The specific embodiment
Below in conjunction with accompanying drawing, the embodiment of the present invention is described in detail.
Can't from the blind hole of the frock of assembly welding, remove the problem of tooling shaft for solving in prior art, the embodiment of the present invention provides a kind of provision for disengagement of blind hole tooling shaft, the blind hole tooling shaft is designed to hollow shaft 3, the blind hole tooling shaft is designed with screw thread 8 away from the endoporus place of an end 11 of blind hole, provision for disengagement comprises leading screw 1 and the sleeve assembly 2 for locating leading screw 1, the end 11 that the hollow shaft 3 that is set in sleeve assembly 2 exposes, utilize the threaded engagement of leading screw 1 and hollow shaft 3, just hollow shaft 3 can be taken apart from blind hole.
As shown in Figure 1, in embodiments of the present invention, the blind hole tooling shaft inside of positioning tool part is designed to hollow shape, is hollow shaft 3, described hollow shaft 3 external diameters can be Φ 65mm, the endoporus aperture can be Φ 42mm, the external diameter of end can be Φ 75mm, and hollow shaft 3 length can be 195mm, and the blind hole tooling shaft is designed to screw thread away from the endoporus place of an end 11 of blind hole, described screw thread is preferably rectangular thread 8, and described rectangular thread 8 degree of depth can be 40mm.Selecting rectangular thread, rather than select regular screw threads or trapezoidal thread, be because rectangular thread can bear larger active force, and recycling rate of waterused is high, processes easy.
As shown in Figure 2, in embodiments of the present invention, sleeve assembly 2 is formed by cut deal 4 and seamless steel pipe 5 assembly weldings, cut deal 4 external diameters are identical with seamless steel pipe 5 diameters, the centre-drilling hole of cut deal 4, and aperture is greater than leading screw 1 external diameter 0.8-1.2mm, preferred 1mm, seamless steel pipe 5 inwalls and hollow shaft 3 cylindricals keep the gap value of 1.5-2mm, produce friction with seamless steel pipe 5 inwalls when certain gap value can avoid rotating threaded shaft 1 to extract hollow shaft 3, the resistance that the reduction tooling shaft exits.During dismounting hollow shaft 3, for making its blind hole that breaks away from frock fully, the interior hole depth of seamless steel pipe 5 should be more than or equal to hollow shaft 3 length.
As shown in Figure 3, in embodiments of the present invention, leading screw 1 is selected the rectangular thread 7 with hollow shaft 3 same sizes, utilize the rectangular thread 7 of leading screw 1 to coordinate with the rectangular thread 8 of hollow shaft 3, by leading screw 1 is passed to sleeve assembly 2, screw in hollow shaft 3, the end 11 that the hollow shaft 3 that is set in sleeve assembly 2 exposes, when leading screw 1 passes the threaded engagement of sleeve assembly 2 hollow shafts 3, because the aperture of cut deal 4 is less than the external diameter of the end 6 of leading screw 1, the end 6 of leading screw 1 is positioned in cut deal 4 one sides, and can not move axially, therefore, along with leading screw 1 screws in hollow shaft 3, hollow shaft 3 is taken away the blind hole of frock.The external diameter of the end 6 of leading screw 1 can be Φ 60mm, and 6 places, leading screw 1 end can hole, and aperture can be Φ 17mm, so that rotational lead screw 1, reduces the dismounting difficulty, thus fast power-saving hollow shaft 3 is removed to the blind hole of frock.Preferably, can design the hole of two square crossings, certainly, can be also that determine according to specific needs ，Kong De position, plural hole.
Fig. 4 is the provision for disengagement structural representation in use of the blind hole tooling shaft of the embodiment of the present invention.As shown in Figure 4, utilize provision for disengagement tooling shaft to be removed to the process of blind hole of frock as follows: to need the assembly welding frock of hollow shaft 3 location after assembly welding, hollow shaft 3 is stuck while needing to take out in frock, sleeve assembly 2 is enclosed within to the end 11 that hollow shaft 3 exposes, now sleeve assembly 2 is positioned at the blind hole place, leading screw 1 is through cut deal 4 and seamless steel pipe 5, the end 6 of leading screw 1 props up cut deal 4, play the effect of location leading screw 1, now hollow shaft 3 is at hollow shaft removed position 9 places not, along with leading screw 1 slowly screws in hollow shaft 3, hollow shaft 3 is just taken away the blind hole of frock by leading screw 1, now hollow shaft 3 is in seamless steel pipe 5, 10 places, position after dismantling, leading screw is screwed out to hollow shaft 3 and sleeve assembly 2, take out hollow shaft 3, dismounting completes immediately.
The embodiment of the present invention also provides a kind of method for dismounting of blind hole tooling shaft.With reference to Fig. 5, described method for dismounting comprises the steps:
Wherein, the concrete structure of sleeve assembly 2, hollow shaft 3 and leading screw 1 and size relationship can be referring to mentioned above, and this repeats no more.
In sum, the present invention is designed to hollow shaft by the blind hole tooling shaft, and be designed with screw thread in hollow shaft away from the endoporus place of an end of blind hole, utilize the threaded engagement of leading screw and hollow shaft, the blind hole tooling shaft that can be fast simple will be stuck in the frock of welding deformation therefrom takes out, and while greatly reducing the frock assembly welding, the difficulty of tooling shaft dismounting, simplify processing step, raise labour efficiency, reduce production costs.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of making, be equal to replacement, improvement etc., within all should being included in the scope of protection of the invention.
