Description

Technical Field

[0001] This invention relates to the field of CNC machine tool cleaning technology, and more specifically to a waste chip collection device for CNC machine tools. Background Technology

[0002] A chip collection device for CNC machine tools is a device specifically designed to collect the chips or shavings generated during the machining process of CNC machine tools. The purpose of this chip collection device is to effectively collect and process the chips generated by CNC machine tools, so as to improve the cleanliness of the work area, reduce waste accumulation and cleaning work, and ensure the proper disposal of waste to meet environmental protection and safety standards.

[0003] The China Patent Network published an invention patent with publication number CN118267811A entitled "A Waste Collection Device for CNC Machine Tools". This invention utilizes the cooperation of a wiping motor, rotating column, drive arm, drive rod, elliptical frame, transmission block, horizontal plate, horizontal bar, vertical plate, and a first brush layer to repeatedly wipe the filter screen. This automatically cleans the accumulated powder waste on the filter screen during CNC machine tool processing, eliminating the need for manual cleaning, reducing the user's labor intensity, and ensuring processing efficiency by eliminating the need to stop the machine for filter cleaning.

[0004] In the aforementioned publicly available documents, when the waste is pushed into the groove by the pusher plate set on the top plate, it is not possible to guide all the waste into the groove effectively. At the same time, it is necessary to control the wiping motor to cooperate with the cleaning mechanism to clean the filter screen, which increases the energy consumption of the equipment during operation. Summary of the Invention

[0005] To address the aforementioned shortcomings of existing technologies, this invention provides a waste chip collection device for CNC machine tools, which can effectively solve the problem of insufficient waste chip removal from CNC machine tool platforms in existing technologies, requiring additional energy-consuming equipment for auxiliary cleaning.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This invention provides a waste chip collection device for CNC machine tools, including a machining platform, and further comprising:

[0008] Two sets of support plates are used to support the processing platform. A collection hopper and a liquid collection tank are provided between the two sets of support plates, and the collection hopper is located above the liquid collection tank. A water storage component and a ratchet are rotatably installed on the support plates, and the water storage component and the ratchet are drivenly connected.

[0009] An automatic cleaning assembly for filtering waste chips from cutting fluid includes a filter belt and a rotating rod rotatably mounted on a support plate. A bevel gear set is provided on the ratchet to drive the filter belt to rotate. An incomplete gear one is provided on the side of the ratchet away from the bevel gear set. An incomplete gear two is provided on the rotating rod and meshes with the incomplete gear one. An actuating element is provided on the rotating rod, and a torsion spring is provided between the actuating element and the rotating rod. The torsion spring is used to always push the actuating element against the filter belt.

[0010] Furthermore, the processing platform includes mounting strips and support strips, and the mounting strips and support strips are perpendicular to each other in the same horizontal plane.

[0011] Furthermore, the bottom of the support bar is arched, and multiple sets of equidistant guide grooves are provided on the side of the support bar that contacts the mounting bar.

[0012] Furthermore, the water storage device is provided with a fan-shaped counterweight plate, which is used to keep the water storage device in a vertical state. When the water storage device is full of cutting fluid, the water storage device rotates on the support plate toward the side with the collection hopper and pours out the cutting fluid. After the cutting fluid in the water storage device is completely poured out, the fan-shaped counterweight plate drives the water storage device to reset and continue to collect cutting fluid.

[0013] Furthermore, the rotating shaft of the water storage component is equipped with a gear, and the gear is connected to the ratchet via a toothed plate. Both the upper and lower ends of the toothed plate are equipped with racks. When the gear rotates, it drives the toothed plate to descend. Subsequently, the toothed plate drives the ratchet to rotate. During the cycle of the water storage component rotating and resetting, the toothed plate is continuously pulled up and down, thereby continuously driving the ratchet to rotate in one direction.

[0014] Furthermore, the filter belt is rotatably mounted on the support plate via four sets of rotating shafts, and the filter belt covers the inlet of the liquid collection tank. The bevel gear set consists of two sets of bevel gears, one set is set on the rotating shaft, and the other set is coaxially set with the ratchet.

[0015] Furthermore, a fixed plate is rotatably mounted on the rotating rod, and one end of the fixed plate is connected to the support plate. The two ends of the torsion spring are respectively connected to the actuating member and the fixed plate. When the incomplete gear two rotates, it drives the actuating member away from the filter belt and compresses the torsion spring. When the incomplete gear two disengages from the incomplete gear one, the torsion spring drives the actuating member to reset and knock on the filter belt.

[0016] Furthermore, the actuating element is provided with multiple sets of balls that are equidistantly distributed.

[0017] Beneficial effects

[0018] The technical solution provided by this invention has the following advantages compared with the known prior art:

[0019] 1. The cutting fluid is collected by the water storage device. When the cutting fluid reaches a certain amount, the water storage device rotates towards the collection hopper, pouring out the cutting fluid to flush away the waste chips that have not actively fallen off the collection hopper. At the same time, in conjunction with the toothed plate, ratchet and bevel gear set, the filter belt is partially displaced each time the water storage device is tilted, preventing excessive waste chips from accumulating on the filter belt and affecting the filtration speed. At the same time, the waste chips on the filter belt can be discharged. Through the cooperation of the incomplete gear and the torsion spring, the actuating device is intermittently moved to knock the filter belt, shaking off the waste chips that have not fallen off the surface of the filter belt, thus achieving automatic cleaning.

