[0031] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0032] The embodiments of the present application are further described below in detail with reference to the drawings.

[0033] The embodiments of the present application provide a detection device for the bonding quality of a bonding agent of a motor train unit window, which detects the bonding quality of the bonding agent according to the actual detection requirement of the bonding of a train, and effectively improves the efficiency of the detection equipment in the measuring process.

[0034] In order to achieve the above technical effects, the general idea of the present application is as follows:

[0035] A detection device for the bonding quality of a bonding agent of a motor train unit window, comprising:

[0036] A support seat 1, a working cavity 10 is arranged at the bottom center of the support seat 1;

[0037] A rotating handle 2 arranged on the top surface of the support seat 1;

[0038] A pressure gauge 3 arranged on the top surface of the rotating handle 2;

[0039] A test probe 4 arranged at the bottom of the support seat 1 and located in the working cavity 10; wherein,

[0040] The test probe 4 is internally transmissionally connected with the pressure gauge 3;

[0041] The rotating handle 2 is configured to drive the pressure gauge 3 and the test probe 4 to move up and down in the height direction of the support seat 1.

[0042] The embodiments of the present application are further described below in detail with reference to the drawings.

[0043] Referring to Figs. 1-2 The present application provides a detection device for the bonding quality of a bonding agent of a motor train unit window, comprising:

[0044] A support seat 1, a working cavity 10 is arranged at the bottom center of the support seat 1;

[0045] A rotating handle 2 arranged on the top surface of the support seat 1;

[0046] a pressure gauge 3 arranged on the top surface of the rotating handle 2;

[0047] a test probe 4 arranged on the bottom of the support base 1 and located in the working cavity 10; wherein,

[0048] the test probe 4 is internally transmissionally connected with the pressure gauge 3;

[0049] the rotating handle 2 is configured to drive the pressure gauge 3 and the test probe 4 to move up and down in the height direction of the support base 1.

[0050] It should be noted that the technical scheme of the embodiment of the present application is simple in structure, convenient and quick to operate. After the operation of the existing EMU window glass adhesive is completed, it is difficult to test whether the interior is full of adhesive and whether there are air bubbles, etc. The naked eye cannot be observed, and it is difficult to compare the sound measurement by knocking. It is relatively easy to use destructive testing methods, but it is not suitable for on-site inspection.

[0051] The technical scheme of the embodiment of the present application is tested in advance for each type of bonding joint. Different values are tested for joints of different qualities. The detection equipment is adjusted according to these test data, so that the equipment displays corresponding pressure under corresponding stroke. If the corresponding stroke and the displayed pressure value are different, and the value exceeds a certain difference, it indicates that the internal adhesive quality has a problem. The position of the adhesive quality defect can be quickly and simply found out.

[0052] In the embodiment of the present application, the adhesive bonding quality detection is carried out according to the actual detection requirements of the bonding of the train, which effectively improves the efficiency of the detection equipment in the measurement process.

[0053] Further, the support base 1 comprises:

[0054] a base body 11;

[0055] at least two base feet 12 uniformly distributed on the bottom surface of the base body 11;

[0056] the working cavity 10 is formed between the base body 11 and each base foot 12.

[0057] Further, the pressure gauge 3 comprises:

[0058] a pressure gauge body 30;

[0059] a pressure gauge base 31 arranged on the bottom of the pressure gauge body 30, and a probe mounting cavity 310 is arranged in the pressure gauge base 31;

[0060] The top of the test probe 4 is arranged in the probe mounting cavity 310 and is in transmission connection with the inside of the pressure gauge body 30; wherein,

[0061] The pressure gauge base 31 is arranged in the rotating handle 2;

[0062] The rotating handle 2 is configured to drive the pressure gauge base 31 to move up and down in the height direction of the support seat 1, so as to drive the pressure gauge body 30 and the test probe 4 to move synchronously in the support seat 1.

[0063] The technical scheme of the embodiment of the application has the following technical points in specific implementation:

[0064] The support seat 1 of a specified detection device is mainly composed of an aluminum alloy structure with a hardness greater than that of an adhesive after solidification, and the bottom is a circular arc. The circular arc bottom is covered with plastic in the part in contact with the surface of the vehicle. The circular arc is used to adapt to the shapes of the outer surfaces of various vehicle bodies, and the plastic covering prevents damage to the paint of the vehicle. When in use, the support seat 1 is placed on both sides of the rubber joint, and the pressure gauge body 30 is adjusted to be perpendicular to the rubber joint as much as possible by the cylindrical contact surface, and the plastic covering prevents damage to the paint on the surface of the vehicle body.

[0065] The upper end of the support seat 1 is provided with a threaded inner hole, which is used to move the pressure gauge body 30 and the pressure gauge base 31 up and down when the rotating handle 2 is shaken.

[0066] The upper end of the support seat 1 is provided with a scale on the outside, and the circumference is 360 degrees.

[0067] Furthermore, the pressure gauge body 30 and the pressure gauge base 31 can rotate freely, but the up-and-down movement is limited, and the pressure gauge body 30 moves up and down together with the pressure gauge base 31;

[0068] The outer part of the ground section of the pressure gauge base 31 is externally threaded and matched with the central threaded hole of the support seat 1.

[0069] If necessary, the rotating handle 2 and the pressure gauge base 31 can be welded together to form one component in structure, and the pressure gauge base 31 rotates with the rotating handle 2;

[0070] The non-threaded part of the upper part of the pressure gauge base 31 is provided with a downward arrow, which corresponds to the scale of the support seat 1, and the rotation degree of the rotating handle 2 can be accurately recorded.

[0071] In use, the pressure gauge body 30 moves downward with the pressure gauge base 31, the internal test probe 4 abuts against the cured adhesive surface, and the pressure gauge body 30 moves downward with the rotation of the handle 2, the test probe 4 is subjected to an increased force, the reading of the pressure gauge body 30 changes, and the value of the pressure gauge body 30 is read after reaching the specified stroke. Whether it is normal or not is determined according to the correct data obtained in the preliminary test.

[0072] If necessary, the position of the test probe 4 and the rotating stroke are adjusted in advance according to the laboratory data of different adhesive joints, and the data values of each position and each measuring point are recorded and compared with the test data to determine whether the adhesive quality meets the requirements through the difference.

[0073] In summary, the technical scheme of the embodiment of the application has simple structure, low cost, and strong practicability, and can effectively and intuitively obtain a conclusion in real time.
