Description

Technical Field

[0001] This utility model relates to the field of machine tool dust cover technology, and in particular to a machine tool protective cover with good dust protection effect. Background Technology

[0002] CNC machine tools, short for numerical control machine tools, are automated machine tools equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, and input them into the CNC device via an information carrier. 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 dimensions required by the drawings.

[0003] Traditional CNC machine tool protective covers are typically used to prevent the splashing of cutting chips and coolant within the machining area. However, existing machine tool protective covers lack locking mechanisms, and vibrations generated during machining can easily cause the protective cover to move and create openings. This allows chips and coolant from the machining area to easily splash outside the machine tool, resulting in poor protection. Furthermore, dust tends to accumulate on the top of the protective cover, and its height makes it difficult to clean, further complicating dust prevention. Therefore, a machine tool protective cover with better dust prevention is needed to meet these requirements. Utility Model Content

[0004] The purpose of this invention is to provide a machine tool protective cover with good dustproof effect to solve the problems mentioned in the background art.

[0012] The beneficial effects of this utility model are:

[0013] In this invention, the connection between the connecting rod and the scraper allows the protective cover to slide and move, generating friction between the scraper and the cover, thereby cleaning the dust accumulated on the top of the protective cover.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-6 A dustproof machine tool protective cover includes a CNC machine tool 1 and a protective cover 2. The protective cover 2 is slidably connected to the CNC machine tool 1. A connecting rod 3 is provided on the CNC machine tool 1. The connecting rod 3 is arranged in an L-shape. A scraper 4 is movably connected to the bottom end of the horizontal section of the connecting rod 3. The bottom end of the scraper 4 contacts the top end of the protective cover 2. A handle 5 is connected to the outer side of the protective cover 2. A slide rod 6 is slidably connected to the protective cover 2 at the handle 5. A connecting plate 7 is provided at one end of the slide rod 6. The connecting plate 7 is arranged inside the handle 5. An insertion rod 8 is connected to the other end of the slide rod 6. The insertion rod 8 is arranged inside the protective cover 2. A slot 9 is opened on the end of the insertion rod 8 away from the inside of the protective cover 2. A slot 10 is opened on the end of the CNC machine tool 1 that contacts the end of the protective cover 2. A positioning pin 11 is connected to the side wall of the slot 10 near the inside of the CNC machine tool 1. The positioning pin 11 is inserted into the slot 10.

[0024] The arrangement between the connecting rod 3 and the scraper 4 allows the protective cover 2 to rub against the scraper 4 during each sliding motion, thus cleaning the dust accumulated on the top of the protective cover 2 and avoiding manual cleaning. This also improves the dustproof effect of the protective cover 2. The cooperation between the connecting plate 7, the slide rod 6, the insert rod 8, the slot 9, the slot 10, and the positioning pin 11 provides a locking effect for the protective cover 2 to close on the CNC machine tool 1, thereby preventing the protective cover 2 from moving and opening during part processing and effectively preventing the splashing of cutting chips and cutting fluid in the processing area of ​​the CNC machine tool 1.

[0025] Specifically, in this embodiment, guide rails 12 are provided on the top and front ends of the CNC machine tool 1, and the bottom and top ends of the protective cover 2 are extended. The extended parts are slidably connected to the guide rails 12 at the corresponding positions, thereby improving the overall connection between the protective cover 2 and the CNC machine tool 1 and preventing the protective cover 2 from falling off.

[0026] Specifically, in this embodiment, the protective cover 2 is provided with an observation window 13, and the CNC machine tool 1 is provided with a scraper 14. The scraper 14 is arranged in the shape of the inner side of the protective cover 2, and the top of the scraper 14 contacts the inner side of the protective cover 2. The sliding of the protective cover 2 and the relatively stationary scraper 14 generate friction to clean the cutting debris and cutting fluid splashed inside the protective cover 2, and improve the cleaning effect inside the observation window 13 to ensure the clarity of observation.

[0027] Specifically, in this embodiment, the horizontal section of the connecting rod 3 is connected to the same side of the scraper 4 near the closed state of the protective cover 2 via a hinge 15, thereby enabling the scraper 4 to rotate. This restricts the rotation of the scraper 4 when the protective cover 2 is open, scraping the dust on top of the protective cover 2 into the working area of ​​the CNC machine tool 1. When the protective cover 2 is closed, the friction between it and the scraper 4 allows the scraper 4 to rotate, reducing the friction between the scraper 4 and the protective cover 2 and preventing dust from accumulating on the top of the CNC machine tool 1.

[0028] Specifically, in this embodiment, a spring 16 is connected to the inner side of the handle 5. The spring 16 is connected to the connecting plate 7. The elastic force of the spring 16 improves the stability of the insertion between the slot 9 of the insertion rod 8 and the positioning pin 11 of the slot 10.

[0029] Specifically, in this embodiment, the end of the insertion rod 8 near the opening of the slot 10 is inclined, so that the insertion rod 8 can automatically move and be inserted when the protective cover 2 slides closed.

[0030] Specifically, in this embodiment, a cover 17 is provided on the inner side of the protective cover 2. The cover 17 is arranged on the outer side of the insert rod 8. A movable groove 18 is provided at one end of the cover 17. The insert rod 8 is slidably connected in the movable groove 18 to improve the protection effect on the insert rod 8 and prevent the cutting fluid from seeping out from the gap where the slide rod 6 slides.

[0031] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
