These drawings are part of the disclosure of the utility model, which are mainly used to illustrate the embodiments and can be used to explain the operating principle of the embodiments in conjunction with the relevant descriptions in the specification. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the utility model. The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0022] Now, the utility model will be further described in conjunction with the drawings and specific implementation manners.

[0023] Embodiment 1

[0024] Refer to Figures 1 to 3As shown, Embodiment 1 provides a tool magazine cover structure for a numerically controlled machine tool (hereinafter simply referred to as the tool magazine cover structure) for protecting the tool magazine of the numerically controlled machine tool.

[0025] The tool magazine cover structure of this embodiment includes a tool magazine cover 1 for protecting the tool magazine 2. The tool magazine cover 1 has a hollow inner cavity. Observation ports 11 and mounting ports 12 communicating with its inner cavity are respectively provided on the two outer walls of the tool magazine cover 1. Specifically, the observation port 11 is located on the upper side wall of the tool magazine cover 1, and the mounting port 12 is located on the rear side wall of the tool magazine cover 1.

[0026] The mounting port 12 is used for mounting the tool disc 22 of the tool magazine 2, and the inner wall of the mounting port 12 is arranged at an interval around the outer peripheral surface of the tool disc 22. After the tool magazine 2 is installed at the mounting port 12, a part of the tool disc 22 of the tool magazine 2 facing the observation port 11 protrudes out of the observation port 11, so that some of the tools 21 on the tool disc 22 are exposed outside the tool magazine cover 1.

[0027] In this embodiment, the tool magazine cover 1 is a plastic tool magazine cover made of acrylic and is detachably assembled on the housing 3 of the numerically controlled machine tool to facilitate the disassembly and assembly of the tool magazine cover 1 during daily maintenance and servicing of the tool magazine 2. Additionally, as Figure 3 shown, a recessed relief groove 15 is provided on the inner cavity wall of the tool magazine cover 1 facing away from the observation port 11. The relief groove 15 is used for making way for the removal of the tool 21 of the tool magazine 2 during tool change.

[0028] More specifically, as Figure 2 and Figure 3 shown, the inner cavity wall of the tool magazine cover 1 includes an arc-shaped wall body 13 and a front blocking wall body 14 fixedly connected to the front end of the arc-shaped wall body 13 facing away from the tool magazine 2. The rear opening of the arc-shaped wall body 13 facing away from the front blocking wall body 14 is the mounting port 12, and the upper opening of the arc-shaped wall body 13 in its circumferential direction is the observation port 11. At this time, the tool magazine cover 1 is a semi-closed protective cover structure, and the material usage of the tool magazine cover 1 can be reduced, effectively reducing the material cost of the tool magazine cover 1.

[0029] By surrounding the arc-shaped wall body 13 around the outer peripheral surface of the tool magazine 2 to form a blocking wall for blocking the debris splashing up from the machining area, the debris can be blocked outside the tool magazine cover 1, thereby preventing the debris from splashing into the tool magazine 2.

[0030] By setting the tool magazine cover 1 as a semi-closed protective cover structure, debris and other foreign objects can be effectively isolated, thereby preventing the debris generated during machining from splashing into the tool magazine 2. And by making a part of the tool disc 22 of the tool magazine 2 facing the observation port 11 protrude out of the observation port 11, some of the tools 21 on the tool disc 22 are exposed outside the tool magazine cover 1, effectively increasing the visual range of the tool magazine cover 1, and also realizing the replacement of the tool 21 of the tool magazine 2 without removing the tool magazine cover 1 and facilitating the real-time observation of whether the tool 21 of the tool magazine 2 is damaged.

[0031] In another preferred embodiment, as Figure 2 shown, the distance L between the cutter head 22 and the front baffle body 14 is greater than the length of the cutter 21 in the tool magazine 2. Compared with the fully enclosed tool magazine cover 1 in the prior art, the tool magazine cover structure of this embodiment can effectively increase the inner cavity space of the tool magazine cover 1 to facilitate the accommodation of larger-sized cutters 21, that is, it can effectively increase the usage range of the cutter 21 size in the tool magazine 2. For example, the length of the cutter 21 can be longer.

[0032] In another preferred embodiment, as Figure 3 shown, the front baffle body 14 is provided with a perspective window 141 for visually observing the tool magazine 2 in the tool magazine cover 1 to further increase its visual range.

[0033] Further preferably, a flip-up upper cover can also be installed at the observation port 11 of the tool magazine cover 1.

[0035] Embodiment 2 provides a numerical control machine tool, which at least includes the tool magazine cover structure of the numerical control machine tool in Embodiment 1.

[0036] Although the present invention has been specifically shown and described in combination with the preferred embodiments, those skilled in the art should understand that various changes can be made to the present invention in terms of form and details without departing from the spirit and scope of the present invention defined by the appended claims, and all are within the protection scope of the present invention.
