Description

Technical Field

[0001] The utility model relates to the technical field of measuring equipment, and particularly relates to a split balancing body for an altimeter. Background Art

[0002] The probe module of the altimeter needs to move up and down smoothly and freely without any blockage during the movement, and can remain stationary without a locking device at any height. Only when the motor rotates forward and backward, the probe module is driven up and down by a steel belt to measure the workpiece to be measured. Since the probe module itself has a certain self-weight, in order to achieve balance and immobility at any height, a balancing object equal in weight to the probe module needs to be added at the other end of the steel belt to offset the self-weight of the probe module. This kind of balancing object is called a balancing body.

[0003] As Figure 1 shown, during the measurement process of the probe module 300, when the probe module 300 moves to the measured surface, the probe module 300 will suddenly stop. In order to ensure the accuracy and stability of the measurement, the probe module 300 needs to be in a balanced state all the time, so it is required that the balancing body and the probe module 300 must move and stop synchronously. In order to eliminate the influence of its own inertia when the balancing body moves to a stop, it is necessary to tension and connect the head and tail of the probe module 300 and the balancing body around the guide rail column 100 with a transmission belt 400 (steel belt). When the probe module 300 moves, one end of the transmission belt 400 drives the balancing body to move. When the probe module 300 stops, the other end of the transmission belt 400 can prevent the inertial movement of the balancing body.

[0004] The conventional balancing body for counterweight is an iron block, which is rigidly connected when the steel belt is tensioned, resulting in slight deformation of the guide rail column under stress, thus affecting the accuracy. In addition, during the measurement process, the inertial force of the balancing body itself cannot be immediately eliminated when it suddenly stops, so it is transmitted to the probe module, affecting the instability of its measurement value.
