[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0027] Example 1
[0028] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a static balance testing device for a punch press flywheel. The punch press flywheel static balance testing device includes a main body component 100 and a fixing component 200. The two work together to protect the placement shaft and prevent the flywheel from falling off.
[0029] The main component 100 includes a balance testing machine 101, on which a placement shaft 102 is provided.
[0030] The balancing testing machine 101 is a specialized device for inspecting the dynamic balance of rotating mechanical components. Its core function is to measure and analyze the imbalance of rotating components to ensure stability during high-speed rotation, reduce vibration, noise, and wear, extend equipment life, and improve operational safety. The placement shaft 102 on the balancing testing machine 101 is the core mechanical component that supports and drives the rotating component under test. Inspection is typically performed by fitting the workpiece onto the outside of the placement shaft 102.
[0031] The fixing component 200 is sleeved on the outside of the placement shaft 102 and includes a fixing member 201. The fixing member 201 includes a clamp 2011. A connecting rod 2012 is inserted into the inner wall of the clamp 2011. A balance testing machine 101 is sleeved on the outside of the connecting rod 2012. A protective block 2013 is fixed to one end of the connecting rod 2012.
[0032] The fixing components 200 consist of two sets, both of which are sleeved on the outside of the placement shaft 102.
[0033] The protective block 2013 is used to protect the connecting rod 2012 and prevent it from falling off during movement.
[0034] When it is necessary to protect the placement shaft 102 to prevent it from falling off, the connecting rod 2012 is rotated. The rotation of the connecting rod 2012 causes the clamp 2011 to rotate. By moving the clamp 2011 to the outside of the placement shaft 102, the placement shaft 102 can be protected.
[0035] Example 2
[0036] Reference Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0037] Specifically, the fixed component 200 also includes a rotating component 202, which includes a torsion spring 2021. The torsion spring 2021 is sleeved on the outside of the connecting rod 2012. One end of the torsion spring 2021 is fixed to one end of the protective block 2013, and the other end is fixed to one end of the balance testing machine 101.
[0038] When it is necessary to open the clamp 2011, the connecting rod 2012 is rotated. The rotation of the connecting rod 2012 causes the protective block 2013 to rotate. The rotation of the protective block 2013 will apply a torsional force to the torsion spring 2021. At this time, the connecting rod 2012 will cause the clamp 2011 to open.
[0039] When it is necessary to protect the placement shaft 102 to prevent it from falling off, the connecting rod 2012 is rotated. At this time, the force of the torsion spring 2021 can make the connecting rod 2012 return to its original position. The movement of the connecting rod 2012 can drive the clamp 2011 to move to the outside of the placement shaft 102, thereby protecting the placement shaft 102.
[0040] Specifically, the inner wall of the clamp 2011 is provided with multiple friction blocks 2022.
[0041] The friction block 2022 on the inner wall of the clamp 2011 can be called anti-slip teeth. It is a structural design that achieves a specific function by increasing the friction of the contact surface. Its core function is to enhance the friction between the clamp 2011 and the fixed object through local protrusions or high-friction materials, so as to prevent slippage, loosening or displacement.
[0042] Specifically, a rotating rod 2023 is fixed to one end of the connecting rod 2012, and a handle 2024 is fixed to one end of the rotating rod 2023.
[0043] By rotating the handle 2024, the rotation of the handle 2024 will drive the rotating rod 2023 to rotate, and the rotation of the rotating rod 2023 will drive the connecting rod 2012 to rotate.
[0044] Specifically, the fixing component 200 also includes a limiting component 203, which includes a locking block 2031. One end of the locking block 2031 is fixed with a fixing plate 2032, which is sleeved on the outside of the rotating rod 2023.
[0045] The fixed plate 2032 is used to support the locking block 2031. By rotating the handle 2024, the rotation of the handle 2024 drives the rotation rod 2023 to rotate, which in turn drives the fixed plate 2032 to rotate.
[0046] Example 3
[0047] Reference Figure 4 and Figure 5 This is the third embodiment of the present invention, which is based on the first two embodiments.
[0048] Specifically, a fixing ring 2033 is fitted on the outer side of the card block 2031, and multiple card slots 2033-1 are opened on the inner wall of the fixing ring 2033.
