Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, specifically to a brake drum assembly brake surface runout detection device. Background Technology

[0002] As a core component of a vehicle's braking system, the brake drum assembly's brake surface runout accuracy directly determines the vehicle's overall braking performance. For commercial vehicles, the industry generally requires the brake surface runout to be controlled within 0.2mm. If this standard is not met, it can easily lead to insufficient braking force, one-sided braking, and other braking failures, seriously threatening driving safety. Therefore, whether in after-sales troubleshooting or in the full inspection process after production line completion, the test of the brake surface runout of the brake drum assembly relative to the wheel hub centerline is indispensable.

[0003] Current testing solutions on the market have significant shortcomings and fail to meet actual needs. In after-sales maintenance scenarios, existing equipment can only detect single-point or single-line runout of the brake surface, and cannot identify situations where the brake surface is worn into a conical shape, significantly increasing maintenance difficulty, cost, and time. In production line testing scenarios, existing solutions also have deficiencies. Some companies use lathe fixtures to clamp the brake drum assembly and mount testing instruments on a support plate for inspection; however, the lathe spindle's own errors and fixture installation errors are directly transmitted to the testing data, resulting in low measurement accuracy and an inability to accurately determine product qualification. A few other companies use online photo analysis technology, which can improve testing accuracy, but the equipment purchase and maintenance costs are extremely high, making it difficult to popularize in small and medium-sized production lines and hindering the overall improvement of testing efficiency in the industry.

[0004] In summary, existing brake drum assembly brake surface runout detection solutions suffer from incomplete detection, low accuracy, and high cost. There is an urgent need for a detection device that balances detection accuracy, ease of operation, and cost-effectiveness to meet the actual needs of after-sales maintenance and production line full inspection.

[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Example

[0026] like Figures 1 to 6 As shown, this embodiment discloses a brake drum assembly brake surface runout detection device, comprising: Mounting platform 10; Rotary mounting assembly 11, which is mounted on the mounting platform 10 for mounting the brake drum assembly; Height adjustment component 12 is disposed on mounting platform 10 and located on one side of rotating mounting component 11, and is used to install detection component 13 and adjust the height of detection component 13; The detection component 13 is mounted on the height adjustment component 12 at one end and is configured to cooperate with the rotary mounting component 11 at the other end, and is used to detect the brake surface of the brake drum assembly. The height adjustment component 12 includes a mounting base 14, a threaded lifting structure 15, and an adsorption panel 16. The mounting base 14 is mounted on the mounting platform 10 and is detachably connected to the mounting platform 10. The threaded lifting structure 15 is mounted on the mounting base 14 and is detachably connected to the mounting base 14. The adsorption panel 16 is mounted on the threaded lifting structure 15 and is detachably connected to the threaded lifting structure 15. One end of the detection component 13 is mounted on the adsorption panel 16 and is detachably connected to the adsorption panel 16.

[0027] In use, this invention first mounts the brake drum with hub assembly onto the rotating mounting assembly 11. Then, the detection assembly 13 is mounted onto the height adjustment assembly 12. The position of the detection assembly 13 is adjusted by the height adjustment assembly 12 so that it is positioned above the brake surface of the brake drum. Simultaneously, the detection assembly 13 is adjusted to mate with the brake surface of the brake drum. The position of the detection assembly 13 is then further adjusted by the height adjustment assembly 12, moving it from the top to the bottom of the brake surface. During this process, the brake drum is continuously rotated. The detection error of the detection assembly 13 represents the runout data of the entire brake surface of the hub assembly in both the circumferential and linear directions. Compared to traditional technologies, this invention effectively solves the problems of incomplete detection, low accuracy, and high cost associated with current brake drum assembly brake surface runout detection technologies.

[0028] To facilitate obtaining the detection error value and to facilitate the installation of the detection component 13, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that the detection component 13 includes a magnetic base 17 and a dial gauge 18. The adsorption panel 16 is a metal material that can be adsorbed by the magnetic base 17. One end of the magnetic base 17 is adsorbed on the adsorption panel 16, and the dial gauge 18 is installed at the other end of the magnetic base 17.

[0029] The testing component 13 combines a magnetic base 17 and a dial indicator 18. One end of the magnetic base 17 is attached to a metal adsorption panel 16, and the other end is fitted with the dial indicator 18. Utilizing the properties of magnetic adsorption, quick installation and position adjustment are achieved. Simultaneously, the magnetic base 17 itself has an orientation function, ensuring effective contact between the dial indicator 18 and the brake surface of the brake drum assembly. The dial indicator 18 can directly read the testing error value, simplifying the installation process of the testing component 13 and providing convenient and accurate error data, thus improving the flexibility and efficiency of the testing.

[0030] The adsorption panel 16 can be made of iron.

