Description

Technical Field

[0001] The utility model relates to the technical field of coupling processing, in particular to a drilling device for producing universal couplings. Background Art

[0002] A universal coupling is a mechanical transmission device used to connect two shafts, allowing them to rotate at different angles without affecting transmission efficiency. It usually consists of two bearing sleeves, two shaft sleeves and a coupling center, in which the bearing sleeves are connected to their respective shafts and the shaft sleeves are connected through the coupling center, so that torque can be transmitted between the two shafts and the shafts can move at different angles.

[0003] A Chinese patent discloses a drilling device for processing a cross-axis universal coupling (publication number: CN220330640U). Under the interaction of a processing plate, a cross-axis universal coupling part, a lifting cylinder, a drilling machine, a bidirectional threaded rod, an interlaced helical gear, a servo motor and a limit arc block, the device sets the cross-axis universal coupling part between a plurality of limit arc blocks, and uses a servo motor to drive the bidirectional threaded rod to drive the plurality of limit arc blocks to fix the cross-axis universal coupling part, so as to facilitate the drilling machine to drill holes on the top of the cross-axis universal coupling part. However, the device still has the following problems:

[0004] Although the above device can fix the coupling by the limit arc block, a large amount of debris will be generated when drilling the coupling. These debris adhere to the gap between the two-way threaded rod and the staggered bevel gear at the bottom and are not easy to clear out. In addition, if a large amount of debris is blocked on the surface of the two-way threaded rod and the staggered bevel gear, it may affect the transmission and further affect the clamping of the coupling by the limit arc block. Therefore, a drilling device for the production of universal couplings is proposed to solve the above problems. Utility Model Content
