Description

Technical Field

[0001] The utility model relates to the technical field of displacement sensor installation, in particular to a magnetostrictive displacement sensor installation mechanism. Background Technique

[0002] The magnetostrictive displacement sensor accurately measures the actual displacement value of the detected product by precisely detecting the absolute position of the moving magnetic ring through the internal non-contact measurement and control technology; the high precision and high reliability of this sensor have been widely applied in thousands of actual cases. Since there is no direct contact between the moving magnetic ring and the sensitive element for determining the position, the sensor can be applied in extremely harsh industrial environments and is not easily affected by oil stains, solutions, dust or other contaminants. In addition, the sensor adopts high-tech materials and advanced electronic processing technology, so it can be applied in environments with high temperature, high pressure and high vibration. The output signal of the sensor is the absolute displacement value. Even if the power supply is interrupted and reconnected, the data will not be lost, and there is no need to re-zero. Since the sensitive element is non-contact, even if the detection is repeated continuously, it will not cause any wear to the sensor, which can greatly improve the detection reliability and service life.

[0003] The traditional installation mechanism directly fixes and installs the magnetostrictive displacement sensor with other devices and cannot be adjusted. When the magnetostrictive displacement sensor is not in the same direction as the moving direction of the measured object, it will cause deformation of the magnetostrictive displacement sensor. At the same time, after the magnetostrictive displacement sensor is fixedly installed, maintenance and replacement are very troublesome. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a magnetostrictive displacement sensor installation mechanism, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a magnetostrictive displacement sensor installation mechanism, including an installation shell, a sensor body is installed in the middle of the installation shell through a fixing mechanism, an adjusting mechanism is arranged below the installation shell, and a fixing plate is arranged below the adjusting mechanism;

[0006] The fixing mechanism includes a clamping plate, a limiting sleeve, an inner knob I and a limiting rod. One side of the limiting sleeve is fixedly connected to the middle of the left and right sides of the installation shell. The outer circumference of the limiting rod penetrates through the left and right sides of the installation shell and is slidably connected to the middle of the limiting sleeve. One side of the limiting rod is threadedly connected to the side of the limiting sleeve away from the installation shell. The middle of the inner knob I is threadedly connected to the outside of the limiting rod. The middle of the clamping plate is fixedly connected to the end of the limiting rod away from the inner knob I.

[0007] Preferably, a plurality of installation holes are arranged at the front and rear ends of the fixing plate.

[0008] Preferably, a limiting block is provided at one end of the limiting rod away from the clamping plate.

[0009] Preferably, a protective pad is provided at one end of the clamping plate away from the limiting rod.

[0010] Preferably, the adjusting mechanism includes a lower connecting seat, a worm gear, a worm, a second knob, an upper connecting seat and a housing. The upper end of the upper connecting seat is fixedly connected to the middle of the lower side of the mounting shell. The upper part of the lower connecting seat is rotatably connected to the outer side of the lower part of the upper connecting seat. The lower end of the lower connecting seat is fixedly connected to the middle of the upper side of the fixing plate. The middle of the worm gear is fixedly connected to the lower side of the upper connecting seat. The housing is sleeved on the outer periphery of the worm gear and connected to the lower connecting seat. The worm is rotatably connected to the lower part of the housing. The outer periphery of the worm gear meshes with the outer periphery of the worm. One end of the worm penetrates through the housing and is fixedly connected with a second knob.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. First, place the sensor body inside the mounting shell and make the edge of the sensor body fit with the bottom edge of the mounting shell, so that the sensor body is parallel to the mounting shell. Then rotate the inner first knob. Since the limiting sleeve restricts the rotation of the limiting rod, the left-right rotating inner first knob can drive the limiting rod to move left and right, so that the clamping plate clamps on the left and right sides of the sensor body, thereby fixing the sensor body inside the mounting shell. It is convenient to disassemble and install the sensor body, and convenient for its maintenance and replacement.

[0014] 2. After the device is installed, start the laser pen to emit laser. Then measure the distance between the laser and the measured object with a ruler at each certain distance, so as to judge whether the sensor body is horizontal with the traveling direction of the measured object, thereby protecting the sensor body from being bent by force during use. When the sensor body is not horizontal with the traveling direction of the measured object, rotate the second knob, so that the worm drives the worm gear to rotate, so that the upper connecting seat drives the mounting shell to rotate, thereby adjusting the sensor body.

Specific embodiments

[0020] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] As Figures 1-4 shown, a magnetostrictive displacement sensor installation mechanism includes an installation shell 1. The sensor body 3 is installed in the middle of the installation shell 1 through a fixing mechanism 2. An adjustment mechanism 4 is arranged below the installation shell 1, and a fixing plate 5 is arranged below the adjustment mechanism 4.

