[0004] The utility model aims at providing a kind of microphone wire welding fixture to solve the problems raised in the above background.

[0005] To achieve the above object, the utility model adopts the following technical scheme:

[0006] A kind of microphone wire welding fixture, including upper fixture and lower fixture, the two ends of the upper fixture and lower fixture are connected by adjusting bolt, the inside of the upper fixture is provided with upper cavity, the inside of the lower fixture is provided with lower cavity, the side, away from the lower cavity of the upper cavity, is provided with filling cavity, the inside of the filling cavity is filled with silica gel column.

[0007] By adopting the above technical scheme: when processing, multiple microphones are placed between upper cavity and lower cavity, then fixed by adjusting adjusting bolt, and the microphone is reinforced by the silica gel column filled in the inside, and the upper cavity is protected, to avoid direct contact between microphone and upper cavity, so as to ensure the processing precision of product, and the service life of fixture can be improved.

[0008] Preferably, the upper fixture and the lower fixture are provided with buffer spring between the upper fixture and the lower fixture, the buffer spring is sleeved on the outside of the adjusting bolt.

[0009] By adopting the above technical scheme: by buffer spring, the upper fixture and the lower fixture can be separated conveniently during the removal of fixture.

[0010] Preferably, the upper fixture and the lower fixture are provided with guide column between the upper fixture and the lower fixture, the guide column is located on one side of the adjusting bolt.

[0011] By adopting the technical scheme, the guide column can ensure the stability of the adjustment between the upper clamp and the lower clamp and the stability of clamping the multiple microphones.

[0012] Preferably, the height difference between the upper clamp and the upper cavity and the height difference between the lower clamp and the lower cavity exist, and the height difference between the upper clamp and the upper cavity and the height difference between the lower clamp and the lower cavity are between 0.07-0.13mm.

[0013] By adopting the technical scheme, the height difference between the upper clamp and the upper cavity and the height difference between the lower clamp and the lower cavity can ensure that the upper cavity and the lower cavity are not easy to directly contact with the outside during use and storage, reduce abrasion, and further improve the service life of the clamp.

[0014] The technical effects and advantages of the utility model are as follows:

[0015] The clamp can avoid abrasion during use and storage of the upper cavity and the lower cavity, can ignore the tolerance of the microphone shape, improve production efficiency, and ensure machining precision. DRAWINGS
