Background technology
for the pipe fitting that caliber is larger, generally adopt at the larger annulus of a diameter now, cutter sweep can circumference be arranged on annulus movably, pipe fitting penetrates from circle ring center, along the telescopic location of the radiai adjustment cutter of annulus, and then realize cutting, because the diameter difference of different pipe fitting is apart from larger, when cutting different pipe fitting, the regulated quantity of knife rest will be made larger, the existing general structure by screw rod and threaded support seat realizes, and in order to avoid accidents such as shocks, need to arrange travel switch at threaded support seat along on the mobile route of screw rod, and at environment, under the factor impacts such as circuit, if travel switch surprisingly quits work, threaded support seat will be caused to move to and to install outside formation, impinge upon in other parts such as the reductor of device, cause damaging, affect operating efficiency.
Utility model content
for the technical deficiency of above-mentioned existence, the purpose of this utility model is to provide a kind of pipe fitting cutter sweep, it arranges the section of dodging respectively in two ends of external thread section on threaded rod, when something unexpected happened, threaded support seat moves to outside external thread section, can come off and be positioned at the section of dodging by screw thread, can not continue to move axially, and then the miscellaneous part of collision free device.
for solving the problems of the technologies described above, the utility model adopts following technical scheme:
a kind of pipe fitting cutter sweep, comprise bottom bracing plate, the knife rest on described bottom bracing plate can be arranged on movably by guiding parts, the tool rest on described knife rest can be arranged on movably, can be arranged on to telescopic adjustment the cutter on described tool rest, the driving mechanism that can drive described knife rest movement is provided with between described knife rest and described bottom bracing plate, described driving mechanism comprises by motor-driven threaded rod, with the threaded support seat of described threaded rod Screw assembly, described threaded support seat and described knife rest are fixedly connected, described threaded rod comprises the load segment that axially distributes successively, first section of dodging, external thread section, second section of dodging, described load segment is in transmission connection to described motor, described threaded support seat Screw assembly is on described external thread section, the diameter of the first described section of dodging, warp in the screw thread that the diameter of the second described section of dodging all is less than described threaded support seat, the axial length of the first described section of dodging, the axial length of the second described section of dodging all is greater than the axial length of described threaded support seat.
preferably, one end away from described external thread section of the second described section of dodging is provided with the stop part that can prevent described threaded support seat from coming off from described threaded rod.
further preferably, described stop part is the disk that a diameter is greater than the bottom diameter of described threaded support seat, and it releasably can be arranged on the end of described threaded rod by securing member.
preferably, described threaded support seat is arranged on the lower surface of described knife rest, two slipping parts that described guiding parts comprises the pair of guide rails be arranged on described bottom bracing plate, matches with the guide rail described in a pair respectively, the slipping part described in two is arranged on the lower surface of described knife rest and is distributed in the both sides of described threaded support seat.
the beneficial effects of the utility model are: the knife rest in the design can be arranged on threaded rod by threaded support seat movably, first section of dodging and second section of dodging are set respectively at the two ends of the external thread section of threaded rod, when threaded support seat surprisingly comes off from external thread section, can slide in first section of dodging or second section of dodging, can not continue again to move axially afterwards, thus avoid threaded support seat and miscellaneous part to clash into, reduce probability of damage, increase the service life, increase work efficiency.
