DETAILED DESCRIPTION

[0042] The present invention will now be described in further detail with reference to the accompanying drawings.

[0043] See also Figure 1-12As shown in the figure, in this embodiment, a tapping device for processing flange nuts is provided, which includes a workbench 1, on the top of which an external gear 3 is rotatably provided. A driving assembly 5 for driving the external gear 3 to rotate is provided on the workbench 1. A plurality of fixing jigs 13 are spaced apart on the top of the external gear 3. A placement groove 28 is provided through the fixing jig 13. A supporting block 25 is slidably connected in the placement groove 28. A resisting rod 22 is provided on the side of the supporting block 25. The resisting rod 22 penetrates and is movably arranged on the fixing jig 13. A fixing ring 4 is fixedly installed on the workbench 1 relative to the external gear 3. A resisting block 10 that can be in contact with the resisting rod 22 is provided on the fixing ring 4. A fixing plate 12 is provided on the workbench 1. A tapping device 11 is slidably arranged on the fixing plate 12 relative to the fixing jig 13. A lifting device 17 for driving the tapping device 11 to slide is provided on the fixing plate 12.

[0044] Specifically, in this embodiment, the resisting rod 22 penetrates and is movably connected to the fixing jig 13. The resisting rod 22 is slidably arranged on the fixing ring 4. The fixing ring 4 is an annular structure coaxial with the external gear 3. At the same time, the resisting block 10 is an arc-shaped structure, and the resisting block 10 has a horizontal end face and two groups of inclined guiding end faces oppositely arranged on its horizontal end face. This structural setting facilitates the slow movement of the supporting block 25 and avoids the phenomenon that the flange nut falls due to the too-fast movement of the supporting block 25. Secondly, the placement groove 28 has the same outer wall structure as the flange nut (hexagonal nut shape in this embodiment). Further, a plurality of fixing jigs 13 are spaced apart along the circumferential direction of the external gear 3. In the initial state, the supporting block is located in the fixing jig 13, and its bottom is in contact with the inner bottom wall of the fixing jig 13. The resisting rod 22 is in contact with the fixing ring 4. When processing the flange nut, the flange nut is placed in the placement groove 28, and the bottom of the flange nut is in contact with the top of the supporting block 25. The driving assembly 5 drives the external gear 3 to rotate. The fixing jig 13 rotates with the external gear 3 to the tapping station. The lifting device 17 drives the tapping device 11 to move downward to perform thread processing on the flange nut in the placement groove 28. After tapping is completed, the external gear 3 continues to rotate to transfer the processed flange nut to the blanking station. As the external gear 3 rotates, the resisting rod 22 comes into contact with the resisting block 10 and moves along the guiding end face of the resisting block 10, so that the supporting block 25 slowly moves the processed flange nut out of the placement groove 28. When the resisting rod 22 moves to the center position of the horizontal end face of the resisting block 10, the external gear 3 stops rotating. At this time, the blanking of the processed flange nut can be realized, and at the same time, a new flange nut enters the tapping station for processing. Repeat the above steps to realize the processing of the flange nut. The overall structure is simple in operation and high in automation degree. It can facilitate the loading and unloading of the flange nut during the rapid processing of the flange nut, reduce the downtime waiting time, and thus improve the processing efficiency of the flange nut.

