Description

Technical Field

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

[0002] A bearing is a precision mechanical component that converts the sliding friction between the rotating shaft and the shaft seat into rolling friction, thereby reducing friction losses. Rolling bearings are generally composed of four parts: an inner ring, an outer ring, rolling elements, and a cage. The inner ring is used to match the shaft and rotate with the shaft; the outer ring is used to match the bearing seat and play a supporting role; the rolling elements are evenly distributed between the inner and outer rings with the help of the cage. The shape, size, and number of rolling elements directly affect the 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 and play a lubricating role.

[0003] During the production and assembly process of the bearing, the inner ring and the outer ring are first loaded, the inner ring is placed into the outer ring, and the outer wall on one side of the inner ring is made to fit with the inner wall on one side of the outer ring. At this time, a gap for placing the rolling body is formed between the outer wall on the other side of the inner ring and the inner wall of the outer ring; then multiple rolling bodies are placed between the inner ring and the outer ring, so that the multiple rolling bodies are all rollingly set 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 set, and the rolling body is rollingly clamped between the inner ring and the outer ring; then the multiple rolling bodies are dispersed and positioned, so that the multiple rolling bodies are evenly spaced between the inner ring and the outer ring; then the retaining frame is installed, so that the multiple rolling bodies are stably and evenly distributed; then the number of rolling bodies 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 the ball bearings are balls. During assembly, a certain amount of balls need to be assembled between the outer ring and the inner ring. In the prior art, in addition to assembly on the automated production line, manual assembly is required, requiring workers to manually grab and count the corresponding number. This method has a high work intensity and reduces assembly efficiency. At the same time, the manual material picking error is large. Summary of the invention

[0037] Working principle of the first embodiment:

[0038] In the initial state, the material taking part 10 is placed inside the conical tube 8 and is buried by the balls 13. At this time, the elastic diaphragm 69 in the receiving hole 16 is in a recessed state and points to the hemispherical shell 14. When the material taking part 10 is controlled to rise, the balls 13 in the conical tube 8 enter the corresponding receiving holes 16, thereby realizing quantitative material taking of the balls 13, replacing manual material taking, improving work 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 Figure 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 stopper on the first conveyor frame 2 is used to block the inner ring 6 and the outer ring 5 after the delivery of the ball 13 is completed, and control the electric push rod 36 thereon to extend. At this time, the electric push rod 36 on the second stopper is synchronously contracted to block the adjacent inner ring 6 and the outer ring 5 at the ball 13 delivery station (the position below the conical cylinder 8 is the ball 13 delivery station). After the delivery of the ball 13 is completed, the inner ring 6 and the outer ring 5 are conveyed to the next process for continued assembly.

[0046] The third stopper on the third conveying frame 27 is used to block the inner ring 6 near the storage tube 4 and control the electric push rod 36 thereon to extend. At this time, the electric push rod 36 on the fourth stopper is synchronously contracted to block the adjacent inner ring 6.

[0047] The outer ring 5 in the present application has the same thickness as the inner ring 6, and the blocking column 11 is used to block the outer ring 5 at the bottom. The groups of outer rings 5 ​​in the storage tube 4 are coaxially arranged from top to bottom, and an outer ring is placed inside each group of outer rings 5. The bottom of the storage tube 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 the present application, after the outer ring 11 at the bottom of the storage tube 4 and the corresponding inner ring 6 are transported away by the first conveyor belt 29, the second-to-last layer of outer rings 5 ​​and the corresponding inner rings 6 in the storage tube 4 fall onto the first conveyor belt 29 under the action of gravity. At this time, under the transmission of the second conveyor belt 30, The corresponding outer ring 5 is sent into the storage tube 4 to fill the position. When the material picking part 10 completes the rising and picking, the push rod 57 abuts against the pressure sensor 58. The pressure sensor 58 transmits the signal to the controller 34. The controller 34 controls the electric push rod 36 on the third stop part to extend and the electric push rod 36 on the fourth stop part to contract. The inner ring 6 on the third conveyor belt 31 close to the storage tube 4 is transported into the storage tube 4. When the push rod 57 is detached from the pressure sensor 58, the controller 34 controls the electric push rod 36 on the third stop part to contract and the electric push rod 36 on the fourth stop part to extend and reset.