[0049] By moving the locking block 2031, the locking block 2031 will separate from the locking slot 2033-1. At this time, the handle 2024 can be rotated. The handle 2024 drives the rotating rod 2023 to rotate, and the rotation of the rotating rod 2023 will drive the fixed plate 2032 to rotate.
[0050] Specifically, each of the fixed plates 2032 has two support plates 2034 fixed at one end, and each of the two ends of the locking block 2031 has a slider 2035 fixed thereon, which slides on the inner wall of the support plate 2034.
[0051] By moving the locking block 2031, the movement of the locking block 2031 causes the slider 2035 to move. The slider 2035 will slide on the inner wall of the support plate 2034. The slider 2035 makes the locking block 2031 more stable when moving.
[0052] Specifically, a spring 2036 is fixed to the bottom of the locking block 2031, the other end of the spring 2036 is fixed to the surface of the rotating rod 2023, and a pressing rod 2037 is fixed to one end of the locking block 2031.
[0053] By moving the pressing rod 2037, the pressing rod 2037 drives the locking block 2031 to move. The movement of the locking block 2031 drives the slide bar 2035 to move. The slide bar 2035 slides on the inner wall of the support plate 2034. The movement of the locking block 2031 applies pressure to the spring 2036. At this time, the locking block 2031 separates from the slot 2033-1. By rotating the handle 2024, the handle 2024 drives the rotating rod 2023 to rotate. The rotation of the rotating rod 2023 drives the fixed plate 2032 to rotate, which can open the clamp 2011. Then, by releasing the locking block 2031, the rebound force of the spring 2036 can make the locking block 2031 engage with the slot 2033-1.
[0054] Then, the placement shaft 102 is placed on the balance testing machine 101. By moving the locking block 2031, the locking block 2031 is separated from the locking slot 2033-1. At this time, the force of the torsion spring 2021 will cause the clamp 2011 to close, thereby protecting the placement shaft 102.
[0055] Specifically, two connecting posts 2038 are fixed to one end of the fixing ring 2033, and the other end of the connecting post 2038 is fixed to one end of the balance testing machine 101.
[0056] The connecting post 2038 is used to fix and support the fixing ring 2033.
[0057] Specifically, a protective frame 2039 is fitted around the outside of the fixing ring 2033, and the other end of the protective frame 2039 is fixed to one end of the balance testing machine 101.
[0058] The protective frame 2039 is used to protect the fixing ring 2033.
[0059] In use, first open the clamp 2011. This moves the pressing rod 2037, causing the locking block 2031 to move. The locking block 2031 then moves the sliding strip 2035, which slides along the inner wall of the support plate 2034. The movement of the locking block 2031 applies pressure to the spring 2036, causing it to separate from the slot 2033-1. Rotating the handle 2024 causes the rotating rod 2023 to rotate, which in turn rotates the fixed plate 2032. This rotation then rotates the connecting rod 2012, which in turn rotates the protective block 2013. The rotation of the protective block 2013 applies a torsional force to the torsion spring 2021, causing the clamp 2011 to open. Then, by releasing the pressing rod 2037, the spring 2036... The rebound force of 36 causes the locking block 2031 to re-engage with the slot 2033-1, completing the limiting of the clamp 2011 after it is opened. Then, by placing the placement shaft 102 and the workpiece onto the balance testing machine 101, when it is necessary to protect the placement shaft 102 to prevent it from falling off, the pressing rod 2037 is pressed. The pressing rod 2037 moves, causing the locking block 2031 to separate from the slot 2033-1. The movement of the locking block 2031 will have a spring-like effect. When spring 2036 applies pressure, after the locking block 2031 separates from the slot 2033-1, turn handle 2024. At this time, the force of the torsion spring 2021 can close the clamp 2011, thereby fixing the placement shaft 102. Then, release the squeezing rod 2037, and the force of the spring 2036 will drive the locking block 2031 to engage with the slot 2033-1. By protecting both ends of the placement shaft 102, the flywheel is prevented from falling off.
[0060] It should be noted that the above embodiments are only used to illustrate the technical solution 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 solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
