专利汇可以提供Expandible honing heads专利检索，专利查询，专利分析的服务。并且A honing head is constructed with at least two honing members so that two co-axial bores, not necessarily of the same diameter can be honed simultaneously. A mechanism serves to expand the honing members simultaneously and in dependence upon the resistive torque detected by a detector. A pneumatic device including a nozzle connected in a circuit serves to detect when one of the honing members contacts the corresponding bore to be honed. This contact serves to increase by a predetermined value, depending on the particular honing member at which contact was detected, the value of the resistive torque.，下面是Expandible honing heads专利的具体信息内容。

权利要求

1. In a honing head at least two expandible honing members, mechanism for expanding the honing members simultaneously, a resistive torque detector, control means operative to actuate the said mechanism in dependence upon the resistive torque detected by the detector, a pneumatic device incorporated in one of the honing members and arranged to detect contacT of the honing member with the corresponding bore, and means responsive to contact of the honing member whereby the resistive torque can be increased by a predetermined value depending on the particular honing member at which contact was detected.

2. A honing head according to claim 1, in which the pneumatic device comprises a nozzle connected to the corresponding honing member, a compressed air supply means, and a flow regulator connecting the air supply means and the nozzle.

3. A honing head according to claim 1, comprising a control circuit of the expanding mechanism, and a pilot valve in the control circuit, including a valve body, and a slide, movement of said valve body being controlled by the resistive torque detector and movement of the slide being controlled by the contact responsive means.

4. A honing head according to claim 3, comprising a first capsule, and a second capsule, said valve body and said slide being secured to one diaphragm of a respective said capsule.

5. A honing head according to claim 4, in which the interior of said first capsule is in communication with the torque detector.

6. A honing head according to claim 4, in which the interior of the second capsule is in communication with the contact responsive means.

7. A honing head according to claim 4, comprising a pressure contact, an electrically-operated valve controlled by the pressure contact, a compressed air supply means, and a circuit connecting the compressed air supply means and one of said capsules, said contact detecting means being in communication with said pressure contact and said pressure contact by-passing said circuit connecting the air supply means and one of the capsules.
