Description

Technical Field

[0001] This invention relates to the field of CNC lathe chip cleaning technology, and more particularly to a rotary lathe chip cleaning device. Background Technology

[0002] Currently, CNC lathes primarily employ several methods for cleaning chips, including automatic chip conveyors, high-pressure cooling / rinsing systems, vacuum dust collection systems, and manual cleaning. While these automated systems can achieve continuous production or chip removal for specific applications, they generally suffer from high installation or initial setup costs, large footprints, unsuitability for wet machining, or stringent requirements for the machine tool's internal cooling channels and quick-change interfaces, leading to excessively high purchase and setup costs. Therefore, for machining plants processing small batches and small-volume workpieces with low levels of automation, manual cleaning is the most suitable and profitable option due to its significantly reduced costs and its adaptability to both conventional and CNC lathe types.

[0003] However, traditional manual cleaning methods have revealed significant technical problems in practical machining applications. During prolonged machining on lathes or CNC lathes, debris falls and accumulates on the machine tool base, requiring machine shutdown for cleaning. This shutdown disrupts production, reducing the overall production speed. Furthermore, after each machine shutdown, workers need to clean not only the sides of the lathe but also the base. Debris often accumulates in corners and crevices, making effective cleaning impossible. Over time, this residual debris combines with the coolant to form sludge, further hindering the overall cleaning of the machine tool.

[0004] Therefore, there is an urgent need for a rotary lathe debris cleaning device that is simple in structure, low in installation cost, and capable of automatic collection, drainage, and efficient scraping cleaning, in order to solve the problems of manual cleaning causing downtime and affecting production speed, and debris accumulation in the corners and gaps of the base, which easily forms sludge and cannot be effectively cleaned. Summary of the Invention

[0005] To address the aforementioned technical problem, a rotary lathe debris cleaning device is provided. This invention utilizes a three-groove collection tray in conjunction with a guide frame to create an upper collection area and a lower inclined cleaning area. Combined with a synchronously belt-driven oil-spraying scraping mechanism and an air-jet brush mechanism, it achieves automatic cyclic cleaning of lathe debris.

[0006] To achieve the above objectives, the present invention provides a rotary lathe chip cleaning device, comprising: a base, a guide frame, a collection tray, a first motor, a second motor, a synchronous belt, an oil spraying mechanism, and an air spraying mechanism; The base is provided with a collection chamber and power chambers located on both sides of the collection chamber; The guide frame consists of two pieces and is installed on opposite side walls inside the collection chamber, forming a collection and processing space between the two guide frames; The collection tray is installed between the two guide frames. The central shafts at both ends of the collection tray are installed in the rotating shaft holes opened on the side wall of the collection cavity through bearings. The collection tray has three centrally symmetrically arranged grooves, and a dividing end is formed between two connected grooves. The first motor is fixedly installed in one of the power chambers, and the first motor is connected to the central shaft of the collection tray to drive the collection tray to rotate; Two synchronous belts are provided and positioned between the two guide frames. Each synchronous belt is fitted onto a corresponding set of synchronous pulleys. Both ends of the synchronous belts extend into the power chamber through belt holes opened in the inner sidewall of the collection chamber. Each set of synchronous pulleys includes a driven pulley and a driving pulley. The two sets of driven pulleys are respectively hinged to the corresponding sidewall of the power chamber via hinge frames. The two sets of driving pulleys are connected to a second motor fixed in the power chamber. The oil injection mechanism and the jet injection mechanism are respectively located at both ends of the bottom side of the collection tray and are fixedly connected to the synchronous belt. A guide column is also horizontally fixedly installed inside the collection cavity. The oil injection mechanism and the jet injection mechanism are guided and cooperated with the guide column. The synchronous belt drives the oil injection mechanism and the jet injection mechanism to move along the groove to clean it.

[0007] Furthermore, a cover plate is installed inside the collection chamber, which covers the upper side of the guide frame and is sealed between the guide frame and the guide frame.

