Background
In the prior art, the equipment manufacturing industry measures the angle of a large-scale structural part by using a plurality of section frames for one product, and has extremely strong specificity, high manufacturing cost and large occupied area; in addition, a disc-type turntable is required to be matched with an additional autocollimation light pipe, namely a collimator, so that the manufacturing cost is higher. Although the method can measure a plurality of angles of a large structural member, the operation procedure is complex, the requirement on the quality of an operator is high, multiple persons are required to work together, and the cost is high. Although the device in the prior art can complete the measurement task of a plurality of angles of a large structural part, the defects are obvious. In the prior art, a method for measuring the angle of a large structural part by using a chuck type sine table is not available.
Disclosure of Invention
In order to solve the defects in the prior art, the invention aims to provide a method for measuring the angle of a large structural part by using a chuck type sine table on a common machining site. The technical solution of the invention is as follows: chuck formula sine platform 6 comprises three-jaw chuck 1 (for lathe, milling machine three-jaw chuck) and circle axle 3, and bridge type circular arc board 2 can be dismantled and connect on three-jaw chuck 1's outer arc face, and circle axle 3 is arranged in under three-jaw chuck 1's the bottom surface (this structure has applied for patent), its characterized in that: during measurement, a measured part 5 is fixed on a three-jaw chuck 1, a chuck type sine table 6 and a height gauge 9 are placed on a working platform 8, and a lever dial indicator 4 is connected to the height gauge 9; finding out that the points A and B are zero by using the lever dial indicator 4 so as to align the bus of the tested part 5; placing the circular shaft 3 under the bottom surface of the three-jaw chuck 1, and taking the ridge line of the bridge type circular arc plate 2 as a support and an axis, so that an included angle between the axis of the measured part 5 and the bridge type circular arc plate 2 is 90 degrees; the optical angle limiter 7 is placed on the plane of the three-jaw chuck 1, the longitudinal and transverse bubbles on the optical angle limiter 7 are adjusted to be zero, and the angle D, E can be measured.
Compared with the prior art, the invention has the advantages that: the method for measuring the angle of the large-scale structural part is simple, the assembling, the disassembling and the measuring result are all quick and convenient, the method is easy to master, and the measured result is accurate. Saves labor and time and has high efficiency. Has little requirement on the environment. The big problem is solved by a soil method. Can be widely applied to common machining sites. The novel plastic bag has the advantages of low cost, easy modification, novelty, creativity and practicability.
