Definitions
- the present invention relates to a grinding wheel head for a honing head. More specifically, the present invention relates to a grinding wheel head for a honing head for honing the inner diameter of a hole having a non-circular cross section formed in a workpiece.
- the bore of the engine cylinder block is cut, and then the cylinder head and crankcase are assembled to the cylinder block. Since the piston accommodated in the bore has a perfect circular cross section, it is cut so that the cross sectional shape of the bore is close to a perfect circle.
- the shape of the bore is deformed when a cylinder head, a crankcase, or the like is assembled. If the bore is deformed in this way, it becomes a factor that increases the sliding resistance between the bore and the piston when the engine is used, and the engine may not exhibit the desired performance.
- the dummy head is mounted on the cylinder block, and the bore is machined into a perfect circular shape by a machine tool.
- NC data is generated by measuring the entire shape of the bore after removing the dummy head.
- bore shape data is obtained by simulation. Thereafter, based on the generated NC data or the acquired shape data, the cylinder block is bored without mounting the dummy head. In this way, even if the bore is processed without attaching the dummy head to the cylinder block, the bore becomes a perfect circle when the cylinder head is mounted.
- the honing head described in Patent Document 1 has the following problems. That is, since the elastic body is provided between the main shoe and the auxiliary shoe of the grindstone shoe from the upper end to the lower end of the grindstone shoe without any break, the auxiliary shoe cannot swing with respect to the main shoe. That is, for example, only the upper end side of the auxiliary shoe approaches or separates from the main body shoe, only the lower end side approaches or separates, and the lower end side cannot separate or approach while the upper end side approaches or separates.
- the inner surface shape of the bore of the cylinder block obtained by performing boring processing based on such NC data also includes a portion deviated from parallel to the axial direction.
- the auxiliary shoe of the grindstone shoe can follow the shape of the inner surface of the bore that is deviated from being parallel to the axial direction. This part is scraped off. That is, the non-circular cross-sectional shape of the bore obtained by the boring process is scraped off in a direction closer to the circular cross-section.
- the grindstone of the honing head in addition to maintaining the surface pressure of the grindstone to be substantially constant, the grindstone of the honing head that can follow the shape of the inner surface of the portion deviated from parallel to the axial direction. Provide a stand.
- the grinding wheel head of the honing head is externally arranged with respect to the holder (for example, the holder 11 described later) of the honing head (for example, the honing head 10 described later).
- the grindstone portion is swingably attached to the support portion via one or a plurality of spring members (for example, a coil spring 16 to be described later) disposed at an interval in the axial direction of the holder.
- the grindstone portion in addition to being able to keep the surface pressure of the grindstone almost constant by the spring member, the grindstone portion can be swung relative to the support portion with the spring member as a fulcrum. Therefore, the grindstone can smoothly follow the shape of the inner surface of the part shifted from parallel to the axial direction of the hole of the workpiece, and the honing process (rough machining and surface Finishing).
- the grinding wheel head of the honing head is arranged on the outside with respect to a holder (for example, a later-described holder 41) of the honing head (for example, a later-described honing head 40).
- a honing head grindstone table on which a plurality of grindstone tables (for example, a grindstone table 42 described later) equipped with grindstones 45, 45a, 45b (described later) can be expanded in a radial direction
- a support portion for example, a support portion 43 described later
- a grindstone portion for example, a grindstone portion 44 described later
- the grindstone portion is divided into a plurality of grindstone members (for example, grindstone members 44a and 44b described later) along the axial direction of the holder.
- Each of the grindstone members is swingably attached to the support portion via one or a plurality of spring members (for example, coil springs 46a and 46b described later) arranged at intervals in the axial direction of the holder. It is done.
- This structure has the same effect as described above. Furthermore, since the grindstone portion is divided into a plurality of grindstone members along the axial direction, even when the hole of the workpiece has a complicated inner surface shape along the axial direction, the grindstone can be copied smoothly. be able to.
