Problems solved by technology

in the right figure 1 When measuring on the upper part of the workpiece as shown (especially figure 1 The middle circle part A and B), this kind of workpiece not only requires the diameter to meet the standard (that is, the diameter between A and B), but also requires the left and right "tapers" of the opening to the side to meet the standard. In this case, The use of vernier calipers alone cannot meet the needs

Embodiment 1

[0022] Such as Figure 1-4 As shown, a vernier caliper with auxiliary parts includes a main scale, a vernier, an inner jaw for measuring the inner diameter, and an outer jaw for measuring the outer diameter. The free claws, the corresponding ends of the fixed claws 41 and the free claws 42 are respectively provided with an auxiliary piece 5, and the auxiliary piece 5 has an integrally formed U-shaped fixed part 51 and an arc-shaped measuring part 52, and the U-shaped fixed part 51 passes through the open The locking slot 53 is connected with the fixed claw 41 or the free claw 42 , and one side of the locking slot 53 also has a fixing hole 54 . The fixing hole 54 is a threaded fixing hole. The auxiliary member is fixed on the fixed claw 41 and the free claw 42 through the fixing hole 54 by using fasteners such as bolts.

[0023] The ends of the fixed claw 41 and the free claw 42 also have a first magnet, and the slot 53 of the U-shaped fixed part 51 has a second magnet 55 , a...

Embodiment 2

[0027] A vernier caliper with auxiliary parts, including a main ruler, a vernier, an inner measuring claw for measuring the inner diameter and an outer measuring claw for measuring the outer diameter, the outer measuring claw includes a fixed claw fixed on the main ruler and a free claw sliding with the vernier, It is characterized in that an auxiliary part is provided at the corresponding ends of the fixed claw and the free claw, and the auxiliary part has a U-shaped fixing part and an arc-shaped measuring part integrally formed, and the U-shaped fixing part passes through the opening slot It is connected with the fixed claw or the free claw, and one side of the slot also has a fixed hole. The fixing holes are threaded fixing holes.

Abstract

The invention discloses a vernier caliper with auxiliary parts, which comprises a main ruler, a vernier, an inner measuring claw for measuring the inner diameter and an outer measuring claw for measuring the outer diameter, the outer measuring claw includes a fixed claw fixed on the main ruler and slides with the vernier The free claws, the corresponding ends of the fixed claws and the free claws are respectively provided with an auxiliary part, and the auxiliary parts have a U-shaped fixed part and an arc-shaped measuring part integrally formed, and the U-shaped fixed part passes through the opening slot It is connected with the fixed claw or the free claw, and one side of the slot also has a fixed hole. The caliper of the invention is easy to use, has high measurement accuracy, and can fulfill the requirement of measuring a specific measurement point of a specific workpiece.

Description

technical field [0001] The invention relates to a vernier caliper, in particular to a vernier caliper with auxiliary parts. Background technique [0002] Vernier caliper is a commonly used measuring tool for measuring length, inner and outer diameters, and depth. The vernier caliper is composed of two parts, the main ruler and the sliding vernier attached to the main ruler. in the right figure 1 When measuring on the upper part of the workpiece as shown (especially figure 1 The middle circle part A and B), this kind of workpiece not only requires the diameter to meet the standard (that is, the diameter between A and B), but also requires the left and right "tapers" of the opening to the side to meet the standard. In this case, Vernier calipers alone cannot meet the demand. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a vernier caliper with auxiliary parts, which ca...
