The invention discloses spiral rising type processing equipment with four sliding grooves. The spiral rising type processing equipment is used for processing a blank piece (1) into a worm and comprises a blank-piece bearing piece (2), a sleeve (3) with external threads, a driving sleeve (4) with internal threads and a rack (7), wherein the blank-piece bearing piece (2) is used for bearing the blank piece (1); relative to the sleeve (3) with the external threads, the upper end and the lower end of the blank-piece bearing piece (2) are respectively and fixedly arranged in the sleeve (3) with the external threads by an upper bearing (21) and a lower bearing (22) in an axial manner; the sleeve (3) with the external threads is matched in the driving sleeve (4) with the internal threads by threads; the lower end of the driving sleeve (4) with the internal threads can be rotatably arranged on the rack (7) by a thrust bearing (47); the rack is internally provided with a cavity (72).

The invention relates to a drilling machine head box. A transmission device comprises a steel gear (1) and a nylon gear (2) which are matched, the nylon gear (2) comprises an inner sleeve (21) and anouter gear (22), the inner sleeve (21) is made of nylon, and the outer gear (22) is made of the nylon and fiberglass. According to the drilling machine head box, the nylon gear is arranged in a splitmode, namely the inner sleeve and the outer gear, wherein the outer gear is made of the nylon and the fiberglass, in this way, the strength and abrasion resistance of the nylon gear are enhanced, theservice life of the nylon gear is prolonged, meanwhile, the structural form of the inner sleeve and the outer gear is adopted, the using cost of the nylon gear is also lowered, and the economical efficiency is quite good.

The invention discloses a worm processing mechanism with a lubricating-oil supplying system. The worm processing mechanism is used for processing a blank piece (1) into a worm and comprises a blank-piece bearing piece (2), a sleeve (3) with external threads, a driving sleeve (4) with internal threads and a rack (7), wherein the blank-piece bearing piece (2) is used for bearing the blank piece (1); relative to the sleeve (3) with the external threads, the upper end and the lower end of the blank-piece bearing piece (2) are respectively and fixedly arranged in the sleeve (3) with the external threads by an upper bearing (21) and a lower bearing (22) in an axial manner; the sleeve (3) with the external threads is matched in the driving sleeve (4) with the internal threads by threads; the lower end of the driving sleeve (4) with the internal threads can be rotatably arranged on the rack (7) by a thrust bearing (47).

The invention relates to the technical field of pipeline machining, in particular to a pressure pipeline inner wall polishing device which comprises an executing mechanism, a polishing mechanism, a polishing mechanism, a polishing mechanism and a polishing mechanism, the executing mechanism is of a regular polygon connecting rod structure formed by hinging a plurality of connecting rods, and polishing wheels are rotationally arranged at the hinged positions of the outer sides of the connecting rods; the driving mechanism is used for driving the regular polygon connecting rod structure to stretch. Spiral shafts are further rotationally arranged at the hinged positions of the outer sides of the connecting rods, and the spiral shafts and the polishing wheels are arranged at intervals. A first rotating wheel and a third rotating wheel are rotationally arranged at the outer side hinging position of the connecting rod and are arranged at an interval, and a second rotating wheel is rotationally arranged at the inner side hinging position of the connecting rod; the second rotating wheel and the first rotating wheel are in transmission through a transmission belt, and the second rotating wheel and the third rotating wheel are in transmission through a transmission belt; the spiral shaft is arranged on the first rotating wheel, and the polishing wheel is arranged on the third rotating wheel. The invention further discloses a pressure pipeline inner wall polishing method, pressure pipelines with different pipe diameters can be ground and polished, the structure is simple and compact, and the working efficiency is high.
