Abstract
The utility model relates to a kind of rear pull type and to rise folder chucking appliance system, comprise ring flange, housing, connection sliding block, centrepin, rise sandwich and locating piece, ring flange, housing and locating piece are coaxially installed successively, a connection sliding block is coaxially set in housing, the front end of this connection sliding block coaxially connects the sandwich that rises, and the front end of this sandwich that rises extends to the front end outer side of locating piece; Coaxially arrange a centrepin in sandwich inside of rising, the rear end of this centrepin is arranged on housing, and the front end of this centrepin is the conical surface with the contact surface of the sandwich that rises.The utility model is adapted at clamping internal diameter and requires that strict part adds to axiality, the depth of parallelism etc. using man-hour, this rear pull type rises and presss from both sides the action that chucking appliance system has post-tensioning while clamping with workpiece diameter, can produce plurality of advantages such as reducing deflection, raising machining accuracy, increase work efficiency after therefore using.
Description
Technical field
The utility model relates to the clamping tool in machined production technical field, and especially a kind of rear pull type rises folder chucking appliance system.
Background technology
At present, use lathe to add man-hour to workpiece, usually adopt scroll chuck to position.The chucking power that tradition scroll chuck only has outwards (inwards) to move, there is no back pull.Easily being out of shape when clamping internal diameter, there is axiality difference, the bad shortcoming occurred frequently of the depth of parallelism, bringing many drawbacks to the production of enterprise.
Summary of the invention
The purpose of this utility model is to make up the deficiencies in the prior art part, provide a kind of be applicable to clamping internal diameter and the rear pull type of good clamping effect rises folder chucking appliance system.
The purpose of this utility model is realized by following technological means:
A kind of rear pull type rises folder chucking appliance system, it is characterized in that: comprise ring flange, housing, connection sliding block, centrepin, rise sandwich and locating piece, ring flange, housing and locating piece are coaxially installed successively, a connection sliding block is coaxially set in housing, the front end of this connection sliding block coaxially connects the sandwich that rises, and the front end of this sandwich that rises extends to the front end outer side of locating piece; Coaxially arrange a centrepin in sandwich inside of rising, the rear end of this centrepin is arranged on housing, and the front end of this centrepin is the conical surface with the contact surface of the sandwich that rises.
And the diameter of the conical surface front end face of described rise sandwich and centrepin is less than the diameter of rear end face.
And described connection sliding block is connected with the sandwich that rises by connecting pin.
Advantage of the present utility model and good effect are:
1, rise sandwich and the centrepin of this cover system are cone match, the sandwich conical surface that rises coordinates with centrepin when moving backward and slides, the sandwich clamping face that makes to rise evenly opens, owing to there being the action of post-tensioning while clamping with workpiece diameter, therefore axiality can ensure within 0.03mm, the depth of parallelism can ensure at 0.008mm, and ID distortion amount is no more than 0.002mm.
2, the stability owing to using this cover system can improve clamping, workpiece is not yielding, has therefore ensured product quality, reduces percent defective, has saved production cost.
3, this cover system has quick-replaceable fixture, the advantage of remodeling fast, and its fastest conversion time is within 10 minutes, and change simple and convenient, easily grasp.
4, the utility model is adapted at clamping internal diameter and requires that strict part adds to axiality, the depth of parallelism etc. using man-hour, this rear pull type rises and presss from both sides the action that chucking appliance system has post-tensioning while clamping with workpiece diameter, can produce plurality of advantages such as reducing deflection, raising machining accuracy, increase work efficiency after therefore using.
Accompanying drawing explanation
Fig. 1 of the present utility modelly partly cuts open figure.
Detailed description of the invention
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing; It should be noted that, the present embodiment is narrative, is not determinate, can not limit protection domain of the present utility model with this.
A kind of rear pull type rises folder chucking appliance system, comprise ring flange 1, housing 2, connection sliding block 3, centrepin 6, rise sandwich 5 and locating piece 7, ring flange, housing and locating piece are coaxially installed successively, a connection sliding block is coaxially set in housing, the rear end of this connection sliding block is connected with spindle of numerical control lathe pull bar, the front end of this connection sliding block coaxially connects the sandwich that rises by connecting pin 4, and the front end of this sandwich that rises extends to the front end outer side of locating piece; Coaxially arrange a centrepin in sandwich inside of rising, the rear end of this centrepin is arranged on housing, and the front end of this centrepin is the conical surface with the contact surface of the sandwich that rises, and the diameter of this conical surface front end face is less than the diameter of rear end face.
Operation principle of the present utility model is:
1, by trade union college in the front end of rising by sandwich;
2, spindle of numerical control lathe pull bar is by power transmission to connection sliding block, and connection sliding block drives connecting pin motion;
3, connecting pin drives the sandwich that rises to move backward;
4, the sandwich conical surface that rises coordinates with centrepin when moving backward and slides, and the sandwich clamping face that makes to rise evenly opens;
5, the sandwich that rises open in process continue backward tension, until workpiece and locating piece are adjacent to.
