Description

Known instrumental microscopes and projectors e.1 geometric measurements, parameters of tail cutting tools are used only on the condition of a small aiin of these tools; for measuring end surfaces, these devices we use.

However, the use of these optical instruments for monitoring the geometrical parameters of cutting tools is not economically feasible.

Proposed from the measuring (microscope for control .1: cold and angular bodies with a stand, tube and table, equipped with a 90 ° iris installed in the table groove for installation of the product, suitable for measurement, and reflective which changes the direction of the light beams in the microscope, this allows measuring the geometrical parameters of the end surfaces of the tailing tools.

FIG. 1 shows the proposed microscope design, side view; in fig. 2 is a front view; in fig. 3 shows a removable sleeve.

The optical system of the microscope and the reading device are mounted on the bracket. The images are observed through the ocular, ukreilenny in the rotary sleeve 2. In the field of view there is a grid with two mutually perpendicular: a circular line and a scale with a division interval of 0: 2 mm for counting linear magnitudes. Counting angular values Produced with the aid of a streak 3 according to degree 4. For upper inspection, an electric lamp serves as an instrument; 11) on a holder; when measuring the end surfaces of monitored products, directing the path of the light rays in mils: a drill and a 90 ° prism 8 for installing checked products. For installation in the prism of products with a tapered tail. Shifts. sleeve 9.; . 97452 The table is installed in such a way that the axis 8 passes through the optical axis of the microscope. For lower illumination of the instrument being turned on, an electric lamp serves, stirring, put it in the hatch, covered with a transparent plate 1G. When checking the angle of inclination, eccentricity, width of the transverse edge and centricity of the core of the drill, the measurement is performed in a plane perpendicular to the axis of the tool being tested using a reflective prism. In this case, the distance from the reflective prism 7 to the installation prism 8 is chosen so that the eye section of the end section has a face section of the inostrum to be checked. The measurement is carried out with overhead lighting, the linear parameters are read on a scale printed on the ocular grid. During the inspection of the angle at the top and the angle of the intake cone at the sweeps, the measurement is made in transmitted light (at the lower display), when the shadow image of the tool is recorded at the eye of the receiver. A, and checking the back angle and the angle of inclination of the helical grooves at drills, reamers and countersinks, the measurement is performed in a plane parallel to the axis of the tool under high light. P 1) With d mt m and 3 about the b e and Measuring microscope | To measure the linear and angular lead, which has a rack, tube and table, characterized in that:: the purpose of measuring geometric p Parameters 1 and, including the end surfaces of the tail cutting tools, it is equipped with a 90 ° prism installed in the table groove for mounting the tested product with a reflective prism that changes the direction of the light beams in the microscope.
