[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, a clamping device for mechanical design and manufacturing includes a box body 1, an inner side wall of the box body 1 is provided with a first slide groove 2, an inner side wall of the first slide groove 2 is opened with a receiving hole 3, a servo motor 4 is arranged in the receiving hole 3, a rotating rod 5 is arranged between the servo motor 4 and the opposite inner wall of the first slide groove 2, the rotating rod 5 is provided with two sections of threaded sections 6 with different directions, the threaded sections 6 on both sides are provided with driven blocks 7, and the end faces of the driven blocks 7 are provided with grasping components 8. The servo motor 4 rotates the rotating rod 5 to make the driven blocks 7 move on the threaded sections 6, and the directions of the threaded sections 6 on both sides are different, so that the driven blocks 7 on both sides can be moved closer to or away from each other to achieve the effect of adjusting the spacing.

[0023] In this embodiment, the gripping assembly 8 includes a fixed vertical plate 9, and the side walls near the top and bottom of the fixed vertical plate 9 are connected to rotating blocks 11 through a first rotating shaft 10. The rotating blocks 11 on both sides are connected to clamping blocks 13 through a second rotating shaft 12. A guide rod 14 is provided between the clamping blocks 13 on both sides. When the rotating block 11 rotates through the first rotating shaft 10, the clamping block 13 can be driven to rotate. Under the action of the second rotating shaft 12, the clamping block 13 can always move vertically along the guide rod 14 when approaching each other.

[0024] In this embodiment, the inner side walls of the box body 1 are symmetrically provided with second slide grooves 15 below the first slide groove 2. A plurality of slide blocks 16 are provided in the second slide grooves 15. Transmission components 17 are connected between the slide blocks 16. The slide blocks 16 slide in the second slide grooves 15 to adjust the spacing between the transmission components 17 on both sides to adapt to the length of the workpiece.

[0025] In this embodiment, the transmission assembly 17 includes a transmission block 18, which is provided with a groove 19. Transmission rollers 20 are evenly spaced in the groove 19. Belts 21 are provided at both ends of the transmission rollers 20. The belts 21 drive the transmission rollers 20 to rotate to achieve transmission.

[0027] It should be noted that the utility model is a clamping device for mechanical design and manufacturing. When in use, according to the length of the workpiece, the sliders 16 on both sides slide synchronously in the second slide groove 15 to drive the transmission assembly 17 to move until the two ends of the workpiece are in contact with the inner wall of the storage groove 23. The belt 21 drives the transmission roller 20 to rotate to transport the workpiece to the gripping assembly 8, so that automatic loading can be achieved and manpower can be saved. The servo motor 4 rotates to rotate the rotary rod 5, so that the driven block 7 can move on the threaded section 6 to adjust the spacing between the driven blocks 7 on both sides to adapt to the length of the workpiece. At the same time, the rotating block 11 rotates on both sides of the fixed vertical plate 9 through the first rotating shaft 10, so as to drive the clamping blocks 13 to approach each other, and under the action of the second rotating shaft 12, the rotating block 11 can always move vertically along the guide rod 14, so that the spacing between the clamping blocks 13 on both sides can be adjusted according to the thickness of the workpiece to reduce limitations.
