Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Embodiment 1
The present invention provides a kind of full-floating type round nut assembling and disassembling device, for steel pipe drawing machine upper mold positioning round nut
Automatic assembly and disassembly, it is main comprising with lower component: swivel head 4, bayonet lock 3, floating disc 5, housing screw 9, round end ejector pin 8.The device can
Corresponding swivel head 4 is customized according to the specific size of nut, realizes the Fast Installation and disassembly of large-scale round nut.Specific such as Fig. 1
With shown in Fig. 2.
A kind of full-floating type round nut assembling and disassembling device, including swivel head 4, bayonet lock 3 and floating disc 5, wherein swivel head 4 is
The circular weld part of indent, the round nut outer diameter design that groove internal diameter can be assembled and disassembled as needed.
Six groups of bayonet locks 3 are evenly arranged on the circumferential cell wall of swivel head 4, bayonet lock 3 is fixed through cell wall, and every group two
It is a, to block six card slots of round nut, and round nut is driven to rotate, bayonet lock 3 can upper and lower retractable floating.
Wherein floating disc 5 is fixed by the housing screw 9 for being located at 4 bottom portion of groove center of swivel head, installs on housing screw 9
There are the first small butterfly spring and circular washer, circular washer and small butterfly spring are sequentially located between 9 head of a nail of housing screw and floating disc 5, thus
Floating disc 5 can be allowed to have certain deflection amount of floating while compressing floating disc 5.It is being rotated centered on housing screw 9
First 4 bottom wall is evenly provided with six round end ejector pins 8 along contour direction, and round end ejector pin 8 is shifted to install with bayonet lock 3, round end
Ejector pin 8 is in close contact through 4 bottom wall of swivel head and with floating disc 5, when in use due to housing screw 9 and round end ejector pin
8 pairs of floating discs 5 are float design, therefore there are decentractions for permission round nut and screw rod, and round nut is facilitated to screw in screw rod.
Swivel head 4 is directed at band installation round nut in use by apparatus of the present invention, and bayonet lock 3 blocks round nut card slot,
Floating disc 5 withstands the end face of round nut, realizes floating disc 5 automatically under the action of present apparatus housing screw 9 and round end ejector pin 8
Then stress balance rotates swivel head 4, round nut is selected into screw rod under the action of bayonet lock 3, and round nut is installed in place.
It is reversed to twist swivel head 4 after swivel head 4 is caught in round nut to be removed during dismantling round nut by the present apparatus,
Bayonet lock 3 blocks round nut card slot automatically, applies torque to nut, round nut is unclamped, until completing to dismantle.
Embodiment 2
On the basis of embodiment 1, as shown in Figure 1, present apparatus bayonet lock 3 is by big adjusting nut 1, pin and 2 groups of big disc spring
At wherein big adjusting nut 1 and big disc spring 2 are fixed by bolts on 4 side wall of swivel head, pin is located at the bottom of big disc spring 2
And protrude into 4 groove of swivel head, the tip that pin is contacted with assembly and disassembly round nut is two inclined-planes, and the longitudinal section at tip is obtuse angle
Triangle, bayonet lock 3 can upper and lower retractable floating, and provide elastic force by big disc spring 2, the size of elastic force can pass through the big adjusting nut of rotation
1 is adjusted, and the site of action of pin is designed as two inclined-planes in bayonet lock 3, when tightening nut, the big face contact circle of gradient
Nut card slot can skid off automatically card slot when round nut pretightning force reaches certain value；When unclamping round nut, since round nut exists
There may be additional axial loads in use process, and screw-down torque originally possibly can not unclamp round nut, therefore unclamp circle spiral shell
The small face contact round nut card slot of gradient, can not only provide enough release torque, but also will not be because of nut card in this way when female
Dead bayonet lock 3 can not skid off card slot and destroy equipment.
Round end ejector pin 8 is fixed on 4 bottom of swivel head by small adjusting nut 7 in the present apparatus, 8 head of a nail of round end ejector pin with it is small

Sample can allow floating disc 5 to have certain deflection amount of floating while compressing floating disc 5, and the floating power of floating disc 5 is by justifying
Small disc spring after crown pin 8 provides, and floating power can be realized by rotating small adjusting nut 7.
Embodiment 3
On the basis of the above embodiments, this round nut assembling and disassembling device installation nut the course of work be, will be on swivel head 4
Bayonet lock 3 according to nut groove position alignment sleeve loaded on round nut, at this point, big disc spring 2 under the compressing of pin adjust automatically by
Dynamic balance, so that the card slot of pin and round nut is in close contact, the big adjustment of screw-down torque appropriate adjustment according to required for round nut
Nut 1 guarantees that bayonet lock 3 keeps enough pressure to round nut.Floating disc 5 is withstood in the end face of round nut simultaneously, floating disc 5 by
The the first small butterfly spring and the second small butterfly spring installed on the pressure of round nut, housing screw 9 and round end ejector pin 8 are pushed in stress condition
It is reduced to stabilization, guarantees that floating disc 5 is close to the end face of round nut always, avoids generating nut and spiral shell during tightening round nut
Offset between bolt then rotates clockwise swivel head 4, and round nut just screws in screw rod, this process is because of bayonet lock 3 and floating disc 5
Be float design, therefore allow round nut and screw rod there are decentractions, round nut is facilitated to screw in screw rod, when round nut in place after
Torque increases, and when setting value beyond bayonet lock 3, bayonet lock 3 will skid off round nut card slot automatically, and round nut is installed in place.
The course of work of this round nut assembling and disassembling device disassembly nut are as follows: the round nut for needing to unclamp by the insertion of swivel head 4, card
Pin 3 enters the card slot of nut, and floating disc 5 withstands the end face of nut, rotates counterclockwise swivel head 4, big disc spring 2 and first, second
Small butterfly spring free extension under the action of nut stress, the relative position balance between adjusting nut and screw rod, sells in disassembly
The small face contact round nut card slot of gradient is followed closely, bayonet lock 3 enters in round nut card slot, applies torque to nut, by round nut pine
It opens, until completing to dismantle.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
