The utility model relates to a hole milling chiseling machine, and belongs to the technical field of engineering construction. Comprising a machine body and a crawler-type chassis assembly, crawler wheel assemblies are arranged on the two sides of the crawler-type chassis assembly, a power assembly is integrated on the machine body, a platform lifting adjusting device for driving the construction platform to ascend and descend is installed on the front side of the machine body, and the platform lifting adjusting device is connected with the crawler-type chassis assembly. And the milling chiseling head assembly is mounted on the construction platform through the mechanical arm assembly. The hole milling and chiseling machine has the advantages that the mechanical arm assembly is additionally arranged, the work freedom degree of the milling and chiseling head assembly can be expanded, the limitation of single-freedom-degree work of traditional chiseling equipment is broken through, the mechanical arm assembly is matched with the platform lifting adjusting device in a cooperative mode, and the work flexibility of the hole milling and chiseling machine is improved. A hole to be chiseled can be manually and rapidly positioned, manual adjusting time is shortened, chiseling work is completed through a simple mechanical structure, time and labor are saved, stability is good, operation is convenient, and mass production can be achieved.

This application relates to the field of machining technology and discloses a horizontal milling machining center, including a first guide rail, a second guide rail, and a tray. A milling body is mounted on the first guide rail, and a movable stage is mounted on the second guide rail. The movable stage is rotatable and used to fix the workpiece to be machined. The tray is detachably mounted on the movable stage. This horizontal milling machining center uses vertical and horizontal linear motion instead of traditional arc-shaped rotary motion to achieve tray exchange. Combined with an anti-contamination conical positioning structure and the significant differences in tray positioning states, it fundamentally solves the defects of existing technologies such as easy collisions during tray exchange, unstable positioning accuracy, and poor sensor reliability.
