Problems solved by technology
However, since the bottom of the gun needle piston hits once, the buffer rubber will be forcibly compressed once. In the case of continuous high-frequency impact compression, the buffer rubber is compressed and deformed, making its internal molecules rub against each other, generating high heat, making the buffer Glue accelerates damage from deformation to qualitative change
Even, finally cause buffer failure, affect the normal work of the gun head, at this time, then need to replace the buffer rubber in time, bring trouble to the user

The invention relates to an air cushion buffering structure of a gun head of a nailing machine. The air cushion buffering structure comprises a gun body, a gun needle assembly and a gun nozzle assembly, wherein the gun needle assembly is movably arranged in the gun body; the gun nozzle assembly is arranged at one end of the gun body; an air cushion buffering device is arranged between the gun body and the gun nozzle assembly. The air cushion buffering device is arranged between a corresponding cylinder body in a gun shell of the gun head of the nailing machine and the gun nozzle assembly; when a gun needle is inserted into a gun nozzle, the air cushion buffering device forms an air cushion; the air cushion is further compressed to form an air cushion buffer; hard collision between a piston of the gun needle and the inner end face of a position, which is close to the gun nozzle assembly, of the gun body is avoided, so that the piston of the gun needle and other parts in the gun body can be well protected.
Description
technical field [0001] The invention relates to the technical field of pneumatic nailing machinery, in particular to an air cushion structure for a nailing gun head. Background technique [0002] The gun head of the existing nailing machine includes a gun housing, a control valve, a cylinder, a gun nozzle assembly and a gun needle, the cylinder is arranged in the gun housing, the gun housing is provided with an air inlet and an exhaust passage, and the control valve is arranged at the air inlet. Between the air inlet and the exhaust passage, the air inlet and the exhaust passage communicate with the inside of the cylinder through the control valve, and the nozzle assembly is arranged at one end of the gun shell and communicates with the inside of the cylinder. The cylinder includes a cylinder body and a needle piston, the needle piston is arranged in the cylinder body, one end of the needle is connected with the needle piston, and the other end of the needle extends into the...
