Description

Technical Field

[0001] This invention relates to the field of automotive production and testing technology, and in particular to a method for pressing a brake pedal retainer ring. Background Technology

[0002] During the assembly of a car brake pedal, the assembly quality of the retaining ring and the central pivot directly affects the performance of the brake pedal.

[0003] Currently, existing assembly methods typically only complete the initial pressing of the retaining ring, failing to effectively identify whether the dimensions of the center pivot and the retaining ring are up to standard, and also making it difficult to accurately determine whether the retaining ring is properly pressed in. This results in some brake pedals making abnormal noises during actual use due to mismatched component dimensions or improper pressing, seriously affecting the driver's driving experience and potentially posing safety hazards.

[0004] Therefore, there is an urgent need for a method that can simultaneously detect dimensional conformity and pressing position during the pressing process of the retaining ring, in order to overcome the shortcomings of the existing technology. Summary of the Invention

[0005] The purpose of this invention is to provide a method for pressing a brake pedal retainer ring, which aims to solve the technical problems in the prior art of not being able to effectively identify whether the dimensions of the central pivot and the retainer ring are qualified, and also making it difficult to accurately determine whether the retainer ring is pressed in place.

[0006] To achieve the above objectives, the present invention provides a method for press-fitting a brake pedal retainer ring, comprising the following steps: Based on the design dimensions of the retaining ring and the central pivot, preset the minimum threshold Fmin, the maximum threshold Fmax, and the standard displacement value S for pressing into place; Place the retaining ring and the center shaft in the designated assembly position and align them with the reference. Start the servo electric cylinder to move the power sensor and the retaining ring toward the center shaft to begin press fitting. When the retaining ring contacts and is pressed into place with the central rotating shaft, the sensor acquires the pressing force value F1 and the displacement value S1. Based on the pressing force value F1, the minimum threshold Fmin, and the maximum threshold Fmax, the sensor determines whether the dimensions are qualified and outputs the initial pressing detection data. After the circlip pressing action is completed, the pressing force value F2 and displacement value S2 are obtained by the sensor. Based on the displacement value S2 and the standard displacement value S, it is determined whether the pressing is qualified and whether the servo electric cylinder has been reset, and the pressing in place detection data is output.

[0007] Among them, in the step of presetting the minimum threshold Fmin, the maximum threshold Fmax, and the standard displacement value S for pressing in place based on the design dimensions of the retaining ring and the central rotating shaft: Obtain the design dimension parameters of the retaining ring and the central rotating shaft, and set the minimum pressing force threshold Fmin based on the matching of the upper range of the retaining ring diameter and the lower range of the central rotating shaft diameter; Based on the matching of the lower range of the retaining ring diameter and the upper range of the central rotating shaft diameter, the maximum threshold value of the pressing force Fmax is set. Based on the assembly technical requirements of the brake pedal, the standard displacement value S for pressing the retaining ring into place is set.

[0008] In the steps of placing the retaining ring and the central rotating shaft in the designated assembly position and aligning them with the reference, and then starting the servo electric cylinder to move the power sensor and the retaining ring towards the central rotating shaft to begin the press-fitting process: Place the retaining ring to be assembled smoothly in the corresponding area of ​​the assembly station, install the center shaft, align the center shaft with the assembly reference of the retaining ring, start the servo electric cylinder to drive the matching force sensor and retaining ring to move synchronously towards the center shaft, and officially start the press-fitting process.

[0009] In the step of pressing the retaining ring into contact with the central rotating shaft, the sensor acquires the pressing force value F1 and the displacement value S1, and determines whether the dimensions are qualified based on the pressing force value F1, the minimum threshold Fmin, and the maximum threshold Fmax, and outputs the initial pressing test data: When the retaining ring begins to contact the central rotating shaft and is gradually pressed in, the force sensor captures the pressing force data in real time and records it as the pressing force value F1. The displacement sensor simultaneously records the displacement data corresponding to this contact pressing stage and records it as the displacement value S1. The obtained pressing force value F1 is compared with the preset minimum pressing force threshold Fmin and maximum pressing force threshold Fmax. Based on the comparison results, determine whether the dimensions of the retaining ring and the central rotating shaft match and output the complete test data for this stage, namely the initial test data for press-fitting.

[0010] In the step of determining whether the dimensions of the retaining ring and the central rotating shaft match according to the comparison results and outputting the complete inspection data for this stage, i.e., the initial inspection data of press-fitting, the process of determining whether the dimensions of the retaining ring and the central rotating shaft match according to the comparison results is as follows: If either the pressing force F1 is less than the minimum threshold Fmin or the pressing force F1 is greater than the maximum threshold Fmax, it is determined that the size of the retaining ring and the central rotating shaft do not match, and the component is unqualified.

