Description

Technical Field

[0001] This application relates to the field of bevel gear production and testing technology, and more specifically, to an automated production line for precision machining of bevel gears and its online testing system. Background Technology

[0002] Bevel gears are mechanical components used to transmit power and motion. However, existing bevel gear manufacturing processes lack complete production lines, making it impossible to carry out large-scale automated production. The main parameters of bevel gears include module, number of teeth, basic tooth profile, and pitch circle diameter. When selecting bevel gears, ensuring tooth profile matching is very important to guarantee good meshing. Therefore, after production, precise and thorough testing is required. This testing requires multiple sets of online testing tools for analysis. Online tools can help design and analyze bevel gears and support the calculation of core parameters such as module, pressure angle, and transmission ratio.

[0003] A search revealed an existing patent (publication number: CN115388737B) that discloses a high-efficiency testing device for bevel gear production, comprising a base and a dial indicator. A bracket is welded to the top of the base, located on the right side of a slide. A rotating cylinder is rotatably mounted inside the bracket, and a rotating shaft is rotatably mounted inside the rotating cylinder. Clamping mechanisms are evenly arranged at both ends of the rotating cylinder. A cleaning brush is arranged on the right side of the bracket, and the cleaning brush is divided into two groups. The rotating shaft drives two groups of bevel gears to rotate synchronously. The left group meshes with the driven bevel gear and is detected by the slide, a detection spring, and the dial indicator. Simultaneously, the right group is cleaned synchronously by the cleaning brush. After detection, the rotating cylinder is controlled to rotate, flipping the cleaned bevel gears to the detection position, thus achieving the effect of simultaneously cleaning and detecting bevel gears with high detection efficiency. In the process of developing this application, the inventors discovered the following problems with the existing technology: Existing online testing equipment can only be tested manually step by step. However, during manual testing, the results may have slight deviations due to differences in each person's testing methods and judgment standards. Furthermore, manual testing is also at risk of misjudgment.

When the clamp cylinder 58 is performing clamping work, it drives the telescopic shaft 581 and the drive gear plate 582 connected to it to extend into the clamp connecting block 551. During the telescopic process, it drives the drive gear 542 to rotate. Before completing the processing work or switching work, it is reset. During the reset process, the clamping block of the clamp is reset. The clamp switching work can be completed by driving the rotating connecting block 521 to rotate through the switching motor 52. When switching to clamp 54, clamp 54 completes the clamping action through two sets of symmetrical rotating shaft clamping blocks 541. During the rotation of drive gear 542, it drives center gear 543 to rotate. During the rotation of center gear 543, it drives two sets of clamping block gear plates 544 to move. During the movement of clamping block gear plates 544, it drives the clamping block connecting blocks 545 connected to them to move closer or further away from each other, thereby driving the two sets of rotating shaft clamping blocks 541 to complete the clamping or releasing action. Furthermore, when switching to clamp number 3 56, the drive gear 542 drives the second center gear 565 to rotate during rotation. The second center gear 565 drives the three sets of slider gear plates 563 to slide on the slider slide rod 564 during rotation. During the movement, the slider gear plates 563 drive the shrink connecting block 562 and the annular clamping block 561 connected to it to move through the drive slide groove 5621. During the movement, the three sets of annular clamping blocks 561 move closer or further away from each other and complete clamping or fixing during the movement. During online inspection, the finished bevel gear is placed on the central inspection fixture 67 for fixation. When the bevel gear to be inspected is placed in the central inspection fixture 67, the bevel gear is placed between the outer expansion clamping block 671 and the central inspection fixture 67. The outer expansion cylinder 674 drives the frustum top block 673 to rise. During the rising process, the frustum top block 673 can squeeze the outer expansion clamping block 671 outward. During the squeezing process, the outer expansion clamping block 671 moves in the central inspection fixture 67 through the connecting telescopic rod 672 and clamps the inner wall of the bevel gear to be inspected. The pressure sensor 6711 provides feedback on the clamping action and controls the outer expansion cylinder 674 to stop moving after clamping and fixing. The inner diameter information of the bevel gear to be inspected can be calculated based on the telescopic distance of the outer expansion cylinder 674. During the fixing process, the outer diameter detection ring 66 detects the outer diameter of the finished bevel gear. The detection moving motor 68 drives the first detection lead screw 682 and the second detection lead screw 683 to rotate through the central transmission box 681. The detection moving motor 68 drives the second detection lead screw 683 and the drive worm gear 6811 to rotate. During the rotation of the drive worm gear 6811, the drive worm wheel 6812 is driven to rotate. During the rotation of the drive worm wheel 6812, the first detection lead screw 682 connected to it is driven to rotate. During the rotation of the second detection lead screw 683, the second transmission slider 685 connected to it is driven to move. During the movement of the second transmission slider 685, the second transmission slider 685 drives the connecting drive block 652 and the detection drive device 65 connected to it to move to the position where it meshes with the finished bevel gear. The standard detection bevel gear 651 drives the finished bevel gear to rotate. During the rotation, the end jump detection rod 63 detects the end jump value of the finished bevel gear during rotation. During rotation, the first detection lead screw 682 drives the first transmission slider 684 to move, and the first transmission slider 684 drives the lifting detection connecting block 62 to move through the first transmission slide rod 6841. The lifting block 633 and the end jump detection rod 63 connected to it can be moved to a suitable detection height through the lifting cylinder 634. The rotation drive motor 653 drives the standard detection bevel gear 651 to rotate through the detection drive device 65. During the rotation, the end jump detection rod 63 inserts the end jump test needle 631 into the tooth surface of the bevel gear for detection, and the detection data is fed back to the end jump meter 632.
