaptively clamped between the three clamping rotating parts, and then the rotating drive part is opened. The rotating drive part drives the two rollers to rotate, thereby driving the bearing ring to rotate on the three rollers. At this time, the three sleeves are synchronously and tightly fitted to the side of the bearing ring and rotate with the rotation of the bearing ring. During the rotation of the bearing ring, the rotation force of the two rollers drives the rotation of the bearing ring from the bottom of the bearing ring, and the sleeve only limits the rotation position of the bearing ring. There is no need to press it specially on the side of the bearing ring, thereby avoiding the side of the bearing ring from slipping on the sleeve, ensuring that the bearing ring always remains in the same center position during rotation, ensuring the stability of the bearing ring detection.
[0005] However, the above-mentioned rotating mechanism of the bearing ring (patent application number is 20202111580826.6) has the following defects:
[0006] 1) The rotating mechanism includes three clamping rotating parts and three groups of sliding driving parts and rotating driving parts connected thereto. Each group of sliding driving parts and rotating driving parts respectively includes a motor. The driving of the three groups of sliding driving parts cannot ensure the synchronous sliding of the three clamping rotating parts, and the driving of the three groups of rotating driving parts cannot ensure the synchronous rotation of the three clamping rotating parts. The provision of three groups of driving parts makes the entire drive occupy a larger space.
[0007] 2) When the rotating mechanism is working, the bearing ring to be inspected is placed on three rollers. Due to part processing errors, mechanism assembly errors, and the fact that the bearing ring cannot remain absolutely horizontal and facing downward when being hoisted close to the rollers, there may be a micro gap between the bearing ring and a certain roller when the bearing ring is placed on the three rollers. The friction between the bearing ring and the roller is weakened, thereby affecting the rotational stability of the bearing ring and ultimately affecting the inspection of the bearing ring.

[0024] Compared with the prior art, the present invention has at least the following advantages:
[0025] 1) The bearing ring rotation clamping device provided by the present invention transmits the driving force of a group of clamping driving parts to three groups of rotating clamping mechanisms through a clamping transmission mechanism, so that the three groups of rotating clamping mechanisms can synchronously move toward the center of the detection station to clamp (the bearing ring), and transmits the driving force of a group of rotating driving parts to the three groups of rotating clamping mechanisms through a rotating transmission mechanism, so that the three groups of rotating clamping mechanisms can synchronously drive the workpiece (bearing ring) to rotate, thereby ensuring the stability of clamping and rotation, and ensuring the stability of workpiece detection.
[0026] 2) The bearing ring rotation clamping device provided by the present invention is provided with only one drive box and transmits power to three sets of rotation clamping mechanisms through a transmission mechanism, thereby reducing the space of the drive mechanism.
[0027] 3) When the bearing ring rotating clamping device provided by the present invention is in operation, the bearing ring to be inspected is placed on three rollers, and the bearing ring is rotated and clamped by the rotating clamping mechanism. The bearing ring and the roller are brought into close contact by the flipping and pressing mechanism, thereby increasing the friction between the two, thereby ensuring the stability of the bearing ring rotation and further ensuring the stability of the workpiece inspection.
[0028] 4) The flipping and pressing mechanism is connected to the shaft core of the roller through a bevel gear transmission group, which avoids the need to set up a separate driving mechanism to drive the flipping and pressing mechanism. In the initial stage of the roller rotation, the flipping and pressing mechanism flips under the action of the bevel gear transmission group, thereby effectively pressing the bearing ring; in addition, since the flipping and pressing mechanism does not require a separate driving mechanism, the structure of the flipping and pressing mechanism is simplified and space is saved.

The arc-shaped flip rod is in close contact with the outer side of the shaft clamp under the action of the adjustable pressing assembly so as to flip with the rotation of the flip shaft. Specifically, the adjustable pressing assembly adopts a pressure spring, a spring pressing sleeve and two adjusting bolts. The displacement of the spring pressing sleeve on the flip shaft is adjusted by adjusting the bolts, thereby adjusting the compression force of the pressure spring. The pressure of the compression spring is used to press the arc-shaped flip rod and the shaft clamp, thereby enabling the arc-shaped flip rod to flip with the rotation of the flip shaft. When the arc flips, When the rod flips until the pressing ball presses on the workpiece (bearing ring), the arc-shaped flip rod no longer flips but remains stationary. At this time, the friction plate slips, but the friction force of the friction plate still acts on the arc-shaped flip rod, so that the pressing ball remains in a state of pressing the workpiece. The use of the friction plate avoids the arc-shaped flip rod from direct contact with the shaft clamp and wear, and the friction plate is easy to replace after wear; when the detection is completed, the drive motor is slightly reversed, and the arc-shaped flip rod flips in the opposite direction, so that the pressing ball leaves the workpiece; therefore, the flipping and pressing mechanism realizes automatic pressing of the workpiece, which plays a role in keeping the workpiece stable.

