Abstract
The utility model discloses a frame internal diameter processing footing location frock, including square backing plate square backing plate is the multilayer, wherein the square backing plate of lower floor through square backing plate locating pin and T type nut, stud and nut positioning on machine tool table, locating pin between set plate between square backing plate, still set up protruding type groove and keyway on the square backing plate, the square backing plate and the work piece of the superiors are fixed with thin nut and work piece locating pin through the locking bolt that protruding type inslot set up within a definite time. The utility model discloses an advantage: 1. Once but secondary dress card and alignment time have been saved to tang terminal surface and internal diameter around the dress card simultaneous processing, 2. Because dress card form is a frame axis parallel placement, so made things convenient for measurement internal diameter size, 3. Loaded down with trivial details degree when having reduced the dress card, 4. The frame footing board that just compresses tightly so there is not the circumstances of packing force bounce -back, has been avoided unclamping the circumstances that the clamp plate frame is out of shape after the processing because the clamp plate compresses tightly and leads to the fact.
Description
Technical field
The utility model relates to mechanical field, is a kind of processing tool of support internal diameter specifically.
Background technology
When processing internal diameter (the φ A of Fig. 1 and φ B) of support, the method that prior art adopts adopts vertical Vehicle Processing internal diameter and seam, the mode of being installed of support is that one end seam faces down, and is pressed in firmly on chuck by support after centering with pressing plate, processing other end internal diameter and seam end face.Due to the restriction by lathe cutter saddle stroke and measuring position, often need secondary to be installed and just can machine all internal diameters and seam.Unclamping pressing plate upset support, by processing footpath again after centering, again fastening workpiece, processing opposite side internal diameter and seam end face.This processing mode, to ensure the axiality requirement of seam before and after support, takes much time with regard to needs and carries out centering.Simultaneously because support belongs to welding structural element, itself there is internal stress to exist, to rebound the distortion brought to prevent from processing rear support stress.So the thrust when fastening with pressing plate is not easily excessive.Again due to need pressing plate, double threaded screw, T-nut, cushion block etc. be used when pressing plate is installed, loaded down with trivial details especially when being installed.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of support internal diameter processing footing positioning tool, changes frame manufacture mode and the form that is installed; Adopt support ground instep and four installing hole mounts, with seam end face and internal diameter before and after single head boring processing support, the concrete structure of the frock adopted is:
A kind of support internal diameter processing footing positioning tool, comprises alignment pin between square backing plate, plate, stud, nut, locking nut, Workpiece fixing pin, thin nut; Described square backing plate is multilayer, and wherein undermost square backing plate is positioned on platen by square backing plate alignment pin and T-nut, stud and nut; Between described square backing plate, alignment pin between plate is set; Square backing plate also arranges concave slot and keyway, is fixed by the clamping screw that arranges in concave slot and thin nut and Workpiece fixing pin between the square backing plate of the superiors and workpiece.
Advantage of the present utility model: 1. be once installed and can process front and back seam end face and internal diameter simultaneously, saves secondary and is installed and alignment time; 2. because the form of being installed is that support axis being parallel is placed, so facilitate measurement internal diameter size; 3., when being installed, only having used four nuts to compress support footing piece, reduced fussy degree when being installed; 4. the support footing piece just compressed, so the situation that there is not thrust bounce-back, avoids and causes because pressing plate compresses, unclamp the situation of pressing plate frame deformation after processing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Illustrate the utility model below in conjunction with accompanying drawing, as shown in Figure 1, the utility model comprises alignment pin 2, stud 3, nut 4, locking nut 6, Workpiece fixing pin 7, thin nut 8 between square backing plate 1, plate; Described square backing plate 1 is multilayer, and wherein undermost square backing plate 1 is positioned on platen 9 by square backing plate alignment pin 11 and T-nut 10, stud 3 and nut 4; 2 alignment pins between plate are set between described square backing plate 1; Square backing plate 1 also arranges concave slot and keyway, and the clamping screw 6 by arranging in concave slot between the square backing plate 1 of the superiors and workpiece 5 is fixed with thin nut 8 and Workpiece fixing pin 7.
It is square backing plate 1 orlop one and platen 9 are located by square backing plate alignment pin 11 that the present embodiment adds man-hour, and locate with alignment pin between plate 2 between square backing plate 1, select pad how many square backing plates 1 according to the center high size of the electric machine stand of processing different size; Then Workpiece fixing pin 7. and thin nut 8 are assembled on the square backing plate of the superiors.By stud 3, nut 4, T-nut 10, square backing plate 1 is pressed on platen 9 firmly again, and workpiece (electric machine stand) 5 is located by Workpiece fixing pin 7, is finally compressed by electric machine stand 5 with locking nut 6; Now just can with the single head boring processing φ A. φ B uniform internal diameter of electric machine stand and seam.
