Description

Technical Field

[0001] This invention relates to the field of cable tray welding positioning equipment, and in particular to a cable tray welding positioning device for welding equipment. Background Technology

[0002] Cable trays are cable fixing devices used in workshops, power distribution rooms, underground pipe corridors, etc. They suspend cables away from walls and floors, leaving space for maintenance, heat dissipation, and easy cable replacement. A common type is the ladder-type cable tray, which mainly consists of two C-shaped cold-formed steel plates on the side. The plates have connecting holes for bolting between sections and supports, as well as crossbars, which are usually made of square steel. They are evenly spaced between the two C-shaped cold-formed steel plates, and both ends are welded to the side walls of the C-shaped cold-formed steel plates.

[0003] During the production of ladder-type cable trays, welding equipment and manual labor are used to weld multiple crossbars at equal intervals with both ends perpendicular to the inner side of the side steel plates. During this process, each crossbar needs to be vertically fixed to prevent displacement during welding, so that the two side steel plates can remain parallel through multiple crossbars, thus meeting the standard requirements for ladder-type cable trays. A search revealed a prior art cable tray welding device, publication number CN122077264A. This invention mainly includes a base with a through-groove at the top. A positioning component for positioning the crossbars in the cable tray is located within the groove. A fixing component one for clamping and fixing the longitudinal beam is mounted on the base, and a fixing component two for clamping and fixing the crossbars is mounted on the fixing component one. A welding component for welding the longitudinal beam and crossbars is also mounted on the base. The positioning component achieves precise equidistant positioning of the cable tray crossbars. Rotation of the screw drives the movement of opening and closing blocks one and two. Combined with the linkage extension and retraction of adjusting rods one and two, the spacing of multiple sets of positioning posts one and two can be adjusted synchronously, eliminating the need for manual positioning. However, the prior art still has the following problems:

[0004] The side plates of ladder-type cable trays are generally made of C-shaped cold-formed steel plates with inwardly extending folds on the inside to enhance the structural strength of the side plates themselves and support the cables laid inside. Existing cable tray welding devices still use positioning components based on the idea of ​​vertically placing the crossbars for positioning, without considering the space obstruction of the side plate folds.

[0005] In addition, most existing crossbar positioning mechanisms only clamp the crossbar sidewalls from the left and right sides, providing only horizontal lateral positioning constraints and lacking vertical clamping and fixing. During the welding process, the crossbar will undergo thermal deformation and warping due to the welding heat input. In addition, the mechanical vibration of the welding equipment makes the crossbar prone to vertical jumping. Summary of the Invention

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. This invention adopts a method of pre-placing the crossbars and synchronously closing and positioning the side plates on both sides, which avoids the spatial obstruction of the inner folding wings of the side plates. During the process of the side plates closing towards the center, the crossbars are pre-positioned simultaneously. Then, the crossbars are automatically slid and centered by the contact of the inner side wall of the side plate, so that both ends of each crossbar are tightly fitted with the inner wall of the side plate. This effectively eliminates the defects such as positional offset and insufficient verticality caused by the traditional oblique installation process, improves the positioning accuracy of the crossbars, and ensures the overall dimensional accuracy and structural strength of the ladder cable tray after welding.

