[0019] Embodiment 1: Horizontal installation mechanism

[0020] See also Figure 1 and Figure 2 , the horizontal mounting mechanism comprises a first mounting platform 3, a first groove 4 and a first screw hole 5;

[0021] The first mounting platform 3 is located in the middle of one end above the machine tool 1 and is fixedly connected to the middle of one end above the machine tool 1, and is used to support and position the horizontally mounted spindle 2. A first groove 4 is provided in the middle of the top of the first mounting platform 3, which is used to drain and dissipate the heat generated during the use of the spindle. A plurality of first screw holes 5 are provided on both sides of the upper surface of the first mounting platform 3, which are used to position the mounting nuts. The spindle 2 is horizontally mounted above the first mounting platform 3 through the first screw holes 5.

[0022] It should be noted that during installation, the bottom of the spindle 2 is clamped to the top of the first mounting platform 3, so that the third threaded holes provided on the front and rear sides of the spindle 2 are aligned with the first threaded holes 5, and then the mounting nut is passed through the third threaded hole on the spindle 2 and clamped into the first threaded hole 5 on the first mounting platform 3, so that the spindle 2 is installed on the first mounting platform 3, completing the horizontal installation process;
