Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present application.

[0038] Embodiment

[0039] The present application provides a building wallboard keel welding device, mainly solves the prior art in the building wallboard keel welding, most of the longitudinal keel and vertical keel need to be attached to the wall for splicing or hanging top operation and then splicing operation, often cause the above structure and the wall 1 between the small spacing, cause the above structure in the welding gun in the relatively narrow space welding, welding gun equipment is not easy to expand;And, most of the splicing of longitudinal keel and vertical keel is away from the welder, which is not conducive to the operation of the operator, resulting in that the longitudinal keel and vertical keel can only be welded to part of the surface when splicing, and the splicing intersection of longitudinal keel and vertical keel is more, and the continuity of welding cannot be guaranteed when welding with conventional welding equipment 206 and conventional operation mode, and the splicing of the two is prone to breakage after long time use. Figures 1-12 As shown, the structure includes a fixed rack 3, the fixed rack 3 is in a frame structure, the upper end and the lower end of the fixed rack 3 are both installed with clamping mechanisms, the two sets of clamping mechanisms are mutually symmetrical, and the clamping mechanisms are used for clamping the vertical skeleton 102;To provide a stable foundation for the overall structure.

[0040] The dynamic frame 2 is installed in the fixed frame 3 and can move relative to the fixed frame 3. The mounting frame 213 on the dynamic frame 2 can be one group or two groups, which are suitable for different construction environments. The mounting frame 213 is fixedly connected with the mounting groove on the dynamic frame 2 through a screw rod. The side wall of the mounting frame 213 is provided with an annular holding frame structure 202. The side of the holding frame structure 202 away from the mounting frame 213 is provided with an inlet and outlet, so that the holding frame structure 202 is in an arc-shaped structure, which reduces the size and facilitates the expansion of the structure in a small space. Then, the longitudinal skeleton is positioned. The horizontal longitudinal skeleton 101 is inserted through the inlet and outlet on the side of the holding frame structure 202 away from the mounting frame 213, and then is clamped into the embedded groove on the vertical skeleton 102. The positioning structure around the holding frame structure 202 cooperates with the fixed frame to preliminarily position the longitudinal skeleton, so that the longitudinal skeleton 101 and the vertical skeleton 102 are perpendicular to each other, the position of the longitudinal skeleton 101 is accurate, and the vertical skeleton 102 is not shaken during welding, the longitudinal skeleton 101 is prevented from being deviated during welding, and the stability of the foundation after splicing is improved.

[0041] The side wall of the mounting frame 213 is rotatably provided with a positioning frame 201 coaxial with the holding frame structure 202 and in an arc shape. The length of the positioning frame 201 is one-fourth of a circular arc, which is used to adapt to the fact that the intersection points of the longitudinal keel and the vertical keel are generally located in narrow areas such as corners and ceilings. The positioning frame 201 can reciprocate 0-180 degrees on the outside of the holding frame structure 202. After cooperating with the L-shaped positioning frame 203, the welding gun equipment can move along the predetermined route in the narrow space, avoiding the interference of the equipment with the movement, and then the welding equipment 206 can perform continuous welding operation. Through the structure, the welding operation can be performed on the welding gap away from the welding operation.

[0042] The mounting frame 213 is provided with a second driving structure for driving the positioning frame 201 to move in a circular motion;

[0043] The holding frame structure 202 is provided with a positioning structure around the holding frame structure 202 for positioning the longitudinal skeleton 101 and the positioning frame 201;

[0044] The inner side of the position adjusting frame 201 is provided with a positioning frame 203; after the position adjusting frame 201 moves to the preset position, the positioning frame 203 is parallel to the longitudinal skeleton 101; the coaxial design of the position adjusting frame 201 and the embracing frame structure 202 enables the positioning frame 203 to be accurately aligned with the longitudinal skeleton 101 and to determine the center position of the above structure on the longitudinal skeleton 101; the position adjusting frame 201 makes arc motion around the embracing frame structure 202 to compensate for the angle deviation of the welding gun equipment during operation, realizes the self-adaptive positioning of the welding gun output end and the weld, and enables the position adjusting frame 201 to make circular motion around the longitudinal skeleton 101, so that the distance between the position adjusting frame 201 and each outer side surface of the longitudinal skeleton 101 is equal. Thus, the positioning frame 203 is always parallel to the longitudinal skeleton 101, the moving path of the welding equipment 206 is consistent with the gap track after the horizontally arranged longitudinal skeleton 101 and the vertical skeleton 102 are spliced, and the welding point on the same straight line is ensured to be consistent during welding.

