[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] The present invention provides a Figures 1-4 shown sheet metal processing flipping clamping device, including,

[0025] Base 1, and support plates 2 are respectively arranged on both sides of the top end of the base 1;

[0026] Hydraulic rods 5, and connecting plates 4 are respectively arranged at one ends of the two hydraulic rods 5;

[0027] Motors 3 are respectively arranged on one side of the two support plates 2, arc-shaped grooves are respectively opened on one side of the two support plates 2, limit rods 11 are respectively arranged on one side of the two connecting plates 4, and clamping components are respectively arranged at one ends of the two hydraulic rods 5;

[0028] The two clamping components respectively include vertical plates 6, first clamping plates 7, second clamping plates 8, blocks 9 and screw rods 10. The two screw rods 10 are respectively arranged at the top ends of the two first clamping plates 7, and the two second clamping plates 8 are respectively arranged on one side of the two vertical plates 6.

[0029] Both sides of the top end of the base 1 are fixedly connected to the bottom ends of the two support plates 2. Horizontal plates are respectively fixedly connected to one side of the two support plates 2. The bottom ends of the two motors 3 are respectively fixedly connected to the top ends of the two horizontal plates. First circular through grooves are respectively opened on one side of the two support plates 2. The output ends of the two motors 3 are respectively inserted into the first circular through grooves. The output ends of the two motors 3 are respectively fixedly connected to one side of the two connecting plates 4. One ends of the two limit rods 11 are respectively fixedly connected to one side of the two connecting plates 4. The other ends of the two limit rods 11 are respectively clamped with the two arc-shaped grooves. The other sides of the two connecting plates 4 are respectively fixedly connected to the other ends of the two hydraulic rods 5. The output ends of the two hydraulic rods 5 are respectively fixedly connected to the other sides of the two vertical plates 6.

[0030] The motor 3 and the hydraulic rod 5 are prior arts and are both electrically connected to an external control power supply. The hydraulic rod 5 is an electric hydraulic rod, and its telescopic control can be achieved through a controller. The support plate 2, the motor 3, the connecting plate 4, the hydraulic rod 5, the limiting rod 11 and the clamping assembly form a set, and two sets are symmetrically arranged with respect to the central axis of the base 1. The arc-shaped groove is opened at an angle of 180 degrees, so as to limit the rotation angle of the connecting plate 4 between 0 and 180 degrees. The angle of the arc-shaped groove is not unique and can be modified according to actual needs.

[0031] On one side of each of the two vertical plates 6, a T-shaped groove is opened. Two clamping blocks 9 are respectively clamped with the two T-shaped grooves. One end of each of the two clamping blocks 9 is fixedly connected to one side of each of the two first clamping plates 7. At the top of the inner wall of each of the two T-shaped grooves, a second circular through groove is opened. Threads are respectively opened on the inner walls of the two second circular through grooves. Two lead screws 10 are respectively meshed with the threads of the two second circular through grooves. Bearings are respectively sleeved at the bottom of the two lead screws 10. The bottom ends of the two bearings are respectively fixedly connected to the top ends of the two clamping blocks 9. One side of each of the two second clamping plates 8 is fixedly connected to the bottom end of one side of each of the two vertical plates 6. Rubber pads are respectively fixedly connected to the bottom ends of the two first clamping plates 7 and the top ends of the two second clamping plates 8.

[0032] The T-shaped groove is a horizontal cross-section, and the clamping block 9 is T-shaped. The size of the T-shaped groove is 1.05 times the size of the clamping block 9. The thread on the inner wall of the second circular through groove is meshed with the thread on the outer wall of the lead screw 10. Thus, by rotating the lead screw 10, the lead screw 10 can move in the direction away from and close to the vertical plate 6. The bearing is a ball bearing, which is a prior art. The bearing restricts the lead screw 10 to only rotate and cannot perform displacement in other directions. The rubber pad is beneficial to protecting the sheet metal from being damaged during clamping.

[0033] The working principle of the present utility model:

[0034] When a staff member uses this device, it is necessary to first place both sides of the sheet metal into the two side clamping assemblies respectively, and then start the hydraulic rod 5 to make the vertical plates 6 on one side of the two clamping assemblies close to one side of the sheet metal. Then rotate the lead screw 10 clockwise. The lead screw 10 is meshed with the second circular through groove, so that the lead screw 10 moves in the direction close to the second clamping plate 8. The lead screw 10 drives the clamping block 9, and the clamping block 9 drives the first clamping plate 7 to move synchronously, so as to clamp both sides of the sheet metal by the first clamping plate 7 and the second clamping plate 8, and fix the sheet metal firmly;

[0035] Then start the motor 3. The motor 3 drives the connecting plate 4 to rotate. The connecting plate 4 drives the hydraulic rod 5, and the hydraulic rod 5 drives the rotation of the clamping assembly, so as to realize the flipping of the sheet metal.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
