Description

Technical Field

[0001] This utility model relates to the field of bushing pressing technology, and in particular to a bushing pressing machine. Background Technology

[0002] In modern industrial manufacturing, bushing press-in is a crucial step in many mechanical assemblies. Bushings, as important mechanical components, primarily serve to reduce wear, provide support, and offer positioning. However, most current bushing press-in machines rely on manual operation to place bushings and related components (such as bearings). This traditional working method not only requires highly skilled and experienced workers but also suffers from significant limitations in efficiency and accuracy.

[0003] Specifically, existing bushing press-in machines typically require operators to manually and precisely place the bushings and bearings into the corresponding fixtures. This process is cumbersome and time-consuming. After the press-in process is completed, the removal of the finished product and the placement of subsequent workpieces also require manual intervention, which further limits the overall efficiency of the production line. Because these devices lack automated material handling systems, they cannot achieve automated transfer of bushings from the storage location to the fixture, nor can they achieve automated feeding processes after the bearings are pressed in, resulting in low efficiency throughout the production process and increased labor costs.

[0041] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0042] like Figure 1 and Figure 2As shown, this utility model provides a bushing pressing machine, including a frame 1, a positioning fixture 2 for placing bearings, a feeding mechanism 3, a pressing mechanism 4, a distributing mechanism 5, and a transport mechanism 6. The frame 1 serves as the basic structure of the entire equipment, used to install and support other components. The positioning fixture 2, feeding mechanism 3, pressing mechanism 4, distributing mechanism 5, and transport mechanism 6 are all installed on the frame 1. The feeding mechanism 3 is used to transport the bearings to a designated position. The distributing mechanism 5 is located at the input end of the transport mechanism 6 and is used to separate the bushings so that the bushings can be transported from the distributing mechanism 5 to the transport mechanism 6. This ensures that the bushings are transported sequentially along the transport direction of the distributing mechanism 5 towards the transport mechanism 6, avoiding material accumulation or leakage. The output end of the transport mechanism 6 is provided with a positioning fixture 2 so that the bushings can be transported to the positioning fixture 2 by the transport mechanism 6. The positioning fixture 2 is used to place the bearings. The pressing mechanism 4 is installed above the positioning fixture 2 to ensure that the bushings are pressed into the bearings during the pressing process.

[0043] Based on the above structure, the bearing in this embodiment is placed on the feeding mechanism 3 and transported to the positioning fixture 2 by the feeding mechanism 3. The bushing is divided by the material distribution mechanism 5 and then transported to the positioning fixture 2 by the transport mechanism 6. Then the pressing mechanism 4 presses the bushing into the bearing. Finally, the feeding mechanism 3 transports the finished product to the designated position. Through the coordinated work of the above parts, the entire process from automatic feeding, positioning, pressing of bushings and bearings to finished product output is automated, which solves the problems of low efficiency and high cost caused by traditional manual operation. It also improves product quality by improving assembly accuracy.

[0044] Please see Figure 4 The positioning fixture 2 includes a turntable 21, a mounting component 22 for placing bearings, a first drive component 23, a second drive component 24, and an air blowing component 25. The turntable 21 has multiple positioning holes 211 and mounting holes 212. The multiple positioning holes 211 are spaced apart around the axis of the turntable 21. The mounting component 22 is installed in the corresponding positioning hole 211. The first drive component 23 is connected to the turntable 21 to drive the turntable 21 to rotate. By rotating the turntable 21, different mounting components 22 (and the bearings on them) can be moved to the designated working position in sequence. The second drive component 24 is connected to the mounting component 22 to push the mounting component 22 out of the positioning hole 211. Through the above-mentioned push-out operation, it is convenient to place the bushing on the bearing and perform the pressing operation. At the same time, through the push-out action, the finished product can be more easily removed from the positioning fixture 2, improving work efficiency. The air blowing component 25 is installed in the mounting hole 212 and faces the mounting component 22. It removes small particulate impurities generated during the pressing process by spraying gas.

[0045] In this embodiment, the coordinated use of the first driving component 23 and the second driving component 24 enables the positioning, transfer, and unloading of the workpiece, while the air blowing component 25 helps maintain the cleanliness of the working environment and improves the smoothness of workpiece processing. In this embodiment, the turntable 21 is mounted on the frame 1 via a support frame 26. The first driving component 23 and the second driving component 24 in this embodiment can be servo motors, cylinders, or other driving components, and are not specifically limited here.

