Description

Technical Field

[0001] This utility model relates to the field of coupling flexible component stiffness measurement technology, and more specifically to a coupling flexible component axial stiffness measurement device. Background Technology

[0002] A coupling is a device that connects two shafts or a shaft and a rotating component, allowing them to rotate together during motion and power transmission. Under normal circumstances, they do not disengage. Sometimes, they also serve as a safety device to prevent the connected components from bearing excessive loads, providing overload protection. Flexible couplings, on the other hand, have internal elastic elements that provide a certain degree of cushioning. To ensure the reliability, system stability, and lifespan safety of the coupling under actual operating conditions, it is necessary to use measuring devices to measure the axial stiffness of the coupling's flexible elements.

[0003] For example, the prior art publication number CN221506231U discloses an axial stiffness measuring device for coupling flexible components. This utility model improves measurement accuracy by horizontally installing the coupling flexible component under test, reducing the influence of the weight of the adapter itself on the measurement results when vertically installed. It avoids the danger of the flexible component tipping over due to the use of weights in traditional methods, and reduces the complexity of traditional measurements using multiple dial indicators, making the measurement process simpler and more convenient.

[0004] However, the existing technology described above still has the following problems in use: When using traditional coupling flexible component axial stiffness measuring devices, operators cannot effectively observe changes in the coupling flexible component, which affects the intuitiveness of the axial stiffness measurement. Based on this, this utility model provides a coupling flexible component axial stiffness measuring device that is easier to observe. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a device for measuring the axial stiffness of a coupling flexible component. The device fixes the coupling flexible component using two positioning plates and two connecting shafts, and uses a laser rangefinder to measure displacement distance and a pressure sensor to measure pressure. Operators analyze and calculate the displacement distance and pressure data to determine the axial stiffness of the coupling flexible component. Simultaneously, a measuring pen at the bottom of the positioning plates draws a path on the marking plate surface, facilitating subsequent monitoring of the axial changes in the coupling flexible component, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for measuring the axial stiffness of a coupling flexible component, comprising a testing base, with support plates fixedly mounted on both sides of the top of the testing base, and an electric push rod fixedly passing through the interior of each of the two support plates. A connecting plate is fixedly mounted on the piston rod of the electric push rod, and a connecting shaft for placing the coupling is connected to the connecting plate. A measuring component is fixedly mounted on one side of each of the two support plates that are close to each other. A positioning plate is fitted onto the outer wall of each of the two connecting shafts. An installation hole is provided at the bottom of the positioning plate, and a measuring pen is detachably installed inside the installation hole. A groove is provided at the top of the testing base, and a marking plate is provided inside the groove.

[0007] In a preferred embodiment, the measuring component includes a laser rangefinder, which is detachably fixed to a support plate, facilitating subsequent disassembly, maintenance, and replacement by personnel.

[0008] In a preferred embodiment, mounting grooves are provided on the adjacent sides of the two positioning plates. A pressure sensor is fixedly installed inside the mounting groove. The pressure sensor is in contact with the outer wall of the coupling flexible component. The pressure sensor can automatically detect the force on the coupling flexible component. The axial stiffness of the coupling flexible component can be calculated using the detected force and distance.

[0009] In a preferred embodiment, two slots are provided on the outer wall of the front end of each of the two measuring pens, and a round hole is provided on the front end of each of the two positioning plates. A spring pin is fixed inside the round hole. One end of the spring pin passes through the positioning plate and is inserted into the slot. The measuring pen is fixed by the insertion method, which makes it easy for the staff to quickly adjust the height of the measuring pen.

[0010] In a preferred embodiment, the inner walls of the front and rear sides of the groove are provided with slots, and each slot is provided with a locking block. The locking block is connected to the inner wall of the slot by multiple return springs. The outer walls of the front and rear sides of the signboard are provided with slots that are adapted to the locking blocks. The locking blocks engage with the slots to fix the signboard, which facilitates the quick replacement of the signboard by the staff.

[0011] In a preferred embodiment, the top front and rear sides of the detection seat are provided with adjustment slots, and each adjustment slot is provided with an adjustment plate. The adjustment plate is fixed to the locking block by multiple connecting rods, and multiple reset springs are respectively passed through the multiple connecting rods. The multiple reset springs can push the locking block to engage with the locking slot, thereby improving the firmness of the marking plate.

