[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] The utility model embodiment discloses an adjustable CNC lathe clamp.

[0024] The utility model provides Figure 1-Figure 4The adjustable CNC lathe fixture shown in the figure includes a machine body 1, an arc-shaped support seat 5, an arc-shaped slide rail 6 and an arc-shaped sliding seat 9. The top end of the machine body 1 is slidably connected to a movable mold 2, and the other top end of the machine body 1 is fixedly connected to a fixed mold 3. The side wall of the movable mold 2 is fixedly connected to a mounting base 4, and the side wall of the mounting base 4 is fixedly connected to the arc-shaped support seat 5 by a lifting mechanism. Both ends of the arc-shaped support seat 5 are fixedly connected to the arc-shaped slide rail 6, and the side walls of the arc-shaped slide rails 6 at both ends are slidably connected to slide rods 7 by sliding openings. One end of the slide rods 7 at both ends passes through the sliding openings opened on the side walls of the arc-shaped slide rail 6, and are fixedly connected to arc-shaped limit blocks 8. The other ends of the slide rods 7 at both ends are fixedly connected to the arc-shaped sliding seat 9. The side wall of the arc-shaped sliding seat 9 is rotatably connected to the arc-shaped support seat 5 by a driving mechanism. The other side wall of the arc-shaped sliding seat 9 is fixedly connected to a fixed table 10. The cavity of the fixed table 10 The inner rotation is connected with a bidirectional screw 11, and the rod walls at both ends of the bidirectional screw 11 are threadedly connected with a first threaded seat 12. The side walls of the first threaded seats 12 at both ends pass through the sliding openings opened on the side walls of the fixed platform 10, and are fixedly connected with clamps 13. The set lifting mechanism is used to facilitate the height adjustment of the clamp. The sliding rod 7 and the arc limit block 8 set at the sliding opening of the arc slide rail 6 are used to limit the arc sliding seat 9 to the left and right during the rotation of the arc support seat 5 through the driving mechanism, so that the arc sliding seat 9 drives the clamp at one end to adjust the angle. The set bidirectional screw 11 is used to drive the first threaded seats 12 at both ends to move during the rotation process, so that the clamps 13 on the side walls of the first threaded seats 12 at both ends clamp and fix the workpiece, thereby solving the problem of frequent manual replacement of different clamps for processing products with different requirements.

[0025] To adjust the height of the fixture, Figure 1 and 2 As shown, the lifting mechanism includes a connecting bin 14, a one-way screw 15, a first motor 16 and a second threaded seat 17. One side of the connecting bin 14 is fixedly connected to the side wall of the mounting base 4. The one-way screw 15 is rotatably connected in the cavity of the connecting bin 14. The first motor 16 is fixedly connected in the top cavity of the connecting bin 14. One end of the one-way screw 15 is fixedly connected to the main shaft of the first motor 16. The rod wall of the one-way screw 15 is threadedly connected to the second threaded seat 17. One end of the second threaded seat 17 passes through a sliding opening provided on the side wall of the connecting bin 14 and is fixedly connected to one side of the arc-shaped support seat 5. The one-way screw 15 rotatably connected in the cavity of the connecting bin 14 is driven to rotate by the first motor 16, so that the second threaded seat 17 on the rod wall of the one-way screw 15 moves, thereby driving the clamp on the side wall of the second threaded seat 17 connected through the support seat 5 and the arc-shaped sliding seat 9 to adjust the height.

[0026] In order to make the arc-shaped sliding seat 9 rotate on the side wall of the arc-shaped support seat 5 through the cooperation of the arc-shaped slide rail 6, the slide rod 7 and the arc-shaped limit block 8, as shown in FIG. Figure 2 and 3 As shown, the driving mechanism includes an arc-shaped worm wheel 18, a bracket 19, a worm 20 and a second motor 21. The side wall of the arc-shaped support seat 5 is fixedly connected with the arc-shaped worm wheel 18, one end of the side wall of the arc-shaped sliding seat 9 is fixedly connected with the bracket 19, the worm 20 is rotatably connected between the brackets 19, and the other end of the side wall of the arc-shaped sliding seat 9 is fixedly connected with the second motor 21. The main shaft of the second motor 21 is fixedly connected to one end of the worm 20, and the rod wall of the worm 20 is meshed with the teeth of the arc-shaped worm wheel 18. The worm 20 arranged on the side wall of the arc-shaped sliding seat 9 is meshed and rotated with the arc-shaped worm wheel 18 on the side wall of the arc-shaped support seat 5, so that the sliding rod 7 and the arc-shaped limit block 8 on the side wall of the arc-shaped sliding seat 9 are rotated on the side wall of the arc-shaped support seat 5 under sliding cooperation on the arc-shaped slide rail 6, so that the angle adjustment of the clamp of the side wall of the arc-shaped sliding seat 9 can be achieved.

[0027] In order to facilitate the stable clamping of workpieces of different shapes, such as Figure 4 As shown, the side walls of the clamping plates 13 at both ends are provided with arc grooves and rubber layers, and the side walls of the clamping plates 13 at both ends are provided with arc grooves and rubber layers, so as to facilitate the stable clamping of workpieces of different shapes.

[0028] In order to facilitate the operation of the bidirectional screw 11 to rotate, Figure 1 and 4 As shown, one end of the bidirectional screw 11 passes through the opening on the top of the fixed platform 10 and is fixedly connected with a rotating handle 22. The rotating handle 22 set at one end of the bidirectional screw 11 is used to facilitate the operation of the bidirectional screw 11 for rotation.

[0029] Finally, in order to prevent the arc-shaped sliding seat 9 from falling off the track during the rotation of the side wall of the arc-shaped supporting seat 5, Figure 1 As shown, the side walls of the arc-shaped sliding seats 9 at both ends are fixedly connected with arc-shaped positioning plates 23, and the arc-shaped positioning plates 23 at both ends are slidably connected to the side walls of the arc-shaped slide rails 6 at both ends.

[0030] Working principle:

[0031] When in use, the rotating handle 22 is manually rotated to drive the bidirectional screw 11 to rotate, so that the first threaded seat 12 at both ends of the bidirectional screw 11 drives the clamping plate 13 to move, and the workpiece is placed between the clamping plates 13 at both ends, and is fixed by clamping the clamping plates 13, and is adjusted to a suitable height by the provided lifting mechanism, and the worm 20 provided on the side wall of the arc-shaped sliding seat 9 is meshed and rotated with the arc-shaped worm wheel 18 on the side wall of the arc-shaped support seat 5, so that the arc-shaped sliding seat 9 cooperates with the arc-shaped slide rails 6 at both ends of the arc-shaped support seat 5 through the slide rod 7 and the arc-shaped limit block 8, and rotates on the side wall of the arc-shaped support seat 5, so that the angle of the fixture of the side wall of the arc-shaped sliding seat 9 is adjusted, and the arc-shaped positioning plate 23 provided on the side wall of the arc-shaped sliding seat 9 at both ends is connected with the side wall of the arc-shaped slide rails 6 at both ends during the rotation process, so as to prevent the arc-shaped sliding seat 9 from moving left and right during the rotation process of the side wall of the arc-shaped slide rails 6 at both ends, thereby solving the problem of frequent manual replacement of different fixtures for processing when facing products with different requirements.
