Description

Technical Field

[0001] This utility model relates to the field of testing mechanism technology, and in particular to a spring testing mechanism. Background Technology

[0002] In existing industrial production lines, especially in the manufacturing process of products involving spring assembly, traditional practices often neglect the quality inspection of individual springs. As a core component widely used in machinery, automotive parts, electronic equipment, and many other industrial fields, the quality of springs directly affects the performance, safety, and lifespan of the final product. However, in traditional production line operations, due to the pursuit of production efficiency and cost control, springs typically do not undergo individual quality inspection steps before assembly, a practice that poses significant quality risks.

[0003] Specifically, untested springs may have issues such as dimensional deviations, material defects, and substandard elastic performance. Dimensional deviations may prevent the spring from fitting precisely during installation, affecting the product's assembly accuracy and stability; material defects may cause the spring to break during use, leading to equipment malfunctions or even safety accidents; and substandard elastic performance will directly affect the product's functionality, significantly reducing its shock absorption and energy storage effects.

[0004] Furthermore, with increasingly stringent market demands for product quality and consumers' growing focus on brand reputation, neglecting spring quality testing is no longer sufficient to meet current market needs. Companies face risks such as returns, compensation claims, and customer loss due to product quality issues. This not only harms their economic interests but also severely impacts their brand image and market competitiveness.

[0005] Therefore, in view of the above problems, there is an urgent need for a technical solution that can efficiently and accurately perform quality inspection on individual springs to ensure that each spring meets the predetermined quality standards before entering the assembly stage; to this end, this application proposes a spring inspection mechanism.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1-3 As shown, this utility model embodiment proposes a spring detection mechanism, including:

[0023] A base plate 14 is provided, on which four columns 15 are mounted. A top plate 17 is mounted on the upper end of the four columns 15. An electric cylinder 1 with a guide rod is mounted on the top plate 17. A connecting plate 2 is mounted on the output end of the electric cylinder 1 with a guide rod. In order to ensure the stable up and down movement of the connecting plate 2, a mounting plate is fixed to the output end of the electric cylinder 1 with a guide rod. The connecting plate 2 is mounted on the bottom of the mounting plate. Two guide rods 22 are fixedly connected to the upper end of the mounting plate. Two guide sleeves 21 are mounted on the top plate 17. The guide rods 22 pass through the guide sleeves 21 and are slidably connected to them.

[0024] Two test seats 3 are installed at the bottom of the connecting plate 2. A pressure sensor 18 is installed on the test seat 3, and a test rod 4 connected to the pressure sensor 18 is installed on the test seat 3.

[0025] A bracket 16 is installed on the base plate 14. A sliding plate 8 is slidably connected to the bracket 16. Two guide rails 9 are installed on the upper end of the bracket 16. Guide blocks slide on the guide rails 9. The sliding plate 8 is fixed to the upper end of the guide blocks, which can ensure the stable sliding of the sliding plate 8.

[0026] Two spring seats 6 opposite to the test rod 4 are installed on the upper end of the sliding plate 8. Two second cylinders 13 are installed on the sliding plate 8. A second proximity switch 20 for use by the second cylinders 13 is installed on the spring seats 6. A switching block 7 that is slidably connected to the spring seats 6 is fixed at the output end of the second cylinders 13. There is a through groove on the spring seat 6. The switching block 7 is set opposite to the through groove. The through groove can hold a spring. The two spring seats 6 can be the same or different. The purpose of different seats is to test springs of different sizes.

[0027] It also includes a material collection mechanism, which includes two material boxes 11 placed on the base plate 14. Two material guide blocks 10 opposite to the material boxes 11 are installed on the bracket 16. The material guide blocks 10 are arranged opposite to the two spring seats 6. The material guide blocks 10 are cylindrical and are arranged opposite to the through groove.

[0028] One of the spring seats 6 is equipped with a first proximity switch 5, and a first cylinder 12 is installed on the bracket 16. The output end of the first cylinder 12 is fixedly connected to the sliding plate 8. A buffer seat is installed on the bracket 16, and a buffer 19 for buffering the sliding plate 8 is installed on the buffer seat.

[0029] The workflow is as follows: The large and small springs are manually placed into the two spring seats 6. The first proximity switch 5 detects the signal, and the first cylinder 12 retracts, causing the sliding plate 8 to move, moving the two spring seats 6 directly below the test rod 4. The electric cylinder 1 with guide rod extends, causing the connecting plate 2 and the two test rods 4 to press down to test position one. Two pressure sensors 18 detect the force of the two springs at position one. Then, the electric cylinder 1 with guide rod continues to press down to position two, and the two pressure sensors 18 detect the force of the two springs at position two. After the test, the electric cylinder 1 with guide rod resets. If the spring test result is unqualified, the two second cylinders 13 retract, causing the switching block 7 to move. The spring, no longer supported, will fall into the corresponding material box 11 through the feeding guide block 10 due to gravity. If the test is qualified, the spring is manually removed, completing one cycle.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