[0045] It should be noted that in this embodiment, a handling device 2 for handling flange nuts into the placement groove 28 is fixedly installed in the working state, such as a handling robotic arm, a handling robot, etc. Its structure and working principle are prior arts and will not be described herein. At the same time, the handling device 2, the tapping device 11, and the abutting block 10 respectively correspond to the fixing jigs 13 at different positions to facilitate the normal operation of the device. Secondly, the lifting device 17 is a mechanism that can drive the tapping device 11 to move towards the fixing jig 13, such as a screw lifting mechanism, an electric telescopic rod, etc. Further, the driving assembly 5 includes a fourth gear 52, which is rotatably arranged on the workbench 1 through a third rotating shaft 51. The fourth gear 52 meshes with the external gear 3. A Geneva stop mechanism 53 for driving the intermittent rotation of the third rotating shaft 51 is provided at the bottom of the workbench 1, and the Geneva stop mechanism 53 is driven by a motor 54. The motor 54 is fixedly installed at the bottom of the workbench 1. The external control device controls the continuous rotation of the motor 54. The continuous motion is converted into the intermittent rotation of the third rotating shaft 51 (such as rotating 90° each time) through the Geneva stop mechanism 53. The third rotating shaft 51 drives the fourth gear 52 to rotate, driving the external gear 3 to rotate one station each time, so that the fixing jig 13 is sequentially aligned with the feeding, tapping, and discharging stations. The Geneva stop mechanism 53 realizes the periodic indexing rotation through the engagement of the dial and the Geneva wheel, with high positioning accuracy and is suitable for scenarios that require precise station switching. In this embodiment, the structure and working principle of the Geneva stop mechanism 53 are prior arts and will not be described herein. Secondly, a slider 23 is fixedly connected to the supporting block 25 relatively. A sliding groove 24 through which the slider 23 can slide is provided through the fixing jig 13. The abutting rod 22 is fixedly connected to the slider 23.

[0046] In this embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, it also includes a fixed frame 21, which is arranged on the workbench 1, and a cylinder 19 is provided on the fixed frame 21 relative to the abutment block 10. A collection box 14 is slidably provided on the workbench 1 relative to the cylinder 19. A moving assembly 7 for driving the collection box 14 to move is provided on the workbench 1. A moving plate 18 is fixedly installed at the bottom of the collection box 14. A moving groove 15 for the moving plate 18 to move is penetrated on the workbench 1. The moving assembly 7 includes a first rack 74, which is fixedly installed at the bottom of the moving plate 18 and is rotatably connected to the workbench 1 through a second rotating shaft 77. There is a first gear 73 meshing with the first rack 74, a first rotating shaft 72, which penetrates and is rotatably arranged on the workbench 1, a second rack 75 is fixedly installed on the telescopic end of the cylinder 19, a second gear 76 meshing with the second rack 75 is sleeved on the first rotating shaft 72, and the second rotating shaft 77 and the first rotating shaft 72 are connected by a belt transmission mechanism 71. A discharge assembly 6 is provided on the fixed fixture 13, and the discharge assembly 6 includes a discharge plate 61 fixedly installed on the fixed fixture 13 and a discharge plate 61 relatively arranged along the placement groove 28. 1, the workbench 1 is rotatably connected with a third gear 20 meshing with the first gear 73 and the first rack 74, the diameter of the third gear 20 is smaller than the diameter of the first gear 73, the fixing frame 21 is provided with a cleaning assembly 8, the cleaning assembly 8 includes a blower 81, which is fixedly mounted on the fixing frame 21, a mounting plate 84, which is fixedly mounted on the fixing frame 21, an exhaust tube 83 with an air outlet facing the placement slot 28 is fixedly mounted on the mounting plate 84, and an exhaust port 83 is connected between the exhaust end of the blower 81 and the exhaust tube 83. Pipe 82, a convex tooth 29 which can mesh with the third gear 20 is movably connected on the first rack 74, a movable component 9 for allowing the convex tooth 29 to move is provided in the first rack 74, and the movable component 9 includes a movable plate 91, which is movably arranged in the first rack 74, a movable groove 93 for allowing the movable plate 91 to move is provided in the first rack 74, a spring 94 which resists the movable plate 91 is provided in the movable groove 93, and a movable rod 92 is penetrated and movably arranged on the first rack 74, and its two ends are respectively fixedly connected to the convex tooth 29 and the movable plate 91.

