Description

Technical Field

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

[0002] Wheel speed sensors are sensors used to measure the rotational speed of a car's tires, and are typically installed on each wheel. They monitor the car's speed by sensing the rotational speed of the wheels and transmit this data to the vehicle's electronic control system. They are important for vehicle stability control, acceleration control, braking adjustment, and fuel consumption management.

[0003] During the production of wheel speed sensors, it is necessary to test whether the sensor's performance meets the requirements. This requires checking whether the gap between the sensor and the target wheel meets the requirements. If the gap is too large, the sensor may fail to detect the target wheel's rotation correctly, leading to measurement errors. Conversely, if the gap is too small, the sensor head may rub against the target wheel, damaging either the sensor or the target wheel. Therefore, ensuring that the end face gap between the sensor head and the target wheel is within the appropriate range is crucial for accurate wheel speed measurement.

[0004] In the existing technology, the gap between the wheel speed sensor and the target wheel is usually measured directly using a feeler gauge. However, the feeler gauge itself is not accurate enough and is greatly affected by the professional level of the measuring personnel. Therefore, the accuracy of the existing technology in detecting the gap between the wheel speed sensor and the target wheel is poor, and the detection process is relatively cumbersome. Utility Model Content

[0005] The purpose of this invention is to solve the problem of poor accuracy in detecting the gap between the wheel speed sensor and the target wheel in existing technologies. This invention provides a detection device that is simple to operate and can obtain high-precision measurements of the gap between the wheel speed sensor and the target wheel.

[0006] To solve the above-mentioned technical problems, an embodiment of this utility model discloses a detection device, comprising:

[0007] First Installation Department;

[0008] A standard gauge block is detachably mounted on the first mounting part. The standard gauge block includes a first reference surface and a second reference surface arranged opposite to each other along a first direction, and there is a first distance between the first reference surface and the second reference surface.

[0009] The second mounting part is connected to the first mounting part. Along the first direction, the first reference surface is spaced apart from the second mounting part, and the second reference surface is used to form a gap with the side of the target wheel.

[0010] A measuring unit is disposed on the second mounting part. The measuring unit is switchable between a first state and a second state. The measuring unit includes a probe, which is movably disposed on the second mounting part along the first direction. In the first state, the standard gauge block is disposed on the first mounting part, and the probe abuts against the first reference surface to obtain a first reference value. In the second state, the standard gauge block is not disposed on the first mounting part, and the probe is used to abut against the side of the target wheel to obtain a second reference value.

[0011] Using the above technical solution, a standard gauge is used to simulate a sensor (e.g., a wheel speed sensor). The first distance L0 between the first and second reference surfaces of the standard gauge can be determined during the manufacturing process of the standard gauge, and is known data. The measuring part is located in the second mounting part and can switch between a first state and a second state. In the first state, the standard gauge block is located in the first mounting part, and the probe of the measuring part abuts against the first reference surface to obtain the first reference value L1. In the second state, the standard gauge block is not located in the first mounting part, and the probe is used to abut against the side of the target wheel to obtain the second reference value L2. Based on the measured data, subtracting L1 from L2 yields the distance L3 from the first reference surface to the side of the target wheel. This distance includes the first distance L0. Therefore, the gap value from the second reference surface to the side of the target wheel can be obtained by subtracting L0 from L3. There is no need to manually insert a feeler gauge into the gap between the second reference surface and the side of the target wheel. Therefore, it is not affected by the insufficient accuracy of the feeler gauge itself or the professional level of the operator. The operation process is simple and has high measurement accuracy.

[0012] Understandably, in the first state, the measuring unit can also be zeroed at the first reference plane, where L1 = 0 and L2 = L3. In the second state, L2 is the distance L3 from the first reference plane to the side of the target wheel. By subtracting L0 from L2 (L3), the clearance value from the second reference plane to the side of the target wheel can be obtained.

[0013] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a detection device, wherein the measuring unit further includes a third state, and the measuring unit is capable of switching between the first state, the second state and the third state. In the third state, the probe does not abut against the first reference surface and the side of the target wheel.

[0014] By adopting the above technical solution, in the third state, the probe does not come into contact with the first reference surface and the side of the target wheel, that is, the measuring part is in the closed state, which can avoid damage to the probe and extend the service life of the probe.

