DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0016] Reference Figure 1 and Figure 2 A tool magazine tool changing mechanism for use with a tool magazine tool changing system, comprising a tool magazine 1 and a tool changing assembly 2 provided on the tool magazine;

[0017] The knife-beating assembly 2 includes a mounting plate 21 provided on the tool magazine, a servo screw motor fixing plate 22 provided on the mounting plate, a servo screw motor 23 installed on the servo screw motor fixing plate, a movable plate 26 mounted on the driving end of the servo screw motor through a linear bearing flange 24 and a linear bearing 25, and a tool sleeve clamping block 27 installed at the bottom of the movable plate;

[0018] In order to facilitate telescopic movement, guide rods 3 are installed at both ends of the servo screw motor fixed plate 22 through self-lubricating bearings 31. The guide rods 3 on both sides are respectively inserted into the movable plate 26. When the movable plate 26 is driven to move up and down, it can move up and down along the guide rods 3, thereby playing an auxiliary role.

[0019] In order to prevent the servo screw motor 23 from failing to lock the internal ejection mechanism after being disconnected, an electronic lock 4 is provided at the driving end of the servo screw motor 23, and the electronic lock is provided at the bottom of the servo screw motor fixing plate 22. Under normal power-on state, the electronic lock is not locked. When the power is cut off or several units stop, the electronic lock is locked, and the locking end of the electronic lock extends to hold the driving end of the servo screw motor to prevent it from falling, thereby playing a protective role.

[0020] In order to ensure whether the servo screw motor 23 is extended and retracted into place and whether the knife cup can be moved down, a sensor assembly 5 is provided on the upper and bottom parts of one side of the mounting plate 21. The sensor assembly 5 includes a sensor mounting frame 51 mounted on the fixed plate 21 and a sensor 53 mounted on the fixed mounting frame 51 through a fixing nut 52. The upper sensor is used to sense whether the servo screw motor 23 is reset into place, and the bottom sensor is used to detect whether the servo screw motor 23 is extended into place, so as to ensure that the knife cup of the tool magazine can be moved into place.

[0021] The benefits of the present invention are that the present technical solution realizes electronic control by setting up a new knife-beating mechanism and adopting a servo screw motor to drive, thereby simplifying the system, eliminating the cylinder drive, and saving a set of air compressor equipment. In addition, the present structure has a small size, large torque, and high stability, which reduces the cost of equipment operation.

[0022] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
