Description

Technical Field

[0001] This utility model belongs to the field of protection technology for large CNC machine tools, and specifically relates to a protective cover for large CNC machine tools. Background Technology

[0002] CNC machine tool protective covers are crucial devices that protect core components such as machine tool guideways and lead screws from cutting fluid, coolant, and hard particles. They are essential for maintaining equipment accuracy and extending its service life. CNC machine tool protective covers are made of 1.5-4mm thick cold-rolled steel or stainless steel plates, offering high impact resistance and capable of handling movement speeds up to 30m / min.

[0003] Traditional machine tool guards use guide rails for easy opening of the protective doors. However, when the CNC machine tool is in operation, the closed guide rail doors can be shaken open by vibrations, causing metal shavings to fly and potentially posing a hazard to the operator.

[0048] like Figure 1-7 As shown, this embodiment provides a protective cover for a large CNC machine tool, including a cover body and a sliding protective door 10 disposed on the cover body.

[0049] To facilitate smooth sliding of the protective door 10 during opening and closing, a slide rail 50 is fixedly installed on the cover (e.g., by fastening screws or welding) to allow the protective door 10 to slide on the cover. A slider 303 is provided on the end face of the protective door 10 away from the handle, which cooperates with the slide groove of the slide rail 50. The slider 303 of the protective door is installed in the slide groove of the slide rail 50, so that the protective door can slide along the longitudinal direction of the slide rail 50 within the slide groove, enabling the protective door to open and close smoothly.

[0050] In this embodiment, the slider 303 is welded onto the reinforcing frame 301, and the reinforcing frame 301 is made of a 4.5mm thick stainless steel plate bent by a bending machine, so as to wrap the protective door 10 through the reinforcing frame 301, and the reinforcing frame 301 is installed on the protective door 10 by fastening bolts 302.

[0051] Those skilled in the art will understand that a reinforced frame formed by bending 4.5mm thick stainless steel sheet has a tensile strength ≥520MPa and can effectively distribute the stress on the protective door.

[0052] The protective door uses a guide rail design for easy opening. When the CNC machine tool is in operation, the closed guide rail protective door may be shaken open due to vibration, causing metal shavings to fly and potentially posing a hazard to the operator. To prevent accidental opening of the protective door during operation, please refer to [link / reference needed]. Figure 1-7 As shown, a connecting rod 701 is installed on the side end face of the protective door 10 by fastening bolts, and a positioning block 702 is provided on the end face of the connecting rod 701 away from the protective door 10, which is integrally formed with it.

[0053] Furthermore, a positioning seat is fixedly installed on the end face of the cover opposite to the positioning block 702 by fastening screws. The positioning seat has a rectangular groove, and a sliding end 705 that cooperates with it is provided in the rectangular groove. A spring 704 is fixedly connected to the end face of the sliding end 705 away from the positioning block 702, and the other end of the spring 704 is fixedly connected to the inner wall of the rectangular groove of the positioning seat.

[0054] Those skilled in the art should understand that the fixed connection methods in this application can all be common connection methods, such as fastening bolts, welding, etc.

[0055] Furthermore, a positioning groove 703 is provided inside the sliding end 705 away from the spring 704, and the upper and lower end faces of the positioning groove are inclined at an angle of not less than 85°. This ensures that the positioning groove 703 and the positioning block 702 cooperate to lock when engaged.

[0056] In this embodiment, the positioning block 702 that cooperates with the positioning slot 703 is engaged, so that the outer wall of the positioning block 702 is in close contact with the inner wall of the positioning slot 703.

[0057] Furthermore, both the top plate of the positioning block 702 and the positioning slot 703 are provided with insertion holes 707.

[0058] In this embodiment, when the protective door 10 is closed, the positioning block 702 of the protective door 10 extends into the positioning slot 703 to engage. Continuing to push the protective door forcefully pushes the sliding end 705 towards the rectangular slot, and as the sliding end moves towards the rectangular slot, the spring 704 is continuously compressed.

[0059] Furthermore, the positioning seat is internally threaded with a plug rod 706. When the sliding end moves to the corresponding position, the plug rod 706 is rotated so that it is screwed into the insertion hole 707 for threaded connection.

[0060] In this embodiment, the internal thread of the insertion hole 707 is used in conjunction with the external thread of the insertion rod 706 to form a threaded connection, and the threaded hole on the positioning seat is a through hole, which is also used in conjunction with the external thread of the insertion rod 706 to form a threaded connection.

[0061] Those skilled in the art should understand that when the protective door 10 is closed, the positioning block 702 of the protective door 10 extends into the positioning slot 703 for engagement. Continuing to push the protective door further pushes the sliding end 705 towards the rectangular groove. When it reaches the desired position, rotating the insertion rod 706 causes it to pass sequentially from top to bottom through the threaded hole at the top of the sliding end, the threaded hole on the positioning block 702, and finally into the threaded hole of the positioning slot, achieving a threaded connection between the protective door and the cover.

[0062] This utility model has a simple overall structure. A reliable locking mechanism is formed by a positioning block on the protective door and a sliding end on the cover, thereby achieving a lock between the protective door and the cover. This effectively prevents the protective door from accidentally opening due to accidents or vibrations while the CNC machine tool is operating.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not restrictive. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
