Description

Technical Field

[0001] The invention relates to the technical field of machine tool processing equipment, and in particular to a scraping chip removal device for a machine tool. Background Art

[0002] Chip conveyor is a kind of functionally independent accessory. With the development of CNC lathe technology, its stability and degree of automation have been continuously improved, and it is widely used in various types of CNC lathes. When processing parts on machine tools, chip conveyors are usually required to remove chips to ensure the quality of the processed parts. Machine tool chip conveyors are mainly used to collect various metal and non-metal debris produced by the machine and transfer these debris to the collection vehicle.

[0003] The existing scraper-type chip conveyor is prone to have residues on the scraper and at the discharge point when scraping out the broken iron chips. When there are too many broken iron chips remaining on the scraper, the broken iron chips can easily affect the transmission chain inside the chip conveyor, thereby greatly affecting the chip removal efficiency of the chip conveyor. In severe cases, the scraper chip conveyor may even be damaged. At the same time, when too much broken iron chips accumulate at the discharge point, it will also affect the discharge efficiency, and the broken iron chips accumulated at the discharge point can easily be brought into the chip conveyor again by the scraper. Summary of the invention

[0004] In order to overcome the disadvantage that iron chips are easily left on the chip removal scraper and at the discharge point, the purpose of the present invention is to provide a scraping chip removal device for machine tools that can automatically clean the iron chips remaining on the scraper and prevent excessive iron chips from accumulating at the discharge point.

[0005] The technical solution is: a scraping chip removal device for machine tools, including an installation shell, a cover plate, a servo motor, a belt module, a scraper, a cleaning mechanism and a blowing mechanism. A cover plate is installed on the top of the installation shell, and a feed port and a discharge port are respectively provided on the left and right sides of the installation shell. A servo motor is installed on the right front side of the installation shell, and the servo motor is located in the upper right position. A belt module is installed in the installation shell, and the belt module consists of a drive shaft and a transmission belt. The output shaft of the servo motor is connected to the drive shaft at the discharge port through a coupling. Scrapers are evenly arranged on the transmission belt of the belt module. A cleaning mechanism for cleaning the scraper is provided at the discharge port of the installation shell, and a blowing mechanism for blowing away debris is also provided on the top of the installation shell.

[0006] As a further preferred scheme, the cleaning mechanism includes a large gear, a rotating shaft, a small gear, a transmission module, a cleaning brush, a sliding frame and a sliding frame. The large gear is fixedly connected to the output shaft of the servo motor through a coupling. The large gear is located outside the mounting shell. A rotating shaft is rotatably installed in the mounting shell. Both ends of the rotating shaft pass through the outside of the mounting shell. The rotating shaft corresponds to the transmission shaft. A small gear is fixedly connected to the end of the rotating shaft. The small gear meshes with the large gear. A transmission module is installed on the rotating shaft. The transmission module is located inside the mounting shell and corresponds to the transmission shaft. A cleaning brush is installed on the transmission module. A sliding frame is fixedly connected to the edge of the transmission module. A sliding frame is symmetrically fixedly connected to the right edge of the mounting shell. The transmission module is slidably installed in the sliding frame through the sliding frame.

[0007] As a further preferred scheme, the blowing mechanism includes a mounting frame, a micro motor, fan blades and a fan protection net. The mounting frame is fixedly connected to the top of the mounting shell, the mounting frame is located at the discharge port, the micro motor is installed in the mounting frame, the fan blades are fixedly connected to the output shaft of the micro motor, and the fan protection nets are fixedly connected to the top and bottom of the mounting frame.

[0008] As a further preferred scheme, it also includes a pushing mechanism, which includes a connecting frame, a first extrusion block, a second extrusion block and an elastic member. The end of the transmission shaft at the discharge port of the mounting shell is fixedly connected to the connecting frame, the connecting frame is located outside the mounting shell, the first extrusion block is fixedly connected to the bottom of the connecting frame, the second extrusion block is fixedly connected to one end of the rotating shaft, and an elastic member is provided at the other end of the rotating shaft, one end of the elastic member is connected to the end of the rotating shaft, and the other end is connected to the mounting shell, and the second extrusion block corresponds to the first extrusion block.