[0048] The outer ring 5 and the inner ring 6 are conveyed into the receiving tube 4 in turn by 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 bottom of the conical cylinder 8 by the first conveyor belt 29, so that the inner ring 6 and the outer ring 5 are automatically put on. Under the obstruction of the first stopper, the corresponding outer ring 5 is blocked, and the corresponding inner ring 6 slides with the first conveyor belt 29, so that the outer wall on one side of the inner ring 6 fits with the inner wall on one side of the outer ring 5. At this time, a gap for placing the ball 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 can realize automatic positioning of the inner ring 6 and the outer ring 5 before placing the ball 13.

[0052] An annular plate 52 is fixed to the bottom end of the sliding tube 12; a first iron ring 53 is fixed to the top of the annular plate 52; a first annular electromagnetic suction cup 54 electrically connected to the output end of the controller 34 is fixed to the bottom of the conical tube 8; a supporting spring 55 is fixed between the annular plate 52 and the bottom of the conical tube 8; an extension plate 56 is fixed to the side surface of the annular plate 52; a push rod 57 is fixed to the top of the extension plate 56; a pressure sensor 58 electrically connected to the input end of the controller 34 is fixed to the bottom of the conical tube 8.

[0053] A conical funnel 59 is fixed to the side of the support plate 7 below the ball outlet hole 20; a curved plate 60 is fixed to the top of the conical funnel 59; a support plate 61 is fixed to the side of the storage tube 4; a guide rod 62 is fixed between the support plate 61 and the L-shaped support plate 3; a lifting ring 63 that slides with the guide rod 62 is slidably provided on the outer side of the storage tube 4; a connecting spring 64 that is sleeved on the guide rod 62 is fixed between the support plate 61 and the lifting ring 63; a second annular electromagnetic suction cup 65 that is electrically connected to the output end of the controller 34 is fixed to the bottom surface of the support plate 61; a second iron ring 66 that is coaxial with the guide rod 62 is fixed to the surface of the lifting ring 63; a delivery pipe 67 is fixed through the top of the lifting ring 63; a serpentine hose 68 is connected between the delivery pipe 67 and the bottom of the conical funnel 59; the inner diameters of the serpentine hose 68 and the delivery pipe 67 are larger than the diameter of the ball 13.

[0054] Working principle of the third embodiment:

[0055] A large number of balls 13 for assembly are placed in the space below the conical guide cover 19 inside the conical cylinder 8. In the initial state, the material picker 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 and points to the inside of the hemispherical shell 14. The first annular electromagnetic suction cup 54 is controlled to be energized to attract the first iron ring 53, and the supporting spring 55 is compressed, so that the slide tube 12 on the material picker 10 slides and rises along the slide hole 9, and the balls 13 in the conical cylinder 8 enter the corresponding receiving holes 16. The material picker 10 rises until each group of balls 13 is placed above the conical guide cover 19, so as to realize quantitative material picking of the balls 13, replace manual material picking, improve work efficiency, and at the same time, improve the accuracy of material picking.

[0056] When the material taking part 10 completes the lifting and taking of 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 start-up driving motor 39 to drive the rotating rod 40 to rotate slowly, thereby driving the spiral groove 43 to rotate slowly, and then driving the ball head 45 to slide and descend along the rotating spiral groove 43, so that the ejector part 23 slides and descends along the fixed seat 22. During the descent of the ejector part 23, the ejector pin 46 thereon is driven to descend and be inserted into the vertical hole 48. During the downward sliding of the ejector pin 46, the piston rod 51 is driven to slide and descend, thereby making The piston plate 49 slides down along the corresponding piston cylinder 17, the return spring 50 is compressed, and the air in the piston cylinder 17 is pressed into the hemispherical shell 14 through the air supply pipe 70, so that each group of elastic diaphragms 69 is inflated and expanded, and the balls 13 placed in the receiving holes 16 are pushed out from the receiving holes 16 and fall into the outer peripheral side area of ​​the tapered guide cover 19. During this process, the rotation of the rotating rod 40 drives the shifting plate 72 to rotate slowly along the outer peripheral side of the tapered guide cover 19, so as to "sweep" the balls 13 at different positions into the ball outlet holes 20, thereby improving the discharge efficiency of the balls 13.
