Abstract
The utility model relates to a three-pole double-throw switch for an electric welding machine, which is composed of a base, a handle, a knife switch, six static wafer groups fixed on the base and a shifting lever, wherein the handle is fixed on one end of the shifting lever, and the V-shaped knife switch is movably connected with a clamping board of the knife switch and is driven by an insulated driving member which penetrates on the shifting lever; the six static wafer groups are divided into two rows and are respectively arranged on both sides of the shifting lever. The utility model has the characteristics of large contact area, large current flow, convenient operation, safety, easy control, etc., and is especially suitable for switching the AC and the DC power supply of an AC and DC dual-purpose electric welding machine.
Description
The utility model relates to a kind of special welding machine switch, specifically refers to a kind of AC/DC triple-pole double throw electric welding machine switch.
At present, what generally use all is the guillotine type switch, and outside segment conductor was exposed to, fail safe was relatively poor, and can only unidirectionally use, and can't satisfy the AC/DC electric welding machine.
The purpose of this utility model is to provide a kind of safe, reliable, easy to use AC/DC triple-pole double throw electric welding machine switch, and this construction of switch compactness, small and exquisite has kept advantages such as guillotine type switch contact area is big, the magnitude of current is big.
The purpose of this utility model takes following measure to realize: the utility model triple-pole double throw electric welding machine switch comprises pedestal, plug-in strip, handle, is arranged on the static contact group on the pedestal, and driving lever is set on the pedestal, and an end of driving lever is provided with handle; Plug-in strip is designed to " V " font structure, and the V-shaped brake cutter is movably connected on the plug-in strip clamping plate, and is driven by the insulation driving member that is through on the driving lever; Static contact component two rows are separately positioned on the both sides of driving lever.The pedestal reverse side is provided with the terminal block with static contact group, the riveted joint of plug-in strip clamping plate.Rotation with handle, driving lever is stirred the insulation driving member, thereby driving the V-shaped brake cutter is that the center rotates to an angle to flexibly connect axle: three the V-shaped brake cutter or with pedestal on three direct current static contact groups closures of row turn-on powers, or exchange the closed turn-on power of static contact group with three of another row, thereby realize the purpose that the utility model alternating current-direct current exchanges.
Embodiment elaborates to the utility model below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is that the A of Fig. 1 is to schematic diagram
Fig. 3 is the syndeton schematic diagram of V-shaped brake cutter of the present utility model
Among the figure: 1. pedestal 2.V shape plug-in strip 3. static contact groups 4. spring clips 5. handles 6. insulation driving members 7. driving levers 8. supports 9. terminal blocks 10. plug-in strip clamping plate 11. flexibly connect axle
According to Fig. 1-embodiment shown in Figure 3: the utility model triple-pole double throw electric welding machine switch comprises pedestal 1, V-shaped brake cutter 2, static contact group 3, driving lever 7 and rotary handle 5.Static contact group 3 is provided with six, is divided into two rows and is fixed on the pedestal 1 of driving lever 7 both sides, and the lower end of six static contact groups 3 is provided with six terminal blocks 9 respectively.The static contact two sides of each static contact group 3 are respectively arranged with spring clip 4, the contact pressure when closing with assurance V-shaped brake cutter 2.The two ends of driving lever 7 are fixed on the pedestal 1 by support 8, driving lever 7 be arranged to "
" the shape structure.Driving lever 7 passes three insulation driving members 6, the two ends and V-shaped brake cutter 2 riveteds of insulation driving member 6.V-shaped brake cutter 2 flexibly connects with plug-in strip clamping plate 10.Plug-in strip clamping plate 10 are fixing with pedestal 1, and its lower end and terminal block 9 riveteds are fixed, and promptly three pass through plug-in strip clamping plate 10 and three terminal blocks 9 connections to the V-shaped brake cutter.
When handle 5 rotated to an angle, driving lever 7 was stirred three insulation driving members 6 simultaneously, and drive three rotates to an angle V-shaped brake cutter 2 with flexibly connecting axle 11, thereby reached the purpose of Switching power.Promptly with the rotation of driving lever 7, be arranged in parallel three V-shaped brake cutter 2 respectively with three static contact group 3 closures of a row of the confession DC power supply of driving lever 7 one sides or arrange three static contact group 3 closures with one of confession the AC power of driving lever 7 opposite sides respectively, thereby conducting direct current or AC power.
Structural design of the present utility model compared with prior art has outstanding advantage: adopt With " V " shape lock cutter, more easily realize AC-DC conversion for the AC/DC electric welding machine; Adopt The structural principle of guillotine type switch and designing, the contact area is big, the magnitude of current is big; Novel structure, Compact; Easy to operate, safe and reliable, easy to control.
