Description

Technical Field

[0001] This invention relates to the field of relay processing, specifically to a core pressing device for relay assembly processing. Background Technology

[0002] A relay is an electrical control device that causes a predetermined step change in the controlled quantity in the electrical output circuit when the change in the input quantity (excitation quantity) reaches a specified requirement. It has an interactive relationship between the control system (also known as the input circuit) and the controlled system (also known as the output circuit). It is usually used in automated control circuits. In fact, it is an "automatic switch" that uses a small current to control a large current. Therefore, it plays the roles of automatic adjustment, safety protection, and circuit switching in the circuit. The relay is mainly composed of a coil, winding drum, iron core, magnetic yoke, spring, adjusting nut, armature, etc. During the assembly and processing of the relay, the iron core must be pressed into the coil.

[0003] Currently, the iron core pressing device used for relay assembly and processing makes hard-to-hard contact between the electric chuck and the iron core when clamping the iron core, which can easily damage the iron core, resulting in an uneven surface of the iron core and seriously affecting the accuracy of the relay. Furthermore, clamping and pressing are carried out in two separate processes, which makes the assembly and processing slow and inefficient, seriously affecting production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a core pressing device for relay assembly processing, thereby solving the problems mentioned in the background art. To achieve the above objective, this invention provides the following technical solution: a core pressing device for relay assembly processing, comprising two side support plates, a crossbeam, a pushing mechanism for driving the movement of a clamping mechanism, a clamping mechanism for feeding materials, and a pressing mechanism for pressing the core. A crossbeam is welded between the tops of the two side support plates, a pushing mechanism is provided on the crossbeam, and multiple clamping mechanisms and pressing mechanisms are provided below the pushing mechanism.

[0005] Preferably, the propulsion mechanism includes a first hanging plate, a horizontal propulsion cylinder, a push plate, a hanging platform, a vertical lifting cylinder, and a support platform.

Clamping blocks are fixed to the inner ends of the tamping rods, and springs are also fitted onto the tamping rods. The pressure-applying mechanism is located on the base plate.

[0007] Preferably, the pressure applying mechanism includes a pressing cylinder and a circular pressure plate. The pressing cylinder is fixed at the bottom center of the substrate, and the pressure plate is fixed on the extended end of the pressing cylinder, with the pressure plate located directly above the two clamping blocks.

[0014] The beneficial effects of the present invention compared with the prior art.

[0015] In this invention, a propulsion mechanism is provided below the crossbeam to move the support platform laterally and vertically, which helps to adjust the orientation of the clamping mechanism, thereby facilitating the precise clamping of the iron core and making it easier to accurately insert it into the winding drum for assembly.

[0016] In this invention, multiple clamping mechanisms are provided below the support platform. Clamping cylinders push the clamping blocks closer together, thereby clamping the iron core with the clamping blocks. During the clamping process, springs can be used to buffer the clamping force, and rubber pads are used to protect the iron core. This effectively avoids damaging the iron core, ensures the iron core surface is flat, and guarantees the accuracy of the relay.

[0035] Invention and advantages: The operation steps of this iron core pressing device for relay assembly are as follows:

[0036] Step 1: Install this pressing device on the production line, keeping the support platform 8 parallel to the production line so as to accurately clamp the iron core on the production line. Electrically connect the horizontal pushing cylinder 4, the vertical lifting cylinder 7, the clamping cylinder 14, and the pressing cylinder 19 to the control panel to control the stroke and movement of the cylinders, thereby achieving automated operation and completing the installation.

[0037] Step 2: During clamping and pressing operations, activate the vertical lifting cylinder 7 to extend it, thereby lowering the support platform 8 and the clamping mechanism below it, so that the two clamping blocks 16 in the same group are located on both sides of the iron core. Then, activate the two clamping cylinders 14 in the same group to extend them, thereby pushing the two clamping blocks 16 to move towards each other, thus clamping the iron core. During the clamping process, the spring 18 is used to buffer the clamping force, and the rubber pad 23 is used to protect the iron core, which can effectively avoid damaging the iron core, ensure the surface of the iron core is flat, and ensure the accuracy of the relay.

[0038] Step 3: Activate the horizontal propulsion cylinder 4 to extend it, thereby moving it laterally against the support platform 8 and moving the iron core clamped at its bottom directly above the winding coil. Then activate the pressing cylinder 19 to extend it, using the pressure plate 20 to press down on the iron core. At the same time, retract the clamping cylinder 14 to disengage the clamping block 16 from the iron core, thereby accurately pressing the iron core into the winding coil. The integrated structural design greatly improves the assembly and processing speed and production efficiency.
