Abstract
The utility model relates to a nut installing/disassembling tool of a diameter-expansion head. The tool comprises a nut; a support is installed on the outer circumferential face of the nut; two parallel ring-shaped structures extend from the bottom of the support in a spaced manner; the ring-shaped structure wraps the outer ring of the nut; an installing plate is installed on the upper part of the support; a clamp plate is fixed on the installing plate by a fastening piece; the bottom of the clamp plate is pressed against the outer ring of the nut; rolling bears are installed on the lower ends of the lower part of the ring-shaped structure by rotating shafts; and the nut is arranged on the rolling bearings. The tool is proper and compact in structure and easy to operate; by arranging a second long circular hole, positions of the clamp plate can be easily adjusted; and the nut is arranged on the rolling bearings, so the tool is easy and fast to use and highly safe and reliable during the installing and disassembling process of the nut.
Description
Technical field
The utility model relates to hole enlargement equipment technical field, especially a kind of expanding head nut installing/dismounting frock.
Background technology
At present, in hole enlargement equipment, expanding head is critical component in hole enlargement equipment.Hole enlargement frock configuration expanding head, its shared limited space, shape and embedding structure complexity, the fixing guarantee expanding head of hole enlargement frock is stressed evenly, expanding head is stressed is: by the directly radial motion of contact steel pipe modular walls of the axially-movable conversion of pull bar, reach the welding stress producing eliminate the briquetting pressure that produces of steel pipe and welding in forming process time, and ensure that steel pipe total length section diameter is basically identical.Expanding head, it comprises that multiple workpiece assemblies such as cone, voussoir, the T-shaped key of length, backing plate, module form, complete its assembling after directly pack on expanding machine.
In hole enlargement equipment, rod assembly is the critical component in hole enlargement equipment, and nut is equipped with respectively in rod assembly both sides, and every kind of nut has corresponding steel pipe specification.At steel pipe's production scene, the specification of steel pipe's production is not of uniform size, just need to frequently change, and nut also will often be changed thereupon.
Rod assembly of the prior art, comprise multiple workpiece such as pull bar, pull bar sleeve, front and back end nut, front and back end self-lubricating cover, centering flange, plane slide block, cambered surface slide block, backing roll and back shaft, front and back end nut in when assembling by suspender belt or the direct handling of steel wire rope and installation, dismounting, there is no special equipment, be inconvenient to install, dismantle, poor stability.
Utility model content
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of expanding head nut installing/dismounting frock rational in infrastructure, thereby effectively improves the security that nut uses in the time of handling and installation, dismounting, can install easily, dismantle nut.
The technical scheme that the utility model adopts is as follows:
A kind of expanding head nut installing/dismounting frock, comprise nut, on the outer circumference surface of described nut, support is installed, described frame bottom spacing distance is extended with two parallel cirque structures, described cirque structure wraps nut cylindrical, described support top is provided with installing plate, on described installing plate, is fixed with clamp by securing member, and the bottom of described clamp and nut cylindrical prop up; Be positioned at two ends, described cirque structure bottom and by rotating shaft, rolling bearing be installed respectively, described nut is positioned on rolling bearing.
Further improvement as technique scheme:
In the middle of support, the diameter of circular configuration is greater than the outer diameter of a circle of nut;
On described clamp, have the second slotted hole, described clamp is secured by bolts on installing plate;
On described installing plate, be horizontally arranged with the first slotted hole.
The beneficial effects of the utility model are as follows:
The utility model is rational in infrastructure, compact, easy to operate, by the design of the second slotted hole, can regulate easily clamp position, nut is positioned on rolling bearing, in the installation and removal process of nut, convenient to use, security is good, good reliability.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the side view of Fig. 1.
Wherein: 1, installing plate; 2, the first slotted hole; 3, support; 4, clamp; 5, bolt; 6, the second slotted hole; 7, nut; 8, rotating shaft; 9, rolling bearing.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As depicted in figs. 1 and 2, the expanding head nut installing/dismounting frock of the present embodiment, comprise nut 7, support 3 is installed on the outer circumference surface of nut 7, support 3 bottom interval distances are extended with two parallel cirque structures, and cirque structure wraps nut 7 cylindricals, and support 3 tops are provided with installing plate 1, on installing plate 1, be fixed with clamp 4 by securing member, the bottom of clamp 4 and nut 7 cylindricals prop up; Be positioned at two ends, cirque structure bottom and by rotating shaft 8, rolling bearing 9 be installed respectively, nut 7 is positioned on rolling bearing 9.
In the middle of support 3, the diameter of circular configuration is greater than the outer diameter of a circle of nut 7.
On clamp 4, have the second slotted hole 6, clamp 4 is fixed on installing plate 1 by bolt 5.
On installing plate 1, be horizontally arranged with the first slotted hole 2.The design of the first slotted hole 2, facilitates the lifting of frock.
In actual use procedure, due to the effect of the second slotted hole 6, can regulate easily the upper-lower position of clamp 4.First nut 7 is packed in the cirque structure of support 3, regulate the position of clamp 4, make it fix nut 7, in the time of handling, nut 7 just can double swerve, ensures its security.Due to the design of rolling bearing 9, totally four rolling bearings 9, it forms certain angle, and nut 7 is placed on rolling bearing 9, and in the time of installing/dismounting, clamp 4 unclamps, and nut 7 just can easily rotate, and so just can conveniently directly mount and dismount nut 7.Easy to use and reliable, cost is low.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of amendment.
