Description

Synchronous sliding sleeve drift drilling jig gripper
Technical field
The utility model relates to a kind of fixture, particularly a kind of synchronous sliding sleeve drift drilling jig gripper.
Background technology
Synchronous sliding sleeve is that in automotive transmission, the synchronized parts are realized one of strength member of gear shift, drift as shown in Figure 3 and Figure 4 is the main cutting tools for cutting of processing three, fourth gear synchronous sliding sleeve internal spline, the installation principle of this drift is to be arranged in three locating slots of Special punching die clamper with 120 ° of circumference three equal parts, once use three drifts, installation accuracy is high, and the main cause that affects installation accuracy is: the AXIALLY SYMMETRIC PROBLEMS of both sides, hole to be processed and center, hole to be processed are to the length variation of rear end face.
can find out from Fig. 3 and Fig. 4, this drift required precision is high, the drift upper base is long is L1, L1 is 32.3 ± 0.02mm, drift is gone to the bottom to grow and is L2, L2 is 35.23 ± 0.02mm, the drift front end is wide is L3, L3 is 1.95 ± 0.05mm, the drift rear end is wide is L4, L4 is 16+0.006 mm or 16-0.005mm, the drift height is H1, H1 is 16+0.05mm, drift hole to be processed centre distance drift rear end face is D1, D1 is 12 ± 0.1mm, before center, drift hole to be processed is arranged on drift, on the center line of rear end, this shows, the positional precision of controlling center, drift hole to be processed is very important.Technical process: corase grind---boring---heat treatment---correct grinding---mill salient angle.Although carried out technology controlling and process during boring, still there are several shortcomings in existing processing method.
(1) for a long time, processing only rely on during drift the operator rule the technique processing method at center, centering drift hole to be processed guarantee the hole the position (positional precision that general operation person guarantees is 0.5mm---1.0mm), positional precision is low, the very difficult control in Central Symmetry position in hole, be subjected to simultaneously the impact of operator's technology, quality with series-produced drift is also unstable, causes the considerable part drift can not be arranged in the locating slot of Special punching die clamper.Because the position deviation in hole is larger, can not be arranged on exactly in the locating slot of Special punching die clamper, scrap for avoiding drift, reduce the loss, have to carry out reaming and reprocess, to process and use, repair rate is up to 30%~40%.At this moment, it is HRC56~58 that drift is also heat-treated hardness, (is coordinated to receive the carbide alloy reamer in subsidiary factory by unit, more than 900 yuan of expense), because drift hardness is high, easily reamer is beaten and is lacked and can not use, repair rate and expense cause production cost and economic cost higher.
(2) owing to adopting the rule method at center, centering drift hole to be processed by the operator, positional precision is low, and the center in hole and symmetry are difficult to control, and 100 drifts just need the 3-4 days time centering of ruling, and operating efficiency is extremely low.
(3) on the workbench of drilling machine, with vice clamping drift, mobile vice makes the center, drift hole to be processed of drill bit line, because every drift can not be clamped in same position, make every all will carry out centering by mobile vice, vice is 20kg heavily approximately, and operator's labour intensity is large, non-cutting time is long, wastes time and energy.
(4) work efficiency is too low, is not suitable for the tissue batch production.
Summary of the invention
The purpose of this utility model is the deficiency that exists for prior art, provides a kind of drilling quality stable, the synchronous sliding sleeve drift drilling jig gripper that efficient is high.
The purpose of this utility model is achieved in that
a kind of synchronous sliding sleeve drift drilling jig gripper, comprise base, and be fixed on right angle location-plate and supporting seat on base, the right angle face of described right angle location-plate vertically is provided with the up and down two end plates, upper head plate and bottom plate are parallel to each other, described upper head plate is provided with the drill bushing hole, in the drill bushing hole, cover has drill bushing, described drill bushing hole, drift hole to be processed be centered close to same axis, described bottom plate is provided with chip-removal hole, described supporting seat is provided with the screwed hole that laterally runs through supporting seat, the screwed hole that one screw rod one end passes supporting seat is fixedly connected with a sliding clamp, the screw rod other end is fixedly connected with handwheel, drive sliding clamp by rotation hand wheel and compress the drift that is positioned on bottom plate.
Described chip-removal hole is rectangle, and rectangular minor face is longer than drift bore dia to be processed.
Described chip-removal hole is centered close on axis through the center in drill bushing hole, drift hole to be processed.
Described bottom plate lower surface is provided with floor.
The beneficial effects of the utility model are: because the right angle face of the right angle location-plate of this synchronous sliding sleeve drift drilling jig gripper vertically is provided with the up and down two end plates, drift is placed on bottom plate, compress drift by sliding clamp, make drift be positioned at the place, right angle of right angle location-plate, only need the position of hole to be processed according to drift on drift, the center, drill bushing hole of determining upper head plate respectively with the distance of right angle location-plate both ends of the surface, can guarantee that the bore position precision is high, drilling quality is stable.This drilling jig gripper is owing to adopting the method that drift is clamped in same position, not needing the operator to rule does not need center, the hole to be processed of centering drift yet, high efficiency, and saved time at the center, hole to be processed of a large amount of line and centering drift, need not use vice clamping drift, reduced operator's labour intensity, the bore position precision is high, and drilling quality is stable, has avoided drift to scrap, reduced loss, suitable tissue batch production.This fixture adopts the separation structure design, and part is easily made and repair, and low cost of manufacture.
