Description
Technical field
The present invention relates to a kind of bolt, be specifically related to the hydraulic pressure device for screwing up of a kind of bolt.
Background technology
Bolt is widely used machine components, including bolt head and threaded rod, needs and nut screw connection, is used for being fastenedly connected
Two parts with through hole.This type of attachment claims bolt to connect.As nut is screwed off from bolt, the two can be made again
Part separates, therefore bolt connection is belonging to removably connect.Bolt head has turret head, round end, square spigot, countersunk head etc.
Deng, wherein turret head is the most frequently used.General countersunk head is used in requirement and connects the smooth place not having projection, rear surface, because countersunk head can
To be screwed in part；Round end can also be screwed in part, the screwing force of square toes can more greatly, but size is the biggest.
The hydraulic pressure device for screwing up of conventional bolt assembly, the most as shown in Figure 4, including the tightening machine being provided with stator and rotor
Body, it is symmetrically set in and tightens two handles of body both sides, be located at and tighten the set that two hydraulic oil pipes of body one end are connected with rotor
The rotation tappet head that cylinder removably connects with sleeve, during work, is socketed in rotation tappet head or sleeve on nut, or will
Sleeve is socketed on bolt head, and rotor drives tappet head or sleeve to rotate, and then is fixed on screw rod by nut, thus realizes several
Connection between individual parts.But, owing to sleeve, rotation tappet head are all to connect with rotor, in the case of therefore rotor rotates,
Sleeve, rotation tappet head also and then rotate, and the most traditional bolt hydraulic pressure device for screwing up is only applicable to plain bolt, for screw thread
The bolt of the special construction being configured with threaded end on bar cannot use, and range limits, poor practicability.Additionally, at spiral shell
In bolt rundown process, due to stress, nuts and bolt head inevitably occurs that phenomenons such as rocking occur in skidding or threaded rod, with
As for needing nut or bolt head to be fixed in advance, the fastening of bolt to be realized, need simultaneously solid in bolt one end
Fixed, the other end is tightened.If the parts area connected is big, thickness is thick, then the length of threaded rod is longer, and a people just cannot grasp
Making, need two people to work simultaneously, waste time and energy and labor intensity is big, especially producing in enormous quantities needs bolt parts
Factory, not only production efficiency is low, and cost of human resources is high simultaneously.
Summary of the invention
The deficiency existed for prior art, the present invention provides the hydraulic pressure device for screwing up of a kind of bolt, and this hydraulic pressure is tightened
The sleeve being connected with stator is set, changes the structure that tradition is connected with rotor, thus sleeve is not followed the rotation of rotor and rotated,
And the hollow rotation tightening piece and telescopic rotation tappet head being connected with rotor is set, make device for screwing up not only be suitable for common spiral shell
Tightening of bolt, is also applied for being threaded tightening of termination special bolts structure, and applied widely, practicality is good.
In order to achieve the above object, the technical scheme that the present invention takes:
A kind of hydraulic pressure device for screwing up of bolt, including tightening body, described in tighten body and include tightening shell and tightening
The integrated stator of the shell rotor that be connected supporting with stator, described in tighten two handles that are symmetrically arranged on two with of body, described
The one end tightening body is provided with two hydraulic oil pipes, the other end is provided with and tightens parts, described in tighten what parts included being connected with stator
Sleeve, the port of described sleeve offers the groove socket of hexagonal structure, and this groove socket can be sheathed on termination spiral shell
On the nut of the supporting connection of bolt, in described sleeve, also it is arranged with the hollow rotation tightening piece being connected and in hexa-prism with rotor,
The port of described hollow rotation tightening piece is removably connected with the rotation tappet head of the scalable setting of length, this rotation tappet head
The hexagonal structure of port, or offer on it groove of hexagonal structure or be provided with raise up in in-line, cross
Boss.
As optimal technical scheme, in order to change the drawback that conventional bolt one end is fixed, the other end is tightened, by tightening work
Tool just can realize the fastening of bolt the most rapidly in threaded rod one end, time saving and energy saving, is conducive to improving production and work efficiency,
Reducing cost of human resources, described head bolts includes that bolt head, the threaded rod being connected with bolt head are connected with shaft
Nut, the end outer surface of described threaded rod is arranged with the threaded end being connected with it, and described threaded end is six limits
Hexagonal, the groove of in-line, decussate texture is offered in shape structure, or described threaded end.
As optimal technical scheme, in order to ensure to rotate the stable connection between tappet head and hollow rotation tightening piece, anti-
Rotate coming off of tappet head during locking apparatus work, thus impact is tightened work and carried out in order, the end of described hollow rotation tightening piece
Mouthful carry out adding magnetic treatment, and described rotation tappet head is made up of magnetic material.
As optimal technical scheme, in order to make handle can fit tightly with finger, when reducing device work, handle is to hands
Referring to bring the senses of discomfort such as tenderness, thus be conducive to improving the steadiness between threaded rod and nut, described handle is provided with some
Individual curved shape hold groove.
Compared with prior art, the invention have the benefit that
1, the sleeve being connected with stator is set, changes the structure that tradition is connected with rotor, thus rotor do not followed by sleeve
Rotate and rotate, and the hollow rotation tightening piece and telescopic rotation tappet head being connected with rotor is set, make device for screwing up not
Only it is suitable for tightening of plain bolt, is also applied for being threaded tightening of termination special bolts structure, applied widely, practicality
Good.
2, being provided with the head bolts of threaded end, groove socket is socketed on nut, rotates the port of tappet head
It is socketed in threaded end, needs one end to fix when changing conventional hydraulic device for screwing up fastening bolt, drawback that the other end is tightened, pass through
The hollow rotation tightening piece on nut can be acted on by high pulling torque, just can realize the tight of bolt in threaded rod one end the most rapidly
Gu, time saving and energy saving, be conducive to improving production and work efficiency, reduce cost of human resources, convenient and practical, it is adaptable to multiple field
Close.
3, the port of hollow rotation tightening piece carries out adding magnetic treatment, rotates what tappet head was made up of magnetic material, it is ensured that
Rotate the stable connection between tappet head and hollow rotation tightening piece, during the work of anti-locking apparatus, rotate coming off of tappet head, it is ensured that
Tighten work to carry out in order.
What 4, handle was provided with several curved shapes holds groove, makes handle can fit tightly with finger, reduces dress
When putting work, handle brings the senses of discomfort such as tenderness to finger, thus is conducive to improving the steadiness between threaded rod and nut, enters
And ensure stablizing between parts connection.
