DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not simply refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. For example, the fixed connection / installation can be connected by screws, bolts and other accessories, or it can be directly connected by welding, bonding and other methods. The various technical features in the invention can be combined interchangeably without conflicting with each other.

[0028] Reference Figure 1 and Figure 2An embodiment of the present invention provides a sensor functional test device for testing the function of a sensor and the accuracy of detection data, comprising a base box 1 and an upper box 2, wherein the base box 1 is provided with a rotational motion test component 4, a linear motion test component and two chuck frame components 3, the two chuck frame components 3 are respectively provided corresponding to the rotational motion test component 4 and the linear motion test component, the rotational motion test component 4 is used to drive a detection block 43 (the detection block 43 refers to an object simulating a part of a device to be detected) to rotate, the linear motion test component is used to drive the detection block 43 to perform linear motion, and the chuck frame component 3 is used to clamp a sensor 38 to be tested.

[0029] The upper box body 2 includes a frame body and a frame shield, which is used to cover the rotary motion test component 4, the linear motion test component and the chuck frame component 3, thereby isolating the rotary motion test component 4, the linear motion test component and the chuck frame component 3 from the external environment, avoiding environmental interference and improving the accuracy of the test.

[0030] The upper box body 2 is provided with a speed and torque display 8, a button panel 7 and a touch screen 9. The start and stop of the test equipment are operated by the button panel 7. The speed and torque display 8 is electrically connected to the rotary motion test component 4, and is used to display the speed, torque and other information of the detection block 43. The touch screen 9 is electrically connected to the sensor 38 under test, and is used to display the detection data of the sensor 38 under test. The linear motion test component is also electrically connected to the touch screen 9, and the touch screen 9 is used to control the speed and acceleration of the linear motion of the detection block 43 driven by the linear motion test component.

[0031] In this embodiment, for sensors that detect linear motion, a detection block 43 that matches the parts of the device to be detected can be designed, and the detection block 43 is fixed on the linear motion test assembly. The corresponding linear motion acceleration and deceleration, running speed, etc. are output to the linear motion test assembly through the touch screen 9 (built-in device control system), thereby driving the detection block 43 to move; the sensor to be tested 38 is fixed on the chuck frame assembly 3 corresponding to the linear motion test assembly, and the result output by the sensor to be tested 38 on the touch screen 9 is compared with the set motion to measure whether the accuracy and functionality of the linear sensor meet the requirements.

[0032] For sensors that detect rotational motion, the sensor 38 to be tested can be fixed on the chuck frame assembly 3 corresponding to the rotational motion test assembly 4. By adjusting the position of the sensor 38 to be tested so that it is aligned with the detection block 43 on the rotational motion test assembly 4, the set rotational motion is input into the rotational motion test assembly 4 through the touch screen 9 (built-in device control system) to drive the detection block 43 to move. By comparing the result output by the sensor 38 to be tested on the touch screen 9 with the set motion (the speed and torque display 8 can display the speed and torque data of the detection block 43 driven by the rotational motion test assembly 4), it is measured whether the accuracy and functionality of the rotational sensor meet the requirements.

[0033] In this embodiment, refer to Figure 3 The chuck frame assembly 3 includes a base 31, a clamp 37, a vertical adjustment member and a horizontal adjustment member. The clamp 37 is installed at the movable end of the horizontal adjustment member, and the horizontal adjustment member is installed at the movable end of the vertical adjustment member. The vertical adjustment member is installed on the base box 1 through the base 31, and the clamp 37 is used to clamp the sensor 38 to be tested. In this way, the height of the sensor 38 to be tested is adjusted by the vertical adjustment member, and the position of the sensor 38 to be tested in the horizontal direction is adjusted by the horizontal adjustment member, so that the sensor 38 to be tested can be centered on the detection block 43, thereby improving the detection effect of the sensor 38 to be tested on the detection block 43.

