Description

Technical Field

[0001] This invention relates to the field of gear press-fitting technology, and in particular to an automatic gear detection and press-fitting device. Background Technology

[0002] In the field of mechanical transmission, press-fitting of gears and shafts is a widely used and crucial assembly process. This process applies enormous axial pressure to create an interference fit between the inner bore of the gear and the shaft, relying on the significant static friction generated by the elastic deformation of the material to transmit torque and axial force. To ensure press-fitting quality and avoid abnormal press-fitting force, part damage, or even breakage due to dimensional deviations, automated inspection of key dimensions such as the inner diameter of the gear and the shaft before press-fitting has become an indispensable step. By adhering to the principle of "test before assembly," defective products can be eliminated at the source, and press-fitting parameters can be intelligently adjusted based on the measured dimensions, thereby ensuring the consistency and reliability of the final product.

[0003] However, in the current press-fitting production of small gear parts and shafts, especially in scenarios with multiple varieties and small batches, manual operation is still heavily relied upon. Operators need to manually pick up tiny gear parts and perform preliminary placement and alignment on the shafts. This is labor-intensive and requires extremely high levels of eyesight and operational proficiency. This manual pre-fitting method is inefficient and has become a bottleneck for improving the cycle time of automated production lines. More seriously, because the accuracy of manual alignment is difficult to guarantee, in the subsequent automated press-fitting process, the mating surfaces of the gear parts and shafts are easily scratched, scratched, or damaged due to initial alignment deviations. In some cases, stress concentration can even cause the gear parts to crack or the journals to collapse, directly leading to the scrapping of parts and increasing production costs and quality risks. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide an automatic gear detection and pressing device that can solve the technical problems of product scratches, high scrap rate, low production efficiency and high labor intensity caused by poor alignment accuracy of manually placed gear workpieces in the prior art.

[0005] The technical solutions provided by the embodiments of the present invention are as follows: An embodiment of the present invention provides an automatic gear detection and pressing device, comprising: a housing, a support rod, a tray, a drive motor, a rotating disk, a placement mechanism, a pressing mechanism, a detection mechanism, and a feeding mechanism; The system comprises four support rods, which are fixed to the upper end of the housing. The tray is fixed to the upper end of the four support rods. The drive motor is located on the upper end of the inner wall of the housing. The lower end of the rotating disk is connected to the output end of the drive motor. The system comprises four placement mechanisms, which are circumferentially arranged above the rotating disk. The pressing mechanism is located on one side of the upper end of the housing. The detection mechanism is located on one side of the upper end of the housing. The feeding mechanism is located on one side of the upper end of the housing and is situated above one of the placement mechanisms. The placement mechanism includes a placement seat and a centering positioning mechanism disposed above the placement seat; The feeding mechanism includes a connecting rod, a C-shaped plate, a moving cylinder, a lifting mechanism, and a pressing mechanism; The number of connecting rods is two sets. The lower ends of the two connecting rods are connected to the upper sides of the box. The C-shaped plate is set on the upper end of the two connecting rods. The two sides of the C-shaped plate are connected to the moving cylinders. The output ends of the two moving cylinders are connected to the supporting mechanism. The middle of the upper part of the C-shaped plate is connected to the pressing mechanism.

[0006] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following: In this embodiment of the invention, the multi-station rotary table layout integrates the processes of feeding, inspection, pre-pressing and pressing. Each station operates in a cyclical manner based on the rotary table, forming a continuous production process, which significantly improves equipment utilization. Furthermore, the visual inspection equipment set before pressing can measure the size and inspect the appearance of the workpiece, effectively identifying defective products and preventing defective workpieces from entering subsequent processes. This not only ensures product consistency but also improves overall production efficiency.

[0007] In this embodiment of the invention, a central positioning mechanism drives multiple positioning wheels to achieve synchronous centering motion. This mechanism can automatically complete the precise centering and reliable clamping of the shaft. Its flexible clamping method avoids damage to the workpiece surface, provides a stable process benchmark for subsequent processes, and ensures the precise centering of the gear workpiece and shaft during the assembly process, creating the necessary conditions for forming a high-quality interference fit.

[0008] In this embodiment of the invention, the gear feeding mechanism enables precise positioning and stable release of gear workpieces, while also completing preliminary pre-fitting. This effectively solves the problems of inaccurate positioning and unstable conveying that easily occur in the automated assembly of small-sized gear workpieces, ensuring the continuity and reliability of the assembly process and providing key technical support for the smooth implementation of automated production.

