A detection device and method for oil passage blockage in automobile engine transmission cover

Abstract

This invention discloses a detection device and method for oil passage blockage in automotive engine transmission covers. A clamping assembly presses the transmission cover firmly against a support platform, connecting the upper port of a first detection channel to the first opening of the oil passage in the transmission cover to be tested, and the upper port of a second detection channel to the second opening of the oil passage in the transmission cover to be tested. A detection bead is placed in either the first or second detection channel. Driven by a flipping platform, the placement of the detection bead is determined by the position of a first and second detector to assess whether the bead can pass through the oil passage, thus determining whether the oil passage is blocked. Compared to the traditional method where inspectors manually insert an endoscope into the oil passage to directly observe its internal condition, this detection device only needs to rely on the results of the first and second detectors to make a judgment, making it more automated and effectively avoiding missed or incorrect detections.

[0041] 3. Gearbox cover; 31. Oil passage. Detailed Implementation

[0042] Embodiments of the present invention 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 are only used to explain the present invention, and should not be construed as limiting the present invention.

[0043] This technical solution provides a detection device for oil passage blockage in the transmission cover of an automobile engine, including a detection platform 1 and a detection fixture 2, wherein the detection fixture 2 is installed inside the detection platform 1;

[0044] The testing fixture 2 includes a mounting base 21, a tilting platform 22, a support platform 23, and a clamping assembly 24. The tilting platform 22 is rotatably mounted between the mounting bases 21, and the pivot of the tilting platform 22 extends horizontally. The support platform 23 and the clamping assembly 24 are both mounted on the top of the tilting platform 22, and the clamping assembly 24 is located at the edge of the support platform 23. The support platform 23 is used to place the gearbox cover 3 to be tested, and the clamping assembly 24 is used to press the gearbox cover 3 against the surface of the support platform 23.

[0045] The support platform 23 includes a channel plate 231, a mounting plate 232, and a detection assembly. The mounting plate 232 is in close contact with the lower surface of the channel plate 231. The detection assembly includes a first detection channel 233, a second detection channel 234, a first detector 235, a second detector 236, and a detection bead 237. The first detection channel 233 and the second detection channel 234 extend vertically through the interior of the channel plate 231, and both the first detection channel 233 and the second detection channel 234 are used to accommodate the detection bead 237. The first detector 235 and the second detector 236 are embedded in the interior of the mounting plate 232, and the detection ends of the first detector 235 and the second detector 236 are flush with the upper surface of the mounting plate 232.

[0046] The upper port of the first detection channel 233 is connected to the first opening of the oil passage 31 of the gearbox cover 3 to be tested, and the detection end of the first detector 235 is directly opposite the lower port of the first detection channel 233; the upper port of the second detection channel 234 is connected to the second opening of the oil passage 31 of the gearbox cover 3 to be tested, and the detection end of the second detector 236 is directly opposite the lower port of the first detection channel 233.

[0047] The oil passage 31 is U-shaped;

[0048] The diameter of the detection bead 237 is smaller than the width of the first detection channel 233 and the second detection channel 234, respectively, and the diameter of the detection bead 237 is smaller than the width of the oil passage 31.

[0049] In existing technologies, the method for detecting whether the oil passages in a car engine transmission cover are blocked generally involves inspectors manually inserting an endoscope into the oil passages to directly observe the internal condition. Therefore, this method is prone to missed or incorrect detections.

[0050] Therefore, in order to automate the inspection of oil passage blockages and solve the technical problems of missed or incorrect detections that are prone to occur in existing manual inspections, this technical solution proposes a detection device for oil passage blockages in automotive engine transmission covers, such as... Figure 1-4As shown, it includes a testing platform 1 and a testing fixture 2.

[0051] Among them, the testing fixture 2 is used to install the gearbox cover 3 to be tested. When testing whether the oil passage of the gearbox cover 3 is blocked using the testing equipment of this solution, the gearbox cover 3 is first pressed against the plane of the support platform 23 by the clamping component 24, and the upper port of the first testing channel 233 is connected to the first opening of the oil passage 31 of the gearbox cover 3 to be tested, and the upper port of the second testing channel 234 is connected to the second opening of the oil passage 31 of the gearbox cover 3 to be tested. A detection bead 237 is placed in the first detection channel 233 or the second detection channel 234. Driven by the flipping platform 22, the first detector 235 and the second detector 236 detect the position of the detection bead 237 to determine whether the detection bead 237 can pass through the oil passage 31, thereby determining whether the oil passage 31 is blocked. Compared with the detection method in which the inspector manually inserts an endoscope into the oil passage 31 to directly observe the internal condition of the oil passage 31, the detection equipment in this solution only needs to make a judgment based on the detection results of the first detector 235 and the second detector 236. The detection method is more automated and can effectively avoid missed detections and false detections.

[0052] It should be noted that in this solution, "blockage" of oil passage 31 refers to a situation where the inner wall of oil passage 31 has bristles or protrusions, which prevents the detection bead 237 from passing through smoothly.

[0053] Furthermore, the inspection fixture 2 also includes a positioning pin 25, which is installed on the top of the flipping platform 22, and the top end of the positioning pin 25 is used to accommodate inside the positioning hole of the gearbox cover 3 to be inspected.

