As shown in figure 1, the verticality detection device for the arc cutting edge of the workpiece comprises a detection platform, a detection board and coloring powder, wherein a detection surface 1 is arranged on one side of the detection board, two ends of the detection board are respectively and fixedly connected with a bottom plate 2, the bottom plate 2 is vertically connected with the detection board, the detection surface 1 is an arc surface with a fixed radius, and the coloring powder is coated on the detection surface 1. Place work piece 3 in the inspection platform, will have the inspection face 1 of colored powder to be close to the blade face 4 of work piece 3, gently push the scraping, judge the straightness that hangs down of blade through the colored condition of blade face 4. If the colored powder can be observed at each position of the edge face 4, the verticality of the edge face 4 is good, and if the colored powder cannot be observed at a certain position, the verticality is poor, and the processing is needed.

Furthermore, the inspection surface 1 is formed by connecting two arc surfaces with different radiuses.

Further, the radius of one section of the inspection surface 1 is R3mm, and the radius of the other section of the inspection surface 1 is R5 mm. The check surface 1 of R3mm and the check surface 1 of R5mm cooperate so that the detection device can accommodate the detection of the perpendicularity of most of the land surface 4. The smaller the radius of the arc surface is, the higher the inspection precision is. The radius of the arc surface is large, the inspection speed is high, but the precision is reduced.

Further, the hardness of the test surface 1 is HB240-260, and the maximum allowable value of the surface roughness Ra is 5 μm. The inspection surface 1 and the cutting edge surface 4 need to be scraped mutually, and the inspection surface 1 needs to meet certain hardness and surface roughness. Indicating that too high a roughness will damage the land surface 4, indicating that too low a roughness will make it less likely that the colored powder will stick to the test surface 1.

Further, a handle 5 is connected between the two bottom plates 2.

Further, the coloring powder is blue lead or red lead.

Furthermore, one side of the inspection surface 1 is sequentially connected with a first transition curved surface 6, a first plane 7 and a second plane 8, the other side of the inspection surface 1 is sequentially connected with a second transition curved surface 9, a third plane 10 and a fourth plane 11, the first plane 7 is parallel to the third plane 10, the second plane 8 is connected with the fourth plane 11, two ends of the first transition curved surface 6, two ends of the first plane 7, two ends of the second plane 8, two ends of the second transition curved surface 9, two ends of the third plane 10 and two ends of the fourth plane 11 are respectively and vertically connected with the bottom plate 2, an opening 12 communicating the middle part of the connection part of the third plane 10 and the fourth plane 11 is arranged in the middle part of the connection part of the first plane 7 and the second plane 8, and the connection part of the opening 12 and the second plane 8 and the fourth plane 11 forms the handle 5. The handle 5 facilitates the operation of the detection device.
