Description

Technical Field

[0001] The utility model relates to the technical field of sleeve feeding mechanisms, and more specifically to a sleeve feeding mechanism for a tailstock of a numerically controlled roller grinder. Background Art

[0002] During the machining process of CNC roll grinder, the performance of the tailstock sleeve feed mechanism plays a vital role in the machining quality and efficiency of the roll. The sleeve is slidably mounted on the tailstock body, and the feed drive device is used to drive the sleeve to feed on the tailstock body to achieve functions such as supporting and adjusting the position of rolls of different sizes.

[0003] After searching, the Chinese patent with announcement number CN218397609U discloses a tailstock sleeve feeding mechanism for a CNC roll grinder. Although the equipment can provide a certain clamping effect for the workpiece, it can only drive the sleeve to extend outward by driving the screw to rotate through the driving mechanism. However, when clamping the roll, only the three-jaw chuck on the CNC grinder rotates, while the top does not rotate. The workpiece will generate friction relative to the rotation of the top, which increases the rotation resistance of the roll and affects the service life of the top. By forming two soft connections at the same time through two rotation points or understanding the soft connection as a buffer part, the sleeve and the push rod can be turned, instead of causing friction and wear of the top as the roll rotates as in the prior art, which affects the service life of the top, and the two soft connections can be used to avoid the top and the roll from forming a hard connection.

[0004] The tailstock sleeve feeding mechanism of the CNC roll grinder usually adopts a single transmission method, relying only on the motor to drive the lead screw for feeding movement. Although a certain accuracy requirement can be achieved when relying solely on the motor and lead screw transmission for feeding, the speed is slow when making rapid adjustments. When it is necessary to frequently change rolls of different specifications for processing, each adjustment of the tailstock sleeve position takes a long time, which seriously affects production efficiency.

[0026] As attached Figure 4-5 As shown, the precise feeding mechanism includes a motor 11, which is fixedly mounted on one side of the moving platform 5. A threaded rod 12 is fixedly connected to the output end of the motor 11. One end of the threaded rod 12 passes through the moving platform 5 and extends into the inside of the groove 6. The threaded rod 12 is rotationally connected to the moving platform 5. A threaded groove 13 is provided on one side surface of the connecting column 7.
