Embodiment Construction

[0018] Such as figure 1 , figure 2 and image 3 As shown, the nozzle assembly of the automobile coating sealant extrusion gun includes two parts, the straight pipe 1 and the nozzle assembly. The gun nozzle assembly includes gun nozzle 5, locking spring 2, front limit block 3, rear limit block 4 and door limit limit rod 6. The front end of the gun nozzle 5 is stamped into a flat shape by a steel pipe to form a flat nozzle head 51, and the rear portion is a nozzle pipe 52, which is connected with the connecting straight pipe 1 by the connecting thread 7. The rear end outside of the flat nozzle 51 is covered with a front limit block 3, and the front limit block 3 is welded and fixed with it. After the front limit block 3, a rear limit block 4 is also covered with a front limit block. The block 3 and the rear limit stopper 4 are limitedly connected through the correspondingly provided limit slots 8 and limit blocks 9 at their adjacent ends. And the limit groove 8 and the limi...

Abstract

The invention relates to a sealant extruding gun nozzle assembly for automobile painting, which comprises a straight connecting tube and a gun nozzle assembly. The gun nozzle assembly comprises a gun nozzle, a locking spring, a front limit stop, a rear limit stop and a door side limit rod. The front end of the gun nozzle is a flat nozzle head and the rear part of the gun nozzle is connected with the straight connecting tube. The front limit stop and the rear limit stop are sheathed at the external part of the rear end of the flat nozzle head and are connected together at the adjacent ends in a limiting way. The door side limit rod is welded on the rear limit stop, forward extends to a position slightly higher than the top end of the gun nozzle and is arranged on the side of the flat surface of the flat nozzle head. The locking spring is sheathed on a nozzle tube at the rear part of the gun nozzle. The two ends of the locking spring respectively lean against the rear limit stop and the straight connecting tube. The gun nozzle assembly has the advantages of simple structure and convenient operation, and can facilitate painting the sealant on the fastening side of the automobile door.

Description

technical field [0001] The invention relates to the technical field of coating, in particular to a nozzle of a coating sealant extruding gun. Background technique [0002] Automobile coating extrusion sealant gun is widely used in the coating processing of door parts on the automobile body, mainly through the nozzle of the extrusion gun to spray paint on the processed parts. At present, the automotive coating extrusion sealant guns used in automobile factories are generally composed of a glue gun body and a circular straight tube nozzle. Mouth connected composition. When painting the car door, since the width of the buckle side of the car door is generally only about 10mm, the nozzle of the existing extrusion gun is too long and the facade is difficult to use, so it is easy to cause the gun and sealant to accumulate during operation. , Uneven glue shape and other defects. Contents of the invention [0003] The object of the present invention is to provide and design an ...
