Description

Technical Field

[0001] This utility model belongs to the field of bridge shell thermoforming, and specifically relates to a material ejection mechanism for bridge shell thermoforming. Background Technology

[0002] A material removal mechanism for thermoforming axle housings is defined as an automated auxiliary device specifically designed for automotive drive axle housings. Its core function is to smoothly and safely detach and transfer the formed axle housing workpiece from the processing mold, equipment workbench, or forming station after the thermoforming process is completed, so as to realize the connection of subsequent processes. At the same time, it avoids the safety risks caused by manual operation of high-temperature workpieces and improves the automation level and processing efficiency of the axle housing thermoforming production line.

[0003] Most existing bridge housing thermoforming equipment cannot unload materials, which becomes a core bottleneck in the production process. First, the high-temperature bridge housing workpieces after thermoforming cannot automatically detach from the mold or workstation, requiring manual intervention for handling. However, the temperature of the workpieces after thermoforming is usually several hundred degrees Celsius, making manual operation not only extremely inefficient but also prone to causing burns and other safety accidents. Second, the workpiece remaining in the mold will prevent subsequent forming processes from proceeding continuously, severely disrupting the production line rhythm, significantly reducing overall processing efficiency, and making it difficult to meet the needs of mass production of bridge housings. Third, the high-temperature workpiece remaining in the mold for a long time may cause quality defects such as deformation and cracking due to uneven heat distribution. At the same time, it will also cause overheating damage to the mold, shortening the mold's service life, increasing equipment maintenance costs and product defect rates, ultimately affecting production efficiency and product quality. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a material ejection mechanism for the thermoforming process of bridge housing, so as to solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A material ejection mechanism for thermoforming a bridge housing includes a mounting base. A central column is rotatably connected to the upper end of the mounting base. A telescopic assembly is slidably connected to the outer side of the upper end of the central column. A clamping assembly is fixedly connected to the lower end of the telescopic assembly. The clamping assembly includes a clamping seat disposed at the lower end of the telescopic assembly. Synchronous pulleys are rotatably connected to both sides of the upper end of the clamping seat. The outer surfaces of the synchronous pulleys are connected via a synchronous belt drive. A synchronous motor is fixedly connected to the upper end of the clamping seat and is fixedly connected to the synchronous pulleys. Clamping grooves are formed on both sides of the lower end of the clamping seat. Clamping screws are rotatably connected to both sides of the interior of each clamping groove. Threaded parts are threaded onto the outer surfaces of the clamping screws. A clamping block is fixedly connected to the other end of each threaded part. A driven bevel gear is fixedly connected to the other end of each clamping screw. A driving bevel gear is rotatably connected to the interior of the clamping groove. The driving bevel gear and the driven bevel gear mesh with each other.

[0007] As a preferred technical solution, a driven gear is rotatably connected to the upper end of the mounting base, the upper end of the driven gear is fixedly connected to the central column, a driving gear is rotatably connected to the upper end of the mounting base, the driving gear meshes with the driven gear, and a rotating motor is fixedly connected to the upper end of the mounting base, the rotating motor is fixedly connected to the driving gear.

[0008] As a preferred technical solution, a movable groove is provided on the outer side of the central column, a movable block is slidably connected inside the movable groove, an electric push rod is fixedly connected to the upper end of the central column, and the other end of the electric push rod passes through the central column and is fixedly connected to the movable block.

[0009] As a preferred technical solution, the telescopic component includes a fixed rod on one side of the movable block, a movable rod threadedly connected to the other end of the fixed rod, an adjusting screw rotatably connected to the other end of the fixed rod, an adjusting screw hole at one end of the movable rod, the adjusting screw being threadedly connected to the adjusting screw hole, and a telescopic motor fixedly connected to the other side of the movable block, the output shaft of the telescopic motor being fixedly connected to the adjusting screw.

[0010] As a preferred technical solution, the movable block and the movable groove are slidably connected to each other, and limit sliders are fixedly connected to both sides of the movable block. A limit groove is formed inside the movable groove, and the limit groove and the limit slider are slidably connected to each other.

[0011] As a preferred technical solution, the fixed rod and the movable rod are slidably inserted into each other, the other end of the fixed rod is fixedly connected to a guide rod, and one end of the movable rod is provided with a guide hole, the guide rod and the guide hole are slidably inserted into each other.

[0012] As a preferred technical solution, the upper end of the mounting base is provided with hidden grooves on both sides, and a fixing through hole is provided inside the hidden groove. A fixing screw is inserted into the fixing through hole and is threaded through the fixing through hole to the base layer.

