Description

Technical Field

[0001] The utility model belongs to the technical field of laser welding machines, and particularly relates to a high-stability anti-sputtering laser welding machine. Background Technique

[0002] Laser welding technology is widely used in many industrial fields such as electronics, automobiles, and aviation due to its advantages of high precision, high efficiency, and low deformation. As a flexible and convenient welding tool, a hand-held laser welding machine is particularly suitable for welding workpieces with small spaces and complex shapes. However, in actual operation, there are still some deficiencies in the stability and protection measures of the hand-held laser welding machine, which affect the welding quality and operation safety.

[0003] Most of the existing hand-held laser welding machines adopt a design with a single fixed grip. During long-term use by operators, fatigue is likely to occur, resulting in jitter during the welding process, which in turn affects the welding quality. Some hand-held laser welding machines are designed with protective devices to reduce the harm of welding spatter to operators. However, these protective devices are usually fixed structures and are difficult to adjust according to actual needs, unable to provide comprehensive and effective protection. Therefore, we designed a high-stability anti-sputtering laser welding machine to provide another technical solution for the above technical problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a high-stability anti-sputtering laser welding machine to solve the problems in the existing technology during use mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A high-stability anti-sputtering laser welding machine includes a laser welding device. On one side of the laser welding device, there is a welding gun. Outside the welding gun, there are two rotatable circular rings. At the bottom of the circular rings, there are fixed hand grips. Outside the hand grips, there are shock-absorbing rubber sleeves sleeved. Inside the hand grips, there is an adjusting mechanism for adjusting the rotation angle of the circular rings.

[0006] Preferably, the adjusting mechanism includes a vertical limiting column. The vertical limiting column is slidably connected inside the hand grip. Outside the vertical limiting column, there is a circular slider fixed. At the bottom of the circular slider and outside the vertical limiting column, there is a rigid spring. At the bottom of the vertical limiting column, there is a circular pulling block fixed. On the outside of the circular pulling block, there are anti-slip patterns.

[0007] Preferably, a vertical sliding groove is opened inside the hand grip. The circular slider is located inside the vertical sliding groove and is slidably connected with the hand grip through the vertical sliding groove.

[0008] Preferably, a plurality of rectangular bars are fixed on the outer side of the hand-held grip. Rectangular grooves are formed inside the shock-absorbing rubber sleeve. The hand-held grip and the shock-absorbing rubber sleeve are slidably connected through the cooperation of the rectangular bars and the rectangular grooves.

[0009] Preferably, a circular fixed ring is rotatably connected inside the circular collar. The circular fixed ring is sleeved on the outer side of the welding gun and fixedly connected to the welding gun. A circular limiting hole adapted to the hand-held grip is formed inside the circular fixed ring.

[0010] Preferably, a plurality of transverse tubes are uniformly fixed at one end of one of the circular collars. A transverse optical rod is slidably connected inside the transverse tube. One end of the transverse optical rod away from the transverse tube is fixed with a circular moving ring. A vertical protection plate is arranged at the bottom of the circular moving ring. The vertical protection plate and the circular moving ring are connected by a fixing bolt.

Specific implementation mode

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Refer to Figure 1-7 , a highly stable anti-sputtering laser welding machine, including a laser welding device 1, a welding gun 2 is arranged on one side of the laser welding device 1, two rotatable circular collars 5 are arranged on the outer side of the welding gun 2, a hand-held grip 3 is fixed at the bottom of the circular collar 5, a shock-absorbing rubber sleeve 4 is sleeved on the outer side of the hand-held grip 3, and an adjusting mechanism for adjusting the rotation angle of the circular collar 5 is arranged inside the hand-held grip 3;

[0024] The adjusting mechanism includes a vertical limiting column 9, the vertical limiting column 9 is slidably connected inside the hand-held grip 3, a circular slider 10 is fixed on the outer side of the vertical limiting column 9, a rigid spring 11 is arranged at the bottom of the circular slider 10 and on the outer side of the vertical limiting column 9, and a circular pulling block 12 is fixed at the bottom of the vertical limiting column 9;

[0025] A vertical sliding groove is opened inside the hand-held grip 3, the circular slider 10 is located inside the vertical sliding groove and is slidably connected with the hand-held grip 3 through the vertical sliding groove. Through the arrangement of the vertical sliding groove, the circular slider 10 can slide vertically inside the hand-held grip 3, so that the moving track of the circular slider 10 can be guided;