[0012] In a preferred embodiment, the top of the detection seat is provided with multiple fixing holes, which are evenly distributed on the top of the detection seat. The provision of multiple fixing holes can effectively improve the stability of the detection seat.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model uses two positioning plates and two connecting shafts to fix the flexible coupling component, and uses a laser rangefinder to measure the displacement distance and a pressure sensor to measure the pressure. The operator analyzes and calculates the displacement distance and pressure data to obtain the axial stiffness of the flexible coupling component. At the same time, the measuring pen at the bottom of the positioning plate draws a path on the surface of the marking plate, which makes it easy for the operator to check the axial changes of the flexible coupling component later.

[0015] 2. Multiple reset springs push the locking block into the slot, which effectively improves the stability of the signboard. At the same time, moving the adjusting plate moves multiple connecting rods, which in turn move the locking block out of the slot, allowing the signboard to be removed for replacement. The structure is simple and the operation is very quick. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Refer to the instruction manual appendixFigures 1-5 This utility model provides a device for measuring the axial stiffness of a coupling flexible component, including a testing seat 1. The testing seat 1 has multiple fixing holes 22 on its top, which are evenly distributed on the top of the testing seat 1. The multiple fixing holes 22 can greatly improve the installation firmness of the testing seat 1. Support plates 2 are fixedly provided on both sides of the top of the testing seat 1. Electric push rods 3 are fixedly inserted through the inside of the two support plates 2. A connecting plate 4 is fixedly provided on the piston rod of the electric push rod 3. A connecting shaft 5 for placing the coupling is connected to the connecting plate 4.

[0024] Measurement components 6 are fixedly installed on the side of the two support plates 2 that are close to each other. Specifically, the measurement components 6 include a laser rangefinder 61, which is detachably fixed to the support plate 2 by bolts. Mounting grooves 62 are opened on the side of the two positioning plates 7 that are close to each other. Pressure sensors 63 are fixedly installed inside the mounting grooves 62 and the pressure sensors 63 are in contact with the outer wall of the coupling flexible part.

[0025] The outer walls of the two connecting shafts 5 are fitted with positioning plates 7. The bottom of the positioning plates 7 is provided with mounting holes 8. A measuring pen 9 can be detachably installed inside the mounting holes 8. The top of the detection seat 1 is provided with a groove 10. A marking plate 11 is provided inside the groove 10.

[0026] In actual use, the operator first places the flexible coupling component to be tested between two positioning plates 7, and uses an electric push rod 3 to drive the positioning plate 7 to translate, so that the positioning plate 7 fits onto the flexible coupling component. The connecting shaft 5 is also inserted into the flexible coupling component for fixation. Then, the electric push rod 3 continues to drive the connecting shaft 5 and the positioning plate 7 to translate. The laser rangefinder 61 on the support plate 2 detects the distance between the positioning plate 7 and the support plate 2 in real time, and the pressure sensor 63 detects the pressure on the flexible coupling component in real time. The computer data acquisition and processing system then analyzes and calculates the data to obtain the axial stiffness of the flexible coupling component. At the same time, the measuring pen 9 at the bottom of the positioning plate 7 draws a path on the surface of the marking plate 11, which is convenient for the operator to check the axial changes of the flexible coupling component later.

[0027] Refer to the instruction manual appendix Figures 4-5 Two upper and lower slots 12 are provided on the outer wall of the front end of each of the two measuring pens 9. A round hole 13 is provided on the front end of each of the two positioning plates 7. A spring pin 14 is fixedly installed inside the round hole 13. One end of the pin of the spring pin 14 passes through the positioning plate 7 and is inserted into the slot 12. Before installing the coupling flexible component, the operator can pull the pin on the spring pin 14 out of the slot 12, and then push the measuring pen 9 to move up and separate it from the marking plate 11 before installing the coupling flexible component. This avoids the measuring pen 9 making marking lines on the marking plate 11 that will affect subsequent observation.

[0028] The inner walls of the front and rear sides of the groove 10 are provided with slots 15, and each slot 15 is provided with a locking block 16. The locking block 16 is connected to the inner wall of the slot 15 by multiple return springs 17. The outer walls of the front and rear sides of the marking plate 11 are provided with slots 18 that are adapted to the locking block 16. The locking block 16 is engaged with the slot 18. The top of the detection seat 1 is provided with adjustment slots 19 on the front and rear sides. Each adjustment slot 19 is provided with an adjustment plate 20. The adjustment plate 20 is fixed to the locking block 16 by multiple connecting rods 21, and the multiple connecting rods 21 pass through multiple return springs 17 respectively.

[0029] Multiple reset springs 17 push the locking block 16 into the slot 18, thereby effectively improving the stability of the label plate 11. At the same time, the adjustment plate 20 is moved to move multiple connecting rods 21, and the multiple connecting rods 21 move the locking block 16 out of the slot 18, so that the label plate 11 can be taken out for replacement. The structure is simple and the operation is very quick.
