Technical Field

[0001] The utility model relates to the field of welding equipment, in particular to a welding head with a universal power-assisting arm. Background Art

[0002] A laser welding head is a key component that uses a laser beam as a heat source to excite the active medium of the laser head in a specific way, oscillating back and forth in the resonant cavity to form an excitation radiation beam, thereby achieving efficient and precise welding. It is mainly used for welding metals, especially thin-walled materials and precision parts, and has the advantages of fast welding speed, high weld quality, small heat-affected zone, and small deformation.

[0003] At present, in order to save the physical strength of the workers, welding is often performed by using a power-assisting arm to clamp the handheld welding head. However, in actual use, since the flexibility of the power-assisting arm when clamping the handheld welding head is not as fast as the manual handheld welding head, it may happen that during the work process, the workers need to remove the welding head from the place where the power-assisting arm clamps it for some special welding positions, such as narrow spaces and complex curved surfaces, and then use the staff to hold the welding head to perform welding.

[0004] At present, in order to ensure that the assist arm and the welding head are directly and firmly fixed so as not to loosen or fall off during the welding process, the assist arm and the welding head are often fixed with bolts. However, when the staff needs to separate the assist arm from the welding head, the bolts may fall off and the installation may be troublesome. Therefore, a welding head with a universal assist arm is proposed to solve the above problems. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1The utility model provides an embodiment: a welding head with a universal power-assisting arm, comprising a base 1 and a laser welding head 2. The base 1 is used to connect to the surface of the laser welding table. The top of the base 1 is fixedly connected to a power-assisting arm body 3. The connection port of the power-assisting arm body 3 can freely change the moving position. This technology is a prior art and can be implemented by technicians in this field, so it will not be described in detail in this case. By setting the power-assisting arm, it is ensured that the moving position of the laser welding table can present circular, filled, and rectangular modes, thereby realizing multifunctional welding.

[0032] Reference Figure 1 、 Figure 3 and Figure 4 The connection port of the power-assisting arm body 3 is connected to the laser welding head 2 through a fixing component 4. The fixing component 4 includes a mounting seat 41. The outer wall of the mounting seat 41 is fixedly connected to the connection port of the power-assisting arm body 3. The mounting seat 41 is L-shaped, and a plurality of support rods are provided on the inner side of the mounting seat 41. Through the setting of the support rods, the overall side view of the mounting seat 41 is triangular, thereby increasing the load-bearing capacity and stability of the mounting seat 41. A mounting ring 42 is fixedly connected to the top of the mounting seat 41. The shape of the mounting ring 42 is composed of an upper ring and a lower cylinder. Through the cylindrical setting below the mounting ring 42, it is ensured that the contact surface between the mounting ring 42 and the mounting seat 41 is larger, thereby ensuring that the mounting ring 42 is more stable than when the cylindrical area is not provided.

[0033] Reference Figure 2 - Figure 4 , a sliding groove 43 is provided on the inner wall of the mounting ring 42, and a fixed block 44 is slidably connected to the inner wall of the sliding groove 43. The shape of the fixed block 44 is a shape formed by connecting a cylinder and a hemisphere, and the circular surface of the cylindrical part of the fixed block 44 is the same size as the circular surface of the hemisphere. The end of the fixed block 44 away from the middle of the mounting ring 42 is elastically connected to the inner wall of the sliding groove 43 by a spring 45. When the spring 45 is at its original length, only the cylindrical part of the fixed block 44 is inside the sliding groove 43, and the hemispherical part of the fixed block 44 is at the middle opening of the mounting ring 42. The rear end of the laser welding head 2 is fixed A connecting plate 47 is connected, and the size of the connecting plate 47 in the top view is consistent with the size of the mounting seat 41 in the top view. The bottom end of the connecting plate 47 is fixedly connected to a mounting column 48, and the outer wall size of the mounting column 48 matches the size of the hole opened in the middle of the mounting ring 42. A connecting hole 49 is opened on the side wall of the mounting column 48, and the shape of the connecting hole 49 matches the shape of the fixed block 44. The height of the mounting column 48 is consistent with the height of the annular part of the mounting ring 42. Through the consistent height setting, it is ensured that when the mounting column 48 enters the mounting ring 42, the bottom surface of the connecting plate 47 can just contact the top of the mounting ring 42, thereby increasing stability.

