Description

Technical Field

[0001] This application relates to the field of speed sensor production and testing technology, and in particular to a speed sensor speed detection device. Background Technology

[0002] The speed sensor uses a magnetoresistive sensor as its sensing element and is a new type of speed sensor. Its core component is the magnetoresistive sensor, further enhanced by a new signal processing circuit that reduces noise and improves functionality. Comparison with the output waveforms of other types of gear speed sensors shows extremely small errors in the measured speed and excellent consistency in linearity. The sensing object is a magnetic or magnetically permeable material, such as magnets, iron, and electrical steel. When the measured object has protrusions (or depressions) on its magnetic or magnetically permeable material, as the object rotates, the sensor outputs a pulse signal related to the rotation frequency, achieving the purpose of speed or displacement detection. The speed of the speed sensor is tested after production.

[0003] The existing detection method is to test the speed sensor by simulating its rotational speed. Currently, multiple devices are used to simulate the rotational speed of the speed sensor, and then the data from multiple tests are compared. This method is costly and time-consuming. Utility Model Content

It aims to solve the problem that the existing detection method in the prior art is to test the speed sensor by simulating its rotational speed. Currently, this method involves using multiple devices to simulate the rotational speed of the speed sensor and then comparing the data from multiple tests. This method is costly and time-consuming.

[0005] To achieve the above objectives, this application provides the following technical solution: a speed detection device for a speed sensor, comprising a support body, the support body including a base plate and a vertical plate, a test base and the vertical plate mounted on the top of the base plate, a test mechanism mounted on the top of the test base, the test mechanism including a speed sensor and a signal test component, the speed sensor having a built-in Hall element, a power socket provided on one side of the speed sensor, the signal test component being rotatably connected above the speed sensor, a longitudinal adjustment mechanism mounted on the top of the vertical plate, a fixing installation mechanism mounted at the bottom of the longitudinal adjustment mechanism, a drive mechanism mounted on one side of the fixing installation mechanism, and reinforcement components provided on both sides of the bottom of the test base.

When the signal test piece rotates, the Hall element built into the speed sensor can detect the actual speed of the signal test piece in real time. Then, by comparing it with the actual speed of the driving mechanism, if the two sets of data are inconsistent, it indicates that the speed sensor has a problem and is a defective product.

[0018] By adopting the above technical solution and setting a fixing groove, different U-shaped baffles can be replaced as needed during use. The installation is relatively convenient and easy to use because the connecting bolts are used.

[0019] As a preferred technical solution of this application, the reinforcement component includes a base block, a reinforcement plate is fixedly connected to the top of the base block, and the other end of the reinforcement plate is bolted to the fixing seat.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0026] Reference Figure 1-3 A speed detection device for a speed sensor includes a support body 1, which includes a base plate 101 and a vertical plate 102. A test base 5 and the vertical plate 102 are mounted on the top of the base plate 101. A test mechanism 6 is mounted on the top of the test base 5.

[0030] Working principle: By setting up the bracket body 1, during use, the speed sensor 601 is placed above the test base 5 and powered by an external power supply through the power socket 604. Then, the signal test piece 602 is placed on the speed sensor 601.

In this device, by setting the mounting base 302, the DC speed-regulating motor 401 can drive the transmission rod 402 to rotate during use. When the transmission rod 402 rotates, it drives the U-shaped baffle 404 at the bottom to rotate. The U-shaped baffle 404 will abut against the stop post 603, thereby driving the signal test piece 602 to rotate on top of the speed sensor 601. The operator can adjust the speed of the DC speed-regulating motor 401, which is convenient for testing different speed sensors 601. It is more convenient to use. By setting the fixing base 502, the test base 5 can be replaced according to different speed sensors 601 because the fixing base 502 is threadedly connected to the base plate 101, thus improving the practicality of the device. Meanwhile, by setting up the controller component 7, during use and testing, the drive mechanism 4, longitudinal adjustment mechanism 2 and fixed installation mechanism 3 can be controlled more conveniently, making it easier to adjust the test data and improve the practicality of the device. In addition, by setting up the display screen 8, the detection comparison data can be displayed on the display screen 8 in real time during use, which is convenient for staff to observe and improves the practicality of the device; by setting up the fixing groove 403, different U-shaped baffles 404 can be replaced as needed during use, and the installation is convenient and easy to use by connecting bolts 405; by setting up the base block 901, the two sets of reinforcing components 9 can further fix the two sides of the connecting shaft 501 during use, preventing loosening during rotation and improving the stability of the device.