[0015] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a testing device. The first mounting part includes a mounting groove, which is disposed on the top surface of the first mounting part. The standard gauge block includes a fixing part and a testing part. The fixing part is sleeved around the periphery of the testing part. The testing part passes through the mounting groove. The fixing part abuts against the bottom wall of the mounting groove. Along the second direction, the first reference surface and the second reference surface are disposed on the side of the testing part away from the fixing part.

[0016] By adopting the above technical solution, the fixing part is sleeved around the detection part and abuts against the bottom wall of the mounting groove, which can improve the stability of the standard gauge block on the first mounting part and improve the detection accuracy.

[0017] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a testing device, wherein the second mounting part includes a first connecting plate and a second connecting plate, the first connecting plate extends along a first direction, the second connecting plate extends along a second direction, one end of the second connecting plate is connected to the first mounting part along the second direction, and the other end is connected to the first connecting plate, and the probe is movably mounted on the second connecting plate along the first direction.

[0018] By adopting the above technical solution, the second mounting part includes a first connecting plate and a second connecting plate. The second connecting plate extends along a second direction, and the first connecting plate extends along the first direction, which can improve the stability of the second mounting part itself.

[0019] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a testing device, including a support part, the support part being movably disposed on a second connecting plate along a second direction, a measuring part being disposed on the support part, and a probe being movably disposed sequentially through the support part and the second connecting plate along a first direction.

[0020] Using the above technical solution, the positions of the first reference plane and the second reference plane of different batches of standard gauge blocks (corresponding to different models of wheel speed sensors) may be different in the second direction. The bearing part is movably disposed on the second connecting plate along the second direction. Therefore, no matter where the first reference plane and the second reference plane are in the second direction, the probe can move to the corresponding position relative to the bearing part. The testing equipment can test standard gauge blocks of different batches and has better versatility.

[0021] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a detection device, wherein the second mounting part includes a first mounting through hole and a first through hole. Along a third direction, the first mounting through hole and the first through hole are spaced apart on the second connecting plate. Both the first mounting through hole and the first through hole extend along the second direction. The bearing part is movably disposed in the first mounting through hole along the second direction. Along the first direction, the probe is movably and sequentially inserted through the bearing part and the first through hole.

[0022] By adopting the above technical solution, the support part is movably disposed in the first mounting through hole along the second direction, and the probe is movably disposed in the support part and the first through hole in sequence along the first direction. In this way, the versatility of the testing equipment can be improved, and the weight of the second mounting part can be reduced, thus meeting the requirements of lightweight design.

[0023] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a testing device, wherein the second mounting part includes a second mounting through hole, and along the third direction, the first mounting through hole, the second mounting through hole and the first through hole are spaced apart in pairs on the second connecting plate, and the bearing part is movably disposed in the first mounting through hole and the second mounting through hole along the second direction.

[0024] By adopting the above technical solution, the support part is movably disposed in the first mounting through hole and the second mounting through hole along the second direction, which can further improve the connection stability between the support part and the second mounting part.

[0025] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a testing device, wherein the supporting part includes a first part and a second part, the first part extends along the second direction and is movably disposed in the first mounting through hole and the second mounting through hole along the second direction, the probe is movably disposed sequentially through the first part and the first through hole along the first direction, the second part extends away from the second mounting part along the first direction, and the measuring part includes a housing, the housing being disposed in the second part.

[0026] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a testing device, including a base, wherein a second connecting plate is movably disposed on the base along the first direction.

[0027] By adopting the above technical solution and setting a base, the overall stability of the testing equipment can be further improved. At the same time, the second connecting plate is movably set on the base along the first direction. When the measured gap is too large or too small, the size of the gap can be adjusted by adjusting the position of the second connecting plate on the base until the size of the gap meets the requirements.

They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0042] In existing technologies, the gap between the wheel speed sensor and the target wheel is mainly measured manually using a feeler gauge, which results in poor accuracy. Additionally, in some embodiments, a dial indicator is fixed to the wheel speed sensor, making the distance between them zero. During testing, the relative position of the product fixture and the target wheel is adjusted until the dial indicator reading reaches the desired gap value, at which point adjustment is stopped and the fixture is fixed. This approach has at least the following drawbacks: For example, for wheel speed sensors requiring gap calibration, the sensor's own gap value may already meet the requirements, necessitating only a check without adjustment. However, using the above method still requires readjusting the gap value, potentially leading to discrepancies in gap values ​​among sensors from the same batch.

