Description

Technical Field

[0001] This utility model relates to the field of milling machine processing technology, specifically to a chip cleaning and collection mechanism for gantry milling machines. Background Technology

[0002] CNC gantry grinding machines are machine tools that use grinding wheels to grind the surface of workpieces. Most grinding machines use high-speed rotating grinding wheels for grinding, while a few use other grinding wheels and free abrasives such as oilstones, abrasive belts, honing machines, ultra-precision machining tools, belt grinders, grinding machines, and polishing machines. After mechanical grinding, traditional CNC gantry grinding machines produce a large amount of iron filings on the surface of the grinding machine. Excessive accumulation of iron filings can easily affect the efficiency of the grinding machine. After the grinding is completed, the grinding machine operator needs to manually clean the filings, which is slow and can easily increase the labor intensity of the grinding machine operator.

[0003] Chinese Utility Model Patent Publication No. CN203343830U discloses a bridge-type CNC gantry grinding machine. The specification of this bridge-type CNC gantry grinding machine discloses that it provides a bridge-type CNC gantry grinding machine with two grinding heads. Compared with existing technologies, this utility model bridge-type CNC gantry double-grinding head grinding machine allows workpieces to be continuously processed on multiple surfaces and inclined surfaces in a single clamping operation. It can process the same workpiece or different workpieces simultaneously, improving processing accuracy and efficiency. However, this bridge-type CNC gantry grinding machine does not automatically clean the iron filings on the worktable surface after work. Excessive accumulation of iron filings can easily affect the grinding machine's efficiency. After grinding, manual cleaning by the grinding machine operator is required, which is slow and increases the labor intensity of the grinding machine operator. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a debris cleaning and collection mechanism for gantry milling machines, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: a debris cleaning and collection mechanism for gantry milling machines, including a device base, a worktable, and a milling head mechanism located above the worktable. A second motor is fixedly installed at the end of the device base away from the milling head mechanism. A lead screw is fixedly installed on the output shaft of the second motor. A cleaning frame is threadedly connected to the outer surface of the lead screw. A guide rod is slidably installed at the end of the cleaning frame away from the lead screw. A scraper and a cleaning assembly are fixedly installed at the end of the cleaning frame near the worktable. A waste bin is provided at the end of the device base away from the cleaning assembly. A chip guide plate is fixedly installed at the end of the waste bin near the worktable. A connecting block is fixedly installed at the end of the waste bin near the device base. An installation protrusion is fixedly installed at the end of the connecting block near the device base. A fixing block is fixedly installed at the end of the device base near the waste bin. An installation groove is provided in the center of the end of the fixing block near the waste bin.

[0006] Preferably, a support foot and casters are fixedly installed at the end of the device base away from the worktable, a rack is fixedly installed at the top of the device base away from the worktable, a slide rail fixedly installed on the worktable is provided between the rack and the worktable, a movable seat is slidably installed at the end of the slide rail away from the device base, a motor is fixedly installed on the top side of the movable seat, and a gear is fixedly installed on the output shaft of the motor.

[0007] The above technical solution improves the stability of the device during operation by setting support feet, and the installation of casters facilitates the transfer of the device by staff, eliminating the need for manual handling and reducing the risk of damage during manual handling.

[0008] Preferably, the rack and gear are meshed together, and the slide rails are provided in two identical sets, which are symmetrically distributed on the top of the worktable. Both sets of slide rails are slidably connected to the movable seat.

[0009] Through the above technical solution, by using the design of a rack and pinion meshing together, when the first motor is started, the output shaft of the first motor drives the gear to rotate, thereby causing the displacement of the moving seat. In conjunction with two sets of slide rails, the stability and balance of the moving seat during movement are increased, preventing the moving seat from shifting or shaking during movement.

[0010] Preferably, the cleaning assembly includes a connecting post, a cleaning brush is fixedly installed at the end of the connecting post away from the cleaning frame, and bristles are fixedly installed at the end of the cleaning brush away from the connecting post.

[0011] The above technical solution incorporates a cleaning component that can sweep away residual debris on the workbench, preventing excessive debris accumulation from affecting the normal operation of the device.

[0012] Preferably, the brush bristles are arranged in multiple identical groups, and the multiple groups of brush bristles are distributed at equal intervals at the bottom of the cleaning brush. Two adjacent groups of brush bristles are staggered. The scraper is located on the bottom of the cleaning frame near the milling head mechanism, and the cleaning assembly is located on the bottom of the cleaning frame away from the milling head mechanism.

[0013] The above technical solution expands the contact area between the cleaning brush and the workbench by setting multiple sets of staggered bristles, which can more effectively clean debris of different locations and sizes, avoiding debris loss. The scraper and cleaning component are located at different positions on the bottom of the cleaning frame. The scraper can first scrape up larger debris, and then the cleaning component can clean up the debris that has fallen into the workbench. The debris generated during processing is pushed into the waste bin. The cooperation between the scraper and the cleaning component improves the cleaning efficiency.

