Description

Technical Field

[0001] This utility model relates to the field of brake disc processing technology, and in particular to a flatness detection device for automotive brake disc processing. Background Technology

[0002] During the manufacturing process of automotive brake discs, flatness is a key factor in ensuring braking performance and safety. Traditional flatness testing methods usually rely on manual measurement or simple tools, which are low in accuracy and efficiency. In order to improve testing accuracy and production efficiency, a special flatness testing device has been developed, which can measure the flatness of brake discs in real time and accurately, ensuring the stability of product quality and performance.

[0003] However, in actual use, the following shortcomings still exist. For example, existing flatness inspection devices for automotive brake disc processing cannot achieve rapid positioning and automatic flatness inspection of brake discs, thus failing to improve inspection efficiency and accuracy. The inspection efficiency is low, manual positioning and operation are time-consuming, which restricts the production line cycle and reduces overall capacity. Frequent manual intervention leads to unstable inspection accuracy, making it easy to miss or misjudge due to human error, affecting the consistency of brake disc quality, increasing the risk of defective products entering the market, and potentially causing abnormal brake noise, vibration, or even brake failure due to substandard flatness, threatening driving safety. The labor cost is high and it is difficult to adapt to the needs of mass production, weakening the competitiveness of enterprises.

[0004] Therefore, this utility model proposes a flatness detection device for automobile brake disc processing to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a flatness testing device for automotive brake disc processing.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a flatness detection device for automotive brake disc processing, including a base plate, and further comprising:

[0007] A flatness detection component includes a support base connected to a base plate, an electric push rod mounted on the top of the support base, a housing connected to the output end of the electric push rod, a drive motor installed inside the housing, a connecting plate connected to the bottom of the housing, a turntable connected to the output end of the drive motor, a detection wheel provided at the bottom of the turntable, and a sensor provided on the side of the connecting plate near the top of the detection wheel.

[0008] A clamping and positioning assembly includes a cylinder mounted on a base plate, a movable block connected to the output end of the cylinder, a mounting frame connected to the movable block, a servo motor mounted on the mounting frame, and a clamping plate provided at the output end of the servo motor.

[0009] Furthermore, a guide rod is slidably connected inside the turntable.

[0010] The beneficial effects of adopting the above-mentioned further solution are: the guide rod is slidably connected inside the turntable, so that the guide rod can move flexibly along the axis of the turntable. During the test, the guide rod rotates with the turntable and can slide up and down due to the undulation of the brake disc surface, providing stable guidance for the test wheel and ensuring that it always fits the disc surface, thus ensuring the stability and accuracy of the test.

[0011] Furthermore, the detection wheel is connected to the bottom of the guide rod.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the detection wheel is connected to the bottom of the guide rod and moves synchronously with the guide rod. When the guide rod moves up and down due to the influence of the disc surface, the detection wheel rolls closely against the surface of the brake disc, transmitting the change in flatness to the guide rod.

[0013] Furthermore, a telescopic spring is provided on the guide rod, and one end of the telescopic spring is connected to the turntable.

[0014] The beneficial effects of adopting the above-mentioned further solution are: one end of the telescopic spring on the guide rod is connected to the turntable, and the other end is connected to the guide rod. The elastic force of the telescopic spring makes the guide rod always have a downward tendency, ensuring that the detection wheel is in close contact with the surface of the brake disc, buffering the impact force on the detection wheel, and maintaining stable contact pressure.

[0015] Furthermore, the other end of the telescopic spring is connected to the guide rod.

[0016] The beneficial effects of adopting the above-mentioned further solution are: the two ends of the telescopic spring are respectively connected to the turntable and the guide rod to form an elastic connection structure. When the detection wheel encounters a protrusion, the guide rod moves up to stretch the telescopic spring. When it encounters a depression, the telescopic spring rebounds and pushes the guide rod down. The deformation of the telescopic spring absorbs the undulations of the disc surface, ensuring that the detection wheel adapts to the fit.

[0017] Furthermore, the output end of the servo motor is connected to a mounting block, and the clamping plate is connected to the mounting block.

[0018] The beneficial effects of adopting the above-mentioned further solution are: the servo motor output end is connected to the mounting block, the clamping plate is attached to the mounting block, the servo motor drives the mounting block to rotate, which in turn drives the clamping plate and the brake disc held to rotate, thereby realizing the switching of the detection surface and enabling the detection wheel to perform comprehensive detection on both sides of the brake disc, thus improving the detection coverage.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] In this invention, the device first fixes the brake disc using a clamping and positioning assembly. A cylinder drives a moving block to move the mounting bracket, bringing the clamping plate closer to and clamping the brake disc. A servo motor drives the brake disc to rotate, adjusting the detection surface. Subsequently, the flatness detection assembly is activated, the electric push rod extends, and the housing and bottom structure move downwards, causing the detection wheel to contact the brake disc surface. A transmission motor drives a turntable to rotate, causing the detection wheel to roll on the brake disc surface. When the brake disc surface is uneven, the detection wheel will move slightly up and down. The sensor on the connecting plate captures this change and converts the signal into an electrical signal, thereby completing the detection of the brake disc flatness. This achieves rapid positioning of the brake disc and automatic flatness detection, improving detection efficiency and accuracy. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1-5 As shown, this embodiment provides a technical solution: a flatness testing device for automotive brake disc processing, including a base plate 1, and further including:

[0032] Flatness detection component 2 includes a support base 21 connected to the base plate 1, an electric push rod 22 is installed on the top of the support base 21, the output end of the electric push rod 22 is connected to a housing 23, a drive motor 24 is installed inside the housing 23, a connecting plate 25 is connected to the bottom of the housing 23, a turntable 26 is connected to the output end of the drive motor 24, a detection wheel 28 is provided at the bottom of the turntable 26, and a sensor 210 is provided on the side of the connecting plate 25 near the top of the detection wheel 28.

