Abstract
The invention discloses a hollow roller grinding and positioning tool. The hollow roller grinding and positioning tool comprises a mandrel, fastening sleeves, positioning cones and a positioning sleeve, wherein threads are arranged at the two ends of the mandrel; the fastening sleeves are respectively mounted at the two ends of the mandrel through threaded connection; the positioning cones are arranged in the fastening sleeves; the fastening sleeves and the positioning cones are fixedly connected through fastening screws; the positioning cones respectively coat the two ends of the mandrel; elastic sleeves are respectively arranged on the positioning cones, and have inner conical surfaces fitting conical surfaces of the positioning cones; and the positioning sleeves are respectively arranged on the elastic sleeves. The hollow roller grinding and positioning tool not only can guarantee the grinding quality of hollow rollers, but also can greatly improve the grinding efficiency of the hollow rollers.
Description
Technical field
The present invention relates to field of machining, particularly a kind of auxiliary locating tool equipment for hollow roll grinding.
Background technology
Hollow roll is often seen in production in light industry, printed matter as food packing machine, medicine packaging machinery, trade mark production line and the overwhelming majority all will use hollow roll in producing, it is mainly used in conducting the slim materials such as such as aluminium foil, plastics, film or paper, in order to ensure the precision of conducting, this just requires that the surface smoothness of hollow roll must be high.In the past when carrying out grinding to hollow roll roll body surface, hollow roll both sides dead eye own is normally utilized to have comparatively high-axiality, adopt mandrel and the dead eye of location cone to hollow roll both sides to locate simultaneously, but because location cone linearly contacts with hollow roll roll body, contact area is little, location is not very accurate, causes grinding accuracy not reach requirement.
Summary of the invention
The invention solves original positioning tool locating surface little, the problem of grinding accuracy cannot be ensured, provide a kind of easy to use, can increase work efficiency and the hollow roll grinding positioning tool of grinding accuracy.
For solving the problems of the technologies described above, present invention employs a kind of hollow roll grinding positioning tool, comprise mandrel, sleeve, location cone and positioning sleeve, described mandrel two ends are provided with screw thread, described sleeve is threaded connection the two ends being arranged on mandrel respectively, location cone is provided with in described sleeve, be fixed by holding screw between described sleeve with location cone and be connected, described location cone is enclosed within the two ends of mandrel respectively, described location cone is provided with a resilient sleeve, described resilient sleeve has the inner conical surface matched with the conical surface of location cone, described positioning sleeve is separately positioned on resilient sleeve.
In the present invention, described resilient sleeve is circumferentially provided with multiple open slot in the axial direction.
In the present invention, further, described open slot one end is provided with transitional pore.
The present invention, by arranging a resilient sleeve in the middle of location cone and hollow roll, adds location cone and acts on location area on hollow roll roll body, thus make the location of grinding process hollow core roller more stable, effectively improve the grinding accuracy of hollow roll; Frock adopts the mode of symmetrical clamping, and clamping and dismounting only need to turn symmetrically arranged sleeve, can workpiece loading and unloading easily, thus substantially increases operating efficiency.
