[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Reference Figure 1-Figure 11 A mechanical engineering telescopic arm laser welding device comprises a U-shaped support plate 2, a U-shaped groove surface array of the U-shaped support plate 2 is provided with a guide mechanism 1, a lifting mechanism 3 is provided below the U-shaped support plate 2, an electric slide rail 4 is provided on the upper surface of the U-shaped support plate 2, the electric slide rail 4 comprises an electric slider 40, a fine-tuning mechanism 5 is provided on one side of the electric slider 40, and a laser welding head 6 is provided at one end of the fine-tuning mechanism 5.

[0036] In order to realize the action of conveying and guiding the material to be welded, the guide mechanism 1 set with the U-shaped groove surface array of the U-shaped support plate 2 can provide precise guidance for the entire welding process, ensure that the material to be welded moves along a preset path, reduce the deviation of the welding trajectory, and thus improve the accuracy of the welding position, especially for some complex-shaped materials to be welded with high requirements on welding accuracy, which can ensure that the weld meets the design requirements and improve the welding quality.

[0037] In order to realize the welding action of the welding material, the fine-tuning mechanism 5 located on one side of the electric slider 40 can make slight adjustments to the position of the laser welding head 6 before welding. When faced with slight size differences between different telescopic arms or when precise positioning of the welding starting point, end point and other positions is required, the laser welding head 6 can be accurately adjusted to the optimal welding position through the fine-tuning mechanism, thereby further improving the accuracy of welding and ensuring the consistency of the welding effect.

[0038] In order to realize the smooth conveying of different welding materials, the lifting mechanism 3 has different sizes and weights of different materials to be welded. By setting the lifting mechanism 3, during the transmission of the materials to be welded, one side of the lifting mechanism 3 can be controlled to rise or fall, so that the pressure of the materials to be welded on the guide combination composed of multiple rollers 14 and universal joints 15 is kept within a safe range, avoiding damage to the guide combination due to excessive weight of the materials to be welded.

[0039] In this embodiment, if Figure 2 and Figure 5 As shown, the guide mechanism 1 includes a U-shaped groove 10 opened on the plate body of the U-shaped support plate 2, and motors I11 are fixedly connected to the two ends of the U-shaped groove 10 respectively. Gears I12 are arranged in an array on the inner wall of the U-shaped groove 10, and the output shafts of the two motors I11 are fixedly connected to one side of the gears I12 arranged at the two ends of the U-shaped groove 10 respectively. The surface of the gears I12 arranged in the array is meshed with a toothed belt 13. Rollers 14 are arranged in an array in the U-shaped groove of the U-shaped support plate 2, and universal joints 15 are arranged between the longitudinal rollers 14. The two ends of the universal joints 15 are fixedly connected to the side surfaces of two adjacent rollers 14 respectively. Bearings compatible with the array-shaped gears I12 are symmetrically embedded in the inner wall of the U-shaped groove close to the U-shaped support plate 2. One side of each gear I12 is fixedly connected to the inner ring of the corresponding bearing respectively, and the other side of each bearing inner ring is fixedly connected to one side of the nearest roller 14 through a cloud connecting column. The sides are rotatably connected with guide wheels 16, and sliding grooves 17 are provided on both sides of the U-shaped groove of the U-shaped support plate 2. A rubber ring is sleeved on the surface of each roller 14; the rollers 14 are arranged in an array in the U-shaped groove of the U-shaped support plate 2, and the longitudinal rollers 14 are fixedly connected by universal joints 15. The existence of the universal joints 15 enables the adjacent rollers 14 to adapt to different force conditions and changes in movement directions, ensuring that the rollers 14 can still work together in a complex movement process to maintain the stability of the overall movement. At the same time, during the force process of the combination of multiple rollers 14, due to the existence of the universal joints 15, the combination of multiple rollers 14 will drop a certain height, and the combined force of the multiple rollers 14 is biased towards the material to be welded, and the contact surface with the material to be welded is increased to a certain extent, and the rubber ring of the roller 14 can increase the friction force during the movement of the material to be welded, so that the movement of the entire material to be welded in the U-shaped groove is smoother and more stable;

[0040] The guide wheels 16 rotatably connected to both sides of the U-shaped groove of the U-shaped support plate 2 can play a lateral limiting and guiding role for the materials to be welded moving in the U-shaped groove.

