[0029] Specifically, a driving mechanism is installed on the base 1, and the driving mechanism includes a bidirectional screw 6, a connecting plate 7, and a driving part 8. The bidirectional screw 6 is rotatably installed in the base 1 and driven by the driving part 8. There are two connecting plates 7, which are respectively installed on the two clamping plates 3. The other ends of the two connecting plates 7 are threadedly connected to the two ends of the bidirectional screw 6. The bidirectional screw 6 is driven to rotate by the driving part 8. The bidirectional spiral design of the bidirectional screw 6 enables the two connecting plates 7 to move toward or away from each other, thereby realizing the adjustment of the distance between the two clamping plates 3.

[0030] The driving part 8 can be a motor and its combined structure in the prior art, or can be manually rotated and self-locked;

[0031] The driving mechanism can also be replaced by a combination of a slide rail and a fastener, the clamping plate 3 is slidably arranged on the slide rail, and the clamping plate 3 is limited and fixed by the fastener to achieve clamping, and can also be adjusted by means of cylinder pushing or the like;

[0032] Furthermore, if Figure 3 As shown, a slide groove adapted to the connecting plate 7 is provided on the top of the base 1, and the slide groove is parallel to the placement plate 2. The end of the connecting plate 7 away from the bidirectional lead screw 6 slides through the slide groove and is fixedly connected to the bottom of the clamping plate 3, so that the clamping plate 3 can be slidably adjusted along the length direction of the placement plate 2;

[0033] Furthermore, if Figure 2As shown, a stabilizing rod 9 parallel to the bidirectional lead screw 6 is installed inside the base 1, and a movable hole 13 adapted to the stabilizing rod 9 is opened on the connecting plate 7. The connecting plate 7 is slidably connected with the stabilizing rod 9 through the movable hole 13. When the bidirectional lead screw 6 rotates to drive the connecting plate 7 to move, the connecting plate 7 can slide on the stabilizing rod 9, which is conducive to improving the movement stability of the connecting plate 7, thereby improving the movement stability of the clamping plate 3. To a certain extent, it can also improve the strength of the connecting plate 7, thereby improving the clamping stability of the clamping plate 3;

[0034] Furthermore, if Figure 3 As shown, the driving mechanism further includes a slider 11, which is threadedly mounted on the bidirectional lead screw 6, and both ends of the slider 11 are fixedly connected to adjacent connecting plates 7 respectively;

The two connecting plates 7 in each group are symmetrically installed at the bottom of the clamping plate 3. When the two sliders 11 are driven to move toward or away from each other by the bidirectional lead screw 6, the sliders 11 will drive the corresponding two connecting plates 7 to move synchronously, which is conducive to improving the actual adjustment stability.

[0036] Specifically, a groove 10 adapted to the placement plate 2 is provided in the middle of the bottom end of the clamping plate 3, and the clamping plate 3 is mounted on the placement plate 2 through the groove 10, and the inner wall of the groove 10 is slidably connected to the outer surface of the placement plate 2, which can improve the movement stability of the clamping plate 3 and does not affect the movement of the clamping plate 3 along the placement plate 2;

[0037] Furthermore, stoppers 5 are installed at both ends of the placement plate 2. When the clamping plate 3 moves to both ends of the placement plate 2, the clamping plate 3 contacts the stoppers 5 to reach the maximum clamping specification.

[0038] Furthermore, the opposite surfaces of the two clamping plates 3 are both equipped with clamping pieces 12, and the clamping pieces 12 are rubber clamping pieces, which can improve the clamping stability of the workpiece body 4;

[0039] Furthermore, the placement plate 2 is a rubber pad, which can improve the placement stability of the workpiece body 4, and thus improve the clamping stability of the workpiece body 4;

[0040] Example

[0041] In this embodiment, if Figure 4 As shown, there are two clamping devices, which are arranged opposite to each other, and the workpiece body 4 is arranged between the two clamping devices. The two opposite side surfaces of the workpiece body 4 are respectively in contact with the adjacent placement plates 2, and the two ends of the workpiece body 4 are clamped by two groups of clamping plates 3, which can improve the actual clamping stability. It is also possible to choose to use one clamping device or two clamping devices according to actual usage.

[0042] In summary, the clamping device for processing aluminum alloy workpieces proposed in the utility model drives the bidirectional screw 6 to rotate through the driving part 8, so that the two connecting plates 7 are close to or away from each other, thereby driving the two clamping plates 3 to be close to or away from each other, and realizing the adjustment of the distance between the two clamping plates 3, so as to clamp and position the workpiece bodies 4 of different specifications, and then by installing the placement plate 2 on the clamping surface of the base 1, the placement stability of the workpiece body 4 can be improved. Combined with the design of the inner side clamping piece 12 of the clamping plate 3, the actual clamping and positioning effect can be improved, which is convenient for subsequent processing and operation.
