Description

Technical Field

[0001] The utility model relates to the technical field of punching equipment, and more specifically, to a drilling device for processing square steel pipes. Background Art

[0002] Square steel pipe is abbreviated as square steel pipe, also known as square tube. It is a name for square pipes, that is, steel pipes with equal sides. Generally, the strip steel is unpacked, flattened, curled, and welded to form a round tube, and then the round tube is rolled into a square tube and then cut into the required length. Square tubes are divided into seamless and welded ones. Compared with solid steel such as round steel, square steel pipes have a lighter weight when the bending and torsional strength are the same. It is an economical cross-section steel and is widely used in construction, machinery manufacturing, railway construction and other fields.

[0003] When drilling holes in square steel pipes, operators often use drilling devices to drill the required holes or grooves on the outer surface of the square steel pipe for subsequent use. In actual use, although the existing drilling devices have basic drilling functions, in the existing drilling devices, the drill can generally only drill downwards, and the drilling angle cannot be changed. Therefore, it cannot meet the operator's needs for oblique drilling of square steel, so it needs to be improved. Utility Model Content

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.

[0028] like Figures 1 to 7 As shown, the utility model provides a drilling device for processing square steel pipes, comprising:

[0029] A bed body 1, a punching groove 2 is provided in the middle of the rear side of the upper surface of the bed body 1, and a sliding groove 3 is provided on the upper surface of the bed body 1 and is located on the left side of the punching groove 2;

[0030] Support frames 4, the number of support frames 4 is two, the lower surfaces of the two support frames 4 are fixedly connected to the two sides of the upper surface of the bed body 1, the tops of the left and right sides of the inner surface of the support frames 4 are fixedly connected with the central axis 30, and the outer surface of the central axis 30 is movably sleeved with a movable plate 5 located just above the punching slot 2;

[0031] An adjustment mechanism, the adjustment mechanism is arranged below the sliding slot 3;

[0032] Among them, the adjustment mechanism includes a No. 1 motor 6, which is fixedly installed on the right side of the lower surface of the bed body 1. The other end of the output shaft of the No. 1 motor 6 is fixedly sleeved with a rotating shaft 7, and the outer surface of the rotating shaft 7 is fixedly sleeved with a rotating wheel 8. The outer surface of the rotating wheel 8 is fixedly connected to a connecting column 9 located below the sliding groove 3. The outer surface of the connecting column 9 is hinged with a connecting rod 10. The top end of the connecting rod 10 passes through the sliding groove 3 and extends to the top of the sliding groove 3 and is hinged to the right side of the lower surface of the movable plate 5. The rotation of the rotating wheel 8 causes the connecting column 9 to drive the connecting rod 10 to rotate, so that the movable plate 5 rotates as a whole.

[0033] When motor No. 1 is running, the rotating shaft 7 will drive the rotating wheel 8 and the connecting column 9 to start rotating. The rotation of the connecting column 9 will drive the connecting rod 10 so that the bottom end of the connecting rod 10 starts to rotate with the connecting column 9 as the axis. At this time, the other end of the connecting rod 10 will drive the movable plate 5, so that the movable plate 5 as a whole starts to rotate with the central axis 30 as the axis, thereby realizing the change of the drilling angle.

[0034] A pneumatic cylinder 11 is fixedly mounted on the upper surface of the movable plate 5 , and a bottom end of the pneumatic cylinder 11 penetrates the movable plate 5 and extends to the bottom of the movable plate 5 and is fixedly connected to a mounting block 12 .

[0035] When the pneumatic cylinder 11 is in operation, the mounting block 12 will start to move downward.

[0036] A second motor 13 is fixedly mounted on the inner surface of the mounting block 12 , a connecting shaft 14 is fixedly sleeved on the other end of the output shaft of the second motor 13 , and a drill bit 15 is fixedly connected to the lower end of the connecting shaft 14 .

[0037] When the second motor 13 is running, the connecting shaft 14 will drive the drill bit 15 to start rotating.

[0038] Among them, a limiting plate 28 is fixedly connected to the middle part of the upper surface of the bed body 1, and a No. 3 motor 16 is fixedly installed on the left side of the lower surface of the bed body 1. The other end of the output shaft of the No. 3 motor 16 is fixedly sleeved with a round shaft 17. The top end of the outer surface of the round shaft 17 passes through the bed body 1 and extends to the top of the bed body 1 and is fixedly sleeved with a first driving wheel 21. The lower side of the outer surface of the round shaft 17 is fixedly sleeved with a driving gear 18 located on the lower side of the bed body 1.

[0039] When the third motor 16 is running, the circular shaft 17 will drive the driving gear 18 and the first driving wheel 21 to start rotating.

