Description

Pin positioning device for use
Technical field
The utility model relates to a kind of forcing press, particularly is used for a kind of device of workpiece location on the forcing press.
Background technology
Existing automobile longitudinal girder numerical control punching production is to adopt forcing press to carry out punching processing, when on same plate, carrying out punching once more (perhaps replenishing punching), need location once more, existing detent mechanism has centering body (Y is to the location) and photoelectric induction type positioner (X is to the location); Because the burr of plate itself present the out-of-flatness state, and the restriction that is subjected to existing positioner positioning accuracy, once more behind the location; The pitch-row precision of mending punching and original hole that dashes may just not reach pitch-row precision that lathe itself is guaranteed.To this problem, still there is not solution in the prior art.
The utility model content
The purpose of this utility model provides a kind of pin positioning device for use, and forcing press can utilize punching first to position, and carries out secondary punching processing, to guarantee the precision of pitch of holes.
The purpose of this utility model is achieved in that a kind of pin positioning device for use, comprise the rebound that is connected with pressure machine cross-beam, be horizontally installed with base on the rebound, base is provided with chute, cooperate in the chute and be provided with slide, slide and base fix, the slide upside is provided with the positioning sleeve of hollow, cooperate in the positioning sleeve and be provided with guide pillar, the guide pillar upper end is fixed with alignment pin, the slide downside is connected with the cylinder of vertical setting through air cylinder fixed plate, and guide pillar, alignment pin and cylinder are coaxially set, and the piston rod external part of described cylinder is fixedlyed connected with the guide pillar lower end.
The utility model is connected with pressure machine cross-beam by rebound, adds man-hour in secondary punching, and the cylinder action drives alignment pin and stretches out, and is inserted in the hole of going out for the first time, realizes the workpiece location, and then workpiece is carried out secondary punching.Initial position location can be by transition seat and pressure machine cross-beam the relative position of link position, slide and chute determine.Compared with prior art, this device is that benchmark positions with the hole of last time processing, carries out the processing of secondary pore again, can guarantee that the precision of pitch of holes is higher.This device can be used for the secondary punching processing of plate, is particularly useful on the automobile longitudinal girder automatic punching machining production line.
For ease of adjusting the initial alignment position, be positioned at chute one end on the described base and be fixed with screw bolt seat, screw-threaded engagement is connected with screw rod on the screw bolt seat, and screw rod one end is rotatably connected on the connecting plate, and described connecting plate is connected the positioning sleeve side; Described slide both sides are provided with the groove that runs through of bar shaped, and lock-screw passes and runs through groove and fixedly connected with base.When adjusting the position, unclamp lock-screw, by rotating screw bolt, slide can tighten up lock-screw along the chute shift position behind the appropriate location; So that make the locating hole of alignment pin on the workpiece.
In the locating hole on the alignment pin insertion workpiece, the described alignment pin tapered contraction in upper end.Can overcome out-of-flatness of plate burr and the coarse problem of plate placement location,, can make plate move to the exact position by the insertion of alignment pin.
Stretch out for ease of alignment pin, be provided with axle bush between described positioning sleeve and the guide pillar.Axle bush plays guiding and wear-resisting effect, has further guaranteed the dependability of device.
Description of drawings
Fig. 1 is the utility model stereogram.
Fig. 2 is the utility model partial structurtes schematic diagrames.
Wherein, 1 rebound, 2 run through groove, 3 slides, 4 chutes, 5 cylinders, 5016 bases, 7 screw rods, 8 screw bolt seats, 9 air cylinder fixed plate, 10 connecting plates, 11 positioning sleeves, 12 alignment pins, 13 guide pillars, 14 axle bushes, 15 lock-screws.
The specific embodiment
Shown in Fig. 1-2, be pin positioning device for use, its structure mainly comprises the rebound 1 that is connected with pressure machine cross-beam, is horizontally installed with base 6 on the rebound 1, and base 6 is provided with chute 4, cooperate in the chute 4 and be provided with slide 3, what slide 3 both sides were provided with bar shaped runs through groove 2, and lock-screw 15 passes and runs through groove 2 and fixedly connected with base 6, and slide 3 and base 6 are fixed, unclamp lock-screw 15, slide 3 can be along chute 4 shift positions; Slide 3 upsides are provided with the positioning sleeve 11 of hollow, cooperate in the positioning sleeve 11 to be provided with guide pillar 13, are provided with axle bush 14 between positioning sleeve 11 and the guide pillar 13, with convenient guiding; Guide pillar 13 upper ends are fixed with alignment pin 12, the tapered contraction in alignment pin 12 upper ends; Slide 3 downsides are connected with the cylinder 5 of vertical setting through air cylinder fixed plate 9, guide pillar 13, alignment pin 12 and cylinder 5 are coaxially set, cylinder 5 is by being arranged on piston 502 in cylinder body 501, the cylinder body and piston rod 503 is formed, wherein, cylinder body 501 is fixed on air cylinder fixed plate 9 downsides, and the external part of the piston rod 503 of cylinder 5 is fixedlyed connected with guide pillar 13 lower ends; Be positioned at chute 4 one ends on the base 6 and be fixed with screw bolt seat 8, screw-threaded engagement is connected with screw rod 7 on the screw bolt seat 8, and screw rod 7 one ends are rotatably connected on the connecting plate 10, and connecting plate 10 is connected positioning sleeve 11 sides.
This device can be used on the automobile longitudinal girder automatic punching production line two fabrication holes being arranged on automobile longitudinal girder, and can make locating hole and use, the longeron plate of (perhaps batch) of a model, the size and location of locating hole are changeless; Two of above-mentioned pin positioning device for use are installed on the material loading crossbeam, X near the pin positioning device for use of main frame is to be provided with in advance to fix to the position, an other pin positioning device for use and before the X of pin positioning device for use be to determine to relative distance according to the distance between two locating holes of plate.The position of alignment pin 12 center lines of pin positioning device for use overlaps to initial point with lathe Y, can regulate the position of positioning sleeve 11 by screw rod 7.Once more punching the time, carry out coarse positioning by centering body and photoelectric induction type positioner, according to the coarse positioning result, digital control system calculates the relative position distance of locating hole and alignment pin 12, mobile then plate, locating hole is alignd substantially with alignment pin 12, cylinder 5 promotion alignment pins 12 are up then, insert in the locating hole, between alignment pin 12 and the locating hole tolerance fit arranged, the grade of tolerance is consistent with machine finish, can guarantee positioning accuracy.There is certain taper on alignment pin 12 tops simultaneously, even the coarse positioning between locating hole and the alignment pin 12 exists than large deviation, alignment pin 12 also can insert the locating hole on the workpiece easily, reaches the location purpose.Like this, the location of punching is a benchmark with above-mentioned locating hole just once more, has got rid of the influence of out-of-flatness of plate burr and coarse positioning low precision, and the punching precision is improved.
