Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, specifically to a chip-proof tool drive mechanism. Background Technology

[0002] A CNC machine tool is an automated machine tool equipped with a program control system. After processing, the CNC device sends out various control signals to control the machine tool's movements, automatically machining parts according to the shape and size required by the drawings. CNC machine tools have effectively solved the problem of machining precision, small batches, and multiple varieties of parts, representing the development direction of modern machine tool control technology, and are a typical mechatronics product.

[0003] A search revealed that the multi-axis vertical CNC machine tool disclosed in application number CN202210661616.8 includes a machine base, a multi-axis switching mechanism, a multi-axis drive platform, and a protective cover assembly fixedly mounted on the surface of the multi-axis drive platform. A lifting axis seat is fixedly mounted on the top surface of the machine base, and a working head is slidably mounted on the surface of the lifting axis seat. The multi-axis switching mechanism is fixedly mounted on the bottom surface of the working head and is connected to the output end of the working head. The multi-axis drive platform is fixedly mounted on the surface of the machine base. However, the chips generated by the working head during machining are prone to splashing and adhering to the slide rails of the lifting axis seat, causing the working head to slide unevenly on the lifting axis seat.

[0004] In view of this, this case involves in-depth research into the aforementioned issues, which led to the formation of this case. Utility Model Content

[0010] Furthermore, the tool slide saddle includes a sleeve seat, a tool sleeve, and a sliding control motor; the sleeve seat is fixedly sleeved on the through hole, the tool sleeve is connected to the sleeve seat through a second sliding assembly, the sliding control motor is fixedly installed at the end of the tool sleeve, and the sliding control motor is connected to the sleeve seat through a second lead screw assembly. The sliding control motor drives the tool sleeve to slide in the sleeve seat to move closer to or away from the workpiece.

[0011] Furthermore, the second sliding assembly includes a second slide rail fixed to both sides of the outer wall of the tool sleeve and a plurality of second sliders fixed to both sides of the inner wall of the sleeve seat. The tool sleeve slides along the inner wall of the sleeve seat through the cooperation of the second slide rail and the plurality of second sliders.

[0012] Furthermore, the second lead screw assembly includes a fixed seat fixed to the top of the sleeve seat, a second lead screw nut, a limiting block, and a second lead screw fixedly sleeved inside the fixed seat.

[0015] The advantages of this utility model are as follows: the chip-proof tool drive mechanism seals the inner cavity and the first sliding assembly by setting a protective component between the slide frame and the slide plate, which can prevent chips generated during tool processing from splashing onto the tool slide saddle and the first sliding assembly. This can effectively prevent the tool slide saddle and the first sliding assembly from jamming due to chips, and reduce the failure rate and cleaning frequency of the tool drive mechanism.

It includes a vertical slide 1 and at least one tool saddle 2, the end of which is used to mount a turning head or milling head. The vertical slide 1 includes a slide frame 11, a slide plate 12, a protective component 13, and a longitudinal drive mechanism 14 that drives the slide plate 12 to move up and down along the slide frame 11.