[0020] 2. By setting the mounting strips and support strips perpendicular to each other, while fixing the workpiece, gaps are reserved for the discharge of production waste. During processing, the waste generated can be directly leaked out from between the mounting strips and support strips for filtration and collection. On the other hand, the support strips, which are equipped with guide grooves and are arched, can also guide some cutting fluid to both ends and flow into the water storage unit, realizing the function of intermittently tilting the water storage unit to rinse and collect the waste on the collection hopper.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] The present invention will be further described below with reference to embodiments.

[0032] A waste chip collection device for CNC machine tools, as shown in the attached figure. Figure 1-7 The processing platform 1 includes a mounting strip 11 and a support strip 12. The mounting strip 11 has multiple sets in a 'T' shape, and there is a 'convex' groove between adjacent mounting strips 11 to facilitate the installation and disassembly of the workpiece. The mounting strip 11 and the support strip 12 are perpendicular to each other in the same horizontal plane. The support strip 12 is located at the bottom of the mounting strip 11 and is used to fix the mounting strip 11. The support strip 12 is installed by a locking device to facilitate the installation, disassembly and maintenance of the processing platform 1.

[0033] Specifically, the bottom of the support bar 12 is arched, and the side of the support bar 12 that contacts the mounting bar 11 is provided with multiple sets of equally spaced guide grooves 121. The guide grooves 121 are used to guide the cutting fluid flow channel on the support bar 12, while the arched support bar 12 is used to guide the cutting fluid to flow to both sides.

[0034] In the above technical solution, by setting the mounting strips 11 and support strips 12 perpendicularly to each other, while fixing the workpiece, a gap is reserved for the discharge of production waste. During processing, the waste generated can be directly leaked out from between the mounting strips 11 and support strips 12 for filtration and collection. On the other hand, the support strips 12, which are provided with guide grooves 121 and are arched, can also guide some cutting fluid to both ends for subsequent cleaning.

[0035] Also includes:

[0036] Two sets of support plates 2 are used to support the processing platform 1. A collection hopper 3 and a liquid collection tank 5 are provided between the two sets of support plates 2. The collection hopper 3 is located above the liquid collection tank 5. The liquid collection tank 5 is located at the discharge end of the collection hopper 3. The size of the discharge end of the collection hopper 3 is smaller than the size of the feed end. It is used to collect waste chips and cutting fluid and discharge them into the liquid collection tank 5. A water storage component 21 and a ratchet 25 are rotatably installed on the support plate 2. The water storage component 21 and the ratchet 25 are drivenly connected. The water storage component 21 is located at both ends of the support bar 12 and collects cutting fluid. The ratchet 25 is located below the water storage component 21.

[0037] Specifically, the water storage component 21 is provided with a fan-shaped counterweight plate 22. The fan-shaped counterweight plate 22 is used to keep the water storage component 21 in a vertical state. When the water storage component 21 is full of cutting fluid, the water storage component 21 rotates on the support plate 2 toward the side where the collection hopper 3 is located and pours out the cutting fluid. After the cutting fluid in the water storage component 21 is completely poured out, the fan-shaped counterweight plate 22 drives the water storage component 21 to reset and continue to collect cutting fluid, so that the water storage component 21 automatically pours out when it is full of cutting fluid, and then washes away some of the accumulated waste chips on the collection hopper 3. After the cutting fluid in the water storage component 21 is poured out, the fan-shaped counterweight plate 22 assists the water storage component 21 to reset and continue to collect cutting fluid, so as to realize that the water storage component 21 swings intermittently and pours out cutting fluid to wash away some of the accumulated waste chips in the collection hopper 3.

[0038] Furthermore, a gear 23 is provided on the rotating shaft of the water storage component 21, and the gear 23 is driven to connect with the ratchet 25 through the toothed plate 24. Both the upper and lower ends of the toothed plate 24 are provided with racks. When the gear 23 rotates, it drives the toothed plate 24 to descend. Then the toothed plate 24 drives the ratchet 25 to rotate. During the cycle of the water storage component 21 rotating and resetting, the toothed plate 24 is continuously pulled up and down, thereby continuously driving the ratchet 25 to rotate in one direction. The rack provided at the upper end of the toothed plate 24 is located on the side of the gear 23 close to the collection hopper 3, and the rack provided at the lower end of the toothed plate 24 is located on the side of the ratchet 25 away from the liquid collection tank 5. This is used to drive the toothed plate 24 to descend when the water storage component 21 rotates toward the collection hopper 3, and then drive the ratchet 25 to rotate in the opposite direction.

