Description

Technical Field

[0001] This utility model relates to the field of tool holder technology, specifically to a tool holder mechanism with stable mechanical properties. Background Technology

[0002] CNC machine tools are short for numerical control machine tools. They are automated machine tools equipped with a program control system. The tool holder is the carrier that connects the cutting tool and the machine tool in a CNC machine tool.

[0003] Currently, commonly used tool holders typically mount the cutting tool directly on them and connect the tool holder with the tool to the machine tool. When the machine tool drives the cutting tool to process the workpiece, the chips generated by the cutting tool will splash and hit the connection between the tool holder and the machine tool. Prolonged splashing and hitting of chips will not only shorten the service life of the machine tool, but also cause the connection between the tool holder and the machine tool to loosen, which will reduce the stability of the tool holder during operation.

[0004] Therefore, we propose a mechanically stable tool holder mechanism to solve the above problems. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] like Figure 1-5 As shown in the figure, an embodiment of the present invention provides a mechanically stable tool holder mechanism, including a tool holder assembly 10. The tool holder assembly 10 includes a first connecting plate 1, a connecting head 2, a second connecting plate 3, and a mounting head 4. A telescopic connecting assembly 5 is provided between the first connecting plate 1 and the second connecting plate 3. A protective assembly 6 is provided on the second connecting plate 3. The telescopic connecting assembly 5 is used to adjust the length of the tool holder assembly 10, and the protective assembly 6 is used to block the debris cut by the connected cutting tool of the tool holder assembly 10.

[0028] like Figure 3 As shown, the protective component 6 includes a first threaded ring 601 fixedly mounted on the second connecting plate 3. A limiting ring 606 is fixedly mounted on the lower end face of the first threaded ring 601. A second threaded ring 602 is sleeved on the first threaded ring 601, and the second threaded ring 602 is threadedly connected to the first threaded ring 601. The lower end face of the second threaded ring 602 rests on the upper end face of the limiting ring 606. A protective baffle 603 is fixedly mounted on the second threaded ring 602. A guide ring 604 is fixedly mounted on the end of the protective baffle 603 away from the second threaded ring 602. A plurality of guide plates 605 are sequentially fixedly mounted on the lower end face of the protective baffle 603.

[0029] By setting the protective component 6, it is possible to prevent the chips generated by the tool connected to the tool holder assembly 10 from hitting the connection between the mounting head 4 and the machine tool when the tool holder assembly 10 is working. Long-term splashing and hitting at the connection between the mounting head 4 and the machine tool will not only shorten the service life of the machine tool, but also cause the connection between the mounting head 4 and the machine tool to become loose, which will reduce the stability of the tool holder assembly 10 during operation.

[0030] like Figure 4 and Figure 5 As shown, the telescopic connection assembly 5 includes a first connecting post 501 fixedly disposed on the lower end face of the first connecting plate 1 and a second connecting post 502 fixedly disposed on the upper end face of the second connecting plate 3. The lower end face of the first connecting post 501 has a receiving groove 503. The outer wall surface of the second connecting post 502 has multiple slots 504, each slot 504 containing a compression spring 505. A positioning rod 506 is inserted into each slot 504, with one end of the compression spring 505 fixedly connected to the positioning rod 506 inserted into the slot 504. The outer wall surface of the first connecting post 501 has multiple sets of positioning holes 507, each set containing multiple holes 507 arranged vertically, with the positions of the multiple positioning holes 507 corresponding to the positions of the multiple slots 504. The receiving groove 503 has multiple limiting grooves 508, which correspond to the positions of multiple sets of positioning holes 507. A limiting ring 509 is fixedly provided at the bottom inner side of the receiving groove 503, and a limiting block 510 is fixedly provided at the top of the second connecting post 502. The limiting block 510 and the second connecting post 502 are both inserted into the receiving groove 503, and the outer diameter of the limiting block 510 is adapted to the inner diameter of the receiving groove 503.

[0031] The length of the tool holder assembly 10 can be adjusted by setting the telescopic connecting component 5, which can increase the range of tools that the tool holder assembly 10 can be used with.

[0032] The connector 2 is fixedly disposed on the upper end face of the first connecting plate 1, the second connecting plate 3 is located below the first connecting plate 1, and the mounting head 4 is fixedly disposed on the lower end face of the second connecting plate 3. The mounting head 4 has a mounting hole, through which the tool can be fixedly connected to the mounting head 4.

[0033] The working principle of this practical application is as follows:

[0034] When using this device, insert the bolt into the mounting hole on the mounting head 4, then insert one end of the tool into the mounting head 4, and then fix the tool to the mounting head 4 by rotating the bolt. Then connect the connector 2 to the machine tool. The machine tool drives the tool and the limiting ring 606 on the tool holder assembly 10 to rotate. The rotating tool performs chip cutting on the workpiece. When the chips from the tool fly upwards, the chips will fly onto the lower end face of the protective baffle 603. The rotating protective baffle 603 will centrifuge the chips that fly onto it, thereby guiding the chips onto the machine tool's worktable under the guidance of the protective baffle 603 and the guide ring 604. This can prevent the flying chips from hitting the connection between the mounting head 4 and the machine tool. Prolonged splashing and slapping will not only shorten the service life of the machine tool, but also cause the connection between the mounting head 4 and the machine tool to loosen, which will reduce the stability of the tool holder assembly 10 during operation. If it is necessary to adjust the length of the tool holder assembly 10, press the positioning rod 506 on the first connecting post 501 at the same time. The positioning rod 506 will be moved towards the bottom of the groove 504 under force. When one end of the positioning rod 506 moves into the limiting groove 508 in the receiving groove 503, pull up or down or press down on the first connecting plate 1 until the positioning rod 506 on the second connecting post 502 passes through the adjacent positioning hole 507. This completes the length adjustment of the tool holder assembly 10. If the adjusted length is not enough, continue to adjust in the above way.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
