[0001] The utility model relates to the technical field of thread milling cutters, in particular to a multifunctional thread milling cutter. Background Art

[0002] The development of CNC machining technology, particularly the emergence of three-axis CNC machining systems, has made CNC thread milling, a more advanced thread processing method, possible. Compared to traditional thread machining methods, thread milling offers significant advantages in precision and efficiency. Furthermore, thread milling is not restricted by thread structure or thread rotation. For example, a single thread milling cutter can produce a variety of internal and external threads with varying rotation directions.

[0003] Currently, most CNC tools on the market are single-function and simple in design. Large CNC machine tools and machining centers often have toolholders or tool magazines inside, which, to a certain extent, limits the reduction of processing time and the improvement of processing efficiency. During operation, the milling cutter generates a large amount of heat and debris, which can cause severe wear of the milling cutter, thus affecting the machining accuracy of the workpiece and making it inconvenient to replace the cutter head, which indirectly increases processing costs. Therefore, we propose a multifunctional thread milling cutter. Utility Model Content

[0033] It should be noted that the mounting assembly 4 includes a mounting tube 6, which has a hollow structure inside and is made of stainless steel. A clamping block 7 is fixed inside the mounting tube 6, and the clamping block 7 is tapered as a whole. A limiting ring 8 is provided on the outside of the clamping block 7 for sliding. The more the limiting ring 8 moves downward, the tighter the clamping block 7 clamps.

[0034] In addition, a slide groove 11 is provided on the outside of the mounting tube 6, and a slide plate 9 is fixedly connected to the outside of the limiting ring 8 through the slide groove 11. By moving the slide plate 9, the limiting ring 8 can be driven to move up and down, so that the knife rod 1 can be installed and replaced. The outside of the slide plate 9 is fixedly connected to the limiting rod 10, and the limiting rod 10 is L-shaped. The outside of the mounting tube 6 is fixedly connected to the fixing block 12, and a limiting hole 13 is provided inside the fixing block 12. The shape of the limiting hole 13 corresponds to the limiting rod 10. By inserting the limiting rod 10 into the inside of the limiting hole 13, it is convenient to limit the mounting component 4, thereby enhancing the connection effect of the mounting component 4.

[0035] Further, such as Figure 3 As shown, a magnetic plate 15 is fixedly connected just above the slide groove 11, and a protrusion 14 is fixedly connected to the top of the slide plate 9. The protrusion 14 is an iron sheet, and the protrusion 14 corresponds to the magnetic plate 15.

The knife rod 1 only needs to be inserted into the mounting tube 6, which is convenient for users to replace the knife rod 1 and thus convenient for users to use.

[0037] Example 2:

[0038] On the basis of Example 1, according to Figure 2 、 Figure 5 and Figure 6 As shown, it is worth noting that the combined mechanism 5 includes a cylinder 17, the interior of the cylinder 17 is a hollow structure, which provides an installation space for the internal structure of the combined mechanism 5, and the cylinder 17 is fixedly mounted on the top of the mounting cylinder 6. A suction pump 18 is fixedly mounted inside the cylinder 17. The specific model of the suction pump 18 is selected according to actual conditions. The output end of the suction pump 18 is fixedly connected to an input pipe 19, and the output end of the suction pump 18 is fixedly connected to an output pipe 20. Both the input pipe 19 and the output pipe 20 are made of stainless steel.

[0039] The middle part of the input pipe 19 is fixedly connected to a cooling box 21, which is used to hold coolant. A through pipe is provided on the outside to facilitate the addition of coolant. The end of the input pipe 19 away from the suction pump 18 is fixedly connected to a dust collection box 22. A filter is provided inside the dust collection box 22. The filter can filter debris inside the dust collection box 22 and then discharge it through the discharge pipe. The outside of the dust collection box 22 is fixedly connected to a dust collection pipe 24. The outside of the output pipe 20 is fixedly connected to an air outlet pipe 29. The end of the output pipe 20 away from the suction pump 18 is fixedly connected to a drain pipe 23. The input pipe 19, the dust collection pipe 24, A control valve 25 is fixedly provided on the outside of the drain pipe 23 and the air outlet pipe 29. When heat dissipation is required, the suction pump 18 is started, and the suction pump 18 absorbs the coolant inside the cooling box 21 and discharges it into the cooling hole 26 through the output pipe 20 and the drain pipe 23, so as to facilitate cooling the tool rod 1, thereby increasing the service life of the tool rod 1. At the same time, the dust suction pipe 24 can be controlled by starting the control valve 25, and then the debris is sucked into the dust box 22 through the dust suction hole 27, and the filtered air is discharged through the air outlet pipe 29. An air vent is opened on the outside of the cylinder 17 to facilitate gas discharge.

[0040] It should be noted that the inside of the tool rod 1 is symmetrically provided with through grooves 28, and the drain pipe 23 and the dust suction pipe 24 are both stuck in the inside of the through grooves 28. The outside of the tool rod 1 is symmetrically fixed with cooling holes 26, and the other side of the cooling holes 26 is provided with dust suction holes 27.

[0041] In this solution, the working principle used is as follows:

[0042] First, when the shank 1 needs to be replaced, the slide plate 9 is pushed upward to disengage the limiting rod 10 from the limiting hole 13. The protrusion 14 is attracted to the magnetic plate 15, which in turn drives the limiting ring 8 to slide upward, so that the clamping block 7 is expanded, and the shank 1 can be removed from the interior of the mounting cylinder 6.

[0043] Next, replace the new cutter bar 1, align the indicator 16 with the position of the slide groove 11, and then insert the drain pipe 23 and the dust suction pipe 24 into the through groove 28 inside the cutter bar 1 respectively;

[0044] Next, the suction pump 18 is started to absorb the coolant in the cooling box 21 and discharge it into the cooling hole 26 through the output pipe 20 and the drain pipe 23, so as to cool the tool bar 1;

[0045] Finally, when the threaded tooth plate 2 is working on the workpiece, the valve outside the dust suction pipe 24 is started to absorb the debris into the dust suction box 22 through the dust suction hole 27, and the filtered air is discharged through the air outlet pipe 29.

[0046] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are intended only as examples and do not limit the present invention.
