AI Technical Summary

Problems solved by technology

Affected by factors such as uneven force and residual stress during processing, small-sized rod products are prone to straightness errors, which will eventually affect system performance and accuracy during use. Radial runout will occur when the hole is cut, which will affect the machining accuracy of the round hole and the life of the drill bit

Abstract

The invention discloses a high-precision rotation driving device. The device comprises a base and a rotation driving component, wherein the rotation driving component is installed on the base; the rotation driving component comprises a motor and a rotation driving mechanism driven by the motor; and the rotation driving mechanism comprises a rotation gear, a first driving wheel an a second drivingwheel, all of which are combined together, wherein the rotation gear, the first driving wheel and the second driving wheel cooperate with one another to be used for tightly pressing a small-sized barproduct placed on the base and driving the small-sized bar product to rotate, and the first driving wheel and the second driving wheel can adjust relative clearance according to the diameter of the small-sized bar product. In this way, the rotation driving precision of the small-sized bar product can reach a submicron level, and therefore the linearity error detection precision of the small-sizedbar product can be ensured.

Description

technical field [0001] The invention relates to the field of precision detection equipment, in particular to a high-precision rotary drive device. Background technique [0002] High-precision small-size rod products are widely used in high-end manufacturing as parts or tools, such as micro drills, high-precision pins, etc. Affected by factors such as uneven force and residual stress during processing, small-sized rod products are prone to straightness errors, which will eventually affect system performance and accuracy during use. Radial runout will be generated when it is used, which will affect the machining accuracy of the round hole and the life of the drill bit. This requires high-precision measurement of the straightness of small-sized rod-shaped products to test the processing capability of small-sized rod-shaped product processing equipment and ensure the quality of small-sized rod-shaped products. During detection, the small size rod is driven to rotate by the rot...
