Description

Technical Field

[0001] This invention relates to the field of machine tool cleaning technology, specifically to a cross-track double-beam gantry machining center. Background Technology

[0002] A gantry machining center is a machining center whose spindle Z-axis is perpendicular to the worktable. Its overall structure is a large machining center with a portal frame formed by two columns and a top beam, with a crossbeam in the middle of the two columns. It is particularly suitable for machining large and complex-shaped workpieces.

[0003] Gantry machining centers come in various types, including fixed beam, moving beam, moving column, and overhead crane types, as well as composite types. Their machining characteristics, capabilities, and intended applications also differ.

[0004] The worktable of a gantry machining center is basically rectangular. Large castings such as the worktable, bed, column, crossbeam, and slide are made of cast iron or welded parts. The internal cavity of the castings has a honeycomb composite arrangement structure, which is an advanced design. All castings undergo aging and secondary tempering treatment to eliminate residual internal stress, stabilize the material, and ensure the stability of workpiece machining accuracy and machine tool life.

[0005] After processing the workpiece, a large amount of raw material residue will adhere to the machine tool. At this time, the surface of the machine tool needs to be cleaned. In the traditional cleaning process, the waste will be flushed out of the machine tool with the water. The flowing liquid containing waste and water will be directly discharged into the drain pipe through the drainage trough installed in the dustproof box. Since the waste can be melted and reused later, this waste not only easily clogs the drain pipe, but also causes a certain amount of material waste. Therefore, it is necessary to provide a cross-rail double beam gantry machining center to solve the above problems. Summary of the Invention

[0006] Based on this, it is necessary to provide a cross-track double-beam gantry machining center to address the existing technical problems.

[0007] To solve the problems of existing technologies, the technical solution adopted by the present invention is as follows: a cross-track double-beam gantry machining center, including a dustproof box and a machine tool disposed within the dustproof box, and further including a base, a flared waste trough, a waste compression mechanism, a water filter plate, and a waste embedding prevention mechanism. The base is disposed within the dustproof box, and a receiving cavity is formed downward from its top. The flared waste trough is disposed in the upper half of the receiving cavity, with the upper end of the flared waste trough forming a flared chamber, and the lower end of the flared waste trough gradually narrowing into a cylindrical tube. The machine tool is mounted directly above the flared chamber. During cleaning, waste falls into the flared waste trough from all sides of the machine tool along with water. The water filter plate is fixedly disposed within the lower end of the cylindrical tube, and the water filter plate has several sieve holes for supplying water to be discharged outside the cylindrical tube. The waste compression mechanism includes a waste compression disc and a dual-axis displacement mechanism, with the dual-axis displacement mechanism disposed within the flared chamber. Inside, the outer periphery of the dual-axis displacement mechanism is equipped with a semi-circular protective cover connected to the flared chamber and facing downwards. The dual-axis displacement mechanism has a lifting end and a horizontal displacement end. The lifting end of the dual-axis displacement mechanism first drives the waste compression disc downwards into the columnar tube and compresses the waste into a cake shape. Then, it drives the cake-shaped waste to rise. Finally, the horizontal displacement end of the dual-axis displacement mechanism drives the waste compression disc and the cake-shaped waste out of the flared chamber. The waste embedding prevention mechanism is located in the lower half of the receiving cavity. The waste embedding prevention mechanism includes an upper top plate and a transmission assembly. The upper top plate is located directly below the filter screen plate. The top of the upper top plate is equipped with several pins that correspond one-to-one with the screen holes. The transmission assembly is used to drive the upper top plate to rise when the waste compression disc descends, so that each pin blocks the corresponding screen hole upwards, thereby preventing the waste from embedding into several screen holes when it is compressed.