[0008] Furthermore, sealing strips are installed on the three dividing ends of the collection tray, and sealing strips are also installed on both ends of the collection tray along the trajectory of the groove; the sealing strips at both ends of the collection tray are in sealing contact with the inner wall of the collection cavity and the side wall of the cover plate installed on one side of the collection cavity, respectively.

[0009] Furthermore, the inner wall of the collection chamber is also provided with a guide shaft hole, an air outlet hole, and an oil outlet hole; Two openings are provided on the other inner wall of the collection chamber near the upper end, and the two openings are used to install oil pipes and air pipes, respectively.

[0010] Furthermore, the guide frame and the collection tray cooperate with each other and are separated to form three independent areas, namely the collection area located above, the oil spraying and cleaning area located on one side, and the air spraying and drying area located on the other side; the oil spraying mechanism is located in the oil spraying and cleaning area, and the air spraying mechanism is located in the air spraying and drying area.

[0011] Furthermore, a chassis is fixedly installed at the bottom of the collection tray, and the chassis is fixedly connected to the side wall of the collection chamber and the guide frame near the bottom on all four sides. The chassis has a structure with a raised center and curved surfaces extending downward on both sides. When the collection tray is in working condition, one of the dividing ends is in sealed contact with the center of the chassis to isolate the jet drying area from the oil spray cleaning area.

[0012] Furthermore, the guide frame includes a guide plate located on the upper side, an arc plate fixed to the lower end of the guide plate, and a vertical plate disposed at the lower end of the arc plate; The guide plate is arc-shaped and its upper end contacts the side wall of the collection chamber; the curvature of the inner side wall of the arc plate is the same as the curvature of the dividing end of the collection tray, and the side wall of the dividing end is in sliding and sealing contact with the inner wall of the arc plate; the side wall of the vertical plate near the bottom is sealed and fixed to the side wall of the base; the vertical plate and the guide plate are both fixed with connecting frames near the side wall of the collection chamber, and the connecting frames are fixed in the collection chamber by bolts.

[0013] Furthermore, the oil injection mechanism includes a first sliding sleeve and two first mounting brackets fixed on the first sliding sleeve; The two first mounting brackets are staggered and connected by an inclined arc plate. A scraper is installed on the arc plate to slide in contact with the side wall of the groove. A fuel injection box adapted to the shape of the arc plate is installed inside the arc plate. Several fuel injection nozzles are installed on both sides of the fuel injection box, all inclined towards the groove. The fuel injection box is connected to an external fuel supply system through a pipe. The first mounting bracket is fixedly connected to the side wall of the timing belt by a mounting block.

[0014] Furthermore, the jet mechanism includes a second sliding sleeve slidably sleeved on the guide post, and two second mounting brackets are fixed on the second sliding sleeve; Two second mounting brackets are fixedly mounted with arc-shaped mounting plates, and brushes that contact the sidewalls of the grooves are mounted on the outer arc surfaces of the mounting plates; the second mounting brackets are fixedly connected to the timing belts via mounting blocks; the jet mechanism also includes a jet box, which has several jet nozzles for blowing warm gas toward the grooves, and the jet box is connected to an external air pump via pipes.

[0015] By adopting the above technical solution, the present invention has the following advantages compared with the prior art: 1. The present invention provides a rotary lathe chip cleaning device, which forms three functional areas—a collection area, an oil spray cleaning area, and an air spray drying area—through the cooperation of three grooves on the collection plate and the guide frame. The intermittent rotation of the collection plate enables the workstation switching of the three grooves in a cycle, so that while one groove receives chips, the other two grooves are respectively washed and dried. This achieves continuous automatic chip cleaning without stopping the machine, avoiding the problem of reduced production efficiency caused by manual machine stoppage for cleaning, and at the same time reducing the labor intensity and safety hazards of workers.

