Mechanical telescopic type support ejector rod device

Abstract

The invention discloses a mechanical telescopic type support ejector rod device. The mechanical telescopic type support ejector rod device aims to achieve the effect that an inner decoration plate canbe reliably supported and to solve the problem that the inner decoration plate falls off before an adhesive is solidified. The device comprises a supporting pipe, a sliding ejecting supporting pipe which is arranged in the supporting pipe in a sliding mode, a sliding sleeve which sleeves the sliding ejecting supporting pipe in a sliding mode and an gap-eliminating locking mechanism; the sliding sleeve is located in the supporting pipe, and the outer side face of an elastic rubber sleeve abuts against the inner side face of the supporting pipe; the gap-eliminating locking mechanism comprises an outer strip-shaped guide hole which is formed in the outer side face of the supporting pipe and extends in the length direction of the supporting pipe, an inner strip-shaped guide hole which is formed in the outer side face of the sliding ejecting supporting pipe and extends in the length direction of the sliding ejecting supporting pipe, a radial bolt hole which is formed in the sliding sleeveand penetrates through the inner side face and the outer side face of the sliding sleeve, a locking screw which is matched with the bolt hole, a wire winding wheel which is located in the sliding ejecting supporting pipe and a connecting wire which is wound around the wire winding wheel.

Description

technical field [0001] The invention relates to a tooling for automobile production, in particular to a mechanically telescopic supporting ejector device for installing an automobile interior trim panel. Background technique [0002] The trim panels in the current vehicle body are mostly fixed on the inner side of the vehicle body by pasting. This kind of interior panel fixed on the inner surface of the vehicle body by pasting needs to install the interior panel support frame in the compartment of the vehicle body before the glue is cured, and the interior panel support frame is supported by the telescopic ejector rod on the interior panel support frame. panels to avoid the problem of trim panels falling off before the glue cures. The telescopic ejector rod of the current trim panel support frame usually uses set screws to fix the length of the telescopic ejector rod. The operation of this telescopic ejector rod is as follows. Manually extend the telescopic ejector rod so t...

Problems solved by technology

[0003] The current telescopic mandrel has the following deficiencies in the actual application process. There is often a gap between the end of the telescopic mandrel and the surface of the interior trim panel, and the telescopic mandrel cannot reliably support the interior trim panel, resulting in some interior trim The problem that the interior trim panel falls off during the glue curing process
