Adjusting and positioning mechanism for parts at high-speed milling center

Abstract

The invention relates to an adjusting and positioning mechanism for parts at a high-speed milling center. The mechanism is composed of four screw mechanisms and two positioning pins, wherein the screw mechanisms are distributed at the side and rear of a reference part at the high-speed milling center; and the positioning pins are diagonally distributed on the reference part, and the positioning pins are connected with an adjusting component at the high-speed milling center. The mechanism has the advantages of simple structure and short manufacturing cycle, and the position is easy to control accurately during assembly adjusting without repeated adjusting.

Description

technical field [0001] The invention relates to a component adjustment and positioning mechanism, in particular to the adjustment and positioning of high-speed milling center adjustment components. Background technique [0002] The adjustment and positioning mechanism is generally designed between the basic components of the high-speed milling center, and its characteristics directly affect the accuracy retention, manufacturing cycle and cost of the machine tool. The precise positioning between the basic parts of the machine tool of existing products is generally realized by self-made T-shaped positioning keys and inclined plane keys, but practice has proved that the positioning method of the positioning keys has the following limitations: 1. The positioning accuracy is not easy to maintain for a long time, because The use of positioning keys inevitably requires machining of key grooves on the joint surface, resulting in a decrease in the stiffness of the joint surface, whic...

The precise positioning between the basic parts of the machine tool of existing products is generally realized by self-made T-shaped positioning keys and inclined plane keys, but practice has proved that the positioning method of the positioning keys has the following limitations: 1. The positioning accuracy is not easy to maintain for a long time, because The use of positioning keys inevitably requires machining of key grooves on the joint surface, resulting in a decrease in the stiffness of the joint surface, which often deforms under the action of cutting force and torque, thus losing its positioning function; 2. High production costs, T-shaped positioning keys The bevel key and the bevel key are all self-made parts, and the bevel with special angle needs to be processed; 3. The manufacturing cycle is long, and special tools are required to insert and pull out the positioning key during assembly and adjustment, and the position is not easy to accurately control and needs to be adjusted repeatedly
