Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, specifically a CNC machine tool for metal processing. Background Technology

[0002] CNC machine tools, short for numerical control machine tools, are automated machine tools equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, and input them into the CNC device via an information carrier. After processing, the CNC device sends out various control signals to control the machine tool's movements, automatically machining parts according to the shape and dimensions required by the drawings.

[0003] According to Chinese Patent CN218696574U, a CNC machine tool for metal processing that facilitates chip collection includes a chip guide plate. During processing, chips fall onto the chip guide plate, and the guide angle of the chip guide plate can be adjusted via control keys to facilitate chip falling. If stubborn chips cannot fall into the chip collection box, the control keys can be used to shake the guide plate to make the chips fall smoothly into the chip collection box. Water generated during processing also flows into the chip collection box and filters the chips through a filter screen into the chip collection box, while wastewater leaks into a wastewater tank for storage and reuse, saving production costs.

[0004] In the above-mentioned device, the filter screen is simply inserted into the debris collection box, which makes it easy for the filter screen to slip out during use. Furthermore, the gap between the filter screen and the debris collection box is too large, causing fallen debris to get stuck in the gap. This not only increases the workload during the next cleaning but also causes fine debris to accumulate during the debris collection process, leading to improper installation of the filter screen. Therefore, a CNC machine tool for metal processing is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a CNC machine tool for metal processing. It features advantages such as preventing filter screen slippage during chip collection, ensuring a tighter fit between the filter screen and the inner wall of the collection box, and reducing the likelihood of subsequent unusability. This solves the problems of filters being simply inserted into the chip collection box, which easily slips out during use. Furthermore, the excessive gap between the filter screen and the chip collection box causes fallen chips to get stuck, increasing the workload during subsequent cleaning and leading to an accumulation of fine chips during collection, ultimately resulting in improper filter screen installation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a CNC machine tool for metal processing, comprising a machine tool body, wherein a water tank is provided inside the machine tool body, and two mounting plates are fixedly connected inside the water tank, and a sealing and protective component is provided between the two mounting plates;

[0007] The sealing and protective assembly includes two first guide plates, both of which are fixedly connected to the outer surfaces of two mounting plates. A protective cover is slidably connected inside each of the two first guide plates. A common collection box is fixedly connected to one side of each of the two protective covers. Two second guide plates are fixedly connected inside the collection box. A common sealing cover is slidably connected to the outer surfaces of the two second guide plates. A filter screen is fixedly connected to the inner wall of the sealing cover. A sealing baffle is fixedly connected to the front of the sealing cover. A limit component is provided on the front of the collection box.

[0008] Furthermore, the limiting component includes a fixing plate, which is fixedly connected to the front of the collection box. A gravity baffle is slidably connected inside the fixing plate, and a limiting block is elastically connected to the front of the collection box.

[0009] Furthermore, the fixing plate is fixedly connected to the front of the collection box, and a sliding through hole is provided inside the fixing plate, through which the gravity baffle slides inside the fixing plate.

[0010] Furthermore, the gravity baffle is T-shaped, with a ring handle fixedly connected to its top, and the limiting block is movably engaged with the ring wrench.

[0011] Furthermore, the cross-sectional shape of the two first guide plates is concave, the cross-sectional shape of the two protective cover plates is convex, guide wheel plates are fixedly connected to opposite sides of the two mounting plates, rollers are fixedly connected to the bottom of the two protective cover plates, and the two rollers are slidably connected to the two guide wheel plates.

[0012] Furthermore, the sealing cover is fitted to the inner wall of the collection box on one side, and an annular sealing gasket is fixedly connected to the back of the sealing baffle, which fits and seals against the front of the collection box.

[0013] Furthermore, two mounting blocks are fixedly connected to the front of the water tank. Each of the two mounting blocks has a limiting rod passing through its interior. Each of the two limiting rods has a limiting block fixedly connected to its opposite side. Nuts are threaded onto the outer surface of each of the two limiting rods.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] This CNC machine tool for metal processing, when the collection box slides into the water tank, the sliding engagement between the rollers at the bottom and the guide rail plate ensures that the collection box is protected after it is moved to the designated position. The sliding engagement between the first guide plate and the protective cover plate further prevents splashed iron filings from scattering out and making the collection box difficult to remove. When the filter screen is in use, it slides between the two second guide plates inside the collection box via the sealing cover. The sealing baffle connected to the front of the sealing cover is blocked by a gravity baffle to prevent it from sliding out. Because the sealing cover fits snugly against the inner wall of the collection box, it achieves a sealing effect, preventing debris from getting stuck due to gaps. The front of the filter screen is then sealed by the annular sealing gasket on the sealing baffle. After adjusting the two limit rods to limit the sealing baffle, the two nuts are rotated for final fixation, thus preventing cooling water leakage during use. Attached Figure Description