[0013] In summary, the present invention has the following main advantages:

[0014] First, through the transmission of the synchronous pulley and synchronous belt, the active bevel gears in the clamping slots on both sides of the clamping seat rotate synchronously. The active bevel gears mesh with the driven bevel gear at one end of the clamping screw, thereby driving the clamping screw to rotate. Since the threaded part is threadedly connected to the clamping screw and cannot rotate due to the limitation of the clamping slot, when the screw rotates, it will drive the threaded part and the connected clamping block to move horizontally along the clamping slot, so that the clamping blocks on both sides move closer or further away synchronously, thus completing the clamping of the axle housing workpiece. Mechanical clamping is achieved through the transmission of bevel gears and screws. The clamping force is stable and controllable, which can firmly fix the high temperature and heavy axle housing workpiece, preventing it from slipping and causing safety accidents during transportation. The structure of the clamping block moving along the clamping slot can be adapted to axle housings of different sizes, with strong versatility. Moreover, the limitation of the clamping slot on the threaded part can prevent the parts from loosening due to high temperature, improving the stability and life of the components in the high temperature environment of thermoforming. At the same time, mechanical clamping replaces manual labor, reducing the safety risks of high temperature operation and improving the efficiency of axle housing transfer and processing.

[0015] Secondly, the telescopic motor serves as the power source, with its output shaft directly driving the adjusting screw to rotate. Since the adjusting screw is threadedly connected to the adjusting screw hole at one end of the movable rod, and the fixed rod and movable rod form a nested fit structure, when the adjusting screw rotates, the movable rod will extend and retract along the axial direction of the fixed rod, thereby driving the component connected to the end of the movable rod to complete the distance adjustment. The threaded transmission structure provides high adjustment precision and accurate control of the extension and retraction amount, adapting to the docking requirements of different height positions during the thermoforming process of the bridge housing. The threaded connection has a self-locking characteristic; after extension and retraction, it maintains a stable state without the need for additional locking devices, ensuring that the high-temperature bridge housing will not shift due to external forces or vibrations during clamping and handling, thus improving operational safety.

[0021] Example

[0022] refer to Figures 1 to 4 This embodiment of a bridge housing thermoforming ejection mechanism includes a mounting base 1. A central column 2 is rotatably connected to the upper end of the mounting base 1. A telescopic component 3 is slidably connected to the outer side of the upper end of the central column 2. A clamping component 4 is fixedly connected to the lower end of the telescopic component 3. The clamping component 4 includes a clamping seat 41 disposed at the lower end of the telescopic component 3. Synchronous pulleys 42 are rotatably connected to both sides of the upper end of the clamping seat 41. The outer surfaces of the synchronous pulleys 42 are connected via a synchronous belt 43. A synchronous motor 44 is fixedly connected to the upper end of the clamping seat 41. The synchronous motor 44 is fixedly connected to the synchronous pulleys 42. Clamping grooves 45 are provided on both sides of the lower end of the clamping seat 41. Both sides of the clamping groove 45 are rotatably connected to clamping screws 46. The outer surfaces of the clamping screws 46 are threaded with threaded parts 47. The other end of the threaded parts 47 is fixedly connected to a clamping block 48. The other end of the clamping screws 46 is fixedly connected to a driven bevel gear 49. The inside of the clamping groove 45 is rotatably connected to a driving bevel gear 50. The driving bevel gear 50 and the driven bevel gear 49 are meshed with each other. Both sides of the upper end of the mounting base 1 are provided with hidden grooves 13. The inside of the hidden grooves 13 is provided with fixed through holes 14. Fixed screws 15 are inserted into the fixed through holes 14 and are threadedly connected to the base layer through the fixed through holes 14.

[0023] refer to Figure 1A driven gear 5 is rotatably connected to the upper end of the mounting base 1. The upper end of the driven gear 5 is fixedly connected to the central column 2. A driving gear 6 is rotatably connected to the upper end of the mounting base 1. The driving gear 6 meshes with the driven gear 5. A rotary motor 7 is fixedly connected to the upper end of the mounting base 1. The rotary motor 7 is fixedly connected to the driving gear 6. The rotary motor 7 is a power source. Its output shaft directly drives the driving gear 6 to rotate. Since the driving gear 6 and the driven gear 5 mesh with each other, the rotation of the driving gear 6 will drive the driven gear 5 to rotate synchronously. Since the upper end of the driven gear 5 is fixedly connected to the central column 2, the rotation of the driven gear 5 will directly drive the central column 2 to rotate accordingly. Finally, the central column 2 and the components connected to the central column 2 will rotate around the axis of the central column 2.

