Description

Technical Field

[0001] This utility model relates to an adjustable vibration sensor debugging device, specifically an adjustable vibration sensor debugging device, belonging to the field of vibration sensor debugging technology. Background Technology

[0002] Vibration sensors are a key component in testing technology. Their main function is to receive mechanical quantities and convert them into proportional electrical quantities. Because they are also electromechanical conversion devices, they are sometimes called transducers or vibration pickups. Vibration sensors do not directly convert the original mechanical quantity to be measured into an electrical quantity. Instead, the original mechanical quantity is used as the input to the vibration sensor, which is then received by the mechanical receiving section to form another mechanical quantity suitable for conversion. Finally, the electromechanical conversion section converts this mechanical quantity into an electrical quantity. Therefore, the performance of a sensor is determined by the performance of its mechanical receiving section and its electromechanical conversion section.

[0003] In the prior art, the field of semi-automatic high-temperature piezoelectric vibration sensor debugging technology is authorized by announcement number CN117817309A. Specifically, it is a semi-automatic high-temperature piezoelectric vibration sensor debugging device, including a base, a back plate fixedly installed on the base, a worktable mechanism fixedly installed at the lower end of the back plate, and an upper slider provided above the worktable mechanism. The upper slider is fixedly connected to the piston rod of the first cylinder.

[0004] In existing semi-automatic high-temperature piezoelectric vibration sensor debugging equipment, as shown in the invention patent with publication number CN117817309A, the clamping and concentricity alignment of vibration sensor components are achieved through the cooperation of a platform, a shaping fixture, and a cylinder. However, the shaping fixture in this structure only has a horizontal clamping function, and the product angle is fixed after clamping. It is impossible to make fine adjustments to the tilt angle according to actual assembly requirements. As a result, when the vibration sensor components are tilted, it is impossible to correct them, thus reducing the practicality of the vibration sensor debugging device. Utility Model Content

[0020] This utility model provides a calibration device for an azimuth-adjustable vibration sensor.

[0022] Example 2, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The adjusting plate 3 has an installation groove 9 on one side. The clamping plate 4 is slidably set in the installation groove 9. The inclined track plate 5 is located inside the installation groove 9. The cylinder 7 is fixedly set on the inner wall of the installation groove 9. The trapezoidal block 6 is slidably set in the installation groove 9.

[0023] Example 3, please refer to Figure 3 and Figure 4 Two track rods 10 are fixedly connected to one side of the inclined track plate 5. The trapezoidal block 6 has a track groove 11 at the corresponding position of the track rod 10, and the track rod 10 is slidably set in the corresponding track groove 11.

[0024] Example 4, please refer to Figure 3 and Figure 5 Each of the two clamping plates 4 is rotatably connected to abutment plates 12 on one side facing each other. An L-groove is opened inside the clamping plate 4. A connecting rod 13 is rotatably connected to the inner wall of the L-groove. A bevel gear 14 is fixedly connected to one end of the connecting rod 13 and the side wall of the abutment plate 12. The two bevel gears 14 are meshed with each other. A linkage mechanism is provided on the adjusting plate 3 to drive the two connecting rods 13 to rotate together.

[0025] Example 5, please refer to Figure 3 and Figure 5 The linkage mechanism includes a hexagonal rod 15 and two sliding sleeves 16. The hexagonal rod 15 is rotatably connected between the two end faces of the mounting groove 9. The sliding sleeves 16 are slidably sleeved on the outside of the hexagonal rod 15. The clamping plate 4 has a through-slot at the corresponding position of the sliding sleeve 16. The sliding sleeve 16 is rotatably connected in the corresponding slot. The outer side of the sliding sleeve 16 and the end of the connecting rod 13 away from the first bevel gear 14 are both fixedly sleeved with a second bevel gear 17. The two second bevel gears 17 mesh with each other. Specifically, to improve the angle adjustment accuracy, a backlash compensation table can be preset in the controller. Based on the rotation direction and historical position, the backlash error can be automatically compensated, thereby reducing the problems of tooth flank clearance and meshing lag between bevel gear 14 and bevel gear 27 during transmission.