[0041] In this embodiment, if Figure 3As shown, the lifting mechanism 3 includes hydraulic cylinders 31 symmetrically arranged in an array along the central axis of the U-shaped groove of the U-shaped support plate 2, and fixed plates 32 are symmetrically arranged on the upper ends of the hydraulic cylinders 31. The upper surface of each fixed plate 32 is arranged in an array with support rods 33, and the upper end of each support rod 33 is rotatably connected to an auxiliary wheel 34; rectangular holes are arranged in an array in the U-shaped groove of the U-shaped support plate 2, and each rectangular hole is located between two adjacent rollers 14 in the longitudinal direction, and each rectangular hole is respectively adapted to the surface of the auxiliary wheel 34.

[0042] Specifically, the symmetrically arranged fixed plate 32 can be controlled to rise and fall respectively by the hydraulic cylinder 31. If the pressure of the material to be welded on the combination of rollers 14 is too large, the auxiliary wheel 34 at the upper end of the fixed plate 32 can be driven to rise by controlling the hydraulic cylinder 31. The rising auxiliary wheel 34 contacts the bottom end of the material to be welded to provide a certain supporting force for it.

[0043] In this embodiment, if Figure 6-Figure 11 The fine-tuning mechanism 5 includes an auxiliary plate 51, one side of the auxiliary plate 51 is fixedly connected to one side of the electric slider 40, and both ends of the auxiliary plate 51 are fixedly connected to a base 52, and an electric telescopic rod 53 is embedded in the body of the base 52. One end of the electric telescopic rod 53 embedded in one base 52 is fixedly connected to the connecting plate, and one end of the electric telescopic rod 53 embedded in the other base 52 is fixedly connected to the motor box 54. Two screw rods 55 are arranged in parallel in the vertical direction on one side of the motor box 54. One end of the screw rod 55 is rotatably connected to one side of the connecting plate. The other end of 55 is fixedly connected to the output shaft of the motor in the motor box 54, the screw nuts between the two screw rods 55 are fixedly connected, a slider 56 is fixedly connected to one side of the screw nut, a limiting groove 57 is provided on the side of the slider 56, a gear groove is arranged inside the slider 56, a gear II59 is arranged inside the gear groove, a motor II58 is arranged on the outer side of the slider 56, the output shaft of the motor II58 passes through the body of the slider 56 and is fixedly connected to the side of the gear II59, and the output shaft of the motor II58 is rotationally connected to the body of the slider 56.

[0044] Specifically, the electric telescopic rod 53 is arranged in the base 52 to which the two ends of the auxiliary plate 51 are fixedly connected, and one end of the electric telescopic rod 53 is connected to the connecting plate, and the other end is connected to the motor box 54. By controlling the extension and retraction of the electric telescopic rod 53, the relative position adjustment between the motor box 54 and the connecting plate within a certain range can be achieved, thereby driving the subsequent screw rod 55 connected thereto to change its position in the lateral direction. The screw rod 55 and the motor box 54 can accurately control the displacement of the screw nut on the screw rod 55, thereby achieving precise position adjustment of the slider 56 connected thereto in the lateral direction, so that the laser welding head 6 can make subtle and precise position changes in the lateral dimension to accurately align with the specific welding point or weld position on the welding flow to be welded, thereby ensuring welding accuracy.

[0045] In this embodiment, if Figure 7-Figure 9 The inner wall of the limit groove 57 is slidably connected with a slider II510, the outer side surface of the slider II510 is set as a toothed surface, the toothed surface of the slider II510 is meshed with the toothed surface of the gear II59, the inner side surface of the slider II510 is fixedly connected with a slider III511, the upper and lower sides of the slider III511 are respectively provided with a card groove 512, the outer side surface of the slider III511 is provided with a motor III513, the inner side surface of the slider III511 is provided with a movable groove, and the inside of the movable groove is provided with a gear III514, the output shaft of the motor III513 passes through the body of the slider III511 and is fixedly connected to the side of the gear III514, and the output shaft of the motor III513 is rotatably connected to the body of the slider III511; one side of the slider III511 is provided with There is a hemisphere 515, and a limit hook 516 is symmetrically arranged on one side of the hemisphere 515 along its axis of symmetry, one end of the limit hook 516 is slidably engaged with the inner wall of the slot 512, an industrial camera 517 is embedded in one side of the hemisphere 515, and a limit plate 518 is symmetrically arranged on the side of the hemisphere 515 along the circumferential array of its axis, and an electric telescopic rod II519 is arranged between the two symmetrically arranged limit plates 518, each limit plate 518 has a plate body with a slot, and the inner wall of the slot is slidably connected with a T-screw 520, one end of the T-screw 520 is threadedly connected to the surface of the electric telescopic rod II519, one end of the electric telescopic rod II519 is electromagnetically connected to a column 521, one end of the column 521 is fixedly connected to a disc, and one side of the disc is fixedly connected to one side of the laser welding head 6.