[0011] In the step of determining whether the dimensions of the retaining ring and the central rotating shaft match according to the comparison results and outputting the complete inspection data for this stage, i.e., the initial inspection data of press-fitting, the process of determining whether the dimensions of the retaining ring and the central rotating shaft match according to the comparison results is as follows: If the pressing force F1 is between the minimum threshold Fmin and the maximum threshold Fmax, then the component size is deemed to be qualified.

[0012] In the process of completing the circlip pressing action, the pressing force value F2 and displacement value S2 are acquired by the sensor, and the pressing is judged as qualified and the servo electric cylinder is reset based on the displacement value S2 and the standard displacement value S, and the pressing in place detection data is output: Once the pressing action of the retaining ring is completed, the force sensor collects the final pressing force data and records it as the pressing force value F2, and the displacement sensor simultaneously acquires the actual displacement data of the pressing completed state and records it as the displacement value S2. Compare the displacement value S2 with the standard displacement value S; Based on the comparison results, determine whether the retaining ring is properly pressed in, and output the complete test data for this stage, namely the press-in test data.

[0013] In the step of determining whether the retaining ring is properly pressed in based on the comparison results and outputting the complete test data for this stage, i.e., the press-in test data, the process of determining whether the retaining ring is properly pressed in based on the comparison results is as follows: If the displacement value S2 is less than the standard displacement value S, it is determined that the retaining ring is not properly pressed in.

[0014] In the step of determining whether the retaining ring is properly pressed in based on the comparison results and outputting the complete test data for this stage, i.e., the press-in test data, the process of determining whether the retaining ring is properly pressed in based on the comparison results is as follows: If the displacement value S2 is greater than or equal to the standard displacement value S, then the circlip pressing is deemed qualified.

[0015] This invention discloses a method for pressing a brake pedal retainer ring. Based on the design dimensions of the retainer ring and the central pivot, a minimum pressing force threshold Fmin, a maximum threshold Fmax, and a standard pressing displacement value S are preset. The retainer ring and the central pivot are placed in a designated assembly position and aligned with a reference. A servo electric cylinder drives a power sensor to move the retainer ring towards the central pivot, initiating the pressing process. When the retainer ring contacts and is pressed into place with the central pivot, the sensor acquires the pressing force value F1 and the displacement value S1. The sensor determines whether the dimensions are acceptable based on the pressing force value F1, the minimum threshold Fmin, and the maximum threshold Fmax, and outputs initial pressing detection data. After the retainer ring pressing action is completed, the sensor acquires the pressing force value F2 and the displacement value S2. The sensor determines whether the pressing is acceptable and whether the servo electric cylinder has reset based on the displacement value S2 and the standard displacement value S, and outputs pressing completion detection data. Through this method, the dimensional compliance and pressing completion status can be simultaneously detected during the retainer ring pressing process, thereby ensuring the structural stability of the brake pedal and improving the driver's driving experience and driving safety.

[0028] Please see Figures 1-5 The present invention provides a method for press-fitting a brake pedal retainer ring, comprising the following steps: S100: Based on the design dimensions of the retaining ring and the central rotating shaft, preset the minimum threshold Fmin, the maximum threshold Fmax, and the standard displacement value S for pressing into place.

[0029] In this embodiment, based on the design dimensions of the retaining ring and the central rotating shaft, a minimum pressing force threshold Fmin, a maximum pressing force threshold Fmax, and a standard pressing displacement value S are preset. The specific process is as follows: S101: Obtain the design dimension parameters of the retaining ring and the central rotating shaft, and set the minimum pressing force threshold Fmin based on the matching of the upper range of the retaining ring diameter and the lower range of the central rotating shaft diameter; S102: Based on the matching of the lower limit of the retaining ring diameter and the upper limit of the central shaft diameter, set the maximum threshold of the pressing force Fmax; S103: Based on the assembly technical requirements of the brake pedal, set the standard displacement value S for pressing the retaining ring into place.

