Description

Technical Field

[0001] This application relates to the field of machine tool technology, and in particular to a heavy-cutting machine tool for mechanical production and processing of metal. Background Technology

[0002] A machine tool is a device that uses a cutting tool to perform turning operations on a rotating workpiece. It is also called a machine tool or machine workpiece, and is commonly referred to simply as a machine tool. Machine tools are classified into heavy-duty cutting machine tools and fine-duty cutting machine tools according to their machining accuracy. Heavy-duty cutting machine tools are those with lower machining accuracy, suitable for workpieces where high precision is not required. However, during cutting, a significant amount of debris and impurities remain on the cutting tool, and the lubricating oil on the tool is scraped off. The tool needs to be cleaned and maintained after use, and currently, most of these operations are performed manually.

[0003] In existing metal cutting machine tools, such as Chinese Patent No. CN215394107U, a metal cutting machine tool is disclosed. Specifically, it includes a machine tool body and a cleaning device. The cleaning device includes two slide rods, both of which are slidably connected to the interior of a fixed frame. A rotating ring is fixedly connected to the end of each slide rod away from the fixed frame. A limiting ring is rotatably connected to the surface of the rotating ring. Four thin rods are evenly slidably inserted inside the limiting ring. A connecting piece is fixedly connected to the end of each of the four thin rods away from each other. When the thin rods are moved to the position on the workpiece where there are cutting residues, the tapered ring is released. The connecting piece is pulled by the first spring force on the surface of the limiting ring, causing the thin rods to press tightly against the position on the workpiece where there are cutting residues. At this time, rotating the limiting ring on the surface of the rotating ring causes the thin rods to move relative to the surface of the workpiece, thereby achieving the effect of removing the cutting residues from the surface of the workpiece.

[0004] While the aforementioned existing technologies can achieve the effect of cutting workpieces, firstly, they require manual installation or replacement of cutting tools, which may lead to errors during installation or replacement, making the operation complex and hindering work efficiency; secondly, they only clean the chips on the workpiece, not the cutting tool surface, requiring manual cleaning and increasing the labor intensity of workers. Therefore, there is still room for improvement in existing metal cutting machine tools. Summary of the Invention

[0030] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0031] This application discloses a heavy-duty metal cutting machine tool that can automatically clean and maintain the tool without adjusting the position of the tool and workpiece axis.

[0032] Reference Figure 1 and Figure 3 As shown in this embodiment, a heavy-duty metal cutting machine tool for mechanical production includes: a machine tool body 1; a clamping module 2, which is installed on the inner wall of the machine tool body 1, used to clamp the workpiece and drive it to rotate at high speed; a moving module 3, which is installed at the lower end inside the machine tool body 1, and can move arbitrarily in a plane; and a cutting module 4, which is installed at the upper end of the moving module 3, and can freely change tools and cut the workpiece clamped by the clamping module 2. The cutting module 4 includes a rectangular frame 41, a conversion unit 42, an ejection unit 43, and a door panel frame 44. The moving module 3 includes a fixing unit 45, a cleaning unit 46, and an application unit 47. A rectangular frame 41 is installed on the upper end of the moving module 3. A through groove is provided in the middle of the rectangular frame 41, and a conversion unit 42 is installed in the through groove. An ejection unit 43 is symmetrically installed on the lower left side of the through groove. A detachable door panel frame 44 is installed on the right side of the rectangular frame 41. A detachable fixing unit 45 is installed on the upper end of the door panel frame 44. A fan-shaped groove is symmetrically provided on the lower end of the door panel frame 44. A detachable cleaning unit 46 is installed in the fan-shaped groove on the right side of the door panel frame 44, and a detachable application unit 47 is installed in the fan-shaped groove on the left side of the door panel frame 44.

[0033] In actual use, the workpiece is installed in the middle of the clamping module. After the clamping module 2 clamps and fixes the workpiece, it drives the workpiece to rotate. The moving module 3 drives the cutting module 4 to move in the plane. When the workpiece needs to be re-cut, the conversion unit 42 drives the tool to rotate, so that the tool to be used rotates to the top of the through slot. Then, the conversion unit 42 drives the tool to extend out from inside the fixing unit 45. The fixing unit 45 clamps and fixes the tool, and the extended tool can perform re-cutting on the workpiece. After the tool finishes cutting, the fixing unit 45 resets, the conversion unit 42 drives the tool to reset and rotate, and the conversion unit 42 replaces other tools to perform re-cutting on the workpiece.

