The problems such as clamping tooling of different parts is not general.
Summary of the invention
It in order to solve the problems existing in the prior art, is that part is made using tensioner principle the utility model proposes a kind of expander
A kind of clamping device being accurately positioned on axis is mainly used for the positioning and processing in hole, has structurally reasonable, positioning standard
Really, convenient disassembly, replacement speed is fast, the high feature of positioning accuracy, each ringfeder can realize difference zero in a certain range
The positioning and clamping in part hole, can also be by the ringfeder further expansion use scope of replacement different size, and practical is a kind of positioning
Clamping tool.
The technical solution of the utility model are as follows:
A kind of expander, it is characterised in that: be made of mandrel, ringfeder, screw rod, gasket and bolt；
The mandrel main body be with tapered long frustum cone structure, the taper and dividing head spindle or lathe of mandrel main body or
The taper corresponding matching in the spindle taper hole on grinding machine；The miner diameter end of the mandrel main body is provided with central axial tapped blind hole, axis
It is overlapped to the central axis of tapped blind hole with the central axis of mandrel main body；Axial thread blind hole can match with screw rod and gasket
It closes, expander is fixed on process equipment；
The bigger diameter end center of the mandrel has axial conicle protrusion, the central axis and mandrel of axial conicle protrusion
Central axis is overlapped, and the taper of axial conicle protrusion is matched with the taper inside ringfeder；It opens axial conicle protrusion end face
There is central axial tapped blind hole, the central axis of axial thread blind hole is overlapped with the central axis of axial conicle protrusion；
After taper hole is with axial conicle male cooperation inside ringfeder, the hole in parts to be processed is matched with ringfeder outer circle
It closes, then bolt is screwed into the axial thread blind hole of axial conicle protrusion end face, make hole in piece part tensioner, reach locating element
Purpose.
Further preferred embodiment, a kind of expander, it is characterised in that: the ringfeder with several various outer diameter sizes,
The internal taper of all ringfeders is identical.
Beneficial effect
1. the design is cooperated by ringfeder and mandrel, play the role of tensioner inner bore of part, convenient for mounting and clamping, positioning is reliable；
2. ringfeder and mandrel are independent mutually, when on part hole it is not of uniform size when, only need to change the ringfeder of identical size
, no replacement is required mandrel both provided convenience for the processing of part, the use scope of clamp fixture also made to have obtained effective expansion
Greatly；
3. the positioning accuracy of part greatly improves by being used cooperatively for mandrel and ringfeder, deformation reduces, make part plus
Working medium amount is obviously improved.
The additional aspect and advantage of the utility model will be set forth in part in the description, partially will be from following description
In become obvious, or recognized by the practice of the utility model.

Specific embodiment
The embodiments of the present invention are described below in detail, the embodiment is exemplary, it is intended to for explaining this reality
With novel, and should not be understood as limiting the present invention.
In the description of the present invention, it should be understood that term " center ", " longitudinal direction ", " transverse direction ", " length ", " width
Degree ", " thickness ", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside",
The orientation or positional relationship of the instructions such as " clockwise ", " counterclockwise " be based on the orientation or positional relationship shown in the drawings, be only for
Convenient for description the utility model and simplify description, rather than the device or element of indication or suggestion meaning must have specifically
Orientation is constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.
As shown in Figure 3 and Figure 4, the utility model proposes a kind of expanders, by mandrel, ringfeder, screw rod, gasket and bolt group
At.
The mandrel main body is with tapered long frustum cone structure, and the taper of mandrel main body is Tong Yongmoshi taper, can be with
The taper corresponding matching in the spindle taper hole on dividing head spindle or lathe or grinding machine realizes that the part under different operating conditions adds
Work.
The miner diameter end of the mandrel main body is provided with central axial tapped blind hole, the central axis and mandrel of axial thread blind hole
The central axis of main body is overlapped；Axial thread blind hole can cooperate with screw rod and gasket, and expander is fixed on process equipment,
To make part realize clamping.
The bigger diameter end center of the mandrel has axial conicle protrusion, the central axis and mandrel of axial conicle protrusion
Central axis is overlapped, and the taper of axial conicle protrusion is matched with the taper inside ringfeder；It opens axial conicle protrusion end face
There is central axial tapped blind hole, the central axis of axial thread blind hole is overlapped with the central axis of axial conicle protrusion；When rising
After covering internal taper hole and axial conicle male cooperation, the hole in parts to be processed is cooperated with ringfeder outer circle, then bolt is twisted
In the axial thread blind hole for entering axial conicle protrusion end face, bolt is tightened, makes ringfeder expanding distortion, so that hole in piece part be risen
Tightly, achieve the purpose that locating element.Due to a series of ringfeder with various outer diameter sizes, the internal taper phase of all ringfeders
Together, so if hole in piece part it is not of uniform size when, only need to change the ringfeder of size identical as hole size.
The utility model realizes the clamping of part using the relative motion between mandrel and ringfeder, and part is enable to make
It is positioned when making, is provided a great convenience for processing well.The utility model mandrel main body can with dividing head spindle or
The cooperation of the spindle taper hole of lathe or grinding machine, can access good application on plain-milling machine and numerical control device.This is practical
Novel clamping is convenient and reliable, can save a large amount of process time, and the practicality is high, and economic performance is good, and replacement speed is fast, positioning accurate
Degree is accurate, it can be achieved that use of the different parts on same sleeve clamp adds with certain popularity covering class and needing to index
There can be certain economy at seriation in the manufacturing process of work part, can promote the use of in a certain range.
Although the embodiments of the present invention have been shown and described above, it is to be understood that above-described embodiment is
