Summary of the invention
The utility model is to deficiency of the prior art, provide a kind of can be with hook-shaped piece-holder more stable, better guarantee machining accuracy, and the boring grab of suitable different model, different profile, the processing of different size workpiece.
In order to solve the problems of the technologies described above, the utility model is able to solve through following technical proposals:
Boring grab; Comprise base plate and work holder, also comprise hook-shaped Working piece positioning device, said hook-shaped Working piece positioning device comprises chute, chute supporting, locating piece, alignment pin and locating piece locking device; The bottom of said locating piece is embedded in the chute supporting; Said locating piece is provided with at least one locating hole, and said alignment pin inserts in the locating hole, and hook-shaped workpiece to be processed colludes on alignment pin.According to the different size of hook-shaped workpiece, the slip locating piece is fixed locating piece through the locating piece locking device to the position that is fit to, and alignment pin promptly becomes the limited post of hook-shaped workpiece hook part.The location of hook-shaped workpiece hook part, it is more stable to make that boring adds man-hour hook-shaped whole workpiece, thereby makes boring processing more accurate.
As preferably; Said locating piece locking device comprises clamping screw, and said base plate interior is provided with the screwed hole that matches with clamping screw, and clamping screw is through in the screwed hole; The bar end surface of clamping screw peaks at locating piece, and the head of clamping screw is positioned at the outside of base plate.Through the fastening locating piece of clamping screw, simple in structure, simple operation.
As preferably, said work holder comprises jig arm, jig arm support, locking nut and pinching screw, and pinching screw is threaded onto in the locking nut, props up the jig arm in the jig arm support.According to the different size of hook-shaped workpiece, the rotation pinching screw can prop up hook-shaped workpiece with jig arm makes its clamping, simple in structure, easy to operate.
As preferably; Also comprise drill bushing and drill bushing fixture, said drill bushing fixture comprises drill bushing fixed head, fixed head supporting, packing ring and fixed head trip bolt, and said drill bushing fixed head one side is provided with the drill bushing installing hole; Opposite side is provided with the fixed installation hole; Said drill bushing is embedded in the drill bushing installing hole, and said fixed head supporting is through at the fixed installation hole, and the top that said packing ring and fixed head trip bolt are located at the fixed head supporting is anchored on the fixed head supporting with the drill bushing fixed head.Drill bushing is fixed through the drill bushing fixed head, and is more steady, and the boring machining accuracy is higher.Through the fixing drill bushing fixed head of fixed head supporting, packing ring and fixed head trip bolt, simple in structure, installation and removal are more convenient.Drill bushing can be changed arbitrarily according to the size of hole in piece part, and the drill bushing material generally adopts carbide alloy.
As preferably, said locating hole and alignment pin are four.The spacing of four alignment pins can only need change diverse location during use according to the size design of normal processing work, makes operation easier, and production efficiency is higher.
According to the technical scheme of the utility model, can be with hook-shaped piece-holder more stable, better guarantee machining accuracy, and suitable different model, different profile, the processing of different size workpiece.Easy to adjust in the use, reliable and stable, efficient is high.The wide ranges of converted products, it is young to have covered polytypic multistage cold former folder.
