Summary of the invention
The object of the invention is to overcome the shortcoming existing in prior art, a kind of special fixture that rear-bank rotor housing is stressed more evenly, clamping precision is higher that clamps is provided, the technical scheme adopting is: a kind of Thin Wall Cylinder Blocks size special fixture, comprise the clamp body being fixedly connected on lathe, described clamp body has male cone (strobilus masculinus), it is characterized in that: described special fixture also comprises: clamp drive part, described clamping drive part comprises can complete axially movable pull bar; The part that is fixedly clamped, described in the part that is fixedly clamped comprise the spring that rises, described in the spring that rises there is the inner conical surface coordinating with the male cone (strobilus masculinus) of described clamp body, the outer ring surface of the spring that rises coordinates with Thin Wall Cylinder Blocks inner surface; Localization part, described localization part comprises positioning disk, and positioning disk one end is fixed on described clamp body, and the other end coordinates with Thin Wall Cylinder Blocks end face as locating surface; Targeting part, described targeting part comprises spigot nut and the pulling plate being fixed on described pull bar, described pulling plate and spigot nut fix.
Technical characterictic of the present invention also has: described clamping drive part also comprises pull bar support set, and described pull bar is installed in the endoporus of described pull bar support set.
Technical characterictic of the present invention also has: described in the spring that rises by 8 above lobes that rise, formed.
Technical characterictic of the present invention also has: described in the spring that rises by 10 lobes that rise, formed.
Technical characterictic of the present invention also has: described in the spring that rises by 20 lobes that rise, formed.
Beneficial effect of the present invention is: this fixture is by the spring tensioner workpiece that rises, the contact area that the design of a plurality of lobes that rise has increased workpiece and risen between lobe, thus workpiece force and deformation is more even; The possibility of fixture circular runout has been eliminated in the use of targeting part, makes workpiece obtain better crudy.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention, and accompanying drawing 2 is A-A views of accompanying drawing 1, wherein, the 1st, pull bar, the 2nd, lathe terminal pad, the 3rd, clamp body, the 4th, pull bar support set, the 5th, the spring that rises, the 6th, workpiece, the 7th, spigot nut, the 8th, pulling plate, the 9th, the lobe that rises, the 10th, positioning disk.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.The invention discloses a kind of Thin Wall Cylinder Blocks size special fixture, the rise change on spring structure and the targeting part of setting up of this fixture overcome the poor defect of clamping positioning precision in conventional art, thereby guaranteed crudy.Concrete structure is: this fixture comprises clamp body 3, clamps drive part, localization part and targeting part, wherein clamp body 3 is bolted to connection on the lathe terminal pad 2 of lathe, clamp body 3 has male cone (strobilus masculinus), and the inside of clamp body 3 has hole, and pull bar 1 is installed in hole.Clamp drive part and be included in the lower axially movable pull bar 1 of lathe clamping cylinder drive and pull bar support set 4, the two ends of pull bar 1 are all processed with screw thread, and pull bar 1 is housed in the endoporus of pull bar support set 4, can increase the support force of pull bar 1.The part that is fixedly clamped comprises the spring 5 that rises, and the spring 5 that rises has the inner conical surface coordinating with clamp body 3 male cone (strobilus masculinus)s, and the outer ring surface of the spring 5 that rises coordinates with workpiece 6 inner surfaces to be processed.Localization part comprises the positioning disk 10 that one end is fixedly connected with clamp body by bolt, and the other end coordinates with workpiece 6 as locating surface.Targeting part comprises spigot nut 7 and the pulling plate 8 being threaded on pull bar 1, and the guiding cylindrical of spigot nut 7 and pulling plate 8 are bolted and are integrated.The guiding cylindrical of spigot nut 7 and the little matched in clearance of clamp body 3 endoporus, in hole slidably.
