Description

Technical Field

[0001] The utility model relates to the field of mechanical seal production, in particular to a wear-resistant mechanical seal detection tool. Background Art

[0002] After searching the patent document with the announcement number CN221959945U, the support plate is moved downward by the screw rod to make the clamping plate clamp and fix the mechanical seal to be tested, and then the friction wheel is made close to the clamped seal end wall by adjusting the position of the upper seat to rub the seal end wall, so as to achieve the purpose of testing the wear resistance of the seal;

[0003] When testing the seal, the patent document requires rotating the screw to allow the two clamping plates to clamp and fix the seal to be tested. Before testing, the position of the upper seat and the slider needs to be adjusted to test the wear resistance of the end wall of the seal. This will undoubtedly increase the time for installing and removing the seal from the testing tooling, and may also reduce the speed of the entire seal testing. Utility Model Content

[0027] The utility model is further described below in conjunction with the accompanying drawings:

[0028] like Figure 1-Figure 9 As shown, a wear-resistant mechanical seal detection tool comprises a test mechanism 3 for detecting the wear-resistant mechanical seal and a detection tool mechanism 1 for clamping and fixing the mechanical seal 4;

[0029] In this embodiment, the detection tooling mechanism 1 includes a detection transposition frame 12, a detection L frame 11 is fixed in the middle of the detection transposition frame 12, a detection tooling transposition seat 15 is slidably connected in the detection transposition frame 12, a tooling base 16 is slidably connected to the top of the detection tooling transposition seat 15, guide rods 17 are fixed on both sides of the tooling base 16, a tooling pressure seat 19 is provided on the upper side of the tooling base 16, and a fixing sleeve 191 for sleeved on the two guide rods 17 is provided on both sides of the tooling pressure seat 19, and the fixing sleeve 1 A through hole is provided on 91 for the guide rod 17 to pass through, a reset spring 192 is fixed at the lower end of the fixing sleeve 191, an arc-shaped push strip 18 is fixed on one side of the two tooling bases 16, a detection push seat 13 for pushing the arc-shaped push strip 18 is provided on the top of the detection tooling transposition seat 15, and a detection pressure seat 14 for pushing the tooling pressure seat 19 downward is fixed on the detection pressure seat 14, and two sets of guide rails corresponding to the two tooling bases 16 are provided on the front and rear sides of the top of the detection tooling transposition seat 15. The bottom is provided with a guide groove for sliding on the guide rail, the detection transposition frame 12 is fixed with a T-shaped rail near the test mechanism 3, the bottom of the detection tooling transposition seat 15 is provided with a T-shaped slide groove at the T-shaped rail, and one side of the detection tooling transposition seat 15 is provided with a driving mechanism 2 for driving it to move forward and backward, and the two tooling bases 16 on its upper side are driven to be alternately located under the detection L frame 11 through the forward and backward movement of the detection tooling transposition seat 15. In this process, the dynamic ring and the static ring of the mechanical seal 4 are respectively placed in the two tooling bases 16. When any detection pressure seat 14 moves to the lower side of the detection L frame 11, the arc-shaped push bar 18 is pushed by the detection push seat 13 to allow the tooling base 16 to drive the tooling pressure seat 19 to slide toward the test mechanism 3. At the same time, the detection pressure seat 14 will push the top of the tooling pressure seat 19, so that the tooling pressure seat 19 follows the fixed sleeve 191 to move downward along the guide rod 17, and the reset spring 192 is compressed at the same time, and then the mechanical seal 4 to be tested is clamped and fixed in the entire detection tooling.

[0030] In this embodiment: the driving mechanism 2 includes a screw rod 21, which is rotatably connected to the detection transposition frame 12, and a driving motor 22 is fixedly provided at the input end of the screw rod 21. A threaded hole for cooperating with the screw rod 21 is provided on the detection tooling transposition seat 15. The screw rod 21 is driven by the rotating part of the driving motor 22 to rotate alternately forward and reverse, thereby driving the detection tooling transposition seat 15 to move alternately front and back.

[0031] In this embodiment: the testing mechanism 3 includes a testing frame 31, which is fixed in the middle position of the detection transposition frame 12, and the detection L frame 11 is arranged opposite to the testing frame 31, a testing limit seat 32 is provided on the inner side of the testing frame 31, and testing slide bars 33 are fixed at the four corner positions of the testing limit seat 32, and the testing slide bars 33 are slidably connected to the testing frame 31, one side of the testing limit seat 32 is rotatably connected to a grinding wheel 35, and the other side of the testing limit seat 32 is fixed with a testing motor 34 for driving the grinding wheel 35 to rotate, and the position where the testing slide bar 33 extends out of the testing frame 31 is provided with a tensioning spring for pulling the testing limit seat 32 to move toward the detection L frame 11, the testing limit seat 32 is supported on the testing frame 31 by four testing slide bars 33, and the grinding wheel 35 is driven to rotate by the testing motor 34 on the testing limit seat 32, and in addition, the tensioning spring on the testing slide bar 33 drives the testing limit seat 32 to move toward the clamped mechanical seal 4.

[0032] Working principle: When in use, first place the dynamic ring and the static ring of the mechanical seal 4 to be tested for wear resistance on two tooling bases 16 respectively, and then drive the screw 21 to rotate alternately forward and reverse through the rotating part of the driving motor 22, thereby driving the testing tooling transposition seat 15 to move alternately front and back;

[0033] When the detection tooling transposition seat 15 moves forward, the tooling base 16 on which the moving ring is placed will move forward with the detection tooling transposition seat 15, and at the same time, the tooling base 16 will drive the arc-shaped push strip 18 on one side thereof to move forward from the rear side of the detection push seat 13, and then the moving ring will follow the tooling base 16 and the tooling pressure seat 19 to approach the direction of the testing mechanism 3. As the detection tooling transposition seat 15 continues to move forward, before the moving ring contacts the grinding wheel 35, the top of the tooling pressure seat 19 will abut against the lower side of the detection pressure seat 14, so that the tooling pressure seat 19 will follow the fixed sleeve 191 to move downward along the guide rod 17, and the moving ring is pressed and fixed by the tooling pressure seat 19. As the detection tooling transposition seat 15 continues to move forward, the moving ring clamped by the tooling corresponds to the grinding wheel 35, and the grinding wheel 35 is driven by the test motor 34 to rub the end face of the moving ring. After rubbing for a period of time, the wear amount of the moving ring and the sealing effect are checked;

[0034] In addition, when the dynamic ring test is completed, the detection tooling transfer seat 15 is moved backward to drive the detection pressure seat 14 on the front side to move backward, and the above steps are repeated to clamp the static ring between the tooling base 16 and the tooling pressure seat 19 on the front side, and then the static ring is subjected to end face friction through the testing mechanism 3 to test the wear resistance of the static ring. In addition, when the tooling base 16 on the rear side of the detection tooling transfer seat 15 is moved out of the detection L frame 11, the reset spring 192 pushes the fixed sleeve 191 to allow the tooling pressure seat 19 to move upward along the guide rod 17, and then the dynamic ring that has completed the test is removed, and then a new mechanical seal 4 to be tested is replaced.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
