Full-automatic pneumatic grinding machine and method thereof

Abstract

The invention discloses a full-automatic pneumatic grinding machine which comprises a rack and a dust collecting chamber. A grinding device is arranged in the dust collecting chamber; a material conveying device for inputting and outputting materials to the dust collecting chamber is arranged at the lower end of the grinding device; an adjustable fixture for clamping the materials is arranged on the material conveying device; an air blowing device for blowing away workpiece grinding ash is further arranged in the dust collecting chamber; and a powder dust outlet is formed in the bottom surfaceof the dust collecting chamber and is connected with a dedusting device. The full-automatic pneumatic grinding machine provided by the invention is high in adaptability, wide in use range, and capable of automatically dedusting a workpiece during grinding and being prevented from causing harm to a human body and an air environment; and secondly, a sufficient pre-tightening force or a precompression force can be ensured, and a cutter can strictly move vertically, so that the grinding size is accurate, and a grinding effect is greatly improved.

Description

technical field [0001] The invention relates to a material grinding device and method, in particular to a fully automatic pneumatic grinding machine and a method thereof. Background technique [0002] With people's requirements for fine processing of workpieces, workpiece grinding has gradually become an indispensable processing process. This process is mostly completed by mechanical arms or industrial robots. For example, the Chinese patent application publication number CN 106346337 A, the patent application number is The invention patent of 201510412296.2 discloses an automatic grinding device and method, which specifically discloses that it cooperates with a mechanical arm to grind workpieces. The automatic grinding device includes: a grinding tool, which is clamped at the end of the mechanical arm; , which has a feeding station, a grinding station and a receiving station set up in sequence; a material tank, which is arranged on the feeding station, and several workpiece...

AI Technical Summary

Problems solved by technology

[0003] Although the grinding precision of the mechanical arm is high, the mechanical arm has the inherent defect of relatively slow moving speed

In addition, the cost of equipment is high, and the cost of use and maintenance is high, which is difficult for small businesses to bear.

Moreover, there are at least the following problems with regard to its automatic grinding device: one, after the workpiece is polished, the grinding dust powder of its grinding will adhere to the surface of the workpiece, and the follow-up process cannot be directly used and easily damages the workpiece. In the air, it is harmful to the human body and is likely to cause dust explosion in the workshop; secondly, the pre-pressure of the tool is not enough or the tool is easy to deflect, and the processing error is large
