DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3 A jig for detecting the opening of an inner clamp ring comprises a test bench 5, a bottom plate 7 is fixedly arranged at the top edge of the test bench 5, a top pressure ring 6 is fixedly arranged on the top of the bottom plate 7 by bolts, a receiving groove 61 is provided at the bottom of the top pressure ring 6, and notches are provided on the sides of the top pressure ring 6 and the bottom plate 7, and both ends of the receiving groove 16 extend into the sides of the notch. A worker can use pliers to press the inner clamp ring into the receiving groove 61 and make the opening of the inner clamp ring face the opening position of the top pressure ring 6.

[0021] A docking frame 8 is fixedly provided at the opening position of the bottom plate 7, and a substitute detection component for quickly detecting the opening of the inner retaining ring is provided on the side of the docking frame 8. A column 2 is movably inserted into the test bench 5 on one side of the bottom plate 7, and a horizontal auxiliary cylinder 1 is fixedly provided horizontally on the top of the column 2. The column 2 is fixedly provided with a first stopper 3 and a second stopper 4 on the upper and lower surfaces of the test bench 5 in sequence. The thickness of the gap between the first stopper 3 and the second stopper 4 is much larger than the thickness of the test bench 5 surface. The first stopper 3 and the second stopper 4 allow the column 2 to move within a certain range in the vertical direction. When the second stopper 4 contacts the bottom surface of the test bench 5, the test arm of the vernier caliper moves up to the extreme position, which does not hinder the inner retaining ring from extending into the accommodating groove 61.

[0022] The substitute detection assembly includes a quick indicating rod 12, a shift block 13, and a shift screw 10. One end of the shift screw 10 is rotatably connected to the side of the fixed frame 11, and the other end of the shift screw 10 is fixedly provided with a rocker. The other end of the fixed frame 11 is movably inserted into the docking frame 8. The outer wall of the shift screw 10 is threaded with a shift block 13, and the top of the shift block 13 is fixedly provided with a quick indicating rod 12. Therefore, the entire substitute detection assembly can be quickly removed from the entire detection fixture, which is convenient for maintenance and repair.

[0023] The quick indicating rod 12 has an isosceles trapezoidal cross-section when viewed from above. Indicating scales 121 are equidistantly arranged on the top of the quick indicating rod 12. The end of the quick indicating rod 12 close to the docking frame 8 is the narrowest end. The indicating scales 121 are actually arranged with units, generally millimeters.

[0024] A docking hole 9 is provided at the center position of the side of the docking frame 8, and one end of the shift screw 10 is movably inserted into the docking hole 9. The diameter of the docking hole 9 is equal to the maximum outer diameter of the shift screw 10. A vertical handle 21 is fixedly provided on the side of the column 2, and a fixing bolt 22 is threaded into the edge position of the side of the horizontal auxiliary tube 1. The vertical handle 21 is used to lift the column 2, and the fixing bolt 22 fixes the vernier caliper on the horizontal auxiliary tube 1. A rectangular groove with the same cross-sectional shape and size as the horizontal arm of the vernier caliper is provided on the side of the horizontal auxiliary tube 1.

[0025] It should be supplemented that the long axis of the quick-indicating rod 12 passes through the center of the bottom plate 7 .

[0026] The specific implementation steps and principles of the utility model are as follows:

[0027] When it is necessary to use the vernier caliper, insert the horizontal arm of the vernier caliper into the horizontal auxiliary cylinder 1, and tighten the fixing bolt 22. Lift the column 2 through the upper handle 21 until the bottom of the second stop block 4 contacts the bottom of the test bench 5. At this time, the test arm of the vernier caliper has not extended into the notch of the top pressure ring 6. The tester uses a tool to insert the inner clamping ring into the accommodating groove 61, and align the opening of the inner clamping ring with the opening of the top pressure ring 6, and then lower the column 2. At this time, the test arm of the vernier caliper extends into the opening of the inner clamping ring for testing.

[0028] When the substitute test assembly is needed, the shift screw 10 is rotated manually, and the shift screw 10 drives the quick indicating rod 12 to gradually insert into the opening of the inner clamp ring through the shift block 13 until the two sides of the quick indicating rod 12 contact the opening of the inner clamp ring.

[0029] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