[0022] In this embodiment, the fixing mechanism 2 includes a clamping plate 201, a limiting sleeve 202, an inner knob 1 203 and a limiting rod 204. One side of the limiting sleeve 202 is fixedly connected to the middle of the left and right sides of the installation shell 1. The outer circumference of the limiting rod 204 penetrates through the left and right sides of the installation shell 1 and is slidably connected to the middle of the limiting sleeve 202. One side of the limiting rod 204 is threadedly connected to the side of the limiting sleeve 202 away from the installation shell 1. The middle of the inner knob 1 203 is threadedly connected to the outside of the limiting rod 204. The middle of the clamping plate 201 is fixedly connected to the end of the limiting rod 204 away from the inner knob 1 203. A plurality of installation holes are arranged at the front and rear ends of the fixing plate 5. A limiting block 205 is arranged at the end of the limiting rod 204 away from the clamping plate 201. A protection pad 206 is arranged at the end of the clamping plate 201 away from the limiting rod 204.

[0023] Specifically, first, place the sensor body 3 inside the installation shell 1, and make the edge of the sensor body 3 fit with the bottom edge of the installation shell 1, so that the sensor body 3 is parallel to the installation shell 1. Then rotate the inner knob 1 203. Since the limiting sleeve 202 restricts the rotation of the limiting rod 204, the left and right rotating inner knob 1 203 can drive the limiting rod 204 to move left and right, so that the clamping plate 201 clamps on the left and right sides of the sensor body 3, thereby fixing the sensor body 3 inside the installation shell 1. It is convenient to disassemble and install the sensor body 3 and convenient for its maintenance and replacement.

[0024] In this embodiment, the adjusting mechanism 4 includes a lower connecting seat 402, a worm gear 403, a worm 404, a second knob 405, an upper connecting seat 406 and a housing. The upper end of the upper connecting seat 406 is fixedly connected to the middle of the lower side of the mounting shell 1. The upper part of the lower connecting seat 402 is rotatably connected to the outer side of the lower part of the upper connecting seat 406. The lower end of the lower connecting seat 402 is fixedly connected to the middle of the upper side of the fixing plate 5. The middle of the worm gear 403 is fixedly connected to the lower side of the upper connecting seat 406. The housing is sleeved on the outer periphery of the worm gear 403 and connected to the lower connecting seat 402. The worm 404 is rotatably connected to the lower part of the housing. The outer periphery of the worm gear 403 is meshed with the outer periphery of the worm 404. One end of the worm 404 penetrates through the housing and is fixedly connected with a second knob 405. A plurality of laser pointers 401 are arranged at equal intervals on the right side of the mounting shell 1, and the number of laser pointers 401 is at least three.

[0025] Specifically, after the device is installed, start the laser pointer 401 to emit laser light. Then, measure the distance between the laser and the object to be measured with a ruler at each certain distance, so as to judge whether the sensor body 3 is horizontal with the traveling direction of the object to be measured, thereby protecting the sensor body 3 from being bent by force during use. When the sensor body 3 is not horizontal with the traveling direction of the object to be measured, rotate the second knob 405, so that the worm 404 drives the worm gear 403 to rotate, thereby enabling the upper connecting seat 406 to drive the mounting shell 1 to rotate, so as to adjust the sensor body 3.

[0026] Working principle:

[0027] First, place the sensor body 3 inside the mounting shell 1 and make the edge of the sensor body 3 fit with the bottom edge of the mounting shell 1, so that the sensor body 3 is parallel to the mounting shell 1. Then rotate the inner first knob 203. Since the limit sleeve 202 restricts the rotation of the limit rod 204, the left-right rotation of the inner first knob 203 can drive the limit rod 204 to move left and right, so that the clamping plate 201 clamps on both sides of the sensor body 3, thereby fixing the sensor body 3 inside the mounting shell 1. It is convenient to disassemble and install the sensor body 3 and convenient for its maintenance and replacement. After the device is installed, start the laser pointer 401 to emit laser light. Then, measure the distance between the laser and the object to be measured with a ruler at each certain distance, so as to judge whether the sensor body 3 is horizontal with the traveling direction of the object to be measured, thereby protecting the sensor body 3 from being bent by force during use. When the sensor body 3 is not horizontal with the traveling direction of the object to be measured, rotate the second knob 405, so that the worm 404 drives the worm gear 403 to rotate, thereby enabling the upper connecting seat 406 to drive the mounting shell 1 to rotate, so as to adjust the sensor body 3.
