Numerical control polishing machine

Abstract

The invention discloses a numerical control polishing machine. The numerical control polishing machine comprises a four-axis workpiece shifting device and a rotary polishing head, wherein the four-axis workpiece shifting device comprises a stand column, a Y-axis sliding seat, an X-axis rotary arm, a Z-axis rotary arm, an A-axis rotating work bench, a Y-axis driving assembly, an X-axis driving assembly, a Z-axis driving assembly and an A-axis driving assembly; and the rotary polishing head is provided with a main polishing mechanism, the main polishing mechanism comprises a main grinding wheel assembly, a main rotating arm and a main grinding wheel vertical/horizontal transforming assembly, the main grinding wheel assembly is mounted on the main rotating arm, and the main grinding wheel vertical/horizontal transforming assembly drives the main rotating arm to rotate, so that the rotary polishing head transforms at any angle in the vertical direction and the horizontal direction, and accordingly, a workpiece on the A-axis rotary work bench is polished in an omnibearing manner. The numerical control polishing machine can automatically polish a casting, effectively removes burrs and flashing of the casting and is efficient, environment-friendly, safe and simple and convenient to operate, the labor intensity is reduced, and the polishing quality is improved.

Description

technical field [0001] The invention relates to a numerical control grinding machine, which is a high-efficiency equipment for removing flash and burrs of casting parts with complex shapes. Background technique [0002] At present, in the foundry industry, the flash and burr removal of parts with complex shapes is usually done with grinders and other hand-held tools; some use special equipment to complete; only a few countries in the world produce high-quality CNC grinding machines. [0003] The manual method has the following disadvantages: [0004] 1). The operation is dangerous and labor-intensive, which is harmful to the body of workers. [0005] 2). Noisy, dusty, serious environmental pollution. [0006] 3). The consistency of grinding quality of large batches of castings cannot be guaranteed. [0007] 4). A lot of labor is required. [0008] 5). The grinding efficiency of castings with complex shapes is low. [0009] Special equipment generally uses several power ...

AI Technical Summary

Problems solved by technology

[0004] 1). The operation is dangerous and labor-intensive, which is harmful to the body of workers

[0005] 2). Noisy, dusty, serious environmental pollution

[0006] 3). The consistency of grinding quality of large batches of castings cannot be guaranteed

[0007] 4). Need to use a lot of labor

[0008] 5). The grinding efficiency of castings with complex shapes is low

[0009] Special equipment generally uses several fixed-direction power heads to process the parts in combination. The degree of automation is not high, the adjustment is difficult, the flexibility is poor, and it is difficult to adapt to different sizes and different types of parts at the same time.

[0010] Although imported CNC grinding machines can do this work well, they are expensive and inconvenient for maintenance services; although some domestic companies have developed CNC grinding machines, there is still a big gap in performance and level. Enter the practical stage
