Description

Technical Field

[0001] The utility model belongs to the technical field of testing, in particular to a sensor simulation tester. Background Art

[0002] A sensor is a detection device that can sense the information being measured and can convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording and control. Angle sensor is a type of sensor. Before using the sensor, it will be subjected to random inspection simulation test, so a sensor simulation tester will be used. Traditional testers will use motors to adjust the angle, but if only one motor is used for adjustment, the test range is limited to a narrow range.

[0003] After searching, the Chinese patent document (authorization announcement number CN218211264U) discloses an angle sensor accuracy test device, a flat plate and a limit ring at the top of the flat plate, a protective frame installed at the bottom of the flat plate, a base connected to the bottom of the flat plate, a motor connected to the inner bottom wall of the protective frame, a shaft connected to the output end of the motor, a movable disk connected to the top of the shaft, a driving member provided at the top of the movable disk, a stabilizing cylinder connected to the top of the movable disk, a lifting rod slidably connected to the inner side wall of the stabilizing cylinder, and a stabilizing mechanism provided at the top of the lifting rod. The angle sensor accuracy test device stabilizes the angle sensor at the top of the lifting rod through the coordinated use of bolts and limit blocks. When the motor is running, the shaft drives the movable disk to rotate, and the stabilizing cylinder drives the lifting rod to rotate, thereby adjusting the rotation of the angle sensor stabilized at the top of the lifting rod. The above structure achieves the effect of facilitating the rotation adjustment of the angle sensor. Although the circumferential direction test is possible, there is no simulation test of the deflection capability. Utility Model Content

[0004] The utility model aims to provide a sensor simulation tester to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sensor simulation tester, comprising a counterweight plate and a support plate arranged above the counterweight plate for supporting a sensor, two electric push rods are installed on the top of the support plate, the side of the moving part of the electric push rod is connected with a fixing plate for fixing the sensor, the top of the counterweight plate is connected with a first lifting ear, the inner wall of the first lifting ear is rotatably connected with a first rotating rod, and the outer wall of the first lifting ear is installed with a first forward and reverse motor that provides simulation test power for the first rotating rod;

[0006] The outer periphery of the first rotating rod is fixedly connected with a second lifting ear, the inner wall of the second lifting ear is rotatably connected with a second rotating rod connected to the support plate, and the outer wall of the second lifting ear is installed with a second forward and reverse motor that provides simulation test power for the second rotating rod.

[0007] As a preferred embodiment, the vertical inner wall of the first hanging ear and the vertical inner wall of the second hanging ear are both bonded with scale line paper, and the outer peripheries of the first rotating rod and the second rotating rod are both connected with marking plates.

[0008] As a preferred embodiment, a level is connected to the outer circumference of the first rotating rod and the second rotating rod.

[0009] As a preferred embodiment, a protection box with an opening at the bottom is arranged on the outer periphery of the counterweight plate, and the protection box is connected and fixed to the counterweight plate by four fixing threaded rods.

[0010] As a preferred embodiment, a non-slip pad is bonded to the bottom end of the counterweight plate.

[0011] As a preferred embodiment, the top and one of the side surfaces of the protection box are rotatably connected with a movable plate, and a perspective window for observing the sensor simulation test process is embedded in the side surface of the movable plate.

[0012] As a preferred embodiment, a shoulder strap is connected to the outer periphery of the protection box, and an adjustment buckle for adjusting the use length of the shoulder strap is installed on the shoulder strap.

[0013] As a preferred embodiment, a rubber pad with a protective function is bonded to one of the side surfaces of the protection box.

[0014] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0015] The sensor simulation tester can adjust the first forward and reverse motor or the second forward and reverse motor separately during the test to realize the unidirectional deflection test. If the first forward and reverse motor and the second forward and reverse motor are adjusted in coordination, the omnidirectional deflection test can be realized, thereby simulating the expression of the sensor in actual use.

[0016] When the sensor simulation tester is not in use, the protection box can protect the structure and instruments above the counterweight plate, and the shoulder strap can be used to facilitate the overall movement and carrying. When carrying, the rubber pad can protect the carrier and reduce the impact of the protection box and the fixed threaded rod on the carrier. When in use, the protection box can be removed, or only the two movable plates can be opened for operation;

[0017] The sensor simulation tester can not only perform deflection testing, but also provide protection and portability. BRIEF DESCRIPTION OF THE DRAWINGS

During the test, the first forward and reverse motor 7 or the second forward and reverse motor 10 can be adjusted separately to realize a unidirectional deflection test. If the first forward and reverse motor 7 and the second forward and reverse motor 10 are adjusted in coordination, a full-range deflection test can be realized, thereby simulating the expression of the sensor during actual use.

[0030] In order to know the test results and to match the expression comparison data of the sensor, scale paper is glued to the vertical inner wall of the first hanging ear 5 and the vertical inner wall of the second hanging ear 8, and the outer peripheries of the first rotating rod 6 and the second rotating rod 9 are connected with marking plates 11, and the outer peripheries of the first rotating rod 6 and the second rotating rod 9 are connected with spirit levels 12.

[0031] In order to facilitate carrying and protect, a protection box 13 with an opening at the bottom is provided on the periphery of the counterweight plate 1, and the protection box 13 is connected and fixed to the counterweight plate 1 by four fixed threaded rods 14, and an anti-slip pad 15 is bonded to the bottom end of the counterweight plate 1, and a movable plate 16 is rotatably connected to the top and one of the sides of the protection box 13, and the movable plate 16 is connected and fixed to the protection box 13 by a lock, and a perspective window for observing the sensor simulation test process is embedded in the side of the movable plate 16, and a shoulder strap 17 is connected to the periphery of the protection box 13. When carried to the designated position, the whole is placed on a horizontal table, and then the movable plate 16 is opened or the fixed threaded rod 14 is removed, and then the sensor to be tested is placed on the support plate 2, and an adjustment buckle for adjusting the use length of the shoulder strap 17 is installed on the shoulder strap 17, and a rubber pad 18 with a protective function is bonded to one of the sides of the protection box 13, and the carrier uses the shoulder strap 17 to carry it, and at this time, one side of the rubber pad 18 is against the body of the carrier, thereby reducing the influence of the fixed threaded rod 14 on the carrier.

The control method of the present invention is controlled by a controller, and the control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0033] How it works

[0034] The sensor simulation tester is carried by the carrier using a shoulder strap 17, at which time one side of the rubber pad 18 is against the carrier's body. When the carrier is carried to the designated position, the whole is placed on a horizontal table, and then the movable plate 16 is opened or the fixed threaded rod 14 is removed, and then the sensor to be tested is placed on the support plate 2, and then the two electric push rods 3 are controlled to extend synchronously, so that the fixed plate 4 fixes the sensor;

[0035] During the test, the first forward and reverse motor 7 or the second forward and reverse motor 10 can be adjusted individually to achieve a unidirectional deflection test. If the first forward and reverse motor 7 and the second forward and reverse motor 10 are adjusted in coordination, a full-range deflection test can be achieved, thereby simulating the expression of the sensor during actual use.
