Positioning dispensing gun

Abstract

The invention relates to a positioning dispensing gun which comprises a dispensing gun pipe, a sliding rail, a positioning rod, a single-row radial ball bearing and a thumb screw, wherein the sliding rail is vertically welded on the dispensing gun pipe; the positioning rod and the dispensing gun pipe are arranged in parallel, the lower end of the positioning rod is sleeved in the sliding rail, and the upper end of the positioning rod is higher than the pipe mouth of the dispensing gun pipe; the single-row radial ball bearing is sleeved on the upper end of the positioning rod; and the thumb screw is arranged at the tail of the positioning rod and screwed for fixing the positioning rod on the sliding rail. The section of the sliding rail is concave, and the lower part of the positioning rod is provided with a concave hole and sleeved in the sliding rail. The outer ring of the single-row radial ball bearing is provided with a groove. The positioning rod slides on the sliding rail for regulating the dispensing position, and the single-row radial ball bearing is used for positioning, thus the positioning dispensing gun can adapt to the dispensing on a position with any width, ensures that a dispensing pen is straight and uniform, avoids the lathe glue leakage problem caused by poor dispensing of the glue, reduces the dispensing time and lowers the labor cost.

Description

technical field [0001] The invention belongs to the field of glue sealing tools for flat welded parts of automobiles, and in particular relates to a novel positioning glue extrusion gun. Background technique [0002] In the production process of automobile body-in-white, various welded parts are assembled and welded together. Some parts need to be waterproof, so sealant must be squeezed. For example, a sealant about 40 cm long needs to be squeezed at the lap joint between the rear wheel bulge and the rear floor. , because the overlap of the floor is only 1 cm, the sealant is required to be straight and cannot exceed the range of 1 cm. However, because the current glue gun is just a tapered barrel, the barrel is smooth and straight, and there is no positioning device on the barrel head. The worker holds the gun barrel and applies the outflowing glue on the parts. Without a positioning device, it will cause extrusion. The glue is not in place, the glue squeezed on the part is...

AI Technical Summary

Problems solved by technology

However, because the current glue gun is just a tapered barrel, the barrel is smooth and straight, and there is no positioning device on the barrel head. The worker holds the gun barrel and applies the outflowing glue on the parts. Without a positioning device, it will cause extrusion. The glue is not in place, the glue squeezed on the part is uneven, not straight or intermittent

At the same time, the workers are slow in the extrusion process, and the extrusion time increases, which increases the labor cost
