Description

Technical Field

[0001] This application relates to the field of automated production technology of brushless motors, and in particular to a fully automatic press-fitting machine for a combination of oil-impregnated bearings and ball bearings. Background Technology

[0002] Bearing press-fitting is a crucial step in the machinery manufacturing industry, widely used in automotive, aerospace, and home appliance sectors. Traditional bearing press-fitting equipment relies primarily on manual operation or simple semi-automated machines. While these machines can meet basic production needs, they suffer from significant shortcomings in efficiency, precision, and consistency. With the continuous improvement of industrial automation, the market demand for efficient and high-precision bearing press-fitting equipment is growing. Fully automated bearing press-fitting machines have emerged, not only increasing production efficiency but also significantly improving product quality and stability, bringing substantial economic benefits to enterprises.

[0003] Currently, existing bearing press-fitting equipment still faces many challenges in practical applications. Firstly, there's the issue of positioning accuracy. Due to the relatively simple mechanical structure of traditional equipment, achieving high-precision positioning is difficult, leading to misalignment or displacement during the press-fitting process. Secondly, the level of automation is low; many machines still require manual intervention, especially in bearing loading, increasing labor intensity and production costs. These problems make the development of a high-precision, fully automated, and highly flexible bearing press-fitting machine an urgent need. Summary of the Invention

[0004] The purpose of this application is to overcome the above-mentioned technical problems and provide a fully automatic press-fitting machine for oil-impregnated bearings and ball bearings, which can realize fully automatic press-fitting of bearings to improve production efficiency and accuracy.

[0005] This application provides a fully automatic press-fitting machine for a combination of oil-impregnated bearings and ball bearings, using the following solution:

[0006] A fully automatic press-fitting machine for oil-impregnated bearings and ball bearings includes: a machine base; a bearing placement platform disposed on the machine base, a placement component disposed on the bearing placement platform, a first receiving groove provided at the end of the placement component away from the machine base, and a first through hole axially extending through the first receiving groove. A through-hole component opposite to the placement component is also disposed on the bearing placement platform, the through-hole component having a second through hole extending through the first receiving groove and the first through hole. The end of the through-hole component away from the placement component is the target position for moving and placing the oil-impregnated bearing, and the first receiving groove is used for accommodating the ball bearing. The following components are included: a push pin assembly, one end of which is configured as a push pin to penetrate and abut against one end face of the oil-impregnated bearing, and to drive the oil-impregnated bearing to move axially in the second through hole and the first through hole to abut against the ball bearing; a pressing assembly, located on the machine base above the bearing placement platform, and having a pressing member relative to the first receiving groove, the pressing member being used to abut against and press down the ball bearing to press the oil-impregnated bearing and the ball bearing together; an oil-impregnated bearing feeding mechanism, located on the machine base, for moving the oil-impregnated bearing to the target position; and a ball bearing feeding mechanism, located on the machine base, for moving the ball bearing into the first receiving groove.

[0007] By adopting the above technical solution, a highly efficient and precise bearing assembly process can be achieved. Specific effects are as follows: By setting up oil-impregnated bearing and ball bearing feeding mechanisms, automatic feeding of both bearings is realized, reducing manual intervention and improving production efficiency. The design of the placement components and through-hole components on the bearing placement table ensures precise alignment of the oil-impregnated and ball bearings, guaranteeing assembly accuracy. The design of the ejector pin assembly allows the oil-impregnated bearing to be smoothly pushed and contacted with the ball bearing, while the pressing component of the pressing assembly effectively completes the pressing of both, making the entire process simple and reliable. This equipment is suitable for assembling various types of bearings, and it has significant advantages, especially for applications requiring high-precision assembly.

[0008] Optionally, the oil-impregnated bearing feeding mechanism includes: a first feeding assembly, comprising a first feeding box, a first swing output component, and a first vibration component, wherein the first feeding box is used to accommodate the oil-impregnated bearing, the first swing output component and the first vibration component are disposed within the first feeding box, and the first swing output component is used to actuate the oil-impregnated bearing for output; a first output channel, connected to the first feeding box, which outputs the oil-impregnated bearing sequentially in conjunction with the vibration of the first vibration component; and a first moving assembly, comprising a first driving component and a magnetic suction component, wherein the first driving component is fixed on the machine base, one end of the magnetic suction component is connected to the first driving component, and the other end is used to magnetically suction the oil-impregnated bearing to place the oil-impregnated bearing at the target position.

