Description

Technical Field

[0001] The utility model relates to the technical field of spring hanger testing, in particular to a spring hanger testing platform. Background Technique

[0002] Spring hanger testing platforms are specifically designed to test various springs, including constant force spring hangers and variable force spring hangers, etc. These testing platforms can complete the testing of mechanical performance indicators such as compression, tension, and torsion of springs to evaluate the quality and safety of springs. The testing platforms are usually equipped with advanced control systems and sensors, which can accurately measure the test force and displacement and provide real-time data display and analysis functions.

[0003] As the spring hanger testing platform disclosed in Chinese Patent CN220490335U, the height of the pressure plate is adjusted through an adjustment component, so that the height position of the pressure plate can be adjusted according to the length of the suspension rod of the spring hanger, and the adjustment is simple and convenient. Therefore, the spring stiffness of spring hangers of different models can be detected, and the practicability is strong. Through the setting of the reinforcing plate, the pressure plate near the notch is strengthened to prevent the columnar shell of the spring hanger from deforming the pressure plate during the process of squeezing the pressure plate, thereby affecting the test accuracy.

[0004] For this structure, although the height of the testing device can be adjusted to test spring hangers of different models, it is inconvenient to connect the spring hanger and the testing device conveniently. Therefore, we propose a spring hanger testing platform that can quickly connect the spring hanger and the testing device to improve its testing convenience. Content of the Utility Model

[0005] The purpose of the utility model is to provide a spring hanger testing platform to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A spring hanger testing platform, including a testing pull rod, a suspension ring is arranged below the testing pull rod, a connecting rod is arranged below the suspension ring, and a processing component is arranged below the testing pull rod. The processing component includes a clamping component arranged below the testing pull rod, and an anti-slip component is arranged inside the clamping component.

[0007] Preferably, the clamping component includes a support plate fixedly installed at the end of the testing pull rod, a limiting rod is fixedly installed on the top surface of the support plate, a pressure plate is slidably arranged on the outer wall of the limiting rod, a sliding rod is fixedly installed inside the support plate, a spring is sleeved on the outer wall of the sliding rod, a slider is slidably arranged on the outer wall of the sliding rod, a clamping block is fixedly installed at the bottom of the slider, and a pressing block is fixedly installed on the top surface of the slider.

[0008] Preferably, the anti-slip component includes a chute formed in the outer wall of the clamping block. A first magnet is fixedly installed on the inner wall of the chute. A second magnet is slidably disposed inside the chute. A rubber pad is fixedly installed on the side wall of the second magnet.

[0009] Preferably, the side of the clamping block away from the slider is inclined. The pressing plate is in contact with the inclined surface of the extrusion block. When it is necessary to disassemble the hanging ring from the test pull rod, press the pressing plate. Its inclined surface extrudes the inclined surface of the extrusion block, so that the extrusion block drives the slider and the clamping block to slide on the outer wall of the sliding rod, and disassembles the hanging ring from the test pull rod.

[0010] Preferably, there are two clamping blocks, which are symmetrically distributed with respect to the center line of the support plate. Under the support of the clamping blocks, the hanging ring can be clamped and lifted for testing.

[0011] Preferably, the second magnet and the first magnet repel each other magnetically. The rubber pad is made of rubber. Under the restriction of magnetic repulsion, the misaligned hanging ring and the test pull rod can be finely adjusted. Under the restriction of the rubber second magnet, the friction coefficient with the inner side of the hanging ring can be increased to prevent the hanging ring from falling off.

[0012] Preferably, there are two rubber pads, which are symmetrically distributed with respect to the center line of the support plate. The rubber pads can stably support the hanging ring.

