Abstract
The invention provides a shaft key groove symmetry degree measuring device for measuring the symmetry degree of workpiece shaft key grooves. The shaft key groove symmetry degree measuring device comprises a base and a measuring mechanism, wherein the measuring mechanism is arranged on the base, is in an inverted- shape and comprises a cross rod and three vertical rods. The vertical rods include two side vertical rods and a middle vertical rod, each of the base and the cross rod is provided with a sliding way for the corresponding vertical rod to move, each of the cross rod and the vertical rods are provided with scales, the side vertical rods are provided with pins, the pins are used for positioning the key grooves, laser devices are arranged on the faces opposite to the key grooves, of the pins, a measuring ruler is arranged on two sides of the middle vertical rod in the vertical direction respectively, starting scales of the two measuring rulers are opposite, the measuring rulers are connected through a transparent film, and a laser device is arranged at one end of the transparent film. The shaft key groove symmetry degree measuring device utilizes laser rays to mark central lines and perpendicular lines of the two key grooves and then utilizes the two measuring rulers opposite in starting point and the laser rays to measure the symmetry degree of the key grooves.
Description
Technical field
The invention belongs to machining Seiko fields of measurement, especially relate to a kind of device for measuring key slot symmetry degree of shaft.
Background technology
Prior art mainly contains V shape iron, flat board, dial gauge and gauge stand for axle keyway symmetry measuring method, and these method measuring processs are loaded down with trivial details, and precision reliability is poor.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of device for measuring key slot symmetry degree of shaft, solves axle keyway symmetry in prior art and measures the problem loaded down with trivial details, precision is not high.
For solving the problems of the technologies described above, the technical solution used in the present invention is: device for measuring key slot symmetry degree of shaft, for the symmetry of measuring workpieces shaft key groove, comprise base, measuring mechanism, described measuring mechanism is located on base, and shape is as the ш stood upside down, comprise a cross bar and three montants, described montant comprises montant in the middle of two side montants and, described base and cross bar are equipped with the slideway moved for montant, described montant is equipped with scale, for determining that two keyway lines are horizontal line, side montant is provided with bearing pin, described bearing pin is used for keyway location, the opposite face of bearing pin and keyway is provided with laser instrument, the laser that described laser instrument is launched is for connecting two key slot center lines, described middle montant vertically both sides is respectively provided with a dip stick, and two dip stick start index are contrary, be connected by a hyaline membrane between two dip sticks, hyaline membrane one end is provided with laser instrument, described laser instrument is used to indicate the perpendicular line of two key slot center lines, described dip stick is for measuring the distance with downside on the upside of two laser rays intersection points and workpiece, thus determine the symmetry of detection.
Further, have one in described bearing pin at least and be provided with laser instrument.
Further, described bearing pin is provided with laser switch.
Further, described middle montant is at least provided with laser instrument in one end.
