Abstract

The invention provides a variable force application device which can easily change applied mass force. The variable force application device is provided with a mass block (6) which applies mass force on a force-applied object, and a mass block holding housing holding the mass block. The mass block is configured with a weighting block (33). The mass block holding housing is provided with a weighting block driving mechanism. The weighting block driving mechanism drives the weighting block (33) to move between a first position and a second position. On the first position, the weighting block (33) is arranged on the mass block (6) and increases weight of the mass block (6). On the second position, the weighting block (33) leaves the mass block (6), and weight increment on the mass block (6) is relieved.

Description

technical field

[0001] The present invention relates to a variable urging device that applies a predetermined mass force to an urging object such as a spring and can change the applied mass force. Background technique

[0002] There is a force applying device. For example, in order to measure the workpiece, a mass block with a predicted quality is pressed on the workpiece (the object to be applied) to apply a certain mass force to the object to be measured, simulate the working conditions, and then measure its correlation. Size, so as to realize the measurement (detection) of the workpiece. For the simulation of different working conditions, different mass forces need to be applied. However, the mass block is usually installed in the mechanism in a specific way, and it is difficult to replace it, that is, there is a problem that it is difficult to change the mass force. Contents of the invention

[0003] In view of this, an object of the present invention is to provide a ...
