Description

Technical Field

[0001] This utility model relates to the field of spring testing, and in particular to a spring testing device that can be quickly replaced. Background Technology

[0002] In fields such as machinery manufacturing, automotive parts, and electronic equipment, the performance testing of springs (such as stiffness, elastic limit, and fatigue life) is a core link in ensuring the operational stability of downstream products. Springs need to be accurately tested to verify whether they meet design standards, so as to avoid equipment jamming, component damage, or even safety accidents due to substandard performance.

[0003] A spring testing device, disclosed in Publication No. CN210953292U, includes a workbench, a durability testing device, and an outer diameter testing device. This device can conveniently and quickly test the outer diameter of a batch of tension springs using the outer diameter testing device. For some tension springs that do not affect the assembly effect, the durability testing device can be used to perform performance tests on the springs. However, this device can only test the springs and lacks a buffer protection function. During the testing process, the springs are prone to deformation and popping out or shifting when subjected to force, which not only affects the testing accuracy but also easily injures the operator, seriously affecting the safety and stability of the testing.

[0004] Therefore, it is necessary to design a spring detection device that can quickly install and replace positioning slots of different specifications to detect the centering and limiting of the spring while providing buffer protection, facilitating the detection of springs of different diameters, preventing springs from popping out and shifting, and improving the safety and accuracy of the detection. Utility Model Content

[0005] To overcome the shortcomings of the current device, which lacks buffer protection and is prone to deformation, popping out, or displacement of the spring during the testing process, affecting testing accuracy and potentially injuring operators, thus seriously impacting testing safety and stability, this invention provides a quick-change spring testing device that can be installed and replaced with positioning slots of different specifications to perform spring centering and limiting testing while providing buffer protection. This device is suitable for testing springs of different diameters, prevents spring popping out and displacement, and improves testing safety and accuracy.

[0006] The technical solution is as follows: A quick-changeable spring detection device includes a detector, a slide rail, a slide table, a placement table, a positioning groove, a limiting component, and a protective component. The detector is connected to slide rails on both the left and right sides, and a slide table is slidably connected between the slide rails. The slide table is slidably connected to the detector, and a placement table is connected to the slide table. A positioning groove is engaged in the middle of the placement table. A limiting component for limiting the positioning groove is provided on the placement table, and a protective component for preventing the spring from popping out is provided on the upper part of the placement table.

[0007] In one embodiment, the limiting component includes a push rod, a limiting block, a first telescopic spring, a rack, and a gear. Push rods are slidably connected to both the front and rear parts of the placement platform, and the push rods are slidably connected to the slide. A limiting block is connected to the side of the push rods that are close to each other, and the limiting block is engaged with the positioning groove. A first telescopic spring is connected between the push rod and the placement platform. A rack is connected to the lower side of the push rod. A gear is rotatably connected to the lower side of the middle part of the placement platform, and the rack meshes with the gear.

[0008] In one embodiment, the push rods are all T-shaped.

[0009] In one embodiment, the protective component includes a mounting frame, a buffer frame, and a second telescopic spring. The mounting frame is snapped onto the upper part of the placement platform, and multiple buffer frames are slidably connected to the mounting frame. Each buffer frame is connected to the mounting frame by a second telescopic spring.

[0010] In one embodiment, the sides of the buffer frames that are close to each other are both curved.

[0011] In one embodiment, the buffer frames are evenly distributed along the mounting frame.

[0012] This utility model has the following advantages: 1. Based on the diameter of the spring, this utility model uses a push rod, a first telescopic spring, a rack and gear to make the limiting block move and engage with the positioning groove of the appropriate specification. Then, the spring is installed for testing. The installation frame limits the position, and the buffer frame and the second telescopic spring provide buffer protection. This allows for the quick installation and replacement of positioning grooves of different specifications to test the centering and limiting of the spring while providing buffer protection. It is convenient for testing springs of different diameters, prevents the spring from popping out and shifting, and improves the safety and accuracy of the test.

