Multi-axis quick-change drill bit assembly structure and quick-change method for drilling holes in conveyor belts

Abstract

The invention discloses a multi-shaft quick replacing drill bit assembly structure for punching a conveyor belt and a quick replacing method. A spindle box is arranged between an upper bottom board and a lower bottom board and can move up and down along a guide column. An oil cylinder joint of a hydraulic oil cylinder is fixedly connected to the upper end of the spindle box, so that the spindle box is driven to move up and down. A motor is arranged above the outer portion of the spindle box, an output shaft of the motor is perpendicularly downward and is fixedly connected with the upper ends of output shafts of the spindle box, the lower end of each output shaft of the spindle box is connected with the upper end of a drill bit spindle through a cross universal joint, the lower end of each drill bit spindle is connected with a drill bit, the upper end of each drill bit spindle is connected with a drill bit support, the drill bit support is fixedly connected to the bottom of the spindle box through guide screws, and a limiting clamping board is arranged on the front side of the drill bit support. Multiple rectangular grooves correspondingly matched with the drill bit support are formed in the lower end of the limiting clamping board at intervals. The machined hole distance can be adjusted according to the requirements and the requirements for machining holes of various distances and distance arranging holes can be met.

Description

technical field [0001] The invention relates to a tool for processing through holes for various conveyor belts, in particular to a drill assembly structure specially used for drilling holes in conveyor belts. Background technique [0002] For the bucket elevator used in the grain industry, the lifting belt and the conveyor belt are important conveying parts. Generally, scrapers, buckets and other accessories are installed on the surface of the lifting belt and the conveyor belt, so it is necessary to process on the lifting belt and the conveyor belt. Accessory installation through holes for various specifications of row spacing and bucket spacing. At present, these mounting through holes are all processed on a punching machine and formed by punching. However, since the inside of products such as lifting belts and conveyor belts is an integral fabric core layer, the quality is soft and the elongation is relatively large, so when the through holes are stamped and installed, t...