[0008] Furthermore, the transmission assembly includes a first piston, a first cylindrical sleeve, a first spring, and two sets of gear linkage mechanisms. The first cylindrical sleeve is coaxially fixed at the bottom of the filter screen plate. The lower end of the first cylindrical sleeve is open, and a cover plate is fixedly installed on the opening at the lower end of the first cylindrical sleeve. The cap of the first piston is slidably disposed inside the upper half of the first cylindrical sleeve, and the rod of the first piston protrudes outside the filter screen plate. The first spring is vertically disposed inside the first cylindrical sleeve, and its upper and lower ends respectively abut against the lower end of the first piston and the cover plate. Two support blocks are formed on the outer wall of the cap of the first piston, evenly distributed along the circumference of the first piston. Each support block protrudes horizontally through the first cylindrical sleeve. Two openings are provided on the outer wall of the first cylindrical sleeve for the two support blocks to pass through. The vertical groove slides up and down, and the upper top plate is coaxially and movably sleeved on the outer wall of the first columnar sleeve. Two sets of gear linkage mechanisms are respectively located on the sides of the two support blocks. Each set of gear linkage mechanisms includes a frame, a transmission gear, a slider, an elastic pin, and two racks. The frame is fixedly located on the side of the corresponding first columnar sleeve. The transmission gear is rotatably mounted on the frame, and the axis of the transmission gear is horizontal. The slider is slidably connected to the frame, so that the slider can be raised and lowered. Each gear is vertical and meshes with the transmission gear. The two racks are centrally symmetrical about the transmission gear, and the two gears are fixedly connected to the support block and the slider, respectively. The upper and lower ends of the elastic pin are fixedly connected to the bottom of the upper top plate and the top of the slider, respectively, and the lower end of the elastic pin is an elastic telescopic end that can be elastically pressed upward.

[0009] Furthermore, each elastic top pin includes a second piston, a second cylindrical sleeve, and a second spring. The second cylindrical sleeve is vertical, with an open upper end that is fixedly connected to the bottom of the upper top plate. The lower end of the second cylindrical sleeve is coaxially formed with an annular baffle. The cap of the second piston slides inside the second cylindrical sleeve, and the rod of the second piston passes downward through the center of the annular baffle and is fixedly connected to the top of the corresponding slider. The second spring is vertically installed inside the second cylindrical sleeve, with its upper and lower ends abutting against the bottom of the upper top plate and the cap of the second piston, respectively. The second piston is the elastic extension end of the aforementioned elastic top pin.

[0010] Furthermore, the circular part at the top of the upper plate bulges upward, making the top surface of the upper plate umbrella-shaped, and the bottom of the filter screen plate has an umbrella-shaped groove that fits into the top surface of the upper plate.

[0011] Furthermore, the bottom of the receiving cavity is formed with an annular water groove surrounding the outer perimeter of the upper plate, and a drainage groove connected to the annular water groove is provided in the base for draining water to the outside of the base. The annular water groove forms a circular boss in the part of the receiving cavity corresponding to the upper plate, and each stand is fixedly mounted on the circular boss.

[0012] Furthermore, two semi-cylindrical shells that can meet each other are fixed on the circular boss, and the two semi-cylindrical shells meet each other to form a waterproof enclosure that covers the transmission component.

[0013] Furthermore, the semi-circular cover is strip-shaped, and an arched through-slot is provided on one side of the flared compartment. The semi-circular cover is horizontal, and one end of it extends horizontally out of the flared compartment through the arched through-slot. The dual-axis displacement mechanism includes a lead screw slide and a hydraulic cylinder. The lead screw slide is horizontally fixed on the inner wall of the top of the semi-circular cover, and the hydraulic cylinder is vertically fixed on the output end of the lead screw slide. The top of the waste material compression disc is coaxially fixed to the output end of the hydraulic cylinder. The base is provided with a discharge notch for the waste material compression disc and the cake-shaped waste material to be removed from the arched through-slot. The lead screw slide is the horizontal displacement end of the dual-axis displacement mechanism, and the hydraulic cylinder is the lifting end of the dual-axis displacement mechanism.

