Description
Technical field
The present invention 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 to react this mechanism in the fluctuation of 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.The load strength that also there is no at present a kind 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.
Summary of the invention
Technical matters to be solved by this invention 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.
Technical scheme of the present invention 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 for the draw-in groove of 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 in this end, connect counterweight, 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 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, and every a slice comprises rhabodoid and the head coordinating 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 the place, four angles of pedestal is respectively equipped with a bolt mounting holes.
This kind of fixture load force measurement mechanism with said structure is fixed in the same plane of fixture by fixture load force measurement mechanism, by the hanging strength of counterweight, weigh the side-play amount of clamp mechanism, 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 invention will be further described:
Fig. 1 is structural representation of the present invention.
Fig. 2 is the fit structure schematic diagram of middle pulley lever of the present invention 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 be the present invention for the structural representation of the method measurement mechanism of measured material load force, Fig. 2 is the fit structure schematic diagram of middle pulley lever of the present invention 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 the place, four angles 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 for the draw-in groove of 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 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.
Utilize the method that above-mentioned measurement mechanism detects to be: 1) pedestal of measurement mechanism 1 to be bolted on surface level;
2) height of adjustable pulley lever 3, make pulley lever 3 with clamp mechanism to be detected when same level line, pulley lever is interior fixing at guide rail 4;
3) by one end of lifting rope 6 through pulley 5, and connect counterweight 7 in this end, the suspension ring 8 of the other end of lifting rope 6 are fixed on band and detect on the position that clamp mechanism need to measure;
4) by the unbalance loading amount of portable three-coordinate measured material mechanism, then the data that this measured value and fixture to be measured do not stress under state are contrasted, must deviate.
When described deviate is within the scope of ± 0.2mm, it is qualified to be considered as, and when described deviate exceeds this scope, is considered as defective.As long as clamp mechanism side-play amount, in specialized range, just can guarantee the stability of clamp mechanism, guarantee that fixture load force meets performance request for utilization, 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.
