Description

A displacement measurement device based on a distance sensor Technical Field

[0001] This invention relates to the field of displacement measurement using distance sensors, and in particular to a displacement measurement device based on a distance sensor. Background Technology

[0002] A distance sensor is a type of sensor that uses the "time-of-flight" method to measure distance and detect the distance to an object. During the manufacturing process, distance sensors often require displacement testing.

[0003] A search revealed a displacement sensor disclosed in patent document CN210513073U, which facilitates measurement. The sensor includes a displacement sensor body with an L-shaped mounting plate at its lower part. A rectangular crossbar is fixedly connected to the inner wall of one side of the L-shaped mounting plate, and a rectangular tube is slidably fitted onto the crossbar. A rectangular vertical tube is fixedly connected to one end of the crossbar, and a rectangular vertical rod is slidably fitted inside the vertical tube. The top of the vertical rod extends above the vertical tube and is fixedly connected to the bottom of the displacement sensor body. A screw is rotatably installed inside the vertical tube, and the vertical rod is threaded onto the screw. This invention is reasonably designed, easy to use, and allows for easy adjustment of the height and horizontal position of the displacement sensor body according to actual needs. The adjustable horizontal position facilitates adjustment of the distance between the sensor and the object being measured, achieving convenient and accurate measurement, saving time and effort, improving adjustment efficiency, and meeting usage requirements.

[0004] The sensor body in the above devices is exposed, making it susceptible to dust accumulation and damage from impacts by foreign objects. This reduces the lifespan of the equipment and makes it less versatile. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a displacement measurement device based on a distance sensor, overcoming the deficiencies of existing technologies.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a displacement measuring device based on a distance sensor, comprising a base plate, a fixing plate disposed above the base plate, a support assembly for vertical movement of the fixing plate mounted on the upper end of the base plate, a protective shell mounted on the upper end of the fixing plate, a sensor body fixedly mounted inside the protective shell via a connecting rod, a through hole being formed on the inner wall of one side of the protective shell, the through hole being located at the sensing head position of the sensor body, two reciprocating lead screws being symmetrically rotatably connected to the inner wall of the protective shell, the two reciprocating lead screws being connected via a first pulley, a moving block being threadedly connected to the rod wall of each reciprocating lead screw, and the other ends of the two moving blocks being connected to a common... A cleaning frame is provided, through which the sensor body passes. A brush is installed on the inner side wall of the cleaning frame and is attached to the side wall of the sensor body. A drive assembly for rotating a reciprocating lead screw is installed on the protective shell. A heat dissipation assembly is installed inside the protective shell. A fan is installed on the outer side wall of one side of the protective shell, and an exhaust pipe is installed on the side wall of the fan. The other end of the exhaust pipe passes through the corresponding side wall of the protective shell and extends inward, where a suction head is installed. A cleaning assembly for cleaning dust is installed inside the suction head. A movable plate is slidably connected to the base plate, and a mounting bracket is connected to the upper end of the movable plate. A moving assembly for driving the movable plate to move horizontally is installed on the base plate.

[0007] By adopting the above technical solution, during use, the fixing plate is adjusted to the specified height using the support assembly, the object to be measured is placed on the mounting frame, and the sensor body is activated. The sensor body then measures the displacement of the object. Simultaneously, the protective shell protects the sensor body. When it is necessary to clean the dust on the surface of the sensor body, the reciprocating screws are rotated by the drive assembly. The two reciprocating screws rotate simultaneously through the first pulley. The rotation of the reciprocating screws causes two moving blocks to move back and forth horizontally through the thread action. The movement of the moving blocks drives the cleaning frame to move, which in turn drives the brush to move, cleaning the dust on the surface of the sensor body. At the same time, the fan is activated, and its operation uses the exhaust pipe to suck up dust. The exhaust pipe uses the suction head to absorb the dust stirred up inside the protective shell, preventing dust from falling back onto the sensor body. This structure protects the sensor body and also cleans the dust on its surface, thereby improving the service life of the equipment and enhancing the applicability of the device.

[0008] As a preferred embodiment of the present invention, the support assembly includes a cylinder fixedly mounted on the upper end of the base plate, and the piston end of the cylinder is connected to the fixed plate.

[0009] By adopting the above technical solution, the cylinder is activated, which in turn drives the fixed plate to move vertically.

