The honing head provided by the embodiment of the application is described in detail below by means of specific embodiments and application scenes thereof with reference to the accompanying drawings.

As shown in fig. 1 to 2, the embodiment of the present application provides a honing head including a honing head body 100, an oilstone plate 200 and an oilstone 300.

The honing head body 100 is for coupling with a honing machine spindle, and the honing head body 100 may include a base 110 and a chuck 120, the base 110 being coupled with the chuck 120, wherein the base 110 may be coupled with the honing machine spindle, and the chuck 120 may be for mounting the oilstone plate 200. The honing head main body 100 can be connected with a honing machine main shaft through the hanging pin 800, the honing machine main shaft expansion and contraction mechanism can push the cone core 900 to reciprocate, the cone core 900 is contacted with the expansion pin 1000 through the conical surface of the cone core 900, and then the expansion pin 1000 drives the oilstone plate 200 to expand along the radial direction of the honing machine main shaft, so that honing processing by using the oilstone 300 is realized.

The oilstone plate 200 may be clamped to the chuck 120 of the honing head body 100. The oilstone slab 200 may include an oilstone substrate 210 and an oilstone base plate 220, the oilstone substrate 210 and the oilstone base plate 220 being of a split type structure, wherein the oilstone substrate 210 is connected with the honing head body 100, and the oilstone base plate 220 is detachably connected with the oilstone substrate 210. The chuck 120 is provided with a clamping groove, and the oilstone substrate 210 is arranged in the clamping groove. The whetstone 300 is connected to the whetstone base 220. The whetstone 300 may be bonded to the whetstone base 220. The honing head may further include a pressing cover 1100, the pressing cover 1100 being connected to the honing head body 100, and the pressing cover 1100 being located at a side of the honing head body 100 facing away from the main shaft of the honing machine. The gland 1100 may protect the whetstone 300 to prevent other components from damaging the whetstone 300 when the honing head is not in operation.

In the embodiment of the present application, the honing head may be detached from the honing machine spindle first when the oilstone 300 wears or processes parts of different apertures. Since the oilstone slab 200 includes the oilstone substrate 210 and the oilstone base plate 220, and the oilstone substrate 210 and the oilstone base plate 220 are of a split type structure, when the oilstone 300 or the oilstone base plate 220 needs to be replaced, the oilstone base plate 220 can be directly detached from the oilstone substrate 210 without having to detach the entire oilstone slab 200. The volume and weight of the oilstone slab 220 are smaller than those of the entire oilstone slab 200, and thus, it is easier to disassemble and install, so that replacement time can be saved, and labor intensity of operators can be reduced.

In an alternative embodiment, the honing head may further comprise a threaded connection by which the whetstone base 220 is connected to the whetstone base 210. And the time and labor are wasted when the threaded connection is disassembled. Thus, in an alternative embodiment, the honing head may further include an elastic member 400, the whetstone base 220 is connected to the whetstone base 210 by the elastic member 400, and the elastic member 400 surrounds the whetstone base 210 and the whetstone base 220. When the whetstone base plate 220 is worn or parts with different apertures need to be processed, namely, the whetstone base plate 220 is disassembled, the elastic piece 400 can be firstly removed, and the whetstone base plate 220 can be disassembled from the whetstone base plate 210; when the oilstone baseplate 220 needs to be installed, the elastic piece 400 is sleeved on the oilstone baseplate 210 and the oilstone baseplate 220. It can be seen that the connection of the whetstone base plate 210 and the whetstone base plate 220 by the elastic member 400 saves more time and effort in installation and removal. The elastic members 400 may be springs, and the number of the elastic members 400 may be two, and the two elastic members 400 are respectively disposed at two sides of the oilstone base plate 220, thereby being beneficial to improving the reliability of connection.

In one embodiment, in order to avoid the elastic member 400 contacting the machined part during rotation, thereby affecting the quality of the machined part, the whetstone base plate 220 may be provided with a first groove 221, the opening of the first groove 221 is oriented in the same direction as the axial direction of the main shaft of the honing machine, and the elastic member 400 is disposed in the first groove 221. Since the elastic member 400 is disposed in the first groove 221, the elastic member 400 can be prevented from contacting with the processed component during rotation, thereby facilitating the improvement of the quality of the processed component.

In a further alternative embodiment, in order to achieve a quick installation of the whetstone base plate 220, one of the whetstone base plate 210 and the whetstone base plate 220 is provided with a protrusion, and the other is provided with a recess, the protrusion being in a positioning fit with the recess. And the processing technology of the grooves and the protrusions is complex.
