[0035] The present invention also discloses a method for using a drilling and tapping dual-purpose mechanism for producing fireproof doors and windows, which specifically comprises the following steps:

[0036] Step 1. After placing the drill bit, a waste chip cleaning head, a tap and another waste chip cleaning head in the drill bit placement step hole, the first cleaning step hole, the tap placement step hole and the second cleaning step hole respectively, control the first electric telescopic rod to retract, and the first electric telescopic rod drives the vertical rod to rise. During the process, the guide rod slides along a slide groove until it contacts the top surface of the special-shaped guide plate, and then enters the inclined guide groove, and then the guide rod enters the adjacent slide groove. During the process, the vertical rod drives the integrated block to rotate ninety degrees, and then controls the first electric telescopic rod to extend, and the first electric telescopic rod drives the vertical rod to descend, and the guide rod slides along the slide groove. After the groove slides to contact the bottom surface of the special-shaped guide plate, as the vertical rod continues to descend, the guide rod pushes the special-shaped guide plate to rotate. After the guide rod is separated from the special-shaped guide plate, the special-shaped guide plate is reset to the top of the limit plate, and the extension and retraction of the first electric telescopic rod is controlled to complete the assembly of the drill bit, a waste chip cleaning head, a tap and another waste chip cleaning head. Then, the first electric telescopic rod is controlled to retract so that the guide rod is in the inclined guide groove to complete the assembly. The threaded hole to be opened of the door and window component is placed directly below the through hole, and the first electric telescopic rod is retracted. The vertical rod drives the integrated block to rotate, so that the drill bit moves to the top of the through hole.

[0037] Step 2: During the process of the drill bit moving to the top of the through hole, the integrated block drives the ring to rotate, the ring drives the first trigger convex plate to squeeze the extrusion rod, the extrusion rod squeezes the third spring, and drives the trigger sleeve to contact the first electric control switch. At this time, the second electric telescopic rod contracts the set first distance, that is, the second electric telescopic rod drives the top plate to lower the two assembly plates, the assembly plate drives the small gear to lower the positioning tube, the positioning tube drives the rubber joint sleeve to lower the spline column, after the spline column is inserted into the spline groove, as the spline column continues to descend, the first spring is compressed, the rear assembly plate drives the first trigger button to contact and squeeze the trigger rod, after the first trigger button is compressed, the drive motor is started, the drive motor drives the large gear to rotate, the large gear drives the small gear to accelerate the rotation of the positioning tube, the positioning tube drives the rubber joint sleeve to rotate the spline column, and the spline column drives the drive disk to rotate the drill bit;

[0038] Step 3, control the first electric telescopic rod to extend, the first electric telescopic rod pushes the vertical rod to descend along the guide rod, the vertical rod pushes the integrated block to descend, the integrated block drives the collar to push the clamping plate to descend the bottom plate, the bottom plate pulls the second electric telescopic rod to descend the top plate along the connecting rod, at this time, the spline column squeezes the driving disk to make the drill pass through the through hole, and drills the door and window components, after the drilling is completed, control the first electric telescopic rod to retract, so that the drill is separated from the through hole, control the second electric telescopic rod to extend and reset, so that the spline column is separated from the drill to place the stepped hole, during the process, the first trigger button is separated from the trigger rod, and the drive motor is turned off;

[0039] Step 4: After the first electric telescopic rod is retracted and reset in step 3 until the guide rod moves out of the inclined guide groove, the integrated block rotates 90 degrees. At this time, a waste cleaning head is directly above the through hole, and the integrated block drives the collar to rotate, so that the second trigger convex plate squeezes the squeezing rod, and the squeezing rod squeezes the third spring and drives the trigger sleeve to contact the second electric control switch. At this time, the second electric telescopic rod shrinks the set second distance, that is, the second electric telescopic rod shrinks, so that the spline column descends into the first cleaning stepped hole, and the second trigger button is squeezed. In the process, the first electric telescopic rod is extended, and the stepped insert tube of the waste cleaning head is moved to the drilling hole of the door and window component in step three, and then the air pump is started. The air pump accelerates the air to enter the air inlet cavity through the double air chamber box, and after the waste chips at the drilling hole are blown up, the waste chips enter the double air chamber box through the air outlet cavity, and then enter the filter cover through the air outlet and the air inlet in turn. The waste chips are collected in the filter cover. After the set cleaning time, the first electric telescopic rod is controlled to retract, so that the stepped insert tube is separated from the through hole, and the second electric telescopic rod is controlled to extend and reset, so that the spline column is separated from the first cleaning stepped hole;

[0040] Step 5. After the first electric telescopic rod is retracted and reset in step 4 until the guide rod moves out of the inclined guide groove, the integrated block rotates 90 degrees. At this time, the tap is directly above the through hole. Repeat steps 2 and 3 to perform internal thread processing on the drilled holes of the door and window components. Then repeat step 4 to clean up the waste chips of the door and window components that have completed the internal thread processing, and complete the threaded hole processing of the door and window components.