[0014] Furthermore, the bottom of the waste compression disc is formed with several pins evenly distributed along the circumference of the waste compression disc. The lower end of each pin is tapered into a sharp point, and the outer wall of each pin is formed with several barbs evenly distributed along the circumference of the pin.

[0015] Furthermore, a horizontal support plate is provided above the base. Both ends of the support plate are connected to the base through several horizontal support rods. The bottom of the support plate is connected to the flared waste trough through four support columns arranged in a matrix. The machine tool is fixedly mounted on the top of the support plate.

[0016] Furthermore, an inlet / outlet groove communicating with the receiving cavity is provided on one side of the base, and a cover plate is provided on the inlet / outlet groove.

[0017] The beneficial effects of this invention compared to the prior art are:

[0018] Firstly, this device can collect the waste and water that are flushed out of the machine tool, and can separate the waste and water into solid and liquid components. At the same time, the separated waste can be compressed into a cake shape by the waste compression mechanism, which facilitates the subsequent melting and reuse of the waste.

[0019] Secondly, through the waste embedding mechanism in this device, each screen hole on the filter screen is blocked by a pin before the waste is compressed, thereby preventing the waste from embedding into several screen holes during compression.

[0020] Third, the upward stroke of the upper plate is less than the downward stroke of the waste compression plate. This ensures that each screen hole is blocked before the waste is compressed. So when the upper plate moves upward and is completely in contact with the bottom of the filter screen, that is, when each pin is fully inserted into the corresponding screen hole, the waste compression plate still needs to continue to move downward. At this time, the elastic extension end of each elastic pin provides the waste compression plate with a stroke capacity. So when the upper plate is completely in contact with the bottom of the filter screen, the waste compression plate can continue to descend and compress the waste. Attached Figure Description

[0032] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0033] refer to Figures 1 to 10The illustrated cross-track double-beam gantry milling machine 1 includes a dustproof box and a machine tool 1 housed within the dustproof box. It also includes a base 2, a flared waste trough 3, a waste compression mechanism, a water filter plate 44, and a waste embedding prevention mechanism. The base 2 is located within the dustproof box, and a receiving cavity 4 is formed downwards from its top. The flared waste trough 3 is located in the upper half of the receiving cavity 4. The upper end of the flared waste trough 3 is a flared chamber 5, and the lower end of the flared waste trough 3 gradually narrows into a columnar tube 6. The machine tool 1 is mounted directly above the flared chamber 5. During cleaning, waste material falls into the flared waste trough 3 from all sides of the machine tool 1 along with water. The water filter plate 44 is fixedly installed inside the lower end of the columnar tube 6, and has several sieve holes 7 for supplying water to be discharged outside the columnar tube 6. The waste compression mechanism includes a waste compression disc 8 and a dual-axis displacement mechanism. The dual-axis displacement mechanism is located inside the flared chamber 5. The outer periphery is provided with a semi-circular protective cover 9 connected to the flared chamber 5 and with the opening facing downwards. The dual-axis displacement mechanism has a lifting end and a horizontal displacement end. The lifting end of the dual-axis displacement mechanism first drives the waste compression disc 8 downwards into the columnar tube 6 and compresses the waste into a cake shape. Then, it drives the cake-shaped waste to rise. Finally, the horizontal displacement end of the dual-axis displacement mechanism drives the waste compression disc 8 and the cake-shaped waste to move out of the flared chamber 5. The waste embedding prevention mechanism is located in the lower half of the receiving cavity 4. The waste embedding prevention mechanism includes an upper top plate 10 and a transmission assembly. The upper top plate 10 is located directly below the filter screen plate 44. The top of the upper top plate 10 is provided with several pins 11 that correspond one-to-one with the screen holes 7. The transmission assembly is used to drive the upper top plate 10 to rise when the waste compression disc 8 descends, so that each pin 11 blocks the corresponding screen hole 7 upwards, thereby preventing the waste from embedding into several screen holes 7 when it is compressed.

