Description

Technical Field

[0001] The utility model relates to the technical field of coil fixing, in particular to a sensor coil fixing device and a detection device. Background Technique

[0002] After the sensor coil is produced, the inductance of the sensor coil needs to be detected. When detecting the sensor coil, the sensor coil needs to be fixed first for convenient detection. Sensor coils come in different sizes. Currently, the fixing device for sensor coils cannot fix coils of different sizes, so the fixing of the sensor coil fixing device is relatively limited, and this problem needs to be solved.

[0003] The existing patent (publication number: CN208001214U) proposes a coil clamp and a motor coil fixing device. The coil clamp includes a clamp body and a clamp head. The clamp body and the clamp head are detachably connected, and a fixing groove for fixing the motor coil is provided on the clamp head. The coil clamp of this application solves the technical problem that the winding of the motor coil is prone to looseness after the winding of the motor coil is formed and before glue application or tape winding in the prior art.

[0004] The above-mentioned coil clamp and motor coil fixing device adopt a fixing groove provided in the clamping part to fix the coil by arranging the coil in the fixing groove. Since the size of the fixing groove is fixed, it is not possible to fix coils of different sizes. Therefore, we propose a sensor coil fixing device to solve the above problem. Content of the Utility Model

[0005] The utility model provides a sensor coil fixing device, which solves the technical problem that the current coil fixing device cannot fix coils of different sizes.

[0006] To solve the above technical problem, a sensor coil fixing device provided by the utility model includes an operation table. A bottom plate is arranged on the operation table. A fixing seat is fixed on the top of the bottom plate. A fixing disk is fixed on one side of the fixing seat. Fixing components are distributed at three points on the fixing disk in an equilateral triangle with the center of the fixing disk as the axis. Adjusting components are threadedly inserted into the fixing components. A bracket is fixed on the fixing disk. A fixing ring sleeve is fixed on the bracket. The adjusting components are rotatably inserted into the fixing ring sleeve.

[0007] Preferably, the fixing component includes fixing plates symmetrically distributed. The fixing plates are fixed on the fixing disk. A sliding groove is formed in the fixing plates. A fixing block is arranged between the symmetrically distributed fixing plates. Sliders are fixed on both sides of the fixing block. The sliders are clamped in the sliding groove. A push plate is fixed on one side of the fixing block. A push block is fixed at the end of the push plate away from the fixing block. A rubber plate is fixed on the side of the push block away from the push plate. An active block is fixed on the fixing block. The mediation component is threadedly inserted on the mediation component.

[0008] With the above technical solution: Since the fixing component includes fixing plates symmetrically distributed, the fixing plates are fixed on the fixing disk, a sliding groove is formed in the fixing plates, a fixing block is arranged between the symmetrically distributed fixing plates, sliders are fixed on both sides of the fixing block, the sliders are clamped in the sliding groove, a push plate is fixed on one side of the fixing block, a push block is fixed at the end of the push plate away from the fixing block, a rubber plate is fixed on the side of the push block away from the push plate, an active block is fixed on the fixing block, and the mediation component is threadedly inserted on the mediation component, by spirally rotating the adjustment component, the sliders on both sides of the fixing block can be controlled to move in the sliding groove, so that the push plate and the push block are pushed towards the center of the fixing disk, and the sensor coil is arranged at the center, thereby realizing the fixation of the sensor coil.

[0009] Preferably, the mediation component includes an adjustment knob. One end of the adjustment knob is fixed with an adjustment screw rod. The adjustment screw rod penetrates and is inserted into the fixed collar and extends to the active block. The adjustment screw rod is threadedly inserted into the active block. A fixing piece is fixed at one end of the adjustment screw rod close to the adjustment knob. A limiting block is fixed at the end of the adjustment screw rod away from the adjustment knob.

[0010] With the above technical solution: Since the mediation component includes an adjustment knob, one end of the adjustment knob is fixed with an adjustment screw rod, the adjustment screw rod penetrates and is inserted into the fixed collar and extends to the active block, the adjustment screw rod is threadedly inserted into the active block, a fixing piece is fixed at one end of the adjustment screw rod close to the adjustment knob, and a limiting block is fixed at the end of the adjustment screw rod away from the adjustment knob, by rotating the adjustment screw rod, since the adjustment screw rod is inserted into the fixed collar, the adjustment screw rod can be adjusted to rotate. Also, since one end of the fixed collar is the adjustment knob and the other end is the fixing piece, the adjustment screw rod will not move freely in the fixed collar, which enables the active block to only move on the adjustment screw rod, thereby ensuring the feasibility of the adjustment component.

[0011] Preferably, the bracket is L-shaped.

[0012] With the above technical solution: Since the bracket is L-shaped, one end of the bracket can be fixed on the fixing disk, the other end of the bracket can fix the fixed collar, and at the same time, the bracket folded into an L shape can extend the effective adjustment distance of the adjustment screw rod.

[0013] Preferably, the diameters of the fixing piece and the adjusting knob are both larger than the diameter of the fixing ring sleeve.

[0014] With the above technical solution: since the diameters of the fixing piece and the adjusting knob are both larger than the diameter of the fixing ring sleeve, the adjusting screw rod will not move within the fixing ring sleeve, thus ensuring the feasibility of the adjusting component to adjust the fixing component.

[0015] Preferably, the rubber plate is serrated.

[0016] With the above technical solution: since the rubber plate is serrated, the serrations can increase the friction between the rubber plate and the sensor coil. When fixing the sensor coil, the sensor coil will not move.

[0017] Preferably, a fixing seat is provided on the bottom plate, and the bottom plate is fixed on the operating table through the fixing seat.

[0018] With the above technical solution: since bolts are provided on the bottom plate and the bottom plate is fixed on the operating table through the bolts, the sensor coil fixing device can be disassembled and installed on the operating table.

[0019] This application also provides a detection device, and the detection device includes the above-mentioned sensor coil fixing device.

[0020] Compared with the related art, the utility model has the following beneficial effects:

[0021] 1. Compared with the traditional coil fixing device, the utility model is provided with an adjusting component. By turning the adjusting knob, the adjusting screw rod rotates to control the movement of the movable block in the fixing component, thereby controlling the distance between the pushing block and the center of the fixing disk, realizing the fixation of sensor coils of different sizes. At the same time, a fixing disk is provided, and fixing components are distributed at the three vertices of an equilateral triangle centered on the center of the fixing disk, so that the sensor coil is subjected to forces from three directions towards the center of the fixing disk during fixation, and the fixation is more stable.