[0047] Specifically, in this embodiment, the collection box 14, the fixing frame 21, and the pushing block are located at the blanking station of the device. One end of the second rack 75 away from the cylinder 19 is fixedly connected to a pushing plate 16, and the bottom of the pushing plate 16 is horizontally arranged with the top of the fixing tooling 13. There is a certain distance between the pushing plate 16 and the placement groove 28. At the same time, the discharge plate 61 is inclined towards the collection box 14, and a gap through which the pushing plate 16 can pass is defined between the two guard plates 62. A plurality of air outlets are provided through the exhaust air cylinder 83 opposite to the placement groove 28 at the top of the fixing tooling 13;In the initial state, the cylinder 19 is in a stationary state, the pushing plate 16 stops at the initial position, the collecting box 14 is located at a position far from the discharging plate 61. When the fixed tooling 13 moves with the movement of the external gear 3 and the abutting rod 22 moves to the horizontal end face of the abutting block 10, at this time, the supporting block 25 pushes the flange nut out along the placing groove 28 and is arranged opposite to the pushing plate 16. At this time, the blower 81 is started, and the air flow is discharged through the exhaust duct 82 into the exhaust cylinder 83 and discharged from the air outlet of the exhaust cylinder 83 to the top of the fixed tooling 13 to blow the waste chips on the fixed tooling 13 away. After the blower 81 is started for a specified time, it stops. Then the cylinder 19 is started and drives the pushing plate 16 and the second rack 75 to move towards the flange nut on the placing groove 28, so that the second gear 76 rotates with the movement of the second rack 75. Since the second gear 76 is sleeved on the first rotating shaft 72, the first rotating shaft 72 will also rotate accordingly. The first rotating shaft 72 drives the second rotating shaft 77 to rotate through the belt transmission mechanism 71. The first gear 73 on the second rotating shaft 77 also rotates accordingly. The first gear 73 drives the third gear 20 to rotate, and the third gear 20 drives the first rack 74 to move, so that the collecting box 14 fixedly connected to the moving plate 18 slides in the moving groove 15 on the workbench 1 to the position corresponding to the discharging plate 61. With the movement of the cylinder 19 driving the pushing plate 16, the pushing plate 16 pushes the flange nut on the top of the supporting block 25 onto the discharging plate 61, so that the flange nut flows into the collecting groove. At the same time, during the continuous movement of the cylinder 19 driving the second rack 75, the third gear 20 will continue to mesh with the convex teeth 29. At this time, the third gear 20 will drive the convex teeth 29 to push the movable plate 91 through the movable rod 92 to squeeze the spring 94. Due to the setting of the spring 94, the convex teeth 29 will reciprocate relative to the first rack 74, so that the first rack 74, the convex teeth 29 and the third gear 20 will always be in a meshing state. When the flange nut falls into the collecting box 14, the cylinder 19 resets, and at this time, it can drive the collecting box 14 to reset. After the cylinder 19 stops, the blower 81 is started to blow the waste chips on the placing groove 28 and the supporting block 25 away. The blower 81 stops running after running for a period of time. Finally, the driving component 5 drives the external gear 3 to rotate to realize the blanking of the next workpiece. The overall structure has a high degree of automation. The cleaning component 8 can clean the waste chips on the fixed tooling 13 before and after the blanking of the flange nut and discharge them along the blanking plate onto the workbench 1, timely discharging the waste generated by tapping, avoiding the accumulation of waste in the placing groove 28, preventing the waste from causing jamming to the movement of the supporting block 25, ensuring the positioning accuracy of the workpiece, thus improving the processing quality. And during the cleaning process, the collecting box 14 is always located at a position far from the blanking plate, avoiding the waste chips from being discharged into the collecting box 14. The automatic cleaning function reduces the frequency of the operator manually cleaning the placing groove 28, especially suitable for the production scenario of long-term continuous operation, and improves the production efficiency;It should be noted that a partial chip removal groove can be penetrated and opened at the discharging end of the processing table relative to the discharging plate 61, so as to discharge the waste chips to the bottom of the workbench 1.;

[0048] In this embodiment, as Figure 12 shown, a processing groove 26 is embedded in the supporting block 25, and a guiding groove 27 communicating with the processing groove 26 is penetrated through the supporting block 25. Specifically, the processing groove 26 is aligned with the tapping tool to ensure that the center of the tool is coaxial with the center of the threaded hole. The setting of the processing groove 26 provides a moving space for the processing of the tapping tool, and the setting of the guiding groove 27 facilitates the cleaning group to blow the waste chips in the processing groove 26 onto the discharging plate 61 for discharging.

