Description

Technical Field

[0001] The invention belongs to the technical field of mechanical processing equipment, and in particular relates to a lateral drilling device for a transmission frame of a construction elevator. Background Art

[0002] The transmission frame is an important component in the transmission system of the construction hoist. In the transmission system of the construction hoist, the drive motor equipped with gears is installed on the transmission frame. The lifting and lowering of the construction hoist is realized by meshing with the rack on the standard section. The transmission frame is connected to the cage through a pin shaft. The transmission frame is also connected to the drive motor and the cage. This feature determines that the manufacturing and processing of the transmission frame has high precision requirements. After the welding, there are eight holes on the side of the transmission frame that need to be drilled. Generally, when drilling holes on the transmission frame after welding, a high-precision CNC boring and milling machine is used to ensure the processing accuracy of the transmission frame. However, when using a CNC boring and milling machine to drill holes on both sides of the transmission frame, it is necessary to process each hole one by one, and it is also necessary to flip the transmission frame and repeatedly clamp it, which is time-consuming and labor-intensive, with low efficiency, and it is also difficult to ensure the shape and position tolerances of the holes on both sides.
