[0031] like Figure 1 and Figure 2As shown, the utility model provides a clamping and grading device for a seal, comprising a clamping mechanism 10, wherein a movable end 20 is movably provided at one end of the clamping mechanism 10, a head 30 is movably provided at one end of the movable end 20, a driving mechanism 40 is fixedly provided on the inner wall of the clamping mechanism 10, an output end of the driving mechanism 40 is fixedly connected to the movable end 20, the movable end 20 slides along the connection between it and the clamping mechanism 10 and then is sleeved with the clamping mechanism 10 to form a folding storage structure, and the head 30 rotates around the connection between it and the movable end 20 and is located on the extension line of the movable end 20 to form a head extension structure.

[0032] The utility model adopts a movable stacking manner to form a retractable clamping structure, which is beneficial to the tapered grading form and cooperates with the movable adjustable external fixing structure, and can be suitable for sealing parts of more sizes to perform multi-group graded clamping and fixing. When the seal is installed, the seal can be conveniently installed and fixed through a head of a smaller size, and can be movably retracted and retracted as needed. At the same time, the head follows the telescopic rotation to adjust the angle, and can be rotated to open to play a limiting role, which is convenient for limiting and fixing the seal during the contraction process, and is beneficial to graded adjustment and clamping of multiple groups of seals of different specifications, and is beneficial to simultaneous processing of multiple groups of seals, reducing the steps of disassembly and assembly, and is beneficial to improving processing efficiency.

[0033] The telescopic structure is divided into multiple stages in a conical form, which is convenient for adjustment according to the size of the seal. Multiple groups of seals of different specifications can be clamped and fixed in stages, and the height and size of the clamping and grading device can be adjusted by telescopic means according to usage requirements, thereby improving flexibility.

[0034] like Figure 2 As shown, the movable end 20 includes a clamping middle section 21, one end of the clamping middle section 21 is movably provided with a clamping top section 22, and the inner wall of the clamping top section 22 is fixedly connected with a partition plate 23;

[0035] The output end of the driving mechanism 40 is disposed through the inner wall of the clamping middle section 21 and is fixedly connected to the partition plate 23 .

[0036] The driving mechanism 40 drives the clamping top section 22 to be telescopically adjusted, and the contraction of the clamping top section 22 further drives the clamping middle section 21 to be folded, which is beneficial for completing the telescopic structure through a single set of drives and for adjusting the contraction state according to usage requirements, thereby facilitating processing and use.

[0037] like Figure 2 and Figure 3 As shown, the head 30 includes a movable rod 32, one end of which is rotatably connected to the clamping top section 22 via a rotating shaft 31, and a return spring is provided at the connection position between the rotating shaft 31 and the clamping top section 22;

[0038] Among them, a double-headed motor 33 is fixedly installed on the inner wall of the clamping top section 22 above the partition 23, and the output shaft of the double-headed motor 33 is fixedly connected to a connecting rope 34 through a coupling, one end of the connecting rope 34 is fixedly connected to one end of the movable rod 32, and one side of the movable rod 32 and the inner wall of the clamping top section 22 are both provided with a limiting ring 35 that is sleeved on the outside of the connecting rope 34.

[0039] When the seal is disassembled and installed, the connecting rope 34 is reeled in by the double-headed motor 33 to rotate the movable rod 32 to a vertical state. The movable rod 32 is on the extension line of the clamping top section 22. The seal is disassembled or installed through the minimum width range of the top end of the movable rod 32, which is convenient and quick to install and use.

[0040] When the clamping top section 22 contracts, the connecting rope 34 is unwound by the double-headed motor 33, so that the movable rod 32 rebounds to the initial state through the return spring, and the movable rod 32 is perpendicular to the clamping top section 22, which is beneficial to play a blocking and limiting role during the contraction of the clamping top section 22, and is beneficial to drive the seal to be clamped and fixed.

[0041] like Figure 2 and Figure 3 As shown, the clamping mechanism 10 includes a mounting seat 11, on which a clamping bottom section 12 is fixedly connected, and the height of the clamping bottom section 12 is greater than the height of the clamping middle section 21 and greater than the height of the clamping top section 22;

[0042] Among them, the inner wall of the clamping bottom section 12, the inner wall of the clamping middle section 21 and the inner wall of the clamping top section 22 are all fixedly connected to the limiting mechanism 60, and the limiting mechanism 60 includes an electric push rod 61, and the output end of the electric push rod 61 is fixedly connected to the limiting strip 62.

[0043] By combining the clamping bottom section 12, the clamping middle section 21 and the clamping top section 22 into a tapered graded clamping structure, it can be suitable for clamping seals of more sizes and specifications, and is convenient for clamping and fixing multiple groups of seals at the same time, thereby helping to improve work efficiency.

[0044] During the clamping process, the outer side of the seal is limited and fixed by the limiting mechanism 60, and the clamping bottom section 12, the clamping middle section 21 and the clamping top section 22 are used to achieve the clamping purpose, and the seal is adjusted according to the size and thickness of the seal. The limiting strip 62 is driven by the electric push rod 61 to perform telescopic adjustment, thereby facilitating the adjustment of the fixation of the seal.

[0045] like Figure 2 , Figure 3 and Figure 4As shown, the bottom ends of the clamping middle section 21 and the clamping top section 22 are both provided with a connecting piece 50, and the connecting piece 50 includes a fixed sleeve 51, one end of the fixed sleeve 51 is movably connected to a movable sleeve rod 52, one end of the movable sleeve rod 52 is connected to the inner wall of the fixed sleeve 51 through a spring 53, and the other end of the movable sleeve rod 52 is fixedly connected to a slider 54;

[0046] The inner wall of the clamping bottom section 12 and the inner wall of the clamping middle section 21 are both provided with sliding grooves matching the sliding block 54 .

[0047] During the extension and retraction of the clamping top section 22 and the clamping middle section 21, the connecting piece 50 is respectively slidably connected to the clamping middle section 21 and the clamping bottom section 12, which is beneficial to play the role of connection and limitation, and at the same time, the clamping top section 22 is beneficial to drive the clamping middle section 21 to retract during the contraction process, and the connecting piece 50 follows the contraction to extend and retract, which is beneficial to improve the stability of the clamping top section 22 and the clamping middle section 21 during the contraction process.

[0048] When the clamping top section 22 and the clamping middle section 21 contract, they are slidably connected through the slider 54, and the elastic expansion and contraction of the spring 53 drives the slider 54 and the movable sleeve rod 52 and the fixed sleeve 51 to move and expand, which is beneficial for following the expansion and contraction of the clamping top section 22 and the clamping middle section 21 for adjustment, so that they can play a connecting role and perform sliding adjustment at the same time.
