Description

Technical Field

[0001] The utility model relates to the technical field of copper sheet welding, in particular to a clamping mechanism for copper sheets of a welding machine. Background Art

[0002] Copper sheet welding is usually done by arc welding or spot welding. Arc welding requires the use of electrodes suitable for copper materials, while spot welding uses electric current to weld copper sheets together. When welding copper sheets, appropriate welding processes and parameters are required to ensure welding quality and stability. The existing copper sheet welding process has at least the following disadvantages: In the existing copper sheet welding, most people manually pinch the copper sheet with their fingers and then control the electric welder to weld the copper sheet. This method requires personnel to maintain high hand stability during welding, and after welding multiple copper sheets, the staff are prone to hand soreness, which causes discomfort to the personnel. Therefore, we have introduced a clamping mechanism for the copper sheet of the welding machine. Utility Model Content

For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0022] See also Figure 1-4 , the utility model provides a technical solution:

[0023] A clamping mechanism for a copper sheet of a welding machine includes a base 1, and the front and rear ends of the base 1 are fixedly connected to several support plates 7, and the several support plates 7 are all narrow at the top and wide at the bottom. A No. 1 slide groove 8 is opened in the middle of the upper end of the base 1, and a No. 2 lifting frame 6 is slidably connected to the left part of the No. 1 slide groove 8, and a No. 1 lifting frame 2 is slidably connected to the right part of the No. 1 slide groove 8. The No. 2 lifting frame 6 and the No. 1 lifting frame 2 are both "T"-shaped structures. A No. 1 clamping device 3 is fixedly connected to the upper end of the No. 1 lifting frame 2, and a No. 2 clamping device 5 is fixedly connected to the upper end of the No. 2 lifting frame 6. The No. 2 clamping device 5 and the No. 1 clamping device 3 have the same structure, and a copper sheet body 4 is placed between the No. 2 lifting frame 6 and the No. 1 lifting frame 2.

[0024] In this embodiment, the No. 2 clamping device 5 includes a bracket 51, which is an "L"-shaped structure. The rear end of the bracket 51 is provided with a No. 2 slide groove 54 that passes through the front and back. A slider 52 is slidably connected in the No. 2 slide groove 54, and the front end of the slider 52 is fixedly connected to a clamping plate 53. The upper end of the clamping plate 53 is movably connected to a threaded rod 56 through a bearing, and the upper end of the threaded rod 56 is fixedly connected to a knob 55, and the threaded rod 56 is threadedly connected to the bracket 51; the bracket 51 is fixedly connected to the No. 2 lifting frame 6; a circular groove 61 is provided in the middle of the right end of the No. 1 lifting frame 2 and the middle of the right end of the No. 2 lifting frame 6, and a threaded groove 62 is provided in the lower part of the right end of the No. 1 lifting frame 2 and the lower part of the right end of the No. 2 lifting frame 6. Due to the limiting effect of the slider 52, the clamping plate 53 can only move up and down, thereby improving stability.

[0025] In this embodiment, the right end of the base 1 is fixedly connected to the motor 11, the output end of the motor 11 is fixedly connected to the bidirectional screw 12, and the base 1 is fixedly connected to the positioning rod 13, which is located on the upper part of the bidirectional screw 12; the left part of the outer surface of the bidirectional screw 12 is threadedly connected to the No. 2 lifting frame 6, and the right part of the outer surface of the bidirectional screw 12 is threadedly connected to the No. 1 lifting frame 2, and the positioning rod 13 is interlaced and movably connected with the No. 2 lifting frame 6 and the No. 1 lifting frame 2.

[0026] It should be noted that the utility model is a clamping mechanism for a copper sheet of a welding machine. During use, the motor 11 is first started through an external control system. After the motor 11 works, it drives the bidirectional screw 12 to rotate. Under the action of the bidirectional screw 12 and the positioning rod 13, the No. 1 lifting frame 2 and the No. 2 lifting frame 6 are close to each other for position adjustment, which is convenient for adapting to the clamping of copper sheets of different lengths and improves applicability. After adjusting to the appropriate position, the copper sheet body 4 is placed on the No. 2 lifting frame 6 and the upper end of the No. 1 lifting frame 2. At this time, the knob 55 is rotated to drive the threaded rod 56 to rotate. During the rotation of the threaded rod 56, the clamping plate 53 will move downward, and the copper sheet body 4 will be clamped under the cooperation of the clamping plate 53 and the No. 2 lifting frame 6. Then, the No. 1 clamping device 3 is operated by this method to clamp the copper sheet body 4, thereby avoiding the increase of workload of personnel pinching the copper sheet body 4, and also improving the stability of the clamping of the copper sheet body 4, avoiding shaking and displacement of the copper sheet body 4.