[0039] An automatic cleaning assembly 4 for filtering waste chips from cutting fluid includes a filter belt 41 and a rotating rod 43 rotatably mounted on a support plate 2. A bevel gear set 26 is provided on the ratchet 25 to drive the filter belt 41 to rotate. When the filter belt 41 rotates on the support plate 2, it drives the filter belt 41 to move, thereby discharging the filtered waste chips. A sludge collection box (not shown in the figure) is provided at the bottom of the support plate 2 to collect waste chips. The filter belt 41 is rotatably mounted on the support plate 2 through four sets of rotating shafts 411, and the filter belt 41 covers the inlet of the liquid collection tank 5. The bevel gear set 26 consists of two sets of bevel gears, one set is set on the rotating shaft 411, and the other set is coaxial with the ratchet 25. When the ratchet 25 rotates, it cooperates with the bevel gear set 26 to drive the filter belt 41 to rotate.

[0040] The ratchet 25 has an incomplete gear 251 on the side away from the bevel gear set 26. The rotating rod 43 has an incomplete gear 431 that meshes with the incomplete gear 251. The rotating rod 43 has a toggle member 42, and a torsion spring 44 is provided between the toggle member 42 and the rotating rod 43. The torsion spring 44 is used to push the toggle member 42 against the filter belt 41. When the incomplete gear 251 rotates with the ratchet 25, it actuates the incomplete gear 431. Then, it actuates the rotating rod 43 to rotate and squeeze the torsion spring 44, so that the toggle member 42 disengages from the filter belt 41. When the incomplete gear 251 disengages from the incomplete gear 431, the restriction on the rotating rod 43 is removed. At this time, under the reset action of the torsion spring 44, the toggle member 42 is driven to knock the filter belt 41, shake off the waste on the filter belt 41, and automatically clean the filter belt 41.

[0041] A fixed plate 432 is rotatably mounted on the rotating rod 43, and one end of the fixed plate 432 is connected to the support plate 2. The two ends of the torsion spring 44 are respectively connected to the actuating member 42 and the fixed plate 432. When the incomplete gear 2 431 rotates, it drives the actuating member 42 away from the filter belt 41 and compresses the torsion spring 44. When the incomplete gear 2 431 disengages from the incomplete gear 1 251, the torsion spring 44 drives the actuating member 42 to reset and strike the filter belt 41.

[0042] In addition, the actuating member 42 is provided with multiple sets of balls 421 that are equidistantly distributed. The balls 421 can reduce the friction between the actuating member 42 and the filter belt 41, so that the movement of the filter belt 41 is smoother and not restricted by the actuating member 42.

[0043] In the above technical solution, the cutting fluid is collected by the water storage component 21. When the cutting fluid reaches a certain amount, the water storage component 21 is rotated toward the collection hopper 3 to pour out the cutting fluid and flush away the waste chips that have not actively fallen off the collection hopper 3. At the same time, in conjunction with the toothed plate 24, ratchet 25 and bevel gear set 26, the filter belt 41 is partially displaced every time the water storage component 21 is tilted, which prevents too much waste chips from accumulating on the filter belt 41 and affecting the filtration speed. Meanwhile, with the cooperation of the incomplete gear one 251, the incomplete gear two 431 and the torsion spring 44, the actuating component 42 is intermittently actuated to knock the filter belt 41, shaking off the waste chips that have not fallen off the surface of the filter belt 41, thus achieving automatic cleaning.

[0044] Working principle: The workpiece is mounted on the machining platform 1 by the clamping mechanism, and then machining is performed. The waste chips and cutting fluid generated during machining enter the collection hopper 3 through the gap between the mounting strip 11 and the support strip 12, and are filtered by the filter belt 41. The cutting fluid enters the collection tank 5 for collection, while the waste chips remain on the surface of the filter belt 41. During machining, some cutting fluid flows into the water storage component 21 through the support strip 12. When the amount of cutting fluid in the water storage component 21 reaches a certain level, the water storage component 21 tilts and pours into the collection hopper 3, cleaning up some of the waste chips accumulated in the collection hopper 3 and preventing waste chip accumulation. While the water storage component 21 rotates, the ratchet 25 is driven to rotate through the toothed plate 24. When the ratchet 25 rotates, it drives the bevel gear set 26. The rotating shaft 411 is rotated, which in turn drives the filter belt 41 to move. After the filter belt 41 moves multiple times, the waste accumulated on the filter belt 41 is moved to the side or bottom and poured into the collection box for collection. At this time, some waste will stick to the surface of the filter belt 41. When the ratchet 25 rotates, it will drive the incomplete gear 1 251 to rotate, which will drive the incomplete gear 2 431 to rotate. The incomplete gear 2 431 rotates and drives the actuating element 42 to rotate and disengage from the filter belt 41. At the same time, the torsion spring 44 is compressed. After the incomplete gear 1 251 and the incomplete gear 2 431 disengage, the torsion spring 44 returns to its original position and drives the actuating element 42 to strike the filter belt 41, causing it to vibrate and shake off the waste, thus automatically cleaning the filter belt 41.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
