Abstract
The utility model relates to a tooling clamp for revolving workpiece manufacture, in particular to a tapered mandrel dismounting device which comprises a mandrel, wherein a conical surface is formed on the mandrel; the mandrel positioned outside a small end of the internal diameter of the conical surface is sheathed with a gasket; the gasket is fixed through a hexagonal nut in a tightening manner; a plane bearing is installed on the mandrel positioned outside a big end of the internal diameter of the conical surface; and the plane bearing is fixed through a round nut. The tapered mandrel dismounting device can be utilized to take down a workpiece fast and conveniently, and strain or impact on the surface of the workpiece can be avoided; and in addition, the tapered mandrel dismounting device is simple and reliable, convenient to use, low manufacturing cost, and easy to maintain.
Description
Technical field
The utility model relates to the frock clamp of rotary work piece processing, is specially the tapering core shaft dismantling device.
Background technology
During tapering disassembling mandrel workpiece, due to will be with Work-sheet pressing in the preorder process, workpiece contacts with the mandrel conical surface, and contact-making surface generally all requires more than 80%, and this just causes workpiece dismounting after processing difficult.
Present technology generally adopt copper rod to knock the workpiece lower surface or below the mandrel tapering one section screw thread of car, utilize nut that workpiece is ejected.The method of knocking with copper rod easily causes damaging of workpiece, and easily causes pulling of surface of the work with the method for nut.
Summary of the invention
The utility model provides a kind of tapering core shaft dismantling device for the problems referred to above, adopts this device can take off easily workpiece, the situation of avoiding simultaneously surface of the work to pull or damage.
According to the technical solution of the utility model: the tapering core shaft dismantling device is characterized in that: comprise mandrel, described mandrel is provided with the conical surface, is set with packing ring on the outside mandrel of described conical surface internal diameter small end, and described packing ring is tightened fixing by hex nut; Mounting plane bearing on the outside mandrel of the large end of described conical surface internal diameter, described plane bearing is fixed by round nut.
Technique effect of the present utility model is: use the utility model to take off quickly and easily workpiece, avoid pulling or damaging of surface of the work; The utility model is simple and reliable, and is easy to use, and cost of manufacture is low, is easy to safeguard.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further described.
In Fig. 1, comprise mandrel 1, plane bearing 2, round nut 3, packing ring 4, hex nut 5, the conical surface 6 etc.
As shown in Figure 1, the utility model is a kind of tapering core shaft dismantling device, comprises mandrel 1, and described mandrel 1 is provided with the conical surface 6, suit packing ring 4 on the outside mandrel 1 of the described conical surface 6 internal diameter small ends, and described packing ring 4 is tightened fixing by hex nut 5; Mounting plane bearing 2 on the outside mandrel 1 of the described conical surface 6 large ends of internal diameter, described plane bearing 2 is fixing by round nut 3.
The course of work of the present utility model is as follows: with workpiece to be processed and mandrel 1 wiped clean, with the workpiece mandrel 1 of packing into, the gap of 2-3mm is arranged between workpiece and plane bearing, cover upper gasket 4, with hex nut 5 with Work-sheet pressing.After the workpiece process finishing, back out hex nut 5, take off packing ring 4, upwards turn round nut 3, round nut 3 upward forces are acted on plane bearing 2, make upwards power be evenly distributed in the surface of workpiece by plane bearing 2, and plane and not slip of workpiece on plane bearing 2, thereby can not scratch surface of the work.Thereby prevent that effectively workpiece from damaging and pull on the surface.
Use the utility model to take off quickly and easily workpiece, avoid pulling or damaging of surface of the work; The utility model is simple and reliable, and is easy to use, and cost of manufacture is low, is easy to safeguard.
