The plurality of oilstone mounting blocks 13 are evenly arranged along the circumference of the honing rod 1, and an oilstone for honing processing is fixedly mounted on the oilstone mounting block 13. The oilstone mounting block 13 is slidably connected to the honing rod 1, and the sliding direction is the radial direction of the honing rod 1. The honing rod 1 is provided with an adjustment mechanism 2 for controlling the synchronous movement of each oilstone mounting block 13. The adjustment mechanism 2 changes the radial size that the honing head can process by controlling the distance between the oilstone mounting block 13 and the axis of the honing rod 1. A mounting flange 12 is fixedly connected to the end of the honing rod 1 away from the oilstone mounting block 13, and a plurality of mounting bolts 121 are penetrated on the mounting flange 12. The honing rod 1 can be installed on the spindle of various machine tools through the mounting flange 12 and the mounting bolts 121 as needed.

[0030] like Figure 1-3 As shown, an adjustment cavity is provided inside the honing rod 1 along its length direction, and the adjustment mechanism 2 includes an adjustment rod 21, an adjustment member and a metal spring ring 25. The adjustment rod 21 is located in the adjustment cavity and is slidably connected to the honing rod 1, and the sliding direction is the axial direction of the honing rod 1; two adjustment cones 22 are coaxially fixedly connected to the adjustment rod 21, and the two adjustment cones 22 are arranged in sequence along the axial direction of the adjustment rod 21. Each oilstone mounting block 13 is integrally formed with two thrust wedge surfaces 131 on one side located in the adjustment cavity, and a single thrust wedge surface 131 abuts against the conical surface of an adjustment cone 22. When the adjustment rod 21 moves, a thrust perpendicular to the axis of the adjustment rod 21 is applied to the thrust wedge surface 131 through the adjustment cone 22, so that the oilstone mounting block 13 moves in a direction away from the axis of the adjustment rod 21. The metal spring ring 25 is sleeved on the outside of the honing rod 1, and a circle of oilstone mounting blocks 13 are surrounded by the metal spring ring 25 and abut against their inner edges, so that the metal spring ring 25 and the adjusting cone 22 clamp and abut against each oilstone mounting block 13, so that the oilstone mounting block 13 can remain stable in the adjusted position.

The operation slot 11 is connected to the adjustment cavity. The length direction of the operation slot 11 is the circumference of the honing rod 1. When the screw core 23 rotates, different adjustment slots 231 are selectively connected to the operation slot 11. The length of the operation slot 11 is equal to the spacing between two adjacent adjustment slots 231. The operator can use a rod-shaped object to pass through the operation slot 11 and insert it into the adjustment slot 231, so as to apply a rotational thrust to the screw core 23. The maximum single stroke of the operator using the rod-shaped object for rotation operation is the length of the operation slot 11, that is, the maximum angle that the screw core 23 can rotate in a single operation is 60°.

The port of the oil delivery channel 212 is located at the end of the adjusting cone 22 relatively far away from one end of the screw core 23; the adjusting rod 21 is also provided with an oil hole 214 and an oil delivery groove 213, the length direction of the oil hole 214 is the radial direction of the adjusting rod 21, the oil delivery groove 213 is located on the outer wall of the adjusting rod 21 and the length direction is consistent with the length direction of the adjusting rod 21, one end of the oil hole 214 is connected to the oil delivery channel 212, and the other end is connected to the oil delivery groove 213, and the port of the oil delivery groove 213 is located on the conical surface of the adjusting cone 22 closer to the screw core 23. Lubricating oil is injected into the adjustment cavity, and the lubricating oil can move to between the adjustment cone 22 and the thrust wedge surface 131 through the oil delivery channel 212 and the oil delivery groove 213 to lubricate the contact position between the two, thereby improving the smoothness during adjustment and the movement accuracy of the oilstone mounting block 13.

When the execution block 31 and the adjustment slot 231 are aligned, the execution block 31 can be moved into the adjustment slot 231. In order to improve the smoothness of the execution block 31 entering the adjustment slot, a mating arc surface 311 is provided on the end of the execution block 31 facing the screw core 23. The relay block 3 is provided with a control component 32 for controlling the movement of the execution block 31. The control component 32 includes a control knob 321 and a control tension spring 323.

Compared with the first embodiment, in the operation process of the scheme of this embodiment, after the operator inserts the rod-shaped tool with a hexagonal structure into the non-circular hole 3211, the torque transmission path for the screw core 23 is built by rotating it at a certain angle, and there is no need to pull the rod-shaped tool out of the non-circular hole 3211, thereby improving the convenience of operation during the continuous rotation of the screw core 23.
