Description
Technical field
The present invention relates to a kind of arc-welding apparatus that is used for the alternating current-direct current continuous welding, particularly a kind of joint with lower clamp nozzle electric conductor and cable is arranged on not on the lower insulator with the joining lower insulator assembly of handle insulator of handle assembly, the plate spring type welding clamp of handle non-scald on hand when forming that an intercept heat contact fracture belt that conducts and continuous welding between handle assembly and lower insulator assembly.
Background technology
At present, the chucking power of electrode holders clamping welding rod is compressed spring from the steel wire column type of traditional structure mostly both at home and abroad, be that the lower clamp nozzle that is connected with cable on the lower insulator that links of the handle insulator of the upper clamp nozzle of electrode holders control rod assembly and handle assembly is to compress the clamping welding rod with the compression spring, after using a period of time, the welding rod chucking power can obviously weaken along with the elastic fatigue of steel wire column type compressed strong spring, cause the chucking power deficiency of welding rod, directly influence weld job.Meanwhile, on, lower clamp nozzle and welding rod loose contact, also can cause contact resistance to increase, and burn red discard electrode, consequent heat just is transmitted on the handle insulator by lower insulator and cable, in addition, because of the joint of its lower clamp nozzle electric conductor and cable links together by lower insulator and handle insulator, not only heat very directly is transmitted on the handle insulator, and the strong point of compression spring is to the clamping welding rod, distance between the lower clamp nozzle is longer, also increased the length of lower clamp nozzle electric conductor, so this structure also makes the material cost of electric conductor strengthen, handle reaches hot temperature very soon when continuous welding.The improvement that the improvement of the existing electrode holders of cause rests on the draw bail of lower clamp nozzle electric conductor and cable adapter always designs, and this joint always is fixed on the lower insulator that links to each other with the handle insulator, the heat that the joint produces can directly promptly be transmitted on the handle insulator by lower insulator and cable, handle is scalded one's hand, so the problem of handle non-scald on hand can not fundamentally solve the electrode holders continuous welding time.
The inventor once designed laminated type electrode holders (the license notification number is CN100348356C) and Wedge type electrode holder (patent publication No. is CN101306489A) etc. at existing problem spiral, that the presser type electrode holders exist, tried hard to make electrode holders non-scald on hand when the continuous welding operation.Wherein the former laminated type electrode holders are to be upper and lower cable thigh with the share split of electric welding jaw cable, and link into an integrated entity with upper and lower jaw respectively.Its electric welding jaw cable adapter with connect the cable adapter of electric welding machine, utilize wire terminal protection body (iron pipe) to link together, but the cable adapter pressing is difficult to the tight and uniformity of maintenance when practical operation with the forcing press pressing and fixing.Though laminated type electrode holders cable adapter is under the just right situation of stamping press, the contact resistance of joint than spiral, the presser type electrode holders are little, if but stamping press is not in place, the contact resistance of joint increases thereupon, caloric value also just increases, and can form the phenomenon that the handle insulator scalds one's hand equally.If it is good that laminated type electrode holders cable adapter connects, stamping press is selected appropriate, and handle is to be difficult for scalding one's hand, and key is that the stamping press size is difficult to grasp apt.Because be subjected to the restriction of structural factor, the manufacturing cost of laminated type electrode holders also is higher than other electrode holders about 40%.And latter's Wedge type electrode holder comprises control rod assembly, wiring assembly and the handle assembly that fits together, it is cable closely to be pressed on the inclined-plane of lower clamp nozzle electric conductor by the wedge shape briquetting, make the cable adapter extruding closely, strengthen handle problem such as scald one's hand when the continuous welding operation with the contact resistance that tightly do not cause that solves because of joint cable line pressure.Although taked some provision for thermal insulations, because of joint and lower insulator and the handle insulator or the integral structure of its cable and lower clamp nozzle electric conductor, the heat that can't thoroughly cut off the thermal source generation conducts on the handle insulator.
Summary of the invention
The purpose of this invention is to provide a kind of plate spring type welding clamp, the handle insulator of its handle assembly and the lower insulator of lower insulator assembly do not link, between handle assembly and lower insulator assembly, form an intercept heat and contact the fracture belt that conducts, fundamentally solved the hot problem of handle that existing electrode holders continuous welding produces, it is simple in structure, design distributes rationally, not only can reduce manufacturing cost, significant prolongation service life, and really do and accomplish the continuous welding non-scald on hand, improve operating efficiency.
Technical scheme of the present invention is: this plate spring type welding clamp comprises handle assembly and lower insulator assembly, its technical essential is: the lower clamp nozzle electric conductor in the described lower insulator assembly and the joint of cable are arranged on the lower insulator of described lower insulator assembly, and spaced apart does not connect between the handle insulator of described lower insulator and described handle assembly.
