It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0021] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0022] Embodiment 1, as Figures 1 - 4 shown, the present utility model provides a high-stability numerical control machine tool support device, including: a plurality of support legs 1, four bolts 4 and four insert rods 5. A bearing plate 2 is fixedly connected between the upper end surfaces of the plurality of support legs 1; a support assembly 3, the support assembly 3 is fixedly connected to the top of the bearing plate 2, the support assembly 3 includes a support frame 301, a placing groove 304 is opened at the top of the support frame 301, force measuring plates 305 are symmetrically and fixedly connected to the inner bottom of the placing groove 304, the inner surface of the support frame 301 is rotatably connected to a driving shaft 309, a connecting plate 311 is fixedly connected to the outer surface of the driving shaft 309, a plurality of extension rods 312 are fixedly connected to the outer surfaces on both sides of the connecting plate 311, pressing blocks 313 are fixedly connected between the end surfaces of the two groups of extension rods 312, slots 302 are opened at the corners of the top of the support frame 301, jacks 303 are symmetrically opened on the outer surfaces on both sides of the support frame 301, the jacks 303 are communicated with the slots 302, the outer surface of the insert rod 5 is inserted into the inner surface of the slot 302, a top plate 6 is fixedly connected between the upper end surfaces of every two insert rods 5, a card slot 7 is opened at the bottom of the top plate 6, a motor 306 is fixedly connected to the outer surface of the support frame 301, the output end of the motor 306 penetrates through the support frame 301 and extends to the inside, the output end of the motor 306 is fixedly connected to a rotating shaft 307, a first gear 308 is fixedly connected to the end surface of the rotating shaft 307, a second gear 310 is fixedly connected to the outer surface of the driving shaft 309, and the first gear 308 is meshed with the second gear 310.

[0023] The effect achieved by the entire Embodiment 1 is that when using the support device to support and fix the machine tool, place the machine tool at the inner position of the placement groove 304, and then drive the insertion rods 5 on both sides of the top plate 6 into the insertion slots 302. At this time, the top plate 6 is above the machine tool. Through the setting of the clamping slots 7, the machine tool is positioned between the top plate 6 and the support frame 301. Then insert the bolt 4 into the insertion hole 303 and turn it. After the bolt 4 is screwed into the threaded hole, the installation and fixation of the machine tool are completed. At this time, the bearing plate 2 at the bottom of the support frame 301 and the support feet 1 provide stable support for the machine tool. During the use process after the machine tool is placed stably, both sides of the bottom of the machine tool will respectively press on the upper positions of the two force measuring plates 305. Through the use of the force measuring plates 305, the pressure data exerted by the machine tool on them can be measured respectively. If the weights of the items placed on the surface of the machine tool are uneven during use, the pressure data of the two force measuring plates 305 will deviate. In order to prevent the support device from being unevenly stressed and affecting stability when the machine tool is unevenly pressured, the bearing states of the bearing plate 2 and the support feet 1 are adjusted by the operation of the motor 306. After the motor 306 operates, it can drive the rotating shaft 307 to rotate accordingly. Through the rotation of the rotating shaft 307, the first gear 308 can be driven to rotate. The first gear 308 can drive the drive shaft 309 to rotate through meshing with the second gear 310. Through the rotation of the drive shaft 309, the connecting plate 311, the extension rod 312, and the pressing block 313 are driven to rotate. After the drive shaft 309 rotates, the pressing blocks 313 on both sides will be in a state of one high and one low. At this time, by controlling the motor 306, the pressing block 313 on the side where the machine platform bears greater pressure is in the high position, and the pressing block 313 on the other side is in the lower position. As the motor 306 operates to drive the drive shaft 309 to rotate, the axial force of the drive shaft 309 can be converted into up and down pressure by the pressing block 313, so that the side of the machine platform under pressure receives an upward thrust, while the pressing block 313 on the other side exerts a downward pressure on the support frame 301. That is, by using the pressing blocks 313 on both sides, the pressures borne by both sides of the support frame 301 are leveled, ensuring that the bearing plate 2 and the support feet 1 always bear relatively uniform pressures, effectively improving the stability of the support device.

[0024] Embodiment 2 is as Figures 1 - 4 shown. Threaded holes are provided on the outer surface of the insertion rod 5, and the threaded holes are in cooperation with the positions of the insertion holes 303. The outer surface of the bolt 4 is threadedly connected to the inner surface of the threaded hole.

[0025] The effect achieved by the entire Embodiment 2 is that through the setting of clamping and fixing the machine platform with the support device by the top plate 6 being above the machine platform, compared with the bottom clamping method, the stress area for clamping the machine platform is larger, improving the stability of the position of the machine platform.

[0026] Working principle: When using the support device to support and fix the machine tool, place the machine tool inside the placement groove 304. Then, drive the insertion rods 5 on both sides of the top plate 6 into the insertion slots 302. At this time, the top plate 6 is above the machine tool. Through the setting of the clamping slots 7, the machine tool is positioned between the top plate 6 and the support frame 301. Then, insert the bolts 4 into the insertion holes 303 and turn them. After the bolts 4 are screwed into the threaded holes, the installation and fixation of the machine tool are completed. At this time, the bearing plate 2 at the bottom of the support frame 301 and the support feet 1 provide stable support for the machine tool. During the use process after the machine tool is placed stably, both sides of the bottom of the machine tool will respectively press on the upper positions of the two force measuring plates 305. By using the force measuring plates 305, the pressure data exerted by the machine tool on them can be measured respectively. If the weights of the items placed on the surface of the machine tool are uneven during use, the pressure data of the two force measuring plates 305 will deviate. To prevent the support device from being unevenly stressed and affecting stability when the machine tool is unevenly pressured, the bearing states of the bearing plate 2 and the support feet 1 are adjusted by the operation of the motor 306. After the motor 306 operates, it can drive the rotating shaft 307 to rotate. Through the rotation of the rotating shaft 307, the first gear 308 can be driven to rotate. The first gear 308 can drive the drive shaft 309 to rotate through meshing with the second gear 310. Through the rotation of the drive shaft 309, the connecting plate 311, the extension rod 312, and the pressing block 313 are driven to rotate. After the drive shaft 309 rotates, the two pressing blocks 313 on both sides will be in a state of one high and one low. At this time, by controlling the motor 306, the pressing block 313 on the side where the machine platform bears greater pressure is in the high position, and the pressing block 313 on the other side is in the lower position. As the motor 306 operates to drive the drive shaft 309 to rotate, the axial force of the drive shaft 309 can be converted into up and down pressure by the pressing block 313, so that the side of the machine platform bearing pressure receives an upward thrust, while the pressing block 313 on the other side exerts a downward pressure on the support frame 301. That is, by using the two pressing blocks 313 on both sides, the pressures borne by both sides of the support frame 301 are leveled, ensuring that the bearing plate 2 and the support feet 1 always bear relatively uniform pressures, effectively improving the stability of the support device. Through the setting of clamping and fixing the machine platform with the top plate 6 above the machine platform, compared with the bottom clamping method, the stress area of the machine platform clamping is larger, improving the stability of the machine platform position.

[0027] The above is only a preferred embodiment of the present invention, and it does not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
