Power head for digital control hole drilling

Abstract

The invention discloses a power head for digital control hole drilling, which comprises a shell, a main shaft arranged on the shell, a main shaft drive system connected with the main shaft, a power tooth drive system and a digital controller, wherein the power tooth drive system is connected to the main shaft; the main shaft is connected with the main shaft drive system through an axial flexible connection mechanism; and the digital controller is connected with the main shaft drive system and the power tooth drive system through conducting wires respectively. The power head makes the main shaft realize axial feeding in the process of rotating by using the power tooth drive system to avoid abuses caused by the manual feeding or the feeding depending on a leading screw in the past. The overall structure of the power head is simple to operate and is convenient to mount and dismount, the processing noise is low, the replacement and the debugging are easy, and a servo motor controlled by the digital controller improves the processing precision and the processing accuracy; besides, the power head has a wide application range, and provides a good start for later total digitalization and automation.

Description

technical field [0001] The invention relates to a hole processing device, which belongs to the field of mechanical processing, in particular to a numerically controlled drilling power head capable of sequentially completing drilling and tapping with high precision. Background technique [0002] The technical inadequacies of the hydraulic drilling and tapping power heads commonly used in the market are mainly reflected in the following aspects: [0003] 1. In terms of operation, the common drilling and tapping power head has a split structure. When the workpiece is processed, it needs to carry out two processes of drilling and tapping separately, which cannot be effectively integrated, which is inconvenient to use and labor-intensive. For ordinary operators, it will also bring other technical problems in use, such as installation and debugging of equipment. [0004] 2. In terms of processing accuracy, the processing accuracy of ordinary drilling and tapping power heads is ma...

Problems solved by technology

[0005] 3. In terms of structure and principle, the structure of the ordinary drilling power head is that the three-phase asynchronous motor drives the main shaft to rotate, and the hydraulic cylinder drives the main shaft barrel to feed. It is necessary to add a hydraulic station for the equipment to work, and the equipment cost is high.

The tapping power head is guided by the tapping lead screw to complete the tapping action. When processing products with different pitches, it is necessary to replace the corresponding tapping guide screw to complete the operation, resulting in poor versatility and low efficiency of the ordinary drilling power head.
