The utility model aims at providing a when overcoming present drilling, because the variation in size of part, the skew can take place at the center of part to reduce machining efficiency's not enough, and the drilling and tapping positioner of being convenient for chip removal that proposes.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a drilling and tapping positioning device convenient for chip removal comprises a fixing ring, wherein a limiting block is arranged on the side wall of one end in the fixing ring, three positioning pins penetrate through the side wall in the fixing ring, one ends of the three positioning pins are fixed with positioning blocks, springs are sleeved on the three positioning pins, one ends of the springs extend and are fixed on the positioning blocks, and the other ends of the springs are fixed on the side wall of one end in the fixing ring;
be fixed with three nut on the retainer plate, be equipped with three jack on the retainer plate, and jack and three nut correspond the setting, all run through in the three nut and be equipped with adjusting screw, adjusting screw's one end is fixed with the turning block, adjusting screw's other end screw thread cup joints on the nut, adjusting screw's one end runs through the jack and extends to in the retainer plate, adjusting screw's one end is rotated and is connected with and presss from both sides tight piece.
Preferably, the lower end of the fixing ring is provided with four notches.
Preferably, one end of each of the three clamping blocks is arranged in an arc shape.
Preferably, rubber pads are mounted at one end of each of the three clamping blocks.
Compared with the prior art, the beneficial effects of the utility model are that:
1. through the cooperation between the three springs and the positioning pin, the springs control the movement of the positioning block, so that workpieces with different outer diameters are fixed, the centering purpose is realized, and the condition that the part processing is deviated due to deviation of the part placing position is prevented;
2. the three adjusting screws are matched with the clamping blocks, and the parts are clamped and fixed according to different radiuses of the parts, so that the purpose of clamping the workpieces is achieved, and the situation that the machining positions are not aligned and the parts are lost due to deviation in clamping is prevented;
to sum up, the utility model discloses having reached and having used big excircle center as the purpose of benchmark throughout, having avoided repeated positioning, the staff needs the frequent adjustment part, hinders the process time, reduces machining efficiency's problem, and is firm to parts machining simultaneously, guarantees that the deviation appears in parts machining position, leads to the condition emergence of part damage.
