One part, the root of the groove is provided with an empty groove to prevent the support of the burrs at both ends of the rolling element, resulting in grinding waste, and the upper end of the groove is provided with a smooth transition chamfer to make the rolling element lead in and out smoothly.

The processing of the conical groove guide wheel is on a CNC lathe, and a special large-scale guide wheel outer end fixture is designed. First, the inner diameter of the tapered positioning hole is processed. The conical positioning hole of the conical groove guide wheel is divided into three stepped holes. The third hole is the main shaft matching hole, and the middle is the clearance hole. The main function of this structure is to improve the matching accuracy with the main shaft and achieve high-precision grinding; Accuracy performance, then continue to process the hollow hole at one end, and then process the hollow hole at the other end; then process the outer diameter guide groove based on the tapered positioning hole, and prepare the groove shape, lead, angle, and empty knife of the outer diameter guide groove CNC programs for grooves and chamfers. Compared with the ordinary processing of this guide wheel technology, the number of tools used is small, the cutting amount is reasonable, the resistance is small, and the precision is high. The high-precision guide wheel is installed on the equipment without adjustment, and the high-precision conical rolling body is directly ground, which reduces the processing cost and labor intensity of the workers, and improves the processing efficiency.

The utility model has the advantages of: compared with the prior art, it has the following beneficial effects: due to the application of the special groove-shaped guide wheel technology for grinding the outer diameter of the conical rolling body, the conical rolling body can realize the through-type grinding of the outer diameter, and the single grinding Cutting processing method. Workers are only responsible for placing materials on the guide plate and measuring the outer diameter. The operation is very convenient and the work efficiency is increased by more than 10 times. Due to the precision of the grooved guide wheel, the grinding quality of the outer diameter of the conical rolling body is improved. The perpendicularity between the outer diameter and the end face meets the precision requirement of 0.01mm.

Detailed ways

In order to gain a deeper understanding of the grooved guide wheel specially used for grinding the outer diameter of tapered rolling bodies, the description is as follows in conjunction with Figure 1, Figure 2, Figure 3, and Figure 4: See Figure 1 for the schematic diagram of the grooved guide wheel for grinding the outer diameter of tapered rolling bodies. The grinding wheel 1 is installed on the main shaft of the grinding wheel of the equipment, and the conical grooved guide wheel 4 is installed on the main shaft of the equipment opposite to the grinding wheel shaft, and rotates in the same direction. There is a rolling body guide plate 3 between the grinding wheel and the grooved guiding wheel, and the conical rolling body 2 On the guide plate 3, move forward with the conical groove guide wheel 4 through grinding wheel grinding. A lot of rolling elements can be placed on the guide plate. If the size is not ground after one pass, it can be passed again.

Figure 2. Schematic diagram of the shape of the special grooved guide wheel for grinding the outer diameter of the tapered rolling body. The outer diameter of the groove is in a spiral shape, similar to a left-handed large-lead tapered groove thread, which guides the conical rolling body to pass through the grinding wheel;
