Description
Technical field
The utility model relates to auto parts and components machining tool, the aperture more specifically to Study on Vehicle Front Wheel House is positioned
Fixture.
Background technique
Damper is to eliminate the vibration of road surface bring, improve riding stability, to the weight of driver's comfort and sense of stability
Want mechanism.Damper is located on the front wheel housing of automobile.Fig. 1 discloses mounting structure of the damper on front wheel housing.Such as Fig. 1 institute
Show, damper location hole 104 is offered on front wheel housing 102, and damper 106 is installed to front-wheel by damper location hole 104
On cover 102.The positioning accuracy request of damper is higher, if the positioning accuracy of damper it is not up to standard will will affect four-wheel aligner and
Driving experience.The positioning accuracy of damper is mainly determined by the precision of the damper location hole on front wheel housing.Because of welding process
In there are error accumulation, the precision of location hole when to guarantee damper installation, damper location hole needs to complete in vehicle body welding
After reposition aperture, and the punching on front wheel housing part in indirect manufacturing process.
In the prior art, the center of circle that damper location hole is first marked with formed punch is generallyd use, then with power drill to director circle
The mode of heart progress aperture.Fig. 2 a and Fig. 2 b disclose the positioning device of damper location hole used in the prior art.Wherein
Fig. 2 b is the partial enlarged view of part A in Fig. 2 a.With reference to shown in Fig. 2 a and Fig. 2 b, which includes: bracket 202, rocker arm
204, connector 206, formed punch bootstrap block 208 and formed punch 210.Rocker arm 204 is mounted on bracket 202.Equipped with perpendicular on bracket 202
Histogram to sliding rail, rocker arm 204 can sliding rail along vertical direction it is mobile to adjust its vertical position.Connector 206 is installed
In the end of rocker arm 204, connector 206 clamps front wheel housing 102.Formed punch bootstrap block 208 is mounted on connector 206.Formed punch draws
Formed punch guide hole 209 is provided on guide block 208, the partial enlarged view with reference to shown in Fig. 2 b is shown on formed punch bootstrap block 208
Formed punch guide hole 209.Formed punch 210 is installed in formed punch guide hole 209.208 pilot punch 210 of formed punch bootstrap block is directed at front wheel housing
The center of upper damper location hole.
Fig. 3 discloses the formed punch bootstrap block of the positioning device of damper location hole used in the prior art and cutting for formed punch
Face figure.As shown in figure 3, after formed punch 210 is placed into the formed punch guide hole 209 on formed punch bootstrap block 208, before formed punch 201 is aligned
The center 103 of damper location hole on wheel cover 102.It is shown in Fig. 3 in the prior art, formed punch bootstrap block 208 primarily serves one
