Pneumatic portable marking gun along with line

Abstract

The invention relates to a pneumatic portable marking gun along with a line. The marking gun comprises a gun body 1, an air cylinder piston 2, a trigger 3, a firing pin 4 and a steel letter head 6. A cylinder block of an air cylinder is located in a head cavity of a gun body and fixedly connected with the gun body. A return stroke gas storage chamber is formed between the outer periphery of the cylinder block and the inner periphery of the gun body. The air cylinder piston 2 is located in the cylinder block of the air cylinder. One end of the firing pin 4 is fixedly connected with the air cylinder piston 2. The other end of the firing pin 4 is fixedly connected with the steel letter head 6. The steel letter head 6 extends out of the end of the gun body. The extending end of the steel letter head 6 is slidably inserted into a guiding groove of a directional guiding rail. An inner cavity of a gun stock serves as a compressed air cavity 9. The two ends of the compressed air cavity 9 communicate with a left control cavity and a gas source correspondingly. When the pneumatic portable marking gun along with the line is used, the marking gun does not need to dismounted from the production line, the line following performance is good, the flexibility is high, the advantages of flexibility, rapidness and convenience of semi-automatic and manual marking are combined, and marking can be completed by one hand of one person.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a pneumatic portable on-line marking gun. Background technique [0002] Marking is to identify the parts after the hydrostatic test is an important part of the process to distinguish the state of the parts and ensure the quality. At present, there are generally two marking methods used in the market. One is the traditional manual marking method, that is, the operator puts the steel head on the surface of the part to be marked with one hand, and lifts the hammer with the other hand to strike the steel head hard. The first method is to complete the marking; the other is to use a special pneumatic marking machine or laser marking and other special devices for marking. The characteristics of using a marking machine or manual marking: due to the limitation of the working surface or production line space, All kinds of marking machines cannot be placed along t...
