Driving mechanism for measuring machine supporting column

Abstract

The invention discloses a driving mechanism for a measuring machine supporting column. The driving mechanism is arranged on one side of a marble working table and used for driving the supporting column to move and comprises a motor. The motor is connected to the marble working table through a motor base and is connected with a synchronous belt through a retarding mechanism, the synchronous belt is connected with the supporting column, and a horizontal adjustment mechanism and a vertical adjustment mechanism are arranged at two ends of the synchronous belt respectively. The synchronous belt has the advantage of high loads of lead screw transmission, is high in transmission precision and small in work noise, simultaneously has sufficient flexibility, can reduce impact caused by mechanism inertia in starting or braking, and is suitable for being used in an air floating mechanism.

Description

technical field

[0001] The invention relates to a driving mechanism in the field of three-coordinate measuring machines, in particular to a driving mechanism for a pillar of a measuring machine. Background technique

[0002] The driving mechanism for driving the pillar of the three-coordinate measuring machine generally has the following forms. 1. Screw drive, which is suitable for high load transmission, but the rigidity is too strong, and the screw is easy to deform after long-term use, affecting the transmission accuracy, and requires frequent maintenance. maintain. 2. Rack and pinion, with loud noise and strong rigidity during operation, is not suitable for use in air-floating mechanisms and requires frequent maintenance. Contents of the invention

[0003] The purpose of the present invention is to overcome the above problems in the prior art, and provide a driving mechanism for the pillar of the measuring machine, which has high transmission precision, low working no...
