Detailed Description

Because the traditional welding gun threading is manually operated, the lead wire is manually plugged into the pipeline to penetrate to the other end of the pipeline, and then the copper wire is hooked on the lead wire and pulled back, the operation mode is very labor-consuming and low in efficiency, the copper wire is easy to scatter in the drawing process, and no full-automatic welding gun threading equipment exists in the current industry, and the welding gun threading equipment is a blank field, the automatic clamping device for the welding gun copper wire is designed, the specific structure of the automatic clamping device for the welding gun copper wire is shown in figures 1-5, the automatic clamping device comprises a machine base 1, the machine base 1 comprises a copper wire roller 2, a winding and buckling roller 3, a clamping and buckling strip 4, a copper wire conveying wheel set 5, a limiting hook 6, a pressure head 7, a cutter 8 and an infrared sensor 9, the clamping and buckling strip 4 is wound on the winding and buckling roller 3, one end of the clamping and buckling strip 4 passes through a buckling channel 11 to 7 of an adjusting seat 10, the clamping and buckling strip 4 consists of a plurality of buckling blocks, every knot piece 41 all is in rim charge 42 one side through connecting strip 43 homogeneous connection, connecting strip 43 with detain piece 41 and rim charge 42 and be integrative, only detain and have a groove on 41 with the connecting strip 43 junction, when the pressure head 7 pushes down, detain easy disconnection between piece 41 and the connecting strip 43, still be equipped with on the regulation seat 10 of pressure head 7 below and detain piece 41 assorted pressure seat 12, pressure head 7 is connected with the lift power supply 71 transmission that the driving pressure head 7 reciprocated, when the copper line all is located detain piece 41 with the lead wire, pressure head 7 will detain the piece 41 toward the pressure seat 12 internal pressure of below, detain piece 41 can be in the same place copper line and lead wire pressure, follow-up only need with the lead wire back draw can, 6 one end of spacing hook has the trend of resetting downwards and colludes on rim charge 42, the copper line on the copper line roller 2 passes the pressure head conveying wheel group 5 to 7 below.

The working principle is as follows: the copper wire that mainly twines on copper wire roller 2 is by the copper line that a plurality of tiny copper wires are constituteed, twine the winding on detaining the roller 3 and be the clip strip 4, the step that the copper line was carried to the intraductal is after the lead wire passes the pipe, firstly, when the copper line carried the recess of detaining piece 41 to the U type through copper line conveying wheel set 5, the lead wire passes pipe to infrared sensor 9 department, infrared sensor 9 can sense to central control system calculation lead wire and carry to detaining the distance on piece 41, when the lead wire carries to detaining in the piece 41 recess of detaining the U type, pressure head 7 can press whole detaining piece 41 with the below, detain on piece 41 presses the pressure seat 12 of below to, the knot piece 41 of U type can be in the same place copper line and lead wire pressure, finally, the lead wire can be automatic toward drawing, draw the pipe end after, the cutter 8 on the regulation seat 10 can cut off the copper line, the lead wire of detaining piece.

Copper line conveying wheel set 5 one side is equipped with discharging pipe 51, because the copper line comprises a plurality of copper wires, passes discharging pipe 51 to detaining the piece 41 when the copper line on, the copper wire can be comparatively loose, presses down to subsequent pressure head 7 and causes the influence, so be equipped with fluting 13 at discharging pipe 51 head end, is equipped with depression bar 14 on the fluting 13 (depression bar 14 is the one end that the spring was straightened, and the spring housing is on the screw rod), and depression bar 14 can press the copper wire together.

After the copper line is cut off, remain and can pull back at the copper line in the lead wire passageway 151, at this moment the screw rod can receive the drive of cylinder and rotate, and the screw rod can rotate the spring, and depression bar 14 is just natural rotation, and depression bar 14 just rotates to fluting 13 upper end, and the copper line just no longer receives pressing of depression bar 14.

Still be equipped with lead wire passageway 15 on adjusting seat 10, lead wire passageway 15 is the loudspeaker form, the entrance point of lead wire passageway 15 is towards cutter 8 one side, the exit end 151 of lead wire passageway 15 is towards detaining piece one side, whole lead wire passageway 15 is parallel with detaining piece 41, the entrance point is that the lead wire is worn out the one end that gets into lead wire passageway 15 from the pipe, exit end 151 is that the lead wire is worn out to detain the one end of piece 41 in following lead wire passageway 151, the aperture of entrance point is greater than the aperture of exit end 151, just so the lead wire can be more accurate carry to detaining the inslot of piece 41.

The limiting hook 6 is hinged on the adjusting seat 10 at the upper part of the buckling strip channel 11, the hook foot end 61 of the limiting hook 6 is hooked on the circular groove 16 of the rim material 42 between every two adjacent buckling blocks 41, a tension spring 17 is arranged between the upper part of the reset end 62 of the limiting hook 6 and the adjusting seat 10, the reset end 62 is also in transmission connection with a pressing power source 18 (cylinder) which drives the reset end 62 to move downwards, when the pressing head 7 presses downwards, the reset end 62 of the limiting hook 6 can be pressed downwards by the cylinder, the hook foot end 61 can be lifted, at the moment, the pressing head 7 can pull out the clamping buckling strip 4 in the buckling strip channel 11, after the buckling blocks 41 are pressed, the new buckling block 41 can be pulled to the lower part of the pressing head 7 again, finally, the cylinder does not press the reset end 62, the reset end 62 can receive the tension of the tension spring 17, and the hook foot end 61 can be hooked on the circular groove 16 of the rim material 42 again.

Detain piece 41 and be the U type, pressure head 7 bottom is seted up with detaining piece 41 assorted U type groove, and pressure seat 12 is the U type seat, detains piece 41 both sides and has evenly distributed's sand grip 19, and sand grip 19 can be better detain copper line and lead wire together.

Copper line conveying wheel group 5 includes upper wheel and lower wheel, and the upper wheel all overlaps with the lower wheel surface and has the one deck rubber layer, and the rubber layer can prevent to skid when copper line is carried, and the lower wheel is connected with the rotatory power supply (cylinder) transmission of drive lower wheel pivoted.
