Description

Technical Field

[0002] A bearing is a transmission component used in various machines. It consists of a bearing inner ring, a bearing outer ring, rollers, a roller cage and other components. The various components of a bearing are generally produced independently. After the production of each component of the bearing is completed, they are assembled to achieve the production of a complete bearing.

[0003] In the prior art, in order to improve the work efficiency of bearing assembly, assembly equipment is generally used to realize the assembly production of bearings. The bearing assembly equipment generally sets the inner ring of the bearing coaxially inside the outer ring of the bearing, and then controls the inner ring of the bearing to move eccentrically so that a certain number of rollers are conveyed to the space between the inner ring of the bearing and the outer ring of the bearing.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] For specific embodiment 1, please refer to Figure 1-14 The present invention is an assembly control system for rolling bearing manufacturing, comprising a feeding control mechanism 1, a bearing ring conveying pipe 2, a bearing output pipe 5, an assembly power mechanism 6 and an eccentric control mechanism 7; the feeding control mechanism 1 comprises a conveying guide frame 101, a material guide channel 102 is provided inside the conveying guide frame 101, a feeding pusher 103 is provided on one side of the conveying guide frame 101, and a steel ball conveying pipe 104 connected to the material guide channel 102 is symmetrically installed on the other side of the conveying guide frame 101; the bearing ring conveying pipe 2 is fixed on the conveying guide frame 101 and is connected to the material guide channel 102, a coaxial bearing inner ring 3 and a bearing outer ring 4 are sleeved on the bearing ring conveying pipe 2, and the feeding pusher 103 is slidably arranged on the bearing The bearing output tube 5 is symmetrically arranged on both sides of the bearing ring conveying tube 2 and fixedly connected to the conveying guide frame 101, the bearing output tube 5 is connected to the material guide channel 102, and the steel ball conveying tube 104 is arranged one by one with the bearing output tube 5; the assembly power mechanism 6 is installed on the feeding control mechanism 1, and the assembly power mechanism 6 includes an assembly power wheel 601 that reciprocates horizontally; the eccentric control mechanism 7 is installed on the feeding control mechanism 1, and the eccentric control mechanism 7 includes two symmetrically arranged force-driven wheels 701, and an eccentric control part 702 corresponding to the force-driven wheels 701 is slidably arranged inside the material guide channel 102, and the eccentric control part 702 is coaxially arranged with the corresponding force-driven wheels 701 and the two rotate synchronously.

[0036] In this embodiment of the present invention, the feeding control mechanism 1 also includes a supporting frame 105, two tube mounting frames 106 are symmetrically fixedly arranged at the bottom of the supporting frame 105, the bearing output tube 5 is installed inside the corresponding tube mounting frame 106, and a feeding port 107 is provided on the side of the conveying guide frame 101 away from the supporting frame 105, and the feeding port 107 is connected to the material guide channel 102; a first limiting groove 108 is provided on the top of the conveying guide frame 101, the inner diameter of the bearing output tube 5 is the same as the diameter of the corresponding feeding port 107, and the outer diameter of the bearing outer ring 4 is the same as the inner diameter of the bearing output tube 5 (the inner wall of the bearing output tube 5 is set to a smooth structure), so as to ensure that the assembled bearing can slide into the corresponding bearing output tube 5 along the feeding port 107, and the bearing entering the bearing output tube 5 slides out and completes the collection, and the bearing ring is conveyed. The outer diameter of the tube 2 is smaller than the diameter of the corresponding feed port 107, and the outer diameter of the bearing inner ring 3 is the same as the inner diameter of the bearing ring delivery tube 2, ensuring that the concentric bearing inner ring 3 and the bearing outer ring 4 can be synchronously pushed into the material guide channel 102 along the corresponding feed port 107. Since the outer diameter of the bearing outer ring 4 is the same as the height of the material guide channel 102, and the axial width of the bearing outer ring 4 is the same as the width of the material guide channel 102, it can be ensured that the bearing outer ring 4 pushed into the material guide channel 102 can only slide along the extension direction of the material guide channel 102. A second limiting groove 109 and a limiting guide rod 110 are respectively provided on the top of the supporting frame 105, and a gas discharge pipe 111 adapted to the position of the bearing output pipe 5 is installed on the conveying guide frame 101. The gas discharge pipe 111 is connected to the material guide channel 102 and an electromagnetic valve 112 is installed thereon.

