[0002] The high-precision three-axis magnetic field probe device is a device specially used to detect the size and direction of the magnetic field of an object in three-dimensional space.

[0003] The magnetic field probe in the existing magnetic field probe device is connected to a carrier plate, and the driving component in the magnetic field probe device drives the carrier plate to move in the X, Y and Z axes, thereby detecting the magnetic field changes of the object in these three axes. Since the objects to be detected have different shapes, the magnetic field probe in the magnetic field probe device can only detect the magnetic field at the upper end of the object, resulting in a limited detection range, which needs to be improved. Utility Model Content

[0004] The purpose of this application is to provide a high-precision three-axis magnetic field probe device in order to improve the detection range of the magnetic field probe.

[0005] A high-precision three-axis magnetic field probe device provided in the present application adopts the following technical solution: it includes a detection platform, the upper surface of the detection platform is slidably connected to a carrier plate, the detection platform is connected to a driving mechanism for driving the carrier plate to slide along the directions of the X-axis, Y-axis and Z-axis, the carrier plate is swingably connected to a placement plate, the carrier plate is connected to a swinging assembly for driving the placement plate to swing, and the placement plate is connected to a magnetic field probe.

[0006] By adopting the above technical solution, the driving mechanism drives the carrier plate to move in the directions of the X-axis, Y-axis and Z-axis, that is, the magnetic field probe moves with the movement of the carrier plate, so that the magnetic field probe can detect the magnetic field of the object in different directions. The swing assembly drives the placement plate to swing, that is, the magnetic field probe swings with the swing of the placement plate, so that the magnetic field probe is tilted compared to the placement plate, thereby increasing the detection range of the magnetic field probe.

[0007] Optionally, the carrier plate is rotatably connected to a connecting plate, the carrier plate is connected to a first driving member for driving the connecting plate to rotate, the placement plate is swingably connected to the connecting plate, the swing assembly is connected to the connecting plate, and the magnetic field probe is located at an eccentric position of the connecting plate.

[0008] By adopting the above technical solution, the first driving member drives the connecting plate to rotate, that is, the magnetic field probe rotates around the axis of the connecting plate, so that the magnetic field probe can detect the magnetic field on the outer surface of the object, thereby improving the detection range of the magnetic field probe.

[0009] Optionally, the swing assembly includes a worm rotatably connected to the connecting plate and a worm wheel connected to the placement plate, the worm wheel is engaged with the worm, and the connecting plate is connected to a second driving member for driving the worm to rotate.

[0011] Optionally, the magnetic field probe is connected to a mounting shell, the mounting shell is detachably connected to the placement plate, and the placement plate is connected to a fixing component for fixing the mounting shell.

The fixing plate restricts the movement of the mounting shell, thereby improving the stability of the mounting shell installed on the placement plate and preventing the mounting shell from detaching from the through hole.

[0015] Optionally, a baffle is connected to the inner wall of the through hole, and the baffle is provided with a receiving hole for the magnetic field probe to pass through, and when the mounting shell abuts against the baffle, the fixing column corresponds to the fixing hole.

[0016] By adopting the above technical solution, when the mounting shell abuts against the baffle, the fixing column corresponds to the fixing hole, which facilitates the fixing column to be inserted into the fixing hole, thereby improving the efficiency of fixing the mounting shell.

[0018] By adopting the above technical solution, when the fixed plate slides, the sliding cooperation between the limit block and the limit groove plays a guiding and limiting role in the sliding of the fixed plate, thereby improving the sliding stability of the fixed plate and preventing the fixed plate from falling out of the sliding groove during the sliding process.

The cover plate is then installed on the fixed plate through the locking piece to restrict the new fixed plate from leaving the slide groove.

[0021] Optionally, the inner wall of the limit groove is connected to an elastic positioning block, and the limit block is provided with two positioning grooves for cooperating with the elastic positioning block, and when the elastic positioning block is inserted into one of the positioning grooves, the clearance hole is aligned with the through hole; when the elastic positioning block is inserted into the other positioning groove, the clearance hole is staggered with the through hole.

[0022] By adopting the above technical solution, when the elastic positioning block is inserted into the positioning groove, the outer surface of the elastic positioning block fits with the inner wall of the positioning groove, and the elastic positioning block restricts the movement of the fixed plate, thereby improving the stability of the fixed plate placed in the slide groove.

[0023] Optionally, the fixing plate is connected to two active blocks, and when one of the active blocks is inserted into the slide groove, the other active block protrudes out of the slide groove.

[0024] By adopting the above technical solution, an active block protrudes from the slide groove, which makes it easy for the operator to observe whether the mounting shell is in a fixed or loose state.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:
