By setting the support wheels 204, the installation plates 203 are supported to ensure the stability when the installation plates 203 move. A vertical plate 206 is fixedly installed at the top of the base 1. A driven shaft 2016 is rotatably connected to one side of the vertical plate 206 close to the bidirectional lead screw 205. A bevel gear one 2019 is fixedly installed at one end of the driven shaft 2016 away from the vertical plate 206. A bevel gear two 2021 is fixedly installed on the outer side of the bidirectional lead screw 205. The bevel gear two 2021 is meshed with the bevel gear one 2019. A support block 2018 is fixedly installed at the top of the base 1 between the vertical plate 206 and the bevel gear one 2019. The driven shaft 2016 passes through the support block 2018 and is rotatably connected to the support block 2018. By setting the support block 2018, the stable rotation of the driven shaft 2016 is ensured. A driven gear 2017 is fixedly installed on the outer side of the driven shaft 2016 between the vertical plate 206 and the support block 2018. A sleeve block one 202 is fixedly sleeved in the middle of the outer side of the U-shaped round rod one 201. The sleeve block one 202 is between the two nuts 207. A rotary cylinder 209 is rotatably connected to one side of the sleeve block one 202 close to the vertical plate 206.

The movable ring 2011 is located between the limit block one 2020 and the limit block two 2022 and is in contact with the limit block one 2020;

[0026] In the working state, first rotate the handwheel 2014 to drive the movable column 2013 to rotate. Since the two guide blocks 2012 are respectively located in the two guide grooves 2010, the rotating cylinder 209 is driven to rotate, and the driving gear 2015 is driven to rotate. Since the driving gear 2015 is meshed with the driven gear 2017, the driven shaft 2016 is driven to rotate. Since the bevel gear one 2019 is meshed with the bevel gear two 2021, the bidirectional lead screw 205 is driven to rotate, and then the two nuts 207 are driven to slide along the U-shaped round rod one 201. At this time, the distance between the two mounting plates 203 is changed. Then, the numerical control machine tool is fixed on the two mounting plates 203, and finally the support for numerical control machine tools of different sizes is completed.

[0027] Specifically, it is given by Figures 4 - 5 The limiting mechanism 3 includes a U-shaped round rod two 301 fixed between the two sleeve blocks two 208. A slide plate 302 is movably sleeved on the outer side of the U-shaped round rod two 301. Positioning holes 303 are equidistantly arranged on the slide plate 302. Positioning rods 304 are fixedly installed on one side of the two nuts 207 close to the slide plate 302. The two positioning rods 304 are respectively inserted into the two corresponding positioning holes 303. Spring 305 is fixedly connected between the two sleeve blocks two 208 and the slide plate 302. The two springs 305 are both sleeved on the outer side of the U-shaped round rod two 301. Two connecting rods 307 are symmetrically and fixedly connected to one side of the slide plate 302 close to the sleeve block one 202. One ends of the two connecting rods 307 far from the slide plate 302 penetrate through the sleeve block one 202 and are fixedly connected to the same mounting ring 306. And the two connecting rods 307 are both movably connected to the sleeve block one 202. The mounting ring 306 is located between the movable ring 2011 and the limiting block two 2022. A ring groove 309 is arranged on one side of the mounting ring 306 far from the sleeve block one 202. A plurality of balls 308 that are all in contact with the movable ring 2011 are installed at equal angles in the ring groove 309. By arranging a plurality of balls 308 in the ring groove 309, the direct contact between the movable ring 2011 and the mounting ring 306 is avoided, thereby reducing the friction force when the movable ring 2011 rotates;

[0028] In the working state, first push the handwheel 2014 to drive the movable column 2013 to move, and drive the movable ring 2011 to move through the two guide blocks 2012. Then push the mounting ring 306 to move, and drive the slide plate 302 to slide along the second U-shaped round rod 301 through the two connecting rods 307. At this time, both springs 305 are stretched until the mounting ring 306 contacts the second limiting block 2022. At this time, the two positioning rods 304 are respectively disengaged from the two corresponding positioning holes 303, so as to release the limit on the two nuts 207. Then rotate the handwheel 2014 to make the two nuts 207 slide, and the distance between the two mounting plates 203 can be adjusted. When the distance between the two mounting plates 203 is adjusted, then release the control of the handwheel 2014. At this time, the two springs 305 reset to drive the slide plate 302 to move, and drive the mounting ring 306 to move through the two connecting rods 307, and at the same time push the movable ring 2011 until the movable ring 2011 fits with the first limiting block 2020. At this time, the two positioning rods 304 are respectively inserted into the two corresponding positioning holes 303 to realize the limit on the two nuts 207. Finally, the two mounting plates 203 are prevented from moving to realize the stable support of the numerical control machine tool.
