Description

Technical Field

[0001] The invention relates to the field of gear processing, and in particular to a spur gear grinding device with an anti-deviation function. Background Art

[0002] Gear mechanism is an important basic transmission element in modern machinery.

[0003] The last step in gear processing is the grinding operation. Grinding is the most important processing operation that determines gear performance. Existing gear grinding equipment uses a center shaft to fix the gear, but there is always a gap between the center shaft and the gear, which causes the gear to be flat during the grinding process. As a result, the spacing between the external teeth on the gear is inconsistent, making the gear difficult to assemble and even causing abnormal noise during operation.

[0004] The existing equipment's center fixing method makes it difficult to grind eccentric gears. During the grinding process, the eccentric gears need to locate a new rotation center from the outside to ensure that the eccentric gears rotate in the same way as spur gears, thereby reducing the operating steps of positioning the grinding equipment and improving the grinding accuracy of the eccentric gears.

[0039] Before using the spur gear grinding device with anti-misalignment function, the spur gear or eccentric gear to be ground is clamped and positioned to the secondary positioning and fixing system by a manipulator, while ensuring that the gear is placed vertically and the gear shaft hole is located on the center line.

[0045] The present embodiment describes the operation of the eccentric gear, and the specific operation method is as follows: the manipulator vertically clamps the eccentric gear, and at the same time places the center of the axial hole of the eccentric gear and the axis of the supporting circular plate 2011 in the same vertical plane, and then controls the second servo motor 208 to operate, the second servo motor 208 drives the bidirectional screw rod 207 to rotate, and the bidirectional screw rod 207 drives the two moving blocks 209 to move toward each other on the limit rod 206, at this time, the two moving blocks 209 each drive the third servo motor 2010, the supporting circular plate 2011, the first elastic member 2012, the top block 2013, the third electric slide rail 2014, the third electric slider 2015 and the supporting mechanism 20 16 moves, at this time, the top blocks 2013 on both sides contact the tooth surface of the eccentric gear, temporarily controlling the second servo motor 208 to stop running, and then controlling the two third electric slide rails 2014 to run, the two third electric slide rails 2014 each drive a third electric slider 2015 to move, and the two third electric sliders 2015 each drive a top support mechanism 2016 to move, at this time, the two top support mechanisms 2016 are positioned on both sides of the shaft hole of the eccentric gear, and then continue to control the second servo motor 208 to run, so that the two moving blocks 209 continue to move towards each other, and at this time, the top block 2013 that follows the movement begins to push the first elastic member 2012, and the first elastic member 201 2 contracts and starts to provide elastic force, then the two supporting mechanisms 2016 start to enter the shaft hole of the eccentric gear, and when the distance between the two supporting mechanisms 2016 is the smallest, the second servo motor 208 is controlled to stop running, and then the two first electric push rods 20161 on the supporting mechanism 2016 are controlled to run, and the telescopic parts of the two first electric push rods 20161 each drive a wedge frame 20162 to move, and the two wedge frames 20162 move toward each other and push four supporting rods 20164 respectively, and the four supporting rods 20164 on the same side are opened in a cross manner and support the shaft hole of the eccentric gear, so as to ensure that the eccentric gear will not be vertically deformed when subjected to the top grinding pressure. The deviation in the vertical direction ensures the quality of grinding. At the same time, the two second elastic members 20165 fixed to each support rod 20164 can ensure the return power of the support rod 20164, ensuring that the support rod 20164 can completely withdraw from the shaft hole of the eccentric gear; after completing the clamping positioning, the two third servo motors 2010 are controlled to run, and the two third servo motors 2010 each drive a supporting circular plate 211 to run. The two supporting circular plates 211 cooperate with the first elastic member 2012 and the top block 2013 to adjust the rotation mode of the eccentric gear, converting the eccentric motion into regular rotation, and then the tooth groove between the two teeth of the eccentric gear is aligned with the grinding tool;At this time, the arc-shaped electric slide rail 302 is controlled to operate, and the arc-shaped electric slide rail 302 drives the fourth electric slider 303 to move, and the fourth electric slider 303 drives the two second electric push rods 304 to make a circular motion, and the two second electric push rods 304 drive the arc-shaped carrier plate 305 to move accordingly, and at the same time, the center clamping plate 306 that follows the movement is positioned to the position of the tooth groove between the two teeth at the bottom of the eccentric gear, and then the third electric push rod 308 is controlled to operate, and the third electric push rod 308 pulls the Z-shaped rack 309 to move, and the Z-shaped rack 309 drives the two flat gears 3011. Since the teeth of the Z-shaped rack 309 are distributed up and down, the rotation directions of the two flat gears 3011 are opposite, and the two flat gears 3011 rotate in opposite directions. The wheels 3011 each drive a side clamping plate 3010 to rotate, and the two side clamping plates 3010 rotate accordingly and are positioned to the raised part between the two gear tooth pitch circles and the base circle of the eccentric gear, and then the two second electric push rods 304 are controlled to operate, and the two second electric push rods 304 drive the arc-shaped bearing plate 305 to move, and position the center clamping plate 306 and the two side clamping plates 3010 to the positions of the two gear teeth, and then the third electric push rod 308 is controlled to operate, so that the two side clamping plates 3010 completely clamp the bottom of the eccentric gear, effectively avoiding the lateral eccentricity caused by the eccentric gear when grinding the arc surface between the top circle of the upper part and the pitch circle, and preventing the eccentric gear from being offset in the horizontal direction. ;
