[0023] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] like Figure 1 - Figure 8 The shown type of cable tray manufacturing welding forming fixture includes an operating frame 2, which includes an equipment bin and a bottom bin. The equipment bin is located above the bottom bin, and a support leg 1 is fixedly installed at the front end of the bottom bin. Two main frames 3 are symmetrically arranged on the top of the support leg 1, and the surface of the main frame 3 is provided with a bridge frame side plate 4. The bridge frame side plate 4 passes through the bottom bin and is slidably arranged on the surface of the main frame 3. A driving mechanism 5 is installed in the middle of the support leg 1, and the driving mechanism 5 is located below the main frame 3. Connecting rod mechanisms 6 are installed on both sides of the support leg 1, and a swing mechanism 7 is provided inside the equipment bin. A lower material bin 8 is provided above the support leg 1, and a cross bar is provided inside the lower material bin. The cross bar cooperates with the two bridge frame side plates 4, and the connecting rod mechanism 6 and the swing mechanism 7 can continuously transport the cross bar between the two bridge frame side plates 4, which is convenient for continuous welding work. Under the action of the driving mechanism 5, the bridge frame side plates 4 can be pushed step by step to realize a continuous welding process, which greatly improves production efficiency and has a high degree of automation.

[0026] The driving mechanism 5 includes a rotating cylinder 9, which is located below the main frame 3. Connecting columns 10 are fixedly installed at both ends of the rotating cylinder 9. The connecting columns 10 rotate and penetrate the support legs 1. A second gear 14 is provided on the surface of the rotating cylinder 9. A motor bracket 11 is installed on the side of the rotating cylinder 9. A stepping motor 12 is installed on the top of the motor bracket 11. A first gear 13 is installed on the output end of the stepping motor 12. The first gear 13 is meshed with the second gear 14. Two swing arms 15 are symmetrically installed on the surface of the rotating cylinder 9. The first gear 13 is driven to rotate by the stepping motor 12, and then the first gear 13 is meshed with the second gear 14. The second gear 14 will drive the rotating cylinder 9 to rotate. While the rotating cylinder 9 rotates, the connecting column 10 will drive the turntable 16 to rotate, and the swing arm 15 will also rotate synchronously. When the welding arm welds the cross bar between the two bridge side plates 4, the swing arm 15 can push the cross bar forward to realize the stepping movement operation of the bridge side plates 4, and the rotation of the turntable 16 can drive the connecting rod mechanism 6 to operate.

[0027] The connecting rod mechanism 6 includes a turntable 16, which is fixedly mounted on the end of the connecting column 10. A protruding column 17 is installed on the end surface of the turntable 16. A bracket 20 is fixedly mounted on the outside of the bottom bin. A sleeve 21 is installed at one end of the bracket 20 close to the turntable 16. A polished rod 19 is slidably mounted inside the sleeve 21. A connecting ring 18 is sleeved on the outside of the protruding column 17. The end of the polished rod 19 is fixedly connected to the connecting ring 18. The turntable 16 rotates to drive the protruding column 17 to rotate. Under the action of the connecting ring 18, the rotational motion of the turntable 16 is converted into a linear motion of the polished rod 19. The other end of the optical rod 19 is provided with a connecting frame 22, and the inner wall of the equipment bin is penetrated by a path groove 24. A movable block 26 is movably provided inside the equipment bin. A guide rod 25 is penetrated in the middle of the movable block 26, and the end of the guide rod 25 movably penetrates the path groove 24. A connecting rod 23 is connected between one end of the guide rod 25 protruding from the operating frame 2 and the connecting frame 22 through a rotating shaft. When the optical rod 19 reciprocates in a straight line, the connecting rod 23 will drive the guide rod 25 to move up and down along the path groove 24, and the movable block 26 will move synchronously with the guide rod 25.

[0028] The swing mechanism 7 includes a sleeve 29, which is rotatably mounted inside the equipment compartment. A first swing plate 30 and a second swing plate 32 are fixedly mounted on the surface of the sleeve 29. When the end of the first swing plate 30 moves upward, the end of the second swing plate 32 moves downward. When the end of the first swing plate 30 moves downward, the end of the second swing plate 32 moves upward. The first swing plate 30 is arranged inside the equipment compartment, and the second swing plate 32 is arranged on the outside of the operating frame 2. A movable column 31 is provided at the end of the first swing plate 30. Two side plates 27 are symmetrically mounted on the surface of the movable block 26 near the first swing plate 30. The two side plates 27 are respectively arranged on both sides of the first swing plate 30. A sliding groove 28 is opened on the surface of the side plate 27. The surface of the movable column 31 is slidably mounted in the sliding groove 28 and is movably inserted into the interior of the sliding groove 28 through the movable column 31. When the movable block 26 moves up and down inside the equipment compartment, the end of the first swing plate 30 will move synchronously with the movement of the movable block 26.

