Description

Technical Field

[0001] The present invention relates to the technical field of bearing processing, and more specifically, it relates to a bearing assembly device. Background Art

[0002] A bearing is a precision mechanical component that changes the sliding friction between a rotating shaft and a shaft seat into rolling friction, thereby reducing frictional losses. A rolling bearing generally consists of four parts: an inner ring, an outer ring, rolling elements, and a cage. The function of the inner ring is to cooperate with the shaft and rotate together with the shaft; the function of the outer ring is to cooperate with the bearing seat and play a supporting role; the rolling elements are evenly distributed between the inner ring and the outer ring by means of the cage, and the shape, size, and number of the rolling elements directly affect the service performance and life of the rolling bearing; the cage can evenly distribute the rolling elements, prevent the rolling elements from falling off, and guide the rolling elements to rotate to play a lubricating role.

[0003] During the production and assembly process of a bearing, first, the inner ring and the outer ring are loaded. The inner ring is placed into the outer ring, and the outer wall on one side of the inner ring is fitted with the inner wall on one side of the outer ring. At this time, a gap for placing the rolling elements is formed between the outer wall on the other side of the inner ring and the inner wall of the outer ring; then, a plurality of rolling elements are placed between the inner ring and the outer ring, so that the plurality of rolling elements are all rotatably arranged between the inner ring and the outer ring; then, the inner ring is moved so that the inner ring and the outer ring are coaxially arranged. At this time, the rolling elements are rotatably clamped between the inner ring and the outer ring; then, the plurality of rolling elements are dispersed and positioned so that the plurality of rolling elements are evenly spaced between the inner ring and the outer ring; then, the cage is installed so that the plurality of rolling elements are stably and evenly distributed; then, the number of rolling elements between the inner ring and the outer ring is detected and cleaning is completed; finally, lubricating oil is applied and an annular cover is installed.

[0004] During the bearing installation and production process, the rolling elements in a ball bearing are balls. During assembly, a certain quantity of balls need to be assembled between the outer ring and the inner ring. In the prior art, except for assembly on an automated production line, manual assembly is required. Workers need to manually grasp and count the corresponding quantity. This method has a high working intensity, reduces the assembly efficiency, and at the same time, there are large errors in manual material taking. Summary of the Invention

[0036] A bearing assembly device. Specifically, the assembly frame 1 includes a first conveying frame 2; L-shaped support plates 3 are symmetrically fixed on the top of the first conveying frame 2; a receiving pipe 4 is fixed between the two L-shaped support plates 3; a number of coaxial outer rings 5 are stacked inside the receiving pipe 4, and a number of inner rings 6 are stacked inside the outer rings 5; a first stop portion and a second stop portion are sequentially and fixedly installed on the side of the first conveying frame 2; a support plate 7 is fixed on the top of the receiving pipe 4; a tapered cylinder 8 is fixed at the end of the support plate 7; a sliding hole 9 is opened on the inner bottom surface of the tapered cylinder 8; a material taking portion 10 is slidably arranged in the sliding hole 9; a stop post 11 is fixed at the bottom of the tapered cylinder 8; the material taking portion 10 includes a sliding pipe 12 slidably matched with the sliding hole 9; a number of ball bearings 13 are placed between the tapered cylinder 8 and the sliding pipe 12; a hemispherical shell 14 is fixed on the top of the sliding pipe 12; a tapered cover 15 is fixed on the top of the hemispherical shell 14; a number of receiving holes 16 adapted to the ball bearings 13 are evenly opened on the outer peripheral side surface of the tapered cover 15; an elastic diaphragm 69 is arranged inside the receiving hole 16; a piston cylinder 17 is fixedly penetrated between the hemispherical shell 14 and the tapered cover 15; an air delivery pipe 70 is communicated between the bottom of the piston cylinder 17 and the hemispherical shell 14; a piston portion 18 is slidably arranged inside the piston cylinder 17; a tapered guiding cover 19 slidably matched with the sliding pipe 12 is fixed on the inner wall of the tapered cylinder 8; a ball outlet hole 20 with a diameter larger than that of the ball bearing 13 is opened on the inner wall of the tapered cylinder 8 above the tapered guiding cover 19; vertical rods 21 are symmetrically fixed on the outer peripheral side surface of the tapered guiding cover 19; a fixed seat 22 is fixed between the tops of the two vertical rods 21; a thimble portion 23 is slidably arranged on the fixed seat 22.

