[0020] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0021] See also Figure 1-4 The utility model provides a high-precision hole processing honing tool, which includes a connecting plate 3, a base 4, a honing seat 2, and a honing strip 1.

[0022] The connecting plate 3 is used to connect the tool holder of the machine tool, and a conventional structure that can be connected can be used. The base 4 is fixedly connected to the connecting plate 3 by bolts. An adjusting through hole and a limiting groove are set on the base 4. The honing seat 2 is set in the limiting groove, and the thickness of the honing seat 2 is consistent with the width of the limiting groove. The axial direction of the adjusting through hole is perpendicular to the central axial direction of the connecting plate 3. An adjusting rod 5, a spring 6 and a positioning column 7 are set in the adjusting through hole. The positioning column 7 is threadedly connected to the honing seat 2. The two ends of the spring 6 are respectively against the positioning column 7 and the adjusting rod 5. The adjusting rod 5 is threadedly connected to the adjusting through hole. It can be seen from this that the honing seat 2 can only move along the axial direction of the adjusting through hole, and the limiting groove has the function of limiting the rotation of the honing seat 2. The position of the adjusting rod 5 in the adjusting through hole can be changed by screwing the adjusting rod 5.

[0023] A slot 21 is provided on the surface of the honing seat 2 facing away from the base 4, and the honing bar 1 is provided in the slot 21 and is connected to the honing seat 2 by adhesive bonding. The honing bar 1 is used to hone the inner wall of the hole on the workpiece. An anti-slip keyway 22 is provided on the side of the honing seat 2, and a pin extending into the anti-slip keyway 22 is provided on the base 4. The cooperation between the pin and the anti-slip keyway 22 limits the moving distance of the honing seat 2, and also limits the maximum and minimum diameters of the holes that can be processed by the tool.

[0024] When in use, the connecting plate 3 is connected to the tool holder of the machine tool, and then the position of the adjusting rod 5 is adjusted based on the size of the hole to be honed and the amount of honing. First, the position of the adjusting rod 5 is adjusted so that the spring 6 can contact the inner wall of the hole in a natural state. When the honing stick 1 is against the inner wall of the hole, if the position of the adjusting rod 5 is adjusted in this state so that the spring 6 is compressed, the honing force can be applied with the help of the spring 6. The tighter the spring 6 is compressed, the greater the honing force.

[0025] In summary, this tool can be installed on the machine tool holder of the horizontal machining center, and the flexible machine tool holder of the horizontal machining center can be used to carry out honing processing, so there is no need for transfer process. It can also be used for workpieces of various sizes or shapes, with greater flexibility and suitable for different honing production needs.
