[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In the present invention, the circular plate is rotated by starting the second servo motor in the support table, and the rotation of the circular plate drives the gear workpiece to rotate. The rotation of the gear workpiece changes the relative position of the tooth groove of the gear workpiece and the movable block, so that the movable block can be used to chamfer and grind all the tooth grooves on the upper end of the gear workpiece. After the chamfering and grinding of the tooth grooves on the upper end of the gear workpiece is completed, the gear workpiece is flipped by a flipping drive assembly to facilitate the chamfering and grinding of the tooth grooves at the bottom end of the gear workpiece. There is no need for the staff to release and clamp the gear workpiece with a clamping rod and a spring, which saves cumbersome operating steps and improves the efficiency of chamfering and grinding the gear workpiece.

[0015] In the present invention, the rotation of the gear will drive the rotating shaft to rotate, so that the support platform, the circular plate and the gear workpiece are flipped with the rotating shaft as the axis center, so that the bottom end of the gear workpiece is flipped upward, that is, the flipping of the gear workpiece is completed. After the gear workpiece is flipped, the cylinder is started to move the push rod and the push ring in the opposite direction to reset, so that the chamfering assembly is reset, and the chamfering grinding plate is located at the tooth groove of the gear workpiece. At this time, the slide bar 2 and the rack will not move and reset, so as not to flip the gear workpiece over again. Before flipping the gear workpiece, the device first drives the chamfering assembly to move and avoid, so as to avoid motion interference. After the gear workpiece is flipped, the chamfering assembly is reset to chamfer the tooth groove at the bottom end of the gear workpiece. The structural design is reasonable, and there is no need for the staff to move the chamfering assembly separately, so it is more convenient to use.

[0016] In the present invention, the movement of the slide bar 2 will drive the slider to move, and the movement of the slide bar will apply a force to the block, so that the spring 3 at the bottom of the block is compressed. When the slide bar moves to a position misaligned with the block, the reset action of the spring 3 is used to reset the block to limit the slide bar, so that the slide bar 2 and the rack are limited and blocked, thereby limiting the position of the gear workpiece after flipping. The slide bar 2 is fixedly connected to the inner wall of the slide rail by the spring 2 to prevent the slide bar 2 and the rack from moving freely, thereby limiting the position of the gear workpiece before flipping, and preventing the gear workpiece from shaking and becoming unstable during the chamfering and grinding process.

[0017] In the present invention, the sliding sleeve is driven upward by the circular plate moving upward, and the three wedge blocks 2 are driven upward by the sliding sleeve moving upward. The upward movement of the three wedge blocks 2 will respectively apply forces to the wedge block 1, so that the three clamping rods and the limit protrusions respectively slide along the direction of the through hole, so that the gaps between the three clamping rods are gradually expanded, and the three clamping rods will apply forces to the inner wall of the gear workpiece to achieve clamping and fixing of the gear workpiece. The three clamping rods can be controlled to move simultaneously by driving the threaded rod to rotate, and the gear workpiece is clamped and fixed by the clamping rods, without the need for staff to adjust each clamping rod individually, so that the fixing of the gear workpiece is simpler and the operation is more convenient. The limit protrusions are fixedly installed on the ends of each clamping rod, and each limit protrusion is located at the upper end of the gear workpiece, which plays a supporting and limiting role during and after the flipping of the gear workpiece, and the structural design is reasonable.

[0018] In the present invention, the support table, the circular plate and the gear workpiece are all located above the collecting plate, so it is convenient to collect the debris generated during the chamfering and grinding process of the gear workpiece, and the collection of debris is more convenient. By starting the servo motor three, the movable block, the servo motor one and the chamfering and grinding sheet are rotated around the output shaft three of the servo motor three, and the position of the chamfering and grinding sheet can be adjusted in time. That is, after the chamfering and grinding of one tooth groove is completed, the position of the chamfering and grinding sheet is adjusted, and the chamfering and grinding of other tooth grooves is continued, so as to continuously chamfer and grind all the tooth grooves of the gear workpiece, thereby improving the efficiency of the chamfering and grinding of the gear workpiece and improving the practicability of the device.

