Description

Technical Field

[0001] This utility model relates to the field of automotive parts assembly technology, and in particular to a self-inspection device for paint markings on automotive cooling system pipe connections. Background Technology

[0002] A car transmission is a gearbox that coordinates the engine speed and the actual speed of the wheels to achieve the best engine performance. It can generate different gear ratios between the engine and the wheels during car operation. By shifting gears, the engine can operate at its optimal power performance. Overheating of the transmission oil during operation has a significant impact, so a transmission oil cooling system is required to reduce the oil temperature. The intercooler in the oil cooling system reduces the intake air temperature of the engine, thereby improving the engine's power output.

[0003] During the assembly of the transmission oil cooling pipes to the intercooler, it is easy for them to be misconnected, leading to transmission fluid leakage at the connection point. The space at this connection point is relatively narrow, and the confirmation of whether the connection is in place mainly relies on tactile judgment. There are certain blind spots in self-inspection after assembly, and visual judgment has low accuracy, making it impossible to ensure 100% assembly qualification. Since the intercooler and transmission oil cooling pipes are not on the same plane after installation, applying paint on this basis cannot determine whether the transmission oil cooling pipes are installed in place. Directly applying paint will result in inconsistent paint seal positions, making later identification difficult.

[0004] Therefore, there is an urgent need to design a self-inspection device for the paint markings on automotive cooling system pipe connections to solve the above problems. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a self-inspection device for paint markings on automotive cooling system pipe connections, which solves the problem that during the assembly of transmission oil cooling pipes connected to the intercooler, transmission oil leakage and inconsistent paint seal positions are easily caused by improper insertion.

[0006] To achieve the above objectives, this utility model provides a self-inspection device for paint markings on automotive cooling system pipe connections, comprising:

[0007] A clamp that matches the outer diameter of the first connecting tube at the insertion point is engaged with the first connecting tube.

[0008] One side of the clamp abuts against the connection point of the first connecting tube and the second connecting tube, while the other side extends a distance A along the length of the first connecting tube. Then, an auxiliary paint pen marks the insertion position on the first connecting tube, and the paint marks determine the relative position of the two connecting tubes in the insertion state.

[0009] To ensure that the clamp can be locked onto the first connecting tube over a wider range, the clamp is matched with the outer diameter of the first connecting tube at the insertion point.

[0010] Specifically, the inner wall dimensions of the clamp are within the same tolerance range as the outer diameter of the first connecting pipe, so as to improve the matching degree between the clamp and the first connecting pipe.

[0011] Optionally, the diameter of the first connecting pipe is less than the diameter of the second connecting pipe.

[0012] Distance A is the overlap length when the two connecting pipes are properly connected and assembled. Assemble a set of connecting pipes to determine the overlap length, and then customize this device.

[0013] One end of the clamp is equipped with a handle, which serves as the handhold when applying the paint label.

[0014] Optionally, the handle is equipped with a magnetic element to fix the device in place, for adsorption, storage, and to prevent it from falling.

[0015] Optionally, the first connecting pipe is a transmission oil cooling pipe.

[0016] Optionally, the second connecting pipe is an intercooler connecting pipe.

[0017] The present utility model application has the following beneficial effects:

[0018] The diameter of the first connecting tube at the insertion point is customized. After the tubes are precisely inserted into the connection point, the insertion position is marked with an auxiliary paint pen. This ensures the first-time assembly pass rate of the insertion process, improves the first-time assembly pass rate of the product, and reduces rework time. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0025] To cool the transmission fluid during vehicle operation, the transmission fluid cooling pipes need to be connected to the intercooler. This involves inserting the transmission fluid cooling pipes into the intercooler connecting pipes. After insertion, the connection between the two pipes needs to be sealed with varnish. Varnish sealing is a common sealing method in this field, preventing fluid leakage from the connection and also preventing moisture, dust, and other impurities from entering the pipes. Improper insertion directly leads to fluid leakage, and the small space makes visual inspection difficult. After the two pipes are inserted, there is a diameter difference between them, and the varnish seal is not planar. Applying varnish seal under these conditions makes it impossible to determine whether the transmission fluid cooling pipes are installed correctly. Directly applying varnish seal will result in inconsistent seal positions, making later identification difficult, leading to ineffective processes and wasted costs.

