Description

Technical Field

[0001] This utility model relates to the field of tapping equipment technology, specifically an automatic tapping device for a door body fixed shaft. Background Technology

[0002] Tapping refers to the process of creating internal threads during machining, also known as internal thread processing. This process is very common in fields such as mechanical manufacturing and mold making. The door fixing shaft is the shaft around which the door rotates when it is opened and closed. Nowadays, it is mostly a metal hinge or hinge, and it is mostly an independent component that needs to be installed on the door panel with screws. Therefore, tapping equipment is needed in the production of fixing shafts.

[0003] The prior art, disclosed in CN213702076U, describes an angle-adjustable workpiece tapping device. This device performs tapping operations on a single workpiece at a time, requiring each workpiece to undergo a complete loading, tapping, and unloading process. This results in long processing intervals between workpieces, reducing processing efficiency. Furthermore, the device requires manual assistance for loading and unloading, which can easily cause hand injuries from contact with the tap and other materials. Additionally, the lack of external protection for the equipment allows tapping debris to easily fly out, posing a significant safety hazard. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies, such as low production efficiency and high risk, and to provide an automatic tapping device for door body fixing shafts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic tapping device for a door body fixing shaft, comprising a base, a bracket fixedly connected to the rear side of the base, and a movable plate slidably connected to the front side of the bracket, a telescopic cylinder fixedly connected to the bracket, the telescopic cylinder being located above the movable plate, and the telescopic end of the telescopic cylinder being fixedly connected to the movable plate, a motor fixedly connected to the front side of the movable plate, and a tap fixedly connected to the bottom output end of the motor, a rotary cylinder fixedly connected to the base, and a support base fixedly connected to the output end of the rotary cylinder, the support base being located below the tap, and placement grooves being provided at both ends of the top of the support base.

[0006] As described above, the two placement slots are equipped with clamping blocks, and screws are movably connected to the clamping blocks. Threaded holes are opened at both ends of the support base, and the screws pass through the threaded holes and are fixedly connected to knobs.

[0007] As described above, a fixed tube is fixedly connected to the front side of the movable plate. The fixed tube is located below the motor, and a movable tube is provided below the fixed tube, with the movable tube inserted into the fixed tube.

[0008] As described above, the top of the fixed tube is closed and has an opening, and a spring is fixedly connected between the movable tube and the fixed tube. The tap passes through the opening and the inside of the movable tube in sequence.

[0009] As described above, the support base is provided with a first baffle that is fixedly connected to the base. The first baffle is L-shaped and has a through hole at the top.

[0010] As described above, the base has a cavity, the top of the cavity has an opening, a number of bristles are fixedly connected inside the perforation, an air pump is fixedly connected to the base, and an air jet pipe is fixedly connected to the air pump and fixedly connected to the bottom of the baffle, and an air outlet is provided on the air jet pipe.

[0011] As described above, a second baffle is provided on the front side of the motor. The second baffle is fully transparent and is fixedly connected to the movable plate. A slot is provided at the bottom of the second baffle.

[0012] Compared with existing technologies, this automatic tapping device for fixing the shaft of a door body has the following advantages:

[0013] I. This utility model sets up a support base with two placement slots to hold two workpieces, with one of the placement slots located below the tap. The support base is driven to rotate by a rotary cylinder, which allows for loading, unloading, and tapping operations on the two workpieces separately, shortening the processing interval between the two workpieces and improving production efficiency.

[0014] Second, this utility model sets up a support base and drives the support base to rotate through a rotary cylinder, so that the placement groove can be moved away from the tap, thereby separating the workpiece loading and unloading from the tap and other components, avoiding contact between the hands and the tap, etc. At the same time, a second baffle is set up to separate the tap and workpiece from the outside world during tapping, preventing debris from flying and improving safety.

[0015] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-5 As shown, this utility model provides a technical solution: an automatic tapping device for a door body fixing shaft, including a base 1, a bracket 2 fixedly connected to the rear side of the base 1, and a movable plate 6 slidably connected to the front side of the bracket 2. A telescopic cylinder 3 is fixedly connected to the bracket 2, the telescopic cylinder 3 is located above the movable plate 6, and the telescopic end of the telescopic cylinder 3 is fixedly connected to the movable plate 6. A motor 7 is fixedly connected to the front side of the movable plate 6, and a tap 10 is fixedly connected to the bottom output end of the motor 7. A rotary cylinder 14 is fixedly connected to the base 1, and a support base 5 is fixedly connected to the output end of the rotary cylinder 14. The support base 5 is located below the tap 10, and a placement groove is provided on the top of the support base 5 near both ends.

