Description

[0001] This utility model relates to the field of machining loading equipment technology, and in particular to a loading mechanism for a CNC lathe. Background Technology

[0002] See appendix Figure 1 The image shows a pulley rim, which includes an inner hole and two conical surfaces. The inner hole is used to embed a bearing, and then the rim is riveted to the wheel body to form a pulley for a hanging rail. The two conical surfaces are used to reduce the contact area between the rim and the hanging rail, thereby reducing friction.

[0003] When processing the wheel rim, a steel pipe with the same diameter as the wheel rim is first processed into a blank of a set thickness on a saw. Then, the blank is processed into two conical surfaces on both sides using a CNC lathe. Currently, the loading of the blank onto the CNC lathe is done manually. Manual loading is labor-intensive and the process is cumbersome and inconvenient, resulting in low loading efficiency on the CNC lathe and affecting the processing efficiency of the wheel rim.

[0005] The lathe internal clamp structure includes the lathe, lathe housing, hydraulic cylinder, hydraulic rod, base, and other components. Its working principle involves the hydraulic system driving the hydraulic rod to move, which in turn moves the pull rod backward via the hydraulic connecting nut. This causes the expansion sleeve to open under the action of the pull rod's taper, clamping the inner wall of the workpiece. After machining, the hydraulic rod is moved forward by turning the handle on the adjusting wheel, releasing the expansion sleeve from the internal clamping force and thus releasing the workpiece.
