Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a special fixture for machining a swing angle milling head. Background Art

[0002] Since the swing milling head box is composed of multiple holes and planes, it has the characteristics of high requirements for overall motion positioning accuracy, form and position tolerances of each hole system and surface, and dimensional accuracy. It is not suitable for designing casting process umbilical auxiliary clamping (because the removal of the process umbilical after fine machining will cause stress changes, which will change the adjacent related dimensions, resulting in form and position tolerances and accuracy deviations).

[0003] The existing utility model patent application, CN202021718984.4, proposes a special fixture for machining angular milling heads, belonging to the field of mechanical technology. The advantages of this utility model are: good overall consistency in the final finishing of the box, minimal stress and deformation, and improved dimensional accuracy and overall geometric tolerances, with significant results.

[0004] In the above patent, the box body is installed inside the device through cylindrical pin holes and threaded holes. After the threaded holes are aligned with the screw connection holes, multiple screws need to be rotated for connection. The operation is cumbersome, which increases the time cost and reduces the practicality of the device. Therefore, a special fixture for processing an angular milling head is provided to solve the above problems. Utility Model Content

[0011] Preferably, a telescopic spring is fixedly connected to the interior of the second slide groove, and the telescopic spring is fixedly connected to the limit plate. Under the elastic force of the telescopic spring, the limit plate pushes the card block into the interior of the card slot, thereby limiting and fixing the limit block.

[0014] The utility model provides a special fixture for machining an angular milling head. Compared with the existing technology, it has the following advantages:
