Abstract
The utility model discloses a centering device which comprises a middle base, wherein a centering shaft is connected with a base face at the center of the front part of the middle base and consists of multiple sections of circular shaft which are necked in sequence, the front end of the centering shaft is a pointed end, the front part of a rear base is screwed into the base face of the rear part of the middle bas, a connecting base is connected with the rear part of the rear base and a grip groove is arranged on the side wall of the connecting base. The centering device is simple in structure and easy to realize and can improve the positioning punching effect in a centering process and further improve the production quality of an electric device shell.
Description
Technical field
The utility model relates to the capacitor production field, is specially a kind of Finial device.
Background technology
Capacitor is a kind of device that holds electric charge, and it is widely used in the electron electric power equipment, and circuit is played at a distance from effects such as straight-through friendship, bypass, filtering, resonant tank, power conversion.In the capacitor production process, use top to the capacitor case location drilling.The Finial device of prior art is merely simple circular shaft, and circular shaft one end is shaped to top, and the momentum of top downward punching press is limited during use, and the effect of location drilling is relatively poor.
The utility model content
The utility model purpose provides a kind of Finial device, to solve the relatively poor problem of the top location drilling effect of prior art.
In order to achieve the above object, the technical scheme that the utility model adopted is:
A kind of Finial device includes middle base, it is characterized in that: said middle base rear portion seat surface is provided with screwed hole; The middle base interlude is shaped to step-like, and the anterior seat surface of middle base center is connected with tail spindle, and said tail spindle is made up of the circular shaft of multistage undergauge successively; And the tail spindle front end is most advanced and sophisticated; Also include the back seat of flat-top awl column, the anterior outer wall of said back seat forms external screw thread, and the back seat front portion is screwed in the screwed hole of middle base rear portion seat surface; The back seat rear portion is connected with columned Connection Block through one section cylinder, has on the said Connection Block sidewall and holds groove.
Described a kind of Finial device; It is characterized in that: said tail spindle by the tail spindle back segment of the maximum circular shaft shape of diameter, be connected tail spindle back segment front end face center the tail spindle stage casing, constitute with the tail spindle leading portion that tail spindle stage casing front end is connected through tapered portion, said tail spindle leading portion diameter minimum and tail spindle leading portion front end are shaped to the tip.
Described a kind of Finial device is characterized in that: said back seat rear portion is connected with columned Connection Block through one section cylinder, and said Connection Block diameter is greater than cylinder diameter.
The utility model is simple in structure, is easy to realize.Seat surface forms the screwed hole that supplies back seat to be screwed into after the middle base; Seat surface is connected with tail spindle before the middle base; Tail spindle is the multistage circular shaft formation of undergauge successively, and the momentum that presses down when cooperating middle base can improve the tail spindle punching forms on the Connection Block at back seat rear portion and holds groove; Whole Finial device is connected on the decompressor through Connection Block, and is promptly replaceable if top damage only need be taken off middle base.The utility model can effectively improve top location punching effect, and then has improved the capacitor case quality of production.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1.A kind of Finial device includes middle base 1, and middle base 1 rear portion seat surface is provided with screwed hole; Middle base 1 interlude 2 is shaped to step-like, and middle base 1 anterior seat surface center is connected with tail spindle 3, and tail spindle 3 is made up of the circular shaft of multistage undergauge successively; And the tail spindle front end is most advanced and sophisticated 4; Also include the back seat 5 of flat-top awl column, back seat 5 anterior outer walls form external screw thread, and back seat 5 front portions are screwed in the screwed hole of middle base 1 rear portion seat surface; Back seat 5 rear portions are connected with columned Connection Block 7 through one section cylinder 6, have on Connection Block 7 sidewalls and hold groove 8.
