Description

Technical Field

[0001] The present invention relates to the technical field of screw part processing equipment, and in particular to a fully automatic tapping machine for anti-corrosion grid nails. Background Art

[0002] Anti-corrosion grid nails generally refer to grid nails that have undergone anti-corrosion treatment and are used for fixing and installing anti-corrosion grids. They are usually processed from anti-corrosion materials such as galvanized, hot-dip galvanized, or stainless steel to improve their corrosion resistance and extend their service life. These anti-corrosion grid nails are commonly used in outdoor, humid environments, or occasions where anti-corrosion performance is required, such as industrial sites like docks, chemical plants, and sewage treatment plants. For anti-corrosion grid nails, it is generally necessary to tap their interior. Tapping the interior can ensure that the grid nails can firmly connect and fix the grid plates during use, enhancing the structural stability and safety. Therefore, a fully automatic tapping machine is used for tapping. At the same time, the purpose of tapping is to form threads at one end of the grid nail so that it can be combined with other components (such as bolts, nuts, etc.) during installation to provide a better connection effect.

[0003] In the prior art, a Chinese patent document with the publication number CN114515873B proposed a fully automatic tapping machine for metal manufacturing, including a workbench. A clamping mechanism is installed on the upper surface of the workbench, and a lifting mechanism is installed at the left position on the upper surface of the workbench. A main body is fixedly installed on the moving rod of the lifting mechanism. A drill bit is movably installed inside the main body, and the threaded section of the drill bit extends out of the main body. Although this technology, through the setting of the fixed ball and the contact ball, avoids the drill bit continuing to tap when the tapping resistance is large, resulting in its breakage inside the workpiece and affecting the processing efficiency of subsequent workpieces, it is the same as the traditional method in that when using anti-corrosion grid nails outdoors, due to the need to adapt to diverse sites, there are various grid nail models with different specifications and diameters. This requires using taps with different specifications and diameters for tapping operations. When the traditional tapping machine faces grid nails with different specifications and diameters, it is necessary to frequently change tools or adjust the equipment, which not only increases the downtime and adjustment costs of the production line but also reduces the production efficiency. At the same time, because different types of taps are used, it is also relatively troublesome to search for and replace the taps when changing them. In addition, traditional taps generate iron chips during tapping. After tapping, because the outside of the tap is provided with tooth grooves, and the iron chips dropped during tapping are spiral, some iron chips will hang in the tooth grooves of the tap. This will not only cause iron chips to adhere to the outside of the tap, affecting the effect of the next tapping, but also the residue of the iron chips will cause incomplete tapping or slipping of the threads, thereby affecting the tapping effect and service life of the tap.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting up a tapping assembly, it is possible to adapt to the production needs of grille nails of different specifications, and has strong applicability and flexibility, while avoiding the trouble of frequent replacement of taps in the traditional way. When encountering large-sized grille nails, the rotating drum is rotated to cause the positioning plate to rotate. At this time, the positioning column will move along the track of the arc groove, and at the same time, the positioning column will drive one end of the sliding rod away from the inside of the positioning plate, thereby causing the four straight groove taps to move away from each other. At this time, the spacing between the four straight groove taps will change, which is suitable for tapping large-sized grille nails. At the same time, the diameter of the tap is adjusted by setting a rotating drum to adapt to tapping of grille nails of different specifications. This is not only convenient and fast, but also improves production efficiency, and also saves the cost of producing taps of different specifications.

[0016] By setting the positioning component, the position of the straight groove tap can be positioned, which facilitates the tapping of the straight groove tap and ensures the accuracy and consistency of the tapping. Before rotating the rotating drum, it is necessary to press the pressing drum to move downward and squeeze the spring at the same time. At this time, the top of the sloped hole will continuously squeeze one side of the second ball block to roll downward, and at the same time, the other side of the second ball block will follow the hole of the second arc hole to push the clamping column upward, thereby prompting the adapter hole at the bottom of the clamping column to drive the first ball block away from the inside of the first arc hole, thereby releasing the limit on the positioning rod. At this time, by rotating the toggle plate, it is convenient to tap the straight groove tap. To adjust the cone, when positioning the straight groove tap, you only need to release the limit of the pressing cylinder to prompt the extrusion spring to rebound, and then prompt the sloped hole to return to its position. At this time, the first ball block will be stuck in the hollow of the first arc hole again, thereby prompting the position of the positioning rod to be fixed, and the position of the straight groove tap is fixed at the same time. In this way, when the motor drives the connecting shaft to rotate, the position of the positioning rod can be fixed through the action of the first ball block. At the same time, the positioning plate will rotate synchronously when the positioning plate rotates, thereby facilitating the tapping of the straight groove tap and avoiding the problem of displacement of the position of the straight groove tap when the straight groove tap rotates.