[0025] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention.

[0026] Reference manual attached Figures 1 to 11 An embodiment of the present invention provides an automatic gear detection and pressing device, comprising: a housing 1, a support rod 2, a tray 3, a drive motor 4, a rotating disk 5, a placement mechanism, a pressing mechanism, a detection mechanism, and a feeding mechanism.

[0027] There are four support rods 2, which are fixed to the upper end of the box body 1. The tray 3 is fixed to the upper end of the four support rods 2. The drive motor 4 is located on the upper end of the inner wall of the box body 1. The lower end of the rotating disk 5 is connected to the output end of the drive motor 4. There are four sets of placement mechanisms, which are all circumferentially arranged above the rotating disk 5. The pressing mechanism is located on one side of the upper end of the box body 1. The detection mechanism is located on one side of the upper end of the box body 1. The feeding mechanism is located on one side of the upper end of the box body 1, and is located above one of the placement mechanisms.

[0028] Four support rods 2 provide stable four-point support for the tray 3 and its upper components. The tray 3 is used to support the rotating disk 5. The drive motor 4 provides precise rotational power for the intermittent indexing movement of the rotating disk 5. The rotating disk 5 drives four sets of placement mechanisms to perform precise positioning and conversion between four workstations. During the workstation conversion process, the placement mechanism is used to complete the positioning, clamping and fixing of the shaft. The pressing mechanism applies precise and controllable axial pressure to the pre-fitted gear workpiece to form an interference fit. The detection mechanism performs online visual inspection of the inner diameter, shaft diameter and fit status of the gear workpiece. The feeding mechanism completes the gripping, precise positioning, reliable release and preliminary pre-fitting of the gear workpiece.

[0029] The placement mechanism includes a placement seat 6 and a centering positioning mechanism disposed above the placement seat 6.

[0030] The mounting base 6 serves as the mounting reference and positioning foundation for the shaft. The centering positioning mechanism enables automatic centering, precise alignment, and reliable clamping of the shaft. The feeding mechanism includes a connecting rod 23, a C-shaped plate 24, a moving cylinder 25, a lifting mechanism, and a pressing mechanism.

[0031] There are two sets of connecting rods 23. The lower ends of the two connecting rods 23 are connected to the upper sides of the housing 1. C-shaped plates 24 are set on the upper ends of the two connecting rods 23. Movable cylinders 25 are connected to both sides of the C-shaped plates 24. The output ends of the two movable cylinders 25 are connected to the support mechanism. A pressing mechanism is connected to the middle of the upper end of the C-shaped plates 24.

[0032] The connecting rod 23 is used to construct the mounting frame of the feeding mechanism and provide stable support. The C-shaped plate 24 is used to integrate and install the moving drive, clamping execution and pressing linkage components. The moving cylinder 25 can adjust the position of the moving block 26. The lifting mechanism is used to perform reliable lifting, smooth conveying and precise release of the gear workpiece. The pressing mechanism is used to realize the automatic release control of the gear workpiece and complete the initial pre-pressing positioning.

[0033] like Figures 1-3As shown: In one possible implementation, the upper center of the tray 3 has an opening, the output end of the drive motor 4 passes through the box 1 and the tray 3 and extends to the upper end of the tray 3, the middle of the tray 3 has a receiving space, the rotating disk 5 is disposed in the receiving space, and the pressing mechanism is located directly above one of the placement mechanisms.

[0034] Specifically, the space above the tray 3 allows for the compact installation and stable rotation support of the rotating disk 5. The pressing mechanism is installed directly above the placement mechanism, ensuring that the pressing force of the pressing mechanism is precisely aligned with the workpiece axis.

[0035] like Figure 3 As shown: In one possible implementation, the inspection mechanism includes an inspection frame 21 and a visual inspection device 22.

[0036] The lower end of the inspection frame 21 is connected to one side of the upper end of the box 1. The inspection frame 21 is located on one side of one of the placement mechanisms. There are two visual inspection devices 22. The two visual inspection devices 22 are respectively set on one side of the inspection frame 21 and the lower side of the inspection frame 21. The inspection frame 21 is set in an inverted L-shaped structure.

