[0018] The following is combined with Figure 1-4 This application is described in further detail.

[0019] The present application embodiment discloses a slider type automatic pressing device. Figure 1-Figure 4 , a processing table 1 and a support frame 4 and a cylinder 6 installed above the support frame 4. When the device is in use, the cylinder 6 drives the pressing component to move downward to achieve the pressing and limiting of the workpiece placed on the upper surface of the processing table 1;

[0020] At the same time, a fixing frame 7 is installed at the telescopic end of the cylinder 6, and a support shaft 16 is rotatably connected to the lower part of the fixing frame 7. A fixing sleeve 9 is fixedly connected to the outside of the support shaft 16. A T-shaped plate 8 and an arc plate 10 are welded to the upper and lower surfaces of the fixing sleeve 9, respectively. A worm gear 2 is fixedly connected to one end of the support shaft 16, and rectangular fixing plates 17 are fixedly connected to both sides of the fixing frame 7. A worm 15 is rotatably connected between the two rectangular fixing plates 17. By rotating the worm 15, the worm 15 can drive the worm gear 2 to rotate, and then the worm gear 2 is rotated. When rotating, the support shaft 16 can be driven, and then the support shaft 16 drives the fixing sleeve 9 to rotate, and then the fixing sleeve 9 can drive the upper and lower T-shaped plates 8 and the arc plate 10 to flip, and quickly change the shape of the pressing surface to adapt to the pressing of different types of workpieces. An elastic component for limiting the worm 15 is arranged between the upper and outer parts of the two rectangular fixing pieces 17. The elastic component is used to limit the worm 15, so as to prevent the worm 15 from rotating, and ensure the stability of the T-shaped plate 8 and the arc plate 10 after flipping.

[0021] Reference Figure 2 and Figure 4 The elastic component in the device includes two plug rods 13 and two annular sleeves 14 as well as a lower frame plate 12 and an upper frame plate 3. The lower frame plate 12 is fixed between two rectangular fixing plates 17, and the upper frame plate 3 is fixed above the lower frame plate 12. The two annular sleeves 14 are fixed at both ends of the worm 15. The two plug rods 13 are elastically connected to the inside of the upper frame plate 3, and one end of the outer side of the plug rod 13 passes through the top wall of the lower frame plate 12 and is embedded in the annular sleeve 14, so that the plug rod 13 can limit the annular sleeve 14 after rotation, thereby improving the stability of the worm 15 after rotation and ensuring the stable use of the T-shaped plate 8 and the arc plate 10.

[0022] Reference Figure 2 and Figure 4 The elastic component in the device also includes two resistance springs 11, the two ends of the two resistance springs 11 are respectively fixed to the corresponding sides of the insertion rod 13 and the upper frame plate 3, so that the insertion rod 13 can move up and down elastically, so that the annular sleeve 14 can squeeze the insertion rod 13 to move upward when rotating, which is convenient for the rotation of the worm 15.

[0023] Reference Figure 2 and Figure 4 Two inferior arc notches are provided inside the annular sleeve 14, which are matched with the bottom end of the insertion rod 13 in size, so that the annular sleeve 14 can squeeze the embedded part of the insertion rod 13 out of the annular sleeve 14 under the drive of external force, which is convenient for the normal rotation of the worm 15. At the same time, the distance between the two inferior arc notches is 180 degrees, which is convenient for the worm 15 to drive the T-plate 8 and the arc plate 10 to accurately flip 180 degrees, so that the T-plate 8 and the arc plate 10 can be perpendicular to the upper surface of the processing table 1 after flipping, ensuring the pressing effect of the T-plate 8 and the arc plate 10 on the workpiece.

[0024] Reference Figure 1 Limit rods 5 are fixedly connected to both sides of the top wall of the fixing frame 7, and the outside of the limit rods 5 passes through the top of the support frame 4, so that the limit rods 5 can move up and down with the fixing frame 7, thereby improving the stability of the fixing frame 7 as a whole when moving up and down.

[0025] The implementation principle of a slider-type automatic clamping device in an embodiment of the present application is as follows: when in use, the worm 15 is rotated so that the worm 15 can drive the worm wheel 2 to rotate, and then the worm wheel 2 can drive the support shaft 16 when rotating, and then the support shaft 16 drives the fixed sleeve 9 to rotate, and then the fixed sleeve 9 can drive the upper and lower T-shaped plates 8 and the arc plate 10 to flip 180 degrees when rotating, and quickly change the shape of the clamping surface, so that the device can adapt to workpieces with flat surfaces and arc surfaces at the same time.
