Description

Technical Field

[0001] This utility model relates to the field of acceleration sensor technology, specifically to an acceleration sensor mounting structure. Background Technology

[0002] A triaxial accelerometer is a sensor capable of simultaneously measuring acceleration along three axes (typically x, y, and z). Based on Newton's second law, when the sensor is subjected to acceleration, the internal mass will generate a corresponding force. By detecting changes in the displacement, stress, or strain of the mass, the acceleration is converted into an electrical signal for measurement using principles such as piezoelectricity, piezoresistive effect, or capacitance change. When using a triaxial accelerometer to measure bearings, the sensor is typically fixed to the bearing housing, and the connection between the sensor and the housing is usually achieved using bolts or magnetic attachment.

[0003] Magnetic connection utilizes the magnetism of the magnetic base to attach the sensor to the bearing housing, offering advantages in ease of installation and disassembly. However, during installation, the X-axis of the triaxial accelerometer body must be parallel to the axis of the bearing on the bearing housing, and the Y-axis and Z-axis must be parallel to the horizontal radial line and vertical diameter line of the bearing on the bearing housing, respectively. While magnetic connection is convenient, it requires continuous fine-tuning by the operator to ensure the correct orientation of the X, Y, and Z axes. (Bolt connections typically use two bolts for positioning, eliminating the need for fine-tuning, but their installation and disassembly are not as convenient as magnetic connection.) Therefore, a different installation structure for the accelerometer is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an installation structure for an accelerometer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an accelerometer mounting structure, comprising a triaxial accelerometer body, a magnetic base at the bottom of the triaxial accelerometer body, a bearing seat at the bottom of the magnetic base, the magnetic base being attracted to the upper end of the bearing seat, a connector on one side wall of the triaxial accelerometer body, and a positioning mechanism on the other side wall of the triaxial accelerometer body. The positioning mechanism consists of a mounting plate and a positioning plate. The mounting plate is fixedly connected to the side wall of the magnetic base. A sliding groove is formed at the bottom of the mounting plate. The sliding groove is a rectangular groove, and the positioning plate is slidably inserted into the sliding groove. An adjustment mechanism acting on the positioning plate is also provided in the sliding groove.

[0006] As a further preferred embodiment of this technical solution, the positioning plate and the sidewalls of the triaxial accelerometer body that are close to each other are parallel to each other.

[0007] As a further preferred embodiment of this technical solution, the adjusting mechanism consists of an adjusting threaded rod and an adjusting element. The adjusting threaded rod is rotatably connected to the top wall of the inner cavity of the slide groove. The positioning plate is threaded onto the outer surface of the adjusting threaded rod. The upper end of the adjusting threaded rod extends to the top of the mounting plate. The adjusting element is fixedly connected to the extended end of the adjusting threaded rod.

[0008] As a further preferred embodiment of this technical solution, the outer wall of the adjusting member is provided with multiple anti-slip seams, and the multiple anti-slip seams are arranged in a circular array with the axis of the adjusting member as the center.

[0009] As a further preferred embodiment of this technical solution, connecting plates are fixedly connected to both sides of the mounting plate, and the connecting plates are fixedly connected to the outer shell of the triaxial accelerometer body by a number of fixing screws.

[0010] As a further preferred embodiment of this technical solution, a connecting threaded rod is fixedly connected to the upper center of the magnetic base, and a threaded hole is opened at the bottom of the triaxial accelerometer body, with the connecting threaded rod threadedly engaged with the threaded hole.

[0012] This utility model provides an installation structure for an accelerometer, which has the following advantages:

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, an accelerometer mounting structure includes a triaxial accelerometer body 1. A magnetic base 13 is provided at the bottom of the triaxial accelerometer body 1, and a bearing seat 4 is provided at the bottom of the magnetic base 13. The magnetic base 13 is attached to the upper end of the bearing seat 4. A connector 2 is provided on one side wall of the triaxial accelerometer body 1, and a positioning mechanism is provided on the other side wall of the triaxial accelerometer body 1. The positioning mechanism consists of a mounting plate 5 and a positioning plate 6. The mounting plate 5 is fixedly connected to the side wall of the magnetic base 13. A sliding groove 7 is provided at the bottom of the mounting plate 5. The sliding groove 7 is a rectangular groove, and the positioning plate 6 is slidably inserted into the sliding groove 7. An adjustment mechanism acting on the positioning plate 6 is also provided in the sliding groove 7.