[0009] By adopting the above technical solutions, the oil-impregnated bearing feeding mechanism can achieve a highly efficient and stable automatic feeding process. Specifically: the first swing output component and the first vibration component in the first feeding assembly work together to ensure the orderly arrangement and smooth output of the oil-impregnated bearings in the first feeding box, improving the reliability and efficiency of feeding. The design of the first output channel allows the oil-impregnated bearings to be smoothly transmitted sequentially under vibration, further ensuring the continuity of feeding. The first moving component uses magnetic attraction to precisely move the oil-impregnated bearings to the target position, which not only improves positioning accuracy but also reduces mechanical wear and extends the equipment life.

[0010] Optionally, the oil-impregnated bearing feeding mechanism includes a material-taking component, comprising a second driving member and a material-taking member. The second driving member is disposed on the machine base, and the telescopic end away from the machine base is connected to the material-taking member. A second receiving groove is provided on the side of the material-taking member for docking with the end of the first output channel away from the first feeding box to accommodate the oil-impregnated bearing output from the first output channel. The material-taking member is used to drive the oil-impregnated bearing to the magnetic position of the magnetic attractor, so that the magnetic attractor can perform magnetic attraction movement.

[0011] By adopting the above technical solution, the material handling component can accurately retrieve the oil-impregnated bearing from the first output channel and precisely move it to the magnetic suction position of the magnetic suction component, ensuring that the oil-impregnated bearing moves smoothly to the target position, thus improving the feeding accuracy and efficiency. Meanwhile, the design of the second drive component and the material handling component makes the entire process more stable and reliable, reduces manual intervention, and improves the degree of automation.

[0012] Optionally, the ball bearing feeding mechanism includes: a second feeding assembly, comprising a second feeding box, a second swing output component, and a second vibration component, wherein the second feeding box is used to accommodate the ball bearing, the second swing output component and the second vibration component are disposed within the second feeding box, and the second swing output component is used to actuate the ball bearing for output; a second output channel, connected to the second feeding box, which sequentially outputs the ball bearing in coordination with the vibration of the second vibration component; and a second moving assembly, comprising a third driving component and a clamping component, wherein the third driving component is fixed to the machine base, one end of the clamping component is fixed to the third driving component, and the other end is used to movably clamp the ball bearing to place the ball bearing in the first accommodating groove.

[0013] By adopting the above technical solution, the ball bearing feeding mechanism can achieve automated feeding, improving production efficiency. Specifically, the second feeding component, through the coordinated action of the second swing output component and the second vibration component, ensures that the ball bearings are output to the second output channel in an orderly and stable manner. The design of the second output channel allows the ball bearings to be smoothly transported to the designated position. The second moving component, using the cooperation of the third driving component and the clamping component, precisely places the ball bearings in the first receiving slot, ensuring the accuracy and reliability of assembly.

[0014] Optionally, it also includes: a material blocking assembly, including a first support frame, a fourth drive member and an abutment member, wherein the first support frame is disposed on the machine base, the fourth drive member is disposed on the first support frame, and the telescopic end is connected to the abutment member for driving the abutment member to rise and fall above the second output channel for movably abutting the subsequent ball bearing.

[0015] By adopting the above technical solution, the material blocking assembly can effectively control the conveying process of the ball bearings, ensuring that each ball bearing enters the subsequent process in an orderly manner. Specifically, the first support frame provides a stable mounting base for the fourth drive component, which drives the abutment component to move up and down above the second output channel, thereby achieving precise blocking or release of the ball bearings. This design not only improves the automation level of the equipment but also avoids blockage or misalignment of the ball bearings during conveying, ensuring production efficiency and product quality.

[0016] Optionally, the bearing placement platform is a rotary placement platform, and multiple placement components and multiple through-hole components are provided on the bearing placement platform, with each placement component corresponding to one of the through-hole components.

[0017] By adopting the above technical solutions, continuous multi-station operation can be achieved, improving production efficiency and equipment utilization. Specifically, the rotary placement table design allows multiple placement components to be reused, thereby realizing a continuous and efficient bearing press-fitting process for oil-impregnated bearings and ball bearings. In addition, the multi-station design reduces equipment idle time, further increasing production speed.

[0018] Optionally, the ejector pin is provided with a shoulder for abutting against one end face of the oil-impregnated bearing.

[0019] By adopting the above technical solution, the shoulder design on the ejector pin can ensure that the oil-impregnated bearing remains stable when it is pushed, preventing it from shifting or tilting during axial movement, thereby ensuring that the oil-impregnated bearing can accurately contact the ball bearing, improving the pressing accuracy and reliability.