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

[0014] 1. This spring hanger test platform is composed of a clamping component as one of its parts. When it is necessary to test the spring hanger, it is necessary to connect the hanging ring fixedly installed on the outer wall of the connecting rod in the spring hanger to the test mechanism. At this time, the support plate is clamped outside the hanging ring. The outer wall of the clamping block fixedly installed at the bottom of the slider contacts and presses the outer wall of the hanging ring. The inclined surface of the clamping block contacts and presses the hanging ring, so that the clamping block drives the slider to slide on the outer wall of the sliding rod and compresses the spring sleeved on the outer wall of the sliding rod. When the side of the clamping block away from its inclined surface contacts the inner wall of the hanging ring, the clamping block is not pressed at this time, and the spring is not compressed at this time. The spring pushes the slider and pushes the clamping block towards the inside of the hanging ring, so that the clamping block quickly installs the hanging ring outside the spring hanger. When the test is completed, press the pressing plate. The inclined surface at its end contacts and presses the inclined surface of the sliding rod, so that the sliding rod is pressed, drives the slider to slide on the outer wall of the sliding rod, compresses the spring, and makes the clamping block no longer clamped with the hanging ring (the test pull rod, the hanging ring, the connecting rod and the test mechanism are the prior art disclosed in the comparative document, so their structures are not fully described in this case).

[0015] 2. The spring hanger testing platform includes an anti-slip component as one of its parts. When the block is away from the inclined surface side and contacts the inner side of the lifting ring, the rubber pad contacts the inner wall of the lifting ring. Under the restriction of the rubber pad, the friction coefficient between the block and the inner side of the lifting ring can be increased to prevent the lifting ring from detaching from the testing mechanism during testing. When the rubber pad is squeezed, it drives the second magnetic block to slide towards the first magnetic block, causing the second magnetic block to contact the first magnetic block. After the testing is completed, when the lifting ring and the block are disassembled, the rubber pad is not squeezed. Under the restriction of magnetic repulsion, the rubber pad is pushed towards the outside of the chute. This structure can prevent the testing pull rod from directly pulling the lifting ring when the lifting ring is in a misaligned state, causing a testing accident. The operator can adjust according to the contact state between the rubber pad and the inner side of the lifting ring for safe testing. Since the force of magnetic repulsion between the second magnetic block and the first magnetic block is constant, it will not affect the accuracy of the spring hanger testing data.

Detailed Embodiment

[0023] For a clearer understanding of the technical features, objectives, and effects of the present invention, the specific embodiments of the present invention are now described with reference to the accompanying drawings.

[0024] The preferred embodiment of the spring hanger testing platform provided by the present invention is as Figures 1 to 6 shown: The spring hanger testing platform includes a testing pull rod 1;

[0025] There is a lifting ring 2 arranged below the test pull rod 1;

[0026] There is a connecting rod 3 arranged below the lifting ring 2;

[0027] And a processing component 4 arranged below the test pull rod 1. The processing component 4 includes a clamping component 41 arranged below the test pull rod 1. The clamping component 41 includes a support plate 411 fixedly installed at the end of the test pull rod 1. A limiting rod 412 is fixedly installed on the top surface of the support plate 411. A pressing plate 413 is slidably arranged on the outer wall of the limiting rod 412. A sliding rod 414 is fixedly installed inside the support plate 411. A spring 415 is sleeved on the outer wall of the sliding rod 414. A slider 416 is slidably arranged on the outer wall of the sliding rod 414. A clamping block 417 is fixedly installed at the bottom of the slider 416. An extrusion block 418 is fixedly installed on the top surface of the slider 416.

[0028] In this embodiment, when it is necessary to test the spring hanger, it is necessary to connect the lifting ring 2 fixedly installed on the outer wall of the connecting rod 3 in the spring hanger with the test mechanism. At this time, the support plate 411 is clamped outside the lifting ring 2. The outer wall of the clamping block 417 fixedly installed at the bottom of the slider 416 contacts and presses against the outer wall of the lifting ring 2. The inclined surface of the clamping block 417 contacts and presses against the lifting ring 2, causing the clamping block 417 to drive the slider 416 to slide on the outer wall of the sliding rod 414 and compress the spring 415 sleeved on the outer wall of the sliding rod 414. When the side of the clamping block 417 away from its inclined surface contacts the inner wall of the lifting ring 2, at this time, the clamping block 417 is not pressed, and at this time, the spring 415 is not compressed. The spring 415 pushes the slider 416 and pushes the clamping block 417 towards the inside of the lifting ring 2, so that the clamping block 417 quickly installs the lifting ring 2 outside the spring hanger. When the test is completed, press the pressing plate 413, and the inclined surface at its end contacts and presses against the inclined surface of the sliding rod 414, causing the sliding rod 414 to be pressed, driving the slider 416 to slide on the outer wall of the sliding rod 414, compressing the spring 415, so that the clamping block 417 no longer clamps the lifting ring 2 (the test pull rod 1, the lifting ring 2, the connecting rod 3 and the test mechanism are the prior art publicly disclosed in the comparative document, so their structures are not fully described in this case).

