Needless to say, the content protected by the present utility model does not involve improvements to software and methods.

[0033] The working principle of the clamping and fixing device for mechanical processing provided by the utility model is as follows:

[0034] This solution also has an electric control cabinet, which is installed on the equipment. When in use, each electrical device can be started and operated through the electric control cabinet. The power connection method of each electrical device is an existing mature technology, which is a well-known technology for people in this field and will not be described in detail here.

[0035] When in use, the mechanical workpiece to be processed is placed on the processing table 1, and the hydraulic cylinder 1 5 and the hydraulic cylinder 2 7 are first started to drive the positioning frame 2 and the fixed frame 3 to move, so that the distance between the bottom of the vertical section of the positioning frame 2 and the processing table 1 is less than the height of the workpiece, and at the same time, the distance between the horizontal end of the positioning frame 2 and the processing table 1 is greater than the height of the workpiece, and then the driving motor 16 is started to drive the driving rod 13 on its output shaft to rotate. Under the drive of the same synchronous belt 23, the two driving rods 13 rotate synchronously, so that the two driving frames 14 are driven, so that the fixed plate 4 pushes the workpiece to move toward the positioning frame 2;

[0036] When the workpiece contacts the vertical section of the positioning frame 2, the fixing plate 4 stops moving.

When the fixing plate 4 moves to the position of the drop opening 17, the workpiece has left the processing table 1, and the fixing plate 4 passes through the drop opening 17 into the driving groove 12. Then the driving motor 16 is started to drive the driving rod 13 to drive the fixing plate 4 to move along the driving groove 12 to the upper material side.

The setting of the drop port 17 facilitates the unloading of the fixed plate 4 into the driving groove 12, so as to facilitate the delivery of new workpieces to be processed. The setting of the rising port 18 facilitates the fixed plate 4 to leave the driving groove 12 and return to the processing table 1 again to push the workpiece for positioning. The hydraulic cylinder 20 facilitates the pushing plate 21 to enter the driving groove 12, so that the pushing plate 21 pushes the fixed plate 4 to leave the driving groove 12 through the rising port 18, so as to facilitate the resetting of the fixed plate 4.
