Description

Technical Field

[0001] This utility model relates to the field of ring proximity sensor technology, and in particular to a high-sensitivity ring proximity sensor. Background Technology

[0002] A ring proximity sensor is a non-contact detection device based on electromagnetic induction. It detects targets through the eddy current effect between an alternating magnetic field and a metal object. During operation, an alternating magnetic field is generated at the sensor's circular opening. When a metal object approaches the sensor, the alternating magnetic field induces eddy currents in the metal object, causing a change in the oscillation within the oscillator. This change in oscillation is detected and processed by the sensor's internal circuitry, which then outputs a switching signal to determine the proximity of the metal object. It is commonly used for screw counting or confirming the positioning of metal workpieces in automated equipment. Commonly used proximity sensors include the miniature cylindrical proximity switch CM / CS series. The following are listed: P-1, CC-D series two-wire cylindrical proximity switch P-16, CW-G series high-voltage cylindrical proximity switch P-23, CL1 series flat proximity switch P-31, CC series cylindrical proximity switch P-6, CC-Q series plug-in cylindrical proximity switch P-18, CW-N series high-temperature cylindrical proximity switch P-24, CT1 series square proximity switch P-32, CC-S series ultra-short cylindrical proximity switch P-14, CW-TE series corrosion-resistant cylindrical proximity switch P-20, CW-AM series all-metal cylindrical proximity switch TP-26, and CZ series Hall magnetic proximity switch P-36.

[0003] As disclosed in announcement number CN213633873U, a ring-shaped proximity sensor includes a base, a vertically fixed pole connected to the base surface of the base, a movably mounted clamping mechanism on the pole, and a receiving mechanism fixedly connected to the side wall near the top. The clamping mechanism includes a lifting square tube, a locking bolt threaded to the side wall of the lifting square tube, and an L-shaped plate fixedly connected to the side wall. A guide strip is fixedly connected to the inner side of the L-shaped plate, and a clamping plate slidably passes through the outer wall of the guide strip. A drive screw is threaded through the clamping plate. The ring-shaped proximity sensor is clamped between the L-shaped plate and the clamping plate. This utility model relates to the field of sensor technology. This utility model solves the problems of inconvenient installation of ring-shaped proximity sensors in actual use, requiring the use of bolts and screwdrivers for installation and disassembly, and the small sensing hole of the ring-shaped proximity sensor, which often results in misalignment during material receiving.

[0004] While common ring proximity sensors are easy to install or remove, they lack protective devices during operation and are often partially damaged by collisions with the sensed object, thus affecting their normal use and reducing their lifespan. Utility Model Content

[0022] The present invention will be further described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] like Figures 1-5As shown, this embodiment provides a high-sensitivity ring proximity sensor, including a ring proximity sensor body 1. A ring support plate 2 is fixedly installed on one side of the upper end of the ring proximity sensor body 1. A ring mounting plate 4 is installed on the upper end of the ring support plate 2 through a mounting assembly 3 that is easy to disassemble and replace. A ring groove 5 is opened on the upper end of the ring mounting plate 4. A feed hopper 6 is inserted into the ring groove 5. A protective assembly 7 is installed in the ring groove 5. One end of the protective assembly 7 is connected to the feed hopper 6. A buffer pad 8 is fixedly installed on the inner side of the feed hopper 6. In use, the ring proximity sensor body 1 is an existing structure, and a conventional one can be selected. First, the ring proximity sensor... The sensor body 1 is fixedly installed in the corresponding position for detection. Metal objects enter the inner side of the annular support plate 2 and the annular mounting plate 4 through the feed hopper 6, and then pass through the circular hole of the annular proximity sensor body 1. The annular proximity sensor body 1 confirms that the metal workpiece is in place. The buffer pad 8 inside the feed hopper 6 first provides initial buffering for the metal object, and the protective component 7 further buffers the metal object to prevent the annular proximity sensor body 1 from being partially damaged by the collision of the metal object, thereby improving its service life. When it is necessary to disassemble or replace the annular mounting plate 4, it can be replaced manually through the mounting component 3, which is convenient, quick, time-saving and labor-saving.

[0024] like Figure 2 and Figure 3 As shown, the mounting assembly 3 includes an arc-shaped plate 301, a first telescopic rod 302, and a first spring 303. The outer side of the annular support plate 2 has symmetrically arranged circular grooves. One end of the first telescopic rod 302 is fixedly installed in the circular groove, and the free end of the first telescopic rod 302 is fixedly connected to the arc-shaped plate 301. The first spring 303 is sleeved on the outer side of the first telescopic rod 302, with one end fixedly installed in the circular groove and the other end fixedly connected to the arc-shaped plate 301. The upper end of the annular support plate 2 has guide grooves 304 arranged in a circular array. A guide rod 306 with a square hole 305 on its outer side is inserted into the guide groove 304. One end of the guide rod 306 is fixedly connected to the annular mounting plate 4. Two springs are fixedly installed on both sides of one end of the arc-shaped plate 301. The square rod 307 extends into the square hole 305 at one end. When it is necessary to disassemble or replace the annular mounting plate 4, first manually move the arc plate 301 to one side, which will move the square rods 307 on both sides so that one end of them is disengaged from the square hole 305, thus releasing the fixing effect on the guide rod 306. At this time, the first telescopic rod 302 extends and the first spring 303 is stretched. Then, move the annular mounting plate 4 upward to separate it from the annular support plate 2. Then, release the arc plate 301. Under the action of the deformation force of the first spring 303, the arc plate 301 automatically resets. The friction force generated inside the first telescopic rod 302 can counteract the elastic potential energy of the first spring 303, preventing the arc plate 301 from moving repeatedly.

[0025] like Figure 5As shown, the protective component 7 includes a damping telescopic rod 701 and a buffer spring 702. The damping telescopic rod 701 is circumferentially distributed and installed in the annular groove 5. The free end of the damping telescopic rod 701 is fixedly connected to the feed hopper 6. The buffer spring 702 is sleeved on the outside of the damping telescopic rod 701. One end of the buffer spring 702 is fixedly installed in the annular groove 5, and the other end is fixedly connected to the feed hopper 6. During use, when a metal object enters the circular hole of the annular proximity sensor body 1 through the feed hopper 6, the damping telescopic rod 701 and the buffer spring 702 buffer the metal object, preventing the metal object from directly impacting the annular proximity sensor body 1. This protects the annular proximity sensor body 1 from damage caused by the collision with the metal object, thereby improving its service life. Figure 6 This is a schematic diagram of a commonly used proximity sensor model according to this utility model.