The upper surface of the block 91 is designed as an inclined surface. A spring three is fixedly installed at the bottom end of the block 91. The block 91 is fixedly connected to the inner wall of the rectangular groove of the through plate 9 through the spring three. A round rod three 92 is fixedly installed at the bottom end of the block 91. The round rod three 92 movably penetrates the rectangular groove, and a pull ring 93 is fixedly connected to the round rod three 92. A collecting tray 13 is placed on the upper end of the base 1, and the collecting tray 13 is located below the support platform 2. The gear workpiece 31 is placed on the circular plate 3, and the outer end of the circular plate 3 is fixedly installed with a supporting block 32 at equal intervals on the circumference to provide support for the gear workpiece 31. Then the torsion block 54 is twisted to make the threaded rod 5 3 is rotated, and the threaded rod 53 is rotated to make the three clamping rods 4 move away from each other, so as to clamp the inner wall of the gear workpiece 31, and realize the clamping and fixing of the gear workpiece 31. After the fixing is completed, the servo motor 1 62 is started to make the chamfering grinding sheet 63 rotate, and the tooth groove of the gear workpiece 31 is chamfered by the rotation of the chamfering grinding sheet 63. By starting the servo motor 2 in the support table 2, the circular plate 3 is rotated, and the gear workpiece 31 is driven to rotate by the rotation of the circular plate 3. The relative position of the tooth groove of the gear workpiece 31 and the movable block 61 is changed by the rotation of the gear workpiece 31, so that all the tooth grooves of the upper end of the gear workpiece 31 can be chamfered by the movable block 61. After the chamfering of the tooth grooves of the upper end of the gear workpiece 31 is completed, the movable block 61 is used to grind the tooth grooves. The gear workpiece 31 is flipped by the flipping drive assembly, which is convenient for chamfering and grinding the tooth groove at the bottom end of the gear workpiece 31. There is no need for the staff to release and use the clamping rod 4 and the spring 42 to clamp and fix the gear workpiece 31, which saves cumbersome operation steps and improves the efficiency of chamfering and grinding the gear workpiece 31. When the gear workpiece 31 is flipped, the cylinder 7 is started to move the telescopic rod, and the movement of the telescopic rod will drive the push rod 71 and the push ring 72 to move. Since the push rod 71 is fixedly connected to the slide rod 65, the push rod 71 will push the slide rod 65 to slide in the slide rail 12, and the movement of the slide rod 65 will drive the chamfering assembly to move, so that the chamfering grinding sheet 63 is farther and farther away from the gear workpiece 31.The gear 23 is engaged with the rack 81, and the gear 23 is engaged with the rack 81. The movement of the rack 81 drives the gear 23 to rotate. The rotation of the gear 23 drives the shaft 22 to rotate, so that the support table 2, the circular plate 3 and the gear workpiece 31 are turned over with the shaft 22 as the axis, so that the bottom end of the gear workpiece 31 is turned upward, that is, the turning process of the gear workpiece 31 is completed. After the turning of the gear workpiece 31 is completed, the cylinder 7 is started, so that the push rod 71 and the push ring 72 move in the opposite direction to reset, so that the chamfering assembly is reset, so that the chamfering grinding sheet 63 is located at the tooth groove of the gear workpiece 31. The rack 81 will not move and reset, so that the gear workpiece 31 will not be flipped over again. Before the gear workpiece 31 is flipped, the device first drives the chamfering assembly to move and avoid to avoid motion interference. After the gear workpiece 31 is flipped, the chamfering assembly resets to chamfer the tooth groove at the bottom end of the gear workpiece 31. The structural design is reasonable, and there is no need for the staff to move the chamfering assembly separately, which is more convenient to use. When the push ring 72 pushes the slide bar 2 8 and the rack 81 to move, the movement of the slide bar 2 8 will drive the slider 84 to move. The movement of the slider 84 will apply a force to the block 91, so that the spring three at the bottom of the block 91 is compressed. When the slider 84 moves to a position misaligned with the block 91, the spring three is used to The reset action of the spring three causes the block 91 to reset and limit the slider 84, so that the slide bar 2 8 and the rack 81 are limited and blocked, thereby limiting the position of the gear workpiece 31 after the flip. The slide bar 2 8 is fixedly connected to the inner wall of the slide rail 12 by the spring 2 83 to prevent the slide bar 2 8 and the rack 81 from moving freely, thereby limiting the position of the gear workpiece 31 before flipping, and preventing the gear workpiece 31 from shaking and being unstable during the chamfering and grinding process. When fixing the gear workpiece 31, the threaded rod 53 is rotated by twisting the torsion block 54, and the connection ring 52 is driven to rotate in the annular groove by the rotation of the threaded rod 53, so as to prevent the sliding sleeve 5 from rotating with the rotation of the threaded rod 53. Since the threaded rod 53 is threadedly connected with the circular plate 3 and the connecting column 45, The circular plate 3 is displaced in the vertical direction, and the sliding sleeve 5 is driven upward by the circular plate 3, and the three wedge blocks 2 51 are driven upward by the sliding sleeve 5. The upward movement of the three wedge blocks 2 51 will respectively apply forces to the wedge blocks 1 44, so that the three clamping rods 4 and the limiting protrusions 43 slide along the direction of the through opening 33 respectively, so that the gaps between the three clamping rods 4 gradually expand, and the three clamping rods 4 will apply forces to the inner wall of the gear workpiece 31 to clamp and fix the gear workpiece 31. The three clamping rods 4 can be controlled to move simultaneously by driving the threaded rod 53 to rotate, and the gear workpiece 31 is clamped and fixed by the clamping rods 4, without the need for the staff to adjust each clamping rod 4 separately, so that the fixing of the gear workpiece 31 is simpler and the operation is more convenient.A limiting protrusion 43 is fixedly installed at the end of each clamping rod 4, and each limiting protrusion 43 is located at the upper end of the gear workpiece 31, which plays a supporting and limiting role in the turning process of the gear workpiece 31 and after the turning is completed. The structural design is reasonable. The support platform 2, the circular plate 3 and the gear workpiece 31 are all located above the collecting plate 13, which is convenient for collecting the debris generated during the chamfering and grinding of the gear workpiece 31. The collection of debris is more convenient. By starting the servo motor three 64, the movable block 61, the servo motor one 62 and the chamfering and grinding sheet 63 are driven by the servo motor three 6 The output shaft 3 of the gear 4 rotates as the axis, and the position of the chamfering grinding sheet 63 can be adjusted in time, that is, after the chamfering of one tooth groove is completed, the position of the chamfering grinding sheet 63 is adjusted to continue to chamfer other tooth grooves, so as to continuously chamfer all tooth grooves of the gear workpiece 31, thereby improving the efficiency of chamfering the gear workpiece 31 and the practicality of the device. By pulling the pull ring 93 downward, the block 91 can be moved downward to release the limit of the slide bar 8, and the slide bar 8 and the rack 81 can be reset by the elastic reset function of the spring 83.

