Referring to fig. 1, a steel material dimension measuring mechanism for error compensation based on a standard plane includes a measuring bracket, a reference panel 4 and two reference brackets. The reference panel 4 is supported by two reference supports, and the reference panel 4 can be kept horizontal or inclined.
The measuring support comprises an upper support 2 and a lower support 1, the upper support 2 is T-shaped, the lower support 1 is L-shaped, the upper support 2 and the lower support 1 are vertically arranged, the lower surface of the left transverse part of the upper support 2, the lower surface of the right transverse part of the upper support 2 and the upper surface of the transverse part of the lower support 1 are embedded with measuring probes 3, the measuring end face of each measuring probe 3 is kept horizontal, and the longitudinal part of the upper support 2 is connected with the longitudinal part of the lower support 1.
During actual selection, each measuring probe 3 is a laser displacement sensor, and a laser emitting end and a laser receiving end are arranged on the measuring end face of the laser displacement sensor.
After the longitudinal part of the upper bracket 2 is connected with the longitudinal part of the lower bracket 1, the measuring probe 3 in the left transverse part of the upper bracket 2 is positioned right above the measuring probe 3 in the transverse part of the lower bracket 1, and the measuring probe 3 in the right transverse part of the upper bracket 2 is positioned right above the reference panel 4.
Preferably, the reference support comprises an upper vertical plate 5, a lower vertical plate 6 and two adjusting screws 7, wherein the upper vertical plate 5 is stacked on the lower vertical plate 6 and is connected with the lower vertical plate 6 through the two adjusting screws 7. The distance between the upper vertical plate 5 and the lower vertical plate 6 can be adjusted through the two adjusting screws 7, so that the height of the reference support is changed, and the height of the reference panel 4 is further adjusted. Since the higher the accuracy of the measuring probe 3, the smaller its range, the height of the reference panel 4 has to be adapted to the range of the measuring probe 3 in the right lateral part of the upper carriage 2.
Preferably, the measurement accuracy of the measurement probe 3 in the right lateral portion of the upper frame 2 is greater than the measurement accuracy of the measurement probe 3 in the left lateral portion of the upper frame 2. In the process of measuring the overall dimension of steel by matching the measuring probe 3 in the left transverse part of the upper bracket 2 with the measuring probe 3 in the transverse part of the lower bracket 1, the measuring probe 3 in the right transverse part of the upper bracket 2 is matched with the reference panel 4 to synchronously measure errors, even if the measuring precision of the measuring probe 3 in the left transverse part of the upper bracket 2 is enough, errors cannot be measured, and in view of cost, the measuring precision of the measuring probe 3 in the left transverse part of the upper bracket 2 is not necessarily too high.
Specifically, the error compensation principle of the steel material overall dimension measuring mechanism based on the standard plane for error compensation is as follows:
