The invention relates to a device and a method for automatically riveting a movable spring assembly and a yoke iron. A riveting air cylinder (1) is fixed at the top part of the device and is connected with a riveting part (2) at the lower part; a fixing block (2-1) is arranged at the top part of the riveting part (2); an inlaying block (2-2), a middle block (2-4), a fixing screw rod (2-6) and a connecting block (2-8) are arranged sequentially below the riveting part (2); two punch needles (2-3) are connected at the middle part of the inlaying block (2-2); the middle block (2-4) is hollow, and a spring (2-5) is fixed in the middle of the top part of the middle block (2-4). The riveting air cylinder (1) is used to push the riveting part (2); when a contact module (2-7) at the lower end of the riveting part (2) is in contact with the to-be-riveted assembly of the movable spring (7) and the yoke iron (8), the counterforce of the spring (2-5) is used to push the contact module (2-7) to move upwards; meanwhile, convex hull splitting and riveting of the assembly of the movable spring (7) and the yoke iron (8) are realized by the punch needles (2-3) along with the riveting part (2) with inertia. The invention can solve the problem of automatic riveting between the movable spring assembly and the yoke iron in the prior art.
Description
technical field [0001] The invention belongs to the technical field of relay component automation, in particular to a device and method for automatically riveting a moving spring assembly and a yoke. Background technique [0002] There is a process in the relay production process to join the yoke and the moving spring. There are two options for the traditional production process: [0003] 1. One solution is spot welding, using the principle of electric welding machine capacitor charge and discharge, the upper and lower electrodes are respectively in contact with the moving reed and the yoke, and the two are joined by discharge. Program features: [0004] a. The required equipment is a spot welder. The electric welder itself has many shortcomings, and the charging and discharging circuit and trigger circuit are complex, fragile and inconvenient to maintain. [0005] b. The equipment is equipped with a high-voltage power supply, which has potential safety hazards. [0006]...