[0046] like Figure 5 As shown, the pressing mechanism 4 includes a first mounting frame 41, a third driving component 42, a pressing head structure 43, a dust collection funnel 44, and a rotating fixing plate 45. The first mounting frame 41 is mounted on the frame 1, providing a stable support platform to ensure that other components can operate stably and accurately. Two third driving components 42 are installed at intervals on the first mounting frame 41, and the output end of the third driving component 42 is connected to the pressing head structure 43 to drive the pressing head structure 43 to move up and down. The pressing head structure 43 is set towards the positioning fixture 2. By controlling the third driving component 42, the up and down movement of the pressing head structure 43 can be adjusted, thereby achieving a precise pressing operation on the bushing. Two rotating fixing plates 45 are installed opposite each other on both sides of the first mounting frame 41, and the dust collection funnel 44 is rotatably mounted on the corresponding rotating fixing plate 45 to block and collect dust and debris generated during the pressing process. At the same time, by setting the rotatable dust collection funnel 44, the dust collection position can be adjusted according to actual needs to achieve a better cleaning effect.

[0047] In this embodiment, the lifting and lowering movement of the pressure head structure 43 is controlled by the third drive component 42, which ensures the accuracy of the pressing process, while the dust collection funnel 44 helps to maintain the cleanliness of the work area and reduce quality problems caused by dust and debris.

[0048] It should be noted that the pressure head structure 43 in this embodiment can be a conventional bushing pressure head structure 43, and its structure is not particularly limited here. There can be multiple pressure head structures 43, and different pressure head structures 43 can be used by rotating the turntable 21. The third driving component 42 in this embodiment can be a servo motor, cylinder, or other driving component, and is not particularly limited here.

[0049] like Figure 6As shown, the material distribution mechanism 5 includes a vibratory plate 51, a linear vibrator 52, a linear vibrating rail 53, a material distribution assembly 54, and a transport assembly 55. The vibratory plate 51 moves the bushings within the plate by vibration and arranges them along a specific path for output. The vibratory plate 51 is connected to the material distribution assembly 54 via the linear vibrating rail 53. The linear vibrator 52 is installed on the linear vibrating rail 53. The linear vibrator 52 provides power by generating directional vibration to move the bushings along the direction of the linear vibrating rail 53, so as to transport the bushings to the material distribution assembly 54. The material distribution assembly 54 receives the bushings from the linear vibrating rail 53 and further separates them. Two transport assemblies 55 are installed opposite each other at both ends of the material distribution assembly 54 to transport the corresponding bushings that have been separated by the material distribution assembly 54 to the transport mechanism 6.

[0050] The material distribution mechanism 5 in this embodiment realizes the automatic sorting, feeding and transportation of bushings, thereby improving production efficiency and automation. The bushings are initially sorted by the vibrating plate 51, and then the transmission path of the bushings is controlled by the linear vibrating rail 53 and the linear vibrator 52. Finally, the arrangement and separation of the bushings are completed by the material distribution component 54. The whole process is highly automated and reduces the need for manual intervention.

[0051] like Figure 7 As shown, the material distribution assembly 54 includes a fourth drive component 541, a first slide rail 542, a material distribution block 543, a first slider 544, a material distribution section 545, and a second mounting frame 546. The second mounting frame 546 provides a stable platform to ensure the stable operation of other components. It is mounted on the frame 1. The first slide rail 542, the fourth drive component 541, and the material distribution section 545 are mounted on the second mounting frame 546. The material distribution section 545 has a slot 5451 communicating with the linear vibrating rail 53 and a material trough 5452. The slot 5451 is used to receive bushings from the linear vibrating rail 53 and guide them into the material trough 5452. The two ends of the material trough 5452 are respectively connected to the corresponding conveyor belts. The conveying component 55 is connected, and the slot 5451 is located between the two ends of the material trough 5452 and is connected to the material trough 5452. The material separating block 543 is slidably connected to the first slide rail 542 through the first slider 544, and the material separating block 543 is slidably installed in the material trough 5452, so that the material separating block 543 moves back and forth smoothly in the material trough 5452, ensuring that the bushing can be transported to the designated position. The fourth driving member 541 is connected to the first slider 544 to drive the material separating block 543 to move back and forth in the material trough 5452. By controlling the working state of the fourth driving member 541, the moving speed and position of the material separating block 543 can be controlled, thereby ensuring the sorting and transmission of the bushing. In this embodiment, the fourth driving member 541 can be a servo motor, cylinder, or other driving member, and is not particularly limited here.

[0052] The material sorting component 54 in this embodiment realizes the automatic sorting and transportation of bushings, improving production efficiency and automation level. After being initially sorted by the vibratory plate 51, the bushings enter the material sorting section 545 via the straight vibrating rail 53. Under the action of the material sorting block 543, the bushings are pushed one by one into the corresponding transportation component 55, which not only reduces the need for manual intervention, but also improves the accuracy and stability of material transmission, and helps to maintain the smooth operation of the production line.

[0053] It should be noted that the material separating block 543 in this embodiment has notches 5431 at both ends for placing the bushing and driving the bushing to move. Depending on actual needs, the notches 5431 can be set to be the same size or different sizes to facilitate separation.