[0037] In this embodiment of the present invention, the assembly power mechanism 6 also includes a horizontal support platform 602 arranged between the supporting frame 105 and the conveying guide frame 101, and a third limiting groove 603 is opened on the top of the horizontal support platform 602, and a vertical moving rod 604 is slidably arranged inside the second limiting groove 109, and a first fixed frame 605 slidably sleeved on the limiting guide rod 110 is fixedly arranged on the side surface of the vertical moving rod 604. Through the joint action of the limiting guide rod 110 and the second limiting groove 109, it is ensured that the vertical moving rod 604 will not deflect during the movement process. The first fixed frame 605 is fixedly connected to the horizontal support platform 602, and a motor seat 606 is fixedly arranged on the side of the horizontal support platform 602 relative to the first fixed frame 605, and the output shaft of the first motor 607 installed on one side of the motor seat 606 is connected to the assembly power wheel 601.

[0038] The assembly power mechanism 6 also includes a second motor fixedly mounted at the bottom of the carrier frame 105, the output end of the second motor is connected to a vertical power shaft 608 that penetrates the carrier frame 105, and a horizontal toggle frame 609 located above the conveying guide frame 101 is fixedly arranged on the side surface of the vertical power shaft 608, and a toggle channel 610 is opened on the surface of the horizontal toggle frame 609, and the vertical moving rod 604 is slidably fitted inside the toggle channel 610; in the initial state, the positions of various mechanisms are as follows Figure 1 As shown, at this time, the assembled power wheel 601 is located at the position of the bearing ring delivery tube 2, and the eccentric control part 702 on the left is located on the right side of the feeding port 107 on the left, that is, the eccentric control part 702 on the left is located in the middle position between the left bearing output tube 5 and the bearing ring delivery tube 2, and the eccentric control part 702 on the right is located in the middle position between the right bearing output tube 5 and the bearing ring delivery tube 2 (the assembled power wheel 601 is in the middle position between the two eccentric control parts 702).

[0039] In this embodiment of the present invention, the eccentric control mechanism 7 also includes two symmetrically arranged vertical mounting seats 703, which are fixedly connected by a linkage plate 704. The vertical mounting seat 703 is slidably connected to the third limiting groove 603. A horizontal mounting shaft 705 is rotatably arranged on the vertical mounting seat 703. The force-driven rotating wheel 701 and the eccentric control part 702 are both fixedly arranged on the corresponding horizontal mounting shaft 705. A reciprocating moving frame 706 slidably connected to the first limiting groove 108 is arranged between the horizontal support platform 602 and the conveying guide frame 101 (it should be noted that an outer ring positioning frame fixed to the reciprocating moving frame 706 is slidably arranged inside the material guide channel 102, and the eccentric control part 702 is located on the inner side of the corresponding outer ring positioning frame. The two outer ring positioning frames are not shown in the figure). The horizontal mounting shaft 705 is rotatably arranged on the reciprocating moving frame 706, and a first gear 707 is fixedly installed on the side surface of the horizontal mounting shaft 705.

[0040] A second fixing frame 708 is fixedly installed on one side of the supporting frame 105, and a horizontal moving rod 709 is slidably arranged on the second fixing frame 708 (a section of the horizontal moving rod 709 that passes through the second fixing frame 708 is not shown in the figure, and the horizontal moving rod 709 always slides with the second fixing frame 708 without being separated), and a mounting plate 710 is fixedly arranged on one end of the horizontal moving rod 709, and the mounting plate 710 is fixedly arranged on the corresponding vertical mounting seat 703, and the mounting plate 710 and the second fixing frame 708 are connected by a first elastic member 711, and the circumferential side surface of the eccentric control part 702 is provided with relative concentric curved surfaces 712 and eccentric curved surfaces 713. When the concentric curved surface 712 on the eccentric control part 702 is vertically upward and fits with the inner wall of the bearing inner ring 3, the bearing inner ring 3 and the bearing outer ring 4 are in a concentric state (such as Fig.13As shown in FIG. 1 ), when the eccentric curved surface 713 on the eccentric control portion 702 is vertically upward and in contact with the inner wall of the bearing inner ring 3, the bearing inner ring 3 and the bearing outer ring 4 are in an eccentric state (as shown in FIG. 1 ). Fig.14 shown).

