Description

Technical Field

[0001] This utility model relates to the field of clamping equipment technology, specifically to an M-type sealing ring clamping device. Background Technology

[0002] According to the Chinese utility model patent with publication number CN216803166U and title: "A Curved Part Clamping Device", the patent uses two fixing blocks set on the top of the claw to cooperate with each other to clamp the C-shaped sealing ring in a wrapping manner, and uses laser welding to weld the joint into shape.

[0003] Because the M-type sealing ring has elastic properties, the pressure needs to be evenly distributed. Using this wrapping clamping method will cause deformation and damage to the sealing ring. Therefore, we propose an M-type sealing ring clamping device. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] See attached document Figure 1-3An M-type sealing ring clamping device includes a base 1, a lower fixing member 2 sleeved on the base 1, the shape of the lower fixing member 2 being adapted to the bottom shape of the sealing ring, the lower fixing member 2 and the base 1 being concentrically arranged, at least two clamping mechanisms are also provided on the side wall of the base 1, the clamping mechanisms are connected together by a fixing plate 5 to support the overall structure, the clamping mechanism includes a fixing unit 3 and a pressing unit 4, the fixing unit 3 includes a fixing base 31, the fixing base 31 is fixedly installed on the base 1, the fixing base 31 is also installed with a compensation frame 32, the height of the compensation frame 32 is the same as the highest point of the lower fixing member 2, when the pressing unit 4 approaches the fixing unit 3 to clamp the sealing ring, it prevents the pressing unit 4 from overstretching and avoids damage to the sealing ring, a hexagonal bolt 33 is passed through the compensation frame 32, the hexagonal bolt 33 extends downward through the compensation frame 32 and extends out of the fixing base 31, the hexagonal bolt 33 is also threaded with a nut 34, the hexagonal bolt 33 is controlled to rise and fall within the fixing base 31 and the compensation frame 32 by rotating the nut 34;

[0026] Furthermore, the pressing unit 4 includes a connecting rod 41 and an upper fixing member 42. The shape of the upper fixing member 42 is adapted to the open shape of the sealing ring. The lower fixing member 2 and the upper fixing member 42 are close to each other and have a gap to accommodate the sealing ring. The upper fixing member 42 has recesses 421 on both sides, which are adapted to the side positions of the sealing ring. A hexagonal limiting groove 43 is installed on the bottom of the connecting rod 41. The hexagonal limiting groove 43 is engaged with the hexagonal bolt 33. When the nut is rotated, the hexagonal bolt 33 is engaged in the hexagonal limiting groove 43, that is, the hexagonal bolt 33 will not be affected by the rotation of the nut. The nut rotates and the rod 41 rotates accordingly. The hexagonal limiting groove 43 and the connecting rod 41 form a cavity to accommodate the hexagonal part of the hexagonal bolt 33. The protrusion at the edge of the cavity extends towards the axis of the hexagonal bolt 33, moving and locking the hexagonal part of the hexagonal bolt 33. The connecting rod 41 can rotate around the cavity, making it convenient to place and remove the sealing ring. The lifting and lowering of the hexagonal bolt 33 can drive the connecting rod 41 to lift and lower, thereby driving the upper fixing part 42 to clamp towards the lower fixing part 2. The sealing ring is fixed by clamping from both above and below, avoiding the damage to the sealing ring caused by using a wrapping clamping method.
