Abstract
The utility model discloses a box fork hole tooling, which comprises a positioning plate and a connecting plate which are vertically fixed with each other, the positioning plate is provided with a drill bushing I, a round pin I and a diamond pin, the round pin I is provided with a round pin II, the axes of the round pin I, the round pin II, the diamond pin and the drill bushing I are parallel, and the round pin II is provided with a stepped bushing. The advantages of the utility model are that: the machining quality of the fork hole with a common device can be ensured, the bottleneck of difficult fork hole machining on a common device is inaccurate in positioning, the box fork hole tooling can effectively improve the positioning accuracy in an one-side two-hole positioning way, and is long in service life. The round pin and the diamond pin are provided with the bushings, and the bushings are processed with quenching, so the wear of the hole matched with the round pin and the diamond pin can be effectively reduced.
Description
Technical field
The utility model relates to the frock technical field, especially relates to a kind of casing shift fork hole tool.
Background technology
At present, the processing in the casing shift fork hole of automobile and engine producer both at home and abroad on special purpose transfer machine, adopt mostly heavy boring then the mode of right boring accomplish, or adopt first heavy boring to cut with scissors at a high speed again and accomplish.The used special purpose transfer machine advantage of these two kinds of processing modes is given prominence to, and precision is higher.But, drop into height, flexible poor, be difficult for promoting the use of.On common equipment, process; Since the aperture, shift fork hole of casing usually at
～
between; Hole length is between 400mm～700mm; Axiality, the depth of parallelism are strict; On common boring machine equipment, adopt the mode of brill, boring, hinge to process; Repair rate, scrappage are very high, are difficult to reach technological requirement.Therefore be necessary to design a kind of frock.
The utility model content
To the deficiency that above-mentioned prior art exists, the purpose of the utility model provides a kind of casing shift fork hole tool, and it has the characteristics of the crudy that on conventional equipment, can guarantee casing shift fork hole.
To achieve these goals; The technical scheme that the utility model adopted is: casing shift fork hole tool, comprise the location-plate and the connecting plate of mutual vertical fixing, and said location-plate is provided with drill bushing I, straight pin I and rhombus pin; Be provided with the straight pin II in the straight pin I; And straight pin I, straight pin II, rhombus pin are all parallel with the axle center of drill bushing I, and simultaneously, the straight pin II is furnished with the step lining.
Parallel with location-plate bushing plate I and the bushing plate II of being fixed with on the said connecting plate; Be respectively equipped with drill bushing II and drill bushing III on bushing plate I and the bushing plate II, and drill bushing I, drill bushing II, drill bushing III are coaxial.
Be embedded with lining II and lining III on said bushing plate I and the bushing plate II respectively, and the axis parallel of the axle center of lining II and lining III and drill bushing I, simultaneously, lining II and lining III all match with the straight pin II.
Said rhombus pin is furnished with the lining I.
Be provided with gusset between said location-plate and the connecting plate.
After adopting said structure, the utility model is compared the advantage that is had with prior art and is: the crudy that 1, on conventional equipment, can guarantee the shift fork hole.The bottleneck that on conventional equipment, is difficult for processing shift fork hole is to locate inaccurate.This frock effectively raises the accurate of location with the Position with One Plane and Two Holes locate mode.During use this frock is pushed workpiece, treat that frock and workpiece are assembled to correct position after, pack the step lining in the stepped hole of workpiece into, insert the rhombus pin then, straight pin positions.Like this, in conjunction with the effect of drill bushing, well guaranteed the axiality and the depth of parallelism in institute processing shift fork hole.And employed rhombus pin had both guaranteed to have prevented the overdetermination position again by the accurate of location.After particularly optimizing, set up bushing plate I, bushing plate II after, effectively improved the guidance quality of drill bushing, make crudy higher.And further optimize, be connected with gusset between location-plate and the connecting plate, increased the rigidity of frock.2, frock long service life.Straight pin and rhombus pin all are furnished with lining, and lining can pass through the processing of hardening, and effectively reduce the wearing and tearing in the hole that straight pin, rhombus pin match with it like this.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
Fig. 1 is that the master of the utility model looks the sectional structure sketch map.
Among the figure: 1, location-plate; 2, straight pin I; 3, straight pin II; 4, rhombus pin; 5, lining I; 6, lining II; 7, lining III; 8, connecting plate; 9, drill bushing I; 10, drill bushing II; 11, drill bushing III; 12, gusset; 13, bore the lamina membranacea I; 14, bore the lamina membranacea II; 15, step lining.
The specific embodiment
The following stated is merely the preferred embodiment of the utility model, does not therefore limit the protection domain of the utility model.
Embodiment, see shown in Figure 1: casing shift fork hole tool comprises location-plate 1, bushing plate I 13 and bushing plate II 14 and connecting plate 8.Location-plate 1, bushing plate I 13 and bushing plate II 14 are parallel to each other and an all vertical side that is fixed in connecting plate 8.In order to increase the rigidity of frock, be provided with gusset 12 between location-plate 1 and the connecting plate 8.Be respectively equipped with drill bushing I 9, drill bushing II 10 and drill bushing III 11 on location-plate 1, bushing plate I 13 and the bushing plate II 14.Obviously, drill bushing I 9, drill bushing II 10 and drill bushing III 11 are coaxial.Location-plate 1 is provided with straight pin I 2 and rhombus pin 4, is provided with straight pin II 3 in the straight pin I 2.And straight pin I 2, straight pin II 3, rhombus pin 4 are all parallel with the axle center of drill bushing I 9.Certainly, all have on bushing plate I 13 and the bushing plate II 14 and be used for the through hole that straight pin II 3 is passed through, and the through hole of bushing plate I 13 is embedded with the through hole of lining II 6, bushing plate II 14 and is embedded with lining III 7.The axle center of lining II 6 and lining III 7 and the axis parallel of drill bushing I 9, simultaneously, lining II 6 all matches with straight pin II 3 with lining III 7, that is, but being enclosed within on the straight pin II 3 of lining II 6 and lining III 7 equal matched in clearance.Rhombus pin 4 is furnished with lining I 5 equally.All linings all can pass through the processing of hardening.For cooperating of auxiliary mould and workpiece, the stretching of straight pin II 3 toward an end of the stepped hole of workpiece, promptly the top is furnished with step lining 15.
The operating procedure of the utility model: during use this frock is pushed workpiece, treat that frock and workpiece are assembled to correct position after, pack step lining 15 in the stepped hole of workpiece into, insert rhombus pin 4 then, straight pin II 3 positions.On common process equipment, process afterwards.
