The lower ends of the two lead screws 13 are connected to a bracket 19 through bearings, and the bracket 19 is fixedly connected to the U-shaped column 4. A sliding platform 8 is arranged on the bed 1, and a sub-column 7 is fixedly installed on the sliding platform 8. The guide rails are distributed in a U shape, which enhances the sectional moment of inertia of the U-shaped column 4 and effectively resists the deformation caused by cutting force and vibration. The U-shaped layout can simultaneously bear radial cutting force, axial load and overturning moment, and disperse stress through multi-point support to reduce the risk of local deformation; Two guide rail assemblies b9 are connected to the U-shaped guide rail 15, two support rods 10 are fixedly installed on each of the two guide rail assemblies b9, four vertical bars 11 are movably sleeved on the four support rods 10, and the four vertical bars 11 are all fixedly connected to the spindle box 5. Two reinforcing rods 21 are fixedly installed on the two guide rail assemblies b9, two cylinders 22 are fixedly installed on the two guide rail assemblies b9, the rear end of the output shaft of the cylinder 22 is fixedly installed with a cross bar 18, and a square block 20 is fixedly installed on the rear side of the cross bar 18. The two square blocks 20 are both fixedly connected to the rear inner wall of the U-shaped column 4. By the telescopic back and forth of the output shaft of the cylinder 22, the two guide rail assemblies b9 can be driven to move back and forth, so that the four support rods 10 can be driven to move back and forth, and thus the spindle box 5 can be driven to move back and forth, so as to adjust the position of the spindle box 5 back and forth. Each mounting groove on the workbench 3 is movably connected with a T-shaped block 25, and a moving block 33 is fixedly installed on each T-shaped block 25. With the T-shaped block 25 and the moving block 33, when there is too much debris accumulated in the mounting groove on the workbench 3, the user can use the moving block 33 to move the T-shaped block 25 back and forth, so that the internal debris can be cleaned by the forward and backward movement of the T-shaped block 25, thus avoiding the influence on the use caused by the difficult cleaning of the long-term accumulation of debris.

Limit plates 37 are fixedly installed on both the left and right sides of the workbench 3. The sides of the two limit plates 37 close to each other are respectively in contact with the two spherical balls 29. Limit blocks 30 are fixedly installed on the rear sides of the two limit plates 37. The cooperation of the limit plates 37 and the limit blocks 30 can prevent the controllable rod 26 from moving left and right and falling off when moving forward and backward, and at the same time can block the controllable rod 26 from moving backward too far, so as to avoid driving the T-shaped block 25 to move backward too far and causing it to fall off. Two sliding grooves 34 are formed on each moving block 33. A number of groups of small blocks 32 are fixedly installed on the front surface of the workbench 3. A limit strip 31 is fixedly installed on each small block 32. Each limit strip 31 is movably connected to each sliding groove 34. Two support plates 23 are fixedly installed on the front surface of the workbench 3. Two vertical plates 24 are fixedly installed on each of the two support plates 23. When the controllable rod 26 drives each T-shaped block 25 to move forward out of the workbench 3, each sliding groove 34 and each limit strip 31 will be connected. Then, when the control rod 26 is released, due to gravity, the T-shaped block 25 and the control rod 26 will move downward, thus exposing the installation groove on the workbench 3, so as to avoid the installation groove on the workbench being blocked and affecting the installation of the device to be processed.

[0023] During use, the first step: the guide rails are distributed in a U shape, which enhances the sectional moment of inertia of the U-shaped column 4, effectively resists the deformation caused by cutting force and vibration. The U-shaped layout can simultaneously bear the radial cutting force, axial load and overturning moment, and disperses the stress through multi-point support, reducing the risk of local deformation.

[0024] The second step: by the output shaft of the cylinder 22 to retract and extend, the two guide rail assemblies b9 can be driven to move back and forth, so as to drive the four support rods 10 to move back and forth, and then the spindle box 5 can be driven to move back and forth, so as to adjust the position of the spindle box 5 back and forth.

[0025] The third step: through the T-shaped block 25 and the moving block 33, when there is too much debris accumulated in the installation groove on the workbench 3, the user can use the moving block 33 to move the T-shaped block 25 back and forth, so as to clean the internal debris by the forward and backward movement of the T-shaped block 25, thus avoiding the debris being difficult to clean after long-term accumulation and affecting the use.

[0026] The fourth step: by placing the control rod 26 in the L-shaped groove 35 on each short strip 36, each short strip 36 can be driven to move back and forth to clean the debris, so as to facilitate the user to clean the debris in all installation grooves.

[0027] Step 5: By cooperating the limiting plate 37 with the limiting block 30, it can prevent the control rod 26 from moving left and right and falling off when moving forward and backward, and at the same time, it can block the control rod 26 from moving too far backward, so as to avoid driving the T-shaped block 25 to move too far backward and cause it to fall off.

[0028] Step 6: When each T-shaped block 25 is driven forward by the controllable rod 26 to move out of the workbench 3, each chute 34 will be connected to each limiting strip 31. Then, release the control rod 26. Due to gravity, the T-shaped block 25 and the control rod 26 will move downward, thus exposing the installation groove on the workbench 3, so as to avoid the installation groove on the workbench being blocked and affecting the installation of the device to be processed.

[0029] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
