Numerical control device for flexible constant-pressure grinding of top part of cylinder block casting

Abstract

The invention discloses a numerical control device for flexible constant-pressure grinding of the top part of a cylinder block casting. The numerical control device comprises a base; the base is provided with an X-axis sliding table; the X-axis sliding table is provided with a Y-axis sliding table; the Y-axis sliding table is provided with a numerical control rotary table; the numerical control rotary table is fixedly provided with a to-be-ground workpiece; the base is further provided with pillars; a cross beam is arranged on the pillars; the cross beam is provided with pulleys; a pull rope passes across the pulleys; one end of the pull rope is connected with a weight; the weight is put on a weighing sensor; the weighing sensor is arranged on the pillar through a sliding table; the otherend of the pull rope is connected with a grinding head sliding table; the grinding head sliding table is provided with a grating ruler; the grinding head sliding table is fixedly provided with a grinding head motor; an output shaft of the grinding head motor is connected with a grinding head; and the grinding head is located above the to-be-ground workpiece. The device disclosed by the invention is controllable in grinding pressure, is capable of realizing constant-pressure grinding, has a stable grinding process and is high in quality; and a grinding allowance can be set, so that even if castings of the same workpieces are greatly different in size, the same grinding allowance can be guaranteed.

Description

technical field [0001] The invention relates to a grinding device, in particular to a flexible constant pressure grinding numerical control device. Background technique [0002] In mechanical processing, it is often necessary to grind some parts. There are many types of existing grinding equipment with different functions. Although the grinding accuracy is high, most of them have complex structures, low grinding accuracy, and poor adaptability. For some surface shape features Complicated parts are difficult to grind in place, and because the grinding wheel itself is rigid, although it can quickly cut off the protrusions and dross on the surface when it is in contact with the workpiece, it is easy to lose the workpiece, resulting in excessive contact friction. And cause the workpiece surface to be absent, especially for the slightly less workpiece of hardness, its grinding effect is very bad, and emery wheel also causes its contact area is little when grinding because of its ...

[0002] In mechanical processing, it is often necessary to grind some parts. There are many types of existing grinding equipment with different functions. Although the grinding accuracy is high, most of them have complex structures, low grinding accuracy, and poor adaptability. For some surface shape features Complicated parts are difficult to grind in place, and because the grinding wheel itself is rigid, although it can quickly cut off the protrusions and dross on the surface when it is in contact with the workpiece, it is easy to lose the workpiece, resulting in excessive contact friction. As a result, the surface of the workpiece is missing, especially for workpieces with a slightly lower hardness, the grinding effect is very bad, and the grinding wheel also has a small contact area during grinding due to its rigid contact, and the grinding efficiency is low.
