[0012] It should be noted that when an element is referred to as "fixed to" or "set to" another element, it can be directly on another element or there can be a middle element.When an element is considered "connected" to another element, it can be directly connected to another element or there can be a middle element.The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for illustrative purposes and do not represent the only implementation.

[0013] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs.The terms used in the specification of the utility model herein are only for the purpose of describing the specific implementation and are not intended to limit the utility model.The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0014] As Figs. 1-2As shown, a welding clamping device for engine cylinder head includes a rack 1, a crossbeam 2, a first station 3 and a second station 4, the crossbeam 2 is movably connected with the inner side wall of the rack 1, the first station 3 and the second station 4 are installed side by side on the crossbeam 2, the first station 3 and the second station 4 are rotatable, a partition beam 5 is installed between the first station 3 and the second station 4, and a limit sensor 51 for detecting the position of the workpiece is arranged on the partition beam 5. Specifically, the rack 1 adopts a triangular support frame, which has good stability and strong bearing capacity. The crossbeam 2 is installed on the top of the rack 1 and is used to support the first station 3 and the second station 4. The first station 3 and the second station 4 are rotatable on the crossbeam 2, which facilitates the welding robot to tilt the second station 4 or the first station 3 when welding the workpiece clamped on the first station 3 or the second station 4, so as to unload, re-clamp a new workpiece, and improve the production efficiency. Moreover, the first station 3 and the second station 4 are rotatable, and the welding robot does not need to be moved, only the welding mechanical arm needs to be rotated. The partition beam 5 is arranged between the first station 3 and the second station 4 to divide the stations, and the partition beam 5 is connected with the crossbeam 2 and does not rotate with the first station 3 or the second station 4. The limit sensor 51 is arranged on the partition beam 5 to detect whether the workpiece on the first station 3 or the second station 4 is installed in place.

[0015] As shown in Figs. 1-2 , the first station 3 and the second station 4 each include a cylinder clamp 31, a base 32, a rotating shaft 33, a workbench 34, a plurality of locking clamps 35 and a rotating motor 36. The cylinder clamp 31 is installed on the crossbeam 2, the base 32 is installed on the crossbeam 2, the rotating shaft 33 is movably connected with the base 32 at both ends, the workbench 34 is installed on the rotating shaft 33, the rotating motor 36 is arranged on the crossbeam 2, the output end of the rotating motor 36 is connected with the end of the rotating shaft 33 to drive the rotating shaft 33 to rotate, and a plurality of locking clamps 35 are installed on the tabletop of the workbench 34. Specifically, the cylinder clamp 31 is used to clamp the edge of the workpiece, and a plurality of locking clamps 35 arranged on the workbench 34 can be inserted into the holes of the workpiece to fix the position of the workpiece. A plurality of locking clamps 35 cooperate with the cylinder clamp 31 to securely lock the workpiece on the workbench 34. Due to the limitation of workshop space and cost, manual clamping and feeding are required. In order to facilitate manual clamping and feeding, the rotating motor 36 is used to drive the rotating shaft 33 to rotate, so that the workbench 34 can be tilted back and forth. When the workbench 34 is tilted to the feeding side, the worker can clamp or unclamp the workpiece. When the workbench 34 is tilted back to the horizontal position, the welding robot can perform welding operation.

[0016] As shown in Figs. 1-2 , the bottom of the rack 1 is provided with a pulley 11 to facilitate the movement of the entire clamping device and adjust the position of the clamping device under the lower end of the welding robot, making the use more flexible.

[0017] As Figs. 1-2 shown, the end of the crossbeam 2 is provided with a holding wheel 21, and the frame 1 is provided with a locker 12 for locking the holding wheel 21. Specifically, the locker 12 cooperates with the holding wheel 21, and the operation is extremely convenient, without using a bolt or other components to lock the crossbeam 2. When the locker 12 locks the holding wheel 21, the crossbeam 2 is locked and cannot rotate, fixing the initial position of the crossbeam 2, and when maintaining, the first station 3 and the second station 4 can be conveniently rotated as a whole.

[0018] The above-described embodiments only express several embodiments of the present application, and the description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the application.
