Abstract
The utility model discloses a conical thermal-expansion correcting fixture, and aims to realize zero-clearance fit when being assembled with a corrected thin-wall cylinder and improve thermal-expansion correcting quality. The conical thermal-expansion correcting fixture comprises a split cone, a conical expansion member, a limit plate and a tension nut. The split cone is split at the front-end cone flaps, and the rear end is integrated. The cone faces of the split cone and conical expansion member are matched at consistent cone angle. A screw is arranged on the conical expansion member, a through hole is formed in the limit plate, and the screw penetrates the through hole to connect to the tension nut in a screwed manner.
Description
Technical field
The utility model relates to a kind of heat expansion school shape mold, particularly a kind of taper heat expansion school shape mold of thin cylinder.
Background technology
The high thin cylinder of required precision in adding process, moulding or machine is needed to correct shape, as to needing to correct shape after thin cylinder rotary press modelling, after the outer suspension member of thin cylinder welding, because existing part to stay at weld, welding stress also needs school shape, at present the domestic heat expansion method that generally adopts is corrected shape thin cylinder, what heat expansion method school shape generally adopted is straight tube shape heat expansion school shape mold, its shortcoming is: while assembling because of straight tube shape heat expansion mold with by school shape cylindrical shell, will guarantee matched in clearance, if gap is too small, assembling difficulty, if strengthen gap, sizing precision declines, and then affect heat expansion school form quality amount.
Summary of the invention
Technical problem to be solved in the utility model: solve the problem of sizing precision decline of the too small assembling difficulty in shape mold assembled gap, current straight tube shape heat expansion school and excesssive gap, provide a kind of and can realize the taper heat expansion school shape mold that zero clearance coordinates when being assembled by school shape thin cylinder.
For solving the technical problem existing, the technical solution adopted in the utility model is: taper heat expansion school shape mold comprises distinguish cone, tapered expansion body, position-arresting disk, tightening nut, distinguish cone adopts front-end-cone lobe place separately, rear end is an entirety, the conical surface of distinguish cone and the conical surface of tapered expansion body cooperatively interact and angle of taper consistent size, tapered expansion body is provided with screw rod, and position-arresting disk is provided with through hole, and screw rod is threaded with tightening nut through through hole.Described screw rod end face is provided with the structure of tetragonal body; Described distinguish cone material selection mild steel; The large stainless steel materials of thermal coefficient of expansion such as described tapered expansion body material selection 1Cr18Ni9Ti or 1Cr18Ni9 or 0Cr18Ni9Ti; Described tightening nut is because being used in conjunction with tapered expansion body screw rod, and tightening nut material, tapered expansion body material are consistent with screw rod material.
The installation step of using taper heat expansion school shape mold to carry out heat expansion school shape to thin cylinder is: after distinguish cone and tapered expansion body cone match, be placed in the endoporus of thin cylinder, and then position-arresting disk is inserted after the screw rod of tapered expansion body and with tightening nut tension, to make distinguish cone synchronously strut the interior bowlder that all contacts thin cylinder when distinguish cone cone lobe cylindrical to have completed assembling, now just can realize the zero clearance of taper heat expansion school shape mold when by school shape Assembly of the parts and coordinate requirement.
Beneficial effect of the present invention: the present invention has simple in structure, easy to operate, assembling and the high feature of heat expansion sizing precision, utilize the relative motion of two conical surface bodies to make distinguish bore the principle radially simultaneously strutting and realize school, heat expansion school shape, met the matching requirements of zero clearance, heat expansion school form quality amount improves.
accompanying drawing explanation
Fig. 1 is the topology view of taper heat expansion school shape mold, wherein, comprises distinguish cone 1, tapered expansion body 2, position-arresting disk 3, tightening nut 4, thin cylinder 5, screw rod 6;
Fig. 2 is the topology view of distinguish cone 1;
Fig. 3 is the topology view of tapered expansion body 2.
the specific embodiment
Below in conjunction with drawings and Examples, the present invention will be further described:
Shown in Fig. 1, taper heat expansion school shape mold comprises distinguish cone 1, tapered expansion body 2, position-arresting disk 3, tightening nut 4, distinguish cone 1 adopts front-end-cone lobe place separately, rear end is an entirety, the conical surface of distinguish cone 1 and the conical surface of tapered expansion body 2 cooperatively interact and angle of taper consistent size, tapered expansion body 2 is provided with screw rod 6, and position-arresting disk 3 is provided with through hole, and screw rod 6 is threaded with tightening nut 4 through through hole.Described screw rod 6 end faces are provided with the structure of tetragonal body; Described distinguish is bored 1 material selection mild steel; The large stainless steel materials of thermal coefficient of expansion such as described tapered expansion body 2 material selection 1Cr18Ni9Ti or 1Cr18Ni9 or 0Cr18Ni9Ti; Described tightening nut 4 materials, tapered expansion body 2 materials are consistent with screw rod 6 materials.
The installation step of using taper heat expansion school shape mold to carry out heat expansion school shape to thin cylinder 5 is: after distinguish cone 1 and tapered expansion body 2 cone match, be placed in the endoporus of thin cylinder 5, and then position-arresting disk 3 is inserted to the screw rod 6 of tapered expansion body 2 is rear synchronously struts distinguish cone 1 with tightening nut 4 tensions, the interior bowlder that all contacts thin cylinder 5 when distinguish cone 1 cone lobe cylindrical has completed assembling, and the zero clearance in the time of now just can realizing taper heat expansion school shape mold and assemble with thin cylinder coordinates requirement.
