Description

Technical Field

When the transmission shafts in these mechanical transmission equipment are processed, they all need to be milled by milling equipment; for example, Chinese patent (CN215280026U) discloses a milling equipment for precision transmission shaft of an engine, including a milling machining center and a clamping chuck in the milling machining center, two groups of pressure shells are installed on both sides of the clamping chuck, and each group of pressure shells is distributed in a ring array, and the lower ends of the pressure shells are installed with top columns, and the lower ends of the top columns are installed with support plates, and the lower ends of the support plates are installed with arc-shaped copper plates. The technical solution is to fix the transmission shaft by air pressure, but the milling equipment has the following shortcomings: since the transmission shaft is fixed by air pressure, when the gas connecting cavity leaks, the transmission shaft will loosen, affecting the fixing effect, thereby causing insufficient stability to the subsequent milling process;

[0003] In view of this, a Chinese patent (CN116422953B) discloses a port machinery transmission shaft processing and milling equipment, which utilizes a rotating ring to rotate so that multiple arc plates simultaneously approach the transmission shaft body to achieve clamping and fixing thereof, and during the clamping process, the arc plate moves a certain distance to drive the side top block to move out of the side groove and abut against the side wall of the receiving groove, thereby reinforcing the position of the moving column in the receiving groove, effectively improving the fixing effect of the transmission shaft body in the mounting sleeve;

[0004] However, the above scheme still has the following problems: when the connecting gear is driven by the rotating ring to drive the moving column to move in the receiving groove, since the connecting gear only cooperates with one side of the moving column, the moving column is easily subjected to uneven force, resulting in a slight offset in the moving process of the moving column, and the elastically connected arc plate further makes the clamping unstable, and the transmission shaft body is subjected to force and positional offset during milling, affecting the precision machining of the transmission shaft; and during the movement of the arc plate, the side top block is driven to abut against the side of the receiving groove for reinforcement, and the moving column cannot continue to move when the side top block abuts against the side of the receiving groove, further limiting the clamping range of the entire structure.

A method for operating the milling equipment for machining a transmission shaft according to claim 1, characterized in that: The working method comprises the following steps: placing a transmission shaft to be processed into a clamping cavity (52), starting a rotating motor (512) to drive a rotating gear (511) to rotate, the rotating gear (511) drives a first rotating ring (56) to deflect, the first rotating ring (56) drives a second rotating ring (57) to deflect synchronously via a connecting rod (58), the synchronously rotating second rotating ring (57) and the first rotating ring (56) respectively drive a first transmission gear (542) and a second transmission gear (544) to rotate, thereby driving a first regulating gear rod (541) and a second regulating gear rod (543) to rotate, the first regulating gear rod (541) and the second regulating gear rod (543) to rotate synchronously in opposite directions. The tooth plate (551) is driven to move, the tooth plate (551) drives the sliding base (552) to slide in the sliding groove (53), the sliding base (552) drives the clamping plate (553) to move toward the center of the clamping cavity (52), and the transmission shaft to be processed is clamped. In the clamping process, the buffer pad (556) preferentially contacts the axial surface of the transmission shaft. After the clamping is completed, the driving motor (61) is started to drive the driving gear (62) to rotate, and the driving gear (62) drives the mounting plate (51) to rotate. After the rotation, the position of the mounting frame (2) is adjusted by the moving component (3), and then the position of the milling component is adjusted to perform milling processing on the transmission shaft to be processed.