[0037] Specifically, the inspection frame 21 provides a stable and reliable installation platform for the vision inspection equipment 22. The two vision inspection equipment 22 acquire images of the size and position of the gear workpiece and shaft from the side and above, respectively. The inverted L-shaped structure of the inspection frame 21 is used to realize the multi-angle arrangement of the vision inspection equipment 22.

[0038] like Figures 4-5 As shown: In one possible implementation, the lower end of the placement seat 6 is connected to the upper end of the rotating disk 5, and a stabilizing groove 7 is provided in the middle of the upper end of the placement seat 6. The centering positioning mechanism includes a limiting cylinder 8, an adjusting rod 9, a positioning wheel 10, and a driving mechanism.

[0039] The limiting cylinder 8 is set above the placement seat 6. The limiting cylinder 8 is hollow. There are three adjusting rods 9. All three adjusting rods 9 are circumferentially set inside the limiting cylinder 8 and are rotatably connected to the lower end of the inner wall of the limiting cylinder 8. There are three positioning wheels 10. The three positioning wheels 10 are respectively installed at one end of the three adjusting rods 9. The outer wall of the three adjusting rods 9 is connected to a drive mechanism.

[0040] Specifically, the limiting cylinder 8 serves as the mounting housing for the positioning mechanism and provides guidance for the moving parts. The adjusting rod 9 converts the linear motion of the drive mechanism into the radial centering motion of the positioning wheel 10. The positioning wheel 10 is used to achieve three-point centering of the shaft and non-damaging flexible clamping. The drive mechanism is used to coordinate multiple positioning wheels 10 to achieve synchronous radial centering motion.

[0041] like Figure 5As shown: In one possible implementation, the driving mechanism includes three sliding frames 11. The three sliding frames 11 are respectively sleeved on the outer walls of three adjusting rods 9 and slidably connected to the corresponding outer walls of the adjusting rods 9. Rotating rods 14 are rotatably connected to the upper and lower ends of the three sliding frames 11. Rotating rings 12 are slidably connected to the upper and lower ends of the inner wall of the limiting cylinder 8. Rotating blocks 13 are connected to the inner walls of the two rotating rings 12 at the corresponding positions of the sliding frames 11. Multiple rotating blocks 13 are respectively sleeved on the outer walls of the corresponding rotating rods 14. Openings are opened at the middle of the multiple rotating blocks 13 at the corresponding positions of the rotating rods 14. Multiple rotating rods 14 are respectively inserted into the corresponding openings. An electric telescopic rod 15 is connected to one side of the inner wall of the limiting cylinder 8. A toggle block 16 is rotatably connected to the output end of the electric telescopic rod 15. One side of the toggle block 16 is rotatably connected to the two rotating rings 12 via a rotating shaft.

[0042] Specifically, the sliding frame 11 converts the rotational motion of the rotating ring 12 into the precise swing of the adjusting rod 9. The rotating rod 14 connects the sliding frame 11 and the rotating block 13 to form a complete transmission chain. The rotating ring 12 converts the single axial drive into synchronous motion in the circumferential direction. The rotating block 13 transmits the circumferential motion of the rotating ring 12 to the rotating rod 14. The electric telescopic rod 15 provides precise linear drive for the entire centering mechanism. The actuating block 16 converts the linear motion of the electric telescopic rod 15 into the tangential driving force of the rotating ring 12. The actuating block 16 is rotatably connected to the two rotating rings 12 to ensure that the driving force is evenly distributed.

[0043] like Figures 2-3 As shown: In one possible implementation, the pressing mechanism includes a support frame 17, a hydraulic cylinder 18, a movable plate 19, and a pressing block 20.

[0044] The support frame 17 is located on the upper end of the housing 1. The support frame 17 is arranged in an inverted U-shape. A hydraulic cylinder 18 is connected to the middle of the upper end of the support frame 17. The output end of the hydraulic cylinder 18 extends through to the lower end of the support frame 17. A movable plate 19 is connected to the output end of the hydraulic cylinder 18. A pressing block 20 is connected to the middle of the lower end of the movable plate 19. The pressing block 20 is located above one of the placement mechanisms. Guide rods are connected to both sides of the upper end of the support frame 17. The movable plate 19 slides along the outer walls of the two guide rods on both sides.

