Abstract
The utility model discloses a welding bolt locating device which comprises a projection welding bolt and a stamping part. The stamping part is provided with a stamping part hole, the projection welding bolt is composed of a bolt head and a bolt rod, an upper electrode is arranged on the upper portion of the stamping part, and a lower electrode is arranged on the lower portion of the stamping part. The bolt rod of the projection welding bolt penetrates through the stamping part hole and is located between the upper electrode and the lower electrode, a bolt hole is formed in the lower electrode, and an insulation sleeve is embedded in the bolt hole and arranged on the bolt rod of the projection welding bolt in a sleeved mode. Compared with an existing locating device, the welding bolt locating device is simple in structure, bolts are accurately located, the phenomena that the bolt rod is skew to and not perpendicular to a stamping sheet metal part are avoided, welding efficiency is greatly improved compared with arc welding, and damage of the arc welding on the stamping sheet metal part and bolt is also avoided.
Description
Technical field
The utility model relates to a kind of automobile manufacture industry, relates in particular to a kind of weld bolt positioner.
Background technology
At present at automobile manufacturing field, particularly in automobile body manufacture process, relate to bolt welding to punching parts, these bolts will guarantee status requirement when welding on punching parts, must not cause damage to punching press piece surface and bolt shank when welding simultaneously.General way is first in punching parts position to be welded, to pull line or make welding position by ways such as positioning templets at present, by arc welding, bolt is soldered on punching parts again, although this way also can achieve the goal, there is the following deficiency: (1) position to be welded is found trouble, poor accuracy accurately; (2) welding efficiency is low; Arc welding splash greatlyr, need cleaning welding slag to splash, easily cause the damage of punching parts piece surface and bolt.
In driver's cabin is produced, often need to be on punching press sheet metal component weld bolt, when welding, require bolt and punching press sheet metal component hole to align, can not be crooked, while adopting common arc welding, easily there is the damage to bolt shank silk tooth, meanwhile, during arc welding splash and welding deformation easily causes part injury, adopt resistance projection-welding, design a set of bolt convex welding device, just necessitate.
Utility model content
The problem existing for above-mentioned prior art, the utility model object is to provide a kind of location that solved to be forbidden, weld the weld bolt positioner that rate is low, piece surface is easily caused to the problems such as damage that comes into force.
The technical solution of the utility model is: a kind of weld bolt positioner, comprise projection welding bolt, punching parts, on described punching parts, offer punching parts hole, described projection welding bolt is comprised of bolt head and shank of bolt, described punching parts top is provided with top electrode, below is provided with bottom electrode, the shank of bolt of described projection welding bolt is through punching parts hole, and between top electrode and bottom electrode, on described bottom electrode, offer bolt hole, described bolt hole is embedded with insulation sleeve, and described insulation sleeve is set on the shank of bolt of projection welding bolt;
As preferably, the bolt head of described projection welding bolt is provided with projection welding point, and described projection welding point is between bolt head and punching parts;
As preferably, described insulation sleeve and bottom electrode interference fits;
As preferably, described top electrode is connected with the upper electrode arm of mash welder, and described bottom electrode is connected with electric welding machine bottom electrode cantilever.
The beneficial effects of the utility model are: the utility model is simple in structure, accurate to Bolt to position, avoid crooked, the off plumb situation of bolt shank and punching press sheet metal component, weld production efficiency simultaneously and greatly improve compared with arc welding, also avoided the damage of arc welding to punching press sheet metal component, bolt.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
In figure: 1. bottom electrode; 2. insulation sleeve; 3. punching parts; 4. projection welding bolt; 5. top electrode.
The specific embodiment
Embodiment: as a kind of embodiment of the present utility model, a kind of weld bolt positioner as shown in Figure 1, comprise projection welding bolt 4, punching parts 3, on described punching parts 3, offer punching parts 3 holes, described projection welding bolt 4 is comprised of bolt head and shank of bolt, described punching parts 3 tops are provided with top electrode 5, below is provided with bottom electrode 1, the shank of bolt of described projection welding bolt 4 is through punching parts 3 holes, and between top electrode 5 and bottom electrode 1, on described bottom electrode 1, offer bolt hole, described bolt hole is embedded with insulation sleeve 2, described insulation sleeve 2 and bottom electrode 1 interference fits, be difficult for loosening, described insulation sleeve 2 is set on the shank of bolt of projection welding bolt 4, the bolt head of described projection welding bolt 4 is provided with projection welding point, described projection welding point is between bolt head and punching parts 3
Projection welding bolt 4 specifications of welding are big or small as required, the insulation sleeve 2 of design dimension size, utilize interference fits to embed in the bolt hole of bottom electrode 1 insulation sleeve 2, on bottom electrode 1 cantilever that is fixed on common seat formula mash welder of bottom electrode 1, being installed on the top electrode of formula mash welder 5 arm of top electrode 5.While needing projection welding on punching parts 3, the bolt hole that projection welding bolt 4 is passed on punching parts 3, again the shank of bolt of projection welding bolt 4 is partly put into insulation sleeve 2, utilize like this insulation sleeve 2 that shank of bolt is partly fixing, and insulate with bottom electrode 1, during spot welding, the electric current projection welding point that the utmost point 5 passes through on the bolt heads of projection welding bolt 4 from power on contacts with punching parts 3 upper surfaces, then rely on the lower surface of punching parts 3 and the end contact of bottom electrode 1 bottom electrode 1 of flowing through, form closed-loop path, electric current is at the projection welding point of projection welding bolt 4 and the contact position heating and melting shape solder joint of punching parts 3 like this, so just projection welding bolt 4 and punching parts 3 can be welded together.
The utility model is considered the protection to screw thread on the shank of bolt of projection welding bolt 4, avoid electric current when welding to projection welding bolt 4 bar portions, to bottom electrode 1, to form loop through top electrode 5 simultaneously, cause thread damage, the ad hoc insulation sleeve 2 with insulating effect of counting out, can reach like this welding current via top electrode 5 to the salient point on projection welding bolt 4, to punching press sheet metal part, arrive again bottom electrode 1 and form current loop, upper/lower electrode 1 is when welding (pressing) work simultaneously, due to the plane of the upper/lower electrode 1 head pressuring action to weld bolt head plane, avoided the crooked of shank of bolt and punching press sheet metal component.
Above a kind of weld bolt positioner provided by the utility model has been carried out to detailed introduction, applied specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment is just for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, to change of the present utility model and improvement, will be possible, and can not exceed design and the scope of accessory claim defined, in sum, this description should not be construed as restriction of the present utility model.
