[0002] The tapping machine is a processing machine used to perform tapping, threading and threading for hardware products, realizing automation and reducing labor costs. The threaded holes can be drilled by rotating the tapping machine. When the existing automatic tapping machine performs rotary tapping, the tapping tap rotates to drill holes on the surface of the workpiece. However, when the current tapping tap is rotating and drilling, iron filings will be left inside the thread hole.

However, when using this method, there is still a problem, that is, when it is stuck in the groove and cannot be blown out under a certain wind force, it will still affect the drilling. In order to solve this problem, it cannot be solved by increasing the blowing power, because the iron filings are irregular and have many sharp parts, and the sharp parts can easily fit on the side wall of the groove and form a stop. Therefore, in response to the above-mentioned problems, there is an urgent need for a more effective cleaning method for the iron filings formed by the tapping machine during the automatic tapping process.

[0009] As a further solution of the present invention: wherein, the two groups of through holes arranged on the cylindrical box are designed to be adjacent to each other, and one group of the through holes is arranged at a position corresponding to the position of the tapping machine, and the other group of the through holes is arranged in the direction of rotation of the circular turntable.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The rotation of the circular turntable will continuously make the docking holes and grooves correspond to the blow pipe and the tapping head in rotation. When the docking holes correspond to the blow pipe, the air pump will work, and then the gas will enter the cylindrical box through the docking holes. The gas in the cylindrical box will enter the groove connected to it through the through hole, and then blow away the iron filings in the groove.

[0018] 2. The through holes set above correspond to the grooves corresponding to the tapping head and the previous position, and the positions are fixed. Because a lot of iron filings will be generated during the tapping process of the tapping head, at this time, just pump in the gas to blow the iron filings away. Because it cannot be guaranteed that the iron filings can be completely removed in the first groove, a gas outlet function is also set in the direction of rotation of the circular turntable and in the adjacent grooves. After the tapping is completed, the groove will come to the next position with the rotation of the circular turntable. There will still be a through hole, and it will continue to be flushed by gas to double blow away the iron filings in the groove. Thereby, on the one hand, high utilization of gas is achieved, and on the other hand, double blowing of iron filings can be guaranteed.

[0019] 3. By sliding the rotating shaft outward inside the sliding groove, the rotating shaft can rotate under the action of the ring gear and the toothed plate, thereby driving the toggle wheels on both sides to rotate. The toggle pieces on the toggle wheels will rotate inside the groove, thereby moving the spiked iron filings attached to the inner wall of the groove, and then blowing them away with gas.

[0020] 4. Rotate the groove to the position with the through hole, and let the gas in with the help of the air pump. The gas will enter the sealed chamber through the through hole and the air outlet. The pressure of the sealed chamber will increase with the introduction of gas, pushing the movable rod to slide inside the sealed chamber, and then cooperate with the connecting rod and the rotating ring to drive the rotating shaft to move forward. During the movement, the rotating shaft can be rotated with the help of the ring gear and the toothed plate. Then the effect of automatic rotation is achieved. After the gas is interrupted, the air pressure disappears, and the driving force of the movable rod disappears. At this time, a reset spring can be set on the connecting rod, and the reset spring can help the movable rod to reset quickly. It is convenient for recycling. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] See also Figure 1, which is a schematic diagram of the feeding and tapping structure of the tapping machine in this embodiment, the structure includes a fixed base plate 10, and a circular turntable 20 installed on the fixed base plate 10, a floating nut feeding mechanism 30 is arranged on the right side of the circular turntable 20, and a collecting mechanism 40 is arranged on the left side of the circular turntable 20, the collecting mechanism 40 can collect the floating nuts that have been tapped, a support frame 50 is fixedly installed at the rear end of the fixed base plate 10, the circular turntable 20 rotates under the support frame 50, and a positioning mechanism 60 is arranged on the opposite surface of the support frame 50, the positioning mechanism 60 is slidably connected to the fixed base plate 10, the circular turntable 20 rotates on the fixed base plate 10, and eight grooves 21 are opened on the circular turntable 20. In this embodiment, when the floating nut falls from the feeding mechanism 30 into the groove 21 of the circular turntable 20, the floating nut in the groove 21 will be fixed and positioned under the action of the positioning mechanism 60. At this time, the floating nut that has been positioned and fixed will be tapped by the tapping head. In actual use, the tapping point will be flushed with lubricating oil. The floating nut that has been tapped will enter the next direction as the circular turntable 20 rotates. The tapping head will continue to process subsequent floating nuts. When the floating nut after tapping enters the collecting mechanism 40, it will be automatically dialed into the collecting mechanism 40 by the dialing mechanism to complete the collection, thereby achieving the integrated automation effect of automatic tapping and automatic collection.

