[0036] ​In order to make the person skilled in the art better understand the technical scheme of the present application, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor shall belong to the scope of protection of the present application.

[0037] As described in the background, it is time-consuming to replace the tool, which affects the production efficiency of products.

[0038] In order to solve this technical problem, the present application provides a quick change CNC tool which is applied to product processing.

[0039] Specifically, please refer to Figures 1-2 The quick change CNC tool specifically comprises:

[0040] A tool head 1, the end of the tool head 1 is provided with a tool connecting rod 2, which can be used to connect with the CNC machine tool shaft;

[0041] An installation limiting part is arranged on the outer surface of the tool connecting rod 2, and the installation limiting part cooperates with the CNC machine tool shaft to fix the tool head 1 on the CNC machine tool shaft;

[0042] The outer surface of the installation limiting part is provided with a plurality of tool mounting clamping grooves, which can limit the installation angle and position of the tool head 1.

[0043] The quick change CNC tool provided by the present application sets an installation limiting part on the outer surface of the tool connecting rod 2, and sets a plurality of tool mounting clamping grooves on the installation limiting part. When the CNC tool is replaced, the tool mounting clamping grooves cooperate with the clamp of the CNC machine tool shaft, thereby limiting the installation angle and depth.

[0044] In order to make the person skilled in the art better understand the technical scheme of the present application, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor shall belong to the scope of protection of the present application.

[0045] It should be noted that the embodiments in the present application and the features and technical solutions in the embodiments can be combined with each other without conflict.

[0046] It should be noted that like reference numerals and characters refer to like items throughout the drawings and that once an item is defined in one drawing, it is not necessary to further define and explain it in the subsequent drawings.

[0047] Embodiment 1

[0048] Please refer to Figures 1-2 A quick conversion CNC tool includes a tool head 1 and a mounting limiting part; wherein the end of the tool head 1 is provided with a tool connecting rod 2, which can be used to connect with the CNC machine tool shaft. The mounting limiting part is arranged on the outer surface of the tool connecting rod 2, and the mounting limiting part cooperates with the CNC machine tool shaft to fix the tool head 1 on the CNC machine tool shaft. The outer surface of the mounting limiting part is provided with a plurality of tool mounting clamping grooves, which can limit the installation angle and position of the tool head 1.

[0049] Please refer to Figure 1 The outer surface of the tool connecting rod 2 and the mounting limiting part is provided with an annular clamping groove 4, which is recessed on the surface of the mounting limiting part of the tool connecting rod 2. Thus, the outer surface of the tool connecting rod 2 and the mounting limiting part has a obvious recessed groove, which is used to cooperate with the inner part of the CNC machine tool shaft to improve the stability of the fixing. Avoid the depth change of the tool head 1 in the process of machining. In order to better use the annular clamping groove 4, the inner part of the CNC machine tool shaft is preferably provided with a protrusion matched with the annular clamping groove 4 to clamp the annular clamping groove 4.

[0050] The quick conversion CNC tool provided in embodiment 1 is further optimized, specifically, as shown in Figures 1-2 The mounting limiting part includes a limiting column 3, the outer surface of the limiting column 3 is provided with a plurality of positioning groove blocks 5, and a clamping groove is arranged between two adjacent positioning groove blocks 5, which can cooperate with the inner part of the CNC machine tool shaft to limit the tool head 1.

[0051] Through the above structure design, the limiting column 3 can increase the strength of the tool connecting rod 2. A plurality of positioning groove blocks 5 are arranged on the outer surface of the limiting column 3, and a clamping groove is arranged between two adjacent positioning groove blocks 5 to form a tool mounting clamping groove, which is used to limit the depth and angle of the tool head 1 after installation. And the positioning groove block 5 can increase the friction force of the outer surface of the tool connecting rod 2. Avoid that the CNC machine tool shaft firmly fixes the tool connecting rod 2 and the limiting column 3 to cause the tool head 1 to rotate and affect the machining precision in the process of machining.

[0052] To further improve installation accuracy, the outer surface of the mounting limit part is also marked with perpendicularity marks 7, which are set on the outer surface of each vertically distributed positioning slot 5. During tool changing, the depth of the new tool can be clearly determined based on the degree of the markings 7. This avoids inaccurate machining due to excessive tool installation or collision due to insufficient tool installation. It effectively improves safety and reduces tool setting and machine adjustment time.

