The invention discloses a kind of Thin-wall Revolving Part inner hole support devices, it include: adjusting nut (2), spring spiro rod (3), link block (4) and adjusting block (5), there are six wherein spring spiro rod (3) is total to, there are five link block (4) is total, six spring spiro rods (3) replace with five link blocks (4) to be sequentially connected with, head end spring spiro rod (3) is fixedly connected with the threaded hole of adjusting block (5), and spring spiro rod (3) end in end is mounted in the unthreaded hole of adjusting block (5) by adjusting nut (2).Apparatus of the present invention improve the versatility of tooling by using adjustable inner hole support device, and the processable region when process supported using inner hole has also been enlarged.
Description
Technical field
The present invention relates to a kind of revolving parts inner hole support device, especially a kind of Thin-wall Revolving Part inner hole support
Device.
Background technique
Thin-wall Revolving Part is the revolving parts that the ratio between a kind of diameter and wall thickness are not less than 20, is carrying out outer circle and end
It is needed when the turnery processing in face using inner hole as positioning and clamping benchmark, props up thin-walled revolution usually using toolings such as internal expansion type mandrels
The inner hole of body part, this installation way increase contact area when parts fixation, control clamping flexible deformation, and can obtain
Enough clamping forces are taken, therefore are widely applied in turnery processing.
However, the toolings such as internal expansion type mandrel used when the turnery processing of Thin-wall Revolving Part outer circle and end face are using
When have the following problems: first is that the size of every kind of internal expansion type mandrel tool is with the hole size of Thin-wall Revolving Part be cooperation
Size, the different process segments is inconsistent due to inner bore of part size, and needing to customize new internal expansion type mandrel tool can be real
Existing size matches clamping, and the versatility of tooling is poor；Second is that in order to obtain enough clamping powers, by thin-walled revolution workpiece zero when use
Part is covered in the outside of internal expansion type mandrel, and mandrel stretches out the both ends of part, cannot achieve Thin-wall Revolving Part interior step inner hole
Processing, tooling shape limits the processable region of part.Therefore Thin-wall Revolving Part inner hole clamping recruitment how is improved
Filling the limitation that region can be processed to part to the versatility and tooling shape of different-diameter inner hole is problem in the urgent need to address.
Summary of the invention
It is an object of that present invention to provide a kind of Thin-wall Revolving Part inner hole support devices, solve prior art poor universality
And the problem of region can be processed in tooling shape limit feature.
A kind of Thin-wall Revolving Part inner hole support device, comprising: adjusting nut, spring spiro rod, link block and adjusting block.
It is spring in the middle part of each spring spiro rod, both ends are screw rod there are six the spring spiro rod is total；The link block is arc
Shape, both ends have the threaded hole that matches with spring spiro rod, link block altogether there are five；The adjusting block is arc, and one end has
The threaded hole to match with spring spiro rod, the other end have the unthreaded hole of diameter 0.3mm bigger than the spring spiro rod diameter of thread.
Six spring spiro rods replace with five link blocks to be sequentially connected with, adjacent springs screw rod and link block spiral shell fixed
Fixed, head end and end are spring spiro rod；Head end spring spiro rod is fixedly connected with the threaded hole of adjusting block, end spring spiro rod end
Portion is mounted in the unthreaded hole of adjusting block by adjusting nut.
Thin-wall Revolving Part inner hole support device will connect in use, Thin-wall Revolving Part end face is horizontally arranged
Good ring supporting device is assemblied in the inner hole of Thin-wall Revolving Part, adjusts adjusting nut, makes link block and adjusting block
Positive camber forms Thin-wall Revolving Part inner hole and squeezes, and link block and adjusting block is made to be fixed on the inner hole of Thin-wall Revolving Part
On surface, to carry out the processing of the outer circle of Thin-wall Revolving Part, end face and inner bore of step, unclamps adjust after processing is completed
Nut takes out and dismantles support device.
Apparatus of the present invention improve the versatility of tooling, having also been enlarged makes by using adjustable inner hole support device
Processable region when the process supported with inner hole.
