Description

Technical Field

[0001] The invention relates to the technical field of IPB parking force detection equipment, in particular to an IPB parking force detection platform. Background Art

[0002] In the field of automobile braking systems, the functional test of IPB parking brakes is of vital importance, as it is directly related to the safety and reliability of vehicle parking. At present, when performing functional tests on IPB parking brakes, the test bench mainly uses rigid fastening methods (such as fastening screws) and pneumatic fastening methods to fix the test piece; among them, the pneumatic fastening method is widely used because it can effectively offset the large reaction force generated by the test when testing a large parking force, thereby ensuring the smooth progress of the test.

[0003] In the actual operation process of the prior art, operators often focus on eliminating other interfering factors that affect the tightening of the workpiece to be tested, such as the flatness of the surface of the test table and the fit between the fixture and the workpiece to be tested; however, it is very easy to ignore the connection between the air pump and the fastener; the connection between the air pump and the fastener involves the key aspects of air tightness and the integrity of the connection components themselves. If the connection is not airtight, such as improper installation causing gas leakage, or damage or damage between the connection components, such as the connection joint being damaged due to thread slippage and loosening due to stress on the thread, it will seriously affect the final tightening effect of the pneumatic fixing method.

[0004] When the fastening becomes loose, the functional test of the IPB parking brake will firstly lead to inaccurate test data; because the test piece is not stably fixed, it will produce additional displacement and shaking under the action of the test force, which will cause the parking force value obtained by the test equipment to deviate and fail to truly reflect the actual performance of the IPB parking brake, thus leading to misjudgment of product quality; secondly, the loose fastening state will cause the test piece to fall off or shift during the test, which will not only damage the test equipment, increase the maintenance cost of the equipment and interrupt the test, delay the production progress, but also the fallen test piece will increase the safety hazard to the operator.

[0005] In addition, when the connecting air pipe is loose, the gas sealing is destroyed, which will lead to unstable or insufficient pneumatic fastening force. This makes it impossible for the test piece to be reliably fixed during the test process. When the test piece is subjected to force, it will produce additional displacement and shaking due to loose fixation, which will lead to an erroneous assessment of product quality. At the same time, the loose air pipe will cause gas leakage, affecting the pressure balance of the entire pneumatic system and even causing malfunction of the pneumatic components. The bending of the connecting air pipe will limit the smooth flow of gas, making it impossible for the pneumatic fastening device to obtain sufficient air pressure to provide a stable fastening force. This will not only cause the test piece to be loosely fixed, resulting in inaccurate test data problems similar to loose air pipes, but also form local high pressure due to the obstruction of gas flow, causing damage to the air pipe and other pneumatic components, increasing equipment maintenance costs and downtime. The above problems will cause physical damage to the testing equipment, increase equipment maintenance costs and interrupt the testing process, delaying production plans; and the fallen test piece will also pose a serious threat to the personal safety of operators.

[0006] Therefore, the present invention proposes an IPB parking force detection platform to solve the above problems. Summary of the invention

[0023] Compared with the prior art, the present invention provides an IPB parking force test bench, which has the following beneficial effects: 1. The present invention improves the design of the test assembly by connecting components, and can test the air tightness of the components required for the test bench before the parking brake test piece is tested, which brings many significant benefits to the parking brake detection of the prior art.

[0024] First, in terms of detection accuracy, by testing the air tightness of the components in advance, it is possible to effectively avoid the phenomenon of loose fixation of the test piece caused by the looseness of the air pipe connecting the air pump and the fasteners, that is, the fixture; it can ensure that during the detection process, the test piece is always in a stable and reliable fixed state, greatly reducing the additional displacement and shaking caused by unstable fixation, so that the detection equipment can obtain accurate parking force values, truly reflect the actual performance of the IPB parking brake, significantly reduce the possibility of misjudgment of product quality, and improve the credibility and effectiveness of the test results.

