Description

Technical Field

[0001] The present invention relates to the technical field of mechanical manufacturing, and particularly to a punching and tapping device for the manufacture of mechanical and electrical equipment. Background Art

[0002] In the manufacture of mechanical and electrical equipment, precise and efficient threaded connections are crucial to ensure the reliability and durability of the equipment. The punching and tapping device is used to create holes and internal threads in metal or other materials, and the performance of the device directly affects the product quality and production efficiency. High-performance devices can guarantee precision.

[0003] Chinese Patent with Patent Publication No. CN222243537U discloses a punching and tapping device for the manufacture of mechanical and electrical equipment. This patent mainly includes an equipment body and a punching and tapping assembly installed on the equipment body. The punching and tapping assembly includes an electric push rod vertically installed on the equipment body. The output end of the electric push rod faces downward and is equipped with a mounting frame. A bidirectional motor is movably arranged inside the mounting frame. Drill rods and taps are respectively installed at the two output ends of the bidirectional motor. Rotating rods located on the same horizontal line are fixed on both sides of the bidirectional motor facing away from each other. Both rotating rods are rotatably installed on the mounting frame. A driving motor with an output end fixed to one of the rotating rods is arranged on the mounting frame. By respectively installing drill rods and taps at the two output ends of the bidirectional motor, this patent can achieve rapid conversion between drilling and tapping, and the drill rods and taps are located on the same axis, improving the processing accuracy.

[0004] However, the current punching and tapping device has the following problems: When the traditional punching and tapping device clamps a circular metal, the clamping assembly clamps and fixes it from the outer ring of the circular metal. Clamping and fixing from the outer ring of the circular metal will cause uneven stress on the circular metal part, resulting in local deformation or damage, affecting the processing quality of the thread. Therefore, we propose a punching and tapping device for the manufacture of mechanical and electrical equipment. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a punching and tapping device for the manufacture of mechanical and electrical equipment, which solves the problems raised in the above background art.

[0006] To achieve the above object, the present invention is realized through the following technical solutions: A drilling and tapping device for the manufacture of mechanical and electrical equipment, including a workbench, a placement plate is fixedly connected to the top of the workbench, a drilling groove is opened on the top of the placement plate, an L-shaped plate is fixedly connected to the top of the workbench, an electric push rod is fixedly connected to the top of the L-shaped plate, a telescopic end of the electric push rod is fixedly connected to a support frame, a motor one is fixedly connected to the inner wall of the support frame, an output shaft of the motor one is fixedly connected to a tap head, a limiting device is arranged on the inner wall top of the workbench, the limiting device includes a U-shaped frame, the top of the U-shaped frame is fixedly connected to the inner wall top of the workbench, a motor two is fixedly connected to the bottom of the inner wall of the U-shaped frame, an output shaft of the motor two is fixedly connected to a turntable, a U-shaped hollow frame is fixedly connected to the top of the turntable, a bolt is threadedly connected to the inner wall of the hollow circle of the U-shaped hollow frame, a rotating block is fixedly connected to the bottom of the bolt, a moving block is rotatably connected to the bottom of the rotating block, a side surface of the moving block is slidably connected to the lower part of the inner wall of the U-shaped hollow frame, two hinge rods are hinged to the bottom of the moving block, one ends of the two hinge rods far away from the moving block are respectively hinged to a slider, bottoms of the two sliders are slidably connected to the inner wall of the turntable, a Z-shaped rod is fixedly connected to the top of the slider, a long column is rotatably connected to the top of the Z-shaped rod, a plurality of long grooves are opened on an outer wall of the long column, a plurality of small ball soft blocks are fixedly connected to inner walls of the plurality of long grooves. Place the annular metal workpiece to be processed on the placement plate, and then start the electric push rod and the motor one through an external controller. The drive of the motor one will cause the tap head to rotate. At the same time, the electric push rod will push the support frame downward. The downward movement of the support frame drives the motor one to move downward. The downward movement of the motor one drives the tap head to move downward. When the tap head rotates, it moves downward at the same time to tap the annular metal workpiece to be processed. When placing the annular metal workpiece on the placement plate, the staff rotates the bolt. The rotation of the bolt will cause it to move downward along the inner wall of the U-shaped hollow frame. The downward movement of the bolt will push the moving block downward through the rotating block. The downward movement of the moving block will push the two sliders to move away from the U-shaped hollow frame through the two hinge rods. The movement of the two sliders drives the movement of the Z-shaped rod. The movement of the Z-shaped rod drives the long column to move. At the same time, start the motor two through an external controller. The output shaft of the motor two will drive the turntable to rotate. The rotation of the turntable will drive the slider to rotate. The rotation of the slider drives the Z-shaped rod to rotate. The rotation of the Z-shaped rod drives the long column to rotate. The rotation of the long column drives the annular metal workpiece to rotate.

