[0002] The engine mount is a core component connecting the engine to the chassis / body. Its main function is to fix the engine position and buffer the vibration and impact generated when the engine is running, so as to prevent the vibration from being transmitted to the body and affecting the driving experience. Its working principle is to provide structural support through a metal frame to ensure the stability of the engine installation, and then use rubber / hydraulic damping elements to absorb vibration energy, thus balancing the dual needs of "fixing" and "vibration reduction".

[0003] Engine mounts require gear hobbing during manufacturing. Existing gear hobbing devices mainly use electric gear hobbing cutters to hob the surface of the engine mount, which can hob the required involute tooth profile.

[0010] Preferably, multiple partition plates are fixedly connected inside the guide plate; the ends of the partition plates are inclined; by adding partition plates, the debris inside the collection box can be guided, so that the debris moves to both sides after entering the collection box, thereby reducing the accumulation under the guide plate.

The support body 17 is pressed and fixed. After fixing, the machining seat 13 is started, which drives the support body 17 to approach the hobbing cutter 12. During the approach, the hobbing cutter 12 and the machining table 18 are powered and rotated. Then, when the support body 17 comes into contact with the rotating hobbing cutter 12, it will be machined by the hobbing cutter 12, thereby performing hobbing machining on the surface of the support body 17. The above steps are all mature existing technologies. The debris generated during machining will fall onto the surface of the machining table 18. At this time, the rotation of the machining table 18 will drive... The surface debris moves clockwise and comes into contact with the scraper 19. The scraper 19 intercepts the debris and guides it towards the guide plate 101. Finally, the debris slides down the guide plate 101 into the collection box 102 for collection. By adding the scraper 19, the debris can be guided by the scraper 19 when the processing table 18 drives the support body 17 to rotate, so that the debris can be intercepted and collected during processing.

[0021] like Figures 1 to 2 As shown, a nozzle 2 is fixedly connected to the bottom of the fixing block 14; the nozzle 2 is inclined; an air guide pipe 21 is fixedly connected to the top of the fixing block 14; the nozzle 2 and the air guide pipe 21 are connected; during operation, some debris will adhere to the surface of the support body 17 during processing. At this time, the air guide pipe 21 is connected to an air pump, and the gas is transmitted from the air guide pipe 21 to the nozzle 2 for spraying. The airflow is controlled to make the force of the airflow moderate. After cleaning the debris from the support body 17, the thrust of the airflow disappears, thereby reducing the impact on the debris on the processing table 18 below. By adding the nozzle 2, the surface of the support body 17 can be cleaned during processing, reducing the debris adhering to the surface after processing. This makes it more convenient to observe after processing, thereby increasing the visual effect of the support body 17.

[0022] like Figures 3 to 4 As shown, a slider 3 is slidably connected to the top of the scraper 19; a cleaning plate 31 is rotatably connected to the end of the slider 3; the slider 3 and the cleaning plate 31 are connected by a torsion spring; during operation, after the scraper 19 cleans the debris on the surface of the processing table 18, some debris will remain on the side wall of the scraper 19. At this time, the slider 3 is first slid to the end of the scraper 19 near the processing table 18, and then the cleaning plate 31 is rotated so that the cleaning plate 31 and the side wall of the scraper 19 are in contact. Then the cleaning plate 31 is slid along the surface of the scraper 19. When sliding, the cleaning plate 31 will push the debris on the side wall of the scraper 19 away from the surface of the scraper 19, thereby cleaning it. After the cleaning plate 31 is released, the torsion spring will drive the cleaning plate 31 to return to its original position, thereby removing it from the side wall of the scraper 19; by adding the cleaning plate 31, the side wall of the scraper 19 can be cleaned, thereby reducing the debris attached to the side wall of the scraper 19.

