Preferably, one end of the buffer cylinder 12 in the buffer assembly is mounted on the grinding wheel rotating arm 13 , and the other end is fixed on the grinding wheel rotating shaft 9 . The beneficial effect is that: on the one hand, the design of the buffer assembly can provide effective protection to the rotating mechanism, and on the other hand, can also reduce the vibration of the equipment when the grinding head grinds the workpiece.

Preferably, the first cylinder 8 in the grinding head rotating assembly is installed on one side of the grinding wheel rotating shaft 9, and one end is fixed on the rack 10, and the rack 10 is realized by driving the gear installed on the grinding wheel rotating shaft 9. Alternation of two grinding heads. Beneficial effects: the grinding head rotation mechanism can quickly switch between different types of wire drawing wheels, reducing the number of grinding head replacements and improving work efficiency.

Preferably, the other end of the rack 10 is provided with a limiting plate 18 . The beneficial effect is that the limiting plate effectively prevents the rack from falling off from the rotating shaft of the grinding wheel during the rotation of the grinding head.

Preferably, a rib 17 is provided between the grinding wheel rotation column 16 and the grinding wheel rotation assembly mounting plate 19 . The beneficial effect is: the design of the rib plate effectively improves the stability of the grinding head, and relieves pressure for the load bearing of the rotating column of the grinding wheel.

Compared with the prior art, the beneficial effect of the present invention is that two grinding heads are designed, and through three rotating mechanisms, the grinding heads can be switched at will, and at the same time, the grinding heads can be accurately positioned to each point of the workpiece ;And there is a buffer assembly in the grinding head mechanism, which can protect the grinding head mechanism to a certain extent. This kind of grinding head mechanism not only saves the time of replacing the grinding head, but also improves the work efficiency, and the buffer mechanism makes the grinding head more durable. Durable, and there will not be too much vibration during the operation of the equipment.
