[0002] Forging is an important metal processing technology. It applies pressure to metal blanks through forging equipment to make them plastically deform, thus obtaining forgings with certain shapes, sizes and mechanical properties. During the processing, the internal structure of metal materials is optimized, the grains are refined, and the defects are reduced under the action of high temperature and high pressure, thereby significantly improving the strength, toughness and other mechanical properties of the materials. Forgings are widely used in many fields such as aerospace, automobiles, and machinery manufacturing. Most of the key components such as aircraft engine blades, automobile crankshafts, and gears of large machinery are made through forging processing. The quality of forgings is directly related to the reliability and safety of the products, and is an indispensable key link in modern industrial production.

[0015] A method for using a positioning device for processing annular forgings comprises the following steps: S1. In the initial state, the driven bevel gear faces upward, the inner support contact block is retracted, the annular forging to be processed is held outside the inner support contact block, the fixture motor is started to drive the fixture worm and the fixture worm gear to rotate, the fixture worm gear drives the inner rotating disk to rotate, the linear rod is pulled outward through the spiral groove, the linear rod and the inner support contact block extend outward and clamp the annular forging inside; S2. A processing device for forging the surface of an annular forging is installed in the processing mounting frame. The machine arm moves to the surface of the annular forging, and the rotating motor drives the active dial to rotate. The active dial drives the driven groove wheel to produce intermittent rotation. The active cone column and the driven cone column are connected by an adjusting belt to form a belt transmission. The adjusting motor drives the threaded shaft to form a thread transmission, and drives the dialing platform and the adjusting belt to move on the surfaces of the active cone column and the driven cone column. According to the different positions of the adjusting belt, the diameter of the cross section where the contact surface with the active cone column and the driven cone column is located is also different, thereby adjusting the transmission ratio of the driven cone column output, and realizing intermittent transmission with adjustable output disk; S3. In the initial state, the movable output bevel gear is meshed with the fixed output bevel gear, and the bevel gear connecting groove is not connected to the bevel gear connecting pin. The output disc drives the control input shaft to rotate during rotation. The control input shaft connects the control output shaft and rotates it through the cooperation between the control engaging groove and the control engaging pin, and finally realizes the rotation of the movable output bevel gear, driving the fixed output bevel gears on both sides to rotate in opposite directions. The fixed output bevel gear transmits the rotation to the active bevel gears on both sides through the action of the bevel gear input pulley, the bevel gear belt and the bevel gear output pulley, and the rotation is opposite, driving the driven bevel gear sandwiched between the active bevel gears to rotate intermittently in the horizontal direction. The surface of the forging on its processing mounting frame is constantly changed for processing, so that the processing mounting frame can completely process the annular forging for one circle; S4. During the rotation of the output disc, the rotation is dispersed to the separated output pulleys and the control worm on both sides through the separation input pulley and the separation belt, which respectively drive the control worm wheels on both sides to rotate in the same direction. During the rotation of the control worm wheel, the winding elastic column is wound into a spiral line to store the rotation. When the output disc rotates one circle, the top of the annular forging is processed one circle. At this time, the push block pushes the pull ring base away. The pull ring base pulls the control output shaft and the movable output bevel gear backward through the output shaft pull ring. At this time, the fixed output bevel gear is no longer engaged with the movable output bevel gear, and the control engaging groove is also separated from the control engaging pin. At this time, the output disc does not play any role in the output bevel gear. While the pull ring base retreats, under the action of the hinged push-pull rod, the direct-acting pull ring pulls the direct-acting shafts on both sides inward. At this time, the direct-acting shaft is connected to the fixed output bevel gear through the bevel gear connecting groove and the bevel gear connecting pin, and the control worm wheel is separated from the control worm and is no longer self-locked. The elastic column reverses and resets to the initial state and drives the control worm gear and the direct-acting shaft to rotate. At this time, the direct-acting shaft drives the fixed output bevel gear to rotate and the directions on both sides are the same. Similarly, the bevel input pulley, the bevel gear belt and the bevel output pulley will transmit the rotation to the active bevel gears on both sides. At this time, the active bevel gears have the same direction, driving the driven bevel gear and the flip inner support contact block to turn the original bottom of the annular forging upward. As the control worm gears on both sides approach each other, the elastic column is pulled again. When the pushing protrusion is separated from the pull ring base, the pull ring base is pulled to reset and restored to the state where the output bevel gear and the movable output bevel gear are meshed, and the bevel gear connecting groove and the bevel gear connecting pin are not connected. The mechanical arm drives the processing mounting frame to descend, and the rotating motor reverses and continues to drive the processed annular forging to rotate, thereby processing the other side. The elastic column also rewinds in the opposite direction. When the pushing protrusion pushes the pull ring base away again, the elastic column resets and causes the driven bevel gear and the flip inner support contact block to flip to the top again.

