Description

Technical Field

[0001] This application relates to the field of automotive braking system technology, and in particular to a device for detecting the outer contour dimensions of a brake. Background Technology

[0002] As a key component of the automotive braking system, the performance of the brake directly affects the reliability and safety of the braking system. Improved braking performance is usually accompanied by an increase in the radial profile of the brake. However, in some low-end cars or passenger vans, small-sized wheels are used due to cost constraints. This makes the control of the outer profile size of the brake extremely important. Even a slight deviation may lead to interference between the outer profile of the brake and the wheel. Taking caliper disc brakes as an example, their outer contours are mostly cast blank surfaces with significant dimensional variations. Even slight changes in the theoretical clearance can cause interference problems in mass production, making the dimensional inspection of the outer contour particularly important. Various methods exist for inspecting the brake's outer contour, but each has its limitations. Traditional methods often use simple measuring tools such as vernier calipers and height gauges, manually measuring key dimensional points to infer the outer contour. This method is not only inefficient and requires highly skilled operators, but also highly subjective, easily leading to measurement errors due to human factors, and cannot meet the high-precision inspection requirements of large-scale production. Another method involves assembling the brake, including the caliper, disc, and steering knuckle, along with the wheels, according to the actual vehicle configuration, and checking for interference between parts by rotating the wheels. While this method can simulate actual usage to some extent, using all actual parts makes the assembly process extremely inconvenient, difficult to apply to automated production lines, and does not consider the manufacturing tolerances of the wheels themselves. Even brakes that pass inspection may still have interference risks in actual use. Utility Model Content

[0037] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The descriptions in this section are merely illustrative and explanatory, and should not be construed as limiting the scope of protection of this application. Specifically, the described embodiments are only some embodiments of this application, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort should fall within the scope of protection of this invention.

[0038] It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.

[0039] As mentioned in the background section, in order to solve the problems existing in the prior art, this embodiment provides a brake outer contour dimension detection device, including:

[0040] The frame 3 has a testing station, and the testing station is equipped with a brake 4 to be tested;

[0041] Positioning mechanism 1 is mounted on frame 3 and located above brake 4. Positioning mechanism 1 has a positioning end that can move vertically and abut against the central circular end face of brake 4 to position brake 4.

[0042] The detection mechanism 2 is mounted on the positioning mechanism 1. The detection mechanism 2 has a detection part 21, which is located on one side of the brake 4 and has a first gap with the brake 4. The detection part 21 can rotate around the central axis of the positioning end. The rotation trajectory of the detection part 21 near the brake 4 matches the circumferential outer contour of the standard-sized brake.

[0043] like Figure 1-4As shown, the brake 4 in this embodiment is a caliper disc brake in the prior art, including an integrally assembled brake caliper, brake disc, and steering knuckle. The center circle of the brake 4 is the half-shaft mounting hole of the steering knuckle and brake disc. The first horizontal direction is the width direction of the frame 3, i.e., the horizontal direction in the figure. The frame 3 is approximately a cuboid frame. The inspection station is located in the middle of the frame 3. The brake 4 is mounted on the accompanying fixture, and the central axis of its center circle extends vertically. The accompanying fixture can perform preliminary positioning of the brake 4 by cooperating with the outer contour of the bottom of the brake 4. The positioning mechanism 1 is located on the top of the frame 3 for positioning. The positioning end is located above the brake 4. The positioning end can move vertically downwards until it abuts against the central circular end face of the brake 4. It positions the brake 4 by pressing it against the brake 4 from both the top and bottom with the accompanying tooling, ensuring that the central axis of the brake 4's central circle is coaxial with the central axis of the positioning end. The detection mechanism 2 is mounted on the positioning mechanism 1 and can move vertically along with the positioning end. The detection part 21 is approximately a flat plate structure. When the positioning end abuts against the central circular end face of the brake 4, the detection part 21 is located on one side of the brake 4 in the horizontal direction. The end face contour of the detection part 21 near the brake 4 is aligned with the brake... There is a first gap between the circumferential outer contours of brake 4. The size of the first gap is equal to the allowable error of the circumferential outer contour dimension of brake 4. When the detection unit 21 rotates around the central axis of the positioning end, the motion trajectory formed by its end face near brake 4 matches the standard-sized circumferential outer contour of brake 4. If the dimension of the circumferential outer contour of brake 4 to be tested deviates from the standard dimension, brake 4 will contact or interfere with the rotating detection unit 21. Then, the inspector can judge whether the circumferential outer contour dimension of brake 4 meets the standard by whether there is contact or motion interference. Furthermore, it is possible to determine whether there is contact or motion interference between the brake 4 and the detection unit 21 in various ways. For example, a vibration sensor can be installed on the detection unit 21. When the detection unit 21 and the brake 4 make contact or make motion interference, the vibration sensor can receive a high-frequency vibration signal. Alternatively, the current or output torque of the drive device of the detection unit 21 can be monitored. When the detection unit 21 and the brake 4 make contact or make motion interference, the current of the drive device of the detection unit 21 increases or the output torque changes due to the increased load. A combination of various methods can also be used to detect the contact or motion interference between the brake 4 and the detection unit 21.