[0031] To facilitate the lifting and lowering of the detection component 13, this embodiment is an improvement upon the above embodiment. The difference lies in that the threaded lifting structure 15 includes a track mounting plate 19, a threaded rotating rod 20, a threaded connecting block 21, and a pair of fixed mounting plates 22. The pair of fixed mounting plates 22 are respectively disposed at both ends of the track mounting plate 19 and are detachably connected to the track mounting plate 19 by bolts. The track mounting plate 19 is vertically mounted on the mounting base 14, and the fixed mounting plate 22 located at the bottom of the track mounting plate 19 is detachably connected to the mounting base 14 by bolts. The threaded rotating rod 20 is disposed on one side of the track mounting plate 19. A pair of fixed mounting plates 22 pass through both ends of the threaded rod 20 and are rotatably connected to the fixed mounting plates 22. A threaded connecting block 21 is sleeved on the threaded rotating rod 20 and is threadedly connected to the threaded rotating rod 20. The threaded connecting block 21 is clearance-fitted with the track mounting plate 19. One side of the adsorption panel 16 is detachably connected to the threaded connecting block 21 by bolts. A pair of sliding limiting members 23 are provided between the adsorption panel 16 and the track mounting plate 19 to limit the rotation of the adsorption panel 16. The pair of sliding limiting members 23 are located on both sides of the threaded rotating rod 20 and are clearance-fitted with the threaded connecting block 21. The sliding limiting members 23 are detachably connected to the adsorption panel 16 and the track mounting plate 19 respectively.

[0032] The threaded lifting structure 15 is connected by a track mounting plate 19, a threaded rotating rod 20, a threaded connecting block 21, and a pair of fixed mounting plates 22. The fixed mounting plates 22 support the threaded rotating rod 20 and are detachably connected to the track mounting plate 19 and the mounting base 14. When the threaded rotating rod 20 is rotated, the threaded connecting block 21 drives the adsorption panel 16 to rise and fall along the track mounting plate 19. The sliding limiters 23 on both sides restrict the rotation of the adsorption panel 16. This structure can not only accurately adjust the height of the detection component 13 to adapt to different detection needs, but also facilitate assembly and maintenance, and ensure that the lifting process is stable and reliable.

[0033] As a further preferred embodiment, the sliding limit member 23 includes a limit slide rail 24 and a pair of limit sliders 25. The limit slide rail 24 is disposed on the track mounting plate 19 and is detachably connected to the track mounting plate 19 by bolts. One side of the pair of limit sliders 25 is respectively engaged with the limit slide rail 24 and slidably connected to the limit slide rail 24. The other side of the pair of limit sliders 25 is detachably connected to the adsorption panel 16 by bolts.

[0034] The sliding limit component 23 consists of a limit slide rail 24 and a pair of limit sliders 25. The limit slide rail 24 is fixed on the track mounting plate 19. One side of the limit slider 25 is slidably connected to the slide rail, and the other side is connected to the adsorption panel 16. Through the cooperation between the slider and the slide rail, the rotational freedom of the adsorption panel 16 is effectively constrained, ensuring that it rises and falls smoothly with the threaded connecting block 21. At the same time, the bolt connection design facilitates the installation and replacement of components, improving the practicality of the structure.

[0035] As a further preferred embodiment, each of the pair of fixed mounting plates 22 is provided with a connecting bearing 26, and the two ends of the threaded rotating rod 20 are respectively rotatably connected to the pair of fixed mounting plates 22 through the connecting bearing 26. The threaded rotating rod 20 passes through the inner ring of the connecting bearing 26 and is fixedly connected to the inner ring of the connecting bearing 26. The outer ring of the connecting bearing 26 is fixedly connected to the fixed mounting plate 22.

[0036] A pair of connecting bearings 26 on the fixed mounting plate 22 enable the two ends of the threaded rod 20 to be rotatably connected to the fixed mounting plate 22 respectively. The inner ring of the bearing is fixed to the threaded rod 20 and the outer ring is fixed to the fixed mounting plate 22, which converts sliding friction into rolling friction, greatly reduces the rotational resistance of the threaded rod 20, makes it rotate more smoothly, reduces component wear, and extends the service life of the structure.

[0037] As a further preferred embodiment, a rotating handwheel 27 is provided at one end of the threaded rod 20. The rotating handwheel 27 is located on the top of the track mounting plate 19 and is fixedly connected to the threaded rod 20 for driving the threaded rod 20.

[0038] The rotating handwheel 27 at the top of the threaded rotating rod 20 is fixedly connected to the rotating rod. The threaded rotating rod 20 can be driven to rotate by manually rotating the rotating handwheel 27, providing a convenient operating fulcrum for the rotating rod. This allows the operator to accurately control the lifting height of the adsorption panel 16, reducing the difficulty of adjustment and improving the convenience and efficiency of operation.

