[0019] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0020] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0022] Please see Figs. 1-3 As shown, a workbench vibration detection device and its machining center include a fixed base plate 1 for rigid connection to the side of the workbench of the machining center; fixed clamping plates 4 are fixedly fixed at intervals on one side of the fixed base plate 1; a stepped square shaft 6 is rotatably inserted into the two fixed clamping plates 4; a swing plate 10 is non-rotatably sleeved on the stepped square shaft 6, so that the stepped square shaft 6 and the swing plate 10 rotate together to change the angle; an alignment groove 8 is provided on the swing plate 10; a locking groove 7 is provided on the stepped square shaft 6; an elastic plate 9 is inserted into the locking groove 7 and the alignment groove 8, so that the swing plate 10 and the stepped square shaft 6 become elastic in the rotation around the fixed clamping plate 4, so as to resist the gravity of the swing plate 10 and keep it suspended. Then, with the vibration of the workbench, the swing amplitude of the end of the swing plate 10 is amplified, thereby alerting the operator that the vibration amplitude of the workbench is too large.

[0023] The protective cover 3, which is used to prevent collisions, is detachably connected to the fixed base plate 1 using fasteners 2, resulting in a longer service life and greater safety.

[0024] A metal plate 11 is symmetrically slotted at one end of the swing plate 10 away from the stepped square axis 6; a number of proximity sensors 12 are inserted into the protective cover 3 corresponding to the openings of the metal plate 11. The up-and-down movement amplitude of the bidirectional metal plate 11 is detected by the multiple proximity sensors 12, so that the vibration amplitude of the worktable can be accurately detected, thereby realizing the electrical transmission of the vibration amplitude.

[0025] By providing a clearance groove 5 within the fixed clamping plate 4 to allow for the deformation of the elastic plate 9, the elastic plate 9 made of metal has space to deform, and the vertical vibration amplitude of the stepped square shaft 6 can be amplified and transmitted through deformation.

[0026] The three oscillating plates 10 connected end to end allow for further amplification of the vibration amplitude of the worktable, thereby enabling the detection of smaller vibration amplitudes for improving the worktable design; the oscillating plates 10 are made of rigid plastic, resulting in low weight and less interference due to their own weight.
