Description

Technical Field

[0001] This utility model relates to the field of steel grating processing technology, specifically a clamping device for steel grating welding processing. Background Technology

[0002] Steel grating, also known as steel grid, is a steel product made by arranging flat steel bars at certain intervals and crossbars and welding them together to form square grids in the middle. It is mainly used as drainage ditch covers, steel structure platform panels, and steel stair treads. The crossbars are generally made of twisted square steel, and during processing, a pressing method is often used for vertical welding of the edges.

[0003] Currently, before welding steel gratings, workers need to load the flat steel bars, and then place the crossbars on top of multiple flat steel bars. The crossbars and flat steel bars are then hot-pressed and welded together with the help of a hot-press welding mechanism. However, the crossbars and flat steel bars are prone to shaking during processing, which can cause the crossbars to shift and thus reduce the quality of the finished steel gratings during welding. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping device for steel grating welding, which solves the problem that before welding, workers need to load the flat steel into the steel grating, and place the crossbar on top of multiple flat steels. Then, with the cooperation of the hot-press welding mechanism, the crossbar and flat steel are hot-pressed and welded. However, the crossbar and flat steel are prone to shaking during processing, which causes the crossbar to shift and thus leads to a decrease in the quality of the finished steel grating during welding.

[0005] This application provides a clamping device for welding steel grating, including a workbench. The upper side of the workbench has multiple sets of placement slots. The upper side of the workbench located on both sides of the multiple sets of placement slots has two movable holes. Movable plates are slidably connected to the inner walls of the workbench located inside the two movable holes.

[0006] By adopting the above technical solution, flat steel is placed into the placement slot on the workbench by workers or a feeding mechanism, which limits the position of the flat steel. The conveying mechanism can transport the crossbar from each set of pressing guide wheels to the top of the flat steel. The pressing guide wheels rotate on the movable plate to facilitate feeding, and the pressing guide wheels, with the cooperation of their guide grooves, play a pressing role, which facilitates welding by welding equipment, reduces the occurrence of shaking of flat steel and crossbar, and enhances the quality of the welded steel grating.

[0007] Optionally, fixed plates are fixedly connected to the lower ends of both sides of the workbench, and a bidirectional lead screw is rotatably installed on one side of the two fixed plates facing each other. The bidirectional lead screw is threaded through the two movable plates.

[0008] By adopting the above technical solution, the worktable can fix the fixed plate, and the fixed plate can provide rotational support for the bidirectional lead screw. Then, when the bidirectional lead screw rotates, it can cause the two movable plates to move in opposite directions.

[0009] Optionally, guide rods are fixedly installed on the inner walls of the two fixed plates located on one side of the bidirectional lead screw, and the guide rods slide through the two movable plates.

[0010] By adopting the above technical solution, the fixed plate can fix the guide rod, while the guide rod can limit and guide the sliding of the movable plate.

[0011] Optionally, a reciprocating motor is mounted on the outer wall of one of the fixed plates, and the output shaft of the reciprocating motor is fixedly connected to the rotating shaft of the bidirectional lead screw.

[0012] By adopting the above technical solution, the fixing plate can fix the reciprocating motor, and the reciprocating motor can drive the bidirectional lead screw to rotate.

[0014] By adopting the above technical solution, multiple pressing guide wheels can be easily rotated with the help of the belt when the pulley rotates.

[0015] Optionally, a bracket is fixedly connected to the lower end of the movable plate located on one side of the pulley, and a stepper motor is installed on one side of the bracket. The output shaft of the stepper motor is fixedly connected to the rotating shaft of one of the pulleys.

[0016] By adopting the above technical solution, the movable plate can fix the bracket, which in turn can fix the stepper motor, and the stepper motor can drive one of the pulleys to rotate.

[0017] Optionally, a controller is fixedly installed on one side of the worktable, and the controller is electrically connected to the stepper motor and the reciprocating motor.

[0018] By adopting the above technical solution, the workbench can fix the controller, and the controller can facilitate the operation of the stepper motor and reciprocating motor by the staff.

[0019] Optionally, the lower end of the workbench is fixedly connected to multiple sets of legs, which are arranged in a rectangular array.

[0020] By adopting the above technical solution, the support legs can provide support for the workbench.

[0021] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0022] The technical solution of this application allows workers or a feeding mechanism to place flat steel into the placement slot on the workbench, which serves to limit the movement of the flat steel.

[0029] Please see Figure 1-4 This utility model provides a technical solution: a pressing device for welding steel grating, including a workbench 1, with multiple sets of placement slots 2 opened on the upper side of the workbench 1, and two movable holes 5 opened on the upper side of the workbench 1 located on both sides of the multiple sets of placement slots 2. Movable plates 3 are slidably connected to the inner walls of the workbench 1 located inside the two movable holes 5. Multiple sets of pressing guide wheels 4 are rotatably installed in the inner walls at the upper ends of the two movable plates 3, and each set of pressing guide wheels 4 is a pair.

