Summary of the invention
The utility model technical problem to be solved is the present situation to prior art, and provides a kind of simple in structure, clamps the location conveniently, improves the positioner that is used to process cylinder inner bore of machining accuracy and quality.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of positioner that is used to process cylinder inner bore; It is characterized in that; Comprise fixed head, slide plate, centralized positioning post and drag hook, drag hook passes the inside of fixed head simultaneously, and the lower part of drag hook is fixedly connected with slide plate; Described centralized positioning post is positioned at the center of fixed head and adapts with the center bore of product and cooperates; Processed product is placed on fixed head, and actuating unit drives slide plate and drives the drag hook motion, drag hook is pressed on the processed product positions.
The measure of taking for the optimization such scheme specifically comprises:
At above-mentioned a kind of positioner that is used for processing cylinder inner bore; Described drag hook is evenly distributed; Quantity is 3, on drag hook, offers draw-in groove, offers locating hole at the fixed head sidepiece; Described locating hole corresponding position is equipped with keeper, after drag hook is pressed on the processed product, prevents that through the keeper of screwing drag hook from further moving.Here drag hook be evenly distributed be in the location during product stressed evenly.
At above-mentioned a kind of positioner that is used for processing cylinder inner bore, described draw-in groove is divided into dextrorotation draw-in groove and left-handed draw-in groove.Here draw-in groove adopt dextrorotation and left-handed be in order to rotate drag hook, to help clamping of product.
At above-mentioned a kind of positioner that is used for processing cylinder inner bore, the head of described drag hook is hook-shaped.Here being hook-shaped head can position product securely, is beneficial to next step Digit Control Machine Tool three endoporus of cylinder body are processed.
At above-mentioned a kind of positioner that is used for processing cylinder inner bore, described fixed head is provided with support bar, and processed product is placed on the fixed head and by they sup-port.
Compared with prior art, the advantage of the utility model is simple in structure, clamps the location conveniently; Efficient is high; Can the stable location securely of cylinder body to be processed be lived,, guarantee machining accuracy and quality so that next step numerically controlled lathe cutter carries out fine finishining to three endoporus of cylinder body.
Description of drawings
Fig. 1 is the perspective view that originally is used to process the positioner of cylinder inner bore;
Fig. 2 is the structural representation that originally is used to process after cylinder inner bore clamps product;
Fig. 3 is the drag hook structural representation that originally is used for processing the positioner of cylinder inner bore.
The specific embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technical scheme of the utility model is done further to describe, but the utility model is not limited to these embodiment.
Among the figure, fixed head 1; Locating hole 1a; Slide plate 2; Support bar 3; Drag hook 4; Draw-in groove 4a; Dextrorotation draw-in groove 4a1; Left-handed draw-in groove 4a2; Centralized positioning post 5; Product 6; Centre bore 6a; Endoporus 6b.
As shown in Figure 1, the positioner that originally is used to process cylinder inner bore 6b mainly is to be used for clamping cylinder body, so that carry out accurately machined to three endoporus 6b of cylinder interior; Comprise fixed head 1, slide plate 2, centralized positioning post 5 and drag hook 4, drag hook 4 passes the inside of fixed head 1 simultaneously, and the lower part of drag hook 4 is fixedly connected with slide plate 2; The head of drag hook 4 is hook-shaped; Here being hook-shaped head can position product 6 securely, be beneficial to next step Digit Control Machine Tool three endoporus 6b of cylinder body are processed, and drag hook 4 is evenly distributed; Quantity is 3, here drag hook 4 be evenly distributed be in the location during product 6 stressed evenly.
As shown in Figure 3, on drag hook 4, offer draw-in groove 4a, draw-in groove 4a is divided into dextrorotation draw-in groove 4a1 and left-handed draw-in groove 4a2, here draw-in groove 4a adopt dextrorotation and left-handed be in order to rotate drag hook 4, to help clamping of product 6.
Offer locating hole 1a at fixed head 1 sidepiece, locating hole 1a corresponding position is equipped with keeper, after drag hook 4 is pressed on the processed product 6, prevents that through the keeper of screwing drag hook 4 from further moving.
Centralized positioning post 5 is positioned at the center of fixed head 1 and directly adapts with the centre bore 6a of product 6 and cooperates, and processed product 6 is placed on fixed head 1, and fixed head 1 is provided with support bar 3, and processed product 6 is placed on the fixed head 1 and by support bar 3 and supports.
