It will be understood that when an element is referred to as being "fixed" or "disposed" on another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only and are not meant to be the only embodiment.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1-2, a clamp for multi-angle drilling of steel pipes comprises a clamp body 1, a pressing piece 2 and a dial 3, wherein an arc groove 11 is formed in the upper end of the clamp body 1, the pressing piece 2 comprises a mounting frame 21, a pressing block 22 and an oil cylinder 23, the open end of the mounting frame 21 is connected with the groove edge of the arc groove 11 through bolts, the oil cylinder 23 is arranged on one side, deviating from the arc groove 11, of the mounting frame 21, the output end of the oil cylinder is connected with the pressing block 22, the pressing block 22 is driven to be close to or far away from the arc groove 11, the dial 3 is in a semicircular ring shape, and the dial 3 is arranged on the mounting frame 21 through bolts and is matched with the arc groove 11 to form a circular ring shape. Specifically, during the use, operating personnel inserts two sets of anchor clamps body 1 respectively with the steel pipe both ends in, specifically lay on arc wall 11, then press from both sides tight steel pipe of clamp 2 cooperation arc wall 11, can align and bore. The compressing piece 2 comprises a mounting frame 21, a compressing block 22 and an oil cylinder 23, the oil cylinder 23 is used for driving the compressing block 22 to move up and down, so that when multi-angle drilling is carried out on steel pipes of different types, the steel pipes are replaced or selected conveniently, the steel pipes are clamped or loosened in a mode of manually screwing tiger pliers back and forth, the labor intensity of operators is greatly reduced, and the operation is more convenient. It can be known that when drilling, the steel pipe is placed on the workbench surface of the drilling machine through the clamp, and the drill rod is vertically pressed down, so that the peripheral wall of the steel pipe can be drilled. In order to drill holes on the peripheral wall of the steel pipe at multiple angles, the utility model integrates the dial 3 on the clamp, the dial 3 designed by the utility model is semi-circular, the inner diameter of the dial 3 is far larger than the outer diameter of the steel pipe, and a gap exists between the dial 3 and the peripheral surface of the steel pipe, so that the normal rotation of the steel pipe is not influenced. When the steel pipe needs to be rotated, the oil cylinder 23 drives the compaction block 22 to move upwards, an operator can rotate the steel pipe, in order to confirm the rotation angle, the operator can mark the section of the steel pipe when carrying out initial drilling, namely, a color pen is used for marking, the initial position of the steel pipe for drilling is confirmed, then the steel pipe is rotated, the operator controls the dial 3, the rotation angle of the marking position of the section of the steel pipe is confirmed, the position of the subsequent drilling can be accurately measured, the angle error is avoided when multi-angle drilling is carried out, the machining precision is reduced, and the machining yield is effectively improved.

As shown in fig. 1, a threaded seat 31 is further disposed on the connection side of the dial 3 and the mounting frame 21, and the positioning screw 32 movably penetrates through the threaded seat 31. Specifically, when the peripheral wall of the steel pipe is drilled at multiple angles, an operator is required to rotate the section of the steel pipe just right when rotating the steel pipe, and a gap exists between the marking point of the section of the steel pipe and the dial 3, so that the observation is not easy, and therefore, whether the end of the positioning screw 32 is overlapped with the marking point is confirmed, whether the rotation position of the steel pipe is in place is confirmed, and the rotation angle precision of the steel pipe is ensured. In this embodiment, the number of the screw seats 31 is three, and the central angle between two adjacent screw seats 31 is 60 degrees.

As shown in fig. 1, a sliding groove 211 is formed in the inner side wall of the mounting frame 21, the pressing block 22 is in an inverted U shape, and the left side and the right side of the pressing block 22 are movably clamped in the sliding groove 211. Specifically, when the oil cylinder 23 drives the compression block 22 to move up and down, the sliding groove 211 limits the displacement track of the compression block 22, prevents the compression block 22 from deviating, ensures that the compression block 22 can only vertically approach or depart from the arc-shaped groove 11, and is matched with the arc-shaped groove 11 to clamp the steel pipe to be processed.

As shown in fig. 1-2, a supporting portion 12 is disposed at the lower end of the clamp body 1, and a positioning hole is formed in the supporting portion 12. Specifically, the support part 12 is arranged on the workbench surface of the drilling machine, and is matched with the positioning stud to be fixed below the drill rod for operation, so that the assembly and disassembly are convenient.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model.
