Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 6, a welding apparatus for a truck sub-frame includes:

a platform 1 capable of supporting a subframe; is the supporting base of the whole device. The base plate 5 is arranged on the platform 1, and the base plate 5 can support a connecting beam of the auxiliary frame; the first side of the platform 1 is provided with a series of side positioning seats 2, and the side positioning seats 2 can position the first side of the auxiliary frame; a series of side positioning cylinders 3 are arranged on the second side of the platform 1, press blocks 4 are arranged on piston rods of the side positioning cylinders 3, and the press blocks 4 can be matched with the second side of the auxiliary frame; through the first side of 2 location sub vehicle frames of side positioning seat, the opposite side that the side location cylinder 3 and the briquetting 4 of rethread opposite side compressed tightly the sub vehicle frame plays the effect that stably compresses tightly the location.

And the hinge shaft positioning seat 8 is arranged at the tail end of the platform 1, and the hinge shaft positioning seat 8 can be matched with a hinge shaft of an auxiliary frame. The function of positioning the hinge shaft at the end part of the auxiliary frame is realized.

The positioning platform is characterized by further comprising a positioning seat, wherein the positioning seat is arranged near the middle of the platform 1, a positioning pin is arranged on the positioning seat and is matched with a middle positioning hole of the auxiliary frame, and the middle of the auxiliary frame is positioned through the positioning seat in the middle and the positioning pin matched with the middle positioning hole of the auxiliary frame, so that the auxiliary frame with longer length is positioned in the middle in an auxiliary manner.
