Description

Technical Field

[0001] This utility model relates to the field of door frame positioning and drilling technology, and in particular to a door frame positioning and drilling device for door and window production. Background Technology

[0002] The door frame is the framework structure of the door opening, mainly serving to fix the door leaf and support its normal opening and closing. Therefore, it is necessary to drill holes in the door frame for positioning.

[0003] A drilling and positioning device for aluminum alloy door frames, authorized by publication number "CN210208777U", can clearly define the location on the door frame where holes need to be drilled. The drilling machine passes through the drill hole to perform the drilling work, which can prevent drilling deviation. However, when drilling holes in the door frame, this aluminum alloy door frame drilling and positioning device is prone to contact with the ground, which can damage the drilling tool and increase the limitations of the work. At the same time, when fixing door frames of different sizes, the limited contact area between the fixing base and the door frame leads to unstable fixing of the door frame, which is prone to shaking during the drilling process, thus reducing the quality of work. Summary of the Invention

[0004] This utility model aims to solve the problems existing in the prior art by providing a door frame positioning and drilling device for door and window production, thereby reducing work limitations and improving work quality.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This door frame positioning and drilling device for door and window production includes a frame and a first box. The upper end of the frame is fixedly connected to the first box. A moving mechanism is installed on the lower inner wall of the frame. Both inner walls of the frame are fixedly connected to an electric telescopic rod. The output ends of the electric telescopic rods are fixedly connected to the frame. The inner walls of the frame are fixedly connected to a vertical rod. An adjustment mechanism is installed on the outer wall of the vertical rod. The inner wall of the first box is fixedly connected to a first servo motor through a bracket. The output shaft of the first servo motor is connected to a first threaded rod. Both outer walls of the first threaded rod are rotatably connected to the first box through bearings. The outer wall of the first threaded rod is threadedly connected to a first block.

[0006] To further improve the mechanism, the moving mechanism includes a first cylinder, the bottom of which is fixedly connected to the frame, the output end of which is fixedly connected to a first rack, both outer walls of the first rack meshing with gears, the inner walls of the gears being rotatably connected to the frame via a rotating shaft, the outer walls of the gears meshing with a second rack, the inner walls of the second rack being slidably connected to a second vertical rod, and both ends of the second vertical rod being fixedly connected to the frame.

[0007] Further improvements include the upper outer walls of both the first and second racks being slidably connected to the frame, and the upper ends of both the first and second racks being fitted to the door frame via rubber pads.

[0008] Further improvements include a housing, with both inner walls of the housing slidably connected to a vertical rod, the upper inner wall of the housing slidably connected to a connecting plate, both lower sides of the connecting plate being movably connected to a connecting rod via pins, and the ends of the connecting rods being movably connected to a support block via pins.

[0009] Further improvements include that the outer walls of the support blocks are slidably connected to the housing, the inner right wall of the housing is threadedly connected to the bolts, and the ends of the bolts are pressed against the right support blocks via rubber pads.

[0010] Further improvements include: the outer wall of the first block is slidably connected to the first housing; the lower end of the first block is fixedly connected to the second housing; the inner wall of the second housing is fixedly connected to the second servo motor via a bracket; the output shaft of the second servo motor is connected to the second threaded rod; both outer walls of the second threaded rod are rotatably connected to the second housing via bearings; the outer wall of the second threaded rod is threadedly connected to the second block; the outer wall of the second block is slidably connected to the second housing; the lower end of the second block is fixedly connected to the second cylinder; the output end of the second cylinder is fixedly connected to the electric drill bit; and the inner wall of the middle part of the frame fits against the door frame.

