Description

Technical Field

[0001] This utility model relates to the field of CNC machine tools, specifically a CNC machine tool with a tool magazine cover. Background Technology

[0002] CNC machine tools are short for numerical control machine tools. They 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, input them to the CNC device through an information carrier, and after calculation and processing, the CNC device sends out various control signals to control the machine tool's movements, automatically machining parts according to the shape and size required by the drawings.

[0003] Currently, a common type of CNC machine tool on the market is one with a tool magazine cover. This cover is typically designed to protect the tool magazine. When changing tools, the cover automatically opens to allow for tool replacement, effectively protecting the tool magazine.

[0004] However, there are some problems with the CNC machine tools with tool magazine covers that are commonly found on the market. The cover is folded and moved by the movement of the tool head to achieve protection. After a long period of operation, metal shavings will adhere to the outer wall of the cover due to static electricity. This may cause the cover to get stuck during the folding process and become unable to move, which will damage the cover and affect work efficiency. Therefore, further improvements are needed. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a CNC machine tool with a tool magazine cover to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A CNC machine tool with a tool magazine cover, comprising a machine tool body, a cover, and a slide column. A slider is slidably mounted on the bottom outer wall of the machine tool body, and an mounting block is fixedly mounted on the end of the slider.

A telescopic rod is fixedly mounted on the top outer wall of the mounting block, and a rotating shaft is rotatably mounted on the end of the telescopic rod. A cleaning roller is fixedly mounted on the outer wall of the rotating shaft. A limit block is fixedly mounted on the outer wall of the end of the telescopic rod, and a spring is sleeved on the outer wall of the telescopic rod. A collection cover is rotatably mounted on the rotating shaft, and a baffle is fixedly mounted on the outer wall of the collection cover. A rack is slidably mounted on the outer wall of the machine tool body, and a gear fixedly mounted on the rotating shaft is meshed on the outer wall of the rack.

[0007] By adopting the above technical solutions, the problem of metal debris adhering to the tool magazine cover during CNC machine tool operation can be effectively solved. The cleaning roller can promptly clean the metal debris on the outer wall of the cover during the movement of the tool head, ensuring smooth sliding and folding of the cover and preventing the cover from getting stuck or damaged due to debris accumulation. This reduces the number of equipment maintenance and costs, extends the service life of the cover, ensures the continuity of CNC machine tool operation, and improves overall work efficiency. The collection cover can collect and discharge the cleaned metal debris to the bottom of the machine tool, preventing the debris from being thrown out by the cleaning roller and re-adhering to the cover, further improving the stability and reliability of machine tool operation. Through the synergistic action of the telescopic rod, spring, and other structures, the cleaning roller can maintain good following and cleaning effect during the movement of the tool head in different directions, further optimizing the performance of the entire protection and cleaning system.

[0008] Furthermore, the slider has a T-shaped cross-section, and two sets of sliders are symmetrically arranged on the outer wall of the bottom of the machine tool body, with the outer wall of the slider fitting against the outer wall of the bottom end of the slide column.

This ensures that the cleaning roller maintains good following performance and cleaning effect during the movement of the cutter head in different directions, thus ensuring the stability of the device.

[0010] Furthermore, two sets of telescopic rods and sliders are symmetrically arranged, and the length of the telescopic rods is less than the sliding range of the protective cover.

[0011] By adopting the above technical solution, the telescopic rod drives the cleaning roller to clean the surface of the protective cover to the maximum extent, without hindering the operation of the cutter head.

[0012] Furthermore, the cleaning roller is located between the two sets of telescopic rods, and the length of the cleaning roller is set to correspond to the width of the protective cover, and the outer wall of the cleaning roller is in contact with the outer wall of the protective cover.

[0013] By adopting the above technical solution, the problem of tool magazine guard failure caused by metal debris adhesion can be effectively solved during the operation of CNC machine tools. The cleaning roller can clean the metal debris on the outer wall of the guard in time during the movement of the tool head, ensuring the smooth sliding and folding of the guard, and avoiding the situation where the guard gets stuck or damaged due to debris accumulation.

