Description

Technical Field

[0001] The utility model belongs to the technical field of testing devices, and particularly relates to a device for testing an angle sensor. Background Art

[0002] An angle sensor is a sensing device used to detect angles and is widely applied in multiple fields and scenarios, including but not limited to industrial machinery, construction machinery, construction equipment, petrochemical equipment, medical equipment, aerospace instruments, national defense industry, automotive electronics, automated robots, motion control, rotation and control of rotating motors, etc. For example, in the automotive field, when a driver needs to drive uphill, the system uses a slope sensor (an angle sensor) to detect the road slope and feedback it to the ECU (Electronic-Control-Unit). Through the slope sensor, the ECU can calculate the vehicle mass more precisely, optimize the starting gear and driving gear, improve the shifting comfort of the transmission and reduce fuel consumption. In addition, the information of the slope sensor is crucial for the vehicle to maintain stability and safety in the case of a large slope. Especially when driving uphill, through strategies such as delaying gear upshifts, it helps the vehicle better cope with slope changes and avoid dangerous situations such as vehicle skidding or backing. Another example is that angle sensors are usually installed in fuel injection type motorcycles. When the angle sensor detects a certain tilt angle value, it will send an alarm signal to the ECU, and the ECU will cut off the working circuit and fuel supply channel of the fuel injection system according to the received alarm signal, interrupt the power output of the engine to ensure the safety of the vehicle.

[0003] It can be seen that whether the angle sensor can provide accurate measurement results is very important. To ensure that the angle sensor can provide correct tilt angle information, it is necessary to comprehensively detect it in various postures before using the angle sensor. However, the existing test tooling has a single angle adjustment and cannot comprehensively judge whether the data output by the angle sensor is correct.

[0004] Therefore, there is an urgent need to propose a device for testing an angle sensor to solve the above problems. Summary of the Utility Model

[0009] The device for testing an angle sensor of the present utility model realizes the adjustment of the inclination posture of the test piece by connecting the test piece to a support plate whose inclination posture can be adjusted.

The support plate is connected to a wire-winding motor through a traction rope, and the wire-winding motor winding the traction rope can realize the adjustment of the elongation of the traction rope. According to the preset posture information, the elongation of one or more traction ropes is adjusted, so that the posture of the support plate changes, and thus the support plate drives the test piece to tilt. By comparing the posture information output by the test piece with the preset posture information, it is judged whether the data output by the test piece is correct. This posture testing tooling is convenient to operate, does not require manual adjustment of the angle of the test piece, can adjust the test piece at multiple angles, the measurement is more comprehensive, and the test efficiency is high.

[0030] Figure 1Schematically shown is a device for testing an angle sensor when the support plate 300 according to an embodiment of the present utility model is in a horizontal state. Figure 2 Schematically shown is a device for testing an angle sensor when the support plate 300 according to an embodiment of the present utility model is in an inclined state. As Figure 1 and 2 shown, the present utility model provides a device for testing an angle sensor. This tooling is used to adjust the attitude of the workpiece to be measured 10, and it includes a mounting frame 100 and a support plate 300. A plurality of wire-winding motors 200 are provided on the mounting frame 100. The wire-winding motor 200 is connected with a traction rope 210. The wire-winding motor 200 is used to adjust the elongation of the traction rope 210. The support plate 300 is connected to the mounting frame 100 through the traction rope 210, and the support plate 300 is used to connect the workpiece to be measured 10.

[0031] The above device for testing an angle sensor realizes the adjustment of the inclined attitude of the workpiece to be measured 10 by connecting the workpiece to be measured 10 to the support plate 300 with an adjustable inclined attitude. The workpiece to be measured 10 can be a slope sensor, an ECU integrated with a slope sensor, an inclination sensor, or other types of angle sensors. The support plate 300 is connected to the wire-winding motor 200 through the traction rope 210. The wire-winding motor 200 winding the traction rope 210 can realize the adjustment of the elongation of the traction rope 210. According to the preset attitude information, the elongation of one or more traction ropes 210 is adjusted, so that the attitude of the support plate 300 changes, and thus the support plate 300 drives the workpiece to be measured 10 to incline. By comparing the attitude information output by the workpiece to be measured 10 with the preset attitude information, it is judged whether the data output by the workpiece to be measured 10 is correct. This attitude testing tooling is convenient to operate, does not require manual adjustment of the angle of the workpiece to be measured 10, can adjust the workpiece to be measured 10 at multiple angles, the measurement is more comprehensive, and the testing efficiency is high.

