Description

Technical Field

[0001] This utility model relates to the field of positioning and clamping technology, and more specifically, it relates to a positioning tooling for automotive parts. Background Technology

[0002] In existing technologies, the positioning fixtures used for automotive parts can usually only be positioned in a fixed position and lack the ability to rotate and adjust. This means that if the angle or direction of the parts needs to be adjusted during inspection or assembly, the position of the fixture must be manually readjusted. This is not only time-consuming and labor-intensive, but also prone to introducing human error and affecting assembly accuracy.

[0003] In existing tooling, the connection between rotating components and clamping and positioning components is usually relatively fixed, lacking the ability to be quickly installed and disassembled. This means that when changing different models of components, a lot of time needs to be spent disassembling and reinstalling the tooling, affecting production flexibility. Modular management can quickly adjust the production line to adapt to different production needs. Existing tooling is difficult to adjust quickly, which limits the flexibility of the production system. Modular management can achieve resource sharing, reduce equipment idle time, and improve resource utilization. Existing tooling is difficult to replace quickly, resulting in low resource utilization. Modular management can reduce production costs and improve production efficiency. Existing tooling is inconvenient to maintain, which increases production costs. Utility Model Content

[0029] Please see Figures 1-5A positioning fixture for automotive parts includes a base plate 1, a rotation adjustment mechanism, a quick-release and quick-installation mechanism, and an loading and unloading auxiliary mechanism. The rotation adjustment mechanism includes a drive motor 2, a drive gear 3, a driven gear 4, a rotating plate 5, and a mounting plate 6. The drive gear 3 is installed at the output end of the drive motor 2 and meshes with the driven gear 4. The rotating plate 5 is located at the top end of the driven gear 4. The mounting plate 6 is located at the top end of the rotating plate 5 and is connected to the rotating plate 5 via the quick-release and quick-installation mechanism. The quick-release and quick-installation mechanism includes a side plate 7, a fixed plate 8, a retaining tube 9, a retaining rod 10, a retaining groove 11, and a cross lock frame 12. The side plate 7 is installed around the sides of the mounting plate 6. The fixed plate 8 is installed around the rotating plate 5. The retaining tube 9 is fixedly installed at the bottom end of the fixed plate 8. The retaining rod 10 is installed on the side plate 7 and can extend into the retaining tube 9. The cross lock frame 12 is laterally slidably installed on the side wall of the retaining tube 9. The retaining groove 11 is located on the side wall of the retaining rod 10.

[0030] In this embodiment, when the drive motor 2 is started, the active gear 3 at the output end of the motor begins to rotate. The active gear 3 meshes with the driven gear disk 4, driving the driven gear disk 4 to rotate. Since the driven gear disk 4 is connected to the rotating plate and the mounting plate 6, the rotating plate 5 will also rotate. The rotation of the rotating plate 5 drives the mounting plate 6 to rotate, so that its position is adjusted relative to the rotating plate 5. The position and angle of the mounting plate 6 can be precisely adjusted as needed to provide precise positioning for the parts and to quickly connect and disconnect the mounting plate 6 and the rotating plate 5. A side plate 7 is installed on the side of the mounting plate 6. The side plate 7 has a snap-fit ​​rod 10, and the snap-fit ​​tube 9 is fixed on the fixed plate 8. When the mounting plate 6 needs to be connected to the rotating plate 5, the snap-fit ​​rod 10 extends into the snap-fit ​​tube 9 and cooperates with the cross lock frame 12. The cross lock frame 12 slides laterally and enters the snap-fit ​​groove 11 to complete the snap-fit ​​connection. In this way, the mounting plate 6 can be quickly connected to the rotating plate 5 through the cooperation of the snap-fit ​​rod 10 and the snap-fit ​​tube 9. When disassembly is required, the cross lock frame 12 pushes the snap-fit ​​rod 10 away from the snap-fit ​​tube 9 through the action of the clamping bracket 14. The snap-fit ​​rod 10 exits from the snap-fit ​​tube 9, and the cross lock frame 12 exits from the snap-fit ​​groove 11, completing the quick disassembly.

[0031] The loading and unloading auxiliary mechanism includes a rotating frame 13, a clamping frame 14, a top-loading toothed ring 15, a directional ring 16, and a bottom tooth 17. The rotating frame 13 is rotatably mounted on the outer wall of the clamping tube 9. The clamping frame 14 is mounted on the outside of the rotating frame 13 and is slidably connected to the cross lock frame 12. The clamping frame 14 pushes the cross lock frame 12 into or away from the slot 11. The top-loading toothed ring 15 is mounted on the top end of the rotating frame 13. The directional ring 16 is slidably mounted on the outer wall of the clamping tube 9. The bottom tooth 17 is mounted on the bottom end of the directional ring 16 and extends into the top-loading toothed ring 15, so that the rotating frame 13 is stable on the outer wall of the clamping tube 9.

[0032] In this embodiment, the rotating frame 13 is mounted on the outer wall of the clamping tube 9 by limiting rotation. The clamping frame 14 is slidably connected to the rotating frame 13. When it is necessary to push the clamping assembly, the clamping frame 14 is slidably connected to the cross lock frame 12, pushing the cross lock frame 12 into or away from the clamping groove 11 to complete the disassembly or connection action. The top tooth ring 15 and the bottom tooth 17, through cooperation with the directional ring 16, ensure that the rotating frame 13 is stably fixed on the outer wall of the clamping tube 9, avoiding loosening or displacement, thereby ensuring accuracy and stability during the loading and unloading process.