[0043] Based on this, see Figure 1 , Figure 2 , Figure 3 In some embodiments, this application provides a detection device including a first mounting part 10, a standard gauge block 20, a second mounting part 30, and a measuring part 40. The measuring part 40 is used to measure the gap 502 between the standard gauge block 20 and the target wheel 50. The standard gauge block 20 is detachably mounted on the first mounting part 10 and includes a first reference surface 211 and a second reference surface 212 disposed opposite to each other along a first direction X, with a first distance L0 between the first reference surface 211 and the second reference surface 212. The second mounting part 30 is connected to the first mounting part 10. Along the first direction X, the first reference surface 211 is spaced apart from the second mounting part 30, and the second reference surface 212 is spaced apart from the side surface 501 of the target wheel 50 to form a gap 502. For example, the standard gauge block 20 includes a sensing head 21, with a first reference surface 211 and a second reference surface 212 disposed on both sides of the sensing head 21 in the first direction X. This application embodiment does not limit the type of sensing head 21. For example, in a magnetoelectric wheel speed sensor, the sensing head 21 is composed of a permanent magnet, a polar axis, an induction coil, etc.

[0044] In the production of wheel speed sensors, the standard gauge block 20 can be used to simulate the wheel speed sensor. After the standard gauge block 20 is tested and calibrated, the batch of wheel speed sensors can be mass-produced. In some embodiments, the standard gauge block 20 can also represent the wheel speed sensor to be tested. For example, when a wheel speed sensor in use malfunctions and needs to be tested, the testing equipment provided in this application embodiment can be used to test the performance of the wheel speed sensor. In this case, the standard gauge block 20 is the wheel speed sensor to be tested.

[0045] It is understood that the embodiments of this application do not limit the type of wheel speed sensor, such as a magnetoelectric wheel speed sensor, a Hall effect wheel speed sensor, etc.

[0046] In some embodiments, the measuring unit 40 is disposed on the second mounting portion 30. The measuring unit 40 is switchable between a first state and a second state. The measuring unit 40 includes a housing 41 and a probe 42. The probe 42 extends out of the housing 41 and is movably disposed on the second mounting portion 30 along a first direction X. In the first state (e.g.) Figure 3 As shown), the standard gauge block 20 is installed in the first mounting part 10, and the probe 42 abuts against the first reference surface 211 to obtain the first reference value L1. In the second state (as shown), the standard gauge block 20 is installed in the first mounting part 10, and the probe 42 abuts against the first reference surface 211 to obtain the first reference value L1. Figure 4 As shown, the standard gauge block 20 is not provided in the first mounting part 10, and the probe 42 is used to abut against the side 501 of the target wheel 50 to obtain the second reference value L2. Exemplarily, the measuring part 40 includes a dial indicator. It is understood that the type of measuring part 40 is not limited in this application embodiment, and it may also be a micrometer, etc.

[0047] Using the above technical solution, the first distance L0 between the first reference surface 211 and the second reference surface 212 of the standard measuring tool can be determined during manufacturing. The measuring part 40 is located on the second mounting part 30 and can switch between the first state and the second state. In the first state, the standard gauge block 20 is located on the first mounting part 10, and the probe 42 of the measuring part 40 abuts against the first reference surface 211. At this time, the measuring part obtains the first reference value L1, which is output on the screen of the dial indicator. In the second state, the standard gauge block 20 is not located on the first mounting part 10, and the probe 42 is used to abut against the side 501 of the target wheel 50. At this time, the measuring part obtains the second reference value L2, which is output on the screen of the dial indicator. Based on the measured data, the distance L3 from the first reference surface 211 to the side surface 501 of the target wheel 50 can be obtained by subtracting L0 from L2. This distance L3 includes the first gap L0. Therefore, the gap value from the second reference surface 212 to the side surface 501 of the target wheel 50 can be obtained by subtracting L0 from L3. There is no need to manually insert a feeler gauge into the gap 502 between the second reference surface 212 and the side surface 501 of the target wheel. Therefore, it is not affected by the insufficient accuracy of the feeler gauge itself or the operator's professional level. The operation is simple and has high measurement accuracy. Typically, the gap value of the wheel speed sensor for the front wheels of a vehicle should be 1.10mm to 1.97mm, and the gap value for the rear wheels should be 0.42mm to 0.80mm. The specific value is determined based on factors such as the type of sensor and the actual application scenario. This embodiment does not limit this.

