Description

Technical Field

[0001] This utility model relates to the field of three-component sensor technology, specifically a magnetic gradient measurement device based on a three-component sensor. Background Technology

[0002] A three-component sensor is a precision device that can simultaneously measure forces in three directions in space. It is widely used in industrial, medical equipment, and sports technology fields. It features high precision, high stability, and high reliability. It can not only measure forces in three directions, but also perform force measurements of various properties, such as tension, pressure, and torque. There are many different magnetic gradient measurement devices based on three-component sensors on the market.

[0003] However, conventional magnetic gradient measurement devices based on three-component sensors are not convenient for adjusting the position of the three-component sensors for magnetic gradient measurement. As a result, when measuring positions at different angles, the three-component sensors may not be able to measure the gradient accurately. It is also not convenient to adjust the position of the three-component sensors according to the height of the space to be measured, so when the three-component sensors need to detect at different heights, they may not be able to detect the gradient accurately. Furthermore, it is not convenient to clamp three-component sensors of different sizes, so when using different three-component sensors to measure the gradient of objects of different sizes, the measurement data may be inaccurate. Therefore, we propose a magnetic gradient measurement device based on three-component sensors to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a magnetic gradient measurement device based on a three-component sensor, to solve the problems mentioned in the background art. These problems include: the inconvenience of adjusting the position of the three-component sensor for magnetic gradient measurement, leading to inaccurate measurements when measuring different angles; the difficulty of adjusting the position of the three-component sensor according to the required height of the space to be measured, resulting in inaccurate detection when the three-component sensor needs to detect at different heights; and the difficulty of clamping three-component sensors of different sizes, leading to inaccurate measurement data when using different three-component sensors to measure the gradient of objects of different sizes.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a magnetic gradient measurement device based on a three-component sensor, comprising a support base for support;

[0006] Also includes:

[0007] The main gear has a connecting gear meshing at its upper end, and a limit plate is fixedly connected to the left end of the connecting gear, and a slide rod is fixedly connected to the right end of the limit plate.

[0008] The first slide plate has a telescopic structure on its outer side, wherein the telescopic structure includes a second slide plate, a belt body and a first pulley, a hydraulic rod is fixedly connected to the upper rear end of the first slide plate, the second slide plate is connected to the inner right end of the first slide plate via a slot, and the belt body is fixedly connected to the front end of the first slide plate.

[0009] The driving gear has a rack plate meshing with both its upper and lower ends, and the outer right end of the rack plate rotates to connect to the inside of the fixed plate, while the outer left end of the fixed plate is slidably connected to a clamping plate.

[0010] Preferably, a first motor is fixedly connected to the right end of the main gear, and a support base is fixedly connected to the lower end of the first motor.

[0011] Preferably, the outer right end of the slide rod is slidably connected to the inner left end of the support base.

[0012] Preferably, a limiting plate is fixedly connected to the right end of the hydraulic rod, and the lower inner side of the belt body is tightly fitted with the first pulley, and the upper inner side of the first pulley is tightly fitted with the second pulley.

[0013] Preferably, the outer right ends of the first and second pulleys are rotatably connected to the inside of the limiting plate, and the outer right end of the second slide plate is connected to the limiting plate via a slot, and the outer front end of the belt body is connected to the limiting plate via a slot.

[0014] Preferably, a rack plate is fixedly connected to the right end of the clamping plate, and the clamping plates are symmetrically arranged on the outer sides of the front and rear ends of the fixed plate. A second motor is fixedly connected to the right end of the drive gear, and a first sliding plate is fixedly connected to the right end of the fixed plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the magnetic gradient measurement device based on a three-component sensor can perform magnetic gradient measurement for different angles of the object being measured, can extend the detection height of the three-component sensor, and can perform magnetic gradient detection on objects of different heights, thus avoiding the situation where the three-component sensor shakes during the measurement process, resulting in inaccurate magnetic gradient data.

