Abstract
The utility model relates to an exchange mechanism for an automobile body-in-white welding jig. The exchange mechanism for the automobile body-in-white welding jig comprises square positioning blocks, bayonets, fulcrum pins and springs, wherein clamping grooves used for limiting movement of a workpiece, and clamping grooves used for placing the bayonets are formed in the square positioning blocks, the springs are installed on the bottom faces of the bayonets, and the bayonets are fixed on the square positioning blocks through the fulcrum pins. Compared with the prior art, the exchange mechanism for the automobile body-in-white welding jig has the advantages of being simple in structure, convenient to use, reliable in performance, wide in application range, low in cost and the like.
Description
Technical field
The utility model relates to a kind of exchange mechanism, especially relates to a kind of exchange mechanism for the automobile body-in-white weld jig.
Background technology
At present, on the streamline of weld car, need the body in white of welding different automobile types, for fixing different mechanical devices, need to use different trays and briquetting on the streamline.Therefore, a lot of occasions need to adopt the mechanism of parts exchange, and prevailing exchange mechanism adopts pin and bolt exactly.As shown in Figure 1, workpiece 1 (being tradable parts) is by alignment pin 2 location, by clamping screw 3 lockings.The effect of pin is located exactly, and the effect of bolt is locked exactly.If adopt this mode to exchange parts, in the time of workman's operation, at first he wants tool using, and his workload can be very large.With pin removal alignment pin is pulled out first, then unclamped bolt, change part, be loaded on new part, with the alignment pin location, be tightened by bolts again.Manual work unavoidably can go wrong, and workload is large like this, and efficient is low.
Summary of the invention
The purpose of this utility model is exactly a kind of simple in structure, easy to use, dependable performance is provided in order to overcome the defective that above-mentioned prior art exists, is widely used the exchange mechanism that is used for the automobile body-in-white weld jig with low cost.
The purpose of this utility model can be achieved through the following technical solutions: a kind of exchange mechanism for the automobile body-in-white weld jig, it is characterized in that, this mechanism comprises square locating piece, bayonet socket, fulcrum pin and spring, described square locating piece is provided with the draw-in groove of restriction workpiece motion s and places the draw-in groove of bayonet socket, described spring fitting is on the bayonet socket bottom surface, and described bayonet socket is fixed on the square locating piece by fulcrum pin.
Described bayonet socket one end is provided with the fixture block that the restriction workpiece moves forward and backward, and bayonet socket other end bottom arranges spring.
Described workpiece is provided with the groove that is complementary with fixture block, presses pressing spring, and fixture block is upspring, and changes workpiece, and trip spring is located in the groove of fixture block insertion workpiece.
Described workpiece is that the streamline of weld car under different situations needs the backing pressure piece that exchanges.
Compared with prior art, the utlity model has following advantage:
1, this mechanism scope of application is wide, and is all applicable in any occasion of automobile body-in-white welding field.
2, the use of this mechanism can reduce the workload of workman's operation greatly.Not under the prerequisite of tool using, finish the exchange of part the workman.
3, the use of this mechanism can reduce the cost of automobile production manufacturer greatly.
