Description

Technical Field

[0001] This utility model belongs to the field of handbrake technology, and specifically relates to an automatic posture adjustment mechanism for riveting handbrakes. Background Technology

[0002] The NSW-I type handbrake is connected by riveting, with 6 rivet holes surrounding the part. Figure 5 As shown. Traditional handbrake riveting processes rely heavily on the skills and experience of operators for manual positioning and riveting. This method is not only inefficient, but also difficult to guarantee optimal positioning and force for each riveting operation due to the uncertainty of human factors. Therefore, developing a mechanism that can automatically adjust the riveting position is of great significance for improving production efficiency and product quality. This utility model relates to the field of riveting and is an automatic posture adjustment (position adjustment) mechanism for the handbrake riveting process. This mechanism aims to improve riveting accuracy and efficiency, reduce manual intervention, and ensure the consistency and reliability of riveting quality. Utility Model Content

[0003] In order to solve the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a handbrake riveting automatic posture adjustment mechanism to realize the automatic positioning and precise riveting of rivets, thereby replacing the traditional manual operation and improving the automation level of riveting operations and product quality.

[0004] The technical solution adopted in this utility model is as follows:

[0005] An automatic posture adjustment mechanism for riveting a handbrake includes a frame, a large plate fixed on the frame, a Y-axis lead screw assembly mounted on the large plate, a longitudinal movement assembly threadedly connected to the Y-axis lead screw assembly, an X-axis lead screw assembly threadedly connected to the longitudinal movement assembly, a transverse movement assembly threadedly connected to the X-axis lead screw assembly, a lifting cylinder mounted on the transverse movement assembly, a lifting plate connected to the piston rod of the lifting cylinder, a rotating platform mounted on the lifting plate, and a rotating plate for mounting products connected to the output end of the rotating platform; it also includes a CCD component for position detection and interference detection of rivet holes on the product.

[0006] The product is placed on the rotating plate and limited by the positioning pins. The Y-axis lead screw assembly drives the longitudinal movement assembly to move in the Y-axis direction, and the X-axis lead screw assembly drives the transverse movement assembly in the X-axis direction. After reaching the set position, the rotating platform drives the rotating plate to rotate, moving the rivet holes on the product to the vision inspection position. The CCD assembly performs position detection and interference detection on the rivet holes on the product and provides feedback on the position deviation and interference results. If material interference is detected, the system alarms and directly removes the product from the riveting area, prompting manual intervention at the unloading position. If there is a position deviation, the Y-axis and X-axis lead screw assemblies are adjusted for compensation, and the CCD assembly checks again after compensation. When the position and interference feedback are qualified, the lifting cylinder extends to lift the product, and then the Y-axis lead screw assembly sends the product to the riveting position. The lifting cylinder then descends to place the product into the riveting machine.

[0007] This invention uses a CCD component to detect the position and interference of the rivet holes, providing feedback on positional deviations and interference results. Adjustments and compensations are then made through the movements of the Y-axis and X-axis lead screw assemblies. The invention adjusts the product position using the Y-axis and X-axis lead screw assemblies, and, with the cooperation of a rotating platform, completes the riveting of six rivets by rotating the handbrake one revolution.

[0008] This invention ensures that each rivet is accurately installed through precise positioning and force control, greatly improving the assembly quality and consistency of the product. The automated operation process reduces reliance on manual labor, accelerates the production pace, and improves overall work efficiency. This invention reduces the physical burden on operators, improves the working environment, and is conducive to long-term stable production. This invention can adapt to handbrake components of different specifications, possessing a certain degree of versatility and flexibility.

When the Y-axis drive device drives the Y-axis lead screw to rotate, the Y-axis lead screw drives the longitudinal movement component to move longitudinally, thus accurately adjusting the Y-axis displacement of the product.

[0010] In a preferred embodiment of this invention, a Y-axis linear guide rail is mounted on the large plate, and the longitudinal movement component is slidably connected to the Y-axis linear guide rail. The Y-axis linear guide rail guides the longitudinal movement component, ensuring the stability of the longitudinal movement component during movement.

The transverse movement assembly is threadedly connected to the X-axis lead screw. When the X-axis drive device drives the X-axis lead screw to rotate, the X-axis lead screw drives the transverse movement assembly to move longitudinally, thus accurately adjusting the X-axis displacement of the product.

[0014] In a preferred embodiment of this invention, an X-axis linear guide is mounted on the longitudinal moving component, and the transverse moving component is slidably connected to the X-axis linear guide. The X-axis linear guide guides the transverse moving component, ensuring its stability during movement.

[0015] In a preferred embodiment of this invention, an X-axis slotted photoelectric sensor is mounted on the longitudinal movement component, and an X-axis sensor plate is mounted on the transverse movement component. The X-axis slotted photoelectric sensor cooperates with the X-axis sensor plate. The X-axis slotted photoelectric sensor serves to limit movement and provide origin positioning.

[0016] In a preferred embodiment of this utility model, a Y-axis cable chain connects the large plate to the longitudinal movement component, and an X-axis cable chain connects the longitudinal movement component to the transverse movement component. Signal and power cables are housed within the Y-axis and X-axis cable chains, with the cables first passing through the Y-axis cable chain, then through the X-axis cable chain, and finally entering the control panel.

[0033] A Y-axis slotted photoelectric sensor 22 is mounted on the large plate 2, and a Y-axis sensor sensing plate 44 is mounted on the Y-axis guide rail mounting plate 41. The Y-axis slotted photoelectric sensor 22 and the Y-axis sensor sensing plate 44 cooperate with each other. The Y-axis slotted photoelectric sensor 22 serves as a limit and origin positioning device.

[0034] The X-axis lead screw assembly 5 includes an X-axis drive device 51, which is mounted on an X-axis mounting plate 43. An X-axis lead screw 52 is connected to the output end of the X-axis drive device 51, and the other end of the lead screw is rotatably connected to the X-axis mounting plate 43.

[0040] The product is placed on the rotating plate 81 and limited by the positioning pin. The Y-axis lead screw assembly 3 drives the longitudinal movement assembly 4 to move in the Y-axis direction, and the X-axis lead screw assembly 5 drives the transverse movement assembly 6 in the X-axis direction. After reaching the set position, the rotating platform 8 drives the rotating plate 81 to rotate, moving the rivet holes on the product to the visual inspection position.