Upper insulator in the described handle assembly is provided with coupling spindle, and the lower insulator in the described lower insulator assembly is provided with carriage, and described coupling spindle and described carriage are hinged together.
The coupling spindle that is fixed on the upper insulator of described handle assembly is arranged on and lifts the lifting on the spring support of spring axle having of described upper insulator inwall, and the inboard of the lower insulator of described lower insulator assembly is provided with frame board, is fixed with connection box on described frame board.
In described lower insulator assembly leaf spring is set, and described leaf spring and described connection box and described carriage are mutually permanently connected together, the other end of described leaf spring is connected mutually with the spring axle of lifting that described upper insulator is lifted spring support.
What be arranged on that upper clamp nozzle in the described lower insulator assembly is fixedly connected on described leaf spring lifts the end that the spring axle is connected mutually with described, the electric conductor of described lower clamp nozzle and described leaf spring and described connection box are fixed together, and the relative pincers face of described upper and lower jaw is closely contacted.
The electric conductor of the lower clamp nozzle in the described connection box closely is crimped on by the cable adapter of pressing plate in described lower insulator assembly is set that is arranged on the described frame board.
Advantage of the present invention and positive technique effect are: because the present invention adopts joint with lower clamp nozzle electric conductor and cable to be arranged on not on the lower insulator with the joining lower insulator assembly of handle insulator of handle assembly, between handle assembly and lower insulator assembly, form the special construction that an intercept heat contact fracture belt that conducts, only hinged by the carriage of lifting coupling spindle on the spring support and the lower insulator in the lower insulator assembly of the upper insulator in the handle assembly, except that the hinged place of coupling spindle and carriage, only lifting the spring axle contacts with the joining place of leaf spring, all the other positions do not contact, so the contact area between the two is very little, thereby have internal structure and face shaping advantage all reasonable in design.Therefore, the heat of lower insulator assembly pass to the heat of the upper insulator of handle assembly seldom, these shortages of heat are so that handle insulator temperature is raised to hot degree, so fundamentally solved the hot problem of handle that existing electrode holders continuous welding produces.When continuous welding, although the lower insulator temperature of the lower insulator assembly that is intercepted by fracture belt may reach hot temperature, but when weld job changes welding rod, just handle is pressed to motionless lower insulator, the spring of lifting that leaf spring end that upper clamp nozzle is housed is lifted on the spring support along with upper insulator lifts on axially, and allowing upper and lower jaw open is interchangeable welding rod.Owing to change welding rod and finish, so can't feel hot in moment.Because of the special construction that adopts fracture belt has been to use leaf spring, so great changes will take place for the electrode holders internal structure, jaw, joint, leaf spring close dexterously and combine together, the leaf spring strong point is shortened greatly to the distance between jaw, so the electric conductor length of lower clamp nozzle also shortens thereupon, conductive material than spiral electrode holders saves 2/5, save 3/5～4/5 than the presser type electrode holders, therefore, not only can reduce manufacturing cost, significant prolongation service life, and really do and accomplish the continuous welding non-scald on hand, operating efficiency improved.

The specific embodiment
Describe concrete structure of the present invention in detail according to Fig. 1-9, this plate spring type welding clamp comprises handle assembly and lower insulator assembly.Wherein handle assembly comprises handle insulator 13, instlated tubular 14, aluminium foil thermal resistance reflecting drum 15, upper insulator 12, coupling spindle 7, lifts spring axle 4, lifts spring support 11, aluminium foil thermal resistance reflecting layer 6, screw 9,17, goes up part such as heatproof protective layer 28.The lower insulator assembly comprises upper clamp nozzle 1, leaf spring 5, carriage 8, cable 16, pressing plate 23, lower insulator 20, packing ring 3, screw 2,26,22,21,18, frame board 19, connection box 24, lower clamp nozzle 25, following heatproof protective layer 27 parts such as grade.
