[0041] like Figure 1 , Figure 2 As shown, the cylinder quadrant measurement auxiliary tool comprises a straight ruler 1 and at least one set of clamping mechanisms 2. The clamping mechanisms 2 are used to fix the straight ruler 1 on the cylinder 3.

[0042] The structure of the ruler 1 is as follows Figure 3 As shown, there is a scale portion 11 and at least one connecting portion 13. The upper side of the scale portion 11 is a measuring plane 12; the connecting portion 13 is located at the end of the scale portion 11 and the two are fixedly connected as one body; the scale portion 11 and the connecting portion 13 are preferably made as one body. The connecting portion 13 is used for assembling the clamping mechanism 2, and the number is preferably two, and the two connecting portions 13 are symmetrically arranged at the left and right ends of the scale portion 11; accordingly, the number of the clamping mechanism 2 is also two groups, and the two groups of clamping mechanisms 2 are respectively installed on the two connecting portions 13.

[0043] The connecting portion 13 is provided with a second adjustment hole 15, which penetrates the front and rear sides of the connecting portion 13. The second adjustment hole 15 corresponds to the end surface position of the cylinder 3 and serves as an observation hole for the quadrant line; the second adjustment hole 15 has at least one horizontal standard surface, which is in the same plane as the measuring plane 12. The position of the quadrant line can be observed through the second adjustment hole 15, and the measuring plane 12 can be aligned with the pre-drawn quadrant line through the horizontal standard surface. For example, the upper side and the lower side of the second adjustment hole 15 are parallel to each other and are both horizontal planes, and the upper side of the second adjustment hole 15 is used as the horizontal standard surface.

[0044] The connecting portion 13 is also provided with a first adjustment hole 14, which also penetrates the front and rear sides of the connecting portion 13. The first adjustment hole 14 is located inside the second adjustment hole 15, and the second adjustment hole 15 and the first adjustment hole 14 are preferably long holes and extend horizontally.

[0045] like Figure 1 , Figure 2 As shown, each set of clamping mechanisms 2 includes a locking adjustment member 21 , a support block 22 , a first locking member 23 and a second locking member 24 .

[0046] The support block 22 is fixedly mounted on the connecting portion 13. The support block 22 and the connecting portion 13 can be formed as follows: Figure 2In the bolt connection structure shown, specifically, the connection part 13 is processed with an assembly hole 16, which can be a light hole and penetrates the front and rear sides of the connection part 13; the support block 22 is processed with a threaded hole matching the assembly hole 16, and the connection part 13 is fixedly connected to the support block 22 by bolts or screws located in the light hole or the threaded hole. The support block 22 and the connection part 13 can also be connected by welding, bonding, etc., as long as the positions of the two are relatively fixed.

[0047] The first locking member 23 and the second locking member 24 are respectively clamped on two opposite sides of the cylinder wall of the cylinder 3 , and cooperate with each other to achieve relative fixation of the level ruler 1 and the cylinder 3 .

[0048] As one of the various embodiments, the first locking member 23 is located on the outside of the cylinder 3, and the second locking member 24 is located on the inside of the cylinder 3; accordingly, the outer clamping surface 232 on the first locking member 23 is a curved surface that is concave toward the inside, and the inner clamping surface on the second locking member 24 is a curved surface that is convex outward, so that the contact area with the cylinder 3 can be increased and the clamping stability can be improved. In addition, a rubber pad is adhered to the outer clamping surface 232 through the adhesive backing to increase the friction force when the first locking member 23 is locked with the cylinder 3, thereby preventing the straight ruler 1 from deflecting.

[0049] The second locking member 24 can be a roller bearing, and a second connecting shaft 27 is arranged in the first adjusting hole 14. The second connecting shaft 27 is adjustably mounted on the connecting portion 13 through nuts located on both sides of the connecting portion 13. The second locking member 24 is rotatably mounted on the second connecting shaft 27, and a rubber wheel 25 is sleeved on the outer side, which can increase the friction with the inner wall of the cylinder body 3 and prevent damage to the inner wall of the cylinder.

[0050] The first locking member 23 is block-shaped and is adjustably mounted in the second adjusting hole 15 via the first connecting shaft 26. Since the first adjusting hole 14 and the second adjusting hole 15 are long holes, the spacing between the first locking member 23 and the second locking member 24 can be adjusted to be suitable for cylinders 3 with different wall thicknesses; at the same time, the first adjusting hole 14 and / or the second adjusting hole 15 also have the function of observing whether the quadrant line coincides with the straight ruler.

[0051] like Figure 1 and Figure 4 As shown, the locking adjustment member 21 is rotatably mounted on the support block 22 and can push and pull the first locking member 23 , thereby achieving the clamping, fixing or releasing of the first locking member 23 and the second locking member 24 .

[0052] The locking adjustment member 21 has a first threaded portion 211, an avoidance recess 212 and a second threaded portion 213. The first threaded portion 211 and the second threaded portion 213 are coaxially arranged. The avoidance recess 212 is an annular groove and is located between the first threaded portion 211 and the second threaded portion 213. The outer diameter of the avoidance recess 212 is smaller than the outer diameter of the second threaded portion 213. A first threaded hole 221 is machined in the support block 22. The first locking member 23 has a second threaded hole 233 and an inner hole 231. The inner hole 231 is connected to the second threaded hole 233, and the diameter of the inner hole 231 is larger than the diameter of the second threaded hole 233. The first threaded portion 211 is screwed into the first threaded hole 221, and the second threaded portion 213 rotates through the second threaded hole 233 and enters the inner hole 231; when in use, the position of the second threaded hole 233 corresponds to the avoidance recess 212, and the second threaded portion 213 is in the inner hole 231; rotating the locking adjustment member 21 can drive the first locking member 23 to approach or leave the cylinder 3.

[0053] Furthermore, the end surface of the second threaded portion 213 is a spherical surface, and the inner end surface of the inner hole 231 is also a spherical surface; when the locking adjustment member 21 pushes the first locking member 23, the contact surface between the two is large and the interaction is stable.

[0054] When measuring, Figure 5 and Figure 6 As shown,

[0055] First, loosen the nut of the second locking member 24, and adjust the first locking member 23 to the maximum limit position through the locking adjustment member 21;

[0056] Then adjust the second locking member 24 to a suitable position, fully contact the inner wall of the cylinder 3, and tighten the nut. At this time, the cylinder quadrant measurement auxiliary tooling can be rotated on the inner wall of the cylinder. After rotating to a suitable position, the upper side surface of the second adjustment hole 15 coincides with the pre-marked quadrant line.

[0057] Then, the first locking member 23 is locked by the locking adjusting member 21 so that it is completely fitted with the outer surface of the cylinder 3;

[0058] After completing the above operations, the relevant dimensions can be measured by a laser tracker, and the laser target ball of the laser tracker is placed on the measuring plane 12 .

[0059] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
