In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is 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 invention and are not intended to limit the invention.

Referring to fig. 1 to 7, the multifunctional component fixing device of the present invention will now be described. The multifunctional component fixing device comprises a workbench 200 for placing a component 100, a transverse clamping mechanism 300 for providing transverse clamping force to the component 100, a vertical clamping mechanism 400 for providing vertical clamping force to the component 100, and a flexible clamping mechanism 500 for flexibly clamping the component 100; the workbench 100 comprises a central plate 210 and a plurality of circumferential plates 220 arranged along the circumference of the central plate 100, wherein different lifting mechanisms 230 are respectively connected with the central plate 210 and the circumferential plates 220; a turnover mechanism 240 is disposed between at least one of the circumferential plates 220 and the corresponding lifting mechanism 230, so that the plate surface of the circumferential plate 220 can be turned over from the state of the plate surface being horizontal to the direction of the central plate 210 to be in the state of the plate surface being vertical through the turnover mechanism 240, and can be switched between the state of the plate surface being horizontal and the state of the plate surface being vertical.

The multi-functional component fixing device that this embodiment provided compares with prior art, has following beneficial effect:

By adopting the way that the central plate 210 and the circumferential plate 220 are lifted respectively, the central plate 210 is higher than the circumferential plate 220, the circumferential plate 220 is avoided, more processing space can be exposed, as shown in the state of fig. 6, the processing reserved space is effectively increased, and the processing difficulty is reduced.

3. By giving the turning function to at least one of the circumferential plates 220, the turning of the component 100 placed on the workbench 100 can be controlled by controlling the turning state of the circumferential plate 220, for example, the component 100 is turned, and then the workbench 200 is controlled to be switched from the state of fig. 5 to the state of fig. 4, so that the manual turning by an operator is not needed, and the labor intensity of workers is reduced.

As a way of assembling the elevating mechanism 230 with the central plate 210 and the circumferential plate 220, the elevating end may form a bracket structure (as shown in fig. 4 to 6) having a large area, so as to provide a sufficient installation space for the central plate 210, the circumferential plate 220 and the structure for controlling the turning. The power part of the lifting mechanism 230 may adopt a cylinder, a hydraulic cylinder, a linear driving motor, and the like, and is not limited herein.

In specific implementation, the required circumferential plate 220 is determined according to the size of the cross section of the component 100, and the non-adaptive circumferential plate 220 is driven by the corresponding lifting mechanism 230 to move downwards, so that more operation space is provided for component processing; also, the fitted circumferential plate 220 may satisfy the moving and overturning functions of the member 100 by the overturning of the circumferential plate 220. For components 100 that require less operating space, all of the circumferential plates 220 may be moved upward to be flush with the central plates 210, which cooperate to provide a larger support plane.

In some embodiments, referring to fig. 1 to 6, in consideration of the applicability of the placement space, in this embodiment, the workbench 200 is set to be square, and correspondingly, the two circumferential plates 220 are set to be two and are both U-shaped members, the two circumferential plates 220 are spliced to form a "return" type frame, a central plate 210 is disposed in a hollow position in the middle of the frame, and the splicing position of the two circumferential plates 220 is a position where the rotating shaft of the circumferential plate 220 capable of being turned over is located. It should be understood that the shape of the worktable 200 and the manner of abutting the circumferential plate 220 may satisfy the actual working requirements and the assembling requirements, and are not limited thereto.
