Description

Technical Field

[0001] The utility model relates to the technical field of guide sleeve device equipment, in particular to a synchronous rotary guide sleeve device. Background Art

[0002] The existing Swiss-type CNC lathes generally use fixed guide sleeves. The so-called fixed means that the guide sleeve is fixed and the workpiece moves. Friction will be generated between the moving parts and the fixed parts during the movement, and the magnitude of the friction will increase with the roughness of the workpiece surface and the size of the rotation speed. Especially when using fixed guide sleeves to process alloy steel, stainless steel and other materials that are not easy to cut, problems such as adhesion and burning will occur. Especially in this field, the processing of long and thin workpieces is the same as the traditional processing of short and thick workpieces. During the processing, the workpiece is required to be stable and without jumping. It is necessary to add support to the proximal end of the workpiece. After adding support, there will be friction, resulting in inconsistent rotation speed of the workpiece. There is also torque, and it will increase with the roughness of the workpiece and the size of the rotation speed, which limits the rotation speed of the spindle and the range of processing to a certain extent.

[0003] The application number is CN200820094175.3, which discloses a synchronous rotary guide sleeve device, including a transmission shaft, a spindle housing, a spindle, a guide sleeve outer wall, a guide sleeve support frame, and a high-speed rotary bearing. The spindle speed is transmitted to the free rotary guide sleeve through the first synchronous belt, the second synchronous belt, and the transmission shaft, so that the free rotary guide sleeve and the spindle reach the same speed. Thus, the free rotary guide sleeve and the raw material or workpiece rotate at the same speed, and the friction between the raw material and the guide sleeve is minimized.

[0004] A synchronous rotating guide sleeve device disclosed in the above document has the following defects: when a workpiece is inserted into the guide sleeve for processing, the rotation of the rotating structure will drive the guide sleeve and the workpiece to rotate. If the connection between the guide sleeve and the rotating structure is not firm enough, the processing quality of the workpiece on the guide sleeve will be affected and reduced, and in severe cases, the guide sleeve and the workpiece may be deflected and fall due to the rotation of the rotating structure.

[0005] It can be seen from this that the existing synchronous rotary guide sleeve device does not have the function of being fastened and connected to the rotary structure, and it is necessary to improve the existing deficiencies and provide a function that enables the device to be fastened and connected to the rotary structure.
