Description

Technical Field

[0001] This utility model belongs to the field of engraving and milling machine technology, specifically relating to a five-axis engraving and milling machine. Background Technology

[0002] A carving and milling machine is a type of CNC machine tool. Generally, a carving and milling machine is considered to be a CNC milling machine that uses small cutting tools, high power and high speed spindle motors. The advantage of carving machines is in carving, but they are not capable of handling materials with high hardness. Therefore, the emergence of carving and milling machines can be said to have filled the gap between the two.

[0003] A five-axis CNC milling machine is a high-precision and high-efficiency CNC machining equipment widely used in mold manufacturing, dental prosthesis processing, jewelry making, aerospace, and other fields. Its core advantage lies in achieving high-precision machining of complex curved surfaces and geometric shapes through synchronous control of five axes, thereby significantly improving processing efficiency and product quality. However, the five-axis CNC milling machine process generates dust, metal powder, wood chips, and other impurities, which can harm workers. Therefore, five-axis CNC milling machines typically have internal collection and filtration mechanisms. However, existing five-axis CNC milling machines often lack convenient methods for cleaning the filters within these mechanisms. Therefore, there is an urgent need for a new type of five-axis CNC milling machine.

[0004] A patent with publication number CN215510166U discloses a novel five-axis linkage engraving and milling machine. It includes a first motor, a second motor, fan blades, an air inlet, an axial flow fan housing, filter elements, a dust collection drawer, and a cylindrical eccentric shaft. In operation, the output shaft of the second motor drives the fan blades to rotate, drawing air containing dust and sawdust into the axial flow fan housing through the air inlet. The filter elements filter the air, causing the dust to fall into the dust collection drawer, and the purified air is discharged from the fan outlet. Simultaneously, the first motor is activated, and its output shaft drives the cylindrical eccentric shaft to rotate, causing the axial flow fan housing to reciprocate, thereby increasing the dust collection area of ​​the axial flow fan housing.

[0005] However, the filter discs in the above-mentioned scheme will become clogged during long-term use, and impurities and wood chips will adhere to the surface of the filter discs. This will not only affect the suction force generated by the fan blades, but also affect the subsequent filtration effect of the filter discs, thus having certain limitations in practical use. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model provides a five-axis engraving and milling machine.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A five-axis engraving and milling machine includes an engraving and milling table mounted on a workbench and a main body of the engraving and milling machine. The top of the workbench is both a housing that is slidably positioned and a drive mechanism that drives the housing to slide. A filter plate is fixedly installed inside the housing, and the filter plate divides the interior of the housing into a first chamber and a second chamber that are connected. A scraper is slidably positioned in the first chamber along the vertical direction, and the housing is driven by the scraper through a transmission component. The scraper slides and fits against the filter plate.

[0009] Furthermore, the driving mechanism includes a motor, a threaded rod is rotatably mounted on the worktable in the horizontal direction, the housing is threadedly engaged with the threaded rod, and one side of the housing is slidably attached to the worktable; the motor is fixedly mounted on the worktable, and the output shaft of the motor is coaxially and fixedly connected to one end of the threaded rod.

[0010] Furthermore, both a fan shroud and a fan are fixedly mounted on the housing, with the larger opening of the fan shroud facing the milling table.

[0011] Furthermore, the shroud is directly connected to the first chamber, and the fan is directly connected to the second chamber.

[0012] Furthermore, a collection box is slidably inserted into the first chamber, and the collection box is located below the scraper.

[0013] Furthermore, the transmission component includes a sliding shaft, with the top of the scraper fixedly mounted on the sliding shaft. The top of the sliding shaft slides through the housing and is fixedly mounted on a connecting rod. A spring is sleeved on the outer surface of the sliding shaft, with one end of the spring fixedly connected to the connecting rod and the other end fixedly connected to the housing. In addition, a guide plate is fixedly mounted on the worktable, with an inclined surface on the guide plate. The inclined surface of the guide plate is in contact with the connecting rod for transmission.