[0016] 1. It is equipped with a main gear, a connecting gear, and a limiting plate. The rotation of the main gear drives the connecting gear meshing with the outer side of the upper end of the main gear to rotate, and drives the limiting plate fixedly connected to the left end of the connecting gear to rotate. This configuration can rotate the three-component sensor upward or downward to avoid the three-component sensor needing to measure different positions.

[0017] 2. It is equipped with a support base, a sliding rod and a limiting plate. By rotating the limiting plate, the sliding rod, which is symmetrically arranged in an arc shape on the outer side of the right end of the limiting plate, will rotate at the same time. At this time, the outer side of the right end of the sliding rod slides on the upper left side of the support base, which can prevent instability during rotation.

[0018] 3. It is equipped with a hydraulic rod, a first sliding plate and a second sliding plate. By activating the hydraulic rod, the first sliding plate, which is fixedly connected to the lower end of the hydraulic rod, moves downward. At this time, the outer right end of the first sliding plate is slidably connected to the outer left end of the second sliding plate, which limits the first sliding plate and can move the first sliding plate downward, extending the measurement position and avoiding situations where the position to be measured is too high or too low.

[0019] 4. It is equipped with a belt body, a first pulley and a second pulley. The movement of the first slide plate drives the belt body fixedly connected to the front end of the first slide plate to move downward, and drives the belt body to rotate on the outside of the first pulley and the second pulley. This causes the right outer side of the first pulley and the second pulley to rotate inside the second slide plate, which can extend the two sections to the same length and restrain each other, limiting each other and preventing the extended part from being too weak and breaking.

[0020] 5. It is equipped with a drive gear, rack plates, and clamping plates. The rotation of the drive gear drives the rack plates connected to the upper and lower ends of the drive gear to move in opposite directions at the same time. It also drives the clamping plates fixed to the left ends of the two rack plates to move in opposite directions. This can clamp the three-component sensor and avoid shaking during the measurement process, which would cause inaccurate measurement data. Attached Figure Description

[0027] 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.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a magnetic gradient measurement device based on a three-component sensor, comprising a support base 1, a first motor 2, a main gear 3, a connecting gear 4, a slide rod 5, a limiting plate 6, a hydraulic rod 7, a first sliding plate 8, a second sliding plate 9, a belt body 10, a first pulley 11, a second pulley 12, a fixing plate 13, a second motor 14, a drive gear 15, a rack plate 16, and a clamping plate 17.

[0029] Example 1: Please refer to Figure 1 and Figure 2 Existing magnetic gradient measurement devices based on three-component sensors are not convenient for adjusting the position of the three-component sensor for magnetic gradient measurement. As a result, when it is necessary to measure positions at different angles, the three-component sensor may not be able to measure accurately. In order to solve this technical problem, this embodiment discloses the following technical content.

[0030] A magnetic gradient measurement device based on a three-component sensor includes a support base 1. A first motor 2 is fixedly connected to the upper right side of the support base 1, and a main gear 3 is fixedly connected to the left side of the first motor 2. A connecting gear 4 is meshed with the upper outer side of the main gear 3. A limiting plate 6 is fixedly connected to the left side of the connecting gear 4, and a sliding rod 5 is fixedly connected to the upper and lower sides of the right side of the limiting plate 6, and the right end of the sliding rod 5 is slidably connected to the upper left side of the support base 1.

[0031] When it is necessary to adjust the measurement angle of the three-component sensor, the first motor 2 is started, which drives the main gear 3 fixedly connected to the left end of the first motor 2 to rotate, and drives the connecting gear 4 meshing with the upper end of the main gear 3. When the connecting gear 4 rotates, it drives the limiting plate 6 fixedly connected to the left end of the connecting gear 4 to rotate. At this time, the two sliding rods 5 fixedly connected to the right side of the limiting plate 6 slide on the upper left side of the support base 1 to limit the limiting plate 6, which can perform magnetic gradient measurement for different angles of the measured object.

