Detailed Implementation

[0026] 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.

[0027] like Figures 1-8 As shown: A tool magazine's tool head rotation mechanism includes a connecting arm 1 with a back plate 101. The connecting arm 1 is hinged to a frame (not shown) via a hinge block 102. A fixed shaft 103 mounted on the connecting arm 1 is rotatably fitted with a tool head 2 that elastically holds tools 301 via a plurality of tool clips 3 through a bearing 113. Each tool clip 3 is locked and fixed to a tool cover 302 by fasteners (the tool clips 3 are other components of the tool magazine, which can be referred to in the prior art and will not be described in detail here). The tool head 2 can be driven to rotate by a motor 401 and a worm gear 402, thereby switching the appropriate tool to cooperate with the spindle of the drilling machine and participate in the workpiece machining action.

[0028] Furthermore, such as Figures 2-3 As shown, the fixed shaft 103 is provided with a connecting seat 4 that is close to an elongated shape at the end away from the connecting arm 1. The fixed shaft 103 and the middle part of the connecting seat 4 are locked together. The motor 401 and the worm gear 402 are respectively installed at both ends of the connecting seat 4. The two are driven by the laterally arranged synchronous pulley 403 and synchronous belt 404. When the worm gear 402 is driven to rotate by the motor 401, the rotor 5 locked at the end of the cutter head 2 can be driven to rotate by its own rollers 501.

[0029] Specifically, a timing belt cover 405 is provided on the outside of the timing pulley 403 and the timing belt 404. The timing belt cover 405 is fixed to the side of the connecting seat 4, and an avoidance groove 415 is provided on the side of the cover close to the rotor 5 to avoid interference with the rotor 5.

[0030] Furthermore, an outer cover 6 is locked to the front side of the aforementioned connecting seat 4, and a chip baffle 7 is locked to the rear side to prevent machining debris from splashing onto the cutter head 2. The outer cover 6 and the chip baffle 7 together form a chamber to house and protect the motor 401 and the worm gear 402. Simultaneously, the edges of the outer cover 6 and the chip baffle 7 are respectively formed with a rim 601 and a flange 701, and the rim 601 of the outer cover 6 is spaced apart from the cutter cover 302 by a certain gap. Figure 5As shown, due to the presence of the edging 601 and the flange 701, a large concave cavity 9 is formed between the edge of the chamber and the blade cover 302. When the motor 401 and related drive components are being inspected, the hand can grip the edge of the outer cover 6 more stably through the concave cavity, thereby preventing it from impacting other components due to its own weight after being removed.

[0031] Specifically, because the connecting seat 4 used to install the motor 401 and worm gear 402 is locked to the front end of the fixed shaft 103, the front end of the fixed shaft 103 is under heavy load, making the entire drive unit prone to falling. Therefore, a sleeve 8 is fixedly fitted at the boss 201 at the center of the cutter head 2. This sleeve 8 is fitted with a chip baffle 7 locked to the rear side of the connecting seat 4 to prevent machining debris from splashing onto the cutter head 2. If this is done, without affecting the rotation of the tool magazine, the sleeve 8 can provide auxiliary support to the drive part at the front end of the fixed shaft 103 with the help of the chip baffle 7, sharing some of the pressure and thus reducing the aforementioned risk of falling.

[0032] Furthermore, the fixed installation between the above components can be achieved using various types of screws as fasteners.

[0033] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
