Abstract

PROBLEM TO BE SOLVED: To automate the suspending of weights of a torque calibrating device by providing a suspending bar on a calibrating arm so as to have a mechanism for successively stacking weights, providing a collar part on the weight, vertically moving the weight part so that the load on the calibrating arm of the weights can be freely set, and constituting the calibrating arm so that a plurality of weights can be suspended. SOLUTION: A support bar 2a pushes up the collar of a calibrating weight 3 by the pushing-up to L5 of a lift frame 2 by a jack 10. A support bar 2b and a bar 2c also push up a weight 4 and a weight 5, respectively. A suspending bar 1 is also raised, and a space L is kept between a hook and a connecting metal fitting 12, so that the load applied to a calibrating arm 7 is zero. The weight 3 and the weight 4 can keep a space of L2, and the weight 4 and the weight 5 can keep a space L3. When the weight 5 is set on the first stage, L1 is zero while the lift frame 2 is lowered to stop the suspending lowering of the weight, and when the lift frame 2 is further lowered, the composite weight totaled with the weight 5 is added to the bar 2c. The carrying and setting can be easily performed by integrating the weight to the lift frame.

2. Description of the Related Art Torque calibration devices are frequently used for performance tests in the field of development and production of internal combustion engines. Usually, this device is composed of an oscillator and a rotor, and it is possible to measure the reaction force of these and measure the torque by the distance from the rotation center to the measurement site. FIG. 8 shows an engine dynamometer as an example of the torque calibration device. In this figure, an oscillator 13 of the electric dynamometer is swingably supported by a levitation bearing 16 on a bed 17 while a rotor shaft 14 is swingably supported by the oscillator 13. ing. A torque arm 18 is horizontally attached to the rear end of the oscillator 13, and a load cell 19 as a load measuring device is interposed between the tip of the torque arm 18 and the bed 17.

The load cell 19 converts the compression load and the tension load into electrical signals to measure both left and right rotation torques. However, as the tests are repeated, measurement errors gradually occur. Therefore, in order to accurately perform the power performance test, it is necessary to appropriately perform an error check, that is, a calibration. As shown in FIG. 5, when the calibration of the electric dynamometer is performed, a method is employed in which the calibration weight 5 is suspended at the ends of the calibration arms 7 and 7 'on the left and right sides of the oscillator 13. In the illustrated example, the calibration arm 7 on the left side is attached to the oscillator 13.
Generates a counterclockwise rotational force. As a result, the simulated load P in the compression direction acts on the load cell 19, and the measured value is displayed on the display unit 15a of the torque measuring device 15. Calibration is performed by comparing this measured value with the rotational torque (pre-calculated) corresponding to the simulated load P. Further, the calibration is performed by suspending the calibration arm 5 ′ on the pulling side of the load cell 19 and the calibration weight 5 and generating a clockwise rotation force on the oscillator 13.

The method of suspending the calibration weight 5 is shown in FIGS.
It is shown in (c). All of this work is performed manually, and first, the hanging rod 1 is connected to the calibration weight 5 for the lowermost stage.
Next, the hook of the hanging bar 1 is hooked on the connection fitting 12 connected to the calibration arm 5 and is suspended therefrom. The calibration weights are sequentially stacked one by one using the lowermost weight as a stopper, and the stacking and weighting operation is completed up to a simulated load equivalent to the rated torque of the electric dynamometer. Next, the weight-reducing operation is started, and one by one is removed from the stacked uppermost weighing weights, and finally the hook of the hanging bar 1 is removed, and the operation is completed. However, this operation is considerably complicated.

In the above embodiment, the load is sequentially added to the three sets of the calibration weights. However, it is of course possible to remove the load by adopting the reverse procedure. For example, in FIG. 7, when the load on the calibration arm 7 is unloaded from three stages of the calibration weight to two stages, the lift frame 2 is set to L1
While ascending from 1 to L9, the suspended calibration weight 3
The upper surface of the weighing weight 4 is separated from the lower surface of the measuring weight 4 and stops being lifted. The ascending support bar 2a stops ascending with the gap between the calibration weight 3 and L10 being zero. In this state, the weight of the calibration weight 3 is subtracted, and the load can be removed from the calibration arm 7. Further, even when the number of weighing weights is further increased, hanging and unloading of the weighing weights can be similarly performed by providing the corresponding number of support bars.

1. A torque calibration device having an automatic suspension mechanism for suspending a plurality of weights on a calibration arm having one end fixed to an oscillator, wherein a suspension rod is provided on the calibration arm via a connection fitting. The hanging rod has a mechanism in which the weights are sequentially stacked, a flange is provided on the weight, the flange is brought into contact with a support frame, and the vertical weight is given to the weight so that the hanging rod is moved. A lift unit for freely applying a load to the calibration arm through the lift unit, and further provided with lift unit driving means for moving the lift unit up and down, wherein the lift unit is configured to lift the lift unit with respect to at least one suspended weight. And a mechanism for vertically moving so as to be able to arbitrarily change a relative position of the flange portion and each of the weights, and having a mechanism that allows a plurality of weights to be freely hooked to the calibration arm sequentially via the hanging rod. Characterized by Luc calibration equipment.
