[0017] The present invention aims to provide a device that is arranged in a relay iron frame and a magnet assembly machine, and is used to carry and clamp the relay iron frame during the relay assembly process. Since the relay iron frame is a U-shaped frame structure, and the two iron frames of the U-shaped frame structure need to be symmetrically spliced ​​together to form a rectangular frame structure, and the two iron frames need to be placed vertically during the splicing process; based on the above assembly process requirements, the relative positions of the two iron frames are very likely to be relatively offset during the iron frame assembly process, affecting the assembly position accuracy; in addition, since the two iron frames are mutually spliced ​​structures and are in a relatively active state, when the magnets and core bodies are subsequently inserted into the rectangular frame structure formed by the iron frames, the positions of the two iron frames need to be clamped and fixed to avoid contact with the iron frames when the magnets and core bodies are inserted. Position offset; therefore, the present invention adopts a movable limiting groove to realize the support and limitation of the vertically placed iron frame, and forms a rectangular limiting groove matching the edge of the iron frame through the movable opening and closing of the two groups of movable clamping components, which limits the iron frame from the inside and outside; further, the two groups of movable clamping components of the present invention are closed by a flexible clamping method, and the elastic force is used to maintain the closing trend in the normal state. When the fixture needs to be opened, the inclined surface conduction method of the force is used to convert the same linear power into an oblique thrust for the two groups of movable clamping components, so as to complete the pushing and opening of the two groups of movable clamping components. Specifically, the present invention uses a horizontally arranged carrier as a bearing structure, a carrier block protruding upward is provided in the middle of the carrier, and two slide rails are provided on both sides of the carrier block at parallel intervals, and the movable seats of the two groups of movable clamping components are slidably embedded in the two slide rails, and a downwardly concave limiting groove is provided on the upper part of the movable seat, and a limiting strip groove is provided on the inner wall of the limiting groove according to the outline of the iron frame. The limiting strip grooves of the two movable seats are respectively docked with the limiting strip grooves on the carrier seat, and when the two movable seats are closed toward the central carrier seat, the limiting strip grooves are docked with each other to form a rectangular frame limiting groove body, which is used to limit the vertically inserted iron frame; in addition, upwardly protruding positioning columns are provided on the inner and outer sides of the rectangular limiting groove body, which are used to limit the iron frame from the inner and outer sides.

The inner end of the spring is connected to the inner wall of the slide groove, and the outer end is connected to the spring slide seat on the outside. The spring slide seat is fixed to the carrier seat through the outer fixed seat. In the natural state, the spring is in a compressed state. After being supported by the outer fixed seat, it has a tendency to drive the movable seat toward the central bearing block to maintain the clamping state of the iron frame.Furthermore, one end of the two movable seats is respectively connected to a roller seat, and the outer lower part of the roller seat is respectively rotatably connected to a roller. When the two movable seats are closed, the two rollers are driven to approach each other; when the jig needs to be opened, the first cylinder or the second cylinder is used to drive the first plug plate or the second plug plate to approach the two movable seats in a direction perpendicular to the slide rail. The first plug plate or the second plug plate is inserted from the two roller brackets close to each other, and after the inclined surface of its end portion contacts the two rollers, as the first plug plate or the second plug plate continues to be inserted, the two rollers are pushed apart, and the two rollers drive the two movable seats to move away from each other and open, thereby realizing the opening of the jig.

[0034] Furthermore, the present invention addresses the shortcomings and deficiencies of the prior art by independently developing and designing a relay frame and magnet assembly jig and assembly machine, which features elastic closing and clamping, as well as single-press opening, to secure the relay frame and magnet during assembly. Closing simultaneously forms a position-limiting and fixing structure that clamps both inside and outside, achieving precise positioning of the vertically placed frame. The present invention aims to provide a relay frame and magnet assembly jig, mounted within a relay frame and magnet assembly machine, for supporting and clamping the relay frame during relay assembly. Since the relay iron frame is a U-shaped frame structure, and the iron frames of the two U-shaped frame structures need to be symmetrically spliced ​​together to form a rectangular frame structure, and the two iron frames need to be placed vertically during the splicing process; based on the above assembly process requirements, the relative positions of the two iron frames are very likely to shift relative to each other during the iron frame assembly process, affecting the assembly position accuracy; in addition, since the two iron frames are mutually spliced ​​structures and are in a relatively active state, when the magnets and the core body are subsequently inserted into the rectangular frame structure formed by the iron frames, the positions of the two iron frames need to be clamped and fixed to avoid contact with the iron frames when the magnets and the core body are inserted. Position offset; therefore, the present invention adopts a movable limiting groove to realize the support and limitation of the vertically placed iron frame, and forms a rectangular limiting groove matching the edge of the iron frame through the movable opening and closing of the two groups of movable clamping components, which limits the iron frame from the inside and outside; further, the two groups of movable clamping components of the present invention are closed by a flexible clamping method, and the elastic force is used to maintain the closing trend in the normal state. When the fixture needs to be opened, the inclined surface conduction method of the force is used to convert the same linear power into an oblique thrust for the two groups of movable clamping components, so as to complete the pushing and opening of the two groups of movable clamping components.
