Description

Technical Field

[0001] The utility model relates to the technical field of CNC forming grinders, in particular to a CNC forming grinder protective cover with a self-cleaning function. Background Art

[0002] A CNC grinding machine is a machine tool that uses abrasive tools through CNC technology to grind the surface of a workpiece. Most grinders use high-speed rotating grinding wheels for grinding, while a few use other grinding tools such as oilstones and sanding belts and free abrasives for processing, such as honing machines, super-finishing machines, belt grinders, grinders and polishing machines. During the grinding operation, a protective cover is required to protect the control panel.

[0003] The existing CNC forming grinder protective cover uses multiple sets of overlapping shells to protect the positions of the output devices on both sides of the control panel. The grinder will splash some high-temperature debris during grinding, and the debris will adhere to the surface of the protective cover, causing partial oxidation of the protective cover. The normal cleaning method can only be cleaned by retracting the protective cover. However, when the protective cover retracts, there will be a dead corner that cannot be cleaned by the upper protective cover, and the top protective cover cannot be cleaned.

[0004] Therefore, a CNC forming grinder protective cover with self-cleaning function is proposed. Utility Model Content

[0005] The purpose of the present utility model is to provide a CNC forming grinder protective cover with a self-cleaning function to solve the problem that the usual cleaning method proposed in the above background technology can only be cleaned by retracting the protective cover, and there will be a dead corner when the protective cover is retracted, which cannot be cleaned by the upper protective cover, and the topmost protective cover cannot be cleaned.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: it includes an operating table, the top of the operating table is slidably connected to a protective cover body, a rotating groove is opened on the opposite side of the operating table, a cleaning screw is rotatably connected inside the rotating groove, a sliding block is rotatably connected outside the cleaning screw, the sliding block is slidably connected inside the rotating groove, a scraper is fixedly connected to one side of the sliding block, the scraper is slidably connected to the top of the protective cover body, one end of the cleaning screw is fixedly connected to a spur gear, the protective cover body is fixedly connected to a rack close to the spur gear, and a cleaning assembly is provided on the top of the operating table, and the cleaning assembly is used to clean the protective cover body.

[0007] Preferably, the cleaning assembly includes a cleaning box, a spray head is fixedly connected to the side of the cleaning box close to the protective cover body, and an injection port is fixedly connected to the side of the cleaning box away from the spray head.

[0008] Preferably, the cleaning screw is fixedly connected to a rotating sleeve at one end away from the spur gear, the rotating sleeve is rotatably connected to a transmission belt on the outside, the transmission belt is rotatably connected to a driving bevel gear on the inside away from the rotating sleeve, and a downward pressure component is provided inside the cleaning box near the driving bevel gear, and the downward pressure component is used to pressurize and squeeze out the cleaning liquid inside the cleaning box.

[0009] Preferably, the down-pressing assembly includes a driven bevel gear, which is meshed with one side of the driving bevel gear. A lifting screw is fixedly connected to the inside of the driven bevel gear, and a down-pressing plate is rotatably connected to the outside of the lifting screw. A limiting rod is slidably connected to the inside of the down-pressing plate away from the position of the lifting screw.

[0010] Preferably, the top of the lifting screw is rotatably connected to a fixing plate, the top of the fixing plate is rotatably connected to a support shaft, and the end of the support shaft away from the fixing plate is rotatably connected to the inside of the driving bevel gear.

[0013] Preferably, a grinding tool is provided above the fixing platform, and the ratchet is made of a soft plastic rebound material.

[0014] Beneficial effects of the utility model:

[0015] 1. When the utility model is polished by the grinding tool, the fixed table moves, thereby pushing the protective cover body to shrink. When the protective cover body shrinks, it drives the rack to push the meshing gear to rotate, thereby driving the cleaning screw to rotate, allowing the sliding block to slide inside the rotating groove, so that the scraper can clean the dead corners of the protective cover body, solving the problem of using the extension and contraction of the protective cover body to clean the surface of the protective cover body, resulting in some dead corners that cannot be cleaned, and improving the cleaning effect of the protective cover body.

[0016] 2. The utility model drives the ratchet to push the pushing block when the cleaning screw rotates, thereby driving the rotating sleeve to rotate, and the rotating sleeve drives the protective cover body and the driving bevel gear. The driving bevel gear will drive the support shaft and the lifting screw to rotate, thereby controlling the lower pressure plate to rise and fall inside the cleaning box, thereby squeezing the cleaning liquid inside the cleaning box from the spray head and cleaning the highest position of the protective cover body, solving the problem that the highest point of the protective cover body could not be cleaned in the past, resulting in a reduced service life of the protective cover body, and improving the service life of the protective cover body.

[0026] like Figures 1 to 5 As shown, a specific embodiment of the present invention provides a CNC forming grinder protective cover with a self-cleaning function, including an operating table 3, a protective cover body 1 being slidably connected to the top of the operating table 3, a rotating groove 4 being opened on the opposite side of the operating table 3, a cleaning screw 6 being rotatably connected inside the rotating groove 4, a sliding block 7 being rotatably connected outside the cleaning screw 6, the sliding block 7 being slidably connected inside the rotating groove 4, a scraper 8 being fixedly connected to one side of the sliding block 7, the scraper 8 being slidably connected to the top of the protective cover body 1, one end of the cleaning screw 6 being fixedly connected to a spur gear 5, a rack 2 being fixedly connected to the side of the protective cover body 1 close to the spur gear 5, a cleaning assembly being provided on the top of the operating table 3, the cleaning assembly being used to clean the protective cover body 1, the cleaning assembly comprising a cleaning box 17, a spray head 18 being fixedly connected to the side of the cleaning box 17 close to the protective cover body 1, and an injection port 19 being fixedly connected to the side of the cleaning box 17 away from the spray head 18.

