[0030] Embodiment, a clamping device for flute processing, such as Figure 1 , Figure 2 As shown, it includes a workbench 1 with parallel grooves 14 and 15, a bidirectional screw rod 2 rotatably connected in the groove 14 and with opposite thread directions at both ends, a slide bar 3 fixed in the groove 2 15, a support plate 13 welded on the moving plate 4, a bidirectional motor 12 that drives the bidirectional screw rod 2 to rotate and is fixed on the support plate 13, a moving plate 4 that is threadedly connected at both ends of the bidirectional screw rod 2 and slidably connected to the slide bar 3, a support ring 5 welded on the top of the moving plate 4 and rotatably connected to a turntable 6, and a support ring 5 inserted into the support ring 5 and screwed at the bottom. Two bolts 7 symmetrically arranged on the support ring 5 are connected to the threaded holes 62 of the turntable 6, wherein one side of the turntable 6 is evenly provided with three slide grooves 61 along the diameter and passing through the center of the circle, and the other side is provided with a clamping assembly 10 for clamping the workpiece, including a bidirectional screw 101, a guide rod 102, a sliding block 103, a clamping plate 104, and a micro motor 105. The bidirectional screw 101 and the fixing rod are connected to the turntable 6 through a base 11, and a three-claw crank 9 is slidably connected to the slide groove 61, and a driving motor 8 is driven to rotate the three-claw crank 9.

[0031] Its working principle is as follows: first, the distance between the two clamping assemblies 10 is adjusted according to the length of the flute tube workpiece, and the bidirectional motor 12 is started to drive the bidirectional screw 2 to rotate, thereby driving the two moving plates 4 to move closer to or away from each other along the slide rod 3, and the support ring 5 and the turntable 6 on the moving plate 4 move closer to or away from each other to achieve the adjustment of the distance between the clamping assemblies 10. After the adjustment is completed, the two ends of the workpiece are placed between the clamping plates 104, and the micro motor 105 is started to drive the bidirectional screw 101 to rotate, thereby driving the sliding block 103 to slide along the guide rod 102, so that the two sliding blocks 103 are close to each other. Thus, the clamping plate 104 clamps one end of the workpiece, and repeats the operation at the other end to clamp the workpiece between the two turntables 6 to fix it. When grinding, start the drive motor 8 to drive the three-claw crank 9 to rotate in the slide groove 61, and the turntable 6 drives the clamping assembly 10 to clamp the flute tube and rotate for grinding. When drilling, insert the bolt 7 into the support ring 5 and tighten the bolt 7, fix the turntable 6 and the support ring 5 together to limit the rotation of the turntable 6, and then the drilling work can be carried out. After the processing is completed, start the micro motor 105 in the reverse direction to drive the bidirectional screw 101 to loosen the workpiece.

[0032] Specifically, an anti-wear layer is provided on the inner side of the clamping plate 104 to prevent the surface of the workpiece from being worn.
