Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a bolt hole cleaning device for steel structure connecting plates and its construction method. Background Technology

[0002] With the widespread use of high-strength bolts in the joint connections of steel structure engineering projects, CNC drilling machines are used for stacking drilling of bolt holes in steel structure connection plates to improve the machining accuracy and efficiency. However, after drilling, burrs and iron filings remain at the corners of the bolt holes, affecting the surface finish of the hole walls. Current methods for cleaning burrs and iron filings involve using a grinding wheel angle grinder, which is ineffective and inefficient. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, a bolt hole cleaning device and its construction method for steel structure connecting plates are provided to solve the problem of low burr cleaning efficiency of existing steel structure connecting plates.

[0004] To achieve the above objectives, a bolt hole cleaning device for steel structure connecting plates is provided, comprising:

[0005] A mobile frame having a vertically arranged operating opening, and two first transmission screws mounted on the mobile frame, the two first transmission screws being respectively arranged on opposite sides of the operating opening;

[0006] The movable seat has threaded holes at both ends, and the two first transmission screws are respectively screwed into the threaded holes of the two movable seats. The mobile frame is equipped with a first motor for driving the first transmission screws. The support has two sliding grooves arranged in the same direction, and the sliding grooves are set at an angle to the first transmission screws.

[0007] A support having a slider that slides in a groove and a rack in another groove along the length of the groove; the support is rotatably equipped with a gear meshing with the rack and a second motor for driving the gear.

[0008] A footing is mounted on the support in a height-adjustable manner, and the footing is equipped with an electric chamfering drill bit;

[0009] The controller is connected to the first motor, the second motor, the support platform, and the electric chamfering drill bit. The controller adjusts the position of the electric chamfering drill bit through the first motor and the second motor so that the electric chamfering drill bit is aligned with the bolt hole of the steel structure connecting plate below the operating opening. Then, by lowering the support platform, the electric chamfering drill bit passes through the operating opening and grinds and cleans the bolt hole.

[0010] Furthermore, it also includes two laser emitters. The operating opening is rectangular. One laser emitter is adjustablely mounted on the mobile frame along the length of the operating opening, and the other laser emitter is adjustablely mounted on the mobile frame along the width of the operating opening. The intersection of the laser beams of the two laser emitters coincides with the center of a bolt hole in the vertical direction.

[0011] Furthermore, the mobile frame includes two crossbeams and two longitudinal beams. The crossbeams are connected between the ends of the longitudinal beams, and the two crossbeams and the two longitudinal beams enclose the operating opening. The longitudinal beams are equipped with electric rollers, and the electric rollers are connected to the controller.

[0012] Furthermore, a support plate is vertically mounted on the support, and a platform is connected to the top of the support plate. A second transmission screw is rotatably mounted between the platform and the support. The platform has a threaded hole, and the second transmission screw is screwed into the threaded hole of the platform. A vertically arranged guide groove is formed on the support plate, and a guide block is formed on the platform. The guide block slides in the guide groove. A third motor for driving the second transmission screw is mounted on the platform.

[0013] Furthermore, the support platform has a vertically oriented shaft hole, and the electric chamfering drill bit is coaxially connected to a drill rod. The drill rod is rotatably installed in the shaft hole, and a fourth motor for driving the drill rod is installed on the support platform.

[0014] This invention provides a construction method for a bolt hole cleaning device for steel structure connecting plates, comprising the following steps:

[0015] Lay the steel structure connecting plate on the workbench;

[0016] Move the mobile frame above the steel structure connecting plate so that the operating opening of the mobile frame is aligned with the bolt holes of the steel structure connecting plate.

[0017] The controller adjusts the position of the electric chamfering drill bit through the first motor and the second motor so that the electric chamfering drill bit is aligned with the bolt hole of the steel structure connecting plate below the operating opening;

[0018] The controller lowers the platform so that the electric chamfering drill bit passes through the operating hole and aligns with the bolt hole;

[0019] The controller activates the electric chamfering drill bit to grind and clean the bolt holes.

[0020] The beneficial effects of this invention are as follows: the bolt hole cleaning device for steel structure connecting plates of this invention uses a first motor to drive a first transmission screw to move a movable seat along the axial direction of the first transmission screw, and a second motor to drive a gear to move a support along the length of the sliding groove of the movable seat. This allows the electric chamfering drill bit to be aligned with the bolt holes of the steel structure connecting plate to be cleaned. Finally, the lowering of the support platform grinds and cleans burrs, iron filings, etc., in the bolt holes, achieving efficient grinding and cleaning of the bolt holes of the steel structure connecting plates, thus improving the construction efficiency and quality of steel structures.

[0054] After grinding and cleaning the bolt holes at the reference points, the controller adjusts the position of the electric chamfering drill bit 41 by using the first motor 15 and the second motor 33 according to the set modular step distance (moving along the length direction of the crossbeam and longitudinal beam) to align with each bolt hole in turn and raise and lower it to grind and clean the bolt holes, thereby chamfering the bolt holes of the steel structure connecting plate.

[0055] After grinding and cleaning the bolt holes on the front side of the steel structure connecting plate, flip the steel structure connecting plate over and repeat the above steps to grind and clean the bolt holes on the back side of the steel structure connecting plate.
