[0019] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0020] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] like Figure 1-Figure 5As shown, a tool axial radial adjustment mechanism comprises a main handle 1, an adjustment ring 2, a connecting handle 3, a tool bar 4, a threaded hole 1 5, a hexagon socket bolt 6, and a threaded hole 2 7, wherein: an adjustment ring 2 is sleeved on the outer circle of the connecting surface between the main handle 1 and the connecting handle 3, a groove for bearing the extrusion of the screw is arranged on the adjustment ring 2, a circular conical surface adapted to the conical surface at the bottom end of the connecting handle 3 is cut at the bottom end of the tool bar 4, the tool bar 4 is inserted into the connecting handle 3 from the front end of the connecting handle 3, a washer is arranged on the parallel end surfaces of the tool bar 4 and the bottom end of the connecting handle 3, the hexagon socket bolt 6 passes through the washer and is tightened in the threaded hole 2 7 at the center of the bottom end of the tool bar 4, so that the tool bar 4 and the connecting handle 3 are tightly connected. The connecting surfaces of the main handle 1 and the connecting handle 3 are provided with threaded holes corresponding to each other, and are connected by bolts. The center of the connecting handle 3 is provided with an inner hole that passes through the center line of the connecting handle 3, and the bottom end of the inner hole is provided with a circular cone surface, and the cone hole of the circular cone surface can extend to an angle of 7 0 Up to 10 0 The inner diameters of the remaining holes other than the tapered hole on the circular conical surface of the connecting handle 3 are 4 to 6 threads larger than the diameters of the remaining holes other than the tapered hole on the circular conical surface of the knife bar 4. The outer circle of the front end of the connecting handle 3 is surrounded by four mutually corresponding threaded holes 1 5 in the front, back, left, and right directions, and the threaded holes 1 5 penetrate the outer wall of the connecting handle 3. The center of the bottom end face of the knife bar 4 is provided with a threaded hole 2 7.

[0022] First, insert the tool rod 4 into the connecting handle 3 from the front end of the connecting handle 3. Since the bottom end of the tool rod 4 is provided with a circular conical surface that adapts to the bottom end of the connecting handle 3, the conical surfaces of the two will be slightly squeezed and deformed and fit together during the insertion of the tool rod 4. A washer is placed on the parallel end surfaces of the bottom ends of the tool rod 4 and the bottom ends of the connecting handle 3. The hexagon socket bolt 6 passes through the washer and is tightened in the threaded hole 7 at the center of the bottom end of the tool rod 4 to achieve a tight combination of the tool rod 4 and the connecting handle 3. Then, use screws to install the connecting handle 3 on the main handle 1 through the corresponding threaded holes on the connecting handle 3 and the main handle 1. Then, install the main handle 1 on the main shaft of the machine tool. Finally, the adjusting ring 2 is sleeved on the outer circle of the connecting surface between the main handle 1 and the connecting handle 3.

[0023] Perform axial adjustment first, then radial adjustment. Figure 5As shown, axial adjustment is to adjust the tool rod 4 to be perpendicular to the actual working surface. The four screws corresponding to the four threaded holes 5 arranged around the outer circle of the connecting handle 3 are used to adjust the verticality of the tool rod 4 and the actual working surface. During the adjustment process, the screws in the opposite direction of the tool rod 4 need to be moved. Since the inner hole diameter of the connecting handle 3 is larger than the diameter of the tool rod 4, the four screws are first passed through the threaded holes 5 on the connecting handle 3 to reach a pre-tightened state, and then the corresponding screws are tightened according to the moving direction of the tool rod 4 that needs to be adjusted. While tightening, the screws will push against the tool rod 4, causing the tool rod 4 to move. When the tool rod 4 is completely perpendicular to the actual working surface, all the four screws are tightened.

[0024] like Figure 1-Figure 3 As shown, radial adjustment is to adjust the center points of the two radial surfaces of the main handle 1 and the connecting handle 3 to be consistent. When the adjustment ring 2 is put on the outer circles of the two connecting surfaces of the main handle 1 and the connecting handle 3, a radial runout detection is performed using a traditional tool runout method. The direction that requires radial adjustment is found through detection, and then a screw is used to squeeze the groove on the adjustment ring 2 to achieve radial adjustment, so that the radial center points of the main handle 1 and the connecting handle 3 are finally consistent.

[0025] The above description is only an explanation of the preferred embodiments of the present application and the technical principles and other schemes used. At the same time, the scope of the invention involved in the present application is not limited to the technical scheme formed by a specific combination of the above technical features, but also includes other technical schemes formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) to form a technical scheme.
