Abstract

The invention discloses a pin removal device, and belongs to the field of aircraft manufacturing tools. The pin removal device comprises a connecting rod, a sliding part, a pin pulling head and an abutting part, wherein the sliding part moves along an axial direction of the connecting rod; the pin pulling head and the abutting part are arranged at two ends of the connecting rod respectively; the sliding part can be abutted to the abutting part; the pin pulling head is provided with a clamping part; and the clamping part can be clamped with a lower end face of the head of a pin. When the sliding part moves along the connecting rod and collides with the abutting part, the pin pulling head clamped with the lower end of the pin head generates upward force on the pin, so that the pin can be pulled out easily.

Description

Technical field [0001] The invention relates to the field of tools for aircraft manufacturing, in particular to a pin taking device. Background technique [0002] The production of aircraft parts requires the guarantee of molds. Before the upper and lower molds of the aircraft parts work together, the parts need to be accurately placed on the mold. Pins are generally used to ensure accurate positioning of the parts on the mold. The mold and the part are provided with a plurality of positioning holes corresponding to each other, the part is placed on the mold, and the pins are inserted into the positioning holes of the part and the mold in turn to complete the positioning of the part. [0003] There is a gap between the lower end surface of the pin head and the upper surface of the part. In the prior art, a crowbar is generally inserted into the gap between the pin head and the part, and the crowbar is manually moved to pull out the pin. Since the pin fits tightly with the mold a...
