Description

Technical Field

[0001] This invention relates to the field of cable tray processing equipment technology, and in particular to a welding fixture for a mesh cable tray. Background Technology

[0002] Cable trays are devices used to manage and secure cables and wires, widely used in data centers, computer rooms, communication base stations, industrial control systems, and other applications. Their main function is to keep cables neat and organized, facilitating maintenance and management, while also preventing excessive bending, tangling, or damage. Cable trays come in various forms; among them, mesh cable trays are an open-structure design widely used in data centers, industrial facilities, office buildings, and other locations. Composed of a metal mesh, they offer good ventilation, flexible installation, and convenient maintenance, making them suitable for applications requiring efficient cable management and heat dissipation.

[0003] A mesh cable tray is formed by welding multiple long main poles and multiple secondary poles together. When welding a mesh cable tray, the long main poles need to be fixed in relative positions, and then the secondary poles are placed between the main poles. The main poles and secondary poles are then welded together using welding equipment. However, depending on the mesh size and the length of the secondary poles of different mesh cable trays, the welding personnel need to adjust the distance between the main poles. After adjustment, the welding personnel also need to perform tooling clamping operations, which increases the complexity of the welding operation. Summary of the Invention

Detailed Implementation

[0028] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

[0029] The left, right, up, and down positions of the various components shown in the attached diagram are just one arrangement method; the specific positions should be set according to specific needs.

[0030] In one embodiment, such as Figures 1-5As shown, a wire mesh wiring frame welding fixture includes a base 100 fixed on a welding device and a fixture support frame 200 for supporting a reference main rod. A flipping drive unit 500 is provided on the base 100, and the end of the fixture support frame 200 facing the base 100 is connected to the flipping drive unit 500. The flipping drive unit 500 can drive the fixture support frame 200 to rotate around its connection point with the flipping drive unit 500. The fixture support frame 200 is provided with multiple sliding fixture clamping structures. Each fixture clamping structure includes a clamping switching assembly 600 and two supporting clamping assemblies 300. The two supporting clamping assemblies 300 are slidably mounted on the fixture support frame 200 and each supporting clamping assembly 300 includes a sliding part 310 and a clamping part. The sliding part 310 slides on the fixture support frame 200. On the slide 310, the clamping part is provided on the slide 310. The lower end of the clamping part can be detachably connected to the tooling support frame 200. When the lower end of the clamping part is connected to the tooling support frame 200, the lower end of the clamping part can restrict the movement of the supporting clamping assembly 300 on the tooling support frame 200 and the clamping part is in a clamped state. When the lower end of the clamping part is separated from the tooling support frame 200, the lower end of the clamping part no longer restricts the movement of the supporting clamping assembly 300 on the tooling support frame 200 and the clamping part is in a released state. The clamping switching assembly 600 is provided between the two supporting clamping assemblies 300 and the end of the clamping switching assembly 600 is connected to both the slide 310 and the clamping part. The clamping switching assembly 600 adjusts the connection state between the lower end of the clamping part and the tooling support frame 200 by acting on the lower end of the clamping part.

[0031] In this embodiment of the invention, in the initial state, the lower ends of the clamping parts in the support and clamping assembly 300 are all separated from the tooling support frame 200 and the clamping parts are also in a loose state. At this time, according to the width requirements of the mesh cable tray, the positions of multiple tooling clamping structures on the tooling support frame 200 are adjusted to adjust the distance between two adjacent tooling clamping structures. The reference main rod of the mesh cable tray is placed on the corresponding support and clamping assembly 300, with the reference main rod inside the clamping part. The clamping switching assembly 600 starts working and drives the lower end of the clamping part. The clamping part begins to perform a clamping action on the reference main rod, and the lower end of the clamping part gradually connects with the tooling support frame 200. When the lower end of the clamping part is connected with the tooling support frame 200, the entire support... The clamping assembly 300 is fixed on the tooling support frame 200 and kept in a stable state. At the same time, the clamping part clamps the reference main rod, ensuring that the reference main rod remains stable when welding the wire mesh cable tray. The two supporting clamping assemblies 300 in the tooling clamping structure clamp the reference main rod at two positions, which can ensure the installation direction of the reference main rod so that multiple reference main rods remain parallel after installation. After the upper surface welding of the reference main rod and the auxiliary rod in the cable tray is completed, the flipping drive unit 500 works and drives the tooling support frame 200 to rotate around the end connected to the flipping drive unit 500, so that the tooling support frame 200 gradually rotates to a vertical state, and then the lower side of the cable tray rotates to face forward, which facilitates the welding personnel or welding equipment to weld the other side of the cable tray.

