Precise balancing correcting method for super-hard abrasive grinding wheel

Abstract

The invention discloses a precise balancing correcting method for a super-hard abrasive grinding wheel. The method comprises the following steps: 1) drilling 3-6 uniformly distributed balancing holes on a same circumference of a base end face of the grinding wheel and arranging plugs; 2) testing unbalance amount of the grinding wheel on a balancing machine, thereby acquiring an initial gravity center position of the grinding wheel and unbalance torque of the grinding wheel; 3) establishing an X axis above the initial gravity center and circle center on the end face of the grinding wheel, symmetrically arranging the light point and initial gravity center of the grinding wheel about the center of the X axis, and confirming two balancing holes in the light point area of the grinding wheel, on the two sides of the X axis and closest to the X axis as first and second counterweight holes corrected by the grinding wheel; 4) respectively mounting opposite counterweights in the two counterweight holes. Practically, the mass on the opposite side of the gravity center area on the grinding wheel is greatly increased through the counterweights, so that the gravity center of the whole grinding wheel falls back to the axis position, and meanwhile, the counterweights are subdivided through a precision balance, so that the balance precision is increased.

Description

technical field [0001] The invention relates to a precision balance correction method for a superhard abrasive grinding wheel. Background technique [0002] The grinding wheel is a key part of the grinding process, but due to its manufacturing error, installation error, and uneven internal structure of the grinding wheel, it often causes the grinding wheel to be unbalanced, which in turn causes system vibration during the grinding process, reduces the quality of the grinding process, and even exists Hidden dangers in production safety. [0003] Grinding wheel balance is mainly divided into gravity balance and centrifugal balance. Gravity balance is also called static balance. It is usually on a horizontal balance frame and relies on the gravity of the grinding wheel to measure the unbalance. The static balance of grinding wheel is the most widely used, but the balance accuracy is low. Centrifugal balance is also called dynamic balance, which is to measure the unbalance acc...

Problems solved by technology

However, this method requires multiple inspections of the unbalance of the grinding wheel, multiple drilling or milling adjustments, the removal amount is difficult to control, the number of key points is different, the distribution is chaotic, and the depth of the heavy hole is not equal, which affects the appearance quality of the grinding wheel; and, because The weight of each grinding wheel is different, it is difficult to quantify the production, the influence of human factors is large, and the work efficiency is low

[0005] During the use of the grinding wheel, the balance correction of the grinding wheel on the ordinary grinding machine is mainly to use the single-sided balance weight method on the grinding wheel flange, but this correction method has the following defects in use: First, the center of gravity of the balance weight and the grinding wheel is on its axis If there is a distance in the direction, it is easy to generate a new force couple, which affects the overall balance accuracy of the grinding wheel; secondly, the contact mode between the balance block and the grinding wheel flange is mostly point contact or line contact, and there is a tendency for the balance block to slide; thirdly, the dovetail ring groove of the grinding wheel flange is uniform There is a channel for the balance block to enter and exit, which further reduces the balance accuracy of the grinding wheel
