firstly, to the processing of same type work piece to carrying out the horizontal processing to the work piece for the example, crossbeam mechanism does not need the contained angle motion this moment, when processing same position to this type work piece, can fixed cutter A, finishes when a work piece processing, rotates frock carousel 90 for next work piece is located crossbeam mechanism below and parallel and processes, circulates in proper order, when needs processing work piece next position, mobilizes cutter A's position, and the circulation is once more circulated. In this way, the number of times of moving the adjustment tool A can be reduced, and the workpieces processed in the same batch can be kept consistent in height.
Secondly, the same group of workpieces are different workpieces forming the same device, and according to the requirements of the device on different processing positions on the workpieces, for example, a first workpiece processing position a, a second workpiece processing position B, and so on, the tool a can be adjusted to cooperate with the tool tray 90 to rotate, so that the processing procedures of different positions of the same group of workpieces can be realized at one time.
Besides, the included angle motion of the tooling turntable 90 of the embodiment in cooperation with the beam mechanism can also realize multiple processing modes of the same workpiece, specifically as follows:
thirdly, for a thick workpiece, for example, both sides of the workpiece need to be machined with the same structure, but since the machining tool can only machine one side surface, the workpiece generally needs to be manually fixed again when the other side surface of the workpiece is machined, but in the embodiment, the other side surface can be machined by rotating the tool turntable 180 degrees, and the machined workpiece is shown in fig. 7, for example, where a circle indicates the machined structure.
Fourth, the same structure needs to be machined at different positions on the same workpiece, and the same structure on the workpiece is formed into a certain regular or irregular line, such as a circular line, and a sinusoidal line, as shown in fig. 8.
Further, a rotation adjusting area 98 is arranged at the center of the bottom end surface of the workpiece bearing table 93, a plurality of grooves 99 connected with the output shaft of the rotating shaft driving device 92 are arranged in the rotation adjusting area 98, one groove 99 is located at the center of the workpiece bearing table 93, and the workpiece bearing table 93 rotates around different grooves 99 to form different movement ranges of the workpiece a.
In addition, the included angle movement range of the beam mechanism in this embodiment generally exceeds the length range of the workpiece, that is, the farthest position of the movement of the connection position of the first beam mechanism 3 and the second beam mechanism 4 generally reaches or exceeds the edge of the tooling pallet 90.
An umbrella-shaped structure for supporting the bottom end surface of the workpiece bearing table 93 is further disposed on the output shaft of the rotating shaft driving device 92, which is not shown in the drawing, the output shaft passes through the umbrella-shaped structure and is connected in the groove 99, the umbrella-shaped structure is fixed on the output shaft, and the umbrella-shaped structure is mainly used for maintaining the stability of the whole workpiece bearing table 93.
The above embodiments are only exemplary embodiments of the present application, and are not intended to limit the present application, and the protection scope of the present application is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present application and such modifications and equivalents should also be considered to be within the scope of the present application.
