Description
Technical field
The utility model relates to a kind of fixture load force measurement mechanism.
Background technology
In auto manufacturing's jig Design manufacture process, the load force of fixture is the fluctuation of this mechanism of reaction in long-term stressing conditions lower clamp location dimension, and mechanism's load force of fixture is confirmed to only depend on experience assessment, often can not react very accurately time of day.Also there is no at present a kind of load strength of short-cut method measured material, in fixture debugging and frock payment, cannot judge soon the load force of fixture, leave great hidden danger to later stage stability of fixture in batch production process, directly affect the serviceable life of fixture.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of fixture load force measurement mechanism for problems of the prior art, its objective is measured material load force, judge that whether the load force that clamp mechanism bears is qualified, avoid the impact of the undulate quantity of fixture under stress on body dimensions.
The technical solution of the utility model be this kind of fixture load force measurement mechanism comprise pedestal and with the vertically arranged column of pedestal, described column is provided with the guide rail for fixed block lever, one end of pulley lever is fixed on guide rail, and described guide rail is provided with several draw-in grooves for fixed block lever, one end of pulley lever is fixed in the draw-in groove on guide rail, the other end is provided with pulley, one end of lifting rope is through pulley, and connect counterweight in this end, the other end of lifting rope is provided with suspension ring.
The both sides of described guide rail are zigzag, and the sawtooth of both sides is simultaneously recessed, protrude simultaneously, one end that described pulley lever coordinates with guide rail is provided with elastic card, elastic card is provided with the head coordinating with the laciniation on guide rail, pulley lever moves on guide rail, and is fixed by the zigzag on elastic card and guide rail.
Elastic card on described pulley lever has two groups, and each group has two, the head that every a slice comprises rhabodoid and coordinates with zigzag, when pulley lever moves, the head of elastic card is subject to jagged protuberance extruding, and rhabodoid shrinks, and guarantees that the head of elastic card slips into next group groove.
Described pedestal and column weld together, and four angles place of pedestal is respectively equipped with a bolt mounting holes.
This kind of fixture load force measurement mechanism with said structure is fixed on by fixture load force measurement mechanism in the same plane of fixture, weigh the side-play amount of clamp mechanism by the hanging strength of counterweight, by three-dimensional, the measurement data of the stressed front and back of fixture is changed and judges that whether fixture load force is qualified again, avoid the impact of the undulate quantity of fixture under stress on body dimensions; And whole device is exquisite, simple to operation, cost is relatively low.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the fit structure schematic diagram of the utility model middle pulley lever and guide rail.
In Fig. 1-2,1: pedestal; 2: column; 3: pulley lever; 4: guide rail; 5: pulley; 6: lifting rope; 7: counterweight; 8: suspension ring; 9: elastic card; 10: rhabodoid.
Embodiment
Fig. 1 is the structural representation of the utility model for the method measurement mechanism of measured material load force, and Fig. 2 is the fit structure schematic diagram of the utility model middle pulley lever and guide rail.From structure shown in Fig. 1-2 in conjunction with, this kind of fixture load force measurement mechanism comprise pedestal 1 and with the vertically arranged column 2 of pedestal 1, pedestal 1 welds together with column 2, and four angles place of pedestal 1 is respectively equipped with a bolt mounting holes.Described column 2 is provided with the guide rail 4 for fixed block lever 3, one end of pulley lever 3 is fixed on guide rail 4, and described guide rail 4 is provided with several draw-in grooves for fixed block lever 3, one end of pulley lever 3 is fixed in the draw-in groove on guide rail 4, the other end is provided with pulley 5, one end of lifting rope 6 is through pulley 5, and at this end connection counterweight 7, the other end of lifting rope 6 is provided with suspension ring 8.
The both sides of guide rail 4 are zigzag, and the sawtooth of both sides is simultaneously recessed, protrude simultaneously, one end that described pulley lever 3 coordinates with guide rail 4 is provided with elastic card 9, elastic card 9 is provided with the head coordinating with the laciniation on guide rail 4, pulley lever 3 moves on guide rail 4, and is fixed by elastic card 9 and the zigzag on guide rail 4.
Elastic card 9 on described pulley lever 3 has two groups, each group has two, the head that every a slice comprises rhabodoid 10 and coordinates with zigzag, when pulley lever 3 moves, the head of elastic card 9 is subject to jagged protuberance extruding, rhabodoid 10 shrinks, and guarantees that the head of elastic card 9 slips into next group groove.
Utilize the method that above-mentioned measurement mechanism detects to be: 1) pedestal of measurement mechanism 1 to be bolted on surface level;