[0007] According to the above technical solution, a one-way bearing is fixedly connected to the top of the long column, a runner is fixedly connected to the top of the one-way bearing, an L-shaped fixing plate is fixedly connected to the side surface of the U-shaped hollow frame, a folding bellows is slidably connected to the side surface of the L-shaped fixing plate, the side surface of the folding bellows is rotatably connected to the outer wall of the one-way bearing, and the bottom of the folding bellows is provided with an inclined surface. When the long column moves, the long column will drive the one-way bearing to move, and the movement of the one-way bearing will drive the runner to move. Since friction is generated between the runner and the L-shaped fixing plate, the runner will rotate. The rotation of the runner drives the one-way bearing to rotate, and the rotation of the one-way bearing drives the long column to rotate. When the bolt is screwed in the reverse direction, the bolt will move upward. Therefore, the bolt will drive the rotating block and the moving block to move upward. The upward movement of the moving block will cause the slider to move towards the U-shaped hollow frame through the hinge rod. The movement of the slider will cause the long column to no longer contact the inner ring of the annular metal workpiece through the Z-shaped rod. At the same time, the movement of the long column will drive the one-way bearing and the runner to move. Due to the limitation of the one-way bearing, when the long column no longer contacts the inner ring of the annular metal workpiece, the runner will not drive the long column to rotate.

[0008] According to the above technical solution, the outer wall of the runner is provided with a rough surface, the side surface of the L-shaped fixing plate is provided with a rough surface, and the rough surface of the runner is in contact with the rough surface of the L-shaped fixing plate.

[0009] According to the above technical solution, a marking device is arranged on the top of the workbench. The marking device includes a support block, the bottom of the support block is fixedly connected to the top of the workbench, a liquid storage tank is fixedly connected to the top of the support block, a pressing member is fixedly connected to the top of the liquid storage tank, an elastic telescopic rod is fixedly connected to the side surface of the liquid storage tank, a pushing block is fixedly connected to the telescopic end of the elastic telescopic rod, a nozzle is fixedly connected to the bottom of the pushing block, a folding tube is fixedly connected to the outer wall of the nozzle, and one end of the folding tube far away from the nozzle is fixedly connected to the side surface of the liquid storage tank. A contact plate is fixedly connected to the bottom of the support frame. When preparing to place the annular metal workpiece, the worker manually squeezes the elastic telescopic rod by pushing the pushing block. Therefore, the movement of the pushing block causes the nozzle to fold the folding tube. When the annular metal workpiece is placed, the elastic telescopic rod will drive the pushing block, the nozzle and the folding tube to reset through its own elastic force. Every time the support frame moves downward, it will drive the contact plate to move downward. The downward movement of the contact plate will press the pressing member, so that the marking liquid on the inner wall of the liquid storage tank is sprayed from the nozzle to the surface of the annular metal workpiece through the folding tube.

[0010] According to the above technical solution, a short plate is fixedly connected to the outer wall of the nozzle, and a cross-shaped hollow block is fixedly connected to the side surface of the short plate. The cross-shaped hollow block is located below the nozzle.