[0041] The present invention is further configured as follows: when the second electric telescopic rod drives the top plate to lower the two assembly plates, the top plate drives the special-shaped extrusion plate to lower. During the process, the inclined surface of the special-shaped extrusion plate is pressed against the rotating shaft, the rotating shaft drives the block to press the sliding rod, and the sliding rod drives the semicircular plug block to be inserted into the slot to limit the driving disk or the top of the stepped insert pipe. During the process, the semicircular plug block stretches the fourth spring. During the extension and reset process of the second electric telescopic rod, after the inclined surface is separated from the rotating shaft, the fourth spring is reset and the semicircular plug block is separated from the slot.

[0042] The present invention provides a drilling and tapping dual-purpose mechanism for producing fireproof doors and windows and a method for using the same. It has the following beneficial effects:

[0043] (1) The present invention cooperates with a drill bit, a waste chip cleaning head, a tap and another waste chip cleaning head with an integrated block. After the lifting and rotating assembly completes a lifting stroke, the drill bit, a waste chip cleaning head, a tap and another waste chip cleaning head can work alternately. In combination with the arrangement of the pressing and rotating assembly and the processing table, the effects of waste chip cleaning after drilling and after tapping are achieved, thereby ensuring good tapping accuracy of fireproof door and window components.

[0044] (2) The present invention provides support for the compression rotating assembly to drive the drill bit and the tap to rotate by means of the arrangement of the compression rotating assembly, the first trigger button and the two trigger rods. Furthermore, under the arrangement of the rubber joint tube, the push rod and the first spring, the spline column and the spline groove are stably plugged in and matched, thereby providing stable protection for the rotation drive of the drill bit and the tap.

[0045] (3) The present invention provides guiding conditions for controlling the retraction distance of the second electric telescopic rod through the arrangement of the collar, two first trigger convex plates, two second trigger convex plates, the control tube, the third spring, the extrusion rod, the trigger sleeve, the first electric control switch and the second electric control switch, and provides stable guarantees for the cooperation between the spline column and the spline groove, and the cooperation between the spline column and the second trigger button, thereby ensuring the long-term stable operation of the device.

[0046] (4) The present invention can utilize the semicircular insert block to limit the top position of the drive disk and the stepped insert pipe by coordinating the special-shaped extrusion plate, the fixed plate, the slide rod, the block, the rotating shaft, the semicircular insert block and the slot, so as to ensure the stability during the drilling and chip cleaning process of the fireproof door and window components.

[0047] (5) The present invention divides the step tube into an air inlet cavity and an air outlet cavity by means of an isolation plate, and cooperates with the arrangement of a double air chamber box, an air pump and an air outlet. After the step tube falls on the fireproof door and window component, air can be blown on one side and discharged on the other side, thereby achieving effective cleaning of waste chips during the drilling and tapping process, ensuring the accuracy of non-through-hole tapping processing on the fireproof doors and windows, and cooperating with the arrangement of blind holes to ensure the cleaning of waste chips during through-hole tapping processing on the fireproof doors and windows, thereby improving the scope of application of the device.

[0048] (6) The present invention can collect the discharged waste chips in the filter cover through the coordination of the air hole and the air outlet hole. The setting of the movable groove and the card slot can ensure the vertical up and down movement when the stepped tube is limited by the support plate. With the setting of the sealing plate and the fifth spring, after the double air chamber box is separated from the sealing plate, the sealing plate can be used to block the air hole. When the double air chamber box is squeezed by the spline column, the sealing plate can be squeezed to achieve the connection between the air outlet and the air hole, providing reliable guarantee for the effective collection of waste chips.

