Abstract

This invention provides a gear chamber cover end face processing device, including a frame, a conveying mechanism and a mounting frame. A dry ice blaster is slidably mounted on the mounting frame. A drive motor is fixedly mounted on the frame, and a drive shaft is mounted on the output shaft of the drive motor. The drive shaft is connected to the conveying mechanism via a speed-regulating drive unit to convert the rotation of the drive shaft into motion of the conveying mechanism. When the gear chamber cover moves past the bottom of the mounting frame, the drive mechanism decelerates. A reciprocating drive mechanism connected to the speed-regulating drive unit is mounted on the mounting frame. This device not only effectively deburrs the gear chamber cover using the moving dry ice blaster, but also achieves synchronous linkage between conveying speed regulation and blasting processing, eliminating the need for repeated machine start-stop operations. Furthermore, it allows for loading and unloading of materials simultaneously with deburring, significantly reducing the processing time for a single batch of workpieces.

Description

Technical Field

[0001] This invention specifically relates to a gear chamber cover end face machining device. Background Technology

[0002] The gear chamber cover is a housing part of the engine's timing gear mechanism. It is mostly made of cast iron or aluminum alloy and serves to seal and store oil, protect the gears, and house auxiliary parts. Burrs remaining on the sealing surface of the gear chamber cover can easily scratch the seals and cause oil leaks. Debris falling into the gear cavity can also cause gear jamming and wear. Burrs on the outer contour can also affect the fit of the assembly. Therefore, after processing, all burrs on all parts must be completely removed.

[0003] For example, Chinese utility model patent CN223932810U discloses a laser device for deburring and impact strengthening of gear chamber covers. The device includes a PLC control platform, which displays data via a touchscreen. The PLC control platform controls a robotic arm control cabinet, which in turn controls the robotic arm. The robotic arm is connected to a teach pendant and a PC offline system via a built-in cable. This allows for the integration of laser deburring and impact strengthening treatments for gear chamber covers into a single system. It can utilize laser deburring technology to deburr workpieces and, by modifying process parameters, laser impact strengthening technology can be used to perform impact strengthening treatments on key parts of the gear chamber cover components.

[0004] However, the industry currently widely uses dry ice blasting to remove metal burrs from the end face of gear chamber covers. This method has the advantages of no secondary pollution and no damage to the workpiece substrate, but the automation level of existing processing equipment is extremely low. The conventional processing mode requires workers to hoist and place the gear chamber covers one by one at the station of the dedicated deburring equipment, fix the workpiece, start the equipment to complete the deburring, pause the equipment after processing, remove the finished product, and then repeat the loading and unloading of the next workpiece.

[0005] This processing method has significant drawbacks. The entire process relies on manual loading and unloading of workpieces, resulting in a cumbersome operation, high labor intensity, and repeated start-stop cycles for each workpiece loading and unloading, making continuous processing impossible. Frequent start-stop cycles not only shorten equipment lifespan and increase energy consumption but also disrupt processing steps, significantly wasting processing time. This leads to low efficiency in batch deburring of gear chamber covers, making it difficult to meet production demands. Therefore, this paper proposes a gear chamber cover end face processing device to address these issues. Summary of the Invention

[0006] Therefore, it is necessary to provide a gear chamber cover end face processing device to address the current practice of removing metal burrs from the end face of gear chamber covers by spraying dry ice, which mostly involves placing the gear chamber cover on a deburring device for burr removal. This method requires repeated starting and stopping of the equipment and manual loading and unloading of the gear chamber cover by workers, which not only increases the workload of workers but also wastes a lot of time and reduces the efficiency of batch processing.

[0012] In one embodiment, the power transmission mechanism includes: A double-sided gear disc is rotatably mounted at the end of the drive frame and slidably sleeved on the drive shaft. Two sets of single-sided gear disks are arranged at relative intervals and are located on both sides of the double-sided gear disk. The single-sided gear disks are rotatably mounted within the frame, and one set of the single-sided gear disks meshes with one side of the double-sided gear disk; and A drive assembly is disposed on two sets of single-sided toothed discs and connected to one set of conveyor rollers to convert the uniform rotation of the two sets of single-sided toothed discs into driving the rotation of the conveyor rollers.

[0014] In one embodiment, the driving component includes: A first transmission shaft is rotatably mounted within the frame and connected to one of the sets of single-sided gear discs via a first synchronous belt mechanism.