[0030] In the above process, the design dimensional parameters of the retaining ring and the central pivot shaft were first comprehensively collected, covering core data such as the diameter tolerance range of the retaining ring and the diameter tolerance range of the central pivot shaft. Based on this, the matching scenario was analyzed in detail when the retaining ring diameter was at the upper limit (i.e., the retaining ring diameter reached the maximum allowable design size) and the central pivot shaft diameter was at the lower limit (i.e., the central pivot shaft diameter reached the minimum allowable design size). Since the fit clearance between the retaining ring and the central pivot shaft is largest in this scenario, and the required pressing force is smallest, the minimum pressing force threshold Fmin was precisely set based on the mechanical characteristics and assembly process requirements of this scenario.

[0031] This study focuses on the matching situation where the retaining ring diameter is at the lower limit (i.e., the retaining ring diameter reaches the minimum design allowable size) and the center shaft diameter is at the upper limit (i.e., the center shaft diameter reaches the maximum design allowable size). In this scenario, the clearance between the retaining ring and the center shaft is minimal, the resistance to overcome during press-fitting is greatest, and the corresponding press-fitting force is also maximum. Based on the structural adaptability and mechanical analysis results of this scenario, a reasonable maximum press-fitting force threshold Fmax is set to ensure that the dimensional compliance of the component can be determined by whether the press-fitting force is between Fmin and Fmax.

[0032] Based on the overall assembly specifications of the brake pedal, the assembly depth requirements of the retaining ring and the central pivot, and the structural stability requirements during subsequent use, the standard displacement value S that the retaining ring should achieve when pressed into place is comprehensively determined. This value must ensure that the retaining ring can form a stable fit with the central pivot after pressing, meeting the normal working performance of the brake pedal, and providing a clear quantitative basis for subsequent judgment on whether the pressing is in place.

[0033] S200: Place the retaining ring and the center shaft in the designated assembly position and align them with the reference. Start the servo electric cylinder to move the power sensor and retaining ring toward the center shaft to begin press fitting.

[0034] In this embodiment, the retaining ring and the central rotating shaft are placed in the designated assembly position and aligned with the reference. The servo electric cylinder is then activated to move the power sensor and the retaining ring towards the central rotating shaft, initiating the press-fitting process. The specific process is as follows: Place the retaining ring to be assembled smoothly in the corresponding area of ​​the assembly station, install the center shaft, align the center shaft with the assembly reference of the retaining ring, start the servo electric cylinder to drive the matching force sensor and retaining ring to move synchronously towards the center shaft, and officially start the press-fitting process.

[0035] In the above process, firstly, the operator places the retaining ring to be assembled steadily in the designated area of ​​the assembly station, ensuring that the retaining ring is placed upright without tilting or offset, to avoid affecting the subsequent pressing accuracy due to initial position deviation. Then, the central rotating shaft is precisely installed onto the corresponding mounting base at the assembly station. Using auxiliary structures such as locating pins and reference surfaces at the station, the relative position of the central rotating shaft and the retaining ring is carefully adjusted to ensure that their assembly references are completely aligned, guaranteeing that the retaining ring can be accurately pressed into the central rotating shaft along the preset direction during the pressing process. After the parts are placed and aligned with the references, the servo electric cylinder is activated. The servo electric cylinder outputs a stable and controllable driving force according to preset drive parameters, simultaneously driving the matching force sensor and the retaining ring to move synchronously in a uniform linear motion towards the central rotating shaft, officially starting the retaining ring pressing process.

[0036] S300: When the retaining ring contacts and is pressed into place, the sensor acquires the pressing force value F1 and the displacement value S1. Based on the pressing force value F1, the minimum threshold Fmin, and the maximum threshold Fmax, the sensor determines whether the dimensions are qualified and outputs the initial pressing detection data.

[0037] In this embodiment, when the retaining ring contacts and is pressed into place with the central rotating shaft, the pressing force value F1 and displacement value S1 are acquired by a sensor. Based on the pressing force value F1, the minimum threshold Fmin, and the maximum threshold Fmax, the dimensional accuracy is determined, and initial pressing detection data is output. The specific process is as follows: S301: When the retaining ring begins to contact the central rotating shaft and is gradually pressed in, the force sensor captures the pressing force data at this time in real time and records it as the pressing force value F1. The displacement sensor synchronously records the displacement data corresponding to this contact pressing stage and records it as the displacement value S1. S302: Compare the obtained pressing force value F1 with the preset minimum pressing force threshold Fmin and maximum pressing force threshold Fmax; S303: Based on the comparison results, determine whether the dimensions of the retaining ring and the central rotating shaft match and output the complete test data for this stage, i.e., the initial test data for press-fitting.

