Description

Technical Field

[0001] The invention belongs to the technical field of brake disc polishing, in particular to a grinding device for rough processing of brake discs. Background Art

[0002] The brake disc is a vital component in the automobile braking system. Its performance and state directly affect the braking effect and safety of the vehicle. The preparation process of the brake disc generally includes the following steps: material selection; preparation of the mixture, forming and processing of the blank, and subsequent polishing and coloring; and in these processes, the polishing effect of the brake disc has an important impact on its braking performance during subsequent use. Most general brake disc polishing equipment uses a robot to clamp the processed brake disc to the polishing belt, polish it with the polishing belt, and after polishing, the robot puts down the brake disc, and the staff turns it over, and then the robot picks up the turned brake disc for another polishing. After polishing, the staff checks the flatness of the surface before moving to the next process.

[0003] In the prior art, when the polishing device performs a grinding operation on the brake disc body, it is usually limited to processing a single surface thereof. If the other side needs to be polished, the brake disc body must be removed first, and then re-clamped and positioned using the built-in manipulator of the polishing equipment. This repeated loading and unloading process greatly delays the overall progress of the polishing operation, resulting in a significant decrease in work efficiency. In addition, after the polishing of the brake disc body is completed, in order to avoid unevenness on its surface, manual visual inspection is usually required to evaluate the surface flatness of the brake disc body. This practice not only increases the labor intensity of the staff, but also increases the labor cost accordingly.

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] Reference Figure 1 - Fig.10 A grinding device for rough processing of brake discs comprises a polishing belt 1, a brake disc body 2, a transmission unit, a conveying unit and a detection unit; the conveying unit comprises a feed conveyor belt 4 and a discharge conveyor belt 5; the transmission unit comprises a conveyor belt 3 and a manipulator; the detection unit comprises a transfer component, a data acquisition component and a flipping component; the conveyor belt 3 is arranged on one side of the polishing belt 1, and there are multiple groups of manipulators, which are evenly arranged on the conveyor belt 3, and the manipulators can clamp and drive the brake disc body 2 to rotate and flip; the feed conveyor belt 4 is arranged on one side of the conveyor belt 3, and the discharge conveyor belt 5 is arranged on the conveyor belt On the other side of the conveyor belt 3, the feed conveyor belt 4 can convey the unpolished brake disc body 2 to the conveyor belt 3, and the discharge conveyor belt 5 can convey the polished brake disc body 2 away from the conveyor belt 3; there are two groups of transfer components, data acquisition components and flip components, which are sequentially arranged between the conveyor belt 3 and the discharge conveyor belt 5. The transfer component can transfer the polished brake disc body 2 from the conveyor belt 3 to the discharge conveyor belt 5, the data acquisition component can collect and analyze images of the surface of the polished brake disc body 2, and the flip component can turn over the polished brake disc body 2;

[0033] In this embodiment, a polishing belt 1, a brake disc body 2, a conveying unit, a delivery unit and a detection unit are provided. The delivery unit includes a feed conveyor belt 4 and a discharge conveyor belt 5. The unpolished brake disc body 2 is delivered to the conveyor belt 3 by the feed conveyor belt 4. The unpolished brake disc body 2 on the feed conveyor belt 4 is clamped and delivered to the polishing belt 1 by the conveyor belt 3 in cooperation with a manipulator. Thereafter, the brake disc body 2 continues to be moved along the polishing belt 1. During this process, the manipulator can drive the brake disc body 2 to rotate and flip, so that the polishing belt 1 can polish both sides of the brake disc body 2. When the manipulator moves the polished brake disc body 2 to the top of the transfer component with the manipulator, the manipulator puts down the brake disc body 2, and cooperates with the data acquisition component and the flipping component through the transfer component to realize the polishing of the brake disc body 2 in the process of transferring the brake disc body 2 to the discharge conveyor belt 5. The two sides are inspected to facilitate the staff to eliminate the brake disc body 2 with uneven surface after grinding. Finally, the brake disc body 2 is removed by the discharging conveyor belt 5. The structure in this embodiment effectively solves the problem in the prior art that the polishing device is usually limited to processing a single surface of the brake disc body 2 when performing the grinding operation on the brake disc body 2. If the other side needs to be polished, the brake disc body 2 must be removed first, and then the built-in manipulator of the polishing equipment must be used to re-clamp and position it. This repeated loading and unloading process greatly delays the overall progress of the polishing operation, resulting in a significant decrease in work efficiency. In addition, after the polishing of the brake disc body 2 is completed, in order to avoid the uneven surface, it is usually necessary to manually evaluate the surface flatness of the brake disc body 2 through visual inspection. This practice not only increases the labor intensity of the staff, but also correspondingly increases the problem of labor costs.