[0037] The working principle of this Example 1:

[0038] In the initial state, the material taking portion 10 is placed inside the tapered cylinder 8 and buried by the ball bearings 13. At this time, the elastic diaphragm 69 in the receiving hole 16 is in a concave state pointing to the hemispherical shell 14. When the material taking portion 10 is controlled to rise, the ball bearings 13 in the tapered cylinder 8 enter the corresponding receiving holes 16, realizing the quantitative taking of the ball bearings 13, replacing manual material taking, improving the working efficiency, and at the same time, improving the accuracy of material taking.

[0039] By controlling the ejector pin 23 to slide down along the fixing seat 22, the piston 18 is driven to descend along the inner wall of the piston cylinder 17, and the air in the piston cylinder 17 is transported into the hemispherical shell 14 through the air pipe 70. Each group of elastic diaphragms 69 is inflated and expanded, and the corresponding balls 13 are ejected from the corresponding receiving holes 16, thereby realizing automatic unloading of the balls 13 and improving work efficiency.

[0040] For example 2, please refer to Figures 1-11 The second embodiment makes the following improvements on the basis of the first embodiment. Specifically, a first feed port 24 is provided on the side surface of the storage tube 4, and a second feed port 25 is provided on the side surface thereof above the first feed port 24; a second conveying rack 26 and a third conveying rack 27 are fixed on the side surface of the storage tube 4 respectively, which are opposite to the first feed port 24 and the second feed port 25; the second conveying rack 26 and the third conveying rack 27 are used for conveying the outer ring 5 and the inner ring 6 respectively.

[0041] The first conveyor frame 2, the second conveyor frame 26 and the third conveyor frame 27 are all symmetrically and rotatably provided with conveyor rollers 28; the first conveyor belt 29, the second conveyor belt 30 and the third conveyor belt 31 are respectively and transmission-installed between the two opposite conveyor rollers 28; the servo motors 32 are fixedly installed on the sides of the first conveyor frame 2, the second conveyor frame 26 and the third conveyor frame 27; each servo motor 32 is respectively fixedly connected to one end of the corresponding conveyor roller 28.

[0042] An L-shaped fixing plate 33 is fixed on the top of the conical cylinder 8; a controller 34 is fixedly installed on the top of the L-shaped fixing plate 33; a third stopper and a fourth stopper are fixed to the side of the third conveyor frame 27 in sequence; ear plates 35 are fixed to the sides of the first conveyor frame 2 and the third conveyor frame 27; the first stopper, the second stopper, the third stopper and the fourth stopper all include an electric push rod 36 fixedly installed on the corresponding ear plate 35; a baffle plate 37 is fixed to the telescopic end of the electric push rod 36; a baffle rod 38 is symmetrically fixed to the bottom surface of the baffle plate 37; the output end of the controller 34 is electrically connected to each servo motor 32 and the electric push rod 36 respectively.

[0043] Working principle of the second embodiment:

[0044] Each group of servo motors 32 is controlled to start, driving the corresponding conveying rollers 28 to rotate, thereby driving the first conveyor belt 29, the second conveyor belt 30, and the third conveyor belt 31 to transmit respectively. The first conveyor belt 29 transmits and transports the inner ring 6 and the outer ring 5 after the ring is ferruled, the second conveyor belt 30 transmits and transports the outer ring 5, and the third conveyor belt 31 transmits and transports the inner ring 6.

[0045] The first stop portion on the first conveyor rack 2 is used to block the inner ring 6 and the outer ring 5 after the placement of the balls 13 is completed. The electric push rod 36 thereon is controlled to extend. At this time, the electric push rod 36 on the second stop portion contracts synchronously to block the adjacent inner ring 6 and outer ring 5 at the ball 13 placement station (the position under the conical cylinder 8 is the ball 13 placement station). The inner ring 6 and outer ring 5 after the placement of the balls 13 are conveyed to the next process for continued assembly.

[0046] The third stop portion on the third conveyor rack 27 is used to block the inner ring 6 near the receiving pipe 4, and the electric push rod 36 thereon is controlled to extend. At this time, the electric push rod 36 on the fourth stop portion contracts synchronously to block the adjacent inner ring 6.

[0047] In this application, the outer ring 5 and the inner ring 6 have the same thickness. The stop post 11 is used to block the lowermost outer ring 5. The outer rings 5 in each group in the receiving pipe 4 are coaxially arranged from top to bottom. An outer ring is placed inside each group of outer rings 5. The bottom of the receiving pipe 4 is higher than the first conveyor belt 29, and its height is exactly the thickness of a single group of outer rings 5. In this application, after the lowermost outer ring 5 in the receiving pipe 4 and the corresponding inner ring 6 are conveyed away by the first conveyor belt 29, the second-lowermost outer ring 5 in the receiving pipe 4 and the corresponding inner ring 6 fall onto the first conveyor belt 29 under the action of gravity. At this time, the corresponding outer ring 5 is sent into the receiving pipe 4 for replenishment under the drive of the second conveyor belt 30. When the material taking portion 10 completes the upward material taking, the ejector rod 57 abuts against the pressure sensor 58, and the pressure sensor 58 transmits a signal to the controller 34. The controller 34 controls the electric push rod 36 on the third stop portion to extend, and the electric push rod 36 on the fourth stop portion contracts. The inner ring 6 near the receiving pipe 4 on the third conveyor belt 31 is conveyed into the receiving pipe 4. When the ejector rod 57 disengages from the pressure sensor 58, the controller 34 controls the electric push rod 36 on the third stop portion to contract, and the electric push rod 36 on the fourth stop portion extends and resets.