[0014] Preferably, the cross-section of the chip guide plate is triangular, and the width of the chip guide plate is greater than the width of the worktable.

[0015] The above technical solution, by setting the cross-section of the chip guide plate to a "triangular" structure, facilitates the rapid and accurate falling of debris into the waste bin along the inclined surface of the chip guide plate, realizing automatic debris collection and reducing manual intervention. By making the width of the chip guide plate greater than the width of the workbench, it can effectively prevent debris from scattering from the edge of the workbench, ensuring that all cleaned debris can smoothly enter the waste bin along the chip guide plate, reducing the need for secondary manual cleaning and improving cleaning efficiency.

[0016] Preferably, the mounting protrusion and the mounting groove are mating components, the mounting protrusion and the mounting groove are slidably connected, and the diameter of the mounting protrusion is greater than the width of the mounting groove.

[0017] The above technical solution, through the sliding connection between the mounting protrusion and the mounting groove, achieves a detachable design for the waste bin, which facilitates centralized processing of collected debris by staff. After cleaning, it can be easily reinstalled, improving cleaning efficiency. By setting the diameter of the mounting protrusion to be larger than the width of the mounting groove, it is ensured that the waste bin will not easily fall off after installation, thereby improving the stability and reliability of the waste bin in the process of collecting debris.

[0018] Compared with the prior art, this utility model provides a debris cleaning and collection mechanism for gantry milling machines, which has the following beneficial effects:

[0019] 1. This gantry milling machine's chip cleaning and collection mechanism, through the scraper and cleaning component at different positions on the bottom of the cleaning frame, can first scrape up larger chips with the scraper, and then sweep up the chips that have fallen into the worktable with the cleaning component, pushing the chips generated during processing into the waste bin. By setting multiple sets of staggered bristles, the contact area between the cleaning brush and the worktable surface is increased, which can more effectively clean chips of different positions and sizes, avoid chip leakage, and improve cleaning efficiency through the cooperation of the scraper and cleaning component.

[0020] 2. In this gantry milling machine's debris collection and cleaning mechanism, during the cleaning process, the debris swept by the scraper and cleaning components moves towards the waste bin. By setting the cross-section of the chip guide plate to a "triangular" structure, the debris can fall quickly and accurately into the waste bin along the inclined surface of the chip guide plate, realizing automatic debris collection and reducing manual intervention. The design of the mounting protrusion and the mounting groove being slidably connected enables the waste bin to be detached, facilitating centralized handling of collected debris by staff. After cleaning, it can be easily reinstalled, improving cleaning efficiency. By setting the diameter of the mounting protrusion to be larger than the width of the mounting groove, it is ensured that the waste bin will not easily fall off after installation, thereby improving the stability and reliability of the waste bin in the debris collection process.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1: As Figure 1-8 As shown, the present invention provides a debris cleaning and collection mechanism for a gantry milling machine, including a device base 1, a worktable 2, and a milling head mechanism 10 located above the worktable 2. A motor 11 is fixedly installed at the end of the device base 1 away from the milling head mechanism 10. A lead screw 12 is fixedly installed on the output shaft of the motor 11. A cleaning frame 14 is threadedly connected to the outer surface of the lead screw 12. A guide rod 13 is slidably installed at the end of the cleaning frame 14 away from the lead screw 12. A scraper 15 and a cleaning assembly 16 are fixedly installed at the end of the cleaning frame 14 near the worktable 2. A waste bin 17 is provided at the end of the device base 1 away from the cleaning assembly 16. A chip guide plate 18 is fixedly installed at the end of the waste bin 17 near the worktable 2. A connecting block 19 is fixedly installed at the end of the waste bin 17 near the device base 1. An installation protrusion 20 is fixedly installed at the end of the connecting block 19 near the device base 1. A fixing block 21 is fixedly installed at the end of the device base 1 near the waste bin 17. An installation groove 22 is provided in the center of the end of the fixing block 21 near the waste bin 17.

[0032] Specifically, a support leg 3 and casters 4 are fixedly installed at the end of the device base 1 away from the worktable 2. A rack 5 is fixedly installed at the top end of the device base 1 away from the worktable 2. A slide rail 7, fixedly installed on the worktable 2, is provided between the rack 5 and the worktable 2. A movable seat 6 is slidably installed at the end of the slide rail 7 away from the device base 1. A motor 8 is fixedly installed on the top side of the movable seat 6, and a gear 9 is fixedly installed on the output shaft of the motor 8. The advantages are that the support leg 3 improves the stability of the device during operation, and the casters 4 facilitate the transportation of the device by workers, eliminating the need for manual handling and reducing the risk of damage to the device during manual handling.

[0033] Specifically, the rack 5 and gear 9 are meshed together, and two identical sets of slide rails 7 are provided. The two sets of slide rails 7 are symmetrically distributed on the top of the worktable 2, and both sets of slide rails 7 are slidably connected to the movable seat 6. The advantage is that, through the meshing design of the rack 5 and gear 9, when the motor 8 is started, the output shaft of the motor 8 drives the gear 9 to rotate, thereby causing the movable seat 6 to move. Combined with the two sets of slide rails 7, this increases the stability and balance of the movable seat 6 during movement, preventing the movable seat 6 from shifting or shaking during movement.

