DETAILED DESCRIPTION

[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Example 1. This example aims to provide a welding tool for the keel frame of a large-space assembled ceiling, which is used to assist in welding the keel frame structure in an antique caisson-style ceiling structure, and aims to solve the problems existing in the prior art such as complex welding position determination, time-consuming and labor-intensive welding process, difficult quality control, and low production efficiency.

[0023] like Figure 1-9 As shown, the large space assembled ceiling keel welding tool provided in this embodiment includes a support frame 1, a gantry assembly 2, a mounting frame 3, a suction cup assembly 4, a flip assembly 5, an angle adjustment assembly 9 and a welding machine 99, etc. Figure 1 As shown, in this embodiment, the gantry group 2 is vertically arranged on the front side of the support frame 1, and its bottom is slidably installed on the bottom plate 7 of the support frame 11, and together with the support frame 1, it forms an avoidance space for keel frame welding; the mounting frame 3 is fixedly installed inside the support frame 1, and the keel component 66 is mounted in the mounting frame 3, and under the action of the flip assembly 5, the keel component 6 can be flipped 180 degrees in the avoidance space.

[0024] Specifically, Figure 2-4As shown, in this embodiment, the mounting frame 3 includes a main frame, a bracket and a locking assembly. The main frame is vertically fixedly installed in the middle of the support frame 1, that is, the upper and lower ends of the main frame are welded and fixed to the inner wall of the support frame 1, and each bracket is symmetrically welded on both sides of the main frame. In this embodiment, the installation position of each bracket and the main frame is adaptively preset according to the number and interval of the transverse keels 61 in the keel component 6. Figure 2 As shown, vertical main grooves 31 and horizontal branch grooves 34 are correspondingly opened in the main frame and the bracket, and the opening direction is toward the welding machine 99 on the gantry group 2, and each branch groove 34 is connected to the main groove 31 respectively, so as to form a plurality of cross-shaped passages, and locking components are respectively provided in each branch groove 34 on both sides of the main groove 31.

[0025] like Figure 2 As shown, in this embodiment, the locking assembly includes a top block 32 and a top spring 33. The top block 32 is slidably installed in the branch groove 34. One end of the top spring 33 is fixedly connected to the top block 32, and the other end is fixed to an end of the branch groove 34 away from the main groove 31. When each individual transverse keel 61 and vertical keel 62 are respectively placed in the main groove 31 and the branch groove 34, the top block 32 can be used to press each transverse keel 61 tightly against the vertical keel 62, so that the welding machine 99 can weld the side position thereof. It should be noted that the elastic coefficients of the top springs 33 in each group of branch grooves 34 from top to bottom are different, and they are respectively adapted to the length of the transverse keels 61 at the corresponding positions, so that when the transverse keels 61 of different lengths and different positions are placed in the branch groove 34, the elastic pressing force of the top springs 33 with different elastic coefficients can be used to make each transverse keel 61 tightly contact with the vertical keel 62 in the main groove 31.

[0026] Furthermore, after the transverse keel 61 is placed in the branch groove 34, in order to ensure that each transverse keel 61 is in the same plane and to avoid that part of the transverse keel 61 protrudes outward or part of the transverse keel 61 is placed too deep, in actual application, the depth of each bracket of the mounting frame 3 can be prefabricated to be slightly smaller than the width of the transverse keel 61, or as described in the present embodiment, a limiting groove 35 is opened on the side wall of the top block 32 close to the main groove 31, and the inner diameter of the limiting groove 35 is adapted to the inner diameter of the transverse keel 61. When the technician places the transverse keel 61 in the branch groove 34, the position of each group of transverse keels 61 can be limited by inserting the transverse keel 61 and the limiting groove 35, thereby further improving the welding accuracy and avoiding unevenness that affects the welding quality.

