Problems solved by technology

[0002] like figure 1 As shown, when measuring the inner diameter of a cylindrical casting, the conventional method is to put the cross caliper into the inner wall of the cylindrical casting, spread the cross caliper so that the two tips of the cross caliper press against the inner wall respectively, and then take out and measure the two The distance between the two tips is the inner diameter of the cylindrical casting, but because the casting will cause depressions and protrusions due to poor shrinkage during the solidification process, it is difficult to measure the cylindrical casting after the cross caliper is pressed against the inner wall of the cylindrical casting and cannot be taken out. inner diameter of

Embodiment Construction

[0012] Such as figure 2 As shown, a caliper includes a caliper main body 1, a sliding scale 2 is provided in the caliper main body 1, a chute 3 is provided on the caliper main body 1, and a scale is slidably connected in the chute 3 2 Tighten the bolts 4 connected. The scale mark on the top of the scale 2 is the height of the caliper main body 1 . The lower part of the caliper body 1 is provided with a measuring tip 5 . The caliper main body 1 and the measuring tip 5 are integrally structured. The height of the caliper main body 1 is 200mm, so the scale marks on the top of the scale 2 should be 200mm. When in use, the caliper is placed in a cylindrical casting, the sliding scale 2 is released, and the measuring tip 5 at the lower end of the caliper main body 1 is against it. The lower part of the cylindrical casting is depressed, and the upper end of the scale 2 is against the upper side wall of the cylindrical casting. The inner diameter of the cylindrical casting can be ...

Abstract

The invention provides a caliper ruler which comprises a caliper ruler body. The caliper ruler body is provided with a sliding calibrated scale and a chute. A screwing bolt connecting with the calibrated scale is slideably coupled to the chute. The caliper ruler can conveniently measure an internal diameter of a cylindrical casting, measurement is accurate, and an error is small.

Description

technical field [0001] The invention relates to a caliper. Background technique [0002] Such as figure 1 As shown, when measuring the inner diameter of a cylindrical casting, the conventional method is to put the cross caliper into the inner wall of the cylindrical casting, spread the cross caliper so that the two tips of the cross caliper press against the inner wall respectively, and then take out and measure the two The distance between the two tips is the inner diameter of the cylindrical casting, but because the casting will cause depressions and protrusions due to poor shrinkage during the solidification process, it is difficult to measure the cylindrical casting after the cross caliper is pressed against the inner wall of the cylindrical casting and cannot be taken out. inner diameter. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a caliper, which can conveniently and simply measure the inner diameter...