[0033] Please see Figures 1-5 As a supplementary embodiment of a positioning fixture for automotive parts, which is an auxiliary mechanism for rotation adjustment, quick disassembly and assembly, and loading and unloading: A transverse lead screw assembly 18 is installed on the top end of the base plate 1, and a driven gear plate 4 is rotatably mounted on the top end of the transverse lead screw assembly 18. A slide rail 19 is installed on the top end of the mounting plate 6, and a clamping block 20 is slidably installed on the slide rail 19. A push motor 21 is installed on the top end of the mounting plate 6, and the output end of the push motor 21 is connected to one end face of the clamping block 20. Multiple sets of slide rails 19 are provided, and multiple sets of slide rails 19 are arranged radially. Multiple sets of clamping blocks 20 are arranged radially on the slide rails 19. A connecting plate 22 is installed on the bottom end of the side wall of the clamping tube 9, and the connecting plate 22 is fixedly installed on the bottom end of the fixing plate 8. A rubber pad 23 is installed on the side wall of the clamping tube 9, and the side wall of the clamping rod 10 presses against the rubber pad 23.

[0034] More specifically, a transverse lead screw assembly 18 is installed on the top of the base plate 1, and the driven gear plate 4 is supported and rotated by the transverse lead screw assembly 18. This allows the driven gear plate 4 to smoothly adjust its position during operation. After the drive motor 2 starts, the rotation adjustment mechanism drives the rotation plate 5 and the mounting plate 6 to rotate through the meshing of the active gear 3 with the driven gear plate 4, adjusting the angle and position of the mounting plate 6. After the mounting plate 6 rotates, it is quickly connected to the rotating plate 5 through the quick-release and quick-install mechanism to complete precise positioning. When the assembly work is completed, the loading and unloading auxiliary mechanism starts to work. The rotating frame 13, the clamping frame 14, and the top-loaded gear ring 15 cooperate to quickly disassemble or reconnect various components by pushing the clamping frame 14 and the cross lock frame 12. The rotating frame 13 is stably fixed on the outer wall of the clamping tube 9 to ensure the safety and stability of the loading and unloading process. The quick-release and quick-install mechanism and the loading and unloading auxiliary mechanism facilitate the quick installation and disassembly of the clamping positioning component and the transverse lead screw assembly 18, and facilitate the modular management of the device.

[0035] In summary, during the use or operation of the overall equipment: when the rotation adjustment mechanism is required, rotation adjustment is performed to ensure the positioning of the components. When the drive motor 2 is started, the active gear 3 at the motor output end begins to rotate. The active gear 3 meshes with the driven gear disk 4, driving the driven gear disk 4 to rotate. Since the driven gear disk 4 is connected to the rotating plate and the mounting plate 6, the rotating plate 5 will also rotate accordingly. The rotation of the rotating plate 5 drives the mounting plate 6 to rotate, adjusting its position relative to the rotating plate 5. The position and angle of the mounting plate 6 can be precisely adjusted as needed to provide accurate positioning for the components.

[0036] When the quick-release mechanism is needed, the mounting plate 6 and the rotating plate 5 can be quickly connected and disassembled. A side plate 7 is installed on the side of the mounting plate 6, and a snap-fit ​​rod 10 is on the side plate 7. The snap-fit ​​tube 9 is fixed on the fixed plate 8. When the mounting plate 6 needs to be connected to the rotating plate 5, the snap-fit ​​rod 10 extends into the snap-fit ​​tube 9 and cooperates with the cross lock frame 12. The cross lock frame 12 slides laterally and enters the slot 11 to complete the snap-fit ​​connection. In this way, the mounting plate 6 can be quickly connected to the rotating plate 5 through the cooperation of the snap-fit ​​rod 10 and the snap-fit ​​tube 9. When disassembly is required, the cross lock frame 12 pushes the snap-fit ​​rod 10 away from the snap-fit ​​tube 9 through the action of the clamping frame 14. The snap-fit ​​rod 10 exits from the snap-fit ​​tube 9, and the cross lock frame 12 exits from the slot 11, completing the quick disassembly.

[0037] When the auxiliary loading and unloading mechanism is required to operate, the rotating frame 13 is mounted on the outer wall of the clamping tube 9 by limiting rotation. The clamping frame 14 is slidably connected to the rotating frame 13. When the clamping assembly needs to be pushed, the clamping frame 14 is slidably connected to the cross lock frame 12, pushing the cross lock frame 12 into or away from the clamping groove 11 to complete the disassembly or connection action. The top tooth ring 15 and the bottom tooth 17, through cooperation with the directional ring 16, ensure that the rotating frame 13 is stably fixed on the outer wall of the clamping tube 9 to avoid loosening or displacement, thereby ensuring accuracy and stability during the loading and unloading process.

[0038] A transverse lead screw assembly 18 is installed on the top of the base plate 1, and the driven gear plate 4 is supported and rotated by the transverse lead screw assembly 18. This allows the driven gear plate 4 to adjust its position smoothly during operation. After the drive motor 2 starts, the rotation adjustment mechanism drives the rotation plate 5 and the mounting plate 6 to rotate through the meshing of the driving gear 3 and the driven gear plate 4, adjusting the angle and position of the mounting plate 6. After the mounting plate 6 rotates, it is quickly connected to the rotating plate 5 through the quick-release and quick-install mechanism to complete precise positioning. When the assembly work is completed, the loading and unloading auxiliary mechanism starts to work. The rotating frame 13, the clamping frame 14, and the top-loaded gear ring 15 cooperate to quickly disassemble or reconnect the various components by pushing the clamping frame 14 and the cross lock frame 12. The rotating frame 13 is stably fixed on the outer wall of the clamping tube 9 to ensure the safety and stability of the loading and unloading process. The quick-release and quick-install mechanism and the loading and unloading auxiliary mechanism facilitate the quick installation and disassembly of the clamping positioning component and the transverse lead screw assembly 18, and facilitate the modular management of the device.

[0039] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