[0034] The cutting module 4 performs heavy cutting on the workpiece. After use, the cutting tool usually has a lot of residual chips and impurities. The cutting module 4 can be connected to the controller, which is used to mark the used tool and control the extension of the ejection unit 43. When the used tool rotates to the cleaning unit 46, the controller controls the ejection unit 43 to eject the tool to the middle of the cleaning unit 46. The cleaning unit 46 cleans and collects the chips on the tool, and then the tool resets. The conversion unit 42 drives the tool to continue rotating. When the cleaned tool rotates to the coating unit 47, the controller controls the ejection unit 43 to eject the tool to the middle of the coating unit 47. The coating unit 47 sprays maintenance oil onto the tool, and then the tool resets. This realizes the free replacement of tools without adjusting the position of the tool and the workpiece center axis during use, and realizes the function of automatic cleaning and maintenance of tools after use.

[0035] It should be noted that the cutting tool extending from the cutting module 4 is always at the same height as the center of the workpiece held by the clamping module 2, so that the tool can always accurately cut the workpiece after the tool is changed.

[0036] Reference Figure 4 As shown, the conversion unit 42 includes a rotating component 421, a cylindrical frame 422, a cutting component 423, and a moving component 424. The rotating component 421 is installed in the middle of the rectangular frame 41, and the cylindrical frame 422 is installed in the middle of the rotating component 421. Grooves are evenly arranged on the cylindrical frame 422, and the cutting component 423 is installed in the groove. The moving component 424 is installed at the upper end of the through groove, and the moving component 424 cooperates with the cutting component 423.

[0037] In actual use, when the workpiece needs to be heavily cut, the rotating component 421 drives the cylindrical frame 422 to rotate, and the cutting component 423 rotates synchronously with the cylindrical frame 422. When the tool to be used rotates to the top of the through slot, the cutting component 423 engages with the moving component 424. The moving component 424 drives the cutting component 423 to move into the fixed unit 45. The fixed unit 45 clamps and fixes the tool. After the cutting is completed, the fixed unit 45 resets, and the moving component 424 drives the cutting component 423 to reset, thus realizing the free replacement of the tool and the function of heavy cutting of the workpiece.

[0038] Reference Figure 5 As shown, the rotating assembly 421 includes a rotating column 4211 and a drive motor 4212. The rotating column 4211 is mounted on the middle of the rectangular frame 41 via a bearing. The drive motor 4212 is mounted on the left side of the rectangular frame 41 via a motor mount. The output shaft of the drive motor 4212 is connected to the rotating column 4211. A cylindrical frame 422 is mounted on the middle of the rotating column 4211.

[0039] In actual use, when it is necessary to change the tool, the drive motor 4212 drives the rotating column 4211 to rotate, and the cylindrical frame 422 rotates synchronously with the rotating column 4211, so that the tool to be used is rotated to the top of the through slot through the rotating column 4211. At this time, the cutting component 423 just matches the lower end of the moving component 424.

[0040] Reference Figure 5 and Figure 6 As shown, the cutting assembly 423 includes a limiting block 4231, a return spring 4232, a tool holder 4233, a cutting tool 4234, a push rod 4235, a locking block 4236, and a positioning rod 4237. Sliding grooves are symmetrically arranged on both sides of the groove. A limiting block 4231 is slidably arranged within the sliding groove. A return spring 4232 is installed between the limiting block 4231 and the sliding groove. A tool holder 4233 is installed between the limiting blocks 4231. The tool holder 4233 has a U-shaped cross-section. A cutting blade 4234 is installed at the lower right end of the tool holder 4233. A push rod 4235 is installed on the left side of the tool holder 4233. The end of the push rod 4235 is smooth. The push rod 4235 cooperates with the ejection unit 43. A locking block 4236 is installed at the upper end of the tool holder 4233. The locking block 4236 cooperates with the moving component 424. Positioning rods 4237 are evenly installed on the right side of the tool holder 4233. The end of the positioning rod 4237 is tapered. The positioning rod 4237 cooperates with the fixing unit 45.