[0025] In terms of improving production efficiency, by improving detection accuracy, repeated detection work due to misjudgment can be reduced; by protecting equipment, downtime caused by equipment failure can be effectively reduced; by ensuring personnel safety, production interruptions due to safety accidents can be avoided; secondly, from the perspective of equipment protection, this component can promptly detect and eliminate pneumatic system anomalies caused by airtightness problems before detection, such as pressure imbalance caused by gas leakage or the risk of damage to connecting air pipes and other pneumatic components due to local high pressure; this helps to extend the service life of the detection equipment, reduce the failure rate and maintenance frequency of the equipment, reduce the maintenance cost and downtime caused by equipment damage, ensure the continuity and efficiency of the detection work, and provide stable and reliable equipment support for production operations.

[0026] 2. The present invention can not only test the air tightness of the device before testing through the setting of the test plate and the auxiliary observation strip, but also enable the operator to indirectly judge whether the second main body shell and the threaded port have moved, that is, whether they are loose, or whether the above-mentioned components are damaged due to gas pressure and thread deformation, that is, stripping, during the parking brake test by observing the position changes of the test plate and the auxiliary observation strip; and the above-mentioned position observation of the test plate and the auxiliary observation strip is different from the method of drawing vertical line marks on two or more components in the prior art, avoiding the disadvantage of the latter being erased; this design can only provide support for component testing before testing, and can also provide auxiliary design during testing, further improving the detection efficiency of the parking brake, saving the number of components, and improving the perfection of the overall work.

[0027] 3. The present invention can improve the detection stability and accuracy and enhance the compatibility and adaptability of the equipment during the IPB parking brake performance test through the design of the conveying stability component. The specific effects are as follows: This component can stably fix the connecting air pipe required for the operation of the test bench, effectively preventing the connecting air pipe from loosening during the test process, which enables the pneumatic fixing method to stably maintain the fastening force of the test piece, so that the test piece will not produce unnecessary displacement and shaking due to the problem of the connecting air pipe during the test process, ensuring that the testing equipment can accurately measure the various performance parameters of the IPB parking brake, especially greatly improving the accuracy of the parking force value detection; avoiding the deviation of the test data caused by the instability of the connecting air pipe, reducing the risk of misjudgment of the product quality, making the test result more reliable and authoritative, and providing a solid guarantee for the quality control of the parking brake.

[0028] In addition, since the fastening arc plate can be moved by the sliding strip, the compatibility and adaptability of the equipment can be enhanced in fixed work. That is, whether in the IPB parking brake detection scenarios of different models or specifications, or when the connecting air pipes used in the test bench have changed in diameter due to upgrades or special needs, this component can be well adapted. There is no need to frequently replace or adjust the fixing devices for connecting air pipes of different diameters, which reduces the equipment modification and maintenance costs, improves the overall versatility and flexibility of the test bench, and can better meet diverse detection needs and adapt to the ever-changing technical requirements of the automotive brake system industry.

[0029] 4. The present invention adds a design of an adapter column. In addition to tightening the connecting air pipe by the tightening arc plate and providing it with the necessary tightening support surface; because the adapter column itself has a length and is placed in the connecting air pipe in a plug-in manner, it can effectively avoid bending at the connection between the connecting air pipe and the conveying stability component when the device is tested, thereby improving the gas delivery work, ensuring the stability of gas delivery, and effectively preventing the impact of excessive local air pressure on the connecting air pipe itself and the connected pneumatic components due to the bending of the connecting air pipe, as well as the accelerated wear and aging caused by frequent shaking and friction of the connecting air pipe; by reducing these potential equipment damage factors, the failure rate of each component of the pneumatic system is significantly reduced, the overall service life of the test bench is extended, the long-term investment cost of the enterprise in equipment purchase, maintenance and renewal is reduced, and the return on investment of the equipment is improved.

[0047] The component connection improvement test assembly 5 is used to perform a performance test on the connection airtightness components of the fixture 4 before the test piece is tested; in order to avoid insufficient tightness caused by loose connection, which may lead to loosening of the test piece during testing, and at the same time, it can provide lateral feedback to see whether there is a thread slippage problem between the threaded connection between the connecting bridge block 502 and the threaded through-piece 506; and it can monitor whether thread slippage occurs.

