Embodiment Construction

[0016] Such as figure 1 , 2 Shown: 1 is the fixed claw, 2 is the movable claw. The middle part of the fixed claw 1 and the movable claw 2 is rotationally connected by a pin shaft 4. The specific connection method is that there are symmetrical fixed claw pin holes 14 on both sides of the middle part of the fixed claw 1, and there are movable claw pin holes 26 in the middle of the movable claw 2, and the movable claw 2 Located in the middle, the pin shaft 4 is inserted in the pin hole 14 of the fixed claw and the pin hole 26 of the movable claw, and the end is equipped with an axially limited jacking screw 3 that is also threaded with the fixed claw 1, so that the movable claw 2 can be fixed relative to the fixed claw. The claw 1 rotates at a certain angle.

[0017] Such as image 3 , 4 , Shown in 5: a first spring abutment 15 is arranged at one end of the fixed claw 1. The other end of the fixed claw 1 is arc-shaped fork and has a protrusion 13 matching the groove on the o...

Abstract

The invention provides a self-locking cutter quick exchange device which comprises a fixed claw and a movable claw. The middle of the fixed claw and the middle of the movable claw are in rotatable connection through a pin roll. A spring is arranged between one end of the fixed claw and one end of the movable claw, the other end of the fixed claw is of an arc-shaped fork shape, and a protrusion which is matched with a groove in the outer periphery of a cutter handle is arranged on the inner side of the other end of the fixed claw. The other end of the movable claw is provided with a hanging claw which is matched with a groove in the end face of the cutter handle and an anti-rotating boss which is matched with the an anti-rotating groove which is formed in the end face of the cutter handle, a collision head is arranged on the side face of the movable claw, and the collision head extends to the other side from a center hole in the fixed claw (1). According to the self-locking cutter quick exchange device, the cutter exchange time is short when a cutter is exchanged, the auxiliary time is shortened, the working efficiency is improved, the structure is simple due to few parts, the occupied space is small, and breakdowns can not happen easily.

Description

technical field [0001] The invention relates to a tool changing device, in particular to a self-locking tool quick changing device for machining equipment. Background technique [0002] At present, the automatic tool changing device in the metal cutting machine tool is composed of a tool clamping device and a tool changing device. Compared with the cutting time, the tool change time is longer, and the failure rate is high, and it takes up a lot of space. Contents of the invention [0003] The object of the present invention is to provide a self-locking tool rapid exchange device with few components, simple structure, small space occupation, flexible and reliable action, and short tool exchange time, so as to overcome the deficiencies of the prior art. [0004] The self-locking tool quick exchange device of the present invention includes a fixed claw and a movable claw, and the middle parts of the fixed claw and the movable claw are rotatably connected by a pin; a spring i...