[0084] A method for using a drilling and tapping dual-purpose mechanism for producing fireproof doors and windows, specifically comprising the following steps:

[0085] Step 1. After placing the drill bit 2, a waste chip cleaning head 10, the tap 3 and another waste chip cleaning head 10 in the drill bit placement step hole 6, the first cleaning step hole 7, the tap placement step hole 8 and the second cleaning step hole 9 respectively, control the first electric telescopic rod 16 to retract, and the first electric telescopic rod 16 drives the vertical rod 17 to rise. During the process, the guide rod 21 slides along a slide groove 18 until it contacts the top surface of the special-shaped guide plate 22, and then enters the inclined guide groove 19. After that, the guide rod 21 enters the adjacent slide groove 18. During the process, the vertical rod 17 drives the integrated block 5 to rotate ninety degrees, and then controls the first electric telescopic rod 16 to extend, and the first electric telescopic rod 16 drives the vertical rod 17 to descend, and the guide rod 21 slides along the slide groove After 18 slides to contact the bottom surface of the special-shaped guide plate 22, as the vertical rod 17 continues to descend, the guide rod 21 pushes the special-shaped guide plate 22 to rotate. After the guide rod 21 is separated from the special-shaped guide plate 22, the special-shaped guide plate 22 is reset to the top of the limit plate 23, and the extension and contraction of the first electric telescopic rod 16 can be controlled to complete the assembly of the drill bit 2, a waste chip cleaning head 10, the tap 3 and another waste chip cleaning head 10. Then, the first electric telescopic rod 16 is controlled to retract so that the guide rod 21 is in the inclined guide groove 19 to complete the assembly, and the threaded hole to be opened of the door and window component is disposed directly below the through hole 29. The first electric telescopic rod 16 is retracted, and the vertical rod 17 drives the integrated block 5 to rotate, so that the drill bit 2 moves to the top of the through hole 29.

[0086] Step 2: During the process of the drill bit 2 moving to the top of the through hole 29, the integrated block 5 drives the collar 46 to rotate, the collar 46 drives the first trigger convex plate 54 to squeeze the squeezing rod 49, the squeezing rod 49 squeezes the third spring 50, and drives the trigger sleeve 51 to contact the first electric control switch 52. At this time, the second electric telescopic rod 33 contracts the set first distance, that is, the second electric telescopic rod 33 drives the top plate 31 to make the two assembly plates 34 descend, the assembly plate 34 drives the pinion 37 to make the positioning tube 38 descend, and the positioning tube 38 drives the rubber joint sleeve 39 to make the flower The key column 40 descends. After the spline column 40 is inserted into the spline groove 41, as the spline column 40 continues to descend, the first spring 43 is compressed, and the rear assembly plate 34 drives the first trigger button 44 to contact and squeeze the trigger rod 45. After the first trigger button 44 is compressed, the drive motor 35 is started, and the drive motor 35 drives the large gear 36 to rotate. The large gear 36 drives the small gear 37 to accelerate the rotation of the positioning tube 38. The positioning tube 38 drives the rubber joint sleeve 39 to rotate the spline column 40, and the spline column 40 drives the drive disk 12 to rotate the drill bit 2.

[0087] Step 3, control the first electric telescopic rod 16 to extend, the first electric telescopic rod 16 pushes the vertical rod 17 to descend along the guide rod 21, the vertical rod 17 pushes the integrated block 5 to descend, the integrated block 5 drives the collar 46 to push the clamping plate 47 to descend the bottom plate 32, the bottom plate 32 pulls the second electric telescopic rod 33 to descend the top plate 31 along the connecting rod 28, at this time, the spline column 40 squeezes the driving disk 12 to make the drill bit 2 pass through the through hole 29, and drills the door and window components, after the drilling is completed, control the first electric telescopic rod 16 to retract, so that the drill bit 2 is separated from the through hole 29, control the second electric telescopic rod 33 to extend and reset, so that the spline column 40 is separated from the drill bit to place the stepped hole 6, during the process, the first trigger button 44 is separated from the trigger rod 45, and the drive motor 35 is turned off;