[0041] In actual use, when the tool to be used rotates to the top of the through slot, the locking block 4236 engages with the moving component 424. The moving component 424 drives the locking block 4236 to move into the fixed unit 45. The cutting tool 4234 moves synchronously with the locking block 4236 through the tool holder 4233. Then, the positioning rod 4237 is accurately inserted into the fixed unit 45, realizing the function of accurately positioning the tool. The fixed unit 45 can also clamp and fix the cutting tool 4234 to prevent the tool from shaking during operation. After the cutting tool 4234 finishes cutting the workpiece, the fixed unit 45 resets, and the moving component 424 drives the cutting tool 4234 to reset.

[0042] Reference Figure 5 As shown, the moving component 424 includes a slide rail 4241, an electric slider 4242, and a U-shaped frame 4243. The slide rail 4241 is installed at the upper end of the through groove, the electric slider 4242 is installed at the lower end of the slide rail 4241, and the U-shaped frame 4243 is installed at the lower end of the electric slider 4242. The U-shaped frame 4243 cooperates with the locking block 4236.

[0043] In actual use, when the tool to be used rotates to the top of the through slot, the locking block 4236 rotates into the U-shaped frame 4243, so that the locking block 4236 and the U-shaped frame 4243 are locked together. Then, the electric slider 4242 drives the U-shaped frame 4243 to move towards the fixed unit 45. The locking block 4236 drives the cutting tool 4234 to move synchronously through the tool holder 4233. When the cutting tool 4234 finishes cutting the workpiece, the electric slider 4242 drives the U-shaped frame 4243 to reset. The locking block 4236 drives the cutting tool 4234 to reset synchronously through the tool holder 4233.

[0044] Reference Figure 7 As shown, the ejection unit 43 includes an airbag 431, an arc-shaped plate 432, and a tension spring 433. A mounting groove is symmetrically arranged at the lower left end of the through groove. The mounting groove has an arc-shaped structure. An airbag 431 is installed inside the mounting groove, and an arc-shaped plate 432 is installed outside the airbag 431. The middle part of the arc-shaped plate 432 has a protruding structure, and a tension spring 433 is installed between the end of the arc-shaped plate 432 and the mounting groove.

[0045] In actual use, when the cutting blade 4234 marked by the controller rotates to the cleaning unit 46, the controller controls the airbag 431 to start inflating. The airbag 431 pushes out the arc plate 432, and the tension spring 433 gradually stretches. When the push rod 4235 on the tool holder 4233 contacts the arc plate 432 and moves along the surface of the arc plate 432, the push rod 4235 gradually extends towards the cleaning unit 46. The cutting blade 4234 moves synchronously with the push rod 4235 through the tool holder 4233. At this time, the return spring 4232 gradually stretches. When the cutting blade 4234 extends to the middle of the cleaning unit 46, the cleaning unit 46 cleans the cutting blade 4234. After cleaning, the controller controls the air in the airbag 431 to be discharged, and the tension spring 433 drives the arc plate 432 to return to its original position. The return spring 4232 drives the tool holder 4233 to return to its original position through the limit block 4231.

[0046] When the cutting blade 4234 marked by the controller rotates to the coating unit 47, the controller controls the airbag 431 to start inflating. The airbag 431 pushes out the arc plate 432, and the tension spring 433 gradually stretches. When the push rod 4235 on the tool holder 4233 contacts the arc plate 432 and moves along the surface of the arc plate 432, the push rod 4235 gradually extends towards the cleaning unit 46. The cutting blade 4234 moves synchronously with the push rod 4235 through the tool holder 4233. At this time, the return spring 4232 gradually stretches. When the cutting blade 4234 extends to the middle of the coating unit 47, the coating unit 47 applies maintenance oil to the cutting blade 4234. Afterward, the controller controls the air in the airbag 431 to be discharged, and the tension spring 433 drives the arc plate 432 to return to its original position. The return spring 4232 drives the tool holder 4233 to return to its original position through the limit block 4231.

