Mounting mechanism for a hall sensor

Abstract

This utility model relates to the field of installation mechanism technology, and proposes an installation mechanism for a Hall sensor, including a base plate for mounting on an external device. A horizontal adjustment component is fixedly connected to the base plate, and the horizontal adjustment component includes a mounting base. A vertical adjustment component for fixing the Hall sensor is provided on the horizontal slide. This utility model employs a symmetrically arranged L-shaped ratchet structure that engages with a spring-driven pawl. A pull rope linked to the pawl is provided at the lower end of the fastening knob. When the fastening knob is tightened, the rubber column presses against the mounting base to achieve primary locking. Simultaneously, the pull rope loosens, and the pawl automatically resets under the action of the spring and engages with the ratchet, forming a bidirectional mechanical self-locking mechanism. This technical solution solves the problem in existing technologies where the risk of bidirectional displacement under equipment vibration or external force interference is not addressed, ultimately leading to a deviation of the relative position of the Hall sensor and the detection target from the preset value, affecting detection accuracy.

Description

Technical Field

[0001] This utility model relates to the field of installation mechanism technology, specifically to an installation mechanism for a Hall sensor. Background Technology

[0002] A Hall sensor is a sensor based on the Hall effect. A Hall sensor is a sensor that generates an output voltage pulse when an alternating magnetic field passes through it. In the monitoring of the operating status of equipment such as motors and machine tools, Hall sensors are widely used to accurately detect key parameters such as speed and position. Their detection accuracy is highly dependent on the sensor's installation position relative to the magnet being measured, typically requiring fine horizontal and vertical adjustments and long-term stability after calibration.

[0003] In the existing technology, after the Hall sensor is installed and tightened, it cannot cope with the risk of bidirectional displacement under equipment vibration or external force interference, which eventually causes the relative position of the Hall sensor and the detection target to deviate from the preset value, affecting the detection accuracy and the measurement results to be inaccurate. Utility Model Content

[0004] This invention proposes a mounting mechanism for a Hall sensor, which solves the problem in related technologies that cannot cope with the risk of bidirectional displacement under equipment vibration or external force interference, ultimately causing the relative position of the Hall sensor and the detection target to deviate from the preset value, thus affecting the detection accuracy.

[0005] The technical solution of this utility model is as follows: A mounting mechanism for a Hall sensor includes a base plate for mounting on an external device. A horizontal adjustment component is fixedly connected to the base plate. The horizontal adjustment component includes a mounting base fixedly connected to the base plate. A guide hole is provided on the mounting base. A limit plate is fixedly connected to the rear end of the mounting base. A horizontal slide is slidably mounted in the guide hole. Side plates are fixedly connected to both sides of the horizontal slide. Several ratchet bars are fixedly connected to the side of each side plate near the mounting base. Mounting brackets are fixedly connected to both sides of the horizontal slide. Pads are hinged to the mounting brackets. A spring is provided between the pads and the mounting brackets. A threaded hole is provided on the horizontal slide. A fastening knob is screwed into the threaded hole. A rubber post is fixedly connected to the lower end of the fastening knob. A vertical adjustment component for fixing the Hall sensor is provided on the horizontal slide.

[0006] Preferably, the ratchet has an L-shaped structure, and the short sides of the ratchet on the side plates on both sides of the mounting base face opposite directions.

[0007] Preferably, through holes are provided on both sides of the horizontal slide block, and a pull rope is fixedly connected to the pawl. One end of the pull rope passes through the through hole and is fixedly connected to the rubber post.

[0008] Preferably, the vertical adjustment assembly includes a threaded seat, which is fixedly connected to a horizontal slide. A rotating rod is threadedly connected to the threaded seat, and a lifting slide is hinged to the lower end of the rotating rod. The lifting slide is slidably mounted on the threaded seat, and a fixing seat for fixing a Hall sensor is fixedly connected to the front end of the lifting slide.

[0012] Preferably, the rubber column is made of an elastic material, and the upper end surface of the rubber column is provided with textures to increase friction.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention employs a symmetrically arranged L-shaped ratchet structure in conjunction with a spring-driven pawl. A pull rope linked to the pawl is located at the lower end of the fastening knob. When the fastening knob is loosened, the pull rope automatically pulls the pawl away from the ratchet, releasing the self-locking mechanism and allowing the horizontal slide to slide freely for position adjustment. When the fastening knob is tightened, the rubber column presses against the mounting base to achieve primary locking, while the pull rope relaxes, and the pawl automatically resets under the action of the spring and engages with the ratchet, forming a two-way mechanical self-locking mechanism. This ensures that the sensor does not move unexpectedly during the detection process, improving the stability and reliability of the measurement. Attached Figure Description

