[0002] The installation of a machine tool spindle tool change signal sensing switch refers to the installation of a sensing switch between the spindle and the tool of a CNC machine tool to detect tool position or state changes during tool change. The switch senses the movement or position changes of the spindle or tool, and sends a signal to the control system, thereby realizing automatic monitoring and control of the tool change process.

[0003] Currently, as shown in the attached manual Figure 5 and 6 As shown, the fixing bracket of the direct-connected spindle loosening and pulling tool signal sensing switch is installed on the spindle, and the signal sensing switch is fixed to the bracket by thin nuts on both sides of the bracket. The bracket is installed on the spindle in advance, and the spindle is first installed on the spindle box. Then, the loosening and pulling tool signal sensing switch is fixed to the mounting bracket through the opening of the spindle box with thin nuts. Since the opening of the spindle box affects the strength, the opening cannot be too large, resulting in a small installation space and inconvenient operation. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a method for installing a machine tool spindle tool change signal induction switch, which solves the problem that the direct-connected spindle tool change signal induction switch is inconvenient to install and prone to malfunction.

Install the signal sensing switch on the signal sensing switch mounting left bracket and right bracket; S3. Install the signal induction switch mounting left bracket and the signal induction switch mounting right bracket to the pre-processed threaded holes of the spindle box. Do not completely lock the left and right brackets for the induction switch first. Lock the brackets after adjusting the loosening and pulling tool sensing positions. S4. After adjusting the sensing position, use a feeler gauge to check the distance between the left and right signal sensing switches and the spindle signal sensing belt. After fine-tuning to the appropriate distance, tighten the second thin nut to complete the installation.

[0006] Preferably, the signal sensing switch mounting left bracket and the signal sensing switch mounting right bracket both comprise an L-shaped frame, a mounting plate is fixedly connected to the top of the L-shaped frame, an adjustment groove is opened on the surface of the L-shaped frame, and a bracket fixing screw is arranged inside the adjustment groove.