[0045] Specifically, the support frame 17 is a rigid support structure for the pressing mechanism, the pressing mechanism provides installation space, the hydraulic cylinder 18 can provide a smooth and powerful pressing force, the moving plate 19 is used to transmit the thrust of the hydraulic cylinder 18 and ensure motion stability, the pressing block 20 applies pressure evenly to the end face of the gear workpiece, the pressing block 20 is located directly above the gear workpiece, which can ensure that the pressing force coincides with the axis of the workpiece, and the guide rod can prevent the moving plate 19 from deflecting during the pressing process.

[0046] like Figures 6-10As shown: In one possible implementation, the placement mechanism includes a moving block 26, a guide rail 27, a guide slider 28, a rotating rod 29, a clamping block 30, a buffer spring 31, and a placement groove 32.

[0047] There are two sets of movable blocks 26. The output ends of two movable cylinders 25 extend through to both sides of the C-shaped plate 24. One side of each of the two movable blocks 26 is connected to one end of the movable cylinder 25. The cross-sectional shape of the movable blocks 26 is L-shaped. The middle part of one side of each of the two movable blocks 26 is connected to the output ends of the two movable cylinders 25. A guide rail 27 is connected to the middle of one side of the C-shaped plate 24. A guide slider 28 is connected to the middle of one side of each of the two movable blocks 26. The two guide sliders 28 slide on the outer wall of the guide rail 27. A rotating rod 29 is connected to the middle of one side of each of the two movable blocks 26. A clamping block 30 is sleeved on the outer wall of the two rotating rods 29. The clamping block 30 is L-shaped. The two clamping blocks 30 are rotatably connected to the corresponding side of the movable block 26.

[0048] Specifically, the movable block 26 carries the clamping assembly for lateral movement. The L-shaped movable block 26 is used to install the clamping mechanism. The guide rail 27 and the guide slider 28 provide a precise linear trajectory for the movement of the movable block 26. The rotating rod 29 serves as the rotation fulcrum of the clamping block 30. The lower end of the clamping block 30 is inclined and can be used to set the placement groove 32. At the same time, the inclined setting is linked with the pressing mechanism. The rotational connection between the clamping block 30 and the movable block 26 is used to realize the clamping and releasing action of the clamping block 30.

[0049] like Figures 8-11 As shown: In one possible implementation, buffer springs 31 are connected to the upper part of one side of each of the two clamping blocks 30. The buffer spring 31 on one side of one clamping block 30 is connected to the side of the corresponding moving block 26, and the buffer spring 31 on the other side of the clamping block 30 is connected to the side of the corresponding moving block 26. Placement slots 32 are provided on the lower part of one side of the two clamping blocks 30. One end of the placement slot 32 is arc-shaped. The two placement slots 32 are used to place gear workpieces.

[0050] Specifically, the buffer spring 31 is a reset spring that allows the clamping block 30 to close automatically when no external force is applied. The buffer spring 31 is used to provide closing force for the clamping block 30. The placement groove 32 is used to support and initially position the gear workpiece. The clamping block 30 is a replaceable design. For gear workpieces of different diameters, clamping blocks 30 with different specifications of arc-shaped placement grooves 32 can be replaced.

[0051] like Figure 8 As shown: In one possible implementation, the pressing mechanism includes a top plate 33, a telescopic cylinder 34, a pressing block 35, a roller 36, and a pre-pressing rod 37.

[0052] The top plate 33 is in the shape of an inverted L-shape. A telescopic cylinder 34 is connected to the middle of the upper end of the top plate 33. The output end of the telescopic cylinder 34 extends through to the bottom of the top plate 33. A pressure block 35 is connected to the output end of the telescopic cylinder 34.

[0053] Specifically, the top plate 33 is used to install the telescopic cylinder 34, which provides linear motion in the vertical direction. The lower pressure block 35 can install the roller 36 and the preload rod 37, which is used to apply a certain preload after the gear workpiece is released, so that it is initially fitted onto the shaft.

[0054] like Figures 8-9 As shown: In one possible implementation, rollers 36 are embedded on both sides of the lower pressure block 35. Rolling grooves are connected to the two rollers 36 on both sides of the lower pressure block 35. The two rollers 36 are located inside the two rolling grooves respectively. One side of the two rollers 36 contacts the upper part of one side of the two clamping blocks 30 respectively. A preload rod 37 is connected to the middle of the lower end of the lower pressure block 35.

