As shown in Figure 2, more than welding gun, the water storage cylinder 4 of water remover is made up of drive unit and water storage device the principle of embodiment one, and control module is First Five-Year Plan mouth three pneumatic operated valves 1, includes robot cooling water interface in addition.The annexation of three is:
Five mouthfuls of three pneumatic operated valves 1 comprise a control end, and its output is made up of the first output 11, second output 12, and also have an input in addition, two intermediate ends, two intermediate ends are all connected with air, jointly constitute the emptying end 13 of control module.The structure of water storage cylinder 4 as shown in Figure 5, wherein water storage device is made up of drive end bearing bracket, sidewall, the first cylinder holes 42, piston 41, and drive unit one to be made up of piston 41, sidewall, baffle plate 47A, the 3rd cylinder holes 46A, driven plunger 45A, the second cylinder holes 44A, rear end cap 43; Baffle plate 47A is fixed on sidewall, can not move on sidewall; Perforate on baffle plate, piston 41 is fixedly connected with the driven plunger 45A bar that is passed baffle plate perforate.The control end spot-welded controller received in spot welding welding system of five mouthfuls of three pneumatic operated valves 1 exports the terminal output of cooling water shutdown signal, then the signal of gas medium is converted to, first output 11 of five mouthfuls of three pneumatic operated valves 1, second output 12 respectively with the second cylinder holes 44A with water storage cylinder 4, 3rd cylinder holes 46A is connected, the input of five mouthfuls of three pneumatic operated valves 1 is connected with compressed air source, compressed air source can use independently compressed gas source, also same compressed gas source can be used with the gas circuit in spot-welded system, but need to ensure no matter when be all provided to Compressed Gas, this gas can be air also can be other gases.More than welding gun in the robot cooling water interface of water remover and spot-welded system, the robot cooling water interface near electrode cap is connected.
When spot-welded system needs to change electrode cap, first stop supply cooling water, now the spot-welded controller of spot-welded system can export cooling water shutdown signal, and be transported to the control end of five mouthfuls of three pneumatic operated valves 1, when five mouthfuls of three pneumatic operated valves 1 receive this signal, connected state can be adjusted to input and the second output 12 conducting, the state of the first output 11 vent gas.The now Compressed Gas of input end, the 3rd cylinder holes 46A of water storage cylinder 4 will be entered by the second output 12 of five mouthfuls of three pneumatic operated valves, now because the second cylinder holes 44A of water storage cylinder 4 is by the first output 11 of five mouthfuls of three pneumatic operated valves 1, emptying end is connected with air, so the air pressure of second cylinder holes 44A one end is lower than the air pressure of the 3rd cylinder holes 46A one end, therefore driven plunger 45A will by the gas push of the 3rd cylinder holes 46A one end, move to the second cylinder holes 44A, because driven plunger 45A and piston 41 link together, piston 41 also can drive by driven plunger 45A, thus move to the direction away from the first cylinder holes 42, now the ponding at electrode cap place is subject to the impact of piston 41 motion, will be inhaled in the water storage device of water storage cylinder 4.
During spot-welded system works, its spot-welded controller does not export cooling water shutdown signal, now five mouthfuls of three pneumatic operated valves 1 make its first output 11 be connected with input, second output 12 is connected with emptying end, the now Compressed Gas of input end, the second cylinder holes 44A of water storage cylinder 4 will be entered by the first output 11 of five mouthfuls of three pneumatic operated valves, now because the 3rd cylinder holes 46A of water storage cylinder 4 is by the second output 12 of five mouthfuls of three pneumatic operated valves 1, emptying end is connected with air, so the air pressure of second cylinder holes 44A one end is higher than the air pressure of the 3rd cylinder holes 46A one end, therefore driven plunger 45A will by the gas push of second cylinder holes 44A one end, move to the 3rd cylinder holes 46A, because driven plunger 45A and piston 41 link together, piston 41 also can drive by driven plunger 45A, thus move to the direction of the first cylinder holes 42, now the ponding at the water storage device place of water storage cylinder 4 is subject to the impact of piston 41 motion, just send back in the water route of spot-welded system, participate in the circulation of cooling water.
This specific embodiment principle is simple, is convenient to understand technical scheme disclosed in this invention.Also be convenient to manufacture.Fig. 3 is the product example that this embodiment makes.
Specific embodiment two, on the basis of specific embodiment one, when the structure of water storage cylinder 4 is constant, makes change to control module, to understand technical scheme disclosed in this invention further.Its principle as shown in Figure 4.
In this embodiment, control module is made up of the first valve 1B, the second valve 2B, the 3rd valve 3A, wherein the first valve 1B, the second valve 2B magnetic valve all for being made up of a control end, an input, an emptying end, an output, when its control end receives a certain signal, the input of magnetic valve and output conducting, when not receiving this signal, the emptying end of magnetic valve and output conducting.
