Method for adjusting base plates for high-accuracy machinery installation

Abstract

The invention relates to a method for adjusting base plates in high-accuracy machinery installation. The method is characterized by comprising the following steps: a) providing a plurality of base plates for the high-accuracy machinery installation, wherein each base plate (1) comprises a rectangular steel plate, a steel earhole plate (3) is welded on one short side of the rectangular steel plate, and the earhole of the earhole plate (3) is used for penetrating adjusting bolts (4); and welding the steel earhole plates (3) respectively on two long sides of the rectangular steel plate close to the other short side end of the rectangular steel plate, and drilling air exhaust holes respectively (2) at two sides of the middle point of the central line of the rectangular steel plate; b) placing the base plates (1) at corresponding foundation parts, driving the adjusting bolts respectively in the earhole positions of three earhole plates (3), and adjusting the scale height and horizontality at the upper surface of each base plate (1); and c) after secondary grouting, cutting a screw rod and a nut on the upper part of each earhole plate, rubbing down, hoisting the machinery device and carrying out accurate adjustment further.

Description

technical field [0001] The invention relates to a backing iron used in the installation of mechanical equipment, in particular to a method for adjusting a backing plate in high-precision mechanical installation. Background technique [0002] In order to adjust the elevation and levelness of mechanical equipment installation, flat shims and inclined shims are usually used. Flat pads are not commonly used due to the difficulty of adjustment and small adjustment room after the equipment is in place; inclined pads are widely used because they are easy to adjust, high in efficiency, and can meet the accuracy requirements of various equipment. Inclined pads must be used in pairs. That is to say, two pieces of slanting irons are used to tighten, and spot welding is firm to prevent loosening after the adjustment is completed. However, for machines with high installation accuracy and large operating vibration, during the adjustment process and after they are put into operation, the i...

Problems solved by technology

Flat pads are not commonly used due to the difficulty of adjustment and small adjustment room after the equipment is in place; inclined pads are widely used because they are easy to adjust, high in efficiency, and can meet the accuracy requirements of various equipment. Inclined pads must be used in pairs. That is to say, two pieces of slanting irons are used to tighten, and spot welding is firm to prevent loosening after the adjustment is completed. However, for machines with high installation accuracy and large operating vibration, during the adjustment process and after they are put into operation, the installation accuracy may be affected by the looseness of the slanting irons. The risk of major changes

[0003] Therefore, there are above-mentioned inconveniences and problems in the shim iron adjusting method of known mechanical equipment installation.