[0020] Optionally, the pressing assembly includes: a second support frame disposed on the machine base; a fifth driving member disposed on the second support frame, with its telescopic end passing through the second support frame; a limiting member, one end of which is sleeved on the telescopic end of the fifth driving member, and the other end of which passes through the second support frame, with a corresponding limiting hole provided on the second support frame; and a pressing member connected to the telescopic end of the fifth driving member, located at the end of the limiting member away from the second support frame.

[0021] By adopting the above technical solution, the pressing assembly can achieve precise pressing, ensuring a tight fit between the oil-impregnated bearing and the ball bearing. Specifically, the second support frame provides a stable support structure, ensuring stability during the pressing process; the telescopic movement of the fifth drive component enables the up-and-down movement of the pressing component, thereby applying pressure to the ball bearing; the design of the limiting component ensures accurate positioning of the pressing component during movement, preventing offset or overpressure, and improving pressing accuracy and reliability.

[0022] Optionally, the oil-impregnated bearing feeding mechanism further includes: a first detection component, including a first sensor and a first controller. The first sensor is disposed at the end of the first output channel and is used to detect the position of the oil-impregnated bearing. The first controller is electrically connected to the first sensor and the first drive component and is used to control the action of the first drive component.

[0023] By adopting the above technical solution, precise detection and control of the oil-impregnated bearing position can be achieved, ensuring that the oil-impregnated bearing accurately enters the second receiving groove for magnetic adsorption, thus improving the reliability and efficiency of feeding. Simultaneously, the coordinated operation of the first sensor and the first controller enables automated control, reducing the need for manual intervention and enhancing the stability and continuity of the production process.

[0024] Optionally, the ball bearing feeding mechanism further includes a second detection component, comprising a second sensor and a second controller. The second sensor is disposed at the end of the second output channel and is used to detect the position of the ball bearing. The second controller is electrically connected to the second sensor and the third drive component and is used to control the action of the third drive component.

[0025] By adopting the above technical solution, the second sensor can detect the position of the ball bearing at the end of the second output channel in real time, ensuring that the ball bearing accurately reaches the designated position for the clamping component to clamp and move, thereby improving the accuracy and reliability of ball bearing loading. Simultaneously, the second controller, based on the information fed back by the second sensor, precisely controls the movement of the third drive component, enabling the clamping component to accurately and quickly clamp the ball bearing and place it into the first receiving slot, further improving the automation level and work efficiency of the entire loading process.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

Detailed Implementation

[0042] The terminology used in the following embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” and “this” are intended to include the plural expressions as well, unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used in this application refers to and includes any or all possible combinations of one or more of the listed items.

[0043] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature, and in the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0044] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0045] See Figure 1 and Figure 2 This application discloses a fully automatic oil-impregnated bearing and ball bearing combination press-fitting machine, which is used to combine and press-fit oil-impregnated bearings and ball bearings to serve as stator press-fitting bearings for brushless motors. The press-fitting machine includes: a machine base 10 and a bearing placement platform 20, a pin assembly 30, a pressing assembly 40, an oil-impregnated bearing feeding mechanism 50, and a ball bearing feeding mechanism 60 disposed on the machine base 10. Through the coordinated work of these components, a high-precision, fully automated, and highly flexible bearing press-fitting process is achieved.

[0046] See Figure 2 and Figure 3 The bearing placement table 20 is provided with multiple placement components 21. Each placement component 21 has a first receiving groove 211 at the end away from the machine base 10 for accommodating ball bearings, and an axially provided first through hole (not shown in the figure). The bearing placement table 20 can rotate clockwise or counterclockwise. Correspondingly, a rotary motor (not shown in the figure) is provided at the lower end of the bearing placement table 20, so that multiple placement components 21 can enter the working position in sequence, which is below the pressing assembly 40, thereby completing the pressing operation of multiple bearings in one complete rotation cycle.

[0047] See Figure 3 On the bearing placement platform 20, there is also a through hole 22 relative to the placement member 21. The through hole 22 is provided with a second through hole 221 that passes through the first receiving groove 211 and the first through hole. The end of the through hole 22 away from the placement member 21 is the target position where the oil-impregnated bearing is moved and placed by the oil-impregnated bearing feeding mechanism 50, so that the ejector pin assembly 30 can be sleeved on it. The ejector pin assembly 30 lifts the oil-impregnated bearing and passes through the second through hole 221 and the first through hole in sequence to abut against the ball bearing.

