The lower thread of hammer stem 7 connects, and blind rivet 13 passes through blind rivet clamping portion and 12 snap fits of helping pull a cart.Wherein, blind rivet clamping portion is T shape
Structure, the clamping portion that helps pull a cart are equipped with the card holding trough matched with blind rivet clamping portion.
Deep hole described in the embodiment of the present invention grabs the assembly method for unloading set tool certainly are as follows:
Lock tube pawl 2 is mounted in the installation cavity of hammer body 1 by positioning pin 15 first, while passing through the connection of spring 10 the
One, which receives pawl 201 and second, receives the bottom of pawl 202, receives stretching for pawl 202 by two first receipts pawls 201 of the limitation of spacer pin 11 and second
Exhibition state, then hammer body 1 is threadedly coupled with extension rod 3, then extension rod 3 is sleeved in connecting sleeve 5, and make to receive pawl
The hollow cavity of device 4 is set in the top of hammer body 1, then will help pull a cart and 12 be threadedly coupled with extension rod 3, by blind rivet 13 and 7 spiral shell of hammer stem
Line connection, will finally help pull a cart 12 and the clamping of blind rivet 13.
Deep hole described in the embodiment of the present invention grabs the application method for unloading set tool certainly are as follows:
As seen in figs. 5-6, when setting initial free state, the ellipse short shaft direction of 4 middle and lower part elliptical cavity 401 of pawl device is received
It is perpendicular with lock tube pawl 2.Lock tube Shou Zhao mechanism is operated, receiving pawl switch 6 by rotation makes to receive pawl device relative to the rotation of hypophysis 1 90
Degree, when ellipse short shaft direction is parallel with lock tube pawl 2, lock tube pawl 2 is retracted in hammer body 1, as Figure 7-8.Then it is pushed away under passing through
Receiving pawl switch 6 drives receipts pawl device 4 to move down relative to hypophysis 1, and lock tube pawl 2 is made to enter the top full circle cavity received in pawl device 4
In 402, pawl device 4 then will be received again return and turn 90 degrees parallel with lock tube pawl 2 to transverse direction, unload set tool at this time in wait grab
Set state makes hammer body 1 pass through guide sleeve 14, as shown in figs. 9-10 at this time.When hammer body 1 passes through guide sleeve 14, pawl device 4 is being received
Continue to promote after end face contact guide sleeve 14, until lock tube pawl 2 is detached from top full circle cavity 402, into lower part elliptical cavity
In 401, lock tube pawl 2 opens release at this time, guide sleeve 14 is caught, as depicted in figs. 11-12.Guide sleeve 14 is grabbed in lock tube pawl 2
After firmly, extraction mechanism is operated, block 8 is back and forth tapped upwards by percussion hammer 9 by guide sleeve 14 and takes lathe out of.When by unloading set work
After tool takes guide sleeve 14 out of lathe, will receive pawl device 4 and be rotated by 90 ° keeps ellipse short shaft direction parallel with lock tube pawl 2, unloads set at this time
Tool is in relaxation state, and lock tube pawl 2 is contracted in hammer body 1, and guide sleeve 14 is then exited hammer body 1, as illustrated in figs. 13-14,
It so can be realized once to grab the deep hole of guide sleeve 14 certainly and unload set operation.
In conclusion deep hole described in the embodiment of the present invention is from the set tool that unloads is grabbed, easy to operate, use process facilitates fast
The time for replacing guide sleeve can be shortened within 3 minutes, effectively improve labor efficiency, and operator need not enter by victory
It carries out unloading set inside lathe, ensure that the personal safety of operator, reduce labor intensity, while can ensure guide sleeve bottom outlet
It is not destroyed, and present invention production is simple, it is only necessary to which simple assembly can be completed, and promotional value is high.
Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
Present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: it still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features；
