Detailed Description

In the embodiment, referring to fig. 1 to 3, X-direction slideways 2 which are parallel to each other are respectively arranged on the inner side and the outer side of the upper surface of a base frame 1 of a large heavy shaft workpiece marking tool, a first V-shaped support 5 is fixedly arranged on the base frame 1 on the left side of the middle of the two X-direction slideways 2, a second V-shaped support 12 is fixedly arranged on the base frame 1 on the right side of the middle of the two X-direction slideways 2, and a central connecting line of the first V-shaped support 5 and the second V-shaped support 12 is parallel to the two X-direction slideways. The two X-direction slideways 2 are respectively connected with X-direction sliding blocks 3 in a sliding mode, the upper ends of the X-direction sliding blocks 3 are respectively and fixedly connected with a connecting plate 4, the upper ends of the connecting plates 4 are respectively and fixedly connected with the lower ends of the upright stanchions 6, and the cross rods 7 are fixedly connected between the upper ends of the two upright stanchions 6. A Y-direction slide way 8 is fixedly arranged on the cross rod 7, a Y-direction slide block 9 is connected on the Y-direction slide way 8 in a sliding mode, a measuring rod seat 11 is fixedly connected on the Y-direction slide block 9, a measuring rod 10 with scales vertically and movably penetrates through the measuring rod seat 11, and a workpiece 13 is placed on the V-shaped support I5 and the V-shaped support II 12.

The use method of the large heavy shaft workpiece scribing tool comprises the following steps: when the measuring device is used, a workpiece 13 is placed on the first V-shaped support 5 and the second V-shaped support 12 through the heavy crane, the X-direction slide block 3 slides on the X-direction slide way 2 and the Y-direction slide block 9 slides on the Y-direction slide way 8, and the size of the critical position of the workpiece 13 is measured through the measuring rod 10 with scales. First, the graduated measuring rod 10 is moved to the highest point of the left end of the workpiece 13, and the graduated measuring rod 10 is read. 3-7 key points are selected for measurement according to different workpieces 13, and the following description is given according to the measurement of 7 key points: 7 key points are selected from the left end to the right end, the radial peak size of each key point is measured through the measuring rod with the scales 10, the workpiece 13 is turned over for three times through the crane, the turning angle is 90 degrees every time, and therefore through the three-time measurement after turning, each key point can measure the four radial peak sizes of the upper portion, the lower portion, the inner portion and the outer portion of the measuring position through the measuring rod with the scales 10. And obtaining a numerical value obtained by dividing the sum of the sizes of two groups of opposite radial highest points of 7 key points by 2 to obtain two bending curves of the workpiece 13 in the vertical direction and the internal and external directions, and performing offset positioning on the left and right central holes of the workpiece 13 according to the blank machining amount of the 7 key measuring points.
