Problems solved by technology

However, the advantage of smooth swing mentioned in this prior patent application is actually only applicable to the initial stage of use, because this structural form of the suspension frame supported by bearings will generate strong friction between the components during work, which is very easy to Wear the bearing, and the worn bearing will inevitably cause the suspension frame to skew, which will seriously affect the measurement effect

Abstract

The invention relates to a XY axis rotational device, including the circular chassis, the rotating outer ring, the rotating inner ring, the bridge frame, the movable disk and the group roll component which is composed of a circular bead, two column concave and a snail. The bridge frame through vertical feet installs on the chassis, through its own fixed-hole the movable disk installs on the column of the rotating outer ring, the inner ring installs in the rotating center column, the rotating outer ring installs on the outer ring side of the rotating inner ring, the two group rolling components install between the rotating inner ring and the rotating central column, the other two group install between the rotating inner ring and the outer ring. the rolling component limited move between the rotating outer ring, the inner ring and the rotating center column, and each of their partial displacement all can be divided into the X and Y partial weight, and drive the work component of the movable disk to precise positioning; it has smooth swing, high positioning accuracy, reliability work and long use life, and has a strong practical and a broad market prospect.

Description

technical field [0001] The invention relates to a measurement auxiliary component, in particular to a universal gimbal that is suitable for use in automatic laser levels or engineering construction measurement operations and can accurately obtain horizontal reference lines and vertical reference lines under high-repeatability and high-sensitivity swings Bearing type XY axis free rotation device. Background technique [0002] The laser measuring instruments in the existing measuring devices are all supported by bearings and suspended on the body, and the laser transmitter is installed on the suspension in the form of a shaft, so that the laser transmitter can swing at multiple angles when it is working. , Project the laser beam to the required target position. Taiwan utility model patent No. M304654 "Suspension Mechanism of a Laser Measuring Instrument" patent specification discloses the laser measuring instrument with the existing structural form, which particularly emphasi...