[0016] 2. The present invention provides a rotary lathe chip cleaning device, wherein the oil spraying mechanism is equipped with a scraper and an oil spray nozzle, and the air spraying mechanism is equipped with a brush and an air spray nozzle. Driven by a synchronous belt, the device moves back and forth along the axial direction of the groove, performing a dual cleaning method on the inner wall of the groove, ensuring that the metal chips attached to the surface of the groove are completely removed. This effectively solves the problem in the prior art where chips accumulate at the corners and gaps of the base, forming sludge with the coolant, resulting in poor overall cleaning effect of the machine tool.

[0017] 3. The present invention provides a rotary lathe chip cleaning device. The present invention adopts a structure with a base-built collection tray and a synchronous belt driven cleaning mechanism. The overall structure is simple and compact, with low manufacturing cost. It can be directly installed on ordinary lathes or CNC lathes. Compared with the existing automatic chip conveyor, high-pressure cooling and flushing system or vacuum dust collection system, it does not require complicated supporting equipment and pipeline system, which greatly reduces the equipment investment cost. It is particularly suitable for the use needs of small and medium-sized processing plants. Attached Figure Description

[0028] like Figures 1 to 9 As shown, the present invention provides a rotary lathe chip cleaning device, comprising: a base 2, a guide frame 10, a collection tray 11, a first motor 15, a second motor 13, a timing belt 12, an oil spraying mechanism 16, and an air spraying mechanism 17; The base 2 is hollow inside and divided into three chambers by partitions: a central collection chamber 3, and two power chambers 4 located to the left and right of the collection chamber 3. The collection chamber 3 is used to collect the mixture of debris and coolant generated during lathe machining, while the two power chambers 4 are used to install the first motor 15 and the second motor 13. On the left and right inner walls of the collection chamber 3, there are respectively a belt hole 5 for the synchronous belt 12 to pass through, a guide shaft hole 6 for the guide post 24 to pass through, and a rotating shaft hole 7 for mounting the central shaft of the collection disc 11 via bearings. In addition, an air outlet hole 8 for discharging air and an oil outlet hole 9 for discharging coolant containing debris are provided at the bottom or lower side wall of the collection chamber 3. On the other inner wall opposite the side wall with the oil outlet hole 9, near the upper end, there are two openings for fixing and allowing oil pipes and air pipes to pass through, respectively.

[0029] There are two guide frames 10, which are symmetrically fixedly installed on the left and right walls inside the collection chamber 3. A central space for collecting and processing debris is formed between the two guide frames 10. The specific structure of each guide frame 10 is as follows, taking the right guide frame as an example: The guide frame 10 includes a guide plate 20, an arc plate 21, a vertical plate 22, and a connecting frame 23. The guide plate 20 is located at the top of the guide frame 10 and is an arc-shaped plate that curves downwards. Its upper end is fixedly connected to the inner wall of the right side of the collection chamber 3 by welding or bolts and is in close contact. The arc plate 21 is fixed to the lower end of the guide plate 20 and extends inwards. The inner wall of the arc plate 21 is arc-shaped, and its curvature facing the collection tray 11 is exactly the same as the curvature of the dividing end 18 of the collection tray 11 (described later). The vertical plate 22 is fixed to the lower end of the arc plate 21 and extends vertically downwards. The side wall of the vertical plate 22 near the bottom is sealed and fixedly connected to the side wall of the base 2 by welding or sealing strips. The vertical plate 22 and the guide plate 20 are both fixed with connecting frames 23 near the side wall of the collection chamber 3. The connecting frames 23 are detachably fixed to the side wall of the collection chamber 3 by bolts, thereby stabilizing the entire guide frame 10 in the collection chamber 3.