[0038] In the step of determining whether the dimensions of the retaining ring and the central rotating shaft match according to the comparison results, and outputting the complete inspection data for this stage, i.e., the initial inspection data of press-fitting, the process of determining whether the dimensions of the retaining ring and the central rotating shaft match according to the comparison results is as follows: If either the pressing force F1 is less than the minimum threshold Fmin or the pressing force F1 is greater than the maximum threshold Fmax, it is determined that the size of the retaining ring and the central rotating shaft do not match, and the component is unqualified. If the pressing force F1 is between the minimum threshold Fmin and the maximum threshold Fmax, then the component size is deemed to be qualified.

[0039] During the above process, as the servo electric cylinder drives the retaining ring to move towards the central rotating shaft, when the retaining ring begins to contact the central rotating shaft and gradually presses in, the force sensor immediately enters real-time working state, accurately capturing the pressing force data at this time and recording this data as the pressing force value F1; at the same time, the displacement sensor synchronously starts data recording, accurately collecting the displacement data corresponding to the retaining ring during the contact pressing stage, and recording it as the displacement value S1, ensuring that the acquisition time of the pressing force and displacement data is completely synchronized, providing accurate data support for subsequent judgment.

[0040] The pressing force value F1 collected by the force sensor is compared one by one with the minimum pressing force threshold Fmin and the maximum pressing force threshold Fmax set in the parameter preset stage to clarify the numerical relationship between F1 and the two thresholds.

[0041] Based on the comparison results, the dimensional conformity of the retaining ring and the central rotating shaft is determined: if the pressing force F1 is less than the preset minimum threshold Fmin, it indicates that the fit clearance between the retaining ring and the central rotating shaft is too large, and the two dimensions do not match; if the pressing force F1 is greater than the preset maximum threshold Fmax, it indicates that the fit between the retaining ring and the central rotating shaft is too tight, which also constitutes a dimensional mismatch. Both of these situations are considered as component non-conforming; if the pressing force F1 is between the minimum threshold Fmin and the maximum threshold Fmax, it indicates that the dimensional conformity between the retaining ring and the central rotating shaft meets the assembly requirements, and the component dimensions are deemed conforming. After completing the conformity determination, the complete inspection data for this stage is output, including the pressing force F1, the displacement value S1, and the conformity determination result, i.e., the initial pressing inspection data, providing a decision-making basis for the subsequent process.

[0042] S400: After the circlip pressing action is completed, the pressing force value F2 and displacement value S2 are obtained through the sensor. Based on the displacement value S2 and the standard displacement value S, it is determined whether the pressing is qualified and whether the servo electric cylinder has been reset, and the pressing in place detection data is output.

[0043] In this embodiment, after the circlip pressing action is completed, the pressing force value F2 and displacement value S2 are acquired by a sensor. Based on the displacement value S2 and the standard displacement value S, it is determined whether the pressing is qualified and whether the servo electric cylinder has reset, and the pressing in place detection data is output. The specific process is as follows: S401: When the pressing action of the retaining ring is completed, the force sensor collects the final pressing force data and records it as the pressing force value F2, and the displacement sensor simultaneously acquires the actual displacement data of the pressing completed state and records it as the displacement value S2. S402: Compare the displacement value S2 with the standard displacement value S; S403: Determine whether the retaining ring is properly pressed in based on the comparison results, and output the complete test data for this stage, i.e., the test data for proper pressing in.

[0044] In the step of determining whether the retaining ring is properly press-fitted based on the comparison results and outputting the complete test data for this stage, i.e., the press-fitting test data, the process of determining whether the retaining ring is properly press-fitted based on the comparison results is as follows: If the displacement value S2 is less than the standard displacement value S, it is determined that the retaining ring is not properly pressed in. If the displacement value S2 is greater than or equal to the standard displacement value S, then the circlip pressing is deemed qualified.

[0045] During the above process, after the servo electric cylinder drives the retaining ring to complete all pressing actions, the force sensor continues to collect the final pressing force data at this time and records the data as the pressing force value F2; the displacement sensor synchronously acquires the actual displacement data of the retaining ring in the pressing completed state and records it as the displacement value S2, thus fully recording the key data of the pressing end point.

[0046] The actual displacement value S2 collected by the displacement sensor is accurately compared with the standard displacement value S set in the press-fitting stage to analyze the relationship between the two.