[0014] Furthermore, one end of the spring is in contact with the outer wall of the limiting block, and the other end of the spring is in contact with the outer wall of the mounting block.

[0015] By adopting the above technical solution, the spring automatically resets the telescopic rod when it is not compressed.

[0016] Furthermore, the outer wall of the collection cover fits into the outer wall of the protective cover, and the bottom opening of the protective cover is designed with a slope, and the outer wall of the collection cover that fits into the protective cover is designed with an opening.

[0017] By adopting the above technical solution, the collection hood can collect and discharge the cleaned metal debris to the bottom of the machine tool, preventing the debris from being thrown out by the cleaning roller and re-attaching to the hood, thus further improving the stability and reliability of the machine tool operation.

[0018] Furthermore, the outer wall of the rack is fixedly connected to the outer wall of the machine tool body cutter head, and the length of the rack is designed to correspond to the gear. In addition, two sets of racks are symmetrically arranged on the outer wall of the slide column.

[0019] By adopting the above technical solution, the problem of tool magazine guard failure caused by metal debris adhesion can be effectively solved during the operation of CNC machine tools. The cleaning roller can clean the metal debris on the outer wall of the guard in time during the movement of the tool head, ensuring the smooth sliding and folding of the guard, and avoiding the situation where the guard gets stuck or damaged due to debris accumulation.

[0020] In summary, the present invention has the following main advantages:

[0021] This invention, by incorporating a sliding groove, telescopic rod, limit block, spring, mounting block, slider, rotating shaft, cleaning roller, gear, rack, collection cover, and baffle, effectively solves the problem of metal debris adhering to the tool magazine cover during CNC machine tool operation. The cleaning roller promptly removes metal debris from the outer wall of the cover as the tool head moves, ensuring smooth sliding and folding of the cover and preventing it from jamming or becoming damaged due to debris accumulation.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The embodiments of this utility model will be described below based on its overall structure.

[0031] A CNC machine tool with a tool magazine cover, such as Figure 1 - Figure 6As shown, the system includes a machine tool body 1, a protective cover 2, and a sliding column 201. A slider 401 is slidably mounted on the bottom outer wall of the machine tool body 1, and a mounting block 4 is fixedly mounted on the end of the slider 401. A groove 101 corresponding to the slider 401 is opened at the bottom of the machine tool body 1. A telescopic rod 3 is fixedly mounted on the top outer wall of the mounting block 4, and a rotating shaft 5 is rotatably mounted on the end of the telescopic rod 3. A cleaning roller 6 is fixedly mounted on the outer wall of the rotating shaft 5. A limit block 301 is fixedly mounted on the outer wall of the end of the telescopic rod 3, and a spring 302 is sleeved on the outer wall of the telescopic rod 3, so that the cleaning roller 6 can maintain good following and cleaning effect during the movement of the cutter head in different directions, further optimizing the performance of the entire protection and cleaning system. A collection cover 9 is rotatably mounted on the rotating shaft 5, and a baffle 901 is fixedly mounted on the outer wall of the collection cover 9. The collection cover 9 can... The cleaned metal shavings are collected and discharged to the bottom of the machine tool to prevent them from being thrown out again by the cleaning roller 6 and re-adhering to the guard 2. This further improves the stability and reliability of the machine tool operation. A rack 8 is slidably installed on the outer wall of the machine tool body 1, and a gear 7 fixedly installed on the rotating shaft 5 is meshed with the outer wall of the rack 8. This effectively solves the problem of metal shavings adhering to the tool magazine guard 2 during the operation of the CNC machine tool. The cleaning roller 6 can clean the metal shavings on the outer wall of the guard 2 in time during the movement of the tool head, ensuring the smooth sliding and folding of the guard 2. It avoids the situation where the guard 2 is stuck or damaged due to the accumulation of shavings, thereby reducing the number of equipment maintenance and costs, extending the service life of the guard 2, ensuring the continuity of CNC machine tool operation, and improving the overall work efficiency.

