DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 The utility model provides a technical solution: a liftable welding table for metal parts welding, comprising a box body 1, the upper surface of the box body 1 is open, a protective inner frame 5 is slidably connected to the inner cavity of the box body 1, the upper end of the protective inner frame 5 is fixedly connected to a table plate 4, two groups of adjustment mechanisms 6 are symmetrically arranged on the upper surface of the table plate 4, and welding fixtures 8 are installed on the two groups of adjustment mechanisms 6, and a lifting mechanism 3 is arranged at the bottom of the inner cavity of the box body 1;

[0022] The lifting mechanism 3 includes two groups of first bidirectional screws 32, a first motor 31 and a chain 34. The two groups of first bidirectional screws 32 are rotatably connected to both sides of the inner cavity of the box body 1. One end of the two groups of first bidirectional screws 32 is fixedly connected to a sprocket 33 that is transmission-connected to the chain 34. One end of one group of first bidirectional screws 32 passes through the box body 1 and is driven by the first motor 31. Both ends of the two groups of first bidirectional screws 32 are threadedly connected to a moving block 35. The upper end of the moving block 35 is rotatably connected to a support rod 37. The upper end of the support rod 37 is rotatably connected to a fixed block 39 fixedly connected to the lower surface of the table plate 4.

[0023] The upper end of the support rod 37 is provided with a second fixing pin 38 rotatably connected to the fixed block 39, and the lower end of the support rod 37 is provided with a first fixing pin 36 rotatably connected to the moving block 35. The first fixing pin 36 and the second fixing pin 38 facilitate the rotation of the support rod 37, the moving block 35 and the fixed block 39, and then facilitate the height adjustment of the table plate 4 by changing the angle between the support rod 37 and the horizontal plane. The structure is simple and the equipment cost is reduced.

[0024] A slag trough 9 is provided on the upper surface of the table 4, and the lower end of the slag trough 9 is connected to a bellows 10, and the lower end of the bellows 10 is connected to a guide pipe 11 that passes through the bottom of the box 1. The bellows 10 facilitates the connection between the slag trough 9 and the guide pipe 11 when the table 4 is raised, thereby facilitating the concentration of welding slag generated by welding and facilitating the cleaning of the welding slag.

[0025] The two sides of the outlet pipe 11 are fixedly connected with a bearing stabilizing seat 12, and the outer middle part of the first bidirectional screw 32 is rotatably connected to the inner ring of the bearing stabilizing seat 12. The bearing stabilizing seat 12 improves the stability of the first bidirectional screw 32 during rotation, thereby improving the stability when the table is raised.

[0026] A control panel 2 electrically connected to the first motor 31 is installed on one side of the box body 1. The control panel 2 is electrically connected to the adjustment mechanism 6 and the welding fixture 8 respectively. A plurality of bases 13 are fixedly connected to the lower surface of the box body 1. The control panel 2 is used to conveniently control the operation of the lifting mechanism 3, thereby facilitating the adjustment of the height of the table top to accommodate operators of different heights.

[0027] Both sets of adjustment mechanisms 6 include a cylinder 61 installed on the upper surface of the table 4. The telescopic end of the cylinder 61 is fixedly connected to a moving seat 62. A slide groove 63 is provided on the upper surface of the moving seat 62. Two sets of guide rails 7 for sliding connection of the moving seat 62 are installed on the upper surface of the table 4. The moving seat 62 is pushed and pulled by the cylinder 61 to move on the guide rails 7, thereby facilitating the docking of the metal parts clamped by the welding fixture 8, so as to facilitate the butt welding of the metal parts.

[0028] The welding fixture 8 includes a second bidirectional screw 83 installed in the inner cavity of the slide groove 63 and two groups of guide rods 84. One end of the second bidirectional screw 83 is threadedly connected to a clamping plate 81 that is slidably connected to the two groups of guide rods 84. One end of the second bidirectional screw 83 passes through the movable seat 62 and is driven by a second motor 82. The second bidirectional screw 83 is driven by the second motor 82 to transmit the two groups of clamping plates 81, thereby facilitating the clamping of tubular metal parts and improving the stability of metal part welding.

[0029] During use, the first motor 31 is controlled by the control panel 2 to drive the first bidirectional screw 32 to rotate, and then the sprocket 33 is rotated under the action of the chain 34, and the two groups of first bidirectional screws 32 are synchronously driven to rotate, so as to drive the moving block 35 on the first bidirectional screw 32 to move relatively. When the moving block 35 moves, it is rotationally connected to the lower end of the support rod 37 through the first fixed pin 36. When the inclination angle of the support rod 37 changes, its upper end is rotationally connected to the fixed block 39 through the second fixed pin 38, so that the fixed block 39 drives the table plate 4 to rise, and slides and rises in the inner cavity of the box body 1 through the protective inner frame 5, thereby improving the stability of the table plate 4 when it is raised and lowered, and adapting to operators of different heights to improve convenience, thereby improving the stability of welding of metal parts.
