Abstract

The utility model provides an angle adjustable V-shaped frame. The technical scheme of the utility model is as follows: according to the angle adjustable V-shaped, a base and a V-shaped block are in arc surface matching; the radius of the arc is from 20 to 50 mm; the central angle of the arc is from 120 to 150 degrees; the two V-shaped surfaces of the V-shaped block form an angle of 90 degrees with a processed square groove arranged at an apex angle; the width of the upper end of the V-shaped block is from 30 to 90 mm; the height of the V-shaped block is from 40 to 100 mm; the V-shaped block can rotates for 45 degrees leftwards or rightwards along circumference; the high of the base is from 20 to 50 mm, and the width of the base is from 50 to 120 mm; the width of an angle plate is from 12 to 15 mm with scale from 0 to 45 degrees in bilateral symmetry; the width of an angle vernier is from 8 to 10mm with scale provided with 30 units; the angle plate is connected with the V-shaped block by a screw; the angle vernier is connected with the base by a screw; and a locking block is connected with the base through a locking screw. The angle adjustable V-shaped frame provided by the utility model is advantaged in simple structure, high measurement accuracy of an angle and a size as well as wide application range.

Description

A kind of adjustable angle formula V-type frame

Technical field

The utility model relates to a kind of adjustable angle formula V-type frame, belongs to mechanical field.

Background technology

The V-type frame can be used for the angle and the size subsidiary of workpiece clinoplane, and the workpiece clinoplane that the V-type frame that uses now can only corresponding single angle carries out angle and dimensional measurement, can't carry out angle and dimensional measurement to workpiece clinoplane at any angle.

Summary of the invention

The purpose of the utility model provides a kind of adjustable angle formula V-type frame, to workpiece at any angle clinoplane all can carry out the measurement of angle and size.

The technical scheme of the utility model is: a kind of adjustable angle formula V-type frame, to form by V-block, base, angle board, angle vernier, latch segment, lock-screw, and base is set to arc surface with V-block and cooperates, and arc radius is 20-50mm; The circular arc central angle is the 120-150 degree, and V-block two V-type face angles are 90 degree, and the drift angle place is provided with the technology square groove; V-block upper end width is 30-90mm, and the V-block height is 40-100mm, but V-block is along circumference left rotation and right rotation 45 degree; The base height is 20-50mm, and width is 50-120mm, and the angle board width is 12-15mm; Scale is a left-right symmetric 0-45 degree, and angle vernier width is 8-10mm, and scale is 30 lattice; Angle board is connected by screw with the V-block setting, and the angle vernier is connected by screw with the base setting, and latch segment is connected by lock-screw with base.

The effect that the utility model is useful is: simple in structure, the measuring accuracy of angle and size is high, and is applied widely.
