Description
Technical field
The utility model relates to auto parts and components manufacture fields, more particularly, to a kind of for swollen folder in sprocket wheel processing
Head.
Background technique
There are commonly hydraulic three-jaw chuck and cylinder grippers for numerically controlled lathe clamping workpiece.Three-jaw chuck uses three-point fix, leads to
It is high with property, but be not suitable for clamping the Flexible Deforming Parts such as thin-wall pipe；Cylinder gripper is positioned with workpiece outer diameter and is clamped inside it,
It need to be particularly customized by workpiece outer diameter.For through-hole parts, chip when turning remains on the positioning surface inside cylinder gripper, is not easy
Cleaning, position inaccurate when causing subsequent clamping, influences machining accuracy.In addition, the pipe fitting using Internal hole positioning more in recent years
Swollen collet, chip are easy to clean in turning.
Currently, the interior swollen collet for being conventionally used to sprocket wheel processing exists, structure is complicated, and Various Types of Dams, clamping is illusive to ask
Topic.
Summary of the invention
In a kind of the technical problem to be solved by the utility model is to provide structures simple, easily operated and clamping is firm
Swollen collet.
Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of for swollen folder in sprocket wheel processing
Head, including ring flange, sleeve and locating shaft, the ring flange are equipped with axis hole, and the sleeve includes inner hole and exit orifice, described
The outer bore dia of sleeve be greater than its diameter of bore, the exit orifice is located at sleeve tail portion and is bellmouth, if the sleeve by
Dry positioning piecemeal is spliced, and several positioning piecemeals are arranged along flange shaft bore edges and at predetermined intervals, if described
Dry positioning piecemeal can be radially movable along axis hole, and the inner sidewall of the positioning piecemeal tail portion is inclined-plane, the locating shaft
Including head and tail portion, the locating shaft tail portion is adapted in dove-tail form and with the exit orifice of sleeve, the locating shaft tail portion
Diameter is greater than its head diameter, and the inner hole is equipped with retention bead, and the locating shaft is equipped with and limit at caudad
The adaptable limiting slot of protrusion, the positioning shaft head can be from the axis hole that sleeve exit orifice is inserted into ring flange.
It is further improved as the utility model, the locating shaft can be spirally connected with the axis hole of ring flange.
It is further improved as the utility model, the quantity of the positioning piecemeal is 4.
Compared with prior art, that the utility model has the advantage of structures is simple, easily operated, clamping is firm, it is simple come
It says, by sprocket wheel housing on sleeve, the spindle nose of locating shaft is inserted into its inner hole from sleeve exit orifice, then be inserted into flange from inner hole
It in the axis hole of disk, is finally pierced by from the axis hole of ring flange, the tail portion of locating shaft and the exit orifice of sleeve cooperate, on hub internal bore
Retention bead is stuck in the limiting slot of locating shaft, and several positioning piecemeals are radially moved along axis hole, by housing on sleeve
Sprocket wheel blocks, at this point, the lateral wall of positioning piecemeal is tightly bonded with the inner sidewall of sprocket wheel, realizes the clamping of sprocket wheel.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model one；
Fig. 2 is the utility model structure diagram two；
Fig. 3 is the utility model structure diagram three.
Specific embodiment

Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only to explain this
Utility model is not used to limit the utility model.
It is as shown in Figure 1 to Figure 3: a kind of for swollen collet in sprocket wheel processing, including ring flange 1, sleeve and locating shaft 2,
Ring flange 1 is equipped with axis hole 3, and sleeve includes inner hole 4 and exit orifice 5, and 5 diameter of sleeve exit orifice is greater than its 4 diameter of inner hole, and exit orifice 5 is located at
Sleeve tail portion and be bellmouth, sleeve is spliced by several positioning piecemeals 6, several positioning piecemeals 6 along 3 edge of flange axis hole and
It arranges at predetermined intervals, several positioning piecemeals 6 can be radially movable along axis hole 3, and the inner sidewall of positioning 6 tail portion of piecemeal is oblique
Face, locating shaft 2 include head and tail portion, and 2 tail portion of locating shaft is adapted in dove-tail form and with the exit orifice of sleeve 5,2 tail portion of locating shaft
Diameter is greater than its head diameter, and inner hole 4 is equipped with retention bead 7, and locating shaft 2 is equipped with suitable with 7 phase of retention bead at caudad
The limiting slot 8 answered, 2 head of locating shaft can be from the axis holes 3 that sleeve exit orifice 5 is inserted into ring flange 1.
Locating shaft 2 can be spirally connected with the axis hole 3 of ring flange 1.
The quantity for positioning piecemeal 6 is 4.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