[0053] Example 2

[0054] The quick-change CNC tooling provided in Embodiment 1 or 2 is further optimized, such as... Figures 3-4 As shown, the limiting post 3 is a metal cylinder, and its inner diameter is adapted to the outer diameter of the tool connecting rod 2. The limiting post 3 and the tool connecting rod 2 are fixed together in a separable manner. Specifically, the outer surface of the tool connecting rod 2 is provided with an external thread 8, and the inner wall of the limiting post 3 is provided with an internal thread 9. The external thread 8 and the internal thread 9 are adapted to each other.

[0055] To improve applicability and reduce manufacturing costs, an external threaded portion 8 can be provided on the tool connecting rod 2 of the existing tool tip 1, and an internal threaded portion 9 can be provided on the inner wall of the limiting post 3. The limiting post 3 is installed through the threaded connection between the external threaded portion 8 and the internal threaded portion 9. Based on this method, the effect of quick tool replacement can be achieved by modifying the existing tool.

[0056] In practice, a gap is left between the bottom of the external threaded part 8 and the top of the cutting tool head 1, and a gap is left between the bottom of the internal threaded part 9 and the bottom of the limiting post 3. When the external threaded part 8 and the internal threaded part 9 are connected, if a small amount of debris is trapped inside the suspended external threaded part 8 and the internal threaded part 9, the debris will be squeezed to the bottom of the external threaded part 8 at the top of the cutting tool head 1 during installation. This prevents the cutting tool connecting rod 2 and the limiting post 3 from being unable to connect completely, thus avoiding unstable connection and installation difficulties, and also prevents changes in the length of the cutting tool itself.

[0057] To improve stability and ease of installation and removal of the limiting post 3, a vertical groove 6 is provided on the outer surface of the mounting limiting part. The vertical groove 6 is arranged along the axial direction of the limiting post 3. There are four vertical grooves 6, which are equidistantly distributed on the outer surface of the limiting post 3 and extend through both the upper and lower ends of the limiting post 3. The vertical grooves 6 can cooperate with the clamps on the CNC tool spindle to improve the stability of the tool being clamped. The installation position of the tool tip 1 is limited by the vertical grooves 6 and the slider inside the CNC tool spindle. At the same time, when installing and removing the limiting post 3, the vertical grooves 6 can be used with a wrench to rotate the limiting post 3, improving the convenience of installation and removal.

[0058] Example 3

[0059] The quick change CNC cutter provided in each of the above embodiments is further optimized, like Figure 1 As shown, the length of the installation limiting part is greater than half of the length of the cutter connecting rod 2, and the length of the installation limiting part is not more than three quarters of the length of the cutter connecting rod 2. By setting the length of the installation limiting part, the strength of the cutter connecting rod 2 can be improved while the cutter is easily installed. The length of the installation limiting part is not more than the length of the cutter connecting rod 2, so that the diameter of the cutter installation place changes from small to large, and the small head is more easily inserted into the inside of the CNC cutter shaft for installation.

[0060] The use process of the quick change CNC cutter provided by the utility model is as follows:

[0061] The outer threaded part 8 is arranged on the cutter connecting rod 2 of all spare cutters, and the corresponding limiting column 3 is configured according to the number of spares;

[0062] The limiting column 3 is firmly installed on the cutter connecting rod 2, and when initially processing, the depth of cutter installation is determined according to the marker mark 7, and the installation angle of the cutter is determined according to the angle of the vertical groove 6;

[0063] When the cutter needs to be replaced, the original cutter is disassembled, and the new cutter is installed according to the installation parameters of the original cutter. After the new cutter is installed, it only needs to be determined that the cutter is firmly fixed, and there is no need to adjust the parameters of the CNC machine tool and the cutter, which improves the convenience of tool changing.

[0064] In the utility model, unless otherwise specified and limited, the terms "installation", "connection", "connection", "fixing" and the like should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected or in communication with each other; it can be directly connected, or it can be indirectly connected through an intermediate medium, it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise specified. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific situation.

[0065] Obviously, the above-described embodiments are only a part of the embodiments of the present application, rather than all the embodiments, and the preferred embodiments of the present application are given in the drawings, but do not limit the patent scope of the present application. The present application can be realized in many different forms, and conversely, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.