[0088] Step 4: After the first electric telescopic rod 16 is retracted and reset in step 3 until the guide rod 21 moves out of the inclined guide groove 19, the integrated block 5 rotates ninety degrees. At this time, a waste cleaning head 10 is directly above the through hole 29, and the integrated block 5 drives the collar 46 to rotate, so that the second trigger convex plate 55 squeezes the squeezing rod 49, and the squeezing rod 49 squeezes the third spring 50, and drives the trigger sleeve 51 to contact the second electric control switch 53. At this time, the second electric telescopic rod 33 shrinks the set second distance, that is, the second electric telescopic rod 33 shrinks, so that the spline column 40 descends into the first cleaning stepped hole 7, and squeezes the second trigger button 80. , the first electric telescopic rod 16 is extended, so that the stepped insert 66 of the waste cleaning head 10 moves to the drilling hole of the door and window component in step three, and then the air pump 71 is started. The air pump 71 accelerates the air to pass through the double air chamber box 70 into the air inlet cavity 68, and after blowing up the waste at the drilling hole, the waste passes through the air outlet cavity 69 into the double air chamber box 70, and then passes through the air outlet 72 and the air outlet 76 into the filter cover 74 in turn, and the waste is collected in the filter cover 74. After the cleaning time is set, the first electric telescopic rod 16 is controlled to retract, so that the stepped insert 66 is separated from the through hole 29, and the second electric telescopic rod 33 is controlled to extend and reset, so that the spline column 40 is separated from the first cleaning stepped hole 7;

[0089] Step 5. After the first electric telescopic rod 16 is retracted and reset in step 4 until the guide rod 21 moves to disengage the inclined guide groove 19, the integrated block 5 rotates ninety degrees. At this time, the tap 3 is directly above the through hole 29. During the process, the integrated block 5 drives the ring 46 to rotate, and the ring 46 drives the first trigger convex plate 54 to squeeze the extrusion rod 49. The extrusion rod 49 squeezes the third spring 50 and drives the trigger sleeve 51 to contact the first electric control switch 52. At this time, the second electric telescopic rod 33 contracts the set first distance, that is, the second electric telescopic rod 33 drives the top plate 31 to make the two assembly plates 34 descend, the assembly plate 34 drives the pinion 37 to make the positioning tube 38 descend, and the positioning tube 38 drives the rubber joint sleeve 39 to make the spline column 40 descend. After the spline column 40 is inserted into the spline groove 41, as the spline column 40 continues to descend, the first spring 43 is compressed, and the rear assembly plate 34 drives the first trigger button 44 to contact and squeeze the trigger rod 45. After the first trigger button 44 is compressed, the drive motor 35 is started. The machine 35 drives the large gear 36 to rotate, the large gear 36 drives the small gear 37 to accelerate the rotation of the positioning tube 38, the positioning tube 38 drives the rubber joint sleeve 39 to rotate the spline column 40, the spline column 40 drives the driving disk 12 to rotate the tap 3, and controls the first electric telescopic rod 16 to extend, the first electric telescopic rod 16 pushes the vertical rod 17 to descend along the guide rod 21, the vertical rod 17 pushes the integrated block 5 to descend, the integrated block 5 drives the collar 46 to push the clamping plate 47 to descend the bottom plate 32, and the bottom plate 32 pulls the second electric telescopic rod 16 to extend, and the first electric telescopic rod 16 pushes the vertical rod 17 to descend along the guide rod 21, and the vertical rod 17 pushes the integrated block 5 to descend, and the integrated block 5 drives the collar 46 to push the clamping plate 47 to descend the bottom plate 32. The telescopic rod 33 makes the top plate 31 descend along the connecting rod 28. At this time, the spline column 40 squeezes the driving disk 12 to make the tap 3 pass through the through hole 29 and tap the door and window component. After the tapping is completed, the first electric telescopic rod 16 is controlled to retract to make the drill bit 2 disengage from the through hole 29, and the second electric telescopic rod 33 is controlled to extend and reset to make the spline column 40 disengage from the tap and place in the stepped hole 8. During the process, the first trigger button 44 is disengaged from the trigger rod 45, and the drive motor 35 is turned off to complete the internal thread processing at the drilling hole of the door and window component.

