Abstract
The utility model relates to a magnetic suspension type contact device which is particularly suitable for connection of workpiece wirings and workpieces of an electric welder. The central position of the utility model is a magnet which is provided with one layer of insulators on the external contour. The external part of the insulators is a contact plate which is made of conductors. The contact plate is connected with a binding screw and the end face of the contact plate projects out of the end face of the magnet. The utility model realizes good contact between the workpiece wirings and the contact plate and between the contact plate and welded workpieces. The utility model has the advantages of flexible operation, high reliability and good welding quality.
Description
A kind of magnetic force suspending type contactor, what be specially adapted to electric welding machine connects being connected of workpiece alignment and workpiece.
In prior art, the nude that will connect the workpiece alignment end when using electric welding machine partly directly contacts with workpiece, or contacts with workpiece by a conductive plate.This method exists the factor of loose contact.1., make conduction be obstructed and cause the striking difficulty thereby can produce two problems:; 2., in when welding, produce electric arc between workpiece and the wiring part, surface of the work be damaged or scab.For improving its contact condition, the instrument that mechanical rigid clamps has appearred, makes to connect workpiece alignment and workpiece realization excellent contact.But the instrument that this rigidity clamps dismounting is loaded down with trivial details, and is subjected to the restriction of workpiece size, shape, is difficult to use in some occasion.
The purpose of this utility model provides a kind of contactor, overcomes the defective that exists in the prior art, can guarantee to contact with the good of workpiece, uses flexible, easy to operate.
The technical scheme that the utility model adopted: the utility model adopts magnet arrangement, the power that is connected with workpiece as contactor with magnetic force.In the centre of the utility model contactor is magnet, one deck insulator is arranged on the exterior contour of magnet, the outside of insulator is the contact plate that contacts with workpiece, magnet, insulator and contact plate are fixed together, terminal screw is connected with contact plate, contact plate is an electric conductor, and the end face of contact plate protrudes in the end face of magnet.
The nude that connects the workpiece alignment end on the electric welding machine is partly realized excellent contact by terminal screw and contact plate.When work, the end face of contact plate is placed on the welded part, because the effect of magnet makes between contactor and the workpiece and produces attraction, because it is gapped between magnet and the workpiece, contact plate end face around the magnet can be realized contacting well with workpiece, has insulator to separate between magnet and the contact plate.During work, connect workpiece alignment and form path, realize arc welding by contact plate and workpiece.
Because contactor described in the utility model is to utilize magnet suction to realize connecing fixing between workpiece alignment and the welded piece, so use more flexible, general workpiece all can utilize, disassembling section is very convenient, owing to connect between workpiece alignment and contact plate, contact plate and the welded part and all can realize good the contact, so when carrying out weld job, the starting the arc is easy, surface of the work safety can guarantee welding quality.
Magnet described in the utility model can be permanent magnet, also can be electromagnet (if electromagnet need be used excitation supply and circuit thereof, this is a prior art, does not describe in detail).
Fig. 1 is that front view, Fig. 2 are A～A cutaway view.
(1), (5) are contact plate among the figure, are to be made by conductive material.(2), (4) be insulator, make by insulating materials.(3) being magnet, can be permanent magnet, also can be electromagnet, (excitation supply and the circuit thereof of electromagnet omit).(6) being the joint sleeve of contact plate, is to be made by conductive material, and (7) are terminal screw.(8) for connecing the nude part of workpiece alignment.(9) be the workpiece that connects on the electric welding machine
Line contact plate (1), (5) protrude in magnet end face 1～8mm.
Embodiment 2, Fig. 3～Fig. 4 are structural representation, and the section of electromagnet is rounded.
Fig. 3 is a front view, and Fig. 4 is B～B cutaway view.
Among the figure, (11) be contact plate, (12) are insulation board, (13) are magnet (permanent magnet or electromagnet), (14) are terminal screw, (15) are for connecing the workpiece alignment nude partly.Contact plate (11) protrudes in the end face 1～8mm magnet and the insulation board thereof of magnet (13), and the section of contact plate also can be other Any shape.
Claims (4)
1, a kind of magnetic force suspending type contactor, comprise magnet, contact plate and terminal plate is characterized in that, magnet is in the centre of this magnetic force suspending type contactor, one deck insulator is arranged on the outline of magnet, the outside of insulator is a contact plate, and magnet, insulator and contact plate are fixed together, and terminal screw is connected with contact plate, contact plate is an electric conductor, and the end face of contact plate protrudes in the end face of magnet.