[0021] The positioning plate 6 and the sidewalls of the triaxial accelerometer body 1 are parallel to each other.

[0022] The adjusting mechanism consists of an adjusting threaded rod 8 and an adjusting component 9. The adjusting threaded rod 8 is rotatably connected to the top wall of the inner cavity of the slide groove 7. The positioning plate 6 is threaded onto the outer surface of the adjusting threaded rod 8. The upper end of the adjusting threaded rod 8 extends to the top of the mounting plate 5. The extended end of the adjusting threaded rod 8 is fixedly connected to the adjusting component 9. Multiple anti-slip seams 10 are provided on the outer wall of the adjusting component 9. The multiple anti-slip seams 10 are arranged in a circular array with the axis of the adjusting component 9 as the center.

[0023] In use, rotating the adjusting component 9 drives the adjusting threaded rod 8 to rotate. Since the slide groove 7 is a rectangular groove, the positioning plate 6 can only slide within the slide groove 7. When the adjusting threaded rod 8 rotates, the positioning plate 6 will slide along the direction of the slide groove 7. By controlling the positioning plate 6 to slide downward, it can extend out of the slide groove 7.

[0024] Among them, the mounting plate 5 is fixedly connected to the two sides of the mounting plate 11 respectively, and the connecting plate 11 is fixedly connected to the outer shell of the triaxial accelerometer body 1 by a number of fixing screws 12.

[0025] Among them, a connecting threaded rod 14 is fixedly connected to the upper center of the magnetic base 13, and a threaded hole 15 is opened at the bottom of the triaxial accelerometer body 1, and the connecting threaded rod 14 is threadedly engaged with the threaded hole 15.

[0026] By connecting the threaded rod 14 and the threaded hole 15 with a threaded engagement, the magnetic base 13 can be fixedly connected to the triaxial accelerometer body 1.

[0027] The outer wall of the triaxial accelerometer body 1 is marked with a mark. Figure 3 .

[0028] This setup allows staff to quickly identify the X, Y, and Z axes of the triaxial accelerometer body 1.

[0029] This utility model provides an installation structure for an accelerometer, the specific working principle of which is as follows:

[0030] In use, the bearing housing 4 is made of ferromagnetic material and can be attracted to the magnetic seat 13. Through the attraction between the magnetic seat 13 and the bearing housing 4, the triaxial accelerometer body 1 can be fixed on the bearing housing 4. Then, rotating the adjusting component 9 drives the adjusting threaded rod 8 to rotate. Since the slide groove 7 is a rectangular groove, the positioning plate 6 can only slide within the slide groove 7. When the adjusting threaded rod 8 rotates, the positioning plate 6 will slide along the direction of the slide groove 7. Controlling the positioning plate 6 to slide downward so that it extends out of the slide groove 7, the part of the positioning plate 6 extending out of the slide groove 7 abuts against the end side wall of the bearing housing 4. Because the positioning plate 6 and the triaxial accelerometer body 1 are attached to the bearing housing 4, the positioning plate 6 and the bearing housing 4 are attached to the bearing housing 4. With the sidewalls of the three-axis accelerometer body 1 close to each other and parallel to each other, the sidewall of the three-axis accelerometer body 1 can be made parallel to the sidewall of the bearing seat 4. This makes the X-axis of the three-axis accelerometer body 1 parallel to the axis of the bearing on the bearing seat 4, and the Y-axis and Z-axis of the three-axis accelerometer body 1 parallel to the horizontal radial line and vertical diameter line of the bearing on the bearing seat 4, respectively. This allows for quick positioning of the three-axis accelerometer body 1. When the three-axis accelerometer body 1 is not in use, the positioning plate 6 can be retracted into the slide groove 7 by rotating the adjusting member 9 in the opposite direction, so as to avoid the positioning plate 6 affecting the carrying of the three-axis accelerometer body 1.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