[0041] like Figure 1 As shown, the second motor is started to drive the vertical power shaft 608 to rotate clockwise, and the horizontal toggle frame 609 that rotates synchronously with the vertical power shaft 608 pushes the vertical moving rod 604 to slide to the right along the second limiting groove 109, and the horizontal support platform 602 is driven to move to the right under the action of the first fixed frame 605, and the assembly power wheel 601 that moves right synchronously with the horizontal support platform 602 gradually approaches the force-driven rotating wheel 701 on the right. In this process, since the entire eccentric control mechanism 7 is not subjected to external force, the entire eccentric control mechanism 7 does not move in this process. When the assembly power wheel 601 abuts against the force-driven rotating wheel 701 on the right, as the horizontal support platform 602 continues to move to the right, the assembly power wheel 601 pushes the force-driven rotating wheel 701 on the right to move right synchronously (the force-driven rotating wheel 701 on the left moves right synchronously), and in the process, the first elastic The member 711 is gradually compressed until the eccentric control part 702 on the right side just moves to the feeding port 107 on the right side (i.e., the eccentric control part 702 on the right side is coaxial with the bearing output tube 5 on the right side). At this time, the eccentric control part 702 on the left side just moves to the feeding port 107 in the center (i.e., the eccentric control part 702 on the left side is coaxial with the bearing ring delivery tube 2). Subsequently, a set of concentric bearing inner rings 3 and bearing outer rings 4 in the bearing ring delivery tube 2 are pushed into the material guide channel 102 from the corresponding feeding port 107 through the feeding push part 103. At this time, the eccentric control part 702 on the left side just supports a bearing inner ring 3, and the bearing outer ring 4 is just located inside the outer ring positioning frame on the left side (to ensure that the relative positions of the bearing inner ring 3 and the bearing outer ring 4 remain unchanged), thereby completing the loading operation of the bearing inner ring 3 and the bearing outer ring 4 on the eccentric control part 702 on the left side.

[0042] Next, the second motor drives the vertical power shaft 608 to rotate counterclockwise, so that the counterclockwise rotating horizontal toggle frame 609 pushes the vertical moving rod 604 to slide to the left along the second limiting groove 109. During this process, the first elastic member 711 gradually returns to its original state, and the eccentric control part 702 on the left side carries a set of bearing inner ring 3 and bearing outer ring 4 and gradually moves to the left. When the assembled power wheel 601 is separated from the force-driven rotating wheel 701 on the right side, the assembled power wheel 601 on the horizontal support platform 602 is continued to be controlled to move to the left. At this time, the entire eccentric control mechanism 7 does not move, and then the assembled power wheel 601 on the horizontal support platform 602 is continued to be controlled to move to the left. When the assembled power wheel 601 abuts against the force-driven rotating wheel 701 on the left, as the horizontal support platform 602 continues to move to the left, the assembled power wheel 601 pushes the force-driven rotating wheel 701 on the left side to move synchronously to the left. The first elastic member 711 is gradually stretched during the process until the eccentric control part 702 on the left just moves to the feeding port 107 on the left (i.e., a set of bearing inner ring 3 and bearing outer ring 4 on the eccentric control part 702 on the left are coaxial with the bearing output pipe 5 on the left). At this time, the eccentric control part 702 on the right just moves to the feeding port 107 in the center (i.e., the eccentric control part 702 on the right is coaxial with the bearing ring delivery pipe 2). Then, the assembled power wheel 601 is controlled to rotate clockwise, and the force-driven rotating wheel 701 on the left is driven to rotate counterclockwise under the action of friction force, until the eccentric control part 702 on the left, which rotates synchronously with the force-driven rotating wheel 701, completes a 180° rotation. At this time, the eccentric curved surface 713 on the eccentric control part 702 is vertically upward and fits the inner wall of the bearing inner ring 3, and the bearing inner ring 3 moves downward and deviates (such as Fig.14 As shown in the figure, a larger steel ball inlet is generated between the bearing inner ring 3 and the bearing outer ring 4, and the discharge port of the steel ball conveying pipe 104 on the left is just aligned with the steel ball inlet. A certain number of steel balls in the steel ball conveying pipe 104 on the left gradually fall from the steel ball inlet into the space between the bearing inner ring 3 and the bearing outer ring 4, and then the assembly power wheel 601 is controlled to rotate counterclockwise to complete the reset. At this time, the concentric curved surface 712 on the eccentric control part 702 is vertically upward and fits the inner wall of the bearing inner ring 3. The bearing inner ring 3 and the bearing outer ring 4 after the steel ball assembly are coaxial, and then the solenoid valve 112 on the gas discharge pipe 111 on the left is opened, and the assembled bearing is sprayed with the high-pressure airflow in the gas discharge pipe 111 on the left, so that the bearing slides out along the bearing output pipe 5 on the left to achieve collection.

