Technical field
This utility model is related to a kind of bolt and in particular to a kind of hydraulic pressure device for screwing up 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 carrying through hole.This type of attachment claims bolt connection.As nut is screwed off from bolt, this two can be made again
Part separates, therefore bolt connection is belonging to be detachably connected.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 the place that smooth surface after requiring to connect there is not projection, because countersunk head can
To be screwed in part；Round end can also be screwed in part, and the screwing force of square toes can more greatly, but size is very big.
The hydraulic pressure device for screwing up of conventional bolt assembly, typically as shown in figure 4, including being provided with the tightening machine of stator and rotor
Body, it is symmetrically set in and tightens two handles of body both sides, the set being connected with rotor located at two hydraulic oil pipes tightening body one end
The rotation tappet head that cylinder is detachably connected with sleeve, during work, rotation tappet head or sleeve is socketed on nut, or will
Sleeve is socketed on bolt head, and rotor drives tappet head or sleeve to rotate, and then nut is fixed on screw rod, thus realizing several
Connection between individual part.However, because sleeve, rotation tappet head are all to be connected with rotor, in the case that therefore rotor rotates,
Sleeve, rotation tappet head also and then rotate, and therefore traditional bolt hydraulic pressure device for screwing up is only applicable to plain bolt, for screw thread
The bolt being configured with the special construction of threaded end on bar cannot use, and range limits, poor practicability.Additionally, in spiral shell
In bolt rundown process, due to stress, inevitably the phenomenons such as skid or rocking occurs in threaded rod in nuts and bolt head, with
As for must need to fix nut or bolt head in advance, that is, the fastening of bolt to be realized, need simultaneously solid in bolt one end
The fixed, other end is tightened.If the part area connecting is big, thickness is thick, the length of threaded rod is longer, and a people just cannot grasp
Make, need two people to work simultaneously, waste time and energy and high labor intensive, especially producing in enormous quantities needs bolt parts
Factory, not only production efficiency is low, and cost of human resources is high simultaneously.