[0021] 2. This invention uses multiple sets of horizontal bar positioning components to operate, and with the help of an inclined plane transmission structure, it achieves top surface pressing and fixing while clamping the horizontal bar laterally. It completes the limiting of the horizontal bar from both horizontal and vertical dimensions, effectively suppressing the phenomenon of horizontal bar warping due to heat and moving due to equipment vibration during the welding process, reducing the probability of incomplete welding and false welding, and improving the stability of product welding quality.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1, referring to Figures 1-9 This is the first embodiment of the present invention, which provides a welding positioning device for a cable tray of a welding equipment, including a welding frame 2 and a lead screw linear module 3 installed on both sides of the welding frame 2. A suspension 4 is installed on the lead screw linear module 3, and a welding assembly 5 is installed on the suspension 4. Figure 3 and Figure 4 As shown, the welding assembly 5 includes a vertical plate 51, a second lead screw linear module 52, and a welding head mounting seat 53. The vertical plate 51 is fixedly installed on the side wall of the suspension 4, the second lead screw linear module 52 is installed on the side wall of the suspension 4, and the welding head mounting seat 53 is installed on the nut seat of the second lead screw linear module 52. A welding head 54 is installed on the welding head mounting seat 53. The suspension 4 is moved on the welding frame 2 by the first lead screw linear module 3, so that the welding assembly 5 can move according to the position of each welding point. Then, the welding head 54 is driven up and down by the second lead screw linear module 52, so that the welding head 54 can move closer to or away from the welding point, thereby completing the welding process of the assembled ladder cable tray 1. The specific structure of the first lead screw linear module 3 and the second lead screw linear module 52 is the prior art, which is clearly known to those skilled in the art, and will not be described in detail here.

[0039] like Figure 1 As shown, the main components of the ladder-type cable tray 1 are two side plates 11 and multiple crossbars 13. The existing welding process is as follows: first, the two side plates 11 are fixed in parallel, and then each crossbar 13 is welded to the inner wall of the side plate 11 to form a ladder shape. Multiple cables are installed on the crossbars 13. In this process, if it is necessary to weld the crossbars 13, the crossbars 13 placed vertically will not be able to be placed perpendicular to the two side plates 11 due to the obstruction of the flaps 12 on the inner side of the side plate 11. They need to be placed diagonally between the two side plates 11 and then set perpendicular to the two side plates 11 before they can be welded by the welding assembly 5. Due to the change in the angle of placement, there is a problem of the crossbars 13 shifting during welding, resulting in poor positioning of the crossbars 13 and inconvenience during the welding process.

[0040] Therefore, a crossbar placement platform 7 is installed on the welding frame 2 inside the suspension 4. The crossbar placement platform 7 is used to install the crossbar 13 of the ladder cable tray 1. Specifically, as follows: Figure 8As shown, the top surface of the crossbar placement platform 7 is provided with notches 71 at equal intervals. Multiple sliding rollers 72 are rotatably connected in the notches 71. Limiting plates 73 are fixed on the top surface of the crossbar placement platform 7 located on both sides of the notches 71. Sliding grooves 74 for the crossbar positioning assembly 8 to slide are provided on the top surface of the crossbar placement platform 7 located on both sides of the limiting plates 73.

[0041] During installation, multiple crossbars 13 are placed on the top surface of the crossbar placement platform 7. The initial lateral pre-positioning is completed by the limiting plates 73 on both sides. The sliding rollers 72 in the notch 71 roll in contact with the bottom surface of the crossbar 13, which facilitates the subsequent centering adjustment of the crossbar 13. The sliding friction of the crossbar 13 during sliding is converted into rolling friction. The first groove 74 provides sliding guidance for the crossbar positioning component 8. The limiting plate 73 quickly and roughly positions the crossbar 13 when it is loaded, avoiding large deviation of the crossbar 13 during loading.

[0042] The crossbar placement platform 7 is slidably installed with multiple crossbar positioning components 8. The crossbar positioning components 8 are driven by the synchronous positioning mechanism 9 and are used to position the crossbar 13. Multiple sets of crossbar positioning components 8 are arranged one-to-one on the side of each crossbar 13. The synchronous positioning mechanism 9 outputs synchronous driving force, which drives all the crossbar positioning components 8 to move synchronously towards each other along the slide groove 74, clamping the crossbar 13 from both sides to achieve lateral positioning of the crossbar 13. When the synchronous positioning mechanism 9 moves in the opposite direction, the crossbar positioning components 8 are released synchronously to release the positioning.