[0026] As attached Figure 1 -Appendix Figure 4 As shown, this utility model embodiment provides a self-inspection device for paint markings on automotive cooling system pipe connections. It can solve the problem that in the assembly process of existing transmission oil cooling pipes connected to the intercooler, transmission oil leakage and inconsistent paint seal positions are easily caused by improper insertion. The self-inspection device for paint markings on automotive cooling system pipe connections includes a clamp 1 that is snapped onto the first connecting pipe. One side of the clamp 1 extends a distance A along the length of the first connecting pipe. It also includes a handle 2 and a magnetic suction component 3. Other necessary components that make up this device are not mentioned here and their conventional structures are common knowledge.

[0027] The self-inspection device for the paint marking of the automotive cooling system pipe connection specifically includes: a clamp 1 that matches the outer diameter of the first connecting pipe at the insertion point. One side of the clamp 1 is flat, and the other side extends a distance A along the length of the first connecting pipe. Since the diameter of the first connecting pipe is less than the diameter of the second connecting pipe when this device is used, the clamp 1 matches the outer diameter of the first connecting pipe, that is, the clamp 1 matches the smaller outer diameter of the connecting pipe when it is inserted. In this utility model, the first connecting pipe is the transmission oil cooling pipe, and the second connecting pipe is the intercooler connecting pipe. It is also applicable to other application scenarios. It is only necessary to adjust the distance A to correspond to the standard position when the insertion is qualified, that is, the overlap length of the two connecting pipes when the insertion is qualified. One end of the clamp 1 is provided with a handle 2, and a magnetic suction part 3 is provided on the handle 2. The device is fixed by the magnetic suction part 3 for adsorption, storage and preventing it from falling.

[0028] In use, the ends of the two connecting pipes are abutted together. For example, if the first connecting pipe is a transmission oil cooling pipe and the second connecting pipe is an intercooler connecting pipe, the diameter of the first connecting pipe is less than the diameter of the second connecting pipe. The worker holds handle 2 to pick up the device, and the flat side of clamp 1 abuts against the end of the second connecting pipe. Clamp 1 matches the outer diameter of the first connecting pipe at the insertion point, and the inner wall size of clamp 1 is within the tolerance range of the outer diameter of the first connecting pipe to ensure that there is no gap between them when they are inserted. The side of clamp 1 extending along the first connecting pipe is clamped onto the outside of the first connecting pipe. The device is firmly clamped. After clamping, use a paint pen to mark the insertion position on the first connecting pipe. The extension distance A of the clamp 1 customized by the device is the overlap length of the two connecting pipes when the insertion is qualified. The overlap length of the insertion can be determined by assembling a set of connecting pipes, and then this device is customized and marked. Next, the two connecting pipes are inserted. When the pipes reach the marked insertion position, insertion is stopped, indicating a successful connection. A positioning marking fixture is then designed to determine the relative position of the transmission oil cooling pipe and the intercooler, thus verifying proper insertion. This fixture is customized to fit the diameter of the transmission oil cooling pipe at the insertion point. It precisely clamps onto the connection between the transmission oil cooling pipe and the intercooler, and then an auxiliary paint pen marks the insertion position. This ensures a high first-pass yield for the insertion process, improving the overall first-pass yield and reducing rework time. During subsequent paint sealing, the paint pen position identifies a successful connection and proper installation, ensuring consistent paint sealing positions for easy identification in subsequent processes. After use, the device is magnetically attached to the work area using magnetic attachment 3. This magnetic design makes it easy to retrieve and use, preventing loss.

[0029] This automotive cooling system pipe connection paint marking self-inspection device is customized according to the outer diameter of the first connecting pipe at the insertion point. After accurately snapping into the connection point of the two connecting pipes, it assists in marking the insertion position with a paint pen, thereby ensuring the first-time assembly pass rate of the insertion process, improving the first-time assembly pass rate of the product, and reducing rework time. It adopts a magnetic auxiliary design, which is very convenient to take, use and store.

[0030] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
