Description
Technical Field
[0001] This utility model relates to the field of cutting tools for turning and milling, specifically to a tool structure for a turning and milling composite machine tool. Background Technology
[0002] Milling-turning composite machine tools, as high-efficiency machining equipment that integrates multiple processes such as turning and milling, are widely used in precision machinery manufacturing and other fields. Their machining accuracy and efficiency largely depend on the performance of the tool structure. However, the tool structure of existing milling and turning machines still has some problems in use: First, most of the cutting tools on existing machine tools are designed with a single cutting head, which makes it impossible to quickly change to a cutting head of a suitable shape according to the actual processing needs during milling, thus reducing the flexibility of machine tool tool usage. Secondly, existing tool structures are usually installed on machine tools using only simple bolt connections, which makes the tool prone to loosening during use, thus affecting the stability of the machine tool's tool usage. Utility Model Content
[0003] In order to solve the problems of poor flexibility in the use of existing machine tool cutting tools and insufficient stability in tool installation, the purpose of this utility model is to provide a cutting tool structure for a turning-milling composite machine tool.
[0004] To solve the above technical problems, the present invention adopts the following technical solution: a tool structure for a milling and turning machine tool, including a mounting plate, the mounting plate being fixedly installed on the output end of the machine tool spindle, a docking plate being movably engaged on the lower surface of the mounting plate, a connecting component being provided between the mounting plate and the docking plate, a housing being fixedly connected to the lower surface of the docking plate, a switchable tool assembly being provided inside the housing, the switchable tool assembly including a support plate, the support plate being fixedly installed on the inner wall of the housing, cylinders being fixedly installed in a circular array on the upper surface of the support plate, and the output end of the cylinders penetrating the upper surface of the support plate and being fixedly connected to a first circular plate, a second circular plate being movably engaged on the lower surface of the first circular plate, a connecting bolt being threaded between the first circular plate and the second circular plate, and a tool head body being fixedly installed on the lower surface of the second circular plate.
[0005] Preferably, the connecting component includes a guide frame, which is fixedly installed inside the mounting plate. A servo motor is fixedly installed on one side of the guide frame, and the output end of the servo motor passes through one side of the guide frame and is fixedly connected to a bidirectional screw. The end of the bidirectional screw facing away from the output end of the servo motor is rotatably connected to the inner wall of the guide frame. A slider is threaded on the outer surface of the bidirectional screw, and a plug is fixedly connected to the lower surface of the slider. The bottom end of the plug penetrates the inner wall of the guide frame. Slots for cooperating with the plug are symmetrically opened on both sides of the mating plate, and the plug is movably inserted into the slot.
[0006] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This application sets up a switchable tool assembly, designing the tool as a multi-head type with different shapes for each head. During use, different shapes of head can be flexibly switched to extend and operate according to actual processing needs, which significantly improves the flexibility of machine tool tool use. 2. This application sets up a connecting component and uses an electric drive slider to move and drive the insertion rod to accurately insert into the slot, thereby achieving stable installation of the tool structure. Compared with traditional bolt connection, this method is more stable and easier to operate, effectively improving the stability of machine tool tools during use. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] Example: Figure 1-4 As shown, this utility model provides a tooling structure for a milling-turning composite machine tool, including a mounting plate 1. The mounting plate 1 is fixedly installed on the output end of the machine tool spindle, achieving a stable connection between the tooling structure and the output end of the machine tool spindle, providing a mounting foundation for the entire tooling structure, and ensuring stable operation of the tooling with the spindle. A docking plate 4 is movably engaged on the lower surface of the mounting plate 1. The movable engagement design between the mounting plate 1 and the docking plate 4 facilitates quick docking and initial positioning, providing convenience for subsequent fixed connection. A connecting component 3 is provided between the mounting plate 1 and the docking plate 4, which can stably connect the mounting plate 1 and the docking plate 4, ensuring the reliability of the connection and avoiding the impact on machining accuracy due to loose connection during processing. A housing 5 is fixedly connected to the lower surface of the docking plate 4. A switchable tool assembly 2 is provided inside the housing 5. The switchable tool assembly 2 is located inside the housing 5, which is protected by the housing 5 and can realize the switching of different tools to meet the needs of various machining processes in milling-turning composite machining.
[0015] The switchable tool assembly 2 includes a support plate 22, which is fixedly installed on the inner wall of the housing 5. Cylinders 21 are fixedly installed in a ring array on the upper surface of the support plate 22. The cylinders 21 are installed in a ring array on the support plate 22, and their output ends drive the first circular plate 26 and the second circular plate 27 to move, which can realize the extension and retraction of the tool body 23. It is convenient to extend or retract the required tool according to the processing requirements. The output end of the cylinder 21 passes through the upper surface of the support plate 22 and is fixedly connected to the first circular plate 26. The lower surface of the first circular plate 26 is movably engaged with the second circular plate 27. A connecting bolt 28 is threaded between the first circular plate 26 and the second circular plate 27, which thread the first circular plate 26 and the second circular plate 27 to realize the detachable fixation of the two, which is convenient for the replacement or maintenance of the tool body 23.
[0016] The upper surface of the second circular plate 27 is fixedly connected with a magnetic suction rod 24 in an annular array. The lower surface of the first circular plate 26 is provided with a magnetic suction groove 25 for use with the magnetic suction rod 24 in an annular array. The corresponding magnetic suction rod 24 and magnetic suction groove 25 are magnetically inserted into each other. The magnetic insertion of the magnetic suction rod 24 and magnetic suction groove 25 plays a role in pre-positioning the first circular plate 26 and the second circular plate 27 before the connecting bolt 28 is connected, which facilitates the installation of the connecting bolt 28 and enhances the tightness of the connection between the two.