[0043] Specifically, the crossbar positioning assembly 8 includes a slide block 81 and a side push plate 83. The slide block 81 is slidably connected in the slide groove 74. A connecting seat 82 is installed on the top surface of the slide block 81. The side wall of the connecting seat 82 is fixedly installed with one end of the side push plate 83. The side push plate 83 is slidably connected in the clearance groove opened on the limiting plate 73. A side positioning block 85 is fixedly installed at the end of the limiting plate 73.

[0044] The slide block 81 slides in the slide groove 74, and the side push plate 83 moves synchronously through the connecting seat 82. The side push plate 83 passes through the relief groove of the limiting plate 73, and the side positioning block 85 on its end face directly abuts against the side wall of the crossbar 13 and applies clamping force to achieve lateral clamping and positioning of the crossbar 13. A rubber pad is attached to the contact surface of the side positioning block 85 to prevent indentation on the crossbar 13.

[0045] Furthermore, such as Figure 9As shown, in order to position the top surface of the crossbar 13, the crossbar positioning assembly 8 also includes a pressure plate 84. The limiting plate 73 has a sliding groove 3 842 inside, and the pressure plate 84 is slidably connected in the sliding groove 3 842. The side wall of the pressure plate 84 has an inclined groove 841. The top surface of the side push plate 83 has a sliding groove 2 831 through, and the pressure plate 84 is slidably connected in the sliding groove 2 831. A fixing post 832 is fixed in the sliding groove 2 831, and the fixing post 832 is slidably connected in the inclined groove 841. The pressure plate 84 has an "L" shaped structure, and a rubber pressure post 86 is installed on the bottom surface of the end of the pressure plate 84.

[0046] When the side push plate 83 moves horizontally towards the crossbar 13, the fixed column 832 in the second slide groove 831 moves synchronously. The fixed column 832 slides along the inclined groove 841 of the pressure plate 84. Through the inclined plane transmission, the horizontal movement is converted into the vertical downward movement of the pressure plate 84 along the third slide groove 842, which drives the rubber pressure column 86 to press the top surface of the crossbar 13. When the side push plate 83 retracts, the fixed column 832 slides in the opposite direction, which drives the pressure plate 84 to lift up and release the top surface pressure. Through the inclined groove 841 and the inclined plane of the fixed column 832, vertical positioning is provided, which can prevent the crossbar 13 from moving up and down during the welding process and improve the welding stability.

[0047] Among them, such as Figure 5 - Figure 7 As shown, the synchronous positioning mechanism 9 includes a sliding hole seat 91, a moving rod 92, and a moving frame 93. The sliding hole seat 91 is fixedly installed on both sides of the bottom surface of the crossbar placement platform 7. The moving rod 92 is slidably connected in the sliding hole seat 91. The tail of the moving rod 92 is fixedly installed in the moving frame 93. The two sides of the moving frame 93 are respectively provided with a guide groove 931, a transition groove 932, and a guide groove 933. The guide groove 931 is connected to the guide groove 933 through the transition groove 932. The guide groove 931 is closer to the central axis of the moving frame 93 than the guide groove 933. A sliding column 912 is provided in the guide groove 931, the transition groove 932, and the guide groove 933. The sliding column 912 is fixedly connected to the bottom surface of the slide seat 81.

[0048] When the moving rod 92 slides along the axis of the sliding hole seat 91, it drives the moving frame 93 to move laterally as a whole. When the moving frame 93 moves, the groove walls of the guide groove 931, the transition groove 932, and the guide groove 933 push the sliding column 912 to move along the groove path. Since the guide groove 931 is closer to the central axis of the moving frame 93 and the guide groove 933 is farther away from the central axis, the sliding column 912 drives the sliding seat 81 to move forward and backward along the sliding groove 74 as the groove position changes. As a result, the sliding seat 81 can move closer to or further away from the limiting plate 73, thereby providing clamping force for the crossbar positioning assembly 8.

