Non-contact limit switch machine tool spindle orientation parking device and parking method

Abstract

The invention relates to a contactless travel switch machine tool spindle directional parking device and a parking method of the contactless travel switch machine tool spindle directional parking device. The contactless travel switch machine tool spindle directional parking device comprises a parking trigger assembly and a control circuit. The parking trigger assembly comprises a disc synchronously connected with a machine tool spindle and a sector board fixed to one side of a machine tool spindle box. The face of the disc is provided with two armature pieces which are not located on the same circle. The board face of the sector board is provided with two contactless travel switches sensing the armature pieces when the disc rotates. The parking method includes the steps that when forward rotation of a spindle motor is stopped, one contactless travel switch triggers the corresponding armature piece, and the control circuit controls the spindle motor to rotate reversely at a low speed; in the reverse rotation process of the spindle motor, the other contactless travel switch triggers the corresponding armature piece, the control circuit controls the spindle motor to conduct dynamic braking operation, and the braking function is achieved. The device is simple in structure and control mode, the problem that directional parking of an existing machine tool spindle is inconvenient is effectively solved, and the device is suitable for various machine tool spindles.

Description

technical field

[0001] The invention relates to a machine tool, in particular to a non-contact stroke switch machine tool spindle orientation parking device and a parking method thereof. Background technique

[0002] The machine tool spindle is the axis used to drive the workpiece or tool to rotate on the machine tool. When using a machine tool, it is usually required that the machine tool spindle can stop quickly after the machining process is completed, especially in mass production, it is also required that the starting position and the stopping position are as uniform as possible. However, the existing machine tool spindles often rely on hydraulic, pneumatic or braking technologies when they stop. Although these technologies can realize the rapid stop of the spindle, they do not strictly consider the inertial rotation of the spindle when braking, so there are still machine tool spindles. It is difficult to unify the tool position and stop position. For this reason, suc...

[0016] Now in conjunction with accompanying drawing, the present invention will be further described.

[0017] like Figure 1~3 As shown, the non-contact travel switch machine tool spindle directional parking device is installed on one side of the spindle box 1, and the end of the spindle 2 protruding from the side of the spindle box is fixedly connected to the disc 3, and the disc and the spindle rotate synchronously. This side of the spindle box is connected with the sector plate 5 by bolt 7, the sector plate is parallel to the disc, the sector plate inner side is opposite to the disc outer surface, and the respective centers of the sector plate and the disc are positioned on the axis line of the main shaft. The disk surface of the disc is provided with two groups of screw holes 301 arranged around the circumference and connected to the armature piece 4. The radius of the circumference of the two groups of screw holes is different. One of the screw holes of one group of scre...