[0045] The side wall of the positioning frame 203 is provided with a walking mechanism, the outer side of the walking mechanism is provided with a support frame 207, the support frame 207 is provided with the welding equipment 206, and the support frame 207 is provided with a first driving structure for driving the welding equipment 206 to reciprocate. After the positioning frame 203 is parallel to the longitudinal skeleton 101, the walking mechanism on the side wall of the positioning frame 203 is started to drive the support frame 207 and the welding equipment 206 to move along the length direction of the positioning frame 203, that is, to make periodic rotary motion around the gap track after the longitudinal skeleton 101 and the vertical skeleton 102 are spliced. At the same time, the first driving structure in the support frame 207 drives the welding equipment 206 to make reciprocating motion on the support frame 207, so as to adjust the distance between the output end of the welding equipment 206 and the gap after the longitudinal skeleton 101 and the vertical skeleton 102 are spliced, to ensure the accuracy of the welding point and the consistency of the weld track during the movement of the welding equipment 206, and then to automatically weld the intersection point (i.e. the “keel” connection point) of the vertical skeleton 102 and the longitudinal skeleton 101. The above structure makes the rotary center of the longitudinal skeleton 101 and the center of the position adjusting frame 201 coaxial through the positioning structure, so as to ensure that the positioning frame 203 is always parallel to a side surface of the longitudinal skeleton 101 when welding a certain surface of the intersection point, to ensure that the moving path of the welding equipment 206 is consistent with the gap track after the horizontally arranged longitudinal skeleton 101 and the vertical skeleton 102 are spliced in the transverse direction, and to reduce manual intervention. The welding gun on the welding path always moves along the horizontal line through the mechanical structure, improves the welding precision, and improves the structural strength of the skeleton structure of the building wall plate.

[0046] When the longitudinal skeleton is welded on the vertical skeleton through the above structure, the longitudinal skeleton can be fixed to prevent it from deflecting or shaking due to welding stress, and to reduce the cumulative error of the longitudinal skeleton after being welded in sequence.

[0047] Preferably, the mounting frame 213 is a telescopic rod structure, which can be automatically telescoped to adjust the spacing of the clamping frame structure 202 relative to the welding gap.

[0048] Preferably, the number of positioning frames 203 is 2, and the two positioning frames are located at the two ends of the inside of the adjusting frame 201, and the reverse extension lines of the two positioning frames 203 are perpendicular to each other.

[0049] Preferably, the number of positioning frames 203 is 1, and the adjusting frame 201 is provided with an arc-shaped groove on the inner arc surface thereof, both ends of the positioning frame 203 are embedded in the groove, an annular transmission belt 502 is rotationally arranged in the groove, arc-shaped limiting plates 504 are arranged on the opposite inner side walls of the groove, the arc-shaped limiting plates 504 abut against one horizontal section of the transmission belt 502, drive wheels 503 which are in driving connection with the transmission belt 502 are rotationally arranged at both ends of the groove, the drive wheels 503 are internally provided with motors which are hub motors, the drive wheels 503 and the motors are integrally designed to reduce the occupied space of the equipment, the transmission belt 502 is driven to rotate in the groove, and both ends of the positioning frame 203 are connected with the outer side wall of the transmission belt 502 through a hinge structure.

