Description

Technical Field

[0001] This invention relates to the field of CNC machine tool technology, specifically to a vertical machine tool with a double tool magazine. Background Technology

[0002] The dual-tool magazine vertical machining center is a highly efficient CNC machining equipment. It features two tool magazines that significantly improve production efficiency. This type of machine tool is usually equipped with an advanced control system that enables high-precision machining and has a high degree of automation, including automatic tool changing, which reduces the need for manual operation. The dual-tool magazine vertical machining center is suitable for mass production and can complete more machining tasks in a smaller footprint. It is suitable for applications in the automotive, mechanical engineering, and aerospace industries.

[0003] To improve efficiency in workpiece machining, machine tools need to operate continuously to cut the workpiece. During machining, a large amount of high-temperature iron filings are generated, which accumulate around the worktable, affecting the operator's observation and reducing the cleanliness of the machining process. Moreover, the recovery of iron filings is particularly troublesome. Manual recovery requires stopping the machine tool for safety reasons, and there is also a risk of injury to the operator when manually cleaning the high-temperature iron filings. This seriously reduces safety and machining efficiency. Furthermore, during tool changing, cutting fluid is sprayed onto the surface of the tools in the tool magazine, and a large amount of cutting fluid adheres to the surface of the replaced tools. The cutting fluid adhering to the tool surface for a long time will accelerate the aging of the tools and seriously reduce the service life of the tools in the tool magazine.

[0004] Combining the above issues, we find that existing vertical machine tools with dual tool magazines are difficult to avoid the problems mentioned above when in use. Even if they can be solved, they require the use of external tools, which makes it impossible to achieve the desired effect. Therefore, we propose a vertical machine tool with dual tool magazines.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 The present invention provides a technical solution: a vertical machine tool with a double tool magazine, including a machining mechanism 1, the machining mechanism 1 including a housing 11, a machine tool worktable 12 slidably connected inside the housing 11, two tool magazines 13 fixedly connected to the inner wall of the housing 11, a spindle 14 slidably connected inside the housing 11, a tool holder 15 fixedly connected to the bottom surface of the spindle 14, a flexible moving component 16 fixedly connected to the inner wall of each of the two tool magazines 13, a robot arm 17 fixedly connected to the bottom end of the flexible moving component 16, and a retrieval mechanism 2 provided inside the housing 11; The recycling mechanism 2 includes a cleaning unit 21 located inside the housing 11. The cleaning unit 21 is used to clean the iron filings on the surface of the machine tool worktable 12 and inside the housing 11.

