Description

Technical Field

[0001] This invention relates to the field of machine tool chip removal technology, specifically a chip removal mechanism for a large floor-type boring and milling machine. Background Technology

[0002] Large floor-type boring and milling machines are used in the field of modern machining to perform high-precision boring and milling operations on large and heavy parts. These machine tools are characterized by a large processing range, high precision, and strong load-bearing capacity, and are often used in aerospace, shipbuilding, and energy equipment manufacturing industries.

[0003] The chip removal mechanism of a large floor-type boring and milling machine is an indispensable part of the machine tool processing. Its function is to remove the chips generated during the processing in a timely manner to ensure the smooth progress of processing and the normal operation of the machine tool.

[0004] Early chip removal mechanisms used scraper-type chip conveyors. For the large amounts of chips generated during machining on large floor-type milling machines, the conveying speed was slow, causing chips to accumulate in the machining area. During continuous machining, chip accumulation affected the normal cutting of the tool and reduced machining accuracy. To solve this problem, existing technology uses Z-shaped chain plate chip conveyors. These conveyors use a chain to drive chain plates in continuous operation. The chain plates have protrusions that effectively scrape and carry large amounts of chips, promptly conveying them to the chip box on the factory floor. However, in practical use, using Z-shaped chain plate chip conveyors requires increasing the size of the chip pit and safety space in addition to the space occupied by the main machine bed and accessories. This increases the difficulty of chip collection when the length of space in the factory is limited. Adding a short L-side vertical steering chip conveyor increases the number of maintenance devices and costs. Due to space constraints, manual clearing of chip blockages is difficult.

[0016] This invention provides a chip removal mechanism for a large floor-type boring and milling machine. It has the following beneficial effects: 1. This invention activates the filter chip conveyor, allowing iron chips to flow into the chip conveying trough under the flushing of cutting fluid. The chips are then transported by gravity to the chip conveying inclined plate. The chip conveying inclined plate with a large angle design ensures smooth chip flow and reduces chip blockage. The open space reduces the risk of blockage. The iron chips eventually flow into the chip pit for collection. The angle of the chip conveying inclined plate can be adjusted by rotating the screw to optimize chip removal efficiency. The cutting fluid flows into the liquid collection tank and then into the water collection pit. This invention achieves efficient chip removal and collection in a limited space, reducing space requirements, maintenance costs, and the risk of chip blockage and the difficulty of unblocking. 2. This invention addresses the issue of metal chips falling from the filter chip conveyor onto the inclined chip chute during chip removal. The buffer inclined pad, which is the first point of contact, plays a crucial role. Its elasticity cushions the impact of the metal chips, reducing wear on the inclined chip chute, extending its service life, and preventing metal chips from splashing due to impact, thus maintaining a clean and safe chip removal environment. If the buffer inclined pad is damaged, pulling the unlocking lever allows for quick replacement through simple operation, avoiding disruptions to chip removal continuity due to the difficulty in replacing buffer components and ensuring efficient and stable chip removal. 3. This invention starts a servo motor, whose output rotates to drive a drive gear, which in turn drives a transmission gear, a rotating shaft, and a cleaning brush to clean the filter screen. Cutting fluid passes through the filter screen, while impurities are intercepted. The cleaning brush prevents impurities from accumulating and causing blockages. The intercepted impurities fall into a settling hopper. When they accumulate to a certain level, the drain valve is opened, and the impurities are discharged through the drain pipe. This effectively solves the problem of easy blockage in the fluid guide pipe, ensures smooth delivery of cutting fluid, and guarantees the stable operation of the chip removal system.