The electric conductor of the lower clamp nozzle 25 in the lower insulator assembly of this plate spring type welding clamp and the joint of cable 16 are arranged on the lower insulator of lower insulator assembly 20, and spaced apart does not connect between the handle insulator 13 of lower insulator 20 and handle assembly.The upper insulator 12 that is arranged in the handle assembly is fixed with coupling spindle 7, and the lower insulator 20 that is arranged in the lower insulator assembly is fixed with carriage 8.Carriage 8 and coupling spindle 7 are hinged, make to form an intercept heat between handle assembly and the lower insulator assembly and contact the fracture belt 29 that conducts.The coupling spindle 7 of the upper insulator 12 in the handle assembly is arranged on and lifts the lifting on the spring support 11 of spring axle 4 having of upper insulator inwall.Lifting spring support 11 utilizes screw 9 to be fixed on the inwall of upper insulator 12.Carry out the radiations heat energy conduction in order to intercept heater element to lifting spring support 11, attach aluminium foil thermal resistance reflecting layer 6 in the inboard of lifting spring support 11.Also can coat handle insulator 13 with being arranged on the handle pipe of the upper insulator that links into an integrated entity 12 in the handle assembly and the periphery of instlated tubular 14, and it is spacing fixing to utilize 17 pairs of handle insulators of screw 13 to carry out axial and circumferential, at the handle pipe of upper insulator 12 and instlated tubular 14 aluminium foil thermal resistance reflecting drum 15 is set interior week, to form the multilayer insulation barrier, further strengthen effect of heat insulation to handle.Lifting the coupling spindle 7 on the spring support 11 or lifting spring axle 4 in the handle assembly all is respectively with carriage 8 or leaf spring 5 in point or the line contact lower insulator assembly, therefore contact area is very little, the lower insulator assembly is limited to the heat of handle assembly contact conduction, not enough so that across upper insulator 12, the temperature away from the handle insulator 13 of lower insulator 20 reaches hot degree again.The coupled axle 7 of lower insulator 20 contact conduction heats, to lift that spring axle 4 is transmitted on the upper insulator 12 be very little a part of heat, and the heat of most of contact conduction is blocked by a fracture belt 29 of 12,20 formation of upper and lower insulator.In addition, by instlated tubular 14, aluminium foil thermal resistance reflecting drum 15, aluminium foil thermal resistance reflecting layer 6 has also intercepted the conduction of the heat that the lower insulator assembly produces effectively, makes that in the handle assembly handle insulator 13 temperature do not reach hot degree.For prolonging the service life of electrode holders, the upper and lower heatproof overcoat 28,27 of overfiring-proof is set respectively on the upper and lower insulator 12,20 in the upper and lower jaw outside.
The inboard that is arranged on the lower insulator 20 in the lower insulator assembly utilizes screw 26,21,18 to be fixed with the frame board 19 that matches with lower insulator 20 inner wall shape, and the connection box 24 that is fixed on the frame board 19 utilizes screw 10 fixed with each other the electric conductor of lower clamp nozzle 25 and leaf spring 5 and carriage 8.The structure of the leaf spring 5 of lower insulator assembly both can adopt split type, as employing utilize the structure that screw 10 fixedlys connected with connection box 24 and carriage 8 respectively or adopt with leaf spring 5 directly with make the connection box 24 of one and the structure (not shown) that carriage 8 is fixed together; Also can adopt monoblock type, as adopting leaf spring 5 and connection box 24 are made the structure that one is fixed together with carriage 8 again, or adopt leaf spring 5 and carriage 8 made the structure that one is fixed together with connection box 24 again, or adopt with leaf spring 5 directly and connection box 24 and carriage 8 make the structure (not shown) of one.Present embodiment adopts split-type structural, and promptly the other end of leaf spring 5 is connected mutually with the spring axle 4 of lifting that upper insulator is lifted spring support 11.Upper and lower jaw is set in the lower insulator assembly, upper clamp nozzle 1 be fixedly connected on leaf spring 5 with screw 2, packing ring 3 with lift the ends that spring axle 4 is connected mutually.The electric conductor of lower clamp nozzle 25 and leaf spring 5 are fixed on the connection box 24 of lower insulator assembly, utilize the active force of leaf spring 5 that the relative pincers face of upper and lower jaw 1,20 is closely contacted.Because of leaf spring 5 active forces are big, so electrode carrier keeps steady admittedly, help weld job, also obviously to eliminate simultaneously because of jaw and welding rod loose contact, contact resistance increases the heat that is produced.Because of the lower insulator assembly is suspended on the coupling spindle 7 by carriage 8, so maintain static when carriage 8, depress the upper insulator 12 of handle assembly, lift the leaf spring 5 that 4 drives of spring axle are connected with it and upwards lift, upper and lower jaw 1,25 is opened, so that change welding rod rapidly.In addition, the periphery that is arranged on the upper insulator that links into an integrated entity 12 handle pipes in the handle assembly and instlated tubular 14 coats handle insulator 13, aluminium foil thermal resistance reflecting drum 15 is set in interior week, also intercepted the heat conduction that the lower insulator assembly produces effectively, made that in the handle assembly handle insulator 13 temperature do not reach hot degree.Cable 16 joints that are arranged in the lower insulator assembly closely are crimped on by the electric conductor that is arranged on screw 22 on the frame board 19, the lower clamp nozzle 25 of pressing plate 23 in connection box 24, to reduce contact resistance, reduce caloric value.
When continuous welding, the operator is holding handle insulator 13 and is carrying out weld job, so non-scald on hand during the plate spring type welding clamp continuous welding improves operating efficiency.When changing welding rod, as long as handle insulator 13 is pressed to motionless lower insulator 20, an end that makes the leaf spring 5 that upper clamp nozzle 1 is housed makes upper and lower jaw 1,25 open promptly replaceable welding rod when lifting lifting spring axle 4 and upwards lift on the spring support 11.
