Description

Technical Field

[0001] The invention belongs to the field of welding equipment, and in particular relates to a high-efficiency laser welding equipment for a roller. Background Art

[0002] Welding is a commonly used structural connection technology in manufacturing and equipment maintenance. It is a method of connecting different metals or thermoplastic materials by heating at high temperatures. Different from riveting and other methods, welding can provide better stability and sealing for equipment that does not require disassembly and maintenance.

[0003] Specifically, when welding the inner wall of a barreled structure such as a drum, due to limited space, it is often impossible to provide accurate welding positioning auxiliary equipment inside. Therefore, when welding the inner wall of the drum, changes in the surface flatness of the inner wall of the drum due to manufacturing errors or long-term use may make the welding spacing control unstable, resulting in a reduction in the welding effect.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0035] like Figure 1 、 Figure 2 、 Figures 4 to 7 1 is a diagram showing a high-efficiency laser welding device for a roller provided by an embodiment of the present invention, wherein the welding device comprises a measuring assembly provided on a measuring driven ring 4 and a welding assembly provided on a welding driven ring 5;

[0036] The measuring driven ring 4 is symmetrically provided with measuring mounting platforms 410 at both ends in the diameter direction. The measuring assembly includes a measuring mechanism 7. The measuring mechanism 7 slides radially along the measuring driven ring 4 within the measuring mounting platform 410 via a measuring magnet 710 provided at one end. The other end of the measuring mechanism 7 slides against the inner wall of the drum via a fixed measuring probe 720.

[0037] The welding driven ring 5 is provided with a measuring assembly platform 410 and a welding assembly platform 510 at both ends along the diameter direction, respectively. The measuring assembly platform 410 is provided with a measuring mechanism 7. The welding assembly includes a welding mechanism 8 that is magnetically matched with the welding assembly platform 510. When the magnetic matching strength between the welding mechanism 8 and the welding assembly platform 510 changes, the distance between the welding head 820 provided at the end of the welding mechanism 8 and the inner wall of the drum changes.

[0038] The welding equipment also includes a support frame 1 and a welding memory component arranged in a columnar structure, and the support frame 1 is respectively fitted with the measured driven ring 4 and the welding driven ring 5, and the support frame 1 is provided with a rotationally matched control ring 3, and the control ring is symmetrically provided with an electromagnetic induction coil group 310 at both ends in the diameter direction. When the curvature of the inner wall surface of the drum contacted by the measuring probe 720 changes, the distance between the measuring magnet 710 and the electromagnetic induction coil group 310 changes, the reading of the electromagnetic induction coil group 310 changes and a pair of associated measurement data is generated in the welding memory component, and the pair of measurement data is respectively used for the welding matching of the measuring mechanism 7 on the welding driven ring 5 and the magnetic matching strength control of the welding mechanism 8.

[0039] In an embodiment of the present invention, by adopting a method of sensing the change in magnetic field strength driven by a measuring probe, the surface flatness of the annular area to be welded is detected before roller welding, and then the flatness data at each welding point on the circumference is obtained and a pair of flatness data over the diameter are associated. Therefore, when welding is performed, the flatness parameters at a certain point can be measured by the measuring probe 720 and the flatness data of the object point over the diameter can be obtained by matching, and the welding mechanism 8 can be controlled to float at intervals based on the flatness data to achieve the purpose of accurate and high-quality welding. Compared with the direct welding method of the prior art, it can effectively avoid the non-constant contact spacing of the welding head caused by the change in the flatness of the welding surface, and avoid the problems of reduced welding quality and uneven distribution of welds caused by this.