[0017] By setting up a cleaning component, the iron chips on the outside of the straight groove tap can be cleaned to ensure the integrity of the straight groove tap during tapping, and avoid the problem of iron chips hanging on the outside of the straight groove tap during traditional tapping, resulting in incomplete tapping or slipped threads during tapping of the straight groove tap. When in use, the pull rod drives the extrusion plug to move upward, and at this time, the external air enters the inside of the air cylinder from the suction pipe. At this time, when the moving pull rod drives the extrusion plug to move downward, the gas inside the air cylinder will be transmitted from the outlet pipe to the alignment pipe, and blown to the straight groove tap at the same time, thereby prompting the iron chips on the outside of the straight groove tap to be cleaned up, thereby facilitating the next tapping of the straight groove tap.

[0018] By setting the driving component, the cleaning component can be automatically driven to clean the straight flute tap. When the lifting cylinder drives the straight flute tap to tap downward, the slide plate will drive the first rack to move downward. At this time, through the action of the gear, the second rack will drive the pull rod to move upward. At this time, external air will enter the air cylinder from the suction pipe. At the same time, when the straight flute tap taps to the lowest end of the grid nail, the top of the extrusion plug will squeeze the return bolt to move into the resistance cylinder. At this time, the return spring will rebound, prompting the block to move downward. At this time, the T-shaped groove will be adapted to the T-shaped block, and at the same time, the hole-blocking spring will rebound, prompting the baffle to move to the top of the suction pipe, thus facilitating the air outlet of the air outlet pipe next time. At this time, when the tapping is completed, the straight flute tap moves upward, and at the same time, it prompts the second rack to drive the pull rod to move downward, and then prompts the gas inside the air cylinder to be input into the alignment pipe from the air outlet pipe, and then blows to the straight flute tap, so as to blow off the iron chips outside the straight flute tap. At the same time, by setting the alignment pipe to be fixedly connected to one side of the slide plate through the connecting plate, it is further prompted that the alignment pipe can always move along with the movement of the tap, thus facilitating the blowing of the straight flute tap when it rises.

[0025] The tapping assembly provided can adapt to the production needs of grille nails of different specifications, has strong applicability and flexibility, and avoids the trouble of frequent replacement of taps in the traditional way. When encountering grille nails of large specifications, rotate the rotating drum 16 to cause the positioning plate 15 to rotate. At this time, the positioning column 13 will move along the track of the arc groove 12. At the same time, the positioning column 13 will drive one end of the slide rod 10 away from the inside of the positioning plate 9, thereby causing the four straight groove taps 14 to move away from each other. At this time, the spacing between the four straight groove taps 14 will change, which is suitable for tapping large-sized grille nails. At the same time, the diameter of the tap is adjusted by setting the rotating drum 16 to be suitable for tapping grille nails of different specifications. This is not only convenient and fast, but also improves production efficiency, and also saves the cost of producing taps of different specifications.

[0026] like Figures 1 to 9 As shown, the top end of the connecting shaft 8 passes through the interior of the positioning rod 17, the clamping column 22 and the pressing cylinder 28 and is fixedly connected to the output end of the motor 6 passing through the interior of the fixing column 7. There are four straight groove taps 14, and one side of the bottom of the four straight groove taps 14 is provided with tapping teeth, and the shape of the four straight groove taps 14 combined together is circular.

[0027] The connection shaft 8 is provided to facilitate the connection between the positioning plate 9 and the output end of the motor 6, thereby facilitating the tapping of the straight groove tap 14 in the later stage. At the same time, the positioning rod 17 is fixed by the first ball block 21, thereby limiting the rotation of the positioning disk 15. Therefore, when the connecting shaft 8 rotates, the first ball block 21 will drive the positioning rod 17 to rotate synchronously, which not only facilitates the rotation of the straight groove tap 14 driven by the positioning plate 9 and facilitates the tapping of the straight groove tap 14, but also prompts the positioning disk 15 to rotate, thereby avoiding the problem of sliding of the slide bar 10 when the straight groove tap 14 is tapping.

