Description

A sensor centering device Technical Field

[0001] This utility model relates to the field of auxiliary installation technology, specifically to a sensor centering device. Background Technology

[0002] During the assembly of the steering shaft assembly, the sensors on the steering shaft assembly need to be centered to ensure that the sensors remain symmetrical within a certain error range during the rotation of the steering shaft.

[0003] In existing sensor centering equipment, the steering shaft assembly to be centered is placed in a positioning fixture, and the rotation of the sensor's elastic rotation limit is restricted. The lower part is clamped by a pneumatic chuck, and the upper part is driven by an inner spline sleeve that surrounds the outer spline of the input shaft. The input shaft is driven to twist left and right, and the torsional characteristics of the sensor's main and auxiliary signals are tested to optimize the upper and lower limits of the signals, torsion bar hysteresis, and stiffness coefficient.

[0004] However, during the testing of the above scheme, the positioning fixture can interfere with the test results. Summary of the Invention

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the problem of the positioning fixture interfering with the test results in the prior art, thereby providing a sensor centering device.

[0006] To address the aforementioned technical problems, this utility model provides a sensor alignment device, comprising: a cabinet, a positioning mechanism, an orientation mechanism, and a testing mechanism. The cabinet has a mounting platform on its top. The positioning mechanism is disposed on the mounting platform and includes a positioning clamp and a clamping member. The positioning clamp is vertically and movably disposed on the mounting platform and has a positioning groove formed on it for inserting a product to be aligned. The clamping member is movably disposed on the mounting platform and is used to position and clamp the output shaft of the product to be aligned. The orientation mechanism is disposed on the mounting platform and is used to restrict the rotation of the sensor of the product to be aligned. The testing mechanism is vertically and movably disposed on the mounting platform and is located above the positioning mechanism. The testing mechanism is provided with a rotation drive mechanism for driving the input end of the product to be aligned to rotate.

[0007] In use, the output end of the product to be calibrated is placed in the positioning groove of the positioning fixture. The orientation mechanism restricts the rotation of the sensor of the product to be calibrated. The clamping member clamps the input shaft of the product to be calibrated. The testing mechanism moves downward, and the rotation drive mechanism of the testing mechanism clamps and fixes the input shaft of the product to be calibrated. The clamping member is released and reset. The positioning fixture moves downward and disengages from the product to be calibrated. The rotation drive mechanism controls the input shaft of the product to be calibrated to rotate clockwise or counterclockwise. The testing mechanism detects the torsional characteristics of the main and auxiliary signals of the sensor of the product to be calibrated and optimizes the upper and lower limits of the signal, the torsion bar hysteresis and the stiffness coefficient. The sensor calibrating device provided by this utility model solves the problem that the positioning fixture in the prior art will interfere with the test results.

[0008] Optionally, the mounting platform is provided with a lifting hole, and the positioning fixture is movably mounted in the lifting hole via a first lifting mechanism. With this configuration, after the input shaft of the product to be adjusted is clamped and fixed by the rotation drive structure of the testing mechanism, the positioning fixture moves downward through the lifting hole on the mounting platform, disengaging the positioning fixture from the product to be adjusted and preventing the positioning fixture from affecting the test results.

[0009] Optionally, the first lifting mechanism includes: a guide member, a first lifting device, and a sliding plate; the guide member is disposed within the lifting hole, and its interior has a guide groove for sliding of the positioning fixture, the guide groove being coaxially arranged with the positioning fixture; the first lifting device is disposed on the mounting platform, and its drive end extends into the cabinet; the sliding plate is disposed at the drive end of the first lifting device, and the sliding plate is connected to the bottom of the positioning fixture. With the above arrangement, the first lifting device drives the sliding plate to move the positioning fixture up and down along the guide groove inside the guide member, and the guide member can limit and guide the up and down movement of the positioning fixture.

[0010] Optionally, the clamping members are two oppositely arranged, and a sliding mechanism is provided inside the cabinet. The first end of each clamping member is throttledly connected to the sliding mechanism. The mounting platform has a hole for the second end of each clamping member to extend out. The second end of each clamping member has an abutting surface for pressing against the product to be adjusted. The sliding mechanism drives the two clamping members to move closer or further apart. With this configuration, when the product to be adjusted needs to be fixed, the sliding mechanism drives the two oppositely arranged clamping members closer together; when the product to be adjusted needs to be released, the sliding mechanism drives the two oppositely arranged clamping members further apart.

