the leveling device for assisting in measuring the local height of the ring piece comprises a base 1, wherein an annular positioning spigot 2 is mounted on the base 1, a step surface is arranged on the outer circumference of the positioning spigot 2, a plurality of threaded holes are uniformly distributed in the step surface, supporting screws 3 are mounted in the threaded holes, a pointer 4 is arranged on the outer side of each supporting screw 3, the pointer 4 is slidably mounted on a sliding rod 7, and the sliding rod 7 is fixed on the base 1.
The bottom of the sliding rod 7 is provided with a sliding rod seat 8, the sliding rod 7 is sleeved with a pointer seat 5, the front end of the pointer seat 5 is provided with a pointer 4, and the rear end of the pointer seat is provided with a puller screw 6.
Three threaded holes are formed in the positioning spigot 2 and are spaced by 120 degrees.
The cross section of the sliding rod 7 is trapezoidal.
The inner circle of the positioning spigot 2 is provided with a cross-shaped reinforcing structure.
On the plane projection, the circle center of the positioning spigot 2, the threaded hole and the pointer 4 are in the same straight line.
The leveling process comprises the following steps: firstly, the height of the pointer seat 5 is adjusted to enable the three pointers 4 to be at a preset height, then a ring piece to be leveled is placed on the positioning seam allowance 2, the lower end face of the ring piece is contacted with the three supporting screws 3, and finally the supporting screws 3 are adjusted to enable the three pointers 4 to be flush with the scribed lines on the outer circumference of the ring piece.
The height is adjusted by rotating the nut of the supporting screw 3.
The invention has the beneficial effects that:
the pointer is connected with the pointer seat, the pointer seat slides on the sliding rod, and the displacement of the pointer seat is limited by the jacking screw; the sliding rod is connected with the sliding rod seat, and the base is connected with the sliding rod seat; the supporting screw at the position 3 is connected with the positioning spigot part through threads, and the positioning spigot part is connected with the base; the pointer points to the scribed line of the part to be measured, and the scribed line of the part to be measured is leveled by adjusting the supporting screw, so that the measuring efficiency is improved, the measuring cost is saved, and the operation is simple and easy to realize on the premise of ensuring the measuring precision.

Detailed Description
Example (b):
the specific implementation mode is as follows: the leveling mechanism for auxiliary measurement consists of a base 1, a positioning spigot 2, a supporting screw 3, a pointer 4, a pointer seat 5, a jacking screw 6, a slide bar 7, a slide bar seat 8 and a screw 9; the base 1 is used as a base, the base 1 is of a disc type structure, the base 1 is connected with a positioning spigot 2, 3 threaded holes are uniformly distributed on the bottom surface of the positioning spigot 2, a supporting screw 3 is in threaded connection with the positioning spigot 2, and a pointer 4 points on an excircle horizontal line of a measured piece by rotating the supporting screw 3, so that the measured piece is in a horizontal state. And (4) measuring the required height dimension by a dial indicator on a numerical control machine tool. The pointer 4 is connected with the pointer seat 5, the pointer seat 5 is in matching contact with the sliding rod 7, the pointer seat 5 slides up and down on the sliding rod 7, and the height of the pointer 4 is adjusted. When the height is adjusted to the level reticle of the pointer 4 pointing to the measured piece, the jacking screw 6 is screwed down, the position of the pointer seat 5 is fixed, and the position fixation of the pointer 4 is realized.
