Abstract

The invention provides a group hole drilling system. The system comprises drilling equipment and cutters; the drilling equipment is provided with a main shaft and a plurality of terminal output shafts in the vertical direction, and the terminal output shafts are arranged in one row and driven to link by the main shaft through a transmission device; the group hole drilling system is provided with a plurality of cutters, and the plurality of cutters are connected on different terminal output shafts respectively; and the cutter is provided with a twist drill cutter section, a hole expanding cutter section and a reaming cutter section. The system can process a row of straight-bottom and conical-upside holes processed by multiple processes and multiple cutters at one time, and has significance for processing products of large batch, high precision requirement and many hole positions; and the system can greatly reduce the moving and positioning frequency of workpieces and reduce the precision errors of products due to multiple clamping and multiple moving.

Description

technical field [0001] The present invention relates to drilling systems. Background technique [0002] With the deepening and development of China's economic reform, especially China's high-speed railway known as Airbus, its technology is already in the leading position in the world and will become a fulcrum to leverage the world economy. However, domestic anchorage products for prestressed tendons, which are required for the construction of high-speed railways and expressways, must break through the dilemma of low efficiency and high cost in order to meet the needs of going global. The technical problem that the position tolerance is difficult to control. [0003] The original production process of the anchor ring of the anchorage product group for prestressed tendon is: use the bar to cut into a round block with a sawing machine, process the blank into shape with a general car, and drill straight holes with a vertical drill. For example, 22 anchor rings with 22 holes are...
