Specific implementation mode
It is described below for disclosing the utility model so that those skilled in the art can realize the utility model.It retouches below
Preferred embodiment in stating is only used as illustrating, it may occur to persons skilled in the art that other obvious modifications.
As shown in Figure 1 to Figure 2 is a kind of torsion tooth attacking device 1, and the torsion tooth attacking device 1 includes ontology 10 and adjusting structure
Part 20, the ontology 10 are equipped with accommodating chamber 101, and plug is equipped in the accommodating chamber 101 of the ontology 10 and is screwed 11, spring base
12, the first spring 13, second spring 15 and pedestal 16, the plug, which screws, 11 to be axially set in the accommodating chamber 101, institute
The upside that spring base 12 is set to the accommodating chamber 101 is stated, the pedestal 16 is set to the lower section of the accommodating chamber 101, described
First spring 13 connects the plug and screws 11 and the spring base 12, pedestal 16 described in 15 elastic connection of the second spring
The lower surface of upper surface and the spring base 12, it is described plug screw 11 lower end be equipped with screw tap sets of holes 12, be able to installation screw tap
Set, the adjustment means 20 are adjustably coupled to the downside of the ontology 10.To by the size for changing spring, increase and turn round
Power makes to be not easy to skid when tapping, to improve machined surface quality, reduces process time, promotes processing efficiency.
The line footpath of the second spring 15 is more than the line footpath of first spring 13, and be increased the pedestal 16 and described
Spring torsion between spring base 12.
The ontology 10 is further fitted with mandrel 14, and the accommodating chamber 101 is formed in the mandrel 14, the mandrel
14 outside offers cone slot 141, and the cone slot 141 is the structure of falling Figure of eight, and the cone slot 141 is directed at eight words that fall of wire taper sleeve
Slot.
The adjustment means 20 include that collet cutting ferrule 21 and limit steel ball 23, the collet cutting ferrule 21 are connected to the core
The outside of axis 14, the collet cutting ferrule 21 are equipped with limiting section 22, and the limiting section 22 is from the collet cutting ferrule 21 to the cone slot
141 arcs protrude, and the limit steel ball 23 is set between the cone slot 141 and the collet cutting ferrule 21.When the collet card
When the limiting section 22 of set 21 is towards the cone slot 141, the limit steel ball 23 is pushed into the cone slot 141 so that radial direction side
To become large-sized, the second spring 15 is compacted；When the limiting section 22 of the collet cutting ferrule 21 deviates the cone slot 141
When, the limit steel ball 23 is displaced outwardly so that the size of radial method becomes smaller.
Wherein, the ontology 10 is further fitted with sheath 17, positioning pin 18 and positioning ball 19, and the sheath 17 is set
It is placed in the outside of the ontology 10, the positioning pin 18 is installed between the mandrel 14 and the sheath 17, the positioning steel
