a v-iron

Abstract

The invention discloses V-shaped iron, and relates to the field of mechanical auxiliary tools. The V-shaped iron comprises a V-shaped iron body. The V-shaped iron body is provided with a V-shaped groove. Two shaft supporting surfaces are arranged on the two side walls of the V-shaped groove correspondingly. A through groove is formed in the V-shaped groove. Openings in the two ends of the through groove are provided with cover plates correspondingly. An upper sliding block and a lower sliding block are arranged between the two cover plates. A lead screw is horizontally inserted into one of the cover plates. The lead screw is in threaded connection with the lower sliding block. The lower sliding block and the upper sliding block are provided with oblique planes which are in sliding fit with each other. The other side of the upper sliding block is in sliding fit with the other cover plate. At least one pair of rollers used for supporting shaft parts are arranged at the upper end of the upper sliding block. The lower sliding block can be pushed by rotating the lead screw, displacement in the horizontal direction of the lower sliding block is converted into displacement in the vertical direction of the upper sliding block, and thus the upper sliding block can move upwards. The rollers installed on the upper sliding block stretch out of the two shaft supporting surfaces of the V-shaped groove so that the parts can be jacked up. The parts are supported between the two rollers, and the shaft parts can be rotated easily through the two rollers.

Description

technical field [0001] The invention relates to the field of mechanical auxiliary tools, in particular to a V-shaped iron. Background technique [0002] In the process of machining precision shaft parts, V-shaped irons are usually used to inspect or correct shaft parts. V-shaped irons consist of two pieces. When inspecting or correcting the shaft parts, place the shaft parts in the V-shaped grooves of two V-shaped irons, find the center line of the V-shaped irons through the V-shaped grooves, and then find the shafts placed on the V-shaped irons. The center line where the center of the part is located, rotate the shaft part, and inspect or correct the shaft part from different angles. [0003] Because rotating the shaft parts directly on the V-shaped iron not only requires a huge force, but also easily damages the workpiece or the V-shaped iron during the rotation process, so it is usually necessary to use lifting equipment to cooperate with the workpiece to turn over.
