Abstract
The utility model discloses a clamping device for growing section of thick bamboo thin wall part, its characterized in that: including chuck (1), elastic sleeve (2) and centre frame (3), elastic sleeve (2) hole is the step hole, carries out axial positioning to the work piece, and elastic sleeve (2) excircle has a plurality of elongated slots along the even processing of axial, and the jack catch of elastic sleeve (2) and chuck (1) cooperates to be connected, in work piece one end stretched into the elastic sleeve, the other end was connected with the centre frame. The utility model discloses a design transition elastic sleeve presss from both sides tightly the work piece, can effectively prevent because of the influence of the poor deformation that produces of the rigidity of work piece to part machining precision, improves the force distribution of work piece exposed core, reduces to warp to guarantee the machining precision. The utility model discloses simple structure, convenient operation, economical and practical.
Description
Technical field
This utility model belongs to machining technology field, is related to a kind of clamping device for long cylinder thin-walled parts.
Background technology
When processing long cylinder thin-walled parts endoporus on boring boring machine, by the way of " folder one support " (chuck and centre frame),
Realize the clamping to long cylinder thin wall and deep hole part.There is problems with this installation way, because chuck-end claw is direct and workpiece
Surface contacts, easy damaged surface of the work, because workpiece wall is relatively thin, is also easy to produce pinching deformation, and then has influence on the processing essence of part
Degree.
Utility model content
The purpose of this utility model is the defect in order to overcome prior art, solves the deformation producing because of the poor rigidity of workpiece
Impact to part processing precision, proposes a kind of clamping device for long cylinder thin wall and deep hole part.
The technical solution of the utility model is：A kind of clamping device for long cylinder thin-walled parts it is characterised in that：Including
Chuck 1, resilient sleeve 2 and centre frame 3；Resilient sleeve 2 endoporus be stepped hole, workpiece is carried out with axially position, resilient sleeve 2 cylindrical along axle
To being uniformly machined with multiple elongated slots, resilient sleeve 2 is connected with the claw of chuck 1；Workpiece one end is stretched in resilient sleeve, the other end
It is connected with centre frame.
Beneficial effect：When this utility model processes long cylinder thin wall and deep hole part on deep hole drilling and boring machine, using " a folder one
Support " installation way, by design transition resilient sleeve, workpiece is clamped, can effectively prevent because workpiece poor rigidity produce
The impact to part processing precision for the deformation, improves the distribution of force at piece-holder end, Reducing distortion, to ensure machining accuracy.This
Utility model structure is simple, easy to operate, economical and practical.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
For making the purpose of this utility model, content and advantage clearer, specific embodiment of the present utility model is made
Describe in further detail.
This utility model provides a kind of clamping device for long cylinder thin-walled parts to include：Chuck 1, resilient sleeve 2, centre frame
3；Chuck 1 and centre frame 3 are to bore boring machine to have adnexa by oneself, and resilient sleeve 2 endoporus is stepped hole, and step is used for the axially position of workpiece,
Cylindrical 6 elongated slots of processing vertically, 6 elongated slots are uniform in circumferencial direction.During clamping workpiece 4, resilient sleeve 2 is loaded in claw,
Again one end of workpiece is stretched in resilient sleeve, the other end of workpiece is held up with centre frame, then clamps workpiece centering.This practicality
In new, workpiece configurations are stepped, and endoporus forms through multiple boring and cylindrical, endoporus acted as reference mutual, alternately processes, for reducing
Endoporus mismachining tolerance, during bore hole, need to reverse end for end feed and replace feed from the two ends of workpiece respectively, therefore, resilient sleeve should become
Group makes.
The above is only preferred implementation of the present utility model it is noted that common skill for the art
For art personnel, on the premise of without departing from this utility model know-why, some improvement can also be made and deform, these change
Enter and deform also to should be regarded as protection domain of the present utility model.
