Description

Technical Field

[0001] The present application relates to the technical field of piston assembly equipment, and in particular to an automobile piston parts assembly system. Background Art

[0002] At present, as a key component of the automobile brake system, the assembly quality of the piston directly affects the operating safety and service life of the vehicle. With the continuous progress of the automobile manufacturing industry, various companies have become more and more strict in the quality control of pistons and related parts, striving to achieve efficient and accurate production through technological innovation. To this end, many automobile manufacturers have actively introduced automated equipment, especially on the piston assembly line, to improve the overall production capacity and product quality.

[0003] In the assembly process of piston parts, traditional assembly methods mainly include manual assembly and semi-automatic production lines. In the manual assembly mode, workers need to manually insert the spring seat and compression spring into the piston body, and manually fix and rivet them. This method is not only time-consuming and labor-intensive, but also often leads to problems such as component position deviation and insufficient fixing strength due to the uncontrollability of manual operations. In contrast, although the semi-automatic production line reduces manual intervention to a certain extent, workers are still required to perform preliminary positioning of the spring seat and compression spring, and then complete the subsequent fixing steps with simple mechanical assistance. In addition, some manufacturers have also tried to use robots for automatic assembly in order to further improve production efficiency and assembly accuracy. However, these early solutions still failed to completely solve the problem of insufficient repetitive accuracy in the assembly process. Although the assembly systems in these early solutions can partially reduce the need for manual operation, it is difficult to ensure the precise coordination between the various components during repeated assembly.

[0004] The common defect of the above-mentioned traditional methods in the process of assembling piston parts is that it is impossible to ensure the precise alignment between the spring seat and the piston body and the repeated assembly accuracy during each assembly. These problems directly lead to a decrease in the piston assembly yield rate, affecting the performance and reliability of the final product. Summary of the invention

When in use, the second cylinder 92 is started to move the second probe 94 toward the piston body until the second probe 94 moves to a suitable position and the height of the spring seat is accurately measured.

[0068] The use principle of the present application is as follows: when in use, the piston body is placed in the placement groove 21 of the current holding block 2 at the loading station, and then the driving motor 122 realizes the rotation of the placement plate 121 through the cooperation of the gear 123 and the gear ring 124, so that the holding block 2 moves to the first detection mechanism 3. The first cylinder 32 is started, and the first probe 34 is driven to move toward the piston body through the first connecting plate 33 until the first probe 34 moves to a suitable position, and the height of the piston body in the placement groove 21 is measured. If the height value of the piston body is qualified, the driving motor 122 is started, and drives the holding block 2 to move to the first loading mechanism 4; if the height value of the piston body is unqualified, the control module controls the driving motor 122 to stop driving.

[0069] Insert the spring seat into the compression spring, and place the compression spring in the loading slot 431, then start the linear motor 42 to send the loading block 43 to a position close to the first robotic arm 41, and the first robotic arm 41 clamps the compression spring and places it into the piston body.

At this time, the compression spring is clamped in the slot, and the compression spring is precisely limited at multiple angles in the horizontal direction. Then the pressing cylinder 512 is started, and the pressing cylinder 512 drives the first pressure head 513 to move, so that the compression spring is compressed and the spring seat moves downward. At this time, the fixing device 52 is started again, specifically, the fixing cylinder 111 is started, and the fixing cylinder 111 pushes the protrusion 524, so that the moving rod 522 drives the second pressure head 523 to move toward the compression spring until the second pressure head 523 is in contact with the spring seat, so that the position of the spring seat and the compression spring is fixed in the vertical direction. At this time, the spring seat sleeve is arranged on the riveting part.

[0071] The driving motor 122 is started to transport the containing block 2 to the second feeding mechanism 6, and the second mechanical arm 61 cooperates with the vibration plate 62 to put the gasket into the spring seat and sleeve the gasket on the riveted part. The driving motor 122 is started to transport the containing block 2 to the riveting machine 7, and the riveting machine 7 rivets the riveted part to achieve riveting fixation of the spring seat and the piston body.

[0072] The driving motor 122 is started to transport the containing block 2 to the releasing mechanism 8, and the pressing cylinder 82 is started first, and the pressing cylinder 82 drives the pressing head 83 to approach and press the spring seat; then the releasing cylinder 84 is started, and when the driving shaft of the releasing cylinder 84 is retracted, the shifting block 85 abuts against the protrusion 524, thereby driving the protrusion 524 to move toward the releasing cylinder 84, and then the second pressing head 523 is separated from the spring seat, thereby realizing the separation of the fixing device 52; then the pressing cylinder 82 is started again to move the pressing head 83 away from the spring seat.