[0034] After the workpiece is processed, a large amount of raw material residue will be attached to the machine tool 1. At this time, the surface of the machine tool 1 needs to be cleaned. In the traditional cleaning process, the waste will be flushed out of the machine tool 1 along with the water. The flowing liquid containing the waste and water will be directly discharged into the drain pipe (not shown in the figure). Since the waste can be reused by melting later, the waste not only easily clogs the drain pipe, but also causes a certain amount of material waste.

[0035] This device can collect the waste and water that are flushed out of the machine tool 1, and can separate the waste and water into solid and liquid components. After separation, the waste can be compressed into a cake shape by the waste compression mechanism, which facilitates the subsequent melting of the waste. The dust box is existing technology and is not shown in the figure.

[0036] The cleaning process for machine tool 1 when using this device is as follows:

[0037] Before cleaning, the workpieces and workpiece fixtures on the machine tool 1 need to be removed. Then, the surface of the machine tool 1 is rinsed with high-pressure water. The waste material will fall into the flared waste tank 3 from all sides of the machine tool 1 along with the water. During this process, the flowing liquid containing waste material and water will flow down into the columnar tube 6 along the flared chamber 5. After that, the water in the flowing liquid will be discharged through several sieve holes 7 on the filter screen plate 44, while the waste material will be temporarily stored in the columnar tube 6.

[0038] The lifting end of the dual-axis displacement mechanism drives the waste compression disc 8 to descend into the columnar tube 6, and the waste in the columnar tube 6 is compressed into a cake shape by the waste compression disc 8. At the same time, the upper plate 10 rises through the transmission component, and each pin 11 is inserted into the corresponding screen hole 7, so that each screen hole 7 is blocked, thereby preventing the waste from being embedded in several screen holes 7 when being compressed.

[0039] When the waste compression disc 8 rises again through the lifting end of the dual-axis displacement mechanism, the waste compression disc 8 will also move the cake-shaped waste upwards. After that, the waste compression disc 8 and the cake-shaped waste will be moved out of the flared chamber 5 through the horizontal displacement end of the dual-axis displacement mechanism. Finally, the operator can remove the cake-shaped waste attached to the waste compression disc 8 for melting.

[0040] The semi-circular cover 9 is used to prevent waste and water falling from the flared chamber 5 from splashing onto the dual-axis displacement mechanism. The special shape of the semi-circular cover 9 allows waste to flow down the outer wall of the semi-circular cover 9 with the water into the columnar tube 6, thereby preventing waste from adhering to the outer wall of the semi-circular cover 9.

[0041] Since machine tool 1 is mostly rectangular, the base 2 and the flared waste trough 3 need to be machined into rectangles during processing so that they can fit the shape of machine tool 1. During the washing process of machine tool 1, in order to prevent water and waste from splashing out of the flared waste trough 3, a removable baffle (not shown in the figure) can be added around the base 2. The baffle blocks the splashed waste and water, ensuring that the waste and water from machine tool 1 can only enter the flared waste trough 3.

[0042] To demonstrate the specific structure of the transmission assembly, the following features were specifically designed:

