Description

Technical Field

[0001] This utility model relates to the field of laser welding technology, specifically to an automatic limiting laser welding machine feeding structure. Background Technology

[0002] Laser welding is a welding method that uses a focused laser beam to bombard the workpiece, generating heat to weld components. Due to the optical properties of lasers, such as refraction and focusing, laser welding is ideal for welding miniature parts and areas with poor accessibility. Laser welding also features low heat input, minimal weld deformation, and is unaffected by electromagnetic fields.

[0003] Laser welding machines require a feeding structure during operation. Existing feeding structures cannot automatically limit the positioning of the welded parts after placement, requiring manual operation, which is time-consuming. Therefore, to solve this problem, we propose an automatic limiting feeding structure for laser welding machines. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic limiting feeding structure for a laser welding machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

Each feeding component includes a front U-shaped frame and a rear U-shaped frame. Movable slots are opened through the top of both ends of the inner wall of the rear U-shaped frame. Movable blocks are slidably arranged on the opposite sides of the inner walls of the two movable slots. T-shaped plates are connected to the adjacent ends of the two movable blocks, and sliding plates are connected to the opposite ends of the two movable blocks. Upper support plates are connected to the top of both sides of the front U-shaped frame, and lower support plates are connected to the bottom of both sides of the front U-shaped frame. A drive motor is connected to the bottom of one of the lower support plates, and a transmission shaft is connected to the output end of the drive motor. The top of the transmission shaft passes through both the lower and upper support plates. A second transmission shaft passes through the other lower and upper support plates. A drive wheel is fixedly sleeved on the outside of the first transmission shaft, and a driven wheel is fixedly sleeved on the outside of the second transmission shaft.

[0007] Preferably, mounting holes are provided at all four corners of the top of the base, and several support plates are connected to the bottom of the front U-shaped frame and the bottom of the rear U-shaped frame, with the bottom of the support plates connected to the top of the base.

[0008] Preferably, the ends of the two T-shaped plates that are far apart slide in contact with the inner wall of the rear U-shaped frame, and the ends of the two sliding plates that are opposite each other slide in contact with both ends of the rear U-shaped frame.

[0009] Preferably, the external parts of the first and second drive shafts are movably connected to the lower and upper support plates via bearings.

[0010] Preferably, the drive wheel and the driven wheel are both fitted with a transmission belt. The two ends of the transmission belt that are far apart are connected to a connecting plate by bolts. A bearing block is connected to the top of the connecting plate. A vertical plate is connected to the top of one of the bearing blocks and one of the sliding plates. An electric telescopic plate is connected to the top of the other bearing block and the other sliding plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention utilizes a feeding component, vertical plate, placement groove, pressure sensor, placement plate, electric telescopic plate, clamping plate, storage slot, electric telescopic rod, and hidden hole. After welding, the component to be welded in the left placement groove is removed, and the component to be welded is placed in the right placement groove. The pressure sensor on the right detects the presence of the component to be welded, and the two electric telescopic rods on the right extend, causing the two clamping plates on the right to extend and clamp the component to be welded.
