[0006] By adopting the above technical scheme, when in use, the retainer ring is sleeved on the positioning column, and then the pressure plate is used to press the plurality of retainer rings, so that the plurality of retainer rings can be fixed, and the machining efficiency is high.

[0007] In a preferred example, the bottom plate can be further provided with a clearance groove, the clearance groove penetrates the bottom plate, and the clearance groove corresponds to the positioning column.

[0008] By adopting the above technical scheme, the presence of the clearance groove enables the molybdenum wire to pass through the bottom plate to machine the retainer ring.

[0009] In a preferred example, the width of the clearance groove can be not less than the width of the displacement groove.

[0010] By adopting the above technical scheme, the molybdenum wire machining is further facilitated.

[0018] By adopting the technical scheme, when the check ring has an inner diameter that is too large or too small, when one side abuts against the positioning column, the other end will form a protrusion or depression on the vertical plane formed by the remaining check rings, so that the check ring that does not meet the requirements can be removed in this way.

[0019] In a preferred example, the application can be further configured to: the adjusting member includes an adjusting rod and an adjusting slot, the adjusting slot is covered with a deformation layer, and the deformation layer is used to contact the check ring under the action of pressure.

[0020] By adopting the technical scheme, during the adjustment of the check ring, gas is introduced into the adjusting slot, the presence of the gas causes the deformation layer to deform and contact the check ring, thereby achieving the purpose of adjusting the position of the check ring.

[0021] In a preferred example, the application can be further configured to: after arrangement, judge whether the check ring has protrusion or depression, fixedly connect the pressing plate and the positioning column, and press the uppermost check ring, after pressing, cancel the pressure on the deformation layer, restore the deformation layer, and take out the adjusting member from the displacement slot.

[0022] By adopting the technical scheme, after the position of the check ring is adjusted in place, the check ring is pressed by the pressing plate, so as to achieve the purpose of fixing the check ring. After the check ring is fixed, the gas in the adjusting groove is discharged, so that the deformation layer is not in contact with the check ring, and then the adjusting piece is taken out from the displacement groove.

[0026] The present application will be further described in detail below in combination with the drawings.

[0027] Reference Figure 1 and Figure 2 A check ring clamping device disclosed by the present application comprises a bottom plate 1, the bottom plate 1 is provided with at least one positioning column 4, in the present embodiment, there are four positioning columns 4, the positioning column 4 is provided with a plug-in rod 41, the plug-in rod 41 is annular, more specifically, such as oval, racetrack shape. The bottom plate 1 is provided with a mounting hole 12 matched with the plug-in rod 41, the mounting hole 12 is a non-circular hole and penetrates the bottom plate 1. The bottom plate 1 is further provided with a let go groove 11 penetrating the bottom plate 1, the let go groove 11 corresponds to the positioning column 4 one by one and communicates with the corresponding mounting hole 12.

[0028] The positioning column 4 is further provided with a pressing assembly 2, the pressing assembly 2 comprises a pressing plate 21 and a fixing piece 22, in the present embodiment, the fixing piece 22 is a bolt, the pressing plate 21 is fixedly connected with the positioning column 4 through the bolt. The pressing plate 21 and the positioning column 4 are both provided with a displacement groove 3. The width of the let go groove 11 is not less than the width of the displacement groove 3. In the present embodiment, the width of the let go groove 11 is equal to the width of the displacement groove 3.

[0029] When the check ring is sleeved on the positioning column 4, according to production requirements, a certain number of check rings are sleeved on the positioning column 4, at this time, the upper surface of the uppermost check ring protrudes from the upper surface of the positioning column 4, then the pressing plate 21 is connected with the positioning column 4, so that the pressing plate 21 is in contact with the check ring and exerts force on the check ring, at this time, the check ring can still move under the action of external force;

[0030] The position of the check ring is adjusted by the adjusting piece, so that the check rings are arranged in order. The adjusting piece includes an adjusting rod and an adjusting groove. A deformation layer is arranged on the adjusting groove. The deformation layer can be made of rubber and can be arc-shaped. The adjusting groove is connected to an air source. Under the action of the air source, the deformation layer deforms. When the deformation layer contacts the check ring, the check ring moves away from the deformation layer under the action of the pressure and abuts against the positioning column 4 on the side away from the deformation layer.

[0031] The arranged check rings are judged to see whether any check ring protrudes or is recessed. If so, the corresponding check ring is removed. In this step, if the check ring is a non-opening check ring, it is judged whether the check ring protrudes or is recessed on the cylindrical surface formed by other check rings. If the check ring is an opening check ring, it is judged by the deformation degree of the deformation layer at the opening of the check ring. When the opening check ring is used, the area of the deformation layer is greater than the groove width of the adjusting groove, that is, the deformation layer can extend to the opening of the opening check ring. When the deformation layer is subjected to pressure, the deformation can fine-tune the opening position of the check ring, so that the opening position has higher consistency in the vertical direction.

[0032] If no check ring protrudes or is recessed, the pressing plate 21 and the positioning column 4 are fixedly connected, and the pressing plate 21 is pressed against the uppermost check ring. After pressing, the pressure on the deformation layer is removed, the deformation layer is restored, and the adjusting piece is taken out of the displacement groove 3.

[0033] The implementation principle of the embodiment is that the check ring is sleeved on the positioning column 4, and then the pressing plate 21 applies pressure to the check ring and fixes it, so that multiple check rings can be machined, thereby improving work efficiency.

[0034] The embodiments of the specific embodiment are preferred embodiments of the application, but do not limit the protection scope of the application. Therefore, equivalent changes made according to the structure, shape, principle of the application should be covered within the protection scope of the application.