[0048] See Figure 4 and Figure 5 One end of the ejector pin assembly 30 is configured as an ejector pin 31, which has a shoulder 311, resulting in different overall radii. The end with the smaller radius is used to penetrate and abut against one end face of the oil-impregnated bearing, pushing the oil-impregnated bearing to move axially along the second through hole 221 and the first through hole, and finally abut against the ball bearing. In addition, the ejector pin assembly 30 is also provided with a driving component to drive the ejector pin 31 to move up and down, so that the ejector pin 31 lifts the oil-impregnated bearing to abut against the ball bearing.

[0049] See Figure 1 and Figure 2The pressing assembly 40 is mounted on the machine base 10, located above the bearing placement platform 20, and has a pressing member 41 positioned relative to the first receiving groove 211. The pressing member 41 is used to press the ball bearing placed in the first receiving groove 211 downwards, while the ejector pin assembly 30 drives the oil-impregnated bearing to move upwards through the second through hole 221 and the first through hole, thereby ensuring that the oil-impregnated bearing and the ball bearing are tightly engaged. The pressing assembly 40 can be driven by a cylinder, hydraulic cylinder, or other driving methods to ensure uniform distribution of pressing force and avoid damage caused by excessive local force.

[0050] The pressing assembly 40 also includes a second support frame 42, a fifth driving component 43, and a limiting component 44. The second support frame 42 is mounted on the machine base 10, and its structure is as follows: Figure 2 As shown in the diagram, the fifth driving component 43 is a cylinder, mounted on the second support frame 42, with its telescopic end passing through the second support frame 42 and sequentially connected to a limiting component 44 and a pressing component 41. One end of the limiting component 44 is sleeved on the telescopic end of the fifth driving component 43, and the other end passes through the second support frame 42. The second support frame 42 is provided with corresponding limiting holes to ensure that the pressing component 41 does not shift when the limiting component 44 moves with the fifth driving component 43. The pressing component 41 is used to abut against the surface of the ball bearing and moves up and down with the drive of the fifth driving component 43. During the descent, it presses down on the ball bearing to press it into the oil-impregnated bearing.

[0051] See Figure 6 and Figure 7 The oil-impregnated bearing feeding mechanism 50 includes a first feeding component 51, a first output channel 52, and a first moving component 53. The first feeding component 51 is used to sequentially feed the oil-impregnated bearing into the first output channel 52. After the first moving component 53 is taken out and moved to the target position (the end of the through hole 22 away from the placement component 21), the ejector pin 31 is fitted. The ejector pin 31 then drives the oil-impregnated bearing to abut against the ball bearing and cooperates with the pressing component 40 to press it together.

[0052] The first feeding assembly 51 includes a first feeding box 511, a first swing output component (not shown in the figure), and a first vibration component (not shown in the figure). The first feeding box 511 stores a large number of oil-impregnated bearings. The first swing output component and the first vibration component are disposed within the first feeding box 511. The first swing output component is a sweeping blade located above the first output channel 52 (the first output channel 52 extends into the first feeding box 511), used to sweep out oil-impregnated bearings with incorrect orientation from the first output channel 52. The first vibration component can be understood as a vibrating disc, used to sequentially output oil-impregnated bearings into the first output channel 52, automatically screening the output direction of the oil-impregnated bearings and causing them to move and be output along the first output channel 52. It should be noted that in this embodiment, the structure of the first swing output component and the first vibration component is not limited, as long as it can achieve the output of oil-impregnated bearings in a certain direction.

[0053] Furthermore, to achieve precise detection and control of the position of the oil-impregnated bearing, this embodiment includes a first detection component (not shown in the figure). The first detection component includes a first sensor and a first controller. The first sensor is located at the end of the first output channel 52 and is used to detect the position of the oil-impregnated bearing output. The first controller is electrically connected to the first sensor and the first drive component 531 and is used to control the action of the first drive component 531 to improve the reliability and efficiency of material feeding. Simultaneously, through the coordinated work of the first sensor and the first controller, automated control is achieved, reducing the need for manual intervention and improving the stability and continuity of the production process.

[0054] See Figure 8 The first moving component 53 includes a first driving component 531 and a magnetic attractor 532. The first driving component 531 can be a linear guide slide cylinder, with one end fixed to the machine base 10 and the other end connected to the magnetic attractor 532. One end of the magnetic attractor 532 is connected to the first driving component 531, and the other end is used to magnetically attract the oil-impregnated bearing, so as to place the oil-impregnated bearing in the target position, so that the ejector pin 31 provided at one end of the ejector pin assembly 30 can pass through and abut against it. It should be noted that the magnetic attractor 532 is an electromagnet, which achieves the magnetic attraction effect when energized, and the corresponding oil-impregnated bearing is made of metal.