[0043] During the above-mentioned steel ball assembly process, the next set of concentric bearing inner ring 3 and bearing outer ring 4 in the bearing ring conveying tube 2 is pushed into the material guide channel 102 from the corresponding feeding port 107 through the feeding pushing part 103. At this time, the eccentric control part 702 on the right side just supports a bearing inner ring 3, and the bearing outer ring 4 is just located inside the outer ring positioning frame on the right side (ensuring that the relative positions of the bearing inner ring 3 and the bearing outer ring 4 remain unchanged). Thus, the feeding operation of the bearing inner ring 3 and the bearing outer ring 4 on the eccentric control part 702 on the right side is completed, and then the vertical power shaft 608 is controlled to rotate clockwise, and the horizontal toggle frame 609 that rotates synchronously with the vertical power shaft 608 pushes the vertical moving rod 6 04 slides to the right along the second limiting groove 109 until a set of bearing inner ring 3 and bearing outer ring 4 on the eccentric control part 702 on the right side move to the position of the bearing output pipe 5 on the right side. At this time, the unloaded eccentric control part 702 on the left side just moves to the position of the bearing ring delivery pipe 2, and then controls the assembled power wheel 601 to rotate counterclockwise, and drives the right side driven wheel 701 to rotate clockwise under the action of friction, until the eccentric control part 702 on the right side that rotates synchronously with the driven wheel 701 completes a 180° rotation. At this time, the eccentric curved surface 713 on the eccentric control part 702 is vertically upward and fits the inner wall of the bearing inner ring 3, and the bearing inner ring 3 moves downward and deviates (such as Fig.14 As shown in the figure, a larger steel ball inlet is generated between the bearing inner ring 3 and the bearing outer ring 4, and the outlet of the steel ball conveying pipe 104 on the right is just aligned with the steel ball inlet. A certain number of steel balls in the steel ball conveying pipe 104 on the right gradually fall from the steel ball inlet into the space between the bearing inner ring 3 and the bearing outer ring 4. Then, the assembly power wheel 601 is controlled to rotate clockwise to complete the reset. At this time, the concentric curved surface 712 on the eccentric control part 702 is vertically upward and fits with the inner wall of the bearing inner ring 3. The bearing inner ring 3 and the bearing outer ring 4 after the steel ball assembly are coaxial. Then, the solenoid valve 112 on the gas discharge pipe 111 on the right is opened, and the assembled bearing is discharged through the high-pressure airflow in the gas discharge pipe 111 on the right. The bearing is blown so that it slides out along the bearing output pipe 5 on the right side for collection. In this process, the third set of concentric bearing inner ring 3 and bearing outer ring 4 in the bearing ring conveying pipe 2 are pushed into the material guide channel 102 from the corresponding feeding port 107 by the feeding pushing part 103 again. At this time, the eccentric control part 702 on the left side just supports a bearing inner ring 3, and the bearing outer ring 4 is just located inside the outer ring positioning frame on the left side (ensuring that the relative positions of the bearing inner ring 3 and the bearing outer ring 4 remain unchanged). Thus, the feeding operation of the bearing inner ring 3 and the bearing outer ring 4 on the eccentric control part 702 on the left side is completed, and the assembly work of each bearing inner ring 3 and the bearing outer ring 4 is continuously carried out in the same control method as mentioned above.

The bearing inner ring 3 pushed into the material guide channel 102 is just supported on the corresponding eccentric control part 702, and the bearing outer ring 4 is just entered into the corresponding outer ring positioning frame, thereby realizing the loading operation of a set of bearing inner ring 3 and bearing outer ring 4 on the eccentric control part 702.