The servo motor 15 can drive the mounting table 12 to rotate, so that the clamping assembly drives the brake disc body 2 to rotate, which is convenient for the brake disc body 2 to fully contact and grind with the polishing belt 1. The stepper motor 2 14 provided on the bracket 11 drives the support shaft 13 to rotate, so that the mounting table 12 can drive the clamping assembly to flip, and then cooperate with the cylinder 10, so that during the grinding process, the brake disc body 2 can be away from the polishing belt 1, complete the flipping action, and then approach the polishing belt 1, thereby realizing the grinding of both sides of the brake disc body 2, avoiding the repeated loading and unloading process, and improving the grinding efficiency.

[0049] In this embodiment, by setting a dust cover 26 between the rotating disk 16 and the chuck 24, it is effectively avoided that the waste chips generated by grinding during the grinding process of the brake disc body 2 will cause pollution to parts such as the gear 1 21 and the gear ring 22, thereby reducing the difficulty of subsequent maintenance of the equipment by the staff.

[0050] Working principle: the unpolished brake disc body 2 is transported to the conveyor belt 3 through the feed conveyor belt 4, and the unpolished brake disc body 2 on the feed conveyor belt 4 is clamped and transported to the polishing belt 1 through the conveyor belt 3 and the robot. After that, the brake disc body 2 continues to move along the polishing belt 1. During this process, the robot can drive the brake disc body 2 to rotate and flip, so that the polishing belt 1 can polish both sides of the brake disc body 2. When the robot moves the polished brake disc body 2 to the top of the transfer component, the robot puts down the brake disc body 2, and the transfer component cooperates with the data acquisition component and the flipping component to realize the detection of both sides of the polished brake disc body 2 in the process of transferring the brake disc body 2 to the discharge conveyor belt 5. , which is convenient for the staff to remove the brake disc body 2 with uneven surface after grinding. Finally, the brake disc body 2 is removed through the discharge conveyor belt 5. The stepper motor 17 arranged on the support arm 6 can drive the support shaft 9 to rotate, so that the support arm 28 can drive the bracket 11 and the clamping assembly on the mounting table 12 to rotate, so that the clamping assembly cooperates with the cylinder 10 to clamp and fix the brake disc body 2 on the feed conveyor belt 4 and then rotate 90° to correspond to the polishing belt 1 to complete the subsequent grinding process. The servo motor 15 can drive the mounting table 12 to rotate, so that the clamping assembly drives the brake disc body 2 to rotate, which is convenient for the brake disc body 2 to fully contact and grind with the polishing belt 1. The stepper motor 2 14 arranged on the bracket 11 drives the support shaft 2 13 to rotate. The mounting table 12 can drive the clamping assembly to flip, and then cooperate with the cylinder 10, so that the brake disc body 2 can be away from the polishing belt 1 during the grinding process, complete the flipping action and then approach the polishing belt 1, thereby achieving the grinding of both sides of the brake disc body 2, avoiding the repeated loading and unloading process, and improving the grinding efficiency. When the brake disc is clamped and fixed, the servo motor 19 drives the gear 21 on the rotating shaft 20 to rotate, so that the gear ring 22 and the rotating connecting ring 23 rotate accordingly, and then the chuck 24 rotates, and the claw 25 contracts under the guidance of the guide rod 18 to complete the clamping and fixing of the brake disc body 2. When the grinding is completed and unloading is required, the servo motor 19 is controlled to reverse, so that the claw 25 is relaxed, which is convenient for the brake disc body 2 after grinding. It falls from the chuck 24, and the gear 2 36 on the transmission roller 1 30 is driven