[0024] like Figure 1-5 As shown, a CNC lathe for facilitating hydraulic clamping of a workpiece comprises a CNC lathe shell 1, a processing head 2 is penetrated at the top of the CNC lathe shell 1, a nozzle 3 is fixedly connected to the processing head 2, a base 4 is fixedly connected to the bottom of the inner wall of the CNC lathe shell 1, a groove 14 is opened at the top of the base 4, a plurality of first slide grooves 7 are opened at the bottom of the groove 14, square grooves 9 are opened at both ends of the groove 14, second slide grooves 8 are opened at the upper and lower ends of the square groove 9, a moving plate 5 is arranged on both sides of the groove 14, a plurality of second rolling grooves 17 are opened at the bottom of the moving plate 5, and a first rolling ball 6 is arranged on the inner wall of the second rolling groove 17, the first rolling ball 6 is evenly arranged on the moving plate 5, and the moving plate 5 is stably placed in the groove 14 by the first rolling ball 6 to prevent the moving plate 5 from shaking when moving;

[0025] The two ends of the moving plate 5 are fixedly connected with moving columns 10, and the upper and lower ends of the moving column 10 are provided with a plurality of first rolling grooves 15, and the inner wall of the first rolling groove 15 is provided with second balls 16, and the second balls 16 are also evenly arranged on the moving column 10. The moving column 10 is stuck in the square groove 9 by the second balls 16, so that the moving column 10 does not shake when moving, thereby further ensuring the stability of the moving plate 5, and a hydraulic rod 23 is fixedly connected between the moving plates 5;

[0026] When in use, the hydraulic rod 23 is first started to move the movable plate 5. During the movement, the second ball 16 rolls in the second slide groove 8 and the first ball 6 rolls in the first slide groove 7. Therefore, the friction during movement can be reduced, the wear is reduced, and the service life of the hydraulic clamping mechanism is increased.

[0027] In this embodiment, telescopic grooves 22 are provided at both ends of the movable plate 5, a spring 21 is fixedly connected to one end of the inner side of the telescopic groove 22, a clamping column 19 is fixedly connected to one end of the outer side of the spring 21, a through hole 20 is penetrated at the top of the telescopic groove 22, a push plate 12 is provided on the inner wall of the through hole 20, and the bottom end of the push plate 12 is fixedly connected to the top of the clamping column 19, a clamp 11 is provided on the outer wall of the movable plate 5, and clamping grooves 18 are provided on both sides of the inner wall of the clamp 11, and the inner wall of the clamping groove 18 is provided on the outer wall of the clamping column 19;

[0028] By pushing the push plate 12 inward, the column 19 is moved inward, so that the column 19 leaves the range of the slot 18 and shrinks into the telescopic slot 22. At this time, a new clamp 11 is replaced and installed on the movable plate 5. At this time, the push plate 12 is released and the column 19 is clamped into the slot 18 through the reset action of the spring 21, thereby completing the limit fixation of the clamp 11. Therefore, it can be replaced according to the shape of the workpiece, thereby facilitating the hydraulic clamping of workpieces of different shapes.

[0029] In this embodiment, both ends of the movable plate 5 are fixedly connected with stoppers 13, the top of the stoppers 13 are arranged at the bottom of the clamp 11, and the clamp 11 is positioned and installed by the stoppers 13 to prevent misalignment during the installation process.

[0030] In this embodiment, the outer wall of the first ball 6 is arranged on the inner wall of the first slide groove 7, and the outer wall of the second ball 16 is arranged on the inner wall of the second slide groove 8. When moving, the first ball 6 moves in the first slide groove 7 and the second ball 16 moves in the second slide groove 8.

[0031] In this embodiment, the width of the moving plate 5 is smaller than the width of the groove 14, and the thickness of the moving column 10 is smaller than the thickness of the square groove 9, which prevents the moving plate 5 from contacting the groove 14 and the moving column 10 from contacting the square groove 9, thereby avoiding friction.

[0032] It should be noted that the utility model is a CNC lathe that facilitates hydraulic clamping of a workpiece. When in use, the hydraulic rod 23 is first started to move the movable plate 5, and during the movement, the second ball 16 rolls in the second slide groove 8 and the first ball 6 rolls in the first slide groove 7, so that the friction during movement can be reduced, the wear is reduced, and the service life of the hydraulic clamping mechanism is increased;

[0033] When in use, the push plate 12 is pushed inward to move the column 19 inward, so that the column 19 leaves the range of the slot 18 and shrinks into the telescopic slot 22. At this time, a new clamp 11 is replaced and installed on the movable plate 5. At this time, the push plate 12 is released and the column 19 is clamped into the slot 18 through the reset action of the spring 21, thereby completing the limit fixation of the clamp 11. Therefore, it can be replaced according to the shape of the workpiece, thereby facilitating the hydraulic clamping of workpieces of different shapes.
