Problems solved by technology

This type of tool changer generally has the following defects during use: (1) When grabbing and releasing the knife, the tool will collide with the movable pin at the buckle edge, which will not only produce metal impact sounds, but also cause the tool to collide with the movable pin. The wear, deformation and damage of the tool should not be too fast, which will affect the tool change speed; (2) The tool is clamped and locked only by one movable pin. If the movable pin fails, it will not work normally, and the equipment is safe. The operating coefficient is not high; (3) The locking of the tool is realized by the spring pushing the locking pin. If the spring of the locking pin is aged or broken, resulting in insufficient elasticity, it is easy to cause the tool to be unable to be locked and the tool to fall

Embodiment Construction

[0027] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0028] Please refer to figure 1 and figure 2 . An electromagnetic piston type tool changing device according to an embodiment of the present invention, such as figure 1 As shown, it includes the tool changing arm 1 and the tool changing hand 2. During the tool changing process, the tool changing arm 1 can rotate around the rotation axis at its center and move up and down. The two tool changing hands 2 are respectively located at the ends of the tool changing arm 1 At both ends, the tool changer 2 is used to hold the tool. Two ends of the tool changing arm 1 are respectively provided with a clamping hole, and a tool changing hand 2 is installed in the two clamping holes.

[0029] Such as figure 2 As shown, the tool changing hand 2 includes a clamping seat 21 , a...

Abstract

The invention provides an electromagnetic piston type tool changing device which comprises a tool changing arm for rotating, and a tool changing hand for clamping a tool. The tool changing hand comprises a clamping holder, an elastic piece, a piston, abutted-against pieces and an electromagnet; the clamping holder is arranged on the tool changing arm; multiple assembling holes are formed in the circumferential wall of the clamping holder in a penetrating way; the elastic piece, the piston and the electromagnet are arranged on the clamping holder in a sleeving mode; the position of the electromagnet remains stationary relative to the piston; two ends of the elastic piece are elastically abutted against the electromagnet and the piston; and the multiple abutted-against pieces are movably arranged in the multiple assembling holes in the clamping holder and are abutted against the piston. According to the electromagnetic piston type tool changing device, no impact happens during the tool changing process, and the tool is clamped by multiple independent parallel functional components, so that the safe operation factor is high; and a locking manner is changed, so that the occurrence of the phenomenon of tool falling can be effectively prevented.

Description

technical field [0001] The invention relates to the field of tool change in machining centers, in particular to an electromagnetic piston type tool change device. Background technique [0002] The tool changer is an important part of the machining center, and its function is to exchange the tool on the spindle with the tool in the tool magazine to realize the function of automatic tool change. At present, the tool changer holding the tool in the tool changing device generally adopts the spring pin type clamping method, and the principle is to use the spring to push the movable pin and the locking pin to realize the clamping and locking of the tool. This type of tool changer generally has the following defects during use: (1) When grabbing and releasing the knife, the tool will collide with the movable pin at the buckle edge, which will not only produce metal impact sounds, but also cause the tool to collide with the movable pin. The wear, deformation and damage of the tool ...
