Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, specifically to a modular CNC machining machine tool bed structure. Background Technology

[0002] CNC machine tools, short for Computer Numerical Control machine tools, are modern processing equipment that integrates mechanical manufacturing technology, computer technology, automatic control technology, sensing and detection technology, and network communication technology. They use computer programs to digitally control the machine tool's motion trajectory and processing parameters, enabling high-precision and high-efficiency processing of various mechanical parts. They are core equipment in intelligent manufacturing systems, completely changing the traditional machining mode that relies on manual operation and promoting the automation and intelligent upgrading of the manufacturing industry.

[0003] Currently, cleaning of most CNC machine tool worktables still relies on manual operation. After machining, operators must manually remove residual metal shavings and coolant from the table surface using tools such as scrapers and brushes. This method is not only inefficient but also fails to achieve a thorough cleaning of the table surface. Residual shavings can easily scratch the workpiece surface during subsequent machining, affecting the surface finish and dimensional accuracy of the machined parts. Furthermore, during manual cleaning, the hard contact between the scraper and the worktable surface or improper control of the operating force can easily damage the table surface, shortening its lifespan. In addition, prolonged contact with coolant can cause health problems such as skin allergies for operators. The work is physically demanding and carries significant risks. Regarding coolant treatment, while traditional machine tools are often equipped with simple collection devices, they generally lack efficient solid-liquid separation and recycling mechanisms. During machining, coolant mixes with shavings and flows freely, contaminating machine tool components and the working environment. This also results in a large amount of coolant being unusable due to impurities, causing serious resource waste and increasing machining costs. Utility Model Content

[0004] The purpose of this invention is to provide a modular CNC machining bed structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular CNC machining bed structure, including a machine tool and a worktable. The worktable is fixed to the top of the machine tool, and a storage slot is fixed to one end of the worktable. A filter assembly is snapped into the inside of the storage slot. Supporting horizontal plates are fixed to both sides of the outer wall of the storage slot. A driving component is fixed to one end face of the supporting horizontal plate. A limiting component is fixed to one side of the top of the driving component. A rotating support rod is rotatably mounted on the top of the driving component. A cleaning scraper is fixed to one side of the top of the rotating support rod. An auxiliary slide rail is fixed inside the supporting horizontal plate on the other side.

[0006] Preferably, a guide pipe is provided on one side of the bottom of the receiving tank, so as to guide the coolant filtered by the filter assembly.

[0007] Preferably, the bottom end of the cleaning scraper is formed with a wedge-shaped rubber pad, which can be driven by the drive component to clean the debris and coolant on the top of the workbench into the inside of the collection tank.

[0008] Preferably, the filter assembly includes a filter screen, the filter screen slides inside the storage groove, a cavity is formed inside the outer frame of the filter screen, a limiting rod slides inside the cavity, a through hole is formed inside one end of the limiting rod, and a driving push rod slides inside the through hole.

[0009] Preferably, a wedge-shaped drive block is fixed on one side of the drive lever, and the limit rod can be moved by driving the drive lever.

[0010] Preferably, a spring is fixed on one side of the limiting rod. The spring is a reset spring, and the other end of the reset spring is fixed to the inner wall of the filter screen outer frame cavity. The elasticity of the reset spring can drive the limiting rod to reset.

[0011] Preferably, the driving component includes a driving motor, the driving motor is fixed to one side of the supporting cross plate, a driving screw is fixed to one end of the output shaft of the driving motor, and a sliding block is threaded on the outer wall of the driving screw.

[0012] Preferably, the bottom end of the sliding block has a through hole, and the through hole is provided with a thread that matches the outer wall of the drive screw, so that the sliding block can be moved by the thread transmission principle.

[0013] Preferably, the limiting component includes a limiting slide rail, one side of the sliding block is fixed with the limiting slide rail, a sliding plate is slidably mounted on the outer wall of the limiting slide rail, and one side of the sliding plate is fixed with a limiting rod.