[0055] For further examples, please refer to Figure 2 , Figure 3 , Figure 8 , Fig. 9 As shown: the delivery stability component 6 is used to adapt and stabilize the connecting air pipes 3 of different diameters, and can ensure that the connecting tail ends do not bend during use, thereby ensuring a stable gas delivery state. The delivery stability component 6 includes a guide plate 601 fixed in the inner cavity of the first main body shell 501, and guide grooves 602 are equidistantly provided on the guide plate 601. A sliding bar 603 is slidably connected in the guide groove 602.

Arc grooves 608 are equidistantly provided on the adjusting plate 607. An adapting column 609 is provided in the connecting air pipe 3, and air flow holes 610 are equidistantly provided on the adapting column 609.

[0056] Among them: the delivery stability component 6 is used to adapt and stabilize the connecting gas pipes 3 of different diameters, and can ensure that the connecting tail end does not bend during use, thereby ensuring a stable gas delivery state.

[0057] The sliding bar 603 is matched with the guide channel 602 .

[0058] The connecting bridge block 502 is provided with a column rod which can be inserted into the hole provided on the friction ring 606 to fix the adjusting disk 607 after rotation.

[0059] The sliding post 604 is slidably matched with the arc-shaped groove 608 .

[0060] The outer diameter of the adapter column 609 is consistent with the inner diameter of the connecting air pipe 3.

[0061] The gas flow holes 610 are mainly used for the stable flow of the gas delivered from the connecting gas pipe 3 .

[0062] The working principles of all the contents in the above embodiments are as follows: in the initial state: the plug-in strip 509 is not magnetically attracted by the magnet 505, the arc-shaped cavity piece 508 is not assembled on the second main body shell 503, the reset spring 511 and the limit spring 516 are not compressed, no solution is injected into the closed solution chamber formed by the fixed connection between the arc-shaped cavity piece 508 and the silicon capsule piece 510, and the test plate 512 and the auxiliary observation strip 513 are not in the same plane.

[0063] The following is the working process of the component connection and improvement test assembly 5: It should be noted that the test framework is: after fixing the device components, inject the corresponding solution into the solution tank composed of the silicon capsule sheet 510 and the arc-shaped cavity piece 508, so that the test plate 512 and the auxiliary observation strip 513, which are not in the same plane at the beginning, are in the same plane. For example, after injecting 5ml of solution, the two are in the same plane; further, the ventilation control tightening action is implemented through the storage gas tank 2, and the relative position of the test plate 512 and the auxiliary observation strip 513 is observed to see if there is any change, so as to determine whether there is any looseness in the connection between the components.

[0064] Specifically, when in use, first, the ring formed by the arc-shaped cavity piece 508 is sleeved on the work fixture 4 fixedly connected to the work fixture 4, and then, the operator rotates the second main body shell 503 to make it threadedly fixedly connected to the threaded through-piece 506. At this time, the second main body shell 503 and the arc-shaped cavity piece 508 need to be installed in combination. Specifically; the operator inserts the connecting strip 509 movably plugged into the arc-shaped cavity piece 508 into the connecting groove 504 provided on the second main body shell 503. When plugging in, the connecting strip 509 made of metal will be magnetically fixed by the magnet 505 in the connecting groove 504. At this point, the second main body shell 503 and the ring formed by the arc-shaped cavity piece 508 are fixed.

