The specific embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described in detail.
For solving in prior art, cannot from the blind hole of the frock of assembly welding, remove the problem of tooling shaft, the utility model embodiment provides a kind of provision for disengagement of blind hole tooling shaft, blind hole tooling shaft is designed to hollow shaft 3, blind hole tooling shaft is designed with screw thread 8 away from the endoporus place of one end 11 of blind hole, provision for disengagement comprises leading screw 1 and for locating the sleeve assembly 2 of leading screw 1, one end 11 that the hollow shaft 3 that is set in sleeve assembly 2 exposes, the threaded engagement of utilizing leading screw 1 and hollow shaft 3 just can take apart hollow shaft 3 from blind hole.
As shown in Figure 1, in the utility model embodiment, 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, endoporus aperture can be Φ 42mm, the external diameter of end can be Φ 75mm, and hollow shaft 3 length can be 195mm, and blind hole tooling shaft is designed to screw thread away from the endoporus place of one 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 the utility model embodiment, 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, the resistance that reduction tooling shaft exits when certain gap value can avoid rotating threaded shaft 1 to extract hollow shaft 3 with seamless steel pipe 5 inwalls.During dismounting hollow shaft 3, for making its blind hole that departs from frock completely, 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 the utility model embodiment, leading screw 1 is selected the rectangular thread 7 with hollow shaft 3 same sizes, utilize the rectangular thread 7 of leading screw 1 and the rectangular thread 8 of hollow shaft 3 to coordinate, by leading screw 1 is passed to sleeve assembly 2, screw in hollow shaft 3, one 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 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 position, plural hole.
Fig. 4 is the structural representation in use of provision for disengagement of the blind hole tooling shaft of the utility model embodiment.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 one end 11 that hollow shaft 3 exposes, now sleeve assembly 2 is positioned at 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 utility model embodiment 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 utility model is designed to hollow shaft by blind hole tooling shaft, and away from the endoporus place of one end of blind hole, be designed with screw thread in hollow shaft, utilize the threaded engagement of leading screw and hollow shaft, can be fast simple the blind hole tooling shaft being stuck in the frock of welding deformation be therefrom taken out, while greatly reducing frock assembly welding, the difficulty of tooling shaft dismounting, simplifies processing step, raise labour efficiency, reduce production costs.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in the scope of the utility model protection.