[0013] 2. This utility model allows for easy installation and removal of springs for testing by manually pulling the slide table along the slide rail, installing a suitable positioning groove, engaging the mounting frame with the placement platform, installing the spring, pushing the slide table to move and reset, and then starting the testing instrument to perform a compression test on the spring. This facilitates quick spring replacement, shortens installation time, and improves testing efficiency. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0021] A quick-change spring detection device, such as Figures 1-5 As shown, the device includes a detector 1, a slide rail 2, a slide table 3, a placement platform 4, a positioning groove 10, a limiting component, and a protective component. The detector 1 is connected to the slide rail 2 on both the left and right sides. The slide table 3 is slidably connected between the slide rails 2. The slide table 3 is slidably connected to the detector 1. The placement platform 4 is connected to the slide table 3. The positioning groove 10 is engaged in the middle of the placement platform 4. The placement platform 4 is provided with a limiting component for limiting the positioning groove 10. The upper part of the placement platform 4 is provided with a protective component to prevent the spring from popping out.

[0022] like Figure 3 and Figure 4 As shown, the limiting assembly includes a push rod 5, a limiting block 6, a first telescopic spring 7, a rack 8, and a gear 9. The push rod 5 is slidably connected to both the front and rear parts of the placement platform 4. The push rod 5 is slidably connected to the slide table 3. The push rod 5 is T-shaped for easy pushing. The sides of the push rods that are close to each other are connected to the limiting block 6. The limiting block 6 is engaged with the positioning groove 10. The first telescopic spring 7 is connected between the push rod 5 and the placement platform 4. The rack 8 is connected to the lower side of the push rod 5. The gear 9 is rotatably connected to the lower side of the middle part of the placement platform 4. The rack 8 meshes with the gear 9.

[0023] like Figure 1 , Figure 2 and Figure 5As shown, the protective assembly includes a mounting frame 11, a buffer frame 12, and a second telescopic spring 13. The mounting frame 11 is snapped onto the upper part of the placement platform 4. Three buffer frames 12 are slidably connected to the mounting frame 11. The sides of the buffer frames 12 that are close to each other are arc-shaped to facilitate fitting the shape of the springs. The buffer frames 12 are evenly distributed along the mounting frame 11. Each buffer frame 12 is connected to the mounting frame 11 by a second telescopic spring 13.

[0024] When spring testing is required, this device can be used. The testing instrument 1 is brought into contact with the ground. The slide table 3 is then manually pulled along the slide rail 2. A suitable positioning groove 10 is selected based on the spring's diameter. Next, the front push rod 5 is manually pushed, compressing the first telescopic spring 7 and causing the front limiting block 6 to move. Simultaneously, the front rack 8 moves, meshing with the gear 9, causing the gear 9 to rotate. The gear 9 meshes with the rear rack 8, causing the rear rack 8 to move, which in turn moves the rear push rod 5 and limiting block 6, compressing the first telescopic spring 7. The push rods 5 are all T-shaped. The positioning groove 10 is then picked up and engaged with the placement table 4, passing through the push rod 5. The push rod 5 is then released, causing the first telescopic spring 7 to rebound. The push rod 5 moves back to its original position, moving the limiting block 6 back to its original position and engaging with the positioning groove 10, thus fixing the positioning groove 10. The mounting frame 11 is then engaged with the placement table 4, and the spring is placed through the mounting frame 11 into the positioning groove. The spring is centered in the slot 10, then the slide 3 is moved and reset. The tester 1 is then started to perform a compression test on the spring. During the test, the spring is limited by the mounting frame 11. When the spring pops out, it is buffered and protected by the buffer frame 12 and the second telescopic spring 13. The sides of the buffer frames 12 that are close to each other are arc-shaped and are evenly distributed along the mounting frame 11. This allows for quick installation and replacement of springs of different specifications. The positioning slot 10 is used to center and limit the spring for testing while providing buffer protection. This is convenient for testing springs of different diameters, preventing the spring from popping out and shifting, and improving the safety and accuracy of the test. After the test is completed, the slide 3 is pulled out along the slide rail 2 by hand, and the spring is removed. The next spring to be tested is then placed in the positioning slot 10, and the slide 3 is moved and reset. The spring is then tested again. This makes it convenient to load and unload the spring for testing, facilitates quick spring replacement, shortens the installation time, and improves the testing efficiency. The above operation is repeated to test the springs until all tests are completed.
