Description
Technical field
The utility model belongs to vehicle body, Frame Welding technical field, specifically, discloses a kind of welding machine self-closing gas dress
Put.
Background technology
It is the welding equipment used in automobile body-in-white welding process to hang mash welder, and matching split type soldering turret is
Pass through compressed air-driven.For using workshop of the suspension mash welder as groundwork equipment, compressed air is main energy sources
One of.Mash welder in the market lacks the module of control compressed air input, causes soldering turret empty in off working state, compression
Gas is persistently supplied, and the cylinder and piston rod of welding machine tracheae, soldering turret, horn easily wear in long-term work, therefore will
Compressed air leakage phenomenon just occurs, so as to cause energy waste.Although can be by closing Manual gas valve, to avoid letting out
Dew, still, because the air valve position is higher, in practice and be inconvenient to operate, and manually to operate every time, in reality
In it is impracticable, therefore the air valve can not solve compressed air leakage problem.
Utility model content
The utility model is overcome the deficiencies in the prior art, adapts to real needs, designs a kind of welding machine self-closing gas dress
Put.
In order to realize the purpose of this utility model, the utility model uses following technological means：
A kind of welding machine automatic gas-off device, including an electric control valve and a set of control circuit, the electric control valve and pressure
The feeder connection of contracting air, the control circuit include the time relay and auxiliary reclay, and the front end of welding machine is soldering turret,
The time relay includes two normally-closed contacts, one of normally-closed contact and electric control valve contact series, another normally closed tactile
Point is connected with soldering turret switch contact；The coil of the auxiliary reclay connects with the valve contact on welder circuit plate and reset contact
Connect, the normally-closed contact of auxiliary reclay is connected with the coil of the time relay.
The feeder of the compressed air lifts via welding machine suspender, and the top of the welding machine is provided with slide rail, the electricity
Air control valve is arranged at the bottom of welding machine suspender, and the welding machine is lifted on the lower section of slide rail, the welding gun by balancer and drag-line
Connected with feeder by tracheae.
The beneficial effects of the utility model：
1. employing new layout structure, and control circuit is introduced, allowed welding machine to possess and automatically cut off compressed air confession
The function of answering, when welding machine is not used more than setting time, time relay automatic control air-valve, compressed air supply is disconnected,
It is changed into automatically controlling manually from original, it is time saving and energy saving；
2. reducing the leakage of compressed air, workshop energy consumption is saved.
Brief description of the drawings
Fig. 1 is positional structure schematic diagram of the utility model in whole welding system；
Fig. 2 is circuit control schematic diagram of the present utility model.
In figure, 1 is electric control valve, and 2 be feeder, and 3 be the time relay, and 4 be auxiliary reclay, and 5 be soldering turret, and 6 are
Slide rail, 7 be balancer, and 8 be drag-line, and 9 be tracheae, and 10 be welding machine suspender, and 11 be shift knob.
Embodiment
Embodiment：Referring to Fig. 1,2.
The utility model discloses a kind of welding machine automatic gas-off device, including an electric control valve 1 and a set of control circuit,
The electric control valve 1 connects with the feeder 2 of compressed air, and the control circuit includes the time relay 3 and middle relay
Device 4, the front end of welding machine are soldering turret 5, and the time relay 3 includes two normally-closed contacts, i.e. KT-1 and KT-2 in Fig. 2, wherein
One normally-closed contact KT-1 connects with electric control valve 1 contact a, b, and another normally-closed contact KT-2 connects with soldering turret switch contact；Institute
State the coil of auxiliary reclay 4 to be connected with the valve contact on welder circuit plate and reset contact, the normally-closed contact of auxiliary reclay 4
Connected with the coil of the time relay 3.In figure, a, b are the switch contact of electric control valve 1, and c, d are dc source contact,
11 be the shift knob of soldering turret 5.
The principle of this case：
The total source of the gas of mash welder is hung, be i.e. increases an electric control valve 1, KT-1, KT-2 difference at feeder 2 in Fig. 1
For the normally-closed contact of the time relay, K1 is the normally-closed contact of auxiliary reclay, exceedes setting value when welding machine time that stops operation
When, i.e., when soldering turret does not work for a long time, the time relay 3 obtains electric, contact KT-1 disconnections, the closing of the dead electricity of electric control valve 1.Work as employee
Start operation, during SR triggering on soldering turret, auxiliary reclay 4 it is electric, contact K1 disconnects control time relay 3 and lost
Electricity, contact KT-1 obtain electric and electric control valve 1 and connected, and compressed air recovers supply, and now welding system starts normal work.
The feeder 2 of the compressed air lifts via welding machine suspender 10, and the top of the welding machine is provided with slide rail 6, institute
The bottom that electric control valve 1 is arranged at welding machine suspender 10 is stated, the welding machine is lifted on the lower section of slide rail by balancer 7 and drag-line 8,
The welding gun is connected with feeder 2 by tracheae 9.Dotted box portion A portions are the easy portion that compressed air leakage occurs in Fig. 2
Point, new layout structure is now employed, and control circuit has been introduced, allow welding machine to possess the work(for automatically cutting off compressed air supply
Can, when welding machine is not used more than setting time, time relay automatic control air-valve, compressed air supply is disconnected, so as to subtract
The leakage of few compressed air, saves workshop energy consumption.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
The equivalents or the direct or indirect technical field for being used in correlation made using the utility model specification and accompanying drawing content,
Similarly it is included in scope of patent protection of the present utility model.