[0043] The transmission assembly includes a first piston 12, a first cylindrical sleeve 13, a first spring 14, and two sets of gear linkage mechanisms. The first cylindrical sleeve 13 is coaxially fixed to the bottom of the filter screen plate 44. The lower end of the first cylindrical sleeve 13 is open, and a cover plate 15 is fixedly installed on the opening at the lower end of the first cylindrical sleeve 13. The cap end of the first piston 12 is slidably disposed inside the upper half of the first cylindrical sleeve 13, and the rod end of the first piston 12 protrudes outside the filter screen plate 44. The first spring 14 is vertically disposed inside the first cylindrical sleeve 13, and the upper and lower ends of the first spring 14 abut against the lower end of the first piston 12 and the cover plate 15, respectively. Two support blocks 16 are formed on the outer wall of the cap end of the first piston 12, evenly distributed along the circumference of the first piston 12. Each support block 16 protrudes horizontally from the first cylindrical sleeve 13. Two openings are provided on the outer wall of the first cylindrical sleeve 13 for the two support blocks 16 to slide up and down. The vertical groove 17 and the upper top plate 10 are coaxially and movably sleeved on the outer wall of the first columnar sleeve 13. Two sets of gear linkage mechanisms are respectively set on the sides of the two support blocks 16. Each set of gear linkage mechanisms includes a frame 18, a transmission gear 19, a slider 20, an elastic top pin 21, and two racks 22. The frame 18 is fixedly set on the side of the corresponding first columnar sleeve 13. The transmission gear 19 is rotatably set on the frame 18, and the axis of the transmission gear 19 is horizontal. The slider 20 is slidably connected to the frame 18, so that the slider 20 can be raised and lowered. Each gear is vertical and meshes with the transmission gear 19. The two racks 22 are centrally symmetrical about the transmission gear 19, and the two gears are fixedly connected to the support block 16 and the slider 20 respectively. The upper and lower ends of the elastic top pin 21 are fixedly connected to the bottom of the upper top plate 10 and the top of the slider 20 respectively, and the lower end of the elastic top pin 21 is an elastic telescopic end that can be elastically pressed upward.

[0044] In the initial state, spring 14 is fully released, and the spring force of spring 14 drives piston 12 to move upward. Eventually, the rod of piston 12 will pass through the filter screen plate 44. When the waste compression disc 8 presses down, it will abut against the rod of piston 12, thereby driving piston 12 to move downward. During this process, the cap of piston 12 compresses spring 14, causing spring 14 to generate elastic force. As piston 12 descends, the two supports 16 will drive the two teeth respectively. As rack 22 descends, each rack 22 connected to support block 16 drives the corresponding transmission gear 19 to rotate. The rotation of each transmission gear 19 drives the rack 22 connected to slider 20 to rise. The rising rack 22 drives the upper top plate 10 to rise through the corresponding elastic top pin 21. In this way, through the transmission assembly, when the waste compression plate 8 descends, the upper top plate 10 can be lifted, so that each pin 11 is inserted upward into the corresponding screen hole 7 to prevent the waste from being embedded in several screen holes 7 during compression.

[0045] The upward stroke of the upper plate 10 is less than the downward stroke of the waste compression plate 8, thus ensuring that each screen hole 7 is blocked before the waste is compressed. Therefore, after the upper plate 10 moves upward to fully fit the bottom of the filter screen plate 44, that is, after each pin 11 is fully inserted into the corresponding screen hole 7, the waste compression plate 8 still needs to continue to move downward. At this time, the elastic extension end of each elastic pin 21 provides the waste compression plate 8 with a stroke capacity. When the waste compression plate 8 continues to descend, the slider 20 will continue to drive the elastic pin 21 to rise. At this time, the elastic extension end of the elastic pin 21 will gradually retract upward. Thus, after the upper plate 10 is fully fitted upward to the bottom of the filter screen plate 44, the waste compression plate 8 can continue to descend and compress the waste.

[0046] After the waste material is compressed, the waste material compression disc 8 will move upward along with the compressed waste material into a cake shape. During this process, the first piston 12 gradually loses the resistance of the waste material compression disc 8, and thus the first piston 12 is driven to move upward by the elastic force of the first spring 14. At the same time, through the reversing function of the drive gear, the slider 20 will drive the elastic top pin 21 to descend, and finally the two elastic top pins 21 will drive the upper top plate 10 downward to separate from the filter screen plate 44.

[0047] To demonstrate the specific structure of each elastic top pin 21, the following features are set:

[0048] Each elastic top pin 21 includes a second piston 23, a second cylindrical sleeve 24, and a second spring 25. The second cylindrical sleeve 24 is vertical, with an open structure at its upper end, and is fixedly connected to the bottom of the upper top plate 10. The lower end of the second cylindrical sleeve 24 is coaxially formed with an annular baffle 26. The cap end of the second piston 23 slides inside the second cylindrical sleeve 24, and the rod end of the second piston 23 passes downward through the center of the annular baffle 26 and is fixedly connected to the top of the corresponding slider 20. The second spring 25 is vertically installed inside the second cylindrical sleeve 24, and its upper and lower ends abut against the bottom of the upper top plate 10 and the cap end of the second piston 23, respectively. The second piston 23 is the elastic extension end of the elastic top pin 21.

