Through the cooperation of these mechanisms, automatic flipping and double-sided machining of the workpiece are achieved; wherein,
[0026] The support mechanism includes a support platform 1, and multiple installation platforms are provided on top of the support platform 1. The installation platforms are rotatably positioned on top of the support platform via a rotating component.
[0027] In a preferred embodiment, the installation platform includes a base plate 2, two upright plates 3 are symmetrically fixedly arranged on the top surface of the base plate 2, and a top plate 4 is fixedly arranged on the top surface of the two upright plates 3. The top plate 4 is arranged parallel to the base plate 2. The installation platform provides assembly space for the clamping components.
[0028] In a preferred embodiment, the rotating assembly includes symmetrically fixed support plates 5 on the top surface of the support platform 1 located on both sides of the corresponding mounting platform, with the upper part of the support plate 5 rotatably connected to the corresponding side of the mounting platform; that is, the mounting platform is rotatable between the two support plates 5.
[0029] The clamping mechanism has multiple clamping components on the corresponding mounting platform. The clamping components are set on the corresponding mounting platform and are used to clamp and fix the workpiece.
[0030] In a preferred embodiment, the clamping assembly includes clamping cylinders 6 symmetrically fixed on the bottom surface of the top plate 4. The piston rod of the clamping cylinder 6 is provided through the top plate 4 and can be raised and lowered. A strip-shaped clamping block 7 is provided on the top surface of the piston rod of the clamping cylinder 6. One end of the clamping block 7 is hinged to the transmission end of the piston rod of the corresponding clamping cylinder 6. The two clamping blocks 7 are arranged opposite to each other for clamping and fixing the workpiece.
[0031] Hinged support rods 8 are symmetrically arranged on both sides of the clamping block 7 on the top surface of the top plate 4. The bottom end of the hinged support rod 8 is hinged to the top surface of the top plate 4, and the top end of the hinged support rod 8 is rotatably connected to the corresponding side of the clamping block 7. The two hinged support rods 8 configured for each clamping block 7 are used to improve the stability of the clamping block 7 in the process of clamping the workpiece 15.
[0032] A limiting plate 9 is fixedly provided on the top surface of the top plate 4 on one side of the clamping block 7 to support and limit the workpiece 15 after clamping.
[0033] The flipping mechanism has multiple flipping components corresponding to the clamping components. The flipping components are set on the top surface of the support platform 1 and located on one side of the mounting platform, and are used to flip the workpiece 15 for subsequent processing.
[0034] In a preferred embodiment, the flipping assembly includes a limiting platform 10 fixedly disposed on the top surface of the support platform 1, located on the side of the mounting platform near the limiting plate 9. A flipping cylinder 11 is symmetrically disposed on the side of the limiting platform 10 near the mounting platform. The bottom end of the flipping cylinder 11 is hinged to the side wall of the limiting platform 10, and the transmission end of the piston rod of the flipping cylinder 11 is hinged to the side of the base plate near the limiting platform 10, for driving the mounting platform to flip.
[0035] In this process, after the installation platform is rotated 90 degrees, the limiting plate 9 abuts against the top surface of the limiting table 10, limiting the installation platform and clamping components as a whole, which facilitates the processing of the other side of the workpiece 15.
[0036] The limiting mechanism has multiple sets of limiting components on the corresponding installation platform. The limiting components are located on the support platform 1 below the installation platform and are used to limit and fix the clamping mechanism.
[0037] In a preferred embodiment, the limiting component includes rectangular mounting grooves 12 disposed on the support platform 1 below the corresponding base plate. A vertical limiting cylinder 13 is fixedly disposed inside the mounting groove 12. A limiting rod 14 is fixedly disposed at the transmission end of the piston rod of the limiting cylinder 13. The limiting rod 14 and the corresponding mounting groove 12 are connected by a sliding connection. The limiting rod 14 is used to support and limit the mounting platform.
[0038] The working principle of this utility model:
[0039] In the initial state, the limiting rod 14 is driven by the limiting cylinder 13 to extend out of the top surface of the support platform 1 and abut against the bottom surface of the base plate 2 to support the mounting platform. At this time, the base plate 2 of the mounting platform is in a horizontal state. The workpiece 15 is placed on the top surface of the top plate 4 between the two clamping blocks 7. Then, the clamping cylinder 6 drives the clamping blocks 7 to rotate towards the workpiece 15 to clamp and fix the workpiece 15. Then, the top surface of the workpiece 15 is processed.
[0040] When it is necessary to flip the workpiece 15, the limiting cylinder 13 drives the limiting rod 14 to descend into the installation groove 12, and then the flipping cylinder 11 drives the installation platform to flip 90 degrees to the side closer to the limiting table 10, so that the outer side of the limiting plate 9 abuts against the top surface of the limiting table 10, so that the side of the workpiece 15 faces upward, which is convenient for processing the side.
[0041] The above process enables the automatic flipping of workpiece 15, allowing for the processing of both sides of workpiece 15. Furthermore, the automatic flipping occurs during the clamping process, avoiding the tedious process of disassembling the fixture and then re-clamping it, thus improving the processing efficiency and accuracy of the workpiece.
