Description

Technical Field

[0001] The invention relates to the technical field of slewing bearing ball filling, and more specifically, to a ball filling device for assembling a double-row ball slewing bearing. Background Art

[0002] Slewing bearing, also known as turntable bearing or rotary bearing, is a large bearing that can bear comprehensive loads and can simultaneously bear large axial and radial loads and overturning moments. It is mainly composed of inner and outer rings, rolling elements, etc., among which slewing bearings include single-row ball slewing bearings and double-row ball slewing bearings.

[0003] Usually, the balls of the double-row ball slewing bearing are installed manually. The balls are inserted into the slewing bearing through the through holes. After each ball is inserted, an isolation block is inserted to separate the two balls. Since the slewing bearing is placed horizontally for installation, the balls inside will roll inside due to too little friction, causing the balls to reflux and be offset. After each ball and isolation block are installed, the staff needs to insert them into the inside with their fingers to make the ball and the isolation block tightly connected. This insertion method has complicated steps and low efficiency.

[0004] Moreover, during manual installation, only one ball and one isolation block are inserted each time, and they can only be inserted in one direction. When installing the ball and the isolation block, it is impossible to insert a ball and a isolation block in both the clockwise and counterclockwise directions of the slewing bearing at the same time, which slows down the installation speed of the ball and reduces the efficiency of installing the ball in the slewing bearing.

[0005] Therefore, it is necessary to design a slewing bearing ball filler with high ball installation efficiency and accuracy to improve the above-mentioned technical problems. Summary of the invention

Before or after installing the balls on the double-row ball slewing bearing, the screws and mounting blocks above it are automatically removed or locked, without the need for manual disassembly by personnel, and the double-row ball slewing bearing is in a vertical or horizontal clamping state. When installing the balls and isolation blocks, due to gravity, the balls and isolation blocks will naturally fall down and stick together, without the need for manual squeezing by personnel, and the isolation blocks and balls are assembled together in sequence and then installed.

[0045] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0046] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0047] For example, see Figure 1-11 The present invention provides the following technical solutions: a ball filler for a double-row ball slewing bearing assembly, comprising a support frame 1 and a double-row ball slewing bearing 4, a first limit plate is fixedly connected to the interior of the support frame 1, a second limit plate is provided on the upper side of the first limit plate and is fixedly connected to the support frame 1, and a controller 2 is fixedly connected to one side of the support frame 1.

[0048] Specifically, the controller 2 is used to control the first solenoid valve 812, the second solenoid valve 813, the third solenoid valve 816, the fourth solenoid valve 815, and the fifth solenoid valve 814 to open or close when assembling ball isolation blocks with different arrangements.

[0049] A screw loosening mechanism 5 for loosening or tightening the screws above the double-row ball slewing bearing 4 is provided inside the support frame 1, a clamping mechanism 6 for clamping the double-row ball slewing bearing 4 is provided on one side of the screw loosening mechanism 5, a feeding mechanism 7 for feeding balls and isolation blocks is provided on the upper side of the second limiting plate, an assembling mechanism 8 for assembling and pushing the balls and isolation blocks is provided inside the feeding mechanism 7, a transmission mechanism 3 for transmitting and vertically and horizontally clamping the double-row ball slewing bearing 4 is provided on the upper side of the first limiting plate.

[0050] In order to automatically tighten the screws on the mounting block 43 and remove the upper mounting block 43 before installing the ball inside the slewing bearing, the following structure is designed:

[0051] See also Figure 2 The screw tightening mechanism 5 includes a first electric slide rail 51 fixedly connected to the inside of the support frame 1, the sliding end of the first electric slide rail 51 is fixedly connected to the second electric slide rail 52, the sliding end of the second electric slide rail 52 is fixedly connected to the guide slide 53, the upper side of the guide slide 53 is fixedly connected to the tightening motor 54, and the output end of the tightening motor 54 passes through the guide slide 53 and is fixedly connected to the hexagonal screw head 55.

