Abstract
Description
Technical Field
[0001] This utility model relates to the field of inertial sensor fixture technology, specifically a fixture for inertial sensor production. Background Technology
[0002] Inertial sensors are sensors used to detect and measure acceleration, tilt, impact, vibration, rotation, and multi-degree-of-freedom motion. They are important components for navigation, orientation, and motion vehicle control, and have advantages such as high precision, high reliability, strong anti-interference ability, and the ability to work in harsh environments. They can measure the motion state and attitude changes of objects in real time and accurately, and are not affected by external magnetic fields, electric fields, etc. They are used in vehicle dynamic stability control, anti-lock braking systems, vehicle airbag systems, autonomous driving, etc., which can improve vehicle safety and comfort.
[0003] Fixtures are required in the production of inertial sensors. Chinese utility model patent CN214445696U discloses a fixture for MEMS inertial sensor production, comprising a housing. A motor is installed inside the housing, and the output end of the motor is welded to the main gear of a planetary gear set. Connecting rods are inserted into the interior of the secondary gear of the planetary gear set. A first bevel gear is welded to one end of each of the two sets of connecting rods. The two sets of first bevel gears are meshed with second bevel gears. Bolt rods are inserted into the interior of each of the two sets of second bevel gears. Nuts are threaded onto the exterior of each of the two sets of bolt rods. Support rods are welded to one side of each of the two sets of nuts. Connecting blocks are welded to one end of each of the two sets of support rods. This utility model has a simple structure, is easy to use, and allows for quick sensor assembly and disassembly. It also provides a more secure sensor fixation, improving production quality and efficiency to a certain extent.
[0004] This utility model drives two sets of support rods to move closer together, so that the two sets of fixing plates will fix and limit the outside of the sensor. However, the existing fixing fixtures use mechanical clamping to fix the outside of the sensor. The clamping and releasing process is time-consuming and inefficient, and cannot be quickly fixed. At the same time, the orientation angle of the sensor cannot be adjusted in real time, making it inconvenient for workers to install. Therefore, a fixing fixture for inertial sensor production is proposed to solve the above-mentioned problems. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a fixing fixture for inertial sensor production, which has advantages such as adjustable orientation angle and rapid fixing. It solves the problems of existing fixing fixtures, which have long clamping and releasing processes, low efficiency, and inability to quickly fix the sensor. At the same time, they cannot adjust the orientation angle of the sensor in real time, making it inconvenient for workers to install the sensor.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A fixture for manufacturing inertial sensors includes a fixed platform, the inner side of which is provided with an adjustment and fixing component for adjusting the orientation angle and quick fixing.
[0008] The adjusting and fixing assembly includes a rotating column rotatably connected to the inner bottom wall of the fixed platform. A worktable is fixedly connected to the top of the rotating column. A drive motor is fixedly connected to the right side of the fixed platform. A bevel gear is fixedly connected to the output shaft of the drive motor. A bevel gear ring is fixedly connected to the outer side of the worktable. A fixed frame is fixedly connected to the top of the worktable. Cylinders are fixedly connected to the left and right sides of the fixed frame. A fixed plate is fixedly connected to the output shaft of the cylinder. Two movable rods are fixedly connected to the inner side of the fixed frame. The fixed plate is slidably connected to the movable rods.
[0009] Furthermore, a pad is adhered to the inner side of the fixing plate, and the pad is made of silicone.
[0010] Furthermore, a mounting cover is fixedly installed on the outside of the drive motor, and sound-absorbing cotton for noise reduction is adhered to the inside of the mounting cover.
[0011] Furthermore, the mounting cover has heat dissipation vents on both the front and back, and a dustproof mesh is fixedly connected to the inner side of the heat dissipation vents.
[0012] Furthermore, the bevel gear meshes with the bevel gear ring for transmission, and both the fixed table and the worktable are circular in shape.
[0013] Furthermore, a movable plate is fixedly connected to the bottom of the fixed platform, and casters are rotatably connected to the bottom of the movable plate around its perimeter.
[0014] Furthermore, a frame is fixedly connected to both the front and back of the fixed platform, and an electric push rod is fixedly connected to the top of the frame.
[0015] Furthermore, the output shaft of the electric push rod is fixedly connected to a stop block, which is an iron block.
[0016] Compared with the prior art, this utility model provides a fixed fixture for the production of inertial sensors, which has the following advantages:
[0017] 1. This inertial sensor manufacturing fixture, through the setting of an adjustable fixing component, realizes pneumatic clamping and angle adjustment functions. Specifically, two cylinders can simultaneously drive two fixing plates to slide on the outer surface of the movable rod, thereby approaching the sensor and quickly clamping it on both sides. The clamping efficiency is high, and the sensor is placed in the middle of the fixing frame. In addition, the drive motor can drive the worktable to rotate in the opposite direction of the drive motor's output shaft through the meshing transmission between the bevel gear and the bevel gear ring, thereby adjusting the sensor's orientation angle in real time for easy installation.
