[0021] In order to solve the load-bearing and positioning problem during the twisting process of the coil bracket and the iron frame, the present invention is designed with a twisting platform. The twisting platform uses a horizontal seat horizontally mounted on the horizontal support plate as a load-bearing structure. A core seat is provided on the upper part of the horizontal seat, and a core groove is provided in the middle part of the core seat. End grooves are provided at both ends of the core groove, which are recessed inward and pass through from top to bottom. The relay core is embedded in the core groove, and the coil brackets and the iron frame at both ends of the relay core are respectively embedded in the end grooves; an upwardly protruding block is provided on one side of the core groove, and the side wall of the block close to the core groove serves as a positioning reference surface. The positioning mechanism arranged on the other side of the twisting platform presses against the coil brackets and The iron frame is used to ensure the position stability of the relay core during the twisting process; a shaping groove that runs through the upper and lower parts is provided on the inner wall of the core groove close to the positioning mechanism. In order to ensure that the iron frame does not deviate during the twisting process, a lifting push piece is provided in the vertical direction on the driving seat below the cross seat. Before twisting, the lifting push piece passes through the cross seat and the core seat from below and extends into the shaping groove in the core groove. The lifting push piece moves upward with the driving seat and presses against the iron frame of the relay core from the inside. The iron frame is leveled and clamped from the inside and outside through the lifting push piece and the positioning mechanism, which ensures the position stability of the iron frame during the twisting process and the flatness consistency of the end face of the iron frame. Furthermore, the two sides of the cross seat of the present invention are respectively provided with horizontally extending side support platforms, and the side support platforms are provided with inwardly recessed sliding grooves; an end clamping block is provided horizontally and slidably in the sliding groove, and the end clamping block extends upward to the outer side of the end of the core seat, and an end clamping spring is horizontally connected between the end clamping block and the side wall of the cross seat.

The top inner wall of the driving block is connected to the end clamping block by a first inclined surface; when the driving cylinder pushes the driving seat upward, the driving seat synchronously drives the lifting push piece provided thereon and the driving block in the mounting groove to move upward synchronously. When the lifting push piece penetrates the shaping and positioning iron frame in the core body groove, the driving block converts the vertical direction power into the horizontal direction power through the first inclined surface, so as to drive the end clamping block to approach the core body groove, so that the end clamping block clamps the relay core in the positioning core body groove from the outside.The present invention is driven by a power of the driving cylinder, and simultaneously realizes the positioning and shaping of the iron frame and the clamping and fixing of the two sides of the relay core before twisting, effectively reducing power consumption, and has flexible adaptive clamping and fixing. After the upward power of the driving cylinder disappears, the end clamp block adaptively releases the relay core under the rebound force of the end clamp spring, thereby realizing automatic flexible clamping and releasing of the relay core.

[0022] The cam is fixed to the upper part of the support frame, and the cam is fixed on the upper part of the support frame, and the cam is fixed on the upper part of the support frame with an cam. The special feature is that a positioning sleeve is provided on the side of the first connecting seat, and a first push rod is inserted in the positioning sleeve. One end of the first push rod is connected to the first connecting seat, and the other end passes through the positioning sleeve and extends to the outside of the positioning sleeve, and its end is connected to a positioning block; first spring columns are respectively provided on both sides of the positioning sleeve, and the two first spring columns are respectively connected to a return spring, and the other end of the return spring is connected to the positioning support; in the natural state, the elastic force of the return spring tends to pull the first spring column to move outward, so that the positioning assembly moves away from the twisting platform so as to pick up and place the relay core on the twisting platform; when the positioning cylinder outputs upward power, the first inclined push seat is driven by the first inclined top seat to drive the positioning assembly close to the twisting platform so as to position the relay core. and a first spring is provided between the outward protruding parts on both sides of the first sleeve and the first end seat; and the first spring has a tendency to expand in the natural state, so as to drive the first end seat and the first push rod to move in the direction away from the first end seat; when the first push rod is moved toward the twisting platform by the power of the first connecting seat, the first push rod drives the first sleeve and the positioning block to approach the relay core, and provides elastic buffering through the first spring to realize flexible contact positioning of the relay core; the first sleeve pushes the first end seat and the positioning sleeve through the first spring, so that the positioning sleeve overcomes the pulling force of the reset spring and approaches the twisting platform in a linked manner, and provides secondary elastic buffering through the elastic force of the reset spring, so as to avoid damage to the relay core during the positioning process.

