The precision-positioning, quick-change, self-testing honing head of this application achieves rapid replacement and precise positioning of the honing head 1 by setting a connector 3 between the honing head 1 and the connecting rod 2, and by setting an internal air passage 31 at the end face of the connector 3 and an internal air passage 21 at the end face of the connecting rod 2. This design ensures the air supply path required for pneumatic measurement. When replacing the honing head 1, there is no need to remove the external air pipe; simply loosen the locking nut 7 and the locking sleeve 6 to easily remove the assembly of the honing head 1 and the connector 3, then replace it with a new assembly of the honing head 1 and the connector 3, and finally adjust the angle and lock it using the spherical universal pad 5 to complete the replacement, greatly improving work efficiency.

[0033] Further, please refer to Fig. 1 and Fig. 3The internal ventilation pipeline 11 arranged in the end face of the honing head 1 is connected with the internal ventilation pipeline 31 of the adapter through the hose 4. This design not only ensures smooth transmission of the air source, but also enables the honing head 1 to maintain the integrity of the ventilation pipeline during replacement without disconnecting the air path, further improving the convenience and efficiency of replacement. At the same time, the flexible connection of the hose 4 also enhances the adaptability and stability of the entire air source passage.

[0034] Further, please refer to Fig. 2 The adapter 3 and the honing head 1 are axially fixed through the spherical universal pad 5, the locking sleeve 6 and the locking nut 7. This design not only realizes accurate positioning of the honing head 1 and the connecting rod 2, but also allows the honing head 1 to be adjusted in a certain range to adapt to different processing requirements. The design of the spherical universal pad 5 enables the honing head 1 to be automatically aligned during installation, improving the accuracy and convenience of installation.

[0035] Further, the adapter 3 is provided with symmetrical adapter grooves 32 at the top, which are matched with the internal keys 22 of the connecting rod 2. This design realizes quick positioning and connection between the adapter 3 and the connecting rod 2, and at the same time transmits the rotary torque, ensuring the stability and accuracy during honing.

[0036] Further, in order to facilitate accurate positioning and connection of the adapter 3 and the connecting rod 2, the end of the adapter 3 is designed as a taper, which is matched with the internal taper hole arranged at the end of the connecting rod 2.

[0037] In the prior art, the end of the honing head 1 is cylindrical, and the connecting rod 2 is provided with an internal cylinder matched with the end of the honing head 1. During connection, the end of the honing head 1 is inserted into the internal hole of the connecting rod 2, and then the hanging pin 8 is connected, so as to realize connection of the connecting rod 2 and the honing head 1.

[0038] In the present embodiment, the adapter 3 connecting the connecting rod 2 and the honing head 1 is designed as a taper at the end matched with the connecting rod 2.