[0011] Optionally, the testing mechanism is provided with a second lifting mechanism, which includes: a stand, a first slide rail, a first slider, and a second lifting device. The stand is disposed on the mounting platform; the first slide rail is vertically disposed on the stand; the first slider is slidably disposed on the first slide rail, and the testing mechanism is disposed on the side of the first slider away from the first slide rail; the second lifting device is disposed on the stand, and the drive end of the second lifting device is connected to the slider. With the above arrangement, the stand allows the testing mechanism to be positioned above the positioning mechanism, and the second lifting device drives the first slider to move the testing mechanism vertically along the first slide rail.

[0012] Optionally, a stop is provided at the bottom end of the first slide rail, and the stop engages with the first slider to prevent it from slipping off the first slide rail. This design prevents the first slider from slipping off the first slide rail.

[0013] Optionally, the rotary drive mechanism includes: a clamping plate structure and a rotary motor; the clamping plate structure is disposed at the first end of the testing mechanism, and is used to clamp the input shaft of the product to be adjusted; the rotary motor is disposed at the second end of the testing mechanism, and is fixedly connected to the first slider. The drive end of the rotary motor is connected to the clamping plate structure for transmission, and the rotary motor is used to drive the clamping plate structure to rotate the input shaft of the product to be adjusted. With the above configuration, the clamping plate structure can clamp the input shaft of the product to be adjusted, and the rotary motor drives the clamping plate structure to rotate the input shaft of the product to be adjusted clockwise or counterclockwise. The clamping plate structure can avoid the misalignment of the spline sleeve and the outer spline sleeve of the input shaft in the prior art.

[0014] Optionally, the testing mechanism further includes a torque limiter, an angle sensor, and a torque sensor, which are arranged sequentially from top to bottom on the drive shaft of the rotary motor. With this arrangement, the main function of the torque limiter is overload protection, preventing damage to the product under adjustment due to excessive rotation. By combining data from the angle sensor and the torque sensor, the torsional characteristics of the sensor's primary and secondary signals of the product under adjustment are detected, allowing for optimization of signal upper and lower limits, torsion bar hysteresis, and stiffness coefficient.

[0015] Optionally, the orientation mechanism includes: a support, a guide rail, and a slider; the support is disposed on the mounting platform; the guide rail is disposed on the top of the support; the slider is slidably disposed on the guide rail, and a limiting member is provided at one end of the slider near the positioning fixture, the limiting member being used to engage with the sensor of the product to be calibrated. With the above configuration, the support can ensure that the limiting member is at the same height as the sensor of the product to be calibrated. During testing, by pushing the slider, the limiting member moves towards the product to be calibrated, and the end of the limiting member engages with the sensor of the product to be calibrated, thereby restricting the rotation of the sensor. After the test, by pushing the slider, the limiting member moves away from the product to be calibrated, and the end of the limiting member separates from the sensor of the product to be calibrated.

[0016] Optionally, a straightening mechanism is provided on the mounting platform. The straightening mechanism includes a base plate, a straightening robot, and a lateral drive device. The base plate is mounted on the mounting platform; the straightening robot is slidably mounted on the base plate; the lateral drive device is mounted on the base plate, and its drive end is connected to the straightening robot. The lateral drive device drives the straightening robot to move closer to or away from the product to be adjusted. With this configuration, the straightening robot is slidably mounted on the mounting platform via the base plate. Before the testing mechanism descends, the lateral drive device drives the straightening robot to move towards the product to be adjusted, fixing the input shaft of the product and centering it. After the testing mechanism descends, the upper part of the input shaft of the product to be adjusted is placed in the clamping structure of the rotary drive mechanism, ensuring that the clamping structure holds and fixes the product to be adjusted. After the clamping structure has fixed the product to be adjusted, the straightening robot releases the product, and the lateral drive device drives the straightening robot to move away from the product to reset.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] This embodiment provides a structure for a sensor centering device that can improve the accuracy of test results, used to detect the torsional characteristics of the main and auxiliary signals of the sensor of the product to be centered (6).

