Technical Field

[0001] This utility model relates to the technical field of balance shafts, and in particular to a balance shaft assembly anti-loosening detection device. Background Technology

[0002] The balance shaft is a key auxiliary component in the engine used to counteract vibration and improve the smoothness of operation. Its core principle is to generate a reverse centrifugal force through its own rotation to neutralize the inertial vibration generated when the engine is working. Before use, the balance shaft must undergo an anti-loosening test to ensure that it can be used normally.

[0003] When using anti-loosening detection devices to inspect balance shafts, traditional devices can mostly only test a single specification of balance shaft to ensure its normal use. Currently, the common method is to change the testing equipment to test different balance shafts. However, while changing the testing equipment allows for the testing of balance shafts of different specifications, it requires a significant amount of time to find a testing device suitable for that specification, thus affecting the testing efficiency of balance shafts.

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] The following describes an embodiment of the present invention with reference to the accompanying drawings: a balance shaft assembly anti-loosening detection device.

[0022] like Figures 1-4 As shown in the figure, a balance shaft assembly anti-loosening detection device according to an embodiment of the present invention includes: a body 1 and an adjustment mechanism 3.

[0023] The adjustment mechanism 3 includes a telescopic plate 31, a fixed shell 32, a connecting column 33, a connecting seat 35, a slide rail 37, a telescopic column 38, a fixing component 39, a telescopic rod 310, a fixing ring 311, and a second spring 312.

[0024] The telescopic plate 31 is mounted on the body 1, the fixed shell 32 is mounted on the telescopic plate 31, the connecting columns 33 are symmetrically arranged on the outer wall of the fixed shell 32, the outer wall of the body 1 has a connecting groove 34, the connecting seat 35 is mounted in the connecting groove 34, the inner wall of the connecting groove 34 has a first sliding groove 36, the slide rail 37 is mounted on the outer wall of the connecting seat 35, the telescopic column 38 is mounted on the connecting seat 35, and the other end of the telescopic column 38 is connected to the fixed shell 32, the fixing component 39 is mounted on the connecting column 33, the telescopic rod 310 is mounted in the fixed shell 32, the fixing ring 311 is connected to the other end of the telescopic rod 310, the second spring 312 is sleeved on the outside of the telescopic rod 310, and the two ends of the second spring 312 are respectively connected to the inner wall of the fixed shell 32 and the outer wall of the fixing ring 311. The fixing ring 311 is provided with a pulley 313.

[0025] Specifically, when using the testing device body 1 to perform assembly testing on the balance shaft, the fixed housing 32 is pulled upward or downward and pulled outward according to the size of the balance shaft to be tested. The fixed housing 32 drives the connecting seat 35 to move outward together through the telescopic column 38, thereby ensuring that the fixed housing 32 can move outward horizontally. Then, the balance shaft is fixed on the body 1 and closed to the fixed housing 32. The fixing ring 311 inside the fixed housing 32 will contact the support of the balance shaft and fix it. Then, the body 1 is started to start the anti-loosening test of the balance shaft.

[0026] In one embodiment of this application, such as Figure 3 As shown, the fixing component 39 includes a first spring 394 and a first latch 395.

[0027] The outer wall of the fixed shell 32 is provided with a second sliding groove 391, the inner wall of the second sliding groove 391 is provided with a first limiting groove 392, the outer wall of the connecting column 33 is provided with a first mounting hole 393, the first spring 394 is disposed in the first mounting hole 393, and the first latch 395 is connected to the other end of the first spring 394.

[0028] Specifically, when it is necessary to close the fixed shell 32, press the first latch 395 so that the first latch 395 retracts into the first mounting hole 393, and then push the fixed shell 32 so that the distance between the two pairs of fixed shells 32 can fix the balance shaft. When the appropriate distance is determined, the first latch 395 can be released to complete the fixation.

[0029] In one embodiment of this application, such as Figure 4 As shown, a base 2 is provided at the bottom of the body 1.

[0030] The base 2 is equipped with a protective mechanism 4.

[0031] The protective mechanism 4 includes a mounting frame 41, a cover plate 42, an extension seat 43, a second latch 45, and a third spring 46.

[0032] The mounting frame 41 is mounted on the base 2, the cover plate 42 is pivotally connected to the mounting frame 41, the extension seat 43 is mounted on the outer wall of the cover plate 42, the extension seat 43 is provided with a second mounting hole 44, the second latch 45 is provided in the second mounting hole 44, the third spring 46 is provided in the second mounting hole 44, and the other end of the third spring 46 is connected to the second latch 45. The base 2 is provided with a second limiting groove 47.

[0033] It should be noted that the mounting frame 41 and cover plate 42 described in this embodiment are made of glass. Their main function is to allow the balance shaft to be observed through the mounting frame 41 and cover plate 42 during testing.

[0034] Specifically, when performing anti-loosening tests on the balance shaft, the balance shaft is fixed on the machine body 1, and then the cover plate 42 is closed, so that the second latch 45 is engaged in the second limiting groove 47 on the base 2, and then the test is started. At this time, the mounting frame 41 and the cover plate 42 prevent the balance shaft from becoming loose, which could cause parts to fly out and injure the test personnel.

[0035] Working principle: When using the testing device body 1 to assemble and test the balance shaft, depending on the size of the balance shaft to be tested, the fixing housing 32 is pulled upwards or downwards and pulled outwards. The fixing housing 32, through the telescopic column 38, drives the connecting seat 35 to move outwards together, thereby ensuring that the fixing housing 32 can move outwards horizontally. Then, the balance shaft is fixed on the body 1 and the fixing housing 32 is closed. The fixing ring 311 inside the fixing housing 32 will contact and fix the balance shaft's support. Then, the body 1 is started to perform anti-loosening testing on the balance shaft. When it is necessary to close the fixing housing 32, at this time... Press the first latch 395 to retract it into the first mounting hole 393, and then push the fixing shell 32 so that the distance between the two pairs of fixing shells 32 can fix the balance shaft. When the appropriate distance is determined, the first latch 395 can be released to complete the fixation. When the balance shaft is checked for loosening, the balance shaft is fixed on the machine body 1, and then the cover plate 42 is closed, so that the second latch 45 is engaged in the second limiting groove 47 on the base 2. Then the test begins. At this time, the mounting frame 41 and the cover plate 42 prevent the balance shaft from loosening, which could cause parts to fly out and injure the test personnel.