First valve 1B, the output of the second valve 2B are connected with the second cylinder holes 44A, the 3rd cylinder holes 46A of the drive unit cylinder of water storage cylinder 4, the input of the first valve 1B inputs house steward with the cooling water of spot-welded system and is connected, the water inputted is as the drive medium of the drive unit of water storage cylinder 4, the emptying end of the first valve 1B is connected with the cooling water delivery trunk of spot-welded system, for discharging the drive medium of the drive unit of water storage cylinder 4.The input of the second valve 2B is connected with the cooling water delivery trunk of spot-welded system, and emptying end inputs house steward with the cooling water of spot-welded system and is connected.Now, the emptying end of the first valve 1B, the input of the second valve 2B, the emptying end of composition control module, the input of the first valve 1B, the emptying end of the second valve 2B, the input of composition control module, the first output 11 and the second output 12 of the output composition control module of the two.
3rd valve 3A of control module is a check valve, and when its control end receives a certain signal, make input to output one-way conduction, output ends to input; When not receiving this signal, input and output two-way admittance.In this embodiment, the input of the 3rd valve 3A is connected with the first cylinder holes 42 of water storage cylinder 4, more than output and welding gun, the robot cooling water interface of water remover is connected, the cooling water circulation shutdown signal that the spot-welded controller that control end receives spot welding welding system sends.
When the spot-welded controller of spot-welded system does not send cooling water circulation shutdown signal, this signal passes to the first valve 1B by circuit, the control end of the second valve 2B, make input and the output conducting of two valves, cooling water will enter supply mains from the cooling water of spot-welded system, through the input of the first valve 1B, to the output of the first valve 1B, enter the second cylinder holes 44A of the drive unit of water storage cylinder 4, in addition, the drive medium of the driven plunger 45A opposite side of water storage cylinder 4, then by the 3rd cylinder holes 46A, the output of the second valve 2B, input, enter the cooling water outfall sewer of spot welding welding system, thus promotion driven plunger 45A moves to the direction of baffle plate 47A, piston 41 is caused to move to the direction of the first cylinder holes 42 thus, ponding in the water storage device of water storage cylinder 4 is discharged from the first cylinder holes 42, it is made to participate in cooling water circulation.Now, due to the effect of the 3rd valve 3A, the ponding in the water storage device of water storage cylinder 4 can get back to the coolant outlet house steward of spot-welded system by two water routes, so ponding back-flow velocity is faster.
When the spot-welded controller of spot-welded system sends cooling water circulation shutdown signal, cooling water enters supply mains from the cooling water of spot-welded system, through the emptying end of the second valve 2B, output, enter the 3rd cylinder holes 46A of water storage cylinder 4, the drive medium of driven plunger 45A opposite side simultaneously, by the second cylinder holes 44A, the output of the first valve 1B, emptying end, enter the cooling water outfall sewer of spot welding welding system, participation cooling water circulates, thus make driven plunger 45A move to the direction of the second cylinder holes 44A, and drive piston 41, the ponding at the electrode cap place of spot-welded system is made to enter the water storage device of water storage cylinder 4, thus realize goal of the invention, reach technique effect.Meanwhile, because the output of the 3rd valve 3A is cut-off to the direction of input, so water storage cylinder 4 can only attract ponding from electrode cap.
In above two embodiments, drive unit is cylinder, second cylinder holes 44A opens on rear end cap 43, and towards the outer face of driven plunger 45A, so be also between rear end cap 43 and driven plunger 45A, even on driven plunger 45A, towards the outer face perforate of rear end cap 43 as the second cylinder holes, also belong between rear end cap 43 and driven plunger 45A, thus realize goal of the invention, introduce drive medium and promote driven plunger 45A.The principle of the 3rd cylinder holes is also similar.
In addition, two embodiments all on the baffle plate 47A of water storage cylinder 4, towards piston 41, have the 4th cylinder holes 48B, 4th cylinder holes 48B can be used for replacement second cylinder holes 44A and drives driven plunger 45A, utilizes the 4th cylinder holes 48B, can the fault of cylinder body between auxiliary detection second cylinder holes 44A to driven plunger 45A.
In above-described embodiment, control end is all connected to the spot-welded controller of spot-welded system, and the cooling water circulation shutdown signal that receiver sends, with actualizing technology effect.But control end also can not receive the signal of spot welding welding controller, and receive the signal that other signal sources send, as long as this signal correctly can reflect the demand of cooling water circulating open close, also can optionally or the effect of practical application, the signal of reflection cooling water circulating open close is shifted to an earlier date or time delay, so that water storage cylinder 4 Collaboration.In addition, the drive unit of water storage cylinder 4, except above-mentioned three embodiments, although cost intensive, can also adopt the stronger power source of the power such as motor to realize, can reach goal of the invention equally, actualizing technology effect.
