Description

Technical Field

[0001] This utility model relates to the field of sensor performance testing, and in particular to a sensor performance testing machine. Background Technology

[0002] A draw-wire displacement sensor, also known as a draw-wire sensor, draw-wire electronic ruler, or draw-wire encoder, is a sophisticated structural design that combines the advantages of angle and linear displacement sensors. It is a sensor with small installation size, compact structure, large measuring stroke, and high accuracy, with strokes ranging from hundreds of millimeters to tens of meters.

[0003] Inclinometers, also known as tilt meters, level meters, or inclinometers, are frequently used to measure changes in the horizontal angle of a system. The evolution of levels from simple bubble levels to electronic levels is a result of advancements in automation and electronic measurement technology. They can be used to measure the inclination of a plane relative to a horizontal position, as well as the parallelism and perpendicularity of two components.

[0004] A search revealed that patent CN116929434A discloses a sensor performance testing machine, comprising a mounting platform, a testing assembly, a clamping assembly, an oscilloscope, and wire clamps. The testing assembly includes a test piece and a driving component. The test piece is movably mounted on the mounting platform and has multiple test holes. The driving component drives the movement of the test piece. The clamping assembly includes a sensor clamp slidably connected to the mounting platform and used to clamp a slotted photoelectric sensor. The sensor clamp can move so that part of the test piece is located in the test slot. The oscilloscope displays and records the test data of the slotted photoelectric sensor. Four wire clamps are provided, each electrically connected to the slotted photoelectric sensor and the oscilloscope.

[0005] Existing equipment limits the jitter displacement of the slotted photoelectric sensor by using a non-rotating clamping component. However, since the two are in a state of relative motion, the clamping component wears on the outside of the slotted photoelectric sensor, causing the slotted photoelectric sensor to be damaged.

[0006] Therefore, it is necessary to provide a sensor performance testing machine to solve the above-mentioned technical problems. Utility Model Content

The front of the placement plate is symmetrically provided with limiting clamps, and the bottom of the front of the placement plate is provided with a support plate. The front of the detection slot and the two limiting clamps are provided with a wire end fixing bracket.

[0012] To achieve the effect of driving the sensor to perform stroke displacement, this utility model provides a sensor performance testing machine. Preferably, the bottom of the placement plate is provided with a sliding support plate, and the bottom end of the sliding support plate is provided with a feed slider. The bottom end of the feed slider extends through a groove opened at the bottom of the detection slot and is connected to a lead screw.

Several function buttons are provided on the top of the industrial computer, and a display screen is provided on the top of the function buttons.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This sensor performance testing machine solves the problem that existing equipment restricts the jitter displacement of slotted photoelectric sensors by using a non-rotating clamping component, but the clamping component wears the outside of the slotted photoelectric sensor and damages the sensor because the two are in relative motion. This is achieved by using a telescopic rod to cooperate with a rotating plate and by using two limiting clamps to cooperate with a support plate.

[0018] This sensor performance testing machine, by setting up a first testing structure that can test rotation and tilt sensors and a second testing structure that can test length and draw wire sensors, solves the problem that existing equipment can only test single rotation sensors, and greatly improves the applicability of the equipment.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 This is a schematic diagram of a preferred embodiment of a sensor performance testing machine provided by this utility model; Figure 2 for Figure 1 The diagram shows the internal structure. Figure 3 for Figure 1 The diagram shows the structure of the first test structure. Figure 4 for Figure 3 The diagram shows the structure of the turntable. Figure 5 for Figure 1 The schematic diagram of the second test structure shown includes a sensor performance tester, including a device frame 1. A test slot 2 is provided on one side of the front of the device frame 1. A first test structure 3 is provided on one side of the inside of the test slot 2, and a second test structure 4 is provided on the other side of the inside of the test slot 2.

[0027] The first test structure 3 includes a hydraulic cylinder 302 installed inside the equipment box 5. The top of the hydraulic cylinder 302 extends through the test slot 2 via an inserted hydraulic rod and is movably mounted on a rotating plate 301. The front of the rotating plate 301 is rotatably mounted on the test slot 2. A rotary motor mounting plate 303 is fixedly mounted on the rear end of the top of the rotating plate 301. A telescopic rod 305 extends through the front of the rotary motor mounting plate 303. A rotary motor 304 is inserted into the rear end of the telescopic rod 305 and is fixedly mounted on the rotary motor mounting plate 303. An abutment head 306 is provided on the front of the telescopic rod 305. A turntable mounting plate 307 is provided on the front top of the rotating plate 301, and a turntable 308 is rotatably mounted on the back of the turntable mounting plate 307.

[0028] It should be noted that: when the telescopic rod 305 extends or retracts, it controls the contact head 306 to approach the turntable 308 and clamp the rotation and tilt sensor to be tested. The hydraulic cylinder 302 controls the rotating plate 301 at the top of the hydraulic rod to rotate, thereby changing the tilt angle of the rotation and tilt sensor. Subsequently, the rotary motor 304 controls the telescopic rod 305 to rotate, causing the contact head 306 to rotate and change the rotation and tilt sensor on the turntable 308, thereby detecting the rotation and tilt performance of the rotation and tilt sensor.