[0065] Furthermore, after the fixation is completed, the air tightness test of the device can be carried out before operation; first, the solution is injected into the solution chamber composed of the arc-shaped cavity piece 508 and the silicon capsule piece 510 through the injection needle, for example, 5 ml of solution is injected therein, at this time, the test plate 512 and the auxiliary observation strip 513 which are not initially on the same plane will be on the same plane, and the silicon capsule piece 510 and the rectangular parallelepiped of the test piece 507 are distributed in the upper and lower positions; further, the ventilation control tightening action is implemented through the storage gas tank 2, and the test is observed. Whether the relative position of the test plate 512 and the auxiliary observation bar 513 changes, there are two state changes at this time; first, the test plate 512 still overlaps with the auxiliary observation bar 513, which indicates that the connection between the second main body shell 503 and the fixedly connected arc cavity piece 508 and the threaded through-hole piece 506 is not loose; second, the test plate 512 does not overlap with the auxiliary observation bar 513, which indicates that the connection between the second main body shell 503 and the fixedly connected arc cavity piece 508 and the threaded through-hole piece 506 is loose.

[0066] For further information, please refer to the attached Figure 4 And attached Figure 5 If the connecting air pipe 3 becomes loose, or when the second main body shell 503 and the threaded port piece 506 which are indirectly fixedly connected to the connecting air pipe 3 move relative to each other, the second main body shell 503 will move with the arc cavity piece 508 fixedly connected thereto in a direction away from the threaded port piece 506, and the silicon capsule piece 510 on the arc cavity piece 508 will change its relative position with the test piece 507 on the threaded port piece 506. As is known, the test piece 507 is composed of a triangular block and a rectangular block. In this change, the silicon capsule piece 510 will gradually move from the rectangular block position with the test piece 507 to the middle of it. The position of the triangular block is located. During this process, the triangular block of the test piece 507 will squeeze the silicon capsule sheet 510. At this time, the solution in the solution tank composed of the arc-shaped cavity piece 508 and the silicon capsule sheet 510 will further push the test plate 512 therein. At this time, the test plate 512 will move to both ends of the arc-shaped cavity piece 508. At this time, the reset spring 511 is compressed again, and the test plate 512 will no longer be seen in the area on the arc-shaped cavity piece 508 made of transparent plastic material. At this time, the loose feedback change work is completed; that is, the operator can judge whether looseness has occurred between the components at this time by observing the changes in the transparent area of ​​the arc-shaped cavity piece 508.

[0067] Furthermore, the setting of the test plate 512 and the auxiliary observation strip 513 can not only test the air tightness of the device before the inspection work; during the parking brake inspection, the operator can also indirectly judge whether the second main body shell 503 and the threaded through-piece 506 are moved, that is, whether they are loose, or judge whether the above-mentioned components are damaged due to gas pressure and thread deformation, that is, thread slippage, by observing the position of the test plate 512 and the auxiliary observation strip 513. The above-mentioned position observation of the test plate 512 and the auxiliary observation strip 513 is different from the existing technology of drawing vertical line marks on two or more components, avoiding the disadvantage of the latter being erased. This design can only provide support for component testing before inspection and can also provide assistance during inspection, further improving the inspection efficiency of the parking brake, saving the number of components and improving the perfection of the overall work.

[0068] Furthermore, by improving the design of the test assembly 5 through component connection, the air tightness of the components required for the operation of the test bench 1 can be tested before the parking brake test piece is tested. That is, in terms of detection accuracy, by testing the air tightness of the components in advance, it is possible to effectively avoid the phenomenon of loose fixation of the test piece due to looseness of the connecting air pipe 3 between the air pump and the fastener, that is, the fixture 4; it can ensure that during the detection process, the test piece is always in a stable and reliable fixed state, greatly reducing the additional displacement and shaking caused by unstable fixation, so that the detection equipment can obtain accurate parking force values, truly reflect the actual performance of the IPB parking brake, significantly reduce the possibility of misjudgment of product quality, and improve the credibility and effectiveness of the detection results.

[0069] In terms of improving production efficiency, by improving detection accuracy, repeated detection work due to misjudgment can be reduced; by protecting equipment, downtime caused by equipment failure can be effectively reduced; by ensuring personnel safety, production interruptions due to safety accidents can be avoided; secondly, from the perspective of equipment protection, this component can promptly detect and eliminate pneumatic system anomalies caused by airtightness problems before detection, such as pressure imbalance caused by gas leakage or damage risk to connecting air pipe 3 and other pneumatic components due to local high pressure; this helps to extend the service life of the detection equipment, reduce the failure rate and maintenance frequency of the equipment, reduce the maintenance cost and downtime caused by equipment damage, ensure the continuity and efficiency of the detection work, and provide stable and reliable equipment support for production operations.

