[0006] Furthermore, the lateral clamping assembly includes two lateral clamping units with identical structures on the left and right sides but opposite directions. Each lateral clamping unit includes a slide rail and a flat clamping plate. A guide groove is opened on the bearing plate. The slide rail is slidably inserted into the guide groove. The flat clamping plate is installed on the slide rail. The slide rail is connected to the control assembly.

[0007] Furthermore, the guide groove has an opening on the second plate surface of the bearing plate, and the pin fixed on the slide rail passes through the opening;

[0008] The control assembly includes a drive shaft, a turntable, a crank, and a connecting rod; the drive shaft is rotatably and vertically inserted into a support plate, and a handle is installed on one side of the drive shaft on the first plate surface; the turntable and the crank are fixed sequentially on one side of the drive shaft on the second plate surface, the turntable is coaxial with the drive shaft, and the drive shaft is centered relative to the crank.

[0014] Compared with the prior art, the advantages of this utility model are:

[0015] This utility model provides a vibration detection device for electromechanical equipment. Through the coordinated action of the lateral and longitudinal clamping components, and a synchronous clamping mechanism driven by the same control component, it achieves four-way synchronous clamping of the electromechanical equipment. The lateral and longitudinal clamping components work together on the equipment, forming a multi-directional force structure, effectively preventing instrument displacement or loosening caused by equipment vibration, thus improving the accuracy and reliability of vibration detection. Synchronous lateral and longitudinal clamping is achieved through a single control component (drive shaft, turntable, crank, and connecting rod mechanism). Users only need to turn the handle to clamp or release, significantly improving operational efficiency.

Detailed Implementation

[0019] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0020] like Figure 1 , Figure 2 As shown: A vibration detection device for electromechanical equipment includes a support plate 1. A vibration analyzer 2 and a displacement sensor 3 are arranged on one side of the first plate surface of the support plate 1. A transverse clamping assembly and a longitudinal clamping assembly are arranged on one side of the second plate surface of the support plate 1. The clamping ranges of the transverse clamping assembly and the longitudinal clamping assembly overlap, so that the transverse clamping assembly and the longitudinal clamping assembly can work together on the electromechanical equipment. The transverse clamping assembly and the longitudinal clamping assembly are driven to move synchronously by the same control assembly.

[0021] The longitudinal clamping assembly includes two longitudinal clamping units with the same structure but opposite directions. Each longitudinal clamping unit includes an L-shaped clamping plate 4, a push-pull slider 5, and two guide rails 6. The two guide rails 6 are fixed on the second plate surface of the bearing plate 1. The vertical plate of the L-shaped clamping plate 4 is slidably nested in the groove between the two guide rails 6, which restricts the vertical linear sliding of the L-shaped clamping plate 4 and prevents it from shifting laterally. The push-pull slider 5 is slidably clamped on the two guide rails 6 and is fixedly connected to the vertical plate of the L-shaped clamping plate 4. The push-pull slider 5 is connected to the control assembly.

[0022] Specifically, a retaining strip can be provided on the outer side of the guide rail 6, and a slot can be provided on the push-pull slider 5 to slide and engage with the retaining strip. The slot of the push-pull slider 5 engages with the retaining strip of the guide rail 6 to restrict the movement of the push-pull slider 5 in a direction perpendicular to the surface of the bearing plate 1.

[0023] The transverse clamping assembly includes two transverse clamping units with the same structure on the left and right sides but opposite directions. The transverse clamping unit includes a slide rail 7 and a flat clamping plate 8. The bearing plate 1 has a guide groove 1.1. The slide rail 7 is slidably inserted into the guide groove 1.1. The flat clamping plate 8 is installed on the slide rail 7. The slide rail 7 is connected to the control assembly.

[0024] The guide groove 1.1 has an opening on the second plate surface of the bearing plate 1, and the pin 10 fixed on the slide rail 7 passes through the opening; a retaining strip is also provided in the guide groove 1.1, and a retaining groove is provided on the slide rail 7 to slide and fit with the retaining strip. The retaining groove of the slide rail 7 engages with the retaining strip on the guide groove 1.1 to prevent the slide rail 7 from disengaging from the opening of the guide groove 1.1.

