[0027] Example: Please see Figures 1-5 The multi-station milling rapid positioning and clamping device in the preferred embodiment of this utility model can clamp multiple workpieces 1 at the same time, and simplifies the clamping steps, effectively improving the utilization rate of the B-axis turning and milling composite machining center table and the processing efficiency of workpiece 1.

[0028] Specifically, the multi-station milling rapid positioning and clamping device in the preferred embodiment of this example can clamp a workpiece 1 having a part to be processed 2 and a positioning cantilever 3. The multi-station milling rapid positioning and clamping device includes a rotating body 4 and several clamping mechanisms.

[0029] The rotating body 4 extends axially, and rotational support structures are provided at both ends of the rotating body 4. The rotational support structure at at least one end of the rotating body 4 can drive the rotating body 4 to rotate. Multiple mounting surfaces are provided circumferentially on the outer wall of the rotating body 4 to install multiple clamping mechanisms, thereby increasing the number of clamping mechanisms that can be installed on a single rotating body 4 and further increasing the number of workpieces 1 that can be clamped.

[0030] Furthermore, each clamping mechanism includes several locking components and a support member 5 disposed on the mounting surface. The support member 5 has a support surface on the side away from the mounting surface. The support surface has at least one clamping station. Each clamping station is provided with at least one locking component for fixing the positioning cantilever 3 to the support surface, so that the part 2 to be processed of the workpiece 1 extends to the side of the support member 5 and is in a suspended state, so as to facilitate milling.

[0031] In this embodiment, each clamping station is configured in a one-to-one correspondence with a workpiece 1, with one clamping station used to clamp one workpiece 1. In actual use, clamping stations of the same specification can be set on different support surfaces, or clamping stations of different specifications can be set to adapt to the processing requirements of different workpieces 1.

[0032] Preferably, the rotating body 4 and the supporting component 5 are integrally formed, forming a one-piece structure. This reduces the gaps and errors caused by separate assembly, resulting in stronger overall rigidity, the ability to withstand the forces during the cutting process, and reduced deformation, thereby improving processing stability. Specifically, preferably, the rotating body 4 and the supporting component 5 can be integrally milled from alloy steel, and then subjected to heat treatment after forming to improve overall rigidity and wear resistance.

[0033] Further, in a preferred embodiment, the outer wall of the rotating body 4 is provided with a plurality of mounting surfaces that extend axially at uniform intervals along the circumference, and each mounting surface is provided with a plurality of support members 5 at uniform intervals along the axial direction, so as to increase the mounting positions on the rotating body 4 for mounting more workpieces 1. Specifically, preferably, the outer wall of the rotating body 4 is provided with four mounting surfaces that extend circumferentially at uniform intervals along the circumference. More specifically, the middle region of the rotating body 4 is preferably a cuboid structure, and the four outer wall surfaces of the cuboid structure are mounting surfaces. Of course, the middle region of the rotating body 4 can also be other polygonal prism structures, as long as they can meet the avoidance distance of the workpieces 1 on each support surface, for example, a triangular prism, a pentagonal prism, or a hexagonal prism.

[0034] More preferably, a clearance surface 8 is provided between two support members 5 located on adjacent mounting surfaces at the same axial position to avoid the movement trajectory of the milling cutter. This allows the milling cutter to perform milling operations on the workpiece 1 according to a pre-set movement trajectory, and the cutter will not collide with the rotating body 4 when cutting around the workpiece 1. In this embodiment, the rotating body 4 has several support members evenly distributed circumferentially at regular intervals along the axial direction, so that all clamping positions are symmetrically distributed around the rotating body 4, which can improve the balance of this clamping device and counteract the cutting force.

[0035] Preferably, the clearance surface 8 is an inclined surface or a circular arc surface. Preferably, the depth and width of the clearance groove formed by the clearance surface are adapted to the range of motion of the milling cutter in the B-axis milling-turning machining center.

[0036] Furthermore, each support surface preferably has two clamping stations, so that the two positioning cantilevers 3 of the two workpieces 1 can be mounted back-to-back on the support surface. In this preferred embodiment, the two positioning cantilevers 3 are mounted back-to-back on the support surface, which can not only form a constraint on each other and increase the stability of the workpieces 1 during the processing, but also save clamping space on the rotating body 4 to clamp more workpieces 1.

[0037] In a preferred embodiment, the support surface has a positioning groove 6, and the clamping station is located at the bottom of the positioning groove 6 to facilitate the positioning of the positioning cantilever 3. Specifically, the positioning groove 6 extends axially to achieve stable positioning of both ends of the positioning cantilever 3. Preferably, a wear-resistant pad is provided at the bottom of the positioning groove 6. The wear-resistant pad is preferably made of metal or a polymer wear-resistant material to reduce wear on the workpiece 1 during clamping.

[0038] More preferably, a plurality of locking components are provided between the positioning cantilever 3 and the clamping station, and the plurality of locking components are preferably arranged in a matrix to achieve a stable connection between the positioning cantilever 3 and the clamping station. In a specific preferred embodiment, two locking components are provided between each positioning cantilever 3 and the clamping station.

[0039] Further, in a preferred embodiment, the locking component includes a bolt and a screw hole 7. The screw hole 7 is disposed in the clamping station, and a corresponding through hole is provided on the positioning cantilever 3. In actual use, the positioning cantilever 3 is placed in the clamping station, with the through hole on the positioning cantilever 3 corresponding to the screw hole 7 on the clamping station. Finally, the bolt passes through the through hole and is rotated and screwed into the screw hole 7 until the nut limits the positioning cantilever 3 to the clamping station, thereby completing the limiting of the workpiece 1.

[0040] More preferably, the support surface of the support member 5 is higher than the mounting surface, so that when the workpiece 1 is installed in the clamping position, a clearance space 10 can be formed under the positioning cantilever 3, so that when the milling cutter cuts the area around the workpiece 1, it will not collide with the clamping mechanism.

[0041] Furthermore, at least one positioning plane 9 is provided on the rotating body 4 to facilitate the alignment of the rotating body 4. Preferably, the positioning plane 9 is parallel to a certain support surface, and the positioning plane 9 is provided on the rotating body 4 on both sides of the cuboid.

[0042] More preferably, the rotating support structure is a machine tool, which includes a rotating shaft and a chuck. The chuck is mounted on the rotating shaft, and the rotating shaft is detachably fixed to the end of the rotating body 4.

[0043] More specifically, in the preferred embodiment of this application, both sides of the rotating body 4 are provided with claw clamps, or one side of the rotating body 4 is provided with a claw clamp and the other side is provided with a tip.

[0044] Preferably, the chuck is a three-jaw chuck, a four-jaw chuck, or a five-jaw chuck.

[0045] More preferably, a central frame is provided in the middle of the rotating body 4 to provide stable support for the rotating body 4.

[0046] The multi-station milling rapid positioning and clamping device of this utility model reduces the obstruction of the rotating body to the workpiece 1, increases the machined parts, and enables more processes of the workpiece 1 to be completed in one clamping, reducing the number of clamping times and clamping errors. It optimizes the multi-station positioning and clamping method of the workpiece 1, maximizes the utilization rate of the worktable, and can adapt to the batch processing requirements of different workpieces 1 and multiple stations. It has high positioning accuracy, is easy to operate, and has high efficiency, and has good application prospects and promotion value.
