Description

Technical Field

[0001] The present invention relates to the technical field of bearing accessory assembly, and in particular to an automatic assembly device for bearing production. Background Art

[0002] As an indispensable basic component in the machinery industry, bearings are widely used in various rotating or swinging mechanisms. Their performance and life directly affect the overall quality and reliability of mechanical equipment. Bearings are mainly composed of outer rings, inner rings, balls and cages. With the development of modern manufacturing, the quality requirements for bearings are getting higher and higher. At the same time, in order to improve production efficiency and reduce production costs, bearing manufacturers have gradually introduced automated production lines to achieve efficient and precise bearing assembly.

[0003] In the traditional bearing production process, the ball is one of the key components, which is responsible for providing low-friction rolling contact between the outer ring and the inner ring; however, after the ball is placed between the inner and outer rings, it is usually necessary to center the inner ring by extrusion. Although this process can ensure the accuracy of the position of the inner ring, it also brings significant problems: when the inner ring is extruded, the friction between the inner and outer rings and the ball will increase sharply, and as the friction increases, the ball will be strongly extruded, which may cause scratches or other forms of wear on the ball surface, thereby affecting the roundness and smoothness of the ball and shortening its service life. In addition, ball wear not only affects the performance of a single bearing, but may also cause unstable quality of the entire batch of products and increase the defective rate. Summary of the invention