[0022] As a further definition of the cleaning unit 21 of the present invention, the cleaning unit 21 includes an air intake square tube 2101, which is fixedly connected to the inner wall of the outer shell 11. A filter box 2102 is fixedly connected to the back of the air intake square tube 2101. The front of the filter box 2102 is fixedly connected to the back of the outer shell 11. A powerful air duct 2103 is fixedly connected to the inner wall of the outer shell 11. An air pump 2104 is fixedly connected to the bottom surface of the filter box 2102. The air outlet of the air pump 2104 is fixedly connected to the back of the powerful air duct 2103. A filter plate 2105 is snapped into the inside of the filter box 2102. An auxiliary block 2106 is fixedly connected to the inner wall of the outer shell 11. A bidirectional threaded rod 2107 is rotatably connected inside the auxiliary block 2106. A servo motor 2108 is fixedly connected to the right end of the bidirectional threaded rod 2107. Two scrapers 21 are threadedly connected to the outer surface of the bidirectional threaded rod 2107. 09. Both scrapers 2109 are slidably connected to the inside of the auxiliary block 2106. The bottom surfaces of both scrapers 2109 are in contact with the inner bottom wall of the outer shell 11. The inner bottom wall of the outer shell 11 has two sets of through holes 2110. By setting the cleaning unit 21, the air inside the outer shell 11 can be continuously extracted, thereby simultaneously extracting the dust floating in the air and filtering the air mixed with dust. The filtered air is then blown back into the outer shell 11. The flowing air blows the iron filings accumulated on the surface of the machine tool worktable 12 to the inner bottom wall of the outer shell 11, and then pushes the iron filings and pushes them to the outside of the outer shell 11. This achieves the ability to clean the high-temperature iron filings generated when the workpiece is being cut while the machine tool is running continuously. This solves the problem of iron filings accumulating around the worktable and affecting the operator's observation, reducing the cleanliness problem during processing. It is very convenient to clean the iron filings without stopping the machine tool. Please see Figure 4 An auxiliary bearing 2111 is fitted on the outer surface of the bidirectional threaded rod 2107. The auxiliary bearing 2111 is embedded inside the auxiliary block 2106. The auxiliary bearing 2111 can effectively reduce the friction generated by the bidirectional threaded rod 2107 when rotating, making the bidirectional threaded rod 2107 more sensitive when rotating. At the same time, it can also reduce the wear rate of the bidirectional threaded rod 2107 and improve the service life of the bidirectional threaded rod 2107. Please see Figure 1 The front of the outer casing 11 has two slidably connected sealing doors 2112. Each sealing door 2112 has an auxiliary handle 2113 fixedly connected to its front. The sealing doors 2112 can improve the sealing effect of the outer casing 11, improve safety when processing workpieces, and prevent debris from flying out of the outer casing 11 and causing injury to the operator. At the same time, the auxiliary handles 2113 can increase the ease of pulling the sealing doors 2112, thus increasing the convenience of the device.

[0023] The specific implementation method of this embodiment is as follows: First, the machine tool worktable 12, spindle 14, tool holder 15, air pump 2104 and servo motor 2108 are powered on. The workpiece to be processed is clamped by the machine tool worktable 12, and the position of the workpiece and the height of the tool are changed by the machine tool worktable 12 and the spindle 14 respectively, so as to process the workpiece on the surface of the machine tool worktable 12. During the processing of the workpiece, a large amount of high-temperature iron filings and dust will be generated. At this time, the air pump 2104 is started. The air pump 2104 and the suction square tube 2101 are used to extract the air inside the outer shell 11, and at the same time, the dust floating in the air is sucked into the filter box 2102. Then, the dust in the air is filtered by the filter plate 2105, so that the dust is left in the filter box 2102. The filtered air is then transmitted to the powerful air duct 2103 by the air pump 2104. Then, the powerful air blower 2103 blows the iron filings onto the surface of the machine tool worktable 12, thereby blowing the accumulated iron filings onto the bottom of the housing 11. At this time, the servo motor 2108 is started, and the power generated by the servo motor 2108 drives the bidirectional threaded rod 2107 to rotate in both directions alternately. The auxiliary bearing 2111 can increase the sensitivity of the bidirectional threaded rod 2107 when rotating, thereby causing the scraper 2109 to move back and forth in the auxiliary block 2106. During the movement of the scraper 2109, it can push the iron filings falling from the bottom wall of the housing 11 to move, and make the debris be discharged from the housing 11 through the through hole 2110. This achieves the ability to clean the iron filings inside the housing 11, avoiding the need to stop the machine tool when cleaning manually. It can also prevent the excessive iron filings from affecting the operator's observation, improve the cleanliness of the processing process, and effectively improve the processing efficiency during use.

[0024] Example 2: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 The present invention provides a technical solution: a vertical machine tool with a double tool magazine. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The recycling mechanism 2 also includes a collection and cooling unit 22, which is located below the outer shell 11. The collection and cooling unit 22 is used to convey the cleaned iron filings and cool the iron filings during the conveying process.

