Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of assembly detection, especially relates to an indirect intercooler brazing plate detection device. BACKGROUND

[0002] As a key component in the engine cooling system, the brazing plate needs to be installed during the assembly process of the core body of the indirect intercooler. The correct installation of the brazing plate is crucial in the automatic assembly process of the core body of the intercooler. Once the brazing plate is missing, misinstalled, or severely deformed, it will directly affect the performance and reliability of the subsequent process of the intercooler.

[0003] The existing detection method mainly relies on proximity switches or optical fiber sensors to detect the brazing plate. However, due to the compact structure and limited installation space of the intercooler core body, the proximity sensor has installation limitations. Although the optical fiber sensor has high sensitivity, it is high in cost and not suitable for large-scale application. In addition, due to the deformation of the brazing plate, conventional non-contact detection methods cannot adapt to this change, thereby affecting the accuracy and stability of the detection.

[0004] Therefore, we propose an indirect intercooler brazing plate detection device to solve the existing problems. UTILITY MODEL CONTENTS

[0005] The utility model aims at the problems in the background art and proposes an indirect intercooler brazing plate detection device.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: an indirect intercooler brazing plate detection device, comprising a substrate, a base, a brazing plate, and a rod body, the substrate is provided with the base, the rod body is provided on the base through a connecting assembly, and the connecting assembly is used to provide an elastic pushing force for the rod body.

[0007] The rod body can perform an extension and retraction action on the base, the brazing plate contacts the base when installed, and the brazing plate contacts the front end of the rod body to form a conductive path when installed in place.

[0008] Preferably, the connecting assembly is composed of a bushing, a mounting seat, a spring, and a cover plate, the cover plate is arranged in the base, the mounting seat is arranged on the cover plate, the bushing is slidingly arranged in the mounting seat, and the rod body is arranged on the bushing.

[0009] Preferably, the spring is arranged between the top end of the rod body and the inner wall top end of the mounting seat, and the rod body protrudes from the base under the elastic pushing force of the spring.

[0010] Preferably, the contact end of the rod body and the brazing plate is provided with a contact, and the brazing plate contacts the base and the contact to form a conductive path when installed in place.

[0011] Preferably, the wire connected to the contact is a spring cable to provide displacement when the rod performs extension and retraction.

[0012] Preferably, the substrate has slots, and two slots are symmetrically distributed relative to the substrate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] During use, the indirect intercooler brazing plate testing device of this utility model can be set at a designated position by using a bayonet with an external anchor bolt structure and connecting to an external power source. During the installation of the brazing plate of the indirect intercooler, the rod can drive the bushing to slide in the mounting base. At this time, the spring is compressed and deformed. Under the action of the spring force, the rod can extend and retract on the base. The extension and retraction of the rod can eliminate the influence caused by the deformation of the brazing plate.

[0015] Meanwhile, after the brazing plate is installed in place, it will contact the end of the rod and compress the spring. Under the action of the spring, the contact of the rod is stably pressed against the surface of the brazing plate. At this time, the brazing plate contacts the rod and the base, which is equivalent to the grounding 0V signal forming a circuit to conduct electricity. The formed conductive signal is transmitted to the HMI of the external device, so the presence of the brazing plate can be detected accurately.

[0016] The rod body of this invention can extend and retract back and forth under the action of spring force, effectively buffering and eliminating interference caused by the deformation of the brazing plate, improving the reliability of detection. When the brazing plate is installed in place, the end of the rod body contacts it to form a closed circuit. The installation status feedback can be realized intuitively and accurately through the HMI of the external equipment. It solves the problem of quickly and accurately detecting the presence of the core brazing plate through the principle of conductivity within a limited installation space and cost, ensuring the normal operation of the equipment, and greatly reducing the production cost while achieving the function.

When the brazing plate 4 is installed, it contacts the base 2. The contact end of the rod 5 and the brazing plate 4 is provided with a contact 10. After the brazing plate 4 is installed in place, it will contact the end of the rod 5. The contact 10 of the rod 5 is stably pressed against the surface of the brazing plate 4.