[0011] According to the above technical solution, the pressing piece is used to control the marking liquid inside the liquid storage tank to be sprayed out from the nozzle through the folding tube, and a pressing block is fixedly connected to the bottom of the contact plate. The pressing end of the pressing piece is located on the displacement trajectory of the pressing block. At the same time, when the marking liquid is sprayed from the nozzle to the surface of the annular metal workpiece through the folding tube, the cross hollow block will limit the marking liquid sprayed from the nozzle to the surface of the annular metal workpiece.

[0012] According to the above technical solution, a top flushing device is provided at the bottom of the U-shaped frame, and the top flushing device includes a water tank, the top of the water tank is fixedly connected to the bottom of the U-shaped frame, the side of the water tank is fixedly connected to a water pump, the side of the water pump is fixedly connected to a long tube, the outer wall of the long tube is fixedly connected to an L-shaped bracket, the bottom of the L-shaped bracket is fixedly connected to the top of the water tank, the end of the long tube away from the water pump is rotatably connected to a rotating tube, the top of the rotating tube is fixedly connected to multiple nozzles, the multiple nozzles are located below the drilling groove, and the water pump is driven by an external controller. The water pump will cause the tapping fluid inside the water tank to be sprayed out from the multiple nozzles through the long tube and the rotating tube. After each tapping of the tap head is completed, the tapping fluid sprayed from the multiple nozzles will be sprayed upward along the bottom of the drilling groove, which can directly flush and push the chips to the outside, thereby avoiding the accumulation of chips in the drilling groove.

[0013] According to the above technical solution, a large ring is fixedly connected to the outer wall of the turntable, a small ring is fixedly connected to the outer wall of the rotating tube, the outer wall of the large ring is set as a rough surface, the side surface of the small ring is set as a rough surface, the rough surface of the large ring is in contact with the rough surface of the small ring, and the rotation of the turntable drives the large ring to rotate. Under the friction force between the large ring and the small ring, the small ring will rotate, and the rotation of the small ring will drive the rotating tube to rotate, and the rotation of the rotating tube drives the multiple nozzles to rotate.

[0014] The present invention provides a drilling and tapping device for mechanical and electrical equipment manufacturing.

[0015] Beneficial effects:

[0016] (1) The present invention uses the coordination of bolts, rotating blocks, moving blocks, hinged rods, sliders, Z-shaped rods, and long columns to enable the movement of the Z-shaped rod to drive the long column to move. The movement of the long column can fix the annular metal workpiece through the inner ring of the annular metal workpiece, thereby avoiding the problem of excessive clamping of the outer ring in the traditional way, which causes deformation or damage to the annular metal workpiece. At the same time, through the coordination of the long column and the small ball soft block, the long column can make the small ball soft block on the surface of the long column contact the inner ring of the annular metal workpiece. As a soft material, the small ball soft block can evenly distribute the contact force, reduce local stress concentration, and avoid deformation and damage that may be caused by a single contact point. In this way, the risk of deformation of the inner ring can be effectively reduced, ensuring that the clamping force is more evenly distributed. At the same time, through the coordination of the long column, the one-way bearing, the rotating wheel, the L-shaped fixing plate, and the folding drum, the rotating wheel will not drive The long column rotates to ensure that the surface of the long column is different each time it hits the inner circle of the annular metal workpiece, avoiding the problem of long-term repeated force on the local contact surface of the long column, which leads to a decrease in the clamping force of the long column. At the same time, the bottom of the folding drum will first hit the top of the annular metal workpiece, so that the annular metal workpiece squeezes the folding drum. When the folding drum stops moving, the folding drum will press the inner wall edge of the annular metal workpiece through its own internal pressure, thereby improving the stability of the annular metal workpiece during tapping. At the same time, through the cooperation of motor 2, turntable, slider, Z-shaped rod and long column, the rotation of the Z-shaped rod will drive the long column to rotate, and the rotation of the long column will drive the annular metal workpiece to rotate, so as to tap another place of the annular metal workpiece, reducing the workload of the staff to manually rotate the annular metal workpiece.

