Description

Technical Field

[0001] The utility model relates to the technical field of air cannon brackets, in particular to an easy-to-use air cannon fixing device. Background Art

[0002] A pneumatic cannon is a common tool. It gets its name because it makes a loud noise like a cannon when working. It is also called a pneumatic wrench. It is mainly used to remove and install nuts on motor vehicles. The pneumatic cannon uses the compressed air output by the air compressor. The compressed air enters the pneumatic cannon cylinder to drive the impeller inside to rotate and generate rotational force. At the same time, the impeller drives the connected striking parts to perform a hammering motion. After each strike, the screw is tightened or removed. It has been widely used in assembly and maintenance, and production lines in industries such as automobile maintenance, automobile manufacturing, mining, mines, woodworking machinery, etc. It is an efficient and safe pneumatic tool for removing and installing screws.

[0003] The force generated by a large pneumatic cannon is equivalent to the force of two adults using a wrench more than two meters long to tighten a screw. Its force is directly proportional to the pressure of the air compressor. The greater the pressure, the greater the force generated. Therefore, once the pressure is too high, the screws are easily damaged when tightening. Common pneumatic cannons are not easy to operate. When using a pneumatic cannon to remove the screws, because the pneumatic cannon is relatively bulky, it is necessary to manually lift the pneumatic cannon to align the position to remove the nut on the component. The operator needs to lift the pneumatic cannon to operate, which not only causes sore arms to the operator, but also is difficult to operate and even poses a safety hazard, greatly increasing the workload of the operator. It will cause fatigue to the operator for a long time, thereby reducing work efficiency and causing great inconvenience to the user.

[0004] At present, air cannons are generally used in conjunction with brackets when in use, and common brackets for air cannons are not easy to disassemble, and the air cannons are completely fixed on the brackets or are an integrated structure with the brackets. For places where it is inconvenient for the brackets to enter or reach, the air cannons that are integrated with the brackets cannot be used and need to be disassembled for use. It takes a lot of time and energy to disassemble them, which greatly increases the labor intensity of the operators and reduces the practicality of the brackets for air cannons. In addition, after the air cannons are separated from the brackets, they cannot be used with the help of the brackets, which makes it very laborious for the operators to use them.

[0005] Some patents in the field of air cannon technology are disclosed in the prior art. Among them, the utility model patent with publication number CN210757584U discloses an air cannon bracket that is easy to operate, including a base plate, a vertical plate is fixedly connected to the right side of the top of the base plate, a horizontal plate is fixedly connected to the top of the left side of the vertical plate, rollers are arranged at the four corners of the bottom of the base plate, a fixing groove is opened at the bottom of the right side of the vertical plate, a fixing block is arranged on the right side of the fixing groove, the left side of the fixing block passes through the fixing groove and extends into the inside thereof, a fixing shaft is fixedly connected to the right side of the fixing block, a handle is fixedly connected to the right end of the fixing shaft, a winding wheel is fixedly connected to the surface of the fixing shaft, a fixing rope is wound around the surface of the winding wheel, and the top of the vertical plate is fixedly connected to A first pulley adapted to the fixed rope, a second pulley adapted to the fixed rope is fixedly connected to the left side of the top of the horizontal plate, an end of the fixed rope away from the winding wheel passes through the first pulley, the second pulley and the horizontal plate in sequence and extends to the bottom of the horizontal plate and is fixedly connected to the main body of the blaster, a connecting block is fixedly connected to the right side of the main body of the blaster, a slide groove is provided on the top of the left side of the vertical plate, the top and bottom of the inner wall of the slide groove are fixedly connected by a sliding rod, a slider is provided on the surface of the sliding rod, the bottom of the slider is in contact with the bottom of the inner wall of the slide groove, the left side of the slider passes through the slide groove and extends to the outside thereof, a limit block adapted to the connecting block is fixedly connected, the bottom of the limit block passes through the connecting block and extends to the outside thereof, and a push plate is fixedly connected to the right side of the bottom plate.