[0027] like Figure 3As shown, a suction cup 41 is also provided in the branch groove 34. In the specific structure, in this embodiment, a suction cup assembly 4 is provided on the rear side of the support frame 1. The suction cup assembly 4 includes a suction cup frame 43, an electric push rod 44, an air pump 42 and a suction cup 41. The suction cup frame 43 is fixedly installed on the rear side of the support frame 1 and is parallel to the mounting frame 3. The air pump 42 is fixed on the top of the suction cup frame 43 to control the adsorption force of the suction cup 41. The distal end of the electric push rod 44 is fixed on the suction cup frame 43, and the output end extends inward into the branch groove 34 and is fixedly connected to the suction cup 41. In actual application, a suction cup 41 can be provided in each branch groove 34, or the suction cup 41 structure can be installed only in the middle branch groove 34. This saves costs on the one hand, and on the other hand, when the welding and fixation of each horizontal keel 61 and the vertical keel 62 in the right branch groove 34 (i.e., as shown in FIG. 2 ) are completed. Fig. 9 After the a-side welding position is reached, the electric push rod 44 is simultaneously used to make the suction cup 41 and the horizontal keel 61 adsorbed together and extend forward to the outside of the support groove 34, so that the flip assembly 5 can be turned over.

[0028] like Figure 3 and Figure 4 As shown, the flip assembly 5 is arranged above the mounting frame 3. In this embodiment, the flip assembly 5 includes a flip motor seat 51, a flip motor 52, a fixing plate 53 and a telescopic rod 54, wherein the flip motor seat 51 is fixed on the front side wall of the supporting frame 1 above the main frame, and the flip motor 52 is fixed on the flip motor seat 51, and its output shaft vertically passes through the flip motor seat 51 downward and is fixedly connected to the fixing plate 53, and the lower end of the fixing plate 53 is fixedly connected to the telescopic rod 54, and the lower end of the telescopic rod 54 is fixedly connected to a flip block adapted to the inner diameter of the vertical keel 62. Under the action of the suction cup assembly 4, the vertical keel 62 is extended forward out of the front side of the main frame. When it reaches the bottom of the flip block, the flip block is controlled by the telescopic rod 54 to match and be inserted into the vertical keel 62 downward, so that the telescopic rod 54 and the vertical keel 62 are fixed together by mechanical connection, and then by driving the flip motor 52 to rotate, the keel frame can be driven to rotate 180 degrees with the telescopic rod 54 as the rotation axis.

[0029] In addition, you can Figure 4 As shown, a flip suction cup 55 is fixedly connected to the bottom of the telescopic rod 54. Under the action of the suction cup assembly 4, the vertical keel 62 is extended forward from the front side of the main frame. When it reaches the bottom of the flip suction cup 55, the suction force of the flip suction cup 55 is controlled to rotate the keel frame 180 degrees with the telescopic rod 54 as the rotation axis. The main purpose of setting the flip assembly 5 in this embodiment is to conveniently flip the keel frame. Since the docking point of the horizontal keel 61 and the vertical keel 62 needs to be fully welded, by controlling the rotation of the keel frame, it can be ensured that the welding machine 99 can easily perform comprehensive welding on all sides of the keel frame, thereby greatly improving the welding quality and efficiency.

[0030] like Figure 1 and Figure 5 As shown, the welding machine 99 is fixedly mounted on the gantry assembly 2 through the angle adjustment assembly 9, and the gantry assembly 2 can reciprocate on the support frame 1 along the X-axis direction. In this embodiment, the gantry assembly 2 includes a transverse movement assembly, a longitudinal movement assembly and a lifting assembly 8, wherein the longitudinal movement assembly includes a connecting frame 20, a bottom support seat 26, a longitudinal movement motor 25, etc., wherein the connecting frame 20 and the bottom support seat 26 are arranged in parallel at the front side of the support frame 1, one end of the bottom support seat 26 is slidably mounted on the fixed guide rail 28 on the bottom plate 7 of the support frame 1, and the other end is slidably mounted on the guide rod 292 in the guide groove 27 below the support frame 1. In addition, a mounting groove 261 is opened in the longitudinal direction on the bottom support seat 26, and a longitudinal movement guide rail 262 is fixedly installed in the mounting groove 261. Correspondingly, a mounting groove 261 is also opened in the connecting frame 20, and a screw rod is provided in the mounting groove 261 on the connecting frame 20 along its extension direction, and the screw rod extends out of the connecting frame 20 at one end away from the support frame 1 and is transmission-connected to the longitudinal movement motor 25.

