Description
Technical field
The utility model relates to a kind of valving of clincher tool, particularly a kind of spheroidal stop valve door gear of pneumatic riveting nut instrument.
Background technology
In the domestic and international pneumatic riveting nut instrument, adopt the pass to put trigger usually and reach the riveted joint effect at present, utilize the residual air in the cylinder to promote the air motor reversing, the riveting nut on the pull bar is withdrawed from.But button is put trigger can not be too fast, and the too fast pull bar that then can cause does not also withdraw from riveting nut fully, and instrument will quit work, and this just has a strong impact on riveted joint speed.In addition, though pneumatic riveting nut instrument is more laborsaving than manual riveting nut instrument, work is slow, and efficient is lower, is difficult to adapt to the fast pipeline operation, has to use expensive import instrument than multiple enterprises for this reason.
Summary of the invention
The utility model technical problem to be solved is will provide a kind of can improve riveted joint speed rapidly, resets and the spheroidal stop valve door gear of the pneumatic riveting nut instrument that pull bar withdraws from from riveting nut.
In order to solve above technical problem; The utility model provides a kind of spheroidal stop valve door gear of pneumatic riveting nut instrument; Be installed on the afterbody of pneumatic riveting nut instrument the axis of the piston assembly; Its technical scheme is: described spheroidal stop valve door gear comprises information bar, stroke adjustment assembly, second sealed steel ball, reversing cylinder, reversing piston, middle plunger tip, information valve body, sealing gasket and switching-over compacting ring; Wherein, stroke adjustment assembly the place ahead is connected with the reversing cylinder, and the information valve body is equipped with in reversing cylinder rear end; One root information bar is housed in the information valve body, and there is second sealed steel ball in information bar left side, and the sealing gasket sealing is arranged between it; And be equipped with the switching-over compacting ring locate; In the reversing cylinder reversing piston is housed, reversing piston right side links to each other with the information valve body, and middle plunger tip is equipped with in reversing piston left side.
The superior effect of the utility model is:
1) after pneumatic riveting nut instrument is installed the utility model; Easy and simple to handle, as long as press trigger (under the situation of not loosening trigger) gently, it can accomplish the staking a series of actions of withdrawing from, reset rapidly, steadily, reliably; Whole process is automatic fully, need not manual intervention;
2) improved riveted joint speed rapidly.

The specific embodiment
Below in conjunction with accompanying drawing the structure of the utility model is done further to describe.
Of Fig. 1; The utility model provides a kind of spheroidal stop valve door gear of pneumatic riveting nut instrument; Be installed on the afterbody of pneumatic riveting nut instrument the axis of the piston assembly; Be characterized in: described spheroidal stop valve door gear comprises information bar 16, stroke adjustment assembly 17, second sealed steel ball 18, reversing cylinder 19, reversing piston 20, middle plunger tip 21, information valve body 26, sealing gasket 27 and switching-over compacting ring 28; Wherein, stroke adjustment assembly 17 the place aheads are connected with reversing cylinder 19, and information valve body 26 is equipped with in reversing cylinder 19 rear ends; One root information bar 16 is housed in the information valve body 26, and there is second sealed steel ball 18 in information bar 16 left sides, and sealing gasket 27 sealings are arranged between it; And be equipped with the switching-over compacting ring 28 locate; Reversing piston 20 is housed in the reversing cylinder 19, and reversing piston 20 right sides link to each other with information valve body 26, plunger tip 21 during be equipped with in reversing piston 20 left sides.
The course of work of the utility model: when connecting source of the gas; Do not pressing under the situation of trigger, compressed air gets into from automatic snap joint 1, is divided into two strands; Wherein one flows to by the inclined hole (not shown) in the gun platform and gets in the space of handle 3 and oily steel pipe 4; One then flows to reversal valve 5 in addition, because both sides air pressure is identical about the reversal valve, this moment, reversal valve kept static relatively state.
Press trigger 6, because the rubber of valve inside 7 rear ends is blocked the pore in the handle, the air pressure of reversal valve below is greater than the air pressure of top; Compressed air promotes reversal valve and moves up, and strand air-flow promotes 8 motions of switching-over valve plug in addition, backs down directed ball sealer 9; Compressed air road with the wind gets into breather pipe 10 to cylinder 11 bottoms, jack-up piston 12, and piston drives piston rod 13 hydraulic oil is pressed in the head holder 14; Promote the axis of the piston 15 and rearward move, make that when the axis of the piston is retreated the utility model spheroidal stop valve door gear that is installed in the axis of the piston afterbody is also together retreated; After retreating LAP; The information bar 16 of ball valve stopper rear end moves before propping up stroke adjustment assembly 17 backs, pushes second sealed steel ball 18 open, and compressed air gets into the rear end of reversing cylinder 19 from the position that steel ball is open; And will reverse piston 20 and push the place ahead to; Be contained in the middle plunger tip 21 of reversing on the piston first sealed steel ball 22 of front end is backed down, the compressed air between handle and oily steel pipe road with the wind gets into and promotes the air motor generation in the stator 23 and reverse, and makes pull bar withdraw from the riveting nut of having riveted completion fast.In the air motor reversing, reversing piston 20, can be blocked the air inlet of reversing cylinder 19 behind the segment distance of advancing also promoting forward, and compressed air can't get into reversing cylinder 19 again.
Losing under the situation of air pressure; Switching-over valve plug 8 is return original position; Directed ball sealer 9 is sealed gas circuit again; The air of piston 12 belows is taken advantage of a situation and is flowed to the piston top, simultaneously, is installed in the gas piston spring 24 on the piston and is installed in interior back-moving spring 25 1 same-actions of rifle headstock with the piston returning quickly.
And the riveting nut instrument that the spheroidal stop valve door gear is not installed is being pressed trigger (under the situation about not loosening), can keep the state of pull bar in, is only loosening under the situation of trigger; Pull bar just can reset, in this case, because air mass flow is less when withdrawing from; The normal generation problem that pull bar can not reset fully or reset speed is too slow; Adopt the riveting nut instrument of the utility model spheroidal stop valve door gear, can reach desirable riveted joint effect, improved the operating efficiency of instrument effectively.
