Description

Technical Field

[0001] This invention relates to the field of bearing press-fitting technology, specifically to an automated press-fitting device for motorcycle bearing processing. Background Technology

[0002] Against the backdrop of the booming development of intelligent manufacturing technology and the widespread application of industrial automation control and integrated equipment in China, the production process of the motorcycle manufacturing industry continues to innovate. For transmission bearings in key components such as motorcycle engines, the precision and processing efficiency of press-fitting equipment have become core elements for enterprises to improve product quality and expand production capacity. In today's fiercely competitive environment, enterprises have never stopped pursuing high-precision, mass production of bearing components. As the starting point of the press-fitting process, the efficiency and accuracy of the feeding stage directly affect the operating rhythm of the entire production line.

[0003] For details, please refer to the bearing pressing device for the motor rotor assembly line disclosed in patent application number 2012203218527. In terms of bearing feeding during rotor pressing, it is still difficult to achieve automated operation. After each pressing process is completed, it still relies on manual placement of the bearing in the designated position, which seriously restricts production efficiency and cannot match the high-speed production line. Once there is a slight deviation in the feeding process, the subsequent pressing process can only be interrupted. The equipment is frequently stopped for adjustment, which not only seriously affects the continuity of production, but also greatly increases labor and time costs. Summary of the Invention

[0004] The purpose of this invention is to provide an automated press-fitting device for motorcycle bearing processing, which solves the problems mentioned in the background art above.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automated pressing device for motorcycle bearing processing, comprising a base, a housing and a frame plate fixedly installed on the top of the base, a platform for pressing workpieces and a slide table for continuous feeding respectively provided on both sides of the frame plate, a steering feeding component for steering and conveying workpieces provided on the top of the base and inside the housing, and a pressing assembly for pressing workpieces provided on the top of the platform.

[0006] Furthermore, fixed seats are fixedly connected to both sides of the top of the base, and multiple guide slide rods and a fixed plate are fixedly connected between the two fixed seats. The slide table slides horizontally on the outside of the guide slide rods through a through groove in the side wall. A drive frame is fixedly connected to the bottom of the slide table, and an I-shaped slide frame is fixedly connected to the bottom of the drive frame. An I-shaped guide rail is fixedly connected to the top of the base for directional sliding of the I-shaped slide frame.

[0007] Furthermore, three I-shaped guide rails are fixedly connected to the top of the base, and an I-shaped sliding frame is slidably connected to the top of the I-shaped guide rails.

[0008] The steering and feeding component includes two swing frames one and one swing frame two. The top of the two I-shaped sliding frames one is fixedly connected to the swing frame one, and the top of one of the I-shaped sliding frames one is fixedly connected to the swing frame two. The side walls of the two swing frames one are respectively fixedly connected to push plate one and push plate two. The side wall of the swing frame two is fixedly connected to a drive rail through a connecting frame. The drive rail cooperates with the drive frame.

[0009] Furthermore, two supports are fixedly connected to the top of the base and to the outside of the three I-shaped guide rails. A central shaft is movably connected between the two supports via bearings. An eccentric rotor I and an eccentric rotor II, which cooperate with a pendulum frame I and a pendulum frame II, are sleeved and fixed on the outside of the central shaft. A motor for driving the rotation of the central shaft is fixedly installed on the outer wall of the support.

[0010] Furthermore, a support frame is provided above the slide table, and the two ends of the support frame are fixedly connected to the top of the fixed plate and the top of the frame plate, respectively. Three limiting blocks are fixedly connected at equal intervals on the top of the slide table, and the spacing between adjacent limiting blocks forms a placement groove for placing workpieces. A material frame for placing workpieces is fixedly installed on the top of the support frame, and a material groove for workpieces to pass through is provided at the connection between the material frame and the support frame.

[0011] Furthermore, a tray is provided on the top of the frame, and electric arc-shaped grippers are symmetrically installed on the top of the tray. Two electric rotating frames are fixedly installed on the top of the platform, and one end of the tray is fixedly connected to the rotating sleeve inside the electric rotating frame.

[0012] Furthermore, the top of the platform has two pressing grooves, and a material carrier plate is slidably connected in the pressing grooves. A horizontal plate is fixedly connected to the side wall of the frame plate and located below the platform. Two electric push rods are fixedly connected to the top of the horizontal plate, and the top of the electric push rods is fixedly connected to the bottom of the material carrier plate.

[0013] Furthermore, the pressing assembly consists of two lifting push rods and two pressing blocks. The lifting push rods are fixedly installed on the bottom of the inner wall of the mounting frame at the top of the platform, and the pressing blocks are fixedly connected to the bottom end of the lifting push rods.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] In the bearing feeding stage, a steering feeding component is set up. Eccentric rotor one and eccentric rotor two are installed on the central shaft with a specific phase difference. Under the drive of the motor, based on the motion characteristics of the eccentric wheel mechanism, the rotational motion of the central shaft is converted into the linear reciprocating motion of swing frame one and swing frame two. Swing frame two controls the slide table to make periodic horizontal linear motion along the guide slide rod through the transmission between the drive rail and the drive frame.

