DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Example 1: Refer to the attached specification Figure 1-5 The utility model is an auxiliary bracket for engine vibration testing, comprising an auxiliary bracket body 1, see Figure 5 The auxiliary support body 1 is internally connected to a step wheel 2, and one side of the step wheel 2 is fixedly connected to a support frame 3, see Figure 1 The outer wall of the support frame 3 is provided with an engine 4, and the outer walls of the support frame 3 and the engine 4 are sleeved with a fixing member 5, and the inside of the fixing member 5 is inserted with a fastening bolt 6, and the fastening bolt 6 is connected to the inside of the support frame 3 through a thread, see Figure 3 The auxiliary bracket body 1 is slidably connected with a pressing piece 7, and the outer wall of the pressing piece 7 is hinged with a telescopic rotating piece 8, which is rotatably connected to the inside of the auxiliary bracket body 1. One end of the telescopic rotating piece 8 is hinged with a connecting block 9, and a spring 10 is fixedly installed on the top of the connecting block 9. A limit rod 11 is inserted into the inside of the connecting block 9 and the spring 10;
[0023] The limiting rod 11 is fixedly connected to the inside of the auxiliary bracket body 1, and the outer wall of the limiting rod 11 is sleeved with a card block 12, and the card block 12 is slidably connected to the inside of the auxiliary bracket body 1. The card block 12 is fixedly installed at one end of the spring 10, and the card block 12 is arranged at the bottom of the support frame 3. The bottom of the pressing piece 7 is provided with a card rod 13, and the card rod 13 is slidably connected to the inside of the auxiliary bracket body 1. An elastic member 14 is provided on one side of the card rod 13, and a support plate 15 is sleeved on the outer wall of the elastic member 14. The support plate 15 is arranged at the bottom of the auxiliary bracket body 1. For details, see Figure 2 A limiting groove 16 and a guide groove 17 are provided on one side of the support plate 15. Figure 5 A card slot 18 is provided on one side of the step wheel 2 , and a connecting piece 19 is fixedly connected to the outer wall of the card block 12 , and the connecting piece 19 is slidably connected to the inside of the auxiliary bracket body 1 .
[0024] It should be noted that, when the staff needs to perform a vibration test on the engine 4, the engine 4 can be moved to the support frame 3, and then the engine 4 can be fixed to the support frame 3 by the fixing member 5 and the fastening bolt 6. Then the staff can push the fixed engine 4 to move to the support plate 15 of the test room through the auxiliary bracket body 1, and under the guidance of the guide groove 17, the rotating wheel of the auxiliary bracket body 1 enters the interior of the limiting groove 16 to position the auxiliary bracket body 1. At this time, the staff can rotate the engine 4, so that the engine 4 drives the support frame 3 to rotate through the fixing member 5, and then the support frame 3 drives the stepped rotating wheel 2 to rotate along the inside of the auxiliary bracket body 1. The rotation of the support frame 3 will squeeze the pressing piece 7 to descend, so that the pressing piece 7 drives the telescopic rotating piece 8 to rotate and squeezes the clamping rod 13 to slide. The rotation of the telescopic rotating piece 8 will drive the connecting block 9 to slide up along the outer wall of the limiting rod 11 and push the spring 10 to contract, and the sliding of the clamping rod 13 will squeeze the elastic piece 14 to contract and insert the support The position of the auxiliary bracket body 1 is limited and fixed inside the plate 15 to prevent the auxiliary bracket body 1 from being displaced during the test, which affects the accuracy of the vibration test of the support frame 3. When the support frame 3 is driven to rotate ninety degrees, the support frame 3 will stop limiting the block 12, so that the block 12 is partially separated from the inside of the auxiliary bracket body 1 under the push of the spring 10, and the support frame 3 is limited and fixed, so that the block 12 pulls the connecting piece 19 to insert into the slot 18 of the step wheel 2, and further limit and fix it through the step wheel 2, so as to achieve the effect of quickly fixing and limiting the engine 4, so that the auxiliary bracket can assist the staff to fix the engine 4, so as to improve the efficiency of the staff to fix the engine 4 and reduce the required process, which is convenient for the staff to use. At this time, the engine 4 is installed and fixed inside the test room, and the staff can connect and fix the components required for the test, and then control the engine 4 to work and test the vibration of the engine 4 at different speeds;
[0025] Furthermore, when the staff has completed the vibration test of the engine 4, the components required for the test can be removed, and then the staff can press the connecting piece 19 exposed from the top of the auxiliary bracket body 1, so that the connecting piece 19 is disengaged from the inside of the card slot 18 and drives the card block 12 to move and reset, so that the card block 12 squeezes the spring 10 to shrink and enter the inside of the auxiliary bracket body 1 to stop limiting the support frame 3, so that the staff can rotate the engine 4 to reset, and let the engine 4 drive the support frame 3 and the stepped wheel 2 to rotate and reset through the fixing member 5. At this time, the support frame 3 stops squeezing the pressure piece 7, and the spring 10 can push the connecting block 9 to reset, so that the connecting block 9 pushes the pressure piece 7 to reset through the telescopic rotating member 8, and the resetting of the pressure piece 7 will stop squeezing the card rod 13, so that the elastic member 14 can push the card rod 13 back to the inside of the auxiliary bracket body 1, and then the staff can pull the auxiliary bracket body 1 out of the limiting groove 16 of the support plate 15, and transport the tested engine 4 away, so as to facilitate the staff to transport the tested engine 4 away, and facilitate the use of the staff.
