Scanning expanding device as above, it is characterized in that described nut assembly 7 includes and the nut seat 71 that scans pedestal 4 and be fixedly connected with, in nut seat 71, be provided with rotationally nut sleeve 72, in nut sleeve 72, be fixedly connected with nut 73, this nut 73 is set in screw mandrel 3, one end of nut sleeve 72 is connected with gear 75, and the output of described the first drive motors 5 engages with gear 75; In nut seat 71, be provided with internal projecting ring 74, this internal projecting ring 74 limits nut sleeve 72 and departs from nut seat 71.
Scanning expanding device as above, it is characterized in that described pulse assembly 10 includes the gear 101 being hinged on scanning pedestal 4, on surface at gear 101 away from its central shaft, be provided with the first pin 102, on an expansion assembly 9, be provided with the second pin 103, between the first pin 102 and the second pin 103, be connected with arm-tie 104, described gear 101 engages with the output of the second drive motors 6.
Scanning expanding device as above, it is characterized in that a described expansion assembly 9 includes expands headstock 91, and described expansion headstock 91 is connected to and expands a guide rail 8, is provided with 2-4 expansion 92 on headstock 91 expanding.
Scanning expanding device as above, is characterized in that described expansion head is 2.
The present invention compared with prior art has the following advantages:
The enlarging that the present invention adopts the mode of scanning enlarging to process copper pipe carrys out " printing " enlarging as printer, and enlarging assembly is moved up and down fast, by expanding head, copper pipe is carried out to enlarging, the enlarging speed of processing copper pipe is very fast like this, saves a lot of time, and working (machining) efficiency is high.

[specific embodiment]
Describe the present invention below in conjunction with accompanying drawing:
As shown in the figure, scanning expanding device, includes support 1, is provided with guide rail 2 and screw mandrel 3 on support 1, and guide rail 2 is the guide rod of two balances, and screw mandrel 3 is placed between the guide rod of two balances.On guide rail 2, be provided with the scanning pedestal 4 slidably reciprocating along guide rail 2, the first drive motors 5 and the second drive motors 6 and nut assembly 7 on scanning pedestal 4.The first drive motors 5, the second drive motors 6 are stepper motor or servomotor or other motor.
Specifically, described nut assembly 7 is set on screw mandrel 3, described the first drive motors 5 be connected with nut assembly 7 and drive scanning pedestal 4 on guide rail 2, travelling backwards move.Also be provided with and expand a guide rail 8 at scanning pedestal 4, on an expansion guide rail 8, be provided with an expansion assembly 9 that can expand copper pipe bore.Described the second drive motors 6 is connected to expand on an assembly 9 and make to expand an assembly 9 pulses by pulse assembly 10 and moves up and down.
As preferably, described pulse assembly 10 includes the gear 101 being hinged on scanning pedestal 4, on surface at gear 101 away from its central shaft, be provided with the first pin 102, on an expansion assembly 9, be provided with the second pin 103, between the first pin 102 and the second pin 103, be connected with arm-tie 104, described gear 101 engages with the output of the second drive motors 6.Gear 101 is equivalent to realize the function of cam like this, under the effect of gear 101, makes to expand an assembly 9 and constantly realizes and moving back and forth, and realization is expanded an assembly 9 and moved up and down.
Described nut assembly 7 includes and the nut seat 71 that scans pedestal 4 and be fixedly connected with, in nut seat 71, be provided with rotationally nut sleeve 72, in nut sleeve 72, be fixedly connected with nut 73, this nut 73 is set in screw mandrel 3, one end of nut sleeve 72 is connected with gear 75, and the output of described the first drive motors 5 engages with gear 75.In nut seat 71, be provided with internal projecting ring 74, this internal projecting ring 74 limits nut sleeve 72 and departs from nut seat 71.Like this, the first drive motors 5 rotates by gear driven nut sleeve 72, nut sleeve 72 drives nut 73 to rotate, and nut 73 is set on screw mandrel 3, and screw mandrel 3 is to be fixed on support 1, screw mandrel 3 can reaction forces to nut 73, and internal projecting ring 74 limits nut sleeve 72 and departs from nut seat 71, like this, the driving of the first drive motors 5 will make to scan pedestal 4 and slidably reciprocating along guide rail 2.
As the optimal way of the present embodiment, a described expansion assembly 9 includes and expands headstock 91, and described expansion headstock 91 is connected to and expands a guide rail 8, is provided with 2-4 expansion 92 on headstock 91 expanding.
As the optimal way of the present embodiment, described expansion 92 is 2.
Like this, scanning expanding device is on one side under the driving of the first drive motors 5, and scanning pedestal 4 slides on guide rail 2, and under the driving of the second drive motors 6, makes to expand an assembly 9 pulses to move up and down, and realizes the expanding of scan-type.
