[0015] The present utility model will be further described below with reference to the accompanying drawings.

[0016] As described in the attached Figures 1 to 3 A rocking plate pressing and positioning mechanism includes a support table 1, a rocking handle 2, and a pushing and pulling mechanism. One end of the rocking handle 2 is hingedly installed on a support 3, and the pushing and pulling mechanism can push and pull the rocking handle 2 to rock on the support 3. The other end of the rocking handle 2 is provided with a rocking plate 4, and the rocking plate 4 is integrally connected with the rocking handle 2. The rocking plate 4 can rock together with the rocking handle 2, and the lower plate surface of the rocking plate 4 faces the upper surface of the support table 1. A pressing plate 5 is arranged below the rocking plate 4, and the pressing plate 5 is hingedly matched with the rocking plate 4. When the pushing and pulling mechanism pushes the rocking handle 2, the rocking plate 4 rocks with the rocking handle 2 and presses towards the support table 1, and the pressing plate 5 also presses towards the support table 1 along with the rocking plate 4. Since the pressing plate 5 is hingedly matched with the rocking plate 4, the pressing plate 5 can rotate relative to the rocking plate 4 to change the angle of the pressing plate 5. When a plate-shaped part is placed on the support table 1, the pressing plate 5 can press the plate-shaped part on the support plate to realize the fixation of the plate-shaped part. And because the angle of the pressing plate 5 is variable, when the thickness of the plate-shaped part changes, the pressing plate 5 can adaptively change the angle so that the lower plate surface of the pressing plate 5 remains in contact with the upper plate surface of the plate-shaped part, thereby enabling the pressing plate 5 to tightly press on the plate-shaped part.

[0017] As described in the attached Figure 3As shown in the figure, an arc-shaped groove 6 is formed on the lower plate surface of the rocker plate 4, and a plug shaft 7 is provided at the upper end of the pressing plate 5. The outer diameter of the plug shaft 7 is equivalent to the inner diameter of the arc-shaped groove 6. The plug shaft 7 is rotatably inserted into the arc-shaped groove 6 so that the pressing plate 5 is hinged to the rocker plate 4, and the pressing plate 5 can rotate relative to the rocker plate 4 to change the angle of the pressing plate 5. The rocker handle 2 is hinged to the support 3 through a rotating shaft 8. Both the rotating shaft 8 and the plug shaft 7 are transverse shafts, and the rotating shaft 8 and the plug shaft 7 are parallel to each other. The upper surface of the support table 1 is a horizontal plane. Thus, during the rotation of the rocker handle 2, the lower plate surface of the pressing plate 5 can change the angle to fit the upper plate surface of the plate-shaped part.

[0018] Specifically, both the rocker plate 4 and the pressing plate 5 are transverse long strip-shaped plates, and the arc-shaped groove 6 is a long strip-shaped groove. The arc-shaped groove 6 extends along the length direction of the rocker plate 4 correspondingly. At least one end of the arc-shaped groove 6 is open, and the plug shaft 7 can slide and be inserted into the arc-shaped groove 6 from the open end of the arc-shaped groove 6 to install the pressing plate 5 below the rocker plate 4.

[0019] A threaded through hole 9 is formed on the rocker plate 4, and the threaded through hole 9 communicates with the open end of the arc-shaped groove 6. The limit bolt can be screwed from the threaded through hole 9 to the open end of the arc-shaped groove 6 to limit the plug shaft 7 from sliding out of the arc-shaped groove 6, thereby preventing the pressing plate 5 from separating from the rocker plate 4.

[0020] The pushing and pulling mechanism includes a pushing and pulling cylinder 10, and a telescopic rod 11 is provided at the front end of the pushing and pulling cylinder 10. As shown in the appendix Figure 3 As shown in the figure, the telescopic rod 11 is a horizontal rod body, and the telescopic rod 11 is connected to the rocker handle 2 through a movable connecting rod 12; when the telescopic rod 11 expands and contracts, the rocker handle 2 is pushed and pulled through the movable connecting rod 12. Both ends of the movable connecting rod 12 are rotatably connected to the telescopic rod 11 and the rocker handle 2 respectively. The rocker handle 2 is in a folded angle shape, and the movable connecting rod 12 is correspondingly connected to the bent part of the rocker handle 2.

[0021] The working principle of the present invention is as follows: Place the plate-shaped part to be fixed on the support table 1, start the pushing and pulling cylinder 10, the telescopic rod 11 extends, push the rocker handle 2 to swing, and the rocker plate 4 flips downward along with the rocker handle 2, so that the pressing plate 5 below the rocker handle 2 presses on the plate-shaped part correspondingly, thereby fixing the plate-shaped part on the support table 1 for subsequent processing operations such as welding of the plate-shaped part. And because the pressing plate 5 can rotate relative to the rocker plate 4, when the thickness of the plate-shaped part is different, the pressing plate 5 can adaptively change the angle so that the lower plate surface of the pressing plate 5 can always fit the upper surface of the plate-shaped part.

[0022] The above is only the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
