The utility model is characterized in that two grooves are arranged on the lining sleeve, wherein, the O-shaped sealing rings are arranged; two waist-shaped holes are arranged at the lower part of the lining sleeve 4; a groove is arranged on the adjusting rod, wherein, an O-shaped sealing ring; two mutually cross small holes are arranged inside the adjusting rod 3; the upper part of the adjusting rod 3 is connected with the atmosphere; the compression spring 2 is positioned at the upper part of the adjusting rod 3. The structure of the utility model is simple and exquisite, and the use is convenient and reliable.
Description
The utility model relates to a kind of adjusting device of automatic adjusting gas pin gun nailing strength.
Present gas pin gun on the market, its inlet channel area is generally the weighing apparatus definite value, and its nailing strength all is that the rising with the work bleed pressure increases.In actual the use, for some variety of gun, air pressure just can satisfy the requirement of nailing strength when 0.6MPa, but bleed pressure is to change between 0.5～0.8Mpa usually, when air pressure during, will accelerate the damage of the vital part such as striker, cushion pad, ailhead of ailing machine greater than 0.7Mpa.
The purpose of this utility model is to provide a kind of manual adjustment that need not, just can regulate the inlet channel size automatically, make its nailing strength when high pressure remain on a fixed state of basic weighing apparatus, the adjusting device of automatic adjusting gas pin gun nailing strength simple to operate.
The utility model is achieved in that a kind of gas pin gun nailing strength self-checking device, is made up of the O-ring seals of lining, adjusting rod, stage clip and 3 different sizes.It is characterized in that: described lining is provided with two grooves, in establish O-ring seals, the bottom is provided with two mounting holes; Described adjusting rod is provided with a groove, in establish O-ring seals, inside is provided with orthogonal two crossing apertures.
Above-mentioned lining is provided with two mounting holes, enters the inlet channel of piston top for compressed air.
Above-mentioned adjusting rod middle part is provided with a cannelure, and inside is provided with orthogonal two crossing apertures, enters the inlet channel of valve seat, balanced valve top for compressed air.
Above-mentioned stage clip has certain pre compressed magnitude when original state.
During feeding work source of the gas, compressed air enters the adjusting rod bottom through inner orthogonal two the crossing apertures of adjusting rod, and adjusting rod top communicates with atmosphere, and adjusting rod is subjected to the upwards thrust by the compressed air generation, is subjected to the downward elastic force of stage clip simultaneously.When operating pressure during less than 0.5MPa, the suffered upwards thrust design of adjusting rod be that adjusting rod does not move smaller or equal to suffered downward stage clip precompression, and this moment, adjusting rod placed bottom, and the lining inlet channel is a maximum; When operating pressure during greater than 0.5MPa, adjusting rod suffered upwards thrust is greater than suffered downward stage clip precompression, adjusting rod moves up.Adjusting rod lower end major part blocks a lining mounting hole part, and lining inlet channel area is reduced.Along with the rising of operating pressure, displacement that adjusting rod makes progress increases, and lining inlet channel area reduces, and the gases at high pressure flow that enters the piston top reduces, thus the nailing strength fixed function that weighs substantially when realizing high pressure.
The utility model is simple in structure, small and exquisite, and is easy to use, reliable.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1: utility model example structure schematic diagram;
Fig. 2: valve rod profile;
Fig. 3, Fig. 4: lining profile and left view.
A kind of gas pin gun nailing strength self-checking device is made up of lining (4), adjusting rod (3), stage clip (2) and O-ring seals (1), (5), (6) etc.It is characterized in that: described lining (4) is provided with two grooves, in establish O-ring seals (1), (6), the bottom is provided with two mounting holes; Described adjusting rod (3) is provided with a groove, in establish O-ring seals (5), inside is provided with orthogonal two crossing apertures.
Above-mentioned lining (4) is provided with two mounting holes, enters the inlet channel of piston top for compressed air.
Above-mentioned adjusting rod (3) middle part is provided with a cannelure, and inside is provided with orthogonal two crossing apertures, enters the inlet channel of valve seat, balanced valve top for compressed air.
Above-mentioned stage clip (2) has certain pre compressed magnitude when original state.
During feeding work source of the gas, compressed air enters adjusting rod (3) bottom through inner orthogonal two the crossing apertures of adjusting rod (3), and adjusting rod (3) top communicates with atmosphere, adjusting rod (3) is subjected to the upwards thrust by the compressed air generation, is subjected to the downward elastic force of stage clip (2) simultaneously.When operating pressure during less than 0.5MPa, the suffered upwards thrust design of adjusting rod (3) be that adjusting rod (3) does not move smaller or equal to suffered downward stage clip (2) precompression, and adjusting rod this moment (3) places bottom, and lining (4) inlet channel is a maximum; When operating pressure during greater than 0.5MPa, adjusting rod (3) suffered upwards thrust is greater than suffered downward stage clip (2) precompression, adjusting rod (3) moves up.Adjusting rod (3) lower end major part blocks lining (a 4) mounting hole part, and lining (4) inlet channel area is reduced.Along with the rising of operating pressure, displacement that adjusting rod (3) makes progress increases, and lining (4) inlet channel area reduces, and the gases at high pressure flow that enters the piston top reduces, thus the nailing strength fixed function that weighs substantially when realizing high pressure.
The utility model is simple in structure, small and exquisite, and is easy to use, reliable.
