Abstract

Multifunctional projection measuring caliper comprises a fixed length lower convex edge (0), a fixed length groove (1), an inner measuring ruler (2), a digital display gauge outfit (3), a depth measuring ruler (4), an outer measuring ruler (5), a magnifier (6) and a movable ruler (7), and solves the problem that the prior art caliper cannot perform projection measurement. The utility model discloses chimb (0) under the scale, be a cuboid arch below the scale, form or form with the equipment of correct grinding stainless steel cuboid and screw with scale integrated into one piece. The magnifier (6) is made of glass or transparent resin materials and is scribed by laser, and the magnifier can be processed and manufactured by the prior art and the process. The measuring time and the cost of machining can be saved, and the projection measuring tool is a practical and low-cost projection measuring tool.

Description

Multifunctional projection measuring caliper

Technical Field

The multifunctional projection measuring caliper can be used for measuring machining (turning, milling, planing, grinding and clamping), and can be used for measuring the projection measurement of inner diameter, outer diameter, depth, step and irregular surface, and the common measurement and projection measurement of mechanical inspection.

Background

The projection measurement of the common caliper is inaccurate in positioning, so that the estimation is not accurate enough, and the multifunctional projection measurement caliper has the advantages of positioning the convex edge under the fixed length and measuring the amplified details of the magnifier to improve the precision. And the market price of the professional projection measuring instrument is about thousands to tens of thousands of RMB, the installation and the use are inconvenient in a processing field, and professional operators are needed.

Disclosure of Invention

The projection measuring instrument used for machining is high in manufacturing cost and use cost, the caliper cannot be used for projection measurement in the prior art, inconvenience and deficiency are brought to machining measurement, and the caliper is improved in the prior art.

A multifunctional projection measuring caliper is composed of a fixed-length lower convex edge (0), a fixed-length groove (1), an inner measuring ruler (2), a digital display gauge outfit (3), a depth measuring ruler (4), an outer measuring ruler (5), a magnifying glass (6) and a movable ruler (7). A multifunctional projection measuring caliper is characterized in that a fixed-length lower convex edge (0) and a magnifying lens (6) are additionally arranged. The projection measurement of the caliper is solved.

The multifunctional projection measuring caliper has the advantages that: the caliper has more projection measurement functions than a common caliper and can also be used as the common caliper. The whole small and exquisite low in manufacturing cost can hand-carry, makes things convenient for machining field survey and projection measurement to use, also need not professional training operating personnel. The multifunctional projection measuring caliper is a new measuring tool which can reduce cost and improve benefit.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings, referring to fig. 1 and 2.

The components in fig. 1 are labeled as follows: 0. the lower fixed-length convex edge, 1, the fixed-length groove, 2 and the inner measuring scale; 3. A digital display meter head; 4. a depth measuring scale; 5. An external measuring ruler; 6. A magnifying glass; 7. And (6) moving the ruler.

The multifunctional projection measuring caliper increases the shadow part of the convex edge under the fixed ruler to exceed the movable ruler, a measuring step is arranged between the fixed ruler and the movable ruler, and the surface of the large mirror of the movable ruler is provided with a cross-shaped measuring reticle. The multifunctional projection caliper is used in three steps, 1, a lower flange of a fixed ruler is tightly fixed or positioned on one side of a measured object, 2, a movable ruler is slid to a measured point and is aligned to a measured point of the measured object through scribing of a magnifier, and 3, a digital display meter reads a measured value.

FIG. 2 is a schematic view of a 90 degree V groove machined in the center of a cube material to measure V width using the novel invention.

The method comprises the following steps: the edge of the processed material is positioned by using a fixed-length lower flange, a vertex digital display table is reset by using the projection of a mirror, and the other vertex is measured by using the same method, so that the measured value can be directly read. The method is used for measuring the value from the edge of the measurable material to the center of the V-shaped groove once, and the position symmetry value of the V-shaped groove and the cubic material can be obtained through multiple times of measurement and calculation.
