[0024] like Figures 1 to 3 As shown, a workpiece clamping tool includes a side plate 3, a clamping block 1 is fixedly provided on the side of the side plate 3, the clamping block 1 is provided with a movable groove, a movable block 2 is installed in the movable groove, and a space is left between the movable block 2 and the side wall of the movable groove to form a clamping groove 8, the clamping groove 8 is used to place the workpiece, a driving shaft 5 is installed between the clamping block 1 and the side plate 3, the driving shaft 5 is connected to the clamping block 1, and the workpiece placed in the clamping groove 8 is clamped and fixed by rotating the driving shaft to drive the movable block 2 to move.

[0025] The movable block 2 is spaced apart from the inner wall of the movable groove. The clamping block 1 comprises two upright panels, the panel closer to the side panel 3 being lower than the other panel. A notch is formed between the top of the shorter panel and the adjacent side wall of the clamping block 1 or side panel 3. A protrusion is provided on the end of the movable block 2 closer to the shorter panel. The protrusion fits within the notch, leaving a space between the side wall of the protrusion and the adjacent side wall of the clamping block 1 or side panel 3. This space forms a clamping groove 8 for placing a workpiece. Once the workpiece is placed in the clamping groove 8, the protrusion moves to clamp and secure the workpiece.

[0026] like Figure 5 As shown, an elastic component is installed between the movable block 2 and the movable groove. When the clamping block 1 is in a loose state, the clamping groove 8 is opened by the elastic component.

[0027] The movable block 2 is provided with a movable hole. The elastic component includes a sliding post 10 slidably installed in the movable hole. One end of the sliding post 10 is provided with an end head. The sliding post 10 is sleeved with a spring 11.

[0028] One end of the spring 11 contacts the movable block 2 , and the other end contacts the end head.

[0029] In this embodiment, a plurality of clamping blocks 1 are provided, three clamping blocks 1 are arranged side by side, and the movable blocks 2 are arranged corresponding to the clamping blocks 1 .

[0030] The clamping block 1 is provided with a through hole, and the driving shaft 5 is rotatably installed in the through hole. The end of the driving shaft 5 away from the side plate 3 is provided with a limited end, and the closing operation of the clamping groove 8 is achieved by pulling the rotating shaft 6 toward the side plate 3.

[0031] A plurality of drive shafts 5 are provided corresponding to the clamping blocks 1 , and the plurality of drive shafts 5 are threadedly connected.

[0032] like Figure 4 As shown, specifically, the clamping block 1 is provided with a circular hole, through which the drive shaft 5 slides, and the limiting end of the drive shaft 5 is used to prevent the drive shaft 5 from sliding out of the clamping block 1. The end of the drive shaft 5 provided with the limiting end is provided with a threaded hole, and the other end of the drive shaft 5 is provided with a threaded section, which is threadedly installed in the threaded hole.

[0033] The end of the drive shaft 5 passes through the side plate 3, and a rotating shaft 6 is installed at the end of the drive shaft 5. The rotating shaft 6 is arranged perpendicular to the drive shaft 5. An adjusting block 4 is fixedly installed on the side wall of the side plate 3. The adjusting block 4 is matched with the rotating shaft 6. The rotating shaft 6 rotates along the adjusting block 4 to realize the closing operation of the clamping groove 8.

[0034] The adjusting block 4 is cylindrical in shape and is provided with a circular hole. The rotating shaft 6 passes through the circular hole. One side of the adjusting block 4 is fixedly connected to the side plate 3. The other side of the adjusting block 4 is provided with a guide surface. The position of the rotating shaft 6 corresponds to the guide surface. When the rotating shaft 6 moves along the guide surface to the side of the adjusting block 4 away from the side plate 3, the clamping groove 8 is closed.

[0035] This clamping tool is used to clamp the needle plate 12 with the pin 13. Figure 6 As shown, after the needle plate 23 is clamped and fixed, it is convenient to remove the pins 13 on the needle plate 12.

[0036] During use, the needle plate with the needle is placed on the clamp, and the rotating shaft 6 is rotated so that the finger and the side of the adjustment block 4 away from the side plate 3 are in contact. During the rotation of the rotating shaft 6, the driving shaft 5 moves toward the side plate 3, and the driving shaft 5 drives the movable block 2 to move until the workpiece is clamped and fixed. At this time, the needle removal operation can be performed. After the needle removal operation is completed, the rotating shaft 6 is rotated in the opposite direction and moves to the curved surface of the adjustment block 4 close to the side plate 3. During this process, the elastic force of the retracting spring 11 acts, and the protrusion of the movable block 2 moves in the direction away from the side plate 3, realizing the release operation of the workpiece, and the workpiece can be removed.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
