Dotting retractable pen cap structure

Abstract

The invention discloses a dotting retractable pen cap structure. The dotting retractable pen cap structure comprises a pen cap of a hollow structure and a dotting pen which is inserted into an inner cavity of the pen cap and can make up-down reciprocating motion relative to the pen cap to achieve dotting for parts. The upper portion of the pen cap is sleeved with a clamping piece which can be connected with a dotter on an engine assembly production line and is adjustable in position, a compression spring used for driving the dotting pen to make reciprocating motion is arranged in the pen cap inner cavity between the clamping piece and the pen cap, and the two ends of the compression spring abut against the positions between the clamping piece and the dotting pen to enable the compression spring to be in a compressed state. The dotting retractable pen cap structure is simple, low in cost and clear and stable in dotting; the dotting pen is manufactured through a finished pen, the clamping piece and the dotter are quickly connected, the pen cap is combined with the clamping piece in a threaded mode, and the compression spring is adjusted to adjust dotting force, so that the pen cap structure is quickly connected with the engine assembly production line, and the problem that extensive-type production lines such as the engine assembly production line cannot conduct dotting is solved.

Description

technical field [0001] The invention relates to the technical field of engine assembly, more specifically, it relates to a dotted retractable pen cover structure. Background technique [0002] The engine assembly line has now entered the stage of intelligent assembly control, and more and more industrial intelligent machines have entered the field of intelligent manufacturing and assembly of engines and other industrial products. Automatic dotting machine is an important element in the field of intelligent manufacturing and assembly. An automatic dotting machine is a machine that performs dotting at a fixed frequency. The dotting technology can be metal probes, industrial etching liquids, high-tech and media such as photoetching, which are expensive and have a single scope of application, and cannot be applied to the assembly line of engines or other extensive low-cost industrial products.