[0029] A card slot is provided at the end of the second swing plate 32, a baffle 33 is fixedly installed on the top of the card slot, an extrusion plate 34 is installed on the bottom of the card slot through a torsion spring, an arc groove 35 is provided on the surface of the extrusion plate 34, a limit frame 36 is installed on the top of the outlet of the lower bin 8, a protruding plate is provided on the surface of the limit frame 36, a through groove 38 is provided on the surface of the protruding plate, a Z-shaped plate 39 is slidably installed inside the through groove 38, two plug-in columns 37 are symmetrically provided on the top of the limit frame 36, the surface of the plug-in column 37 is movable through the top of the Z-shaped plate 39, and a tension spring is connected between the top of the Z-shaped plate 39 and the plug-in column 37. When the end of the plate 32 moves upward, the baffle 33 can first push the Z-shaped plate 39 upward, so that the outlet of the lower material bin 8 is in an open state, and then the extrusion plate 34 will be squeezed by the bottom end of the lower material bin 8, so that the extrusion plate 34 is in an open state. At this time, the cross bar inside the lower material bin 8 will roll into the slot. When the end of the second swing plate 32 moves downward, the elastic force of the torsion spring will displace the end of the extrusion plate 34 toward the baffle 33. The extrusion plate 34 has a squeezing and fixing effect on the cross bar inside the slot. At this time, the elastic force of the tension spring can reset the Z-shaped plate 39, so that under normal circumstances, the outlet of the lower material bin 8 is in a closed state.

[0030] The protruding column 17 and the swing arm 15 are in the same straight line. After the cross bar is welded, the swing arm 15 can push the welded cross bar during the rotation process, thereby realizing the step-by-step movement of the cable tray.

[0031] There are multiple positioning arc grooves evenly opened on the surface of the bridge side plate 4, which cooperate with the cross bar. When the two ends of the cross bar are respectively engaged in the positioning arc grooves on the surface of the two bridge side plates 4, the welding arm on the side of the support leg 1 can weld and fix it to complete the welding of the cable bridge.

[0032] Working principle: First, the staff slides the two bridge side plates 4 through the bottom bin and sets them on the surface of the two main frames 3 respectively, and then drives the first gear 13 to rotate through the stepping motor 12, and the first gear 13 drives the second gear 14 to rotate. At this time, the rotating cylinder 9 will rotate counterclockwise. When the rotating cylinder 9 rotates, the protruding column 17 will also rotate. Under the action of the connecting ring 18, the rotational motion of the turntable 16 is converted into a linear reciprocating motion of the polished rod 19. When the protruding column 17 rotates to the front of the turntable 16, the polished rod 19 moves forward as a whole, and under the action of the connecting rod 23 , the movable block 26 will move to the bottom of the equipment bin, and the end of the first swing plate 30 will also drop to the lowest point, and the end of the second swing plate 32 will move upward, and the baffle 33 can push the Z-shaped plate 39 upward, so that the outlet of the lower bin 8 is in an open state, and the next step is that the extrusion plate 34 will be squeezed by the bottom end of the lower bin 8, so that the extrusion plate 34 is in an open state, and the cross bar inside the lower bin 8 will roll into the slot, and when the protruding column 17 rotates to the rear of the turntable 16, the light rod 19 moves backward as a whole, and under the action of the connecting rod 23, the movable block 26 will move to the equipment bin. The top of the preparation bin, at the same time, the end of the first swing plate 30 will also be lifted, and the end of the second swing plate 32 will move downward, and the elastic force of the torsion spring will displace the end of the extrusion plate 34 in the direction of the baffle 33, and the extrusion plate 34 has a squeezing and fixing effect on the cross bar inside the slot. At this moment, the elastic force of the tension spring can reset the Z-shaped plate 39, so that the outlet of the lower bin 8 is in a closed state under normal conditions, and at this moment, the end of the second swing plate 32 will be parallel to the two bridge side plates 4, and the two ends of the cross bar inside the slot will be respectively clamped in the positioning arc grooves on the surfaces of the two bridge side plates 4. The downward pressure at the end of the swing plate 32 can position the cross bar, ensuring that the cross bar will not shake during the welding process, thereby improving the welding quality. Subsequently, the welding arm on the side of the leg 1 can weld and fix it to complete the welding of the cable tray. Finally, the turntable 16 continues to rotate. After the cross bar is fixedly welded between the two bridge side plates 4, the end of the second swing bar 32 moves upward. At this time, the cross bar directly above the rotating cylinder 9 is fixedly welded to the bridge side plate 4, so that during the rotation of the swing arm 15, the newly welded cross bar will be pushed forward to realize the step-by-step advancement of the cable tray.