Detailed Implementation

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Please see Figures 1 to 3This embodiment of a CNC machine tool for metal processing includes a machine tool body 1. A water tank 2 is provided inside the machine tool body 1. Two mounting plates 3 are fixedly connected inside the water tank 2. A sealing and protective assembly is provided between the two mounting plates 3. The sealing and protective assembly includes two first guide plates 4. The two first guide plates 4 are fixedly connected to the outer surfaces of the two mounting plates 3. A protective cover plate 5 is slidably connected inside the two first guide plates 4. The cross-sectional shape of the two first guide plates 4 is concave, and the cross-sectional shape of the two protective cover plates 5 is convex.

[0022] Guide wheel plates 8 are fixedly connected to the opposite side of the two mounting plates 2, and rollers 7 are fixedly connected to the bottom of the two protective cover plates 5. The two rollers 7 are slidably connected to the two guide wheel plates 8.

[0023] Two protective covers 5 are fixedly connected to the same collection box 6 on opposite sides. Two second guide plates 9 are fixedly connected inside the collection box 6. The same sealing cover 10 is slidably connected to the outer surface of the two second guide plates 9. The side of the sealing cover 10 closest to the inner wall of the collection box 6 is fitted together.

[0024] A filter screen 11 is fixedly connected to the inner wall of the sealing cover 10. A sealing baffle 12 is fixedly connected to the front of the sealing cover 10. An annular sealing gasket is fixedly connected to the back of the sealing baffle 12. The annular sealing gasket fits and seals against the front of the collection box 6. Two mounting blocks 16 are fixedly connected to the front of the water tank 2. A limiting rod 17 is inserted inside each of the two mounting blocks 16. A limiting block is fixedly connected to the opposite side of each of the two limiting rods 17. Nuts are threaded onto the outer surface of each of the two limiting rods 17.

[0025] The front of the collection box 6 is provided with a limiting component, which includes a fixing plate 13. The fixing plate 13 is fixedly connected to the front of the collection box 6. A gravity baffle 14 is slidably connected inside the fixing plate 13. The fixing plate 13 is fixedly connected to the front of the collection box 6. A sliding through hole is opened inside the fixing plate 13. The gravity baffle 14 slides inside the fixing plate 13 through the sliding through hole.

[0026] The front of the collection box 6 is elastically connected to the limiting block 15. The gravity baffle 14 is T-shaped and has a ring handle fixedly connected to its top. The limiting block 15 is movably engaged with the ring wrench.

[0027] In this embodiment, when the sealing baffle 12 is in contact with the front of the collection box 6, the gravity baffle 14 will block the sealing baffle 12 under its own weight. Then, in order to achieve the best sealing effect, the two limiting rods 17 are moved out relative to each other and pressed against each other. Finally, the nut is used to limit the position, thereby preventing the cooling water from leaking out from the front.

[0028] In this embodiment, the filter screen 11 is not connected to the sealing baffle 12, but is fixedly connected to the sealing cover 10 by screws. The sealing cover 10 is U-shaped, so it is convenient and quick to replace and clean the filter screen 11.

[0029] In this embodiment, when the gravity baffle 14 is not blocking, it can be lifted by the ring handle and then locked in place by the limiting block 15 to prevent the front from being blocked during cleaning, thus improving convenience.

[0030] The working principle of the above embodiments is as follows:

[0031] In this CNC machine tool for metal processing, when the collection box 6 slides into the water tank 3, the rollers 7 at the bottom slide against the guide rail 8. After the collection box 6 is moved to the placement position, the first guide plate 4 slides against the protective cover 5 to prevent the iron filings from scattering out and making the collection box 6 difficult to remove. When the filter screen 11 is in use, it can slide between the two second guide plates 9 inside the collection box 6 through the sealing cover 10. The sealing baffle 12 connected to the front of the sealing cover 10 is blocked by the gravity baffle 14 to prevent it from sliding out. Since the sealing cover 10 is in contact with the inner wall of the collection box 6, it can achieve a sealing effect and prevent the debris from getting stuck due to the gap. The front of the filter screen 11 is in contact with the annular sealing gasket on the sealing baffle 12. After adjusting the two limit rods 17 to limit the sealing baffle 12, the two nuts are rotated for final fixation, thereby achieving the purpose of preventing cooling water from leaking out during use.