[0016] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, by cooperating with the positioning mechanism and the positioning control mechanism, the forward and reverse rotation of the active bevel gear in the positioning mechanism is controlled, and different actions of the annular forging during the processing are realized, so as to ensure the smooth progress of the processing process, and realize the horizontal rotation and flipping of the annular forging during the processing, so that different parts of the annular forging can be accurately aligned with the processing mounting frame in sequence, so as to carry out all-round processing. The processing mounting frame can completely process the annular forging around a circle, including the top and the bottom, without the need for frequent manual adjustment of the position of the forging, thereby greatly improving the processing efficiency.

[0017] In the present invention, the intermittent rotation of the annular forging is controlled by the cooperation of the positioning mechanism and the rotation control mechanism, and the angle of each rotation is steplessly adjusted to set the interval of each processing position on the annular forging, and the interval is used for processing. In this way, the processing time and rhythm can be reasonably arranged, and the processing errors and equipment wear that may be caused by continuous rotation are avoided, so that the processing process can be carried out according to the predetermined rhythm and position.

[0018] In the present invention, the inner support clamp mechanism is provided to stably clamp the annular forging inside the device so that it will not be displaced or shaken during the processing, thereby ensuring the processing accuracy, and the inner support clamp can cooperate with the rotation and flipping of the positioning mechanism.

A bevel input pulley 36 is fixedly connected to the outer surface of the bevel input pulley 36. A bevel connecting pin 361 is fixedly connected to the outer surface of the bevel input pulley 36. When the driving bevel gear 32 rotates in the opposite direction, it is equivalent to applying opposite racks on both sides of the driven bevel gear 34, and the driven bevel gear 34 rotates in situ in the horizontal direction. When the driving bevel gear 32 rotates in the same direction, the driven bevel gear 34 is pushed up or down on both sides at the same time, and the driven bevel gear 34 flips over. The positive and reverse rotation of the driving bevel gear 32 is controlled by the positioning control mechanism 6.

[0024] There are two active bevel gears 32 , and the two active bevel gears 32 are symmetrically distributed with the central axis of the rotating shaft 31 as the symmetry axis.

A spiral groove 441 is provided on the outer surface of the inner rotating plate 44, and a direct-acting rod 45 is slidably connected to the inner surface of the spiral groove 441. The direct-acting The other end of the rod 45 is fixedly connected to an inner support contact block 451. Through the setting of the inner support clamp mechanism 4, during use, the clamp motor 42 drives the worm and worm gear structure composed of the clamp worm 43 and the clamp worm wheel 431 to rotate. The worm and worm gear structure has self-locking properties, which can prevent the inner rotating disk 44 from reversing when the clamp motor 42 stops rotating, resulting in the inner support contact block 451 moving inside the box and failing to clamp the forging. The spiral groove 441 is an Archimedean spiral line shape, and the rotation angle is proportional to the radius.

The active cone column 53 and the driven cone column 531 are used to change the transmission ratio and control the angle of each horizontal rotation of the forging, so as to set the interval of each processing position on the annular forging. The transmission ratio between the active cone column 53 and the driven cone column 531 is controlled by the position of the adjustment belt 553. The cone column 53 and the driven cone column 531 are both conical, with the same shape but opposite installation positions. The length of the adjusting belt 553 remains unchanged, and when it is sleeved on the active cone column 53 and the driven cone column 531, the cross-section of the contact surface with the active cone column 53 and the driven cone column 531 is equivalent to the pulley. No matter when, the sum of the diameters of the cross-sections of the contact surfaces of the active cone column 53 and the driven cone column 531 remains unchanged. When the adjusting belt 553 moves, the diameter of one of the cross-sections decreases while the other increases, which is equivalent to the change in the diameter of the pulley, thereby steplessly adjusting the transmission ratio, so that the annular forging can adjust the angle of each rotation according to the required processing interval.