[0024] Working Principle: When using the chip removal mechanism of this large floor-type boring and milling machine, firstly, the filter chip conveyor 202 is activated. The iron chips generated during boring and milling, flushed by the cutting fluid, flow from the cutting table 5 along the guide slope 2092 into the filter chip conveyor 202 in the chip removal groove 201. The filter chip conveyor 202 transports the iron chips to the left end. Subsequently, under gravity, the iron chips fall onto the chip conveyor inclined plate 205 mounted on the inclined table 203. The chip conveyor inclined plate 205 adopts a large-angle design, ensuring that most iron chips fall automatically by gravity. At the same time, it reduces the friction between the iron chips and the chip conveyor inclined plate, making the chip conveying process smooth, with less iron chip accumulation and less clogging. Even if clogging occurs, compared to short-L-side deflecting chip conveyors, this location has a more open space, reducing the safety risk for personnel during evacuation. The iron chips eventually flow along the chip conveyor inclined plate 205 into the iron chip pit 2094 for collection. During this process, the lead screw 20 is rotated... 8. The rotation of the lead screw 208 drives the slider 207, which is threadedly connected to it, to slide on the inner wall of the mounting inclined platform 203. The slider 207 drives the chip conveyor plate 205 to rotate along the rotating support shaft 204 through the connecting rod 206, thereby adjusting the tilt angle of the chip conveyor plate 205. This adjustment function can flexibly adjust the chip sliding speed and path according to the characteristics of the chips and the actual chip removal situation, further optimizing the chip removal efficiency. After the cutting fluid passes through the filter chip conveyor 202, it flows into the collection tank 2102 of the collection tank 2101, and is then transported to the water collection pit 2104 by the liquid guide pipe 2103 connected to the bottom of the collection tank 2101. This achieves efficient chip removal and collection in a limited space without significantly increasing the space size, reducing maintenance costs, reducing the risk of chip blockage and the difficulty of unblocking, and solving the problems of increased space, cost and unblocking of existing Z-shaped chain plates and short L-side turning chip conveyors. Furthermore, during the chip removal process, when iron filings are conveyed from the filter chip conveyor 202 to the chip conveyor inclined plate 205, they will first come into contact with the buffer inclined pad 301. The buffer inclined pad 301 has a certain degree of elasticity, which can effectively buffer the impact force when the iron filings fall, avoiding excessive wear caused by the iron filings directly hitting the chip conveyor inclined plate 205, extending the service life of the chip conveyor inclined plate 205, and also reducing the situation where iron filings are scattered everywhere due to violent impact, ensuring a clean and safe chip removal working environment. When the buffer inclined pad 301 is damaged after long-term use, it can be quickly replaced by unlocking the pull rod 306. Specific operation... Yes, by pulling the unlocking lever 306, the insert block 302 is separated from the locking block 304. At this time, the locking block 304 compresses the spring 305 and slides into the slot 307. The insert block 302 disengages from the locking groove 303, and the damaged buffer tilt pad 301 can be pulled out from the inner wall of the chip conveyor inclined panel 205. Then, a new buffer tilt pad 301 is inserted, and the insert block 302 is once again locked into the locking groove 303. Under the elastic force of the spring 305, the locking block 304 locks the insert block 302 again, completing the quick replacement. This solves the problem in the prior art that it is difficult to quickly replace the buffer component after it is damaged, which affects the continuity of chip removal work. Finally, as the cutting fluid is collected by the collection tank 2102 and discharged from the guide pipe 2103 into the collection pit 2104, the filter mechanism 4 comes into play. First, the servo motor 4051 starts, and its output end rotates, driving the drive bevel gear 4052 to rotate. Since the drive bevel gear 4052 is meshed with the transmission bevel gear 4053, the transmission bevel gear 4053 rotates accordingly, thereby driving the rotating shaft 402 to rotate. The multiple cleaning brushes 403 fixed on the left side of the outer wall of the rotating shaft 402 will rotate together with the rotating shaft 402, cleaning the left side of the filter screen 401. The cutting fluid is cleaned from the side. When it passes through the filter screen 401, impurities are intercepted. The cleaning brush 403 prevents impurities from accumulating on the filter screen 401 and causing blockage. The intercepted impurities fall down the filter screen 401 into the settling hopper 4061 at the bottom. When the impurities in the settling hopper 4061 accumulate to a certain level, the drain valve 4063 is opened, and the impurities are discharged through the drain pipe 4062. Through the cleaning of the cleaning brush 403 and the draining of the drain assembly 406, the problem of easy blockage of the fluid guide pipe 2103 in the prior art is effectively solved, ensuring smooth delivery of the cutting fluid.