[0049] In the present invention, the working principle of clamping and rotating the bearing ring K during inspection is as follows: the bearing ring to be inspected is placed at the inspection station 1, and the bottom of the bearing ring is respectively supported on three rollers a1, and then the clamping drive is opened, and the clamping drive drives the fixed rotary clamping mechanism 6 and the movable rotary clamping mechanism 7 to move toward the center position of the inspection station 1. Specifically, the first screw rod 43 is driven to rotate by the clamping drive motor 41, and the first drive nut 42 moves on the first screw rod 43, thereby moving the movable rotary clamping mechanism 7, and the corresponding guide rail setting can ensure that the movement of the movable rotary clamping mechanism 7 remains stable. At the same time, Under the action of the clamping transmission mechanism, the second screw rod 47 rotates, and the second drive nut 46 moves on the second screw rod 47, thereby moving the fixed rotary clamping mechanism 6. The setting of the corresponding guide rail can ensure that the movement of the fixed rotary clamping mechanism 6 remains stable. As the movable rotary clamping mechanism 7 and the fixed rotary clamping mechanism 6 move, the side surface of the bearing ring gradually contacts the outer edges of the three rollers a2, so that the bearing ring is tightly clamped between the three clamping rotating members. The elastic activity of the elastic movable component can prevent the side surface of the bearing ring from being rigidly pressed between the two rollers a2, so that the bearing ring can be adaptively clamped between the three clamping rotating members.
[0050] Then the rotary drive component is turned on, and the rotary drive component drives the roller a1 of the movable rotary clamping mechanism 7 and the fixed rotary clamping mechanism 6 to rotate. Specifically, the first rotating rod 45 is driven to rotate by the rotary drive motor 44, and the rotation of the first rotating rod 45 drives the roller a1 to rotate through the gear set, and then drives the bearing ring to rotate on the three rollers a1. At this time, the three rollers a2 are synchronously and tightly fitted to the side of the bearing ring and rotate with the rotation of the bearing ring. During the rotation of the bearing ring, the rotation force of the two rollers a1 drives the rotation of the bearing ring from the bottom of the bearing ring, and the roller a2 only limits the rotation position of the bearing ring, and does not need to be specially pressed on the side of the bearing ring, thereby avoiding the side of the bearing ring from slipping on the roller a2, ensuring that the bearing ring always remains in the same center position during rotation, ensuring the stability of the bearing ring detection.
[0051] The bearing ring rotary clamping device provided in an embodiment of the present invention transmits power to three sets of rotary clamping mechanisms via a transmission mechanism, enabling the three sets of rotary clamping mechanisms to synchronously clamp and rotate a workpiece (bearing ring). This ensures stable clamping and rotation, facilitating workpiece inspection. The bearing ring rotary clamping device provided in an embodiment of the present invention comprises only one set of drive elements, which transmit power to the three sets of rotary clamping mechanisms via a transmission mechanism, thus reducing the space required for the drive mechanisms.
[0052] When the bearing ring rotating clamping device provided by an embodiment of the present invention is working, the bearing ring to be inspected is placed on three rollers a1, and the bearing ring is rotated and clamped by a rotating clamping mechanism. The bearing ring is brought into close contact with the roller a1 by a flipping and pressing mechanism, thereby increasing the friction between the two, thereby ensuring the stability of the bearing ring rotation and further ensuring the stability of the workpiece inspection.

[0055] The elastic movable component includes a sliding plate a6, a spring a7, a spring seat a8 and a second guide rail a9. The spring seat a8 is vertically fixed to one end of the fixed plate a3. The second guide rail a9 is fixed above the fixed plate a3. The sliding plate a6 is slidably connected to the second guide rail a9. The first mounting side plate a4 and the second mounting side plate a5 are fixed on the sliding plate a6.
