Abstract

A numerical control abrasive belt grinding machine comprises a computer NC device, a servo system, a grinding machine and a grinding head device. Wherein, the grinding machine is reconstructed from a common horizontal milling machine. The grinding head is fixed on an upper part of the grinding machine and comprises a bracket, an abrasive belt, an abrasive belt motion drive system and a protective shield. In addition, the servo system is composed of a drive device and an actuating mechanism. The actuating mechanism is consisted of actuating mechanisms enabling structures in the grinding machine to move linearly along direction X, Y and Z, make work-pieces to rotate along a shaft A. These actuating mechanisms can move independently under control the NC device and realize interlinked motion, which are driven by a stepping motor or a servo motor. The NC abrasive belt grinding machine not only grinds plane work-pieces but also those of curved surfaces and has the advantages of high processing precision, stable quality, simple structure and lower cost.

The turntable of fixation workpiece and top is installed on the workbench of grinding machine body, turntable and top coaxial line, their axis is the A axle, and turntable can be around the rotation of A axle under the drive of transmission mechanism, thereby workpiece fixed thereon also can rotate around the A axle.
Grinding head device is by support, and rack-mount drive motors, belt transmission pair, driving wheel, guide wheel, regulating wheel, regulating wheel regulating and controlling mechanism and active wheel are sleeved on abrasive band and protective cover formation on driving wheel, guide wheel, regulating wheel and the active wheel; Support is installed in the lathe bed top of grinding machine body and is connected with it, thereby grinding head device fixes, about can not doing with respect to workpiece, about and seesaw, the regulating wheel regulating and controlling mechanism is a hydraulic jack.
In order to improve transmission efficiency and precision, the member in the grinding machine body is made up of odontoid belt transmission and ball-screw nut transmission to straight-line transmission mechanism to, Z to, Y along X, making workpiece is gear driving pair around the transmission mechanism of A axle rotation.
The utility model has following beneficial effect:
But 1. because both independently moving of transmission mechanism, linkage again, but thereby both grinding flat work pieces, but grinding curve surface work pieces again.
2. adopt the reasonable assembly of computer numerical control device and servo-drive system, guaranteed machining accuracy effectively, improved the qualitative by force of working (machining) efficiency and product quality, with the processing of leaves is example, the blade profile surplus can be controlled in 0.1~0.2 millimeter, and printing opacity is 0.1~0.2 millimeter, and surface roughness can reach Percent ripple also is improved.
3. the grinding machine body is formed by existing non-numerical control horizontal milling machine transformation, has both reduced cost, and old-fashioned milling machine is fully used.
4. grinding head device is simple and reliable for structure, the wheel long service life.
