Description

Three accurate expansions of three station pipe end processors, reducing mechanism

Technical field:

The utility model belongs to expansion, the reducing mechanism of all kinds of light-wall pipes on the pipe end processor, especially three adjustable accurate detent mechanisms of three stations.

Background technology:

Existing single station or multiple-site pipe end processing machine arrive φ 9.52mm as confidential the asking of single station to the copper pipe enlarging of φ 6mm, and time processing is not in place, though processing reluctantly, copper pipe or cracking, or owing to one-shot power is pressed from both sides not tight too greatly; And in the two station machines, station is non-adjustable, depends merely on machining accuracy and makes drift and clamping center remain consistent being difficult to realize.Because several of non-adjustable drift and clamping off-centrings also can influence the copper pipe quality of rushing out, or an eccentric or drum.Add the crudy that electric automation control can't guarantee product by the cylinder stroke so fully, must increase some micro-adjusting mechanisms.

Summary of the invention:

The purpose of this utility model is to provide three stations can three times adjustable, accurately accurately expands for three times of three station pipe end processors of location, reducing mechanism.

The utility model is achieved in that the accurate expansion of three times of a kind of three station pipe end processors, reducing mechanism, comprise a take-up housing and a thin type cylinder by electric control system control, transport by thin type cylinder at one, be provided with the drift holder along the slide block that slides on the take-up housing, it is characterized in that the drift holder is provided with three station drifts, on drift fixed block and slide block, be provided with the micromatic setting of realizing the drift left and right adjusting; In addition, on take-up housing, be provided with the micro-adjusting mechanism of the up-down adjustment that realizes three station drifts, this micro-adjusting mechanism comprises: be provided with one and act on the slide block first station hold-down screw between take-up housing bottom and slide block, realize that by regulating the first station hold-down screw location up and down of the first station drift is adjustable; On take-up housing, be provided with one by electric control system control, act on the spacing cylinder of second station of slide block, the gag lever post of this spacing cylinder is provided with the accent stroke nut, realizes that by the fine setting of transferring stroke nut the location up and down of the second station drift is adjustable; Be provided with adjustment screw at the end face of slide block and the correspondence position of take-up housing and slide block end face, realize that the location up and down of the 3rd station drift is adjustable.

Operation principle of the present utility model and advantage are described below: the drift fixed block is provided with three station drifts, and the enlarging of pipe end or reducing can divide and phase in for three times, so the product percent of pass height.In addition, key of the present utility model has been to realize that each station all is provided with the independent regulation device: be provided with the micromatic setting of realizing three station drift left and right adjusting on drift fixed block and slide block; On take-up housing, be provided with the micro-adjusting mechanism of the up-down adjustment that realizes three station drifts.In sum, because all adjustable accurate positioning of the utility model three stations, and simple in structure, easy to operate, solved eccentric, problems of crack in thin wall tubule expansion, the reducing, make the steady quality of processing tube reliable.

The specific embodiment:

With reference to figure 1, Fig. 2, as can be seen, the utility model is being achieved in that the thin type cylinder 1 that is connected with by electric control system control on a take-up housing 5 on the pipe end processor, transport by thin type cylinder 1 and connecting rod 6 thereof at one, the slide block 12 that slides up and down along the slide rail 10 of take-up housing 5 is provided with drift fixed block 16, this drift fixed block 16 is provided with three station drifts, be followed successively by the first station drift 13, the second station drift 15, the 3rd station drift 17, on drift fixed block 16, be provided with drift hold-down screw 8 and the lock drift screw 14 of realizing the drift left and right adjusting, on slide block 12, then be provided with and be used for the fixed block adjustment screw 18 of left and right adjusting drift fixed block, by regulating drift hold-down screw 8, lock drift screw 14 and realize finely tuning about above-mentioned three station drifts with deciding piece adjustment screw 18.In addition: first a station hold-down screw 7 that holds slide block 12 bottom surfaces is set between take-up housing 5 bottoms and slide block 12, realizes that by up-down adjustment the location up and down of the first station drift 13 is adjustable to the first station hold-down screw 7; A spacing cylinder 4 of second station of being controlled, acted on slide block 12 by electric control system is set on take-up housing 5, the gag lever post 2 of this spacing cylinder is provided with transfers stroke nut 3, realizes that by the fine setting of transferring stroke nut 3 location up and down of the second station drift 15 is adjustable; Be provided with adjustment screw 9,11 at the end face of slide block 12 and the correspondence position of take-up housing 5 and slide block end face, realize that the location up and down of the 3rd station drift 17 is adjustable.

Be transferred to consistent with the center of the folded processing tube 20 of workpiece clamping of pipe end processor the center of each station drift respectively before the life's work: be followed successively by first station, second station, the 3rd station from the bottom up.Realize finely tuning about three drifts by regulating with deciding screw 8, lock drift screw 14 and drift fixed block adjustment screw 18.With reference to figure 1, Fig. 3, realize by regulating hold-down screw 7 location up and down of the first station drift 13.With reference to figure 1, Fig. 2 and Fig. 4, the second station drift 15 is located up and down by the accent stroke nut 3 on the gag lever post 2 of regulating spacing cylinder 4 and is realized.When thin cylinder 1 moves to the position of second station, electric control system drives spacing cylinder 4 motions of two stations, realizes second station location, finish the action of two stations after, under the electric control system effect, spacing cylinder is return; With reference to figure 1, Fig. 2 and Fig. 5, the 3rd station drift 17 is located up and down by adjustment screw 9,11.After finishing the action of second station, slim cylinder continues motion, runs into adjustment screw 11 to adjustment screw 9 and stops, and finishes the action of the 3rd station.
