[0033] The vibration measuring device 100 includes a frame 110 , a support member 120 , a pressure member 130 , and at least two detection members 140 ;

[0034] Among them, the support member 120 is telescopically and rotatably connected to the frame 110 and is used to support the product, the pressure member 130 is telescopically connected to the frame 110 and is used to apply pressure to the product, at least two detection members 140 are telescopically connected to the frame 110 and are used to support the side wall of the product, and at least two detection members 140 are used to be arranged at intervals along the rotation circumference of the support member 120.

[0035] During operation, the support member 120, the pressure member 130 and the detection member 140 are all connected to the frame 110, which provides fixed support for each component and ensures the relative position stability between the components. The support member 120, the pressure member 130 and the detection member 140 can all be extended and retracted relative to the frame 110 to adjust the detection position or pressure intensity. The support member 120 can also rotate relative to the frame 110 to drive the product to rotate, thereby further improving the detection accuracy.

[0036] refer to Figure 1 and Figure 2 The frame 110 includes a base 112 and an extension frame 114, the bottom end of the extension frame 114 is connected to the top surface of the base 112, the support member 120 is telescopically and rotatably connected to the base 112, the pressure member 130 is telescopically connected to the extension frame 114, and at least two detection members 140 are telescopically connected to the base 112 and / or the extension frame 114.

[0037] It is worth noting that the detection member 140 can be connected to the base 112 or the extension frame 114 , and there is no limitation on the specific installation position of the detection member 140 .

[0038] Furthermore, the base 112 extends in the front-to-back direction, thus having a front end and a rear end. When working, a worker is typically located at the front side of the base 112, that is, the worker is typically closer to the front end of the base 112 than to the rear end of the base 112. The extension frame 114 extends in the vertical direction, and the bottom end of the extension frame 114 is connected to a position near the rear end of the base 112, so that sufficient working space is reserved on the upper side of the base 112 near the front end.

[0039] In this embodiment, there are three groups of detection members 140 . The distance between the detection member 140 in the middle and the two detection members 140 on both sides is equal. The detection member 140 in the middle is connected to the extension frame 114 , and the two detection members 140 on both sides are connected to the base 112 .

[0040] refer to Figure 1 and Figure 2 In order to improve the guiding effect of the pressure member 130 and ensure the movement stability of the pressure member 130 during the pressure application process of multiple products, the frame 110 can also include a guide rail 116. The extension direction of the guide rail 116 is consistent with the pressure direction of the pressure member 130, and the guide rail 116 slides in conjunction with the pressure member 130.

[0041] In this embodiment, the pressure member 130 applies pressure to the top surface of the product. That is, the pressure applied by the pressure member 130 can be considered to be from top to bottom, while the extension direction of the guide rails 116 can be understood as being from top to bottom. There are two guide rails 116, each disposed on either side of the front end of the extension frame 114. Of course, in other embodiments of the present invention, the number of guide rails 116 can be one, three, five, etc., and the specific number of guide rails 116 is not limited.

[0042] refer to Figure 1 and Figure 2Detection member 140 includes a third telescopic power source 141 and a vibrating head 142. Third telescopic power source 141 is mounted on base 112 or extension frame 114. Vibrating head 142 faces the product and is used to abut against the product's sidewall. During operation, third telescopic power source 141 provides power to move vibrating head 142 toward or away from the product.

[0043] In this embodiment, there are three groups of third telescopic power sources 141 and vibration measuring heads 142. The third telescopic power source 141 located in the middle is connected to the extension frame 114, and the two third telescopic power sources 141 located on both sides are connected to the base 112. The direction of the vibration measuring head 142 is consistent with the radial direction of the product.

[0044] It is worth noting that the third telescopic power source 141 can specifically be a telescopic air cylinder, a telescopic electric cylinder or a telescopic hydraulic cylinder, and there is no limitation on its specific power form.

[0045] Furthermore, to facilitate the operation of the staff, the third telescopic power source 141 and the extension frame 114 can be positioned closer to the rear end of the base 112 relative to the front end of the base 112 , thereby reserving sufficient operating space on the upper side of the front end of the base 112 .

[0046] refer to Figure 1 and Figure 2 The support member 120 includes a rotating disk 121, a support plate 122 and a first telescopic power source 123. The first telescopic power source 123 is installed on the frame 110. The support plate 122 is transmission-connected to the first telescopic power source 123. The rotating disk 121 is connected to the support plate 122 and protrudes from the top surface of the support plate 122. The rotating disk 121 is used to support the bottom surface of the product.

[0047] In operation, the first telescopic power source 123 provides power to drive the support plate 122 to telescope. The rotating disk 121 moves synchronously with the support plate 122, thereby adjusting the height of the product. The rotating disk 121 can rotate relative to the support plate 122 to drive synchronous rotation of the product, facilitating the vibration head 142 to detect different positions of the product around the circumference.

[0048] In this embodiment, the support member 120 further includes a rotational power source 124, which is mounted on the frame 110. The rotating disk 121 is connected to the rotational power source 124 via a synchronous belt 125. Specifically, the rotational power source 124 is mounted on the base 112, and the output shaft of the rotational power source 124 and the bottom of the rotating disk 121 are driven by the synchronous belt 125.

[0049] At the same time, in order to facilitate the rotation of the rotating disk 121 and the movement of the support plate 122 in the height direction, the rotating disk 121 itself can be made into a telescopic structure. When driven by the support plate 122, the rotating disk 121 can be extended or shortened accordingly. Specifically, the rotating disk 121 can be a two-stage telescopic structure or a three-stage telescopic structure, and the specific number of telescopic stages of the rotating disk 121 is not limited.

[0050] It is worth noting that the first telescopic power source 123 can be a telescopic air cylinder, a telescopic electric cylinder or a telescopic hydraulic cylinder, and there is no limitation on its specific power form; the rotary power source 124 can be a rotary air cylinder, a rotary electric cylinder or a rotary hydraulic cylinder, and there is no limitation on its specific power form.

[0052] In this embodiment, there are two arc-shaped splints 126 , which are symmetrically arranged. Of course, in other embodiments of the present invention, the number of arc-shaped splints 126 can also be one, three, five, etc., and the specific number is not limited.

[0053] Optionally, the pressure member 130 includes a second telescopic power source 131 and a squeeze block 132 connected to each other. The second telescopic power source 131 is mounted on the frame 110 , and the squeeze block 132 is used to press against the top surface of the product. Specifically, the second telescopic power source 131 is mounted on the extension frame 114 .

[0054] During operation, the second telescopic power source 131 is used to provide power to drive the squeezing block 132 to move closer to or away from the product, and when the squeezing block 132 contacts the product, it can provide a certain squeezing force to the product, thereby achieving a pressure operation on the product.

[0055] It is worth noting that the second telescopic power source 131 can specifically be a telescopic air cylinder, a telescopic electric cylinder or a telescopic hydraulic cylinder, and there is no limitation on its specific power form.

[0056] Furthermore, in order to improve the pressure stability of the extrusion block 132, the pressure member 130 may further include a sliding block 133 connected to the extrusion block 132 and slidingly engaged with the frame 110. Specifically, the sliding block 133 slides with the guide rail 116 on the extension frame 114.

[0057] In summary, the vibration measuring device 100 provided in the embodiment of the present invention has at least the following advantages:

[0058] The vibration measuring device 100 uses the frame 110 to provide fixed support for each component and ensure the relative position stability between the components.