[0040] In one embodiment of the present invention, the specific implementation process is that after the position of the inner wall of the drum that needs to be welded is determined, the welding equipment is sent to the corresponding position through an additional probe device such as a robotic arm. First, the flatness of the welding surface needs to be detected before welding, so the measuring driven ring is reset to the control ring 3. Because the special-shaped structure of the electromagnetic induction coil group 310 at both ends of the control ring 3 is set, it can be engaged with the measuring driven ring 4, and then when the control ring 3 rotates, the measuring driven ring 4 is driven to rotate. During this rotation, the measuring probe 720 slides with the inner wall of the drum. When the surface flatness of the inner wall of the drum changes, the radial distance changes, thereby compressing the distance between the measuring magnet 710 and the electromagnetic induction coil group 310, so that the magnetic field strength reading received by the electromagnetic induction coil group 310 changes. Therefore, during the rotation process, every time the position changes, the reading change caused by a pair of measuring probes 720 will produce a pair of readings, which can be recorded as A-A', representing the process. Measure the surface flatness readings of the inner wall of the drum at both ends of the center of the driven ring 4 (here the driven ring 4 is measured instead of the center of the drum. Therefore, an advantage of this embodiment is that during the welding process, there is no need to locate the center of the welding equipment, because a pair of reading records passing through the center can eliminate errors. Even if the welding rotation center of the welding equipment deviates from the center of the drum, it will not cause positioning deviation of the welding head during welding). When welding is performed after the measurement is completed, the welding driven ring 5 is controlled to reset to the control ring 3 to engage, and the control ring 3 is used to control the rotation of the welding driven ring 5. During this process, the measuring mechanism 7 on the welding transmission ring 5 will obtain a reading A, which can then be matched to the corresponding reading A', so that the welding mechanism 8 is floatingly controlled through the welding assembly table 510 according to A' to control the distance between the welding head and the inner wall of the drum (when the ring to be welded is greater than 180 degrees, combined welding can be performed by segmented measurement welding).

[0041] like Figure 5 As shown, as a preferred embodiment of the present invention, the measuring mechanism 7 is further provided with a reset stretching member 730 at the end position of the measuring probe 720, and the reset stretching member 730 is a magnetic mechanism, and the reset stretching member 730 is an arc structure on the side facing the inner wall of the drum. When there is a notch structure along the circumferential direction of the inner wall of the drum, the vertical overlapping area between the reset stretching member 730 and the inner wall of the drum is reduced.

[0042] In one embodiment of the present invention, the structure of the measuring mechanism 7 is supplemented and defined. A common scenario is also included in the welding usage scenario. When there is a notch on the inner wall of the drum in the welding ring area, the probe may fall into the notch under normal circumstances. As the rotation continues, the probe is damaged. The welding head 820 also has this problem. Therefore, in order to avoid this problem, a reset stretching member 730 is added in this embodiment. When the reset stretching member 730 moves to the position of the notch structure, as it continues to move, a part of the reset stretching member 730 enters the area above the notch, so the vertical overlapping area with the inner wall of the drum is reduced. At this time, the magnetic force between the reset stretching member 730 and the inner wall of the drum decreases, and the pulling effect of the inner wall of the drum on the measuring mechanism 7 is reduced. The measuring mechanism 7 retracts in the opposite direction of the radius of the measuring driven ring 4 or the welding driven ring 5. In order to achieve this effect, an additional magnetic matching member needs to be provided in the measuring assembly table 410 to form a sandwich structure of the electromagnetic induction coil group 310-measuring magnet-magnetic matching member.

[0043] like Figure 5 and Figure 7 As shown in FIG. 1 , as another preferred embodiment of the present invention, the connection portion between the measuring probe 720 and the measuring magnet 710 is provided by a pair of telescopic structures that are detachable along the length direction and fixed by a tightenable locking bolt;

[0044] The welding mechanism 8 also includes a welding frame 810 for installing a welding head 820. The welding frame 810 is composed of a group of telescopic structures that are detachable along the length direction and fixed by a tightenable locking bolt. The welding frame 810 is also provided with a floating magnet 811 on one side of the welding driven ring 5. The floating magnet 811 and the welding assembly table 510 are set to slide radially along the welding driven ring 5. The welding assembly table 510 is a controllable electromagnetic component and is electrically connected to the welding memory component.

[0045] In one embodiment of the present invention, the structures of the measuring mechanism 7 and the welding mechanism 8 are supplemented, and both of them are structures with variable radial extension length that can be telescopic, so as to adapt to different roller inner diameters in different welding scenarios, thereby improving the versatility of the platform; wherein the magnetic matching method of the welding mechanism 8 and the welding assembly table 510 is limited, which is similar to the measuring magnet, both of which are sandwich magnetic structures, and can achieve a more stable control effect.

