With the development of automobile industry, requirement of the people to automotive quality is also gradually stepped up, but the lifting of quality needs
The accuracy of manufacture raising, in increasingly competitive automobile industry, how to improve the accuracy of manufacture of automobile, be engineers weight
The problem of point concern.
There are many project-welding nuts on automobile, some situation nuts are needed first to be welded to small rack, and then support is welded to again
On vehicle body sheet metal, welding support can be using nut bore positioning in this case.Alignment pin can be with after the completion of welding for convenience
Smoothly taken out from nut bore, the ratio nut bore that alignment pin diameter can be done is less than normal, it is inaccurate that this may result in nut position location, essence
Degree declines.It is this utility model proposes a kind of alignment pin, the external diameter of the alignment pin is adjustable, and reaching can be with nut bore continuously
Gap coordinates, while easily can be taken out from nut bore again.
The alignment pin 100 of the utility model embodiment is described in detail with reference to Fig. 1 to Fig. 2, the utility model
The alignment pin 100 of embodiment can be used for positioning welding nut 200, but not limited to this.
Dowel body 110 and multiple positioning sliding blocks can be included according to the alignment pin 100 of the utility model embodiment
120。
Wherein, pressure chamber 101 is provided with dowel body 110, multiple positioning sliding blocks 120 wear the outer of pressure chamber 101
Perisporium, and each the inner of positioning sliding block 120 is arranged in pressure chamber 101, the outer end of each positioning sliding block 120 is arranged on pressure
Outside chamber 101, specifically, the outer end of each positioning sliding block 120 is arranged on the outside of the periphery wall of pressure chamber 101.
When being full of high-pressure medium in pressure chamber 101, multiple positioning sliding blocks 120 can be under the pressure of high-pressure medium outwards
It is mobile, and then the outer end of positioning sliding block 120 can stop with the inwall of nut bore to realizing the accurate of alignment pin 100 and nut bore
Positioning；When the high-pressure medium in pressure chamber 101 is discharged simultaneously, multiple positioning sliding blocks 120 may be at free state or inside
Move, and then multiple positioning sliding blocks 120 will not occur only support with the inwall of nut bore, alignment pin 100 can be easily from nut
Depart from hole, lift the location efficiency of alignment pin 100.
According to the alignment pin 100 of the utility model embodiment, by setting pressure chamber 101 in dowel body 110, and
Multiple positioning sliding blocks 120 are set on the periphery wall of pressure chamber 101 so that positioned when high-pressure medium is full of in pressure chamber 101
Sliding block 120 can be displaced outwardly stopping to realizing the precise positioning of welded nut 200 with the inwall with nut bore；In pressure chamber 101
Positioning sliding block 120 is in free state or moved inward when interior high-pressure medium disappears, and then facilitates alignment pin 100 from nut bore
It is middle to depart from.
In some embodiments of the present utility model, as shown in Fig. 2 multiple positioning sliding blocks 120 are uniform and compartment of terrain is worn
The periphery wall of pressure chamber 101.Thus, when being full of high-pressure medium in pressure chamber 101, the inwall uniform force of nut bore, positioning
The stability that pin 100 works is improved.
In some embodiments of the present utility model, as shown in Fig. 2 being provided with multiple peaces on the periphery wall of pressure chamber 101
Hole is filled, positioning sliding block 120 includes retaining part 121 and Access Division 122, and wherein Access Division 122 is arranged in pressure chamber 101, only supported
Portion 121 is arranged on outside pressure chamber 101 through the free end of mounting hole and retaining part 121, and the external diameter of Access Division 122 is more than mounting hole
Aperture.
Thus, retaining part 121 can easily pass through mounting hole, and Access Division 122 cannot pass through mounting hole, Access Division
122 play position-limiting action, it is to avoid positioning sliding block 120 is overall when high-pressure medium is full of in pressure chamber 101 takes off all from mounting hole
From.
Preferably, sealing ring (not shown) can be set in mounting hole.Thus, retaining part 121 and mounting hole are improved
Sealing property, it is to avoid high-pressure medium flows out from the gap of retaining part 121 and mounting hole, it is ensured that have foot in pressure chamber 101
Enough pressure.
In some embodiments of the present utility model, as depicted in figs. 1 and 2, alignment pin 100 also includes multiple return springs
130, multiple return springs 130 are corresponded with multiple positioning sliding blocks 120, one end of each return spring 130 with it is corresponding fixed
The inner of position sliding block 120 is connected, and the other end of each return spring 130 is connected with dowel body 110.Thus, in pressure chamber
When high-pressure medium in 101 is discharged, return spring 130 can drive positioning sliding block 120 to move inward, and then alignment pin 100
External diameter is less than the internal diameter of nut bore, and alignment pin 100 easily can depart from from nut bore.
Specifically, as shown in Figure 1-2, alignment pin 100 also includes mounting rod 140, and mounting rod 140 is arranged on pressure chamber 101
Bottom wall on, the inner of described one end of each return spring 130 and corresponding positioning sliding block 120 is connected, each return spring
130 other end is connected with mounting rod 140.Mounting rod 140 can be arranged on the centre position of the bottom wall of pressure chamber 101,
And then mounting rod 140 is identical apart from the distance of each positioning sliding block 120, the stability of the work of alignment pin 100 is improved.
When being full of high-pressure medium in pressure chamber 101, the pressure being applied on positioning sliding block 120 can overcome return spring
130 convergent force simultaneously drives positioning sliding block 120 to be displaced outwardly, and the inwall to nut bore is stopped with the outer end for realizing positioning sliding block 120,
Now return spring 130 is in extended state；When the high-pressure medium discharge in pressure chamber 101, return spring 130 will can be determined
Position sliding block 120 is withdrawn into initial position, and now the external diameter of alignment pin 100 is less than the internal diameter of nut bore, and alignment pin 100 can be light
Ground departs from from nut bore.
In some embodiments of the present utility model, positioning sliding block 120 is big in the length radially of dowel body 110
In the wall thickness of the periphery wall of pressure chamber 101.Thus, it is full of high-pressure medium in pressure chamber 101 and positioning sliding block 120 is displaced outwardly
During to highest distance position, the distance of the center line of the outer end Distance positioning pin body 110 of positioning sliding block 120 is more than dowel body
110 radius, the outer end of positioning sliding block 120 only can be against on the inwall of nut bore.
In some embodiments of the present utility model, high-pressure medium can be gases at high pressure or highly pressurised liquid, but be not limited to
This.
The positioner of the welded nut of the lower the utility model embodiment of the description of order below.
Above-mentioned alignment pin 100 can be included according to the positioner of the welded nut of the utility model embodiment, due to
Above-mentioned alignment pin 100 is provided with according to the positioner of the utility model embodiment, therefore the positioner can be accurately real
Existing alignment pin 100 and the positioning of nut bore, while positioner easily can also depart from from nut bore, it is rapidly right to realize
Multiple nut bores are positioned, and improve the operating efficiency of positioner.