[0049] Each second spring 25 has a large spring constant, so when the slider 20 moves upward, each second piston 23 will compress the second spring 25 upward and drive the upper plate 10 to move upward. During the movement of the upper plate 10, the second spring 25 is not compressed to its limit, that is to say, the second spring 25 still has a certain deformation. When the upper plate 10 is completely in contact with the bottom of the filter screen plate 44, the waste compression plate 8 continues to descend. At this time, the second piston 23 will compress the second spring 25 upward. The remaining deformation of the second spring 25 gives the waste compression plate 8 a wide stroke capacity to continue to descend.

[0050] The upper plate 10 is made of a thin plate of lightweight material, which makes it easy to be lifted by the second piston 23. During the process of the first piston 12 resetting upward, the slider 20 will drive the second piston 23 to move downward, so that the compressed second spring 25 will gradually release its elasticity. When the cap of the second piston 23 moves downward inside the second columnar sleeve 24 to the annular baffle 26, the cap of the second piston 23 will drive the second columnar sleeve 24 to move downward by touching the annular baffle 26. In this way, the upper plate 10 will be driven downward to separate from the filter screen plate 44.

[0051] Since the upper plate 10 is located directly below the filter screen 44, the water leaking from the filter screen 44 will splash onto the top of the upper plate 10. In order to allow the water on the top of the upper plate 10 to flow down quickly, the following features are specifically designed:

[0052] The circular part at the top of the upper plate 10 bulges upward, so that the top surface of the upper plate 10 is umbrella-shaped, and the bottom of the filter screen plate 44 is provided with an umbrella-shaped groove 27 that fits into the top surface of the upper plate 10.

[0053] When water leaks out from the sieve holes 7 on the filter screen plate 44, it will spray onto the top of the upper plate 10. At this time, the water hanging on the top of the upper plate 10 can quickly flow out in all directions through the umbrella-shaped top surface of the upper plate 10, thereby blocking the water from the transmission components located below the upper plate 10.

[0054] Since the upper top plate 10 is coaxially and movably sleeved on the outer wall of the first columnar sleeve 13, in order to prevent water from flowing through the gap between the upper top plate 10 and the first columnar sleeve 13 and hanging on the outer wall of the first columnar sleeve 13, when several sieve holes 7 are opened on the filter screen plate 44, the sieve holes 7 are as far away from the center of the filter screen plate 44 as possible, so that the water passing through the filter screen plate 44 will flow towards the outer edge of the upper top plate 10 and will not flow into the gap between the upper top plate 10 and the first columnar sleeve 13.

[0055] To drain water flowing down from the top of the upper plate 10 and prevent water from accumulating in the receiving cavity 4, the following features are specifically provided:

[0056] The bottom of the receiving cavity 4 is formed with an annular water trough 28 surrounding the outer perimeter of the upper plate 10. The base 2 has a drainage trough 29 connected to the annular water trough 28 and used to drain water to the outside of the base 2. The annular water trough 28 forms a circular boss 30 in the part of the receiving cavity 4 corresponding to the upper plate 10. Each stand 18 is fixed on the circular boss 30.

[0057] Water flowing down from the top plate 10 will flow into the annular water tank 28. One end of the drain trough 29 can be connected to the drain pipe that is pre-installed in the dustproof box. Then, the water in the annular water tank 28 will flow out through the drain trough 29 to the outside of the base 2 and then directly into the drain pipe.