[0050] In some technical solutions of the present application, the positioning structure comprises mounting cylinders 205 mounted on the inner side walls of the clamping frame structure 202, the number of the mounting cylinders 205 is 3, and the reverse extension lines of the three mounting cylinders 205 intersect at the center of the clamping frame structure 202. Guiding rods 211 are arranged in the mounting cylinders 205, the outer diameter of the guiding rods 211 matches the inner diameter of the mounting cylinders 205, and the mounting cylinders 205 play a guiding and limiting role for the movement of the guiding rods 211. The guiding rods 211 are sleeved with return springs 210 connected with the mounting cylinders 205, the end portions of the guiding rods 211 outside the mounting cylinders 205 are provided with wheel frames 208, the wheel frames 208 are rotationally arranged with wheel bodies 209, and the wheel bodies 209 are rubber wheels. The end portions of the guiding rods 211 inside the mounting cylinders 205 are provided with first position sensors 9, and a plurality of second position sensors 10 are arranged on the outer side walls of the wheel bodies 209. The return springs 210 make the wheel bodies 209 always adhere to the surface of the skeleton, eliminating the assembly gap. After the guiding rods 211 contact with the outer wall of the longitudinal skeleton 101, they are compressed. The linear movement of the guiding rods 211 in the mounting cylinders 205 changes the position of the first position sensors 9, so that the radial position of the clamping frame structure 202 relative to the longitudinal skeleton 101 is detected by the first position sensors 9, and the center of the clamping frame structure 202 on the longitudinal skeleton 101 is determined in combination with the width or length dimension of the longitudinal skeleton. The second position sensors 10 calculate the axial position of the clamping frame structure 202 relative to the longitudinal skeleton 101 through the rotation counting of the wheel bodies 209, realize three-dimensional dynamic positioning, and thus ensure the center of the clamping frame structure 202 and the longitudinal skeleton 101, providing a reference for subsequent welding operation.

[0051] In some technical solutions of the present application, a plurality of positioning columns 204 are arranged around the outer side wall of the holder structure 202, and the number of the positioning columns 204 is three. One of the positioning columns 204 is installed between the holder structure 202 and the mounting frame 213, and is used to connect the holder structure 202 and the mounting frame 213. The positioning column 204 is provided with a connecting frame 6 connected with the mounting frame 213, and a mounting space is reserved between the positioning column 204 and the mounting frame 213 to provide a movable space for the positioning frame 201. A limiting groove is formed in the side wall of the positioning column 204 along the extension direction of the positioning column 204, and a limiting rod 11 is slidably arranged in the limiting groove. A limiting spring 12 is sleeved on the outer side wall of the limiting rod 11. A locking groove is formed in the side wall of the positioning frame 203 and is adapted to the limiting rod 11, and the locking groove is in a rectangular shape. The locking groove and the limiting rod 11 form an interference fit, which is used to fix the positioning frame 201 moved to a preset position, and limits the circular motion of the positioning frame 201. When the positioning frame 201 reaches the preset position, the limiting rod 11 is clamped into the locking groove, and the pre-tightening force of the limiting spring 12 maintains the locking state, resists the welding vibration, absorbs the equipment vibration energy, and prevents accidental unlocking.

[0052] In some technical solutions of the present application, the second driving structure includes a fourth driving motor 505 installed in the mounting frame 213. A driving gear 5 is installed on the output end of the fourth driving motor 505. A rack 501 engaged with the driving gear 5 is installed on the outer side of the positioning frame 201, and the rack 501 is in an arc shape. A guide strip 4 coaxial with the positioning frame 201 is installed on the outer side wall of the positioning frame 201. A first guide groove 212 adapted to the guide strip 4 is arranged on the side wall of the positioning column. The above structure converts the rotary force output by the fourth driving motor 505 into the precise circular motion of the positioning frame 201. The displacement accuracy of the rack 501 is controlled by the rack 501. The cooperation of the first guide groove 212 and the guide strip 4 eliminates the radial swing, and ensures that the trajectory of the positioning frame 201 is coaxial with the holder structure 202.

