The fixed claw described in the technical solution is made of bent rectangular steel plate, and a circular through hole is processed at the bottom thereof.

The connection plate described in the technical proposal is a part formed by vertical welding of a large rectangular steel plate and a slender rectangular steel plate. a slender through hole.

The jig described in the technical proposal is an Ω-shaped thin plate part with circular through holes processed at both ends.

The T-shaped plate described in the technical proposal is formed by vertical welding of the upper rectangular steel plate and the bottom rectangular steel plate. A group of steel hemispheres are uniformly welded on the outer side of the upper rectangular steel plate. The bottom rectangular steel plate is processed by four circular channels. hole.

The base plate described in the technical proposal is processed from a rectangular steel plate, and the base plate is processed with four threaded holes.

The beneficial effects of the present invention are:

(1) The present invention adopts the detection mode of the fixed mark, the laser is connected with the wheel and moves synchronously, the mark is fixed, the accuracy of the measurement is improved, and the time for detection is greatly saved.

(2) main part of the present invention adopts standard section steel to process, at first, standard section steel output is big, and machining operation is few, and production cost is lower; Secondly, as the important annex of measuring instrument, adopt standard section steel to have certain strength, can It will not deform during long-term use, guarantee the accuracy of measurement, and can meet the requirements of national standards for measurement accuracy.
