DETAILED DESCRIPTION
[0019] Clearly, the described embodiments are merely a part of the embodiments of the present utility model, rather than all the embodiments.
[0020] Referring to Figures 1-4 A milling machine chip removal structure, comprising a milling machine workbench 1, the milling machine workbench 1 has a T-shaped groove 2, the chip removal structure comprises a winding assembly 3 located at one end of the milling machine workbench 1, the winding assembly 3 comprises a retractable pull rope 4, the free end of the pull rope 4 is connected with a scraper 5, the bottom of the scraper 5 is fixedly connected with a plurality of T-shaped scraping heads 6 with the same shape as the cross section of the T-shaped groove 2, and the T-shaped scraping heads 6 can slide in the T-shaped groove 2.
[0021] The milling machine chip removal structure drives the scraper connected to the free end of the pull rope to move along the milling machine workbench by setting the winding assembly and the retractable pull rope, and the plurality of T-shaped scraping heads at the bottom of the scraper can slide in the T-shaped groove. When the winding assembly winds the pull rope, the scraper drives the T-shaped scraping heads to move in the T-shaped groove, pushes the iron chips accumulated in the groove to the end of the workbench for centralized collection, facilitates subsequent processing, and thus realizes rapid and efficient chip removal in the groove.
[0022] The structure is simple in design, can effectively solve the problem that the iron chips accumulated in the T-shaped groove of the traditional milling machine are difficult to clean, significantly reduces the workload of manual cleaning, and workers only need to move the scraper 5 to the end away from the winding assembly and insert it into the T-shaped groove 2, thereby improving the work efficiency. Meanwhile, the scraper and the T-shaped scraping head are closely matched, the chip removal effect is good, and the adverse effects of the iron chips on the workpiece machining precision and equipment service life are avoided.
[0023] It should be noted that the number of T-shaped scraping heads 6 of the device can be less than the total number of T-shaped grooves 2, or can be equal to the total number of T-shaped grooves 2, and workers can select a suitable number according to specific working conditions.
[0024] The pull rope 4 has a hollow structure, one end of the pull rope 4 connected with the winding assembly 3 is communicated with a fluid supply device, each T-shaped scraping head 6 has a fluid nozzle 9 on the side close to the winding assembly 3, and the pull rope 4 is communicated with the fluid nozzle 9.
[0025] In the structure, the pull rope is designed to be hollow, and one end connected with the winding assembly is communicated with the fluid supply device, so that high-pressure fluid can be transported in the pull rope. The fluid is transported to the T-shaped scraping head through the internal channel of the pull rope, and high-pressure fluid is sprayed out through the fluid nozzle arranged on the side of each T-shaped scraping head close to the winding assembly, so as to flush the iron chips in the T-shaped groove. In combination with the mechanical pushing action of the scraper, the iron chips in the T-shaped groove are quickly cleaned and discharged.
[0026] By synchronously spraying high-pressure fluid in the process of removing iron filings, the structure not only improves the thoroughness of iron filings cleaning, but also effectively prevents fine iron filings from remaining at the bottom of the T-shaped groove, further reducing the need for manual cleaning. Compared with the pure mechanical scraping method, the combination of fluid flushing can significantly improve the efficiency of removing iron filings, reduce the risk of equipment wear and tear, and prolong the service life of the milling machine table and the T-shaped groove.
[0027] The winding assembly 3 comprises a winding wheel 10 and a rotary motor in transmission connection with the winding wheel 10. The winding wheel 10 is hollow inside and has an open end. One end of the pull rope 4 is fixed to the winding wheel 10, and the pull rope 4 communicates with the hollow chamber inside the winding wheel 10 through the communication hole 13 provided in the winding wheel 10. The open end of the winding wheel 10 is rotatably connected to the cylinder 11 through the sealing bearing 12, and the cylinder 11 is connected to the liquid pump.
[0028] In the present iron removal structure, the winding assembly comprises a hollow winding wheel and a rotary motor in transmission connection therewith. The rotary motor drives the winding wheel to rotate, realizing the control of winding and unwinding of the pull rope. One end of the pull rope is fixed to the winding wheel and communicates with the hollow chamber inside the winding wheel through the communication hole provided inside the winding wheel. The liquid pump delivers high-pressure fluid to the chamber through the cylinder connected to the open end of the winding wheel, and then delivers the fluid to the fluid injection port of the T-shaped scraper head through the pull rope. The synchronous iron removal and fluid flushing are realized by cooperating with the winding and unwinding action of the pull rope. By connecting the pull rope with the hollow structure of the winding wheel and combining the sealing bearing and the cylinder structure design, the sealing and continuity of the fluid passage can be maintained during the winding process.