Through the setting of the positioning control mechanism 6, during use, the separation belt 61 is used to distribute the rotation of the separation input pulley 541 to the control worm 613 on both sides. Since the diameter of the separation input pulley 541 is large and the diameter of the control worm 613 is small, the transmission ratio is large, which drives the control worm 613 and the control worm wheel 614 to rotate. The control worm 613 and the control worm wheel 614 have a self-locking effect to prevent the control worm wheel 614 from reversing when the winding elastic column 615 is rotated.

[0031] In this embodiment, Figure 1 , Figure 2 , Figure 3 As shown, the device housing 1 is used to install and protect the internal components, and the mechanical arm 2 drives the processing mounting frame 21 to achieve lifting and lateral movement, so that it can align the height position of the clamped forging and align the forging surface; In this embodiment, Figure 4 , Figure 5 As shown, the bevel input pulley 36 transmits the rotation to the driving bevel gear 32 through the belt drive, and the driven bevel gear 34 rotates horizontally or flips according to whether the driving bevel gears 32 on both sides rotate in the same or opposite direction; In this embodiment, Figure 6 As shown, the active dial 521 and the driven groove wheel 522 are used to convert the uniform rotation of the rotary motor 52 into intermittent rotation, so that the forging has a pause interval during the horizontal rotation process, and the interval is used for processing. The active cone column 53 and the driven cone column 531 are used to change the transmission ratio, control the angle of each horizontal rotation of the forging, and when the adjustment belt 553 moves, the diameter of one section decreases and the other increases, which is equivalent to the change of the pulley diameter, thereby steplessly adjusting the transmission ratio; In this embodiment, Figure 7As shown, at this time, the bevel gear connecting groove 625 is separated from the bevel gear connecting pin 361, the movable output bevel gear 633 is connected to the fixed output bevel gear 632, the separation input pulley 541 drives the movable output bevel gear 633 to rotate, and drives the fixed output bevel gears 632 on both sides to rotate in opposite directions, and the annular forging rotates horizontally; In this embodiment, Figure 8 As shown, each rotation of the separation input pulley 541 indicates that the annular forging also rotates one circle. At this time, the top surface processing is completed, and the push block 542 pushes the pull ring base 622 away. At this time, the bevel gear connecting groove 625 is connected with the bevel gear connecting pin 361, and the movable output bevel gear 633 is separated from the fixed output bevel gear 632. The fixed output bevel gear 632 rotates together, and the annular forging turns over; In this embodiment, Fig. 9 As shown, when the pull ring base 622 moves backward, under the action of the hinged push-pull rod 623, the direct-acting pull ring 621 pulls the direct-acting shafts 62 on both sides inward, and the groove 11 limits the moving path of the direct-acting pull ring 621 to make it move horizontally; In this embodiment, Fig.10 As shown, the bevel gear connecting groove 625 and the bevel gear connecting pin 361 are engaged through grooves and protrusions.

When the control output shaft 65 drives the control engaging pin 652 to move relative to each other, the control engaging pin 652 is at the rear end of the control engaging groove 641 and is not engaged.