[0048] The outer ring 5 and the inner ring 6 are sequentially conveyed into the receiving pipe 4 through the second conveyor belt 30 and the third conveyor belt 31, and the corresponding outer ring 5 and inner ring 6 are conveyed to the lower part of the conical cylinder 8 through the first conveyor belt 29 to realize the automatic sleeving of the inner ring 6 and the outer ring 5. Under the blocking of the first stop portion, the corresponding outer ring 5 is blocked, and the corresponding inner ring 6 slides along with the first conveyor belt 29, so that the outer wall on one side of the inner ring 6 fits against the inner wall on one side of the outer ring 5. At this time, a gap for placing the balls 13 is formed between the outer wall on the other side of the inner ring 6 and the inner wall of the outer ring 5. The whole device has a simple structure and a high degree of automation, and realizes the automatic positioning of the inner ring 6 and the outer ring 5 before the balls 13 are placed.

[0054] The working principle of the third embodiment:

[0055] A large number of balls 13 for assembly are put into the space inside the conical cylinder 8 below the conical guide cover 19. In the initial state, the material taking part 10 is placed inside the conical cylinder 8 and buried by the balls 13. In the initial state, the elastic diaphragm 69 in the receiving hole 16 is in a concave state pointing inside the hemispherical shell 14. Control the first annular electromagnetic chuck 54 to be energized to attract the first iron ring 53, and the support spring 55 is compressed, so that the sliding tube 12 on the material taking part 10 slides upward along the sliding hole 9. The balls 13 in the conical cylinder 8 enter the corresponding receiving holes 16, and the material taking part 10 rises until each group of balls 13 is placed above the conical guide cover 19, realizing the quantitative material taking of the balls 13, replacing manual material taking, improving the working efficiency, and at the same time, improving the accuracy of material taking.

[0056] When the material taking part 10 finishes rising and taking materials, the ejector rod 57 abuts against the pressure sensor 58, and the pressure sensor 58 transmits a signal to the controller 34. The controller 34 controls the driving motor 39 to start and drive the rotating rod 40 to rotate slowly, thereby driving the spiral groove 43 to rotate slowly, and further driving the ball head 45 to slide downward along the rotating spiral groove 43, so that the ejector needle part 23 slides downward along the fixed seat 22. During the process of the ejector needle part 23 descending, the ejector needle 46 on it is driven to descend and insert into the vertical hole 48. During the process of the ejector needle 46 sliding downward, the piston rod 51 is driven to slide downward, and further the piston plate 49 slides downward along the corresponding piston cylinder 17, and the return spring 50 is compressed. The air in the piston cylinder 17 is pressed into the hemispherical shell 14 through the air delivery pipe 70, so that each group of elastic diaphragms 69 is inflated and enlarged, and the balls 13 placed in the receiving holes 16 are ejected from the receiving holes 16 and fall to the area on the outer peripheral side surface of the conical guide cover 19. During this process, the rotation of the rotating rod 40 drives the baffle 72 to rotate slowly along the outer peripheral side surface of the conical guide cover 19, and "sweeps" the balls 13 at different positions into the ball outlet holes 20, improving the discharging efficiency of the balls 13.

[0057] In the initial state, the second annular electromagnetic chuck 65 is energized and in the energized state to attract the second iron ring 66, and the connecting spring 64 is compressed. Control the second annular electromagnetic chuck 65 to lose power, and under the elastic restoring force of the connecting spring 64, drive the lifting ring 63 to slide downward along the guide rod 62, so that the delivery pipe 67 is inserted into the gap formed between the outer wall of the other side of the inner ring 6 and the inner wall of the outer ring 5 for putting the balls 13. The balls 13 fall into the conical funnel 59 through the ball outlet holes 20, and then through the slow descent of the snake-shaped hose 68, and then are sent into the gap formed between the outer wall of the other side of the inner ring 6 and the inner wall of the outer ring 5 through the delivery pipe 67, completing the quantitative delivery and assembly of the balls 13.