[0039] When in use, first put an appropriate amount of outer rings into the first loading barrel 602, so that the outer rings are stacked in the first loading barrel 602, and the outer ring on the lowermost side contacts the top of the turntable 4; then put an appropriate amount of inner rings into the second loading barrel 603, so that the inner rings are stacked in the second loading barrel 603, and the inner ring on the lowermost side contacts the top of the turntable 4; then control the first electric push rod 606 to drive the clamping block 607 to clamp the outer ring and the inner ring on the lowermost side respectively; then control the first cylinder 604 to drive the first sliding frame 605, the first electric push rod 606 and the clamping block 607 to move upward, so that the clamping block 607 drives the outer ring and the inner ring to separate from the top of the turntable 4; then align the input pipe for transmitting the lubricating oil with the diverter 12. Then, the lubricating oil is allowed to enter the diverter 12, so that the diverter 12 diverts the lubricating oil and then delivers it to the channel of the connecting frame 8 through the infusion tube 13, and then a proper amount of balls are poured into the hopper 11, so that the balls fall into the channel of the connecting frame 8, so that the lubricating oil adheres to the surface of the balls, and at the same time, the rotating ring 10 is driven to rotate by the servo motor 9, so that the outer side of the rotating ring 10 drives the balls in the channel to rotate through friction, so that the surface of the balls is completely adhered to the lubricating oil, and when the balls in the channel of the connecting frame 8 are lubricated, the lubricated balls will fall into the vertical pipe 14 for stacking, and the balls at the bottom will contact the baffle 1502, and then the turntable motor 3 drives the turntable 4 to rotate intermittently; When the placement hole 401 on the turntable 4 is directly below the first loading barrel 602 and stops, the first electric push rod 606 drives the clamping block 607 to loosen the lowermost outer ring, so that the outer ring in the first loading barrel 602 naturally falls downward due to gravity, so that the lowermost outer ring falls onto the machine table 2, and the lowermost outer ring is in the placement hole 401 on the turntable 4. When the lowermost outer ring falls into the placement hole 401 on the turntable 4, the lowermost outer ring will contact the arc-shaped magnetic plate 5 in the placement hole 401. At this time, the arc-shaped magnetic plate 5 will use magnetic force to attract the lowermost outer ring, thereby limiting the lowermost outer ring, and then A cylinder 604 drives the first sliding frame 605, the first electric push rod 606 and the clamping block 607 to move downward and reset, and then the first electric push rod 606 drives the clamping block 607 to clamp the outer ring on the top of the lowermost outer ring, and then the first cylinder 604 drives the first sliding frame 605, the first electric push rod 606 and the clamping block 607 to move upward to separate the two lowermost outer rings. Then, when the turntable 4 rotates, the turntable 4 will drive the lowermost outer ring to move. By separating the two lowermost outer rings, it can be prevented that when the turntable 4 drives the lowermost outer ring to move, the two outer rings are prevented from being worn due to excessive friction. When the turntable 4 drives the outer ring to move to the bottom of the second loading barrel 603 and stops, the first electric push rod 606 drives the clamping block 607 to loosen the inner ring on the lower side, so that the inner ring in the second loading barrel 603 naturally falls downward under gravity, so that the inner ring on the lower side falls onto the machine table 2, and the inner ring on the lower side is located on the inner side of the inner and outer rings of the storage hole 401, and then the first cylinder 604 drives the first sliding frame 605, the first electric push rod 606 and the clamping block 607 to move downward and reset, and then the first electric push rod 606 drives the clamping block 607 to release the top of the inner ring on the lower side. The first cylinder 604 then drives the first slide frame 605, the first electric push rod 606 and the clamping block 607 to move upward, so that the two inner rings at the bottom are separated. Then, when the turntable 4 rotates, the turntable 4 drives the inner ring at the bottom to move through the outer ring (because the outer ring drives the inner ring to move by contact, so during the movement of the inner and outer rings, the inner ring is located at the inner left side of the outer ring). By separating the two inner rings at the bottom, it is possible to prevent the two inner rings from being worn due to excessive friction when the turntable 4 drives the inner ring at the bottom to move. When the turntable 4 drives the outer ring and the inner ring to be located directly below the vertical tube 14 and stops (the vertical tube 14 is located above the right position on the inner side of the outer ring, so that the inner ring and the vertical tube 14 are respectively located on the left and right sides of the outer ring), the third cylinder 1603 then drives the two spacing rods 1604 to move toward each other so that the two spacing rods 1604 block the inner side of the vertical tube 14, so that the spacing rods 1604 separate the stacked balls in the vertical tube 14 and form an upper and lower part in the vertical tube 14, and then the second electric push rod 1501 drives the baffle 1502 to move forward so that the baffle 1502 no longer blocks the bottom of the vertical tube 14, and then the balls in the lower part of the vertical tube 14 naturally fall into the area between the outer ring and the inner ring. , while the balls in the upper part are blocked by the spacer rod 1604, so that the number of balls falling between the outer ring and the inner ring can be controlled, and then the second sliding frame 1602 is controlled to move downward by the second cylinder 1601, thereby driving the third cylinder 1603 and the spacer rod 1604 to move downward, so that the spacer rod 1604 presses all the balls remaining in the lower part of the vertical tube 14 between the outer ring and the inner ring, and makes the balls in the upper part of the vertical tube 14 fall naturally, and after the spacer rod 1604 presses all the balls in the lower part of the vertical tube 14 between the outer ring and the inner ring, the baffle 1502 is driven to move backward and reset by the second electric push rod 1501, so that the baffle 1502 blocks the bottom of the vertical tube 14 again, and then the two spacer rods 1503 are driven by the third cylinder 1603. 604 move to the side away from each other and reset, so that the spacing rod 1604 no longer blocks the ball in the vertical tube 14, so that the ball at the bottom of the vertical tube 14 naturally falls to contact the baffle 1502, and then the second sliding frame 1602 is controlled by the second cylinder 1601 to move upward and reset, thereby driving the third cylinder 1603 and the spacing rod 1604 to move upward and reset, and then the fourth electric push rod 1705 drives the centering block 1704 to move upward, so that the centering block 1704 passes through the through hole 202 on the machine table 2 and extends into the inner ring, and then the third electric push rod 1703 drives the movable block 1702, the centering block 1704 and the fourth electric push rod 1705 to move right, so that the centering block 1704 drives the inner ring to move rightward on the inner side of the outer ring for centering. During this period, the balls in the inner ring will automatically move and adjust their positions after being squeezed (the balls will be distributed in a ring shape between the inner ring and the outer ring), and because the surface of the balls is stained with lubricating oil, the friction force on the balls can be reduced when the balls are squeezed, thereby protecting the balls, thereby reducing scratches or other forms of wear on the surface of the balls, and increasing the service life of the balls. After the inner ring is centered, the fourth electric push rod 1705 drives the centering block 1704 to move downward and reset, so that the centering block 1704 leaves the through hole 202 on the machine table 2 and the inner ring, and then the third electric push rod 1703 drives the movable block 1702, the centering block 1704 and the fourth electric push rod 1705 to move to the left and reset. After that, when the turntable 4 rotates,The turntable 4 will drive the outer ring, inner ring and balls to move together; When the turntable 4 drives the outer ring, the inner ring and the ball to be located just above the notch 203 of the machine table 2 and stops (at this time, the outer ring is limited by the arc-shaped magnetic plate 5, and the inner wall structure of the outer ring of the bearing and the outer wall structure of the inner ring are both arc surfaces, so the ball is limited by the outer ring, and the inner ring is limited by the ball, so the outer ring, the inner ring and the ball will not fall from the notch 203), the operator can manually install the retainer between the outer ring and the inner ring so that the retainer can limit the ball. After the retainer is completed, the outer ring, the inner ring, the ball and the retainer can form a bearing, and then the turntable 4 will drive the assembled bearing to move; When the turntable 4 drives the assembled bearing to be located directly above the discharge hole 201, the assembled bearing is manually pressed downward to make the assembled bearing leave the storage hole 401 and separate from the arc-shaped magnetic plate 5, so that the assembled bearing falls out of the discharge hole 201 and can be discharged.