[0049] Each groove 71 has a movable frame 93 on both sides below it. The two movable frames 93 are fixed with racks 94 on opposite sides. The two racks 94 are connected by gear 2 99. The bottom surface of the crossbar placement platform 7 is equipped with a fixed plate 97. Gear 2 99 is rotatably installed at the center of the fixed plate 97 through a shaft seat.

[0050] The fixing plate 97 is fixed to the bottom surface of the crossbar placement platform 7, providing installation support for the gear 2 99. When one of the movable frames 93 is driven to move, the rack 94 on its side wall drives the gear 2 99 to rotate. The gear 2 99 drives the rack 94 on the other side to move synchronously in the opposite direction through meshing transmission, thereby driving the two movable frames 93 to move synchronously towards or away from each other, realizing the synchronous centering action of the crossbar positioning components 8 on both sides.

[0051] Furthermore, a slide rod 95 is fixed to the side wall of the movable frame 93, and a slide hole seat 98 is slidably connected to the end of the slide rod 95. The slide hole seat 98 is fixedly installed on both sides of the bottom surface of the fixed plate 97. A spring 96 is sleeved on the side wall of the slide rod 95 between the slide hole seat 98 and the movable frame 93. A protrusion 911 is integrally formed on the rack 94 on the side wall of the other movable frame 93. A limit clamp 910 is fixedly installed on the side wall of the fixed plate 97, and the protrusion 911 is slidably connected in the limit clamp 910.

[0052] When the moving frame 93 moves horizontally, the slide bar 95 slides along the sliding hole seat 98 to provide auxiliary guidance for the moving frame 93. The spring 96 is sleeved on the outside of the slide bar 95. When the moving frame 93 is clamped, the spring 96 is compressed and stores elastic potential energy. When the external driving force is released, the spring 96 releases its elastic force to push the moving frame 93 to automatically reset. In addition, the protrusion 911 slides with the moving frame 93 in the limiting clamp 910, which also enables the other moving frame 93 to maintain horizontal movement and prevents the moving frame 93 from shaking and causing the rack to dislodge. The spring 96 also realizes the automatic reset of the moving frame 93.

[0053] Example 2, refer to Figure 10 and Figure 11 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. In order to enable the side plate 11 to approach the crossbar 13, side plate centering positioning components 6 are respectively provided on both sides of the crossbar placement platform 7. The side plate centering positioning components 6 are used to install the side plates 11 on both sides of the ladder cable tray 1. The side plate centering positioning components 6 move towards the crossbar placement platform 7 at the same time and drive the synchronous positioning mechanism 9 to move, so that multiple crossbar positioning components 8 position the crossbar 13. The crossbar 13 slides on the crossbar placement platform 7 due to the contact of the side plate 11. The two ends of each crossbar 13 abut against the inner side wall of the side plate 11. The welding component 5 is used to weld the connection between the crossbar 13 and the side plate 11.

[0054] The side plate centering and positioning components 6 clamp the two side plates 11 of the ladder cable tray 1 respectively, and move towards the crossbar placement platform 7 simultaneously. During the movement of the side plate centering and positioning components 6, the synchronous positioning mechanism 9 is driven to move first, and the crossbar positioning component 8 is driven to pre-position the crossbar 13. Then, the inner wall of the side plate 11 abuts against the end of the crossbar 13, and pushes the crossbar 13 to slide on the sliding roller 72, so that all the crossbars 13 are automatically centered and aligned, and both ends of the crossbar 13 abut against the inner wall of the side plate 11. Finally, the welding component 5 welds the connection between the crossbar 13 and the side plate 11.

[0055] The side plate centering and positioning assembly 6 includes a base plate 61, a centering mechanism 63, and a mounting plate 64. The centering mechanism 63 is slidably connected to the base plate 61 via a guide rail pair 62. The top of the centering mechanism 63 is fixedly mounted with a mounting plate 64 for mounting the side plate 11. A fixing frame 68 is mounted on the bottom surface of the mounting plate 64. The interior of the fixing frame 68 is a cavity 69, and a positioning insertion hole 610 is opened on the axis of the moving rod 92 corresponding to the fixing frame 68. The moving rod 92 is slidably inserted into the positioning insertion hole 610.

