Straightening of the linear guide manufacturer's reference rail

(1). Using the space straightness measuring instrument to measure the straightness error of the horizontal and vertical directions of the guide rail, and calculate the offset of each measuring point relative to the second center line.

(2). Determine the linear basis based on the calculation results. Then, according to the offset of the corresponding point, the data is added for each place, and the guide rail is adjusted to make the straightness error in the two planes reach the requirement.

2. Parallel alignment of two linear guides

(1). Firstly, measure the straightness error of the linear guide and the relative coordinates (offset) of each measuring point (the two guide rails are only fixed to the lower mounting table); then, the two guides are measured by the level meter respectively. The difference between the starting point and the ending point (fastened between the joints), the height difference between the first and last points can be calculated by the difference between the viewpoint and the length. Use a dial gauge to measure the amount of change in the horizontal parallelism of the end and end points of the two rails.

(2). The alignment of the two guide rails is based on a guide rail that has been straightened. The adjustment reference line of the guide rail and the secondary center line of the reference guide rail (the yaw line reference of the reference guide rail) are parallel in the vertical direction, that is, the two ambition reference lines are coplanar (the two straight lines are linearly translated to one vertical line) Can be parallel in the face).
