DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following further describes the present utility model with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the drawings is for better explanation, and the structure of the present utility model necessarily goes beyond these limited embodiments. For some equivalent replacement schemes or common means, no detailed description will be given herein, but they still fall within the protection scope of the present application.

[0024] Figures 1 - 4 is the best embodiment of the present utility model. The following further describes the present utility model with reference to the attached Figures 1 - 4 drawings.

[0025] Refer to the attached Figures 1 - 4, The utility model discloses a welding auxiliary device for the side plate of a cable branch box, which includes a frame, a welding table 1 and a bottom plate 2. The bottom plate 2 is movably arranged on the upper side of the frame, and the welding table 1 is installed on the bottom plate 2. It also includes a height adjustment mechanism and a rotation adjustment mechanism. The height adjustment mechanism is arranged between the frame and the bottom plate 2 and pushes the bottom plate 2 to rise and fall. The rotation mechanism is located between the bottom plate 2 and the welding table 1 and drives the welding table 1 to rotate.

[0026] There are two height adjustment mechanisms symmetrically arranged at both ends of the bottom plate 2. The two height adjustment mechanisms work independently. When the two height adjustment mechanisms work synchronously, they can adjust the height of the welding table 1. When the two height adjustment structures work out of sync, they can adjust the tilt angle of the welding table 1.

[0027] The height adjustment mechanism includes a support rod 4, a fixed rod 5, a guide wheel 6 and an electric telescopic rod 8. The fixed rod 5 is located under the bottom plate 2. One end of the fixed rod 5 is rotatably installed with a guide wheel 6 and is slidably connected to the frame through the guide wheel 6. One end of the support rod 4 is rotatably connected to the fixed rod 5, and the other end is rotatably connected to the bottom plate 2. The electric telescopic rod 8 is rotatably installed on the frame, and the movable end of the electric telescopic rod 8 is rotatably connected to the support rod 4 or the fixed rod 5.

[0028] In this embodiment, the fixed rod 5 is vertically arranged. The upper end of the fixed rod 5 is rotatably connected to the support rod 4, and the lower end is rotatably installed with a guide wheel 6.

[0029] In order to ensure the stable operation of the height adjustment mechanism, a limit mechanism is arranged between the fixed rod 5 and the frame so that the fixed rod 5 can only move linearly and cannot rotate.

[0030] The limit mechanism includes a limit block 18 fixed on one side of the fixed rod 5 and a limit groove 19 arranged on the frame. The limit block 18 is a rectangular block, and the limit block 18 is slidably arranged in the limit groove 19. When the fixed rod 5 moves, the limit block 18 cooperates with the limit groove 19 to ensure that the fixed rod 5 can only move along the limit groove 19 and cannot rotate.

[0031] The rotation adjustment mechanism is arranged between the welding table 1 and the bottom plate 2 and is used to adjust the rotation of the welding table 1. The rotation adjustment mechanism includes a worm gear 13 and a worm 14. The worm gear 13 is meshed with the worm 14. The worm 14 is rotatably installed at the bottom of the bottom plate 2, and the worm gear 13 is fixedly connected to the welding table 1.

[0032] Specifically, the frame includes a base 11 arranged under the bottom plate 2 and a connecting frame 10. The base 11 is a trough-shaped with an upward opening. The connecting frame 10 is fixedly installed on the top of the base 11. The connecting frame 10 is a cuboid frame. One end of the connecting frame 10 is installed with a control device 17 for controlling the action of the electric telescopic rod 8. In this embodiment, the control device 17 is a PLC controller.

[0033] In this embodiment, there are two support rods 4 and two fixed rods 5 for each height adjustment mechanism. The two fixed rods 5 are arranged on both sides of the frame. A first connecting shaft 7 is arranged between the two fixed rods 5. The two ends of the first connecting shaft 7 are respectively rotatably connected to the tops of the corresponding fixed rods 5 on the two sides. The upper ends of the two support rods 4 are respectively rotatably connected to both sides of the bottom plate 2, and the lower ends of the two support rods 4 are both rotatably connected to the first connecting shaft 7. The movable end of the electric telescopic rod 8 is rotatably connected to the middle of the first connecting shaft 7.

