Description

Technical Field

[0001] This utility model relates to the field of elasticity testing technology for butterfly-shaped elastic dampers, specifically to an elasticity testing device for butterfly-shaped elastic dampers. Background Technology

[0002] A butterfly-shaped elastic damper is a device installed on the lead screw of a universal rolling mill to eliminate thread backlash, reduce bounce during steel rolling, maintain workpiece dimensions, and improve mill control accuracy. Because it is mainly composed of various elastic components, its elasticity can decrease or even fail after prolonged use. Therefore, an elasticity testing device is needed to inspect and address the butterfly-shaped elastic damper.

[0003] While existing elasticity testing devices meet users' needs to a certain extent, they still have certain shortcomings during use. Specifically, the damping body is prone to displacement during butterfly-shaped elastic damping body testing, leading to deviations in the pressing position and inaccurate elastic deformation and force data, thus affecting the reliability of the test results. Furthermore, the testing platform easily retains dust, metal shavings, and other impurities. These impurities accumulate in the damping body placement groove, causing uneven placement of the damping body and indirectly affecting the force distribution during pressing. Manual cleaning is not only cumbersome but also prone to damaging the testing platform during the cleaning process, increasing maintenance costs. Therefore, this invention designs a butterfly-shaped elastic damping body elasticity testing device to solve the above problems. Utility Model Content

[0014] Compared with the prior art, the advantages of this utility model are: the structure of this utility model is scientific and reasonable, and it is safe and convenient to use.

[0015] 1. The bidirectional threaded rod drives the moving plate to slide the clamping plate along the placement groove. The clamping distance can be flexibly adjusted according to the size of the butterfly-shaped elastic damping body to match its butterfly profile. During the sliding process, the clamping plate is limited by the moving plate and the end face of the base, so the movement is stable and there is no deviation. This ensures that the damping body is firmly clamped and the force is uniform, avoiding data deviation caused by displacement during testing and improving the reliability of the test results.

The scale and the moving frame work together to accurately measure the moving distance of the reset plate, realizing dual data acquisition and improving detection accuracy. The electric telescopic rod drives the limit plate to rise and fall. The lower limit of pressing can be set according to the detection requirements to avoid excessive pressing and damage to the damping body. At the same time, it ensures the consistency of pressing depth of different test batches, which is convenient for data comparison.

[0017] 3. The pressing plate drives the moving rod and the moving plate to slide in the fixed box, and the one-way valve forms a negative pressure adsorption. The impurities in the placement slot are sucked into the collection box through the dust suction slot and the dust suction pipe. No manual cleaning is required, which can keep the placement slot flat and clean, avoid impurities from affecting the placement stability of the damping body, indirectly ensure the accuracy of test data, and reduce manual maintenance costs.

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] Example: Figure 1-4As shown, the present invention provides a technical solution: a butterfly-shaped elastic damping body elastic detection device, including a base 1, a mounting frame 2 fixedly connected to the top of the base 1, a hydraulic rod 3 set at the top of the mounting frame 2, a pressing plate 4 fixedly connected to the bottom of the hydraulic rod 3, a pressure gauge 5 set at the top of the pressing plate 4, an electric telescopic rod 6 fixedly connected to the top of the base 1, and a limit plate 7 installed at the top of the electric telescopic rod 6 by screws.

[0027] Two spring telescopic rods 8 are installed on the top of the base 1 by screws. The tops of the two spring telescopic rods 8 are connected by a reset plate 9. One end of the base 1 is rotatably connected to a bidirectional threaded rod 10. Both ends of the bidirectional threaded rod 10 are threadedly connected to an adjustment plate 11. One end of the adjustment plate 11 is fixedly connected to a clamping plate 12.

[0028] A collection box 13 is fixedly connected to one end of the base 1, and a fixed box 14 is fixedly connected to the top of the collection box 13. A suction pipe 15 is fixedly connected to one end of the collection box 13, and the other end of the suction pipe 15 is fixedly connected to one end of the base 1. A suction groove 16 is provided on the base 1 at the position corresponding to one end of the suction pipe 15. A moving rod 17 is fixedly connected to one end of the pressing plate 4, and a moving plate 18 is installed at the bottom of the moving rod 17 by screws. A one-way valve 19 is fixedly connected to the bottom of the fixed box 14 and one end of the fixed box 14.

