Component pneumatic fastener machine

Abstract

The modular pneumatic processing device has a main body (10) that is provided in interior of a cylinder, where an oil flow hole (12) is arranged at wall of the cylinder. The oil flow hole is opened or closed by a main control valve (15) that is arranged at the main body. A coupling opening is arranged at rear end of the cylinder. The main body forms positions of two air channels (13) corresponding to a peripheral edge of the coupling opening. and hence ensures cost-effective processing device.

Description

technical field [0001] The invention provides a structural technology related to a hand-held machine tool, which refers to a component-type pneumatic fastener machine, which can integrate and implement fasteners with different operating properties by replacing components. Background technique [0002] Fasteners are basic fastening parts that are widely used in industrial applications. Among fasteners, pull caps (RIVET NUTS) and pull rivets (BLIND RIVETS) are seemingly similar items, but the operation methods and presentation results are completely different. For the relevant structure of the cap pulling machine, please refer to the US patent document "Patent No.US 6,272,899 B1, Pneumatic-hydraulic rivet gun", and for the relevant structure of the nail pulling machine, please refer to the US patent document "Patent No.US 6,651,301B1, Adjustable hand tool with dual functions". [0003] see figure 1 As shown, it is a schematic diagram of the structure of the existing cap pull...

AI Technical Summary

Problems solved by technology

[0008] by the above figure 1 and figure 2 It can be seen that the pneumatic cap pulling machine and the nail pulling machine, which seem to be similar hand-held machine tools, have completely different operating principles. Therefore, it is difficult to implement the integration of the two

For example, when improving on the basis of a pneumatic cap pulling machine, because the pneumatic cap pulling machine must be provided with an air motor driving the screw behind the cap push rod, and when performing nail pulling operations, a considerable stroke is required to accommodate the tail nail or even It is to carry out the operation of discharging the tail nails at the end, so the existence of the air motor will cause structural conflicts with the means of accommodating the tail nails and discharging the tail nails during the nail pulling operation, so the pneumatic cap pulling machine should be used as a There is a considerable degree of difficulty in the use of pull nails

[0009] Conversely, if the improvement is based on the nail pulling machine, since the cap pulling machine must be combined with the pulling cap through the screw at the front end, and the screw must be driven by the setting of the air motor, the setting of the screw and the air motor is It will definitely conflict with the displacement distance of the occlusal fixing part and the push rod of the nail puller originally provided by the nail puller, so it is quite difficult to use the pneumatic nail puller as a cap puller through modification