[0090] Step 6. After the first electric telescopic rod 16 is retracted and reset in step 5 until the guide rod 21 moves out of the inclined guide groove 19, the integrated block 5 rotates ninety degrees. At this time, the other waste cleaning head 10 is directly above the through hole 29, and the integrated block 5 drives the collar 46 to rotate, so that the second trigger convex plate 55 squeezes the squeezing rod 49, and the squeezing rod 49 squeezes the third spring 50, and drives the trigger sleeve 51 to contact the second electric control switch 53. At this time, the second electric telescopic rod 33 shrinks the set second distance, that is, the second electric telescopic rod 33 shrinks, so that the spline column 40 descends into the second cleaning stepped hole 9, and the second trigger button 80 is squeezed. In the process, the first electric telescopic rod 33 is retracted to the second cleaning step hole 9, and the second trigger button 80 is squeezed. The retracting rod 16 is extended, so that the stepped insert 66 of the waste cleaning head 10 moves to the tapping position of the door and window component in step five, and then the air pump 71 is started. The air pump 71 accelerates the air to pass through the double air chamber box 70 into the air inlet cavity 68, and after blowing up the waste chips at the tapping position, the waste chips pass through the air outlet cavity 69 into the double air chamber box 70, and then pass through the air outlet 72 and the air outlet 76 into the filter cover 74 in turn, where the waste chips are collected. After the set cleaning time, the first electric telescopic rod 16 is controlled to retract, so that the stepped insert 66 is disengaged from the through hole 29, and the second electric telescopic rod 33 is controlled to extend and reset, so that the spline column 40 is disengaged from the second cleaning stepped hole 9, thereby completing the threaded hole processing of the door and window component.

[0091] As a detailed description, during the process of the second electric telescopic rod 33 driving the top plate 31 to lower the two assembly plates 34, the top plate 31 drives the special-shaped extrusion plate 61 to lower. During the process, the inclined surface 63 of the special-shaped extrusion plate 61 squeezes the rotating shaft 60, and the rotating shaft 60 drives the block 59 to squeeze the slide bar 57. The slide bar 57 drives the semicircular plug block 58 to be inserted into the slot 65 to limit the top of the drive disk 12 or the stepped insert tube 66. During the process, the semicircular plug block 58 stretches the fourth spring 64. During the extension and reset process of the second electric telescopic rod 33, after the inclined surface 63 disengages from the rotating shaft 60, the fourth spring 64 resets, and the semicircular plug block 58 disengages from the slot 65.

[0092] As a detailed description, when the drill bit 2 passes through the through hole 29, the bottom ends of the tap 3 and the remaining two stepped inserts 66 are in contact with the top of the support plate 27. In order to reduce wear and tear, three rubber pads are embedded and fixed on the support plate 27. The three rubber pads are distributed in a circular array with the through hole 29, as shown in the attached figure. Figure 1 and attached Figure 2As shown, the rubber pad can support the bottom ends of the tap 3 and the remaining two step inserts 66, and enable the tap 3 to push the driving disk 12 to slide upward in the tap placement step hole 8, so that the step insert 66 drives the double air chamber box 70 to slide upward in the slot 81. Similarly, in the process of the tap 3 passing through the through hole 29, the bottom ends of the drill bit 2 and the remaining two step inserts 66 are in contact with the rubber pad on the top of the support plate 27. In the process of one step insert 66 passing through the through hole 29, the bottom ends of the drill bit 2, the tap 3 and the other step insert 66 are in contact with the rubber pad on the top of the support plate 27.

[0093] It should be noted that when the stepped insert 66 drives the double air chamber box 70 to slide upward in the slot 81, the air outlet 72 moves upward along the movable slot 75 and gradually separates from the air port 76. During this process, the fifth spring 79 is reset and pushes the sealing plate 78 to block the air port 76. Conversely, when the spline column 40 pushes the second trigger button 80 to squeeze the double air chamber box 70, the double air chamber box 70 will squeeze the sealing plate 78 and compress the fifth spring 79 to achieve the connection between the air outlet 72 and the air port 76.

[0094] As an expanded explanation, when processing a through-hole threaded hole on a door and window component, the extension length of the first electric telescopic rod 16 is controlled, so that the drill bit 2 and the tap 3 in a rotating state can pass through the door and window component and enter the blind hole 30. At this time, waste chips are accumulated in the blind hole 30, and the waste chips can be blown up by the air introduced into the air inlet cavity 68 and discharged from the air outlet cavity 69;

[0095] When processing non-through-hole threaded holes in door and window components, the extension length of the first electric telescopic rod 16 is controlled, and the rotating drill bit 2 and tap 3 are allowed to enter the corresponding depth inside the door and window components according to the depth of the threaded hole. At this time, waste chips are accumulated in the initially processed drill holes and the subsequently processed threaded holes. The waste chips can be blown up by the air introduced into the air inlet cavity 68 and discharged from the air outlet cavity 69.
