However, this technology requires die-casting of the positioning fixture before welding via the welding device, preventing simultaneous die-casting and welding, leading to low efficiency. Therefore, this technology still has room for improvement. Summary of the Invention

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fully automatic door handle laser welding machine, comprising a frame, a feeding mechanism, a discharging mechanism, a welding mechanism, and a pressing device. The pressing device includes a rotating base and a first rotating disk disposed on the upper end of the rotating base. Several tooling fixtures are mounted above the first rotating disk. A die-casting frame for mounting the pressing mechanism is disposed above the frame. A first pressing block for die-casting in cooperation with the tooling fixtures is disposed at the bottom of the pressing mechanism. The machine is characterized in that: a second rotating disk is disposed between the tooling fixtures and the first rotating disk, forming a travel cavity for mounting a reset device. The tooling fixtures can move axially above the second rotating disk via the reset device. A third rotating disk is disposed between the first pressing block and the pressing mechanism. A connecting structure is provided between the third rotating disk and the second rotating disk, allowing the second and third rotating disks to rotate synchronously when the third rotating disk presses down. The pressing mechanism is vertically provided with at least two third pressing blocks capable of pressing down the tooling fixtures to expose the processed product portion for welding.

[0006] By adopting the above technical solution, when a second rotary disk is provided at the bottom of the tooling fixture, the product can rotate during processing. At the same time, a stroke cavity is formed between the tooling fixture and the second rotary disk, and a reset device is installed in the stroke cavity. A third rotary disk is provided between the first pressure block and the pressing mechanism to give the first pressure block a rotation function. When the first pressure block is pressed down to the tooling fixture by the pressing mechanism, since the third rotary disk is connected to the second rotary disk through a connecting structure, and the setting of the third pressure block can expose the processed product part, the welding mechanism on the frame can directly complete the welding processing of the door handle during the die casting process through the synchronous rotation of the third rotary disk and the second rotary disk, which greatly saves the time of the original die casting and welding and improves the processing efficiency.

[0007] The aforementioned fully automatic door handle laser welding machine can be further configured such that: the tooling fixture includes a fixture plate disposed on the upper end of the second rotating disk, a second pressure block is provided on the top of the second rotating disk, a fixture hole is provided in the center of the fixture plate, the second pressure block is placed in the fixture hole, and the fixture hole and the second pressure block form a die casting groove for placing the product for die casting.

[0008] By adopting the above technical solution, a clamping plate is set on the upper end of the second rotating disk, and a clamping hole is opened in the center of the clamping plate, which together with the second pressure block forms a die-casting groove. This provides a stable and precise positioning for product placement and die casting, ensuring the stability and consistency of the product during the die-casting process. At the same time, the tight fit between the clamping hole and the second pressure block effectively prevents the product from moving or deforming during processing, further improving product quality and welding accuracy.

[0012] By adopting the above technical solution, a stable connection between the second rotating disk and the fixture disk is achieved by setting a fixed shaft on the second rotating disk and opening a through hole on the fixture disk. At the same time, the locking shaft on the third rotating disk is inserted and matched with the fixed shaft, ensuring that the second and third rotating disks can rotate synchronously when the third rotating disk is pressed down, thereby improving the stability and accuracy of the welding process.

[0022] By adopting the above technical solution, four clamping plates are distributed in a "+" shape on the top of the first rotating disk, which realizes the efficient coordination of the feeding, die casting and unloading processes. Each clamping plate is equipped with an unloading jaw, a feeding jaw and a first pressure block, which ensures the rapid conversion and precise positioning of the workpiece between different processes. This not only improves production efficiency, but also reduces the space occupied by the equipment, making the entire production process more compact and smooth.

[0023] The aforementioned fully automatic door handle laser welding machine can be further configured such that: the bottom of the third pressure block is provided with rollers.

[0024] The above technical solution, with rollers at the bottom of the third pressure block, improves the ease of operation and flexibility of the equipment. During the die casting process, the rollers can reduce the friction between the third pressure block and the workpiece, making the downward pressure more evenly distributed, thereby improving the processing accuracy and product quality.

[0025] The beneficial effects of this utility model are as follows: When the first pressure block is pressed down onto the tooling fixture by the pressing mechanism, the third rotating disk and the second rotating disk are connected by a connecting structure. At the same time, the setting of the third pressure block can expose the processed product part, which enables the welding mechanism on the frame to directly complete the welding processing of the door handle by the synchronous rotation of the third rotating disk and the second rotating disk during the die casting process, which greatly improves the work efficiency.
