The invention will be further described with reference to the accompanying drawings and the detailed description below:
as shown in fig. 1 and 2, the tool for preventing the error installation of the multi-level open seal ring comprises a support table 10, wherein the outer side of the support table 10 is a truncated cone-shaped structure, and a workpiece insertion hole 12 is formed in the bottom of the support table 10;
a base 20 is arranged below the supporting platform 10, the base 20 is connected with the outer side of the supporting platform 10 through a connecting column 21, a mistake proofing hole 22 coaxial with the workpiece inserting hole 12 is formed in the base 20, and an avoiding groove 23 is formed in the connecting column 21;
a screw hole 11 coaxial with the workpiece insertion hole 12 is arranged in the middle of the support table 10, a stage adjusting column 30 is arranged in the screw hole 11, and the stage adjusting column 30 comprises a limiting table 32 in clearance fit with the workpiece insertion hole 12 and an adjusting stud 31 in threaded engagement with the screw hole 11;
the inner diameter of the mistake-proofing hole 22 is larger than or equal to the upper limit of the outer diameter of the opening sealing ring 40 after the opening sealing ring is normally closed.
The procedure used in this example is as follows:
s1, inserting the workpiece 50 into the workpiece insertion hole 12 from below the base 20 through the mistake proofing hole 22,
and the workpiece 50 is tightly attached to the limit table 32;
s2, rotating the level adjusting column 30 to align the level groove of the opening sealing ring 40 to be installed of the workpiece 50 with the avoidance groove 23;
s3, sleeving the split sealing ring 40 from the top (small end of the frustum) of the support table 10, and aligning the split sealing ring 40 with the connecting column 21;
s4, pushing the open sealing ring 40 towards the bottom (large end of the frustum) of the support platform 10, separating the opening of the open sealing ring 40 under the expansion of the frustum, then separating the open sealing ring from the support platform 10 at the position of the avoiding groove 23, sleeving the open sealing ring 40 into the stage groove of the workpiece 50 at the moment, and closing the opening of the open sealing ring 40;
s5, the workpiece 50 is taken out from the error-proofing hole 22.
Because the material of the split seal ring 40 has the characteristic of high brittleness, the split is easily caused when the split is closed in installation, the outer diameter of the closed split seal ring is larger than the designed size due to the fact that scraps are mixed in the closed part, or the scraps are clamped between the split seal ring 40 and the workpiece 50, and the split seal ring 40 is not concentric with the workpiece 50.
In this embodiment, the inner diameter of the error-proof hole 22 is greater than or equal to the upper limit of the outer diameter of the split seal ring 40 after the split seal ring 40 is normally closed, in this example, the outer diameter of the split seal ring 40 after the split seal ring is normally closed is 80+0.05/-0.05mm, and the inner diameter of the error-proof hole 22 is 80+0.1/+0.05 mm. When the size of the opening sealing ring 40 after being closed is larger than the upper limit of the outer diameter size after being normally closed, and the force for taking the opening sealing ring 40 out of the mistake-proofing hole 22 is abnormal, the installation mistake can be judged, and the inspection is needed to prevent the defective products from flowing out.
Further, the height of the avoiding groove 23 is 1.0 to 1.8 times of the thickness of the opening sealing ring 40.
The height of the avoidance groove 23 is between 1 and 2 thicknesses of the open sealing ring 40, so that repeated installation in installation can be prevented.
Further, as shown in fig. 2, 3 and 4, a wedge-shaped groove 24 is arranged on the base 20 at a position away from the connecting column 21, and the wedge-shaped groove 24 makes the mistake proofing hole 22 be in a non-annular closed structure.
When the outer diameter of the closed portion of the split seal ring 40 is larger than the inner diameter of the error-proofing hole 22 due to the inclusion of debris and cannot be compressed, the workpiece 50 cannot be taken out. At this time, the wedge block 91 is pressed into the wedge groove 24 to expand the mistake-proofing hole 22, thereby facilitating the removal of the workpiece 50 with an abnormal installation.
Further, in order to reduce the manufacturing difficulty, the support table 10 and the connection column 21 and the base 20 and the connection column 21 are fixed by welding and/or screw connection.