The walking wheels 701 form rolling friction with the positioning frame 203, which reduces the moving resistance. The walking channel wraps part of the walking wheels 701 and limits the transverse displacement. The third driving motor 709 drives the walking wheels 701 to roll on the surface of the positioning frame 203, thereby driving the walking frame 7 to move along the length direction of the positioning frame 203. The walking wheels 701 are embedded in the walking channel to prevent derailment. Thus, the walking mechanism can drive the support frame 207 and the welding equipment 206 to move along the length direction of the positioning frame 203, so as to make the welding equipment 206 move along the gap track of the longitudinal skeleton 101 and the vertical skeleton 102 after splicing.

The push rod structure provides high thrust direct drive and is suitable for heavy welding equipment 206. The sliding groove restricts the displacement seat 704 to make only single-axis linear motion, and the linear sliding does not deviate, which can adjust the distance between the welding gun and the weld seam at ease, ensure the alignment of the weld seam between the welding gun track and the skeleton, facilitate the control of the welding gun posture, and ensure the welding quality.

When the first driving motor 705 drives the rotating seat 703 to adjust the pitch angle of the welding gun through the rotating shaft, the second driving motor 706 controls the horizontal rotation angle of the welding gun through the rotating seat 703. And control the displacement seat 704 to move in the sliding groove, that is, the welding gun can be multi-degree-of-freedom synchronous attitude adjustment, which ensures the welding quality of the structure to the weld.

[0056] Preferably, a guide groove 708 is formed on the outer side of the support frame 207, and a limiting block 707 connected with the rotating seat 703 is slidably arranged in the guide groove 708, so as to guide the movement of the rotating seat 703 and make it reciprocate linearly in the sliding groove.

[0057] In some technical solutions of the present application, the mounting cylinder 205 is provided with a third driving structure 8 for driving the guide rod 211 to rotate. The third driving structure 8 (such as a micro motor) drives the guide rod 211 to rotate, the guide rod 211 is slidably connected with the output end of the third driving structure 8 through a sleeve structure 801, and the movement of the guide rod 211 along the axial direction of the mounting cylinder 205 is limited. After the guide rod 211 is driven to rotate, the wheel body 209 is driven to rotate, the wheel body 209 rotates to clean the oil stains / rust marks on the surface of the skeleton, improve the detection accuracy of the sensor, and lock the longitudinal skeleton 101.

[0058] In some technical solutions of the present application, the clamping mechanism comprises two retaining frames 302 mounted on the outer side of the fixed frame 3, first push rod structures 304 are mounted on the opposite side walls of the two retaining frames 302, and clamping plates 303 are mounted on the pushing ends of the first push rod structures 304. The first push rod structures 304 push the two clamping plates 303 to move towards each other to clamp the vertical skeleton 102 from both sides. After the clamping plates 303 contact the skeleton, the push rod continuously applies pressure to a preset clamping force, the symmetrical push rod structure applies balanced clamping force, and unilateral extrusion deformation is avoided.

[0059] Preferably, a pressure sensor is further arranged in the telescopic end of the first push rod structure 304 to dynamically adjust the clamping force.

[0060] Preferably, concave-convex marks are formed on the clamping surface of the clamping plate 303 to increase the clamping effect of the structure on the vertical skeleton 102.

[0061] In some technical solutions of the present application, the second guide groove 301 is arranged on both sides of the movable rack 2, and a guide block is slidably arranged in the second guide groove 301. The guide block is connected with the fixed rack 3 on the same side. When the movable rack 2 moves, the guide block slides in the second guide groove 301 of the fixed rack 3, so that the movable rack 2 only moves horizontally and linearly, and the guide block cooperates with the groove wall to eliminate the movement swing. When the movable rack 2 no longer moves, the guide block is locked by the electromagnetic lock installed in the second guide groove 301, so that the movable rack 2 cannot move randomly, and the problem of the center of the rack structure deviating from the preset track occurs, thereby ensuring the precision of the welding operation in the narrow space.

[0062] The above is only the preferred embodiment of the present application, and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
