Technical Field

[0001] The utility model belongs to the technical field of milling machine milling machinery, in particular to a dial indicator mounting seat used for clamping a tool handle of a milling machine. Background Art

[0002] When using a milling machine to mill workpieces, due to the large differences in some individual workpieces, the results of processing according to a specific processing program in accordance with a fixed workpiece coordinate system are theoretically offset, resulting in workpiece out-of-tolerance. In this case, the workpiece needs to be measured separately before processing, and then the measurement results are fed back to the coordinate system offset or CNC program for corresponding compensation. The commonly used measurement method is dial measurement. The general steps are to install the dial on the dial frame, and adsorb it on the end face or side of the machine tool spindle through the magnetic base. The workpiece reference surface and the surface to be processed are measured in turn to obtain the difference, and then the corresponding compensation is made. The operation is cumbersome and inefficient. Utility Model Content

[0024] Example

[0025] like Figure 1-4 As shown, Figure 1 As shown, a dial indicator mounting seat for clamping a milling machine tool handle includes a seat body 1, a tightening nut 2, and a tightening screw 3.

[0026] The upper part of the seat body 1 is a cylindrical structure clamping part 11, and the middle part is a circular ring structure 12. The bottom of the ring protrudes inward along the circumference, and a certain number of narrow groove openings are evenly distributed along the radial direction of the protruding part. There is an ear piece 121 on the top of the ring, and there is a threaded hole on the ear piece 121 along the radial direction of the ring. There is a milled long through groove along the axial center position of the upper cylinder, and the groove runs all the way to the center of the middle circular ring structure 12. The lower part is a cylindrical tube 13, and the cylindrical surface is a threaded feature. The inner hole diameter of the middle circular ring structure 12 is slightly larger than the diameter of the dial indicator bezel, so as to ensure that the dial indicator 4 can be placed in the seat body 1. At the same time, in order to avoid installation interference, the upper cylindrical clamping part 11, the middle circular ring structure 12, and the lower cylindrical tube 13 are grooved at the interference positions with the dial indicator shaft sleeve, side head and other components;

[0027] The locking nut 2 is a rotating shaft part, with a threaded hole on the upper part, the hole diameter of which corresponds to the external thread on the lower part of the seat body 1, and a tapered hole on the lower part, the taper of which is consistent with the taper of the dial indicator sleeve. In the process of tightening the locking nut 2, the tapered hole part of the locking nut 2 will gradually approach the tapered part of the dial indicator sleeve, and finally fit tightly;

[0028] One end of the fastening screw 3 is characterized by an external thread, the thread corresponding to the threaded hole on the ear piece 121 of the seat body 1, and the other end can be a cylinder or other structure;

[0029] The utility model can install a universal dial indicator 4 thereon, and the upper cylindrical part of the seat body 1 can be installed on the ER retaining ring or the strong tool handle 5. After the installation is completed, the clamping force of the tool handle 5 shrinks the opening of the through slot on the cylindrical clamping part 11, and finally presses the dial indicator dial. At the same time, the locking nut 2 will further strengthen the installation of the dial indicator 4. After the dial indicator pointer is aligned with zero, the position of the dial ring is fixed by tightening the screw 3. The dial indicator can be quickly installed on the machine tool spindle together with the mounting seat or returned to the machine tool magazine as a whole through the tool change command of the machine tool.

[0030] The above is only a specific embodiment of the utility model, and the utility model is described in detail. The undetailed part is conventional technology. However, the protection scope of the utility model is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. The protection scope of the utility model shall be based on the protection scope of the claims.