[0047] Reference Figure 6 As shown, the fixing unit 45 includes a fixing frame 451, a plug-in frame 452, a cylinder 453, and a clamping frame 454. The upper end of the door panel frame 44 is provided with a rectangular groove, and the fixing frame 451 is installed in the rectangular groove by bolts. The fixing frame 451 is provided with a blade outlet in the middle, and a U-shaped groove is provided on the inner side of the blade outlet. The plug-in frame 452 is installed in the U-shaped groove. Plug-in holes are evenly provided on the inner side of the plug-in frame 452. The plug-in holes cooperate with the conversion unit 42. A clamping groove is provided on the outer side of the blade outlet, and cylinders 453 are symmetrically installed in the clamping groove. The top of the cylinder 453 is installed with a clamping frame 454 through a flange. The clamping frame 454 has a U-shaped structure.

[0048] In actual use, when the electric slider 4242 drives the locking block 4236 to move towards the exit end of the tool through the U-shaped frame 4243, the tool holder 4233 moves synchronously with the locking block 4236. The positioning rod 4237 can be accurately inserted into the insertion hole to position the cutting tool 4234. Then, the cutting tool 4234 extends from the exit end, and the cylinder 453 pushes the clamping frame 454 to clamp and fix the cutting tool 4234, thus realizing the function of clamping and fixing the cutting tool 4234. This allows the cutting tool 4234 to accurately perform heavy cutting on the workpiece and process the workpiece into a finished product.

[0049] Reference Figure 8 As shown, the cleaning unit 46 includes a fan-shaped plate 461, a spray plate 462, and a collection rack 463. The fan-shaped plate 461 is installed in the fan-shaped groove on the right side of the door panel frame 44. The spray plate 462 is installed at the upper end of the fan-shaped plate 461. Spray holes are evenly arranged on the spray plate 462. The collection rack 463 is installed at the lower end of the fan-shaped plate 461.

[0050] In actual use, the spray plate 462 is connected to the air pump, and the air in the air pump flows out through the spray hole. When the cutting blade 4234 moves to the middle of the fan-shaped plate 461, the spray plate 462 sprays high-pressure air to clean the cutting blade 4234, and the debris on the cutting blade 4234 falls into the collection rack 463 below.

[0051] It should be noted that the sector plate 461 can be disassembled periodically to clean the debris in the collection rack 463.

[0052] Reference Figure 8 As shown, the coating unit 47 includes a fan-shaped plate 471, a connecting plate 472, and a spray nozzle 473. The fan-shaped plate 471 is installed in the fan-shaped groove on the left side of the door panel frame 44. The connecting plate 472 is installed inside the fan-shaped plate 471. The spray nozzles 473 are evenly installed on the inner side of the connecting plate 472.

[0053] In actual use, an oil inlet is provided on the outer side of the connecting plate 472, through which the maintenance oil flows to the nozzle 473. When the cutting tool 4234 moves to the middle of the fan-shaped plate 471, the nozzle 473 can spray out the maintenance oil, which can maintain the cutting tool 4234 and prevent problems such as rusting.

[0054] It should be noted that the fan-shaped plate 471 can be disassembled periodically to clean the nozzle 473 and the connecting plate 472, keeping the inside of the fan-shaped plate 471 clean.

[0055] The implementation principle of this embodiment is as follows:

[0056] 1: The rotating extension drives the motor 4212 to rotate the rotating column 4211. The cylindrical frame 422 rotates synchronously with the rotating column 4211, so that the tool to be used is rotated to the top of the through slot through the rotating column 4211. The electric slider 4242 drives the U-shaped frame 4243 to move towards the fixed unit 45. The locking block 4236 drives the cutting tool 4234 to move synchronously through the tool holder 4233.

[0057] 2: Fixed cutting. When the tool holder 4233 moves synchronously with the locking block 4236, the positioning rod 4237 can be accurately inserted into the insertion hole to position the cutting tool 4234. Then, the cutting tool 4234 extends from the exit port, and the cylinder 453 pushes the clamping frame 454 to clamp and fix the cutting tool 4234. The cutting tool 4234 cuts the workpiece. After the cutting is completed, the cutting tool 4234 returns to its original position.

[0058] 3: Cleaning and coating. When the used blade rotates to the cleaning unit 46, the ejection unit 43 ejects the blade to the middle of the cleaning unit 46. The cleaning unit 46 cleans and collects the residue on the blade. After that, the blade is reset, and the conversion unit 42 drives the blade to continue rotating. When the cleaned blade rotates to the coating unit 47, the ejection unit 43 ejects the blade to the middle of the coating unit 47. The coating unit 47 sprays maintenance oil onto the blade. After that, the blade is reset.

[0059] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