[0017] Compared with the prior art, the present invention has at least the following advantages: This device achieves continuous automated conveying of gear chamber covers via a frame-mounted conveyor mechanism. With the coordination of a drive motor and a speed-regulating drive unit, the conveyor mechanism automatically decelerates as the workpiece passes the processing station, providing ample time for dry ice blasting deburring and ensuring thorough burr removal. Normal conveying can resume after the workpiece leaves the station, reducing conveying time and eliminating the need for overall equipment start-up and shutdown, thus preventing energy consumption and equipment wear caused by frequent starts and stops. Furthermore, the device uses a single drive motor to control the speed regulation of the conveyor mechanism and the reciprocating sliding of the dry ice blaster. This not only allows for thorough deburring of the gear chamber cover through the moving dry ice blaster but also enables synchronized speed regulation of the conveyor and blasting processing. No additional drive equipment is required, resulting in high structural integration and strong operational coordination. It eliminates the need for repeated machine start-ups and shutdowns by operators and allows for loading and unloading simultaneously with deburring, significantly shortening the processing time for a single batch of workpieces and greatly improving the batch processing efficiency of deburring the end face of the gear chamber cover, making it suitable for large-scale industrial production needs.

[0021] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention; therefore, the invention is not limited to the specific embodiments disclosed below.

[0022] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0024] Example: Please see Figures 1 to 3 The present invention provides a gear chamber cover end face processing device, including a frame 1, on which a conveying mechanism and a mounting frame 10 are provided. The conveying mechanism includes two sets of conveying rollers 2 arranged at intervals, which are rotatably arranged at both ends of the frame 1. It also includes two sets of conveyor belts 3, which are respectively sleeved on the two sets of conveying rollers 2 at both ends. A gap is provided between the two sets of conveyor belts 3. Multiple sets of receiving rollers 4 are rotatably arranged on the frame 1, and the multiple sets of receiving rollers 4 abut against the inner top surface of the conveyor belts 3.

[0025] The conveyor belt 3 can be driven to move by controlling the rotation of the conveyor roller 2, so as to transport the gear chamber cover through the conveyor belt 3. Multiple sets of receiving rollers 4 support the conveyor belt 3 to prevent the conveyor belt 3 from deforming due to excessive weight of the gear chamber cover. A dry ice ejector 13 is reciprocatingly mounted on the mounting frame 10. Dry ice particles can be sprayed out by the dry ice ejector 13. When the dry ice particles hit the burrs, they transfer heat from the dry ice particles to the corresponding burrs, thereby generating a significant temperature gradient and corresponding high shear force in the burrs for burr removal.

[0026] Please see Figure 2 , 45, 6. In this embodiment, a drive motor 16 is fixedly mounted on the frame 1. A drive shaft 17 is mounted on the output shaft of the drive motor 16. The drive shaft 17 is connected to the conveying mechanism through a speed-regulating drive unit to convert the rotation of the drive shaft 17 into the movement of the conveying mechanism. When the gear chamber cover moves past the bottom of the mounting frame 10, the drive unit drives the conveying mechanism to decelerate. The speed-regulating drive unit includes a transverse frame 18 that can slide laterally on the frame 1. A control mechanism connected to the transverse frame 18 is mounted on the frame 1. The control mechanism drives the transverse frame 18 to slide when the gear chamber cover passes the mounting frame 10 and drives the transverse frame 18 to reset when the gear chamber cover moves out of the mounting frame 10. The control mechanism includes a lifting plate 6, a mounting base 5 on the frame 1, the lifting plate 6 is movably mounted on the mounting base 5, and a first elastic element 7 is provided between the lifting plate 6 and the mounting base 5. A vertical plate 8 is fixedly mounted on the lifting plate 6, the vertical plate 8 passes through the gap between the two sets of conveyor belts 3, and both ends of the vertical plate 8 are provided with inclined surfaces. A drive column 9 is provided at one end of the lifting plate 6. An inclined groove 19 is opened on the transverse frame 18, and both ends of the inclined groove 19 are connected to straight grooves 20. The drive column 9 is slidably locked in one set of straight grooves 20 and can slide through the inclined groove 19 into the other set of straight grooves 20.

[0027] The continuous rotation of the conveying roller 2 can convey the gear chamber cover. During the conveying process, when the gear chamber cover moves to the bottom of the mounting frame 10, it can abut against the inclined surface of the vertical plate 8 to drive the vertical plate 8 to descend. At the same time, the first elastic element 7 is compressed. During the descent of the vertical plate 8 and the lifting plate 6, the horizontal sliding frame 18 can be driven to slide laterally through the cooperation of the drive column 9 and the inclined groove 19. When the gear chamber cover moves out of the mounting frame 10, the lifting plate 6 is controlled to rise under the action of the first elastic element 7, and the horizontal sliding frame 18 is controlled to reset, so that the gear chamber cover can control the horizontal sliding frame 18 to slide back and forth when passing through the processing station.

