Description

Technical Field

[0001] The utility model relates to the technical field of exhaust pipe lifting lug stiffness measurement, in particular to exhaust pipe lifting lug stiffness measurement equipment. Background Art

[0002] The exhaust pipe lifting lug is a component in the automobile exhaust system, which is used to fix the exhaust pipe and reduce vibration noise. Usually, the lifting lug can firmly fix the exhaust pipe to the automobile chassis to ensure that the exhaust pipe will not be displaced or fall off due to vibration during driving. If the lifting lug is damaged or worn, it will affect the fixing effect of the exhaust pipe.

[0003] Therefore, it is necessary to ensure the quality of the exhaust pipe lifting lug and test the stiffness of the lifting lug through a lifting lug stiffness testing device. For example, in the patent document with application number 201721319690.2, an exhaust pipe lifting lug stiffness measuring device is disclosed, and it is specifically disclosed that the multi-directional clamping of the facility is used to ensure the stability of the clamping, and the automatic detection device is used to detect it.

[0004] When the exhaust pipe lifting ear is in use, the side of the exhaust pipe lifting ear needs to be tested for rigidity, that is, it is necessary to test how much external force the exhaust pipe lifting ear is subjected to before squeezing the exhaust pipe, thereby causing deformation of the exhaust pipe. However, when conventional equipment performs rigidity tests on the lifting ear, firstly, the force is applied in the wrong direction, and the maximum force that the lifting ear can withstand when it is squeezed on the side cannot be tested; secondly, a groove for installing the exhaust pipe is opened in the middle of the lifting ear, and the exhaust pipe itself has a certain hardness. The rigidity of the exhaust pipe has a certain influence on the side rigidity of the lifting ear. If it is detached from the exhaust pipe during the test, the test result will be affected. Utility Model Content

[0005] The technical problem solved by the utility model is to solve the problem in the prior art that when the rigidity of the exhaust pipe lifting lug is tested, the through groove in the middle of the lifting lug has no support from the exhaust pipe, resulting in inconsistency between the relative rigidity and that in actual work.

[0006] The utility model can be implemented through the following technical scheme: an exhaust pipe lifting ear stiffness measuring device comprises a base for placing a lifting ear body, and the base is provided with a sample tube for supporting the center of the lifting ear body through a longitudinal moving device.

[0007] A further technical improvement of the utility model is that the longitudinal moving device comprises a top telescopic rod, and the sample tube is mounted on the output end of the top telescopic rod through a detachable mechanism.

[0008] A further technical improvement of the utility model is that the detachable mechanism comprises a mounting base, the mounting base is fixed to the output end of the top telescopic rod, a sample connecting plate is fixed to the end of the sample tube, and the mounting base and the sample connecting plate are connected by bolts.

[0009] A further technical improvement of the utility model is that a limiting column for cooperating with the side of the lifting ear body is fixed on the base, and a limiting bottom plate for supporting the lifting ear body is arranged on the limiting column.

[0010] A further technical improvement of the utility model is that a threaded portion is provided on the limiting column, and the threaded portion is threadedly connected to a detachable limiting top plate.

[0011] A further technical improvement of the utility model is that: a plurality of groups of test telescopic rods are fixed on the base, and the output ends of the test telescopic rods are provided with test clamping plates for supporting the lifting ear body.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The present application adopts a sample tube, so that when the stiffness of the lifting ear body is tested, the sample tube is moved into the groove by a longitudinal moving device to support the pipe mounting hole in the middle of the lifting ear body. Therefore, during the testing of the lifting ear body, the sample tube is used to simulate the exhaust pipe entering the lifting ear body to simulate the state of the lifting ear body when in use, thereby obtaining a lifting ear stiffness result with higher accuracy.

[0014] 2. The present application adopts the use of limit columns so that the side mounting holes on the lifting ear body are inserted into the limit columns, the lifting ear body is supported by a limit bottom plate, and the lifting ear body is fixed by a detachable limit top plate, thereby achieving further limiting effect on the lifting ear body, thereby ensuring the stable position of the lifting ear body during the rigidity test.

[0015] 3. The present application adopts a test telescopic rod, so that when the test telescopic rod is started to drive the test clamping plate to move to the lifting ear body, the test clamping plate is used to further limit the position of the lifting ear body, and at the same time, the test clamping plate is pressed tightly to realize the detection of the rigidity of the lifting ear body, thereby obtaining the rigidity test result of the lifting ear body.