[0030] Working principle:

[0031] The first step is to place the gear workpiece 31 on the circular plate 3. The outer end of the circular plate 3 is fixedly installed with support blocks 32 at equal intervals to provide support for the gear workpiece 31. Then, the torsion block 54 is twisted to rotate the threaded rod 53. The three clamping rods 4 move away from each other through the rotation of the threaded rod 53 to clamp the inner wall of the gear workpiece 31 to achieve clamping and fixing of the gear workpiece 31. After fixing, start the servo motor 1 62 to rotate the chamfering grinding sheet 63. The tooth groove of the gear workpiece 31 is chamfered by the rotation of the chamfering grinding sheet 63. The servo motor 2 in the support table 2 is started to rotate the circular plate 3. The rotation of the gear workpiece 31 drives the gear workpiece 31 to rotate, and the relative position of the tooth groove of the gear workpiece 31 and the movable block 61 is changed by the rotation of the gear workpiece 31, so that the movable block 61 can be used to chamfer and grind all the tooth grooves at the upper end of the gear workpiece 31. After the chamfering and grinding of the tooth grooves at the upper end of the gear workpiece 31 is completed, the gear workpiece 31 is flipped by the flip driving component to facilitate the chamfering and grinding of the tooth grooves at the bottom end of the gear workpiece 31. There is no need for the staff to release and use the clamping rod 4 and the spring 42 to clamp and fix the gear workpiece 31, which saves cumbersome operating steps and improves the efficiency of chamfering and grinding the gear workpiece 31.