to rotate by the belt 1 32, so that the transmission roller 1 30 on the mounting plate 27 rotates accordingly, so that the polished brake disc body 2 can move to the side of the discharge conveyor belt 5 after falling onto the transmission roller 1 30. There is a gap between each two opposing transmission rollers 1 30, and this gap is larger than the diameter of the flange protrusion on the brake disc body 2. After the two groups of data acquisition components have respectively collected the images of the two sides of the polished brake disc body 2, it is determined that the surface of the brake disc body 2 passing through the transfer component is uneven, that is, the polished brake disc body 2 is unqualified. At this time, the cylinder 2 31 is started, and the support plate 33 is driven away from the mounting plate 27 by the cylinder 2 31.And make the driving rollers 2 34 on the two mounting plates 27 move in the opposite direction, so that the unqualified brake disc body 2 falls from the driving roller 2 34 and will no longer move to the discharging conveyor belt 5. When the data acquisition component determines that it is qualified, the brake disc body 2 can move directly to the next stage. Through this structure, the brake disc body 2 with uneven surface after grinding can be directly discharged, so as to avoid the unqualified brake disc body 2 from moving to the discharging conveyor belt 5 and causing confusion with the qualified brake disc body 2. By arranging a high-definition camera 29 above the mounting plate 27, the image of the brake disc body 2 on the transfer component can be collected, so as to facilitate automatic analysis of the quality of the brake disc body 2. The flatness of the surface of the brake disc body 2 after grinding reduces the tedious process of manual visual inspection. When the brake disc body 2 after grinding passes through the first transfer component and the first data acquisition component and is judged to be qualified, it moves between the mounting frame 1 40 and the mounting frame 2 41, and the servo motor 3 47 on the fixed disc 38 stops. At the same time, the cylinder 3 43 starts and drives the pressure plate 44 to move downward to press and fix the top of the brake disc body 2. After pressing, the electromagnet 49 is energized, so that a repulsive force is generated between the electromagnet 49 and the permanent magnet 51, so that the permanent magnet 51 drives the positioning rod 52 to slide to the cross on the clamping shaft 2 56 while stretching the spring 50. The servo motor 3 47 drives the rotating sleeve 48 to rotate 180°, so that the permanent magnet 51 drives the positioning rod 52 to rotate 180°, and then the mounting frame 1 40, the mounting frame 2 41 and the brake disc body 2 in the middle rotate 180°. After the flipping is completed, the cylinder 3 43 drives the pressure plate 44 to reset, so that the brake disc body 2 fits with the transmission roller 3 45 on the mounting frame 2 41, and does not fit with the transmission roller 3 45 on the mounting frame 1 40. At this time, the electromagnet 49 is powered off, and the permanent magnet 51 is reset by the pulling force of the spring 50, so that the positioning rod 52 slides back to the cross slot of the card shaft 1 53, completing the The locking of the card shaft 1 53 allows the servo motor 3 47 to drive the gear 3 55 on the card shaft 1 53 to rotate through the positioning rod 52, and then the gear 4 57 rotates accordingly, so that the transmission roller 3 45 on the mounting frame 2 41 drives the overturned brake disc body 2 to move to the second transfer component, so that the second data acquisition component can perform image acquisition and analysis on the overturned brake disc body 2. When the brake disc body 2 passes the analysis of the second data acquisition component, the second overturning component can drive the brake disc body 2 to overturn and reset again, so as to avoid the flange protrusion on the brake disc body 2 being at the bottom and contacting the discharge conveyor belt 5 to cause wear.