[0034] like Figure 2 As shown, in order to better process the iron filings generated by the tapping head, the circular turntable 20 includes a disc 1 22 and a disc 2 23, and the disc 1 22 and the disc 2 23 are fixedly connected and rotate synchronously; a circle of multiple groups of docking holes 221 evenly distributed are arranged on the disc 1 22, and the number of the docking holes 221 is eight, and a blow pipe (not shown in the figure) is fixedly installed on the fixed bottom plate 10, and the position of the blow pipe is fixed. When the docking hole 221 rotates to the bottom of the blow pipe, the blow pipe will be connected with the docking hole 221, and the air pump will blow air to it. In order to allow the gas to enter the groove 21, an air outlet 211 is provided in the groove 21. Therefore, in this embodiment, the gas can be pumped into the groove 21 through the air pump through the blow pipe and the docking hole 221 and the air outlet 211, so as to complete the blowing away of the iron filings in the groove 21. However, the effect of only using gas to blow away is often not good, so the following improvements are also made.

[0035] like Figure 3 and Figure 4As shown, the circular turntable 20 is provided with a ventilation mechanism 70 inside, and the ventilation mechanism 70 includes a cavity 71 opened inside the circular turntable 20, and a cylindrical box 72 is fixedly installed inside the cavity 71. The circular turntable 20 is rotatably connected with the cylindrical box 72, and the cylindrical box 72 is connected with the docking hole 221 opened on the disk 22. When the air blow pipe is docked with the docking hole 221, the gas is pumped into the cylindrical box 72, and then the gas is discharged into the groove 2 through the outlet hole 211 through the cylindrical box 72. 1; however, if the gas pumped into the cavity 71 from the blowing pipe can be discharged from all the gas outlets 211, it will affect the gas outlet speed of each gas outlet 211 on the one hand, and cause gas waste on the other hand, because when the circular turntable 20 is in use, only four grooves 21 are put into operation at the same time, and the other four are in the preparation stage. Moreover, among the four grooves 21 put into operation, only the middle two need to be processed with iron filings, so it is only necessary to ensure that these two grooves 21 can discharge gas. Therefore, if Fig. 9 As shown, two groups of through holes 721 are provided on the side wall of the cylindrical box 72, and a group of through holes 722 communicating with the docking hole 221 is also provided on the top of the cylindrical box 72. The position of the through holes 722 corresponds to the position of the air blowing pipe. Whenever the docking hole 221 rotates to the position of the through holes 722, the gas in the air blowing pipe can be transmitted to the cavity 71. In this embodiment, the rotation of the circular turntable 20 will continuously make the docking hole 221 and the groove 21 correspond to the rotation of the air blowing pipe and the tapping head. When the docking hole 221 corresponds to the air blowing pipe, the air pump will work, and then the generated gas will enter the cylindrical box 72 through the docking hole 221, and the gas in the cylindrical box 72 will enter the groove 21 connected to it through the through holes 721, and then blow away the iron filings in the groove 21.