[0034] Reference Figure 2- Figure 4 , a control assembly 5 is provided inside the mounting ring 42, and the control assembly 5 includes a rotating groove 51, which is opened on the inner wall of the mounting ring 42 below the sliding groove 43. The inner wall of the rotating groove 51 is rotatably connected with a rotating ring 52, which is in the shape of a circular ring. A sliding groove 53 is opened on the top of the rotating ring 52, which is in the shape of an arc, and the width of the sliding groove 53 matches the diameter of the L-shaped rod 54. The inner wall of the mounting ring 42 is slidably connected with the L-shaped rod 54. When the L-shaped rod 54 is at the position farthest from the fixed block 44, the L-shaped rod The distance between 54 and the fixed block 44 is greater than the radius of the hemispherical part of the fixed block 44. The bottom end of the L-shaped rod 54 is arranged inside the sliding groove 53. The inner wall of the mounting ring 42 between the rotating groove 51 and the sliding groove 43 is provided with a hole that matches the sliding path of the L-shaped rod 54. The inner wall of the mounting ring 42 is provided with a concave groove 55. The outer wall of the rotating ring 52 is slidably connected with a control rod 56. The control rod 56 is arranged inside the concave groove 55. The sliding direction of the control rod 56 is up and down. The diameter of the control rod 56 matches the width of the concave groove 55.

[0035] Working principle: During use, when the staff needs to install the laser welding head 2 on the power arm body 3, the staff first places the mounting column 48 into the inside of the mounting ring 42, and then moves the laser welding head 2 left and right, so that the mounting column 48 rotates inside the mounting ring 42.

[0036] In the process of placing the mounting post 48 into the mounting ring 42, the outer wall of the mounting post 48 squeezes the spherical surface of the fixing block 44, so that the fixing block 44 enters the interior of the sliding groove 43. When the mounting post 48 rotates left and right, when it rotates until the connecting hole 49 is exactly at the same horizontal position as the fixing block 44, the fixing block 44 moves to the position entering the interior of the connecting hole 49 under the elastic force of the spring 45. Since the staff is rotating the equipment at this time and needs to squeeze the spherical surface of the fixing block 44, the staff can feel obvious resistance at this time. Therefore, when the staff rotates until the fixing block 44 enters the connecting hole 49, they can clearly notice it and ensure that they stop rotating after noticing that the fixing block 44 enters the connecting hole 49.

[0037] Then, the staff first moves the control rod 56 upward, so that the control rod 56 moves from the bottom end position of the concave groove 55 to the area where the horizontal groove is located above, and then the staff moves the control rod 56. Since the sliding direction of the control rod 56 and the swivel 52 is only vertical sliding, when the control rod 56 moves toward the horizontal direction, it can drive the swivel 52 to rotate inside the rotating groove 51, so that the area where the sliding groove 53 and the L-shaped rod 54 are at the same horizontal position is closer to the center position of the swivel 52, so that the L-shaped rod 54 is driven by the sliding groove 53 to move closer to the swivel. 52 is moved to the center position. When the L-shaped rod 54 moves to the position in contact with the fixed block 44, the staff continues to move, and the fixed block 44 can be moved under the push of the L-shaped rod 54, so that the fixed block 44 enters the position inside the connecting hole 49. In addition to the hemispherical part, a part of the cylindrical area is added. Therefore, at this time, even if the mounting column 48 is subjected to an upward or left-right moving force, the spherical surface of the fixed block 44 cannot be squeezed to shrink the fixed block 44, thereby ensuring that when the laser welding head 2 is used for welding operations, the laser welding head 2 will not be separated from the power-assisting arm body 3.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
