Technical Field

[0001] This utility model relates to the field of cutting tool technology, and specifically to a tool holder that indicates the installation depth. Background Technology

[0002] Machine tools are used extensively in production and processing, and cutting tools are required on these machines. When installing cutting tools, there is a minimum installation depth required, and clamping milling cutters requires exceeding this minimum depth. However, because this minimum installation depth is normally invisible inside the bore, installers currently have to measure both the bore depth and the depth of the milling cutter to be clamped, comparing the two measurements to determine if the tool can be installed—a very inconvenient process.

[0003] Therefore, there is an urgent need to develop a tool holder that indicates the minimum installation depth, making it easy to determine whether the cutting tool can meet the minimum installation depth requirement of the tool holder. Utility Model Content

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or components / elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] The following description, in conjunction with the accompanying drawings, describes a tool holder indicating the installation depth according to an embodiment of the present invention.

[0020] Figure 1 This is a front view of a tool holder indicating the installation depth, provided in one embodiment of the present invention; Figure 2 This is a left view of a tool holder indicating the installation depth, provided in one embodiment of the present invention; Figure 3 This is a top view of a tool holder indicating installation depth provided in one embodiment of the present invention; Figure 4 This is an AA cross-sectional view of a tool holder indicating installation depth provided in one embodiment of this utility model. (See diagram below.) Figure 1-4 As shown, the tool holder indicating the installation depth includes: a connecting part 1 and a tool holder spindle 2 disposed on one side of the connecting part 1; wherein, the connecting part 1 has a locking ring groove 11 in the middle, and locking platforms 12 on the left and right sides of the locking ring groove 11; the outer wall of the tool holder spindle 2 has annular scale lines 21; and the spindle 2 has an installation inner hole 22 at its axis.

[0021] Specifically, the retaining ring groove 11 in the middle of the connecting part 1 forms retaining platforms 12 on both sides of the connecting part 1. When the tool holder is installed on the machine tool, it is connected and installed through the retaining ring groove 11 and the retaining platforms 12. The tool holder spindle 2 is used to install the tool, and the scale line 21 indicates the minimum installation depth. When installing the tool, the tool is placed on the tool holder spindle 2, and the installation depth of the tool is compared with the scale line 21 to determine whether the minimum installation depth requirement is met.

[0022] It should be noted that, as Figure 1-4 As shown, the connecting part 1 and the main body of the tool holder spindle 2 are rotating bodies, and the connecting part 1 and the tool holder spindle 2 are coaxially integrally formed.

[0023] According to the tool holder of this utility model, which indicates the installation depth, it is easy to determine whether the tool meets the minimum installation depth requirement by directly comparing it with the scale line.

[0024] According to one embodiment of the present invention, a pin 3 is also provided on the other side of the connecting part 1.

[0025] Specifically, the pin 3 is used to insert into the mounting components of the machine tool when installing the tool holder, making the tool holder connection more secure.

[0026] According to one embodiment of the present invention, the pin 3 is provided with an insertion inner hole 31 at the axis.

[0027] According to one embodiment of the present invention, the insertion inner hole 31 is connected to the mounting inner hole 22.

[0028] Specifically, the insertion inner hole 31 can further improve the stability of the tool holder installation connection, and on the other hand, it communicates with the mounting inner hole 22, so that the air in the hole can be released when the tool is installed, thus facilitating the installation of the tool.

[0029] It should be noted that, as Figure 1-4 As shown, the pin 3 is a rotating body, and the pin 3, the connecting part 1, and the tool holder spindle 2 are coaxially integrally formed.

[0030] According to one embodiment of the present invention, the snap-fit ​​platform 12 of the connecting part 1 is provided with a snap-fit ​​flat groove 13.

[0031] Specifically, the mounting components of the machine tool can be equipped with pin-type components. When installing the tool holder, the snap-fit ​​groove 13 is used to snap into the pin-type components of the machine tool to restrict the degree of freedom of rotation of the tool holder.

[0032] According to one embodiment of the present invention, the snap-fit ​​groove 13 is closed at one end facing the tool holder spindle 2 and open at the other end.

[0033] Specifically, the snap-fit ​​groove 13 is closed at one end facing the tool holder spindle 2 and mates with the snap-fit ​​ring groove 11, allowing the tool holder to be stably installed in the machine tool; the snap-fit ​​groove 13 is open at the other end, facilitating the insertion of machine tool pin-like components. This design also facilitates the manufacturing of the tool holder, which can be formed in just one milling step, resulting in low production costs.

[0034] According to one embodiment of the present invention, the mounting inner hole 22 includes a first inner hole 221 at the outer end and a second inner hole 222 at the inner end.

[0035] According to one embodiment of the present invention, the radius of the first inner hole 221 is smaller than the radius of the second inner hole 222.

[0036] According to one embodiment of the present invention, the scale line 21 is disposed on the outer wall at the same depth as the junction of the first inner hole 221 and the second inner hole 222.

[0037] Specifically, the tool needs to be fully connected to the first inner hole 221 at the outer end during installation, so the depth of the first inner hole 221 is the minimum installation depth. The depth of the first inner hole 221 is the junction of the first inner hole 221 and the second inner hole 222, so the scale line 21 can be set on the outer wall of the tool holder spindle 2 at the same depth as the junction of the first inner hole 221 and the second inner hole 222.

[0038] The above embodiments are preferred implementations of this application. In addition, this application can be implemented in other ways. Any obvious substitutions without departing from the concept of this application are within the protection scope of this application.