[0032] Example 2: Please refer to Figure 1 and Figure 3 Existing magnetic gradient measurement devices based on three-component sensors are not convenient for adjusting the position of the three-component sensors according to the height of the space to be measured. As a result, when the three-component sensors need to detect at different heights, the detection may be incomplete. In order to solve this technical problem, this embodiment discloses the following technical content.

[0033] A magnetic gradient measurement device based on a three-component sensor includes a limiting plate 6. A hydraulic rod 7 is fixedly connected to the rear left end of the limiting plate 6, and a first sliding plate 8 is fixedly connected to the lower end of the hydraulic rod 7. A second sliding plate 9 is connected to the outer side of the limiting plate 6 via a slot. The second sliding plate 9 is also connected to the inner right end of the first sliding plate 8 via a slot. A second pulley 12 is rotatably connected to the inner left end of the second sliding plate 9. The outer side of the second pulley 12 is tightly fitted to a belt body 10. The inner lower end of the belt body 10 is tightly fitted to a first pulley 11. The outer right end of the first pulley 11 is rotatably connected to the inner lower end of the second sliding plate 9. The rear end of the belt body 10 is fixedly connected to the first sliding plate 8.

[0034] When it is necessary to extend the three-component sensor to detect higher positions, the hydraulic rod 7 is activated, causing the lower end of the hydraulic rod 7 to be fixedly connected to the first slide plate 8 to move downward. At this time, the inner right side of the first slide plate 8 slides downward on the outer left side of the second slide plate 9, and drives the belt body 10 fixedly connected to the inner front section of the first slide plate 8 to rotate. At this time, the belt body 10 rotates on the outer side of the first pulley 11 and the second pulley 12, causing the outer front end of the belt body 10 to slide on the inner left side of the limiting plate 6, driving the second slide plate 9 to move downward on the outer left side of the limiting plate 6. This can extend the detection height of the three-component sensor and perform magnetic gradient detection on objects of different heights.

[0035] Example 3: Please refer to Figure 1 , Figure 4 and Figure 5Existing magnetic gradient measurement devices based on three-component sensors are not convenient for clamping three-component sensors of different sizes. As a result, when it is necessary to use different three-component sensors to measure the gradient of objects of different sizes, inaccurate measurement data may easily occur. In order to solve this technical problem, this embodiment discloses the following technical content.

[0036] A magnetic gradient measurement device based on a three-component sensor includes a fixed plate 13. The right end of the fixed plate 13 is fixedly connected to a first sliding plate 8, and the outer side of the right end of the fixed plate 13 is fixedly connected to a second motor 14. The left end of the second motor 14 is fixedly connected to a drive gear 15. The outer sides of both the upper and lower ends of the drive gear 15 are meshed with rack plates 16. The left end of the rack plate 16 is fixedly connected to a clamping plate 17, and the outer side of the right end of the clamping plate 17 is slotted to the fixed plate 13.

[0037] When it is necessary to limit the three-component sensor, the second motor 14 is started, which drives the drive gear 15 fixedly connected to the left end of the second motor 14 to rotate. This causes the rack plates 16, which are meshed on the outer sides of the upper and lower ends of the drive gear 15, to move in opposite directions at the same time. At this time, the rack plates 16 drive the clamping plate 17 fixedly connected to the left end to move. At the same time, the outer side of the right end of the clamping plate 17 slides on the left end of the fixed plate 13 to limit the clamping plate 17. The three-component sensor is placed inside the two clamping plates 17, and the drive gear 15 is controlled to rotate in opposite directions. This causes the rack plates 16, which are meshed on the outer sides of the upper and lower ends of the drive gear 15, to move inward. This causes the clamping plate 17 fixedly connected to the left end of the rack plate 16 to move inward and clamp the three-component sensor. This can prevent the three-component sensor from shaking during the measurement process, which would lead to inaccurate magnetic gradient data.