[0052] Specifically, the sliding of the sliding end of the first electric slide rail 51 is used to drive the hexagonal screw head 55 to move horizontally, thereby controlling the hexagonal screw head 55 to move from one screw hole on the double-row ball slewing bearing 4 to another screw hole, and the sliding of the sliding end of the second electric slide rail 52 is used to drive the hexagonal screw head 55 to move up and down, thereby controlling the hexagonal screw head 55 to approach or move away from the screw on the double-row ball slewing bearing 4, and the tensioning motor 54 is used to control the rotation of the hexagonal screw head 55, thereby loosening or tightening the screws on the double-row ball slewing bearing 4.

[0053] See also Figure 3 and Figure 4 The transmission mechanism 3 includes a third electric slide rail 31 fixedly connected to the upper side of the first limit plate, a sliding end of the third electric slide rail 31 is fixedly connected to a first cylinder 32, and an output end of the first cylinder 32 is provided with a first gripper 33.

[0054] Specifically, the first clamp 33 is used to clamp the double-row ball slewing bearing 4 vertically or horizontally, the extension of the output end of the first cylinder 32 is used to control the double-row ball slewing bearing 4 to move upward, thereby facilitating the installation of balls thereon, and the movement of the sliding end of the third electric slide rail 31 is used to control the double-row ball slewing bearing 4 to reach the bottom of the clamping mechanism 6 and the assembly mechanism 8 in turn.

[0055] The expansion and contraction of the output end of the double-headed cylinder 331 is used to control the two clamping plates 332 to move closer to or farther from each other, thereby controlling the two clamping plates 332 to clamp the double-row ball slewing bearing 4.

[0056] See also Figure 5 The double-row ball slewing bearing 4 includes an inner ring 41, and a lower outer ring 44 and an upper outer ring 42 are respectively installed on the outer side of the inner ring 41. Two slideways 45 are arranged inside the inner ring 41, and mounting blocks 43 are arranged inside the upper outer ring 42 and the lower outer ring 44.

[0057] Specifically, the interior of the slideway 45 is used to install the balls and the isolation blocks.

[0058] See also Figure 6 The clamping mechanism 6 includes a second cylinder 61 fixedly connected to the inside of the support frame 1, and the output end of the second cylinder 61 is fixedly connected to a second clamping hand 62.

[0059] When the first clamp 33 clamps the double-row ball slewing bearing 4 vertically and horizontally, the tensioning motor 54 is turned on, and the sliding end of the first electric slide rail 51 slides to control the hexagonal screw head 55 to reach above the specified screw, and the second electric slide rail 52 controls the hexagonal screw head 55 to move downward to loosen the tightened screws. When all the screws are loosened, the controller 2 controls the sliding end of the third electric slide rail 31 to move, and the double-row ball slewing bearing 4 is moved to the bottom of the second clamp 62. The output end of the second cylinder 61 extends out to control the second clamp 62 to move downward, and clamps out the mounting block 43 above the double-row ball slewing bearing 4, making it more convenient to install the ball bearings later. When the mounting block 43 is clamped out, the controller 2 controls the third electric slide rail 31 The sliding end continues to move, and when it reaches the bottom of the assembly mechanism 8, the output end of the first clamp 33 extends out to control the double-row ball slewing bearing 4 to move upward, so that one of the slides 45 is close to the assembly mechanism 8, and the assembly mechanism 8 installs the balls and isolation blocks in sequence into the slide 45 of the double-row ball slewing bearing 4. Since the double-row ball slewing bearing 4 is placed vertically and horizontally, when the balls and isolation blocks fall into the slide 45 of the double-row ball slewing bearing 4, due to gravity, the balls and isolation blocks will naturally fall downward and stick together without manual squeezing by personnel, and the isolation blocks and balls are assembled together and then installed. The balls with small friction will press the isolation blocks downward when they fall, effectively preventing the isolation blocks from being stuck in the slide 45 due to excessive friction.

[0060] By automatically removing or locking the screws and mounting block 43 above the double-row ball slewing bearing 4 before or after the ball is installed, there is no need for manual disassembly by personnel, and the double-row ball slewing bearing 4 is in a vertical or horizontal clamping state. When the ball and the isolation block are installed, due to gravity, the ball and the isolation block will naturally fall downward and stick together, without the need for manual squeezing by personnel, and the isolation block and the ball are assembled together in sequence and then installed. The ball with low friction will press the isolation block downward when it falls, effectively preventing the isolation block from being stuck inside the slide 45 due to excessive friction.

