Description

Technical Field

[0001] The present invention relates to the technical field of flange processing, and more specifically, to a high-efficiency drilling device for flange processing. Background Art

[0002] Flange is an important mechanical part, mainly used for connecting shafts, pipes, and equipment. It is tightly connected to another flange through bolts, nuts and other fasteners to achieve a sealing effect. Flanges are widely used in petroleum, chemical, machinery, electric power, metallurgy, shipbuilding, construction and other industries.

[0003] Existing flanges generally have a central circular hole and a circle of mounting holes around it, and have an annular flange. The mounting holes around it are processed one by one by the drilling unit during processing. However, when drilling holes in existing flanges, manual loading and unloading are required, and each loading and unloading takes a long time, which affects the processing efficiency. In addition, relying on manual operation increases labor costs. Manual operation may also cause inaccurate loading or untimely unloading due to factors such as fatigue and distraction, affecting the overall processing efficiency. Traditional drilling devices often have time intervals in loading and unloading, and may need to be shut down for operation, resulting in the inability of the equipment to operate continuously and efficiently. This production discontinuity directly affects the overall production efficiency. Some drilling devices mostly perform quality inspections after drilling is completed. This post-detection method cannot promptly detect and solve problems in the drilling process, resulting in an increase in the defective rate, while increasing the cost and time of subsequent processing. Summary of the invention

[0004] The present invention aims to overcome the defects of the prior art and provide a high-efficiency drilling device for flange processing.

[0005] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a drilling device for flange processing, comprising a substrate, a material loading and rotating unit, a fixed limiting unit, a material unloading unit, a material moving unit and a drilling unit; the material loading and rotating unit comprises a circular rotating annular portion installed on the substrate and capable of rotating on the substrate, and a first rotating driving unit for driving the rotating annular portion to rotate, the rotating annular portion having a plurality of bearing positions for bearing flanges; the fixed limiting unit comprises a fixed seat fixedly connected to the substrate, two connecting rods fixedly connected to the fixed seat, a U-shaped frame connected to the two connecting rods, a U-shaped seat fixedly connected to the U-shaped frame, and a fixed annular portion fixedly connected to the U-shaped seat, the fixed annular portion is surrounded by the rotating annular portion, and the fixed annular portion abuts against the upper surface of the substrate; the material moving unit can be used to move the flange, and the drilling unit is used to drill holes in the flange to be processed.

[0006] Furthermore, the drilling unit includes a frame, a lifting drive unit, a rotating drive unit, a drill bit installation unit, a coolant supply unit and a drill bit.

[0007] Thus, under the rotation and cutting action of the drill, the flange material is gradually removed and a mounting through hole is formed.

[0008] Furthermore, each bearing position has two strip-shaped limit plates, and a strip pressure plate is hingedly connected to the strip limit plates through an elastic reset hinge component, and both ends of the strip pressure plate have arc chamfers; the base plate is connected to a first mounting plate through a plurality of L-shaped connecting plates, and a first electric lifting rod is installed on the first mounting plate, and the first electric lifting rod drives a second rotation driving unit, and the second rotation driving unit drives a first lifting seat, and the first lifting seat can pass through the center hole of the fixed annular portion, and the U-shaped seat is connected to a second mounting plate through a plurality of radial rods, and a first electric lifting rod is installed on the second mounting plate.

[0016] The avoidance groove ensures that the teeth will not collide with the receiving seat when the rotating annular portion rotates.

[0017] Furthermore, it also includes a detection unit, which includes a mounting frame installed on the receiving seat, a plurality of fourth electric lifting rods installed on the mounting frame, and a second lifting plate driven by the fourth electric lifting rods, and the second lifting plate has a plurality of second positioning columns; the mounting frame includes two L-shaped frames and an arc-shaped connecting plate connecting the two L-shaped frames, the first positioning columns are three, and the second positioning columns are five.