[0034] Guide wheels 6 are rotatably installed at the lower ends of the fixed rods 5. Guide grooves 12 are arranged on both sides of the top of the connecting frame 10. The guide wheels 6 are respectively arranged in the corresponding guide grooves 12 and can move along the guide grooves 12.

[0035] A second connecting rod 9 is arranged in the middle of the base 11. The two electric telescopic rods 8 are rotatably installed on the second connecting rod 9. In order to avoid interference between the two electric telescopic rods 8, the two electric telescopic rods 8 are arranged side by side along the axis of the second connecting rod 9.

[0036] When adjusting the height, the electric telescopic rod 8 is controlled to act by the control device 17. The two electric telescopic rods 8 are controlled separately. When the two electric telescopic rods 8 act synchronously, they push the first connecting shafts 7 on both sides to drive the fixed rods 5 at both ends to move horizontally synchronously. The guide wheels 6 move in the guide grooves 12, and the limit blocks 18 slide in the limit grooves 19, so that the first connecting shafts 7 on both sides approach or move away from each other, and then the inclination angles of the support rods 4 on both sides are changed, realizing the height adjustment of the welding table 1 up and down, facilitating the adjustment of the height of the welding table 1 according to the needs of the welding personnel, assisting welding, improving the comfort of welding, and having high adaptability.

[0037] When adjusting the inclination angle, only the electric telescopic rod 8 on one side can be made to act. The electric telescopic rod 8 pushes the first connecting shaft 7 on the corresponding side to move, so that the inclination angle of the support rod 4 on that side is changed, causing one end of the bottom plate 2 and the welding table 1 to rise or fall, realizing the adjustment of the inclination angle of the bottom plate 2 and the welding table 1 thereon, and assisting welding.

[0038] After the angle adjustment is completed, by making the two electric telescopic rods 8 act synchronously, the height of the welding table 1 in the inclined state can be adjusted, making the welding table 1 have good adaptability.

[0039] Specifically, limit angle blocks 3 are fixedly arranged at the four corners above the welding table 1 for limiting the cable distribution box. During the inclination and rotation of the welding table 1, the positions of the cable distribution box and its side plates can be limited. The limit angle blocks 3 are in a right-angled shape. A round table is fixedly arranged in the middle of the lower side of the welding table 1. The round table rotatably passes through the bottom plate 2 and is fixedly connected to the worm wheel 13.

[0040] Handwheels 15 are fixedly installed at both ends of the worm 14. The handwheels 15 are located on one side of the bottom plate 2. An installation seat 16 is arranged at the bottom of the bottom plate 2. The worm 14 is rotatably installed on the installation seat 16.

[0041] In this embodiment, according to the needs of the welding operator, the welding table 1 can be rotationally adjusted, so that the welding operator can weld at multiple positions on the side plate of the cable distribution box without rotating around the welding table 1.

[0042] When adjustment is needed, rotate the handwheel 15. The handwheel 15 drives the worm 14 to rotate, and then drives the worm gear 13 to rotate. The worm gear 13 drives the welding table 1 to rotate through the frustum. After reaching the required position, stop rotating the handwheel 15.

[0043] During use, according to the needs of the welding operator, the two electric telescopic rods 8 operate simultaneously. The fixed rods 5 at both ends are driven to move simultaneously through the connecting shafts 7 on both sides. The guide wheels 6 move in the guide grooves 12, and the limit blocks 18 slide in the limit grooves 19, so that the connecting shafts 7 on both sides approach or move away from each other, raising or lowering the welding table 1.

[0044] Only operate one side of the electric telescopic rod 8 to push the corresponding connecting shaft 7 on that side to move, so that the inclination angle of the support rod 4 on that side changes, raising or lowering one end of the bottom plate 2 and the welding table 1, and adjusting the inclination angle of the bottom plate 2 and the welding table 1 thereon.

[0045] During the welding process, the handwheel 15 can also be rotated, so that the worm 14 drives the worm gear 13 to rotate, and then drives the welding table 1 to rotate. The above process is used to assist the welding operator in welding the side plate of the cable distribution box. The operation is simple and easy to implement.

[0046] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution content of the present invention still belong to the protection scope of the technical solution of the present invention.