[0032] In one embodiment, such as Figures 1-3 As shown, the tooling support frame 200 includes an outer connecting part 220 and two parallel guide arms 210. The two guide arms 210 are arranged opposite each other, and one end of the guide arms 210 is connected to the flipping drive part 500. The other ends of the two guide arms 210 are connected together through the outer connecting part 220. At least one support foot 240 is provided on the outer connecting part 220, and the bottom of the support foot 240 has a flat foot pad. In this embodiment of the invention, the two guide arms 210 are respectively connected to a support and clamping component 300 in the tooling clamping structure to provide support and guidance. The outer connecting part 220 connects the two guide arms 210 together to maintain their rotation synchronicity. The support foot 240 on the outer connecting part 220 can be placed on a welding table or the ground to support the end of the tooling support frame 200 away from the flipping drive part 500, thereby improving the support strength of the entire tooling support frame 200.

[0033] In one embodiment, such as Figures 1-5As shown, the bottom of the guide arm 210 is provided with a blocking rod 230 along its length. The clamping part includes two clamping actuation units 320, a lower rotating shaft 330, and an extension connecting rod 350. The two clamping actuation units 320 are slidably disposed on the upper end face of the slide block 310 in a relative manner. The lower rotating shaft 330 is rotatably disposed on the bottom of the slide block 310. A brake sleeve 340 is located in the middle of the lower rotating shaft 330. One end of the extension connecting rod 350 is fixedly connected to the brake sleeve 340, and the other end is connected to the clamping switching assembly 600. The clamping switching assembly 600 can cause the lower rotating shaft 330 and the brake sleeve 340 to rotate by acting on the extension connecting rod 350. The two ends of the lower rotating shaft 330 have opposite helical directions. The two clamping actuation units 320... The bottom of the brake sleeve 340 is connected to the spiral portions at both ends of the lower rotating shaft 330; the side of the brake sleeve 340 is detachably connected to the blocking rod 230; in this embodiment of the invention, the clamping switching assembly 600 works and acts on the extension connecting rod 350, the extension connecting rod 350 is pushed and pulled by the clamping switching assembly 600 to drive the brake sleeve 340, the brake sleeve 340 and the extension connecting rod 350 rotate, the side of the rotating brake sleeve 340 can switch between a separated state and a connected state with the blocking rod 230; the rotating blocking rod 230, through the cooperation of the spiral section at its end with the bottom of the clamping execution unit 320, makes the two clamping execution units 320 move synchronously and move towards or away from each other, so as to realize the clamping and releasing of the reference main rod by the two clamping execution units 320.

[0034] In one embodiment, such as Figures 1-5 As shown, at least one brake pad 360 is provided on the outer wall of the brake sleeve 340 facing the blocking rod 230. Multiple brake grooves are evenly distributed on the side of the blocking rod 230 facing the brake sleeve 340. The brake pad 360 can rotate into the brake groove. In this embodiment, rotation of the brake sleeve 340 can drive the brake pad 360 to rotate. The rotating brake pad 360 can rotate into or out of the brake groove. When the brake pad 360 is in the brake groove, the side of the brake groove can prevent the brake pad 360 from moving along the blocking rod 230. This restricts the movement of the entire support and clamping assembly 300 on the tooling support frame 200. When the brake pad 360 disengages from the brake groove, the blocking rod 230 disengages from the brake pad 360, and the support and clamping assembly 300 can slide on the tooling support frame 200 to adjust the distance between two adjacent reference main rods. When the brake pad 360 rotates into the brake groove, the two clamping execution units 320 have not completed clamping, and the brake pad 360 has already entered the brake groove. Thus, the reference main rod can be picked up and put down while restricting the movement of the support and clamping assembly 300 on the tooling support frame 200.

