Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic assembly tools, and particularly relates to a pneumatic assembly tool with adjustable torque and a self-locking mechanism. Background Technique

[0002] Pneumatic assembly tools are very common in the manufacturing and assembly fields. Because they rely on compressed air to provide power, they are usually lighter, more durable and more efficient than electric tools. Moreover, pneumatic assembly tools usually have the characteristics of simple structure, easy maintenance and long working hours, and have important applications in many industrial occasions.

[0003] When a pneumatic assembly tool is in use, since power is provided by the supply of gas, and the torque of the assembly tool is adjusted by the input size of the gas, so as to facilitate the assembly of different objects. However, when the assembly tool is in assembly, the assembly head rotates rapidly, and the gas supply is also continuously supplied. Once a safety problem occurs, it is difficult to cut off the gas supply. The continuously rotating assembly head will still rotate under the input of gas, and it is very difficult to lock the device by cutting off the gas supply. Therefore, when an accident occurs, the threat of continuous operation of the device is still difficult to eliminate.

[0004] Therefore, it is necessary to design a pneumatic assembly tool with adjustable torque and a self-locking mechanism to solve the above problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model.

[0019] Obviously, many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0020] Please refer to Figures 1-4, the present utility model provides a pneumatic assembly tool with adjustable torque and a self-locking mechanism, including a pneumatic device body 1. One side of the pneumatic device body 1 for gas connection is communicated with a pneumatic box 3. One side of the pneumatic box 3 is communicated with a nozzle 2. The top of the pneumatic box 3 is fixedly connected with an equipment box 4. Two square openings 19 are respectively opened and communicated between the bottom of the equipment box 4 and the top of the pneumatic box 3. Inside the pneumatic box 3, a gas regulating block 11 is fixedly connected. An air vent is opened on the gas regulating block 11. The two ends of the air vent are respectively communicated with one side of the pneumatic box 3 and one side of the nozzle 2. Inside the air vent, a rotating gas regulating part 13 is arranged. Two gas regulating holes distributed in a cross shape are opened on the gas regulating part 13. One side of the equipment box 4 is fixedly connected with a second servo micro motor 6. A rotating mechanism is arranged on the output shaft of the second servo micro motor 6. One end of the rotating mechanism is fixedly connected to one side of the gas regulating part 13. The top of the equipment box 4 is fixedly connected with a first servo micro motor 5. A threaded rod 8 is fixedly connected to the output shaft of the first servo micro motor 5. One end of the threaded rod 8 inside the equipment box 4 is threadedly sleeved with a threaded sleeve block 7. The bottom end of the threaded rod 8 is rotatably connected to the bottom of the inner cavity of the equipment box 4. The bottom of the threaded sleeve block 7 is fixedly connected with a lifting plate 12. The bottom end of the lifting plate 12 is slidably inserted into the interiors of the equipment box 4, the pneumatic box 3 and the gas regulating block 11. An air outlet 17 and an insertion port 18 are opened at the bottom of the gas regulating block 11. One side of the U-shaped end of the lifting plate 12 is slidably inserted into the interior of the insertion port 18. A control air hole 14 communicated with the air vent is opened on one side of the U-shaped end of the lifting plate 12 inside the insertion port 18. The other side of the U-shaped end of the lifting plate 12 is slidably inserted into the interior of the air outlet 17. An exhaust port 16 is opened at the bottom of the pneumatic box 3. When the air pump is connected through the nozzle 2 to supply gas to the pneumatic device body 1, by starting the second servo micro motor 6, the gas regulating part 13 is driven to rotate by the rotating mechanism. Thus, by adjusting the positions of the two gas regulating holes on the gas regulating part 13, the size of the gas supply inside the pneumatic device body 1 is adjusted, so as to realize the control and adjustment of the torque inside the pneumatic device body 1. When supplying gas, by starting the first servo micro motor 5, the threaded rod 8 rotates, so as to drive the lifting plate 12 to lift and lower at the air vent of the gas regulating block 11. Thus, by adjusting the position of the control air hole 14, whether to supply gas to the interior of the pneumatic device body 1 is controlled, so as to achieve the self-locking function. When the lifting plate 12 rises, the control air hole 14 is flush with the air vent, for normal supply to the interior of the pneumatic device body 1. At this time, the other end of the lifting plate 12 is inserted into the interior of the air outlet 17 to avoid gas leakage. When the lifting plate 12 descends, the control air hole 14 gradually disengages from the air vent and is gradually blocked by the upper half of the lifting plate 12. When it is completely blocked, at this time, the end of the lifting plate 12 inserted into the air outlet 17 disengages from the air outlet 17, so that the supplied gas is discharged from the air outlet 17 on the gas regulating block 11.And it is continuously discharged to the outside through the exhaust port 16. At this time, the air supply of the air pump to the pneumatic device body 1 stops, achieving the self-locking function to prevent greater safety hazards caused by continuous air supply and continuous operation of the pneumatic device body 1 in case of accidents.

[0021] It should be noted that the rotation mechanism mentioned in the above description includes two rotating shafts 15. When the second servo micro-motor 6 is turned on, one rotating shaft 15 rotates, and through the meshing of the second gear 10 and the first gear 9, the two rotating shafts 15 rotate synchronously, thereby driving the air regulating member 13 to rotate inside the air vent hole, and thus adjusting the torque of the pneumatic device body 1 by adjusting the position of the air regulating holes of the air regulating member 13.

[0022] In order to facilitate the adjustment of whether the air pump supplies air to the pneumatic device body 1 by adjusting the position of the air control hole 14, the aperture of the air control hole 14 is smaller than that of the air vent hole, and the aperture sizes of the two air regulating holes on the air regulating member 13 are different. In order to more precisely adjust the rotation position of the air regulating member 13, the tooth number ratio of the first gear 9 and the second gear 10 is 5:1, so that the meshing rotation of the first gear 9 and the second gear 10 is a speed-reducing rotation.

[0023] In order to enable the threaded sleeve block 7 to stably lift and slide inside the equipment box 4 when the threaded rod 8 rotates, the threaded sleeve block 7 is slidably arranged inside the equipment box 4, and the threaded sleeve block 7 is a square block, and both sides of the threaded sleeve block 7 are respectively attached to both sides of the inner cavity of the equipment box 4.

[0024] Furthermore, in order to better utilize the rotation of the air regulating member 13 to adjust the gas supply size, the air regulating member 13 is a sphere, and the outer surface of the air regulating member 13 is attached to the outer surface of the air vent hole.

However, the present invention is not limited to the specific details in the above embodiments.

To avoid unnecessary repetition, the present invention does not separately describe various possible combination methods.

[0027] In addition, any combination can be made between various different embodiments of the present invention as long as it does not violate the idea of the present invention, and it should also be regarded as the content disclosed by the present invention.