[0048] Furthermore, for wheel speed sensors that require clearance value verification, the standard gauge block 20 is the wheel speed sensor to be tested. That is, the clearance value of the wheel speed sensor may meet the requirements. Through the above technical solution, the testing equipment provided in this application embodiment can verify whether the clearance value meets the requirements through simple operation, without having to readjust the clearance value, thus avoiding deviations in the clearance values ​​of sensors in the same batch.

[0049] Understandably, in the first state, the measuring unit 40 can also be zeroed at the first reference surface 211 to perform zero-point calibration and output a more accurate gap value. At this time, L1 = 0 and L2 = L3. In the second state, L2 is the distance L3 from the first reference surface 211 to the side surface 501 of the target wheel 50. By subtracting L0 from L2 (L3), the gap value from the second reference surface 212 to the side surface 501 of the target wheel 50 can be obtained.

[0050] In some embodiments, see Figure 1 , Figure 2 The testing equipment includes a base 60, and a second mounting part 30 is movably mounted on the base 60 along a first direction X. By setting the base 60, the overall stability of the testing equipment can be further improved. At the same time, since the second mounting part 30 is movably mounted on the base 60 along the first direction X, when the measured gap 502 is too large or too small, the size of the gap 502 can be adjusted by adjusting the position of the second mounting part 30 on the base 60 until the size of the gap 502 meets the requirements.

[0051] For example, see Figure 2 When the gap 502 is too small, the second mounting part 30 and the first mounting part 10 are moved together along direction Q. When the gap 502 is too large, the second mounting part 30 and the first mounting part 10 are moved together along direction E. For example, along the first direction X, the base 60 has at least three rows of first mounting holes 601 spaced apart, each row including at least one first mounting hole 601. The second mounting part 30 includes at least one second mounting hole 301. Along the second direction Y, the projection of the second mounting hole 301 coincides with that of any row of first mounting holes 601, allowing bolts or other connecting parts (not shown) to detachably connect the second mounting part 30 and the base 60. The three rows of first mounting holes 601 correspond to three different positions. By cooperating with the second mounting holes 301 in different rows of first mounting holes 601, the position of the second mounting part 30 on the base 60 can be adjusted, thereby adjusting the size of the gap 502.

[0052] Understandably, the embodiments of this application do not limit the number of the first mounting hole 601 and the second mounting hole 301. For example, the number of the first mounting hole 601 can be 3, 4, 5, 6, 7, 8, etc., and the number of the second mounting hole 301 can be 1, 2, 3, 4, 5, etc.

[0053] In some embodiments, see Figure 1 , Figure 2The first mounting portion 10 and the second mounting portion 30 are detachably connected, and the second mounting portion 30 and the base 60 are detachably connected, giving the testing device provided in this application embodiment the advantage of being easy to store and carry. Exemplarily, the first mounting portion 10, the second mounting portion 30, and the base 60 are all plate-shaped, and their projections in the third direction Z are "Z"-shaped, wherein the first mounting portion 10 and the base 60 are parallel, and the second mounting portion 30 is perpendicular to the first mounting portion 10 and the base 60. It is understood that this application embodiment does not limit the shape of the first mounting portion 10, the second mounting portion 30, and the base 60; for example, they can be columnar.

[0054] In some embodiments, the measuring unit 40 further includes a third state, which can switch between a first state, a second state, and a third state. In the third state, the probe 42 does not abut against the first reference surface 211 and the side surface 501 of the target wheel 50. In the third state, the probe 42 does not abut against the first reference surface 211 and the side surface 501 of the target wheel 50, that is, the measuring unit 40 is in a closed state, which can prevent damage to the probe 42 and extend the service life of the probe 42.

[0055] In some embodiments, see Figure 3 , Figure 4 , Figure 5 The first mounting portion 10 includes a mounting groove 101, which is located on the top surface 102 of the first mounting portion 10. The standard gauge block 20 includes a fixing portion 201 and a detection portion 202. A sensor head 21 is located at the end of the detection portion 202 away from the fixing portion 201 along the second direction Y. The fixing portion 201 is sleeved around the periphery of the detection portion 202. The detection portion 202 passes through the mounting groove 101, and the fixing portion 201 abuts against the bottom wall 1011 of the mounting groove 101. Along the second direction Y, a first reference surface 211 and a second reference surface 212 are located on the side of the detection portion 202 away from the fixing portion 201. Exemplarily, the mounting groove 101 includes a third mounting hole 1012, which is formed in the bottom wall 1011 of the mounting groove 101. The detection portion 202 extends through the third mounting hole 1012 along the second direction Y. For example, the shape of the mounting groove 101 is the same as the shape of the fixing part 201, and the fixing part 201 can be fitted to the side wall 1013 of the mounting groove 101. The embodiments of this application do not limit the shape of the mounting groove 101 and the fixing part 201, for example, they can also be elliptical, rectangular or other irregular shapes.

