Detailed description of the invention
The detailed description of the invention of the present invention is described below.
As it is shown in figure 1, electric tube expander includes the front floating clamp 2 being provided with tube expander 1, front floating clamp 2 and the rear folder that floats
Tool 3 is in transmission connection by shaft coupling 10, and rear floating clamp 3 connects one end of torsion torque sensor 6 by axle 5, also coordinates on axle 5
Rotate in a circumferential direction axial displacement mechanism 4, and the other end of torsion torque sensor 6 connects the driving motor 7 that rotates in a circumferential direction；Also include for swollen
The first cylinder 8 of connecing and for tube expander 1, front floating clamp 2 and rear floating clamp 3 being transferred to the second cylinder 9 of station.
Shown in as shown in Figure 2, Figure 3 and Figure 4, the concrete structure of above-mentioned tube expander assembly 1 is as follows:
The first tube expander assembly 101 and the second tube expander assembly 102 with each other are constituted, the first tube expander assembly
101 and second tube expander assembly 102 arranged concentric.
Shown in as shown in Figure 2, Figure 3 and Figure 4, the concrete structure of above-mentioned front floating clamp 2 is as follows:
Including the heart seat 202 that rises coordinated with the second tube expander assembly 102, in one end matched in clearance chuck of the heart seat 202 that rises
Seat 205, at the side of chuck seat 205 affixed card disk cover 204, the opposite side in chuck seat 205 arranges gripper cylinder 2062, Yu Jia
The outfan holding cylinder 2062 distributes an affixed V-type claw 2061, and V-type claw 2061 and gripper cylinder 2062 constitute locking machine
Structure 206.As in figure 2 it is shown, above-mentioned V-type claw 2061 is symmetrical arranged centered by the center of circle of the heart seat 202 that rises.On card disk cover 204
The most uniform many support bars 207, guard shield 201 is affixed with card disk cover 204, before making by securing member, support bar 207
Floating clamp 2 is placed in the inside of guard shield 201.In card disk cover 204, also set up stage clip, chuck seat 205 is also offered square hole, on
Stating stage clip and square hole is easy to rise heart seat the dismounting of cap 203, the replacing making tube expander 1 is quick and convenient.
Shown in as shown in Figure 2, Figure 3 and Figure 4, the concrete structure of rear floating clamp 3 is as follows:
Including the flighty and impatient dynamic centering chuck 302 that rises being in transmission connection with the first tube expander assembly 101, at centering chuck axis 301
On along the circumferential direction stretch out formation one boss 3011, arrange in the periphery of boss 3011 and rise flighty and impatient dynamic centering chuck 302, in
One end of centering chuck axis 301 also matching thrust ball bearing 304, coordinates rotor 303, rotor in the periphery of thrust ball bearing 304
303 is bonded with one end of axle 5.As it is shown in figure 5, rise, flighty and impatient dynamic centering chuck 302 is oblate cylinder, in the flighty and impatient dynamic centering card that rises
The circle centre position of dish 302 offers perforate 3021, and perforate 3021 is square opening, and as shown in Figure 6, boss 3011 is square boss, square
With perforate 3021, the sectional area in hole ensure that centering chuck axis 301 can pass more than the sectional area of square boss, above-mentioned boss 3011
Torque delivery.
In the present invention, torsion torque sensor 6 is not subject to axial force, and it is solely subjected to circumference torsion in the course of the work, in axle
Also setting up plane bearing on 5, it is avoided that when rotating in a circumferential direction, torsion torque sensor 6 effect is made it bear axial force by external force
And damage.
The specific works process of the present invention is as follows:
Operationally, first it is transferred to refer to by the second cylinder 9 just tube expander 1, front floating clamp 2 and rear floating clamp 3
Determining station, external PLC arrives in above-mentioned each mechanism and sends the signal driving motor 7 that makes to rotate in a circumferential direction after station and start, torsion pass
Sensor 6, axle 5 and the axial displacement mechanism 4 that rotates in a circumferential direction are transmitted peripheral force and are made the rotor 303 in rear floating clamp 3 and thrust ball axle
Holding 304 rotations, the axial displacement mechanism that rotates in a circumferential direction 4 reduces axle 5 when circular motion, make this active force to move in the circumferential direction and
Axially-movable can be made, the most again peripheral force is transferred to the first tube expander assembly 101 by centering chuck axis 301, shaft coupling 10,
Make it make circumferential movement, before above-mentioned each mechanism does not arrives station, gripper cylinder 2062 control to make V-type claw 2061 clamp
Rise heart seat 202, and the first tube expander assembly 101 in tube expander 1 enters to be treated in tube expansion hole in a flash, gripper cylinder 2062 dozens
Open, make tube expander 1 be in quick condition and searching treats the center of circle of tube expansion, in now making tube expander 1 under the effect of the first cylinder 8
The first tube expander assembly 101 the most persistently import and treat tube expansion hole in, in the first tube expander assembly 101 axially displaced period
It drives the second tube expander assembly 102 to carry out tube expansion work, owing to the centering chuck axis 301 of rear floating clamp 3 passes through shaft coupling
10 are connected with the first tube expander assembly 101, because hereafter floating clamp 3 is passively sought center by the effect of front floating clamp 2.When swollen
After pipe process terminates, the outfan retraction of the first cylinder 8 makes the first tube expander assembly 101 of tube expander 1 exit and treats tube expansion pore
In, the outfan of the second cylinder 9 retracts and exits from station.
Above description is explanation of the invention, is not the restriction to invention, and limited range of the present invention sees right
Requirement, in the case of the basic structure of the present invention, the present invention can make any type of amendment.
