Problems solved by technology

The spring pin type tool changing manipulator has the following defects in use: one is that the manipulator actively grabs the tool, and the grasping force is insufficient; the other is that the manipulator relies on the elastic force of the spring for self-locking, and the self-locking performance is poor. The manipulator will drop the tool or the tool will be thrown out during the tool change rotation process; the third is that the manipulator needs the spindle and the tool magazine to move to the specified position before the manipulator can rotate to the tool change position and grab the knife, which requires a certain amount of movement Time, so the accuracy of movement in place is poor

Embodiment Construction

[0021] It includes the main body of the manipulator (1) and the jaws (8). The jaws (8) are arranged in pairs on the main body (1) of the manipulator in the shape of jaws, and are supported by the pivot pin (7) as a movable joint; the whole manipulator device is 180°circumferential symmetry, and fix it to the main transmission shaft (20) through the manipulator main body (1), so that the entire manipulator device can not only rotate along the main transmission shaft (20) circumferential direction, but also along the main transmission shaft ( 20) Axial forward and backward movement, characterized in that: the main body (1) of the manipulator is also equipped with a push rod mechanism, a spring clamping mechanism and a locking mechanism, which are located in the middle, rear and inside of the jaw (8) in sequence. The tail part; the middle part of the jaw (8) is provided with a waist-shaped hole (19) associated with the sliding pin (6) in the ejector mechanism, and the tail is prov...

Abstract

The invention relates to an interlocking type tool changing mechanical arm device which comprises a mechanical arm body, a claw, an ejector rod mechanism, a spring clamping mechanism and a locking mechanism. The ejector rod mechanism is composed of an ejector rod (11), a U-shaped fork (12) and a spring (5). A slide pin (12) slides in a kidney-shaped hole (19) of the claw (8) so as to push the claw (8) to be opened and closed. The spring clamping mechanism and the locking mechanism are arranged at the tail portion of the claw (8). According to the driven type tool clamping mechanism arm, the ejector rod (11) is triggered by a tool to push the claw (8) to be opened or closed, automatic interlocking is achieved through the locking mechanism when the tool is clamped, the claw is effectively prevented from getting loose, and the tool is prevented from falling and being thrown away; a main shaft and a tool magazine directly push the tool into the mechanical arm, the tool changing time is saved, and work efficiency is high.

Description

technical field [0001] The invention relates to a manipulator tool changing system for combined machine tool components, in particular to an interlocking tool changing manipulator device. Background technique [0002] The tool changing manipulator is an important part of the machine tool, and it is a device for exchanging the tool on the spindle and the tool in the tool magazine. What manipulator generally adopts at present is spring pin type tool change manipulator, and it adopts the structure of spring pin to lock tool. The spring pin type tool changing manipulator has the following defects in use: one is that the manipulator actively grabs the tool, and the grasping force is insufficient; the other is that the manipulator relies on the elastic force of the spring for self-locking, and the self-locking performance is poor. The manipulator will drop the tool or the tool will be thrown out during the tool change rotation process; the third is that the manipulator needs the ...
