Abstract
A transmitter shell body includes a pedestal and a cylinder body, wherein a boss is arranged on the pedestal, and a groove matched with the boss is arranged at a port in the inner side of the cylinder body; and the outer surface of the front end of the pedestal is provided with a plurality of positioning devices, and the inner side of the cylinder body is provided with a limiting groove matched with the positioning devices. By respectively arranging the groove and the boss on the pedestal and the cylinder body, and arranging the positioning balls on the pedestal, the transmitter shell body solves the problems that the requirement for coaxiality cannot be ensured and the welding quality is not good after the existing transmitter shell body adopts the threaded connection; and the corners on the outer sides of the bottom part of the groove are configured to be round chamfers, thereby facilitating the clamping-in of the positioning balls.
Description
Technical field
the utility model relates to mechanical design field, specifically a kind of shell of transducer.
Background technology
At present, shell of transducer is the general thread connecting mode that adopts in the time of welding, pedestal front end is provided with external thread, and cylindrical shell inner side is provided with internal thread, after pedestal and cylindrical shell are threaded connection, carry out again laser bonding, because fitness between screw thread is not high, pedestal and cylindrical shell can not ensure right alignment requirement, and after being threaded, gap is larger, when laser bonding, easily produce bubble, affect the welding quality of shell of transducer.
Utility model content
The shortcoming existing in order to overcome above-mentioned prior art, the purpose of this utility model is to provide a kind of shell of transducer, and it has ensured pedestal and the requirement of cylindrical shell right alignment, and after connecting, welding quality is higher.
In order to address the above problem, the utility model by the following technical solutions: a kind of shell of transducer, comprise pedestal and cylindrical shell, it is characterized in that, on described pedestal, be provided with boss, be provided with in the port of cylindrical shell inner side the groove coordinating with described boss; Be provided with some locating devices at the outside surface of described pedestal front end, be provided with in described cylindrical shell inner side the stopper slot coordinating with described locating device.
Further, described locating device comprises location hoodle, described pedestal is provided with the hole of matching with the base of locating hoodle, and the base of described location hoodle is arranged in described hole, is provided with in described cylindrical shell inner side the semi-round ball connected in star coordinating with described location hoodle.
Further, the exterior angle of described groove is rounded corner.
The beneficial effects of the utility model are: it by arranging respectively groove and boss on pedestal and cylindrical shell, and on pedestal, be provided with location hoodle, solve after present shell of transducer employing is threaded and can not ensure that right alignment requires and the not high problem of welding quality; Angle by bottom portion of groove outside is set to rounded corner, conveniently snapping in of location hoodle.
Brief description of the drawings
below in conjunction with drawings and Examples, the utility model is described further:
Fig. 1 is the structural representation before the utility model connects;
Fig. 2 is the enlarged drawing of A in Fig. 1;
Fig. 3 is the structural representation after the utility model connects.
Embodiment
As shown in Figure 1, an embodiment of the present utility model comprises pedestal 1 and cylindrical shell 2, on described pedestal 1, is provided with boss 3, is provided with in the port inner side of cylindrical shell 2 groove 4 coordinating with described boss 3; Be provided with some location hoodle 5 at the outside surface of described pedestal 1 front end, described pedestal is provided with the hole of matching with the base of locating hoodle 5, the base of described location hoodle 5 is fixedly installed in described hole, is provided with in described cylindrical shell 2 inner sides the semi-round ball connected in star 6 coordinating with described location hoodle 5.Further, as shown in Figure 2, larger in order to prevent from locating the resistance that hoodle 5 is subject in the time entering cylindrical shell 2, the exterior angle of groove 4 bottoms is set to rounded corner 7, and when rounded corner 7 contacts with location hoodle 5, location hoodle is gone down by rounded corner 7 extruding easily; Certainly, except the disclosed location of this embodiment hoodle, the utility model also can adopt other locating devices, for example, spring positioning etc., the object that this place arranges locating device is in order to ensure that transmitter cylindrical shell and pedestal keep relative stability in the time welding, can not to relatively move, also having afterwards certain firm effect in welding.
As shown in Figure 3, after the utility model installation, location hoodle 5 snaps onto in the semi-round ball connected in star 6 of cylindrical shell 2 inner sides, has ensured stablizing between pedestal 1 and cylindrical shell 2, boss 3 and groove 4 closely cooperate, and adopt laser bonding in the junction of pedestal 1 and cylindrical shell 2 outside surfaces.
Claims (3)
