Description

A kind of used for positioning weldment

Technical field

The utility model is related to spot welding manufacture field, more particularly to a kind of used for positioning weldment.

Background technology

Mash welder system uses the principle of double-sided double-point over-current welding, and two electrodes pressurization workpiece make double layer of metal exist during work Form certain contact resistance under the pressure of two electrodes, and welding current from an electrode flow through another electrode when in two contact resistances Point forms the thermal welding of moment, and welding current moment flow to this electrode forming circuit, and not from another electrode along two workpiece The internal structure of welded piece can be injured；When carrying out spot welding to workpiece, it usually needs stent props up workpiece to be welded Support.

Existing to can refer to the Chinese patent that Authorization Notice No. is CN204308457U, it discloses a kind of suspension type multiple spots Welder, including stent, guide assembly and welding gun, cradle top setting is for the frame of guide assembly movement, guide assembly edge The transverse shifting guide rail of frame movement and the longitudinal movement rail composition welding gun being arranged on transverse shifting guide rail are connected to vertical To the lower part of moving guide rail, grip part is equipped on welding gun.

But in the prior art, when welding sheet metal component such as air conditioner cover when frivolous plank, since the position of mash welder is solid It is fixed, need manually to move workpiece to be welded to realize spot welding, since manual operation has an error, butt welding point spacing it is uniform Property is held inaccurate, therefore it is asking of solving of a needs that how the position of tack weld, which makes the spacing of each solder joint identical, Topic.

Utility model content

The purpose of this utility model is to provide a kind of used for positioning weldment, has the position of enough tack welds so that weldering The advantages of spacing of point is identical.

The above-mentioned technical purpose of the utility model technical scheme is that：

A kind of used for positioning weldment is connected to the sliding rack of fixed frame including fixed frame, sliding, and described weldment is also Including the positioning device being set in sliding rack, the positioning device includes the positioning component being set in sliding rack and is fixedly arranged on Determine the sliding component on frame；The positioning component include sliding be connected to the locating rod of sliding component, one end be set on it is in locating rod and another One end is fixedly connected on the fixed link of sliding rack, the vertical straight slot being opened in locating rod, the retaining spring in straight slot, supports It is connected to retaining spring both ends and is connected in the steel ball at straight slot both ends and multiple is opened on sliding component and the card of spaced set Access slot, the diameter at the straight slot both ends are less than the diameter of steel ball, in the steel ball link slot.

By using said program, mobile sliding rack makes it slide on fixed frame, and during movement, locating rod is in cunning It moves in part and slides, the retaining spring in locating rod is in compressive state at this time, and when sliding onto in buckling groove, retaining spring resets And make in steel ball link slot, it realizes the effect of positioning, spot welding is carried out to workpiece to be welded by mash welder at this time, then Sliding rack is continued to move to, retaining spring is compressed, and when it is moved again to buckling groove, steel ball is real again in link slot The effect now positioned, since the spacing of buckling groove is all identical, it can be ensured that the spacing of solder joint is identical every time, due to logical The diameter at the both ends of slot is less than the diameter of steel ball, so steel ball is without departing from straight slot.

Preferably, one end clamping of the locating rod far from fixed link is equipped with sliding pearl, the sliding component is perpendicular to clamping The side of slot offers the slippage slot for sliding pearl horizontal sliding.

By using said program, during locating rod moves, the sliding pearl in locating rod can be in slippage slot Sliding makes it slide for laborsaving.

Preferably, the sliding rack includes two grip blocks for being parallel to sliding component, the bottom of the grip block, which is equipped with, to be slided Wheel, the fixed frame are equipped with sliding rail, and the pulley sliding is in sliding rail.

By using said program, sliding rack is slided by pulley in sliding rail, for laborsaving, when the position of sliding rail is fixed When, the movement locus of sliding rack can be consistent with sliding rail always so that the position of all solder joints remains one directly Line.

Preferably, the sliding rail madial wall is equipped with rubber pad with pulley contact faces.

By using said program, sliding rail madial wall is equipped with rubber pad with pulley contact faces, can reduce pulley and sliding rail The noise that the friction and reduction pulley generated during contact generates during movement.

Preferably, the sliding rack further includes two horizontal verticals in the sliding extension bar of grip block, sliding extension bar packet Include the sliding bar for being vertically located in grip block and the sliding sleeve for being vertically located in another grip block, the sliding bar Sliding sleeve is plugged in, the sliding sleeve, which is detachably fixed, is connected to sliding bar.

By using said program, by adjusting the spacing of sliding bar and sliding sleeve, so as to adjust two grip blocks it Between spacing, when the position of sliding bar and sliding sleeve is fixed, tighten slide bolt, be that sliding bar is fixed with sliding sleeve, So as to fix the spacing between two grip blocks.

Preferably, the inner surface of the grip block offers the holding tank being adapted with the thickness of workpiece to be welded.

By using said program, holding tank that the inner surface of grip block offers can more securely clamp to be welded The workpiece connect.

Preferably, the fixed link is equipped with fixed spring, the fixed link and fixed spring close to one end of locating rod It is plugged in locating rod.

By using said program, when by grip block, when tuning up, fixed link is moved therewith to the direction of its adjacent positioned bar It is dynamic, at this point, the fixed spring between fixed link and locating rod is compressed so that locating rod is slid always in sliding component, and steel Pearl in link slot and can will not shift, and when the spacing of grip block becomes small, fixed link is therewith to adjacent far from its The orientation movement of locating rod, when clamping plate spacing minimum, fixed spring is nature, will not generate drawing force to locating rod.

Preferably, slip hand lever is installed on the grip block.

By using said program, hand lever is slided by mobile, sliding rack can be driven to move, so as to avoid operator Member is in direct contact with sliding rack, the possibility of dangerous generation is reduced, for safety.

In conclusion the utility model has the advantages that：

1. by being used cooperatively for equidistant buckling groove and steel ball, the intermittent movement of sliding rack can be realized, and protect The spacing demonstrate,proved between each solder joint is identical so that it is beautiful that weldment completes effect；Sliding pearl in locating rod can be in slippage slot Sliding, it is convenient and strength-saving；The fixed spring being equipped between locating rod and fixed link can ensure locating rod always in link slot And it does not shift；

2. the pulley that the lower end of grip block is equipped with can slide in sliding rail, convenient and strength-saving；The fixation of sled position makes cunning It moves frame and remains linear motion, can guarantee the position of all solder joints always in straight line；What the madial wall of sliding rail was equipped with Rubber pad can reduce friction during pulley sliding；
