Machining the shaft parts on the lathe, in order to ensure the concentricity of the shaft diameter of the whole shaft, it is generally a one-time clamping processing_complete, and the chuck is not loosened during the processing. Therefore, the length of the blanking is about 30mm longer than the length of the finished product, and the length is specially used for clamping. After the workpiece is processed, the part is cut with a cutter. So this length becomes a useless material.
1 technology and equipment <br> <br> feeding head without play transmission process is to take circular (diameter circular hole size, shape, depth, since as the case may be) at the clamping end of the shaft parts, with a special transmission triangular, four The pyramid is inserted into the transmission hole, and the tailstock is adjusted to clamp the workpiece by the thimble. Since the transmission pyramid is matched with the transmission hole to transmit torque and automatically correct the centering action, after the clamping, the lathe spindle can transmit the rotation to the workpiece, and the workpiece can be cut and the machining precision can be ensured. Each shaft of the process can save a piece of material of 0.2-15kg, and the weight of the thick shaft is larger, which is especially suitable for mass production. The materialless head processing technology can also be used in the finishing process after testing.
figure 1
As shown in Figure 1, the transmission pyramid is made of T8 or T9 steel. The pyramid head is processed and quenched. The hardness is up to HRC62-64. It is processed according to the IT standard 7-8 precision. It can be divided into large and medium according to the size of the workpiece. Small and various specifications, the size and taper are customized according to the situation, suitable for the processing of different diameter shafts. The method of use and the clamping method are shown in Figure 2.

A case where the aperture does not affect the structure and strength of the circular drive playing; 2 <br> <br> precautions Precautions To use this process, a transmission processing precision directly affect the pyramid _ stop the clamping member card status and precision Try to get bigger to increase the contact surface between the transmission pyramid and the transmission hole and the transmission torque; the thimble should not be loose during the cutting process. If the workpiece is loose or beating, the tailstock should be tightened in time; the transmission hole should be hit. The deviation of the center line of the shaft is minimized; this process is not suitable for the processing of the elongated shaft parts. Therefore, the thimble needs to be adjusted tightly during the clamping process, and the workpiece is subject to large axial force and is easily bent and deformed, so it is only suitable for the short axis. Processing.