[0031] like Figure 5 As shown, a transverse movement assembly is provided at one end of the connecting frame 20 close to the supporting frame 1. In this embodiment, the transverse movement assembly includes a transverse movement motor 21, a transverse movement gear 22, a transverse movement rack 23 and a transverse movement rail 24, wherein the transverse movement rail 24 is fixed to the top of the supporting frame 1 along the x-axis direction, and the bottom of the connecting frame 20 is slidably installed on the supporting rail. The transverse movement motor 21 is fixed to the top of the connecting frame 20, and its output end extends downward and is fixedly connected to the transverse movement gear 22. The transverse movement rack 23 is fixed to the rear side wall of the supporting frame 1 and meshes with the transverse movement gear 22. Therefore, when the transverse movement motor 21 is driven to work, the meshing transmission of the transverse movement gear 22 and the transverse movement rack 23 can drive the connecting frame 20, the lifting assembly 8 and the bottom support frame to slide back and forth along the x-axis direction.

[0032] like Figure 6 and Figure 7 As shown, the lifting assembly 8 is arranged between the connecting frame 20 and the bottom support seat 26. In this embodiment, the lifting assembly 8 includes a vertical rod 29, a vertical rack 291, a guide rod 292, a slider 81, a lifting motor 82 and a lifting gear 83, wherein the upper and lower ends of the vertical rod 29 are respectively installed with the screw rod in the connecting frame 20 and the longitudinal guide rail 262 in the bottom support seat 26, so that when the longitudinal motor 2525 is driven to rotate, the lifting assembly 8 can be synchronously driven to reciprocate along the extension direction of the longitudinal guide rail 262, that is, by controlling the forward and reverse rotation of the longitudinal motor 25, it can be moved closer to or away from the support frame 1.

[0033] Furthermore, the guide rod 292 is arranged in parallel on one side of the vertical rod 29, the slider 81 is slidably mounted on the guide rod 292, the lifting motor 82 is fixed on the slider 81, and its output end extends forward, and the end is fixedly connected to the lifting gear 83. The lifting rack is fixedly installed on the vertical rod 29 along the z-axis direction and meshes with the lifting gear 83 for transmission. A welding machine 99 is also fixed on the side of the slider 81 close to the support frame 1 through the angle adjustment component 9.

[0034] The gantry assembly 2 of the present embodiment is configured such that the welding machine 99 can move back and forth along the x-axis direction by driving the transverse movement motor 21, and can drive the welding machine 99 toward or away from the support frame 1 by driving the longitudinal movement motor 25. By controlling the movement of the lifting motor 82, the welding machine 99 can be conveniently operated to weld the transverse keels 61 at different heights, thereby achieving greater flexibility.

[0035] like Figure 7 and Figure 8 As shown, the angle adjustment assembly 9 in this embodiment includes a mounting plate 90, a drive motor 91, a swing motor 92, a bearing seat 94, a ring frame 95, a swing frame 97, a fixed seat 98 and a worm gear 93 structure, wherein the mounting plate 90 is fixed to the side of the slider 81 away from the lifting rack by bolts, and bearing seats 94 are fixed at intervals on the mounting plate 90. The worm 93 is rotatably installed between adjacent bearing seats 94, and its two ends extend outward respectively, one end is transmission-connected to the drive motor 91, and the other end is connected to the swing motor 92 through a shaft sleeve, so that the worm can be synchronously driven to rotate by controlling the operation of the drive motor, and the ring frame 95 is installed above the worm 93, and one side of its bottom is fixedly sleeved on the transmission shaft of the swing motor 92, and the other side is sleeved with the drive motor 91 shaft through a bearing.

[0036] The worm gear is arranged in the ring frame 95 and meshes with the worm 93. A rotating shaft is fixedly mounted in the worm gear 96. Both ends of the rotating shaft pass through the ring frame 95 respectively and are fixedly connected to the swing frame 97. The fixed seat 98 is fixedly installed on the top of the swing frame 97. The welding machine 99 is fixedly set in the U-shaped fixed seat 98, and the output end welding rod of the welding machine 99 is facing the direction of the support frame 1.

[0037] In this embodiment, the angle adjustment component 9 is set up in such a way that when the control driving motor 91 is working, the worm 93 is driven to rotate at the same time through the transmission connection with the worm 93, and the worm wheel 96 is driven to rotate with its rotating shaft as the rotating shaft through the meshing of the worm wheel and the worm 93, so that the welding machine is driven to swing up and down with the rotating shaft as the center through the swing frame 97; when the control swing motor 92 is working, the worm 93 does not move, and the worm wheel, the swing frame 97 and the welding machine 99 are driven by the ring frame 95 with the worm 93 as the rotating shaft. In this embodiment, through the coordinated work of the driving motor 91 and the swing motor 92, the welding machine 99 can be accurately controlled, and the multi-angle welding operation is realized, so that it can swing according to the predetermined angle and position, thereby ensuring that the welding rod can accurately reach the position to be welded, which helps to reduce the error in the welding process and improve the accuracy and consistency of welding; in addition, the transmission mode of the worm wheel 93 structure has self-locking property, which can prevent the welding machine 99 from swinging unexpectedly due to external force interference during the welding process to a certain extent, which helps to ensure the stability of the welding process and improve the welding quality.