[0025] As a further definition of the cooling collection unit 22 of the present invention, the cooling collection unit 22 includes a fixing block 2201. The upper surface of the fixing block 2201 is fixedly connected to the bottom surface of the outer shell 11. A water storage tank 2202 is fixedly connected to the upper surface of the fixing block 2201. A one-way valve 2203 is fixedly connected to the upper surface of the water storage tank 2202. An auxiliary water pump 2204 is fixedly connected to the inner bottom wall of the water storage tank 2202. A spray pipe 2205 is fixedly connected to the inner wall of the fixing block 2201. The outlet end of the auxiliary water pump 2204 passes through the water storage tank 2202, the outer shell 11, and the fixing block 2201 in sequence and is fixedly connected to the upper surface of the spray pipe 2205. The fixing block 2201... The inner wall is rotatably connected to two rotating rods 2206. The outer surfaces of the two rotating rods 2206 are fixedly connected to a conveyor belt 2207. The upper surface of the fixed block 2201 is provided with two sets of material leakage grooves 2208. By setting up a collection and cooling unit 22, the iron filings pushed out of the outer shell 11 can be transported to a designated area, thereby improving the convenience of subsequent iron filings recycling. At the same time, the iron filings can be cooled during the transportation process to prevent operators from being injured by excessively high iron filings during recycling. This solves the problem that manually cleaning high-temperature iron filings will injure operators, effectively improving safety and processing efficiency during use. Please see Figure 3 A drain pipe 2209 is fixedly connected to the right side of the water storage tank 2202. A switch valve 2210 is fixedly connected to the outer surface of the drain pipe 2209. The drain pipe 2209 improves the convenience of draining the water in the water storage tank 2202 and prevents the water inside the water storage tank 2202 from deteriorating when it is not used for a long time. At the same time, the switch valve 2210 can control the closing of the drain pipe 2209. Please see Figure 6 The bottom surface of the fixed block 2201 is fixedly connected to two sets of support blocks 2211. The outer surfaces of the two sets of support blocks 2211 are fixedly connected to anti-slip rubber blocks 2212. The support blocks 2211 can support the area of ​​the fixed block 2201 and improve the stability during use. At the same time, the anti-slip rubber blocks 2212 can increase the contact area between the support blocks 2211 and the ground, further improving the stability when supporting the fixed block 2201.

[0026] The specific implementation method of this embodiment is as follows: First, the auxiliary water pump 2204 and the conveyor belt 2207 are connected to the power supply, and cooling water is added to the water storage tank 2202 through the one-way valve 2203. Then, the iron filings discharged from the outer shell 11 are guided by the material leakage chute 2208 and fall onto the upper surface of the conveyor belt 2207. At this time, the conveyor belt 2207 is started, and the iron filings are discharged to the outside of the outer shell 11 by the conveyor belt 2207. At the same time, the auxiliary water pump 2204 is started, and the suction generated by the auxiliary water pump 2204 is used to continuously draw water from the water storage tank 2202 and transfer the water to the nozzle 2205. Water is evenly sprayed onto the surface of the conveyor belt 2207 by the nozzle 2205, thereby cooling the high-temperature iron filings on the surface of the conveyor belt 2207. This prevents operators from being injured when handling the iron filings and improves the safety of subsequent iron filings recycling. When not in use for a long time, the switch valve 2210 is turned to open the drain pipe 2209, and the water in the water storage tank 2202 is drained through the drain pipe 2209. This achieves automatic transportation of iron filings without the need for manual operation, and also cools the high-temperature iron filings, effectively improving the safety of recycling.

[0027] Example 3: Please refer to Figure 1 , Figure 6 , Figure 7 and Figure 8 The present invention provides a technical solution: a vertical machine tool with a double tool magazine. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The tool magazine 13 is provided with a protective mechanism 3 inside. The protective mechanism 3 is used to protect the tool when it is replaced and to dehumidify it after the tool is replaced.

