CYLINDRICAL PIN ROTARY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/047318
Kind Code:
A1
Abstract:
A cylindrical pin rotary device (100), being used for rotating a cylindrical pin (200) the surface of which is to be processed; the cylindrical pin rotary device (100) comprises a housing (20), and a rotary core (30) and a ratchet mechanism (50) which are provided in the housing, the ratchet mechanism (50) comprising a ratchet (52) sleeved on the rotary core (30), an operating member (55) rotatably provided in the housing (20) and partially extending out of the housing (20) and a pawl (57) rotatably provided on the operating member (55), the pawl (57) cooperating with the ratchet (52), one end face of the rotary core (30) away from the operating member (55) being provided with a mounting hole (31) at the center thereof along the axial direction for mounting the cylindrical pin (200), each time pressing the operating member (55), the pawl (57) being driven to push against the ratchet (52) to rotate for a certain distance, thereby driving the rotary core (30) to rotate for a corresponding distance, facilitating performing surface processing, such as polishing, on the cylindrical pin (200). The cylindrical pin rotary device not only has a simple structure and low manufacturing cost, but also is easy to use.
