Description
Technical field
The present invention relates to mechanical frock technical field more particularly to a kind of double-pin auxiliary positioning guide frames.
Background technique
Positioning pin is to limit processed or assembly parts freedom degree part, its effect is exactly to control work piece or assembly
The freedom degree of part.In vehicle assembly field, finger setting is typically used to make two or more assemblies in assembling process
Reasonable rigging position is quickly reached, and keeps the relative position of assembly constant, in order to carry out assembling work.Positioning pin
By actual use situation, there are many forms, such as cylindrical positioning pins, conical-surface positioning pin, ladder-like positioning pin.
In assembly shop vehicle assembling process, needs to carry out subframe 1 and be linked and packed with vehicle body 2.As shown in Figure 1, Fig. 1
For the structural schematic diagram of the first positioning method disclosed in the prior art；Such positioning method is directly utilized in assembling process
Bolt 3 is welded by the plant on vehicle body 2 and serves as positioning pin, is cooperated with the bolt hole 4 on subframe 1 and is positioned；Such positioning method is deposited
In following defect:
(1) it plants weldering bolt 3 and serves as positioning pin, weldering bolt 3 is planted in position fixing process and is easy to cause screw thread to damage by external force extruding
It is bad；
(2) it plants weldering bolt 3 and serves as positioning pin, belong to cylindrical positioning pins, matching first positioning hole is too small, is positioning
It is not easy to be aligned in the process, employee is needed to participate in the overall process；
(3) fit clearance planted between weldering bolt 3 and bolt hole 4 is larger, and final positioning accuracy is lower, influences finally to assemble
Quality；
(4) it is the structure on assembly that vehicle body, which plants the bolt hole 4 on weldering bolt 3 and subframe 1, by different batches zero
The influence of component processing precision, each positioning accuracy change, and the homogeneity of product fluctuation after assembly is larger.
It can not then be positioned using the first positioning method for planting weldering nut 5 at 2 positioning of vehicle body.It just needs at this time
Positioning is realized in the cooperation of first positioning hole 8 increased on positioning shank 7 and vehicle body 2 in tooling 6 of lifting of subframe 1.Such as Fig. 2
Shown, Fig. 2 is the structural schematic diagram of second of positioning method disclosed in the prior art, lifts tooling 6 in subframe 1 and lifts pair
During vehicle frame 1 to rigging position, lifts the positioning shank 7 in tooling 6 and the first positioning hole 8 on vehicle body 2 cooperates, pass through
Lift the relative position that tooling 6 this standard determines vehicle body 2 Yu subframe 1.Such positioning method is that domestic vehicle assembles vehicle
Between the most common positioning method.Such positioning method has the following deficiencies:
(1) first positioning hole 8 is the positioning process hole on vehicle body sheet metal, 2 metal plate limited strength of vehicle body, in position fixing process
It is limited by stamping holes, easily leads to vehicle body sheet metal deformation, damage vehicle body and generate position error；
(2) for guarantee positioning accuracy, first positioning hole 8 must with positioning 7 diameter of shank be not much different, thus with it is existing
The first positioning method in technology, which equally exists, is not easy the problem of being aligned in position fixing process, if initial position deviation is larger
Human assistance is needed to be aligned.

Adjustment, is conveniently adjusted the position of vehicle body 2 Yu subframe 1.In this way, also can be realized in the case where larger initial positional deviation
Reliable guiding and positioning.In this way, the guide-localization in the case of larger initial positional deviation can be met, along with universal wheel 25
Using can make lift tooling 6 the second positioning pin 15 be inserted into second location hole 14 during be directed to correct position automatically,
Reduce manual operation amount.
Fig. 6 is please referred to as a preferred method, and the support plate 11 is slidably mounted in described hang in the horizontal direction
On tool 23.When it is implemented, first positioning body 9 is symmetrically mounted on suspender 23, it is arranged by sliding, two the can be adjusted
The distance between one positioning body 9, enables in the first positioning hole being inserted on vehicle body 2, by rotating the second positioning column 16,
The position that the second positioning pin 15 can be adjusted is allowed to be inserted into second location hole 14.Further, the support plate 11 with
The suspender 23 is slidably connected by dovetail groove sliding rail.It so, it is possible to guarantee the contact between suspender 23 and support plate 11
Face is larger, keeps stablizing during sliding.It is connected between the support plate 11 and the suspender 23 by telescopic rod 24.Tool
Body, the telescopic rod 24 can be the push-pull mechanism of cylinder and bar composition, be also possible to servo magnetic cylinder.More specifically, described
The one end of first positioning pin 13 far from first positioning column 12 is cone.It so, it is possible to guarantee the first positioning pin 13 and vehicle
First positioning hole cooperation on body 2.First positioning body 9 is connect with suspender 23 using telescopic rod 24, can satisfy in a certain range
It is interior adjustable, meet the needs of a variety of body widths.
Fig. 7 and Fig. 8 are please referred to, when specifically used, each lifting installation in tooling 6, there are two the second positioning bodies 10, described
There are two extreme positions for two the second positioning body 10 tools, when two second positioning bodies 10 are in the first extreme position, two second
The axial line distance of positioning pin 15 is maximum, is denoted as y；When two second positioning bodies 10 are in the second extreme position, two second positioning
The distance between pin 15 minimum, is denoted as x；The distance between the axis of second positioning pin 15 and bolt axle 17 are denoted as r, and r is not equal to
0, then y-x=4r, it may be assumed that specific embodiment proposed by the invention can be to the vehicle body 2 of deviation in a certain range and secondary vehicle
It is accurately positioned between frame 1, higher positioning accuracy can be obtained.
When it is implemented, due to having on vehicle body 2 for the benchmark and limit hole in welding, transhipment and assembling process,
The precision and intensity of the limit hole are higher, and the first positioning pin 13 is positioned with limit hole cooperation during use.Such as
This, effectively can be avoided assembly from damaging.
It will be appreciated by persons skilled in the art that the first positioning body 9 both may be mounted on suspender 23, can also install
Support horse squat on, only by change the obtained technical solution of installation site should also be as included in protection scope of the present invention it
It is interior.
It is upper that structure, feature and effect of the invention are described in detail according to embodiment shown in schema, it is described above
Only presently preferred embodiments of the present invention, but the present invention does not limit the scope of implementation as shown in the drawings, it is all according to conception of the invention
Made change or equivalent example modified to equivalent change, when not going beyond the spirit of the description and the drawings,
It should be within the scope of the present invention.