[0034] Further, the fixture 37 includes a chuck base 371, a guide shaft 372, a clamping plate 375, and a fine-tuning member. The chuck base 371 has a 'C'-shaped structure and includes a vertical plate, a top plate, and a bottom plate. The top plate and the bottom plate are respectively vertically connected to both sides of the vertical plate. There are two guide shafts 372, and the two guide shafts 372 are arranged in parallel between the top plate and the bottom plate of the chuck base 371. The clamping plate 375 is slidably connected to the two guide shafts 372 to ensure that the clamping plate 375 slides stably along the direction of the guide shaft 372 without deflection. A clamping space is formed between the clamping plate 375 and the bottom plate of the chuck base 371. Rubber pads 376 are provided on both sides of the clamping plate 375 opposite to the bottom plate of the chuck base 371 to prevent the sensor under test 38 from being clamped and damaged. The fine-tuning member is used to drive the clamping plate 375 to move to adjust the size of the clamping space. Specifically, the fine-tuning member includes a screw rod 373 rotatably provided on the chuck base 371. The screw rod 373 is located between the two guide shafts 372. The screw rod 373 passes through the clamping plate 375 and is threadedly connected to the clamping plate 375. Both ends of the screw rod 373 are rotatably connected to the top plate and the bottom plate respectively, and a fine-tuning handwheel 374 is connected to the end of the screw rod 373 located on the top plate. When the sensor under test 38 is placed in the clamping space, rotate the fine-tuning handwheel 374 to drive the screw rod 373 to rotate. When the screw rod 373 rotates, it drives the clamping plate 375 to move towards the sensor under test 38, so as to cooperate with the bottom plate of the chuck base 371 to clamp the sensor under test 38. When it is necessary to remove the sensor under test 38, rotate the fine-tuning handwheel 374 in the reverse direction to drive the clamping plate 375 to move away from the sensor under test 38, and when they no longer clamp the sensor under test 38, the sensor under test 38 can be removed.

[0035] Further, the vertical adjustment member includes a vertical adjustment shaft 32 and a clamping block 33. The bottom end of the vertical adjustment shaft 32 is fixedly connected to the base 31. The clamping block 33 is provided with a first adjustment hole and a first locking handle 34. The vertical adjustment shaft 32 is slidably connected in the first adjustment hole. The first locking handle 34 is used to lock or unlock the vertical adjustment shaft 32 and the clamping block 33. When it is necessary to adjust the height of the sensor under test 38, open the first locking handle 34 so that the clamping block 33 can move on the vertical adjustment shaft 32, thereby adjusting the height of the sensor under test 38, and then close the first locking handle 34 to fix the height of the sensor under test 38. Additionally, when the first locking handle 34 is opened, the clamping block 33 can also be rotated along the circumferential direction of the vertical adjustment shaft 32 ( Figure 3 in the R-axis direction) to adjust the position and angle of the sensor under test 38 in the horizontal direction.

[0036] The horizontal adjustment member includes a horizontal adjustment shaft 36, and the clamping block 33 is provided with a second adjustment hole and a second locking handle 35. The horizontal adjustment shaft 36 is slidably connected to the second adjustment hole, and the second locking handle 35 is used to lock or unlock the horizontal adjustment shaft 36 and the clamping block 33. The end of the horizontal adjustment shaft 36 is fixedly connected to the clamping head seat 371. When it is necessary to adjust the horizontal position of the sensor 38 to be measured, the second locking handle 35 is opened to move the vertical adjustment shaft 32 in the clamping block 33, thereby adjusting the horizontal position of the sensor 38 to be measured, and then the second locking handle 35 is closed to fix the sensor 38 to be measured in this position; in addition, when the second locking handle 35 is opened, the horizontal adjustment shaft 36 can also be rotated in the clamping block 33 (the rotation direction is Figure 3 W-axis direction), thereby adjusting the position and angle of the sensor 38 under test in the vertical direction.

[0037] Specifically, refer to Figure 4 The clamp block 33 is an elastic clamp block 33, and the first adjustment hole and the second adjustment hole are both connected with an adjustment groove. In a normal state, the vertical adjustment axis 32 and the horizontal adjustment axis 36 can slide in the first adjustment hole and the second adjustment hole respectively. When it is necessary to lock the vertical adjustment axis 32 and the clamp block 33, the first locking handle 34 is used to drive the clamp block 33 to deform so that the width of the adjustment groove connected to the first adjustment hole becomes smaller, thereby fixing the vertical adjustment axis 32 in the first adjustment hole. Similarly, when it is necessary to lock the horizontal adjustment axis 36 and the clamp block 33, the second locking handle 35 is used to drive the clamp block 33 to deform so that the width of the adjustment groove connected to the second adjustment hole becomes smaller, thereby fixing the horizontal adjustment axis 36 in the second adjustment hole.

