Dual suction type mechanical core

Abstract

The invention discloses a double-suction machine core, comprising substrate, disc suction driving mechanism, press disc mechanism, active piece, push plate, planetary plate, locking plate and limiting piece, where the active piece is installed on the substrate and able to laterally make horizontal movement under the drive of the disc, and the active piece makes the push plate reversely move through linkage piece, the push plate is made with limiting groove, the planetary plate is in a lever structure and the pivot of the lever is located in the limiting groove and the force bearing end of the lever is located on the moving track of the disc, and the forcing end of the lever drives the locking plate to move, the locking plate has a first locking piece whose moving track is provided with a second locking piece, the limiting piece is between the press disc and planetary plate and can be rotatablely arranged on the substrate and has a limiting column and spring piece to reset the limiting column, the push plate is equipped with a push part to rotate the limiting column, and the position on the substrate corresponding to the limiting column is equipped with channel. And the machine core has high location accuracy and can implement suction of large and small discs.

Description

technical field [0001] The invention relates to the field of double-suction movement. Background technique [0002] In the prior art, in order to be able to suck large and small discs, people have designed a double-sucking movement, which is widely used in electronic products such as high-end DVDs, LCD TVs, PCs, and car-mounted CD players. . At present, there are many types of suction-type movement in the market, which are divided into two categories: metal structure and plastic structure. [0003] The metal suction movement has the advantages of achieving large and small disc suction, thinning and high temperature resistance, but its mechanism is complicated, which leads to high failure rate and high cost, which greatly weakens its market competitiveness. [0004] The plastic suction movement has the advantages of realizing large and small dish suction and having a price advantage, but its structure is complex, its thickness is 3-5mm thicker than that of the metal movemen...
