Description

TECHNICAL FIELD

[0001] The utility model mainly relates to the precision measurement field, concretely relates to a slider multi-specification precision detection device. BACKGROUND

[0002] As a key basic component, the slider is widely used in various precision guide rail systems, linear transmission mechanisms, automation equipment, numerical control machine tools, semiconductor equipment and other high-precision fields. Its machining precision (including size precision, shape and position tolerance, surface quality, etc.) directly determines the running stability, positioning precision, service life and overall performance of the equipment. With the development of high-end manufacturing, the precision requirement of the slider is increasingly stringent, and it usually needs to reach the micron level or even sub-micron level.

[0003] The utility model person found the following defects in the specific embodiment operation process:

[0004] Early detection mainly relies on manual operation of a dial gauge or a dial gauge to take point measurement, which needs to frequently turn over the slider and replace the clamp, resulting in low detection efficiency (single piece detection time is more than 30 minutes) and easy introduction of human error (such as uneven force, measurement displacement, etc.). For example, after detecting a plane, the workpiece needs to be turned over and repositioned, and the cumulative error can reach ±0.01mm or more, affecting the final precision judgment.

[0005] Different specifications of the slider need to customize special clamps, and the changeover time is long (about 15-30 minutes / time), which is difficult to adapt to the demand of multi-variety and small-batch production. For example, the fixed clamp in Japanese patent JP1999281341A can only adapt to a specific size of the slider, and cannot realize rapid adjustment.

[0006] Traditional equipment focuses on a single parameter (such as flatness), and lacks comprehensive detection capability for multi-dimensional parameters such as perpendicularity, span, friction coefficient, etc. For example, patent JP2008010029A only supports appearance inspection and cannot evaluate the dynamic performance of the slider (such as wear and tear, moving speed stability).
