Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
Shockproof fixture suitable for thin-wall part as shown in Figure 1, Figure 2 includes to hold down assembly 1, and unusual place is:
Hold down assembly 1 lower section be provided with limit contact surface 2, limit contact surface 2 on Buffer Unit 3 is installed, hold down assembly 1 lower section
It is also connected with main ringfeder component, 1 top of holding down assembly is provided with secondary ringfeder component.In this way, in order to realize to parts to be processed
11 all position locked, realization is effective shockproof, during being in locking state, main ringfeder component and secondary ringfeder attached components touching.
From the point of view of the preferable embodiment of the utility model one, what is used holds down assembly 1 as compression nylon ring.It is specific next
It says, compressing nylon ring includes circle ontology.In order to realize the strong fix to parts to be processed 11, setting in the circle ontology of use
There is support extension side.It compresses nylon ring as a result, to cooperate by the shape of contoured design and parts to be processed 11, inside leads to again
It crosses structure to be thinned, with good elasticity, nylon ring deforms first in this way after pressure touches product is adapted to outside product
Shape not will cause deformation of products and beat overproof.
Meanwhile in order to preferably be bonded the shape of parts to be processed 11, supports and set between extension side and the inner wall for enclosing ontology
It is equipped with positioning step.Specifically, limit contact surface 2 is provided with below the circle ontology of use, the edge of limit contact surface 2 is opened
Equipped with holding tank.In this way, Buffer Unit 3 can be allowed to be embedded in holding tank during practical set.Dislocation is avoided the occurrence of as a result,
Preferably realize buffering.From the point of view of actual implementation, rubber ring is constituted using Buffer Unit 3.The effect of rubber ring as a result, is
Further soft and smooth clamping force, decay cutting vibration by the elasticity of rubber ring.Also, in order to meet the to be processed of different bores
The shockproof positioning of part 11 needs, and the diameter of section of rubber ring is 2 to 5 millimeters.
Furthermore, in order to effectively rely on deformation realize expansion positioning, the utility model use main ringfeder component
Include mandrel ontology for ringfeder mandrel 4, expansion-head 5 is provided at the top of mandrel ontology, is distributed in expansion-head 5 several swollen
Swollen slot 6.Simultaneously, it is contemplated that when ringfeder mandrel 4 combines, preferable deformation effects can be possessed effectively in conjunction with secondary ringfeder component,
The expansion slot 6 used equidistantly distributes between each other for vertical direction.It is to apply close in whole circumference to product internal diameter as a result,
Pressure, the excessive deformation problem for avoiding traditional three-jaw from clamping.
Meanwhile compress nylon ring in order to allow and preferably combined with parts to be processed 11, avoid the occurrence of in conjunction with gap and
In conjunction with offset, the secondary ringfeder component that the utility model uses includes ringfeder screw 7, and the lower section of ringfeder screw 7 is connected with compression
Gasket 8.Specifically, the ringfeder screw 7 of use includes screw ontology, and the upper end of screw ontology is provided with limit film 9, limit
Piece 9 is contacted with compress gasket 8, and taper configurations 10 are distributed in the lower end of screw ontology.In this way, in main ringfeder component and secondary ringfeder group
When part be combined with each other, taper configurations 10 are embedded in expansion-head 5, realize and preferably combine.During actual use, user is rotated with spanner
When ringfeder screw 7, the conical surface of ringfeder screw 7 pushes to be opened outside the spring cylinder part of ringfeder mandrel 4, to clamp workpiece diameter.
During this period, 8 sets of compress gasket on ringfeder screw 7, in 7 tensioner expanding arbor of ringfeder screw, compress gasket 8 is acted on centainly
Power to compressing on nylon ring, make to compress nylon ring and rubber ring fitting processed product but be unlikely to make processed product by
Deformation is generated in stress.During implementing, the thickness needs of compress gasket 8 are thickened and are thinned according to actual use situation.
So that it is principle that it is again indeformable, which to be pressed onto product, for rubber ring, shockproof effect when in conjunction with cutting is thickened or is thinned.
The working principle of the utility model is as follows:
A secondary soft pawl of lathe is installed on scroll chuck first, is gone out according to the size vehicle of expanding arbor tail portion clamping part
Corresponding size.Then, expansion assembly is installed in the good three-jaw of vehicle and is clamped.Parts to be processed is installed to ringfeder mandrel
On, direction cannot be put back.Rubber ring and compression nylon ring needs are fitted together and are fixed in advance.The assembly set fixed
On the outer diameter of product shaft end.Compress gasket is set on ringfeder screw and ringfeder screw is screwed into expanding arbor, uses torque wrench
It is screwed into the power size of setting, clamping is to complete.Because the clamping time is longer, identical jig can be made two width, a slave
Outer clamping is processed on one slave bed, can save the waiting of lathe caused by due to clamping in this way.
It can be seen from the above written description and the attached drawings that gathering around and having the following advantages after using the utility model:
1, it is designed using the mandrel of expansion type, realizes that clamping benchmark and measuring basis are unified, meet the higher jump of product
It is dynamic to require.
2, it is designed using Flexible Fixturing, effectively inhibits the vibration in product processing.
3, the exchange with conventional limit assembly may be implemented, the clamping time is transferred to outside machine in realization machine, improves lathe benefit
With rate.
4, by using the full cladding installation way of micro-deformation, clamping reliability and clamping efficiency are improved.
The above is only the preferred embodiment of the utility model, is not intended to limit the utility model, it is noted that
For those skilled in the art, without deviating from the technical principle of the utility model, it can also do
Several improvements and modifications out, these improvements and modifications also should be regarded as the protection scope of the utility model.