[0011] The beneficial effects of this utility model are as follows: In this utility model, through the cooperation of the moving mechanism and the frame, the output end of the first cylinder extends, driving the first rack to move upward, thereby lifting the door frame upward. When the first rack moves upward, it drives the gears on both sides to rotate, which in turn drives the second racks on both sides to move downward. In this way, the first rack pushes the middle area of ​​the door frame upward. After the lower side of the door frame separates from the frame, the first cylinder is closed. When the door frame moves upward, since the housings on both sides are already fixed to the door frame, they will also move upward along with the door frame, thus ensuring that the door frame remains fixed. Because the first rack pushes the middle area of ​​the door frame, this method allows for positioning and drilling work on both sides of the door frame. The separation of the door frame from the frame prevents the drill bit from contacting the frame and causing damage to the electric drill bit and the frame. When drilling is required in the middle area of ​​the door frame... When drilling, the output end of the first cylinder retracts, causing the first rack to move downwards. As the first rack moves downwards, it drives the gears on both sides to rotate in the opposite direction, causing the second racks on both sides to move upwards. The second racks on both sides move upwards and contact the door frame, thus lifting up the sides of the door frame. Meanwhile, the first rack in the middle separates from the middle of the door frame. Then, a hole can be drilled in the middle area of ​​the door frame. In this way, both the first and second racks can separate the top and bottom of the door frame from the frame. When the first rack is in contact with the middle of the door frame and lifts the door frame, the frame on both sides is hollowed out. When the electric drill bit drills through the sides of the door frame, it will not contact the frame. When the second racks on both sides are in contact with the sides of the door frame and lift the door frame, the middle of the door frame is hollowed out, allowing drilling to be performed in the middle area. This prevents the electric drill bit from damaging the frame and reduces work limitations.

[0012] By adjusting the mechanism and the vertical rod, the connecting plate is pushed downwards. The connecting plate drives two connecting rods to move via a pin. Both connecting rods drive the support blocks to move outwards. When the two support blocks are close to the two sides of the door frame, the connecting plate is stopped. Then, the bolts are tightened so that the rubber pads at their ends press against the upper end of the right support block, thereby adjusting the position of the two support blocks. By adjusting the position of the two support blocks in the above manner, the contact area with the edge of the door frame is increased, thereby increasing the stability of the door frame during drilling and improving the work quality.

The inner wall on the right side of the housing 301 is threadedly connected to the bolt 305. The end of the bolt 305 is pressed against the right support block 304 via a rubber pad.

[0028] Working principle:

[0029] When it is necessary to perform positioning and drilling work on the door frame 17, place the door frame between the two housings 301, and then push the connecting plate 302 downward. The connecting plate 302 drives the two connecting rods 303 to move through the pin shaft. Both connecting rods 303 drive the support blocks 304 to move outward. The two support blocks 304 move outward synchronously in the front-back direction of the equipment. When the position of the two support blocks 304 is close to the two side edges of the door frame 17, stop pushing the connecting plate 302. Then tighten the bolt 305 so that the rubber pad at its end abuts against the upper end of the right support block 304, thereby adjusting the position of the two support blocks 304. By adjusting the position of the two support blocks 304 in the above manner, the range with the edge of the door frame 17 is increased, thereby increasing the stability of the door frame 17 (the adjustment method of the two support blocks 304 on the right is the same as that of the two support blocks 304 on the left). According to the above method, pulling the connecting plate 302 upward will cause the two support blocks 304 to move inward.