[0023] like Figures 1 to 5 As shown, multiple partition plates 4 are fixedly connected inside the guide plate 101; the ends of the partition plates 4 are inclined; during operation, when debris enters the collection box 102, it will contact the partition plates 4, at which time the partition plates 4 will separate the debris, and after separation, it will move to both sides, thus entering the position between a pair of partition plates 4; by adding partition plates 4, the debris inside the collection box 102 can be guided, so that the debris moves to both sides after entering the collection box 102, thereby reducing the accumulation below the guide plate 101.

[0024] like Figures 1 to 3 As shown, a baffle 5 is fixedly connected to the side wall of the processing seat 13; the baffle 5 and the collection box 102 are correspondingly arranged; during operation, when placing the collection box 102, the end of the collection box 102 can be directly contacted with the baffle 5, and after contact, the middle of the collection box 102 will be exactly located at the unloading point of the guide plate 101, thereby quickly determining the placement position of the collection box 102; by adding the baffle 5, the position of the collection box 102 can be quickly positioned when installing the collection box 102, thereby speeding up the placement of the collection box 102.

[0025] like Figures 3 to 4 As shown, a scraper plate 6 is fixedly connected to the side wall of the cleaning plate 31; the end of the scraper plate 6 is set with an inclined surface; during operation, when the cleaning plate 31 cleans the scraper plate 19, the scraper plate 6 will move along the surface of the scraper plate 19. At this time, the scraper plate 6 will scoop up the attached debris, thereby accelerating the removal of debris from the surface of the scraper plate 19; by increasing the usable end of the scraper plate 6 to quickly push the debris away from the surface of the scraper plate 19, the cleaning of the scraper plate 19 is accelerated.

[0026] Working principle: When machining the support body 17, the support body 17 is first placed in the middle of the machining table 18. Then, the cylinder 15 is activated to drive the disc 16 to contact the top of the support body 17. Upon contact, the support body 17 is pressed and fixed. After fixing, the machining seat 13 is activated to move the support body 17 closer to the hobbing cutter 12. During this approach, the hobbing cutter 12 and the machining table 18 are powered and rotated. When the support body 17 contacts the rotating hobbing cutter 12, it is machined by the hobbing cutter 12, thus performing hobbing machining on the surface of the support body 17. The above steps are all mature existing technologies. The generated debris falls onto the surface of the processing table 18. As the processing table 18 rotates, it causes the debris to move clockwise. After moving, the debris comes into contact with the scraper 19, which intercepts it and guides it towards the guide plate 101. Finally, the debris slides down the guide plate 101 into the collection box 102 for collection. During the processing of the bracket body 17, some debris adheres to its surface. At this time, the air pipe 21 is connected to an air pump, and gas is transmitted from the air pipe 21 to the nozzle 2. The airflow is controlled to maintain a moderate force, effectively cleaning the debris from the bracket body 17. The thrust of the flow disappears, thus reducing the impact on the debris on the processing table 18 below. After the scraper 19 cleans the debris from the surface of the processing table 18, some debris will remain on the side wall of the scraper 19. At this time, first slide the slider 3 to the end of the scraper 19 near the processing table 18, then rotate the cleaning plate 31 so that the cleaning plate 31 and the side wall of the scraper 19 are in contact. Then slide the cleaning plate 31 along the surface of the scraper 19. When sliding, the cleaning plate 31 will push the debris on the side wall of the scraper 19 away from the surface of the scraper 19, thus cleaning it. After releasing the cleaning plate 31, the torsion spring will drive the cleaning plate 31 to return to its original position, thus separating it from the scraper. 19 Sidewalls; When debris enters the collection box 102, it will contact the partition plate 4. At this time, the partition plate 4 will separate the debris. After separation, it will move to both sides and thus enter the position between a pair of partition plates 4. When placing the collection box 102, the end of the collection box 102 can be directly contacted with the baffle 5. After contact, the middle of the collection box 102 will be exactly located at the feeding point of the guide plate 101, thus quickly determining the placement position of the collection box 102. When the cleaning plate 31 cleans the scraper 19, the shovel 6 will move along the surface of the scraper 19. At this time, the shovel 6 will scoop up the attached debris, thereby accelerating the removal of debris from the surface of the scraper 19.
