Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing equipment technology, and in particular relates to a milling and turning machine tool. Background Technology

[0002] In the field of machining, turning and milling machine tools are widely used in the production of shaft and disc parts because they can perform turning and milling simultaneously.

[0003] However, most existing milling and turning machines rely on fixed guideways to drive the milling cutter's movement trajectory during milling operations, which can only achieve machining in a single direction or at a fixed angle. When faced with complex curved surfaces and multi-station machining requirements, it is necessary to frequently disassemble the workpiece and adjust the clamping position, which not only reduces machining efficiency but also easily causes errors due to repeated positioning, affecting the accuracy of the parts.

[0004] Other machine tools with adjustable angles often use multiple sets of cylinders or hydraulic rods for linkage control, which results in complex structures and high costs. Utility Model Content

[0005] In view of the above problems, the purpose of this utility model is to provide a turning and milling machine tool, which aims to solve the problem that the existing turning and milling machine tools have a complex structure and can only perform machining in a single direction or at a fixed angle.

[0006] The present invention adopts the following technical solution:

[0007] The milling and turning machine includes a frame, a support platform on the front of the frame, a clamping platform on the front of the support platform, an arc-shaped opening at the top of the support platform, a rotating disk placed within the arc-shaped opening, a rotating shaft rotatably mounted at the eccentric position of the rotating disk, a chuck at the front end of the rotating shaft, a linkage shaft rotatably mounted at the rear end of the rotating shaft, a connecting shaft rotatably mounted on the back of the frame, the connecting shaft being rotatably connected to the tail end of the linkage shaft, a milling cutter clamped on the chuck, a milling and turning motor for driving the connecting shaft to rotate on the frame, and an adjustment assembly for driving the rotating disk to rotate on the frame.

[0008] Furthermore, the adjustment assembly includes a central gear plate mounted on the front of the rotating disk, a top seat above the frame, a rotating shaft on the top seat, a rotating gear on the rotating shaft, a support gear rotating around the arc-shaped opening inside the support platform, and the central gear plate meshing with the rotating gear and the support gear respectively. A rotary reduction motor is mounted on the top seat, which drives the rotating shaft to rotate.

[0009] Furthermore, the intermediate gear disc has an adjustment notch, and the rotating shaft is located within the adjustment notch.

[0010] Furthermore, the shaft of the supporting gear is provided with front and rear retaining rings, and the intermediate gear plate is located inside the front and rear retaining rings.

[0011] Furthermore, the support platform includes three support plates: front, middle, and rear. The clamping platform is installed on the front support plate, and an arc-shaped limiting plate is provided on the back of the rear support plate. A support gear is rotatably arranged between the arc-shaped limiting plate and the middle support plate. The rotating disk is located between the arc-shaped limiting plate and the rear retaining ring.

[0012] The beneficial effects of this utility model are:

[0013] 1. This machine tool uses the meshing transmission between the intermediate gear plate, rotating gear, and support gear to enable precise angle adjustment of the rotating plate, meeting the multi-directional machining needs of complex parts.

[0014] 2. This machine tool adopts a double limiting structure of front and rear retaining rings and arc-shaped limiting plates, which effectively restrains the axial movement and radial runout of the intermediate gear plate and the rotating plate, ensuring the stability of the milling cutter during rotation.

[0019] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0020] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0021] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0022] Combination Figure 1-4As shown, the milling and turning machine includes a frame 1. A support platform 2 is provided on the front of the frame 1, and a clamping platform 3 is provided on the front of the support platform 2. An arc-shaped opening 4 is opened on the top of the support platform 2. A rotary disk 5 is placed within the arc-shaped opening 4. A rotating shaft 6 is rotatably provided at the eccentric position of the rotary disk 5. A chuck 7 is provided at the front end of the rotating shaft 6, and a linkage shaft 9 is rotatably provided at the rear end. A connecting shaft 10 is rotatably provided on the back of the frame 1. The connecting shaft 10 is rotatably connected to the tail end of the linkage shaft 9. A milling cutter 8 is clamped on the chuck 7. A milling and turning motor 11 for driving the connecting shaft 10 to rotate is provided on the frame 1. An adjustment assembly for driving the rotary disk 5 to rotate is provided on the frame 1.

[0023] In this machine tool, the frame serves as the carrier of the entire machine tool, and a support platform is set on its front. An arc-shaped opening is opened at the top of the support platform, and a rotary table is placed within the arc-shaped opening. Driven by the adjustment components, the rotary table can rotate at a specific angle within the arc-shaped opening to adjust the position of the milling cutter.

[0024] Because the linkage shaft has universal joints at both ends, and the two universal joints are rotatably connected to the rotating shaft and the connecting shaft respectively, this allows for two main benefits. Firstly, during milling, the milling motor drives the connecting shaft to rotate, and the power is transmitted to the rotating shaft via the coupling, ultimately driving the milling cutter on the chuck to rotate, thus achieving the milling action. Secondly, during cutter position adjustment, the linkage shaft ensures smooth adjustment of the cutter position.

[0025] As a preferred structure, combined with Figure 2-3 The adjustment assembly includes a central gear 12 mounted on the front of the rotating disk 5. A top seat 13 is provided above the frame 1. A rotating shaft 14 is provided on the top seat 13. A rotating gear 15 is provided on the rotating shaft 14. A support gear 16 is provided inside the support platform 2, rotating around the arc-shaped opening. The central gear 12 meshes with the rotating gear 15 and the support gear 16 respectively. A rotary reduction motor 18 is provided on the top seat 13. The rotary reduction motor 18 is used to drive the rotating shaft 14 to rotate.

[0026] When it is necessary to adjust the milling cutter machining angle, start the rotary gear motor. The rotary gear motor drives the rotary shaft to rotate, and the rotary shaft drives the intermediate gear disk that meshes with the rotary gear to rotate. The intermediate gear disk is supported by the support gear, which drives the rotary disk to make a circular motion along the arc-shaped opening of the support table. Since the rotating shaft is installed in an eccentric position on the rotary disk, the rotating shaft changes position when the rotary disk makes a circular motion, thereby realizing the adjustment of the milling cutter machining position.

[0027] The intermediate gear disk 12 has an adjustment notch 19, and the rotating shaft is located within the adjustment notch. When the intermediate gear disk rotates, the rotating shaft is always located within the adjustment notch. The adjustment notch serves to avoid interference with the rotating shaft.

[0028] In this structure, Figure 3In this configuration, each of the support gears 16 has a front and rear retaining ring 20 on its shaft. The intermediate gear disk 12 meshes with all the support gears 16 and is located within the front and rear retaining rings. The front and rear retaining rings limit the movement of the intermediate gear disk, preventing axial displacement during rotation and ensuring more stable rotation of the rotating disk.

[0029] In this machine tool, combined Figure 3-4 The support platform 2 includes three support plates 21: front, middle, and rear. A clamping table is installed on the front support plate to fix the workpiece, facilitating clamping and positioning. An arc-shaped limiting plate 22 is provided on the back of the rear support plate. A ring of supporting gears 16 is rotatably arranged between the arc-shaped limiting plate and the middle support plate. The rotating disk is located between the arc-shaped limiting plate 22 and the rear retaining rings. The arc-shaped limiting plate and all the rear retaining rings form a front and rear limiting range. The rotating disk is located within this limiting range, which guides and limits the rotation of the rotating disk, further stabilizing its rotation.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