[0028] like Figures 1 to 7As shown, both sides of the bottom of the card column 22 are provided with matching holes 20, and the first ball block 21 is slidably connected inside the matching hole 20, and both sides of the top of the positioning rod 17 are provided with first arc holes 18. The bottom of the fixed cylinder 19 has a conical shape, and one side of the first ball block 21 contacts one side of the matching hole 20, and the other side of the first ball block 21 contacts the inner wall of the bottom of the fixed cylinder 19. The specification and size of the first arc hole 18 are adapted to the specification and size of the first ball block 21. A toggle plate is also fixedly connected to one side of the positioning rod 17, and the outside of the bottom of the card column 22 contacts the inner wall of the fixed cylinder 19. The top of the card column 22 is provided with second arc holes 2 4. A partition plate 23 is fixedly connected to the inner wall of the top of the fixed cylinder 19, and second ball blocks 25 are slidably engaged with the tops of both ends of the partition plate 23. The top of one side of the second ball block 25 contacts the inner part of the top of the second arc-shaped hole 24, and the other side of the second ball block 25 contacts the inner wall of the fixed cylinder 19. The specification and size of the second ball block 25 are matched with the specification and size of the second arc-shaped hole 24, and the position of the second ball block 25 corresponds to the position of the second arc-shaped hole 24. A sloped hole 26 is provided at the bottom of the pressing cylinder 28, and the bottom of the sloped hole 26 contacts the top of the second ball block 25. The inner part of the top of the clamping column 22 is slidably engaged with the outer part of the top of the connecting shaft 8.

[0029] The positioning assembly is provided to position the straight groove tap 14, which facilitates the tapping of the straight groove tap 14 and ensures the accuracy and consistency of the tapping. Before rotating the rotating drum 16, it is necessary to press the pressing cylinder 28 to move downward, and at the same time, the squeezing spring 27 is squeezed. At this time, the top of the sloped hole 26 will continuously squeeze one side of the second ball block 25 to roll downward, and at the same time, the other side of the second ball block 25 will move upward along with the hole of the second arc hole 24 to push the clamping column 22, thereby prompting the adapter hole 20 at the bottom of the clamping column 22 to drive the first ball block 21 away from the inside of the first arc hole 18, thereby releasing the limit of the positioning rod 17. At this time, by rotating the toggle plate on one side of the positioning rod 17, the adjustment of the straight groove tap 14 is facilitated. When positioning the straight groove tap 14, it is only necessary to release the limit of the pressing cylinder 28 to prompt the squeezing spring 27 to rebound, thereby prompting the sloped hole 26 to return to its position. At this time, the first ball block 21 will be stuck in the hollow of the first arc hole 18 again, and then This causes the position of the positioning rod 17 to be fixed, and at the same time the position of the straight groove tap 14 to be fixed. In this way, when the motor 6 drives the connecting shaft 8 to rotate, through the action of the first ball block 21, when the positioning plate 9 rotates, the connection between the latch 29 and the alignment cylinder 30 is released, and the first ball blocks 21 slidably engaged on both sides of the clamping column 22 and the first arc holes 18 are provided on both sides of the top of the positioning rod 17, so that the first ball block 21 is again engaged with the inside of the first arc hole 18, and at this time, the position of the positioning rod 17 is limited. At this time, by setting the inside of the top of the clamping column 22 to be slidably engaged with the outside of the top of the connecting shaft 8, when the connecting shaft 8 drives the clamping column 22 to rotate, due to the engagement of the first ball block 21 with the first arc hole 18, the first ball block 21 will drive the positioning rod 17 to rotate, thereby causing the positioning rod 17 to drive the positioning disk 15 to rotate synchronously through the rotating cylinder 16, thereby avoiding the problem that when the straight groove tap 14 rotates, the sliding rod 10 moves, causing the position of the straight groove tap 14 to be displaced.

[0030] like Figures 4 to 6 As shown, the outside of the top of the pressing cylinder 28 is fixedly connected to a fixing ring, the bottom of the fixing ring is fixedly connected to a bolt 29, one side of the top of the fixing cylinder 19 is fixedly connected to an alignment cylinder 30, the inside of the alignment cylinder 30 is slidably connected to a pull bolt 31, an inclined angle is provided on one side of the bottom of the bolt 29, a slot is provided on the top of the inclined angle of the bolt 29, a spring is fixedly connected to the inside of one end of the alignment cylinder 30, the spring is sleeved on the outside of the pull bolt 31, and the other end of the spring is fixedly connected to the outside of one end of the pull bolt 31, a hole is provided on the top of the alignment cylinder 30, the position of the hole corresponds to the position of the bolt 29, and the position of one end of the pull bolt 31 corresponds to the position of the hole on the top of the alignment cylinder 30.