[0014] This application has the following beneficial effects:

[0015] During the movement of the housing controlled by the drive mechanism, the scraper will automatically slide downward under the transmission of the transmission components, thereby scraping off the impurities attached to the surface of the filter plate, thus preventing impurities from clogging the filter plate and ensuring the subsequent filtration effect of the filter plate.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: a five-axis engraving and milling machine includes an engraving and milling machine body 2 and an engraving and milling table 3 installed on a worktable 1. The top of the worktable 1 is both limited and slidably equipped with a housing 6, and is also provided with a driving mechanism for driving the housing 6 to slide.

[0025] The drive mechanism includes a motor 4, a threaded rod 5 that rotates horizontally on the worktable 1, a housing 6 that is threadedly engaged with the threaded rod 5, and one side of the housing 6 that slides against the worktable 1; the motor 4 is fixedly installed on the worktable 1, and the output shaft of the motor 4 is coaxially and fixedly connected to one end of the threaded rod 5.

[0026] A filter plate 9 is fixedly installed inside the housing 6, which divides the interior of the housing 6 into a first chamber 16 and a second chamber 17 that are connected. A fan shroud 8 and a fan 7 are both fixedly installed on the housing 6. The larger opening of the fan shroud 8 faces the milling table 3 and the fan shroud 8 is directly connected to the first chamber 16. The fan 7 is directly connected to the second chamber 17.

[0027] The scraper 11 is slidably positioned in the vertical direction within the first chamber 16 and is also slidably inserted into the collection box 10, which is located below the scraper 11. The housing 6 is driven by the scraper 11 through a transmission component, and the scraper 11 slides against the filter plate 9.

[0028] The transmission components include a sliding shaft 12, which is fixedly mounted on the top of the scraper 11. The top of the sliding shaft 12 slides through the housing 6 and is fixedly mounted on a connecting rod 14. A spring 13 is sleeved on the outer surface of the sliding shaft 12, with one end of the spring 13 fixedly connected to the connecting rod 14 and the other end fixedly connected to the housing 6. Additionally, a guide plate 15 is fixedly mounted on the worktable 1. The guide plate 15 has an inclined surface, which engages with the connecting rod 14 in a contact transmission manner.

[0029] Working principle: When it is necessary to clean the impurities generated during the processing of the main body 2 of the engraving and milling machine, the fan 7 is started. The fan 7 generates suction force in the fan hood 8, thereby drawing the air containing impurities into the housing 6 through the fan hood 8. The filter plate 9 filters the air drawn into the housing 6, leaving the impurities in the first chamber 16. The impurities then settle into the collection box 10 under their own gravity, and the filtered air is discharged through the exhaust port of the fan 7.

[0030] During this process, motor 4 is started, and the output shaft of motor 4 drives the threaded rod 5 to rotate in both directions, causing the housing 6 to reciprocate on the worktable 1, thereby increasing the dust collection area of ​​the fan 7, improving dust collection efficiency, and ensuring the working environment.

[0031] Simultaneously, the movement of the housing 6 drives the connecting rod 14 to move synchronously. During this movement, the connecting rod 14 comes into contact with the inclined surface of the guide plate 15. After contact, the connecting rod 14 moves downward along the inclined surface of the guide plate 15. This downward movement of the connecting rod 14 drives the sliding shaft 12 to move downward and compress the spring 13, thereby pushing the scraper 11 downward. The downward movement of the scraper 11 scrapes away the impurities and debris attached to the filter plate 9, causing the scraped debris to fall into the collection box 10 for collection, thus preventing impurities from clogging the filter plate 9 and ensuring the subsequent filtration effect of the filter plate 9. When the connecting rod 14 disengages from the guide plate 15, the scraper 11 will rise and reset under the elastic action of the spring 13, thus providing a condition for the next scraping operation of the scraper 11.

[0032] Finally, the collection box 10 can be pulled out of the housing 6 and cleaned.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