[0032] Please see Figure 2 - Figure 5 The slider 401 has a T-shaped cross-section and two sets of sliders 401 are symmetrically arranged on the bottom outer wall of the machine tool body 1. The outer wall of the slider 401 is in contact with the bottom outer wall of the slide column 201, so that the movement of the cutter head drives the slide column 201 to move, thereby causing the slider 401 to drive the cleaning roller 6 to move accordingly. This ensures that the cleaning roller 6 can maintain good following and cleaning effect during the movement of the cutter head in different directions, thus ensuring the stability of the device.

[0033] Please see Figure 1 - Figure 5 Two sets of telescopic rods 3 and sliders 401 are symmetrically arranged, and the length of telescopic rods 3 is less than the sliding range of the cover 2, so that the telescopic rods 3 drive the cleaning rollers 6 to clean the surface of the cover 2 to the maximum extent, without hindering the operation of the cutter head.

[0034] Please see Figure 1 - Figure 5The cleaning roller 6 is located between the two sets of telescopic rods 3, and the length of the cleaning roller 6 corresponds to the width of the guard 2. The outer wall of the cleaning roller 6 is in contact with the outer wall of the guard 2, which can effectively solve the problem of metal debris adhering to the tool magazine guard 2 during the operation of the CNC machine tool. The cleaning roller 6 can clean the metal debris on the outer wall of the guard 2 in time during the movement of the tool head, ensuring the smooth sliding and folding of the guard 2, and avoiding the situation where the guard 2 is stuck and cannot move or is damaged due to the accumulation of debris.

[0035] Please see Figure 1 - Figure 5 One end of the spring 302 is in contact with the outer wall of the limiting block 301, and the other end of the spring 302 is in contact with the outer wall of the mounting block 4, so that the spring 302 automatically resets the telescopic rod 3 when it is not squeezed.

[0036] Please see Figure 1 - Figure 6 The outer wall of the collecting cover 9 is in contact with the outer wall of the protective cover 2, and the bottom opening of the protective cover 2 is designed with a slope. The outer wall of the collecting cover 9 is also designed with an opening on one side, so that the collecting cover 9 can collect the cleaned metal debris and discharge it to the bottom of the machine tool. This prevents the debris from being thrown out again by the cleaning roller 6 and re-attaching to the protective cover 2, further improving the stability and reliability of the machine tool operation.

[0037] Please see Figure 1 and Figure 2 The outer wall of the rack 8 is fixedly connected to the outer wall of the cutter head of the machine tool body 1, and the length of the rack 8 is designed to correspond to the gear 7. Furthermore, two sets of racks 8 are symmetrically arranged on the outer wall of the slide column 201, which can effectively solve the problem of metal debris adhering to the tool magazine cover 2 during the operation of the CNC machine tool. The cleaning roller 6 can clean the metal debris on the outer wall of the cover 2 in time during the movement of the cutter head, ensuring the smooth sliding and folding of the cover 2, and avoiding the situation where the cover 2 is stuck and cannot move or is damaged due to the accumulation of debris.

[0038] The working principle of this invention is as follows: During tool changing, the tool head of the machine tool body 1 moves upward. This movement causes the rack 8 to slide upward, which in turn causes the gear 7 to roll, causing the rotating shaft 5 to rotate. Ultimately, this drives the cleaning roller 6 to rotate, cleaning the metal debris on the outer wall of the protective cover 2. At this time, the metal debris swept off by the cleaning roller 6 is swept into the collection cover 9 and discharged to the bottom of the machine tool from the bottom opening of the collection cover 9. This effectively prevents the metal debris from being thrown out again by the cleaning roller 6. Afterwards, the protective cover 2 opens automatically, allowing for blade replacement. When the blade head moves down to contact the top of the collection cover 9, the telescopic rod 3 is compressed and retracts. At the same time, the rack 8 drives the cleaning roller 6 to continuously clean debris. When the blade head leaves the collection cover 9, the compression force on the telescopic rod 3 is released, and it resets under the action of the spring 302. When the blade head moves left and right, the sliding columns 201 on both sides of the protective cover 2 will press the bottom slider 401, causing the slider 401 to slide, thereby ensuring that the cleaning roller 6 always follows the movement of the blade head, thus ensuring a good cleaning effect.