[0030] Multiple sets of pulleys 7 are rotatably mounted on the lower end of one of the movable plates 3. Belts 9 are respectively installed on the outer walls of the multiple sets of pulleys 7, and the rotating shafts of the multiple sets of pulleys 7 are fixedly connected to the rotating shafts of the corresponding pressing guide wheels 4. A bracket 6 is fixedly connected to the lower end of the movable plate 3 located on one side of the pulleys 7. A stepper motor 8 is installed on one side of the bracket 6, and the output shaft of the stepper motor 8 is fixedly connected to the rotating shaft of one of the pulleys 7.

[0031] In the technical solution of this utility model, the flat steel is placed into the placement groove 2 on the workbench 1 by the worker or the feeding mechanism, which plays a limiting role in the flat steel. The conveying end of the external equipment conveying mechanism (conveyor belt or conveyor guide wheel) corresponds to the pressing guide wheel 4. When the external equipment conveying mechanism is conveying, the crossbar will pass through the space between each set of pressing guide wheels 4, and then the crossbar can be conveyed from each set of pressing guide wheels 4 to the top of the flat steel. The pressing guide wheel 4 rotates on the movable plate 3 to facilitate feeding, and the pressing guide wheel 4 plays a pressing role with its guide groove. The guide groove of the pressing guide wheel 4 is adapted to the crossbar, and then the guide groove on the pressing guide wheel will play a limiting role in the crossbar. This limiting method is similar to pressing, which facilitates welding equipment welding, reduces the occurrence of shaking of flat steel and crossbar, and enhances the quality of steel grating welded products.

[0032] In addition, when the pulley 7 rotates, it facilitates the rotation of multiple pressure guide wheels 4 with the cooperation of belt 9. The movable plate 3 can fix the bracket 6, and the bracket 6 can fix the stepper motor 8. The stepper motor 8 can drive one of the pulleys 7 to rotate.

[0033] In the technical solution of this utility model, such as Figure 1 and Figure 3 As shown, fixed plates 10 are fixedly connected to the lower ends of both sides of the worktable 1. A bidirectional lead screw 11 is rotatably installed on one side of the two fixed plates 10 facing each other. The bidirectional lead screw 11 is threaded through the two movable plates 3. The worktable 1 can fix the fixed plates 10, and the fixed plates 10 can provide rotational support for the bidirectional lead screw 11. When the bidirectional lead screw 11 rotates, it can cause the two movable plates 3 to move in opposite directions. Guide rods 12 are fixedly installed on the inner walls of the two fixed plates 10 located on one side of the bidirectional lead screw 11. The guide rods 12 slide through the two movable plates 3. The fixed plates 10 can fix the guide rods 12, and the guide rods 12 can limit and guide the sliding of the movable plates 3. A reciprocating motor 13 is installed on the outer wall of one of the fixed plates 10. The output shaft of the reciprocating motor 13 is fixedly connected to the rotating shaft of the bidirectional lead screw 11. The fixed plates 10 can fix the reciprocating motor 13, and the reciprocating motor 13 can drive the bidirectional lead screw 11 to rotate.

[0034] In the technical solution of this utility model, such as Figure 1 and Figure 3 As shown, a controller 14 is fixedly installed on one side of the workbench 1. The controller 14 is electrically connected to the stepper motor 8 and the reciprocating motor 13. The workbench 1 can fix the controller 14, and the setting of the controller 14 can facilitate the operation of the stepper motor 8 and the reciprocating motor 13 by the staff.

[0035] In the technical solution of this utility model, such as Figure 1 and Figure 3 As shown, the lower end of the workbench 1 is fixedly connected to multiple sets of legs 15, which are arranged in a rectangular array to support the workbench 1.

[0036] In use, the flat steel is first placed into the placement slot 2 on the workbench 1 by the worker or the feeding mechanism, which limits the movement of the flat steel. The conveying mechanism can transport the crossbar from each set of pressing guide wheels 4 to the top of the flat steel. The stepper motor 8 can drive a pulley 7 to rotate, and multiple pulleys 7, in conjunction with the belt 9, drive multiple pressing guide wheels 4 to rotate. Then, the pressing guide wheels 4 rotate on the movable plate 3 to facilitate the feeding of the crossbar. The pressing guide wheels 4, in conjunction with their guide slots, play a pressing role, which facilitates welding by the welding equipment, reduces the swaying of the flat steel and crossbar, and enhances the quality of the welded steel grating. After the steel grating is successfully welded, the reciprocating motor 13 can drive the bidirectional lead screw 11 to rotate. The bidirectional lead screw 11, in conjunction with the guide rod 12, facilitates the movement of the two movable plates 3 in opposite directions, which in turn facilitates the removal of the steel grating.
