Abstract

The invention relates to a special grating clamp for eccentric adjustment of an encoder circular grating. The special grating clamp comprises a clamp base, a clamping mechanism, a driving transmissionmechanism and an encoder circular grating mounting base. The clamp base is used for arranging the clamping mechanism and the driving transmission mechanism. The clamping mechanism comprises an upperclamping plate and a lower clamping plate; the encoder circular grating mounting base is arranged between the upper clamping plate and the lower clamping plate, the driving transmission mechanism drives the upper clamping plate and the lower clamping plate to move oppositely, and clamping of the encoder circular grating mounting base is achieved. The clamp is simple in structure, the automation degree of an encoder grating adjusting device is improved, and the clamp is stable in clamping and high in clamping precision.

Description

Technical field

[0001] The invention relates to the technical field of tooling fixtures, in particular to a grating fixture special for encoder circular grating eccentric adjustment. Background technique

[0002] Fixture refers to a device used to fix the processing object during the mechanical manufacturing process so that the processing object has the correct position, and then the fixed processing object is subject to construction or inspection.

[0003] Encoders are ideal angle sensors for automation equipment. Modern industry has an increasing demand for encoders, and the accuracy requirements for encoders are also getting higher and higher. When the grating is installed on the encoder spindle, the grating and the spindle rotation center are the same. The shaft degree has a great influence on the accuracy of the encoder; the fixture of the existing grating eccentric adjustment device has some shortcomings in the clamping efficiency and clamping accuracy. Therefore, the inventi...