[0040] The outer surface of the driving gear 18 is meshed with the driven gear 19, and the inner surface of the driven gear 19 is fixedly sleeved with the driven shaft 20. The top of the outer surface of the driven shaft 20 passes through the bed 1 and extends to the upper side of the bed 1 and is fixedly sleeved with a transmission wheel 29.

[0041] When the driving gear 18 starts to rotate, the driven gear 19 starts to rotate under the meshing transmission of the driving gear 18 and drives the transmission wheel 29 to rotate together.

[0042] Among them, the upper side of the outer surface of the first driving wheel 21 and the upper side of the outer surface of the transmission wheel 29 are both hinged with a hinged plate 22, the other end of the hinged plate 22 is hinged with a second driving wheel 23, the inner surface of the second driving wheel 23 is movably sleeved with a mounting shaft 31, and the lower surface of the mounting shaft 31 is fixedly connected to the upper surface of the bed body 1.

[0043] When the first driving wheel 21 and the transmission wheel 29 start to rotate, the two hinged plates 22 will start to rotate driven by the first driving wheel 21 and the transmission wheel 29 respectively, and the rotation of the hinged plates 22 will also cause the two second driving wheels 23 to start to rotate around the mounting shaft 31.

[0044] Among them, the inner surface of the middle part of the hinged plate 22 is movably sleeved with a push rod 24, and the outer surface of the push rod 24 is respectively fixedly sleeved with a fixed plate 25 and a push plate 26 located on the outer and inner sides of the hinged plate 22. The outer surface of the push rod 24 is movably sleeved with a spring 27, and the outer end of the spring 27 is fixedly connected to the inner surface of the fixed plate 25, and the other end of the spring 27 is fixedly connected to the outer surface of the hinged plate 22.

[0045] When the first driving wheel 21, the second driving wheel 23 and the transmission wheel 29 start to rotate, the push rod 24 will start to rotate along with the hinged plate 22, and the two push plates 26 will fit against the outer surface of the square steel pipe and clamp the square steel pipe during the rotation. At this time, since the hinged plate 22 is still rotating, the hinged plate 22 will move along the outer surface of the push plate 26 toward the outer surface of the steel pipe, while also driving the two push rods 24 as a whole and the square steel pipe to move toward the direction of the drill bit 15.

[0046] The working principle and use process of this utility model:

[0047] First, the operator places the steel pipe between the two limit plates 28 and the two push plates 26, and then starts the No. 3 motor 16. The operation of the No. 3 motor 16 will cause the circular shaft 17 to drive the driving gear 18 and the first driving wheel 21 to start rotating, and the driven gear 19 will start rotating under the meshing transmission of the driving gear 18 and drive the transmission wheel 29 to rotate together. Due to the rotation of the first driving wheel 21 and the transmission wheel 29, the two hinged plates 22 will start rotating under the drive of the first driving wheel 21 and the transmission wheel 29 respectively, and the other ends of the two hinged plates 22 will drive the two second driving wheels 23 to start rotating. The push rods 24 rotate in opposite directions with the two mounting shafts 31 as the axis. At the same time, the push rod 24 as a whole will rotate along with the hinge plate 22. The two push plates 26 will fit against the outer surface of the square steel pipe in the process. At this time, since the hinge plate 22 is still rotating, the hinge plate 22 will move along the outer surface of the push rod 24 toward the outer surface of the steel pipe. This causes the two springs 27 to be pulled due to the movement of the hinge plate 22, so that the two push rods 24 as a whole clamp the square steel pipe. At the same time, the rotation of the two hinge plates 22 also causes the two push rods 24 as a whole to push the square steel pipe toward the direction of the drill bit 15.

[0048] When the steel pipe moves to the bottom of the drill bit 15, the operator starts the No. 1 motor 6. The operation of the No. 1 motor 6 will cause the rotating shaft 7 to drive the rotating wheel 8 and the connecting column 9 to start rotating. The rotation of the connecting column 9 will drive the connecting rod 10, so that the bottom end of the connecting rod 10 starts to rotate with the connecting column 9 as the axis. At this time, the other end of the connecting rod 10 will drive the movable plate 5, so that the movable plate 5 as a whole starts to rotate with the central axis 30 as the axis. When the drill bit 15 rotates to a predetermined drilling angle, the operator starts the pneumatic cylinder 11 and the No. 2 motor 13. The operation of the pneumatic cylinder 11 will cause the mounting block 12 to move toward the outer surface of the square steel pipe as a whole, and the operation of the No. 2 motor 13 will cause the connecting shaft 14 to drive the drill bit 15 to start rotating. Finally, the drill bit 15 will complete the oblique drilling of the square steel pipe under the joint action of the mounting block 12 and the No. 2 motor 13.
