Description

Technical Field

[0001] The utility model relates to a terminal pressing jig for a car audio basin frame. Background Art

[0002] With the rapid development of the automobile industry, there are more and more car styles, and the car audio styles installed on the car are also changing with the development of the automobile industry. In particular, as an injection molded part, the structural differentiation of the audio basin is getting bigger and bigger. Many types of car audio basins need to cooperate with press-fit terminals or welding pieces and other components. In order to improve production efficiency, some press-fit tooling for car audio basin terminals or welding pieces has also appeared in the prior art. For example, the Chinese utility model patent with the authorization announcement number CN211138182U discloses a fixture for pressing the car audio speaker terminal into the car audio basin, but the device starts the cylinder to drive the pressure block downward to press the car audio basin, thereby completing the terminal press-fitting work. For example, a Chinese utility model patent with authorization announcement number CN207802382U discloses a device for pressing a speaker basin frame and a welding piece. When working, the speaker basin frame is installed on the basin frame positioning support plate, and the welding piece is inserted into the jack on the welding piece mounting part of the speaker basin frame. When the upper template moves downward along the guide column, the upper mold basin frame pressing block module presses the speaker basin frame, drives the speaker movable basin frame and the basin frame positioning support plate to move downward and compress the reset spring, and the top of the lower mold welding piece bracket is supported by the bottom of the welding piece mounting part of the speaker basin frame, and the upper mold welding piece pressing block presses the top of the welding piece, so as to press the welding piece into the jack on the welding piece mounting part of the speaker basin frame.

[0003] However, the above-mentioned press-fitting jigs all utilize a pressing block to directly contact the sound basin frame to complete the press-fitting. It is found in actual production that once the press-fitting pressure is improperly controlled, it is easy to cause the basin frame to be crushed, especially some basin frames with relatively thin shell thickness. Utility Model Content

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0010] A support positioning groove is provided on the lower side of the base, a support positioning flange is provided at the lower end of the elastic rod support, and the support positioning flange is arranged in the support positioning groove and is limited in downward displacement by a lower fixing plate, and the lower fixing plate is fixed to the base by a lower fixing bolt.

[0011] A pressure rod positioning groove is provided on the upper side of the pressure plate, a pressure rod positioning flange is provided on the upper end of the pressure rod, and the pressure rod positioning flange is arranged in the pressure rod positioning groove and is limited in upward displacement by an upper fixing plate, and the upper fixing plate is fixed to the pressure plate by an upper fixing bolt.

After the lower fixing plate 802 is disassembled, the elastic rod support 8 can be pulled out downward and replaced with an elastic rod support 8 of a suitable length according to actual needs. In this way, on the one hand, the lifting height of the elastic support rod 6 can be adjusted according to actual needs, and on the other hand, the elastic support rod 6, spring 7 and other components of a suitable length can also be replaced according to actual needs to meet the press-fitting needs of car audio basin racks 13 of different models and heights.

[0030] The utility model designs the pressure rod 5, the elastic support rod 6 and the elastic rod support 8 as replaceable structures. In addition to meeting the press-fitting requirements of car audio basin frames 13 of different models and heights, it can also ensure that the pressure plate 4 does not directly contact the car audio basin frame 13, thereby avoiding problems such as basin frame damage due to press-fitting pressure imbalance.
