[0002] The multifunctional modular CNC lathe is an efficient, flexible and highly automated machine tool that is capable of multi-axis and multi-tool simultaneous processing, which means that it can perform different processing operations at multiple positions at the same time, greatly improving production efficiency. This type of lathe is usually based on serialized and standardized general components combined with a small number of special components, which gives them greater flexibility in design and manufacturing. It combines the advantages of CNC technology and modular machine tools and is suitable for large-scale production and processing of complex parts.

[0003] During the operation of a CNC lathe, the installation and adjustment of the tool are key steps to ensure machining accuracy and efficiency. Due to the size differences of different tools, operators often need to add or remove shims under the tool to adjust the height of the tool tip in order to adapt to different machining requirements. However, this process is often performed manually and may involve repeated trial and error, resulting in a long tool setting time, which affects the overall production efficiency. Therefore, a multifunctional combined CNC lathe tool holder assembly is proposed to solve the above problems. Utility Model Content

[0025] See also Figure 1-3 The multifunctional combined CNC lathe tool rest assembly comprises a lathe tool rest body 1 and a mounting box 2, wherein an adjustment mechanism 3 is arranged between the inside and the top of the mounting box 2.

[0026] In this embodiment, the adjustment mechanism 3 includes a protective box 301, a servo motor 302, a bidirectional threaded rod 303, a limiting rod 304, a movable seat 305, a movable rod 306 and a connecting piece 307. The protective box 301 is fixedly installed on the right side wall of the installation box 2, and the servo motor 302 is fixedly installed inside the protective box 301. The bidirectional threaded rod 303 extending to the inside of the installation box 2 is fixedly installed at the output shaft of the servo motor 302. A limiting rod 304 located on the lower side of the bidirectional threaded rod 303 is fixedly installed between the left and right inner walls of the protective box 301. The movable seat 305 is threadedly connected between the two ends of the outer surfaces of the bidirectional threaded rod 303 and the limiting rod 304. The tops of the two movable seats 305 are rotatably installed with movable rods 306, and the tops of the two movable rods 306 are rotatably installed with connecting pieces 307.

[0027] In this embodiment, a bearing seat is arranged on the left inner wall of the installation box 2 .

[0028] It should be noted that the bearing seat is used to support and position one end of the bidirectional threaded rod 303 to ensure that it can rotate smoothly and accurately. By providing a protective box 301 on the outer surface of the servo motor 302, the protective box 301 can prevent external dust, iron filings and other foreign matter from entering the servo motor 302, thereby avoiding wear or damage to the mechanical parts of the servo motor 302. In harsh environmental conditions, such as humidity, liquid spraying, etc., the protective box 301 can provide additional protection to ensure the normal operation of the servo motor 302.

[0029] In this embodiment, the top of the installation box 2 is provided with openings adapted to the two movable rods 306 , and one end of the two movable rods 306 passes through the openings and extends to the bottom of the connecting piece 307 .

[0030] It should be noted that, by providing an opening, the two movable rods 306 can be connected to the bottom of the connecting piece 307, and the movable rod 306 can move left and right in the opening, so as to adjust the height of the tool tip through the two connecting pieces 307, thereby solving the above-mentioned problem that due to the size difference of different tools, the operator often needs to add or remove gaskets under the tool to adjust the height of the tool tip in order to adapt to different processing requirements; however, this process is often performed manually and may involve repeated trial and error, resulting in a long tool setting time, thereby affecting the overall production efficiency.

[0031] In this embodiment, a power supply is provided on the left side of the installation box 2 , and the power supply is electrically connected to the servo motor 302 .

[0032] Specifically, the power supply provides the necessary power to the servo motor 302 so that it can operate. The servo motor 302 completes the changes in speed, torque and direction by receiving pulse instructions from the PLC or other control systems, thereby achieving the adjustment of the tool tip.

[0033] The two connecting members 307 each include a connecting block 401 rotatably mounted on the top of the movable rod 306 , and extension pieces 402 are fixedly mounted on the front and rear side walls of the two connecting blocks 401 , and mounting rods 403 are threadedly connected to the interiors of the two extension pieces 402 .

[0034] It should be noted that in order to facilitate the fixing of the adjustment mechanism 3 and the lathe tool holder body 1 together, during installation, two threaded holes are opened at both ends of the bottom of the lathe tool holder body 1, the two extension pieces 402 are aligned with the threaded holes, and the mounting rod 403 is screwed into the threaded holes to achieve fixation between the two.

[0035] It should be noted that after the above scheme is adopted in this scheme, the structures and installation methods not described in the description can adopt conventional structures on the market.

[0036] Working principle: After fixing the tool on the lathe tool holder body 1, the mounting rod 403 is passed through the extension piece 402 and screwed into the threaded hole reserved at the bottom of the lathe tool holder body 1. When adjusting the height of the tool tip, the bidirectional threaded rod 303 is first driven to rotate by the servo motor 302. Under the limit of the limit rod 304, the rotation of the bidirectional threaded rod 303 drives the two movable seats 305 to move relative to or in opposite directions. The two movable seats 305 drive the two movable rods 306 to rotate. The rotation of the two movable rods 306 drives the two connecting parts 307 to move up and down, thereby driving the lathe tool holder body 1 to move up and down, and then adjusting the tool tip to a suitable height.

[0037] The beneficial effects of the above embodiments are:

[0038] The multifunctional combined CNC lathe tool rest assembly is provided with an adjustment mechanism 3. Under the action of a connecting piece 307, two connecting blocks 401 can be fixed to the bottom of the lathe tool rest body 1 through a mounting rod 403. The height of the lathe tool rest body 1 can be automatically adjusted through the cooperation of a servo motor 302, a bidirectional threaded rod 303, a limit rod 304, a movable seat 305 and a movable rod 306, thereby changing the height of the tool to adapt to different processing requirements. In addition, a detachable structure is provided between the lathe tool rest body 1 and the mounting box 2, so that the maintenance and replacement of the tool rest becomes more convenient and can be flexibly disassembled according to usage requirements.

[0039] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