[0029] As an embodiment, the scraper 5 has a cavity 16, the pull rope 4 is fixed to the scraper 5 and communicates with the cavity 16, and the scraper 5 is provided with a plurality of first machining holes 17 at the bottom and communicating with the cavity 16. The T-shaped scraper head 6 is provided with an L-shaped hole, one end of which communicates with the first machining hole 17 and points to the winding assembly 3.
[0030] In the present iron removal structure, the scraper is provided with a cavity inside, and the pull rope is fixed to the scraper and communicates with the cavity, so that the high-pressure fluid is delivered through the pull rope and then enters the cavity of the scraper. A plurality of first machining holes are provided at the bottom of the scraper to guide the fluid from the cavity to the T-shaped scraper head. The T-shaped scraper head is provided with an L-shaped hole inside, one end of which communicates with the first machining hole and the other end of which sprays towards the winding assembly, forming a high-pressure fluid flow path for flushing and cleaning the iron filings in the T-shaped groove, and realizing efficient iron removal in cooperation with the movement of the scraper.
[0031] In order to reduce the processing difficulty, the T-shaped scraping head 6 comprises a vertical part 7 and a horizontal part 8, the vertical part 7 is fixed with the bottom surface of the scraping plate 5, the vertical part 7 is provided with a vertical second processing hole 18, the horizontal part 8 is provided with a horizontal third processing hole 19 which is communicated with the second processing hole 18, and the L-shaped hole comprises the second processing hole 18 and the third processing hole 19. The structure design that the vertical part and the horizontal part are separated to form holes avoids the high-difficulty operation of processing a complete L-shaped hole at one time, significantly simplifies the manufacturing process of the T-shaped scraping head, and improves the processing precision and the yield.
[0032] A high-pressure nozzle 20 is arranged at the end of the third processing hole 19, wherein the high-pressure nozzle 20 can be a Y-shaped two-nozzle structure, and the two nozzles are inclined to point to the inner walls of the two sides of the T-shaped groove 2. By arranging the high-pressure nozzle at the fluid outlet end, the fluid ejection speed and the flushing strength can be significantly improved, so that fine or firmly adhered iron filings can also be effectively removed, and the complete iron removal is improved.
[0033] The scraping plate 5 comprises a right-angle corner plate 14, the three open sides of the corner plate 14 are sealed by a sealing plate 15, and a cavity 16 is arranged in the space surrounded by the corner plate 14 and the scraping plate 5. The cavity 16 is formed in a split molding manner, thereby reducing the processing difficulty.
[0034] As a working mode, in use, the rotary motor drives the winding wheel to rotate, and controls the extension and winding of the pull rope (when the pull rope is extended, the worker needs to install the scraping plate 5 and the T-shaped scraping head 6 into the T-shaped groove 2 of the milling machine workbench 1 from the other end). One end of the pull rope is fixed on the winding wheel and is communicated with the high-pressure fluid delivered by the liquid pump through the internal channel. The fluid enters the cavity of the scraping plate through the internal channel of the pull rope, and enters each T-shaped scraping head through the first processing hole at the bottom. The T-shaped scraping head is provided with an L-shaped channel, the fluid enters the vertical second processing hole, and then is guided to the high-pressure nozzle through the horizontal third processing hole and is sprayed out, thereby forming directional high-pressure fluid flushing. In the process of removing iron filings, the scraping plate drives the plurality of T-shaped scraping heads to slide along the T-shaped groove, and the iron filings accumulated in the groove are mechanically pushed. At the same time, the fluid sprayed out by the high-pressure nozzle flushes, peels and carries the iron filings in the groove. The synchronous control of the winding assembly makes the scraping plate reciprocate along the T-shaped groove, thereby realizing the rapid and complete removal of the iron filings in the T-shaped groove of the milling machine workbench. The whole process does not need a large amount of manual intervention, and the automation degree and the cleaning efficiency of the milling machine are effectively improved.
