Description
Technical field
The present invention relates to a kind of combustion-type driver, particularly a kind of combustion air nail gun.
Background technology
At present, at on the market combustion air nail gun is to bear hitting power with plastic casing all, wherein the endoporus of plastic casing bottom cooperates the location with the cylindrical of cylinder bottom, and the bottom of cylinder is to be positioned on the step of plastic casing, because the not machinability of plastic casing and the distortion after the plastic shaping and change in size all can cause the axial line disalignment of cylinder axial line and plastic casing, and can cause cylinder to change, and make the installation of cylinder and ailhead seat also axial deviation can take place in axial size.In addition, cylinder heads of all combustion air nail guns all are to be connected with pre-buried screw on the plastic casing top in the market, cause cylinder head and cylinder occurrence positions to be offset like this.The high temperature that causes owing to igniting, burning, blast in the use of whole combustion air nail gun can make its plastic casing take place softening and expand, and has caused this product that change in size in use all can take place, or length variations.And even more serious be: each igniting blast all can make plastic casing axially impact, and the trend of drawing crack is arranged.Behind the general nailing tens0000 times, this plastic casing will break.
Summary of the invention
Purpose of the present invention just provides that a kind of can to cancel plastic casing stressed, improves the service precision and the combustion air nail gun in service life.
To achieve these goals, by the following technical solutions: a kind of combustion air nail gun, the adiabatic outer cover that comprises cylinder block and cylinder block outside, it is characterized in that: the circumference external diameter of described cylinder block is provided with plural connection boss, have the passage that air communication is crossed between the connection boss, connect boss and link to each other with terminal pad, wherein the bar-shaped trough that has air communication to cross on the terminal pad by bolt, one end of joint pin is connected on the terminal pad, and the other end links to each other with the cylinder head that is positioned at cylinder block top.
Wherein has the location annulus on the outer rim of terminal pad, the bottom of cylinder block has hangnail, the adiabatic outer cover of cylinder block outside is divided into heat insulation upper shield and two parts of heat insulation lower shield, the lower diameter of heat insulation lower shield is less than upper diameter, wherein the upper end of heat insulation upper shield is sandwiched between cylinder head cover and the cylinder head, the lower end is installed on the one side of the location annulus of terminal pad, and heat insulation lower shield upper end is installed on the another side of the location annulus of terminal pad, and heat insulation lower shield lower end is blocked by hangnail.
The inwall of described heat insulation upper shield is provided with the retainer of the half opening that holds joint pin.
Described heat insulation upper shield armrest has a side chamber that the gas cylinder and the lever of calming the anger are installed, this chamber and heat insulation upper shield are a monolithic construction, because the retainer of half opening makes its this chamber can well guarantee the position of gas cylinder with the firm connection of joint pin and cylinder head, terminal pad.
Have end play between the upper end of described heat insulation upper shield and cylinder head cover and the cylinder head, have radial clearance between the outer wall of heat insulation lower shield lower end and cylinder block.
This invention project organization compactness, easy, accurate positioning between the parts, positioning accuracy height, the antifatigue impulsive force is strong, can prolong the service life of product, cuts down finished cost.

The specific embodiment
The present invention will be further described below in conjunction with the drawings and specific embodiments.
Extremely shown in Figure 6 as Fig. 1, a kind of combustion air nail gun, the adiabatic outer cover that comprises cylinder block 5 and cylinder block outside, the circumference external diameter of described cylinder block 5 is provided with plural connection boss 5-1, have the passage that air communication is crossed between the connection boss 5-1, connect boss and link to each other the bar-shaped trough 4-1 that wherein has air communication to cross on the terminal pad by bolt with terminal pad 4, one end of joint pin 8 is connected on the terminal pad 4, and the other end links to each other with the cylinder head 2 that is positioned at cylinder block top.Wherein has location annulus 4-2 on the outer rim of terminal pad, the bottom of cylinder block has hangnail, the adiabatic outer cover of cylinder block outside is divided into heat insulation upper shield 3 and 6 two parts of heat insulation lower shield, the lower diameter of heat insulation lower shield is less than upper diameter, wherein the upper end of heat insulation upper shield is sandwiched between cylinder head cover 1 and the cylinder head 2, the lower end is installed on the one side of the location annulus of terminal pad, and heat insulation lower shield upper end is installed on the another side of the location annulus of terminal pad, and heat insulation lower shield lower end is blocked by hangnail.Heat insulation upper shield armrest has a side chamber 3-2 that the gas cylinder and the lever of calming the anger are installed, this chamber and heat insulation upper shield are a monolithic construction, because the retainer of half opening makes its this chamber can well guarantee the position of gas cylinder with the firm connection of joint pin and cylinder head, terminal pad.
During installation, heat insulation lower shield is installed from bottom to up, just can be fixed.The inwall of heat insulation upper shield is provided with the retainer 3-1 of the half opening that holds joint pin, and joint pin can be embedded in the retainer like this, has guaranteed the fixing of heat insulation upper shield.Have end play between the upper end of heat insulation upper shield and cylinder head cover and the cylinder head, have radial clearance between the outer wall of heat insulation lower shield lower end and cylinder block.So in use the expansion of the heat insulation outer cover of plastics cause can not influence the serviceability of this product and change in size because temperature raises.
In this invention, heat insulation outer cover only plays heat insulation effect, does not have support function, even just heat insulation outer cover is removed, does not also influence the function of nail rifle at all.
Because it is ingenious, easy to process to have adopted technique scheme, the present invention to have a design, makes the precision height, prolongs the service life of whole nail rifle.
