Specific embodiment
With reference to the accompanying drawing, a specific embodiment of the utility model is described in detail, it is to be understood that this
The protection scope of utility model is not limited by the specific implementation.It is to be appreciated that the following implementation of the utility model
On the basis of position when stick vertical display is all dismantled by set pin sleeve in "upper", "lower" direction mentioned in mode.These are used to
The word in limitation direction is intended merely to facilitate explanation, does not represent the limitation to the utility model specific technical solution.Unless
It illustrates, components representated by identical label are the components of same structure in appended drawing reference.
A kind of tool for tearing set pin sleeve, drill bushing open as shown in the picture, including set pin sleeve dismantle stick 1, support plate 2, pin shaft
3, spring 4；It is upper and lower two pieces that the support plate 2, which is divided to, and structure is identical；As shown in Figure 8 and Figure 9: support plate 2 is provided centrally with
One guide hole 23 in order to which set pin sleeve disassembly stick 1 passes through support plate 2, and realizes that set pin sleeve dismantles stick 1 by the guide hole 23
Move up and down；The deep gouge 22 of one with 23 concentric of guide hole are additionally provided in support plate 2.Support plate 2 close to edge also
Pin shaft hole 21 there are three distribution triangular in shape is set.The upper and lower support plate 2 is sold with three vertically respectively by pin shaft hole 21
The upper and lower end of axis 3 closely connects, and constitutes the overhead support frame in inside, this close connection type can be between axis, hole
Interference fit, can also by pin shaft 3 pass through pin shaft hole 21 after be fixed again with other fasteners, for convenience of dismount, the pin shaft 3
It can be replaced with bolt or stud.As shown in Fig. 5,6 and 7: it is provided with a flange 13 in the middle part of the set pin sleeve disassembly stick 1, under
Portion is provided with an inner cavity 12 adaptable with the size of positioning pin 5, and top is provided with a diameter less than the intracavity diameter
And the long through-hole being connected to inner cavity；A positioning pin poke rod recessing groove 11 is provided on the side wall of the inner cavity 12, this is fixed
Position pin poke rod recessing groove 11 is " U "-shaped, so as in set pin sleeve disassembly process, to positioning pin poke rod 6 or other machinery
Connector, which is realized, steps down.The flange 13 at 1 middle part of set pin sleeve disassembly stick is in the inside of support frame as described above, and set pin sleeve is torn open
Unloading 1 lower part of stick has in the center guide hole 23 of sub-fraction insertion lower supporting plate 2, ensure that the stability of tool；The positioning pin
Set disassembly 1 lower part of stick passes through the spring 4, and the following table of set pin sleeve disassembly 1 intermediate flange 13 of stick is pressed in the upper end of spring 4
The lower end in face, spring 4 is embedded in deep gouge 22 and presses the lower supporting plate 2；Under the action of spring 4, so that described fixed
The flange 13 at 1 middle part of position guide disassembly stick is also embedded in the deep gouge 22 of upper backup pad 2, since support plate 2 and set pin sleeve are dismantled
The interaction of 1 intermediate flange 13 of stick, so that set pin sleeve dismantles stick 1 in the support frame that the support plate 2 and pin shaft 3 form
It moves up and down without departing from support frame.
Set pin sleeve described in the utility model dismantles the outer diameter of stick lower part between 8 internal diameter of lathe location hole and positioning
Between guide 7 or drill bushing outer diameter；The intracavity diameter of the set pin sleeve disassembly 1 lower part of stick is greater than 5 outer diameter of positioning pin.In this way
Design on the one hand both guaranteed be not in use tear set pin sleeve open, the tool of drill bushing can not knock in lathe location hole 5,
And the inner cavity 12 of set pin sleeve disassembly 1 lower part of stick cannot be inserted in the appearance of this kind of situation of positioning pin 5, so that positioning pin can not be dismantled
Set or drill bushing.On the other hand the case where being then after the completion of considering disassembly, as shown in figure 12: after set pin sleeve 7 is separated lathe,
Since the outer diameter of set pin sleeve disassembly stick lower part is less than 8 internal diameter of lathe location hole, positioning pin thus will can be easily torn very much open
It covers, the tool of drill bushing detaches lathe；After being detached from the extruding of positioning pin poke rod 6, positioning pin 5 also can be toward falling, to complete entire
Disassembly process.But also after set pin sleeve 7 separates lathe, set pin sleeve disassembly stick lower part can take out automatically for the use of spring 4
It disembarks a location hole 8, to reduce the take-down time.When positioning pin 5 be stuck in set pin sleeve disassembly stick lower lumen 12 in cannot be real
When now falling down automatically, the long through-hole on set pin sleeve disassembly stick top can be passed through with an elongated rods, by positioning pin 5 from inner cavity
It is knocked out in 12.As shown in Figure 10,11 and 12: in disassembly process, needing the center guide hole 23 of support base 2 and lathe location hole 8
It is corresponding, set pin sleeve disassembly stick 1 is driven in lathe location hole 8 with facilitating, is then tapped on set pin sleeve disassembly stick 1 with hammer
The upper surface in portion, can also guide disassembly in place 1 top of stick pneumatic shuttle is installed, make the lower part of set pin sleeve disassembly stick 1 steadily into
Enter in lathe location hole 8, and set pin sleeve or drill bushing are then separated from lathe location hole 8.It should be noted that " u "-shaped in disassembly process
The position of positioning pin poke rod recessing groove 11, so as in set pin sleeve disassembly process, to positioning pin poke rod 6 or other machinery
Connector, which is realized, steps down, to avoid the damage of components.