[0032] Further, the mounting frame 100 includes at least two transverse guide rails 110. At least two transverse moving motors 400 are provided on each transverse guide rail 110. The transverse moving motor 400 can reciprocate along the transverse guide rail 110. Each transverse moving motor 400 is fixedly connected with a wire-winding motor 200. As Figure 1 shown, the transverse guide rail 110 is arranged along the X-axis direction. It can be understood that when the transverse moving motor 400 reciprocates along the transverse guide rail 110, it can drive the wire-winding motor 200 to move, and further move the position of the traction rope 210, so as to adjust the inclination angle of the support plate 300. Optionally, the transverse moving motor 400 can be a stepping motor, which can accurately move to a specified position, so that the inclination angle of the support plate 300 can be adjusted stably and accurately, and a comprehensive test can be realized.

[0033] In this embodiment, there are two transverse guide rails 110, and two transverse moving motors 400 are arranged on each transverse guide rail 110. That is, the total number of transverse moving motors 400 is four, and the numbers of winding motors 200 and traction ropes 210 are both four. The four traction ropes 210 are respectively located at the four corners of the support plate 300. In other embodiments, the number of transverse guide rails 110 can also be three, four, five, etc., and the number of transverse moving motors 400 on each transverse guide rail 110 can also be three, four, five, etc. By increasing the numbers of winding motors 200 and traction ropes 210, the shaking of the support plate 300 can be reduced, so that the test piece 10 can be easily kept in a stable state.

[0034] Further, the mounting frame 100 includes two longitudinal guide rails 120 arranged oppositely. Longitudinal moving motors 500 are fixedly connected to both ends of each transverse guide rail 110. The longitudinal moving motors 500 are connected to the longitudinal guide rails 120 and can reciprocate along the longitudinal guide rails 120. As Figure 1 shown, the longitudinal guide rails 120 are arranged along the Y-axis direction and are perpendicular to the transverse guide rails 110. By adjusting the positions of the longitudinal moving motors 500, the distance between the transverse guide rails 110 can be adjusted. The transverse guide rails 110 drive the traction ropes 210 to move, and then the attitude of the support plate 300 can be adjusted. The longitudinal moving motors 500 can be stepper motors, so that they can accurately move to the specified positions, and thus the tilt angle of the support plate 300 can be stably and accurately adjusted to achieve comprehensive testing.

[0035] Further, the mounting frame 100 includes a frame structure 130, and the longitudinal guide rails 120 are connected to the top of the frame structure 130. Optionally, the frame structure 130 can be placed on a flat ground or a working platform. By arranging the longitudinal guide rails 120 at the top of the frame structure 130, the transverse guide rails 110, the transverse moving motors 400 and the winding motors 200 are all located at the top of the frame structure 130. Therefore, enough space can be provided for the elongation of the traction ropes 210, which is convenient for adjusting the attitude of the support plate 300.

[0036] Further, the frame structure 130 includes a vertical direction ( Figure 1A plurality of support rods 131 are arranged in the Z-axis direction (in the middle). Adjacent support rods 131 are connected by connecting beams 132, and the longitudinal guide rail 120 is connected to the tops of all the support rods 131. The support rods 131 and the connecting beams 132 can provide stable support for the components at the top of the frame structure 130 and do not block the line of sight. The operator can intuitively see the attitude of the support plate 300 and the process of attitude adjustment. In this embodiment, the number of support rods 131 is four, and the four support rods 131 are arranged in a rectangular array. Each two support rods 131 are fixedly connected by a connecting beam 132. The four connecting beams 132 are all arranged at the tops of the support rods 131 and are connected to form a rectangular frame. In other embodiments, the connecting beam 132 can also be located at the middle position of the support beam. To increase the strength of the structure, the number of support rods 131 can be five, six, seven, etc., or multiple connecting beams 132 can be arranged between adjacent two support rods 131, and the multiple connecting beams 132 are arranged at intervals in the vertical direction. Optionally, the support rods 131 and the connecting beams 132 can be angle steels.

