Description

TECHNICAL FIELD

[0001] The application relates to the technical field of milling mechanisms, and discloses an automobile part milling mechanism. BACKGROUND

[0002] Milling is a kind of mechanical processing method for cutting workpieces by using a rotary multi-blade cutter. During the milling process, the cutter rotates (as a main motion), the workpiece moves (as a feed motion), and the workpiece can also be fixed, in which case the rotating cutter needs to complete the main motion and the feed motion simultaneously. Through the relative motion between the cutter and the workpiece, the cutting edge of the cutter can cut into the surface of the workpiece, so that the material is removed.

[0003] Generally, the current automobile part surface milling mechanism usually adopts a workpiece fixed mode, in which the rotating cutter needs to complete the main motion and the feed motion simultaneously. The cutter route is set by a numerical control machine tool, and then the feed motion of the cutter is completed. The cutter rotation can be realized by using a rotary driving element, and the rotation speed can be controlled by a numerical control system. Therefore, the workpiece fixed mode and the rotating cutter which needs to complete the main motion and the feed motion simultaneously are the market mainstream.

[0004] However, a large amount of heat is generated during the milling of parts, because the cutter exerts force on the workpiece to cause plastic deformation during the milling process. When the metal material is subjected to extrusion and shearing actions of the cutter, the crystal structure inside the metal material will change in the form of slip and dislocation. This plastic deformation consumes a large amount of mechanical energy and converts it into internal energy of the material, resulting in temperature rise.

[0005] Therefore, a water cutter needs to be installed on both sides of the rotating cutter. The water cutter can generate a large amount of water to cool the rotating cutter and the workpiece, so as to ensure the normal milling.

[0006] Automobile part milling includes metal milling and non-metal milling. For plastic milling, special attention needs to be paid to the fact that the chip shape of plastic is different from that of metal, and is usually in the form of fragments or powder, which is easy to block the cutter and the cutting area, thereby affecting the normal processing. Therefore, most automobile part milling mechanisms are provided with a filtering structure.

[0007] In addition, the traditional milling device filters the washing water by using a filter screen and then recycles the water. However, this filtering structure is not suitable for non-metal milling, because the powder-shaped plastic is smaller than the filter screen aperture and can still enter the water recycling system, thereby causing damage and blockage of the water pump and the nozzle on the milling device, and finally affecting the service life of the entire device. In view of this, the application provides an automobile part milling mechanism to solve the above problems. INVENTION CONTENTS
