[ detailed description ] embodiments
The first embodiment is as follows:
referring to fig. 1 to 4, a welding device 100 capable of effectively preventing a projection nut from being placed upside down includes a support 1, a lower electrode 2 fixed on the support 1, a positioning pin seat 3 disposed on the lower electrode 2, an upper electrode module 4 located above the lower electrode 2, a driving member 5 for driving the upper electrode module 4 to move up and down, a bolt 6 fixed on the upper electrode module 4, and an inductor 7 fixed on the support 1 and capable of inducing the bolt 6 at a predetermined height position.
The upper electrode module 4 includes an electrode energizing module 41 fixed to the movable end of the actuator 5, an upper electrode mounting rod 42 fixed to the electrode energizing module 41, and an upper electrode block 43 fixed to the upper electrode mounting rod 42. The upper electrode block 43 is a ring structure in which an avoiding hole 431 for avoiding a nut protrusion is formed. The diameter of the relief hole 431 is larger than the diameter of the projection nut and smaller than the diameter of the flange portion of the projection nut.
An insulating block 8 is fixedly arranged on the electrode electrifying module 41, and the bolt 6 is fixed on the insulating block 8 through a first fixing nut 9. Through the setting of insulating block 8, it is insulating to have ensured between bolt 6 and the electrode circular telegram module 41, improves the security, and ensures that inductor 7 can normally respond to.