[0070] Please refer to the above working process Figures 1 to 7 .

[0071] The following is the working process of the conveying stability component 6: when in use, first, the adapter column 609 is inserted into the connecting air pipe 3, and then the connecting air pipe 3 with the adapter column 609 is inserted into the central hole on the first main body shell 501, and then further, the adjusting disk 607 is rotated with the assistance of the friction ring 606. At this time, the sliding bar 603 slidably connected in the guide groove 602 on the guide plate 601 will interact with the arc groove 608 provided on the adjusting disk 607 and the adapter column 609 during the rotation of the adjusting disk 607, that is, when the adjusting disk 607 is rotated During rotation, the adapter column 609 in the arc groove 608 will slide with the sliding bar 603 in the guide groove 602, that is, at this time, the sliding bar 603 of the sliding connection will bring the fastening arc plate 605 to fasten and clamp the connecting air pipe 3 under the action of the adapter column 609 plugged in the connecting air pipe 3. Furthermore, after the fastening arc plate 605 fastens and clamps the surface of the connecting air pipe 3, the column rod set on the connecting bridge block 502 is inserted into the hole opened on the friction ring 606 to fix the rotated adjusting disk 607, and the fastening operation is completed.

[0072] Furthermore, by adding the design of an adapter column 609, in addition to tightening the connecting air pipe 3 by tightening the arc plate 605 and providing it with the necessary tightening support surface; since the adapter column 609 itself has a length and is placed in the connecting air pipe 3 in a plug-in manner, it can effectively avoid the bending of the connection between the connecting air pipe 3 and the conveying stability component 6 when the device is tested, thereby improving the gas delivery work, ensuring the stability of gas delivery, and effectively preventing the impact of excessive local air pressure on the connecting air pipe 3 itself and the connected pneumatic components caused by the bending of the connecting air pipe 3, as well as the accelerated wear and aging caused by the frequent shaking and friction of the connecting air pipe 3; by reducing these potential equipment damage factors, the failure rate of each component of the pneumatic system is significantly reduced, the overall service life of the test bench 1 is extended, the long-term investment cost of the enterprise in equipment purchase, maintenance and renewal is reduced, and the return on investment of the equipment is improved.

[0073] Furthermore, through the design of the conveying stability component 6, when the IPB parking brake performance is tested, this component can stably fix the connecting air pipe 3 required for the operation of the test bench 1, thereby improving the detection stability and accuracy, enhancing the compatibility and adaptability of the equipment, and effectively preventing the connecting air pipe 3 from loosening during the detection process. This allows the pneumatic fixing method to stably maintain the tightening force of the test piece, so that the test piece will not produce unnecessary displacement and shaking due to problems with the connecting air pipe 3 during the detection process, ensuring that the testing equipment can accurately measure the various performance parameters of the IPB parking brake, especially greatly improving the accuracy of the parking force value detection; avoiding the deviation of the test data caused by the instability of the connecting air pipe 3, reducing the risk of misjudgment of product quality, making the test results more reliable and authoritative, and providing a solid guarantee for the quality control of the parking brake.

[0074] In addition, since the fastening arc plate 605 can be moved by the sliding bar 603, the compatibility and adaptability of the equipment can be enhanced during fixed work. That is, whether in the IPB parking brake detection scenarios of different models or specifications, or when the connecting air pipe 3 used in the test bench 1 changes its diameter due to upgrading or special needs, this component can be well adapted, and there is no need to frequently replace or adjust the fixing device for the connecting air pipe 3 of different diameters, thereby reducing the equipment modification and maintenance costs, improving the overall versatility and flexibility of the test bench 1, and being able to better meet diverse detection needs and adapt to the continuously developing and changing technical requirements of the automotive brake system industry.