[0044] By setting a positioning mechanism 1 to position the brake 4 to be inspected, the brake 4 is coaxially set with the positioning end. At the same time, by setting a detection part 21, the movement trajectory of the end of the detection part 21 near the brake 4 when it rotates matches the outer contour of the standard-sized brake 4. Thus, the outer contour dimension of the brake 4 can be judged as qualified based on whether there is contact or movement interference between the detection part 21 and the brake 4 during the rotation process. Compared with the traditional detection method, the detection device can save manpower, avoid measurement errors caused by human factors, improve detection efficiency, unify measurement standards, and better adapt to automated production lines.

[0045] In a preferred embodiment, the positioning mechanism 1 includes:

[0046] Slide rail 11, two sets of slide rail 11 are respectively provided on both sides of the frame 3 along the first horizontal direction and extend along the vertical direction;

[0047] The positioning component is slidably connected to two sets of slide rails 11 at both ends along the first horizontal direction, and the bottom of the positioning component has a positioning end;

[0048] The second driving component 12 is mounted on the frame 3, and the driving end of the second driving component 12 extends vertically and is fixed to the positioning component.

[0049] Furthermore, the positioning component includes:

[0050] The connecting plate 14 has sliders 13 fixed at both ends along the first horizontal direction, and the two sets of sliders 13 are respectively embedded in the corresponding slide rails 11.

[0051] Positioning post 15 is located below connecting plate 14. Positioning post 15 extends vertically and has a guide head 16 at its free end.

[0052] For details, please refer to Figure 1 and Figure 3The slide rails 11 are provided in two sets, with two slide rails 11 in each set. The two sets of slide rails 11 are fixed on both sides of the top of the frame 3 along the first horizontal direction. The slide rails 11 extend vertically, and each slide rail 11 is embedded with a slider 13. The connecting plate 14 is approximately a cuboid plate structure, and four sliders 13 are fixed at the four corners of the top surface of the connecting plate 14 to ensure that the connecting plate 14 can slide stably along the slide rails 11. The second driving component 12 is a hydraulic cylinder from the prior art. The second driving component 12 is fixed on the top of the frame 3, located above the connecting plate 14. The piston rod of the driving component 12 is fixed to the top surface of the connecting plate 14, which can drive the connecting plate 14 to move in the vertical direction. The positioning post 15 is approximately cylindrical in structure. The positioning post 15 is fixed at the center of the bottom surface of the connecting plate 14 and extends in the vertical direction. The bottom of the positioning post 15 is provided with a guide head 16. The guide head 16 is coaxially arranged with the positioning post 15. The bottom of the guide head 16 has a tapered end face. The guide head 16 can abut against the central circular end face of the brake 4 to position the brake 4, so that the central axis of the central circle of the brake 4 is coaxial with the central axis of the positioning post 15.

[0053] In a preferred embodiment, the detection mechanism 2 includes:

[0054] The first driving member 22 is mounted on the positioning mechanism 1, and a driving gear 23 is sleeved on the driving shaft of the first driving member 22.

[0055] Gear ring 24 is rotatably connected to positioning mechanism 1, and its rotation axis is coaxial with the central axis of the positioning end. Gear ring 24 meshes with drive gear 23.

[0056] The connector 25 is fixed to the gear ring 24, and the free end of the connector 25 is provided with a detection part 21.