[0016] The material storage and feeding system, consisting of the support frame and the material frame, combined with the equally spaced placement slots formed by the sliding table limit block, utilizes the principle of spatial misalignment to achieve continuous supply of bearing materials. At the same time, the two swing frames drive the push plate one and push plate two to move in opposite directions synchronously. By alternating pushing, the empty stroke in the traditional feeding process is eliminated, which significantly improves the feeding efficiency and achieves seamless material conveying.

[0017] In the press-fitting operation of bearings and bearing housings, the electric arc-shaped gripper precisely positions and grasps the bearing, which can quickly complete the bearing posture adjustment and ensure accurate alignment with the bearing housing in the press-fitting groove. In conjunction with the 180-degree rotation mechanism of the electric rotating frame, the pressing assembly can achieve high-precision press-fitting of the bearing and bearing housing.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1: As Figures 1-10 As shown, an automated pressing equipment for processing motorcycle bearings includes a base 1, an organic cover 2 and a frame plate 3 fixedly installed on the top of the base 1, a platform 4 for pressing workpieces and a slide table 5 for continuous feeding are respectively provided on both sides of the frame plate 3, a steering feeding component for steering and conveying workpieces is provided on the top of the base 1 and inside the organic cover 2, and a pressing assembly for pressing workpieces is provided on the top of the platform 4.

[0032] The top two sides of the base 1 are fixedly connected to fixed seats 6. Multiple guide slide rods 7 and a fixed plate are fixedly connected between the two fixed seats 6. The slide table 5 has a through groove through the side wall and slides horizontally on the outside of the guide slide rods 7. The bottom of the slide table 5 is fixedly connected to a drive frame 8. The bottom of the drive frame 8 is fixedly connected to an I-shaped slide frame 2. The top of the base 1 is fixedly connected to an I-shaped guide rail 2 902 for directional sliding of the I-shaped slide frame 1.

[0033] The top of the base 1 is fixedly connected to three I-shaped guide rails 901, and the top of the I-shaped guide rails 901 is slidably connected to an I-shaped slide frame 1. The turning and feeding component includes two swing frames 101 and one swing frame 2 102, wherein the top of the two I-shaped slide frames 1 is fixedly connected to the swing frame 101.

[0034] One of the I-shaped sliding frames is fixedly connected to the top of a swing frame 102. The side walls of the two swing frames 101 are respectively fixedly connected to push plate 103 and push plate 2 104. The side wall of the swing frame 2 102 is fixedly connected to a drive rail 105 through a connecting frame. The drive rail 105 cooperates with the drive frame 8.

[0035] Two supports are fixedly connected to the top of the base 1 and outside the three I-shaped guide rails 901. A central shaft 14 is movably connected between the two supports via bearings. An eccentric rotor 15 and an eccentric rotor 16 that cooperate with a pendulum frame 101 and a pendulum frame 102 are sleeved and fixed on the outside of the central shaft 14. It should be noted that the inner wall spacing of the pendulum frame 101 is larger than that of the pendulum frame 102, and the diameter of the eccentric rotor 15 is larger than that of the eccentric rotor 16. A motor for driving the rotation of the central shaft 14 is fixedly installed on the outer wall of the support.

[0036] Eccentric rotors 15 and 16, respectively installed in two pendulum frames 101 and one pendulum frame 102, are positioned at the central axis 14. Figure 3 As shown, when the central shaft 14 drives the eccentric rotor 15 and the eccentric rotor 16 to rotate synchronously, the two pendulum frames 101 move synchronously back and forth and in opposite directions under the drive of the two corresponding eccentric rotors 15.

[0037] Push plate 103 and push plate 2 104 move synchronously and alternately in opposite directions. Push plate 103 or push plate 2 104 pushes the bearing in the corresponding placement slot in a cycle. When the two eccentric rotors 15 rotate to the initial position, push plate 103 or push plate 2 104 is pulled out from the corresponding placement slot to avoid interfering with the normal movement of slide table 5 and limit block 12.

[0038] A support frame 11 is provided above the slide table 5. The two ends of the support frame 11 are fixedly connected to the top of the fixed plate and the top of the frame plate 3, respectively. Three limiting blocks 12 are fixedly connected to the top of the slide table 5 in an equally spaced manner. The spacing between adjacent limiting blocks 12 forms a placement groove for placing workpieces.

[0039] A material frame 13 for placing workpieces is fixedly installed on the top of the support frame 11. A material groove for workpieces to pass through is opened at the connection between the material frame 13 and the support frame 11. The material frame 13 is used to stack the workpieces required for pressing motorcycle bearings. Through the gap formed between adjacent limit blocks 12 and the material groove, the workpieces in the material frame 13 can be continuously and alternately fed.