[0017] (2) The present invention cooperates with a liquid storage tank, a pressing part, an elastic telescopic rod, a push block, a nozzle, a folding tube, and a resistance plate, so that the marking liquid on the inner wall of the liquid storage tank is sprayed from the nozzle to the surface of the annular metal workpiece through the folding tube, thereby marking the place where the circular metal workpiece is about to be tapped, ensuring that the spacing of each tapping is the same, and after the circular metal workpiece is processed, the staff can see whether there is a mark on the surface of the circular metal workpiece. If there is a mark, it means that the tapping of the circular metal workpiece is not compliant; at the same time, through the cooperation of the nozzle and the cross hollow block, the cross hollow block will limit the marking liquid sprayed by the nozzle onto the surface of the annular metal workpiece, thereby avoiding the problem of excessive scattering of the marking liquid, which may lead to misjudgment by the staff.

[0018] (3) Through the cooperation of the water storage tank, long pipe, water pump, rotating pipe, and multiple nozzles, the tapping fluid ejected from the multiple nozzles will spray upward along the bottom of the drilling groove, directly flushing and pushing the chips to the outside, thus avoiding the accumulation of chips in the drilling groove, reducing the risk of drilling groove blockage and tool jamming, and improving the processing efficiency; at the same time, through the cooperation of the large ring, small ring, and multiple nozzles, the rotation of the small ring drives the rotating pipe to rotate, the rotation of the rotating pipe drives the multiple nozzles to rotate, and the rotation of the multiple nozzles makes the ejected tapping fluid spiral, and the spiral tapping fluid can further improve the chip discharge effect.

Detailed Embodiment

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0028] Please refer to Figures 1 - 7 , an embodiment of the present invention is: a drilling and tapping device for the manufacture of mechanical and electrical equipment, including a workbench 1. A placement plate 2 is fixedly connected to the top of the workbench 1. A drilling groove 21 is opened on the top of the placement plate 2. An L-shaped plate 3 is fixedly connected to the top of the workbench 1. An electric push rod 4 is fixedly connected to the top of the L-shaped plate 3. The electric push rod 4 is electrically connected to an external controller. The telescopic end of the electric push rod 4 is fixedly connected to a support frame 5. A first motor 6 is fixedly connected to the inner wall of the support frame 5. The first motor 6 is electrically connected to an external controller. The output shaft of the first motor 6 is fixedly connected to a tap head 10. A limiting device 7 is arranged on the inner wall top of the workbench 1. The limiting device 7 includes a U-shaped frame 71. The top of the U-shaped frame 71 is fixedly connected to the inner wall top of the workbench 1. A second motor 72 is fixedly connected to the inner wall bottom of the U-shaped frame 71. The second motor 72 is electrically connected to an external controller. The output shaft of the second motor 72 is fixedly connected to a turntable 73. A U-shaped hollow frame 74 is fixedly connected to the top of the turntable 73. A bolt 75 is threadedly connected to the inner wall of the hollow circle of the U-shaped hollow frame 74. The bottom of the bolt 75 is fixedly connected to a rotating block 76. The bottom of the rotating block 76 is rotatably connected to a moving block 77. The side of the moving block 77 is slidably connected to the lower part of the inner wall of the U-shaped hollow frame 74. The bottom of the moving block 77 is hinged with two hinge rods 78. One end of each of the two hinge rods 78 away from the moving block 77 is hinged with a slider 79. The bottoms of the two sliders 79 are both slidably connected to the inner wall of the turntable 73. The top of the slider 79 is fixedly connected to a Z-shaped rod 710. The top of the Z-shaped rod 710 is rotatably connected to a long column 711. A plurality of long grooves are opened on the outer wall of the long column 711. A plurality of small ball soft blocks 712 are fixedly connected to the inner walls of the plurality of long grooves. Through the setting of the above structure, the movement of the long column 711 will fix the annular metal workpiece through the inner ring of the annular metal workpiece, thus avoiding the problem that the traditional outer ring clamping is too strong, resulting in deformation or damage of the annular metal workpiece. At the same time, the long column 711 will make the small ball soft blocks 712 on the surface also contact the inner ring of the annular metal workpiece. As a soft material, the small ball soft blocks 712 can evenly distribute the contact force, reduce local stress concentration, and avoid deformation and damage that may be caused by a single contact point. In this way, the risk of deformation of the inner ring can be effectively reduced, ensuring that the clamping force is more evenly distributed. And the rotation of the Z-shaped rod 710 will drive the long column 711 to rotate, and the rotation of the long column 711 will drive the annular metal workpiece to rotate, so as to tap another place of the annular metal workpiece, reducing the workload of the staff manually rotating the annular metal workpiece.

