The forging industry usually requires high installation accuracy, and the control error needs to be within 0.1mm. The commonly used methods have certain problems. For example, using a theodolite to measure verticality cannot meet the accuracy requirements, and using a frame level to measure horizontality is inefficient. Utility Model Content

[0019] A linear measurement tool, such as Figure 1-7 As shown, it includes an end cap 4 and a base 1 that fit together. A cylindrical insulating sleeve 2 fits between the end cap 4 and the base 1. A power supply 7 is installed inside the insulating sleeve 2. A micrometer side head 5 is provided on the end cap 4. A through hole is opened on the outer wall of the insulating sleeve 2, and an indicator light 6 is installed inside the through hole. The positive terminal of the power supply 7 is connected to the positive terminal of the indicator light 6, the negative terminal of the indicator light 6 is connected to the end cap 4, and the negative terminal of the power supply 7 is connected to the base 1.
[0020] Screws 8 that mate with insulating sleeve 2 are evenly distributed on end cap 4 and base 1; end cap 4 and base 1 have the same shape; micrometer side head 5 is located at the center of end cap 4; end cap 4 and base 1 are both metal parts; the flatness of the lower surface of base 1 does not exceed 0.01mm; power supply 7 is connected to indicator light 6 and base 1 through wire 3, and indicator light 6 is connected to end cap 4 through wire 3; power supply 7 is fixed inside insulating sleeve 2.
[0021] The positive terminal of power supply 7 is connected to the positive terminal of indicator light 6, the negative terminal of indicator light 6 is connected to end cover 4, and the negative terminal of power supply 7 is connected to base 1. During measurement, the part being measured, the plumb bob or steel wire rope, and in this embodiment, together form a closed circuit, and indicator light 6 lights up.
[0022] During the perpendicularity measurement of the part being tested, the base 1 of this embodiment is placed firmly against the surface being tested, and the micrometer side head 5 is gradually adjusted until it contacts the magnetic plumb line wire rope. The indicator light 6 lights up, and the measurement data is read and recorded. The same steps are repeated to measure multiple points along the vertical direction, calculate the relative value, and obtain the perpendicularity of the part being tested.
[0023] The principle of levelness measurement is the same as that of verticality measurement. During the measurement process, the upper surfaces of the two equal height blocks should be in the same plane, the steel wire rope should be taut and horizontal, and the levelness of the measured part should be obtained.
