Disclosure of Invention
Utility model purpose: the utility model provides a novel go up swivel nut frock to the swivel nut drops when preventing to back to twist.
The technical scheme is as follows:
first aspect provides a novel swivel nut frock of going up, includes: mobile jib, pressure head, wherein, the mobile jib includes application of force section and screw rod section, and wherein the junction of application of force section and screw rod section is provided with radial outside boss, and the length of screw rod section is less than pressure head degree of depth and swivel nut degree of depth sum, and the pressure head is tubular structure and inside is provided with the internal thread the same with the swivel nut, and the pressure head outside is provided with spacing portion for prevent that the mobile jib from screwing out the rotation of in-process pressure head.
Further, the pressure head outside is provided with spacing portion, specifically includes: the outer side of the pressure head is provided with a screwing arm or a hexagonal structure.
Further, still including revolving to twist the pole, wherein the application of force section tip of mobile jib is provided with radial through-hole, revolves to twist the pole and passes radial through-hole is used for driving the mobile jib motion.
Further, the screwing rod is in interference fit with the radial through hole of the main rod.
Further, the outer diameter of the lower end of the pressure head is smaller than the outer diameter of the upper end of the screw sleeve so as to avoid interference with the upper end of the screw sleeve.
Further, two screwing arms are arranged on the outer side of the pressure head, and the two screwing arms are circumferentially and symmetrically arranged.
Has the advantages that: the utility model discloses a separation piece is made with spacing part and the internal thread frock of screwing to the frock, plays the reverse spacing to the swivel nut equally through reverse afterburning spacing part when anti-intermediate peashrub dismantles, prevents that the swivel nut from droing.

Detailed Description
In order to solve the problem, the utility model provides a novel go up swivel nut frock, include: mobile jib, pressure head, wherein, the mobile jib includes application of force section and screw rod section, and wherein the junction of application of force section and screw rod section is provided with radial outside boss, and the length of screw rod section is less than pressure head degree of depth and swivel nut degree of depth sum, and the pressure head is tubular structure and inside is provided with the internal thread the same with the swivel nut, and the pressure head outside is provided with spacing portion for prevent that the mobile jib from screwing out the rotation of in-process pressure head.
In another possible embodiment, the outside of the pressure head is provided with a limiting part, which specifically comprises: the outer side of the pressure head is provided with a screwing arm or a hexagonal structure.
In another possible embodiment, the device further comprises a screwing rod, wherein the end of the force application section of the main rod is provided with a radial through hole, and the screwing rod penetrates through the radial through hole to drive the main rod to move.
In another possible embodiment, the screw shank is interference fitted with the radial through hole of the main shank.
In another possible embodiment, the outer diameter of the lower end of the ram is smaller than the outer diameter of the upper end of the nut to avoid interference with the upper end of the nut.
In another possible embodiment, two screw arms are provided outside the pressure head and are arranged circumferentially symmetrically.
The following detailed description is made with reference to the accompanying drawings:
as shown in fig. 1 to 4, an upper thread insert tooling includes a main rod 1, a screwing rod 2, a pressing head 3, and a screwing arm 4; the screwing rod 2 and the pressing head 3 are assembled on the main rod 1, and the screwing arm 4 is assembled on the pressing head 3. The main rod 1 is subjected to heat treatment to improve the hardness. And the threads and the lower end surface of the pressure head 3 are subjected to heat treatment to improve the hardness. The screwing rod 2 and the main rod 1 are in interference fit. The pressure head 3 and the screwing arm 4 are in interference fit. The lower end of the pressure head 3 cannot interfere with the upper end of the threaded sleeve. The pressure head 3 and the main rod 1 can realize relative movement through threaded rotation. The internal thread of the pressure head 3 is the same as the internal thread of the screw sleeve in specification.
The dimensions in the drawings are merely schematic illustrations and are not particularly limiting.
The working principle is as follows:
during with 1 lower extreme external screw thread screw in swivel nut internal thread of mobile jib, rotatory arm 4 of twisting drives pressure head 3 downstream until laminating with the swivel nut upper end, then rotatory arm 2 of twisting drives mobile jib 1, pressure head 3, a swivel nut syntropy assembly parts and removes, treats to screw up after the assembly is accomplished and twist arm 4 of twisting, reverse twisting mobile jib 1, with the same separation of pressure head 3 and swivel nut of mobile jib 1. The length of the external thread of the main rod 1 is longer than the sum of the lengths of the internal threads of the pressure head 3 and the screw sleeve. And after the screwing rod 2 and the screwing arm 4 are damaged, the screwing rod 2 and the screwing arm 4 can be replaced according to the main rod 1 and the corresponding inner hole diameter processing inner diameter of the pressure head 3. The tool material is steel.
Has the advantages that:
the new frock makes spacing part and the interior thread frock of screwing into the separator, and the reverse limit to the swivel nut has also been played through reverse afterburning spacing part when anti-intermediate peashrub dismantlement, has prevented that the swivel nut from droing. The situation that the threaded sleeves move together during disassembly is avoided, the reliability of assembly is guaranteed, and efficient and stable assembly is realized.
