Optic zooming CNC grinding machine, control system and control method

Abstract

The invention discloses an optic zooming CNC grinding machine, comprising a machining cabinet. The machining cabinet is provided with an XY axis regulation platform and an UV worktable for clamping a workpiece. The XY axis regulation platform is provided with a three-direction angle regulation device capable of regulating front and back and left and right positions. A rear bracket is arranged at the rear side of the machining cabinet. The rear bracket is provided with an optic zooming projection device with variable magnification times. A transmission light source is arranged at a position, exacting facing the optic zooming projection device, below the machining cabinet. The UV worktable is provided with a permanent magnetic table. The permanent magnetic table is positioned between the optic zooming projection device and the transmission light source, and the three-direction angle regulation device is provided with a cutting device. The optic zooming CNC grinding machine is high in grinding precision, convenient to adjust and has variable magnification times.

Description

technical field [0001] The invention relates to grinding equipment for processing workpieces, in particular to an optical zoom CNC grinding machine, a control system and a control method. Background technique [0002] At present, the existing CNC grinding machines have the following disadvantages: 1. The traditional optical grinding tool grinder controls the displacement and direction of movement of each cylinder by manually changing the flow and flow direction of each cylinder circuit by the operator, so that the oil in the two cylinders maintains a certain ratio Relationship, so that the grinding head on the grinding frame can obtain the corresponding curved track. Machining accuracy and efficiency are very low. 2. The optical tool grinding machine transformed by numerical control is not fully closed-loop controlled, the machining accuracy is unstable, and the error in machining cannot be compensated. 3. The optical tool grinder is horizontal. When clamping the workpiece...

Problems solved by technology

[0002] At present, the existing CNC grinding machines have the following disadvantages: 1. The traditional optical grinding tool grinder controls the displacement and direction of movement of each cylinder by manually changing the flow and flow direction of each cylinder circuit by the operator, so that the oil in the two cylinders maintains a certain ratio relationship, so that the grinding head on the grinding frame can obtain the corresponding curved track

Machining accuracy and efficiency are very low

2. The optical tool grinding machine transformed by numerical control is not fully closed-loop controlled, the machining accuracy is unstable, and the error in machining cannot be compensated

3. The optical tool grinder is horizontal. When clamping the workpiece, the operator needs to go to the side for clamping, which affects work efficiency

[0003] Although the existing workpiece processing machine tool optical projection equipment has 20 times lens and 50 times lens, it has the following defects: 1. When the 20 times lens needs to be replaced with a 50 times lens, the 20 times lens needs to be disassembled along the tooth hole. It can be used only after the 50x lens is put on it. It is inconvenient to operate. Dust will easily fall into the optical system during operation, which will affect the clarity of the optical path.

2. When processing parts with different sizes at both ends, the clarity of the transmitted light cannot be guaranteed, and the processing accuracy cannot be guaranteed

3. It is inconvenient to process when the upper and lower sides are irregular and the workpiece needs to be processed with a slope.