[0030] The collecting tray 11 is installed between two guide frames 10. Its central shafts at both ends are mounted via rolling bearings in the rotating shaft holes 7 on the left and right side walls of the collecting cavity 3, allowing the collecting tray 11 to rotate freely around its central axis. The main body of the collecting tray 11 is cylindrical, with three grooves of the same shape and size on its circumference. These three grooves are centrally symmetrically distributed along the circumference, i.e., one groove is placed every 120 degrees. A raised dividing end 18 is formed between two connected grooves. To improve sealing, a wear-resistant rubber or silicone sealing strip is installed on the top surface of each dividing end 18 via a slot. Simultaneously, sealing strips are also installed on the left and right end faces of the collecting tray 11 along the trajectory of the three grooves. After installation, the sealing strip on the left end face makes sealing sliding contact with the left inner wall of the collecting cavity 3, and the sealing strip on the right end face makes sealing sliding contact with the right inner wall of the collecting cavity 3.

[0031] The first motor 15 is fixedly installed at the bottom of the power chamber 4 on one side. The output shaft of the first motor 15 is connected to a gearbox, and the output shaft of the gearbox is then fixedly connected to the central shaft on the left side of the collection tray 11 via a coupling. When the first motor 15 is started, it can drive the collection tray 11 to rotate intermittently at a set angle, for example, 120 degrees.

[0032] Two synchronous belts 12 are arranged parallel to each other between the two guide frames 10. The left and right ends of each synchronous belt 12 pass through belt holes 5 opened on the left and right side walls of the collecting chamber 3, respectively, and extend into the corresponding power chamber 4. Inside the power chamber 4, a synchronous pulley is fitted at both ends of each synchronous belt 12. The synchronous pulley on one side is rotatably hinged to the side wall of the power chamber 4 via a hinge frame; this pulley is the driven pulley. The synchronous pulley on the other side is fixedly connected to the output shaft of a second motor 13, the housing of which is bolted to the side wall of the right-side power chamber 4. When the second motor 13 starts, it drives the synchronous pulley on it to rotate, thereby driving the synchronous belt 12 to perform reciprocating linear motion.

[0033] Both the oil injection mechanism 16 and the air jet mechanism 17 are located below the collection tray 11, at opposite ends of the bottom. Specifically, the oil injection mechanism 16 is located near the oil outlet 9, and the air jet mechanism 17 is located near the air outlet 8. Both mechanisms are fixedly connected to the side wall of the synchronous belt 12 via specially designed mounting blocks. When the second motor 13 drives the synchronous belt 12 to move, the synchronous belt 12 simultaneously drives the oil injection mechanism 16 and the air jet mechanism 17 to reciprocate along the axial direction of the collection tray 11, thereby cleaning the grooves at different work positions.

[0034] Inside the collection chamber 3, near the right side wall, a cover plate 14 is vertically installed. This cover plate 14 includes a horizontal section and a vertical section. The horizontal section covers the right guide frame 10, and its edge is sealed to the guide frame 10 using a sealing strip. The vertical section extends downwards from the right end of the horizontal section. A cavity, or storage area, is formed between the lower part of the cover plate 14 and the right guide frame 10. When not in operation, the oil injection mechanism 16 and the air jet mechanism 17 can retract into this storage area to avoid interference with the rotating collection tray 11. Simultaneously, as before, the sealing strip on the right end face of the collection tray 11 makes sliding sealing contact with the left side wall of the cover plate 14.

[0035] A base plate 19 is fixedly installed at the bottom of the collection tray 11. The four edges of the base plate 19 are tightly fixed to the front, rear, left, and right side walls of the collection chamber 3, as well as the left and right guide frames 10 near the bottom, through welding and sealant, thereby completely sealing the bottom of the collection chamber 3. The base plate 19 has a structure where the center rises upwards and extends downwards to the left and right sides, forming an arc-shaped concave surface. When the collection tray 11 is in a specific working position, such as... Figure 6 As shown, one of the dividing ends 18 rotates to its lowest point and comes into close contact with the central raised part of the chassis 19. With the sealing strip installed on the dividing end 18, the space above the chassis 19 is divided into two isolated areas: the oil spray cleaning area on the left and the air spray drying area on the right.