[0061] In the second embodiment, when installing the balls and the isolation blocks of the double-row ball slewing bearing 4, only one ball and one isolation block are inserted at a time, and they can only be inserted in one direction. When installing the balls and the isolation blocks, it is impossible to insert a ball and a isolation block in both the clockwise and counterclockwise directions of the slewing bearing at the same time, which slows down the installation speed of the balls and reduces the efficiency of installing the balls in the slewing bearing. Therefore, the following structure is designed to solve the above technical problems.

[0062] The feeding mechanism 7 includes a first vibrating plate 71 fixedly connected above the second limiting plate, a second vibrating plate 72 is provided on one side of the first vibrating plate 71 and is fixedly connected to the second limiting plate, a first conveyor 77 is provided at the discharge port of the first vibrating plate 71, a second conveyor 73 is provided at the discharge port of the second vibrating plate 72, and both the second vibrating plate 72 and the second conveyor 73 are fixedly connected to the second limiting plate.

[0063] Specifically, the first vibration plate 71 is used to vibrate the internal ball bearings for feeding, the second vibration plate 72 is used to vibrate the internal isolation blocks for feeding, the first conveyor 77 is used to transport the ball bearings vibrated by the first vibration plate 71 to the position of the first feeding plate 76, and the second conveyor 73 is used to transport the isolation blocks vibrated by the second vibration plate 72 to the position of the second feeding plate 75.

[0064] See also Figure 7 A fixed block 79 is fixedly connected to the upper side of the second limit plate, and the first hydraulic cylinder 78 and the second hydraulic cylinder 74 are fixedly connected to both sides of the fixed block 79 respectively. The output end of the first hydraulic cylinder 78 is fixedly connected to the first feeding plate 76 for pushing the ball, and the output end of the second hydraulic cylinder 74 is fixedly connected to the second feeding plate 75 for pushing the isolation block.

[0065] Specifically, the extension of the output end of the first hydraulic cylinder 78 is used to control the movement of the first feed plate 76, thereby pushing the ball to the top of the assembly mechanism 8, and the extension of the output end of the second hydraulic cylinder 74 is used to control the movement of the second feed plate 75, thereby pushing the isolation block to the top of the assembly mechanism 8.

[0066] See also Figure 8 The assembly mechanism 8 includes a guide slide box 81 fixedly connected between the second conveyor 73 and the first conveyor 77, one side of the guide slide box 81 is provided with a limit groove 817 and two slide grooves 819, one side of the guide slide box 81 is fixedly connected to the third cylinder 82, the output end of the third cylinder 82 is fixedly connected to the slide plate 83, and the slide plate 83 is slidably connected to the limit groove 817.

[0067] Specifically, the extension of the output end of the third cylinder 82 is used to control the sliding box 811 to move up and down.

[0068] See also Figure 9-11 The guide box 81 is slidably connected to the sliding box 811 inside, and the sliding box 811 is fixedly connected to the slide plate 83. One side of the sliding box 811 is provided with four avoidance grooves 818 of a double-row ball slewing bearing. The interior of the sliding box 811 is provided with a first channel, a second channel, a third channel, a fourth channel, and a fifth channel from left to right.

[0069] Specifically, the first channel, the third channel and the fifth channel are used for passing the isolation block, and the second channel and the fourth channel are used for passing the balls.

[0070] The first channel is fixedly connected to the first solenoid valve 812 on both the upper and lower sides, the second channel is fixedly connected to the second solenoid valve 813 on both the upper and lower sides, the third channel is fixedly connected to the third solenoid valve 816 on both the upper and lower sides, the fourth channel is fixedly connected to the fourth solenoid valve 815 on both the upper and lower sides, and the fifth channel is fixedly connected to the fifth solenoid valve 814 on both the upper and lower sides.

