Description

Technical Field

[0001] This utility model belongs to the field of laser welding machine technology, and specifically relates to a material pressing mechanism for a laser welding machine. Background Technology

[0002] In the processing of precision metal enclosures, laser welding machines can be used for the welding process. Laser welding machines use the high heat generated by a laser to melt the material and achieve welding between two objects.

[0003] Chinese patent application number 202420501704.6 discloses a pressing mechanism for a laser welding machine, comprising: a lifting module consisting of two sets of lifting components, each lifting component including a base plate, a cylinder disposed at the center of one side of the base plate, and a lifting plate disposed at the telescopic end of the cylinder; two sets of pressing rods detachably connected to the two sets of lifting plates, used to press the machine casing after the laser welding machine has been fed with material; and a buffer module consisting of two sets of buffer components, respectively disposed on the two sets of base plates and located below the corresponding lifting plates, used to mitigate the impact tendency of the pressing rods on the machine casing. In this pressing mechanism of the laser welding machine, when the pressing rods move downwards and press against the product, the lifting plate contacts the hydraulic buffer first. The hydraulic buffer suppresses the downward pressing tendency of the lifting plate when it presses down, thereby reducing the impact force of the pressing rods on the product, preventing damage to the product, and achieving product protection.

[0004] The aforementioned patents have the following drawbacks in use: the clamping component has a simple structure and cannot be adjusted, which limits its use; at the same time, the pressure rod has no buffer protection structure, which can easily cause damage to the material.

The slide rod 75 is connected in the middle of the vertical block 76, and the limiting slide 74 is connected at both ends of the slide rod 75. The crossbar 72 is connected between the limiting slide 74 and the moving assembly 71, and the clamping plate 73 is provided on the side of the crossbar 72.

[0023] By adopting the above technical solution, the moving component 71 drives the crossbar 72 to move, the crossbar 72 drives the clamping plate 73 to move, and the limiting slide block 74 slides on the slide bar 75, so that the clamping plates 73 move towards each other, clamping the two sides of the chassis product, restricting the movement of the product, ensuring that the welding process is completed smoothly. The spacing of the clamping plates 73 is adjustable, realizing the clamping of chassis of different sizes and expanding the processing range.

[0024] Specifically, the moving component 71 includes a moving base 711, a slide rail 712, a lead screw 713, and a dual-head motor 714.

[0027] By adopting the above technical solution, it is ensured that the rotation of the lead screw 713 drives the moving seat 711 to move in the slide rail 712.

[0028] In this embodiment, the lifting plate 3 is lifted by the cylinder 8, which in turn allows the buffer pressure rod 6 to press the product. When the buffer pressure rod 6 descends, the double-head motor 714 rotates, which drives the lead screw 713 to rotate. The lead screw 713 drives the moving seat 711 to move in the slide rail 712.

[0029] Example 2

The bottom of the connecting plate 4 is provided with a sleeve rod 61, and a plurality of buffer springs 64 are provided inside the sleeve rod 61.

[0036] The working principle and usage process of this utility model are as follows: When this utility model is in use, the lifting plate 3 completes the lifting action through the cylinder 8. The lifting plate 3 completes the lifting action through the cylinder 8, thereby allowing the buffer pressure rod 6 to complete the pressing work on the product. When the buffer pressure rod 6 descends, the rubber pad 63 contacts the surface of the machine box, the moving rod 62 is forcefully retracted into the sleeve rod 61, and the buffer spring 64 is compressed to buffer and achieve pressing protection.