[0035] In one embodiment, such as Figures 1-5As shown, the upper surface of the slide block 310 has two guide slots 311. The clamping execution unit 320 includes a clamping plate 321, a lower clamping support arm 322, and a clamping slider 323. The clamping slider 323 is slidably installed in the corresponding guide slots 311. The clamping plate 321 is fixed to the upper side of the clamping slider 323, and the top edge of the clamping plate 321 is bent outward. The surface of the clamping plate 321 also has multiple clamping strips 324. One end of the lower clamping support arm 322 is fixedly connected to the clamping slider 323, and the other end is engaged with the helical section of the lower rotating shaft 330. In this embodiment of the invention, through the cooperation between the helical section of the lower rotating shaft 330 and the lower clamping arm 322, and the sliding restriction of the clamping slider 323 in the guide groove 311, the rotating lower rotating shaft 330 can drive the clamping plate 321 to move on the upper surface of the slide block 310, so as to realize the clamping and loosening of the reference main rod; the clamping bar 324 can improve the clamping firmness by increasing the friction with the side wall of the reference main rod, and the top edge of the clamping plate 321 is bent outward, so that the top of the two clamping plates 321 is in an open state, which makes it easy for the reference main rod to be accurately placed between the two clamping plates 321.

[0036] In one embodiment, such as Figures 1-6 As shown, the extension link 350 has a rod-frame structure. The clamping switching assembly 600 includes a horizontal rod 610, a switching movable rod 620, and a switching cylinder 630. Both ends of the horizontal rod 610 are fixedly connected to the sides of two corresponding sliding blocks 310. The switching movable rod 620 is located below the horizontal rod 610 and has at least one guide sleeve 640 that can be slidably fitted onto the horizontal rod 610. Switching action rods 650 are provided at both ends of the switching movable rod 620, and the switching action rods 650 are inserted into the corresponding extension link 350. A switching cylinder 630 is also provided on the lower end face of the horizontal rod 610. One end is connected to the switching actuator 620; in this embodiment of the invention, the switching cylinder part 630 can drive the switching actuator 620 to move along the direction of the horizontal rod 610 through its own telescoping property. The moving switching actuator 620 acts on the corresponding extension link part 350 through the switching action rod 650. The switching action rod 650 pushes and pulls the extension link part 350. Under the restriction of the brake sleeve 340 and the lower rotating shaft 330, the extension link part 350 can drive the brake sleeve 340 and the lower rotating shaft 330 to rotate, so as to realize the clamping and releasing of the clamping actuator 320 on the reference main rod, and adjust the separation state and connection state of the brake sleeve 340 and the blocking rod 230.

[0037] In one embodiment, such as Figures 1-6As shown, the crossbar 610 is also provided with two support points, which are located at both ends of the crossbar 610. Each support point includes a calibration fulcrum 660 and a contact plate 670 located on top of the calibration fulcrum 660. The calibration fulcrum 660 is an elastic telescopic rod, and the surface of the contact plate 670 has pressure sensing plates. When the reference main rod is placed on the support clamping assembly 300, the upper surface of the contact plate 670 abuts against the lower surface of the reference main rod, and both pressure sensing plates generate sensing signals. At this time, the reference main rod is in a horizontal state, which facilitates accurate welding in the future.

[0038] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, the flip drive unit 500 includes a flip spindle 510, a flip motor 520, and a check component. The two ends of the flip spindle 510 are rotatably connected to the base 100 via supports. The output end of the flip motor 520 is connected to one end of the flip spindle 510. The end of the tooling support frame 200 near the flip drive unit 500 is fixedly connected to the flip spindle 510. The check component is located on the base 100 and connected to the flip spindle 510. The check component can lock the flip spindle 510 and prevent it from rotating. In this embodiment, the flip motor 520 operates and drives the flip spindle 510 to rotate. The flip spindle 510 drives the tooling support frame 200 to rotate, adjusting the tilt angle of the tooling support frame 200 to facilitate welding of the mesh cable tray. When the flip spindle 510 rotates, the check component acts on the flip spindle 510 and locks it, ensuring the stability of the tooling support frame 200 when it rotates to a vertical position.