[0032] As shown in Figures 1-7, this embodiment provides a specific implementation of a sensor alignment device, comprising: a cabinet 1, a positioning mechanism 2, an orientation mechanism 3, and a testing mechanism 4. The cabinet 1 has a mounting platform 11 on its top. The positioning mechanism 2 is disposed on the mounting platform 11 and includes a positioning clamp 21 and a clamping member 22. The positioning clamp 21 is movably disposed on the mounting platform 11 and has a positioning groove for inserting the product 6 to be aligned. The clamping member 22 is movably disposed on the mounting platform 11 and is used to position and clamp the output shaft of the product 6 to be aligned. The orientation mechanism 3 is disposed on the mounting platform 11 and is used to restrict the rotation of the sensor of the product 6 to be aligned. The testing mechanism 4 is movably disposed on the mounting platform 11 and is located above the positioning mechanism 2. The testing mechanism 4 is provided with a rotation drive mechanism, which is used to drive the input end of the product 6 to be aligned to rotate.

[0033] In use, the output end of the product to be calibrated 6 is placed in the positioning groove of the positioning fixture 21. The orientation mechanism 3 restricts the rotation of the sensor of the product to be calibrated 6. The clamping member 22 clamps the input shaft of the product to be calibrated 6. The testing mechanism 4 moves downward. The rotation drive mechanism of the testing mechanism 4 clamps and fixes the input shaft of the product to be calibrated 6. The clamping member 22 is released and reset. The positioning fixture 21 moves downward and disengages from the product to be calibrated 6. The rotation drive mechanism controls the input shaft of the product to be calibrated 6 to rotate clockwise or counterclockwise. The testing mechanism 4 detects the torsional characteristics of the main and auxiliary signals of the sensor of the product to be calibrated 6 and optimizes the upper and lower limits of the signal, the torsion bar hysteresis and the stiffness coefficient. The sensor calibrating device provided in this embodiment solves the problem that the positioning fixture 21 will interfere with the test results in the prior art.

[0034] It should be noted that the product to be adjusted 6 is a steering shaft assembly, which has an upper input shaft and a lower output shaft. The output end of the product to be adjusted 6 is placed in the positioning fixture 21.

[0035] As shown in Figures 2-4, in the sensor alignment device provided in this embodiment, the mounting platform 11 is provided with a lifting hole, and the positioning clamp 21 is movably and vertically mounted in the lifting hole via a first lifting mechanism 23. When the input shaft of the product 6 to be aligned is clamped and fixed by the rotary drive structure of the testing mechanism 4, the positioning clamp 21 moves downward through the lifting hole on the mounting platform 11, causing the positioning clamp 21 to disengage from the product 6 to be aligned, thus preventing the positioning clamp 21 from affecting the test results. Alternatively, as an alternative implementation, the lifting hole can be omitted, and a mounting platform for mounting the positioning clamp 21 is provided above the mounting platform 11. The interior of the mounting platform forms a sliding groove for the positioning clamp 21 to move vertically. The first lifting mechanism 23 is mounted on the mounting platform, and the positioning clamp 21 is driven to extend out of the sliding groove or sink into the sliding groove by the first lifting mechanism 23.

[0036] As shown in Figures 2-4, in the sensor centering device provided in this embodiment, the first lifting mechanism 23 includes: a guide member 231, a first lifting device 232, and a sliding plate 233. The guide member 231 is disposed within the lifting hole, and its interior has a guide groove for sliding of the positioning clamp 21. The guide groove is coaxially arranged with the positioning clamp 21. The first lifting device 232 is disposed on the mounting platform 11, and its driving end extends into the cabinet 1. The sliding plate 233 is disposed at the driving end of the first lifting device 232 and is connected to the bottom of the positioning clamp 21. The first lifting device 232 drives the sliding plate 233 to move the positioning clamp 21 up and down along the guide groove inside the guide member 231. The guide member 231 can limit and guide the up and down movement of the positioning clamp 21. Alternatively, as an alternative embodiment, the sliding plate 233 can be omitted, and the first lifting device 232 can be disposed inside the cabinet 1 below the positioning clamp 21.

[0037] Specifically, the guide member 231 has a groove on its side wall for the sliding insertion of the slider.

