Measuring device for tool parameters of a two-dimensional image measuring instrument

Abstract

The invention relates to a parameter determination device for a cutter of a quadratic element image measurer. The middle part of a fixture base is adjustably connected with a cutter axle center finding and axial positioning mechanism and a sliding block through a connecting groove. The right end of the fixture base is adjustably connected with a pressing stirring mechanism. The sliding block is positioned between the cutter axle center finding and axial positioning mechanism and the pressing stirring mechanism. A locking mechanism is arranged on each of the cutter axle center finding and axial positioning mechanism and the sliding block. A second V-shaped positioning plate is fixedly connected to the front end face of the sliding block, and a first V-shaped positioning plate is fixedly connected to the right end face of the fixture base. The cutter is positioned and centered by the axle center finding and axial positioning mechanism and the V-shaped positioning plates to facilitate the accurate clamping of a product, parameters such as circular runout of the cutter are conveniently measured by the pressing stirring mechanism, the whole tool is unlimited to the parameter measurement of the cutter in a certain specification, and the pressing stirring mechanism is adjusted upwards and downwards to ensure practicability for cutters in different specifications.

Description

technical field [0001] The invention relates to a tool measuring device, in particular to a tool parameter measuring device for a two-dimensional image measuring instrument. Background technique [0002] Now there are a large number of two-dimensional image measuring instruments on the market. This instrument is suitable for all application fields aimed at two-coordinate measurement. It is widely used in industries such as machinery, electronics, instrumentation, hardware, and plastics. These instruments are generally used in When leaving the factory, the workbench is not equipped with any fixtures or the fixtures are too simple. Manufacturers of milling cutters and drills are typical representatives. Such instruments are widely used in the production process to measure tool parameters. However, due to the lack of special fixtures, it is inconvenient to operate during the measurement process, resulting in low production efficiency and greatly reducing enterprise benefits. ...

Milling cutter and drill bit manufacturers are typical representatives, and such instruments are widely used in the production process to measure tool parameters. However, due to the lack of special fixtures, it is inconvenient to operate during the measurement process, resulting in low production efficiency and greatly reducing enterprise benefits.

[0003] Xintian video measuring instrument is a kind of two-dimensional image measuring instrument, which can measure points, lines, circles, distances, angles, calculate true roundness, straightness, concentricity, etc., and can generate inspection reports in real time. In manufacturers, it is often used to measure various parameters of milling cutters, such as the blade diameter, groove length, blade length and the overall length of the cutter. Often in these manufacturers, it is also necessary to measure the blade length of the T-shaped cutter. The parameters of the blade diameter, blade length, and tool circular runout of the taper knife, while the existing simple tooling of the Xintian video measuring instrument limits the use of the instrument's functions, and its fixture is often just a simple V-shaped groove. When the circular runout parameter is reached, the tool is rotated only by hand, and because there is a large amount of lubricating oil on the production site, it is extremely inconvenient during the rotation of the tool. There is a taper in the axial direction, so if this instrument is used to measure the blade diameter of a tapered knife, it must be ensured that there is no movement in the direction of the axis during the tool measurement process, otherwise the measurement error will be large. Some actual production plans now use thimbles to withstand The axis is positioned axially, and the contact between the thimble and the workpiece is often point-to-surface contact. However, due to the influence of part manufacturing accuracy and fixture assembly accuracy, it is often difficult to accurately withstand the axis of the solution, resulting in Axial movement occurs when measuring the blade diameter of a tapered knife, and there is a large error. Therefore, some fixtures in actual use cannot play the function of the Xintian video measuring instrument well, and are often limited to the blade diameter, groove length, The measurement of parameters such as blade length greatly limits the function of the instrument, which not only increases production costs but also reduces production efficiency