[0071] Specifically, when the first channel needs to pass through the isolation block, the output end of the second hydraulic cylinder 74 extends one-fifth, the second feeding plate 75 pushes the isolation block to the top of the first channel, the first solenoid valve 812 opens, and after the isolation block falls into the first channel, the first solenoid valve 812 closes.

[0072] When the second channel needs to pass the ball, the output end of the first hydraulic cylinder 78 extends four-fifths, the first feeding plate 76 pushes the ball to the top of the second channel, the second solenoid valve 813 opens, and after the ball falls into the second channel, the second solenoid valve 813 closes.

[0073] When the third channel needs to pass through the isolation block, the output end of the second hydraulic cylinder 74 extends three-fifths, the second feeding plate 75 pushes the isolation block to the top of the third channel, the third solenoid valve 816 opens, and after the isolation block falls into the third channel, the third solenoid valve 816 closes.

[0074] When the fourth channel needs to pass the ball, the output end of the first hydraulic cylinder 78 extends two-fifths, the first feeding plate 76 pushes the ball to the top of the fourth channel, the fourth solenoid valve 815 opens, and after the ball falls into the fourth channel, the fourth solenoid valve 815 closes.

[0075] When the fifth channel needs to pass through the isolation block, the output end of the second hydraulic cylinder 74 is fully extended, the second feeding plate 75 pushes the isolation block to the top of the fifth channel, the fifth solenoid valve 814 is opened, and after the isolation block falls into the inside of the fifth channel, the fifth solenoid valve 814 is closed.

[0076] The output end of the first cylinder 32 extends out, and the double-row ball slewing bearing 4 continues to rise. When the slide 45 is close to the bottom of the first baffle 85 and the second baffle 87, the output end of the first hydraulic cylinder 78 extends four-fifths, and the first feeding plate 76 pushes the ball to the top of the second channel. The second solenoid valve 813 opens, and the ball falls into the second channel. Then the second solenoid valve 813 is closed. At the same time as the output end of the third cylinder 82 extends out, the second solenoid valve 813 opens, and the ball falls into the slide 45 and slides to the bottom of the slide 45. At this time, the first ball is installed inside the double-row ball slewing bearing 4.

[0077] When it is necessary to arrange the balls and isolation blocks in a counterclockwise direction, the output end of the second hydraulic cylinder 74 extends one-fifth, while the output end of the first hydraulic cylinder 78 extends four-fifths. The second feed plate 75 pushes the isolation block to the top of the first channel, and the first feed plate 76 pushes the balls to the top of the second channel. At this time, the first solenoid valve 812 and the second solenoid valve 813 are opened at the same time. After the isolation block falls into the first channel and the balls fall into the second channel, the first solenoid valve 812 and the second solenoid valve 813 are closed at the same time.

[0078] When it is necessary to arrange the balls and isolation blocks in the clockwise direction, the output end of the first hydraulic cylinder 78 extends two-fifths, the first feeding plate 76 pushes the balls to the top of the fourth channel, the fourth solenoid valve 815 opens, and after the balls fall into the fourth channel, the fourth solenoid valve 815 closes, and the output end of the first hydraulic cylinder 78 completely retracts and returns to its original position. Then, the output end of the second hydraulic cylinder 74 extends completely, the second feeding plate 75 pushes the isolation block to the top of the fifth channel, the fifth solenoid valve 814 opens, and after the isolation block falls into the fifth channel, the fifth solenoid valve 814 closes, and the output end of the second hydraulic cylinder 74 completely retracts and returns to its original position.

[0079] When the balls and isolation blocks in the clockwise direction, as well as the balls and isolation blocks in the counterclockwise direction are arranged, the output end of the third cylinder 82 extends, the first solenoid valve 812, the second solenoid valve 813, the fourth solenoid valve 815 and the fifth solenoid valve 814 are opened at the same time, the isolation blocks and balls in the counterclockwise direction fall into the slide 45, slide in the counterclockwise direction, and are tightly connected with the previously fallen balls, and the balls and isolation blocks in the clockwise direction fall into the slide 45, slide in the clockwise direction, and are tightly connected with the previously fallen balls, thereby completing the installation of the balls.