[0054] In a preferred embodiment of this technical solution, the testing fixture 2 further includes a positioning pin 25, which helps to improve the installation stability of the gearbox cover 3 to be tested on the testing fixture 2 and prevents it from shifting horizontally during rotation.

[0055] To further explain, at least three sets of the clamping components 24 are provided, and the three sets of clamping components 24 are evenly arranged on the edge of the support platform 23.

[0056] In another preferred embodiment of this technical solution, the clamping assembly 24 is provided with at least three sets to more effectively clamp the gearbox cover 3 to be tested onto the support platform 23. On the one hand, it can effectively prevent horizontal displacement during rotation, which would cause the upper port of the first detection channel 233 to not correspond to the first opening of the oil passage 31 of the gearbox cover 3 to be tested, and the upper port of the second detection channel 234 to not correspond to the second opening of the oil passage 31 of the gearbox cover 3 to be tested, thus affecting the test results. On the other hand, it helps to prevent the detection bead 237 from detaching from the first detection channel 233, the second detection channel 234, or the oil passage 31 during the test.

[0057] To further explain, the clamping assembly 24 includes a clamping cylinder 241, a mounting bracket 242, and a clamping arm 243;

[0058] The clamping cylinder 241 is mounted on the top of the tilting platform 22, and the output shaft of the clamping cylinder 241 is located at the top of the clamping cylinder 241;

[0059] The mounting bracket 242 is mounted on the top edge of the clamping cylinder 241, the middle part of the clamping arm 243 is hinged to the top of the mounting bracket 242, and the clamping arm 243 is swayably mounted on the top of the clamping cylinder 241 through the mounting bracket 242.

[0060] The output shaft of the clamping cylinder 241 is hinged to one end of the clamping arm 243, and the clamping cylinder 241 is used to drive the swing of the clamping arm 243.

[0061] Specifically, this solution uses a lever to swing the clamping arm 243, which helps to make the other end of the clamping arm 243 act on the gearbox cover 3 and press it against the surface of the support platform 23.

[0062] To further explain, the number of the detection components matches the number of oil passages 31 in the gearbox cover 3 to be detected, and one detection component corresponds to one oil passage 31.

[0063] In a more preferred embodiment of this technical solution, the number of detection components can be matched with the number of oil passages 31 of the gearbox cover 3 to be tested, so that the blockage of all oil passages 31 (generally 5) of the gearbox cover 3 can be detected at one time, which helps to improve the detection efficiency of the detection equipment.

[0064] To further clarify, both the first detector 235 and the second detector 236 are proximity switches.

[0065] Furthermore, the inspection fixture 2 also includes a servo motor 26, the output shaft of which is connected to one end of the rotating shaft of the flipping platform 22, and the servo motor 26 is used to drive the rotation of the flipping platform 22.

[0066] A method for detecting oil passage blockage in a car engine transmission cover, using the aforementioned detection equipment for oil passage blockage in a car engine transmission cover, includes the following steps:

[0067] A. Place the detection bead 237 inside the first detection channel 233;

[0068] B. Install the gearbox cover 3 to be tested on the surface of the support platform 23, and make the upper port of the first detection channel 233 communicate with the first opening of the oil passage 31 of the gearbox cover 3 to be tested, and the upper port of the second detection channel 234 communicate with the second opening of the oil passage 31 of the gearbox cover 3 to be tested.

[0069] C. Use the clamping assembly 24 to press the gearbox cover 3 against the surface of the support platform 23;

[0070] D. Rotate the flipping platform 22 360°;

[0071] If the second detector 236 detects that the detection bead 237 is in place, then the oil passage 31 of the gearbox cover 3 to be tested is not blocked;

[0072] Otherwise, it will cause a blockage.

[0073] This technical solution also proposes a detection method using the aforementioned detection equipment for detecting oil passage blockage in the automotive engine transmission cover, the schematic diagram of which is shown below. Figure 5 As shown, driven by the flipping platform 22, the detection bead 237 passes through the first detection channel 233 and the oil passage 31 in sequence under the action of gravity, and then enters the second detection channel 234. The second detector 236 located at the bottom of the second detection channel 234 detects the position of the detection bead 237, and thus determines whether there is a blockage in the oil passage 31 it passes through. The steps are simple and easy to operate, and can effectively improve the detection efficiency of oil passage blockage in automobile engine transmission cover.

[0074] To further explain, step D also includes:

[0075] D. After flipping the flipping platform 22 360°, flip the flipping platform 22 360° again to reset it;

[0076] If the second detector 236 detects that the detection bead 237 is in place after the flipping platform 22 is flipped 360°, and the first detector 235 detects that the detection bead 237 is in place after the flipping platform 22 is flipped 360° and reset, then the oil passage 31 of the gearbox cover 3 to be tested is not blocked.

[0077] Otherwise, it will cause a blockage.

[0078] As a preferred embodiment of the above, the detection method of this solution can also repeatedly pass through the oil passage 31 of the gearbox cover 3 to be tested in step D to ensure the effectiveness and accuracy of the detection results.
