Description

Closed-locking position device for rotating shaft of processing spindle

This creation particularly refers to the provision of a closed locking device that can effectively close the locked rotary shaft so that the machining spindle can ensure the machining accuracy.

According to the press, the processing spindle is installed on the processing tool, and when the rotary shaft is sleeved with the processing tool, the rotary tool can be used to rotate the processing tool at high speed to perform the rotary milling operation on the processed part. In addition, when the rotation axis of the processing spindle does not rotate, turning can be performed if the workpiece is converted. If the rotation axis of the processing spindle and the workpiece are not rotated, the processing spindle can be used to drive the processing spindle or workpiece It can move linearly and perform cutting work. Generally speaking, the machining spindle is mainly used to perform rotary milling on the workpiece. However, when turning or cutting is to be performed, the rotation axis of the machining spindle must be non-rotating. Therefore, the rotation axis must be closed and locked. . The conventional method of closing and locking the rotating shaft is mainly based on a rotating disk connected to the upper end of the rotating shaft, and a braking device is correspondingly mounted on the seat of the processing spindle, and the rotating disk is clamped by the braking device, so that The rotation axis is positioned; however, the closed position method has the following disadvantages:

1. Since the lower end of the rotary shaft is socketed with a machining tool, the lower end of the rotary shaft is the most stressed part when the machining operation is performed for the entire rotary shaft. However, the rotary disk and the braking device are installed at the upper end of the rotary shaft. In this case, twisting is likely to occur, and the rotary shaft cannot be reliably closed, thereby affecting machining accuracy.

2. When turning is performed, the machining tool and the rotating shaft are subject to large forces. Therefore, the positioning method of the rotating disk and the brake device will not be able to reliably close the locked position due to insufficient rigidity and stability, which will affect the processing. Precision.

In view of this, the creator then used his years of research and development and production experience in related industries to in-depth research on the current problems. After long-term research and trial work, he finally developed a closed-lock device for processing the rotation axis of the main shaft. In order to effectively improve the shortcomings of knowledge, this is the design purpose of this creation.

The first purpose of this creation is to provide a closed-locking position device for the rotary shaft of a processing spindle. A first stopper gear is installed near the lower end of the rotary shaft, and the seat body is outside the first stopper gear. A second stopper sprocket is installed, and the seat body is provided with a fluid-driven lockout sprocket at a position opposite to the disc surface of the first stopper sprocket and the second stopper sprocket; thereby, the fluid is used to drive Locking the sprocket can make the locking sprocket mesh with the first and second stopper sprockets at the same time, and the rotary shaft is locked at the lower end to effectively reduce the phenomenon of twisting, and then the lock position is rotated. Shaft to achieve the benefits of ensuring machining accuracy.

The second purpose of this creation is to provide a closed-locking position device for processing a rotating shaft of a main shaft, wherein the locking toothed disc can simultaneously engage with the first and second stopper toothed discs, and is a three-piece type. The toothed coupling is closed and locked, which can effectively improve the rigidity and stability of the meshing, and then close the rotating shaft in the locked position to achieve the benefit of ensuring machining accuracy.
