The realization of this utility model purpose, functional characteristics and advantage will be described further in conjunction with the embodiments referring to the drawings.
Specific embodiment
It should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this
Utility model.
Referring to figs. 1 to Fig. 3, an embodiment of the inner propping collet structure of high precision digital control lathe of the present utility model is proposed,
Be arranged on the main shaft of high precision digital control lathe and can clamping workpiece, main shaft be provided with can with high precision digital control lathe work and front
The plug moving afterwards, inner propping collet structure the end being connected with main shaft be provided be available for plug intert in post holes 300, core
Rod movable with the work of high precision digital control lathe and can in peak at post holes 300 inner top.
Inner propping collet structure includes Gripper body 100, on Gripper body 100 and in step setting interior dagger
200, interior dagger 200 can be embedded on the endoporus of workpiece.Post holes 300 runs through Gripper body 100 and extends to the interior of interior dagger 200
Portion, interior dagger 200 lateral wall is cut device by line and is formed some dops 201 that can uphold outwardly with the movement of plug, core
Rod when mobile the interior inner top peaking at interior dagger 200 dop 201 is uniformly upheld under the compressing dilating effect of plug outwardly simultaneously
And internal stay on the medial wall of workpiece so that workpiece is fixed in inner propping collet structure and guarantees workpiece in stable shape
It is processed under state operating, inner propping collet structure is made up of elastic steel and is set to integrated formed structure.
In the present embodiment, Gripper body 100 lateral wall is provided with an annular stop ring 101 with position-limiting action, can facilitate
Inner propping collet structure is fixed on main shaft.
Gripper body 100 that this utility model inner propping collet structure includes being fixed on main shaft, can clamping workpiece and be in
Dagger 200 in step setting, the diameter of the interior dagger 200 arranging in step is towards the direction away from Gripper body 100 successively
Successively decrease so that interior dagger 200 is embedded at the interior in the hole of workpiece, Gripper body 100, interior dagger 200 and annular stop ring 101 are arranged
The structure that is formed in one simultaneously is made up of elastic steel, and structure is simple, and operation is simple, and production efficiency is high, simultaneously elastic good, using the longevity
Life length.
The post holes 300 of existing inner propping collet structure runs through whole inner propping collet structure, and if interior dagger 200 be divided into
Dry dop 201, interior dagger 200 completely by uniform cut, when plug heads into post holes 300, made by the expansion of plug by dop 201
With and uphold outwardly and in peak on the medial wall of workpiece so that Workpiece clamping is fixed in inner propping collet structure, interior dagger
200 completely by some dops of uniform cutting 201, and such structure is when dop 201 is upheld it is difficult to ensure that the opening of each dop 201
Distance is consistent, and workpiece is susceptible to press from both sides situation askew, that folder is inclined, therefore, is difficult to when workpiece is processed under unsure state
Ensure the endoporus of workpiece and the depth of parallelism of cylindrical concentricity and workpiece both ends of the surface, error is big, and precision is low, produce in machining high-precision
During product, often the scrappage of product is very high, low production efficiency, is unfavorable for the normal operation of high precision digital control lathe processing enterprise.
For solving prior art problem, the post holes 300 of inner propping collet structure of the present utility model runs through Gripper body 100 simultaneously
Extend to inside interior dagger 200, do not run through whole inner propping collet structure, effectively guarantee inner propping collet structure monolithic stability
Property.And dop 201 cuts the lateral wall molding in interior dagger 200 for the device by line, when upholding outwardly interior dagger 200 is not or not dop 201
Become, remain in that the position-limiting action to workpiece so that workpiece is machined out operating at steady-state.When plug moves
To post holes 300 and interior peak at interior dagger 200 inner top when, dop 201 under the compressing dilating effect of plug uniformly outwardly
, so that workpiece is fixed on inner propping collet structure on the medial wall of workpiece, dop 201 is from interior dagger 200 to uphold simultaneously internal stay
Side wall on uphold outwardly, under the positioning action of interior dagger 200, each dop 201 is uniformly upheld outwardly, keep open distance one
Cause, workpiece can stably carry out post-production under the position-limiting action of interior dagger 200 and the internal stay clamping action of dop 201 simultaneously
Operation, effectively prevent workpiece because press from both sides endoporus askew, that folder partially leads to and cylindrical concentricity and workpiece both ends of the surface the depth of parallelism not
Accurately, affect end product quality.Simultaneously after the completion of work pieces process, plug is mobile and removes in post holes 300, and dop 201 loses
The dilating effect of plug, retracted for clearance under the elastic reaction of material itself, workpiece loses internal stay and acts on thus can press from both sides from internal stay
Take out on header structure, be finally completed the processing of workpiece.The inner propping collet structure of high precision digital control lathe of the present utility model is changed
Traditional interior dagger 200 is cut off the structure divided equally, and reaches the standard grade in the side wall of interior dagger 200 and cuts out some dops 201, interior dagger
The extension of 200 pairs of dops 201 has position-limiting action, and the interior dagger 200 being simultaneously embedded on inner hole of workpiece has into one to workpiece
The spacing fixation of step is processed operation to improve precision and the quality of workpiece so that workpiece is maintained at stable state,
Improve production efficiency, reduces the operation cost of enterprise, and structure is simple, reasonable in design, process is simple, low cost of manufacture, and structure is steady
Qualitative good, there is extensive market prospect.
The foregoing is only preferred embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model,
The equivalent structure transformation that every utilization this utility model description and accompanying drawing content are made, or directly or indirectly it is used in other phases
The technical field closed, is all included in the same manner in scope of patent protection of the present utility model.
