The invention is suitable for the technical field of drilling tools, and provides a low-permeability coal seam layered reaming drilling tool. The mounting pipe is rotationally mounted on the supporting pipe, and a mounting seat is fixedly mounted at the bottom of the mounting pipe; the first drill bit and the second drill bits are arranged on the mounting seat, and the first drill bit and the second drill bits are used for drilling a low-permeability coal seam; the expanding and adjusting mechanism is assembled on the mounting seat and the plurality of second drill bits and is used for expanding and adjusting the transverse use of the second drill bits; the expanding adjustment mechanism comprises a plurality of installation rods installed on the installation base in a sliding mode, and the multiple installation rods are connected with the multiple second drill bits correspondingly. According to the layered reaming drilling tool for the low-permeability coal seam, drilling operation can be conducted on the low-permeability coal seam, the drilling requirements of different layer depths and different diameters of the low-permeability coal seam can be met, layered reaming operation is achieved, and the actual drilling requirements of the low-permeability coal seam are better met.

This invention belongs to the field of metal processing technology and discloses a drilling device for speed reducer production. Addressing the problems raised in the background art, the following solution is proposed: a processing base, a limit bracket fixed to one side of the center of the processing base by bolts, and a mounting top plate slidably inserted into the center of the limit bracket. A hydraulic telescopic rod is connected to the bottom end of the mounting top plate by screws, and a limit cap is fixed to the outer wall of the top of the limit bracket. A reverse drilling rod, a drilling screw, and a tapping tap are rotatably mounted at equal intervals on the top of the mounting top plate. When drilling the housing of a speed reducer motor, this invention utilizes continuously sprayed coolant to reduce frictional heat during drilling. The cooled waste liquid is centrifugally accelerated by the rotation of the stirring blades to settle metal scraps. The supernatant is discharged, filtered, and then extracted again for reuse. This effectively reduces coolant waste and improves resource utilization.

The utility model relates to the technical field of industrial pump machining, in particular to punching fixing equipment for industrial pump machining, which comprises a bottom plate and an inclined plate for fixing an industrial pump, the inclined plate is rotatably connected with the bottom plate, and an angle adjusting mechanism for adjusting the inclination angle of the inclined plate is arranged between the bottom plate and the inclined plate. A supporting assembly used for assisting in fixing the industrial pump is arranged on the side, deviating from the angle adjusting mechanism, of the inclined plate, the bottom plate is rotationally connected with the inclined plate, and the angle adjusting mechanism is matched, so that the inclination angle of the inclined plate can be flexibly adjusted according to the actual requirement for inclined hole punching of the industrial pump, and the punching requirements of different inclined holes are met; and meanwhile, the supporting assembly is arranged, the industrial pump on the inclined plate is further fixed, the stability of the industrial pump in the inclined hole punching process is enhanced, the positioning difficulty of operators is lowered, and the punching precision and quality are improved.
