Problems solved by technology

[0002] Since the milling cutter itself requires high precision and has different outer diameters, it is difficult to achieve high-precision continuous indexing and automatic clamping. At present, it uses traditional mechanical tools on ordinary four-axis / five-axis tool grinders. The CNC turntable implements continuous rotation indexing. The loading and unloading of the bar is completed by manual fixing. The time for manual clamping and correction takes about 10S. The labor intensity of manual loading and unloading is too large and the efficiency is low due to the traditional mechanical CNC turntable. Worm gear or gear transmission mode, this kind of turntable has slow response speed, there is a gap when it rotates forward and reverse, and the mechanism is complex and easy to wear

Embodiment Construction

[0015] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments. Such as figure 1 As shown, a special direct-drive turntable for a tool grinder includes a direct-drive turntable 1 and an automatic broach mechanism 2 installed inside the direct-drive turntable; the direct-drive turntable includes: a base 3, a main shaft 5, a stator 4, and a rotor 9 and other related components. Such as figure 2 , a hole is reserved on the base 3, the stator 4 is fixed on the base 3 through a locking piece, the main shaft 5 passes through the center of the base 3 and is jointly supported by the front end bearing 7 and the end bearing 8, and the outer diameter of the main shaft 5 is threaded , the fixed nut 14 is locked on the thread at the tail end of the main shaft 5, and the end bearing 8 is pressed, so that the runout of the end face and the inner hole of the positioning stop 6 on t...

Abstract

The invention relates to the technical field of tool grinding machines, in particular to a direct drive rotating table special for a tool grinding machine. The direct drive rotating table comprises adirect drive rotating table and an automatic broach mechanism arranged in the direct drive rotating table. The direct drive rotating table comprises a base, a main shaft, a stator, a rotor, a rotatingseat and a fixed seat. The automatic broach mechanism comprises a piston cylinder, a piston, a broach rod, an air cylinder, a clamping claw and a tool handle seat. By means of the device, automatic bar loosening and clamping are achieved, and repeated labor force is reduced.