[0049] Furthermore, in this embodiment, each device is controlled and driven by an external controller, and the linkage operation of each component is realized by setting specified working procedures and components such as sensors to ensure the normal operation of the overall device. Of course, the circuit connection and signal connection between each device and component are all prior arts and will not be described here.

[0050] Working principle:

[0051] In the initial state, the cylinder 19 is in a stationary state, the push plate 16 stops at the initial position, the collection box 14 is located away from the discharge plate 61, the support block is located in the fixed tooling 13, and its bottom is in contact with the inner bottom wall of the fixed tooling 13, and the abutment rod 22 is in contact with the fixed ring 4. When processing the flange nut, the flange nut is placed in the placement groove 28 through the handling device 2, and the bottom of the flange nut is in contact with the top of the support block 25. The external gear 3 is driven to rotate by the driving component 5, and the fixed tooling 13 rotates with the external gear 3 to the tapping station. The lifting device 17 drives the tapping device 11 to move downward to perform thread processing on the flange nut in the placement groove 28. After the tapping is completed, the external gear 3 continues to rotate to transfer the processed flange nut to the unloading station. As the outer gear 3 rotates, the abutment rod 22 abuts against the abutment block 10 and moves along the guide end face of the abutment block 10, so that the supporting block 25 slowly moves the processed flange nut out of the placement groove 28. When the abutment rod 22 moves to the center position of the horizontal end face of the abutment block 10, the outer gear 3 stops rotating, and the supporting block 25 pushes the flange nut out along the placement groove 28 and is arranged relative to the push plate 16. At this time, the blower 81 starts and discharges the air flow through the exhaust duct 82 to the exhaust cylinder 83, and discharges it from the air outlet of the exhaust cylinder 83 to the top of the fixed tooling 13, blowing away the waste chips on the fixed tooling 13. The blower 81 starts for a specified time and then stops, and then the cylinder 19 starts and drives the push plate 16 and the second rack 75 toward the flange nut on the placement groove 28. The nut moves, causing the second gear 76 to rotate with the movement of the second rack 75. Since the second gear 76 is sleeved on the first shaft 72, the first shaft 72 will also rotate accordingly. The first shaft 72 drives the second shaft 77 to rotate through the belt transmission mechanism 71, and the first gear 73 on the second shaft 77 also rotates. The first gear 73 drives the third gear 20 to rotate, and the third gear 20 drives the first rack 74 to move, so that the collection box 14 fixedly connected to the moving plate 18 slides in the moving groove 15 on the workbench 1 to the position corresponding to the discharge plate 61. As the cylinder 19 drives the push plate 16 to move, the push plate 16 pushes the flange nut on the top of the supporting block 25 onto the discharge plate 61, so that the flange nut flows to the collection groove. At the same time, When the cylinder 19 drives the second rack 75 to continue to move, the third gear 20 will continue to mesh with the convex tooth 29. At this time, the third gear 20 will drive the convex tooth 29 to push the movable plate 91 to squeeze the spring 94 through the movable rod 92. Due to the setting of the spring 94, the convex tooth 29 will reciprocate relative to the first rack 74, so that the first rack 74, the convex tooth 29 and the third gear 20 will always be in a meshing state. When the flange nut falls to the collection box 14, the cylinder 19 is reset, and the collection box 14 can be driven to reset at this time. After the cylinder 19 stops, the blower 81 is started, so that the waste chips on the component placement groove 28 and the supporting block 25 are blown away. The blower 81 stops running after running for a period of time. Finally, the driving component 5 drives the outer gear 3 to rotate.The new flange nut enters the tapping station for processing. Repeat the above steps to achieve the processing of the flange nut. The overall structure is simple to operate and has a high degree of automation. It can facilitate the loading and unloading of the flange nut during the rapid processing of the flange nut, reduce the downtime waiting time, and thus improve the processing efficiency of the flange nut.
