Abstract
The utility model discloses a spot welding assisting tool with a positioning hole punching sheet. The spot welding assisting tool comprises a strip-shaped clamping seat, wherein one side face of the strip-shaped clamping seat is provided with a strip-shaped groove; the width of the groove is matched with the width of a narrow side of a ventilation groove plate requiring spot welding; at least one end face of the clamping seat is a horizontal plane, and can be used for supporting the clamping seat which is stably and vertically arranged on the punching sheet; and the groove can be used for clamping the ventilation groove plate. During spot welding, a ventilation groove sheet is clamped into the groove of the spot welding assisting tool and is positioned according to a welding positioning hole, and the tool is placed onto a welding position of the ventilation groove sheet of the punching sheet together with the ventilation groove sheet, so that spot welding operation can be performed. The spot welding assisting tool designed and manufactured in the utility model has the advantages of simple tool structure, easiness, rapidness and convenience for applying, fixed groove sheet, prevention of leftward and rightward inclination phenomenon in the spot welding process of the groove sheet, high safety, and need of pressing the tool with a thumb without holding the groove sheet with a hand after the assembly of the tool.
Description
Technical field
The utility model relates to a kind of workpiece electric welding auxiliary mould, especially relates to the auxiliary mould of a kind of electric machine rotor iron-core lamination band ventilation channel plate structure spot welding.
Background technology
It is among main high pressure, the specific type of electric machine, to adopt ventilation channel plate that the purpose that iron core separates is provided radial ducts, to increase area of dissipation that the motor of stator and rotor cores band ventilation channel plate structure has been widely used in air-cooled.
The making of ventilation channel plate is through mash welder vent segment (or I shape channel-section steel) to be connected with ventilation channel plate punching spot welding, and I shape channel-section steel upper and lower surfaces width is big, and is foundry goods; Spot-welding technology property is good, but because volume is big, has reduced draught area under the equivalent amount; Thereby gradually adopt the thinner vent segment of width to substitute in the design, and the thickness of vent segment is general≤3mm, and vent segment thickness commonly used is 2mm; Be 10mm highly, contact with punching by narrow limit during spot welding.
Because slotted vane is very thin, need the operator firmly just can put surely during spot welding with hand steered, slotted vane can receive the greater impact power of plumb joint in the pinpoint welding procedure; The risk that has certain lodging adds that slotted vane adopts Sheet Metal Forming Technology to be made, and can form certain radian in positive incision after the punching press; This make in the pinpoint welding procedure slotted vane more difficulty put surely; The slotted vane that weldering is come out tilts, and is highly also uneven, causes the part slotted vane not to be forced into after laminating; In case becoming flexible and throwing away at a high speed appears in this slotted vane weld seam in the motor operation course, consequence is hardly imaginable; And slotted vane lodging phenomenon appears when adopting hand directly to buttress spot welding, the meeting adversary causes and weighs wounded, has very big potential safety hazard.
The utility model content
The purpose of the utility model is to overcome above-mentioned defective, particularly to the ventilation channel plate punching that the welding locating hole is arranged, proposes a kind of simple in structurely, uses simple and fast spot welding auxiliary mould easily.
In order to realize above-mentioned utility model purpose; The technical scheme that the utility model adopts is: a kind of spot welding auxiliary mould with the locating hole punching, comprise a strip deck, and a side of said strip deck offers the strip groove; The width of said groove is adaptive with the narrow hem width degree of the ventilation channel plate of wanting spot welding; At least one end face of described deck is a horizontal plane, can support stable being placed in the punching of erectting of deck, and groove can block ventilation channel plate.
As the further improvement of the utility model, said groove is the notch cuttype groove, and the width that the slot-open-section of groove is offered is than the wide 2-3mm of channel bottom, and the degree of depth is 2-4mm, can avoid being stuck in greatly in the groove because of bond pad locations expands to become, and causes frock to take off difficulty.
As the further improvement of the utility model, described deck is a rectangular strip body, and two sides offering the groove adjacent side are provided with the double airfoil type boss, make things convenient for the taking and placing of this frock.
During spot welding, vent segment is snapped in the groove of the utility model,, this frock is placed on together with vent segment on the welding position of punching vent segment, can carry out spot weld operation according to welding locating hole location.
The spot welding auxiliary mould that the utility model designs and produces, tool structure is simple, and it is convenient to use simple and fast; Slotted vane is fixed, and makes not occur the phenomenon that tilts in the slotted vane pinpoint welding procedure, and security is good; Only need to pin frock after frock is loaded onto and get final product, and need not use hand steered slotted vane with thumb.
Description of drawings
Fig. 1 is the structural representation of present embodiment.
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the right view of Fig. 1.
The specific embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is a part of embodiment of the utility model, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Shown in accompanying drawing; A kind of spot welding auxiliary mould with the locating hole punching comprises a strip deck 1, and a side of said strip deck 1 offers strip groove 2; The width of said groove 2 is adaptive with the narrow hem width degree of the ventilation channel plate of wanting spot welding; Described deck 1 at least one end face is a horizontal plane, can support stable being placed in the punching of erectting of deck, and groove can block ventilation channel plate.
As the further improvement of present embodiment, said groove 2 is the notch cuttype groove, and the width that the slot-open-section of groove is offered is than the wide 2-3mm of channel bottom, and the degree of depth is 2-4mm, can avoid being stuck in greatly in the groove because of bond pad locations expands to become, and causes frock to take off difficulty.
As the further improvement of present embodiment, described deck is a rectangular strip body, offers two adjacent sides of groove side surface and is provided with double airfoil type boss 3, makes things convenient for the taking and placing of this frock.
During spot welding, vent segment is snapped in the groove of present embodiment,, this frock is placed on together with vent segment on the welding position of punching vent segment, can carry out spot weld operation according to welding locating hole location.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
