Description

Technical Field

[0001] This utility model relates to the field of vibration transmitter testing technology, and in particular to a testing device for vibration transmitters. Background Technology

[0002] A vibration transmitter is a device used to measure vibrations in mechanical equipment or structures. It is commonly used to monitor the operating status of machines, especially in industrial equipment, to predict equipment failures or anomalies by detecting changes in vibration. These transmitters convert vibration signals into electrical signals, which are then transmitted to a monitoring system for analysis. Common applications of vibration transmitters include equipment monitoring, fault diagnosis, and preventative maintenance. Vibration transmitters typically feature high sensitivity and strong anti-interference capabilities, enabling them to operate stably in harsh environments. They are widely used in industries such as petrochemicals, power generation, metallurgy, and mining.

[0003] In the prior art, vibration transmitters need to be tested for their vibration resistance during the production process to test their tolerance to high-intensity vibration environments. However, existing vibration transmitter testing devices are not stable enough in fixing the vibration transmitter, causing the transmitter to shift or loosen during testing, resulting in inaccurate test results. Therefore, this application proposes a vibration transmitter testing device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing vibration transmitter anti-vibration testing devices, which are not stable enough in fixing the vibration transmitter, causing the vibration transmitter to shift or loosen during testing, resulting in inaccurate test results. Therefore, this invention proposes a vibration transmitter testing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A testing apparatus for a vibration transmitter includes a base and a vibration transmitter body. The testing apparatus further includes:

[0007] The base has four fixing rods, and the bottom ends of the four fixing rods are all fixedly installed on the top of the base.

[0008] The vibration table is respectively set at the top of four fixed rods. The bottom of the vibration table has four sliding grooves. A slider is fixedly installed at the top of each of the four fixed rods. The slider is slidably connected in the corresponding sliding groove. A spring is fixedly installed on the left inner wall and the right inner wall of the sliding groove. The ends of two springs that are close to each other are fixedly installed on the corresponding sliders.

[0009] The vibration transmitter body is placed on top of the vibration table, and an adjustable vibrator is fixedly installed at the bottom of the vibration table.

[0010] The main clamping assembly includes: two dual-axis lead screws, two moving rods, two frames, and two clamping seats. Two sliding holes are opened on the vibration table. The right end of the dual-axis lead screw passes through the left side of the vibration table and is rotatably connected to the right inner wall of the right sliding hole. The two moving rods are threaded onto the dual-axis lead screws. The top end of the moving rod passes through the corresponding sliding hole and is slidably connected to the inner wall of the sliding hole. The bottom of the frame is fixedly installed on the top end of the corresponding moving rod. The two clamping seats are fixedly installed on the opposite sides of the two frames, and the two clamping seats clamp the body of the vibration transmitter.

[0011] The auxiliary clamping components are respectively mounted on the two frames and cooperate with the main body of the vibration transmitter.

[0012] As a preferred embodiment of this utility model, anti-slip pads are fixedly installed at the four corners of the bottom of the base.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example

[0029] Reference Figures 1-4 A testing device for a vibration transmitter includes a base 1 and a vibration transmitter body 20. The testing device also includes:

[0030] There are four fixing rods 5, and the bottom ends of the four fixing rods 5 are fixedly installed on the top of the base 1.

[0031] A vibration table 6 is set at the top of four fixed rods 5. The bottom of the vibration table 6 is provided with four sliding grooves 7. A slider 8 is fixedly installed at the top of each of the four fixed rods 5. The slider 8 is slidably connected in the corresponding sliding groove 7. A spring 9 is fixedly installed on the left inner wall and the right inner wall of the sliding groove 7. The ends of the two springs 9 that are close to each other are fixedly installed on the corresponding slider 8.

[0032] The vibration transmitter body 20 is placed on top of the vibration table 6, and an adjustable vibrator 10 is fixedly installed at the bottom of the vibration table 6.

[0033] The main clamping assembly includes two dual-axis lead screws 12, two moving rods 13, two frames 14, and two clamps 15. The vibration table 6 has two sliding holes 11. The right end of the dual-axis lead screw 12 passes through the left side of the vibration table 6 and is rotatably connected to the right inner wall of the right sliding hole 11. The two moving rods 13 are threaded onto the dual-axis lead screws 12. The top end of the moving rod 13 passes through the corresponding sliding hole 11 and is slidably connected to the inner wall of the sliding hole 11. The bottom of the frame 14 is fixedly installed on the top end of the corresponding moving rod 13. The two clamps 15 are fixedly installed on the opposite sides of the two frames 14 and the opposite sides of the two frames 14. Both clamps 15 are clamped to the vibration transmitter body 20.

