Three-axis aligning and leveling type rotary table

Abstract

The invention relates to a three-axis aligning and leveling type rotary table which comprises a base and a work table, wherein a clamp ring sleeve is arranged on the periphery of the base under the work table; a linkage ring is arranged in the clamp ring sleeve; a center steel ball is arranged between the linkage ring and the base; through holes are vertically formed in the linkage ring; a vertical tensioning mechanism is arranged in the through holes; two aligning mechanisms and a leveling mechanism are arranged between the base and the work table; one aligning mechanism is arranged in the X-axis direction, and the other aligning mechanism is arranged in the Y-axis direction; and the included angle between the leveling mechanism and each of the two aligning mechanisms is respectively 135degrees. The three-axis aligning and leveling type rotary table has the advantages that the structure is reasonable; a three-axis regulation method is used, so that the operation is more convenient; the work efficiency is improved; the two aligning mechanisms are respectively in charge of the motion in the X-axis direction and the Y-axis direction without the interference with each other; the leveling mechanism uses a hollow cylindrical roller to be in linear contact with the work table, so that the contact force of the vertical motion of the work table is increased; and the leveling sensitivity of the work table is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a three-axis self-aligning and leveling turntable. Background technique [0002] At present, the roundness measurement of rotary parts at home and abroad needs to be completed by a roundness meter. When measuring the workpiece, the roundness meter needs to adjust the eccentricity and inclination of the workpiece. When measuring high-precision rotary parts, the geometric axis of the measured workpiece does not coincide with the rotary axis and there is an angle, which leads to the nonlinearity of the data sampling model. If the sampling data is still calculated according to the data points of the theoretical circle, it will cause errors. . Therefore, the adjustment accuracy of eccentricity and inclination directly affects the measurement accuracy of the roundness meter. [0003] A three-axis self-aligning and leveling turntable is used to adjust the eccentricity an...

Problems solved by technology

[0003] A three-axis self-aligning and leveling turntable is used to adjust the eccentricity and inclination of the workpiece to be measured. It is divided into two types: automatic and manual. The automatic three-axis self-aligning and leveling turntable has relatively high adjustment efficiency and accuracy. , but the cost is high, the structure is complex, and the maintenance technical requirements are high, most manufacturers will not give priority to it; a manual three-axis self-aligning and leveling turntable has the advantages of low cost and simple structure, but the structure is heavy and the precision is low, so it is not suitable Suitable for high-precision rotary parts

[0004] In addition, the adjustment accuracy and efficiency of the roundness meter vary with the skill of the operator and can easily affect the reliability of the measurement results
