Description
Technical field
The utility model belongs to assembly field more particularly to a kind of contact switching device for pin removal.
Background technology
It is being assembled, in maintenance work, positioning pin frequently makes as part indispensable in cooperation, assembling process
With, and positioning pin needs to use " pin removal " this specific purpose tool during choosing.Before this, maintenance department can all be equipped with a set of
The pin pulling head of pin removal, the pin removal is non-standard component, is made of a threaded screw rod of double end, screw rod one end is fixed
M16 screw threads, the other end be then fabricated to according to actual needs M3 M4 the screw threads such as M5, in actual job, since burn into rust is waited indefinitely
Phenomena such as factor, positioning pin is very tight, and thinner screw thread is susceptible to fracture, bending, sleave leads to that operation cannot be continued, and needs
Pin pulling head is re-worked.It seriously affects job scheduling, expend processing charges.
Invention content
The purpose of this utility model is to provide a kind of contact switching device for pin removal, solves and existing pull out rising
When, it since positioning pin is very tight, rises and pulls out phenomena such as screw is susceptible to fracture, bending, sleave, lead to that operation cannot be continued, need
Pin pulling head is re-worked, to seriously affect the defect of job scheduling.
In order to achieve the above object, the technological means of the utility model use is：
A kind of contact switching device for pin removal provided by the utility model, including contact switching device ontology, connect
One end of head conversion equipment ontology is flexibly connected with the bar of pulling pin of pin removal；The other end of contact switching device ontology is flexibly connected
It has been useful for sub screw of pulling pin.
Preferably, one end of contact switching device ontology offers threaded hole, the double end of the threaded hole cooperation pin removal
Connecting screw is connect with bar of pulling pin；The other end of contact switching device ontology offers the mounting hole for screw to be arranged.
Preferably, it is communicated between threaded hole and through-hole, and the diameter of threaded hole is more than the diameter of through-hole.
Preferably, one end of screw is matched with pin；The other end is installed on the step surface between through-hole and threaded hole.
Preferably, it pulls pin and is set with weight on bar.
Preferably, it is slidably connected between weight and bar of pulling pin.
Compared with prior art, the utility model has the beneficial effects that：
A kind of contact switching device for pin removal provided by the utility model selects phase according to the model of pin first
Screw, is then screwed into pin by matched contact switching device ontology, then screw is installed to contact switching device ontology
It is interior, pin is extracted finally by pin removal；Due to being flexibly connected for pin removal and contact switching device, can be adapted for
The pin of different model rises and pulls out；It due to being flexibly connected for screw and contact switching device, solves screw when being broken, needs
The problem of pin pulling head being re-worked；The structure meets the requirement of job scheduling；The present apparatus is enterprising in original pin removal
Row Optimal improvements are simple in structure, practical；And material selection metal material processing forms, and it is durable, it is hardly damaged.In addition, this
Converter device largely saves maintenance cost, and original pin removal connector belongs to shop parts, once in operation of pulling pin
There is phenomenon of rupture, need to carry out from new processing, time-consuming effort.And pin pulling head can be converted to common screw by the present apparatus, one
But pin pulling head fractures, and only needs to change a screw；
This switching device is simple in structure, conversion is convenient, cost is extremely low, it is most important that do not interfere with assembly, repair into
Degree, using effect are preferable.The switching device has extensive usability, can plain screw be converted into pin pulling head, for choosing
Positioning pin with threaded hole.
Description of the drawings
Fig. 1 is the sectional view of contact switching device；
Fig. 2 is the vertical view of contact switching device；
Fig. 3 is the installation diagram of pin removal；
Wherein, 1, contact switching device ontology 2, bar 3 of pulling pin, weight 4, connecting screw 5, screw 101, threaded hole
102, mounting hole.
Specific implementation mode
Below in conjunction with the accompanying drawings, the utility model is further described.
As shown in Figure 1 and Figure 2, a kind of contact switching device for pin removal provided by the utility model, including connector turn
One end of changing device ontology 1, the contact switching device ontology 1 offers threaded hole 101；The other end offers mounting hole 102.
The threaded hole 101 is connected with the connecting screw on pin removal；Cooperation is equipped with spiral shell in the mounting hole 102
Nail；Screw and 1 detachable connection of contact switching device ontology.
Embodiment
As shown in figure 3, Special pin puller includes pulling pin bar 2, weight 3 and connecting screw 4, wherein pull pin bar 2 with connect spiral shell
One end of bar 4 connects；The other end of connecting screw 4 is connected with contact switching device ontology 1, and weight 3 is sleeved on connecting screw 4
On.
Specifically, the threaded hole 101 opened up on connecting screw 4 and contact switching device ontology 1 is connected, connector conversion
Screw 5 is connected on device body 1.
It is communicated between threaded hole 101 and through-hole 102, and the diameter of threaded hole 101 is more than the diameter of through-hole 102.
Screw 5 is passed into out of threaded hole 101 in through-hole 102 when mounted, by one end of screw 5, and screw 5 is upper
End is stuck on the step surface between through-hole 102 and threaded hole 101.
When in use：
First, with the diameter for the pin pulled pin, the identical contact switching device of size is selected.
By taking the pin for M3 threaded interior holes of choosing as an example, first, a M3 screw 5 is found, screw 5 is put into through-hole 102；
Then, screw 5 is screwed in pin to be chosen with spanner；Then, will pull pin bar 2, weight 3 pass through connecting screw 4 with switching
In the connection of device body 1, meanwhile, 4 housing screw 5 of connecting screw prevents the loosening of screw 5；Finally, by moving back and forth weight
3, realize operation of pulling pin by the inertial impact force of weight 3.
In the process, once there is the fracture of screw 5, buckling phenomenon, contact switching device ontology 1 only need to be dismantled, more
Change a new screw 5.