[0046] Specifically, the crescent-shaped slider II510 and slider III511 slide alternately in the vertical and horizontal directions, realizing an all-round, multi-dimensional position adjustment function from coarse adjustment to fine adjustment, which plays a vital role in improving the welding accuracy and operational flexibility of the telescopic arm laser welding equipment in mechanical engineering; the position information of the weld is obtained by monitoring means of the industrial camera 517, and then the fine-tuning function of the slider II510, slider III511 and other components in the horizontal and vertical directions is utilized, and the laser welding head 6 can move along the weld with extremely high precision. For some telescopic arm welding with high precision requirements, such as telescopic arms in the aerospace field or high-precision machinery manufacturing, this precise tracking capability can ensure uniform weld width and good fusion, achieving extremely high welding quality standards; especially when the laser welding head 6 is close to the starting and ending points of the weld, or when welding at the corners of some special shapes of welds, the gear III514 inside the slider III511 is driven by the motor III513 and other components, so as to make slight position adjustments and angle corrections to the laser welding head 6, ensuring that the welding head is always welding in the best condition, thereby improving the accuracy and quality of the entire welding process, so that the final welding product can meet various strict engineering requirements.

[0047] In this embodiment, a rubber gasket is provided on one side of the contact surface between the T-screw 520 and the limiting plate 518; specifically, the presence of the rubber gasket can increase the friction between the T-screw 520 and the limiting plate 518, thereby preventing the electric telescopic rod II519 from loosening after being limited and fixed.

[0048] In this embodiment, an electromagnet is provided at one end of the electric telescopic rod II519; specifically, the presence of the electromagnet enables electromagnetic connection between the electric telescopic rod II519 and the column 521. Compared with the traditional mechanical connection method, this electromagnetic connection has good fit while ensuring a certain connection strength. When the equipment is subjected to vibration and impact during operation or when the position and posture of the laser welding head 6 are adjusted, the electromagnet can tightly adsorb the column 521 to ensure that the connection between the electric telescopic rod II519 and the column 521 is stable and reliable, and will not easily become loose or detached, thereby maintaining the stability of the entire structure, ensuring precise control and stable operation of the welding head, and at the same time, after power failure, it is convenient to replace the laser welding head 6.

[0049] Reference Figure 1-Figure 11 , the operating steps of a mechanical engineering telescopic arm laser welding equipment are as follows:

[0050] Step 1: Before welding, manually adjust the electric telescopic rod II519 to the appropriate position of the limit plate 518, tighten the T-screw 520, turn on the motor I11, and the motor I11 drives the gear I12 and the toothed belt 13 fixed thereto to rotate through the output shaft, thereby driving the roller 14 and the universal joint 15 guide combination to rotate, and then place the material to be welded on the guide combination, and under the joint action of the rotating roller 14 and the rubber ring sleeved on its surface, the material to be welded is driven to move to the welding position, and the operator begins to manually adjust the position of the electric slide rail 4. When the material to be welded is too heavy, the hydraulic cylinder 31 drives the fixed plate 32 and the support rod 33 at its upper end to move upward until the surface of the auxiliary wheel 34 contacts the lower surface of the material to be welded, and the auxiliary wheel 34 continues to rise until the pressure of the material to be welded on the guide combination of the roller 14 and the universal joint 15 is reduced to a preset range;

[0051] Step 2: The electric slide rail 4 drives the fine-adjusting mechanism 5 to approach the welding position of the material to be welded through the electric slider 40, and the electric telescopic rod 53 starts to work, driving the screw rod 55 and the slider 56 at its end to approach. The electric telescopic rod 53 stops after extending to a specified length. At the same time, the screw nut is fine-tuned laterally under the action of the motor box 54 and the screw rod 55, and the hemisphere 515 is moved to the welding position, and then the motor box 54 stops working;

[0052] Step three, under the action of industrial camera 517, motor II58 and motor III513 rotate at the same time, each driving the gear at the output shaft end to rotate, slider II510 and slider III511 start to rotate respectively until the laser welding head 6 is vertical to the position to be welded. If the welding range is tightly within the diameter range of the hemisphere 515, it is only necessary to adjust the electric telescopic rod II519 to dock with the column 521, and the electromagnet at its end is energized. The electric telescopic rod II519 originally connected to the column 521 by electromagnetic will shrink after the electromagnet at its end is powered off, thereby enabling the laser welding head to complete the laser welding work in a small range.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
