Problems solved by technology

The caliper is equipped with three measuring rods on an ordinary caliper with a main ruler and an auxiliary ruler. Two of the fixed rods are installed on the main ruler, and the other moving rod is installed on the auxiliary ruler and moves relative to the fixed rod with the auxiliary ruler. When the two fixed rods and one moving rod are in contact with the measured arc at the same time, the coordinates of the three contact points are used together with the same electronic circuit and capacitive sensor as the electronic quantity caliper to calculate the radius corresponding to the arc, and the caliper finally The radius corresponding to the measured object can be measured through the inferior arc, but the caliper must be combined with its corresponding electronic device, the measurement procedure is cumbersome, and the production cost is high

Embodiment Construction

[0012] see figure 1 , which shows the overall structure of the appearance of an embodiment of the multifunctional caliper proposed by the present invention. This kind of caliper includes a main scale 1, an auxiliary scale 2, and a depth measuring claw 3.

[0013] One end of the main scale 1 is provided with two fixed measuring claws 11 and 12 in opposite directions and in the same plane, and a main vernier 13 movable along its axial direction is installed on the main scale 1, and on the main scale 1 A sliding measuring claw 14 corresponding to the fixed measuring claw 11 is installed on the vernier 13, and the fixed measuring claw 11 and the sliding measuring claw 14 are used for measuring the diameter of a part or a workpiece. The side of the main scale 1 away from the fixed measuring claw 11 is hollow, and the depth measuring claw 3 can extend into the hollow part of the main scale 1 and move along its axial direction to measure the depth of the workpiece.

Abstract

The invention relates to a multi-functional caliper which comprises a main graduated ruler with a fixed measuring claw and a sliding measuring claw, an auxiliary graduated ruler arranged vertically on the main graduated ruler and sliding thereon in the axial direction, an auxiliary sliding measuring claw arranged on an auxiliary vernier of the auxiliary graduated ruler relative to the fixed measuring claw on the main graduated ruler, and a chord height-measuring claw axially arranged on the auxiliary graduated ruler. The caliper is used to measure the chord height of a minor arc and also to measure the depth of a work piece. The caliper has multiple measuring functions with less increase in fabrication cost.

Description

[0001] Field: [0002] The invention relates to a multifunctional caliper used for measuring the inner diameter or outer diameter and chord height of objects such as cylinders and / or round pipes. Background technique: [0003] A vernier caliper is a measuring tool used to measure the inner and outer diameters or thickness of machine parts or workpieces. It consists of a long ruler with a scale, a fixed measuring claw installed at one end of the long ruler, and a sliding measuring claw set on the vernier. When using this kind of measuring tool to measure machine parts or workpieces, its maximum range depends on the length of the caliper, and it is limited to measuring the inner and outer diameters or thickness of machine parts or workpieces, but cannot measure the diameter of the object corresponding to the inferior arc. [0004] Aiming at the problems referred to above, Chinese Patent No. 155478 discloses a technology called "caliper". The caliper includes a fixed scale or sc...