[0058] To prevent water from splashing onto the transmission components as it falls into the annular water tank 28, the following features are specifically provided:

[0059] Two semi-cylindrical shells 31 that can be joined together are fixed on the circular boss 30. After the two semi-cylindrical shells 31 are joined together, they form a waterproof enclosure 32 that covers the transmission component.

[0060] Water is prevented from splashing onto the transmission components as water falls into the annular water tank 28 by a waterproof barrier 32.

[0061] The outer diameter of the top plate 10 is larger than the outer diameter of the waterproof enclosure 32. After the top plate 10 is completely separated from the filter screen 44, it will cover the opening at the top of the waterproof enclosure 32. In this way, the water flowing down from the top plate 10 will fall from all sides of the waterproof enclosure 32, preventing water from flowing into the transmission components.

[0062] To demonstrate the specific structure of the biaxial displacement mechanism, the following features were specifically designed:

[0063] The semi-circular cover 9 is strip-shaped, and an arched through groove 33 is provided on one side of the flared chamber 5. The semi-circular cover 9 is horizontal, and one end of it extends horizontally out of the flared chamber 5 through the arched through groove 33. The dual-axis displacement mechanism includes a lead screw slide 34 and a hydraulic cylinder 35. The lead screw slide 34 is horizontally fixed on the inner wall of the top of the semi-circular cover 9, and the hydraulic cylinder 35 is vertically fixed on the output end of the lead screw slide 34. The top of the waste material compression disc 8 is coaxially fixed to the output end of the hydraulic cylinder 35. The base 2 has a discharge notch 36 for the waste material compression disc 8 and the cake-shaped waste material to be removed from the part opposite to the arched through groove 33. The lead screw slide 34 is the horizontal displacement end of the dual-axis displacement mechanism, and the hydraulic cylinder 35 is the lifting end of the dual-axis displacement mechanism.

[0064] The waste compression disc 8 is driven to rise and fall by the hydraulic cylinder 35. When the waste compression disc 8 falls, it compresses the waste in the cylindrical tube. When the waste compression disc 8 rises, it will drive the cake-shaped waste to rise together. After the waste compression disc 8 rises, it is driven by the screw slide 34 to move towards the discharge gap 36. Finally, the screw slide 34 moves the waste compression disc 8 and the cake-shaped waste out of the flared chamber 5.

[0065] One end of the lead screw slide 34 needs to extend a certain distance outward from the base 2. The dust box is provided with a discharge window leading to the outlet of the lead screw slide 34. When the waste compression plate 8 and the cake-shaped waste move to one end of the lead screw slide 34, the operator can remove the cake-shaped waste from the waste compression plate 8 through the discharge window. At the same time, when washing the machine tool 1, the operator can also spray water onto the surface of the machine tool 1 through the discharge window.

[0066] When machine tool 1 is being washed, in order to prevent the support end of the lead screw slide 34 from getting wet, a waterproof baffle (not shown in the figure) is installed above the support end of the lead screw slide 34.

[0067] To ensure that the waste compression disc 8 can carry up the cake-shaped waste material after compressing the waste, the following features are specifically designed:

[0068] The bottom of the waste compression disc 8 is formed with several inserts 37 evenly distributed along the circumference of the waste compression disc 8. The lower end of each insert 37 gradually tapers into a sharp point, and the outer wall of each insert 37 is formed with several barbs 38 evenly distributed along the circumference of the insert 37.

[0069] As the waste compression disc 8 gradually presses down onto the waste, each insert 37 inserts into the waste through its sharp lower end. When the waste compression disc 8 rises, the cake-shaped waste is brought up by several barbs 38 on each insert 37. When the operator removes the cake-shaped waste, they can simply pull it off with force.

[0070] To ensure that machine tool 1 is positioned directly above flared chamber 5, the following features are specifically designed:

[0071] A horizontal support plate 39 is provided above the base 2. Both ends of the support plate 39 are connected to the base 2 by several horizontal support rods 40. The bottom of the support plate 39 is connected to the flared waste trough 3 by four support columns 41 arranged in a matrix. The machine tool 1 is fixedly installed on the top of the support plate 39.