[0038] As shown in Figures 2-4, in the sensor alignment device provided in this embodiment, there are two clamping members 22 arranged opposite each other. A sliding mechanism 24 is provided inside the cabinet 1. The first end of each clamping member 22 is connected to the sliding mechanism 24. The mounting platform 11 has a hole for the second end of each clamping member 22 to extend out. The second end of each clamping member 22 has an abutting surface for pressing against the product 6 to be aligned. The sliding mechanism 24 drives the two clamping members 22 to move closer or further apart. When it is necessary to fix the product 6 to be aligned, the sliding mechanism 24 drives the two oppositely arranged clamping members 22 to move closer together; when it is necessary to release the product 6 to be aligned, the sliding mechanism 24 drives the two oppositely arranged clamping members 22 to move further apart. Alternatively, as an alternative implementation, three or more clamping members 22 can be provided according to design requirements.

[0039] Specifically, the contact surface at the second end of the clamping member 22 is configured as an arc-shaped surface.

[0040] Specifically, the sliding mechanism 24 includes: a base, on which a sliding groove is provided, the sliding groove extending along the radial direction of the positioning clamp 21, and the second end of the clamping member 22 being driven by a driving device to move along the sliding groove.

[0041] As shown in Figures 1 and 5, in the sensor centering device provided in this embodiment, the testing mechanism 4 is equipped with a second lifting mechanism 43. The second lifting mechanism 43 includes: a stand 431, a first slide rail 432, a first slider 433, and a second lifting device 434. The stand 431 is disposed on the mounting platform 11; the first slide rail 432 is vertically disposed on the stand 431; the first slider 433 is slidably disposed on the first slide rail 432, and the testing mechanism 4 is disposed on the side of the first slider 433 away from the first slide rail 432; the second lifting device 434 is disposed on the stand 431, and the driving end of the second lifting device 434 is connected to the slider. The stand 431 enables the testing mechanism 4 to be positioned above the positioning mechanism 2. The second lifting device 434 drives the first slider 433 to move the testing mechanism 4 vertically along the first slide rail 432. Specifically, the second lifting device 434 is configured as an electric push rod or a pneumatic push rod. Alternatively, as an alternative implementation, the first slider 433 can be omitted, the second lifting device 434 can be configured as an electric slider, and the testing device can be fixedly mounted on the electric slider.

[0042] As shown in Figure 5, in the sensor centering device provided in this embodiment, a stop is provided at the bottom end of the first slide rail 432, and the stop and the first slider 433 form a blocking engagement. The stop can prevent the first slider 433 from slipping off the first slide rail 432.

[0043] As shown in Figures 1 and 5, in the sensor alignment device provided in this embodiment, the rotary drive mechanism includes a clamping structure 41 and a rotary motor 42. The clamping structure 41 is disposed at the first end of the testing mechanism 4 and is used to clamp the input shaft of the product 6 to be aligned. The rotary motor 42 is disposed at the second end of the testing mechanism 4 and is fixedly connected to the first slider 433. The drive end of the rotary motor 42 is connected to the clamping structure 41, and the rotary motor 42 is used to drive the clamping structure 41 to rotate the input shaft of the product 6 to be aligned. The clamping structure 41 can clamp the input shaft of the product 6 to be aligned. By driving the clamping structure 41 driven by the rotary motor 42, the input shaft of the product 6 to be aligned can be rotated clockwise or counterclockwise. The clamping structure 41 can avoid the situation in the prior art where the spline sleeve and the outer spline sleeve of the input shaft are not properly aligned. Specifically, the clamping structure 41 is a pneumatic clamping plate. Alternatively, as an alternative implementation, the clamping structure 41 can also be replaced with a mechanical gripper.

[0044] As shown in Figures 1 and 5, in the sensor alignment device provided in this embodiment, the testing mechanism 4 further includes a torque limiter 46, an angle sensor 47, and a torque sensor 48, which are sequentially arranged from top to bottom on the drive shaft of the rotary motor 42. The main function of the torque limiter 46 is overload protection, which can prevent damage to the product 6 to be aligned due to excessive rotation. By combining the data from the angle sensor 47 and the torque sensor 48, the torsional characteristics of the sensor's main and auxiliary signals of the product 6 to be aligned are detected, and the upper and lower limits of the signals, the torsion bar hysteresis, and the stiffness coefficient are optimized.

[0045] Specifically, the drive end of the rotary motor 42 is also provided with a reducer 45, which is connected to the torque limiter 46 in a transmission manner.

