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.

[0022] like Figure 1-5As shown, the utility model provides a technical solution: an auxiliary clamping device for steel bar welding for construction, comprising a workbench 1, the upper end of the workbench 1 is fixedly connected with a driving adjustment mechanism 7, the lower side of the driving adjustment mechanism 7 is meshed with the rear side of a pushing mechanism 6 for transmission, the lower end of the pushing mechanism 6 is fixedly connected to the upper end of the workbench 1, the front end of the pushing mechanism 6 is fixedly connected to two lower clamping plates 5, the upper ends of the two lower clamping plates 5 are fixedly connected with two T-shaped rods 15, the two T-shaped rods 15 are movably connected with two limiting blocks 16 respectively, the rear ends of the two limiting blocks 16 are fixedly connected with the front end of the driving adjustment mechanism 7, the front ends of the two limiting blocks 16 are fixedly connected to the rear ends of the two upper clamping plates 14 respectively, and the driving adjustment mechanism 7 can drive the two lower clamping plates 5 to move. The limiting block 16 moves downward, which can drive the two upper clamping plates 14 to move downward. In the process of driving the two upper clamping plates 14 to move downward, the two lower clamping plates 5 can be driven to approach each other under the cooperation of the set pushing mechanism 6, and then the two steel bars placed thereon can be driven to approach each other, so that the docking process of the two steel bars can be automatically realized. After the docking of the two steel bars is realized, the driving adjustment mechanism 7 and the pushing mechanism 6 are no longer engaged. At this time, the two upper clamping plates 14 are continued to be driven to move downward through the cooperation between the driving adjustment mechanism 7 and the limiting block 16, and then the steel bars placed on the two lower clamping plates 5 can be further fixed under the cooperation of the set lower clamping plates 5. The upper ends of the two lower clamps 5 are fixedly connected with L-shaped plates 11 on the relatively close sides. The two L-shaped plates 11 are movably connected with four connecting rods 12 through two connecting holes opened at their upper ends. The four connecting rods 12 are grouped in pairs, and their upper ends are fixedly connected to the lower ends of the two pull plates 13 respectively. The four connecting rods 12 are grouped in pairs, and their lower ends are fixedly connected to the upper ends of the two concave frames 9 respectively. The front and rear ends of the two concave frames 9 are movably connected with the front and rear ends of the two rolling pressure rods 8 respectively. Springs 10 are sleeved on the four connecting rods 12. The lower ends of the two lower clamps 5 are fixedly connected with two supporting sleeves 4.

At this time, with the mutual cooperation of the set lower clamping plate 5, the clamping effect of the steel bars placed on the lower clamping plate 5 can be initially achieved. The set rolling pressure rod 8 can not only have a preliminary clamping effect on the steel bars, but also play a buffering role in the process of driving the two steel bars to automatically connect, so that the two steel bars can be smoothly connected together as the two lower clamping plates 5 approach each other, and the mutual cooperation between the set support sleeve 4 and the concave rod 3 can limit the movement direction of the lower clamping plate 5.

[0023] The driving and adjusting mechanism 7 includes an electric hydraulic rod 73, the upper end of which is fixedly connected to the lower end of a top plate 78, and the left and right sides of the lower end of the top plate 78 are movably connected with support plates 1 77, and the two support plates 1 77 are movably connected to the left and right sides of a rotating sleeve 75, respectively. The rotating sleeve 75 is movably connected to an L-shaped rod 1 74 with two guide blocks on two relatively close sides through two guide grooves provided inside it, and the front ends of the two L-shaped rods 1 74 are fixedly connected to the rear ends of two limiting blocks 16, respectively. The left and right ends of the top plate 78 are fixedly connected with limiting blocks 2 76, and the two limiting blocks 2 76 are movably connected to two T-shaped rods 2 71, respectively. The lower ends of the two T-shaped rods 2 71 are fixedly connected to the upper end of the workbench 1, and the top plate 78 is fixedly connected to the upper end of the workbench 1 through a fixed rod provided at its lower end. A tooth plate 72 is fixedly connected, and the tooth plate 72 is meshed with the rear side of the pushing mechanism 6 for transmission. The lower end of the electric hydraulic rod 73 is fixedly connected to the upper end of the workbench 1. The cooperation between the limiting block 2 76 and the T-shaped rod 2 71 can limit the movement direction of the top plate 78. By starting the electric hydraulic rod 73, the top plate 78 is driven to move downward, and then the rotating sleeve 75 can be driven to move downward under the action of the supporting plate 1 77. In the process of driving the rotating sleeve 75 to move downward, the two limiting blocks 16 can be driven downward under the action of the L-shaped rod 1 74. In the process of driving the top plate 78 to move downward, the tooth plate 72 can be driven downward under the action of the fixed rod.

[0024] The pushing mechanism 6 includes a gear 68, which meshes with a toothed plate 72 for transmission. The gear 68 is fixedly connected to the middle position of the polished rod of the worm 62. The worm 62 meshes with two worm wheels 64 for transmission. The two worm wheels 64 are fixedly connected to the rear ends of the two rotating shafts 65, respectively.

The left and right ends are movably connected with support plates three 61, and the lower ends of the two support plates three 61 are fixedly connected to the upper end of the workbench 1. In the process of driving the tooth plate 72 to move downward, the worm 62 can be driven to rotate under the action of the set gear 68. The rotation of the worm 62 can drive the two rotating shafts 65 to rotate under the action of the set worm wheel 64, and the two rotating shafts 65 turn in opposite directions. Through the rotation of the two rotating shafts 65, the two lower clamping plates 5 can be driven to move closer to each other to a certain distance under the cooperation between the set pushing frame 69 and the L-shaped plate two 66, until the two steel bars placed thereon can be completely butt-jointed together, and after the two lower clamping plates 5 move closer to each other to a certain distance, the tooth plate 72 and the gear 68 are no longer meshing.

[0025] The operating steps of the utility model are:

[0026] When the device is used to assist in clamping the steel bars, first pull the two pull plates 13 to drive the two concave frames 9 and the two rolling pressure rods 8 to move upward under the action of the provided connecting rod 12, then place the two steel bars to be welded on the two lower clamping plates 5 respectively, and then release the pull plates 13. At this time, the two concave frames 9 can be driven to move downward under the action of the provided spring 10, and then the two rolling pressure rods 8 can achieve a preliminary clamping effect on the two steel bars, and then the electric hydraulic rod 73 is started to drive the top plate 78 to move downward, and then the two upper clamping plates 14 can be driven to move downward under the cooperation between the provided rotating sleeve 75, the L-shaped rod 74 and the limiting block 16. The two upper clamping plates 14 are moved downward, and the worm 62 can be driven to rotate under the action of the toothed plate 72 and the gear 68. The rotation of the worm 62 can drive the two lower clamping plates 5 to approach each other to a certain distance under the cooperation of the worm wheel 64, the rotating shaft 65, the pushing plate 67, the pushing frame 69 and the L-shaped rod 66. Then, under the action of the two rolling pressure rods 8, the two steel bars can be driven to approach each other until they are fully docked. At this time, the toothed plate 72 and the gear 68 are no longer engaged. Then, as the two upper clamping plates 14 continue to move downward, the two lower clamping plates 5 can cooperate with each other to further clamp and fix the two docked steel bars.