[0072] like Figure 1 As shown, there are gaps between several horizontal support rods 40 to facilitate the downward flow of waste materials and water into the flared chamber 5. The support strength of the support plate 39 is enhanced by several horizontal support rods 40 and four support columns 41, making the machine tool 1 more stable after installation.

[0073] To facilitate the installation of the transmission components within the receiving cavity 4, the following features are specifically provided:

[0074] The base 2 has an inlet / outlet groove 42 that communicates with the receiving cavity 4 on one side, and a cover plate 43 is provided on the inlet / outlet groove 42.

[0075] The cover plate 43 can be installed on the inlet / outlet channel 42 by means of hinge, so as to facilitate the opening and closing of the inlet / outlet channel 42. The inlet / outlet channel 42 facilitates the operator to install the transmission components in the receiving cavity 4.

[0076] Working principle:

[0077] After the workpiece is processed, a large amount of raw material residue will be attached to the machine tool 1. At this time, the surface of the machine tool 1 needs to be cleaned. In the traditional cleaning process, the waste will be flushed out of the machine tool 1 along with the water. The flowing liquid containing the waste and water will be directly discharged into the drain pipe (not shown in the figure). Since the waste can be reused by melting later, the waste not only easily clogs the drain pipe, but also causes a certain amount of material waste.

[0078] This device can collect the waste and water that are flushed out of the machine tool 1, and can separate the waste and water into solid and liquid components. After separation, the waste can be compressed into a cake shape by the waste compression mechanism, which facilitates the subsequent melting of the waste. The dust box is existing technology and is not shown in the figure.

[0079] The cleaning process for machine tool 1 when using this device is as follows:

[0080] Before cleaning, the workpieces and workpiece fixtures on the machine tool 1 need to be removed. Then, the surface of the machine tool 1 is rinsed with high-pressure water. The waste material will fall into the flared waste tank 3 from all sides of the machine tool 1 along with the water. During this process, the flowing liquid containing waste material and water will flow down into the columnar tube 6 along the flared chamber 5. After that, the water in the flowing liquid will be discharged through several sieve holes 7 on the filter screen plate 44, while the waste material will be temporarily stored in the columnar tube 6.

[0081] The lifting end of the dual-axis displacement mechanism drives the waste compression disc 8 to descend into the columnar tube 6, and the waste in the columnar tube 6 is compressed into a cake shape by the waste compression disc 8. At the same time, the upper plate 10 rises through the transmission component, and each pin 11 is inserted into the corresponding screen hole 7, so that each screen hole 7 is blocked, thereby preventing the waste from being embedded in several screen holes 7 when being compressed.

[0082] When the waste compression disc 8 rises again through the lifting end of the dual-axis displacement mechanism, the waste compression disc 8 will also move the cake-shaped waste upwards. After that, the waste compression disc 8 and the cake-shaped waste will be moved out of the flared chamber 5 through the horizontal displacement end of the dual-axis displacement mechanism. Finally, the operator can remove the cake-shaped waste attached to the waste compression disc 8 for melting.

[0083] The semi-circular cover 9 is used to prevent waste and water falling from the flared chamber 5 from splashing onto the dual-axis displacement mechanism. The special shape of the semi-circular cover 9 allows waste to flow down the outer wall of the semi-circular cover 9 with the water into the columnar tube 6, thereby preventing waste from adhering to the outer wall of the semi-circular cover 9.

[0084] Since machine tool 1 is mostly rectangular, the base 2 and the flared waste trough 3 need to be machined into rectangles during processing so that they can fit the shape of machine tool 1. During the washing process of machine tool 1, in order to prevent water and waste from splashing out of the flared waste trough 3, a removable baffle (not shown in the figure) can be added around the base 2. The baffle blocks the splashed waste and water, ensuring that the waste and water from machine tool 1 can only enter the flared waste trough 3.

[0085] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