[0038] Specifically, the first locking handle 34 and the second locking handle 35 both include a locking screw and a handle, the handle is fixedly connected to the head of the locking screw, the clamping block 33 is located on both sides of the adjustment groove, respectively, the elastic part and the fixed part, the locking screw can be screwed into the threaded hole on the elastic part and threadedly connected to the threaded hole on the fixed part. When the handle is rotated to drive the locking screw to be screwed in toward the fixed part, the head of the locking screw will press against the elastic part of the clamping block 33 to cause the elastic part to deform toward the adjustment groove, thereby reducing the size of the first / second adjustment hole connected to the adjustment groove, thereby realizing the locking of the horizontal adjustment axis 36 or the vertical adjustment axis 32, and the handle can be rotated in the opposite direction to unlock.

[0039] In this embodiment, refer to Figure 5The rotary motion test assembly 4 includes a mounting seat 41, a motor 45, a mounting shaft 42, and an encoder 47. The mounting seat 41 is fixed on the base box 1, the mounting shaft 42 is rotatably connected to the mounting seat 41, the motor 45 is fixed to the mounting seat 41 through a motor seat 44, and the main shaft of the motor 45 is connected to one end of the mounting shaft 42 through a coupling 46, the encoder 47 is connected to the other end of the mounting shaft 42 away from the motor 45, and the detection block 43 is installed on the mounting shaft 42. The motor 45 drives the mounting shaft 42 to rotate, thereby driving the detection block 43 to rotate, and the encoder 47 accurately controls and feeds back the movement of the detection block 43, and outputs the result on the speed torque display 8.

[0040] Specifically, refer to Figure 7 The detection surface of the detection block 43 is an arc surface with irregular transitions of different radii (with the axis of the mounting shaft 42 as the center), that is, when the detection block 43 rotates, the distance between the detection block 43 and the fixed sensor 38 to be detected can be changed (such as S1 to S2), so as to achieve a change in the distance of the position to be detected to compare the value read on the sensor 38 to be detected.

[0041] More specifically, see Figure 6 The detection block 43 includes a connecting portion 432, a fixing portion 431 and a detection portion 433. The connecting portion 432 and the fixing portion 431 are detachably connected by screws. A first semicircular groove is provided on a side of the connecting portion 432 close to the fixing portion 431, and a second semicircular groove is provided on a side of the fixing portion 431 close to the connecting portion 432. When the connecting portion 432 and the fixing portion 431 are connected as a whole, the first semicircular groove and the second semicircular groove form a mounting circular hole 436, and the mounting circular hole 436 is sleeved on the mounting shaft 42. The connecting portion 432 and the fixing portion 431 are locked by screws to complete the installation of the detection block 43. The detection part 433 is integrally formed on the side of the connecting part 432 away from the fixing part 431. The detection part 433 is fan-shaped as a whole. A hole 435 is provided on the detection part 433 to reduce its weight. The side of the detection part 433 away from the connecting part 432 is an arc surface 434, and the center of the arc surface 434 is at a distance from the center of the mounting hole 436. That is to say, when the detection block 43 rotates with the mounting shaft 42, the motion trajectory of the arc surface 434 of the detection part 433 forms an irregular motion trajectory based on the axis of the mounting shaft 42, thereby changing the distance between the detection block 43 and the fixed sensor 38 to be measured.

[0042] In this embodiment, refer to Figure 1The linear motion test assembly includes a first linear module 5 and a second linear module 6. The length of the second linear module 6 is greater than that of the first linear module 5. Both the first linear module 5 and the second linear module 6 adopt a linear motor 45. The specification of the first linear module 5 is smaller than that of the second linear module 6. According to the required installation size of the detection block 43, a first linear module 5 or a second linear module 6 of appropriate size is selected, and the detection block 43 is installed on the mover of the linear motor 45. The set linear motion acceleration and deceleration, running speed, etc. are output to the linear motor 45 to drive the detection block 43 to move.

[0043] In this embodiment, a three-color alarm light 10 is provided on the upper box body 2, and the three-color alarm light 10 is electrically connected to the touch screen 9. The three-color alarm light 10 adopts red, yellow and green colors. The result output by the measured sensor 38 on the touch screen 9 is compared with the set motion. A green light is emitted when the specified accuracy is reached, a yellow light is emitted when there is a certain error, and a red light is emitted when a device system fails.
