Background technology
, it is necessary to which the stamping manufacture characteristic of combination product, reasonable in design when metal plate product parts are positioned using hole
Hole locating check fixture structure.The especially positioning of metal plate irregularly-shaped hole, because diel is in long-term punching course, drift can be by
Gradually wear and tear, the trend of batch sizes reduction can be presented in the metal plate irregularly-shaped hole gone out.Therefore, the cubing positioned for metal plate irregularly-shaped hole
Structure design, it should in the defined margin of tolerance, makes adjustable form placed in the middle by location structure as far as possible.It can so avoid
When irregularly-shaped hole is bigger than normal, positioning is bad, and middle position is inaccurate；Or irregularly-shaped hole it is less than normal when, alignment pin cannot be introduced into holes of products, cause
The situation of failure.
The content of the invention
Tunable arrangement is centered about it is an object of the invention to provide a kind of new irregularly-shaped hole, the irregularly-shaped hole in product is solved
When the irregularly-shaped hole existed during positioning is bigger than normal, positioning is bad, and middle position is inaccurate；Or irregularly-shaped hole it is less than normal when, alignment pin can not enter
The problem of entering holes of products.
The technical scheme is that：A kind of irregularly-shaped hole is centered about tunable arrangement, it is characterised in that including upper localization machine
Structure, lower detent mechanism, taper bolt, bearing and handle, are provided with guide holder in the front side of holder top, are set on the top of the guide holder
There is axle center hole, the cylinder of taper bolt bottom, which is slided, to be loaded in the axle center hole of the guide holder, and spiral shell is provided with the bottom of the axle center hole
Hole, the screw rod of handle screws in the screw behind bearing, and is connected with the bottom rotation of cylinder；Upper detent mechanism and lower fixed
Position mechanism respectively symmetrically is located above and below taper bolt.
Described upper detent mechanism includes upper alignment pin, upper arm and upper spring, and one end of upper arm is vertically connected on bearing
Installed in front side, the longitudinal hole on the upper arm and be merely able to the ground alignment pin that slides axially, bottom of alignment pin is with being somebody's turn to do on this
Upper spring is housed, top of alignment pin is provided with positioning end corresponding with the profiled holes of product on this between below upper arm,
Lower end of alignment pin is provided with the cambered surface that is in contact with the taper bolt conical surface on this, and the lower end of described upper spring is with being inserted radially on this
The upper spring finger setting of alignment pin bottom；The structure of described lower detent mechanism is identical with described upper detent mechanism.
Described upper alignment pin and lower alignment pin are non-cylinder.
The section of described non-cylinder is D-shaped；It is installed with the longitudinal hole of described upper arm and underarm with being somebody's turn to do
The D-shaped bushing that the section of upper alignment pin and lower alignment pin is slidably matched.
Fixed between described D-shaped bushing and upper alignment pin and lower alignment pin with connecting key.
It is an advantage of the invention that：Using the taper of taper pin, regulation taper pin and alignment pin and the contact position of symmetrical alignment pin,
So as to realize the adjustment of locating surface distance between two alignment pins；Taper pin axial location is the theoretical position at product orientation hole center
Put, because two side-locating faces are symmetrical with respect to the center line of taper pin, the accuracy of profiled holes middle position can be effectively ensured.Realize
The placed in the middle and location dimension regulation of metal plate product profiled holes locating surface, solve the special-shaped punching hole size of metal plate product it is uneven,
The problem of being difficult to be accurately positioned.Simple in construction, easy to operate, function is reliable.

Embodiment
Referring to Fig. 1-Fig. 4, a kind of irregularly-shaped hole of the invention is centered about tunable arrangement, including upper detent mechanism, lower localization machine
Structure, taper bolt 4, bearing 7 and handle 8, are provided with guide holder 71 in the front side on the top of bearing 7, are provided with the top of the guide holder 71
Axle center hole 72, the cylinder 41 of the bottom of taper bolt 4, which is slided, to be loaded in the axle center hole 72 of the guide holder 71, at the bottom of the axle center hole 72
End is provided with screw, and the screw rod of handle 8 screws in the screw behind bearing 7, and is connected with the bottom rotation of cylinder 41；It is upper fixed
Position mechanism and lower detent mechanism respectively symmetrically are located above and below taper bolt 4.
Described upper detent mechanism includes upper alignment pin 1, upper arm 2 and upper spring 3, and one end of upper arm 2 is vertically connected on branch
Installed in the front side of seat 7, the longitudinal hole on the upper arm 2 and be merely able to the ground alignment pin 1 that slides axially, alignment pin 1 on this
Upper spring 3 is housed, top of alignment pin 1 is provided with corresponding with the profiled holes of product on this between below bottom and the upper arm 2
Positioning end, lower end of alignment pin 1 is provided with the cambered surface that is in contact with the conical surface of taper bolt 4 on this, the lower end of described upper spring 3
