Multi-shaft synchronous torque transmission head

Abstract

The invention discloses a multi-shaft synchronous torque transmission head. The multi-shaft synchronous torque transmission head comprises a spindle head arranged at the Z axis of a drilling machine, the spindle head comprises four rotation main shafts arranged in the same horizontal line with equal intervals, two horizontal support frames arranged in parallel, a vertical fixing plate, and four transmission heads, the two support frames are both provided with penetrating holes penetrating through the four rotation main shafts, a bearing matched with the rotation main shaft is arranged in each penetrating hole, side edges of the two horizontal support frames are both fixedly arranged on the surface of the vertical fixing plate via screws, the four transmission heads are fixedly arranged at the bottom ends of the four rotation main shafts via hexagon nuts, a synchronous belt and a synchronous wheel matched with the synchronous belt are arranged on each two adjacent rotation main shafts positioned between the two horizontal support frames in a sleeved manner, the number of the synchronous wheels is six, and the synchronous wheels are all arranged on the rotation main shafts. According to the multi-shaft synchronous torque transmission head, the transmission is realized via the synchronous wheels and the synchronous belts, the transmission precision is reached, and noises are reduced.

Description

technical field [0001] The invention relates to the technical field of numerical control drilling machines, in particular to a multi-axis synchronous torque transmission head. Background technique [0002] The traditional CNC drilling machine is equipped with a detachable and replaceable drill bit. To process holes with multiple specifications, it needs to be replaced one by one before processing. Not only the production efficiency is low, but also the labor intensity of the workers is large, and the processing accuracy is difficult to guarantee. And the existing ones all adopt gear transmission, but they have gaps, cannot meet the precision requirements, and the noise is relatively large. Contents of the invention [0003] In order to solve the above technical problems, we propose a multi-axis synchronous torque transmission head that can save manpower, increase work productivity and ensure machining accuracy. [0004] To achieve the above object, the technical scheme of...

[0002] The traditional CNC drilling machine is equipped with a detachable and replaceable drill bit. To process holes with multiple specifications, it needs to be replaced one by one before processing. Not only the production efficiency is low, but also the labor force is high, and the processing accuracy is difficult to guarantee.

Moreover, the existing gears are used for transmission, but they have gaps, which cannot meet the accuracy requirements, and the noise is relatively large