[0029] The top surface of the limiting plate 7 can contact the bottom surface of the pressing plate 4, which facilitates the limiting treatment of the pressing plate 4 and avoids the problem of excessive detection of the elastic damping body.

[0030] A scale is fixedly connected to one end of the top of the base 1, and a movable frame is fixedly connected to one end of the reset plate 9. The movable frame is slidably connected to the outside of the scale, which facilitates the measurement of the moving position of the reset plate 9, and thus the deformation of the core of the butterfly elastic damping body can be measured.

[0031] The bottom of the base 1 has a placement groove for placing the elastic damping body. The clamping plate 12 is slidably connected inside the placement groove. The end face of the adjusting plate 11 is in contact with the end face of the base 1 to ensure the stability of the movement of the adjusting plate 11, thereby ensuring the stability of the movement of the clamping plate 12. This facilitates the placement and fixing of the elastic damping body, thereby ensuring the stability of the elastic damping body during the pressing process and ensuring the test data of the elastic damping body.

[0032] A rubber frame is glued to the outside of the moving rod 17. The moving rod 17 is slidably connected to the inside of the fixed box 14. The one-way valve 19 at the bottom of the fixed box 14 allows air to enter inward, and the one-way valve 19 at one end of the fixed box 14 allows air to exit outward. This facilitates the adsorption of impurities into the collection box 13, collecting impurities inside the placement slot. This facilitates the subsequent placement of the elastic damping body and ensures the stability of the placement of the elastic damping body.

[0033] Place the butterfly-shaped elastic damper into the placement slot at the top of the base 1, rotate the bidirectional threaded rod 10 at one end of the base 1, and the adjusting plate 11 on the outside of the bidirectional threaded rod 10 slides along the end face of the base 1 due to the threaded connection and contacts the end face of the base 1. The adjusting plate 11 drives the clamping plate 12 at one end to slide synchronously along the placement slot until the two clamping plates 12 are in contact with both sides of the material. The clamping and fixing are completed according to the size of the butterfly-shaped damper to avoid displacement during testing.

[0034] Start the electric telescopic rod 6 at the top of the base 1. The electric telescopic rod 6 extends or retracts, which drives the limit plate 7 to rise and fall, adjusting the limit plate 7 to the preset height. The top surface of the limit plate 7 can contact the bottom surface of the pressing plate 4 to prevent excessive subsequent pressing from damaging the damping body.

[0035] Start the hydraulic rod 3 at the top of the mounting bracket 2. The hydraulic rod 3 shortens and moves the pressing plate 4 downward. After the pressing plate 4 contacts the reset plate 9, it pushes the butterfly-shaped elastic damping body and applies pressure. The pressure gauge 5 on the top of the pressing plate 4 displays the pressure data in real time and records the pressure on the damping body simultaneously. The moving frame at one end of the reset plate 9 slides along the scale on the top of the base 1. The displacement of the moving frame is read through the scale, which is the elastic deformation of the damping body. After the preset pressure or displacement detection is completed, the hydraulic rod 3 extends and moves the pressing plate 4 to reset. The spring telescopic rod 8 pushes the reset plate 9 back up, completing one detection cycle.

[0036] When the pressing plate 4 moves downward, it simultaneously drives the moving rod 17 at one end to slide downward. The moving rod 17 drives the moving plate 18 at the bottom to move downward in the fixed box 14, creating a negative pressure inside the fixed box 14. At this time, the one-way valve 19 at the bottom of the fixed box 14 opens, allowing the air inside the fixed box 14 to be discharged. When the pressing plate 4 returns to its original position, the moving rod 17 drives the moving plate 18 to move upward, increasing the pressure inside the fixed box 14. The one-way valve 19 at the bottom opens, and the one-way valve 19 at one end closes. Impurities enter the collection box 13 for storage with the airflow. Through the linkage of the pressing action and the cleaning action, the automatic cleaning of the placement slot is achieved, ensuring that the damping body is placed flat afterward.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
