Description

Technical Field

[0001] The present invention belongs to the technical field of CNC machining, and specifically relates to a CNC machining deburring auxiliary device, which is an auxiliary connection mechanism for realizing the connection of the CNC equipment spindle. It can be used to remove burrs on the surface of parts when a large number of burrs are generated on the parts after the CNC equipment is completed. The deburring auxiliary device is connected to the CNC spindle through a tool holder clamp for program control. Background Art

[0002] In the machining industry, burrs on parts are a common problem in the manufacturing process. Burrs on parts refer to small residues formed on cutting edges, extrusion holes or surfaces due to cutting or extrusion during metal or plastic processing, stamping, casting, molds, etc. These burrs not only affect the appearance and dimensions of the parts, but also have a significant impact on the quality and performance of the parts during use. There are many ways to remove burrs on parts, such as scrapers, assorted files, sandpaper, polishing machines, etc. Manual deburring mostly uses scrapers, assorted files, etc. Due to the differences in operating skills of operators, the final deburring effect is also different, resulting in poor dimensional accuracy and consistency in part appearance, and extremely low production efficiency. Using a polishing machine for deburring, the burrs are not removed thoroughly, and may even affect the appearance and color of the parts.

[0003] Therefore, in response to the above situation, a CNC machining deburring auxiliary device was designed. The device does not affect the dimensional accuracy and appearance of the parts, greatly improving the production efficiency. The device has simple process, low cost, simple, convenient, fast operation and good practicality. Summary of the Invention

[0004] The present invention aims to develop a numerical control machining deburring auxiliary device with a simple structure, high reliability, safe use and high production efficiency, characterized in that the numerical control machining auxiliary device comprises a bowl-shaped steel wire wheel (1), a connecting shaft (2), a locking nut (3) and an anti-rotation screw (4). The connecting shaft (2) connected to the spindle tool holder of the numerical control equipment is designed as a threaded step shaft structure, the threaded shaft is M16x2 and is made of steel 45GB / T699-2015 material. The connecting shaft (2) and the bowl-shaped steel wire wheel (1) are assembled, and a wrench and a locking nut (3) are used to lock the connecting shaft (2) and the bowl-shaped steel wire wheel (1). The anti-rotation screw (4) connects the locking nut (3) and the bowl-shaped steel wire wheel (1) to prevent the device from separating when the numerical control equipment is running at high speed.

[0005] This CNC machining deburring auxiliary device can be used on general CNC equipment such as vertical machining centers and horizontal machining centers. It can also automatically polish parts by replacing polishing wheels of different materials through a connection device. The device has a simple processing process, low cost, and strong operability.

[0008] The present invention provides a universal connection mechanism for connecting with the spindle of CNC equipment. Figure 1 The schematic diagram of the CNC machining deburring auxiliary device is shown.

[0009] First, insert the connecting shaft (2) into the center hole of the bowl-shaped wire wheel (1), and then use the locking nut (3) to screw the M16x2 threaded connection part on the connecting shaft (2) until there is no gap. After the bowl-shaped wire wheel (1), the connecting shaft (2), and the locking nut (3) are assembled, use the anti-rotation screw (4) to penetrate the locking nut (3) and the coaxial threaded hole of the bowl-shaped wire wheel (1) for threaded connection. The universal tool holder of the CNC machining equipment is used to connect and lock the connecting shaft (2) before use.