[0036] It is worth noting that the through hole 721 arranged above corresponds to the groove 21 corresponding to the tapping head and the previous position, respectively, and the position is fixed. Because a lot of iron filings will be generated during the tapping process of the tapping head, at this time, as long as the gas is pumped in, the iron filings will be blown away. Because it cannot be guaranteed that the iron filings can be completely removed in the first groove 21, a gas outlet function is also provided in the direction of rotation of the circular turntable 20 and in the adjacent grooves 21. After the tapping is completed, the groove 21 will come to the next position as the circular turntable 20 rotates, and the through hole 721 will still exist, and will continue to be purged by the gas to double blow away the iron filings in the groove 21. Thereby, on the one hand, a high utilization rate of the gas is achieved, and on the other hand, double cleaning of the iron filings can be guaranteed.

[0037] However, there is still a problem in the above process. Since the iron filings have a plurality of sharp spikes, the presence of the sharp spikes will cause the iron filings to stick to the groove 21. Therefore, in order to solve the problem of the iron filings piercing into the groove 21, the following improvements are made.

[0038] like Figure 5 and Figure 6 As shown, a propulsion mechanism 80 and a scraping mechanism 90 rotating inside the groove 21 are provided inside the groove 21. Figure 5 As shown, the scraper mechanism 90 includes a rotating shaft 91, a sliding groove 212 is provided on the side wall of the groove 21, both sides of the rotating shaft 91 are inserted into the sliding groove 212, and a ring gear 92 is fixedly installed at the end point of the rotating shaft 91, and a tooth plate 213 meshingly connected with the ring gear 92 is provided inside the sliding groove 212, and a toggle wheel 93 is fixedly installed on both sides of the rotating shaft 91 and outside the sliding groove 212, and a circle of toggle pieces 94 are provided on the toggle wheel 93. In this embodiment, by sliding the rotating shaft 91 outward inside the sliding groove 212, the rotating shaft 91 can be rotated under the action of the ring gear 92 and the tooth plate 213, thereby driving the toggle wheels 93 on both sides thereof to rotate, and the toggle pieces 94 on the toggle wheel 93 will rotate inside the groove 21, so that the spiked iron filings attached to the inner wall of the groove 21 can be toggled, and then blown away by gas.

[0039] like Figure 7 and Figure 8 As shown, the propulsion mechanism 80 includes a sealing chamber 81 disposed in the groove 21 and close to the side of the air outlet 211. The sealing chamber 81 is connected to the air outlet 211 through a connecting pipe 82. When the air outlet 211 is ventilated, air will enter the sealing chamber 81. The inside of the sealing chamber 81 is slidably connected with a movable rod 83. The movable rod 83 is fixedly installed with a connecting rod 84 on the side close to the rotating shaft 91. The connecting rod 84 is connected with a rotating ring 85 provided on the rotating shaft 91. In this embodiment, the groove 21 is rotated to the position with the through hole 721, and the gas is introduced in cooperation with the action of the air pump. When the gas passes through the through hole 721 and the air outlet 211, it will enter the sealing chamber 81. The pressure of the sealing chamber 81 will increase with the introduction of gas, pushing the movable rod 83 to slide inside the sealing chamber 81, and then cooperate with the connecting rod 84 and the rotating ring 85 to drive the rotating shaft 91 to move forward. During the movement, the action of the ring gear 92 and the tooth plate 213 can realize the rotation of the rotating shaft 91. Then the effect of automatic rotation is achieved. When the gas supply is interrupted, the gas pressure disappears, and the driving force of the movable rod 83 disappears. At this time, a reset spring can be provided on the connecting rod 84, and the reset spring can help the movable rod 83 to quickly reset, so as to facilitate recycling.

[0040] In summary, in order to ensure the smooth movement of the rotating shaft 91, the two sides of the rotating shaft 91 are symmetrically designed, wherein the connecting pipe 82 is as shown in FIG. Fig.10 As shown, when the gas passes through the air outlet 211, it will pass through the connecting pipes 82 at both ends and enter the sealing chambers 81 on both sides of the groove 21, thereby providing the same thrust to the movable rods 83 at both ends, thereby ensuring the uniformity of movement on both sides of the rotating shaft 91; avoiding the problem of deflection caused by asymmetric force on the left and right sides of the rotating shaft 91 during movement.

[0041] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
