[0027] Example

[0028] Reference Figure 1-2 As shown, the utility model discloses a seismic-resistant inner hole fixed tool holder, including a tool holder body 10. The tool holder body 10 includes a tool bar clamping module and a fixing module from top to bottom. The tool bar clamping module is used to install the tool bar, and the fixing module is used to fix the tool holder body 10.

[0029] Reference Figure 1-4 As shown, the tool rod clamping module includes a accommodating hole 101, the diameter of the accommodating hole 101 is larger than the tool rod, and the tool rod can be quickly installed and inserted. A horizontal gap 102 is opened on the side close to the accommodating hole 101, and a plurality of vertical downward tightening threaded holes 103 are opened on the side of the tool holder body 10 close to the horizontal gap 102. The tightening threaded holes 103 pass through the horizontal gap 102. In this embodiment, the tightening threaded holes 103 include 4. When the tool rod is installed, the tool rod is inserted into the accommodating hole 101, and the bolts are locked from the tightening threaded holes 103 to reduce the horizontal gap 102, so that the accommodating hole 101 is completely fitted and fixed with the tool rod, so that the tool rod is fixed in the accommodating hole 101. Compared with the traditional method of tightening the tool rod in the accommodating hole 101 by bolts, this method has good wrapping, strong rigidity, is not easy to vibrate, and improves the processing accuracy of the workpiece. Furthermore, assuming that the height of the horizontal gap 102 is X, 2.0 mm ≥ X ≥ 1.8 mm, the horizontal gap 102 can be set according to tools of different diameters to better adapt to tool rods of different diameters. In this embodiment, the horizontal gap 102 is 1.9 mm.

[0030] Reference Figure 1-4As shown, a top threaded hole 104 is opened between the clamping threaded holes 103 on the tool holder body 10, and the lower end of the top threaded hole 104 is connected to the horizontal gap 102, and the top threaded hole 104 is arranged between the clamping threaded holes 103. Specifically, when the tool bar needs to be pulled out from the receiving hole 101, the bolt in the clamping threaded hole 103 is first loosened, and then the bolt in the top threaded hole 104 is tightened so that the lower end of the bolt is against the lower end surface of the horizontal gap 102, which plays a role in opening the horizontal gap 102, making it convenient to take the tool bar out of the receiving hole 101 and disassembly. Further, the fixing module further includes a T-shaped mounting groove 107 opened at the bottom of the tool holder body 10, and the T-shaped mounting groove 107 cooperates with the T-shaped positioning block on the machine tool to play a positioning role in fixing the fixed tool holder, and the T-shaped mounting groove 107 has a plurality of positioning holes 1071, and the positioning holes 1071 further play a role in positioning and fixing the tool holder body 10, thereby improving the positioning accuracy.

[0031] Reference Figure 1-4 As shown, the fixing module includes a plurality of mounting holes 108 opened at the bottom of the tool holder body 10. Bolts pass through the mounting holes 108 to fix the tool holder body 10 on the machine tool. In this embodiment, there are four mounting holes 108, which are respectively arranged on both sides to further improve the installation stability of the tool holder body 10.

[0032] Reference Figure 1-4 As shown, a nozzle installation groove 105 is provided at one end of the tool holder body 10 along the length direction, and the nozzle installation groove 105 is placed below the accommodating hole 101. When processing a workpiece, a nozzle (not shown in the figure) is installed in the nozzle installation groove 105, and the nozzle sprays coolant at the workpiece to cool the workpiece and improve the processing accuracy of the workpiece. The side and bottom of the tool holder body 10 are respectively provided with connecting holes 106 connected to the nozzle installation groove 105. The coolant enters the nozzle installed in the nozzle installation groove 105 from the connecting hole 106 and sprays out, and the coolant is transmitted from the tool holder body 10, avoiding external pipes, and the structure is simple and easy to operate.

[0033] Reference Figure 5 As shown, in another embodiment, an end cap 20 is provided at one end of the tool holder body 10 along the length direction of the receiving hole 101, and a through hole connected to the bottom is opened at the end of the tool holder body 10 where the end cap 20 is provided, and a water outlet groove 201 and a connecting groove 202 are opened at the end of the end cap 20 facing the receiving hole 101, and the water outlet groove 201 is connected to the connecting groove 202. Specifically, when the end cap 20 is installed on the tool holder body, the connecting groove 202 is aligned with the through hole, and the water inlet hole at the rear end of the tool rod is aligned with the water outlet groove 201 at the center position. External cooling also enters from the through hole at the bottom through the connecting groove 202 to the water outlet groove 201 and finally sprays out through the front end of the tool rod, which can withstand a water pressure of 150Mpa. The traditional fixed tool holder structure needs to connect a water pipe to the tool rod, which will cause interference or entanglement. The utility model transports coolant from the inside of the tool holder, and the structure is simpler.

[0034] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
