Detailed Description

The invention will now be described in further detail with reference to the drawings and preferred embodiments. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

The checking fixture for the auxiliary test of the size of the support is used for being placed on a test bench to detect a tested part 4, as shown in fig. 2-3, the middle positions of four sides of the tested part 4 are provided with tested part clamping

foot test surfaces

41, 2 tested part positioning holes 42 are formed in the bottom surface of the tested

part

4, and 4 limiting ribs 43 are arranged on the inner wall of the top end of the tested part 4.

The utility model provides an examine utensil for auxiliary test support size, is including examining a body 5, examines the cross-sectional shape of a body 5 and is "T" style of calligraphy of falling, examines a body 5 and includes supporting shoe 1 and reference platform 2, install supporting shoe 1 on the reference platform 2, surveyed part 4 cover on supporting shoe 1, the upper surface of supporting shoe 1 contacts with spacing muscle 43 on being surveyed part 4, installs locating pin 3 on the reference platform 2, and locating pin 3 inserts in being surveyed part locating hole 42 on being surveyed part 4.

Wherein, the lower surface of benchmark platform 2 sets up with the upper surface parallel of supporting shoe 1, and the lower surface of benchmark platform 2 sets up with the surperficial laminating of testboard. The reference table 2 and the supporting block 1 are of an integrally formed structure and are directly manufactured by a high-precision machining center, and the high-precision requirements on the parallelism and position precision relation between the upper surface of the supporting block 1 and the lower surface of the reference table 2 can be met.
