Abstract

The utility model discloses a wrench socket capable of restraining reaction torque. The wrench socket comprises a socket body, an inner core and a pin. The socket body is shaped like a hollow column, a first internal hexagon and a second internal hexagon are respectively arranged at two ends of the socket body, and a plurality of pin holes are arranged in the socket wall along the radial direction. The inner core is a cylinder provided with an internal square, a ring groove is arranged in the outer diameter of the inner core, and the inner core is arranged inside the hollow portion of the socket body. The pin is inserted between the pin holes of the socket body and the ring groove of the inner core. The wrench socket has the advantages of being simple in structure, convenient to use, high in work efficiency, safe and reliable.

Description

The wrench socket that suppresses reaction torque

Technical field

The utility model relates to the annex of machine tool technical field, especially a kind of wrench socket that suppresses reaction torque.

Background technology

Collars is the important spare part of high-speed rod-rolling mill in the steel and iron industry field, the installation of collars roughly has three kinds of frame modes, the one, be that the hydraulic pressure of representative compresses tapered sleeve tensioning mode with the root milling train that rubs, the 2nd, be that the hydraulic pressure of representative compresses tapered sleeve tensioning mode with the Da Nieni milling train, the 3rd, be the tensioning mode that the mechanical type nut of representative compresses tapered sleeve with other milling train.The technical program designs at the third collars mounting or dismounting mode, prior art is in the course of work of mounting or dismounting collars, tapered sleeve is installed or removed to hydraulic torque wrench or the aerodynamic moment spanners of adopting more, a urgent tapered sleeve is wanted nearly two minutes consuming time, the problem that exists is, owing to need bigger tensile force between collars locking nut and tapered sleeve, need adopt hydraulic torque wrench or aerodynamic moment spanner to apply a moment of torsion to nut during mounting or dismounting, the collars locking nut can produce a reaction torque to torque wrench, this reaction torque is applied to the operator by torque wrench, will there be potential safety hazard in misoperation; For ensureing handling safety, must reach the pretightning force that nut compresses tapered sleeve again, the operation that the operator must take progressively to increase moment of torsion, multi-pass operation is installed tapered sleeve, causes inefficiency.

The utility model content

The purpose of this utility model is a kind of wrench socket that suppresses reaction torque that provides at the deficiencies in the prior art, the utlity model has simple in structure, easy to use, high efficiency and safe and reliable advantage.

The concrete technical scheme that realizes the utility model purpose is:

A kind of wrench socket that suppresses reaction torque, its characteristics comprise sleeve body, inner core and pin, and described sleeve body is open column shape, and its two ends are respectively equipped with six sides and second interior six sides in first, barrel radially is provided with several pin-and-holes, inner core is the cylinder of side in being provided with, and its external diameter is provided with annular groove; Described inner core is located in sleeve body hollow, and pin is inserted between the annular groove of the pin-and-hole of sleeve body and inner core.

The utlity model has simple in structure, easy to use, high efficiency and safe and reliable advantage.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the side view of Fig. 1;

Fig. 3 is use view of the present utility model.

The specific embodiment

Consult Fig. 1, Fig. 2, the utility model comprises sleeve body 1, inner core 2 and pin 3, described sleeve body 1 is open column shape, its two ends are respectively equipped with six sides 11 and second interior six sides 13 in first, barrel radially is provided with several pin-and-holes 12, inner core 2 is the cylinder of side 22 in being provided with, and its external diameter is provided with annular groove 21; Described inner core 2 is located in sleeve body 1 hollow, and pin 3 is inserted between the annular groove 21 of the pin-and-hole 12 of sleeve body 1 and inner core 2.

The scope of application of the present utility model:

Roll 4 terminations that the utility model was suitable for are provided with roll square toes 41, and collars locking nut 42 and roll 4 engagements, aerodynamic moment spanner 5 are that six square toes 51 drive, and the center is provided with wrench square head 52.

Connection of the present utility model:

Consult Fig. 1, Fig. 3, during work, with the utility model cylindrical shell 1 first in six sides 11 be enclosed within on the collars locking nut 42, ends of side 22 are sleeved on the roll square toes 41 in the inner core 2, with six square toes 51 of aerodynamic moment spanner 5 be enclosed within cylindrical shell 1 second in six sides 13, wrench square head 52 is inserted in inner core 2 interior square 22 the other ends.

The utility model is work like this:

When installation or dismounting collars locking nut 42, select turning to of aerodynamic moment spanner 5, start aerodynamic moment spanner 5, the output torque of aerodynamic moment spanner 5 drives cylindrical shell 1 by six square toes 51, first interior six sides, the 11 driven roller ring lock jack panels 42 of cylindrical shell 1 rotate, the pin 3 that is inserted into cylindrical shell 1 moves with respect to the annular groove 21 of inner core 2, and inner core 2 does not rotate, simultaneously, the reaction torque that collars locking nut 42 produces is applied on the aerodynamic moment spanner 5 by cylindrical shell 1, and by wrench square head 52, inner core 2 is passed on the roll square toes 41, this reaction torque is by 41 restrictions of roll square toes, can not be applied to the operator on hand by aerodynamic moment spanner 5, eliminated the potential safety hazard that the operator exists in installing or remove collars locking nut 42 processes.

For guaranteeing to reach the pretightning force of collars locking nut 42, only need to adjust the output torque of aerodynamic moment spanner 5, the operator can finish installation or the dismounting work of collars locking nut 42 fast, efficiently.