[0041] When in use, the holder can be intermittently transported forward by the first conveyor 19; when the turntable 4 drives the outer ring, the inner ring and the ball to be located directly above the notch 203 of the machine table 2 and stops, the fourth cylinder 23 can be used to drive the fixed plate 24, the magnetic block 25 and the pressing rod 27 to move downward until the magnetic block 25 contacts the holder on the first conveyor 19 (the holder is wavy, the top of the wave is aligned with the magnetic block 25, and the bottom of the wave is aligned with the pressing rod 27), so that the magnetic block 25 uses magnetic force to absorb the holder on the first conveyor 19, and then the fourth cylinder 23 drives the fixed plate 24, the magnetic block 25 and the pressing rod 27 to move upward and reset, so that the magnetic block 25 lifts the holder on the first conveyor 19, and then Then, the fourth cylinder 23, the fixed disk 24, the magnetic block 25, the spring 26 and the pressing rod 27 on the lower side are driven by the reduction motor 22 to rotate 180 degrees, so that the magnetic block 25 drives the lower retaining frame to rotate 180 degrees, and then the electric slide rail 20 drives the fixed frame 21 to move to the left, so that the fixed frame 21 drives the reduction motor 22, the fourth cylinder 23, the fixed disk 24, the magnetic block 25 and the pressing rod 27 to move to the left, so that the magnetic block 25 drives the retaining frame to move to the left, and then the two retaining frames are respectively located on the upper and lower sides of the outer ring, and then the fourth cylinder 23 drives the fixed disk 24, the magnetic block 25 and the pressing rod 27 to move toward the side close to the outer ring, so that the magnetic block 25 drives the retaining frame to move toward the side close to the outer ring. When the upper and lower retainers are in contact with the balls, the upper and lower retainers will squeeze the balls to move between the outer ring and the inner ring so that the balls can be automatically adjusted. When the upper and lower retainers are in contact with each other, the upper and lower retainers will limit the balls. At the same time, the upper and lower retainers will prevent the upper and lower magnetic blocks 25 from continuing to move. As the upper and lower fixed plates 24 continue to approach each other, the springs 26 will gradually compress. When the pressing rods 27 are in contact with the upper and lower retainers, the pressing rods 27 will squeeze the retainers so that the upper and lower retainers are docked after being pressed (the retainers themselves carry docking structures in their structures). In this way, the retainers can be automatically installed instead of manually. After the retaining frames on both sides are docked, the fourth cylinder 23 drives the fixed disk 24 and the pressing rod 27 to move to the side away from the outer ring, so that the pressing rod 27 is separated from the retaining frame. During this period, the spring 26 will gradually return to its original state. When the spring 26 is reset, the fixed disk 24 will drive the magnetic block 25 to move to the side away from the outer ring through the spring 26, and then the electric slide rail 20 drives the fixed frame 21 to move to the right and reset, so that the fixed frame 21 drives the reduction motor 22, the fourth cylinder 23, the fixed disk 24, the magnetic block 25 and the pressing rod 27 to move to the right and reset, and then the reduction motor 22 drives the fourth cylinder 23, the fixed disk 24, the magnetic block 25, the spring 26 and the pressing rod 27 on the lower side to rotate 180 degrees in the opposite direction and reset.
