Abstract

The invention relates to a sanding belt grinding device controlled by a programmable grinding force. The sanding belt grinding device consists of a control system, a comparing unit, a proportional servo element, a pressure cylinder, a grinding device and a detection unit. A practical grinding force detected by the detection unit and a command grinding force given by the control system are compared through the comparing unit; the difference value between the practical grinding force and the command grinding force is converted into control current or control voltage; and the control current or control voltage is converted and adjusted through the proportional servo element until practical grinding force controlled by the pressure cylinder is equal to the command grinding force, so that the practical grinding force drives the grinding device to grind. The sanding belt grinding device has the characteristics that: 1) the grinding force of the sanding belt grinding device is adjusted through a grinding force controlling and adjusting device in real time, so the practical grinding force grinds according to the command grinding force and the surface grinding quality of a workpiece is ensured; 2) the command grinding force can be realized through programming, so different ground workpieces or different parts of the same workpiece can be ground through different grinding forces; and 3)the grinding force of any ground point can be calculated through two-dimensional or three-dimensional interpolation operation according to the grinding forces of known key points of a given ground surface, and the grinding force of each ground point is in smooth transition, so the mutation phenomenon of the grinding force is not caused.

Description

technical field [0001] The invention relates to an abrasive belt grinding device, in particular to a flexible abrasive belt grinding device controlled by programmable grinding force, which is suitable for grinding complex curved surfaces such as steam turbine blades. Background technique [0002] Due to the special function and the increasingly higher requirements for product appearance in modern society, complex curved surfaces have been widely used in the machinery manufacturing industry. However, the finishing process of complex curved surfaces has always been a bottleneck process problem. [0003] In recent years, some patented technologies related to surface grinding have been successively introduced, such as: 200710019843.6 patented technology "Steam Turbine Blade Numerical Control Belt Grinder and Its Control Method" announced by the State Intellectual Property Office and 200820238217.6 patent technology "Steam Turbine Blade Numerical Control Belt Grinder "And other a...