[0024] refer to Figure 1 A movable groove 8 is provided on the outer side of the central column 2. A movable block 9 is slidably connected inside the movable groove 8. An electric push rod 10 is fixedly connected to the upper end of the central column 2. The other end of the electric push rod 10 passes through the central column 2 and is fixedly connected to the movable block 9. The electric push rod 10 is the power source. Its telescopic end is fixedly connected to the movable block 9. The movable block 9 is limited to sliding along the groove direction within the movable groove 8 on the outer side of the central column 2. When the electric push rod 10 is started and performs telescopic action, it will directly drive the movable block 9 to slide up and down in the movable groove 8, thereby realizing the smooth lifting and lowering of the component connected to the movable block 9 along the height direction of the central column 2, and accurately adjusting its vertical position to adapt to different operating requirements.

[0025] refer to Figures 1-3 The telescopic assembly 3 includes a fixed rod 31 on one side of the movable block 9, a movable rod 33 threadedly connected to the other end of the fixed rod 31, and an adjusting screw 32 rotatably connected to the other end of the fixed rod 31. An adjusting screw hole 34 is provided at one end of the movable rod 33, and the adjusting screw 32 is threadedly connected to the adjusting screw hole 34. A telescopic motor 35 is fixedly connected to the other side of the movable block 9, and the output shaft of the telescopic motor 35 is fixedly connected to the adjusting screw 32. The telescopic motor 35 is a power source, and its output shaft directly drives the adjusting screw 32 to rotate. Since the adjusting screw 32 is threadedly connected to the adjusting screw hole 34 at one end of the movable rod 33, and the fixed rod 31 and the movable rod 33 form a nested fit structure, when the adjusting screw 32 rotates, the movable rod 33 will move telescopically along the axial direction of the fixed rod 31, thereby driving the component connected to the end of the movable rod 33 to complete the distance adjustment.

[0026] refer to Figure 1 The movable block 9 and the movable groove 8 are slidably connected to each other. Limiting sliders 12 are fixedly connected to both sides of the movable block 9. The movable groove 8 has a limiting groove 11 inside. The limiting groove 11 and the limiting slider 12 are slidably connected to each other. The limiting groove 11 and the limiting slider 12 can limit the movable block 9 during use, so that the movable block 9 slides more stably during use.

[0027] refer to Figure 2 The fixed rod 31 and the movable rod 33 are slidably inserted into each other. The other end of the fixed rod 31 is fixedly connected to a guide rod 16. One end of the movable rod 33 is provided with a guide hole 17. The guide rod 16 and the guide hole 17 are slidably inserted into each other. The guide rod 16 and the guide hole 17 can limit the movable rod 33 during use, thereby preventing the movable rod 33 from rotating.

[0028] Operating principle and advantages: During use, the device is installed on the worktable surface of the molding equipment. After the molding equipment finishes processing, the bridge housing is pushed out of the molding mold. At this time, the electric push rod 10 serves as the power source, and its telescopic end is fixedly connected to the moving block 9. The moving block 9 is restricted to sliding up and down along the groove direction within the moving groove 8 outside the central column 2. When the moving block 9 moves to the uppermost position, the telescopic motor 35 serves as the power source, and its output shaft directly drives the adjusting screw 32 to rotate. Since the adjusting screw 32 is threadedly connected to the adjusting screw hole 34 at one end of the movable rod 33, and the fixed rod 31 and the movable rod 33 form a nested fit structure, when the adjusting screw 32 rotates, the movable rod 33 will telescopically move along the axial direction of the fixed rod 31, thereby driving the component connected to the end of the movable rod 33 to complete the distance adjustment. At this time, the clamping assembly 4 is located at the upper end of the bridge housing. Then, the moving block 9 is moved downwards so that the bridge housing is located inside the clamping block 48. Then, through the transmission of the synchronous pulley 42 and the synchronous belt 43, the clamping seats 41 are driven to clamp on both sides. The active bevel gear 50 in the slot 45 rotates synchronously. The active bevel gear 50 meshes with the driven bevel gear 49 at one end of the clamping screw 46, thereby driving the clamping screw 46 to rotate. Since the threaded part 47 is threadedly connected to the clamping screw 46 and cannot rotate due to the limitation of the clamping slot 45, when the screw rotates, it will drive the threaded part 47 and the connected clamping block 48 to move horizontally along the clamping slot 45, so that the clamping blocks 48 on both sides move closer or further away synchronously, thus completing the clamping of the bridge housing workpiece. Finally, after the clamping is completed, the clamping assembly 4 moves upward and the telescopic assembly 3 resets. Then, the motor 7 is rotated as the power source, and its output shaft directly drives the active gear 6 to rotate. Since the active gear 6 and the driven gear 5 mesh with each other, the rotation of the active gear 6 will drive the driven gear 5 to rotate synchronously. The upper end of the driven gear 5 is fixedly connected to the central column 2. Therefore, the rotation of the driven gear 5 will directly drive the central column 2 to rotate accordingly, thus realizing the rotation of the central column 2 and the components connected to the central column 2 around the axis of the central column 2, thereby achieving the effect of unloading the workpiece.