[0036] The fuel injection mechanism 16 includes a first sliding sleeve 25, a first mounting bracket 26, an arc-shaped plate, a scraper 27, and a fuel injection tank 28. The first sliding sleeve 25 is slidably mounted on a guide post 24 horizontally fixed within the collection chamber 3. Both ends of the guide post 24 are fixed to the side walls of the collection chamber 3. The first sliding sleeve 25 can slide freely along the guide post 24, providing guidance and support for the movement of the fuel injection mechanism 16. Two first mounting brackets 26 are fixed to the first sliding sleeve 25, arranged in a staggered manner. The bottoms of the two first mounting brackets 26 are fixedly connected by a downwardly inclined arc-shaped plate. A scraper 27 is bolted to the lower edge of the arc-shaped plate. The scraper 27 is made of wear-resistant silicone or polyurethane material, its shape matches the inner wall shape of the groove, and it slides in contact with the side wall of the groove during operation. A fuel injection tank 28, matching the shape of the arc-shaped plate, is installed correspondingly within the internal cavity of the arc-shaped plate. Multiple fuel injectors are installed on the left and right side walls of the fuel injection tank 28, with their outlets all inclined towards the groove. The fuel injection tank 28 is connected to an external fuel supply system via hoses. The first mounting bracket 26 is fixedly connected to the side wall of the timing belt 12 via a mounting block. When the timing belt 12 moves, it drives the entire fuel injection mechanism 16 to reciprocate along the axial direction of the groove. During the movement, the scraper 27 scrapes the inner wall of the groove, while the fuel injectors spray coolant onto the inner wall of the groove, together completing the cleaning process.

[0037] The jet mechanism 17 includes a second sliding sleeve 32, a second mounting bracket 29, a mounting plate, a brush 30, and a jet box 31. The second sliding sleeve 32 is slidably fitted onto the same or another horizontally fixed guide post. Two second mounting brackets 29 are fixed to the second sliding sleeve 32. An arc-shaped mounting plate is fixedly mounted on the two second mounting brackets 29. The brush 30 is fixed to the outer arc surface of the mounting plate by adhesive or bolts. The bristles of the brush 30 contact the sidewall of the groove during operation. The jet mechanism 17 also includes a separate jet box 31, which has multiple jet nozzles facing the groove. The jet box 31 is connected to an external air pump via a hose and can heat the gas to spray warm air at 30-40 degrees Celsius. The second mounting bracket 29 is also fixedly connected to the sidewall of the synchronous belt 12 via a mounting block. When the timing belt 12 moves, it drives the jet mechanism 17 to move back and forth along the groove axis. The brush 30 sweeps away residual debris, and at the same time, the jet nozzle blows out warm air to dry and clean the groove.

[0038] Workflow: In operation, the device of this embodiment first drives the collection tray 11 to rotate via the first motor 15, so that one groove faces upwards in the collection area, while the other two grooves are located in the oil spray cleaning area and the air spray drying area, respectively. Coolant containing debris generated during lathe machining falls into the upper groove. Once the groove is full or a set time has elapsed, the coolant supply is stopped, and the first motor 15 drives the collection tray 11 to rotate 120 degrees. At this time, the groove filled with debris moves into the oil spray cleaning area, the groove in the original air spray drying area moves into the collection area to begin a new collection process, and the groove in the original oil spray cleaning area moves into the air spray drying area. Subsequently, the second motor 13 starts, driving the oil spray mechanism 16 and the air spray mechanism 17 via the synchronous belt 12 to perform axial reciprocating cleaning of the grooves in their respective areas. The oil spray mechanism 16 thoroughly removes the debris from the grooves through the mechanical scraping of the scraper 27 and the hydraulic flushing of the nozzles, and the debris is discharged with the coolant from the oil outlet 9; the air spray mechanism 17 removes residual debris and coolant from the grooves and dries them through the sweeping of the brush 30 and the blowing of warm air. After cleaning is complete, the cleaning unit returns to the storage area under cover 14, awaiting the next cycle.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. 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 or all of the technical features therein.