[0055] Specifically, the roller 36 converts the vertical downward pressure into a horizontal component force that drives the clamping block 30 to open. The rolling groove is used to limit the axial movement of the roller 36. The contact between the roller 36 and the clamping block 30 enables the transmission of the movement of the pressing block 35 to the clamping block 30. The preload rod 37 directly presses down on the gear workpiece when the pressing block 35 moves downward.

[0056] It should be noted that the power supply and control methods of the drive motor 4, electric telescopic rod 15, hydraulic cylinder 18, moving cylinder 25, telescopic cylinder 34 and vision inspection equipment 22 involved in this invention are all common knowledge and conventional settings in the field and belong to the scope of prior art. Therefore, they will not be described in detail in this article.

[0057] Working Principle: When using the device, the shaft is first clamped and positioned. The operator or robot places the shaft vertically in the stabilizing groove 7 of the placement seat 6. At this time, the shaft is in a preliminary positioning state. Then, the centering positioning mechanism begins the precise positioning operation: the electric telescopic rod 15 pushes the actuating block 16 to make linear motion. The actuating block 16 drives the two rotating rings 12 to rotate synchronously in the limiting cylinder 8. The motion of the rotating rings 12 is transmitted to multiple rotating rods 14 through the rotating block 13. These rotating rods 14 drive the three sliding frames 11 to slide along the axial direction of the adjusting rod 9. Since the adjusting rod 9 and the limiting cylinder 8 are rotatably connected, the linear motion of the sliding frame 11 can be converted into the rotational motion of the adjusting rod 9, thereby driving the three positioning wheels 10 to retract radially towards the center synchronously, finally precisely centering and firmly clamping the shaft in the center position of the limiting cylinder 8.

[0058] After the shaft is positioned, the drive motor 4 starts and rotates the placement mechanism with the fixed shaft to the bottom of the feeding mechanism via the rotating disk 5. At this time, the operator or robot accurately places the gear workpiece into the two placement slots 32 of the support mechanism. Because the arc-shaped structure of the placement slot 32 is precisely matched with the shape of the gear workpiece, when the gear workpiece is placed, the outer edge of the gear workpiece fits against the arc-shaped inner wall of the placement slot 32, achieving the initial positioning of the gear workpiece and ensuring that the shaft hole of the gear workpiece remains coaxial with the already centered shaft below.

[0059] The gear workpiece is then fitted together, and the pressing mechanism begins to operate. The telescopic cylinder 34 pushes the pressing block 35 downward, and the rollers 36 on both sides of the pressing block 35 roll along the inclined surface above the two clamping blocks 30. This rolling process generates a radial force, forcing the two clamping blocks 30 to rotate on the outer wall of the rotating rod 29, causing the lower ends of the two clamping blocks 30 to move away from each other. Due to the angle adjustment of the clamping blocks 30, the buffer spring 31 is stretched and releases its elasticity, causing the two placement slots 32 to separate. The gear workpiece, having lost its support, falls naturally under gravity and is fitted onto the shaft below. At the same time, the preload rod 37 in the middle of the pressing block 35 presses down synchronously, applying a precise preload to the falling gear workpiece to ensure that the gear workpiece and the shaft achieve initial stable fitting.

[0060] After the connection is completed, the telescopic cylinder 34 retracts, causing the lower pressure block 35 and the pre-pressure rod 37 to rise synchronously. The roller 36 rises, releasing the pressure on the two clamping blocks 30. The buffer spring 31 retracts, pulling the clamping blocks 30 back to their original positions.

[0061] After the gear workpiece is assembled, the rotating disk 5 continues to rotate, transporting the workpiece to the inspection station. The two vision inspection devices 22 installed on the inspection frame 21 are started at the same time, and image acquisition and inspection of the assembled gear workpiece and shaft are performed from different angles. The inner diameter of the gear workpiece, the diameter of the shaft, and the fit between the two are accurately measured to ensure that all dimensional parameters meet the design requirements.

[0062] Finally, the qualified workpiece is rotated to the pressing station by the rotating disk 5. The hydraulic cylinder 18 of the pressing mechanism is activated, pushing the moving plate 19 to move smoothly down along the guide rod. The pressing block 20 at the lower end of the moving plate 19 presses the gear workpiece from the pre-installed position to the final position required by the design at a constant speed and pressure.

[0063] The entire process of press-fitting gear parts and shafts has been automated, effectively ensuring the consistency and stability of product quality.