[0031] By means of the provided alignment cylinder 30 and the latch bolt 29, when the fixing ring is pressed to cause the pressing cylinder 28 to drive the latch bolt 29 to move downward, the bottom of the latch bolt 29 will be stuck in the latch hole at the top of the alignment cylinder 30. At this time, the bottom end of the latch bolt 29 will squeeze one end of the pull bolt 31 to move outward. At the same time, when the bottom end of the plug 29 moves past the pull bolt 31, one end of the pull bolt 31 will be stuck in the slot by virtue of the spring rebound effect, thereby causing the position of the pressing cylinder 28 to be fixed, thereby facilitating the rotation of the positioning rod 17 and causing the four straight groove taps 14 to change the pitch. At the same time, when the limit on the latch bolt 29 is released, one end of the pull bolt 31 is pushed to cause the other end of the pull bolt 31 to move away from the slot, causing the fixing ring to automatically return to its position as the extrusion spring 27 rebounds, thereby facilitating the fixation of the positioning rod 17 by the first ball block 21.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 8 and Figure 9 As shown, a connecting plate is fixedly connected to the top of the alignment tube 39, and one end of the connecting plate away from the alignment tube 39 is fixedly connected to one side of the slide plate 5. The alignment tube 39 has an inclined shape, and the height of the lowest end of the alignment tube 39 is higher than the top of the straight groove tap 14. The length of the hose 38 is greater than the distance when the straight groove tap 14 moves downward.

[0033] By means of the cleaning assembly, the iron filings on the outside of the straight groove tap 14 can be cleaned to ensure the integrity of the straight groove tap 14 during tapping, and avoid the problem that the iron filings are hung on the outside of the straight groove tap 14 during traditional tapping, resulting in incomplete tapping or slipped threads during tapping of the straight groove tap 14. When in use, the pull rod 40 drives the extrusion plug 41 to move upward, and at this time, the external air enters the interior of the air cylinder 35 from the suction pipe 36. At this time, when the moving pull rod 40 drives the extrusion plug 41 to move downward, the gas inside the air cylinder 35 will be transmitted from the outlet pipe 37 to the alignment pipe 39, and blown toward the straight groove tap 14 at the same time, thereby prompting the iron filings on the outside of the straight groove tap 14 to be cleaned up, thereby facilitating the next tapping of the straight groove tap 14.

[0034] like Figures 1 to 9As shown, a rotating rod is rotatably connected to the middle of the gear 33 through a shaft. One end of the rotating rod away from the gear 33 is fixedly connected to one side of the top of the fixed rod 2. The lengths of the first rack 32 and the second rack 34 are greater than the distance when the straight flute tap 14 moves downward. Two holes are opened at the bottom inside the air cylinder 35. The bottoms of the two holes are respectively communicated with the input ports of the suction pipe 36 and the air outlet pipe 37. The specification size of the baffle 42 is greater than the specification size of the hole. The position of the track plate 45 corresponds to the position of the hole. A T-shaped block 43 is fixedly connected to the top of the baffle 42. One end of the top of the T-shaped block 43 is provided with a slope angle. A first connecting frame is fixedly connected to the bottom inside the air cylinder 35. A placing cylinder 44 is fixedly connected to the top of the first connecting frame. A blocking block 48 is slidably connected inside the placing cylinder 44. One side of the bottom of the blocking block 48 is provided with an oblique angle. The position of the oblique angle at the bottom of the blocking block 48 corresponds to the position of the slope angle at the top of the T-shaped block 43. A T-shaped groove 54 is opened at the bottom of the blocking block 48. The specification size of the T-shaped groove 54 is adapted to the specification size of the T-shaped block 43. A return spring 47 is fixedly connected to the top end of the blocking block 48. The top end of the return spring 47 is fixedly connected to the top inside the placing cylinder 44. A resisting cylinder 51 is fixedly connected to the top inside the air cylinder 35 through a second connecting frame. A return bolt 52 is slidably connected inside the resisting cylinder 51. A resilient spring 53 is fixedly connected to the top of the return bolt 52. The top end of the resilient spring 53 is fixedly connected to the top inside the resisting cylinder 51. A towing rope 50 is also fixedly connected to the top of the blocking block 48. One end of the towing rope 50 away from the blocking block 48 passes through the inside of the return spring 47, the side wall of the air cylinder 35 and the inside of the resilient spring 53 and is fixedly connected to the top of the return bolt 52 through a plurality of pulleys. When the extrusion plug 41 moves to the top of the placing cylinder 44, the pull rope 49 is in a taut state. When the T-shaped block 43 moves to the top of the air outlet pipe 37, the top of the T-shaped block 43 contacts one side of the bottom of the blocking block 48.

