One end of the pulley lever is fixed to the guiding rails, the guiding rails are evenly distributed from top to bottom in sequence in the length direction of the upright, the pulley lever is fixed to the inner portion of the guiding rails through bolts, a plurality of clamping grooves used for fixing the pulley lever are formed in the guiding rails, one end of the pulley lever is fixed in the clamping grooves of the guiding rails, the other end of the pulley lever is provided with a pulley, one end of a hanging rope penetrates through the pulley and is connected with a weight and the other end of the hanging rope is provided with a hanging ring. The device for measuring the carrying capacity of the clamp and the clamp are fixed to the same plane, the offset of a clamp mechanism is measured through the suspending hanging force of the weight, according to the change of measured data before force receiving of the clamp and after the force receiving of the clamp, whether the carrying capacity of the clamp is qualified or not is judged through a three-coordinate measuring instrument, and influence, caused by the fluctuation quantity of the clamp in the force receiving state, on the size of an automobile body is avoided.

Description

A kind of clamped load force measuring device
Technical field
The present invention relates to a kind of clamped load force measuring device.
Background technology
In auto manufacturing's jig Design manufacture process, the carrying of fixture is to react this mechanism to be subject to for a long time The fluctuation of fixture location dimension in the case of power, confirms only by empirical evaluation to the mechanism load power of fixture, past Toward not reacting time of day very accurately.There is presently no the load strength of a kind of short-cut method measured material, The carrying of fixture cannot be judged in fixture debugging and frock are paid soon, producing in batches to the later stage In journey, the stability of fixture leaves great hidden danger, directly affects the service life of fixture.
Summary of the invention
The technical problem to be solved is to provide a kind of fixture to bear for problems of the prior art Carry force measuring device, its objective is measured material carrying, it is judged that whether the carrying that clamp mechanism bears closes Lattice, it is to avoid the fixture undulate quantity under the stress impact on body dimensions.
The technical scheme is that this kind of clamped load force measuring device includes pedestal and vertical with pedestal pacify The column of dress, described column is provided with the guide rail for fixed block lever, and one end of pulley lever is fixed Guide rail on guide rail and described is provided with several draw-in grooves for fixed block lever, pulley lever One end is fixed in the draw-in groove on guide rail, and the other end is provided with pulley, one end of lifting rope pass pulley, and This end connects counterweight, and 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 the most recessed, protrudes simultaneously, described One end of coordinating with guide rail of pulley lever be provided with elastic card, elastic card is provided with and zigzag knot on guide rail The head that structure coordinates, pulley lever moves on guide rail, and is coordinated with the zigzag on guide rail by elastic card Fixing.
The described elastic card on pulley lever has two groups, and each group has two panels, the most a piece of includes rhabodoid And the head coordinated with zigzag, when pulley lever moves, the head of elastic card is by jagged protrusion Portion extrudes, and rhabodoid shrinks, it is ensured that the head of elastic card slips into next group groove.
Described pedestal welds together with column, and is respectively equipped with a bolt installation at four angles of pedestal Hole.
This kind of clamped load force measuring device with said structure is fixed on by clamped load force measuring device In the approximately the same plane of fixture, weighed the side-play amount of clamp mechanism by the hanging strength of counterweight, then by three To the measurement data change before and after fixture stress, coordinate judges that clamped load power is the most qualified, it is to avoid fixture is being subject to The impact on body dimensions of the undulate quantity under power state;And, whole device is exquisite, simple to operation, Advantage of lower cost.
Accompanying drawing explanation
The invention will be further described below in conjunction with the accompanying drawings:

Detailed description of the invention
Fig. 1 is the present invention structural representation of measurement apparatus, Fig. 2 in the method for measured material carrying Fit structure schematic diagram for middle pulley lever of the present invention Yu guide rail.Combined from structure shown in Fig. 1-2, This kind of clamped load force measuring device includes pedestal 1 and column vertically arranged with pedestal 12, pedestal 1 with Column 2 welds together, and is respectively equipped with a bolt mounting holes at four angles of pedestal 1.Described is vertical Post 2 is provided with the guide rail 4 for fixed block lever 3, and 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 Being fixed in the draw-in groove on guide rail 4, the other end is provided with pulley 5, and one end of lifting rope 6 passes pulley 5, and Connect counterweight 7 in this end, 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 the most recessed, protrudes simultaneously, described cunning One end that turbine/lever 3 coordinates with guide rail 4 is provided with elastic card 9, and elastic card 9 is provided with and the sawtooth on guide rail 4 The head of shape respective outer side edges, pulley lever 3 moves on guide rail 4, and by elastic card 9 and guide rail 4 Zigzag coordinate fixing.
The described elastic card 9 on pulley lever 3 has two groups, and each group has two panels, the most a piece of includes bar Shape body 10 and the head coordinated with zigzag, when pulley lever 3 moves, the head of elastic card 9 is sawed The protuberance extruding of dentation, rhabodoid 10 shrinks, it is ensured that the head of elastic card 9 slips into next group groove.
The method utilizing above-mentioned measurement apparatus to carry out detecting is: 1) that the pedestal 1 of measurement apparatus is solid by bolt Determine in the horizontal plane;
2) height of adjustable pulley lever 3, makes pulley lever 3 and clamp mechanism to be detected be in same water During horizontal line, pulley lever is fixed in guide rail 4;
3) by one end of lifting rope 6 through pulley 5, and counterweight 7, the other end of lifting rope 6 are connected in this end Suspension ring 8 be fixed on band detection clamp mechanism need measure position on;
4) the unbalance loading amount of use portable three-coordinate measured material mechanism, then by this measured value with fixture to be measured not Data under stress contrast, and must deviate.
When in the range of described deviation value is at ± 0.2mm, it is qualified to be considered as, when described deviation value is beyond this model When enclosing, it is considered as defective.As long as clamp mechanism side-play amount is in prescribed limit, it is ensured that clamp mechanism Stability, it is ensured that clamped load power meets performance and uses requirement, it is to avoid fixture undulate quantity under stress Impact on body dimensions.And, whole device is exquisite, simple to operation, advantage of lower cost.