[0034] The auxiliary clamping components are respectively set on the two frames 14 and cooperate with the vibration transmitter body 20.

[0035] To solve the problem of unstable clamping of the vibration transmitter body 20, such as Figure 3 As shown, the vibration transmitter body 20 is placed on top of the vibration table 6. Then, the dual-axis lead screw 12 is rotated, and the screw connection between the dual-axis lead screw 12 and the two moving rods 13 is engaged. This allows the two frames 14 and the two clamps 15 to move closer to each other and achieve rapid and stable clamping of the vibration transmitter body 20. At this time, the adjustable vibrator 10 is activated, which can drive the vibration table 6 and the vibration transmitter body 20 to vibrate stably. Here, the sliding limit engagement between the slider 8 and the slide groove 7, combined with the elastic reset characteristic of the spring 9, can achieve stable vibration support for the vibration table 6 and the vibration transmitter body 20, ensuring the vibration resistance test effect of the vibration transmitter body 20.

[0036] As a preferred embodiment of this utility model, anti-slip pads 2 are fixedly installed at the four corners of the bottom of the base 1. The placement stability of the base 1 can be improved by setting the anti-slip pads 2.

[0037] As a preferred embodiment of this utility model, a controller 3 is fixedly installed on the top of the base 1. By setting the controller 3, the vibration frequency and intensity of the adjustable vibrator 10 can be adjusted and controlled.

[0038] As a preferred embodiment of this utility model, a display 4 is fixedly installed on the top of the base 1, and the vibration output data of the adjustable vibrator 10 can be displayed by setting the display 4.

[0039] As a preferred embodiment of this utility model, the auxiliary clamping assembly includes two screws 16, two nuts 17, four connecting rods 18, and four clamping blocks 19. The ends of the two screws 16, close to each other, pass through two frames 14 and are rotatably connected to the inner walls of the frames 14. The nuts 17 are threaded onto the corresponding screws 16. The front and rear sides of the nuts 17 are fixedly installed at the close ends of the corresponding two connecting rods 18. The clamping blocks 19 are fixedly installed at one end of the corresponding connecting rod 18, and one end of the clamping block 19 passes through the clamping seat 15 and is subjected to vibration. The transmitter body 20 is in contact with each other. In order to improve the clamping stability of the vibration transmitter body 20, by rotating the two screws 16 and engaging the threaded connection between the screws 16 and the nuts 17, the two connecting rods 18 on the left and the two clamping blocks 19 on the right can be driven to move closer to each other. At this time, the vibration transmitter body 20 is clamped by the four clamping blocks 19, which can improve the clamping stability of the vibration transmitter body 20, thereby maximizing the vibration resistance test effect of the vibration transmitter body 20.

[0040] As a preferred embodiment of this utility model, the clamping base 15 has two through holes, and one end of the clamping block 19 passes through the corresponding through hole and slides in contact with the inner wall of the through hole. By opening the through hole, the clamping block 19 can be stably limited and supported in sliding.

[0041] It should be noted that the specific models of controller 3, display 4, adjustable vibrator 10, and vibration transmitter body 20 used can be selected by those skilled in the art. Furthermore, the controller 3, display 4, adjustable vibrator 10, and vibration transmitter body 20 mentioned above are all existing technologies, and this solution will not elaborate on them.

[0042] The working principle of this utility model is as follows: In use, first connect the controller 3, display 4, adjustable vibrator 10, and vibration transmitter body 20 to an external power source. Then, place the vibration transmitter body 20 on top of the vibration table 6. Rotate the dual-axis lead screw 12, and through the threaded connection between the dual-axis lead screw 12 and the two moving rods 13, drive the two frames 14 and two clamps 15 closer together, achieving rapid and stable clamping of the vibration transmitter body 20. At this point, starting the adjustable vibrator 10 will drive the vibration table 6 and the vibration transmitter body 20 to vibrate stably. This is achieved through the sliding limit mechanism between the slider 8 and the slide groove 7. Then, by combining the elastic restoring characteristics of the spring 9, stable vibration support can be achieved for the vibration table 6 and the vibration transmitter body 20, ensuring the vibration test effect of the vibration transmitter body 20. At this time, by rotating the two screws 16 and connecting them with the nuts 17 through the threaded connection, the two connecting rods 18 on the left and the two clamping blocks 19 on the right can be driven to move closer to each other. At this time, the clamping of the vibration transmitter body 20 by the four clamping blocks 19 can improve the clamping stability of the vibration transmitter body 20, thereby maximizing the vibration test effect of the vibration transmitter body 20.