[0054] like Figure 8 As shown, the transport component 55 includes a third mounting bracket 551, a fifth drive component 552, a second slide rail 553, a second slider 554, a third slide rail 555, a third slider, a connecting block 556, a pusher block 557, a fixing block 558, a spring component 559, and a mounting block 5510. The third mounting bracket 551 provides a stable platform to ensure the stable operation of other components. It is mounted on the frame 1. The second slide rail 553 and the third slide rail 555 are spaced apart on the third mounting bracket 551. The second slider 554 is slidably mounted on the second slide rail 553, and the third slider is slidably mounted on the third slide rail 555. The connecting block 556 is mounted on the second slider 554, and the mounting block 5510 is mounted on the third slide rail 555. The third slider is mounted on the connecting block 556, which is connected to the mounting block 5510. The mounting block 5510 has a groove. The pusher block 557 is mounted on the mounting block 5510 and, together with the groove, defines the mounting slot for the bushing. The fixing block 558 is mounted on the mounting block 5510, and the two ends of the spring member 559 abut against the fixing block 558 and the pusher block 557 respectively, providing a certain elastic support to better fix and adapt to the size of the bushing. The fifth drive member 552 is connected to the connecting block 556, so that the fifth drive member 552 can drive the second slider 554 and the third slider simultaneously through the connecting block 556, thereby driving the mounting block 5510 and its components to move together.

[0055] In this embodiment, the transport component 55 realizes the transfer of the bushing from the dispensing component 54 to the transport mechanism 6. By using multiple sets of slide rails and sliders, and the elastic support provided by the spring component 559, the system can ensure the stability and accuracy of the bushing during transport. In this embodiment, the fifth drive component 552 can be a servo motor, cylinder, or other drive component, and is not particularly limited here.

[0056] like Figure 9 and Figure 10As shown, the feeding mechanism 3 includes a fourth mounting frame 31, a sixth driving component 32, a conveyor belt 33, a transmission structure 34, a positioning switch 35, a fifth mounting frame 36, a first gripper assembly 37, a fourth slide rail 38, a fourth slider 39, and a seventh driving component 310. The fourth mounting frame 31 is mounted on the frame 1 to provide stable support for other components. The transmission structure 34, the conveyor belt 33, and the sixth driving component 32 are mounted on the fourth mounting frame 31. The sixth driving component 32 is connected to the conveyor belt 33 through the transmission structure 34 to provide power to the conveyor belt 33, enabling it to run smoothly and realize the automatic transfer of materials (such as bearings). The conveyor belt 33 has multiple placement positions. A positioning switch 35 is installed on the fourth mounting frame 31 to detect whether the placement position has reached the gripping position (i.e., the operating position of the first gripper assembly 37), ensuring that the material can be gripped in each operation. A fifth mounting frame 36 is installed on the fourth mounting frame 31, a fourth slide rail 38 is installed on the fifth mounting frame 36, a fourth slider 39 is slidably installed on the fourth slide rail 38, a seventh drive unit 310 is connected to the fourth slider 39, and the first gripper assembly 37 is installed on the fourth slider 39, so that the first gripper assembly 37 moves horizontally along the direction of the fourth slide rail 38 to accurately grip or release the material.

[0057] This embodiment achieves automated material handling through an integrated drive system (including a sixth drive component 32 and a seventh drive component 310), a conveying system (conveyor belt 33), a positioning system (positioning switch 35), and a gripping system (first gripper assembly 37), reducing the need for manual intervention and accelerating the production process. The sixth drive component 32 and the seventh drive component 310 in this embodiment can be servo motors, cylinders, or other drive components, and are not specifically limited here.

[0058] Furthermore, it should be noted that after the bearing is processed, it is still transported by the first gripper assembly 37 to the end of the conveyor belt 33 away from the feed end for product output, reducing the complexity of the system structure. In this embodiment, the first gripper assembly 37 includes a servo motor or cylinder and other driving components, as well as grippers, which are driven by the servo motor or cylinder to perform gripping.

[0059] like Figure 2 , Figure 11 and Figure 12As shown, it also includes a bearing flipping assembly 7, which includes a sixth mounting bracket 71, an eighth drive member 72, a ninth drive member 73, a second gripper assembly 74, a fifth slide rail 75, and a fifth slider 76. The sixth mounting bracket 71 is mounted on the frame 1 to provide stable support for other components. The fifth slide rail 75 and the eighth drive member 72 are mounted on the sixth mounting bracket 71. The fifth slider 76 is slidably mounted on the fifth slide rail 75. The eighth drive member 72 is connected to the fifth slider 76 to drive the fifth slider 76 to move up and down. By controlling the working state of the eighth drive member 72, the height position of the second gripper assembly 74 can be adjusted to facilitate gripping or releasing the bearing. The ninth drive member 73 is mounted on the fifth slider 76 and connected to the second gripper assembly 74 to drive the second gripper assembly 74 to flip, so that the gripped bearing can change its orientation or posture to meet the needs of subsequent processes.