[0037] Further, fixing members 140 are respectively arranged at both ends of the longitudinal guide rail 120, and the longitudinal guide rail 120 is connected to the tops of the support rods 131 through the fixing members 140. In this embodiment, since the support beam is located at the top of the support rods 131, by arranging the fixing members 140, a certain space can be provided between the longitudinal guide rail 120 and the support beam, which is convenient for the installation and normal operation of the longitudinal movement motor 500.

[0038] Further, the fixing member 140 includes a fixing plate 141 and a reinforcing rib 142. The longitudinal guide rail 120 is connected to the center of the fixing plate 141. The bottom of the fixing plate 141 is connected to the support rod 131. Two adjacent sides of the reinforcing rib 142 are respectively connected to the fixing plate 141 and the support rod 131. Connecting the fixing plate 141 and the support rod 131 by using the reinforcing rib 142 can increase the connection strength between the fixing plate 141 and the support rod 131 and prevent the fixing plate 141 from breaking after long-term operation.

[0039] In some embodiments, referring to Figure 2 and Figure 3 , the support plate 300 is a rectangular plate-like structure. In other embodiments, the support plate 300 can be circular, kidney-shaped, square, etc. No specific limitation is made here as long as it has enough area to install the test piece 10 and the traction rope 210.

[0040] Further, the support plate 300 is provided with mounting holes 310 for passing through locking members, and the test piece 10 can be fixedly connected to the support plate 300 through the locking members. In one embodiment, the mounting holes 310 are elongated holes, the locking members are bolts, and through holes allowing the bolts to pass through are provided on the test piece 10. During assembly, the bolts pass through the through holes on the test piece 10 and the mounting holes 310 on the support plate 300 in sequence, and nuts are tightened on the bolts. In another embodiment, the mounting holes 310 can be threaded holes, the locking members are screws, and through holes allowing the screws to pass through are provided on the test piece 10. During assembly, the screws pass through the through holes on the test piece 10 and are tightened in the mounting holes 310 on the support plate 300. In some other embodiments, the locking members can also be straps, and the straps pass through the mounting holes 310 and bind the test piece 10 to the support plate 300.

[0041] Further, a positioning groove for placing the test piece 10 is provided on the support plate 300. Preferably, the positioning groove is a T-shaped groove, and its specific shape is set according to the shape of the test piece 10, so as to effectively fix the test piece 10 and prevent relative movement between the test piece 10 and the support plate 300.

[0042] The working process of the device for testing the angle sensor provided in this embodiment is as follows:

[0043] Determine the preset tilt angle of the test piece 10, input the tilt angles of the test piece 10 on the X, Y, and Z axes through a computer, and after computer calculation, convert the tilt angles into the movement step lengths of the lateral movement motor 400 and the longitudinal movement motor 500 and the rotation step length of the wire winding motor 200. Each motor starts to move cooperatively to control the support plate 300 to tilt. At the same time, the support plate 300 drives the test piece 10 to tilt. When each motor moves in place, the computer emits a beeping sound to prompt the operator to record the measurement data of the test piece 10. By observing whether the measurement data of the test piece 10 is the same as the preset tilt angle, it can be judged whether the measurement data of the test piece 10 is accurate. By adjusting the tilt angle of the test piece 10 multiple times, the test piece 10 can be comprehensively tested. The conversion between the tilt angles of the test piece 10 on the X, Y, and Z axes and the motor step lengths is a conventional technical means in the art and will not be elaborated here.

[0044] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