[0017] The lower surface of the second circular plate 27 is fixedly mounted with a cutter head body 23. The end shapes of the multiple cutter head bodies 23 are different from each other. The multiple cutter head bodies 23 with different end shapes are fixed on the second circular plate 27. With the extension and retraction of the cylinder 21, different cutter heads can be quickly switched to meet different turning and milling machining needs and improve machining efficiency.
[0018] The connecting component 3 includes a guide frame 31, which is fixedly installed inside the mounting plate 1. A servo motor 35 is fixedly installed on one side of the guide frame 31, and a protective shell 36 for use with the servo motor 35 is fixedly installed on one side of the guide frame 31. The servo motor 35 is fixedly installed inside the protective shell 36. The servo motor 35 provides power for the operation of the connecting component 3, and the protective shell 36 protects the servo motor 35 to prevent damage to the motor from debris, oil stains, etc. generated during processing.
[0019] Furthermore, the output end of the servo motor 35 passes through one side of the guide frame 31 and is fixedly connected to a bidirectional screw 37. The end of the bidirectional screw 37 facing away from the output end of the servo motor 35 is rotatably connected to the inner wall of the guide frame 31. The servo motor 35 drives the bidirectional screw 37 to rotate inside the guide frame 31. The rotation of the bidirectional screw 37 provides driving force for the movement of the slider 32, and the installation method at both ends ensures the stability of the rotation.
[0020] The outer surface of the bidirectional screw 37 is threaded with a slider 32. The outer surface of the slider 32 is slidably engaged with the inner wall of the guide frame 31. The slider 32 is threadedly engaged with the bidirectional screw 37 and slidably engaged with the inner wall of the guide frame 31. When the bidirectional screw 37 rotates, the slider 32 can slide stably along the guide frame 31 to achieve precise position adjustment. The slider 32 is threaded in the opposite thread direction on the outer surface of the bidirectional screw 37, and a plug rod 33 is fixedly connected to the lower surface of the slider 32. The bottom end of the plug rod 33 penetrates the inner wall of the guide frame 31. The slider 32 is threaded in the opposite thread direction of the bidirectional screw 37, so that when the bidirectional screw 37 rotates, the two sliders 32 can move synchronously in opposite directions, driving the plug rod 33 to move synchronously in opposite directions, which facilitates the insertion or disengagement of the plug rod 33 into or out of the slot 34.
[0021] The docking plate 4 has symmetrical slots 34 on both sides for use with the insert rods 33. The insert rods 33 and slots 34 are movably inserted into each other, which enables the quick fixing and separation of the mounting plate 1 and the docking plate 4, facilitating the replacement or maintenance of the entire tool structure. The insert rods 33 are symmetrically distributed, and the outer surface shape of the insert rods 33 is adapted to the inner wall shape of the slots 34. The symmetrically distributed insert rods 33 and the adapted slots 34 make the connection between the mounting plate 1 and the docking plate 4 more balanced and stable, improve the reliability of the connection, and avoid shaking during processing.
[0022] Working principle: First, the entire tool structure is fixed to the output end of the machine tool spindle by the mounting plate 1. When the spindle rotates, it drives the mounting plate 1 and the connected parts to move synchronously, providing a power basis for machining.
[0023] Mounting plate 1 and docking plate 4 are initially positioned by a movable snap-fit, and then a stable connection is completed by connecting component 3. In connecting component 3, after the servo motor 35 in the protective shell 36 is started, its output end drives the bidirectional screw 37 in the guide frame 31 to rotate. Since the slider 32 is threaded on the opposite thread direction of the bidirectional screw 37 and slides with the inner wall of the guide frame 31, when the bidirectional screw 37 rotates, it will drive the two sliders 32 to move synchronously in opposite directions, thereby driving the insert rod 33 on the lower surface of the slider 32 to move synchronously in opposite directions.
[0024] When the insertion rod 33 is inserted into the slots 34 on both sides of the docking plate 4, a firm connection between the mounting plate 1 and the docking plate 4 can be achieved; otherwise, the connection can be released, facilitating overall assembly and disassembly.
[0025] The housing 5 below the docking plate 4 provides protection and installation space for the internal switchable tool assembly 2.
[0026] In the switchable tool assembly 2, the support plate 22 is fixed to the inner wall of the housing 5 to provide stable support for the cylinders 21 in the ring array. During processing, the corresponding cylinder 21 is controlled to work according to different process requirements. Its output end pushes the first circular plate 26 and the second circular plate 27 that cooperate with it to move down, so that the tool head body 23 on the lower surface of the second circular plate 27 extends out of the housing 5 for processing.
[0027] When the cylinder 21 is not in operation, it drives the corresponding cutter head body 23 to retract, thus avoiding interference. Since the ends of the multiple cutter head bodies 23 have different shapes, different cutters can be quickly switched by switching the working state of different cylinders 21.
[0028] In addition, the second circular plate 27 and the first circular plate 26 are pre-positioned by magnetic insertion of the magnetic rod 24 and the magnetic groove 25, and then fixed by threaded connection of the connecting bolt 28. This not only ensures the connection stability, but also makes it easy to replace the cutter head body 23 separately. The first circular plate 26 and the second circular plate 27 can be separated by removing the connecting bolt 28.
[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
