Description

Technical Field

[0001] The utility model belongs to the technical field of gear processing, and particularly relates to a gear chamfering device. Background Art

[0002] Gears can transmit power from one gear on one shaft to another gear on another shaft through the meshing of teeth, completing the transmission of different speeds and torques. They are widely used in various mechanical equipment. In the chamfering process of gears, a chamfering machine is usually used. The chamfering machine clamps the gear and places its tooth surface edge under a specific cutting tool, and then rotates the gear to allow the cutting tool to chamfer the gear tooth surface. The cutting tool is usually composed of multiple blades. As the gear rotates, the blade gradually cuts the tooth surface edge to form the required chamfer. In actual processing, the gear is usually placed in the clamping area inside the chamfering machine by manual or mechanical arms. After the chamfering of the gear is completed, it can be removed and replaced with a new gear. However, the staff needs to wait for a long time, which makes the actual working time of the chamfering machine cutting tool short and the working pause interval is long, resulting in low processing efficiency of the equipment.

[0017] In this embodiment: the support shell 1 supports each component of the device, and a motor for driving the drive shaft 11 is arranged inside the support shell 1. The motor drives the drive shaft 11 to rotate, and the drive shaft 11 drives the bevel gear 111 to rotate. The hydraulic telescopic rod 12 supports and drives the rotating pressure plate 121. The hydraulic telescopic rod 12 can drive the rotating pressure plate 121 to descend. The rotating pressure plate 121 and the drive shaft 11 clamp the two ends of the connecting shaft 31, and the connecting shaft 31 supports the gear. The rotating column 2 supports and rotates a plurality of support carriers 3. The rotating column 2 is driven to rotate by the motor inside the supporting shell 1, and the supporting carrier plate 3 can be raised and lowered on the side wall of the rotating column 2. The gear is sleeved on the connecting shaft 31, and the connecting shaft 31 can drive the gear to rotate through the groove on the side. The rotating column 2 drives the gear to rotate above the driving shaft 11 through the supporting carrier plate 3 and the connecting shaft 31, and the output end of the hydraulic telescopic rod 12 is extended. The hydraulic telescopic rod 12 drives the rotating pressure plate 121 to slide downward, and the rotating pressure plate 121 contacts and squeezes the top of the gear, and the gear transmits the squeezing force of the rotating pressure plate 121 to the connecting shaft 31. The gear 111 is engaged with the bevel gear 111 in the conical meshing groove 32, and the driving motor is controlled to drive the driving shaft 11 to rotate, and the driving shaft 11 drives the bevel gear 111 to rotate, and the bevel gear 111 drives the connecting shaft 31 to rotate, and the connecting shaft 31 drives the gear to rotate, and the gear drives the rotating pressure plate 121 to rotate, and the rotation connection relationship between the rotating pressure plate 121 and the hydraulic telescopic rod 12 is utilized, so that the rotation of the gear will not be disturbed by the hydraulic telescopic rod 12, and the rotating gear is chamfered by the cutting tool on the supporting shell 1. At this time, the connecting shaft 31 outside the supporting shell 1 is in a non-working state, so that the staff or the mechanical arm can replace the connecting shaft 31 in the non-working state, and when the next gear is chamfered, it is only necessary to control the rotation of the rotating column 2 to make the next gear reach the processing area for chamfering, so that the actual working time of the chamfering machine cutting tool is increased, and the working pause interval time is reduced, thereby improving the processing efficiency of the equipment.

[0018] The side walls of several connecting shafts 31 are fixedly connected with shielding rings 33, and the shielding rings 33 are rotatably connected to the top of the corresponding supporting plate 3; the shielding rings 33 limit the bottom of the gear so that the gear will not be disturbed by the supporting plate 3 when rotating, and the connecting shaft 31 drives the gear and the shielding ring 33 to rotate synchronously, so that the shielding ring 33 will not generate rotational friction with the gear, thereby avoiding damage to the shielding ring 33 and the gear.

[0019] A plurality of ball bearings 34 are provided on the side wall of the connecting shaft 31, and the plurality of ball bearings 34 are slidably connected to the corresponding inner wall of the supporting plate 3; the supporting plate 3 limits the connecting shaft 31 so that the height of the connecting shaft 31 and the supporting plate 3 are always kept consistent. When the connecting shaft 31 rotates, the connecting shaft 31 drives the plurality of ball bearings 34 to rotate, and the ball bearings 34 reduce the friction resistance and friction loss between the connecting shaft 31 and the supporting plate 3.

[0020] The side wall of the rotating column 2 is provided with a plurality of slide grooves 21, and one end of the plurality of support carriers 3 is fixedly connected with an arc-shaped limit plate 35, and the inner wall of the arc-shaped limit plate 35 is fixedly connected with a limit slider 351, and the limit slider 351 is slidably connected to the inner wall of the corresponding slide groove 21, and the arc-shaped limit plate 35 is slidably connected to the side wall of the rotating column 2, and the inner wall of the slide groove 21 is fixedly connected with a spring 22, and the spring 22 is fixedly connected to the bottom end of the corresponding limit slider 351; the slide groove 21 guides the limit slider 351 for sliding, and the arc-shaped limit plate 35 is fixedly connected to the inner wall of the corresponding slide groove 21. The limiting plate 35 increases the contact area between the supporting plate 3 and the rotating column 2, thereby increasing the stability of the supporting plate 3 placed on one side of the rotating column 2 and preventing the supporting plate 3 from tilting. The spring 22 pushes the limiting slider 351, and the limiting slider 351 drives the supporting plate 3 to slide upward through the arc-shaped limiting plate 35, so that when the supporting plate 3 drives the connecting shaft 31 to rotate above the bevel gear 111, the connecting shaft 31 will not be interfered with and limited by the bevel gear 111 and the driving shaft 11.

[0021] A guide rod 23 is fixedly connected to the inner wall of the slide groove 21, and the spring 22 is sleeved on the side wall of the guide rod 23.

[0022] The working principle and use process of the utility model are as follows: when the gear is chamfered, the gear is sleeved on the connecting shaft 31, and the shielding ring 33 lifts the bottom of the gear, and then the rotating column 2 is controlled to drive a plurality of supporting plates 3 to rotate, and the supporting plates 3 drive the connecting shaft 31 to rotate above the bevel gear 111, and the connecting shaft 31 drives the gear to rotate between the rotating pressure plate 121 and the bevel gear 111, and then the output end of the hydraulic telescopic rod 12 is controlled to extend, and the hydraulic telescopic rod 12 drives the rotating pressure plate 121 to slide downward, and the rotating pressure plate 121 contacts and squeezes the top of the gear, and the gear transmits the squeezing force of the rotating pressure plate 121 to the connecting shaft 31 and the supporting plate 3, so that the connecting shaft 31 can drive the supporting plate 3 to slide downward, and the connecting shaft 31 approaches the bevel gear 111, and then the bevel gear 111 engages into the conical meshing groove 32, and the control motor drives the drive shaft 11 to rotate, and the drive shaft 11 drives the bevel gear 111 to rotate, and the bevel gear 111 drives the connecting shaft 31 to rotate, and the connecting shaft 31 drives the gear to rotate. At this time, the connecting shaft 31 on the outside of the supporting shell 1 is in a non-working state, so that the staff or the robot arm can replace the connecting shaft 31 in the non-working state. When chamfering the next gear, it is only necessary to control the rotation of the rotating column 2 to make the next gear reach the processing area for chamfering, so that the actual working time of the chamfering machine cutting tool is increased, and the working pause interval time is reduced, thereby improving the processing efficiency of the equipment.