[0035] By means of the provided driving component, it is possible to achieve the function of automatically driving the cleaning component to clean the straight flute tap 14. When the lifting cylinder 3 drives the straight flute tap 14 to tap downwards, the slide plate 5 will drive the first rack 32 to move downwards. At this time, through the action of the gear 33, the second rack 34 will drive the pull rod 40 to move upwards. At this time, external air will enter the air cylinder 35 from the suction pipe 36. At the same time, when the straight flute tap 14 taps to the lowest end of the grid nail, the top of the extrusion plug 41 will squeeze the return bolt 52 to move into the resisting cylinder 51. At this time, the return spring 47 will rebound, prompting the stop block 48 to move downwards. At this time, the T-shaped groove 54 will be adapted to the T-shaped block 43. At the same time, the hole-blocking spring 46 rebounds, prompting the baffle 42 to move to the top of the suction pipe 36, thus facilitating the air outlet of the air outlet pipe 37 next time. At this time, when the tapping is completed, the straight flute tap 14 moves upwards, and at the same time, it prompts the second rack 34 to drive the pull rod 40 to move downwards. Further, it prompts the gas inside the air cylinder 35 to be input into the alignment pipe 39 from the air outlet pipe 37, and then blown towards the straight flute tap 14, thereby prompting the iron chips outside the straight flute tap 14 to be blown off. At the same time, by setting the alignment pipe 39 to be fixedly connected to one side of the slide plate 5 through the connecting plate, it is further prompted that the alignment pipe 39 can always move following the movement of the tap, thus facilitating the blowing of air to the straight flute tap 14 when the straight flute tap 14 rises. At the same time, by setting the length of the hose 38 to be greater than the distance when the straight flute tap 14 moves downwards, it is further prompted that the hose 38 can follow the movement of the alignment pipe 39, thus facilitating the alignment pipe 39 to always blow air to the straight flute tap 14. At the same time, when the extrusion plug 41 moves to the top of the placement cylinder 44, the pull rope 49 is in a taut state and when the T-shaped block 43 moves to the top of the air outlet pipe 37, the top of the T-shaped block 43 contacts one side of the bottom of the stop block 48. When the extrusion plug 41 moves away from the return bolt 52, the rebound spring 53 rebounds, and at the same time, it pulls one end of the traction rope 50 to drive the stop block 48 to move upwards, thereby prompting the bevel angle at the bottom of the baffle 42 to correspond to the slope angle at the top of the T-shaped block 43. After that, when the extrusion plug 41 moves to the top of the placement cylinder 44 and the pull rope 49 is in a taut state, the straight flute tap 14 has moved away from the inside of the grid nail. At this time, it is convenient for the alignment pipe 39 to clean the straight flute tap 14. At the same time, when the lifting cylinder 3 drives the straight flute tap 14 to further move away from the top of the grid nail, the extrusion plug 41 will further descend, thereby prompting the pull rope 49 to pull the T-shaped block 43 to move. At this time, by setting the bevel angle at the bottom of the stop block 48 and the slope angle at the top of the T-shaped block 43, the baffle 42 will pass through the bottom of the stop block 48, thereby prompting the baffle 42 to block the input port of the air outlet pipe 37. At the same time, the other end of the T-shaped block 43 will abut against one side of the bottom of the stop block 48, thereby limiting the movement of the baffle 42, and at the same time, it is convenient for the later extrusion plug 41 to suck air into the inside of the air cylinder 35 from the suction pipe 36.

