The positioning table for mechanical processing includes:

[0026] A support frame 8, one side of the support frame 8 is fixedly connected to the front surface of the box body 1, the upper part of the support frame 8 is rotatably connected to the rotating shaft 12, the lower end of the rotating shaft 12 is fixedly connected to the turntable 13, the lower surface of the turntable 13 is fixedly connected to the rocker arm 14 at a position deviating from the center of the circle, the lower end of the rocker arm 14 is fixedly connected to the connecting plate 15, the rear side of the connecting plate 15 is rotatably connected to the second connecting rod 19, the two ends of the second connecting rod 19 are fixedly connected to the first ear plate 16, the side of the first ear plate 16 is fixedly connected to the first connecting rod 17, and the rear end of the first connecting rod 17 is fixedly connected to the push plate 18.

[0028] The upper end of the rotating shaft 12 is fixedly connected to the output end of the third motor 9 , and the third motor 9 is fixedly connected to the upper surface of the supporting frame 8 .

[0029] The working principle of the positioning table for mechanical processing provided by the utility model is as follows:

[0030] After processing of one side of the workpiece is completed, the nut 7 is loosened, and the rotating shaft 6 is rotated to flip the support frame 2 to the opposite side, and then the nut 7 is tightened again, and the second electric push rod 11 is extended to fix the support frame 2 to prevent the nut 7 from loosening during vibration and causing the support frame 2 to rotate, and then the third motor 9 is turned on to drive the rotating shaft 12 to rotate. Under the rotation of the rotating shaft 12, the turntable 13 also starts to rotate and makes the rocker 14 do circular motion. Then the connecting plate 15 connected to the rocker 14 also starts to do eccentric motion with the movement of the rocker 14, and the first connecting rod 17 slides back and forth under the eccentric motion of the connecting plate 15, so that the push plate 18 pushes the support frame 2 to make it vibrate. This mechanism can shake off the debris left on the surface of the workpiece during processing and store the debris into the box body 1, so as to achieve the cleaning effect and prevent the debris from falling to the ground and causing inconvenience in cleaning.

[0031] Compared with the related art, the positioning table for mechanical processing provided by the utility model has the following beneficial effects:

[0032] The support frame 2 can be vibrated by a vibration mechanism to clean up the debris generated during the processing of the workpiece and remaining on the surface of the workpiece, and the debris is stored in the box body 1, which not only cleans the workpiece but also prevents the debris from falling to the ground.

The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0035] Specifically, the difference of the positioning table for mechanical processing provided in the second embodiment of the present application lies in that, the positioning table for mechanical processing, the box body 1, the left and right sides of the box body 1 are rotatably connected to the rotating shaft 6, the supporting frame 2 is fixedly connected between the rotating shafts 6, the front surface of the supporting frame 2 is symmetrically fixedly connected to two second fixed blocks 4, the two second fixed blocks 4 are rotatably connected to the first screw 24, the rear surface of the supporting frame 2 is symmetrically fixedly connected to the two first fixed blocks 3, the two first fixed blocks 3 are fixedly connected to the sliding rod 23, the sliding rod 23 and the rod body of the screw are movably connected to the sliding block 5, and the sliding blocks 5 are rotatably connected to the second screw 22.

[0036] The left and right side surfaces of the support frame 2 are symmetrically fixedly connected to two second electric push rods 11 , and the left and right side surfaces of the box body 1 are provided with limiting grooves 10 corresponding to the positions of the output ends of the second electric push rods 11 .

[0037] The second screw rod 22 is movably connected to a second ear plate 25 , the upper surface of the second ear plate 25 is fixedly connected to a first electric push rod 26 , and the lower end of the first electric push rod 26 is fixedly connected to a clamping plate 27 .

Under the action of the first electric push rod 26, the clamping plate 27 moves downward and clamps the workpiece, and then the first motor 20 is turned on. Under the action of the first motor 20, the first screw rod 24 starts to rotate, and the slider 5 starts to move left and right with the forward and reverse rotation of the first screw rod 24, so that the left and right positions of the workpiece can be positioned.