[0029] A one-way bearing 713 is fixedly connected to the top of the long column 711. A runner 714 is fixedly connected to the top of the one-way bearing 713. An L-shaped fixing plate 715 is fixedly connected to the side surface of the U-shaped hollow frame 74. A folding bellows 716 is slidably connected to the side surface of the L-shaped fixing plate 715. The side surface of the folding bellows 716 is rotatably connected to the outer wall of the one-way bearing 713. The bottom of the folding bellows 716 is provided with an inclined surface. The outer wall of the runner 714 is provided with a rough surface. The side surface of the L-shaped fixing plate 715 is provided with a rough surface. The rough surface of the runner 714 is in contact with the rough surface of the L-shaped fixing plate 715. Through the setting of the above structure, the runner 714 will not drive the long column 711 to rotate, so as to ensure that the surface of the long column 711 in contact with the inner ring of the annular metal workpiece is different each time, avoiding the problem that the local contact surface of the long column 711 is repeatedly stressed for a long time, resulting in the reduction of the clamping force of the long column 711.

[0030] A marking device 8 is arranged on the top of the workbench 1. The marking device 8 includes a support block 81. The bottom of the support block 81 is fixedly connected to the top of the workbench 1. A liquid storage tank 82 is fixedly connected to the top of the support block 81. A pressing member 83 is fixedly connected to the top of the liquid storage tank 82. The working principle of the pressing member 83 here is similar to that of a spray bottle. The pressing member 83 is composed of a pressing part and a spring pump, so as to realize reset through the elastic force of the spring pump. An elastic telescopic rod 84 is fixedly connected to the side surface of the liquid storage tank 82. The telescopic end of the elastic telescopic rod 84 is fixedly connected to a push block 85. A spray head 86 is fixedly connected to the bottom of the push block 85. A folding pipe 87 is fixedly connected to the outer wall of the spray head 86. One end of the folding pipe 87 far away from the spray head 86 is fixedly connected to the side surface of the liquid storage tank 82. A contact plate 88 is fixedly connected to the bottom of the support frame 5. The pressing member 83 is used to control the marking liquid inside the liquid storage tank 82 to be sprayed out from the spray head 86 through the folding pipe 87. A pressing block is fixedly connected to the bottom of the contact plate 88. The pressing end of the pressing member 83 is located on the displacement track of the pressing block. Through the setting of the above structure, the marking liquid on the inner wall of the liquid storage tank 82 is sprayed from the spray head 86 to the surface of the annular metal workpiece through the folding pipe 87, so as to mark the place where the circular metal part is about to be tapped, ensure that the tapping spacing is the same each time, and after the circular metal part is processed, the staff can see whether there is a mark on the surface of the circular metal part. If there is a mark, it means that the tapping of the circular metal part is not compliant.

[0031] A short board 89 is fixedly connected to the outer wall of the spray head 86. A cross-shaped hollow block 810 is fixedly connected to the side surface of the short board 89. The cross-shaped hollow block 810 is located below the spray head 86. Through the setting of the above structure, the cross-shaped hollow block 810 will limit the marking liquid sprayed from the spray head 86 to the surface of the annular metal workpiece, so as to avoid the problem that the scattering range of the marking liquid is too large, resulting in misjudgment by the staff.

