Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing equipment, and particularly relates to a processing device for characteristic holes on the conical surface of a conical cap. Background Art

[0002] In the mechanical field, the main reasons for threading cone caps include the following: 1. Improving connection strength: The threaded hole design increases the contact area between the cone cap and the connected component, thereby enhancing the stability and strength of the connection. Through the interlocking action of the threads, threaded connections evenly distribute external forces and torques over a larger area of ​​the cone cap, avoiding damage at a single stress point and improving the overall load-bearing capacity. 2. Ease of installation and removal: The threaded hole design makes installation and removal of cone caps easier. Threaded connections allow cone caps to be easily tightened or loosened using a wrench or other tool, without the need for specialized tools or complicated procedures, improving work efficiency and ease of maintenance. 3. Standardization and versatility: The threaded hole design facilitates standardization and versatility of cone caps. Cone caps produced by different manufacturers that meet the same thread standards are interchangeable, improving equipment compatibility and ease of maintenance. 4. Adapting to diverse connection requirements: The threaded hole design can be adapted to meet diverse connection requirements. By choosing different thread sizes and types, different fastening requirements and working environments can be met, ensuring a reliable and secure connection. In summary, drilling threaded holes on the conical surface of the cone cap not only improves the strength and stability of the connection, but also facilitates installation and disassembly, increases standardization and versatility, and meets different connection requirements.

[0003] The cone cap 1 structure in the prior art is as follows Figure 3-4 As shown, the threaded hole 11 to be processed is on the first inclined surface 10 and has a fixed position relationship. Therefore, it is particularly important to confirm the axial position and the circumferential position. The existing processing method is to realize the processing of the threaded hole 11 by clamping the dividing head, that is, the center of rotation of the dividing head is rotated to an elevation angle of 30° with the horizontal position. When the outer circle 12 is clamped by the clamping claw, the cone surface busbar at the highest position is horizontal, which is also the busbar position where the threaded hole 11 is located. The main shortcomings of the current processing method are: in the axial direction, the length of the workpiece and the clamping position of the workpiece will cause the dimensional fluctuation of the axial position, and single-piece measurement and alignment are required; in the circumferential direction, the workpiece cannot be quickly placed at the required angle, and the first positioning hole 13 needs to be repeatedly leveled. In order to solve the existing problems, it is necessary to design a processing device that is convenient for determining the inherent position relationship of the threaded hole 11.