[0057] like Figure 2 and Figure 4 As shown, the first driving component 22 is a geared motor from the prior art. The first driving component 22 is fixed on the connecting plate 14 and located on one side of the positioning post 15 in the horizontal direction. The driving shaft of the first driving component 22 extends in the vertical direction. The driving gear 23 is fixed on the driving shaft of the first driving component 22. The gear ring 24 is sleeved on the positioning post 15 and rotatably connected to the positioning post 15. A connecting component 25 is fixed below the gear ring 24. The connecting component 25 is approximately a ring structure and is also sleeved on the positioning post 15. One end of the connecting component 25 extends in the horizontal direction and is fixed with a detection part 21. The first driving component 22 drives the gear ring 24 to rotate through the driving gear 23, thereby driving the connecting component 25 and the detection part 21 to rotate together around the central axis of the positioning post 15.

[0058] In a preferred embodiment, the detection mechanism 2 includes a conductive structure disposed on the positioning mechanism 1, and the conductive structure is electrically connected to the positioning mechanism 1 and the detection unit 21 respectively.

[0059] Furthermore, the conductive structure includes:

[0060] Circular guide rail 26 is mounted on positioning mechanism 1 and is coaxial with positioning end;

[0061] The conductive rod 27 is disposed on the detection part 21. The conductive rod 27 extends vertically and its free end abuts against the annular guide rail 26.

[0062] For details, please refer to Figure 4 Both the annular guide rail 26 and the conductive rod 27 are made of conductive material. The annular guide rail 26 is fixed to the bottom of the connecting plate 14 and is coaxially arranged with the positioning post 15. The conductive rod 27 is fixed on the detection part 21. The conductive rod 27 extends vertically and its top end can slide in contact with the annular guide rail 26. When the detection part 21 rotates around the positioning post 15, the conductive rod 27 always remains in contact with the annular guide rail 26. When there is contact or motion interference between the detection part 21 and the brake 4, a current loop is formed between the detection part 21, the conductive rod 27, the annular guide rail 26, the positioning component and the brake 4. The conductive structure can also be electrically connected to the PLC controller. The PLC controller detects whether a current loop is formed between the above structures to determine whether there is contact or motion interference between the brake 4 and the detection part 21, thereby realizing accurate detection of the circumferential outer contour dimension of the brake 4.

[0063] Furthermore, the positioning mechanism 1 is equipped with a detection element, which is used to detect the time required for the detection unit 21 to rotate one revolution around the central axis of the positioning end.

[0064] Specifically, the detection component can be a point sensor from the prior art. The bottom of the connecting plate 14 is provided with a mounting plate, and the detection component is fixed on the mounting plate. It can detect the time required for the detection part 21 to rotate one revolution around the central axis of the positioning column 15. The detection component is electrically connected to the PLC controller, and the two work together to monitor the rotation time of the detection part 21 during the detection process. The time for the detection part 21 to rotate one revolution during the detection process is compared with its standard rotation time, so as to determine whether there is contact or motion interference between the brake 4 and the detection part 21. By setting the detection component to monitor the rotation time of the detection part 21, it can ensure that the detection device can still achieve accurate detection of the circumferential outer contour dimension of the brake 4 when there is a fault in the conductive structure or when the detection part 21 is in contact with the non-metallic part of the brake 4.

[0065] In a preferred embodiment, a conveyor belt is also included, which runs through the frame 3 along a first horizontal direction. A conveyor platform 31 is provided on the conveyor belt, which is used to carry the brake 4. The conveyor belt is used to transport the brake 4 through the conveyor platform 31.

[0066] Furthermore, the frame 3 is also equipped with a lifting mechanism, which includes:

[0067] The third driving member 32 is mounted on the frame 3, and the driving end of the third driving member 32 extends in the vertical direction.

[0068] The lifting platform 33 is located on the drive end of the third drive member 32. The lifting platform 33 can drive the conveying platform 31 to move in the vertical direction under the drive of the third drive member 32.

