Abstract
Description
Technical Field
[0001] This utility model relates to the field of automobile horn production technology, specifically to a testing device for automobile horn production. Background Technology
[0002] Car horn production refers to the industrial manufacturing process that uses professional manufacturing technology and equipment to transform raw materials such as metals, plastics, and electronic components into finished horns that meet automotive safety and acoustic standards and have sound warning functions through a series of processes including stamping, injection molding, circuit board welding, assembly, debugging, and quality inspection. It covers everything from parts manufacturing to overall assembly, ensuring stable product performance, sound quality that meets standards, and compatibility with the needs of different car models.
[0003] Existing car horn testing devices typically conduct sound intensity tests in enclosed or semi-enclosed environments. However, due to the simple internal structure of the testing chamber and the lack of sound absorption treatment, the high-intensity sound waves generated when the horn is working will be reflected multiple times by the inner wall of the chamber. The reflected sound waves are superimposed on the direct sound waves and received by the microphone sensor, resulting in falsely high or fluctuating sound intensity test values. This interference is particularly significant for low-frequency sound wave reflections. Testers need to take average values through repeated tests or rely on experience to correct the data, which not only reduces testing efficiency but also easily leads to misjudgments of product quality, affects the consistency of test results, and is not conducive to use.
[0004] Therefore, a testing device for automobile horn production is proposed. Utility Model Content
[0005] The purpose of this invention is to provide a testing device for automobile horn production, which solves the problem that existing automobile horn testing devices lack sealing and anti-interference functions, and that echoes and ambient noise affect the accuracy of horn testing during the testing process.
[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0011] Preferably, the bottom of both sides of the housing is provided with sliding grooves for use with push rods, and mounting brackets are fixedly connected to both sides of the bottom of the housing.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. This utility model uses the soundproof shell and sealing plate together to form a fully enclosed detection space inside the soundproof shell. The sound-absorbing material on the inner wall of the soundproof shell absorbs and attenuates the sound waves, effectively suppressing the superposition of direct and reflected sound waves generated when the car horn is working. This makes the sound intensity data collected by the microphone sensor closer to the true value. At the same time, the adjustment mechanism drives the trapezoidal block to move through the push rod and rotating sleeve. The inclined surface is used to make the sealing plate and the soundproof shell tightly pressed together. Combined with the sealing ring, it further blocks the infiltration of external noise, solving the problem of falsely high detection values caused by reflection interference and noise penetration in traditional devices, and ensuring the consistency of the detection results.
[0017] 2. This utility model utilizes an automatic feeding mechanism, with an electric cylinder driving a clamping frame to position and clamp the car horns transported on the production line. The cylinder drives the sound insulation shell to rise and fall, enabling the car horn to quickly connect with the power supply contacts. After feeding, the adjustment mechanism drives the screw to rotate via a motor, causing the push rod and rotating sleeve to move along a set trajectory, achieving automatic opening, closing, and pressing of the sealing plate. The entire testing process requires no manual intervention in the handling, positioning, and sealing of the car horns, reducing reliance on human experience to correct data and avoiding quality misjudgments caused by operational differences. It automates the testing of car horns, improving production line testing efficiency. Attached Figure Description

The linear guide rail and the linear bearing can improve the smoothness of the threaded sleeve 74 and prevent it from rotating during movement.
[0028] Working principle: When the conveyor belt transports the car horn to the testing station, cylinder 33 drives the soundproof shell 2 to move downwards along slide bar 12, aligning the clamping frame 32 with the car horn. Electric cylinder 31 drives the two clamping frames 32 to move towards each other, clamping the car horn and making the contacts on the top of the car horn contact the power supply contacts 4. Then, cylinder 33 resets, allowing the soundproof shell 2 to return to the inside of shell 1. Motor 72 starts, driving screw 73 to move threaded sleeve 74, causing connecting plate 8 to push push rod 9 horizontally. Rotating sleeve 10 rotates on the surface of push rod 9 and presses against the inclined surface of trapezoidal block 11, pushing sealing plate 5 forward until sealing ring 15 is tightly fitted with the bottom of soundproof shell 2, forming... The sealed testing chamber and the sound-absorbing material on the inner wall of the soundproof shell 2 absorb reflected sound waves. The microphone sensor 6 collects the direct sound wave intensity data and transmits it to the controller for analysis. This solves the problem of falsely high test values caused by reflection interference and noise penetration in traditional devices, ensuring the consistency of test results. After the test is completed, the motor 72 reverses and drives the push rod 9 to retract. After the rotating sleeve 10 stops pressing the trapezoidal block 11, the sealing plate 5 automatically resets. After the cylinder 33 lowers the soundproof shell 2, the control clamping frame 32 resets. The electric cylinder 31 releases the car horn and makes it fall back onto the conveyor belt, automatically completing the car horn test. This reduces the reliance on human experience to correct data, avoids quality misjudgments caused by operational differences, and improves the testing efficiency of the production line.