[0034] Specifically, the cleaning assembly 16 includes a connecting post 1601, with a cleaning brush 1602 fixedly installed at the end of the connecting post 1601 away from the cleaning frame 14, and brush bristles 1603 fixedly installed at the end of the cleaning brush 1602 away from the connecting post 1601. The advantage is that the cleaning assembly 16 can clean residual debris on the workbench 2, preventing excessive debris accumulation from affecting the normal operation of the device.

[0035] Example 2: Figure 2-8 As shown, as an improvement over the previous embodiment, the debris cleaning efficiency is improved. Specifically, multiple sets of bristles 1603 are arranged, with the multiple sets of bristles 1603 evenly distributed at the bottom of the cleaning brush 1602, and two adjacent sets of bristles 1603 staggered. The scraper 15 is located on the bottom of the cleaning frame 14 near the milling head mechanism 10, and the cleaning component 16 is located on the bottom of the cleaning frame 14 away from the milling head mechanism 10. The advantage is that by setting multiple sets of staggered bristles 1603, the contact area between the cleaning brush 1602 and the worktable 2 surface is expanded, which can more effectively clean debris of different positions and sizes, avoid debris leakage, and by using the scraper 15 and the cleaning component 16 at different positions on the bottom of the cleaning frame 14, larger debris can be scraped up by the scraper 15 first, and then debris that has fallen into the worktable 2 can be cleaned by the cleaning component 16, pushing the debris generated during processing into the waste bin 17. The cooperation between the scraper 15 and the cleaning component 16 improves the cleaning efficiency.

[0036] Specifically, the chip guide plate 18 has a triangular cross-section, and its width is greater than that of the worktable 2. The advantage is that by setting the chip guide plate 18 to a triangular cross-section, debris can fall quickly and accurately into the waste bin 17 along the inclined surface of the chip guide plate 18, achieving automatic debris collection and reducing manual intervention. Furthermore, the width of the chip guide plate 18, being greater than that of the worktable 2, effectively prevents debris from scattering from the edges of the worktable 2, ensuring that all cleaned debris can smoothly enter the waste bin 17 along the chip guide plate 18, reducing the need for secondary manual cleaning and improving cleaning efficiency.

[0037] Specifically, the mounting protrusion 20 and the mounting groove 22 are mating components, and the mounting protrusion 20 and the mounting groove 22 are slidably connected. The diameter of the mounting protrusion 20 is larger than the width of the mounting groove 22. The advantage is that the slidable connection between the mounting protrusion 20 and the mounting groove 22 enables the detachable design of the waste bin 17, facilitating centralized processing of collected debris by workers. After cleaning, it can be easily reinstalled, improving cleaning efficiency. By setting the diameter of the mounting protrusion 20 to be larger than the width of the mounting groove 22, it ensures that the waste bin 17 will not easily detach after installation, thereby improving the stability and reliability of the waste bin 17 during debris collection.

[0038] Working Principle: During operation, motor 8 is started, and its output shaft drives gear 9 to rotate, thus displacing the moving seat 6. Combined with two sets of slide rails 7, this increases the stability and balance of the moving seat 6 during movement, preventing it from shifting or wobbling. This improves the flexibility of the milling head mechanism 10 during processing. After the milling head mechanism 10 completes processing, motor 11 is started, and its output shaft drives the lead screw 12 to rotate. The cleaning frame 14, connected to the lead screw 12 via a threaded connection, moves linearly under the guidance of the guide rod 13. The scraper 15 and cleaning assembly 16 are positioned at different locations on the bottom of the cleaning frame 14. Larger debris is first scraped up by the scraper 15, and then debris that has fallen into the worktable 2 is swept away by the cleaning assembly 16. The debris generated during processing is pushed into the waste bin 17. Multiple sets of staggered brush bristles 1603 expand the interaction between the cleaning brush 1602 and the worktable. The increased contact area of ​​the two surfaces of the worktable allows for more effective cleaning of debris of different locations and sizes, preventing any loss. The cooperation between the scraper 15 and the cleaning component 16 improves cleaning efficiency. During the cleaning process, the debris swept by the scraper 15 and the cleaning component 16 moves towards the waste bin 17. The triangular cross-section of the chip guide plate 18 facilitates the rapid and accurate falling of debris into the waste bin 17 along its inclined surface, achieving automatic debris collection and reducing manual intervention. The sliding connection between the mounting protrusion 20 and the mounting groove 22 enables the detachable design of the waste bin 17, facilitating centralized processing of collected debris and easy reinstallation after cleaning, thus improving cleaning efficiency. By setting the diameter of the mounting protrusion 20 to be larger than the width of the mounting groove 22, the waste bin 17 is ensured not to easily fall off after installation, thereby improving the stability and reliability of the waste bin 17 during debris collection.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
