Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, and in particular to a drilling machine for anti-displacement steel structure metal components. Background Technology

[0002] Steel structure refers to a structural form that can bear and transmit loads, made of steel plates and hot-rolled, cold-bent or welded profiles connected by connectors.

[0003] Steel structures are made by connecting profiles. Before use, the profiles need to be cut to the required length and holes need to be drilled in the profile components cut to the specified size for installation and connection. However, drilling using traditional methods is slow to align the position and is also prone to displacement, resulting in inaccurate positioning. Therefore, this application discloses a drilling machine for anti-displacement steel structure metal components. Utility Model Content

[0004] The purpose of this invention is to address existing problems by providing a drilling machine for anti-displacement steel structure metal components.

[0005] This utility model is achieved through the following technical solution: a drilling machine for anti-deviation steel structure metal components, including a frame, several free rollers are spaced apart on the frame, a pad is symmetrically arranged in the middle of the frame, a column of a lifting mechanism is connected below the pad, the lifting mechanism is installed inside the frame, a drill bit is arranged above the pad, the drill bit is installed on a tool holder, the tool holder is connected to the output shaft of a motor, the motor is installed on a base plate, the base plate is suspended in a top frame through a sliding mechanism, and the top frame is connected above the frame.

[0006] As a further improvement to the above solution, the lifting mechanism includes columns that are symmetrically and spaced apart from the frame. The working rod end of a hydraulic cylinder is connected to the lower center of the frame. The hydraulic cylinder is vertically connected to the lower part of the frame. Support cylinders are symmetrically arranged on both sides of the hydraulic cylinder, and support rods are inserted into the support cylinders. The upper ends of the support rods are connected to the lower part of the frame. The hydraulic cylinder lifts and supports the pad, and at the same time, the support rods on both sides of the hydraulic cylinder slide up and down in the support cylinders to ensure the stability and levelness of the pad during the lifting displacement, and to prevent the profile components placed on the pad from moving during drilling.

[0007] As a further improvement to the above solution, the sliding mechanism includes a top plate, which is installed on the top of the top frame. A second hydraulic cylinder is connected to one diagonal of the top plate, and the working rod of the second hydraulic cylinder is connected to the base plate. A guide rod is provided through the other diagonal of the top plate, and the lower end of the guide rod is connected to the base plate. The second hydraulic cylinder lowers the hoisting motor and raises the motor, and the guide rod ensures the balance and stability of the motor's lifting and lowering.

[0008] Compared with the prior art, this utility model has the following advantages: it has a compact structure, reasonable design, and novel and unique concept. The profile component is displaced by free rollers, and then the pad is lifted by the lifting mechanism. The pad supports the profile component, which facilitates accurate positioning of the profile component. Then, the hydraulic cylinder pulls the motor, and the lowering and raising motors are used to advance and retract the blade. The pad lifts the profile component and removes it from the rollers, which prevents the profile component from shifting and ensures the accuracy of the drilling position. Attached Figure Description

[0011] Figure 3 This is a schematic diagram of the sliding mechanism. Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings.

[0013] like Figures 1 to 3 As shown, a drilling machine for anti-deviation steel structure metal components includes a frame 1, on which several free rollers 2 are spaced apart, and a pad 3 is symmetrically arranged in the middle of the frame 1. The column 41 of the lifting mechanism 4 is connected below the pad 3. The lifting mechanism 4 is installed inside the frame 1. A drill bit 10 is arranged above the pad 3 and is mounted on a tool holder 9. The tool holder 9 is connected to the output shaft of a motor 8. The motor 8 is mounted on a base plate 7. The base plate 7 is suspended in a top frame 5 by a sliding mechanism 6. The top frame 5 is connected above the frame 1.

[0014] As a further improvement to the above solution, the lifting mechanism 4 includes a column 41, which is symmetrically and spaced apart from the frame 42. The working rod end of the hydraulic cylinder 43 is connected to the lower middle of the frame 42. The hydraulic cylinder 43 is vertically connected to the lower part of the frame 1. Support cylinders 44 are symmetrically arranged on both sides of the hydraulic cylinder 43. Support rods 45 are inserted into the support cylinders 44. The upper end of the support rods 45 is connected to the lower part of the frame 42. The hydraulic cylinder 43 lifts and supports the pad 3. At the same time, the support rods 45 on both sides of the hydraulic cylinder 43 slide up and down in the support cylinders 44 to ensure the stability and levelness of the pad 3 during the lifting displacement, and to prevent the profile components placed on the pad 3 from moving during drilling.

[0015] As a further improvement to the above solution, the sliding mechanism 6 includes a top plate, which is installed on the top of the top frame 5. A second hydraulic cylinder 62 is connected to one diagonal of the top plate, and the working rod of the second hydraulic cylinder 62 is connected to the base plate 7. A guide rod 61 is provided through the other diagonal of the top plate, and the lower end of the guide rod 61 is connected to the base plate 7. The second hydraulic cylinder 62 lowers and lifts the hoisted motor 8, and the guide rod 61 ensures the balance and stability of the lifting and lowering of the motor 8.

[0016] As a further improvement to the above solution, the pad 3 is arranged on both sides of the intermediate roller so that the pad 3 can move up and down without obstruction.

[0017] The working principle of a drilling machine for anti-deviation steel structure metal components: the profile component is displaced by the free roller 2, and then the pad 3 is lifted by the lifting mechanism 4. The profile component is supported by the pad 3 to facilitate accurate positioning of the profile component. Then, the motor 8 is hoisted by the hydraulic cylinder 2 62. The cutting tool is advanced and retracted by lowering and raising the motor 8, and the profile component is raised by the pad 3.

[0018] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