[0024] According to the overall structure of the device, a fixed shaft is placed in the placement slot. The support base 5 is rotated 180° by the rotary cylinder 14 to move the workpiece under the tap 10. Then, the telescopic cylinder 3 pushes the movable plate 6 down. The movable plate 6 drives the tap 10 down through the motor 7. At the same time, the motor 7 drives the tap 10 to rotate to tap the workpiece. At this time, another workpiece can be placed in the placement slot at the other end of the support base 5. When the tapping of the previous workpiece is finished, the telescopic cylinder 3 drives the movable plate 6 up to reset the motor 7 and the tap 10. At the same time, the rotary cylinder 14 drives the support base 5 to rotate again to move the next workpiece under the tap 10. The previous workpiece is removed for easy removal.

[0025] like Figure 3As shown, there are clamping blocks 12 in the two placement slots, and screws 13 are movably connected to the clamping blocks 12. Threaded holes are opened at both ends of the support base 5, and the screws 13 pass through the threaded holes and are fixedly connected to the knobs.

[0026] By rotating the screw 13 with the knob, the clamping block 12 moves toward or away from the workpiece, thereby clamping or releasing the workpiece. The structure is simple, the operation is convenient, and it is easy to load and unload workpieces.

[0027] like Figure 2 , 4 As shown, a fixed tube 8 is fixedly connected to the front side of the movable plate 6. The fixed tube 8 is located below the motor 7. A movable tube 9 is provided below the fixed tube 8 and is inserted into the fixed tube 8. The top of the fixed tube 8 is closed and has an opening. A spring is fixedly connected between the movable tube 9 and the fixed tube 8. A tap 10 passes through the opening and the inside of the movable tube 9 in sequence. A first baffle 11 is fixedly connected to the base 1 above the support base 5. The first baffle 11 is L-shaped and has a through hole at the top.

[0028] When the telescopic cylinder 3 pushes the motor 7 and tap 10 downwards, the movable tube 9 first contacts the first baffle 11. Under pressure, the movable tube 9 retracts into the fixed tube 8 and compresses the spring, exposing the tap 10. The tap 10 then passes through the hole to tap the workpiece below. Afterwards, when the tap 10 moves upwards to reset, under the thrust of the spring, the movable tube 9 extends out of the fixed tube 8 and fits over the outside of the tap 10, thus isolating the tap 10 from the outside world and protecting it from damage caused by collisions with external objects.

[0029] like Figure 3 , 5 As shown, a cavity is provided on the base 1, and an opening is provided at the top of the cavity. Several bristles are fixedly connected inside the perforation. An air pump 16 is fixedly connected to the base 1, and an air jet pipe 15 is fixedly connected to the bottom of the baffle on the air pump 16. An air outlet is provided on the air jet pipe 15.

[0030] Air pump 16 and air jet pipe 15 can be used to blow air onto tap 10, thereby blowing off the debris produced during tapping and the debris attached to tap 10, so that the debris falls from the opening into the cavity and is collected in the cavity for easy subsequent debris cleaning.

[0031] like Figure 1 As shown, a second baffle 4 is provided on the front side of the motor 7. The second baffle 4 is fully transparent and is fixedly connected to the movable plate 6. A slot is provided at the bottom of the second baffle 4.

[0032] The second baffle 4 separates the tap 10 from the workpiece and the outside world, preventing chips from flying during tapping and avoiding damage to workers. The tapping process can also be observed through the transparent second baffle 4.

[0033] Working principle: Connect the device to an external power source, place the fixed shaft in the placement slot, rotate the screw 13 to clamp the workpiece with the clamping block 12 for fixation, drive the support base 5 to rotate 180° through the rotary cylinder 14 to move the workpiece below the tap 10, then start the telescopic cylinder 3 and the motor 7 to move the tap 10 down to tap the workpiece. At this time, another workpiece can be placed in the placement slot at the other end of the support base 5. After tapping is completed, the tap 10 moves up to reset, the support base 5 rotates again to switch workpieces. Repeat the above operation to shorten the processing interval and improve production efficiency. During the tapping process, when the tap 10 moves down, it drives the second baffle 4 to move down synchronously and separate the tap 10 and the workpiece to prevent debris from splashing outward. At the same time, the air pump 16 and the air jet pipe 15 blow the debris into the cavity, thereby improving safety and facilitating the cleaning of debris.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