[0032] The second step is to start the cylinder 7 to move the telescopic rod when the gear workpiece 31 is turned over. The movement of the telescopic rod will drive the push rod 71 and the push ring 72 to move. Since the push rod 71 is fixedly connected to the slide bar 65, the push rod 71 will push the slide bar 65 to slide in the slide rail 12. The movement of the slide bar 65 will drive the chamfering assembly to move, so that the chamfering grinding sheet 63 is farther and farther away from the gear workpiece 31. When the push ring 72 moves to contact the end of the slide bar 8, the push rod 71 and the push ring 72 continue to move. The push ring 72 will apply a thrust to the slide bar 8, so that the slide bar 8 and the rack 81 move. The gear 23 is meshed with the rack 81. The movement of the rack 81 will drive the gear 23 to rotate. The rotation of the gear 23 will drive the rotating shaft 22 to rotate, so that the support table 2, the circular plate 3 and the gear The wheel workpiece 31 is flipped with the rotating shaft 22 as the axis, so that the bottom end of the gear workpiece 31 is flipped upward, that is, the flipping process of the gear workpiece 31 is completed. After the gear workpiece 31 is flipped, the cylinder 7 is started to make the push rod 71 and the push ring 72 move and reset in the opposite direction, so that the chamfering assembly is reset, and the chamfering grinding sheet 63 is located at the tooth groove of the gear workpiece 31. At this time, the slide bar 28 and the rack 81 will not move and reset, so that the gear workpiece 31 will not be flipped over again. Before the gear workpiece 31 is flipped, the device first drives the chamfering assembly to move and avoid to avoid motion interference. After the gear workpiece 31 is flipped, the chamfering assembly is reset to chamfer the tooth groove at the bottom end of the gear workpiece 31. The structural design is reasonable, and there is no need for the staff to move the chamfering assembly separately, which is more convenient to use.

[0033] The third step is that when the push ring 72 pushes the slide bar 2 8 and the rack 81 to move, the movement of the slide bar 2 8 will drive the slider 84 to move, and the movement of the slider 84 will apply a force to the block 91, so that the spring three at the bottom of the block 91 is compressed. When the slide bar 84 moves to a position misaligned with the block 91, the spring three is used to reset the block 91 to limit the slide bar 84, so that the slide bar 2 8 and the rack 81 are limited and blocked, thereby limiting the position of the gear workpiece 31 after the flipping. The slide bar 2 8 is fixedly connected to the inner wall of the slide rail 12 by the spring two 83 to prevent the slide bar 2 8 and the rack 81 from moving freely, thereby limiting the position of the gear workpiece 31 before flipping, and preventing the gear workpiece 31 from shaking and being unstable during the chamfering process.

[0034] In the fourth step, when fixing the gear workpiece 31, the threaded rod 53 is rotated by twisting the torsion block 54, and the rotation of the threaded rod 53 drives the connecting ring 52 to rotate in the annular groove to prevent the sleeve 5 from rotating with the rotation of the threaded rod 53. Since the threaded rod 53 is threadedly connected with the circular plate 3 and the connecting column 45, the circular plate 3 is displaced in the vertical direction, and the upward movement of the circular plate 3 drives the sleeve 5 to move upward, and the upward movement of the sleeve 5 drives the three wedge blocks 2 51 to move upward. The upward movement of the three wedge blocks 2 51 will respectively apply a force to the wedge block 1 44, so that the three clamping rods 4 and the limiting protrusion 43 slide along the direction of the through-port 33 respectively, so that the three clamping rods 4 are connected. The gap gradually expands, and the three clamping rods 4 will exert a force on the inner wall of the gear workpiece 31 to achieve the clamping and fixing of the gear workpiece 31. The three clamping rods 4 can be controlled to move simultaneously by driving the threaded rod 53 to rotate. The gear workpiece 31 is clamped and fixed by the clamping rods 4, and there is no need for the staff to adjust each clamping rod 4 separately, which makes the fixing of the gear workpiece 31 simpler and more convenient to operate. A limiting protrusion 43 is fixedly installed at the end of each clamping rod 4, and each limiting protrusion 43 is located at the upper end of the gear workpiece 31, which plays a supporting and limiting role during and after the turning process of the gear workpiece 31, and the structural design is reasonable;

[0035] In the fifth step, the support table 2, the circular plate 3 and the gear workpiece 31 are all located above the collecting plate 13, so that the debris generated during the chamfering and grinding of the gear workpiece 31 can be collected, and the collection of debris is more convenient. By starting the servo motor three 64, the movable block 61, the servo motor one 62 and the chamfering and grinding sheet 63 rotate around the output shaft three of the servo motor three 64, and the position of the chamfering and grinding sheet 63 can be adjusted in time, that is, after the chamfering and grinding of one tooth groove is completed, the position of the chamfering and grinding sheet 63 is adjusted, and the chamfering and grinding of other tooth grooves is continued, so as to continuously chamfer and grind all the tooth grooves of the gear workpiece 31, thereby improving the efficiency of the chamfering and grinding of the gear workpiece 31 and improving the practicability of the device. By pulling the pull ring 93 downward, the block 91 can be moved downward to release the limit on the slide rod two 8, and the slide rod two 8 and the rack 81 can be reset by the elastic reset action of the spring two 83.