[0009] As a further preferred embodiment, a splash-proof mechanism is also included, which includes a splash-proof cover, an observation window and a handle. The splash-proof cover is fixedly connected to the right side of the discharge port of the installation shell, the observation window is rotatably connected to the rear edge of the splash-proof cover, and the handle is fixedly connected to the edge of the observation window.

[0010] As a further preferred solution, a guiding mechanism is also included, which includes a mounting frame and a guiding frame. The mounting frame is symmetrically fixed to the right edge of the mounting shell, and the mounting frames on the front and rear sides are commonly fixed to the guiding frame, and the guiding frame corresponds to the cleaning brush.

[0011] As a further preferred scheme, a collecting mechanism is also included, which includes a push-pull guide rail and a push-pull box. The push-pull guide rails are symmetrically fixed on the front and rear sides of the installation shell, and the push-pull guide rails correspond to the discharge port.

[0013] As a further preferred solution, there are at least two micro motors and fan blades.

[0014] As a further preferred solution, the transparent portion of the observation window is made of an acrylic plate.

[0015] Compared with the prior art, the present invention has the following advantages: 1. The present invention is provided with a cleaning mechanism and a blowing mechanism. When the scraper contacts the cleaning brush, the residual iron chips on the scraper will be brushed off by the cleaning brush. The operation of the micro motor on the top of the mounting shell will cause the fan blades to rotate, thereby blowing off the swept iron chips, effectively preventing the swept iron chips from falling into the mounting shell and then affecting the cleaning efficiency, thereby achieving the effect of self-cleaning the residual iron chips on the scraper and preventing the easy accumulation of iron chips at the discharge point.

[0016] 2. The present invention provides a pushing mechanism, and the end of the transmission shaft is fixedly connected to the first extrusion block through a connecting frame. Since the first extrusion block is eccentric to the rotation center of the transmission shaft, it intermittently squeezes the second extrusion block during rotation, so that the cleaning brush can slide back and forth to clean the sticky iron chips remaining on the scraper without manual pushing.

[0017] 3. The present invention provides a guide mechanism so that when the iron chips are swept down by the cleaning brush, they can directly slide to the bottom of the discharge port through the guide frame. Moreover, since the guide frame is in contact with the cleaning brush, when there are small iron chips attached to the surface of the cleaning brush, the guide frame can act as a scraper of the cleaning brush to clean up the small iron chips on the surface of the cleaning brush.

DETAILED DESCRIPTION

[0031] The technical solution is further described below in conjunction with specific embodiments. It should be noted that the words indicating directions such as up, down, left, and right mentioned in this article are only for the position of the structure shown in the corresponding drawings. The serial numbers of the parts in this article, such as first, second, etc., are only used to distinguish the objects described and do not have any order or technical meaning. The words such as connection and coupling in this application include direct and indirect connection (coupling) unless otherwise specified. Example 1

[0032] A scraping chip removal device for a machine tool, such as Figure 1-Figure 7As shown, it includes an installation shell 1, a cover plate 2, a servo motor 3, a belt module 4, a scraper 5, a cleaning mechanism 6 and a blowing mechanism 7. The cover plate 2 is installed on the top of the installation shell 1. The left and right sides of the installation shell 1 are respectively provided with a feed port 13 and a discharge port 14. The servo motor 3 is installed on the front right part of the installation shell 1. The servo motor 3 is located in the upper right position. The belt module 4 is installed in the installation shell 1. The belt module 4 consists of a transmission shaft 41 and a transmission belt 42. The output shaft of the servo motor 3 is connected to the transmission shaft 41 at the discharge port 14 through a coupling. The transmission belt 42 of the belt module 4 is evenly distributed with scrapers 5. The discharge port 14 of the installation shell 1 is provided with a cleaning mechanism 6 for cleaning the scraper 5. The top of the installation shell 1 is also provided with a blowing mechanism 7 for blowing away debris.

