Example

[0024] refer to Figure 1-4The shown embodiment shows a lifting welding mechanism for a welding unit, comprising a bracket 1 and a welding assembly 7. An adjustment mechanism 3 is slidably connected to the bracket 1, and the welding assembly 7 is connected to the bracket 1 through the adjustment mechanism 3. The bracket 1 is mounted on a hydraulic lifting rod 6, and a winding mechanism 2 for winding the welding machine signal line is also provided at the rear of the bracket 1.

[0025] As an implementation method in this embodiment, the height of the bracket 1 can be adjusted by setting a hydraulic lifting rod 6, and in order to enable the welding assembly 7 to be adjusted laterally left and right, the adjustment mechanism 3 also includes a lateral adjustment assembly 4, and a frame 41 is set in the lateral adjustment assembly 4. The frame 41 is a rectangular shell that is transparent on the left and right, and is slidably connected to the bracket 1. The frame 41 is equipped with a traveling gear 42 through a bearing seat, and the traveling gear 42 is engaged with a connecting gear, which is connected to the output end of the first drive motor 43. The first drive motor 43 is installed on the top surface of the frame 41. A slide groove is also provided on the bracket 1, and a tooth groove matching the gear is provided in the slide groove, and the traveling gear 42 is engaged on the tooth groove.

[0026] As an implementation method in this embodiment, in order to enable the welding assembly 7 to be longitudinally adjusted in the front and rear directions, a longitudinal adjustment assembly 5 is further provided under the frame 41. The connecting block 51 in the longitudinal adjustment assembly 5 is connected to the bottom surface of the frame 41. The connecting block 51 is connected to the adjustment rod 52 through the bearing seat. The adjustment rod 52 is provided with a second tooth groove at its three-point dividing line. At the same time, the adjustment rod 52 is divided into a long rod 54 and a short rod 55. A transmission gear 56 is engaged in the second tooth groove. The transmission gear 56 is installed on the output end of the second drive motor 53. A threaded section is provided on the long rod 54 and the short rod 55. The two sets of screws The threads rotate in opposite directions, and the thread pitch of the thread segment on the long rod 54 is greater than the thread pitch of the thread segment on the short rod 55. The welding assembly 7 is arranged on the long rod 54. The slider 71 in the welding assembly 7 is provided with a first threaded hole that is compatible with the thread segment on the long rod 54. The short rod 55 is provided with a counterweight block 8. The counterweight block 8 is provided with a second threaded hole that is compatible with the thread segment on the short rod 55. The slider 71 and the counterweight block 8 are connected to the frame 41 respectively through the first limiting rod 57 and the second limiting rod 58. The slider 71 slides on the first limiting rod 57, and the counterweight block 8 slides on the second limiting rod 58.

[0027] As an implementation method in this embodiment, in order to prevent the laser signal line of the welding machine from being entangled or stuck in the gap of the equipment during operation, the welding assembly 7 also includes a fixed rod 72 and a limit ring 73. The slider 71 is connected to the welding head through the fixed rod 72. The limit ring 73 is provided in multiple groups and is respectively arranged on the connecting block 51 and the counterweight block 8. The limit ring 73 corresponds to the position of the welding head. The winding mechanism 2 also includes a base 21 and a winding disk 22. The winding disk 22 is rotatably connected to the base 21 through a rotating shaft 24. A reset spring 23 is also provided in the base 21, and the rotating shaft 24 passes through the base 21 and is connected to the reset spring 23.

[0028] The working principle of this utility model is as follows: before starting work, the laser signal line of the welding machine is first passed through each limiting ring 73 in turn and then connected to the welding head, and then the remaining laser signal line is wound onto the winding disk 22 in the winding mechanism 2, so that when adjusting the position of the welding component 7, the limiting ring 73 prevents the laser signal line from being stuck in the gap of the equipment, and the winding mechanism 2 allows the welding component 7 to be easily pulled out when it is away from the winding disk 22. When the welding component 7 approaches the winding disk 22, under the action of the reset spring 23 in the base 21, the reset spring 23 drives the winding disk 22 to rotate through the rotating shaft 24, and winds up the laser signal line to prevent the laser signal line from being stuck in the gap. Then, according to the required welding position, the height of the hydraulic lifting rod 6 adjustment bracket 1 is adjusted to control the operation of the first drive motor 43, and the connecting gear on the output end of the first drive motor 43 drives the travel gear 42 to rotate, so that the travel gear 42 moves in the slide groove on the bracket 1, and through the meshing relationship between the walking gear 42 and the first tooth groove in the slide groove on the bracket 1, the lateral adjustment component 4 is moved to the required position on the bracket 1 under the action of the first drive motor 43, and then by driving the second drive motor 53, the second drive motor 53 drives the adjusting rod 52 engaged with it to rotate through the transmission gear 56, and the long rod 54 and the short rod 55 in the adjusting rod 52 rotate synchronously, so that the welding assembly 7 engaged on the long rod 54 moves to the required position along the first limit rod 57. At the same time, because the thread pitches of the threaded segments on the long rod 54 and the short rod 55 are different, the counterweight block 8 moves a shorter distance on the short rod 55 when moving along the second limit rod 58, avoiding the problem of equipment tilting due to the counterweight. After that, the welding machine can be started, and the product of the welding head connected to the slider 71 by the fixed rod 72 through the welding assembly 7 is processed.
