Technical Field

[0002] At present, double-layer stainless steel cups are made by welding the inner liner and the outer shell at the mouth of the cup. The existing inner liner and the outer shell both have straight mouths, and the inner liner and the outer shell mouth size accuracy is required to be high during welding. If there is a slight roundness loss in the metalworking process, the mouth will be too tight to fit, deformed, etc. Therefore, there is a mouth matching process in the production process to make the inner liner and the outer shell mouth size meet the welding requirements.

[0003] A Chinese invention patent (CN114833447A) discloses a multi-purpose welding device for a double-layer stainless steel thermos cup. The device has two groups of workstations and can process cups at two workstations simultaneously during use, thereby improving work efficiency.

[0004] However, in actual use, the two sets of laser welding head equipment are independent of each other. When the product to be processed changes, the positions of the two sets of laser welding heads and their welding angles need to be adjusted separately, which is troublesome to adjust and affects production efficiency.

[0085] A plurality of welding positioning mechanisms, the welding positioning mechanisms comprising a cup bottom positioning member 2, a guide frame 3 and a laser welding head 4;

[0086] The cup bottom positioning member 2 is vertically inserted into the avoidance strip hole 11;

[0087] The guide frame 3 is vertically fixedly mounted on the mounting plate 1;

[0088] A sliding member is installed on the laser welding head 4, and the sliding member is slidably installed in the guide frame 3;

[0089] A synchronous connection mechanism 5, which is installed on the sliding member and is used to drive the sliding member to rotate synchronously;

[0090] The second adjustment mechanism is installed on the mounting plate 1 and is drivingly connected to one of the sliding members, and is used to adjust the position of the sliding member on the guide frame 3, thereby changing the inclination angle of the laser welding head 4 on the vertical plane.

[0091] It also includes a fixed bracket, and the mounting plate 1 is installed on the fixed bracket in a transverse sliding manner;

[0092] The first adjusting mechanism is fixedly mounted on the fixing bracket and is drivingly connected to the mounting plate 1 , and is used for adjusting the position of the mounting plate 1 relative to the fixing bracket.

[0093] The first adjusting mechanism drives the mounting plate 1 to move laterally relative to the cup bottom positioning member 2, thereby achieving the purpose of driving all laser welding heads 4 to move laterally synchronously, and the adjustment is simple.

[0094] A plurality of slide rails 101 are transversely mounted on the fixed bracket, a plurality of sliders 102 are fixedly mounted on the mounting plate 1 , and the sliders 102 are slidably mounted on the slide rails 101 .

[0095] In fact, according to actual conditions, a guide rod can be set on the fixed bracket to pass the mounting plate 1 through the guide rod to achieve horizontal sliding installation. This embodiment completes the horizontal sliding installation between the mounting plate 1 and the fixed bracket through the cooperation of the slide rail 101 and the slider 102, and has a simple structure and strong stability.

[0098] In fact, according to actual conditions, it is also possible to select the mutual cooperation of gears and racks, and then use a turntable to rotate the gears, and use the meshing of the gears and racks to drive the racks to move, thereby realizing the adjustment of the position of the mounting plate 1. In this embodiment, a first adjustment mechanism is formed by a first servo motor 21, a first screw rod and a first nut seat. The mutual cooperation of the screw rod and the nut seat makes the first adjustment mechanism have a higher adjustment accuracy and a self-locking performance. The servo motor realizes the automation of the adjustment, which is easy to operate and has strong practicality.

[0099] The guide frame 3 includes an arc track 31 , and the center of the arc track 31 coincides with the welding point of the laser welding head 4 .

[0100] The sliding member is slidably installed in the arc track 31 .

[0101] In fact, according to actual conditions, a connecting rod structure can be selected as the guide frame 3 to ensure the inclination of the laser welding head 4. In this embodiment, the sliding trajectory of the sliding part is limited by an arc track 31 whose center coincides with the welding point of the laser welding head 4, so that when the laser welding head 4 is adjusted by the second adjustment mechanism, the welding point of the laser welding head 4 does not change in horizontal height, but only changes its own inclination angle on the vertical plane, that is, the inclination angle of the laser welding head 4 on the vertical plane, which is more convenient to adjust.

[0102] The sliding member includes a connecting plate 41, a sub-plate 42 and at least two rollers 410, preferably two;

[0103] The connecting plate 41 is fixedly connected to the laser welding head 4, and the roller 410 is rotatably installed between the connecting plate 41 and the auxiliary plate 42 and is located in the arc track 31;

[0104] The second adjusting mechanism is transmission connected to the auxiliary plate 42 .

[0105] In fact, according to actual conditions, it is also possible to directly select an arc-shaped slider that matches the arc track 31 as a sliding part connected to the laser welding head 4 to achieve the purpose of not changing the horizontal height of the welding point of the laser welding head 4 and only changing the inclination angle of the laser welding head 4 on the vertical plane. In this embodiment, the arc track 31 is clamped by the connecting plate 41 and the sub-plate 42 to limit the axial movement freedom of the sliding part along the roller 410, and then the setting of no less than two rollers 410 in the arc track 31 is realized to limit the deflection angle of the sliding part when it moves, thereby achieving the purpose of not changing the horizontal height of the welding point of the laser welding head 4 and only changing the inclination angle of the laser welding head 4 on the vertical plane. The structure is simple and practical.

[0106] The sliding member also includes a fixing sleeve 43 and a connecting shaft 44;

[0110] In fact, according to actual conditions, it is also possible to choose to set a ring at the free end of the second adjusting mechanism, set a sleeve rod on the sub-plate 42, and realize the formation of freedom by setting the ring on the sleeve rod. In this embodiment, the fixed sleeve 43 and the connecting shaft 44 cooperate with each other. On the basis of realizing the transmission connection between the second adjusting mechanism and the sub-plate 42, the rotational freedom between the connecting shaft 44 and the fixed sleeve 43 is utilized to avoid the transmission connection between the second adjusting mechanism and the sub-plate 42, and limit the sliding of the sliding part along the arc track 31. The practicality is strong.

[0114] In fact, according to actual conditions, a telescopic hydraulic cylinder can be selected as the second adjusting mechanism. In this embodiment, the second adjusting mechanism is composed of a second servo motor 22, a second screw rod 220 and a second nut seat. The second adjusting mechanism has a higher adjustment accuracy by utilizing the mutual cooperation between the screw rod and the nut seat. At the same time, it also has a self-locking performance.

The structure is simple, the installation is convenient, and the practicability is strong.

[0117] A support block is provided between the auxiliary plate 42 and the connecting plate 41. The distance between the auxiliary plate 42 and the connecting plate 41 is limited by the support block, so as to avoid the problem that the auxiliary plate 42 and the connecting plate 41 are over-squeezed when the fixing bolts 431 are over-tightened, and the roller 410 cannot be rotated, which is more practical.