[0056] In some embodiments, see Figure 3 , Figure 4 , Figure 5 and combined Figure 1The first mounting portion 10 includes at least one fourth mounting hole 103. Along the first direction X, the fourth mounting hole 103 is located at the end where the first mounting portion 10 connects to the second mounting portion 30, and is used to achieve a detachable connection between the first mounting portion 10 and the second mounting portion 30 via bolts or other connecting components. It is understood that the number of fourth mounting holes 103 is not limited in this application embodiment; for example, it can be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, etc.

[0057] In some embodiments, see Figure 3 , Figure 4 , Figure 5 and combined Figure 1 The second mounting portion 30 includes a first connecting plate 31 and a second connecting plate 32. The first connecting plate 31 extends along a first direction X, and the second connecting plate 32 extends along a second direction Y. Along the first direction X, a first reference surface 211 is spaced apart from the second connecting plate 32. Along the second direction Y, one end of the second connecting plate 32 is connected to the first mounting portion 10, and the other end is connected to the first connecting plate 31. The probe 42 is movably mounted on the second connecting plate 32 along the first direction X. Exemplarily, the first mounting portion 10 and one end of the second connecting plate 32 are detachably connected through a fourth mounting hole 103. The first connecting plate 31 has two second mounting holes 301 for bolts or other connecting components to detachably connect the first connecting plate 31 and the base 60. Exemplarily, the first connecting plate 31 and the second connecting plate 32 are perpendicular, and their projections in the third direction Z form an "L" shape.

[0058] In some embodiments, see Figure 4 , Figure 5 , Figure 6 and combined Figure 1 The testing equipment also includes a support portion 70, which is movably disposed on the second connecting plate 32 along the second direction Y. A measuring portion 40 is disposed on the support portion 70, and a probe 42 is movably disposed sequentially through the support portion 70 and the second connecting plate 32 along the first direction X. Exemplarily, the support portion 70 includes a first part 71 and a second part 72. The first part 71 extends along the second direction Y, and the probe 42 is movably disposed sequentially through the first part 71 and the first through hole 322 along the first direction X. The second part 72 extends away from the second mounting portion 30 along the first direction X, and the housing 41 of the measuring portion 40 is disposed on the second part 72.

[0059] In some embodiments, see Figure 4 , Figure 5 , Figure 6 and combined Figure 1The second connecting plate 32 includes a first mounting through hole 321 and a first through hole 322. Along the third direction Z, the first mounting through hole 321 and the first through hole 322 are spaced apart on the second connecting plate 32. Both the first mounting through hole 321 and the first through hole 322 extend along the second direction Y. The supporting part 70 is movably disposed in the first mounting through hole 321 along the second direction Y. Along the first direction X, the probe 42 is movably disposed sequentially through the supporting part 70 and the first through hole 322. For example, the second mounting part 30 includes a second mounting through hole 323. Along the third direction Z, the first mounting through hole 321, the second mounting through hole 323, and the first through hole 322 are spaced apart in pairs on the second connecting plate 32. The first part 71 is movably disposed in the first mounting through hole 321 and the second mounting through hole 323 along the second direction Y.

[0060] For example, the first part 71 and the second part 72 are perpendicular, and their projection in the third direction Z is "L"-shaped. The first part 71 is parallel to the second connecting plate 32. The first part 71 includes a fifth mounting hole 711 and a sixth mounting hole 712. The fifth mounting hole 711 is correspondingly provided with the first mounting through hole 321, and the sixth mounting hole 712 is correspondingly provided with the second mounting through hole 323, so as to realize the detachable connection between the first part 71 and the second connecting plate 32. When it is necessary to change the position of the bearing part 70 on the second connecting plate 32, simply loosen the bolts and other connecting parts, so that the first part 71 moves upward or downward along the second direction Y to the desired position, and then tighten the bolts and other connecting parts.