[0036] The working principle provided by the present invention is that, firstly, the tapping assembly is provided to adapt to the production needs of grille nails of different specifications, and has strong applicability and flexibility, while avoiding the trouble of frequent replacement of taps in the traditional way. When encountering grille nails of large specifications, the rotary drum 16 is rotated to cause the positioning plate 15 to rotate, and then the positioning column 13 will move along the track of the arc groove 12, and at the same time, the positioning column 13 will drive one end of the slide bar 10 away from the inside of the positioning plate 9, thereby causing the four straight groove taps 14 to move away from each other. At this time, the spacing between the four straight groove taps 14 will change, and then it is suitable for tapping grille nails of large specifications. At the same time, the diameter of the tap is adjusted by providing the rotating rotary drum 16 to be suitable for tapping grille nails of different specifications. It is not only convenient and fast, but also improves production efficiency, and also saves the cost of producing taps of different specifications. Afterwards, the positioning component is set to play the role of positioning the straight groove tap 14, which facilitates the tapping of the straight groove tap 14 and ensures the accuracy and consistency of the tapping. Before rotating the rotating cylinder 16, it is necessary to press the pressing cylinder 28 to move downward, and at the same time, the squeezing spring 27 is squeezed. At this time, the top of the sloped hole 26 will continuously squeeze one side of the second ball block 25 to roll downward, and at the same time, the other side of the second ball block 25 will follow the hole of the second arc hole 24 to push the clamping column 22 upward, thereby prompting the adapter hole 20 at the bottom of the clamping column 22 to drive the first ball block 21 away from the inside of the first arc hole 18, thereby releasing the limit of the positioning rod 17. At this time, by rotating the toggle plate, it is convenient to tap the straight groove tap 14. The adjustment of the cone 14, when positioning the straight groove tap 14, only needs to release the limit of the pressing cylinder 28, so that the extrusion spring 27 rebounds, and then the sloped hole 26 returns to its position, and then the first ball block 21 will be stuck in the hollow of the first arc hole 18 again, so that the position of the positioning rod 17 is fixed, and the position of the straight groove tap 14 is fixed at the same time. In this way, when the motor 6 drives the connecting shaft 8 to rotate, the position of the positioning rod 17 can be fixed by the action of the first ball block 21, and the positioning plate 15 will rotate synchronously when the positioning plate 9 rotates, so as to facilitate the tapping of the straight groove tap 14 and avoid the problem of displacement of the position of the straight groove tap 14 when the straight groove tap 14 rotates; Then, through the provided cleaning component, the iron filings outside the straight flute tap 14 can be cleaned, ensuring the integrity of the straight flute tap 14 during tapping, and avoiding the problem that iron filings hang on the outside of the straight flute tap 14 during traditional tapping, which may cause incomplete tapping or thread slipping of the straight flute tap 14. During use, the pull rod 40 drives the extrusion plug 41 to move upward. At this time, external air enters the inside of the air cylinder 35 from the air suction pipe 36. When the pull rod 40 is driven to move the extrusion plug 41 downward, the gas inside the air cylinder 35 will be transmitted from the air outlet pipe 37 to the alignment pipe 39 and blown towards the straight flute tap 14 at the same time, thereby facilitating the cleaning of the iron filings outside the straight flute tap 14 and making it convenient for the next tapping of the straight flute tap 14. Finally, through the provided driving component, the cleaning component can be automatically driven to clean the straight flute tap 14. When the lifting air cylinder 3 drives the straight flute tap 14 to tap downward, the sliding plate 5 will drive the first rack 32 to move downward. At this time, through the action of the gear 33, the second rack 34 will drive the pull rod 40 to move upward. At this time, external air will enter the air cylinder 35 from the air suction pipe 36. At the same time, when the straight flute tap 14 taps to the lowest end of the grid nail, the top of the extrusion plug 41 will squeeze the return bolt 52 to move into the blocking cylinder 51. At this time, the return spring 47 will rebound, causing the blocking block 48 to move downward. At this time, the T-shaped groove 54 will be adapted to the T-shaped block 43, and at the same time, the hole-blocking spring 46 will rebound, causing the baffle plate 42 to move to the top of the air suction pipe 36, thus facilitating the air outlet of the air outlet pipe 37 next time. When the tapping is completed, the straight flute tap 14 moves upward, and at the same time, it causes the second rack 34 to drive the pull rod 40 to move downward, thereby causing the gas inside the air cylinder 35 to be input from the air outlet pipe 37 to the alignment pipe 39 and blown towards the straight flute tap 14, so as to blow off the iron filings outside the straight flute tap 14. At the same time, through the provided alignment pipe 39 being fixedly connected to one side of the sliding plate 5 through a connecting plate, the alignment pipe 39 can move along with the movement of the tap at all times, thus facilitating the blowing of the straight flute tap 14 when it rises.
