Description

Be suitable for automatic assembly location's cover shell

Technical Field

The utility model relates to a be suitable for cover shell of automatic assembly location.

Background

Generally speaking, the materials for the buzzer casing generally select thermoplastic polyester PBT, PPO, or thermoplastic PPS, PC, when the casing is assembled on the automatic production line, for keeping the operation continuity, the assembly standard is unified, in order to improve the operating efficiency, the casing is required to be put consistently in position on the assembly line, for this reason, the casing needs to be accurately positioned, and common casing is when getting into the assembly line, generally arrange neatly in unison in a manual mode, so that the improvement of production efficiency is influenced, and the accuracy is also relatively poor.

Disclosure of Invention

The to-be-solved technical problem of the utility model is: in order to overcome the deficiency among the prior art, the utility model provides a be suitable for automatic assembly location's cover shell to alleviate operation intensity, improve the assembly accuracy.

The utility model provides a technical scheme that its technical problem adopted is: the casing suitable for automatic assembling and positioning comprises a tubular casing, wherein a sounding resonant cavity is arranged at the lower part of the casing, a sounding pipe positioned in the sounding resonant cavity is arranged at the center of the inner bottom surface of the casing, a sounding hole of the sounding pipe is communicated with the sounding resonant cavity and the outside, and positioning ribs are arranged on the inner wall of the casing where the sounding resonant cavity is positioned.

Furthermore, six rectangular support columns protruding inwards are uniformly distributed on the inner wall of the shell where the sounding resonant cavity is located in the circumferential direction, and the positioning ribs are located between the two rectangular support columns.

The edge of the upper end face of the shell is provided with an arc-shaped bulge, and the arc-shaped bulge is matched with a clamping groove matched with the upper cover of the buzzer, so that the upper cover can be conveniently assembled and connected.

The utility model has the advantages that: the utility model discloses a set up the location muscle on shells inner wall, can fix a position the muscle and arrange the buzzer shell on the automatic line as the benchmark when the assembly to reach that the position is unified, assemble accurate purpose, alleviate operation intensity and improve the operating efficiency simultaneously.

Drawings

The present invention will be further described with reference to the accompanying drawings and embodiments.

Fig. 1 is a schematic diagram of the three-dimensional structure of the present invention.

Fig. 2 is a schematic sectional structure diagram of the present invention.

In the figure: 1. the sound-producing device comprises a shell, 2 sound-producing resonant cavities, 3 rectangular supporting columns, 4 sound-producing tubes, 5 positioning ribs, 6 arc-shaped protrusions and 7 installation cavities.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

The casing suitable for automatic assembly and positioning as shown in fig. 1 and 2 comprises a tubular casing 1, wherein a sounding resonant cavity 2 is arranged at the lower part of the casing 1, an installation cavity 7 for assembling a buzzer component is arranged at the upper part of the casing 1, six rectangular support columns 3 protruding inwards are uniformly distributed on the inner wall of the casing 1 where the sounding resonant cavity 2 is located in the circumferential direction, the buzzer component can be arranged on the rectangular support columns 3 to be positioned during assembly, a sounding pipe 4 located in the sounding resonant cavity 2 is arranged at the center of the inner bottom surface of the casing 1, a sounding hole of the sounding pipe 4 is communicated with the sounding resonant cavity 2 and the outside, an arc-shaped protrusion 6 is arranged at the edge of the upper end surface of the casing 1, and the casing is convenient to be assembled and connected with an upper cover through the matching of the arc-shaped protrusion 6 and a clamping.

The inner wall of the shell 1 where the sounding resonant cavity 2 is located is provided with a positioning rib 5, the length direction of the positioning rib 5 points to the center of the shell 1, and the positioning rib 5 is located between the two rectangular pillars 3.

The utility model discloses a set up location muscle 5 on 1 inner wall of casing, arrange the cover shell on the automatic line with location muscle 5 as the benchmark when the assembly to reach that the position is unified, assemble accurate purpose, alleviate operation intensity and improve the operating efficiency simultaneously.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