[0028] Please see Figures 5 to 7In this embodiment, the speed control drive unit further includes a drive frame 23 that can slide laterally on the frame 1. The drive frame 23 is connected to the transverse frame 18 through a limiting drive mechanism to convert the sliding of the transverse frame 18 into the sliding of the drive frame 23, and to ensure that the drive frame 23 only stops at both ends of its sliding stroke. The limiting drive mechanism includes an intermediate plate 21 disposed on the transverse frame 18, the intermediate plate 21 being located between the drive frames 23, and a second elastic member 25 being disposed between the intermediate plate 21 and the drive frame 23. Both ends of the drive frame 23 are provided with locking blocks 24. A mounting frame 27 is fixedly installed on the frame 1. Two sets of sliding locking frames 28 are arranged between the mounting frames 27. The two sets of locking frames 28 are arranged symmetrically and alternately. One end of the locking frame 28 is provided with a wedge-shaped stop block 29, and the other end is provided with a wedge-shaped opening block 30. A T-shaped unlocking block 22 is provided on the middle plate 21. The stop block 29 on one set of locking frames 28 is locked inside one set of locking blocks 24. The unlocking block 22 abuts against the end face of the opening block 30 on the other set of locking frames 28. A third elastic member 31 is provided between the locking frame 28 and the mounting frame 27.

[0029] During the lateral sliding of the transverse frame 18, the locking block 24 at one end of the drive frame 23 is blocked and limited by one set of stop blocks 29, and cannot slide. Thus, the intermediate plate 21 compresses one set of second elastic members 25. At this time, the unlocking block 22 disengages from the opening block 30 on the other set of locking frames 28 until the unlocking block 22 at the end of the intermediate plate 21 pushes the opening block 30 on the locking frame 28 to cause the locking frame 28 to slide and compress the third elastic member 31. The drive frame 23 is released from fixation and pushed to move laterally under the reset action of the compressed set of second elastic members 25 until another set of locking blocks 24 passes through one side of another set of stop blocks 29 and fixes the position of the drive frame 23 again to control the lateral movement of the drive frame 23. The drive frame 23 only stops at both ends of its sliding stroke.

[0030] Please refer to it again. Figures 5 to 7 In this embodiment, the speed control drive unit further includes a power transmission mechanism disposed on the drive frame 23 and connected to one of the sets of conveying rollers 2. The power transmission mechanism drives the conveying rollers 2 to rotate and decelerate when the drive frame 23 moves to both ends of its stroke. The power transmission mechanism includes a double-sided gear disk 26 rotatably disposed at the end of the drive frame 23. The double-sided gear disk 26 is slidably sleeved on the drive shaft 17. Two sets of single-sided gear disks 33 are rotatably disposed in the frame 1. The two sets of single-sided gear disks 33 are arranged relatively at intervals and are located on both sides of the double-sided gear disk 26. One set of single-sided gear disks 33 meshes with one side of the double-sided gear disk 26.

[0031] When the drive shaft 17 rotates under the control of the drive motor 16, it drives the double-sided gear disk 26 to rotate, thereby controlling the rotation of one set of single-sided gear disks 33. Under the action of the limit drive mechanism, the drive frame 23 stops only at both ends of its sliding stroke to ensure that the double-sided gear disk 26 always maintains engagement with one set of single-sided gear disks 33. The limit drive mechanism prevents the double-sided gear disk 26 from disengaging from both sets of single-sided gear disks 33 at the same time, so as to ensure the stable transmission of power from the drive motor 16.

[0032] Please see Figure 5 , 7 In this embodiment, a rotatable drive disk 32 is provided inside the frame 1, and a mounting post 34 is provided on one side of the single-sided gear disk 33. The mounting post 34 is slidably inserted on the drive disk 32, and a fourth elastic element 35 is provided between the drive disk 32 and the single-sided gear disk 33. The single-sided gear disk 33 can slide slightly along the axis of the mounting post 34 and reset under the action of the fourth elastic element 35. The arrangement of the fourth elastic element 35 can avoid the inability to transmit power when the double-sided gear disk 26 and the single-sided gear disk 33 collide, thereby improving the stability and reliability of the device during operation.