[0027] By adopting the above technical solution, the utility model enables the protective cover body 1 to be extended and retracted on the top of the operating table 3, and the protective cover body 1 to be contracted, which will drive the rack 2 to push the meshing gear 5 to rotate, and the gear 5 will drive the sliding block 7 to slide inside the rotating groove 4, and the sliding block 7 will drive the scraper 8 to scrape and clean the dead corners of the surface of the protective cover body 1. At this time, the cleaning box 17 is started, and the cleaning liquid inside the cleaning box 17 can be sprayed from the spray head 18, so that the highest layer of the surface of the protective cover body 1 can be cleaned. After the cleaning liquid inside the cleaning box 17 is discharged, the cleaning liquid can be injected into the cleaning box 17 through the injection port 19, thereby achieving the surface cleaning effect of the highest layer of the protective cover body 1.

[0028] Specifically, such as Figure 2 and Figure 5It is shown that the cleaning screw 6 is fixedly connected to the rotating sleeve 9 at one end away from the spur gear 5, and the rotating sleeve 9 is rotatably connected to the transmission belt 10 on the outside. The transmission belt 10 is rotatably connected to the driving bevel gear 11 at a position away from the rotating sleeve 9. A down-pressing component is provided inside the cleaning box 17 near the driving bevel gear 11. The down-pressing component is used to pressurize and extrude the cleaning liquid inside the cleaning box 17. The down-pressing component includes a driven bevel gear 14, which is meshed with one side of the driving bevel gear 11. The driven bevel gear 14 is fixedly connected to the inside of the driven bevel gear 14, and the lifting screw 15 is rotatably connected to the lower pressure plate 16 on the outside. The lower pressure plate 16 is slidably connected to the limit rod 20 at the position away from the lifting screw 15. The top of the lifting screw 15 is rotatably connected to the fixed plate 13, and the top of the fixed plate 13 is rotatably connected to the support shaft 12. The end of the support shaft 12 away from the fixed plate 13 is rotatably connected to the inside of the driving bevel gear 11.

[0029] The cleaning screw 15 is driven by the driving bevel gear 11, and the driving bevel gear 11 is supported by the support shaft 12 and the fixing plate 13, and the driving bevel gear 11 also drives the driven bevel gear 14 to rotate, thereby driving the lifting screw 15 to rotate. When the lifting screw 15 rotates, it drives the lower pressure plate 16 to rise and fall along the limit rod 20 to prevent the lower pressure plate 16 from causing friction on the inner wall of the cleaning box 17, and the lower pressure plate 16 can be lowered to squeeze the cleaning liquid inside the cleaning box 17 from the spray head 18 to achieve the cleaning effect. The support shaft 12 is supported inside the driving bevel gear 11, and the other end of the support shaft 12 is connected to the fixing plate 13, so that the fixing plate 13 rotates at the top of the lifting screw 15, which can ensure that the driven bevel gear 14 can rotate smoothly, and can also ensure the support effect of the support shaft 12 on the driving bevel gear 11, thereby cleaning the highest point of the outer surface of the protective cover body 1.

[0030] Specifically, such as Figure 1 and Figure 4 As shown, the rotating sleeve 9 is rotatably connected to one side of the operating table 3, and a ratchet 21 is rotatably connected inside the rotating sleeve 9. The ratchet 21 is fixedly connected to one end of the cleaning screw 6. The outside of the ratchet 21 abuts against a push block 23, and the push block 23 is fixedly connected to the inside of the rotating sleeve 9. There are two groups of symmetrical arrangements of the protective cover body 1. A fixed platform 24 is fixedly connected to the opposite side of the protective cover body 1. A grinder 25 is provided above the fixed platform 24. The ratchet 21 is made of a soft plastic rebound material.

[0031] By adopting the above technical solution, the rotation of the cleaning screw 6 can drive the ratchet 21 to rotate inside the rotating sleeve 9, and the ratchet 21 will push the pushing block 23, and then the pushing block 23 drives the rotating sleeve 9 to rotate, thus ensuring that the rotating sleeve 9 can drive the transmission belt 10 to transmit, and the material of the ratchet 21 ensures that it will not be blocked during reverse rotation, so that it can rotate smoothly and will not drive the rotating sleeve 9 to rotate. During forward rotation, the multiple groups of protruding structures of the ratchet 21 contact the pushing block 23, achieving the effect of pushing the rotating sleeve 9 to rotate, and when the rack 2 is withdrawn, it will drive the gear 5 and the cleaning screw 6 to rotate in the opposite direction, and when the cleaning screw 6 is reversed, the ratchet 21 will slide inside the pushing block 23, thus ensuring that the rotating sleeve 9 cannot rotate. If the rotating sleeve 9 cannot rotate, the transmission belt 10 will not drive the lower pressure plate 16 to rise, thereby ensuring the pressurization effect of the lower pressure plate 16 on the cleaning liquid inside the cleaning box 17.
