[0023] The cutting fluid will flow to the bed along with the machining debris, and under the guidance of the drainage groove, it will flow into the chip removal device by its own gravity for filtration and recycling. In the related art, the drainage groove is set as a wide groove with a very wide bottom wall to prevent the machining debris from blocking, but the contact area between the machining debris and the groove wall of the drainage groove is increased, the friction force is increased, and the chip removal efficiency still cannot meet the production needs.
[0024] For this purpose, refer to Figure 1 and Figure 2 , which is a drainage structure of a machine tool bed proposed by the utility model, includes a bed body 100 that is integrally cast and is a hollow structure. A peripheral edge 101 is provided on the periphery of the top of the bed body 100 to form a groove-like structure. The bed body 100 is provided with a footrest position 110, a guide rail pillow position 120 and a screw seat pillow position 130, which are respectively used to position and install the column, the workbench and the screw seat. A chip groove 300 is provided between the footrest position 110 and the guide rail pillow position 120. A drainage groove 200 is penetrated and connected to one side of the chip groove 300, and a drainage port 400 is connected to the other end. The drainage groove 200 is inclined downward from the chip groove 300 toward the drainage port 400. A first inclined side wall 220 and a second inclined side wall 230 are respectively provided on both sides of the drainage groove 200 along the length direction. The first inclined side wall 220 is inclined downward from the peripheral edge 101 toward the bottom wall 210, and the second inclined side wall 230 is inclined downward from the side wall of the guide rail pillow position 120 toward the bottom. It can be understood that the bed body 100 with a groove-shaped structure is used to position and install components such as workbenches and columns. The integral casting into a hollow structure is conducive to weight reduction, cost reduction, and convenient transportation, and is also conducive to open chip removal and drainage. The chip removal groove 300 arranged between the footrest position 110 and the guide rail sleeper position 120 is located below the main shaft of the machine tool, and can receive more processing debris, which are discharged into the drainage groove 200 along with the cutting fluid. The drainage groove 200 is arranged as a whole to discharge the cutting fluid and the processing debris by gravity. The bottom of the drainage groove 200 gradually decreases, and the cross-sectional opening width of the drainage groove 200 gradually decreases. The first inclined side wall 220 and the second inclined side wall 230 located on both sides cooperate to guide the cutting fluid and reinforce the debris to gather into a ball as much as possible, reduce the contact area with the surface of the bed body 100, and reduce the friction. At the same time, the gravity work of the agglomerated debris increases, and it can be more effectively discharged to the drainage port 400 automatically, and finally the cutting fluid is filtered out for recycling. The width of the bottom wall 210 is narrowed, the inclination is increased, and the gravity of the processing debris is amplified, thereby preventing blockage, improving chip removal efficiency, and meeting production needs. Furthermore, the width of the bottom wall 210 gradually decreases from the chip groove 300 to the drain port 400 to improve the effect of gathering the debris.
[0025] Reference Figure 2Optionally, in some embodiments, the inclination angle of the first inclined side wall 220 is smaller than the inclination angle of the second inclined side wall 230, thereby increasing the width of the first inclined side wall 220 near the surrounding edge 101, thereby preventing debris from flying out of the bed body 100 during chip removal and preventing additional cleaning work burden.
[0026] Reference Figure 2 The inclination angle of the first inclined side wall 220 is 30° to 45°, and the inclination angle of the second inclined side wall 230 is 60° to 75°.
[0027] In some embodiments, the first inclined side wall 220 is connected to the second inclined side wall 230 , and the cross section of the drainage groove 200 is a “V” shape, which further reduces the contact area between the debris and the bed body 100 and ensures the chip removal efficiency.
[0028] Reference Figure 1 In some embodiments, a guide slant wall 401 is provided at the connection between the drain outlet 400 and the drain groove 200 , and the guide slant wall 401 slopes downward from the drain groove 200 toward the drain outlet 400 to prevent processing debris from being stuck in the connection gap between the drain outlet 400 and the drain groove 200 .
[0029] Reference Figure 3 A plurality of reinforcing ribs 102 are provided in the bed body 100 to ensure the strength and stability of the bed body 100 , and further ensure the machining accuracy of the assembled machine tool.
[0030] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