[0033] like Figure 1 , Figure 4 and Figure 5 As shown, the cleaning mechanism 6 includes a large gear 601, a rotating shaft 602, a small gear 603, a transmission module 604, a cleaning brush 605, a sliding frame 606 and a sliding frame 607. The large gear 601 is fixedly connected to the output shaft of the servo motor 3 through a coupling. The large gear 601 is located outside the installation shell 1. A rotating shaft 602 is rotatably installed in the installation shell 1. Both ends of the rotating shaft 602 penetrate the outside of the installation shell 1. The rotating shaft 602 corresponds to the transmission shaft 41. The rotating shaft 602 A small gear 603 is fixedly connected to the end, and the small gear 603 is meshed with the large gear 601. A transmission module 604 is installed on the rotating shaft 602. The transmission module 604 is located inside the installation shell 1 and corresponds to the transmission shaft 41. A cleaning brush 605 is installed on the transmission module 604. A sliding frame 606 is fixedly connected to the edge of the transmission module 604. A sliding frame 607 is symmetrically fixedly connected to the right edge of the installation shell 1. The transmission module 604 is slidably installed in the sliding frame 607 through the sliding frame 606.

[0034] like Figure 1 , Figure 6 and Figure 7 As shown, the blowing mechanism 7 includes a mounting frame 701, a micro motor 702, fan blades 703 and a fan protection net 704. The mounting frame 701 is fixedly connected to the top of the mounting shell 1, and the mounting frame 701 is located at the discharge port 14. The micro motor 702 is installed in the mounting frame 701, and the fan blades 703 are fixedly connected to the output shaft of the micro motor 702. The fan protection net 704 is fixedly connected to the top and bottom of the mounting frame 701.

[0035] When using the device, place the device on a machine tool that needs to collect iron chips, then start the servo motor 3 and the micro motor 702. When the iron chips fall from the feed port 13 into the installation shell 1, the servo motor 3 will keep the belt module 4 running. At the same time, since the transmission belt 42 of the belt module 4 is provided with a scraper 5, the scraper 5 will drive the iron chips to move to the discharge port 14 of the installation shell 1. The scraper 5 will keep moving and will come into contact with the cleaning brush 605. When the servo motor 3 is started, the large gear 601 will be driven to rotate, and the small gear 603 meshing with it will also rotate. The rotation of the small gear 603 will then cause the transmission module 604 on the rotating shaft 602 to operate. Since the transmission module 604 is provided with a cleaning brush 605, each scraper 5 will contact the cleaning brush 605. When the brush 605 comes into contact, the residual iron filings on the scraper 5 will be brushed off by the cleaning brush 605. At the same time, when sticky iron filings remain on the scraper 5, such as iron filings attached with lubricating oil, the end of the rotating shaft 602 exposed outside the mounting shell 1 can be pushed, so that the cleaning brush 605 can slide back and forth slightly, thereby cleaning up the sticky iron filings. At the same time, when cleaning the residual iron filings on the scraper 5, the operation of the micro motor 702 on the top of the mounting shell 1 will cause the fan blades 703 to rotate, thereby blowing off the swept iron filings, effectively preventing the swept iron filings from falling into the mounting shell 1, thereby affecting the cleaning efficiency, thereby achieving the effect of being able to self-clean the residual iron filings on the scraper 5 and preventing the iron filings from being easily accumulated at the discharge point. Example 2

[0036] On the basis of Example 1, Figure 1 and Figure 8 As shown, it also includes a pushing mechanism 8, which includes a connecting frame 801, a first extrusion block 802, a second extrusion block 803 and an elastic member 804. The end of the transmission shaft 41 at the discharge port 14 of the mounting shell 1 is fixedly connected to the connecting frame 801, and the connecting frame 801 is located outside the mounting shell 1. The first extrusion block 802 is fixedly connected to the bottom of the connecting frame 801, and the second extrusion block 803 is fixedly connected to one end of the rotating shaft 602. The other end of the rotating shaft 602 is provided with an elastic member 804, and one end of the elastic member 804 is connected to the end of the rotating shaft 602, and the other end is connected to the mounting shell 1. The second extrusion block 803 corresponds to the first extrusion block 802.