[0048] Working principle: The drilling device of the present application, as shown in the figure, the two strip pressure plates of the bearing position can clamp the flange under the action of the elastic reset hinge component. When there is no external force, the flange will not move, but under the action of the material moving unit, the flange can be moved. The multiple bearing positions at the rotating annular portion can be aligned with the channel of the U-shaped seat in turn, so that the flange can be transferred to the first lifting seat in turn, so that the first lifting seat can rise to cooperate with the rotating plate to clamp the flange, so that the drill of the drilling unit can descend to the corresponding position to process the mounting hole of the flange, and after one mounting hole is processed, the second rotating drive unit can rotate the flange by a certain angle (45 degrees in the figure) to drill the next mounting hole. When the second rotating drive unit rotates, the second lifting seat is in a higher position, so that the arc-shaped abutment block does not abut the rotating plate, so that the rotating plate can rotate smoothly. When drilling, the second lifting seat is in a lower position, so that the arc-shaped abutment block abuts the rotating plate, so that the position of the rotating plate is more stable.

[0049] The multiple first positioning columns of the material moving unit can detect the positions of several mounting holes on the one hand, and can move to realize the movement of the flange on the other hand. The multiple second positioning columns of the detection unit can also detect and locate the mounting holes of the flange, so that the multiple first positioning columns and the multiple second positioning columns can detect and locate all the mounting holes of the flange. When the third electric lifting rod and the fourth electric lifting rod are lifted and lowered normally, it means that there is no problem with the position and aperture of the mounting holes of the flange. When the lifting operation of the third electric lifting rod and the fourth electric lifting rod is blocked according to the program, it means that there is a deviation in the position of the flange, or the position of the mounting holes of the flange is deviated, and alarm maintenance is required.

[0050] The specific process is shown in the figure. First, Figure 1 As shown, the material transfer unit faces a flange to be processed (referred to as flange B, the processed flange upstream thereof is referred to as flange A, and the flange to be processed downstream thereof is referred to as flange C); then as Figure 4 As shown, the material transfer unit pushes flange B to the first lifting seat; then Figure 5 As shown, the first lifting seat rises and cooperates with the rotating plate to clamp the flange; then Figure 6 As shown, the rotating ring part rotates counterclockwise by one bearing position so that the flange A faces the material shifting unit; then as shown in FIG. Figure 7 As shown, while the drilling unit is drilling a hole in flange B, the first positioning column of the material moving unit is matched with the mounting through hole of flange A; then Figure 8 As shown, the material transfer unit transfers the flange to the bottom of the detection unit, and the detection unit detects the mounting through hole of the flange; then as shown Fig. 9 As shown in FIG. 1 , after the detection is completed, the material transfer unit continues to pull the flange A backward, so that the flange A falls into the material discharge channel; then as shown in FIG. Fig.10 As shown in FIG. 1 , the second push plate pushes flange A downstream, thereby leaving space for the subsequent flange B to fall; then as shown in FIG. Fig.11 As shown, the rotating ring portion rotates clockwise for one bearing position; then Fig.12 As shown in FIG. 1 , at this time, the flange B is processed and the material transfer unit is ready to pull out the flange B; then Fig.13 As shown in FIG. 1 , the material transfer unit pulls out flange B, and at this time, a new flange to be processed is loaded at the position where flange A was originally located; then as shown in FIG. Fig.14 As shown, the rotating ring part continues to rotate, preparing to align the flange C with the material transfer unit; then Fig.15 As shown, flange C is aligned with the material transfer unit, and the mobile unit is ready to transfer flange C to the first lifting seat, so as to process flange C. In the subsequent processing of flange C, the rotating ring part must also rotate counterclockwise, and the material transfer unit must also transfer flange B to the bottom of the detection unit for detection, and after the detection is completed, flange B is transferred to the unloading channel. And subsequently, at the loading position, a new flange to be processed is loaded into the empty space that originally carried flange B. By repeating this process, multiple flanges can be processed uninterruptedly.
