Abstract
The utility model relates to a spring-pressure-adjustable large workpiece overload turnplate elastic positioner, which comprises a seat cover 12, a guide rod 3 and a spring 2. The upper and lower ends of the seat cover are provided with front and rear end caps 9, 1. The guide rod is in the form of a ball-head type guide rod, and the head part of the guide rod is provided with a ball head. The middle part of the guide rod is provided with a positioning step 7 for limiting the stroke of the guide rod. The tail part of the guide rod is in the form of a cylindrical rod body and the spring can be sleeved onto the cylindrical rod body. The elastic positioner is characterized in that the rear end cap 1 is provided with an adjusting screw 15. The tail part of the spring 2 is provided with a concave cover type pressing sleeve 13. The tail part of the spring 2 is directly arranged in the concave cover body of the pressing sleeve 13. The spring force of the spring 2 is adjusted through the pressing sleeve 13 by means of an adjusting screw 15. The spring-pressure-adjustable large workpiece overload turnplate elastic positioned is simple in structure, adjustable in spring pressure, quick in positioning effect and high in efficiency. Meanwhile, when the spring is driven to frequently stretch out and draw back, the spring is well protected by the concave cover type pressing sleeve 13. Therefore, the spring is more secure and more reliable.
Description
Technical field
The utility model relates to the elastic positioning device that heavy-load manual in paint line is determined the adjustable large workpiece heavy duty rotating disk of manual turntable, particularly a kind of spring pressure that angle send part to reprint.
Background technology
For the large workpiece such as automobile, in the technical process such as its spraying, need to be placed on and on manual turntable, carry out calibration processing.For the automobile of different loading capacity, the weight of its car body is up to 2-4 ton left and right, so high especially for the requirement of the index table rotating disk using in process.Due to workpiece volume and loading capacity large, the inertia force of workbench when calibration rotates is just very large, so very high to the requirement of the anti-shear ability of workbench elastic device and stability.
At present, most workpiece indexing rotary table, all adopts steel-ball type spring-positioning device, also adopts steel ball as keeper, steel ball, Compress Spring and abutment sleeve three parts, consists of.The abutment sleeve in steel ball and spring outside is generally formed by light-wall pipe swaging location, location.This structure, light, flexible owing to rotating, thus be generally only applicable to underloading workpiece, and for the heavy load workpiece of large volume, but far from applicable, have very large defect.Because the machining accuracy of the shape rotating disk locating surface of attaching most importance to is not high, between support member and locating surface, must there is larger gap, must make the size of steel ball protrusion abutment sleeve larger, thereby guarantee space, location.But do so the inevitable diameter that greatly increases steel ball, also add big spring and outside abutment sleeve thereof simultaneously.Must seriously increase the weight of steel ball positioner like this, greatly dwindle its scope of application, inapplicable for the disk location that load-carrying is larger.Moreover, steel ball spring positioner, because the anti-shear ability of steel ball is low, positioning stablity performance is poor, and guide effect is not good, therefore, is unsuitable for being applied in large workpiece heavy duty rotating disk.Particularly, the pressure of its spring is non-adjustable, uses after a period of time, and spring force is lax, and its screen resilience declines, locate more unstable, even inefficacy.
Summary of the invention
Technical barrier to be solved in the utility model is, overcomes above-mentioned deficiency, and a kind of simple in structure, easy to use, positioning performance stable and spring pressure is adjustable large workpiece heavy duty rotating disk elastic positioning device is provided.
Technical solution of the present utility model is, comprises cover for seat 12, guide rod 3 and spring 2, and the two ends up and down of cover for seat 12 are provided with forward and backward end cap 9,1, and guide rod 3 and spring 2 are located in cover for seat 12, and spring 2 is placed on guide rod 3; Guide rod 3 is bulb type guide rod, and its head is provided with bulb, outside the drive end bearing bracket 9 of extended cover for seat 12; Middle part is provided with and can carries out spacing positioning step to stroke; Afterbody is the column type body of rod, and spring 2 is placed on the column type body of rod; It is characterized in that: rear end cap 1 is provided with adjustment screw 15, the afterbody of spring 2 is provided with spill cover type gland 13, and the afterbody of spring 2 is directly placed in the spill lid of gland 13, and the spring force by adjustment screw 15 by 13 pairs of springs 2 of gland regulates.
The utility model is fixed on rotary base 6 by pressing plate 10 and screw 4,11 by block set 12, is provided with and regulates pad 5 between pressing plate 10 and rotary base 6.
The utility model and prior art compare, and the advantage possessing is, simple in structure, spring pressure is adjustable, and location is fast, and efficiency is high; Location rod member positioning end adopts little bulb, and bulb rear side adopts cylinder guiding, and has increased positioning step, can control the location emersion limit of guide post, and the body diameter that rear portion dwindles is just as the guide post of Compress Spring; Adopt pressing plate and regulate pad series connection, and be connected by screw, make setting height(from bottom) of the present utility model adjustable.