[0056] The bevel gear transmission group 9 includes a first bevel gear 91 and a second bevel gear 92 that are meshed with each other. The flip pressing mechanism 8 includes a shaft seat 81, two arc-shaped flip rods 82, a pressing rod 83 connecting the two arc-shaped flip rods 82, a flip shaft 84 and two shaft clamps 85. The first bevel gear 91 is connected to the shaft core of the roller a1. The outer side of the first mounting side plate a4 is fixed with two shaft seats 81. The two ends of the flip shaft 84 are installed in the shaft seat 81. The second bevel gear 92 is set on the flip shaft 84. The two shaft clamps 85 are spaced apart. It is fixed on the flip shaft 84, and two arc-shaped flip rods 82 are arranged on the flip shaft 84 at intervals. There is a set gap between the arc-shaped flip rods 82 and the flip shaft 84. One arc-shaped flip rod 82 is located on the outside of the corresponding shaft clamp 85, and the other arc-shaped flip rod 82 is located on the inside of the corresponding shaft clamp 85. Under the action of the adjustable clamping assembly, one arc-shaped flip rod 82 is in close contact with the outside of the shaft clamp 85 so as to flip with the rotation of the flip shaft 84. The pressing ball 86 is arranged below the pressing rod 83.
[0057] The adjustable clamping assembly includes a pressure spring 87, a spring pressure sleeve 88 and two adjusting bolts 89. The spring a7 is sleeved on the flip shaft 84 and is located on the outside of one of the arc-shaped flip rods 82. The spring pressure sleeve 88 is sleeved on the flip shaft 84 and is located on the outside of the spring a7. The adjusting bolt 89 is located on the outside of an axle seat 81 and passes through the axle seat 81 to abut the spring pressure sleeve 88.
[0058] A friction plate 80 is positioned between the arc-shaped flip lever 82 and the shaft clamp 85. The friction plate 80 is sleeved onto the flip shaft 84, with a predetermined gap between them. A T-shaped sleeve 800 is fixed beneath the pressing lever 83 to accommodate the pressing ball 86. The T-shaped sleeve 800 facilitates installation and replacement of the pressing ball 86.
[0059] The flipping and pressing mechanism 8 is connected to the shaft core of the roller a1 through the bevel gear transmission group 9, which avoids the need to set up a separate driving mechanism. The roller a1 is flipped in the initial stage of rotation, thereby effectively pressing the bearing ring in the initial stage of rotation and clamping. In addition, since the flipping and pressing mechanism 8 does not require a separate driving mechanism, the structure of the flipping and pressing mechanism 8 is simplified and space is saved.
[0060] The flip pressing mechanism 8 uses an arc-shaped flip rod 82 for flipping. The arc-shaped flip rod 82 is in close contact with the outer side of the shaft clamp 85 under the action of the adjustable pressing assembly, so as to flip with the rotation of the flip shaft 84. Specifically, the adjustable pressing assembly uses a pressure spring 87, a spring pressing sleeve 88 and two adjusting bolts 89. The displacement of the spring pressing sleeve 88 on the flip shaft 84 is adjusted by adjusting the bolts 89, thereby adjusting the compression force of the pressure spring 87. The pressure of the compression spring a7 is used to press the arc-shaped flip rod 82 against the shaft clamp 85, thereby enabling the arc-shaped flip rod 82 to flip with the rotation of the flip shaft 84. When the arc-shaped flip rod 82 is turned, the arc-shaped flip rod 82 can be turned with the rotation of the flip shaft 84. When the rotating rod 82 flips to the point where the pressing ball 86 presses on the workpiece (bearing ring), the arc-shaped flip rod 82 no longer flips and remains in a pressing and stationary state. At this time, the friction plate 80 slips, but the friction force of the friction plate 80 still acts on the arc-shaped flip rod 82, so that the pressing ball 86 remains in a state of pressing the workpiece. The use of the friction plate 80 avoids direct contact and wear between the arc-shaped flip rod 82 and the shaft clamp 85, and the friction plate is easy to replace after wear; when the detection is completed, the drive motor is slightly reversed, and the arc-shaped flip rod 82 flips in the opposite direction, so that the pressing ball 86 leaves the workpiece; therefore, the flipping and pressing mechanism 8 is used to automatically press the workpiece and keep the workpiece stable.
[0061] Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the present invention is not limited to the embodiments shown herein, but is to be construed in the widest manner consistent with the principles and novel features disclosed herein.