[0037] like Figure 1 and Fig. 9 As shown, it also includes a splash-proof mechanism 9, which includes a splash-proof cover 901, an observation window 902 and a handle 903. The splash-proof cover 901 is fixedly connected to the right side of the discharge port 14 of the mounting shell 1, and the observation window 902 is rotatably connected to the rear edge of the splash-proof cover 901, and the handle 903 is fixedly connected to the edge of the observation window 902.

[0038] like Figure 1 and Fig.10 As shown, it also includes a guide mechanism 10, which includes a mounting frame 101 and a guide frame 102. The mounting frame 101 is symmetrically fixed to the front and rear edge of the right side of the mounting shell 1, and the mounting frames 101 on the front and rear sides are commonly fixed to the guide frame 102, and the guide frame 102 corresponds to the cleaning brush 605.

[0039] like Figure 1 and Fig.11 As shown, a collecting mechanism 11 is also included. The collecting mechanism 11 includes a push-pull guide rail 111 and a push-pull box 112. The push-pull guide rails 111 are symmetrically fixed on the front and rear sides of the installation shell 1. The push-pull guide rails 111 correspond to the discharge port 14. The push-pull box 112 is slidably installed in the push-pull guide rails 111 on the front and rear sides. The push-pull box 112 is directly opposite to the bottom of the discharge port 14.

[0040] like Fig.12 As shown, detachable moving wheels 12 are also included, and detachable moving wheels 12 are installed on both left and right sides of the bottom end of the mounting shell 1.

[0041] like Figure 7 As shown, at least two micro motors 702 and fan blades 703 are provided.

[0042] like Fig. 9 As shown, the transparent portion of the observation window 902 is made of an acrylic plate.

[0043] When the servo motor 3 is running, since the end of the transmission shaft 41 is fixedly connected to the first extrusion block 802 through the connecting frame 801, and since the first extrusion block 802 is eccentric to the center of the transmission shaft 41, it will intermittently squeeze the second extrusion block 803 during rotation, and will also squeeze the elastic member 804. Under the action of the elastic member 804, the cleaning brush 605 can slide back and forth to clean the sticky iron chips remaining on the scraper 5 without manual push.

[0044] When the scraper 5 scrapes the broken iron chips toward the discharge port 14, a splash guard 901 is fixedly connected to the discharge port 14, which can effectively prevent the scraper 5 from splashing too far when carrying the broken iron chips out, thereby requiring additional secondary cleaning of the chip removal environment. At the same time, since the splash guard 901 is equipped with an observation window 902, the staff can intuitively see through the observation window 902 whether the internal belt module 4 is operating normally, and at the same time, they can also see the degree of wear of the cleaning brush 605 at the discharge port 14 without removing the splash guard 901. When the cleaning brush 605 needs to be replaced, the observation window 902 can be easily opened by pulling the handle 903 to replace the cleaning brush 605.

[0045] When the cleaning brush 605 is cleaning the iron chips remaining on the scraper 5, since the guide frame 102 is fixedly connected to the discharge port 14, the iron chips can directly slide to the bottom of the discharge port 14 through the guide frame 102 when being swept down by the cleaning brush 605, and since the guide frame 102 is in contact with the cleaning brush 605, when there are fine iron chips attached to the surface of the cleaning brush 605, the guide frame 102 can act as a scraper plate of the cleaning brush 605 to clean up the fine iron chips on the surface of the cleaning brush 605.

[0046] When the iron chips fall to the outside of the installation shell 1, since a push-pull box 112 is installed below the discharge port 14, the iron chips will not fall directly to the ground, but will fall into the push-pull box 112. When too much iron chips accumulate in the push-pull box 112, they can be pulled out for cleaning.

[0047] When the device is moved to other machine tools for use, it can be easily moved to the use site through the detachable moving wheels 12 at the bottom.

[0048] The two micro motors 702 and the fan blades 703 can provide a stronger wind force, effectively preventing excessive accumulation of broken iron filings at the discharge port 14.

[0049] Acrylic sheets do not produce fragments when broken and are safer than glass.

[0050] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
