Abstract

The utility model relates to an automatic positioning frame. The positioning frame comprises a three jaw chuck (1), a gear connecting rod (4), a gear (5), a spur rack (6) and an adjustable cylinder (7), wherein the adjustable cylinder (7) is fixed at the top of the spur rack (6); the bottom of the spur rack (6) is meshed with the gear (5); the gear (5) is connected with the three jaw chuck (1) through the gear connecting rod (4); 3-6 chuck jaws (3) are mounted on one side of the three jaw chuck (1); 3 to 6 bearings (2) are mounted on the inner sides of the chuck jaws (3); the adjustable cylinder (7) presses down when supplied with an air pressure, so that the spur rack (6) is driven to move downwards and drive the gear (5) and the gear connecting rod (4) to rotate simultaneously, and the intervals among the bearings (2) on the three jaw chuck (1) can further be controlled; and the three jaw chuck (1) adopts an engine lathe three jaw chuck, a pneumatic three jaw chuck or a hydraulic three jaw chuck. The utility model has the benefits that the concentricity of products during processing can be controlled below 0.02 mm, and the intervals among the bearings are adjustable, so that the positioning frame is suitable for products with different diameters.

Description

Automatic locating rack
Technical field
A kind of equipment positioner that the utility model relates to especially relates to the positioner on a kind of lathe.
Background technology
Lathe is the important working equipment of mechanical field, 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., all be more common at this class lathe locating rack that uses to the fixing of product at present, cause in process, product is because rotation has a centrifugal action, product can rock, cause concentricity bigger, influence product quality, and the product that these lathes all can only the fixed processing diameter, application is very little.
Summary of the invention
It is little that the technical problems to be solved in the utility model provides a kind of concentricity, the lathe locating rack that the product processed diameter range is bigger.
To achieve these goals, the technical scheme that the invention is taked is: automatic locating rack, comprise scroll chuck, gear connecting rod, gear, spur rack, adjustable cylinder, adjustable cylinder is the top of spur rack fixedly, the bottom of spur rack and gears engaged, gear is connected with gear connecting rod with scroll chuck, one side of scroll chuck is equipped with chuck jaw, bearing is equipped with in the inboard of chuck jaw, when adjustable cylinder was supplied with air pressure by air pump, adjustable cylinder pressed down, and drove spur rack and moved down, by engagement, driven gear rotates, and gear connecting rod also rotates simultaneously, thus the spacing between the control scroll chuck upper bearing (metal), chuck jaw and bearing are 3 to 6 groups, and scroll chuck is the engine lathe scroll chuck, pneumatic scroll chuck or hydraulic pressure scroll chuck.
The beneficial effects of the utility model: can guarantee that product adds the concentricity in man-hour and reaches in 0.02 millimeter, and can regulate the spacing of bearing, make the product of multiple different-diameter.
Description of drawings
Fig. 1. main TV structure schematic diagram of the present utility model.
Fig. 2. main TV structure schematic diagram of the present utility model.
The specific embodiment
Automatic locating rack described in the utility model, concrete embodiment is as follows:
Fig. 1, shown in Figure 2, figure grade explanation: scroll chuck 1, bearing 2, chuck jaw 3, gear connecting rod 4, gear 5, spur rack 6, adjustable cylinder 7.
Automatic locating rack, comprise scroll chuck 1, gear connecting rod 4, gear 5, spur rack 6, adjustable cylinder 7, adjustable cylinder 7 is the top of spur rack 6 fixedly, the bottom of spur rack 6 and gear 5 engagements, gear 5 is connected with scroll chuck 1 usefulness gear connecting rod 4, one side of scroll chuck 1 is equipped with chuck jaw 3, bearing 2 is equipped with in the inboard of chuck jaw 3, when adjustable cylinder 7 is supplied with air pressure by air pump, adjustable cylinder 7 presses down, drive spur rack 6 and move down, by engagement, driven gear 5 rotates, gear connecting rod 4 also rotates simultaneously, thereby the spacing between control scroll chuck 1 upper bearing (metal) 2, chuck jaw 3 and bearing 2 are 3 to 6 groups, scroll chuck 1 is the engine lathe scroll chuck, pneumatic scroll chuck or hydraulic pressure scroll chuck.