[0033] Please see Figure 2 , 3 5. In this embodiment, the power transmission mechanism further includes a drive assembly disposed on two sets of single-sided gear discs 33 and connected to one set of conveying rollers 2. The drive assembly converts the uniform rotation of the two sets of single-sided gear discs 33 into the rotation of the conveying rollers 2. The drive assembly includes a first transmission shaft 36 and a second transmission shaft 37 rotatably disposed within the frame 1. The first transmission shaft 36 is connected to one set of single-sided gear discs 33 via a first synchronous belt mechanism 38. A first pulley 39 is disposed on the first transmission shaft 36, and a second pulley 14 is disposed on the conveying roller 2. The first pulley 39 and the second pulley 14 are connected via a first transmission belt 41. The diameter of the first pulley 39 is smaller than that of the second pulley 14. The second transmission shaft 37 is connected to one set of single-sided gear discs 33 via another set of first synchronous belt mechanisms 38. A third pulley 40 is disposed on the second transmission shaft 37, and a fourth pulley 15 is disposed on the conveying roller 2. The third pulley 40 and the fourth pulley 15 are connected via a second transmission belt 42. The diameter of the third pulley 40 is larger than that of the fourth pulley 15.

[0034] When the gear chamber cover has not passed the mounting bracket 10, the double-sided gear disc 26 meshes with a set of single-sided gear discs 33 near the second transmission shaft 37, thereby driving the second transmission shaft 37 to rotate via the first synchronous belt mechanism 38. During the rotation of the second transmission shaft 37, the cooperation of the third pulley 40 and the fourth pulley 15 drives the conveyor roller 2 to rotate faster, thereby reducing the conveying time and thus reducing the deburring interval. When the gear chamber cover passes the mounting bracket 10, the double-sided gear disc 26 meshes with a set of single-sided gear discs 33 near the first transmission shaft 36, thereby driving the first transmission shaft 36 to rotate via the first synchronous belt mechanism 38. During the rotation of the first transmission shaft 36, the cooperation of the first pulley 39 and the second pulley 14 drives the conveyor roller 2 to rotate slower, thereby extending the time the gear chamber cover spends passing the mounting bracket 10, providing sufficient working time for dry ice blasting deburring, and ensuring thorough burr removal.

[0035] Please see Figure 2 , 3 In this embodiment, the mounting frame 10 is equipped with a reciprocating drive mechanism connected to the speed-regulating drive unit. This reciprocating drive mechanism converts the power of the drive shaft 17 into power to drive the dry ice injector 13 to slide reciprocally when the conveying mechanism decelerates. It is understood that in some preferred embodiments, the reciprocating drive mechanism is connected to the first transmission shaft 36 to drive the dry ice injector 13 to slide reciprocally when the conveying mechanism decelerates. The reciprocating drive mechanism includes a reciprocating lead screw 12 rotatably mounted on the mounting frame 10. The dry ice injector 13 is equipped with a connecting seat 11, which is slidably mounted on the mounting frame 10. The connecting seat 11 cooperates with the reciprocating lead screw 12, and the reciprocating lead screw 12 is connected to the first transmission shaft 36 via a second synchronous belt mechanism 43.

[0036] As the gear chamber cover rotates through the mounting bracket 10, the first transmission shaft 36 can be driven to rotate by the second synchronous belt mechanism 43, thereby controlling the connecting seat 11 and the dry ice sprayer 13 to slide back and forth at the bottom of the mounting bracket 10, so as to fully deburr the end face of the gear chamber cover and effectively reduce the processing dead angle.

[0037] Specific usage and beneficial effects of the present invention: This device utilizes a conveyor mechanism mounted on a frame 1 to achieve continuous and automated conveying of the gear chamber cover. With the coordination of the drive motor 16 and the speed-regulating drive unit, the conveyor mechanism automatically decelerates as the workpiece passes the processing station, providing ample time for dry ice blasting deburring and ensuring thorough burr removal. Normal conveying can resume after the workpiece leaves the station, reducing conveying time and eliminating the need for overall equipment start-up and shutdown, thus preventing energy consumption and equipment wear caused by frequent starts and stops. Furthermore, the device uses the same drive motor 16 to control the speed regulation of the conveyor mechanism and the reciprocating sliding of the dry ice blaster 13. This not only allows for thorough deburring of the gear chamber cover through the moving dry ice blaster 13 but also enables synchronous linkage between conveying speed regulation and blasting processing. No additional drive equipment is required, resulting in high structural integration and strong operational coordination. It eliminates the need for repeated machine start-ups and shutdowns by operators and allows for loading and unloading simultaneously with deburring, significantly shortening the processing time for a single batch of workpieces and greatly improving the batch processing efficiency of deburring the end face of the gear chamber cover, thus meeting the needs of large-scale industrial production.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