[0032] During use, place the annular metal workpiece to be processed on the placement plate 2, and then start the electric push rod 4 and the first motor 6 through an external controller. The drive of the first motor 6 will cause the tap head 10 to rotate. At the same time, the electric push rod 4 will push the support frame 5 downward. The downward movement of the support frame 5 drives the first motor 6 downward, and the downward movement of the first motor 6 drives the tap head 10 downward. The tap head 10 moves downward while rotating to tap the annular metal workpiece to be processed. When placing the annular metal workpiece on the placement plate 2, the worker rotates the bolt 75. When the bolt 75 rotates, it will move downward along the inner wall of the U-shaped hollow frame 74. The downward movement of the bolt 75 will push the moving block 77 downward through the rotating block 76. The downward movement of the moving block 77 will push the two sliders 79 to move away from the U-shaped hollow frame 74 through the two hinge rods 78. The movement of the two sliders 79 drives the movement of the Z-shaped rod 710. The movement of the Z-shaped rod 710 drives the movement of the long column 711. The movement of the long column 711 will fix the annular metal workpiece through the inner ring of the annular metal workpiece, thus avoiding the problem that the traditional outer ring clamping is too strong, resulting in deformation or damage of the annular metal workpiece; when the long column 711 touches the inner ring of the annular metal workpiece, the small ball soft block 712 on the surface of the long column 711 will also touch the inner ring of the annular metal workpiece. As a soft material, the small ball soft block 712 can evenly distribute the contact force, reduce local stress concentration, and avoid deformation and damage that may be caused by a single contact point. In this way, the risk of deformation of the inner ring can be effectively reduced, and it is ensured that the clamping force is more evenly distributed; when the long column 711 moves, the long column 711 will drive the one-way bearing 713 to move. The movement of the one-way bearing 713 will drive the runner 714 to move. Since there is friction between the runner 714 and the L-shaped fixing plate 715, the runner 714 will rotate. The rotation of the runner 714 drives the one-way bearing 713 to rotate. The rotation of the one-way bearing 713 drives the long column 711 to rotate. When the bolt 75 is screwed in the reverse direction, the bolt 75 will move upward. Therefore, the bolt 75 will drive the rotating block 76 and the moving block 77 upward. The upward movement of the moving block 77 will cause the slider 79 to move toward the U-shaped hollow frame 74 through the hinge rod 78. The movement of the slider 79 will cause the long column 711 to no longer touch the inner ring of the annular metal workpiece through the Z-shaped rod 710. At the same time, the movement of the long column 711 will drive the one-way bearing 713 and the runner 714 to move. Due to the limitation of the one-way bearing 713, when the long column 711 no longer touches the inner ring of the annular metal workpiece, the runner 714 will not drive the long column 711 to rotate, thus ensuring that the surface when the long column 711 touches the inner ring of the annular metal workpiece each time is different, and avoiding the problem that the clamping force of the long column 711 is reduced due to the local contact surface of the long column 711 being repeatedly stressed for a long time;When the one-way bearing 713 moves, the one-way bearing 713 will push the folding bellows 716 towards the top of the annular metal workpiece. The bottom of the folding bellows 716 will first contact the top of the annular metal workpiece, causing the annular metal workpiece to squeeze the folding bellows 716. When the folding bellows 716 stops moving, the folding bellows 716 will press against the inner wall edge of the annular metal workpiece through the pressure inside itself, thereby improving the stability of the annular metal workpiece during the tapping process. When tapping is completed in one direction of the annular metal workpiece, the motor two 72 is started through an external controller. The output shaft of the motor two 72 will drive the turntable 73 to rotate. The rotation of the turntable 73 will drive the slider 79 to rotate. The rotation of the slider 79 drives the Z-shaped rod 710 to rotate. The rotation of the Z-shaped rod 710 will drive the long column 711 to rotate. The rotation of the long column 711 drives the annular metal workpiece to rotate, thereby tapping another place on the annular metal workpiece and reducing the workload of the staff manually rotating the annular metal workpiece.;

