In response to the particularity of comprehensive accuracy detection of rolling linear guide pairs, Kate Precision Machinery continuously develops and designs a rapid detection instrument for the comprehensive accuracy of guide pairs.

Firstly, install a gantry on the dedicated platform, which can move along the high-precision guiding mechanisms on both sides of the platform. Five non-contact measuring heads are installed on the crossbeam of the gantry through clamps and adjustment mechanisms. The clamps and adjustment mechanisms are used to adjust the position of the measuring heads in both height and width directions to adapt to the measurement of different models and specifications of guide rail pairs.

The mechanism composed of a side measuring head and a positioning rod is used to measure the deviation of the width direction of the guide rail pair, including the limit deviation of the size between the slider and the guide rail reference side, the size variation between each slider, and the parallelism of the movement of the slider reference side relative to the guide rail reference side.

The top measuring head is used to measure the height deviation of the guide rail pair, including the height limit deviation of the guide rail pair, the height variation between the sliders, the parallelism of the slider top surface relative to the guide rail bottom surface, and the deflection of the slider along the guide rail during full field motion.

The reference side head is used for compensating dynamic system errors in the height direction, achieving high-precision measurements. The encoder is fixed on the gantry frame through a connecting mechanism and meshes with a synchronous belt fixed on the lower side of the measuring platform through gears, for real-time monitoring of the movement position of the gantry frame. When measuring, synchronously move the gantry and the measured slider to collect data at various measurement positions on the guide rail. By comprehensively calculating the collected data, the comprehensive accuracy of the guide rail pair can be obtained, thus achieving the measurement of the comprehensive accuracy of the guide rail pair.
