Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a clamping device for steel plate welding. Background Art

[0002] Welding is a process in which two or more materials of the same or different types are connected into one by bonding and diffusion between atoms or molecules. Steel plates are flat steel materials that are cast by molten steel and pressed after cooling. They are flat and rectangular and can be directly rolled or cut from wide steel strips.

[0003] In the production and processing of steel components, it is usually necessary to weld steel plates. During welding, the operator usually needs to support one of the steel plates with one hand and hold the welding gun with the other hand to perform welding operations. However, the steel plate may be shaken in the process of supporting the steel plate with the hand, making it difficult to effectively fix the steel plate, thereby affecting the quality of welding. In order to address this technical problem, a clamping device for steel plate welding is proposed herein. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 The clamping device for steel plate welding comprises a crossbeam 1, which can be installed on the top of the wall of a processing workshop with the help of components such as cement nails.

[0023] A double-headed screw 2 is provided on the crossbeam 1 and is rotated by an adjusting motor 3. The output shaft of the adjusting motor 3 is connected to one end of the double-headed screw 2. Nuts 4 are threadedly sleeved on the outer walls of both ends of the double-headed screw 2. A mounting frame 5 is fixed on the nut 4. The mounting frame 5 and the nut 4 are welded together. A rotating ring 7 is provided on the mounting frame 5 through a limiting mechanism. Two mounting blocks 12 are provided on the rotating ring 7. A clamping frame 14 is provided on the mounting block 12 through a cylinder 13. A transmission shaft 10 is provided on the crossbeam 1 and is rotated by a rotating motor 11. The transmission shaft 10 is connected to the rotating ring 7 through a rotating mechanism.

[0024] The limiting mechanism includes a bolt 6 threadedly mounted on the mounting frame 5, a limiting block is provided on the end of the bolt 6, and an annular groove 8 corresponding to the limiting block is provided on the outer walls on both sides of the rotating ring 7. The bolt 6 is installed on the mounting frame 5 and the limiting block is in the annular groove 8, so the rotating ring 7 can be in the mounting frame 5 without being separated and can rotate. Correspondingly, after removing the bolt 6, the rotating ring 7 can be released from the mounting frame 5 for convenient disassembly, thereby facilitating the inspection and maintenance of components such as the cylinder 13.

[0025] The rotating mechanism includes a driving gear 16 arranged in the mounting frame 5, and the driving gear 16 is slidably sleeved on the outside of the transmission shaft 10. A ring gear 9 is provided on the arc-shaped outer wall of the rotating ring 7, and the ring gear 9 is meshed with the driving gear 16. When the driving gear 16 rotates, the driving gear 16 can drive the rotating ring 7 to rotate with the help of the ring gear 9.

[0026] A limit rod 15 is fixedly provided on the cross beam 1 , the limit rod 15 is parallel to the double-headed screw 2 , and the limit rod 15 slides through the nut 4 , and the limit rod 15 limits the nut 4 , thereby preventing the nut 4 from rotating together with the double-headed screw 2 .

[0027] The mounting frame 5 is designed in an inverted U shape, and the outer walls on both sides of the driving gear 16 are in sliding contact with the inner wall of the mounting frame 5. The driving gear 16 cannot move horizontally in the mounting frame 5, and cannot move vertically under the action of the transmission shaft 10.

[0028] The transmission shaft 10 is in a regular hexagonal shape in vertical section. The mounting frame 5 is provided with a through circular hole through which the transmission shaft 10 passes. The diameter of the through circular hole is larger than the diameter of the circumscribed circle of the transmission shaft 10. The regular hexagonal structure can synchronously drive the driving gear 16 to rotate when the transmission shaft 10 rotates, and will not affect the movement of the mounting frame 5 and other components relative to the transmission shaft 10.

[0029] When the utility model is used, two steel plates are placed in two rotating rings 7, each steel plate is clamped by two clamping frames 14, and adjusted by cylinders 13 to adapt to steel plates of different widths, such as Figure 1In the state shown, the steel plate is in a horizontal state after being clamped and fixed. If the adjusting motor 3 is started, it can drive the double-headed screw 2 to rotate. When the double-headed screw 2 rotates, the nut 4 on its outer wall will drive the two steel plates closer with the help of the mounting frame 5 and other components, and the ends of the two steel plates will contact to perform welding operations. If the rotating motor 11 is started, the rotating motor 11 can drive the driving gear 16 to rotate with the help of the transmission shaft 10, and the driving gear 16 can drive the rotating ring 7 to rotate with the help of the gear ring 9, thereby realizing the rotation and flipping operation of the steel plate and realizing the double-sided welding operation.

[0030] In this solution, if the bolt 6 is rotated, it can be disengaged from the mounting frame 5, and at the same time, the limit block is driven to disengage from the annular groove 8, and the installation of the rotating ring 7 relative to the mounting frame 5 is immediately released, thereby realizing the disassembly of components such as the cylinder 13. Removing the above components and placing them on the ground or a workbench also facilitates inspection, maintenance or replacement.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
