[0037] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0038] Example 1

[0039] Please refer to Figure 1-6 A material handling clamp includes a mounting arm 1, one end of which is fixedly connected to a mounting base 2. A first material handling component 3 and a second material handling component 4 are mounted on the mounting base 2. The material handling directions of the first material handling component 3 and the second material handling component 4 are set at 90 degrees.

The second material handling assembly 4 includes a four-jaw cylinder 7, four second grippers 8 installed at the output end of the four-jaw cylinder 7, and a buffer assembly 9 installed on the side of the four-jaw cylinder 7.

[0041] The material handling fixture provided in this embodiment can grip materials from different directions by setting the first material handling component 3 and the second material handling component 4, without the need for frequent fixture replacement. Furthermore, the clamping plate 603 of the first gripper 6 can be adjusted and installed on the connecting plate 602, and the L-shaped clamping plate 803 of the second gripper 8 can be adjusted and installed on the fixing plate 802. By adjusting the position of the clamping plate 603 and the L-shaped clamping plate 803, it can better adapt to gripping materials of different sizes, making it very convenient to use.

[0042] Example 2

[0043] The material handling fixture provided in Example 1 has been further optimized, specifically, as follows: Figure 2 , Figure 3 and Figure 6 As shown, the first gripper 6 includes a horizontal plate 601, a connecting plate 602, and a clamping plate 603. The horizontal plate 601 is fixedly connected to the output end of the two-jaw cylinder 5, and the connecting plate 602 is fixedly connected to the horizontal plate 601. The clamping plate 603 is adjustablely installed on the left side of the connecting plate 602. By adjusting the position of the clamping plate 603, it can better adapt to the gripping of materials of different sizes.

[0044] Clamping blocks 604 are fixedly connected to the four corners of the side where the two clamping plates 603 are close to each other, and clearance grooves 605 are opened in the middle of the side where the two clamping plates 603 are close to each other; the protruding clamping blocks 604 can better contact the material.

[0045] The connecting plate 602 has an elongated hole 6021. A movable block 6022 is slidably connected inside the elongated hole 6021. One side of the movable block 6022 is fixedly connected to the clamping plate 603. A lead screw 6023 is rotatably connected to the inner wall of one side of the elongated hole 6021 via a bearing. The other end of the lead screw 6023 passes through the movable block 6022 and the connecting plate 602 and has a hexagonal groove 6024. The lead screw 6023 is threadedly connected to the movable block 6022. A locking nut can be installed on the lead screw 6023. When not in use, the locking nut can be tightened to prevent rotation.

[0046] When adjusting the position of clamping plate 603 due to changes in material size, a tool is used to rotate hexagonal groove 6024 to rotate lead screw 6023. Since lead screw 6023 is threadedly connected to movable block 6022, and movable block 6022 is slidably connected inside elongated hole 6021, lead screw 6023 can drive movable block 6022 and clamping plate 603 to move during rotation, thereby better adapting to the clamping of materials of different sizes, and the position of clamping plate 603 can be adjusted more precisely through lead screw 6023.

[0047] Example 3

[0048] The material handling fixture provided in Embodiment 1 or 2 can be further optimized, such as... Figure 4 and Figure 5 As shown, the second gripper 8 includes a T-shaped slider 801, a fixed plate 802, and an L-shaped clamping plate 803. The T-shaped slider 801 is fixedly connected to the output end of the four-jaw cylinder 7. The fixed plate 802 is fixedly connected to the lower surface of the T-shaped slider 801. The L-shaped clamping plate 803 is adjustablely installed on the lower surface of the fixed plate 802. By adjusting the position of the L-shaped clamping plate 803, it can better adapt to the gripping of materials of different sizes.

[0049] The upper surface of the fixing plate 802 has two first elongated holes 804. The L-shaped clamping plate 803 has multiple first threaded holes 805 corresponding to the first elongated holes 804. A first adjusting screw 806 is installed between the first elongated holes 804 and the first threaded holes 805. When adjusting the position of the L-shaped clamping plate 803, loosen the first adjusting screw 806, then move the fixing plate 802 so that the first adjusting screw 806 moves in the first elongated holes 804. Then tighten the first adjusting screw 806 to fix the L-shaped clamping plate 803 to the fixing plate 802, so as to better adapt to the clamping of materials of different sizes.

[0050] Example 4

[0051] The material handling fixtures provided in the above embodiments are further optimized, such as... Figure 2 , Figure 4 and Figure 5 As shown, there are two buffer components 9, which are installed on the front and rear sides of the four-jaw cylinder 7. The buffer component 9 includes a U-shaped frame 901 fixedly connected to the front and rear sides of the four-jaw cylinder 7. Support rods 902 are adjustablely installed on both the left and right sides of the U-shaped frame 901. An installation cylinder 903 is installed at the end of the support rod 902 away from the U-shaped frame 901. A slide rod 904 is slidably inserted into the installation cylinder 903. A fixing block 905 is fixedly connected to the bottom end of the slide rod 904 and a spring 906 is sleeved on its outer surface. A limit slider is fixedly connected to the outer surface of the slide rod 904 inside the installation cylinder 903 to prevent the slide rod 904 from detaching from the installation cylinder 903.

[0052] The buffer assembly 9 is elastic. When the fixed block 905 contacts the material, the slide bar 904 can slide upward and compress the spring 906. Then the material moves between the four L-shaped clamps 803 for clamping. When the material is released, the restoring force of the spring 906 can cause the material to detach from the four L-shaped clamps 803, preventing the material from getting stuck.

[0053] The mounting cylinder 903 is threadedly connected to the support rod 902. A hexagonal block 907 is fixedly connected to the bottom end of the mounting cylinder 903. The position of the fixing block 905 can be adjusted by the hexagonal block 907 to better remove the material.

[0054] The support rod 902 has a second strip hole 908, and the U-shaped frame 901 has multiple second threaded holes 909. A second adjusting screw 910 is installed between the second strip hole 908 and the second threaded hole 909. When the material size changes, the position of the mounting cylinder 903 is adjusted by loosening the second adjusting screw 910, then the support rod 902 is opened, so that the second adjusting screw 910 moves in the second strip hole 908. Then the second adjusting screw 910 is tightened to fix the support rod 902 and the U-shaped frame 901, thereby adjusting the position of the fixing block 905.
