Description

Musical instrument welding fixture Technical Field The utility model belongs to the technical field of musical instrument manufacturing, and particularly relates to a musical instrument welding fixture. Background The main products of the musical instrument production industry are basically musical instruments related to the musical community, namely instruments for carrying out music art recreations, and the production of the musical instruments is different from that of general industrial products. It requires not only a reasonably fine look of the product, but also good acoustic qualities including tone, music and a defined level of sound. Therefore, the selection of materials is very strict. The utility model provides a motormeter dish support welding position frock that discloses in patent CN213196279U relates to the panel board support and welds technical field, comprises a workbench, one side fixedly connected with motor of workstation, the first bevel gear of fixedly connected with on the top output shaft of motor, one side swing joint of workstation has the connecting rod, the one end fixedly connected with second bevel gear of connecting rod, first bevel gear passes through second bevel gear transmission with the connecting rod and is connected, the other end fixedly connected with third bevel gear of connecting rod, the bottom one end fixedly connected with telescopic column of workstation.
