[0001] The utility model relates to the technical field of crawler chassis testing, in particular to a convenient testing device for the sealing performance of a crawler chassis bracket. Background Art

[0002] The crawler chassis bracket is used to connect the crawler drive wheel. A certain amount of lubricating oil needs to be injected into the inside of the wheel, so it needs to be sealed without oil leakage. Therefore, it is necessary to test the sealing of the crawler chassis bracket. In the prior art, a handheld ram is used to press down to perform an air injection test. Such a test structure has low efficiency, high labor intensity and low accuracy. Utility Model Content

[0003] Therefore, the purpose of the utility model is to provide a convenient testing device for the sealing performance of a crawler chassis bracket. Through the mutual cooperation of the set test support assembly and the sealing test assembly, when in use, the air nozzle head can be pushed down for testing by directly pulling the operating lever.

[0025] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] The utility model provides a convenient testing device for the sealing performance of a crawler chassis bracket. Through the cooperation of a test support component and a sealing test component, when in use, the air nozzle head can be driven to press down for testing simply by pulling an operating lever. The utility model utilizes the principle of a lever, is labor-saving, simple to operate, and has high accuracy and efficiency.

[0027] Figure 1-Figure 3 The figure shows the overall structure of a convenient test device for the sealing performance of a crawler chassis support of the utility model. Figure 1-Figure 3The main structure of this embodiment includes: a test support component and a sealing test component.

[0028] The test support assembly is used in conjunction with the sealing test assembly. Specifically, the test support assembly includes a support base plate 11, a vertical plate support frame 12 fixed to the top of the support base plate 11, a notch groove 13 provided on the top surface of the vertical plate support frame 12, an operating rod 14 inserted into the notch groove 13, a rotating shaft 15 passing through the vertical plate support frame 12 and the operating rod 14, and a support plate 16 provided on the top surface of the support base plate 11. The test support assembly also includes a crawler chassis support body 17 sleeved with the support plate 16 and an oil filling hole 18 provided on the top of the crawler chassis support body 17.

[0029] During specific use, the sealing test assembly is installed and used based on the bracket base plate 11, the vertical plate support frame 12, the notch groove 13, the operating rod 14, the rotating shaft 15 and the support plate 16 to complete the airtightness test.

[0030] The sealing test assembly is used to simplify the operation and improve the test efficiency. Specifically, the sealing test assembly includes an air filling tank 21 arranged on the top surface of the bracket bottom plate 11, a pressure gauge 22 connected to the air filling tank 21, an air intake pipe 23 connected to the air filling tank 21, a mounting plate 25 arranged on the side wall of the operating rod 14, and a gas nozzle head 24 penetrating the mounting plate 25 and connected to the mounting plate 25;

[0031] During specific use, the user fits the crawler chassis bracket body 17 onto the side of the mounting plate 25. At this time, the user pulls the operating lever 14 downward, and the operating lever 14 rotates through the rotating shaft 15. The operating lever 14 directly drives the air nozzle head 24 to move downward and directly supports the oil filling hole 18. At this time, the control valve of the inflation tank 21 is opened to start inflation. After inflation, the control valve is closed, and the value of the pressure gauge 22 is observed. Observe whether the needle of the pressure gauge 22 moves to the right. If the needle does not move, it is qualified, otherwise it moves, it is unqualified. After the time is up, release the operating lever 14 and lift it upward to complete the test.

[0032] Furthermore, the indicating component is provided to indicate the landing point of the gas nozzle head 24 during the process of pressing down the gas nozzle head 24, so as to avoid the gas nozzle head 24 deviating from and hitting the workpiece when the operator pulls the operating lever 14 to press down, causing the gas nozzle to bend;

[0033] Specifically, it also includes an indicator assembly, which includes a first annular plate 31 fixed on the surface of the gas nozzle head 24, a second annular plate 32 arranged directly opposite to the first annular plate 31, and a spring 33 connected to the bottom surface of the first annular plate 31. The indicator assembly also includes a circular hole 34 opened on the surface of the second annular plate 32 and an indicator rod 35 passing through the circular hole 34;

[0034] When the air nozzle top 24 moves downward, the indicator rod 35 is located at the front end of the air nozzle top 24, and the annular indicator rod 35 contacts the crawler chassis bracket body 17 before the air nozzle top 24. The middle position of the indicator rod 35 distributed at three points is the landing point of the air nozzle top 24. If the middle position of the indicator rod 35 distributed at three points is not the position of the oil filling hole 18, it means that there is an error, and the operator stops pressing the operating rod 14 in time. If the middle position of the indicator rod 35 distributed at three points is the position of the oil filling hole 18, the operating rod 14 continues to be pressed down at this time. When the indicator rod 35 contacts the crawler chassis bracket body 17 and continues to be subjected to pressure, the spring 33 is compressed so that the air nozzle top 24 can be accurately pressed in. When the test is completed and the air nozzle top 24 moves upward, the spring 33 recovers its deformation for the next test.

[0035] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
