Abstract
The utility model discloses an automatic positioning frame, which comprises a three-jaw chuck, a gear connecting rod, a gear, a spur rack and an adjustable air cylinder, wherein the adjustable air cylinder is fixed on the top of the spur rack, the bottom of the spur rack is engaged with the gear, the gear is connected with the three-jaw chuck through the gear connecting rod, one side of the three-jaw chuck is provided with chuck jaws, the inner side of each chuck jaw is provided with a bearing, one side of the spur rack, which is away from sawteeth is provided with a scale layer, and the adjustable air cylinder is provided with an oil box. The automatic positioning frame is simple in structure, convenient and practical, capable of guaranteeing the concentricity of a product in machining to reach 0.02mm and also capable of adjusting the distance of a bearing, so that the automatic positioning frame can be applied to the products with different diameters; and the automatic positioning frame is provided with the oil box, so that the gear and the spur rack can be lubricated, the automatic positioning frame can be better maintained, and the service life can be prolonged.
Description
Technical field
The utility model belongs to the mechanical processing and positioning field, is specifically related to a kind of automatic positioning frame.
Background technology
Lathe is the important working equipment of mechanical field at present, and the lathe kind is many, there are some specially elongated round condition to be done Surface Machining, comprise instrument lathe, automatic instrument lathe and CNC automatic turning machine etc., this class lathe locating rack that uses now all is more common to the fixing of product, cause in process, product is because rotation has a centrifugal action, product can rock, cause concentricity larger, affect product quality, and these lathes all can only process the product of fixed diameter, application is very little.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, provides a kind of concentricity little, the lathe locating rack that the product diameter range of processing is larger.
The technical scheme that the utility model adopts is: a kind of automatic positioning frame, comprise scroll chuck, gear connecting rod, gear, spur rack, adjustable cylinder, adjustable cylinder is fixed on the top of spur rack, the bottom of spur rack and gear engagement, gear is connected with scroll chuck by gear connecting rod, and a side of described scroll chuck is equipped with chuck jaw, and bearing is equipped with in the inboard of chuck jaw, described spur rack is provided with one deck scale layer away from a side of sawtooth, and described adjustable cylinder is provided with an oil box.
As preferably, described scroll chuck is pneumatic scroll chuck or hydraulic pressure scroll chuck.
The beneficial effects of the utility model are: the utility model is simple in structure, convenient and practical, can guarantee that product adds the concentricity in man-hour and reaches in 0.02 millimeter, and can regulate the spacing of bearing, so that can be applied on the product of multiple different-diameter; Be provided with the scale layer, be convenient to when processing same class product, adjust to fast same clamping position, with oil box, can be oily to gear, spur rack etc. at any time, so that the utility model is better maintained, prolong its service life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, scroll chuck; 2, bearing; 3, chuck jaw; 4, gear connecting rod; 5, gear; 6, spur rack; 7, adjustable cylinder; 8, scale layer; 9, oil box.
The specific embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
Embodiment: as shown in Figure 1, the utility model comprises scroll chuck 1, gear connecting rod 4, gear 5, spur rack 6, adjustable cylinder 7, adjustable cylinder 7 is fixed on the top of spur rack 6, the bottom of spur rack 6 and gear 5 engagements, gear 5 is connected with scroll chuck 1 by gear connecting rod 4, and a side of described scroll chuck 1 is equipped with chuck jaw 3, and bearing 2 is equipped with in the inboard of chuck jaw 3, described spur rack 6 is provided with one deck scale layer 8 away from a side of sawtooth, and described adjustable cylinder 7 is provided with an oil box 9; Described scroll chuck 1 is pneumatic scroll chuck 1 or hydraulic pressure scroll chuck 1.
During use, when adjustable cylinder 7 was supplied with air pressure by air pump, adjustable cylinder 7 pressed down, and drove spur rack 6 and moved down, and by engagement, driven gear 5 rotates, and gear connecting rod 4 also rotates simultaneously, thus the spacing between control scroll chuck 1 upper bearing (metal) 2.
