Chinese patent CN 201508157U discloses a kind of simple and easy flat sided straight dimension measuring instrument on 06 16th, 2010, it is made of support body, benchmark leveling ruler, locating piece, clock gauge and gauge head; Described benchmark leveling ruler and locating piece are fixedly installed on the both sides, front and back of support body upper surface respectively, and the location division of locating piece is higher than benchmark leveling ruler upper end reference plane; Described benchmark leveling ruler is provided with a perforation that is positioned at locating piece the place ahead, and the clock gauge that the upper end connects gauge head is arranged in this perforation.

Thin wall cylindrical shell structure part causes such processing precision of products not high because the linearity of axis is poor, needs a cover bracing or strutting arrangement that the linearity of thin wall cylindrical shell structure part axis is accurately measured.

Existing supporting condition is difficult to satisfy the requirement of measuring accuracy, and existing supporting condition also is difficult to the real work state of model configuration spare.

The utility model content

The support problem that exists for the straight line degree measurement that solves thin wall cylindrical shell structure part axis, technical problem to be solved in the utility model is to provide a kind of axis verticality to measure employed bracing or strutting arrangement, this device both can the real simulation structural member duty, also can effectively improve the measuring accuracy after the support.

In order to solve the problems of the technologies described above, the bracing or strutting arrangement that the thin wall cylindrical shell structure part axis verticality that the utility model provides is measured comprises portal frame assembly, carriage assembly and guidance set, wherein:

Above-mentioned portal frame assembly comprises worktable 1, preceding portal frame 8, back gantry 7, supporting lug 6, cushion block 4, second straight pin 21.By first bolted, position between worktable and preceding portal frame, the back gantry by first straight pin; Undertaken fastening by the 5th screw between supporting lug and the back gantry; Be connected with first, second nut by second, third bolt between worktable and the cushion block;

Above-mentioned carriage assembly comprises carriage 9 and circular arc supporting plate 5, is fastenedly connected by first screw between carriage and the circular arc supporting plate;

Above-mentioned guidance set comprises guide plate 2 and guide plate reinforcement 3, is fastenedly connected by the 4th screw between guide plate and the guide plate reinforcement.

It is poor that the utility model has solved the supporting condition of existing thin wall cylindrical shell structure part straight line degree measurement, the support measuring accuracy is low, problems such as the loaded down with trivial details and efficient of support operation is low, improve the support operation efficient of structural member and supported measuring accuracy, reached the beneficial effect of model configuration spare real work state.