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0023] Example

[0024] like Figures 1-4 As shown, this embodiment proposes a mounting mechanism for a Hall sensor, including a base plate 1. The base plate 1 can be fixed to external equipment such as a motor or machine tool by fasteners such as bolts. A horizontal adjustment assembly 2 is fixedly connected to the base plate 1. The horizontal adjustment assembly 2 includes a mounting base 201, which is fixedly connected to the base plate 1. A guide hole 202 is provided on the mounting base 201. A limit plate 203 is fixedly connected to the rear end of the mounting base 201. A horizontal slide block 206 is slidably installed in the guide hole 202. Side plates 204 are fixedly connected to both sides of the horizontal slide block 206. Several ratchet bars 205 are fixedly connected to the side of each side plate 204 near the mounting base 201. Mounting brackets 208 are fixedly connected to both sides of the slide 206. Pads 209 are hinged to the mounting brackets 208. A spring 210 is provided between the pads 209 and the mounting brackets 208. A threaded hole is provided on the horizontal slide 206. A fastening knob 207 is screwed into the threaded hole. A rubber post 211 is fixedly connected to the lower end of the fastening knob 207. The rubber post 211 is made of elastic material. The upper end surface of the rubber post 211 is provided with texture to increase friction. A vertical adjustment component 3 for fixing the Hall sensor is provided on the horizontal slide 206. By rotating the rubber post 211 using the fastening knob 207, the horizontal slide 206 is fixed to the mounting base 201.

[0025] The ratchet 205 has an L-shaped structure, and the short sides of the ratchet 205 on the side plates 204 on both sides of the mounting base 201 face opposite directions. The engagement method between the pawl 209 and the ratchet 205 is similar to that of a ratchet wheel and pawl. By setting the ratchet 205 on both sides of the mounting base 201 to face opposite directions, this symmetrical ratchet structure design ensures that when the horizontal slide (206) tends to move in any direction, one side of the pawl (209) will engage with the vertical surface of the ratchet (205), forming an effective anti-backward mechanism. This can limit the forward and backward sliding of the horizontal slide 206 and prevent movement during the Hall sensor detection process, thereby affecting the detection results.

[0026] like Figure 4 As shown, through holes are provided on both sides of the horizontal slide 206. A pull rope 212 is fixedly connected to the pawl 209. One end of the pull rope 212 passes through the through hole and is fixedly connected to the rubber post 211. In order to avoid the engagement of the pawl 209 and the ratchet 205 affecting the adjustment of the position of the horizontal slide 206, when the fastening knob 207 is loosened, the rubber post 211 descends, the pull rope 212 is tightened and pulls the pawl 209 to rotate around the pin, overcoming the force of the spring 210 and disengaging it from the ratchet 205. At this time, the horizontal slide 206 can slide freely. When the adjustment is in place, the fastening knob 207 is tightened, the rubber post 211 rises and presses against the mounting base 201 to achieve locking. At the same time, the pull rope 212 is loosened, and the pawl 209 automatically resets under the action of the spring 210 and engages with the ratchet 205 to achieve self-locking.

[0027] like Figure 5 As shown, the vertical adjustment assembly 3 includes a threaded seat 301, which is fixedly connected to a horizontal slide 206. A rotating rod 302 is threadedly connected to the threaded seat 301, and a lifting slide 303 is hinged to the lower end of the rotating rod 302. The lifting slide 303 is slidably mounted on the threaded seat 301, and a fixing seat 306 for fixing a Hall sensor is fixedly connected to the front end of the lifting slide 303. A reference seat 304 is fixedly connected to the front end of the threaded seat 301, and an engraved... The scale rod 305 is slidably installed in the reference base 304. The lifting distance of the fixed base 306 can be precisely controlled by using the scale rod 305. During later maintenance, the movement distance of the scale rod 305 can be observed. The fixed base 306 can be raised or lowered to the initial installation position by rotating the rotating rod 302. The vertical adjustment assembly 3 also includes a cable management seat 307, which is fixedly connected to the front end of the lifting slide 303 to fix and organize the cable of the Hall sensor and prevent it from swinging randomly.

[0028] Working principle: First, the base plate 1 is fixed to the external device with bolts. When adjusting the horizontal position, loosen the fastening knob 207. The rubber column 211 at its lower end descends and tightens the pull rope 212. The pull rope 212 pulls the pawls 209 on both sides to overcome the elastic force of the spring 210 and rotate, disengaging them from the ratchet 205 on the side plate 204. At this time, the horizontal slide 206 can slide freely along the guide hole 202 of the mounting base 201. After adjusting to the target position, tighten the fastening knob 207. The rubber column 211 rises and presses against the bottom surface of the mounting base 201, achieving horizontal locking. At the same time, the pull rope 212 loosens, and the pawls 209 rotate. 09 is reset under the action of spring 210 and re-engages with ratchet 205 to form a two-way self-locking mechanism, preventing the horizontal slide 206 from moving accidentally. When adjusting the vertical position, rotating rod 302 drives the lifting slide 303 in the threaded seat 301 connected to it to slide up and down. The scale rod 305 fixed on the lifting slide 303 moves synchronously with it. The lifting distance can be precisely controlled by the scale on the reference seat 304. The Hall sensor is installed on the fixed seat 306, and its cable is fixed and organized by the cable management seat 307. During maintenance, the sensor can be reset to the initial installation height according to the indication of the scale rod 305.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