[0080] By providing an assembly mechanism 8, the balls and isolation blocks can be pre-arranged and assembled before installation, and according to the different directions of falling, the corresponding arrangement of balls and isolation blocks can be assembled, so that the two assembled groups of balls and isolation blocks can slide into the interior of the slideway 45 from two different directions at the same time, which speeds up the installation time of the balls and isolation blocks and achieves a high ball installation efficiency.

[0081] Embodiment three, when installing the balls and isolation blocks of the double-row ball slewing bearing 4, since the balls and isolation blocks are installed in two directions at the same time, the curvature above the slide 45 is too small. When the two balls fall to the upper slide 45, they may fall in one direction at the same time, resulting in incorrect arrangement of the balls and isolation blocks. Moreover, when the balls and isolation blocks in two directions are about to be arranged, the curvature of the slide 45 above the double-row ball slewing bearing 4 is too small and cannot fall by gravity, so that the balls and isolation blocks cannot be tightly connected, resulting in the final isolation block being unable to be inserted into the slide 45. Therefore, the following structure is designed to solve the above technical problems.

[0082] The lower side of the third cylinder 82 is provided with the fourth cylinder 84 and the fifth cylinder 86 in sequence from top to bottom and is fixedly connected to the guide slide box 81, the output end of the fourth cylinder 84 is fixedly connected to the first push plate 841, the output end of the fifth cylinder 86 is fixedly connected to the second push plate 861, the first push plate 841 and the second push plate 861 are both slidably connected to the slide groove 819, and the lower side of the guide slide box 81 is hinged with the first baffle plate 85 and the second baffle plate 87 respectively.

[0083] Specifically, the extension of the output end of the fourth cylinder 84 is used to control the first push plate 841 to push the ball and the isolation block in the counterclockwise direction, and the extension of the output end of the fifth cylinder 86 is used to control the second push plate 861 to push the ball and the isolation block in the clockwise direction.

[0084] In the initial state, the double-row ball slewing bearing 4 moves upward until the first baffle 85 and the second baffle 87 are pressed and closed by the slide 45, and the output ends of the fourth cylinder 84 and the fifth cylinder 86 are in a fully retracted state, and the first push plate 841 and the second push plate 861 are located inside the third channel. When the output end of the third cylinder 82 extends, the first solenoid valve 812, the second solenoid valve 813, the third solenoid valve 816, the fourth solenoid valve 815, and the fifth solenoid valve 814 are opened, and two groups of balls and isolation blocks fall to the top of the first baffle 85 and the second baffle 87, and the output end of the fourth cylinder 84 extends to push the balls and isolation blocks in the counterclockwise direction into the slide 45, and the output end of the fifth cylinder 86 extends to push the balls and isolation blocks in the clockwise direction into the slide 45.

[0085] When there are three spacers and two balls left to be installed, the arrangement of the three spacers and two balls is as follows: Fig.11, the output end of the third cylinder 82 extends out, the third solenoid valve 816 opens, and the sliding box 811 is driven by the output end of the third cylinder 82 to move upward along the inner wall of the guide sliding box 81, and the first push plate 841 and the second push plate 861 indirectly move to the lower part of the inner part of the guide sliding box 81. At this time, the first push plate 841 and the second push plate 861 will not be blocked by the partition of the third channel, and the output ends of the fourth cylinder 84 and the fifth cylinder 86 are fully extended, and the first push plate 841 and the second push plate 861 are respectively pushed to the outside of the sliding box 811, and the isolation block and the ball on the slide 45 are indirectly pressed, and the third solenoid valve 816 is closed, and the output end of the third cylinder 82 is retracted. At this time, the isolation blocks and the balls are respectively installed in the first channel, the second channel, the third channel, the fourth channel, and the fifth channel, and the first solenoid valve 812, the second solenoid valve 813, the third solenoid valve 816, the fourth solenoid valve 815, and the fifth solenoid valve 814 are opened, the output end of the third cylinder 82 extends out, the three isolation blocks and the two balls fall above the first baffle 85 and the second baffle 87, the output ends of the fourth cylinder 84 and the fifth cylinder 86 begin to retract, clamp the three isolation blocks and the two balls so that they are tightly connected, and the double-row ball slewing bearing 4 begins to descend until the first baffle 85 and the second baffle 87 are parallel to each other, the output end of the third cylinder 82 retracts, the second solenoid valve 813, the third solenoid valve 816, and the fourth solenoid valve 815 are closed, and the output end of the third cylinder 82 retracts to control the sliding box 811 to descend and push the three isolation blocks and the two balls to the inside of the slide 45, thereby completing the installation of all the balls.