[0038] Working principle description: The high-space assembled ceiling keel welding tool provided in this embodiment is actually used, such as Fig. 9 As shown, the vertical keel 62 is placed in the main groove 31, and each transverse keel 61 is placed in the branch groove 34 on the right side of the flip assembly 5 respectively. The top block 32 is used to press each component tightly against the vertical keel 62, so as to weld the side a of the joint between each transverse keel 61 and the vertical keel 62, including the following steps: driving the transverse motor 21 to move the welding machine 99 to the right to correspond to the top transverse keel 61, and then driving the longitudinal motor 25 to move the welding machine 99 toward the keel frame. After it reaches the position of the top transverse keel 61, the welding machine 99 contacts the side seam a and starts the welding machine 99. By driving the lifting motor 82, it controls the welding machine 99 to perform welding operations on the side seam a from top to bottom.

[0039] After completion, the longitudinal motor 25 is driven to drive the welding machine 99 to move away from the keel frame, and then the suction cup 41 in the support groove 34 and the electric push rod 44 push the keel frame structure on one side to move outward, and the flip assembly 5 is controlled to be fixedly connected to the keel frame, the electric push rod 44 is retracted, and the keel frame is driven by the flip motor 52 to rotate 90 degrees to be perpendicular to the support frame 1; then the transverse motor 21 is driven to move the welding machine 99 to one side of the keel frame, and the welding rod of the welding machine 99 is downwardly adjusted by adjusting the angle adjustment assembly 9. Tilt it to match the top gap of each transverse keel 61, and start welding the b side seam. Through the cooperation of the transverse motor 21 and the lifting motor 82, the welding machine 99 first welds the b side seam from top to bottom in a "bow" shape, and then reset and adjust the angle adjustment component 9, so that the welding rod of the welding machine 99 tilts upward to match the bottom gap of each transverse keel 61, and start welding the c side seam. Through the cooperation of the transverse motor 21 and the lifting motor 82, the welding machine 99 welds the c side seam from top to bottom in a "bow" shape.

[0040] After completion, the turning motor 52 is driven to drive the keel frame to continue to rotate 90 degrees to the branch groove 34 on the left side of the turning assembly 5, and the top block 32 is used to tightly press each component against the vertical keel 62, so as to weld the side d of the butt joint between each horizontal keel 61 and the vertical keel 62. First, adjust the welding rod of the welding machine 99 to be perpendicular to it, and then repeat the side seam welding operation according to the above a. It should be noted that when placing the horizontal keel 61, the top block 32 and the top spring 33 can be manually pulled to achieve elastic pushing and unlocking of the keel frame; when the keel frame is turned 180 degrees and reset to the branch groove 34 on the left side again, the suction cup 41 and the electric push rod 44 in the left branch groove 34 adsorb the keel frame. In order to prevent the electric push rod 44 from pushing outwards and causing the keel frame to rotate and tilt outwards, in this process, manual assistance can be provided to provide a thrust parallel to the keel frame so that it enters the branch groove 34 on the other side.

[0041] The large-space assembled ceiling keel welding tool provided in this embodiment realizes the three-dimensional spatial movement of the welding machine through driving, automatically completes the welding operation, reduces manual intervention, improves welding efficiency and accuracy, and eliminates the need for frequent manual adjustment of the keel position. Through precise positioning and clamping devices, the stability and accuracy of the keel during the welding process are ensured, reducing manual operations and the labor intensity of technicians.

[0042] The embodiments of the present invention described above do not constitute a limitation on the protection scope of the present invention. The basic concept of the present invention is to realize the three-dimensional spatial movement of the welding machine through driving, automatically complete the welding operation, reduce manual intervention, and do not need to manually adjust the keel frame position frequently. It is only necessary to place the transverse keels of different sizes in the tooling to achieve full welding operation, which reduces manual operation, reduces the labor intensity of technicians, and effectively improves welding efficiency and accuracy. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