[0010] As a preferred embodiment of the present invention, the drive assembly includes a motor fixedly mounted on the outer side wall of one side of the protective shell. The output end of the motor passes through the side wall of the protective shell and extends inward, and is connected to a corresponding reciprocating lead screw through a coupling.

[0011] By adopting the above technical solution, when the motor is started, the motor will drive the reciprocating lead screw to rotate.

[0012] As a preferred embodiment of the present invention, the heat dissipation assembly includes a rotating shaft rotatably connected to the inner wall of one side of the protective shell, one end of the rotating shaft is connected to a fan blade, and the fan blade is located on one side of the sensor body. The rotating shaft and the corresponding reciprocating lead screw are connected by a second pulley.

[0013] By adopting the above technical solution, the rotation of the reciprocating lead screw will drive the rotating shaft to rotate through the second pulley. The rotation of the rotating shaft will drive the fan blades to rotate, and the rotation of the fan blades will blow air to cool the sensor body. Through the above structure, the equipment can be cooled down, thereby improving the service life of the equipment.

[0014] As a preferred embodiment of the present invention, the cleaning assembly includes a filter screen fixedly installed on the inner side wall of the suction head, and the filter screen is located at the position of the exhaust pipe. An electric push rod is installed on the outer side wall of one side of the suction head. The telescopic end of the electric push rod passes through the side wall of the suction head and extends inward and is connected to a cleaning block. The cleaning block is matched with the suction head.

[0015] By adopting the above technical solution, the filter screen filters out large dust particles, preventing them from clogging the exhaust pipe. When it is necessary to clean the dust on the inner wall of the suction head, the electric push rod is activated. The operation of the electric push rod will drive the cleaning block to move, and the movement of the cleaning block will scrape the dust on the inner wall of the suction head, so that the dust can be discharged from the exhaust pipe.

[0016] As a preferred embodiment of the present invention, the movable component includes a groove formed on the upper end of the base plate, the movable plate is slidably connected in the groove, a lead screw is rotatably connected to the inner wall of the groove, one end of the lead screw passes through the groove wall and extends outward, and the lead screw is threadedly connected to the movable plate.

[0017] By adopting the above technical solution, when it is necessary to adjust the position of the mounting bracket, the lead screw is rotated. The rotation of the lead screw will cause the movable plate to move horizontally through the thread action. The movement of the movable plate will drive the mounting bracket to move. The position of the mounting bracket can be adjusted through the above structure to meet the needs under different conditions, thereby improving the practicality of the device.

[0018] As a preferred embodiment of the present invention, two limiting rods are symmetrically fixedly connected to the inner wall of the chute, the limiting rods are disposed through the movable plate, and the movable plate is slidably connected to the limiting rods.

[0019] By adopting the above technical solution, the rotation of the movable plate is prevented.

[0020] As a preferred embodiment of the present invention, one end of the lead screw is connected to a rotating block.

[0021] By adopting the above technical solution, it is convenient for staff to rotate the lead screw.

When it is necessary to clean the dust on the surface of the sensor body, the motor drives the reciprocating lead screw to rotate. The two reciprocating lead screws rotate simultaneously through the first pulley. The rotation of the reciprocating lead screws causes the two moving blocks to move back and forth horizontally through the thread action. The movement of the moving blocks drives the cleaning frame to move, which in turn drives the brush to move. The brush cleans the dust on the surface of the sensor body. At the same time, the fan is started, and the operation of the fan sucks up dust through the exhaust pipe. The exhaust pipe then absorbs the dust stirred up inside the protective shell through the suction head, preventing the dust from falling back onto the sensor body. Through the above structure, the sensor body can be protected, and the dust on the surface of the sensor body can be cleaned, thereby improving the service life of the equipment and the applicability of the device.

[0024] (2) By setting up a rotating shaft, fan blades and a second pulley, the rotation of the reciprocating screw will drive the rotating shaft to rotate through the second pulley. The rotation of the rotating shaft will drive the fan blades to rotate. The rotation of the fan blades will blow air to cool the sensor body. The above structure can cool the equipment and further improve the service life of the equipment.

[0025] (3) The present invention sets up a filter screen, an electric push rod and a cleaning block, etc. The filter screen filters out large dust particles to prevent large dust particles from clogging the exhaust pipe. When it is necessary to clean the dust on the inner wall of the suction head, the electric push rod is activated. The operation of the electric push rod will drive the cleaning block to move. The movement of the cleaning block will scrape the dust on the inner wall of the suction head so that the dust can be discharged from the exhaust pipe. Attached Figure Description
