On body 100, fixture housing 100 is cylinder, and fixture housing 100 has fixed part, the fixed part of fixture housing 100 is mounted on
On the main shaft of lathe, fixture housing 100 is made to be rotated with the main shaft of lathe, and cylindrical fixture housing 100 rotates more
Steadily, it will not be shaken when workpiece rotates, it is easy to process.The jig main body 200 includes multiple cylindricality collets 101, will during clamping
Workpiece is clamped between multiple cylindricality collets 101.During concrete operations, the cylindricality collet 101 includes connecting portion and folder
Tight portion, connecting portion are used to cylindricality collet 101 being mounted in fixture housing 100, and clamping section is used to clamp workpiece.Clamping workpiece
When, one end of workpiece is inserted into the space that multiple cylindricality collets 101 surround, then bolt 300 is screwed respectively, makes column shape clamp
It is moved in first 101 spaces surrounded towards the multiple cylindricality collet 101, finally clamps workpiece.During using the turning attachment,
Whole operation process is simple and fast, easy to operate, and the clamping effect of workpiece is good, and process safety is reliable.
Fixture housing 100 is installed as the prior art with the main shaft of lathe, and the present embodiment is not improved its structure, because
This, in order to avoid narration repeats burden, without being described in detail.In order to further increase clamping effect, the cylindricality collet 101
Surface be machined with anti-skid chequer, using the cylindricality collet 101 clamp workpiece when, anti-skid chequer can increase cylindricality collet 101 with
Frictional force between workpiece, the clamping effect for making cylindricality collet 101 are more preferable.Anti-skid chequer could be provided as the groove of bar shaped, also may be used
To be set as latticed lines, anti-skidding effect can be realized.Meanwhile anti-skid chequer does not need to be arranged on entire cylindricality collet
101 entire circumferential surface, is arranged on the position for clamping of cylindricality collet 101, and processing is more convenient.
When screwing the clamping workpiece of bolt 300, each cylindricality collet 101 is both provided with multiple bolts 300, multiple bolts
300 power acted on cylindricality collet 101 can be uniformly distributed on entire cylindricality collet 101, and clamping effect is good；Further
, setting is in the spring of tensional state between the nut of the bolt 300 and fixture housing 100, effectively prevent 300 pine of bolt
Dynamic, the clamping effect of bolt 300 is more preferable.
In the preferred embodiment of the embodiment, the cylindricality collet 101 is set as three, according to different workpiece to be processed
Situation do not select different number cylindricality collet 101 fixture, convenient for by Workpiece clamping.The obvious cylindricality collet 101 can
To be set as four.
In the preferred embodiment of the embodiment, multiple bar shaped mounting grooves 102, institute are correspondingly arranged in the fixture housing 100
It states multiple bar shaped mounting grooves 102 along the axis direction of the fixture housing 100 to extend, and the notch difference of a plurality of mounting groove
Towards the inside of the fixture housing 100, multiple connecting portions, which correspond, to be located in a plurality of mounting groove；The screw thread
Hole extends to the slot bottom of the bar shaped mounting groove 102.Bar shaped mounting groove 102 is convenient for determining the installation site of cylindricality collet 101, column
The installation site of clevis head 101 is more accurate, and clamping effect is good；The length of bar shaped mounting groove 102 can be with cylindricality collet 101
Length is identical, saves rapidoprint；Further, the clamping section is cylindrical, and the connecting portion and the clamping section
Diameter is identical, i.e. the processing convenient for column shape clamp head 101, also allows for the processing of bar shaped mounting groove 102, shortens manufacturing time, section
Cost is saved.Preferably, the multiple bar shaped mounting groove 102 is uniformly distributed along the circumferential direction of the fixture housing 100, during clamping,
Workpiece is more uniformly stressed, and the clamping effect of workpiece is more preferable.
