Problems solved by technology

However, when hot-melting, since the inner diameter of the spring 20 is greater than the diameter of the lower end surface 11 of the hot-melt column 10, the action point of the hot-melt does not act on the nut, but acts on the periphery of the nut, which is prone to the combination of the nut and the plastic part. The defect of not being tight, the nut is easy to loosen, and the stroke of the heat-melt column 10 is limited after the sleeve spring 20 is added, it is inconvenient to debug the stroke height of the heat-melt column 10 during debugging

Abstract

The invention discloses a buffer-type hot melting column used for hot melting a nut and implanting the nut into a plastic part. The buffer-type hot melting column comprises a connection body, a hot melting component, an elastic component and an adjusting component, wherein the connection body is of a columnar body; a through hole is formed in the connection body; an outer thread is formed in one end of the connection body; one end of the hot melting component is clamped to the through hole; the other end of the hot melting component extends out of the through hole in a direction being far away from the outer thread; the lower end surface of the other end of the hot melting component is matched with the size of the upper surface of a nut to be hot molten and implanted into a plastic part; the elastic component is arranged in the through hole; one end of the elastic component is propped against the hot melting component; and the adjusting component is arranged in the through hole and is propped against the other end of the elastic component. According to the buffer-type hot melting column, an action point directly acts on the nut during hot melting, so that the nut is closely integrated with the plastic part; the deformation of the elastic component at the interior can be conveniently controlled, so that the stroke height of the buffer-type hot melting column can be conveniently debugged; and the hot melting pressure injury can be effectively avoided.

Description

【Technical field】 [0001] The invention relates to a hot-melt tool, in particular to a buffer-type hot-melt column. 【Background technique】 [0002] The hot melt tool is a tool that uses hot melt to fix nut products, and is generally used in the process of product assembly. For example, the plastic casing of a laptop computer needs to be fixedly connected to the motherboard through metal nuts and screws. The metal nut must be melted into the plastic casing with a hot-melt tool first, so that the metal nut is fixedly combined with the plastic casing, and then screwed together. The motherboard is locked to the plastic case. [0003] see figure 1 As shown, the hot-melt column 10 of the prior art is integrally formed, and it is fixed on the upper template of the hot-melt machine. When performing hot-melt fixation on nut products, the plastic workpiece is first manually positioned on the lower template, and then placed The nut is placed on the hollow column of the plastic part, ...