[0030] Then, the electric telescopic rods 14 on both sides are activated, causing their output ends to extend. Both electric telescopic rods 14 on both sides drive the frame 15 to move. The two frame 15s move inward, thereby causing the two housings 301s to move inward. The support blocks 304 inside the two housings 301s and the housings 301s fit against the door frame 17, thus fixing the door frame 17. After the door frame 17 is fixed, the electric telescopic rods 14 on both sides are closed. Then, the external power supply of the first servo motor 5 is connected and started. The first servo motor 5 drives the first threaded rod 6 to rotate. The first threaded rod 6 drives the first block 7 to move to the right (the first servo motor...). 5. Reverse rotation will cause the first block 7 to move in the opposite direction. The first block 7 drives the second housing 8 to move, which in turn drives the electric drill bit 13 to move. After the electric drill bit 13 moves to the required drilling position on the door frame 17, the first servo motor 5 is turned off, and then the second servo motor 9 is turned on. The second servo motor 9 drives the second threaded rod 10 to rotate, and the second threaded rod 10 drives the second block 11 to move to the right (reversing the second servo motor 9 will cause the second block 11 to move in the opposite direction). The second block 11 drives the second cylinder 12 to move, which in turn drives the electric drill bit 13 to move (due to...). Figure 4 for Figure 3 The side view, so the second block 11 is in Figure 2 and Figure 3 The electric drill bit 13 moves forward and backward (and thus the electric drill bit 13 moves forward and backward). In summary, the electric drill bit 13 can be adjusted in the front, back, left and right directions by the first servo motor 5 and the second servo motor 9, so that the electric drill bit 13 can be moved to the position where the door frame needs to be drilled.

[0031] Then, the external power supply to the first cylinder 201 is connected and started. The output end of the first cylinder 201 extends, driving the first rack 202 to move upward, thereby lifting the door frame 17 upward. When the first rack 202 moves upward, it drives the gears 203 on both sides to rotate, thereby driving the second racks 204 on both sides to move downward. In this way, the first rack 201 pushes the middle area of ​​the door frame 17 upward. After the lower side of the door frame 17 separates from the frame 1, the first cylinder 201 is closed. When the door frame 17 moves upward, the first cylinder 201 is turned off. Since the housings 301 on both sides are fixed to the door frame 17, when the door frame 17 moves upward, the housings 301 on both sides will also move upward with the door frame 17, thus ensuring that the door frame 17 is always fixed. Since the first rack 201 pushes the middle area of ​​the door frame 17, the above method can be used to position and drill holes on both sides of the door frame 17. Separating the door frame 17 from the frame 1 can prevent the drill bit 13 from contacting the frame 1 and causing damage to the electric drill bit 13 and the frame 1. When it is necessary to drill the middle area of ​​the door frame 17... During drilling, the output end of the first cylinder 201 retracts, causing the first rack 202 to move downwards. As the first rack 202 moves downwards, it drives the gears 203 on both sides to rotate in the opposite direction, causing the second racks 204 on both sides to move upwards. The second racks 204 on both sides move upwards and contact the door frame 17, thus lifting the sides of the door frame 17. Meanwhile, the first rack 202 in the middle separates from the middle part of the door frame 17. Then, a hole is drilled in the middle area of ​​the door frame 17. Through the above method, both the first rack 202 and the second rack 204... The top and bottom of the door frame 17 can be separated from the frame 1. When the first rack 202 fits against the middle of the door frame 17 and lifts the door frame 17, the frame 17 on both sides is hollowed out. When the electric drill bit 13 drills through the areas on both sides of the door frame 17, it will not contact the frame 1. When the second rack 204 on both sides fits against the sides of the door frame 17 and lifts the door frame 17, the middle of the door frame 17 is hollowed out, so that drilling can be carried out in the middle area, thereby preventing the drill bit 13 from damaging the drill bit and the frame 1 when drilling.

[0032] The external power supply of the electric drill bit 13 is connected and started. The external power supply of the second cylinder 12 is also connected and started. The output end of the second cylinder 12 extends, causing the electric drill bit 13 to move downward. The drill bit of the electric drill bit 13 contacts the door frame 17 and drills a hole in it. After the door frame 17 is drilled, the output end of the second cylinder 12 retracts, causing the electric drill bit 13 to reset. After the electric drill bit 13 resets, the reset is turned off. The positioning and drilling work of the door frame 17 is completed in the above manner. Then, the output ends of the two electric telescopic rods 14 retract, causing the two housings 301 to separate from the door frame 17 and thus canceling the fixation of the door frame 17. After the door frame 17 is unfixed, the two electric telescopic rods 14 are turned off. Then, the worker can remove the drilled door frame 17. The positioning and drilling work of the door frame 17 is completed in the above manner.
