Abstract
The utility model provides an adjustable mandrel is including the mandrel body, cushion and end cap. Mandrel body back end is provided with open -ended cavity backward, and the external wall circular arrangement of mandrel that the cavity corresponds is provided with cell body three and the cavity intercommunication, is provided with the cushion in the cell body, and the cushion inboard is provided with the tapering district, and attentive axis body rearmost end is that the cavity rear end is provided with the end cap, end cap and mandrel body threaded connection, and the end cap front end be the toper, tapering phase -match that the conical tapering of end cap front end and cushion tapering were distinguished. An adjustable mandrel, overall structure is simple, operation convenient to use, stability is good, the reliability is high, uses an adjustable mandrel, not only processing is simple, the clamping freedom, can change the cushion according to the big or small range adjustment of part hole moreover, is of value to very much and uses widely.
Description
Technical field
The utility model relates to field of machining, particularly relates to a kind of expansion mandrel.
Background technology
In field of machining, in order to process sleeve workpiece, generally to install at the axial centerline of sleeve workpiece and fixing a single mandrel, there is difficult processing in traditional expanding arbor, Heat Treatment Control is difficult, and the problem that precision cannot ensure, therefore needs a kind of novel axle to solve the problems referred to above.
Utility model content
The utility model object is, overcomes the deficiencies in the prior art part, provides that a kind of processing is simple, clamping freely, and can change the expansion mandrel of cushion block according to the magnitude range adjustment of inner bore of part.
A kind of expansion mandrel described in the utility model, includes spindle body, cushion block and plug.Spindle body is the main element of a kind of expansion mandrel described in the utility model, described spindle body back segment is provided with aft-opening cavity, the spindle body outer wall circumferential arrangement that cavity is corresponding be provided with three with the cell body of cavity connects, cushion block is provided with in described cell body, tapering district is provided with inside cushion block, spindle body rearmost end and cavity rear end are provided with plug, described plug is threaded with spindle body, plug front end is taper, and the tapering of described plug front end taper and the tapering in cushion block tapering district match.When in use, due to the tapering of plug front end and the taper fit of cushion block, when screw-in plug, cushion block can progressively promote, until closely cooperate with part, to part location, is convenient to processing.
A kind of expansion mandrel described in the utility model, overall structure is simple, easy for operation, good stability, reliability is high, uses a kind of expansion mandrel described in the utility model, and not only processing is simple, clamping is free, and cushion block can be changed according to the magnitude range adjustment of inner bore of part, be a significant benefit to and promote the use of.