[0039] To facilitate the loading, unloading, and rotation of the brake drum assembly, this embodiment is an improvement upon the above embodiment. The difference lies in that the rotating mounting assembly 11 includes a spindle 28, an inner ring bearing 29, an outer ring bearing 30, a transition sleeve 31, and a locking structure 32. The spindle 28 is mounted on the mounting platform 10 and is detachably connected to the mounting platform 10 via bolts. The inner ring bearing 29 is fitted onto the lower end of the spindle 28 and is detachably connected to the spindle 28. The outer ring bearing 30 is fitted onto the lower end of the transition sleeve 31 and is detachably connected to the transition sleeve 31. The transition sleeve 31 is fitted onto the upper end of the spindle 28 and is detachably connected to the spindle 28. The brake drum assembly is fitted onto the outside of the spindle 28, the inner ring bearing 29, and the outer ring bearing 30. The brake drum assembly is rotatably connected to the spindle 28 via the inner ring bearing 29 and to the transition sleeve 31 via the outer ring bearing 30. The locking structure 32 is located on the top of the spindle 28 and is used to restrict the brake drum assembly onto the spindle 28.

[0040] In the rotating mounting assembly 11, the spindle 28 is fixed on the mounting platform 10. The brake drum assembly is rotatably connected to the spindle 28 through the inner ring bearing 29 and the outer ring bearing 30 and the transition sleeve 31. The transition sleeve 31 is fitted on the spindle 28. The locking structure 32 at the top restricts the axial displacement of the brake drum assembly. The double bearing cooperation ensures the stable rotation of the brake drum assembly. The detachable connection design facilitates its quick installation and removal. It can also adapt to different specifications of test objects by replacing bearings of different specifications, ensuring the stability and accuracy of the test process.

[0041] As a further preferred embodiment, the locking structure 32 includes an open washer 33 and a locking sleeve 34. The open washer 33 is sleeved on the spindle 28 and is detachably connected to the spindle 28. The open washer 33 is located above the transition sleeve 31. The locking sleeve 34 is sleeved on the spindle 28 and is threadedly connected to the spindle 28. The locking sleeve 34 is located above the open washer 33, and one end abuts against the open washer 33.

[0042] The open washer 33 of the locking structure 32 is fitted on the spindle 28 and located above the transition sleeve 31. The locking sleeve 34 is threadedly connected to the spindle 28 and abuts against the open washer 33. By tightening the locking sleeve 34, the open washer 33 is squeezed, and its elastic deformation is used to axially lock the brake drum assembly. The threaded connection facilitates tightness adjustment, and the elastic locking can compensate for the gap, ensuring that the brake drum assembly does not loosen during testing, thus balancing locking reliability and ease of operation.

[0043] To improve the ease of installation, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that the mounting base 14 and the mounting platform 10 are detachably connected by bolts.

[0044] It also includes a mounting table 35, on which the mounting platform 10 is mounted and detachably connected to the mounting table 35 by bolts.

[0045] The mounting base 14 and the mounting platform 10, as well as the mounting platform 10 and the mounting table 35, are detachably connected by bolts. This connection method facilitates the assembly, disassembly, and transportation of the overall structure, adapts to the adjustment needs of different usage scenarios, and facilitates the maintenance or replacement of individual components, reducing maintenance costs and improving the applicability of the equipment.

[0046] Working principle of this utility model: First, the brake drum with hub assembly is fixed by rotating mounting assembly 11. The brake drum assembly is sleeved on the outside of spindle 28, inner ring bearing 29 and outer ring bearing 30. Flexible rotation is achieved by rotating inner ring bearing 29 with spindle 28 and outer ring bearing 30 with transition sleeve 31. Then, the brake drum assembly is axially locked by locking structure 32 at the top of spindle 28 to ensure that it does not move axially during the test and can only rotate stably around spindle 28.

[0047] Subsequently, the detection component 13 is installed, the magnetic base 17 is attached to the metal adsorption panel 16, and the dial indicator 18 is installed at the other end of the magnetic base 17. The position of the dial indicator 18 is adjusted by using the orientation function of the magnetic base 17 so that it contacts the brake surface of the brake drum, thus completing the quick installation and alignment of the detection component 13.

[0048] During testing, the height adjustment component 12 controls the lifting and lowering of the testing component 13 in coordination with the rotation of the brake drum. The rotating handwheel 27 at the top of the threaded rod 20 is rotated to drive the threaded rod 20 to rotate. Under the action of the threaded connection, the threaded connecting block 21 drives the adsorption panel 16 and the testing component 13 to rise and fall vertically along the track mounting plate 19. The sliding limiters 23 on both sides ensure that the adsorption panel 16 only makes linear movement and does not rotate with the rod. At the same time, the operator continuously rotates the brake drum assembly, so that the dial indicator 18 continuously detects and records the runout error in the circumferential direction of the brake surface and the runout data at different heights during the linear lifting and lowering process as the adsorption panel 16 moves from the upper side of the brake drum brake surface to the lower side. Finally, the complete runout error of the brake surface of the brake drum assembly in the circumferential and linear directions is obtained, so as to achieve comprehensive and accurate testing.

[0049] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
