Abstract

A pneumatic riveting machine relates to an improved device of a buffer structure, comprising a handle (1) which is spirally connected with an impact gun body (2), the handle (1) is provided with an air inlet control device, the impact gun body (2) is axially provided with a cavity (3), the cavity is divided into two parts by an impact head (4) which is arranged in the cavity (3), one part of the cavity is an air pressure pushing cavity and the other part thereof is an impact cavity, the impact gun body is provided with a moving sealing ring (5) for matching, so as to control the air pressure work, the shell wall of the impact gun body is provided with a buffer air duct (6), one end of the buffer duct (6) is communicated with the air pressure pushing cavity, the other end thereof is communicated with an air duct of the handle (1); the pneumatic riveting machine which is designed by the theme of the utility model has simple and reasonable structure, significant buffer effect and reduced labor intensity.

Description

Pneumatic riveter

Technical field

The utility model pneumatic riveter relates to the improvement invention of replying buffer structure after the impact head impact.

Background technology

In existing technology, as utility model patent pneumatic riveter that ZL00247258.9 mentions, structure is provided with advantages of simple, and the working stability tool is reliable, long service life, unique defective is that the answer impulsive force is bigger, workman's feel after long-time assurance is easily tingle, tired, and labour intensity is big, the riveter of need raising one's hand on crossbeam especially nail, the anti-shake of feel is obvious especially, when strong even can't normally use work.

Technical scheme

At the defective that prior art exists, the utility model aims to provide the pneumatic riveter that is provided with buffer structure, reaches the purpose that the vibrations feel is light, reduce labor intensity.

The utility model is to finish as following mode, comprise that the assembling of handle and impact gun body is spirally connected, handle is provided with Intaker controller, axial body cavity is set in the impact gun body, this body cavity is divided into two partly by the impact head of installing within it, impacting first side is that air pressure advances the chamber, opposite side is an impact cavity, the impact gun body is positioned at the sheathed activity seal ring in termination of handle, this activity seal ring and the impact air inlet that is located on the impact gun body are replied air inlet and are opened and closed cooperation, and the impact air inlet is communicated with air pressure and advances the chamber, reply air inlet and be communicated with impact cavity, the shell wall of described impact gun body enters the chamber, replys air inlet and is communicated with impact cavity, and the shell wall of described impact gun body radially is provided with the buffering air flue, this buffering air flue one end is communicated with the air flue of handle, and the other end is communicated with air pressure and advances the chamber;

The diameter of described buffering air flue is 1.5mm～3.5mm.

Press the pneumatic riveter of the utility model theme design, structure is provided with simply, and buffering effect is obvious, holds good hand touch, and labour intensity reduces significantly.

The specific embodiment

Accompanying drawing has been represented the utility model structure, further describe embodiment below in conjunction with accompanying drawing: comprise the assembling that is spirally connected of handle (1) and impact gun body (2), handle (1) is provided with Intaker controller, axial body cavity (3) is set in the impact gun body (2), this body cavity (3) is divided into two partly by the impact head of installing in it (4), impacting head (4) one sides is that air pressure advances the chamber, opposite side is an impact cavity, the impact gun body is positioned at the sheathed activity seal ring in termination (5) of handle, this activity seal ring (5) and the impact air inlet that is located on the impact gun body, reply air inlet and open and close cooperation, impact air inlet and be communicated with air pressure propelling chamber, reply air inlet and be communicated with impact cavity, being provided with of described impact gun body cushions air flue (6), this buffering air flue (6) is partly formed by two, some is an impact gun body radial arrangement, another partly is axial arranged, its diameter that radially cushions air flue is 3.0mm, axial arranged buffering air flue can be provided with the surface of impact gun body, one end of described buffering air flue (6) is communicated with air pressure and advances the chamber, the other end is communicated with the air flue of handle, in order to make buffering reach a desirable effect, assurance has enough distance bufferings, and the rifle body radially cushions the position is set should be slightly less than an axial length that impacts to the distance of its bottom (impacting the impact originating terminal of head) of air flue.
