Description

Technical Field

[0001] This utility model relates to the field of electromagnetic valve manufacturing technology, and more specifically, to a riveting fixture for electromagnetic valve cores. Background Technology

[0002] In the production process of solenoid valves, the riveting of the iron core is one of the key steps. The iron core needs to be tightly connected with components such as the armature and spring to ensure that the solenoid valve can operate normally when energized and de-energized. Traditional iron core riveting methods mostly use manual riveting or simple riveting equipment. Manual riveting is labor-intensive, inefficient, and the riveting quality is greatly affected by the worker's skill level and working condition, which can easily lead to problems such as insecure riveting and misalignment between the iron core and components, resulting in unstable solenoid valve performance and a high defect rate. To address this, we designed a solenoid valve iron core riveting fixture. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a solenoid valve core riveting fixture to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a solenoid valve core riveting fixture, including a processing table, an L-shaped support plate fixed on one side of the processing table, a hydraulic telescopic rod fixedly installed on the upper side wall of the L-shaped support plate, a lower plate fixedly installed below the hydraulic telescopic rod, a plurality of riveting heads fixed at intervals below the lower plate, and a positioning mechanism installed directly above the processing table.

[0005] As a preferred embodiment of this utility model, a side plate is fixed to one side of the lower plate, and a buffer mechanism is fixed above the processing tables on both sides directly below the side plate.

[0006] As a preferred embodiment of this utility model, the buffer mechanism includes a sleeve and a slide rod. The slide rod is fixed above the processing table, the sleeve is sleeved above the slide rod, and a rod limiting plate is fixed above the slide rod. A spring is sleeved on the slide rod.

[0007] As a preferred technical solution of this utility model, the positioning mechanism includes a hexagonal base and a hexagonal cover plate. The hexagonal base is fixedly installed above the processing table. Multiple grooves are provided on the upper part of the hexagonal base. The hexagonal cover plate is placed on the upper part of the hexagonal base, and multiple insertion mechanisms are connected between the side wall of the hexagonal cover plate and the hexagonal base. Insertion holes are provided on the hexagonal cover plate directly above the multiple grooves.

[0008] As a preferred embodiment of the present invention, the insertion mechanism includes a slotted plate and an insert plate. The slotted plate is fixed to the side wall of the hexagonal cover plate, and the insert plate is fixed to the side wall of the hexagonal base, with the insert plate inserted into the slotted plate.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. This utility model can position multiple iron cores through a positioning mechanism, and can drive multiple riveting heads to move downward by controlling the hydraulic telescopic rod. When the riveting head comes into contact with the iron core, it can rivet it.

[0011] 2. When the riveting head moves downward, the side plate will come into contact with the buffer mechanism. The buffer mechanism can buffer the riveting head to prevent excessive downward pressure from the riveting head, which could damage the iron core. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 4As shown, this utility model provides a solenoid valve core riveting fixture, including a processing table 1, an L-shaped support plate 2 fixed on one side of the processing table 1, a hydraulic telescopic rod 3 fixedly installed on the upper side wall of the L-shaped support plate 2, a lower plate 4 fixedly installed below the hydraulic telescopic rod 3, and multiple riveting heads 5 fixed at intervals below the lower plate 4. A positioning mechanism is installed directly above the processing table 1, which can position multiple cores. By controlling the hydraulic telescopic rod 3, multiple riveting heads 5 can be moved downward. When the riveting heads 5 come into contact with the core, they can be riveted.

[0019] Among them, a side plate 6 is fixed on one side of the lower plate 4, and a buffer mechanism 7 is fixed on both sides of the processing table 1 directly below the side plate 6.

A spring 73 is sleeved on the slide rod 72. The spring 73 can convert the force received into elastic potential energy to achieve the buffering effect. When the riveting head moves downward, the side plate will contact the buffer mechanism. The buffer mechanism can buffer the riveting head 5.

[0020] The positioning mechanism includes a hexagonal base 8 and a hexagonal cover plate 9. The hexagonal base 8 is fixedly installed above the processing table 1. Multiple grooves 14 are provided on the upper part of the hexagonal base 8. The hexagonal cover plate 9 is placed on the upper part of the hexagonal base 8, and multiple insertion mechanisms are connected between the side wall of the hexagonal cover plate 9 and the hexagonal base 8. Insertion holes 10 are provided on the hexagonal cover plate 9 directly above the multiple grooves 14. By placing multiple iron cores in the multiple grooves 14 and then covering them with the hexagonal cover plate 9, one end of the multiple iron cores will extend upward through the insertion holes 10. When the riveting head 5 contacts the iron core, it can be riveted.

[0021] The insertion mechanism includes a slot plate 11 and an insertion plate 12. The slot plate 11 is fixed to the side wall of the hexagonal cover plate 9, and the insertion plate 12 is fixed to the side wall of the hexagonal base 8.