[0032] A method for using a positioning device for processing annular forgings comprises the following steps: S1. In the initial state, the driven bevel gear 34 faces upward, the inner support contact block 451 is retracted, the annular forging to be processed is held outside the inner support contact block 451, the clamp motor 42 is started to drive the clamp worm 43 and the clamp worm gear 431 to rotate, the clamp worm gear 431 drives the inner rotating disk 44 to rotate, the linear rod 45 is pulled outward through the spiral groove 441, the linear rod 45 and the inner support contact block 451 extend outward and clamp the annular forging inside; S2. A processing device for forging the surface of an annular forging is installed in the processing mounting frame 21. The robot arm 2 moves to the surface of the annular forging. The rotating motor 52 drives the active dial 521 to rotate. The active dial 521 drives the driven groove wheel 522 to produce intermittent rotation. The active cone column 53 and the driven cone column 531 form a belt transmission through the adjusting belt 553. The adjusting motor 55 drives the threaded shaft 551 to form a thread transmission, driving the dialing platform 552 and the adjusting belt 553 to move on the surfaces of the active cone column 53 and the driven cone column 531. According to the different positions of the adjusting belt 553, the diameter of the cross section where the contact surface with the active cone column 53 and the driven cone column 531 is located is also different, thereby adjusting the transmission ratio of the output of the driven cone column 531, and realizing the intermittent transmission that the output disk 54 can adjust; S3. In the initial state, the movable output bevel gear 633 is meshed with the fixed output bevel gear 632, and the bevel gear connecting groove 625 is not connected to the bevel gear connecting pin 361. During the rotation of the output disc 54, the control input shaft 64 is driven to rotate. The control input shaft 64 is connected to the control output shaft 65 and rotates through the cooperation between the control engaging groove 641 and the control engaging pin 652, and finally realizes the rotation of the movable output bevel gear 633, driving the fixed output bevel gears 632 on both sides to rotate in opposite directions. The fixed output bevel gear 632 transmits the rotation to the active bevel gears 32 on both sides through the action of the bevel gear input pulley 36, the bevel gear belt 35 and the bevel gear output pulley 321, and the rotation is opposite, driving the driven bevel gear 34 sandwiched between the active bevel gears 32 to rotate intermittently in the horizontal direction. The surface of the forging on its processing mounting frame 21 is constantly changed for processing, so that the processing mounting frame 21 can completely process the annular forging for one circle; S4. During the rotation of the output disk 54, the rotation is dispersed to the separation output pulleys 612 and the control worm 613 on both sides through the separation input pulley 541 and the separation belt 61, which respectively drive the control worm wheels 614 on both sides to realize the same direction rotation. During the rotation, the control worm wheel 614 winds the winding elastic column 615 into a spiral line to store the rotation. When the output disk 54 rotates one circle, the top of the annular forging is processed one circle. At this time, the protrusion 542 is pushed to push the pull ring base 622 away. The pull ring base 622 controls the output shaft 65 and the movable The movable output bevel gear 633 is pulled backward, at this time, the fixed output bevel gear 632 is no longer meshed with the movable output bevel gear 633, and the control engaging groove 641 is also separated from the control engaging pin 652. At this time, the output disc 54 does not have any effect on the output bevel gear, and the pull ring base 622 retreats while the direct-acting pull ring 621 pulls the direct-acting shafts 62 on both sides inward under the action of the hinged push-pull rod 623. At this time, the direct-acting shaft 62 is connected to the fixed output bevel gear 632 through the bevel gear connecting groove 625 and the bevel gear connecting pin 361, and the control worm wheel 614 is no longer separated from the control worm 613 Being self-locked, the elastic column 615 reverses and resets to the initial state and drives the control worm gear 614 and the direct-acting shaft 62 to rotate. At this time, the direct-acting shaft 62 drives the fixed output bevel gear 632 to rotate and the directions on both sides are the same. Similarly, under the action of the bevel input pulley 36, the bevel gear belt 35 and the bevel output pulley 321, the rotation is transmitted to the active bevel gears 32 on both sides. At this time, the active bevel gears 32 have the same direction, driving the driven bevel gear 34 and the flip inner support contact block 451, turning the original bottom of the annular forging upwards. As the control worm gears 614 on both sides approach each other, the elastic column 615 is pulled again. When the push-button 542 is disengaged from the pull-ring base 622, the pull-ring base 622 is pulled to reset, and the output bevel gear is again restored to the state of meshing with the movable output bevel gear 633, and the bevel gear connecting groove 625 is not connected with the bevel gear connecting pin 361. The robot arm 2 drives the processing mounting frame 21 to descend, and the rotating motor 52 reverses and continues to drive the processing annular forging to rotate so as to process the other side. The elastic column 615 is also reversed and rolled up. When the push-button 542 pushes the pull-ring base 622 away again, the elastic column 615 is reset to make the driven bevel gear 34 and the flip inner support contact block 451 flip to the top again.