[0055] Furthermore, the oil-impregnated bearing feeding mechanism 50 also includes a material-taking component 54, which includes a second driving component 541 and a material-taking component 542. The second driving component 541 is a cylinder, which is mounted on the machine base 10, and its telescopic end, which is away from the machine base 10, is connected to the material-taking component 542. The material-taking component 542 has a second receiving groove 5 on its side, which is used to connect to the end of the first output channel 52 away from the first feeding box 511, so as to receive the oil-impregnated bearing output from the first output channel 52.

[0056] The material taking part 542 is driven by the second driving part 541 to move up and down, so as to drive the oil-impregnated bearing to the magnetic position of the magnetic suction part 532, so that the magnetic suction part 532 can move magnetically to move the oil-impregnated bearing to the target position for the ejector pin to pass through.

[0057] See Figure 9 The ball bearing feeding mechanism 60 includes a second feeding component 61, a second output channel 62, and a second moving component 63. The second feeding component 61 is used to sequentially feed the ball bearings into the second output channel 62. After the second moving component 63 takes them out, they are moved into the first receiving groove 211 for the pressing component 40 to press them. At the same time, the ejector pin 31 drives the oil-impregnated bearing to move to the target position in advance to abut against the ball bearing, thereby realizing the pressing.

[0058] The second feeding assembly 61 includes a second feeding box 611, a second oscillating output component (not shown in the figure), and a second vibrating component (not shown in the figure). The second feeding box 611 stores a large number of ball bearings. The second oscillating output component and the second vibrating component are disposed within the second feeding box 611. The second oscillating output component is a sweeping blade located above the first output channel 52 (the second output channel 62 extends into the second feeding box 611), used to sweep out ball bearings with incorrect orientation from the second output channel 62. The second vibrating component can be understood as a vibrating disc, used to sequentially output ball bearings into the second output channel 62, automatically screening the output direction of the ball bearings and causing them to move and be output along the second output channel 62. It should be noted that in this embodiment, the first feeding assembly 51 and the second feeding assembly 61 adopt the same structure. In addition, the structure of the second oscillating output component and the second vibrating component is not limited, as long as it can achieve the output of ball bearings in a certain direction.

[0059] See Figure 10 The second moving component 63 includes a third driving member 631 and a clamping member 6311. The third driving member 631 can be a cylinder, with one end fixed on the machine base 10 and the other end connected to the clamping member 6311. One end of the clamping member 6311 is connected to the first driving member 531, and the other end is used to movably clamp the ball bearing so as to place the ball bearing into the first receiving groove 211.

[0060] Furthermore, to achieve precise detection and control of the ball bearing position, this embodiment includes a second detection component (not shown in the figure). The second detection component includes a second sensor and a second controller. The second sensor is located at the end of the second output channel 62 and is used to detect the position of the ball bearing. The second controller is electrically connected to the second sensor and the second drive component 541 and is used to control the action of the second drive component 541 to improve the reliability and efficiency of material feeding. Simultaneously, through the coordinated work of the second sensor and the second controller, automated control is achieved, reducing the need for manual intervention and improving the stability and continuity of the production process.

[0061] See Figure 9 In order to ensure the orderly operation of subsequent operations, a baffle assembly 70 is also provided in this embodiment to prevent the ball bearing from being output to the channel too early above the second output channel 62.

[0062] The material blocking assembly 70 includes a first support frame 71, a fourth driving member 72, and an abutment member 73. The first support frame 71 is mounted on the machine base 10, and its structure is as follows: Figure 9 As shown in the diagram. The fourth driving component 72 is a cylinder, which is mounted on the first support frame 71. Its telescopic end is connected to the abutment component 73, which is used to drive the abutment component 73 to rise and fall above the second output channel 62, and to move and abut against the subsequent ball bearing.

[0063] In summary, the fully automatic oil-impregnated bearing and ball bearing combination press-fitting machine disclosed in this application, by setting up an oil-impregnated bearing feeding mechanism 50 and a ball bearing feeding mechanism 60, realizes automatic feeding of oil-impregnated bearings and ball bearings, significantly improving production efficiency, reducing manual intervention, and lowering labor intensity and production costs. The design of the ejector pin assembly 30 ensures precise axial movement of the oil-impregnated bearing during the press-fitting process, avoiding the offset or misalignment problems common in traditional equipment, and improving the accuracy and reliability of the press-fitting. The precision design of the pressing assembly 40 ensures the stability and consistency of the ball bearing during press-fitting, effectively improving the overall quality and performance of the product.