[0023] The present invention aims to solve the problem of twisted connection of connecting columns at both ends of a relay core body. A twisting mechanism is respectively provided at both ends of a twisting platform. The twisting mechanism is a mechanism for performing automatic twisting. The two sets of twisting mechanisms mainly include a transmission assembly and a twisting assembly.

The inner side of the twisting bracket is provided with a vertical slide groove which passes through the upper and lower parts. A second inclined top seat is slidably embedded in the vertical slide groove, and the top wall of the second inclined top seat is provided with an inclined top surface. When the lifting cylinder of the driving mechanism drives the two push columns arranged thereon to move upward through the lifting plate, the two push columns respectively push the second inclined top seats of the two sets of transmission assemblies from below, so that the two second inclined top seats move upward respectively. After the second inclined top seat converts the vertical direction power into the horizontal direction power through the inclined top surface, it drives the second inclined push seat to move horizontally in the horizontal support toward the twisting platform, so as to drive the twisting assembly connected thereon to approach the relay core body, and the second inclined push seat is guided and limited by the horizontal support. Furthermore, the twisted assembly is connected to the second inclined push seat through a second connecting seat, and the second connecting seat is connected to a second push rod through a connecting adjustment seat on the side close to the twisted platform, and the second push rod extends into the second twisted sleeve; second spring columns are horizontally provided on both side walls of the twisted sleeve, and the second spring columns are connected to the twisted support through a reset spring; in a natural state, the elastic force of the reset spring tends to pull the twisted sleeve outward, so that the twisted assembly is away from the twisted platform to facilitate the removal and placement of the relay core; when the lifting cylinder outputs upward power, the vertical power is converted into horizontal power through the inclined top surface, and then the twisted assembly is pushed to overcome the pulling force of the reset spring, and the twisted assembly is pushed toward the relay core to perform a twisted connection.Furthermore, the twisted sleeve of the present invention is a rectangular box-shaped structure with a horizontally through-groove in the middle, and both ends of the twisted sleeve are open, wherein a baffle is provided at one end close to the second oblique push seat, and a second end seat is provided at one end close to the twisted platform; the outer sleeve of the second push rod is provided with a second sleeve, and the second sleeve is a T-shaped block with outward-protruding protrusions on both sides, and a second spring is connected between the two protrusions and the second end seat respectively. When the second push rod drives the twisted top rod to twist the connecting column of the relay core, the second spring provides elastic buffering, so that the twisted top rod and the connecting column are in flexible contact, avoiding the difference in flatness of the connecting column surface or the position offset of the relay core due to rigid collision, thereby effectively improving the twisting quality; at the same time, when the second push rod drives the second sleeve to move toward the relay core, The second sleeve drives the twisted sleeve to stretch the reset spring, and the reset spring provides reverse elastic force to realize secondary elastic buffering; further, a third sleeve is provided on the side of the second end seat close to the twisted platform, and the third sleeve can be slidably sleeved on the sleeve protruding outward of the second end seat, and is connected to the second end seat through multiple third springs. An air seat is provided on the top of the third sleeve, and the air nozzle of the air seat is tilted downward through the third sleeve, which is used to blow high-pressure gas from the top to the twisted top rod passing through the bottom, so as to clean the surface of the twisted top rod during the activity and ensure its smooth activity; after the twisted top rod is close to the end face of the connecting column of the relay core, it continues to press against the connecting column, causing the connecting column to deform the material, and the material is squeezed and covered on the surface of the iron frame, so that the iron frame is twisted and connected to the coil bracket.
