Igniter miniature ring part multi-stage grabbing mechanism

Abstract

The invention relates to an igniter miniature ring part multi-stage grabbing mechanism. The miniature ring part multi-stage grabbing mechanism comprises at least two-stage suction cups and a grading plate. The first-stage suction cup is fixedly installed at the central position of a mounting plate. An inner hole of the second-stage suction cup forms shaft hole fit with the outer circle of the first-stage suction cup, the inner hole of each stage of suction cup outside the second-stage suction cup is matched with the grading plate mounted on the mounting plate, and a shell is installed on the outermost side in a sleeving mode. The suction cups except the first-stage suction cup perform axial limiting through steps arranged on the outer circular surfaces being in contact with the suction cups except the first-stage suction cup. Spray nozzles on the mounting plate communicate with air holes of the suction cups, and the adsorption is achieved by forming negative pressure on the outer end surface of each stage of suction cup. An air cylinder mounted on the mounting plate is used for pushing the suction cups except the first-stage suction cup to extend out, and the retraction of the suction cups is realized by introducing positive pressure into movable line cavities formed between the suction cups and adjacent structural members, so that the working adsorption area of the mechanism can be changed step by step. The igniter miniature ring part multi-stage grabbing mechanism realizes the completion of picking up ring parts of various sizes by a same machine head, the equipment flexibility is high, single control energy source is achieved, compatibility is good, the size and quantity of part picking devices in automatic equipment development can be effectively reduced, and the equipment development cost is reduced.

Description

technical field

[0001] The invention is used to realize the pick-up and assembly of the mini ring part of the igniter, and belongs to the field of pyrotechnics assembly. Background technique

[0002] The second-generation pyrotechnic igniter uses glass seals or tapered plugs as carriers, metal diaphragms as heating elements, and metal shells to restrict the output direction of ignition energy to achieve detonation and ignition. It has the advantages of insensitivity to electromagnetic signals, stable detonation, etc., and is widely used in strategic and tactical missile weapon systems, launch vehicles, satellites, fighter jets and other fields. The starting and firing components of control, booster separation, star-rocket separation and other devices.

[0003] For a long time, due to the characteristics of multiple varieties, small batches, and high assembly precision, pyrotechnic igniters are mainly assembled by hand. In order to meet the needs of automation to improve pr...