[0029] In the specific implementation process, refer to Figure 3 and Figure 4 As shown, a centering groove 309 is provided at the bottom of the back of the turntable 308. A centering support plate 3011 is slidably arranged inside the centering groove 309. The top of the centering support plate 3011 is connected to the top of the centering groove 309 by a spring 3010.

[0030] It should be noted that: the rotation and tilt sensors are placed on the centering plate 3011, and then the centering plate 3011 is manually moved to the center. The spring 3010 controls the centering plate 3011 to stay in the original position, so that the telescopic rod 305 can control the contact head 306 to hold the rotation and tilt sensors.

[0031] In the specific implementation process, refer to Figure 2 and Figure 5 As shown, the second test structure 4 includes a placement plate 401 placed inside the test slot 2. The front of the placement plate 401 is symmetrically provided with limiting clamps 402. The bottom of the front of the placement plate 401 is provided with a support plate 403. The front of the test slot 2 and the two limiting clamps 402 are provided with a wire end fixing bracket 409.

[0032] It should be noted that the two limiting clamps 402 limit the left and right displacement of the length and pull-wire sensors to prevent them from shaking during displacement. The support plate 403 supports the length and pull-wire sensors from the bottom to ensure placement stability. The wire ends of the length and pull-wire sensors are clipped into the through groove inside the wire end fixing bracket 409 to facilitate subsequent length and pull-wire testing.

[0033] In the specific implementation process, refer to Figure 2 and Figure 4As shown, a sliding support plate 404 is provided at the bottom of the placement plate 401, and a feed slider 405 is provided at the bottom end of the sliding support plate 404. The bottom end of the feed slider 405 extends through the slide groove 1 opened at the bottom of the detection slot 2 and is connected to a lead screw 406. A drive motor 407 is connected to the front of the lead screw 406. The drive motor 407 is fixedly installed in the equipment box 5, and the rear end of the lead screw 406 is rotatably connected to the equipment box 5.

[0034] It should be noted that: the drive motor 407 controls the lead screw 406 to rotate, which drives the feed slider 405 to slide back and forth along the slide groove, carrying length and wire sensors for performance testing.

[0035] In the specific implementation process, refer to Figure 2 and Figure 4 As shown, two limiting sliders 408 are symmetrically arranged at the bottom of the sliding tray 404. The bottom ends of the two limiting sliders 408 are slidably arranged in the corresponding sliding grooves at the bottom of the detection slot 2.

[0036] It should be noted that the bottom ends of the two limit sliders 408 are slidably set in the corresponding slide grooves at the bottom of the detection slot 2. The cooperation between the two limit sliders 408 and the two slide grooves 2 keeps the sliding support plate 404 from wobbling left and right.

[0037] In the specific implementation process, refer to Figure 1 and Figure 2 As shown, the equipment box 5 is located at the bottom of the equipment frame 1, and two boxes 6 are symmetrically rotated on the front of the equipment box 5.

[0038] In the specific implementation process, refer to Figure 1 and Figure 2 As shown, a computer control structure 7 is provided on one side of the front of the equipment rack 1. The computer control structure 7 includes an industrial computer 701 provided on one side of the front of the equipment rack 1. Several function buttons 703 are provided on the top of the industrial computer 701, and a display screen 702 is provided on the top of the several function buttons 703.

[0039] It should be noted that: several function buttons 703 electrically control the industrial computer 701 to perform corresponding operations. The industrial computer 701 is electrically connected to rotation, tilt and length / pull-wire sensors by wires, and transmits the test data to the display screen 702 for display.

[0040] The working principle of the sensor performance testing machine provided by this utility model is as follows:

[0041] In use, the rotation and tilt sensors are placed at the rear end of the turntable 308. Spring 3010 controls the centering plate 3011 to move upwards along the centering groove 309, displacing the rotation and tilt sensors to the center of the turntable 308. Telescopic rod 305 extends and retracts, controlling the contact head 306 to approach the turntable 308 and clamp the rotation and tilt sensors to be tested. Hydraulic cylinder 302 controls the rotating plate 301 at the top of the hydraulic rod to rotate, changing the tilt angle of the sensors. Then, rotary motor 304 controls the telescopic rod 305 to rotate, causing the contact head 306 to rotate along with the rotation and tilt sensors on the turntable 308, thus detecting the rotation and tilt performance of the sensors. Length and drawwire sensors are then inserted from top to bottom. Between two limiting clamps 402, the two limiting clamps 402 restrict the left and right displacement of the length and pull-wire type sensors to avoid the problem of shaking during displacement. The support plate 403 supports the length and pull-wire type sensors from the bottom to ensure placement stability. The wire end of the length and pull-wire type sensors is clamped into the through groove inside the wire end fixing bracket 409. The drive motor 407 controls the lead screw 406 to rotate, driving the feed slider 405 to slide back and forth along the slide groove to carry the length and pull-wire type sensors for performance testing. The industrial control computer 701 is electrically connected to the rotation and tilt type sensors and the length and pull-wire type sensors through wires, and transmits the test data to the display screen 702 for display. Several function buttons 703 electrically control the industrial control computer 701 to perform corresponding operations.
