Abstract
The utility model relates to an elastic collet used for installing a point-electrode, which comprises a collet main-body. An elastic clamping core provided with a bayonet is arranged at one end of the collet main-body, and the end of the collet main-body is further sleeved with a locknut which is matched with the elastic clamping core. In the elastic collet, because the point-electrode which is clamped is positioned in an opening at the center of the elastic clamping core through mutual matching between the elastic clamping core and the locknut and then the locknut of the collet is screwed clockwise, the clamping of the point-electrode which is clamped (or parts with minor diameter) is completed, and the whole clamping process is completed; the structure is simple, the machining and the installation are convenient, the operation is stable and reliable, and the adaptability is strong.
Description
Technical field
The utility model relates to a kind of collet, is specifically related to a kind of point electrode that is used for electron gun metal parts when welding and installs and use collet
Background technology
In electron gun metal parts welding, on the weld jig during mounting points electrode because the diameter little (￠ 1mm) of point electrode, the fixing difficulty of clamping has brought suitable inconvenience for the mounting points electrode.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, and clamping and convenient disassembly are rapid, and be reliable and stable, and long-lived point electrode is installed and used collet.
For achieving the above object, the technical solution adopted in the utility model is: comprise clamper main body, be characterized in, be provided with the elasticity the core of the card that has bayonet socket at an end of clamper main body, and also also be set with the locking nut that matches with the elasticity the core of the card on the clamper main body at this end.
Elasticity the core of the card of the present utility model is a pyramidal structure.
Because the utility model is put into the point electrode that is held by cooperatively interacting of elasticity the core of the card and locking nut the opening at elasticity the core of the card center, clockwise direction screws the chuck locking nut then, the point electrode (or minor diameter part) that is held can be clamped, finish whole clamping process, it is simple in structure, processing, easy for installation, stable operation is reliable, and applicability is strong.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are described in further detail.
Referring to Fig. 1, the utility model comprises clamper main body 1, is provided with the elasticity the core of the card 2 of the pyramidal structure that has bayonet socket at an end of clamper main body 1, and also also is set with the locking nut 3 that matches with elasticity the core of the card 2 on the clamper main body 1 at this end.
Only need counter-clockwise direction to unscrew chuck locking nut 3 during use, again the point electrode (or minor diameter part) that is held is put into the opening at chuck elasticity the core of the card 2 centers, clockwise direction screws chuck locking nut 3 then, the point electrode (or minor diameter part) that is held can be clamped, finish whole clamping process.The utility model by chuck locking nut 3 inner conical surface and the male cone (strobilus masculinus) of chuck elasticity the core of the card 2 between the radial component (axial thrust load of the frictional force of generation makes chuck locking nut 3 axially making straight ahead or retreating mobile along clamper main body 1) of the frictional force that produces the dop portion of chuck elasticity the core of the card 2 clamped and unclamp the point electrode (or minor diameter part) that is held, finish whole clamping process.
Claims (2)
1, a kind of point electrode is installed and is used collet, comprise clamper main body (1), it is characterized in that: the end at clamper main body (1) is provided with the elasticity the core of the card (2) that has bayonet socket, and also also is set with the locking nut (3) that matches with elasticity the core of the card (2) on the clamper main body (1) at this end.
