Abstract
The utility model relates to a drilling mould for a rear pulling rod head. The drilling mould for the rear pulling rod head mainly resolves the problems that in the drilling process, the drilling force causes deformation of the rear pulling rod head, and an upper hole and a lower hole of the rear pulling rod head are not coaxial. The drilling mould for the rear pulling rod head is characterized in that a guide pillar A (3) and a guide pillar B (7) are installed on a drilling mould lower plate (1) and are provided with cylinder spiral compressing springs (8), the guide pillar A (3) is connected with a drilling mould upper plate (2), the guide pillar B (7) is connected with a middle plate (6), and the drilling mould upper plate (2) is provided with a drilling mould sleeve (5) which is fixed through a hexagon socket cap screw (10). The drilling mould for the rear pulling rod head has the advantages of being high in drilling accuracy, short in work period and replaceable in drilling sleeve.
Description
Technical field
The utility model relates to a kind of mechanical field, especially a kind of back stay head drill jig tool.
Background technology
It is the device that produces brake force that lock on vehicle is adjusted device, and lock adjusts the quality of device directly to have influence on vehicle operating safety; The back stay head is adjusted in device and has been played and connected and stressed effect at lock, and especially whether the 5mm eccentric orfice of back stay head meets specification requirement directly affects vehicle operating safety; Existing back stay head drill jig tool accurate rate in process is not high, and in drilling process, the drill bit downforce easily makes the distortion of back stay head, causes upper and lower two hole disalignments, has increased and has worn the pin difficulty; Job flow time is long, and production efficiency is low; When drill bushing mill amount is large, can only reject drill bushing, repeatedly the drill bushing hole can become greatly, lose efficacy afterwards, causes bushing plate to be scrapped, and the waste resource, raise the cost.
Summary of the invention
For overcoming the deficiency existed in background technology, the utility model provides a kind of back stay head drill jig tool, has that the drilling accuracy is high, workflow is short, the removable characteristics of drill bushing.
The technical scheme that the utility model adopts is: a kind of back stay head drill jig tool, comprise drill jig lower plate, drill jig upper plate, guide pillar A and guide pillar B are installed on described drill jig lower plate, on guide pillar A and guide pillar B, cylindroid helical-coil compression spring is arranged, guide pillar A connects the drill jig upper plate, guide pillar B connecting middle plate, have drill jig sleeve to be fixed by interior hexagonal cylindrical screw on described drill jig upper plate.There are guide pin bushing and circlip for shaft in described drill jig upper plate and guide pillar A junction.
The utlity model has following beneficial effect: the utility model has adopted the profile location, blast clamps, spring supporting, make positioning datum more accurate, guaranteed the coaxial specification requirement in upper and lower two holes under the prerequisite that guarantees eccentric 5mm, and adopted replaceable drill jig sleeve, after having prevented from repeatedly using, the drill bushing hole becomes adverse effect large, that lost efficacy and cause bushing plate to be scrapped, saving resource, reduce costs.
The accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is top view of the present utility model.
1-drill jig lower plate in figure, 2-drill jig upper plate, 3-guide pillar A, 4-guide pin bushing, 5-drill jig sleeve, plate in 6-, 7-guide pillar B, 8-cylindroid helical-coil compression spring, 9-circlip for shaft, hexagonal cylindrical screw in 10-.
The specific embodiment
Shown in Fig. 1, Fig. 2, the utility model comprises drill jig lower plate 1, drill jig upper plate 2, guide pillar (A) 3 and guide pillar (B) 7 are installed on drill jig lower plate 1, on guide pillar (A) 3 and guide pillar (B) 7, cylindroid helical-coil compression spring 8 is arranged, guide pillar (A) 3 connects drill jig upper plate 2, guide pillar (B) 7 connecting middle plates 6, have drill jig sleeve 5 fixing by interior hexagonal cylindrical screw 10 on described drill jig upper plate 2.
During this back stay head drill jig tool work, workpiece is put into to drill jig lower plate 1, middle plate 6 plays the effect that supporting workpiece prevents the drilling distortion, in assurance, drill jig upper plate 2 is parallel with drill jig lower plate 1, open the reservoir blast, compress drill jig upper plate 2, make drill jig upper plate 2 and Work-sheet pressing, start radial drilling machine, workpiece is carried out to drilling until drilling completes, close the reservoir blast, utilize the cylindroid helical-coil compression spring 8 on guide pillar 3 that drill jig upper plate 2 is upspring, workpiece is unloaded, utilize air pressure gun that iron filings in the drill jig tool are blown out to the assurance free from admixture by chip area, for processing next time is prepared; Prevent after repeatedly using that drill jig sleeve 5 wearing and tearing are excessive, detachably change the drill jig sleeve 5 fixing by interior hexagonal cylindrical screw 10.
Claims (2)
1. a back stay head drill jig tool, comprise drill jig lower plate (1), drill jig upper plate (2), it is characterized in that: described drill jig lower plate (1) is above installed guide pillar A(3) and guide pillar B(7), guide pillar A(3) and guide pillar B(7) on cylindroid helical-coil compression spring (8) is arranged, guide pillar A(3) connect drill jig upper plate (2), guide pillar B(7) connecting middle plate (6), have drill jig sleeve (5) fixing by interior hexagonal cylindrical screw (10) on described drill jig upper plate (2).
2. back stay head drill jig tool according to claim 1 is characterized in that: described drill jig upper plate (2) and guide pillar A(3) there are guide pin bushing (4) and circlip for shaft (9) in junction.
