た。2. Description of the Related Art A cylindrical structure as described above is formed into a predetermined diameter and shape, and then the inner surface is processed by a honing machine. A honing machine that performs this processing has a plurality of grindstone holders holding a grindstone attached to a rotating head, and inserts the rotating head into a cylindrical structure that is a workpiece and rotates the grindstone holder. It is also used to rotate the grindstone to polish the inner surface. In this polishing, it is necessary to prevent abrasion of the grindstone and a loss of contact with the inner surface of the workpiece. For this reason, conventionally, a spring (or a single spring) is provided at each mounting portion or the whole of the grindstone holder in the rotary head, and the spring urges the grindstone holder in the advance direction.
It had a structure to ensure the corrosion of the grindstone with the inner surface of the workpiece.

た。However, in the conventional honing machine, a spring is arranged for each of the grindstone holders, and each spring or a single spring urges the grindstone holder. It is necessary to attach the grindstone holder so that the two are engaged. For this reason,
Attachment and removal of the whetstone at the time of replacement is troublesome. Also,
When the urging force of the spring causes the grinding wheel to set, the urging force is weakened, so that all of the grindstone holders cannot be urged with a uniform spring force all the time, resulting in variation in the polishing force. Moreover, when only the grindstone of a specific grindstone holder wears, the grindstone must be replaced each time the wear occurs, and the replacement frequency increases and workability also deteriorates. Further, when the wear of the grindstone progresses beyond a certain level, the urging force of the spring cannot follow this, and the contact force of the grindstone with the workpiece is weakened, so that there is a problem that the polishing force is rapidly reduced.

It is possible to easily replace a grindstone holder, to urge all the grindstone holders with an equal force, and to further reduce the amount of wear of the grindstone. It is an object of the present invention to provide a honing machine capable of maintaining a contact force with a workpiece independently of the honing machine.

Therefore, regardless of the wear amount of the grindstone, the grindstone can be brought into contact with the inner surface of the workpiece, and the polishing can be performed smoothly. Also, each grinding wheel holder should be attached to the rotating head so that it comes into contact with the cam member, and the attachment and detachment structure becomes simple,
The replacement can be performed easily and quickly.

As a result, the cam member 17 simultaneously pushes out all the grindstone holders 9, so that the grindstone holder 9 advances, and the grindstone 8 contacts the inner surface of the workpiece 5. Then, by driving the rotation drive source 1, the air cylinder 7 is rotated, and the grindstone holder 4 connected to the air cylinder 7 is rotated. Thereby, the grindstone 8 polishes the inner surface of the workpiece 5. When the grindstone 8 is worn during the polishing and the contact with the inner surface of the workpiece 5 becomes insufficient,
By supplying air to the air cylinder 7 and moving the shaft 15 downward, the pushing force by the cam member 17 is increased. As a result, the grindstone holder 9 advances,
The grindstone 8 is in good contact with the workpiece 5. In such a configuration, even if the grindstone 8 is worn, the grindstone holder 9 can be advanced in accordance with the amount of wear, so that the contact state with the workpiece 5 can be maintained in a favorable state, and the polishing can be reliably performed. ,
Moreover, it can be performed continuously and quickly. Further, since the cam member 17 simultaneously advances all the grindstone holders 9 by the same amount, all the grindstone holders 9 are biased by an equal force. Thereby, all the grindstones 8 come into contact with the workpiece 5 with a uniform contact force, so that polishing with a uniform polishing force becomes possible.

行うことができる。The above-described polishing is performed in the order of rough polishing and finish polishing, and it is necessary to replace the grindstone 8 with a grain size corresponding to each polishing step. In this case, the grindstone holder 9 having the grindstone 8 is attached to the rotary head 4, but this attachment only needs to insert the shaft portion 9b into the mounting cylinder 20, and the exchange of the grindstone holder 9 is extremely easy. Moreover, it can be performed quickly.

換も容易となる。According to the present invention, a cam member is attached to a shaft which moves in the axial direction, and all the grindstone holders are simultaneously advanced by the cam member, so that a uniform urging can be performed and all the grindstones can be uniformly processed. Can be contacted. Therefore, it is possible to perform polishing without variation. Also, even if the grindstone is worn by polishing, it can be brought into good contact between the grindstone and the workpiece only by operating the operating member and moving the shaft in the axial direction, thereby enabling continuous polishing. Thus, rapid processing becomes possible. Further, according to the present invention, since the shaft portion of the grindstone holder is inserted into the mounting cylinder of the rotary head, the grindstone holder can be easily mounted and easily replaced.
