Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
A kind of bolt welding system as shown in Figure 1, including a projection welder 1 as shown in Figure 2, several bolt conveyers
2nd, displacement sensor 4 and controller 3, have top electrode 5 and bottom electrode 7 on projection welder 1, bolt conveyer 2 is used for will be to be welded
Bolt is delivered on bottom electrode 7, and displacement sensor 4 is installed on projection welder 1, and displacement sensor 4 is used to detect bottom electrode 7
Displacement simultaneously produces displacement signal, and controller 3 is electrically connected with projection welder 1, several bolt conveyers 2 and displacement sensor 4；Control
Device 3 is equipped with technological parameter input terminal, and controls projection welder 1 and bolt defeated according to the technological parameter that technological parameter input terminal inputs
Send the operation and stopping of machine 2；Controller 3 can receive displacement signal, can input displacement signal and technological parameter input terminal
Technological parameter carry out contrast processing, and the operation and stopping of projection welder 1 and bolt conveyer 2 are controlled according to handling result.
Further, the quantity of bolt conveyer 2 is two, and two bolt conveyers 2 convey the bolt of different length respectively.
Further, bottom electrode 7 is equipped with bolt location structure 6.
Further, projection welder 1 is intermediate frequency projection welder.
Using the above scheme, several bolt conveyers 2 are respectively used to the bolt of conveying different size, and projection welder 1 is used to weld
Connecting bolt, controller 3 can be microcontroller, and displacement sensor 4 can make laser displacement sensor, laser displacement sensor is set