[0033] The clamping and positioning assembly 3 includes a cylinder 31 mounted on a base plate 1. A movable block 32 is connected to the output end of the cylinder 31, and a mounting frame 33 is connected to the movable block 32. A servo motor 34 is mounted on the mounting frame 33, and a clamping plate 36 is provided at the output end of the servo motor 34. When the device is working, the brake disc is first fixed by the clamping and positioning assembly 3. The cylinder 31 drives the movable block 32 to move the mounting frame 33, causing the clamping plate 36 to approach and clamp the brake disc. The servo motor 34 can drive the brake disc to rotate to adjust the detection surface. When the rear flatness detection component 2 is activated, the electric push rod 22 extends, causing the housing 23 and bottom structure to move downwards, so that the detection wheel 28 contacts the surface of the brake disc. The drive motor 24 drives the turntable 26 to rotate, causing the detection wheel 28 to roll on the surface of the brake disc. When the surface of the brake disc is uneven, the detection wheel 28 will move up and down slightly. The sensor 210 on the connecting plate 25 captures this change and converts the signal into an electrical signal, thereby completing the detection of the flatness of the brake disc. This achieves rapid positioning of the brake disc and automatic detection of flatness, improving detection efficiency and accuracy.

[0034] like Figures 1-3As shown, a guide rod 27 is slidably connected inside the turntable 26, allowing the guide rod 27 to move flexibly along the axial direction of the turntable 26. During testing, the guide rod 27 rotates with the turntable 26 and simultaneously slides up and down due to the undulations of the brake disc surface, providing stable guidance for the detection wheel 28 and ensuring it always adheres to the disc surface, thus guaranteeing testing stability and accuracy. The detection wheel 28 is connected to the bottom of the guide rod 27 and moves synchronously with it. When the guide rod 27 moves up and down due to the influence of the disc surface, the detection wheel 28 rolls tightly against the brake disc surface, transmitting changes in flatness to the guide rod 27. A telescopic spring 29 is installed on the guide rod 27. One end is connected to the turntable 26. The telescopic spring 29 on the guide rod 27 is connected to the turntable 26 at one end and to the guide rod 27 at the other end. The elasticity of the telescopic spring 29 makes the guide rod 27 always have a downward tendency, ensuring that the detection wheel 28 is in close contact with the brake disc surface, buffering the impact force on the detection wheel 28, and maintaining stable contact pressure. The other end of the telescopic spring 29 is connected to the guide rod 27. The two ends of the telescopic spring 29 are respectively connected to the turntable 26 and the guide rod 27, forming an elastic connection structure. When the detection wheel 28 encounters a bulge, the guide rod 27 moves upward to stretch the telescopic spring 29. When it encounters a depression, the telescopic spring 29 rebounds and pushes the guide rod 27 downward. The deformation of the telescopic spring 29 absorbs the undulations of the disc surface, ensuring that the detection wheel 28 adapts to fit.

[0035] like Figure 1 as well as Figures 4-5 As shown, the output end of the servo motor 34 is connected to the mounting block 35, and the clamping plate 36 is connected to the mounting block 35. The servo motor 34 drives the mounting block 35 to rotate, which in turn drives the clamping plate 36 and the brake disc it holds to rotate, thereby achieving the switching of the detection surface. This allows the detection wheel 28 to perform comprehensive detection on both sides of the brake disc, improving the detection coverage.

[0036] Working principle:

[0037] like Figures 1-5As shown, when the brake disc flatness detection device is working, the clamping and positioning component 3 first fixes and adjusts the posture of the brake disc. The cylinder 31 on the base plate 1 drives the moving block 32 to move the mounting bracket 33 laterally, so that the clamping plate 36 on the mounting block 35 gradually approaches and clamps the brake disc, ensuring that the workpiece is stable and does not shift during the detection process. When it is necessary to switch the detection surface, the servo motor 34 starts, and drives the clamping plate 36 and the clamped brake disc to rotate synchronously through the mounting block 35, which can flexibly switch between the front and back sides to ensure that the detection covers the entire area of ​​the brake disc. Then, the flatness detection component 2 starts the detection process. The electric push rod 22 on the top of the support base 21 extends, pushing the housing 23 and the connecting plate 25 connected to the bottom to move down as a whole until the detection wheel 28 at the bottom of the guide rod 27 contacts the surface of the brake disc. At this time, the drive motor 24 drives the turntable 26 to rotate, causing the guide rod 27 and the detection wheel 28 to roll on the disc surface. Since the guide rod 27 and the turntable 26 are slidably connected and an elastic structure is formed between them by the telescopic spring 29, when the detection wheel 28 encounters a protrusion on the disc surface, the guide rod 27 slides upward along the axis of the turntable 26 and stretches the spring. When it encounters a depression, the spring rebounds and pushes the guide rod 27 downward, so that the detection wheel 28 always fits tightly against the disc surface, achieving adaptive following. The sensor 210 on the connecting plate 25 captures the micro-movements of the guide rod 27 in real time, converts the mechanical displacement into an electrical signal, and accurately judges the flatness of the brake disc surface by analyzing the signal changes. The whole process realizes the rapid positioning, automatic flipping and continuous detection of the brake disc, which greatly improves the detection efficiency and accuracy.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