[0045] In this embodiment of the present invention, an annular sealed cover 121 is fixedly installed on the top of the conveying guide frame 101, and the annular sealed cover 121 is arranged one by one with the steel ball conveying pipe 104. The annular sealed cover 121 is fixedly arranged on the top of the corresponding steel ball conveying pipe 104 and the two are connected. A conical storage hopper 122 connected thereto is fixedly installed on the top of the annular sealed cover 121, and a steel ball transfer part 123 is rotatably installed inside the annular sealed cover 121. A quantitative transfer cavity is opened on the side surface of the steel ball transfer part 123. The quantitative transfer cavity in the initial state is arranged vertically upward. At this time, a certain amount of material in the conical storage hopper 122 is The steel balls fall into the quantitative transfer chamber, and the number of steel balls in the quantitative transfer chamber is just the corresponding number of steel balls of the bearings that need to be assembled. One side of the steel ball transfer part 123 is connected to the second gear 124 through a fixed shaft; a third fixed frame 125 is fixedly provided on the side of the conveying guide frame 101 close to the second gear 124, and the third fixed frame 125 is arranged one-to-one with the conical storage hopper 122. A vertical meshing part 126 meshing with the corresponding second gear 124 is slidably provided on one side of the third fixed frame 125, and a second elastic member 127 connected to the vertical meshing part 126 is provided at the bottom of the third fixed frame 125.

[0046] When the eccentric control part 702 on the left side just moves to align with the bearing output tube 5 on the left side, the first gear 707 on the left side moves horizontally to mesh with the vertical meshing part 126 on the left side. At this time, the assembled power wheel 601 and the force-driven rotating wheel 701 on the left side are tightly pressed together. In the process of controlling the assembled power wheel 601 to rotate clockwise, the force-driven rotating wheel 701 on the left side is driven to rotate counterclockwise. The first gear 707 on the left side rotates counterclockwise synchronously with the corresponding force-driven rotating wheel 701. The counterclockwise rotating first gear 707 drives the vertical meshing part 126 on the left side to move downward and stretch the second elastic member 127 on the left side. The vertical meshing part 126 moving downward drives the second gear 124 on the left side to rotate counterclockwise. When the eccentric control part 702 on the left side just completes a 180° rotation, the second gear 124 on the left side also just completes a 180° rotation (the steel ball transfer part 123 on the left side just completes a 180° rotation). At this time, the quantitative transfer chamber on the steel ball transfer part 123 is set vertically downward, and then a certain number of steel balls in the quantitative transfer chamber slide along the steel ball conveying pipe 104 on the left side to the space between the corresponding bearing inner ring 3 and the bearing outer ring 4, thereby realizing the preliminary assembly of the bearing. After the assembly is completed, the power distribution wheel 601 is controlled to rotate counterclockwise to complete the reset. At this time, the quantitative transfer chamber on the steel ball transfer part 123 on the left side is reset synchronously (that is, the quantitative transfer chamber on the steel ball transfer part 123 on the left side is set vertically upward).

[0047] When the eccentric control part 702 on the right side just moves to align with the bearing output tube 5 on the right side, the first gear 707 on the right side moves horizontally to mesh with the vertical meshing part 126 on the right side. At this time, the assembled power wheel 601 and the force-driven rotating wheel 701 on the right side are tightly pressed together. When the assembled power wheel 601 is controlled to rotate counterclockwise, the force-driven rotating wheel 701 on the right side is driven to rotate clockwise. The first gear 707 on the right side rotates clockwise synchronously with the corresponding force-driven rotating wheel 701. The clockwise rotating first gear 707 drives the vertical meshing part 126 on the right side to move downward and stretch the second elastic member 127 on the right side. The vertical meshing part 126 moving downward drives the second gear 124 on the right side to rotate clockwise. When the eccentric control part 702 on the right side just completes a 180° rotation, the second gear 124 on the right side also just completes a 180° rotation (the steel ball transfer part 123 on the right side just completes a 180° rotation). At this time, the quantitative transfer chamber on the steel ball transfer part 123 is set vertically downward, and then a certain number of steel balls in the quantitative transfer chamber slide along the steel ball conveying pipe 104 on the right side to the space between the corresponding bearing inner ring 3 and the bearing outer ring 4, thereby realizing the preliminary assembly of the bearing. After the assembly is completed, the power distribution wheel 601 is controlled to rotate clockwise to complete the reset. At this time, the quantitative transfer chamber on the steel ball transfer part 123 on the right side is reset synchronously (that is, the quantitative transfer chamber on the steel ball transfer part 123 on the right side is set vertically upward).