[0086] The first push plate 841 and the second push plate 861 are controlled to slide by the fourth cylinder 84 and the fifth cylinder 86, which can not only accurately push the two groups of isolation blocks and ball bearings to the correct direction of the slide 45, but also indirectly press the isolation blocks and ball bearings already installed on the slide 45 before installing the last three isolation blocks and two ball bearings. When installing the last three isolation blocks and two ball bearings, they are pressed so that they can be pressed into the interior of the slide 45 more easily, thereby achieving the effect of high ball installation accuracy and convenient installation.

[0087] In the fourth embodiment, since the inner ring 41 inside the double-row ball slewing bearing 4 is in a rotationally connected relationship with the upper outer ring 42 and the lower outer ring 44, when the first push plate 841 and the second push plate 861 push the isolation blocks and the balls, they will hit the inner ring 41, causing the inner ring 41 to rotate. Since the remaining isolation blocks and balls need to be pressed in together in the end, the remaining isolation blocks and balls need to be aligned with the notch position. The rotation of the inner ring 41 will cause the notch position to shift, making it impossible to accurately press the isolation blocks and balls into the notch, resulting in difficulty in pressing the isolation blocks and balls in.

[0088] See also Figure 4The first gripper 33 includes a double-headed cylinder 331 fixedly connected to the first cylinder 32, and the two output ends of the double-headed cylinder 331 are fixedly connected to a clamping plate 332, and a positioning block 333 is fixedly connected to the upper side of each clamping plate 332. A rotating groove is provided on the upper side of each positioning block 333, and a gear block 335 is provided inside the rotating groove. The gear block 335 is a triangular block, and a first rotating shaft is fixedly connected inside the gear block 335. One end of the first rotating shaft is connected to the bearing of the positioning block 333 and the other end passes through the positioning block 333. A first motor 334 is fixedly connected to one side of the positioning block 333 and a second motor 336 is fixedly connected to the upper side. The output end of the first motor 334 is fixedly connected to the other end of the first rotating shaft, and the output end of the second motor 336 passes through the positioning block 333 and is fixedly connected to a rotating wheel 337, and the rotating wheel 337 passes through the positioning block 333.

[0089] Specifically, the second clamp 62 is used to clamp or loosen the mounting block 43 with the screws loosened, the extension of the output end of the second cylinder 61 is used to control the second clamp 62 to approach or move away from the mounting block 43, the rotation of the output end of the first motor 334 is used to control the gear block 335 to rotate along the first rotating shaft, and the rotation of the output end of the second motor 336 is used to control the rotation of the wheel 337.

[0090] When it is necessary to install the isolation block and the ball inside the double-row ball slewing bearing 4, the second clamp 62 clamps the lower outer ring 44 and the upper outer ring 42, and the first motor 334 and the second motor 336 are started at the same time. The first motor 334 controls the tooth block 335 to rotate ninety degrees, and the output end of the second motor 336 rotates the control wheel 337 to rotate continuously, thereby indirectly controlling the inner ring 41 to rotate until the tooth block 335 rotated ninety degrees is stuck in the tooth column inside the inner ring 41, and the output end of the second motor 336 stops rotating. At this time, the inner ring 41 is stuck by the tooth block and the inner ring 41 cannot be rotated. At this time, the position of the gap is difficult to shift, which effectively prevents the inner ring 41 from rotating and causing the position of the gap to shift, thereby preventing the isolation block and the ball from being accurately pressed into the inside of the gap, thereby achieving a high accuracy of the isolation block and the ball pressing position.

The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
