Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a tool magazine mechanism for a drilling and tapping center. Background Art

[0002] The drilling and tapping center is a CNC machine tool with a higher degree of automation. It can combine multiple processes such as milling and drilling, and cut and shape multiple processes at one time. It has a very high degree of automation. When manufacturing and processing equipment, such as injection molds, it is necessary to drill, tap and mill a large number of through holes, blind holes, threaded holes, stepped countersunk holes, grooves of various shapes, tenons, mortises and slide rails, slide grooves and other hole-groove-mortise-and-tenon structures on the workpiece.

[0003] The tool magazine mechanism of the existing drilling and tapping center has a variety of tool feeding methods. When feeding the tool, the disc-type tool magazine will rotate to the tool feeding position after reaching the specified position through the rotating tool holder, so as to facilitate the grasping mechanism to grasp the tool body to complete the tool change. However, in the actual operation process, the rotating disk is prone to errors during the rotation process, so that the rotating tool holder cannot be accurately rotated to the tool feeding position, resulting in deviations when feeding the tool. If the staff cannot handle it in the first time, not only the grasping mechanism cannot accurately grasp the tool body, but also it is easy to damage the processing tool body and cause unnecessary losses. In addition, the tool bodies on the tool magazine are exposed to the outside world, which is very dangerous. To this end, we propose a tool magazine mechanism for a drilling and tapping center.

[0007] Furthermore, a visual window is inlaid and connected on the surface of the protective cover.

[0008] Furthermore, a rotating seat is rotatably arranged inside the tool magazine disc, and a plurality of drill seats are rotatably connected to the surface of the rotating seat.

[0009] Furthermore, a fixed shaft is detachably connected to the side of the shell facing the tool magazine disc, a transmission rod is rotatably connected to the inner cavity of the fixed shaft, and the end of the transmission rod passes through the tool magazine disc and extends to the inside to be detachably connected to the back of the rotating seat.

[0010] Furthermore, a second transmission gear is fixedly connected to an end surface of the transmission rod close to the fixed shaft.

[0011] Furthermore, a servo motor is embedded and connected on the back of the shell, and a power output end of the servo motor passes through the shell and extends to the other side of the shell.
