Description

Technical Field

[0001] This utility model relates to the field of chip removal technology for machining centers, and in particular to a chip removal mechanism for a composite machining center. Background Technology

[0002] A machining center is a mechanical device used for metal processing, while a composite chip removal mechanism is a device used to handle metal cutting chips. Its function is to remove the generated metal chips or waste from the processing area, ensuring the smooth progress of the processing. Common machining center composite chip removal mechanisms use devices such as robotic arms or conveyor belts to transport metal chips from inside the machining center. Specifically, it usually includes several parts: a collection device, a conveying device, a separation device, and a processing device.

[0003] In existing machining centers, waste chips are collected by the self-flowing mixture of waste chips and coolant, settling into a chip removal trough, and then being pushed out of the machining center by a pushing mechanism inside the collection trough. However, this mixture usually includes some long filaments of waste chips, which easily get stuck on the inner wall of the machining table. Other fine waste chips are easily coated with cutting fluid and adhere to the machining table. Both of these situations cause blockages in the normal flow of waste chips, hindering their removal.

[0004] Therefore, a new type of chip removal mechanism is needed to solve this problem. Utility Model Content

[0012] Furthermore, a guide frame is fixed at the bottom of the processing table, and a differential hydraulic cylinder passes through the center of the guide frame. The output end of the differential hydraulic cylinder is welded to the bottom of the lifting plate.

[0013] Furthermore, the bottom of the hollowed-out inclined plate is rotatably connected to the inner wall of the processing table via a hinge shaft, a liquid-retaining eave formed on the edge of the processing table is provided directly above the hollowed-out inclined plate, and a surrounding plate is provided directly below the hinge rod.

[0032] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0033] like Figure 1-Figure 5As shown in the figure, this embodiment provides a chip removal mechanism for a composite machining center, including a machining center housing 1, a moving mechanism, a cleaning mechanism, and a chip removal mechanism. The machining center housing 1 includes a base 101, a machining table 102, and a fixture base 103. The base 101 is a supporting and sealing structure inside the machining center. The machining table 102 is a support for workpiece machining. The fixture base 103 is a machining table 102 with a fixture mounted on it. The machining tool of the machining center is mounted directly above it. The moving mechanism includes a moving lead screw 2 with positive and negative threads on both sides, which can drive the nozzles on both sides to move synchronously in opposite directions. The cleaning mechanism includes a lifting rod 201 and a coolant nozzle 202. The coolant nozzle 202 is connected to the same cutting fluid used during tool machining to prevent the cutting fluid from mixing with other fluids. The liquid cannot be recycled. The chip removal mechanism includes a chip removal spiral cutter 301, a chip removal chain plate 501, a hollow inclined plate 4, and a scraper 7. The chip removal spiral cutter 301 rotates at low speed and discharges waste chips from the collection tank through the principle of spiral feeding. The moving screw 2 is rotatably connected to the machining center housing 1, and a first motor 203 is installed on one end of the outside. A second motor 302 is installed on one end of the outside of the chip removal spiral cutter 301, and a third motor 502 is installed on one side of the outside of the hollow inclined plate 4. A hinge rod 401 is hinged to the bottom of the hollow inclined plate 4, and a lifting plate 402 is hinged to the bottom of the hinge rod 401. An electric push rod 701 is fixedly connected to one side of the inner wall of the scraper 7. The lifting rod 201 is slidably connected to the moving screw 2, and a coolant nozzle 202 is fixed to the bottom of the lifting rod 201.

[0034] like Figures 1-4 As shown, the base 101 has first chip removal grooves 3 formed on both sides of the bottom. The bottom of the first chip removal groove 3 has a hollow structure, which can filter out the waste liquid during chip removal and collect it in the recycling chamber 6. One end of the first chip removal groove 3 is connected to the second chip removal groove 5. The second chip removal groove 5 has a directional structure. The chip removal spiral blade 301 is rotatably installed with the first chip removal groove 3, and the chip removal chain plate 501 is slidably installed with the second chip removal groove 5.

[0035] like Figure 2 and Figure 3 As shown, a guide frame 404 is fixed at the bottom of the processing table 102. A differential hydraulic cylinder 403 passes through the center of the guide frame 404. The output end of the differential hydraulic cylinder 403 is welded to the bottom of the lifting plate 402. The differential hydraulic cylinder 403 is a high-speed hydraulic mechanism that drives the lifting plate 402 to move at high speed, which can be converted into high-speed vibration of the hollow inclined plate 4, thereby accelerating chip removal.

[0036] like Figure 2 and Figure 3As shown, the bottom of the perforated inclined plate 4 is rotatably connected to the inner wall of the processing table 102 via a hinge shaft. A liquid-retaining eave 406 formed on the edge of the processing table 102 is provided directly above the perforated inclined plate 4. A surrounding plate 405 is provided directly below the hinge rod 401. The perforated inclined plate 4 and the liquid-retaining eave 406 are in inclined contact. When the perforated inclined plate 4 shakes, it can hit the bottom of the liquid-retaining eave 406 to further accelerate the chip removal. The liquid-retaining eave 406 can prevent waste liquid from entering the processing table 102 from the gaps in the perforated inclined plate 4. The waste liquid can be discharged from the perforation and transferred into the cavity on one side of the surrounding plate 405, and then fall into the recovery chamber 6.

[0037] like Figure 5 As shown, there are two scrapers 7, both of which are slidably connected to the inner wall of the fixture base 103. The outer wall of the electric push rod 701 is fixed to the bottom of the fixture base 103 through a ring sleeve. The scrapers 7, in conjunction with the cleaning action of the nozzle at the top, push out the adhering waste mixture.

[0038] like Figure 1 , Figure 3 as well as Figure 4 As shown, the coolant nozzle 202 supplies coolant through the coolant pipe 204.

[0039] like Figure 1 As shown, a recovery chamber 6 is formed at the bottom of the machining center housing 1. A discharge pipe 601 is inserted into the outer wall of the recovery chamber 6. The recovery chamber 6 is connected to the first chip removal groove 3 and the second chip removal groove 5.

[0040] The working principle of this device is as follows: When this device is in use, the workpiece is clamped on the fixture 103 and the machining tool is installed directly above the fixture 103. The tool is equipped with a cutting fluid nozzle. The debris generated by cutting the workpiece is left on the top of the machining table 102 and the top of the fixture 103. At this time, the first motor 203 drives the moving lead screw 2 to rotate. The positive and negative threads of the moving lead screw 2 drive the two sets of lifting rods 201 to move synchronously inward and outward. At the same time, the electric push rod 701 cyclically pushes the scraper 7 out of the fixture 103, so as to blow the mixture of debris and waste liquid onto the hollow inclined plate 4.

[0041] The bottom of the hollow inclined plate 4 is driven by the differential hydraulic cylinder 403 to move the lifting plate 402 vertically. The lifting plate 402 is driven by the hinge rod 401 to rotate the hollow inclined plate 4 in an arc at the bottom of the liquid baffle 406, which accelerates the downward flow of the waste debris and waste liquid mixture at the top. At the same time, the internal holes can filter the waste liquid and the debris enters the first chip groove 3 at the bottom.

[0042] The second motor 302 drives the chip removal spiral cutter 301 to push the waste chips forward and into the second chip removal groove 5. The chips are received by the moving chip removal chain plate 501 and carried out of the machining center housing 1 from the second chip removal groove 5, thus realizing chip removal. The chip removal chain plate 501 is driven by the third motor 502 at one end to rotate the gear. The gear drives the chain belt to move, and the chain belt drives the chip removal chain plate 501 to move and transmit.

[0043] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.
