Description

Technical Field

[0001] The invention relates to the technical field of large-diameter end gear processing, in particular to a tool for internal and external fixing of large-diameter end gear. Background Art

[0002] The end gear disc, also known as the hickey disc or end face gear disc, is the most core and critical component of mechanical indexing equipment. It can ensure the high-precision indexing and orderly operation of CNC machinery and other equipment. The manufacturing precision of the end gear disc is high and the process is complex. In recent years, with the advancement of CNC technology and the general improvement of the degree of automation, the production and application of machining center machine tools, CNC lathes, and CNC milling machines have become increasingly widespread, and the demand for high-precision and high-efficiency indexing devices has also become increasingly greater. Among them, the indexing device using the hickey disc end face gear disc accounts for a large proportion. The characteristics of this indexing table are positioning with a fixed value, simple structure, good positioning rigidity, high repeatability and indexing accuracy, and fast positioning speed. It is widely used in various processing and measuring devices, such as the hickey disc indexing workbench with pallet exchange in the horizontal machining center, which realizes accurate positioning and indexing rotation through the engagement of the upper and lower hickey discs.

[0003] When the existing tooling for fixing the internal and external ends of large-diameter end teeth is in use, application number CN202310656606.X provides a tooling for fixing the internal and external ends of large-diameter end teeth, including an end tooth clamping structure, which includes a movable frame, the through hole at the bottom of the movable frame cooperates with the transmission screw, and fitting grooves are provided on both sides of the bottom of the movable frame, the fitting grooves are slidably connected to the frame rod, a connecting pipe is provided on the outer wall of one side of the fitting groove, and a liquid outlet groove is provided on the outer wall of the other side of the movable frame, and the interior of the movable frame is connected to the connecting pipe. The present invention provides an end tooth clamping structure, and during the process of clamping the end teeth, a liquid outlet groove is provided on the top of the inner side of the movable frame, which can evenly spray the coolant onto the processed surface of the end teeth. At the same time, the liquid outlet groove is inclined and a rotating plate is provided inside. The rotating plate blocks the coolant so that the coolant can be evenly sprayed onto the surface of the end teeth, so that the overall temperature difference of the end teeth is small, and thermal deformation of the end teeth is avoided during the fixed processing inside the tooling. However, in the above technology, when the product needs to be cooled, it needs to be turned over and then sprayed. In this way, the spraying of coolant can easily cause structural damage to the product in this process. For this reason, we propose a tooling for internal and external fixation of large-diameter end teeth to solve the above problems. Summary of the Invention