[0025] The control assembly includes a drive shaft 11, a turntable 12, a crank 13, and a connecting rod 14. The drive shaft 11 is rotatably and vertically inserted into the support plate 1, and a handle 15 is installed on one side of the drive shaft 11 on the first plate surface. The turntable 12 and the crank 13 are fixed sequentially on one side of the drive shaft 11 on the second plate surface. The turntable 12 is coaxial with the drive shaft 11, and the drive shaft 11 is centered relative to the crank 13.

[0026] The two ends of the crank 13 are connected to the push-pull sliders 5 in the upper and lower longitudinal clamping units through the connecting rod 14 respectively; the two ends of the connecting rod 14 are hinged to the push-pull sliders 5 and the crank 13 respectively, and when the crank 13 rotates, it pushes the push-pull sliders 5 to move through the connecting rod 14.

[0027] The turntable 12 has two arc-shaped through slots 12.1 that are symmetrical about its center. The pins 10 in the two horizontal clamping units are located in the two arc-shaped through slots 12.1 respectively. When the turntable 12 rotates, the distance from each point of the arc-shaped through slot 12.1 to the center of the turntable 12 is different. Therefore, the arc-shaped through slot 12.1 pushes the pins 10 closer to or away from the center of the turntable 12, and thus moves the slide rail 7.

[0028] On the second plate surface of the bearing plate 1, an arc-shaped clamping plate 16 is provided around the turntable 12. The arc-shaped clamping plate 16 supports the turntable 12 in the circumferential direction and resists the reaction force of the slide rail 7 and the pin 10.

[0029] The slide rail 7 has screw holes 7.1 spaced along its length. The flat clamp plate 8 is provided with a connecting seat 8.1. The flat clamp plate 8 is fixed to the slide rail 7 by screwing the bolts 9 on the connecting seat 8.1 into the screw holes 7.1. According to the external dimensions of the electromechanical equipment, the position of the flat clamp plate 8 on the slide rail 7 is adjusted by the bolts 9 to adapt to equipment of different widths.

[0030] The handle 15 has an upper positioning hole, and the first plate surface of the support plate 1 has a lower positioning hole. It also includes a positioning pin 17, which is inserted into the upper positioning hole and the lower positioning hole to restrict the rotation of the handle 15. The positioning pin 17 is inserted into the positioning holes of the handle 15 and the support plate 1 to prevent the handle 15 from rotating back and to ensure a stable clamping state.

[0031] The mechanical linkage between the lateral and longitudinal clamping components is achieved through a single control unit. When the handle 15 is turned, the drive shaft 11 drives the turntable 12 and crank 13 to rotate synchronously. The crank 13 pushes the upper and lower sliding blocks 5 through the connecting rod 14, realizing the synchronous opening and closing of the longitudinal clamping unit; at the same time, the arc-shaped through groove 12.1 on the turntable 12 pushes the pin 10, causing the slide rail 7 to slide within the guide groove 1.1, realizing the synchronous movement of the lateral clamping unit. This structure ensures that the four-way clamping force is evenly applied to the electromechanical equipment, forming a stable multi-point clamping, effectively resisting displacement or loosening caused by vibration.

[0032] The vibration analyzer 2 has a built-in accelerometer that collects vibration signals. After amplification and filtering, the signals are converted into digital signals. Frequency and amplitude features are extracted using algorithms such as FFT. The displacement sensor 3 uses the eddy current effect to generate a high-frequency magnetic field. When a metal target approaches, the eddy current changes, or the time difference of laser reflection, to measure the minute displacement changes between the object and the probe, and outputs an electrical signal. Both the vibration analyzer 2 and the displacement sensor 3 can be selected according to the actual situation. For example, the vibration analyzer 2 can be a Fluke-810, and the displacement sensor 3 can be an EDM-30. The vibration analyzer 2 and the displacement sensor 3 are existing technologies in this field, so they will not be described in detail here.

[0033] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
