Abstract
The invention discloses a method for measuring the loading capacity of a clamp mechanism. The method comprises that 1) a pedestal of a detector is fixed on the horizontal surface via bolts; 2) the height of a pulley lever is adjusted, so that the pulley lever is fixed in an access when the pulley lever and the to-be-measured clamp mechanism are positioned in the same horizontal line; 3) one end of a lifting rope penetrates through a pulley and is connected with a counterweight, and a suspension ring at the other end of the lifting rope is fixed on a portion, which needs to be measured, of the to-be-measured clamp mechanism; and 4) the offset load amount of the clamp mechanism is measured by a portable three-dimensional measuring instrument, and a measured value is compared with data of the to-be-measured clamp mechanism under the unstrained state to obtain a deviation. According to the method, the loading capacity measuring devices are fixed at the same plane of a clamp, the offset amount of the clamp mechanism is measured by utilizing the suspension force of the counterweight, change of measurement data before and after the clamp bears a force is obtained by the three-dimensional measuring instrument, and whether the loading capacity is qualified is determined; and thus, influence on the vehicle body size due to fluctuation of the clamp under the strained condition is avoided.
Description
Technical field
The present invention relates to a kind of method for measured material mechanism load force.
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 method for measured material mechanism load force 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.
To be this kind comprise for the method for measured material mechanism load force technical scheme of the present invention:
1) pedestal of pick-up unit is bolted on surface level; Described pick-up unit comprise pedestal and with the vertically arranged column of pedestal, described column is provided with the adjusting hole for fixed block lever, one end of pulley lever is fixed in adjusting hole, 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.
2) height of adjustable pulley lever, makes pulley lever and clamp mechanism to be detected when same level line, and pulley lever is fixing in adjusting hole;
3) by one end of lifting rope through pulley, and connect counterweight in this end, the suspension ring of the other end of lifting rope 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.
Described adjusting hole has several, and is from top to bottom uniformly distributed successively along the length direction of column, and pulley lever is bolted in adjusting hole.
Described pedestal and column weld together, and the place, four angles of pedestal is respectively equipped with a bolt mounting holes.
This kind with said structure is fixed on the same plane of fixture for the method for measured material mechanism load force 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 the structural representation of pick-up unit in the present invention.
In Fig. 1,1: pedestal; 2: column; 3: pulley lever; 4: adjusting hole; 5: pulley; 6: lifting rope; 7: counterweight; 8: suspension ring.
Embodiment
Fig. 1 is that the present invention is for the structural representation of the method pick-up unit of measured material mechanism load force.Structure is known as shown in Figure 1, and this kind for the method for measured material mechanism load force is: 1) pedestal of pick-up unit 1 is bolted on to surface level; For the pick-up unit of measured material mechanism load force 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 adjusting hole 4 for fixed block lever 3, one end of pulley lever 3 is fixed in adjusting hole 4, and the other end is provided with pulley 5, and one end of lifting rope 6 is through pulley 5, and in this end, connect counterweight 7, the other end of lifting rope 6 is provided with suspension ring 8.Adjusting hole 4 has several, and is from top to bottom uniformly distributed successively along the length direction of column 2, and pulley lever 3 is bolted in adjusting hole 4.
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 in adjusting hole 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.