[0040] Example 2: A tray 17 is provided on the top of the frame plate 3. Electric arc-shaped grippers 18 are symmetrically installed on the top of the tray 17. Two electric rotating frames 19 are fixedly installed on the top of the platform 4. One end of the tray 17 is fixedly connected to the rotating sleeve inside the electric rotating frame 19. The electric arc-shaped grippers 18 and the electric rotating frame 19 are existing equipment. The electric arc-shaped grippers 18 are used to clamp the workpiece and drive the electric rotating frame 19 to rotate the workpiece 180 degrees through the tray 17 and the electric arc-shaped grippers 18.

[0041] The top of platform 4 has two pressing slots for placing bearing seats. The workpiece mentioned above refers to the bearing. The bearing is rotated 180 degrees by the electric rotating frame 19 so that it fits against the top of the bearing seat in the pressing slot. It should be explained here that the size of the pressing slot matches the size of the current bearing seat. A material carrier plate 20 is slidably connected in the pressing slot.

[0042] A horizontal plate is fixedly connected to the side wall of the frame plate 3 and below the platform 4. Two electric push rods 21 are fixedly connected to the top of the horizontal plate. The top of the electric push rods 21 is fixedly connected to the bottom of the material plate 20. The pressing assembly consists of two lifting push rods 22 and two pressing blocks 23. The lifting push rods 22 are fixedly installed on the bottom of the inner wall of the mounting frame at the top of the platform 4, and the pressing blocks 23 are fixedly connected to the bottom of the lifting push rods 22.

[0043] As can be seen from Embodiment 1 and Embodiment 2, the working principle of the present invention is as follows:

[0044] The bearings are neatly stacked inside the material frame 13. The motor drives the central shaft 14 and the eccentric rotor 15 and eccentric rotor 2 16 on its outer side to rotate synchronously. The eccentric rotor 2 16 drives the swing frame 2 102 to slide in a direction outside the I-shaped guide rail 1 901. During the movement, the swing frame 2 102 pushes the drive rail 105, thereby causing the drive frame 8 that cooperates with the drive rail 105 to be passively driven. Under the action of the drive rail 105, the drive frame 8 further drives the I-shaped slide frame 2 to move on the top of the I-shaped guide rail 2 902, and further drives the slide table 5 connected to the top of the drive frame 8 to move synchronously.

[0045] The slide table 5 drives the three limiting blocks 12 at the top to move synchronously and pass under the support frame 11. When the placement groove between two adjacent limiting blocks 12 is connected to the material groove, the bearing located in the material frame 13 falls into the placement groove. The slide table 5 continues to move until the bearing is pushed out from under the support frame 11.

[0046] Then, the corresponding push plate 103 is used to push the bearing in the placement slot to the top of the tray 17. The electric arc gripper 18 positions and grips the current bearing and adjusts its posture. The electric rotating frame 19 is used to rotate the bearing 180 degrees until the bearing contacts the top of the bearing seat in the pressing slot. The electric arc gripper 18 releases the grip on the bearing and returns to the initial position to facilitate the transport of the next bearing.

[0047] When the slide table 5 pushes the bearing out from under the support frame 11, another placement slot is also connected to the material trough, causing the bearing in the material frame 13 to fall into the placement slot. After the previous bearing is pushed to the top of the tray 17, the swing frame 2 102 moves in the opposite direction, and the cooperation of the drive frame 8 and the drive rail 105 causes the slide table 5 to move in the opposite direction synchronously. The empty placement slot at the top of the slide table 5 enters under the support frame 11 again until it is connected to the material trough, waiting for the next bearing to fall.

[0048] Another placement slot containing the bearing is pushed out from the other side of the support frame 11. Then, the corresponding push plate 104 pushes the bearing in the placement slot to the top of another tray 17. The electric arc gripper 18 clamps the current bearing and the electric rotating frame 19 rotates the bearing 180 degrees until the bearing contacts the top of the bearing seat in the press-fit slot.

[0049] The electric arc gripper 18 releases the gripper on the bearing and returns to the initial position, facilitating the transport of the next bearing. Through the cooperation of the swing frame 2 102 and the eccentric rotor 2 16, and the cooperation of the drive frame 8 and the drive rail 105, the horizontal reciprocating movement of the slide table 5 is realized. Furthermore, the mutual cooperation of the three limit blocks 12 is used to realize the alternating feeding of bearings in different directions.

[0050] Before the bearing is loaded, the bearing housing is placed in the corresponding pressing groove. Then, the bearing is placed on the designated bearing housing using the tray 17 and the electric arc gripper 18. The lifting push rod 22 drives the pressing block 23 to descend until the pressing of the bearing and bearing housing is completed. After the pressing is completed, the electric push rod 21 pushes the material plate 20 to rise and pushes out the pressed bearing and bearing housing for easy removal.

[0051] The preferred embodiments of the present invention disclosed above are merely illustrative of the invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