[0069] For details, please refer to Figure 2 Two conveyor belts are provided, both extending along a first horizontal direction and passing through the frame 3. The two conveyor belts are arranged along a second horizontal direction, perpendicular to the first horizontal direction (i.e., perpendicular to the plane of the paper in the diagram). A second gap exists between the two conveyor belts. The conveying platform 31 is approximately a cuboid plate structure, with its two ends along the second horizontal direction mounted on the two conveyor belts respectively. It can move along the first horizontal direction with the conveyor belts, transporting the inspected brakes 4 to the next process and transporting the brakes 4 to be inspected to the frame 3. The third drive unit 32 also uses a hydraulic cylinder, similar to those in the prior art. The third drive unit 32 is located below the conveyor belt, and its piston rod extends vertically and is fixed to a lifting platform 33. The lifting platform 33 is also approximately a cuboid plate structure, lifting... The length of platform 33 along the second horizontal direction is less than the second gap. When the brake 4 to be tested moves along the first horizontal direction to above the lifting platform 33 under the conveyor belt conveyor 31, the conveyor belt stops, and the third drive member 32 drives the lifting platform 33 to move upward in the vertical direction. The lifting platform 33 passes through the second gap and abuts against the bottom of the conveyor platform 31, driving the conveyor platform 31 and the brake 4 to be tested to move together to the testing station for testing. After the testing is completed, the third drive member 32 drives the lifting platform 33 to move downward in the vertical direction. When the lifting platform 33 passes through the second gap again, the conveyor platform 31 and the lifting platform 33 separate. The conveyor platform 31 is placed on the conveyor belt, the conveyor belt is started, and the conveyor platform 31 and the tested brake 4 move along the first horizontal direction with the conveyor belt.

[0070] Furthermore, the conveying platform 31 is provided with a limiting structure 36, which is used to fix the brake 4 to be tested.

[0071] Specifically, the limiting structure 36 is the aforementioned accompanying tooling. The accompanying tooling can fix the brake 4 to be tested on the conveying platform 31 and perform preliminary positioning of the brake 4, so that the brake 4 can move with the conveying platform 31.

[0072] Furthermore, the frame 3 is provided with support mechanisms on both sides along the first horizontal direction. The support mechanism includes a fourth drive member 34. The drive end of the fourth drive member 34 is provided with a support part 35. The support part 35 can move along the first horizontal direction under the drive of the fourth drive member 34 and abut against the side of the conveying platform 31 near the lifting platform 33.

[0073] Specifically, the fourth drive component 34 also uses a hydraulic cylinder from the prior art. There are two fourth drive components 34, which are respectively located on both sides of the frame 3 along the first horizontal direction and correspond to the second gap in the vertical direction. The piston rods of the two fourth drive components 34 are located on the side that is close to each other. The support part 35 is a cuboid plate structure and is fixed on the piston rod of the fourth drive component 34. When the lifting platform 33 moves the conveying platform 31 and the brake 4 to be tested together to the testing station, the two fourth drive components 34 can drive the support parts 35 to move closer to each other along the first horizontal direction, so that the two support parts 35 abut against the bottom of the conveying platform 31 at both ends along the first horizontal direction, supporting the conveying platform 31 and extending the service life of the third drive component 32.

[0074] Working principle: First, the brake 4 to be tested is placed on the conveyor platform 31 and fixed by the accompanying fixture. The conveyor belt is started, and it drives the conveyor platform 31 and the brake 4 to be tested to move along the first horizontal direction. When the conveyor platform 31 moves above the lifting platform 33, the conveyor belt stops. The third drive unit 32 drives the lifting platform 33 to move vertically upward. The lifting platform 33 passes through the second gap and abuts against the bottom of the conveyor platform 31, moving the conveyor platform 31 and the brake 4 to be tested together to the testing station. Then, the fourth drive unit 34 is started. The two fourth drive units 34 drive the support parts 35 to move closer to each other along the first horizontal direction, so that the two support parts 35... The two ends of the guide head 16 are respectively positioned against the bottom of the conveyor platform 31 along the first horizontal direction to support the conveyor platform 31. The second drive unit 12 is activated, which drives the positioning column 15 to move downward in the vertical direction until the guide head 16 abuts against the end face of the center circle of the brake 4 to position the brake 4. After positioning, the first drive unit 22 is activated, which drives the gear ring 24 to rotate through the drive gear 23, causing the detection unit 21 to rotate around the brake 4. At the same time, the PLC controller determines whether there is contact or motion interference between the brake 4 and the detection unit 21 based on whether there is a current loop between the detection mechanism 2 and the brake 4, and then determines whether the circumferential outer contour dimension of the brake 4 meets the standard. Compared with traditional detection methods, the detection device can save manpower, avoid measurement errors caused by human factors, improve detection efficiency, unify measurement standards, and better adapt to automated production lines.
