Embodiment 1

[0024] Embodiment 1: see specification attached figure 1 , attached figure 2 And attached image 3 , the quantitative measuring caliper of the present invention comprises web 5, fixed measuring arm 1, elastic measuring arm 7, dial indicator 10, dial indicator fixing frame 6, spring 8, handle 4, measure zero gauge 11 and zero gauge Base12. The web is a rectangular plate. The length of the web is equal to the average value of the maximum tolerance size and the minimum tolerance size of the part to be measured. The two sides of the length direction of the web are parallel to each other; the fixed measuring arm is a rectangular block with a The hole connected to the plate is fixed and connected to one side of the web length direction with screws. One surface of the measuring arm should be in contact with the workpiece to be measured, and the contact point is a, so the contact end of the fixed measuring arm and the workpiece should be cantilevered out , the protruding length is...

Abstract

The invention discloses a quantitative measurement caliper gauge and belongs to measuring instruments. The quantitative measurement caliper gauge is used for measuring the diameters of high-precision shaft type workpieces in the production process in a workshop. The quantitative measurement caliper gauge comprises a dial indicator, a caliper gauge body and a zero calibration device. The caliper gauge body is composed of a web plate, a fixed measuring arm, an elastic measuring arm, a dial indicator fixing frame, a spring and a handle. The zero calibration device is composed of a measurement zero calibration gauge and a measurement zero calibration gauge base. The two edges, in the length direction, of the web plate are parallel. The fixed measuring arm is installed on one edge, in the length direction, of the web plate, the elastic measuring arm and the dial indicator fixing frame are installed on the other edge, in the length direction, of the web plate. A traditional integrated type caliper gauge structure is changed into a separable combination type caliper gauge structure. The quantitative measurement caliper gauge meets the Abbe principle, the measuring force is controlled, the number of links generating errors is reduced, and the measuring precision is improved. The actual sizes of the workpieces can be accurately measured. The quantitative measurement caliper gauge can be used for measurement in the machining process.

Description

technical field [0001] The patent of the invention belongs to measuring instruments, and specifically relates to a caliper for measuring the diameter of high-precision shaft workpieces in the factory production process. Background technique [0002] In the batch manufacturing process of the factory, only by processing high-precision mechanical parts can it be possible to manufacture high-quality equipment. High-precision part size is the basic requirement of high-precision parts. In traditional manufacturing, the high-precision outer circle size is generally ground out, and the size of the part has a tolerance zone. After the processing is completed, the caliper is used to check whether the processing size is qualified. The measuring part of the ordinary caliper has a through end and a stop end. When inspecting the workpiece, as long as the through end can pass and the stop end cannot pass, it is a qualified product. The shortcomings of this caliper are: 1) It can only che...