[0029] Furthermore, the side of the clamping block 417 away from the slider 416 is arranged in an inclined surface, and the pressing plate 413 is in contact with the inclined surface of the extrusion block 418. When it is necessary to disassemble the lifting ring 2 from the test pull rod 1, press the pressing plate 413, and its inclined surface presses against the inclined surface of the extrusion block 418, causing the extrusion block 418 to drive the slider 416 and the clamping block 417 to slide on the outer wall of the sliding rod 414, and disassemble the lifting ring 2 from the test pull rod 1.

[0030] Even further, the number of the clamping blocks 417 is two, symmetrically distributed with respect to the center line of the support plate 411. Under the support of the clamping blocks 417, the lifting ring 2 can be clamped and lifted for testing.

[0031] On the basis of Embodiment 1, a preferred embodiment of the spring hanger test platform provided by the present invention is as followsFigures 1 to 6 As shown in the figure: The anti-slip component 42 includes a chute 421 formed on the outer wall of the clamping block 417. A first magnet 422 is fixedly installed on the inner wall of the chute 421. A second magnet 423 is slidably arranged inside the chute 421. A rubber pad 424 is fixedly installed on the side wall of the second magnet 423.

[0032] In this embodiment, when the side of the clamping block 417 away from its inclined surface contacts the inner side of the hanging ring 2, the rubber pad 424 contacts the inner wall of the hanging ring 2. Under the restriction of the rubber pad 424, the friction coefficient between the clamping block 417 and the inner side of the hanging ring 2 can be increased, avoiding the separation of the hanging ring 2 from the testing mechanism during the test. When the rubber pad 424 is squeezed, it drives the second magnet 423 to slide towards the first magnet 422, making the second magnet 423 contact the first magnet 422. When disassembling the hanging ring 2 and the clamping block 417 after the test, the rubber pad 424 is not squeezed. Under the restriction of magnetic repulsion, the rubber pad 424 is pushed towards the outside of the chute 421. This structure can avoid the situation where when the hanging ring 2 is in a misaligned state, the test pull rod 1 directly pulls the hanging ring 2, causing a test accident. The operator can adjust according to the contact state between the rubber pad 424 and the inner side of the hanging ring 2 for a safe test. Since the force of magnetic repulsion between the second magnet 423 and the first magnet 422 is constant, it will not affect the accuracy of the test data of the spring hanger.

[0033] Furthermore, the second magnet 423 and the first magnet 422 repel each other magnetically. The rubber pad 424 is made of rubber. Under the restriction of magnetic repulsion, the misaligned hanging ring 2 and the test pull rod 1 can be finely adjusted. Under the restriction of the rubber second magnet 423, the friction coefficient with the inner side of the hanging ring 2 can be increased, avoiding the separation of the hanging ring 2.

[0034] In addition, the number of the rubber pads 424 is two, symmetrically distributed with respect to the center line of the support plate 411. The rubber pads 424 can stably support the hanging ring 2.

[0035] The above is only a schematic specific embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present invention shall fall within the scope of protection of the present invention. Moreover, it should be noted that the various components of the present invention are not limited to the above overall application. Each technical feature described in the specification of the present invention can be used alone according to actual needs or multiple features can be combined for use. Therefore, the present invention should reasonably cover other combinations and specific applications related to the inventive points of this case.
