Adopt the present invention of technique scheme, compared with prior art, its outstanding characteristics are:
By installing balanced body additional at welding electrode, come balance by balance staff or offset gravity or the centrifugal force of welding electrode self with the gravity of balanced body self and the centrifugal force that when welding electrode is worked, produces, make welding electrode that the welding pressure that is close to balance can be provided in the whole circumference scope, at this moment have ready conditions fully and reduce welding pressure and welding current, thereby realize truly energy-saving and cost-reducing.
The present invention further technical scheme is: be connected with connecting plate between the described gripper shoe of two correspondences, electrode travel be housed on the described connecting plate regulate bolt.
Adopt the present invention of said structure, its beneficial effect is: under the prerequisite of welding electrode constant pressure, install electrode travel additional at connecting plate and regulate bolt, make the welding electrode volume under pressure precisely controlled, so only rotate to the position that longitudinal rib is arranged (the high point of cage muscle position) at welding electrode, welding electrode just effectively contacts with the hoop muscle, and rotation is during to the low dot location between two longitudinal ribs, the welding electrode plate contacts hardly with circumferential reinforcement, it is very little to wear and tear, and is further prolonged the service life of welding electrode plate like this.
The present invention further technical scheme can also be: add eccentric shaft between the described gripper shoe of two correspondences, the excentric sleeve of control electrode swing is housed on the described eccentric shaft, on the described excentric sleeve handle is housed.
Adopt the present invention of said structure, its beneficial effect is: only need pull handle, excentric sleeve is rotated to the offset maximum position, just can conveniently wear muscle, unload cage and shearing ring to muscle.

The specific embodiment
The invention will be further described below in conjunction with embodiment, and purpose only is to understand better content of the present invention.
Referring to Fig. 5, the described pile tube seam welder of present embodiment rotating welding electrode structure, its gripper shoe 4 is formed the clamping plate type supporting construction by draw money on credit fagging and short gripper shoe, and fixedly connected with a silk steel governor motion 3 by the fagging of drawing money on credit, drawing money on credit is equipped with a balance staff 11 and an eccentric shaft 15 between fagging and the short gripper shoe; Conductive electrode plate 5 and welding electrode plate 6 are fitted together by positioning sleeve 10, be installed in one with the affixed stiffener 17 of balance staff 11 on; The spring positioning component is made up of spring limiting board 7, spring backstay 8, spring 9 and spring adjusting nut, spring limiting board 7 is assemblied on the clamping plate type supporting construction of being made up of draw money on credit fagging and short gripper shoe, spring backstay 8 is installed on the spring limiting board 7, spring backstay 8 is hinged with stiffener 17 1 ends, and stiffener 17 other ends are equipped with balanced body 18; Be connected with connecting plate 13 on the clamping plate type supporting construction of being formed by draw money on credit fagging and short gripper shoe, electrode travel adjusting bolt 12 is housed on the connecting plate 13; Excentric sleeve 16 is housed on the eccentric shaft 15, handle 14 is housed on the excentric sleeve 16.
The constant relatively principle of electrode pressure in the welding electrode course of work is described below in conjunction with Fig. 5, Fig. 6, Fig. 7, Fig. 8.
When pad is positioned at peak, as shown in Figure 5, welding electrode is subjected to downward spring pressure F3, the gravity F2 of welding electrode itself, the negative pressure that the electrode centrifugal force F1 of balance staff 11 both sides, balanced body 18 centrifugal force F4 and balanced body 18 gravity F5 produce, balance staff 11 both sides centrifugal force F1, the F4 while can ignore in the center of circle dorsad, the pressure that electrode gravity F2 produces and the negative pressure of the electrode of balanced body 18 gravity F5 be also near balance, so the pressure F3 that only produces from spring of the pressure that is subjected to of pad.
When pad was positioned at minimum point, as shown in Figure 8, welding electrode was subjected to spring pressure F3 upwards, and the gravity F2 of electrode itself changes into the negative pressure to pad, and balanced body 18 gravity F5 produce the normal pressure to pad, and both balance each other.Centrifugal force F1, F4 that balance staff 11 both sides produce also are mutual balances, so the electrode pressure that pad really is subjected to still is spring pressure F3.
During two horizontal levels, as Fig. 6, shown in Figure 7, electrode gravity F2 and the electrode pressure of balanced body 18 gravity F5 be not influence almost about pad moves to, and the centrifugal force F1 that electrode produces also can ignore the stressed spring pressure F3 that remains of pad.
In the present embodiment, under the prerequisite of welding electrode constant pressure, install electrode travel additional at connecting plate 13 and regulate bolt 12, make the welding electrode volume under pressure precisely controlled, so only rotate to the position that longitudinal rib 1 is arranged (the high point of cage muscle position) at welding electrode, welding electrode just effectively contacts with hoop muscle 2, and rotation is during to the low dot location between two longitudinal ribs 1, welding electrode plate 6 contacts hardly with hoop muscle 2, it is very little to wear and tear, and is further prolonged the service life of welding electrode plate 6 like this.
In addition, install stiffener 17 additional at conductive electrode plate 5, further increased conductive electrode intensity, optimized the conductive electrode stress condition, make the conductive electrode plate obtain prolonging 5 service lifes.
In the present embodiment, by installing eccentric shaft 15 and excentric sleeve 13 and handle 11 additional, more conveniently wear muscle, unload cage and shearing ring to the operation of muscle.
