Abstract
The utility model provides a kind of special-shaped part vehicle hole fixture, including chuck body, vee-block is fixed on the end face of the chuck body, the inclined-plane of vee-block is equipped with the step of protrusion, and the end face of chuck body is equipped with the jacking mechanism and limited block opposite with the opening of vee-block.The utility model is positioned by double V-arrangements and axially slidable formula guiding mechanism, limits the degree of freedom of the part, ensures that accurate positioning, rapid clamping compress reliable.It compresses point and avoids machined surface and cutter, it is compact-sized.Overcome influence of the casting appearance and size deviation to positioning and processing, improves working efficiency and processing quality, reduce processing cost.
Description
Technical field
The present invention relates to a kind of technical field of special-shaped mo(u)lded piece lathe car hole machined, especially a kind of special-shaped parts
Vehicle hole fixture.
Background technology
Existing cast steel parts are polymorphic structure, are made of different arc-shaped of two arc radius.Both ends outside diameter
It is of different sizes.The size and screw thread and the accuracy of form and position of hole in piece part are more demanding, with the direct positioning and clamping of chuck on lathe, because
The influence repetitive positioning accuracy of blank error is not high, and clamping centering is time-consuming and laborious.Large batch of production is not adapted to, it cannot be guaranteed that
Processing quality is stablized.
Invention content
The purpose of this utility model is to provide a kind of special-shaped part vehicle hole fixture, disclosure satisfy that steel-casting of different shapes
Demand.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is as follows：A kind of special-shaped part vehicle hole fixture, packet
Include chuck body, it is characterised in that：Vee-block is fixed on the end face of the chuck body, the inclined-plane of vee-block is equipped with protrusion
The end face of step, chuck body is equipped with the jacking mechanism and limited block opposite with the opening of vee-block.
A kind of special-shaped part vehicle hole according to claim 1 fixture, it is characterised in that：The end face of the chuck body
It is equipped with Workpiece clamping slot, the both sides of Workpiece clamping slot are equipped with the axially slidable formula guiding mechanism with spring top clamping.
Advantageous effect：
The utility model is positioned by double V-arrangements and axially slidable formula guiding mechanism, limits the degree of freedom of the part, ensures
Accurate positioning, rapid clamping compress reliable.It compresses point and avoids machined surface and cutter, it is compact-sized.Overcome casting appearance and size inclined
Influence of the difference to positioning and processing improves working efficiency and processing quality, reduces processing cost.
Description of the drawings

Fig. 2 is double V-shaped vee-block schematic diagram.
Fig. 3 is the faces the B-B sectional view of Fig. 2.
Fig. 4 is the faces the A-A sectional view of Fig. 1.
Specific implementation mode
As shown in figure Fig. 1, Fig. 2, Fig. 3, Fig. 4, it is as follows to further describe the utility model：A kind of shaped piece vehicle hole fixture,
Including chuck body 1, the vee-block 2 of fixed double V-arrangements, jacking mechanism 3 and limited block 4 in chuck body have among chuck body
The axially slidable formula guiding mechanism 6 held out against with spring 7.
Using the vee-block 2 of double V-arrangements, also there are small V-arrangement 2b, the large cylindrical of part 5 to be stuck in big V-arrangement 2a on big V-arrangement inclined-plane 2a
On, the die joint of casting is stuck on small V-arrangement 2b, has not only secured the radial degree of freedom of round outer circle, but also secures the axis of the part
To degree of freedom；
Using axially slidable formula guiding mechanism 6, the square conic clamp at special-shaped part back is in guiding mechanism 6, and with zero
The deviation of part shape is slided, and the spring 7 at back ensures guiding mechanism 6 and side's conical contact and compresses, and limits on part circumference
Casting deviation, ensure that the concentricity of macropore and great circle.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, label 5 is the special-shaped part, to become apparent from positioning and the pressure of expression part
Tightly.
The innovation of the utility model is：It is positioned by double V-arrangements and axially slidable formula guiding mechanism can all limit this
The degree of freedom of part ensures that accurate positioning, rapid clamping compress reliable.And it is compressed without multiple spot, avoids machined surface and knife
Tool, it is compact-sized.And it prevents due to dimensioned deviation caused by casting shape disunity.Specifically the fixture changes
Processing technology is changed to lathe process by machining center, greatly improves working efficiency and processing quality, reduces processing cost.
Embodiment described above is only the preferred embodiment of the utility model, and the not feasible implementation of the utility model
It is exhaustive.For persons skilled in the art, it is made under the premise of without departing substantially from the utility model principle and spirit
Any obvious change gone out, should all be contemplated as falling within the claims of the utility model.