[0039] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8As shown, the rotating spindle 510 is provided with at least one extension 530. The anti-return component includes an anti-return movable rod frame 540, an arched plate 580, and multiple anti-return blocks 560. The anti-return movable rod frame 540 is slidably mounted on the base 100, and one end of the anti-return movable rod frame 540 is connected to the support via a self-locking spring part 550. Multiple anti-return blocks 560 are provided on the anti-return movable rod frame 540, and two adjacent anti-return blocks 560 form a clearance opening. The arched plate 580 is provided at one end of the anti-return movable rod frame 540, and the arched plate... The outer wall of the arched plate 580 has an axial groove 590. A top roller 511 is provided at the end of the rotating main shaft 510 near the arched plate 580. The top roller 511 rolls in contact with the outer wall of the arched plate 580. A handle 570 is also provided on the anti-return movable rod frame 540. In this embodiment of the invention, in the initial state, the extension 530 is opposite to the clearance opening and the top roller 511 is located in the middle of the arched plate 580. When the rotating main shaft 510 rotates, the extension 530 passes through the clearance opening, and simultaneously, the top roller 511 rotates with the rotating main shaft 510. As the push roller 511 gradually rotates to the side of the arched plate 580, the anti-return movable rod 540 moves along the length of the base 100 under the elastic force of the self-locking spring 550. Therefore, the anti-return block 560 moves to a position opposite to the extension 530, thus preventing the extension 530 from rotating, thereby locking the rotating spindle 510 and ensuring the stability of the tooling support frame 200. After the cable tray welding is completed, pulling the handle 570 moves the anti-return movable rod 540 along the base 100 and the anti-return block 560 moves. The tooling support frame 200 is rotated to a position that is misaligned with the extension 530, thereby releasing the restriction on the rotating spindle 510 and allowing the rotating motor 520 to drive the rotating spindle 510 to rotate back to a horizontal state. The handle 570 is released, the anti-return movable rod 540 moves back, and the arched plate 580 is blocked by the top roller 511. The top roller 511 is located in the axial groove 590, which can limit the rotation of the top roller 511 and the rotating spindle 510 to a certain extent, so as to ensure the stability of the tooling support frame 200 after it is in a horizontal state.

[0040] The above embodiment provides a welding fixture for a mesh cable tray. In the initial state, the welder can adjust the position of the two supporting clamping components 300 on the guide arm rod 210 through the clamping switching component 600, and then adjust the position of the reference main rod according to the mesh size requirements of the cable tray. The reference main rod is placed on the fixture clamping structure, with the reference main rod between the two clamping execution units 320. The switching cylinder part 630 works and drives the crossbar 610 to move along the length direction of the crossbar 610. The switching movable rod 620 drives the switching action rod 650 to move, and the switching action rod 650 pushes the extension connecting rod part 350, thereby rotating the brake sleeve 340 and the lower rotating shaft 330. The rotating brake sleeve 340 causes it to rotate. The surface brake pad 360 gradually rotates into the brake groove on the blocking rod 230 to restrict the movement of the entire supporting clamping assembly 300; the rotating lower shaft 330, through the helical sections at both ends, engages with the helical sections at the bottom of the two clamping actuators 320, allowing the two clamping actuators 320 to approach each other and clamp the reference main rod; the welder places the auxiliary rod between the reference main rods and welds them to form a mesh-type cable tray; after the upper side of the mesh-type cable tray is welded, the flipping drive unit 500 drives the tooling support frame 200 to rotate upward so that the tooling support frame 200 rotates to a horizontal state, so that the welder can weld the unwelded side of the mesh-type cable tray to ensure the strength of the weld. The reference main rod and auxiliary rod of the cable tray in this invention are not limited to rectangular tubes, but can also be long strip components such as round thin tubes, C-shaped grooves, and thick steel wires.
