Description

Technical Field

[0001] The invention relates to the technical field of steel pipe drilling, in particular to a multi-station steel pipe drilling machine. Background Art

[0002] A drilling machine is a general term for machinery and equipment that uses a tool that is harder and sharper than the target object to leave a cylindrical hole or hole on the target object through rotary cutting or rotary extrusion. Among them, steel pipe drilling is a common processing method. It can form one or more holes on the surface of the steel pipe to facilitate the connection of other structural parts or the installation of other components.

[0003] For example, CN116532686A involves a seamless steel pipe drilling machine, a base, a clamp, a support column, a cooling device, a lubricating device, a motor, a control box, a rocker, and a drill bit. Through the setting of the lubricating device, when the drill bit rotates, it drives a linkage rod fixed to the drill bit. During the rotation of the linkage rod, it will press against the sphere, and the sphere will enter the oil pipe, and the lubricating oil will flow out through the third slot and flow to the sponge strip. The sponge strip that has absorbed the lubricating oil will apply the lubricating oil to the drill bit, and the lubricating oil will flow along the cone of the drill bit to the drill bit at the bottom of the drill bit to lubricate the drill bit. When the linkage rod leaves, the sphere will re-seal the oil pipe, solving the problem of excessive wear of the drill bit due to lack of lubrication of the drill bit. However, when there is more than one hole to be processed on the steel pipe and the drilling angle needs to be changed, the operator is required to disassemble and fix the steel pipe many times.

[0037] The fixed body 2 includes a second slide plate 211 and an end plate 221 rotatably connected to the second slide plate 211. The second slide plate 211 is located in the lifting frame 114. The second slide plate 211 is connected to the lifting frame 114 by sliding up and down. The bottom of the second slide plate 211 is connected to the bottom of the lifting frame 114 through a second hydraulic body. The end of the end plate 221 away from the lifting frame 114 is provided with a fixing structure for fixing the steel pipe. The steel pipe is introduced into the processing table 11 along the first guide wheel 122. The fixing structure penetrates into the steel pipe to fix the steel pipe. The second hydraulic body drives the second slide plate 211 to move up along the lifting frame 114, so that the steel pipe is close to the bottom of the drilling rig 135. The sliding lifting processing structure at the top of the two ends of the processing table 11 adjusts the drilling rig. 135, the second hydraulic body drives the second slide plate 211 downward, so that the bottom of the steel pipe contacts and is supported by the first guide wheel 122, and the support plate 121 is pressed by the steel pipe, overcomes the spring force and moves downward along the middle groove 112 to drive the locking structure to fix the lifting processing structure, so that the lifting processing structure cannot move laterally, and then the first hydraulic body drives the first slide plate 131 to move downward along the lifting frame 114, driving the lifting processing structure to move downward, so that the bottom of the drilling rig 135 contacts the steel pipe for drilling.

The rotating plate 123 rotatably connected to the support plate 121 slides and drives the side plate 124 to rotate, so that the second guide wheel 125 contacts the surface of the steel pipe. Through the multi-point contact of the first guide wheel 122 and the second guide wheel 125, the supporting and fixing effect of the steel pipe can be ensured. The cone structure can contact the steel pipe under the premise of ensuring that the second guide wheel 125 can rotate;

[0039] After the steel pipe is placed in the processing table 11, the inside of the steel pipe needs to be fixed. The fixing structure includes a central axis 222 coaxially connected to the end plate 221, and a plurality of inner contact bodies 223 are symmetrically arranged on the central axis 222. The inner contact body 223 is provided with a contact sheet at one end away from the central axis 222. The central axis 222 contacts the inner wall of the steel pipe through the inner contact body 223 and the contact sheet. Considering that the steel pipes to be drilled have different diameters, a plurality of shaft protrusions 224 are symmetrically connected to the central axis 222. The inner wall of the inner contact body 223 is slidably connected to the outer wall of the shaft protrusion 224. A hollow sleeve 225 is rotatably connected in the shaft protrusion 224. The middle part of the inner contact body 223 close to one end of the central axis 222 is located in the hollow sleeve 225.

The second motor 227 drives the drive shaft 228, and then drives the hollow sleeve 225 to rotate in the shaft protrusion 224, so that the hollow sleeve 225 drives the inner contact body 223 threadedly connected thereto to slide outward along the outer wall of the shaft protrusion 224 until the contact piece contacts the inner wall of the steel pipe, and the contact surface between the contact piece and the steel pipe is an arc surface, thereby ensuring the fixing effect on the steel pipe;

[0040] After the steel pipe is fixed, the second slide plate 211 is driven by the second hydraulic body to move up along the lifting frame 114, so that the fixed structure drives the steel pipe to move up and approach the bottom of the drilling machine 135.

After the position adjustment of the drilling machine 135 is completed, the second hydraulic body The second slide plate 211 is driven to move downward, and then the fixed structure and the steel pipe are driven to move downward, until the bottom of the steel pipe contacts the support plate 121, and the support plate 121 is driven to move downward. In the process that the support plate 121 moves downward and drives the side plate 124 to rotate so that the second guide wheel 125 contacts the steel pipe, the support plate 121 drives the rack 127 to move in the end groove 115 through the external connecting frame 126, until the rack 127 is stuck in the first tooth groove 137, so that the vertical plate 132 is fixed, that is, the drilling rig 135 cannot move horizontally. At this time, the first hydraulic body drives the first slide plate 131 and then drives the drilling rig 135 downward to drill holes in the steel pipe;

[0042] After completing the drilling of the steel pipe, it is necessary to rotate the steel pipe for drilling again. The second slide plate 211 is provided with a first motor 212, and the first motor 212 is connected to the driving gear 213. The outer wall of the end plate 221 is correspondingly provided with a second tooth groove 229, and the second tooth groove 229 is meshed with the driving gear 213. After the first drilling of the steel pipe is completed, the second hydraulic body drives the second slide plate 211 and then drives the steel pipe to move upward and close to the bottom of the drilling rig 135. The first motor 212 drives the end plate 221 to rotate through the driving gear 213 and then drives the steel pipe to rotate. After adjusting the position of the drilling rig 135 again, repeat the above process to drill again.