[0033] When preparing to place the annular metal workpiece, the staff manually squeezes the elastic telescopic rod 84 by pushing the push block 85. Therefore, the movement of the push block 85 causes the nozzle 86 to fold the folding tube 87. When the annular metal workpiece is placed, the elastic telescopic rod 84 will drive the push block 85, the nozzle 86, and the folding tube 87 to reset through its own elastic force. Every time the support frame 5 moves downward, it will drive the contact plate 88 to move downward. The downward movement of the contact plate 88 will press the pressing member 83, causing the marking liquid on the inner wall of the liquid storage tank 82 to be sprayed from the nozzle 86 through the folding tube 87 onto the surface of the annular metal workpiece, thereby marking the place on the circular metal part that is about to be tapped, ensuring that the tapping spacing is the same each time. And after the circular metal part is processed, the staff can see whether there is a mark on the surface of the circular metal part. If there is a mark, it means that the tapping of the circular metal part is non-compliant. At the same time, when the marking liquid is sprayed from the nozzle 86 through the folding tube 87 onto the surface of the annular metal workpiece, the cross-shaped hollow block 810 will limit the marking liquid sprayed from the nozzle 86 onto the surface of the annular metal workpiece, thereby avoiding the problem that the scattering range of the marking liquid is too large, resulting in misjudgment by the staff.

The bottom of the L-shaped bracket 96 is fixedly connected to the top of the water storage tank 91. One end of the long pipe 92 away from the water pump 93 is rotatably connected to a rotating pipe 94. A multi-nozzle 95 is fixedly connected to the top of the rotating pipe 94. The multi-nozzle 95 is located below the drilling groove 21. Through the setting of the above structure, the tapping fluid ejected from the multi-nozzle 95 will spray upward along the bottom of the drilling groove 21, and can directly wash and push the chips to the outside, thereby avoiding the accumulation of chips in the drilling groove 21, reducing the risk of blockage of the drilling groove 21 and jamming of the tool, and improving the processing efficiency.

[0035] A large ring 97 is fixedly connected to the outer wall of the turntable 73. A small ring 98 is fixedly connected to the outer wall of the rotating pipe 94. The outer wall of the large ring 97 is set as a rough surface, and the side surface of the small ring 98 is set as a rough surface. The rough surface of the large ring 97 is in contact with the rough surface of the small ring 98. Through the setting of the above structure, the rotation of the rotating pipe 94 drives the multi-nozzle 95 to rotate. The rotation of the multi-nozzle 95 will make the ejected tapping fluid spiral. The spiral tapping fluid can further improve the chip discharge effect.

[0036] During use, the water pump 93 is driven by an external controller. The water pump 93 will cause the tapping fluid inside the water storage tank 91 to be ejected from the multi-nozzle 95 through the long pipe 92 and the rotating pipe 94. After each tapping of the tap head 10 is completed, the tapping fluid ejected from the multi-nozzle 95 will spray upward along the bottom of the drilling groove 21, and can directly wash and push the chips to the outside, thereby avoiding the accumulation of chips in the drilling groove 21, reducing the risk of blockage of the drilling groove 21 and jamming of the tool, and improving the processing efficiency; at the same time, the rotation of the turntable 73 drives the large ring 97 to rotate. Under the friction force of the large ring 97 and the small ring 98, the small ring 98 will rotate. The rotation of the small ring 98 will drive the rotating pipe 94 to rotate. The rotation of the rotating pipe 94 drives the multi-nozzle 95 to rotate. The rotation of the multi-nozzle 95 will make the ejected tapping fluid spiral. The spiral tapping fluid can further improve the chip discharge effect.