[0046] As shown in Figures 1, 4, and 6, in the sensor centering device provided in this embodiment, the orientation mechanism 3 includes: a support 31, a guide rail 32, and a slider 33. The support 31 is disposed on the mounting platform 11; the guide rail 32 is disposed on the top of the support 31; the slider 33 is slidably disposed on the guide rail 32, and a limiting member is provided at one end of the slider 33 near the positioning clamp 21. The limiting member is used to engage with the sensor of the product to be centered. The support 31 enables the limiting member to be at the same height as the sensor of the product to be centered 6. During the test, by pushing the slider 33, the limiting member moves towards the product to be centered 6, and the end of the limiting member engages with the sensor of the product to be centered 6, thereby restricting the rotation of the sensor of the product to be centered 6. After the test, by pushing the slider 33, the limiting member moves away from the product to be centered 6, and the end of the limiting member separates from the sensor of the product to be centered 6. Alternatively, as an alternative implementation, the slider 33 can also be configured as an electric slider to automate the orientation mechanism 3.

[0047] Specifically, the slider 33 is provided with a handle 34 for gripping.

[0048] As shown in Figures 1 and 7, in the sensor centering device provided in this embodiment, a centering mechanism 5 is provided on the mounting platform 11. The centering mechanism 5 includes: a base plate 51, a centering robot 52, and a lateral drive device 53. The base plate 51 is disposed on the mounting platform 11; the centering robot 52 is slidably disposed on the base plate 51; the lateral drive device 53 is disposed on the base plate 51, and the drive end of the lateral drive device 53 is connected to the centering robot 52. The lateral drive device 53 drives the centering robot 52 to move closer to or away from the product 6 to be centered. The straightening robot 52 is slidably mounted on the mounting platform 11 via the base plate 51. Before the testing mechanism 4 descends, the lateral drive device 53 drives the straightening robot 52 to move towards the product to be adjusted 6. The straightening robot 52 fixes the input shaft of the product to be adjusted 6 and centers it. After the testing mechanism 4 descends, the upper part of the input shaft of the product to be adjusted 6 is placed in the clamping structure 41 of the rotary drive mechanism, ensuring that the clamping structure 41 clamps and fixes the product to be adjusted 6. After the clamping structure 41 clamps and fixes the product to be adjusted 6, the straightening robot 52 releases the product to be adjusted 6, and the lateral drive device 53 drives the straightening robot 52 to move away from the product to be adjusted 6 to reset. The operation of this straightening mechanism 5 is simple. Specifically, the lateral drive device 53 is set as an electric push rod or a pneumatic push rod. Alternatively, as an alternative implementation, the lateral drive device 53 can also be configured as an electric slider, and the straightening robot 52 can be mounted on the electric slider.

[0049] Specifically, a second slide rail 54 is provided on the base plate 51, and a second slider 55 is provided on the straightening robot 52. The second slider 55 is connected to the drive end of the lateral drive device 53. The lateral drive device pushes the second slider 55 to drive the straightening robot 52 to move along the second slide rail 54.

[0050] How to use:

[0051] As shown in Figure 1, in the sensor centering device provided in this embodiment, the output end of the product 6 to be centered is placed into the positioning groove of the positioning fixture 21, and the sliding member 33 of the orientation mechanism 3 is pushed so that the end of the sliding member 33 engages and restricts the rotation of the sensor of the product 6 to be centered. The sliding mechanism 24 drives the clamping member 22 to clamp the input shaft of the product 6 to be centered. The lateral driving device 53 of the straightening mechanism 5 drives the straightening robot 52 to approach the product 6 to be centered. The straightening robot 52 centers the product 6 to be centered. The testing machine... As the test mechanism 4 moves downward, the clamping structure 41 of the test mechanism 4 clamps and fixes the input shaft of the product 6 to be adjusted. The straightening manipulator 52 and the clamping member 22 release the product 6 to be adjusted and reset it. The positioning fixture 21 moves downward and disengages from the product 6 to be adjusted. The rotary motor 42 drives the clamping structure 41 to control the input shaft of the product 6 to be adjusted to rotate clockwise or counterclockwise. The torsional characteristics of the main and auxiliary signals of the sensor of the product 6 to be adjusted are detected by combining the data of the angle sensor 47 and the torque sensor 48, and the upper and lower limits of the signal, the torsion bar hysteresis and the stiffness coefficient are optimized.

[0052] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
