Description

Technical Field

[0001] This invention belongs to the field of machine tool and tool magazine installation technology, specifically a tool magazine structure for a disc-type drilling and milling machine. Background Technology

[0002] With the development of CNC machine tool technology, more and more CNC machine tools are equipped with automatic tool changers. Using automatic tool changers can greatly improve the machining efficiency of CNC machine tools. However, the current disc-type tool magazine also has certain limitations. For example, the Chinese invention patent with announcement number CN201520268967.8 uses a disc-type tool magazine in conjunction with a robot arm for tool changing. Although the tool changing speed is relatively fast, it is bulky, expensive, complex in structure, and has a high failure rate. In multi-station machining, due to the large size of the existing disc-type tool magazine, when one station changes tools, the other stations also need to stop machining, which greatly reduces work efficiency and increases the machining cycle. Therefore, we propose a disc-type drilling and milling machine tool magazine structure. Summary of the Invention

[0003] In view of the above situation and to overcome the defects of the prior art, the present invention provides a disc-type drilling and milling machine tool magazine structure, which effectively solves the above problems.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a disc-type drilling and milling machine tool magazine structure, including a turntable bracket, a tool magazine support device installed on the lower side of the turntable bracket, an adjustable tool magazine connected to the lower side of the turntable bracket, an internal gear ring connected to the lower side of the adjustable tool magazine, multiple sets of tool magazine positioning devices installed on the upper side of the adjustable tool magazine, a motor installed on the lower side of the turntable bracket, a gear connected to the transmission end of the motor, and the gear connected to the internal gear ring.

[0005] Preferably, the tool magazine support device includes a tool magazine support shaft, and a support shaft seat and a needle roller bearing are connected to the outside of the tool magazine support shaft.

[0006] Preferably, the tool magazine positioning device includes a joint pin and multiple sets of bolts. The joint pin is fixed to the upper side of the tool magazine by the bolts, and a tool magazine positioning key is connected to the outer side of the joint pin.

[0007] Preferably, the tool magazine positioning device further includes a limiting spring plate, which is fixed to the upper side of the adjusting tool magazine by bolts.

[0008] Preferably, the outer side of the needle roller flat bearing is provided with a tool magazine support sleeve and a retaining ring.

[0009] Preferably, a hollow screw is connected to the lower side of the tool magazine support shaft, an adjusting nut is connected to the outer side of the hollow screw, and a nut washer is connected to the upper side of the adjusting nut.

[0010] Compared with the prior art, the beneficial effects of the present invention are: 1. Low cost: The tool magazine structure of this disc milling machine eliminates the complex robotic arm device. The robotic arm is not only difficult to manufacture and assemble, but its parts are also expensive. This invention reduces the use of expensive parts by using a simple combination of turntable bracket, tool magazine support shaft, tool magazine support shaft seat, etc., thereby effectively reducing the overall manufacturing cost. 2. Simple structure: The number of components in the entire tool magazine structure is relatively small, and the connection between each component is clear and straightforward. This simple and direct installation method makes the equipment assembly process more convenient, and also reduces the probability of failure caused by complex structure. In later maintenance and repair work, maintenance personnel can more easily identify and replace damaged parts, improving the maintainability of the equipment. 3. Quick and convenient tool changing: The tool magazine is supported by four evenly distributed circumferential tool magazine support rollers. This support method makes the rotation of the tool magazine more stable and flexible. During the tool changing process, the tool magazine can quickly and accurately rotate to the designated position, reducing the tool changing time. At the same time, the tool magazine positioning key and limit spring plate ensure the positioning accuracy and stability of the tool during the tool changing process. The design of the internal gear ring rack provides a reliable power transmission method for the tool magazine drive, further improving the efficiency and accuracy of tool changing. 4. High processing efficiency: In multi-station processing scenarios, due to the relatively compact structure of the tool magazine of this invention, when one station is changing tools, it will not have a significant impact on the processing of other stations. Unlike the existing bulky disc-type tool magazines, this tool magazine will not stop processing at other stations because of tool changing at one station, thereby avoiding the waste of processing time, greatly improving the overall work efficiency, shortening the processing cycle, and better meeting the needs of large-scale production of enterprises. 5. High Precision: The adjusting nut is mounted on the hollow screw and used to adjust the axial precision of the tool magazine. The tool magazine support shaft adopts an eccentric design to adjust the radial precision of the tool magazine. These designs allow for convenient fine-tuning of the tool magazine's precision during use, based on actual machining needs and equipment operating conditions. This effectively compensates for axial and radial errors caused by long-term use or external factors, ensuring the accuracy of tool positioning and clamping, thereby improving the quality of machined products.
