Numerical control grinding test machine

Abstract

The invention discloses a numerical control grinding test machine. A movable frame capable of moving transversely and longitudinally is mounted on an equipment machine frame. A rotation chuck used for clamping workpieces are mounted on the movable frame, and a rotary motor used for driving an abrasive disc to rotate is further mounted on the machine frame. The axis direction of a rotary shaft, the axis direction of the rotation chuck and the longitudinal movement direction of the movable frame are parallel to one another. A numerical control terminal is further included and connected with all the parts and controls all the parts to work. During operation, the to-be-tested workpieces are clamped and fixed through the rotation chuck, meanwhile, the rotary motor works to drive the abrasive disc to rotate, and then the movable frame moves transversely or longitudinally to conduct various grinding machining, so that actual grinding operation can be simulated more accurately, and the equipment test capacity is improved; and in addition, the test machine is provided with the numerical control terminal, the machining precision and working efficiency can be greatly improved through control of the terminal, and the grinding performance can be measured more accurately.

Description

technical field [0001] The invention relates to grinding equipment, in particular to a numerical control grinding testing machine for grinding workpieces or testing the grinding performance of coated abrasives. Background technique [0002] Grinding test machine is a kind of equipment used to test the grinding performance of abrasive tools, which mainly includes a test bench for placing the workpiece to be tested, and an abrasive tool for grinding the workpiece. Existing grinding test machines all fix the workpiece on a fixed test table, and then press the coated abrasive to the workpiece on the test table for grinding test. In this kind of grinding work, the distance between the workpiece and the coated abrasive is The distance is a single point contact, and the measured data is also a single value. However, in actual working conditions, the situation of single point grinding is extremely rare, and more is multi-track grinding involving the entire plane. The working process...

Problems solved by technology

This type of testing machine is also vertical grinding. Although the workpiece on it can move, its planar movement is composed of rotation and swing. If the grinding machine is to cooperate with its movement to form a specific trajectory, it needs an extremely complicated control program. And the coordination between the two is extremely high; in addition, the swing of the workpiece is controlled by the eccentric wheel, adjustable connecting rod, swing rod, and swing support shaft. The control accuracy of this structure is extremely low, and it is difficult to meet the high-precision requirements; In addition, the pressure control of this kind of testing machine is also controlled by the addition and subtraction of weights, which makes its control accuracy extremely low