[0046] like Figures 1 to 4 and Figure 6 As shown, as a preferred embodiment of the present invention, the measuring driven ring 4 and the welding driven ring 5 are both provided with sliding control rings 6 on opposite sides, and the inner wall of the sliding control ring 6 is provided with a sliding magnetic member;

[0047] The support frame 1 is further provided with drive rails 110 arranged along the axial direction on both sides in the horizontal direction. The drive rails 110 are controllable electromagnetic components. The drive rails 110 are magnetically matched with the sliding magnetic components of the sliding control ring 6.

[0048] In one embodiment of the present invention, a control implementation method for the reset movement of the measuring driven ring 4 and the welding driven ring 6 in the length direction of the support frame 1 is supplemented, and a magnetic track drive method is adopted. By setting a horizontal drive track 110 on the support frame 1, electromagnetic coordination with the sliding control ring 6 is performed, so that the measuring driven ring 4 and the welding driven ring 6 are controlled to slide along the axial direction of the support frame 1 as needed, thereby achieving a reset effect relative to the control ring 3.

[0049] like Figure 2 、 Figure 3 、 Figure 8 and Figure 9 As shown, as another preferred embodiment of the present invention, the control ring 3 is rotatably arranged on the support frame 1, the control ring 3 is provided with an internal driven gear 320, and the welding equipment further includes a circumferential driving mechanism 9 arranged inside the support frame 1;

[0050] The circumferential drive mechanism 9 includes a drive motor 910 and a speed-changing gear set 920 provided at the end of the drive motor 910 ; the speed-changing gear set 920 includes an output gear 921 , and the output gear 921 is meshed with the internal driven gear 320 .

[0051] Furthermore, the support frame 1 further includes an assembly mechanism 2 provided at both ends thereof, the assembly mechanism 2 including:

[0052] The probe assembly seat 220 is arranged along the axis direction of the support frame 1 and is used to assemble the welding robot arm;

[0053] The crawling assembly seat 210 is arranged along the radial direction of the cross section of the support frame 1 and is used to assemble the pipeline crawling mechanical claw.

[0054] In one embodiment of the present invention, the rotation mode of the control ring 3 is supplemented. First, the control ring 3 is embedded in the support frame 1 and is rotatably arranged, so that it can achieve free rotation relative to the support frame 1. A driving motor 910 is provided inside the support frame 1, and the output end is connected to the speed gear set 920. The speed gear set 920 meshes with the internal driven gear 320 of the control ring 3 through the output gear 921 at the power end and transmits power; further, the welding equipment is also provided with a probe assembly seat 220 and a crawling assembly seat 210 at both ends of the support frame 1. When the depth of the drum is small, the equipment can be assembled on the robot arm through the probe assembly seat 220 for probe welding. When the depth of the drum is deep and the general robot arm cannot enter, a plurality of mechanical legs, mechanical claws and other structures with drive wheels can be installed on the crawling assembly seat 210, and the equipment can autonomously crawl into the drum for support and welding.

[0055] As another preferred embodiment of the present invention, the welding memory assembly includes a detection memory module and a welding reading module;

[0056] The detection memory module is used to sequentially store the magnetic field strength readings of the pair of electromagnetic induction coils 310 of the pair of measuring mechanisms 7 on the driven ring 4;

[0057] The welding reading module is used to retrieve and match the associated magnetic field strength readings of the detection memory module based on the magnetic field strength readings of the electromagnetic induction coil group 310 by the measuring mechanism 7 on the welding driven ring 5 .

[0058] In one embodiment of the present invention, the welding memory component is subdivided and split. During the measurement process, the data generated is stored by the detection memory module. During the welding process, the welding reading module matches and reads the data in the detection memory module. It should be added that for the stored data pair, when welding, the measured A may not only correspond to A' in A-A', but also may be AA. 1 A in 1 Because there may be multiple points on the circumference with consistent flatness, the welding reading module also includes a chain flatness data verification process during the data matching and reading process. For example, there is a continuous flatness data chain on a section of circular arc on the cylinder wall, such as ABADK. Then there may be two welding points corresponding to A. At this time, we can detect multiple consecutive points to obtain a continuous flatness reading, such as ABA or ADK. At this time, by matching ABA, ADK with the complete flatness data chain ABAADK, we can know the specific welding point (position 1 or position 3) corresponding to A at this welding point. Through this verification method, we can determine the data chain starting point corresponding to the current welding starting point, locate the position of the current welding point, and ensure the accurate call of the data pair during subsequent welding.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