[0056] The centering mechanism 63 slides along the base plate 61 via the guide rail pair 62, driving the mounting plate 64 and the fixed frame 68 to move synchronously towards the crossbar placement platform 7. The end of the moving rod 92 is inserted into the positioning hole 610 of the fixed frame 68. When the fixed frame 68 moves with the mounting plate 64, the side wall of the cavity 69 of the fixed frame 68 pushes the moving rod 92 to move axially, thereby triggering the positioning action of the synchronous positioning mechanism 9. The positioning hole 610 can provide positioning function for each crossbar 13 and side plate 11, and can also provide thrust to the moving rod 92 through the fixed frame 68.

[0057] The centering mechanism 63 includes two L-shaped plates 631 and a gear 634. The top of the L-shaped plates 631 is fixed with a mounting block 632, which is mounted on the side wall of the mounting plate 64. The tail side walls of the two L-shaped plates 631 are provided with toothed grooves 633, and the two L-shaped plates 631 are meshed with the side walls of the gear 634 through the toothed grooves 633. The gear 634 is internally keyed with a shaft 635. The bottom end of the shaft 635 is fixedly mounted to the drive motor 67 through a coupling. The top end of the shaft 635 is equipped with a chain sprocket drive component 66. It should be noted that the drive motor 67 is a gear reduction motor with electromagnetic brake, which can simultaneously meet the dual requirements of speed change and locking. The speed change function achieves basic speed reduction and torque increase through the fixed reduction ratio of the gearbox. With the help of frequency conversion control, it can also achieve stepless speed regulation over a wide range. High-speed operation can be used in the fast section of the side plate centering stroke to improve efficiency. When approaching the clamping position, it switches to low-speed slow advance to avoid impacting the workpiece and positioning mechanism. The locking function is achieved by the electromagnetic brake integrated at the tail of the motor. When the power is on, the brake is released and the motor runs normally. When the power is off, the brake locks the motor output shaft, forming a mechanical hard lock. This ensures that the side plate will not rebound due to reaction force after clamping and positioning, and the position is stable and does not move during welding.

[0058] The drive motor 67 drives the shaft 635 to rotate through the coupling. The shaft 635 drives the gear 634 to rotate synchronously. The gear 634 meshes with the tooth grooves 633 of the L-shaped plates 631 on both sides, driving the two L-shaped plates 631 to move synchronously towards or away from each other. The L-shaped plates 631 drive the mounting plates 64 to move synchronously through the mounting blocks 632, realizing the synchronous centering action of the mounting plates 64 on both sides. The power is synchronously transmitted to another centering mechanism 63 through the chain and sprocket transmission component 66, realizing multi-position synchronous drive.

[0059] Example 3, referring to Figure 12 This is the third embodiment of the present invention. This embodiment is based on the first two embodiments. In order to fix the side plate 11 on the mounting plate 64, a fixing member 65 is installed on the side wall of the mounting plate 64. The fixing member 65 includes a clamping plate 651, a threaded rod 652 and a clamping knob 653. The threaded rod 652 is fixedly installed on both side walls of the mounting plate 64. The side wall of the threaded rod 652 is threadedly connected to the clamping knob 653. The clamping knob 653 is rotatably installed on the clamping plate 651 through a bearing 654. The bearing 654 and the clamping plate 651 have sliding holes for the threaded rod 652 to slide.

[0060] After placing the side plate 11 against the side wall of the mounting plate 64, turn the clamping knob 653. The clamping knob 653 moves axially along the threaded rod 652, so that the clamping plate 651 and the mounting plate 64 cooperate to clamp the side wall of the side plate 11, thereby fixing the side plate 11. Turning the clamping knob 653 in the opposite direction will release the clamp and remove the workpiece.

[0061] The above description of the embodiments is only for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