[0060] This embodiment, through the coordinated operation of the eighth driving component 72 and the ninth driving component 73, allows for flexible adjustment of the height and flipping angle of the second gripper assembly 74, enabling the bearing to be adjusted accordingly. This reduces the need for manual intervention and improves the overall efficiency of the production line. It should be noted that due to differences in bearing structure, some bearings require flipping to facilitate subsequent pressing operations. The second gripper assembly 74 in this embodiment includes a servo motor or cylinder as a driving component and grippers, which are driven by the servo motor or cylinder to perform the gripping action. The eighth driving component 72 and the ninth driving component 73 in this embodiment can be a servo motor, cylinder, or other driving component, and are not specifically limited here.

[0061] like Figure 13 As shown, the transport mechanism 6 includes a feeding assembly 61, which includes a seventh mounting frame 611, a sixth slide rail 612, a sixth slider 613, a tenth drive member 614, an eleventh drive member 615, and a third gripper assembly 616. The seventh mounting frame 611 is mounted on the frame 1 to provide stable support for other components. The sixth slide rail 612 and the tenth drive member 614 are mounted on the seventh mounting frame 611. The sixth slider 613 is slidably mounted on the sixth slide rail 612. The tenth drive member 614 is connected to the sixth slider 613 to drive the sixth slider 613 to reciprocate between the dispensing mechanism 5 and the positioning fixture 2. The eleventh drive member 615 is mounted on the sixth slider 613 to provide power so that the sixth slider 613 can move linearly on the sixth slide rail 612 and is connected to the third gripper assembly 616 to drive the third gripper assembly 616 to move up and down, so that the clamped material can move up and down to adapt to different operational needs.

[0062] Based on the above structure, this embodiment achieves horizontal positioning of materials through the combined use of the tenth driving component 614, the sixth slide rail 612, and the slider system. The eleventh driving component 615 is responsible for vertical positioning, ensuring the accuracy of each operation. The automated feeding process reduces the need for manual intervention and improves the overall efficiency of the production line. The third gripper assembly 616 in this embodiment includes a servo motor or cylinder, or other driving component, and a gripper. The gripper is driven by the servo motor or cylinder to perform gripping. The tenth driving component 614 and the eleventh driving component 615 in this embodiment can be a servo motor, cylinder, or other driving component, and are not specifically limited here.

[0063] like Figure 14 As shown, the transport mechanism 6 also includes a positioning assembly 62, which includes a vision unit (not shown), an eighth mounting bracket 621, a twelfth drive unit 622, a mounting base 623 for placing bushings, a proximity switch 624, and an oil drain box 625. The eighth mounting bracket 621 is mounted on the frame 1 to provide stable support for other components; the twelfth drive unit 622 and the oil drain box 625 are mounted on the eighth mounting bracket 621. The oil drain box 625 is used to collect and treat waste oil or other liquids that may be generated during operation, maintaining the cleanliness of the working environment; the twelfth drive unit 622... The output of component 2 is connected to the placement seat 623 to drive the placement seat 623 to rotate, allowing the direction or posture of the bushing to be adjusted as needed, ensuring that it can be matched with the corresponding bearing for pressing operation. The proximity switch 624 is set towards the transport component 55 to detect the position of the mounting block 5510, ensuring that the system can respond in a timely manner and execute the next operation when the material arrives at the designated position, ensuring the continuity and accuracy of the process. The vision unit is used to acquire image information of the bushing, and can analyze and identify the position, direction, and status of the bushing, thereby achieving precise operation control. For example, it can be used to confirm whether the bushing is correctly placed. The twelfth drive component 622 in this embodiment can be a servo motor, cylinder, or other drive component, and is not particularly limited here.

[0064] This embodiment acquires image information of the bushing through a vision unit. Combined with the precise control of the placement seat 623 by the twelfth drive unit 622, it ensures that the bushing enters the next process in the correct posture and position, reducing the need for manual inspection and adjustment and improving the overall efficiency of the production line. It should be noted that the vision acquisition of bushing information in this embodiment belongs to conventional image processing technology and is not specifically limited thereto.

[0065] It should be noted that, as Figure 3 As shown, the bushing press-fit machine in this embodiment is also equipped with an outer cover 8 for dust prevention or protection of the internal structure, and is also equipped with an operation panel 9, an electrical cabinet 10 and a control unit.

[0066] In summary, this utility model provides a bushing press-in machine that automates the entire process from automatic feeding, positioning, pressing of bushings and bearings to finished product output. It solves the problems of low efficiency and high cost caused by traditional manual operation, and also improves product quality by increasing assembly accuracy.

[0067] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