[0014] Preferably, a through hole is provided on one side of the sliding block, and a limit hole is provided on one side of the rotating support rod, which, together with the limit rod, can limit the rotation support rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are: An automated worktable cleaning mechanism is constructed through the coordinated design of the drive components, rotating support rod, and cleaning scraper. The drive motor drives the drive screw to rotate, which in turn drives the sliding block to move along a preset trajectory using the threaded transmission principle. This, in turn, drives the cleaning scraper to reciprocate on the worktable surface. Combined with the wedge-shaped rubber pad at the bottom of the cleaning scraper, debris and residual coolant on the top of the worktable are thoroughly scraped off and guided to the collection tank. Compared to traditional manual cleaning methods, this significantly improves cleaning efficiency, avoids potential damage to the worktable caused by manual operation, and reduces the labor intensity of operators. The combined design of the collection tank and filter assembly enables immediate recovery and purification of the coolant. The collection tank, as a centralized collection unit for cleaning waste, can quickly receive debris and coolant introduced by the cleaning scraper. The mixture that falls in undergoes solid-liquid separation through a filter screen. The filtered coolant is precisely discharged and recycled through a guide pipe at the bottom of the collection tank, effectively reducing coolant waste, lowering processing costs, and preventing uncontrolled coolant flow from polluting machine tool components and the working environment. The filter assembly adopts a detachable snap-fit ​​structure and features an innovative quick-locking mechanism consisting of a limit rod, a drive rod, and a return spring. When cleaning filter debris, simply press the drive rod downwards. The wedge-shaped block's inclined surface drives the limit rod to compress the return spring and retract, quickly releasing the filter screen from the storage tank. Pulling the filter screen upwards completes the debris cleaning. After cleaning, resetting the filter screen allows the return spring's elasticity to automatically spring back and lock the limit rod. The entire operation requires no tools, enabling quick disassembly and maintenance of the filter screen, significantly improving the equipment's maintenance convenience. The filter screen's solid-liquid separation function effectively intercepts machining debris, preventing it from entering the guide pipe with the coolant and causing blockage. This reduces the risk of failure in the machine tool's hydraulic or cooling systems, extends the service life of related components, and reduces equipment maintenance costs and downtime.

A guide pipe is provided on one side of the bottom of the collection tank 3, so as to guide the coolant filtered by the filter component. A wedge-shaped rubber pad is formed at the bottom of the cleaning scraper 15. Driven by the drive component, the debris and coolant on the top of the workbench 2 can be cleaned into the inside of the collection tank 3.

[0020] The filter assembly includes a filter screen 4, which slides inside the receiving groove 3. The filter screen 4 can separate and filter debris and coolant. A cavity is opened in the outer frame of the filter screen 4, and a limiting rod 5 slides in the cavity. The limiting rod 5 can limit the filter screen 4. A through hole is opened in one end of the limiting rod 5, and a driving rod 6 slides in the through hole. The driving rod 6 drives the limiting rod 5 to move through a wedge block fixed on one side. A wedge driving block is fixed on one side of the driving rod 6. The driving rod 6 can drive the limiting rod 5 to move. A spring is fixed on one side of the limiting rod 5. The spring is a return spring. The other end of the return spring is fixed to the inner wall of the cavity of the outer frame of the filter screen 4. The elasticity of the return spring can drive the limiting rod 5 to return to its original position.

[0021] The driving component includes a drive motor 8, which is fixed to one side of the supporting plate 7. The drive motor 8 can provide power to the drive screw 9. The drive screw 9 is fixed to one end of the output shaft of the drive motor 8. The drive screw 9 can drive the sliding block 10 to move through the drive of the drive screw 8. The outer wall of the drive screw 9 has a threaded sliding block 10. The sliding block 10 drives the rotating support rod 14 to move through the drive of the drive screw 9. A through hole is opened inside the bottom end of the sliding block 10. The through hole is provided with a thread that matches the outer wall of the drive screw 9.

[0023] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0024] After machine tool 1 finishes its work, the workpiece fixture is removed from the top of worktable 2. The slide plate 12 is moved outward, causing the limit rod 13 to move outward and release its restriction on the rotating support rod 14. The rotating support rod 14 is then rotated upward, causing the cleaning scraper 15 to rotate upward to a suitable position. The slide plate 12 is then released, and a spring on one side of the slide plate 12 resets it. The slide plate 12 then resets the limit rod 13, which in turn limits the rotating support rod 14. The drive motor 8 is then connected to an external control unit. The drive motor 8 starts and drives the drive screw 9 to rotate via its output shaft. The rotation of the lead screw 9 drives the sliding block 10 to move left and right through the threaded transmission principle. The sliding block 10 drives the rotating support rod 14 to move left and right. The rotating support rod 14 drives the cleaning scraper 15 to move left and right. The left and right movement of the cleaning scraper 15 cleans the debris and coolant at the top of the worktable 2 into the collection tank 3. The debris and coolant fall into the filter screen 4. The filter screen 4 filters and separates the debris and coolant. After filtration, the drive lever 6 is pressed down. The drive lever 6 moves down and drives the limit rod 5 to move through the wedge block, thereby canceling the limit on the filter screen 4. The filter screen 4 moves up to clean the debris in the filter screen 4.