[0026] Example 6, please refer to Figure 3 and Figure 5 A dual-axis motor 18 is installed on the inner wall of the mounting groove 9. The hexagonal rod 15 includes two long rods. One end of the two long rods facing each other is fixedly connected to the output shafts at both ends of the dual-axis motor 18, and the other end of the two long rods is fixedly connected to the inner walls on both sides of the mounting groove 9.

[0027] Example 7, please refer to Figure 1 , Figure 2 and Figure 3 A servo motor 19 is installed on the main body 1 of the device, and the output shaft of the servo motor 19 is fixedly connected to the center of the shaft on one side of the adjustment plate 3. Specifically, both the servo motor 19 and the dual-axis motor 18 are electrically connected to the controller, which is installed on the device body 1. Since the controller is an existing technology device, it will not be described in detail in this application. The controller is electrically connected to the power supply. The models of the controller, servo motor 19 and dual-axis motor 18 are not limited, and the appropriate equipment shall prevail.

[0028] Example 8, please refer to Figure 1 The device body 1 has a base plate 24 at the bottom, a back plate 20 on the base plate 24, and an electro-optical mechanism 21, a display mechanism 22 and a lifting mechanism 23 on the back plate 20. Specifically, after the vibration sensor components are clamped between the two contact plates 12, the system enters the automatic alignment process; initial image acquisition and attitude recognition: the electro-optical mechanism 21 on the device body 1 acquires high-resolution images of the product, and the image data is transmitted to the image processing module through the controller. This module identifies the outer contour axis of the product based on the edge detection algorithm, compares it with the preset standard axis, and calculates the current tilt angle.

[0029] The back plate 20, which is equipped with an electro-optical mechanism 21, a display mechanism 22, and a lifting mechanism 23, are all existing technologies and structures. This application mainly relates to the clamping of vibration sensor components. The use of structures such as inserts, magnetic rings, insert rods, and push rods adopts existing publicly available technologies. That is, the vibration sensor components are connected in series using inserts, magnetic rings, and insert rods, and the vibration sensor components and inserts are placed in the positioning groove 8. At the same time, they are clamped and fixed using the clamping plate 4. Then, the tilt angle of the sensor components is finely adjusted to make them upright. After that, the upper slider in the lifting mechanism 23 is used to squeeze, and the insert rod is pulled out and the push rod is pushed out.

[0030] Working principle: The device body 1 is equipped with an adjustment plate 3 that can rotate left and right. The adjustment plate 3 is driven by a servo motor 19 and can rotate at a certain angle in the horizontal plane. Two sets of clamping plates 4 are symmetrically arranged on the adjustment plate 3. The inner side of the clamping plate 4 is equipped with a rotating abutment plate 12. The product is clamped between the two abutment plates 12.

[0031] After the product is placed in the clamping area, the cylinder 7 drives the trapezoidal block 6 to slide. The trapezoidal block 6 cooperates with the inclined track plate 5 to drive the two clamping plates 4 to move towards each other. The contact plate 12 on the clamping plate 4 clamps the outer wall of the vibration sensor component, completing the initial fixation. At this time, if the vibration sensor component is detected to be tilted to the left or right, the servo motor 19 can be controlled to rotate the adjusting plate 3, which drives the entire clamping mechanism and the vibration sensor component to rotate left and right together to achieve tilt correction. If the vibration sensor component is tilted forward or backward, the contact plate 12 is driven to rotate, causing the product to rotate in the forward or backward direction to complete the angle adjustment.

[0032] Through the coordinated action of the adjusting plate 3 and the abutting plate 12, the product can be tilted in any direction within the space, ensuring that it is in the best posture before pressing, effectively avoiding assembly errors or parts damage caused by the non-adjustable angle of traditional fixtures.