[0018] 2. The fixture used in the production of this inertial sensor, through the use of pads, can utilize its own elasticity to avoid damaging the sensor. At the same time, the mounting cover and sound-absorbing cotton can reduce the noise generated by the drive motor during operation, preventing excessive noise from affecting the staff.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figures 1 to 4This embodiment describes a fixture for producing an inertial sensor, including a fixed platform 1. An adjustment and fixing assembly for adjusting the orientation angle and quick fixing is provided inside the fixed platform 1. The adjustment and fixing assembly includes a rotating column 2 rotatably connected to the inner bottom wall of the fixed platform 1. A worktable 3 is fixedly connected to the top of the rotating column 2. A drive motor 4 is fixedly connected to the right side of the fixed platform 1. A bevel gear 5 is fixedly connected to the output shaft of the drive motor 4. A bevel gear ring 6 is fixedly connected to the outer side of the worktable 3. A fixing frame 7 is fixedly connected to the top of the worktable 3. Cylinders 8 are fixedly connected to the left and right sides of the fixing frame 7. A fixing plate 9 is fixedly connected to the output shaft of the cylinders 8. Two movable rods 10 are fixedly connected to the inner side of the fixing frame 7. The fixing plates 9 are slidably connected to the movable rods 10. The two cylinders 8 can simultaneously drive the two fixing plates 9 to slide on the outer surface of the movable rods 10, thereby approaching the sensor and quickly clamping its left and right sides. The clamping efficiency is high, and the sensor is positioned in the middle of the fixing frame 7.
[0026] The drive motor 4 can drive the worktable 3 to rotate in the opposite direction to the output shaft of the drive motor 4 through the meshing transmission between the bevel gear 5 and the bevel gear ring 6, thereby adjusting the orientation angle of the sensor in real time for easy installation.
[0027] It should be noted that this application can ensure that the piston rods of two cylinders 8 extend and retract simultaneously by using a synchronization controller or synchronization valve, thereby achieving synchronous operation. These synchronization devices are common and mature in the field of pneumatic control, so they will not be described in detail in the specific embodiments.
[0028] In this embodiment, a pad 11 is bonded to the inner side of the fixing plate 9. The pad 11 is made of silicone and can utilize its own elasticity to avoid damaging the sensor.
[0029] In this embodiment, a mounting cover 12 is fixedly installed on the outside of the drive motor 4, and a sound-absorbing cotton 13 for reducing noise is glued to the inside of the mounting cover 12. The mounting cover 12 and the sound-absorbing cotton 13 can reduce the noise generated by the drive motor 4 during operation and prevent excessive noise from affecting the staff.
[0030] It should be noted that the mounting cover 12 has heat dissipation vents on both the front and back. A dustproof net is fixedly connected to the inside of the heat dissipation vents. The heat dissipation vents and the dustproof net can achieve the functions of natural heat dissipation and dust prevention for the drive motor 4.
[0031] Specifically, the bevel gear 5 meshes with the bevel gear ring 6 for transmission, and both the fixed table 1 and the worktable 3 are circular in shape.
[0032] It should be noted that a movable plate 14 is fixedly connected to the bottom of the fixed platform 1, and casters 15 are rotatably connected around the bottom of the movable plate 14. The movable plate 14 and the casters 15 facilitate the movement of the fixed platform 1.
[0033] In this embodiment, a frame 16 is fixedly connected to both the front and back of the fixed platform 1. An electric push rod 17 is fixedly connected to the top of the frame 16. A stop block 18 is fixedly connected to the output shaft of the electric push rod 17. The stop block 18 is an iron block. The electric push rod 17 can drive the stop block 18 to move vertically downwards, thereby stopping it against the ground to limit the position of the fixed platform 1 and prevent it from moving randomly.
[0034] The working principle of the above embodiments is as follows:
[0035] During use, the operator simultaneously activates two cylinders 8, which simultaneously drives two fixed plates 9 to slide on the outer surface of the movable rod 10, thereby approaching the sensor and quickly clamping it on both sides, placing the sensor in the middle of the fixed frame 7. During this process, the drive motor 4 is activated, which, through the meshing transmission between the bevel gear 5 and the bevel gear ring 6, drives the worktable 3 to rotate in the opposite direction to the output shaft of the drive motor 4, thereby adjusting the orientation angle of the sensor in real time for easy installation. In addition, the pad 11 can utilize its own elasticity to prevent the sensor from being pinched or damaged. At the same time, the mounting cover 12 and the sound-absorbing cotton 13 can reduce the noise generated by the drive motor 4 during operation, preventing excessive noise from affecting the operator.
[0036] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
