[0042] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

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

[0044] The inspection tool 2 includes a mounting seat 21, a flip platform 22, a support platform 23 and a clamping assembly 24; the flip platform 22 is rotatably mounted between the mounting seats 21, and the rotating shaft of the flip platform 22 extends horizontally; the support platform 23 and the clamping assembly 24 are both mounted on the top of the flip 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 inspected, 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, wherein the mounting plate 232 is closely attached to 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 both extend vertically through the interior of the channel plate 231, and the first detection channel 233 and the second detection channel 234 are both used to accommodate the detection bead 237; the first detector 235 and the second detector 236 are embedded and installed in the interior of the mounting plate 232, and the detection ends of the first detector 235 and the second detector 236 are both flush with the upper surface of the mounting plate 232;

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

[0047] The shape of 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 the prior art, the method for detecting whether the oil passage of the transmission cover of an automobile engine is blocked is generally for the inspector to manually insert an endoscope into the oil passage and directly observe the situation inside the oil passage to make a judgment. Therefore, there is a risk of missed detection or wrong detection.

[0050] Therefore, in order to realize the automatic inspection of oil passage blockage and solve the technical problem that the existing manual inspection is prone to missed inspection and wrong inspection, this technical solution proposes a detection device for oil passage blockage of automobile engine transmission cover, such as Figure 1-4As shown, it includes a detection platform 1 and a detection tool 2.

[0051] Among them, the detection tool 2 is used to install the transmission cover 3 to be detected. When using the detection equipment of this scheme to detect whether the oil channel of the transmission cover 3 is blocked, the transmission cover 3 is first pressed to the plane of the support platform 23 by using the clamping assembly 24, and the upper port of the first detection channel 233 is connected to the first opening of the oil channel 31 of the transmission cover 3 to be detected, and the upper port of the second detection channel 234 is connected to the second opening of the oil channel 31 of the transmission cover 3 to be detected. A detection bead 237 is placed in the first detection channel 233 or the second detection channel 234, and driven by the flip platform 22, the first detector 235 and the second detector 236 detect the detection bead 237 to determine whether the detection bead 237 can pass through the oil channel 31, so as to determine whether the oil channel 31 is blocked. Compared with the detection method in which the detection personnel manually insert an endoscope into the oil channel 31 and directly observe the situation inside the oil channel 31 for judgment, the detection equipment of this scheme only needs to make judgments 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 detection and wrong detection.

[0052] It should be noted that the "blockage" of the oil passage 31 in the present solution generally refers to the situation where brushes or bumps appear on the inner wall of the oil passage 31, resulting in the detection beads 237 being unable to pass smoothly.

[0053] To further explain, the inspection tool 2 also includes a positioning round pin 25, which is installed on the top of the flip platform 22, and the top end of the positioning round pin 25 is used to be accommodated in the interior of the positioning hole of the gearbox cover 3 to be inspected.

[0054] In a preferred embodiment of the present technical solution, the detection tool 2 also includes a positioning round pin 25, which is helpful to improve the installation stability of the gearbox cover 3 to be detected on the detection tool 2 and avoid horizontal displacement during rotation.

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

[0056] In another preferred embodiment of the present technical solution, at least three groups of clamping assemblies 24 are provided to more effectively clamp the gearbox cover 3 to be inspected against the support platform 23. On the one hand, it can effectively prevent horizontal displacement during rotation, resulting in the upper port of the first detection channel 233 not corresponding to the first opening of the oil channel 31 of the gearbox cover 3 to be inspected, and the upper port of the second detection channel 234 not corresponding to the second opening of the oil channel 31 of the gearbox cover 3 to be inspected, thereby affecting the detection result. On the other hand, it is helpful to prevent the detection bead 237 from detaching from the first detection channel 233, the second detection channel 234 or the oil channel 31 during the detection process.

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

[0058] The pressing cylinder 241 is installed on the top of the turning platform 22, and the output shaft of the pressing cylinder 241 is located on the top of the pressing cylinder 241;

[0059] The mounting bracket 242 is mounted on the top edge of the pressing cylinder 241, the middle portion of the pressing arm 243 is hinged to the top of the mounting bracket 242, and the pressing arm 243 is swingably mounted on the top of the pressing 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 clamping arm 243 to swing.

[0061] Specifically, the present solution realizes the swinging of the clamping arm 243 by means of a lever, which is conducive to realizing that the other end of the clamping arm 243 acts on the gearbox cover 3 and presses it against the surface of the support platform 23 .

[0062] It is further explained that the number of the detection components matches the number of the oil passages 31 of the transmission cover 3 to be detected, and one detection component corresponds to one oil passage 31 .

[0063] In a more preferred embodiment of the present technical solution, the number of detection components can be matched with the number of oil channels 31 of the transmission cover 3 to be detected, so that the blockage conditions of all oil channels 31 (generally 5) of the transmission cover 3 can be detected at one time, which is beneficial to improving the detection efficiency of the detection equipment.

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

[0065] To further explain, the inspection tool 2 further includes a servo motor 26 , the output shaft of the servo motor 26 is connected to one end of the rotating shaft of the flip platform 22 , and the servo motor 26 is used to drive the flip platform 22 to rotate.

[0066] A method for detecting the blockage of an oil passage of a vehicle engine transmission cover, using the above-mentioned detection device for the blockage of an oil passage of a vehicle engine transmission cover, comprises the following steps:

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

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

[0069] C. Using the pressing assembly 24 to press the gearbox cover 3 onto the surface of the support platform 23;

[0070] D. Flip the flip platform 22 360°;

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

[0072] Otherwise it will be blocked.

[0073] This technical solution also proposes a detection method using the above-mentioned automobile engine transmission cover oil channel blockage detection device, and its principle schematic diagram is shown as follows: Figure 5 As shown, driven by the flip platform 22, the detection bead 237 passes through the first detection channel 233 and the oil channel 31 in sequence under the action of gravity, and then enters the second detection channel 234, and is detected by the second detector 236 located at the bottom of the second detection channel 234 to determine whether the detection bead 237 is in place, so as to determine whether the oil channel 31 it passes through is blocked. The steps are simple and the operability is strong, which can effectively improve the detection efficiency of the blockage of the oil channel of the automobile engine transmission cover.

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

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

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

[0077] Otherwise it will be blocked.

[0078] As a preference of the above embodiment, the detection method of the present solution may also be performed in step D by repeatedly passing through the oil passage 31 of the gearbox cover 3 to be detected, so as to ensure the validity and accuracy of the detection result.
