Background technology
Pressure cooker comprises pressure cooker body and pressure cooker cover two large divisions.China Patent No. be 2014203129594, Authorization Notice No. is cn203987515U, authorized announcement date be December 10 in 2014 day, be called in the patent document of " a kind of pressure cooker cover with visual window " and namely disclose a kind of pressure cooker cover, safety valve and relief valve on pressure cooker cover, the valve pipe of above-mentioned valve is connected to pressure cooker cover in a welding manner.Weld by electric welding machine is capable during the upper valve pipe of existing pressure cooker cover.China Patent No. be 2013202571770, Authorization Notice No. is cn203292661U, authorized announcement date be November 20 in 2013 day, be called in the patent document of " a kind of electric welding machine " and namely disclose a kind of existing electric welding machine.Can only be welded by welding gun again by artificial valve pipe being fixed after on the corresponding position that is shelved on pressure cooker cover when being carried out the valve pipe on welding pressure pot cover by existing electric welding machine, not only waste time and energy during welding but also cause owing to easily producing jitter phenomenon during artificial standing valve pipe the uniformity of weld strength difference and quality poor.
Summary of the invention
The invention provides a kind of conforming pressure cooker cover valve pipe bonding machine that can improve weld strength and welding quality, solve and manually valve pipe is welded to weld strength existing on pressure cooker cover and the problem of quality consistency difference.
Above technical problem is solved by following technical proposal: a kind of pressure cooker cover valve pipe bonding machine, comprise electric welding machine and spot-welding gun, described electric welding machine is provided with two electrodes, described spot-welding gun is electrically connected with an electrode in described two electrodes, it is characterized in that, also comprise the lower bolster set gradually from bottom to top, conducting block, suspension plate and cope match-plate pattern, described lower bolster is provided with the locating piece for carrying out supporting and location to pressure cooker cover, described suspension plate is liftably linked together with described cope match-plate pattern by cylinder, described conducting block is connected to described suspension plate, described conducting block is electrically connected with another electrode in described two electrodes, described spot-welding gun is connected to described suspension plate, described spot-welding gun is provided with valve pipe fixation structure.During use, pressure cooker cover is covered on locating piece, valve pipe is linked together with welding gun by valve pipe fixation structure, then electric welding machine and cylinder is driven, air cylinder driven suspension plate drop to conducting block be connected to valve Guan Doutong valve pipe together with after then stop declining, then electric welding machine formation loop thus valve pipe is welded on pressure cooker cover when conducting block contact with valve Guan Doutong pressure cooker cover.Do not need artificial standing valve pipe and transfer point welding gun, easily laborsaving during use, the valve pipe of weld is good and quality consistency is good with the bonding strength between pressure cooker cover.
As preferably, described spot-welding gun comprises inner core and the perpendicular overcoat put, the upper end telescopically of described inner core is located in described overcoat, described inner core is provided with and prevents inner core from from described overcoat, deviating from limited block downwards, inner core back-moving spring is provided with between described overcoat and inner core, described overcoat links together with described suspension plate, and described valve pipe fixation structure is arranged at described inner core.When the length violation that valve pipe in assembling process stretches out spot-welding gun close partially long and cause valve pipe to touch pressure cooker cover prior to conducting block time, inner core can drive valve pipe shrink together and dodge, thus avoids conducting block different pressures pot cover to contact and cause the phenomenon that can not weld to produce.This technical scheme can reduce the installation requirement of valve pipe, improves convenience during use.
As preferably, described valve pipe fixation structure comprises the valve pipe installing hole extended along the vertical direction being arranged at described inner core lower end.Convenience during standing valve pipe is good.
As preferably, described valve pipe installing hole is arranged at the lower surface of described inner core.Interfere with overcoat when valve pipe can be avoided to shrink, for the cramped construction design of spot-welding gun is laid a good foundation.
As preferably, described valve pipe fixation structure also comprises the holddown spring on the briquetting that telescopically is connected to the hole wall of described valve pipe installing hole and the valve pipe driving briquetting to be pressed to be arranged in valve pipe installing hole.By after valve pipe is inserted valve pipe installing hole then briquetting can automatically by being pressed on valve pipe, valve pipe be fixed, facilitate during standing valve pipe.
As preferably, the hole wall of described valve pipe installing hole is provided with cooling liquid outlet, cooling sap cavity is provided with between described overcoat and inner core, described inner core is provided with the seal section be movable in described cooling sap cavity be sealed connected together with described overcoat, the position that described seal section can extend in described cooling sap cavity is provided with cooling liquid inlet, described interior in-core is provided with the runner being communicated with described cooling liquid inlet and cooling liquid outlet, and described briquetting extends described runner and forms the spool of runner described in folding.During use, valve pipe touches pressure cooker cover prior to conducting block.Inner core collapses is that cooling liquid inlet is communicated with cooling sap cavity, and the cooling fluid in cooling sap cavity flow in runner, and when briquetting is connected to together with valve pipe, runner disconnects by briquetting, and cooling fluid can not flow out thus can not affect welding.Welded and on when carrying spot-welding gun, on the one hand inner core the importance of back-moving spring reset and make cooling liquid inlet again other overcoat close, when interior pipe is extracted and staggers with briquetting, briquetting loses the partition effect to runner under by the effect of pressing spring, cooling fluid in runner flows out to Cooling Quenching valve pipe realized to covering through cooling liquid outlet, thus can acceleration valve pipe cooling and improve the intensity of weld.Achieve cooling automatically and quenching.
As preferably, described cooling liquid outlet is positioned at the below of described briquetting.This position relationship makes airduct first stagger with stagger day after tomorrow cooling liquid outlet of briquetting, can effectively avoid cooling fluid flow into the inside of airduct and cause cooling effect quenching effect to be deteriorated.
As preferably, described cooling liquid outlet is the ring channel structures extended along the circumference of valve pipe installing hole.In quenching process, the whole circumference of valve pipe can both be cooled, and liquid waters, uniformity when cooling is good, avoids producing valve pipe weld circumference quenching non-uniform phenomenon.
Preferred as another, described valve pipe fixation structure comprises the magnet for adsorbing valve pipe.
Preferred as another, described valve pipe fixation structure comprises at least two panels resilient clamp lobe and the outer hoop that resilient clamp lobe closed up of hoop in all resilient clamp lobe outsides.