[0028] As a further definition of the protective mechanism 3 of the present invention, the protective mechanism 3 includes two movable blocks 301, both of which are slidably connected to the inside of the tool magazine 13. A tool storage rack 302 is rotatably connected inside each of the two movable blocks 301. A hydraulic rod 303 is fixedly connected to the upper surface of each of the two movable blocks 301. A tool changing slot 304 is provided on the bottom surface of each of the two tool magazines 13. An air box 305 is provided above both tool magazines 13. Conveyor air ducts 306 are fixedly connected to the left and right sides of the air box 305. Guide air ducts 307 are fixedly connected to the bottom surface of each of the two conveyor air ducts 306. An annular air outlet duct 3 is fixedly connected to the inner wall of each of the two tool magazines 13. 08. The bottom ends of the two guide air ducts 307 are fixedly connected to the outer surface of the annular air outlet duct 308. The inner walls of the two conveying air ducts 306 are fixedly connected with heating wires 309. By setting the protective mechanism 3, a single designated tool can be accurately removed and replaced by the cooperation of the flexible moving component 16 and the robot arm 17. This avoids the situation where cutting fluid is sprayed onto the tool surface in the tool magazine 13 during the tool replacement process, which would accelerate the aging of the tool. At the same time, the residual cutting fluid on the tool surface can be treated after replacement to prevent the cutting fluid from adhering to the tool surface for a long time and causing damage to the tool. This effectively improves the service life of the tools in the tool magazine 13. Please see Figure 6 Two sets of stabilizing columns 310 are fixedly connected to the bottom surface of the bellows 305. The bottom ends of the two sets of stabilizing columns 310 are fixedly connected to the upper surface of the tool magazine 13. The stabilizing columns 310 can provide a good support position for the bellows 305, increase the stability of the bellows 305 during operation, and prevent the bellows 305 from shaking during operation, thus effectively improving the stability of the device during use. Please see Figure 7 Each of the two moving blocks 301 has a stabilizing block 311 fixedly connected to one of their opposite sides. Both stabilizing blocks 311 are slidably connected inside the tool magazine 13. The stabilizing blocks 311 can move simultaneously with the moving blocks 301 and increase the stability of the moving blocks 301 by generating friction against the tool magazine 13 during the movement. They can also limit the movement distance of the moving blocks 301.

[0029] The specific implementation of this embodiment is as follows: First, the hydraulic rod 303, bellows 305, heating wire 309, and flexible moving assembly 16 are powered on. The flexible moving assembly 16 consists of an electric telescopic rod and a rotary motor. When a tool needs to be replaced, the tool holder 302 and the moving block 301 are rotated by their rotational connection, making the designated tool perpendicular to the tool changing slot 304. Then, the hydraulic rod 303 is activated, which drives the moving block 301 to move downward. The stabilizing block 311 can limit the movement distance of the moving block 301, thereby causing the tool holder 302 to move downward simultaneously and the tool to be removed from the tool changing slot 304. At this time, the flexible moving assembly 16 is activated, and the rotary motor in the flexible moving assembly 16 drives the robot arm 17 to rotate and clamp the tool to be replaced and the tool to be replaced. Then, the electric telescopic rod drives the robot arm 17 to descend, thereby removing the two tools from the tool holder 302 and the tool holder 15 respectively. The tool is removed and then rotated 180 degrees by a rotary motor to change the position of the two tools. Then it is raised and the two tools are respectively locked in the tool holder 15 and the tool storage rack 302. This allows only the required tool to be removed when changing tools, avoiding the spraying of cutting fluid onto the surface of the tools in the tool magazine 13 during the replacement process, effectively increasing the service life of the tools in the tool magazine 13. At the same time, a large amount of cutting fluid will remain on the surface of the removed tool. At this time, the air box 305 is activated, and the air flow generated by the air box 305 is transmitted to the annular air outlet 308 by the air conveying duct 306 and the air guide duct 307. At the same time, the heating wire 309 can heat the air flow, and then blow the hot air into the tool magazine 13 through the annular air outlet duct 308, thereby drying the cutting fluid adhering to the surface of the tools in the tool magazine 13, preventing the cutting fluid from adhering to the tool surface for a long time and causing damage, and effectively reducing the aging rate of the tools.
