Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting inspection tools, in particular to a pipe fitting inspection tool for automobile parts. Background Art

[0002] Automotive parts pipe fittings are an important component of the car, used to connect and transmit liquids or gases, including hydraulic pipe fittings, air pipe fittings, etc. Therefore, after the pipe fittings are produced, they need to be inspected. The inspection is carried out by using a testing fixture, which consists of a testing seat and a testing slot. During the inspection, the pipe fitting is placed in the testing slot and fixed by a clamp. Then, its size is inspected with a feeler gauge to check whether the outer diameter of the pipe fitting is qualified. Secondly, the personnel also need to squat and observe the pipe fitting from four directions: front, back, left and right. The bulges and depressions of the pipe fitting are judged by experience to prevent the existence of large bulges and depressions in the pipe fitting.

[0003] When inspecting the bulges and depressions of pipe fittings, it is necessary to inspect the bulges and depressions of the pipe fittings from multiple directions. The inspection takes a long time and has low inspection efficiency. Therefore, the present application provides an automotive parts pipe inspection tool to meet the needs. Utility Model Content

One end of the detection head 411 is in contact with the side of the middle contact block 412, and the detection seat 2 is inlaid with a battery 401 in the direction away from the detection slot 3. The LED lamp 1 402, LED lamp 2 403 and LED lamp 3 404 are fixed on the top, the battery 401 is electrically connected to the detection head 411, the LED lamp 1 402, LED lamp 2 403 and LED lamp 3 404 are electrically connected to the upper contact block 413, the middle contact block 412 and the lower contact block 414 respectively, the battery 401 is electrically connected to the LED lamp 1 402, LED lamp 2 403 and the LED lamp, the upper contact block 413 and the lower contact block 414 are both resistor blocks, and the detection When the measuring block 407 slides, the contact position between the detection head 411 and the upper contact block 413 or the lower contact block 414 changes, the resistance value of the circuit where the upper contact block 413 or the lower contact block 414 is located changes, and the brightness of the LED lamp 402 or the LED lamp 3 404 changes from bright to dark. The detection seat 2 is an injection molded part with non-conductive properties. The LED lamp 1 402 is electrically connected to the top position of the upper contact block 413, and the LED lamp 3 404 is electrically connected to the bottom position of the lower contact block 414.

[0030] like Figure 2 As shown, in this embodiment, the top of the detection block 407 is a downward curved surface, which is used to make the top of the detection block 407 fit more closely to the surface of the pipe fitting and make the measurement more accurate.

[0031] like Figure 2 As shown, in this embodiment, a rubber pad 408 is fixed in the curved surface on the top of the detection block 407. The rubber pad 408 is made of hard rubber and protects the pipe fitting to avoid damage to the pipe fitting.

[0032] like Figure 3 As shown, in this embodiment, the detection block 407 is a plastic block to prevent the detection block 407 from being conductive and improve detection accuracy.

[0033] like Figure 2 As shown, in this embodiment, the elastic force of the vertical spring 406 is greater than the gravity of the detection block 407 , so that the vertical spring 406 provides stable support for the detection block 407 .

[0034] like Figure 3 As shown, in this embodiment, a slope is provided on one side of the detection head 411 close to the detection block 407 to shorten the contact area between the detection head 411 and the contact surface, thereby making the detection more accurate.

[0036] like Figure 3 As shown, in this embodiment, the middle contact block 412 is a copper block, which is used to reduce the resistance value of the circuit in which the middle contact block 412 is located, thereby reducing power consumption.

[0037] Working principle: place the support plate 1 on the desktop, put the pipe into the detection groove 3 of the detection seat 2, and fix the pipe with a clamp. After the pipe is placed in the measuring groove, the pipe fits with the rubber pad 408, and the pipe drives the rubber pad 408 to move downward, and the rubber pad 408 drives the detection block 407 to move downward. At this time, the vertical spring 406 in the vertical groove 405 is compressed; when the size of the pipe is standard and there is no upward or downward bending, the horizontal spring 410 in the horizontal groove 409 drives the detection head 411 to fit the side of the middle contact block 412, and the LED light 2 403, the battery 401 and the middle contact block 412 form a closed circuit. At this time, the LED light 2 403 lights up, indicating that the pipe is normal; when the pipe bulges upward, the detection head 411 contacts the lower contact block 414, and the LED light 3 404, the battery 401 and the lower contact block 414 form a closed circuit. The LED light 3 404 lights up, indicating that the LED light 3 40 4 The pipe fitting at the illuminated portion is bent upward, and the greater the degree of upward bending of the LED light 3 404, the closer the detection head 411 contacts the lower contact block 414 to the bottom. As the contact moves downward below the contact block 414, the resistance value in this circuit decreases, and the LED light 3 404 becomes brighter, indicating that the pipe fitting is bent upward to a greater extent. When the pipe fitting is bent downward, the detection head 411 contacts the upper contact block 413, and the LED light 1 402, the battery 401 and the upper contact block 413 form a closed circuit. The LED light 1 402 lights up, indicating that the pipe fitting at the illuminated portion of the LED light 1 402 is bent downward. As the degree of downward bending of the pipe fitting is greater, the detection head 411 contacts the upper position of the upper contact block 413, the resistance value in this circuit decreases, and the LED light 1 402 becomes brighter, indicating that the degree of downward bending of the pipe fitting is greater. After the bending portion of the pipe fitting is inspected, the fixture is removed and the pipe fitting can be taken off.

To provide a thorough understanding of the present invention, specific details are described in detail in the preferred embodiments of the present invention above, but those skilled in the art can fully understand the present invention without these detailed descriptions.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
