3D forming integrated on-line dynamic balance terminal

Abstract

The invention discloses a 3D forming integrated on-line dynamic balance terminal. A center taper hole is formed in the bottom of the integrated on-line dynamic balance terminal, at least two balance containing cavities of which the shapes are identical are evenly distributed in the integrated on-line dynamic balance terminal in the circumferential direction, and the balance containing cavities areseparated by containing cavity walls; at least two liquid guide grooves with equal distance are designed at the inner circle end face of the integrated on-line dynamic balance terminal in the axial direction, and the liquid guide grooves communicate with the corresponding balance containing cavities through ladder-shaped holes; at least two countersunk threaded holes are evenly distributed at same-radius circumference of the surface of cooperative table surface in the integrated on-line dynamic balance terminal; and the integrated on-line dynamic balance terminal is formed at one time adopting a 3D rapid forming technology, and parts required for precision are machined. According to the 3D forming integrated on-line dynamic balance terminal, extra cooperative connection is not required, the sealing performance of the balance containing cavities is greatly improved, the structure of a balance terminal is simplified simultaneously, and the weight of the balance terminal is reduced.

Description

technical field [0001] The invention relates to the technical field of online dynamic balancing of spindles, in particular to a 3D-formed integrated online dynamic balancing terminal. Background technique [0002] The spindle system is a key component of modern high-end CNC machine tools, and the processing effect of CNC machine tools depends largely on the performance of the spindle. Due to material, installation and manufacturing reasons, the spindle often has unbalance. When the spindle is working at high speed or even ultra-high speed, the unbalance will cause the vibration of the spindle to increase sharply, which seriously affects the processing quality of the machine tool. For the problem of excessive vibration of the machine tool spindle at high speed caused by the unbalanced amount of the spindle, the on-site dynamic balancing technology is now widely used to solve the problem, but the machine tool needs to be started and stopped continuously during the balancing pr...

Problems solved by technology

[0005] At present, the manufacture of the liquid-jet dynamic balancing terminal adopts the traditional machining manufacturing process, and the balance cavity of the balancing terminal needs good sealing performance, which makes it impossible to process the balancing terminal as a whole, and generally processes it into an inner The inner ring and the outer ring are assembled. This kind of machined balance terminal may cause the inner and outer rings to unscrew at high speed, which reduces the sealing performance of the balance cavity of the dynamic balance terminal; at the same time This kind of dynamic balance terminal has a complex structure, and there are a large number of redundant structures, which increase the quality of the dynamic balance terminal
