Detailed Description

In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined below to clearly and completely describe the technical solution of the embodiments of the present invention. It is to be understood that the embodiments described are some, not all embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the present invention, belong to the protection scope of the present invention.

As shown in fig. 1-2, a special auxiliary support for drawing a gauge length line comprises a base 1, an optical axis 7, a bearing support 3, a positioning slider 5 and a guiding positioning plate 4, wherein a rectangular groove 8 for bearing the optical axis 7 and a V-shaped groove 2 for placing a test piece are formed in the base 1, and the rectangular groove and the V-shaped groove 2 are parallel to each other; the two ends of the optical axis 7 are respectively connected with the base 1 through the bearing support 3, the bearing support 3 is a standard component of KFL08 type, the optical axis 7 is fixed, the diameter of the optical axis 7 is 8mm, and the bearing support 3 is provided with a set screw 9, so that the fixed optical axis 7 can not move and depart from the base in the axial direction while rotating in the axial direction; the optical axis 7 is movably provided with two positioning sliders 5, each positioning slider 5 is provided with a guide positioning plate, the positioning sliders 5 are tightly installed on the optical axis 7 and can smoothly slide on the optical axis 7 without loosening, the positioning sliders 5 can be locked and fixed on the optical axis 7 by locking screws 6, and after the positioning sliders 5 are fixed, the positioning sliders 5 and the guide positioning plates 4 form a whole body which can be turned up and put down along the axial direction of the optical axis at a certain positioning distance without loosening left and right under the action of the bearing support 3, so that the aim of preventing the guide positioning plates 4 on the positioning sliders 5 from clamping a test piece and being incapable of being taken out is achieved, and a plurality of test pieces are convenient to replace; the guiding and positioning plate 4 is close to one side of the V-shaped groove 2 and is provided with a triangular pointed block 10, one side of the guiding and positioning plate far away from the V-shaped groove 2 is provided with a positioning lug 11, the inner side edge of the positioning lug 11 is aligned with the pointed end of the triangular pointed block 10, the triangular pointed block 10 is used for pointing to the position of a test piece required marking distance, the positioning lug 11 with the width of 3mm plays a guiding role, the vernier caliper is clamped on the two positioning lugs 11 during use, the inner edge of the positioning lug 11 is aligned with the triangular pointed block 10, and therefore the pointed end position can accurately reflect the reading of the vernier caliper.
