The shaft sleeve is generally matched with the rotating shaft and used for reducing the friction force applied to the rotating shaft in the rotating process, so that on one hand, the energy loss can be reduced, and on the other hand, the overheating of mechanical parts can be effectively avoided. In order to make the motion cooperation of the shaft sleeve and the shaft better, an oil groove is normally arranged on the inner wall of the shaft sleeve, so that the purposes of lubricating and accumulating lubricating oil are achieved.
Chinese patent with publication number CN202591698U discloses a shaft sleeve oil groove processing device, which comprises a frame, a servo motor I, a tool rest, an upright post, a screw I, a cutting mechanism, a three-jaw chuck, a circumferential feeding device, a servo motor II, a control panel, a workbench, a horizontal guide rail and a screw II. Wherein, the workbench is arranged on the frame through a horizontal guide rail; the tool rest is arranged on a vertical guide rail of the upright post; the upright post is fixedly connected with the frame; the circumferential feeding device is fixed on the workbench; the three-jaw chuck is fixed on the circumferential feeding device; the servo motor II is connected with the workbench through a lead screw II; the servo motor I is connected with the tool rest through a lead screw I; the cutting mechanism is fixed on the tool rest; the control panel is fixed in front of the frame.
The cutting mechanism of the shaft sleeve oil groove processing device is small in size, and various complex oil grooves such as a spiral type oil groove and a cross type oil groove can be processed on the inner wall of a part by changing feeding parameters, so that the technical problems that the oil groove of the existing small-diameter shaft sleeve part is difficult to process and the processing shape is single are solved.
Taking the splayed oil groove as an example, when the inner wall of the shaft sleeve is cut, the circumferential feeding device always drives the three-jaw chuck to rotate so as to drive the workpiece to rotate. Meanwhile, the servo motor II drives the screw rod II to rotate, so that the workbench moves on the horizontal guide rail to drive the three-jaw chuck to translate, and the horizontal feeding action of the workpiece is completed. The workpiece completes one reciprocating motion, and the splayed oil groove can be machined and formed.
Because the shaft sleeve is of a hollow thin-wall structure, when the pressure exerted on the shaft sleeve by the three-jaw chuck is overlarge, the shaft sleeve is easy to collapse and deform, and the shaft sleeve is directly damaged. Therefore, the pressure exerted on the sleeve by the three-jaw chuck is limited, and the friction force between the three-jaw chuck and the sleeve has an upper limit. When the pressure between the tool bit and the shaft sleeve is larger than the friction force, the shaft sleeve can move relative to the three-jaw chuck, the shape of the oil groove is damaged, and the machining quality is greatly influenced.