[0026] A plurality of rectangular strips are fixed on the outer side of the hand-held grip 3, rectangular grooves are opened inside the shock-absorbing rubber sleeve 4, and the hand-held grip 3 and the shock-absorbing rubber sleeve 4 are slidably connected through the cooperation of the rectangular strips and the rectangular grooves. Through the arrangement of the rectangular strips and the rectangular grooves, the shock-absorbing rubber sleeve 4 can slide vertically on the outer side of the hand-held grip 3;

[0027] Anti-slip lines are opened on the outer side of the circular pulling block 12. Through the arrangement of the anti-slip lines, the anti-slip performance of the circular pulling block 12 is improved, so as to facilitate the pulling of the circular pulling block 12;

[0028] A circular fixing ring 8 is rotatably connected inside the circular sleeve ring 5. The circular fixing ring 8 is sleeved outside the welding gun 2 and fixedly connected to the welding gun 2, enabling the circular sleeve ring 5 to rotate outside the circular fixing ring 8. A circular limiting hole adapted to the hand-held grip 3 is provided inside the circular fixing ring 8. Through the setting of the circular limiting hole, the hand-held grip 3 can enter the inside of the circular fixing ring 8, thereby restricting the rotation of the hand-held grip 3.

[0029] Here, by pulling the circular pull block 12 in a direction away from the circular sleeve ring 5, the pulling of the circular pull block 12 enables the vertical limiting post 9 to slide vertically inside the hand-held grip 3, thereby enabling the hand-held grip 3 to move out of the inside of the circular fixing ring 8, enabling the circular sleeve ring 5 to slide outside the circular fixing ring 8. The movement of the circular slider 10 causes the rigid spring 11 to deform under force, and the rotation of the circular sleeve ring 5 enables the angle of the hand-held grip 3 to be adjusted.

[0030] A plurality of transverse tubes 14 are uniformly fixed at one end of one of the circular sleeve rings 5. A transverse optical rod 15 is slidably connected inside the transverse tube 14. The end of the transverse optical rod 15 away from the transverse tube 14 is fixed with a circular moving ring 6. A vertical protection plate 7 is provided at the bottom of the circular moving ring 6. The vertical protection plate 7 is connected to the circular moving ring 6 through a fixing bolt 13.

[0031] A circular through groove is provided inside the circular moving ring 6. The circular moving ring 6 is sleeved outside the welding gun 2 and is slidably connected to the welding gun 2 through the circular through groove. Through the setting of the circular through groove, the circular moving ring 6 can slide outside the welding gun 2, thereby enabling the vertical protection plate 7 to move at one end of the hand-held grip 3.

[0032] Here, when the circular sleeve ring 5 rotates, through the setting of the transverse tube 14 and the transverse optical rod 15, the circular moving ring 6 can rotate outside the welding gun 2, thereby enabling the vertical protection plate 7 to rotate following the hand-held grip 3, enabling the vertical protection plate 7 to block the hand outside the hand-held grip 3, preventing the sputtering of sparks onto the hand and preventing hand injuries. Through the setting of the transverse optical rod 15 and the transverse tube 14, the circular moving ring 6 can slide outside the welding gun 2, so that the vertical protection plate 7 can adjust the distance between the hand-held grip 3 and the vertical protection plate 7 according to the usage requirements.

[0033] Working principle: Pull the circular pull block 12 away from the circular collar 5. The pulling of the circular pull block 12 enables the vertical limiting post 9 to slide vertically inside the handgrip 3, thereby enabling the handgrip 3 to move out of the inside of the circular fixing ring 8, allowing the circular collar 5 to slide outside the circular fixing ring 8. The movement of the circular slider 10 causes the rigid spring 11 to deform under force. The rotation of the circular collar 5 enables the angle of the handgrip 3 to be adjusted;

[0034] When the circular collar 5 rotates, through the arrangement of the transverse tube 14 and the transverse optical rod 15, the circular moving ring 6 can rotate outside the welding gun 2, and thus the vertical protection plate 7 can rotate following the handgrip 3, enabling the vertical protection plate 7 to shield the hand outside the handgrip 3, preventing the sputtering of sparks onto the hand and preventing hand injuries. Through the arrangement of the transverse optical rod 15 and the transverse tube 14, the circular moving ring 6 can slide outside the welding gun 2, so that the vertical protection plate 7 can adjust the distance between the handgrip 3 and the vertical protection plate 7 according to the usage requirements.
