Description

Technical Field

[0001] The utility model belongs to the technical field related to the processing of flange forks, and specifically relates to a drilling fixture for a flange plate of a flange fork. Background Art

[0002] The flange fork is an important component on the automotive drive shaft. Its main function is to connect the transmission and the drive axle and bear high-speed transmission. It is a part with a relatively complex shape, and its structure and processing technology directly affect the performance of the part, and further affect the effect of the power transmission of the whole vehicle. Since the drive shaft is a rotating body with high speed and few supports, the dynamic balance of the flange fork is crucial to ensure its efficient and safe operation. When drilling on the flange plate of the flange type flange fork, one end of the flange plate is the flange fork structure. When using the flange fork structure as the positioning support surface, there is no effective support plane. Using height setting for support requires repeated adjustment of the support height of the height setting to ensure that the flange surface is in a horizontal state. The adjustment process takes a long time and has high requirements for the operator's operation skills. When the flange plate plane is placed horizontally as the reference plane, during the drilling process, affected by the flange fork structure, the main shaft of the drilling machine will interfere with the flange fork structure. Therefore, it is necessary to use an extended drill bit. Due to the poor rigidity of the extended drill bit, the drill bit may break during the drilling process, resulting in high processing costs, low processing efficiency, and difficult guarantee of the drilling quality of the product.

[0003] In view of this, the present utility model is specifically proposed. Content of the Utility Model
