[0023] Please refer to Figure 1 and Figure 3 as well as Figure 4 , the present invention provides a double-spindle fixed sliding base, which includes two support frames 4. A mounting plate 11 is fixedly connected between the bottoms of the two support frames 4. On the opposite sides of the tops of the two support frames 4, a support plate 9 is installed. The top of the support frame 4 is fixedly connected with a slide block 3. A slideway 7 is opened at the top of the slide block 3, and a main shaft cross beam 14 is slidably sleeved outside the slideway 7.

[0024] Please refer to Figure 1 and Figure 3 , a screw rod placement groove 10 is opened at the center of the support plate 9. A motor mounting bracket 2 is fixedly installed on one side of the support plate 9 close to the screw rod placement groove 10. The outside of the motor mounting bracket 2 is in a rectangular structure. A bearing seat 8 is installed outside the support plate 9, and the bearing seat 8 is located outside the support plate 9.

[0025] Please refer to Figure 1 and Figure 2 , the inside of the support frame 4 is in a hollow structure. A support bar 15 is fixedly connected to the inner side of the support frame 4. A vertical plate 12 is fixedly connected to the center of the inside of the support frame 4, and the vertical plate 12 is perpendicular to the support bar 15. The main functions of the vertical plate 12 and the support bar 15 inside the support frame 4 are to improve tightness and stability, provide lateral support points for the overall stability of the vertical plate 12, the support bar 15 and the support frame 4, and facilitate the support of the structure.

[0026] Please refer to Figure 1 and Figure 2 , the inside of the slide block 3 is in a central structure. A fixed frame 16 is installed inside the slide block 3, and a plurality of support blocks 13 are arranged in an array on the fixed frame 16. By adding the structure of the fixed frame 16 and the support blocks 13 inside the slide block 3, the fixed frame 16 and the support blocks 13 are prevented from deforming or cracking when stressed, and the load-bearing capacity of the entire structure is improved.

[0027] Please refer to Figure 1, limiting grooves 6 are provided on the outsides of both the mounting plate 11 and the support frame 4, and mounting holes 5 are provided inside the limiting grooves 6. The mounting holes 5 provided in the limiting grooves 6 are mainly used to fix and restrict the movement of the mounting plate 11 and the support frame 4, ensuring stability and accuracy during the processing, and ensuring that there will be no movement or deviation during the processing.

[0028] Please refer to Figure 1 and Figure 3 , lightweight holes 17 and lightweight holes 1 are respectively provided on the outsides of the support frame 4 and the support plate 9. For the operator, the support frame 4 and the support plate 9 with lightweight holes 17 and lightweight holes 1 also mean more convenient and faster handling, installation and maintenance, reducing labor costs. In addition, for mechanical equipment that needs to be frequently moved or adjusted in position, the lightweight design helps to improve its mobility and flexibility, and also has sufficient strength to meet the strength requirements of the mechanical structure.

[0029] Please refer to Figure 1 , a bearing groove 18 is provided inside the bearing seat 8. The bearing groove 18 in the bearing seat 8 ensures that it can accurately undertake the work of supporting and rotating, guarantees the position accuracy of the bearing, and also enables the bearing seat 8 to remain stable when bearing the load, avoiding mechanical failures caused by loosening or displacement.

[0030] Please refer to Figure 1 , the support frame 4 and the slider 3 are fixedly connected by welding. Welding connection does not require drilling holes in the steel, which not only saves working time but also avoids the reduction of the cross-sectional area of the material due to drilling, thus making full use of the material. The structure of the welding connection is simple, easy to manufacture, has a large connection stiffness and good sealing performance, increasing the connection strength between the support frame 4 and the slider 3.

[0031] Working principle:

[0032] Install an external motor inside the motor mounting bracket 2 such that one side of the output shaft of the motor mounting bracket 2 is located on one side of the bearing block 8. Then, install one end of the external lead screw outside the motor mounting bracket 2 such that the outside of the lead screw is located outside the lead screw placement groove 10 and the end is located inside the bearing groove 18. The main shaft cross beam 14 is slidably connected to the upper surface of this base and moves back and forth driven by the lead screw in the motor, causing the main shaft cross beam 14 to slide through the slideway 7 on the slider 3. The connection by welding does not require drilling holes in the steel, which not only saves working time but also avoids the reduction of the cross-sectional area of the material due to drilling, thus making full use of the material. The welded connection has a simple structure, is easy to manufacture, has a large connection stiffness, and good sealing performance. It increases the connection strength between the support frame 4 and the slider 3. At the same time, lightweight holes 17 and 1 are respectively provided on the outer parts of the support frame 4 and the support plate 9. For the operator, the support frame 4 and the support plate 9 with lightweight holes 17 and 1 also mean more convenient and faster handling, installation, and maintenance, reducing the labor cost. In addition, for mechanical equipment that needs to be frequently moved or adjusted in position, the lightweight design helps improve its mobility and flexibility and also has sufficient strength to meet the strength requirements of the mechanical structure.