[0047] The pressing-in qualification of the retaining ring is determined based on the comparison results: if the displacement value S2 is less than the standard displacement value S, it indicates that the retaining ring has not reached the preset assembly depth, and it is determined that the retaining ring is not pressed in place; if the displacement value S2 is greater than or equal to the standard displacement value S, it indicates that the retaining ring has reached the design required assembly depth, and it is determined that the retaining ring is pressed in place. After completing the pressing-in qualification determination, the complete test data for this stage is output, including the pressing force value F2, the displacement value S2, and the pressing-in qualification determination result, i.e., the pressing-in detection data. If the determination result is that the pressing is qualified, a reset command will be sent to the servo cylinder to control the servo cylinder to return to the initial position with the power sensor, preparing for the next pressing operation; if the determination result is that the pressing is not in place, the servo cylinder will remain in the current state, waiting for the operator to perform subsequent processing.

[0048] Corresponding to the aforementioned embodiments of the brake pedal retainer pressing method, this application also provides embodiments of a brake pedal retainer pressing system.

Figure 6 The system may include: a pressing preset module 501, a pressing equipment start module 502, a pressing initial detection module 503, and a pressing completion detection module 504; wherein: The press-fit preset module 501 is used to preset the minimum press-fit force threshold Fmin, the maximum threshold Fmax, and the standard displacement value S for press-fitting according to the design dimensions of the retaining ring and the central rotating shaft. The press-fitting equipment start module 502 is used to place the retaining ring and the central rotating shaft at the designated assembly position and align them with the reference, start the servo electric cylinder to drive the power sensor and the retaining ring to move towards the central rotating shaft, and start the press-fitting process. The initial pressing detection module 503 is used to obtain the pressing force value F1 and displacement value S1 through a sensor when the retaining ring contacts and is pressed in, and to determine whether the size is qualified according to the pressing force value F1, the minimum threshold Fmin and the maximum threshold Fmax, and output the initial pressing detection data. The press-fit detection module 504 is used to acquire the press-fit force value F2 and displacement value S2 through a sensor after the press-fit action of the retaining ring is completed, and to determine whether the press-fit is qualified and whether the servo electric cylinder is reset based on the displacement value S2 and the standard displacement value S, and output the press-fit detection data.

[0050] In this embodiment, the press-fitting preset module 501 presets the minimum press-fitting force threshold Fmin, the maximum press-fitting force threshold Fmax, and the standard displacement value S for press-fitting completion based on the design dimensions of the retaining ring and the central rotating shaft. The press-fitting equipment start module 502 places the retaining ring and the central rotating shaft in the designated assembly position and aligns them with the reference, then starts the servo electric cylinder to move the power sensor and the retaining ring towards the central rotating shaft, thus initiating the press-fitting process. When the retaining ring contacts and is pressed into place, the press-fitting initial detection module 503 obtains the press-fitting force value F1 and the displacement value S1 through the sensor, and determines the appropriate displacement value based on the press-fitting force value F1 and the minimum press-fitting force threshold Fmax. The values ​​Fmin and Fmax are used to determine whether the dimensions are qualified and output the initial press-fit detection data. After the circlip press-fit action is completed, the press-fit completion detection module 504 obtains the press-fit force value F2 and displacement value S2 through the sensor, and determines whether the press-fit is qualified and whether the servo electric cylinder has been reset based on the displacement value S2 and the standard displacement value S, and outputs the press-fit completion detection data. In this way, the dimensional qualification and press-fit completion status can be detected simultaneously during the circlip press-fit process, thereby ensuring the structural stability of the brake pedal and improving the driver's driving experience and driving safety.

The brake pedal retainer press-fit method as described in claim 5, characterized in that, In the step of determining whether the dimensions of the retaining ring and the central rotating shaft match according to the comparison results, and outputting the complete inspection data for this stage, i.e., the initial inspection data of press-fitting, the process of determining whether the dimensions of the retaining ring and the central rotating shaft match according to the comparison results is as follows: If the pressing force F1 is between the minimum threshold Fmin and the maximum threshold Fmax, then the component size is deemed to be qualified.

7. The brake pedal retainer press-fit method as described in claim 1, characterized in that, After the circlip pressing action is completed, the pressing force value F2 and displacement value S2 are acquired by the sensor. Based on the displacement value S2 and the standard displacement value S, the system determines whether the pressing is qualified and whether the servo electric cylinder has reset, and outputs the pressing in place detection data. Once the pressing action of the retaining ring is completed, the force sensor collects the final pressing force data and records it as the pressing force value F2, and the displacement sensor simultaneously acquires the actual displacement data of the pressing completed state and records it as the displacement value S2. Compare the displacement value S2 with the standard displacement value S; Based on the comparison results, determine whether the retaining ring is properly pressed in, and output the complete test data for this stage, namely the press-in test data.
