[0029] Refer to Figures 1 to 3The shown one is used for the fixed jig of automobile valve chamber cover ultrasonic welding, including base 10, top seat 20, fixed mode 30 and welding head 40, the top seat 20 can be lifted and be slid on the guide column 21 on the base 10, the welding head 40 is installed on the side of the top seat 20 close to the base 10, the fixed mode 30 can be detachably installed on the area of the base 10 under the welding head 40 and can be adapted with the welding head 40, the fixed mode 30 is used to carry and fix the valve chamber cover, the base 10 is provided with several fine adjustment mechanisms 50 on the circumferential side of the fixed mode 30, and the fine adjustment mechanism 50 is used to adjust the position of the fixed mode 30 on the base 10.

[0030] Specifically, the base 10 and the top seat 20 can be opened and closed with each other, which can be respectively installed in the rack structure in the similar patent CN202323574249.7-a HPD power module ultrasonic welding jig or CN202322580451.4-ultrasonic welding machine. The fixed mode 30 in the application is a replaceable structure, and different fixed modes 30 can be adapted to different valve chamber covers to improve adaptability. The main function of the fine adjustment mechanism 50 is to adjust the position of the newly installed fixed mode 30 relative to the welding head 40. Although the welding head 40 can also be replaced in the application, in the actual use process, the welding head 40 is generally fixed first, then the fixed mode 30 is installed, and finally the relative position of the fixed mode 30 and the welding head 40 is adjusted by the fine adjustment mechanism 50. This can quickly adjust and ensure the welding precision in the later period. In addition, the welding head 40 is connected to the external ultrasonic welding equipment in the application, so in the actual use process, the ultrasonic welding equipment can also be directly fixed on the top seat 20, or can be separately external. The ultrasonic welding equipment is a prior art device, and the application does not describe it in detail. The technology in patent CN202021926239.9-a ultrasonic welding machine can be used.

[0031] In the above embodiment, in order to facilitate fixing and installation, the base 10 is provided with several movable sleeves 13, and the guide column 21 is inserted on each movable sleeve 13, and the top seat 20 is movably inserted on all guide columns 21. Similarly, the top seat 20 is also provided with a sliding sleeve structure similar to the movable sleeve 13, which is not described in detail in the application. In the embodiment of the application, in order to facilitate lifting the entire jig, the base 10 is provided with a handle on both ends.

[0032] The utility model discloses a fixed jig for automobile valve chamber cover ultrasonic welding designs a can open and close base 10 and top seat 20, so as to facilitate the external equipment to lift and drive fixed mode 30 and welding head 40 to be close to each other and weld the product, and the structure design can effectively guarantee the welding quality of product. The fixed mode 30 is used for bearing and fixing the valve chamber cover, can be adapted to the thin -walled product such as valve chamber cover, avoids the valve chamber cover deformation when the welding head 40 top pressure product, guarantees the welding quality. Meanwhile, fixed mode 30 can be detached relative to base 10, just need to replace fixed mode 30, simple and convenient. The position of fixed mode 30 on base 10 can be adjusted by fine adjustment mechanism 50, so that fine adjustment can be realized, the position of welding head 40 is adapted, and the welding precision of product is guaranteed.

[0033] Referring to Figures 1 to 3 , in order to facilitate installation and fixation, and adapt to different fixed mode 30, in an embodiment of the application, a plurality of mounting holes 11 are arranged on the base 10, and all the fine adjustment mechanisms 50 are detachably mounted in the corresponding mounting holes 11. The mounting holes 11 are arranged in a ring shape on the base 10 and can adapt to fixed mode 30 of different sizes. In addition, in the application, the fine adjustment mechanism 50 is provided with at least four groups, which are arranged around the fixed mode 30, and the opposite two fine adjustment mechanisms 50 cooperate with each other to press the opposite sides of the fixed mode 30.

[0034] Referring to Figures 1 to 2 , in an embodiment of the application, the fine adjustment mechanism 50 includes a limiting block 51, an adjusting bolt 52 and an adjusting nut 53. The limiting block 51 is detachably mounted on the mounting hole 11 by a screw. The limiting block 51 is provided with a insertion hole 54.