Bar shaped mounting groove 102 is arranged in a one-to-one correspondence with cylindricality collet 101, easy to process, saves material.Such as：Column shape clamp
First 101 are processed as three, and corresponding bar shaped mounting groove 102 is processed as three.
In the preferred embodiment of the above embodiment, the slot bottom of the bar shaped mounting groove 102 is semicircular arc, the semi arch
The radius of shape is identical with the radius of the connecting portion, and when clamping workpiece, cylindricality collet 101 moves cylindricality collet 101 towards workpiece
Dynamic, the cell wall of bar shaped mounting groove 102 has the function of guiding, and during Workpiece clamping, clamped position is more accurate, easy to process.
In the preferred embodiment of the embodiment, the turning attachment further includes intermediate plate, and the intermediate plate is located at bar shaped installation
In slot 102；
The bolt 300 includes the first bar portion 201 and is set in the sleeve 202 of first bar portion 201, and described first
Bar portion 201 is spirally connected with the sleeve 202, and the sleeve 202, the sleeve are stretched out in the both ends of first bar portion 201 respectively
202 are connect with the screw hole, the fixture housing 100 with the connecting portion by first bar portion 201；The folder
Piece is mounted in first bar portion 201, and the intermediate plate is between the sleeve 202 and the connecting portion, the sleeve
202 relative to first bar portion 201 when moving, and enables the intermediate plate along the axial direction of first bar portion 201 relative to institute
The first bar portion 201 is stated to move.This is simple and reasonable, in the clamping for carrying out workpiece, first screws the first bar portion 201, makes the
One bar portion 201 is pushed against on cylindricality collet 101；Then, then sleeve 202 is screwed, the first contact jaw of sleeve 202 makes intermediate plate direction
Cylindricality collet 101 moves, and intermediate plate is pushed against on cylindricality collet 101.The area of intermediate plate is big, i.e., sleeve 202 is acted on column shape clamp
The power of any is dispersed on entire intermediate plate on first 101, and intermediate plate is made to be pushed against on cylindricality collet 101, and the stress of cylindricality collet 101 is more
Add uniformly.During practical operation, the power of multiple sleeves 202 is acted on the same intermediate plate, i.e., each cylindricality collet
101 are correspondingly arranged there are one intermediate plate, and the sleeve 202 for screwing multiple bolts 300 of same cylindricality collet 101 is pushed against together
On one intermediate plate, intermediate plate is more preferable to the clamping effect of cylindricality collet 101.
For the ease of screwing for bolt 300, in the preferred embodiment of the embodiment, the bolt 300 further includes hexagonal (hexagon)nut
203, the hexagonal (hexagon)nut 203 is located at one end far from the intermediate plate of first bar portion 201, and the hexagonal (hexagon)nut 203
It is fixedly connected with first bar portion 201.Hexagonal (hexagon)nut 203 is easy to process, and use scope is wide, at low cost.During actual processing, spiral shell
Cap is structure as a whole with the first bar portion 201, and one end of the first bar portion 201 is directly processed as to the structure of hexagonal (hexagon)nut 203.
In the preferred embodiment of the embodiment, the bolt 300 further includes operating lever 204, and the operating lever 204 is located at described
One end far from the intermediate plate of sleeve 202, and the operating lever 204 is fixed on the sleeve 202, the operating lever 204
The centerline dip of center line and the sleeve 202 is set.Convenient for turnbarrel 202, make sleeve 202 that intermediate plate is pushed against cylindricality
On collet 101.In the preferred embodiment of the embodiment, the center line phase of the center line of the operating lever 204 and the sleeve 202
Vertically, convenient for rotation, when rotation, is more laborsaving.
The structure of operating lever 204 is simple, is made of steel, and intensity is high, safe to use；Hollow stem can be processed as, is saved
Material saving；Further, protective layer can be arranged in operating lever 204, protective layer is made of elastic material, is held and is more relaxed
Suitable, use is safer.
