[0015] A processing technology for a high-precision gearbox comprises the following steps: Switching steps: The mounting table rotates a certain angle along the main table, and the switching gear box rotates to switch the positions of both ends; Forging steps: the driving shaft device drives the heating device to the processing position; the driving device drives the driving shaft device and the heating coil to move along the processing position of the gear box; the shaft body rotates along the shaft seat, and the heating coil always faces the processing position of the gear box; The driving shaft device drives the forging device to the processing position; the driving device drives the driving shaft device and the forging device to move along the processing position of the gear box; the shaft body rotates along the shaft seat, and the vertical body and the roller can act on both sides of the same processing position of the gear box at the same time; the shaft body rotates along the shaft seat, and the vertical body and the roller can also act on the same processing position of the gear box in sequence; The driving shaft device drives the cooling device to the processing position; the driving device drives the driving shaft device and the cooling device to move along the processing position of the gear box; the sealing plate contacts the processing position of the gear box; the nozzle sprays the cooling medium toward the sealing plate, and the cooling medium contacts the processing position of the gear box for many times; the nozzle sprays the cooling medium toward the processing position of the gear box, and the cooling medium gradually fills the cooling space, and the processing position of the gear box is immersed in the cooling medium; Machining steps: The drive shaft device drives the processing device to grind the gear box processing position.

[0016] Compared with the prior art, the beneficial technical effects of the present invention are as follows: (1) the processing position of the gear box is heated by a heating device, and then the processing position of the gear box is forged and rolled by a forging device, and finally the processing position of the gear box is cooled by a cooling device; the workbench completes the position switching of the left and right sides of the gear box, and the processing device grinds the processing position of the gear box; rolling and grinding on both sides of each gear box can be carried out simultaneously, which improves the hardness of the processing position of the gear box and improves the processing efficiency of the gear box; by rolling the processing position of the gear box, the processing allowance of the processing position of the gear box is reduced to adapt to the grinding process, and the grinding method ensures the processing accuracy.

[0017] (2) One end of the baffle is hinged on the support platform, and the other end of the baffle can be fixed to the support platform by bolts; a contoured notch is formed on the baffle, and when the baffle presses down the gear box, the contoured notch contacts the upper surface of the middle position of the gear box; the baffle separates the two ends of the gear box, thereby avoiding interference between the two ends of the gear box during processing.

[0018] (3) The moving speed of the heating coil is controlled by the driving device, and the power of the heating coil is adjusted to control the internal and external temperatures of the gear box processing position; when the gear box processing position is the end faces at the left and right ends of the gear box, the path of the driving shaft device driven by the driving device is irregular. In order to ensure the heating effect of the heating coil, the angle of the heating coil is adjusted by rotating the shaft body along the shaft seat so that the heating coil is always facing the gear box processing position.

[0019] (4) The driving device drives the forging device close to the processing position of the gear box, so that the roller forms pressure on the surface of the processing position of the gear box, and the forging size of the processing position of the gear box is determined by adjusting the position of the roller; the pressure of the roller corresponds to the power of the vibrating device driving the vertical body, and the power of the vibrating device driving the vertical body corresponds to the deformation of the processing position of the gear box; the greater the deformation of the processing position of the gear box, the greater the power of the vibrating device driving the vertical body, and the greater the pressure of the roller; the smaller the deformation of the processing position of the gear box, the smaller the power of the vibrating device driving the vertical body, and the smaller the pressure of the roller; The vibration device drives the pitot to forge the back of the gear box processing position. Due to the lack of roller restrictions, the deformation degree of the gear box processing position increases; when the roller continues to rotate and re-contacts the gear box processing position, it re-rolls the gear box processing position to limit the size of the gear box processing position; by selecting rollers with different sizes of cuts, the deformation amount of the gear box processing position is controlled to meet the mechanical performance requirements of the gear box processing position.

[0020] (5) During the first cooling process, the cooling device moves along the processing position of the gear box, and the other end of the sealing plate contacts the processing position of the gear box. The sealing plate will vibrate during the movement of the cooling device; the temperature of the processing position of the gear box is relatively high, and the temperature is transmitted to the other end of the sealing plate; after the processing position of the gear box contacts the cooling medium, the cooling medium vaporizes rapidly, aggravating the vibration of the sealing plate; driven by the sealing plate, the cooling medium contacts the processing position of the gear box for many times and vaporizes, causing the surface temperature of the processing position of the gear box to drop rapidly; During the second cooling process, the cooling device moves along the gearbox processing position, and the cooling space is not a sealed space; the amount of cooling medium sprayed by the nozzle is greater than the leakage of cooling medium in the cooling space, and the cooling medium gradually fills most of the space in the cooling space; the gearbox processing position is immersed in the cooling medium to achieve complete cooling of the gearbox processing position.

[0021] (6) After the rolling of the roller and the hammering of the vertical body are completed, the roller continues to move and no longer contacts the cylindrical block, and the vertical body continues to move. However, due to the continuous hammering of the gearbox processing position, the cylindrical block becomes loose, and then the cylindrical block is recovered through the sleeve; the second spring pushes the first pressure plate to swing toward the outlet direction; when the outlet of the sleeve approaches and connects to the end face mounting hole, the second spring pushes the first pressure plate to swing, and the first pressure plate pushes the cylindrical block near the outlet of the sleeve to move out of the sleeve and into the end face mounting hole; The third spring pushes the second pressure plate to press the cylindrical blocks in the direction of arrangement; when a group of cylindrical blocks moves out of the sleeve, the third spring extends and pushes the second pressure plate to press the arranged cylindrical blocks, so that the next group of cylindrical blocks is close to the exit direction; when the cylindrical blocks move into the sleeve from the entrance direction, the cylindrical blocks push the second pressure plate to cause the third spring to contract; it takes a certain amount of time for the cylindrical blocks to move into the sleeve, and an elastic paddle is provided at the exit of the sleeve to ensure that the roller and the vertical body can continue to move during the recovery process; as the cylindrical blocks gradually move into the sleeve, the cylindrical blocks push the elastic paddle to bend inward, and after the cylindrical blocks move into the sleeve, the elastic paddle is elastically reset outward, and the elastic paddle covers the entrance of the sleeve.

Figure 1-Figure 5 and Figure 9-11 As shown, the present invention discloses a processing system and a processing technology for a high-precision gear box.

[0036] The processing system of the high-precision gearbox includes: a workbench 1 that supports the middle position of the gearbox and separates the two ends of the gearbox, a driving device 2 arranged on both sides of the workbench 1, a processing device 3 arranged at the driving end of the driving device 2 on one side, a driving shaft device 4 arranged at the driving end of the driving device 2 on the other side, a heating device 5 for heating the processing position of the gearbox, a forging device 6 for forging the processing position of the gearbox, and a cooling device 7 for cooling the processing position of the gearbox.

[0037] The gearboxes are installed in parallel on the workbench 1, and the workbench 1 drives the gearboxes to rotate to switch the positions of the left and right sides of the gearboxes, so that the left and right sides of the gearboxes complete the forging and machining processes respectively.

[0038] The driving device 2 on one side drives the processing device 3 to move along the processing position on one side of the gear box, and the processing device 3 performs machining on one side of the gear box. The driving device 2 on the other side drives the drive shaft device 4 to move along the processing position on the other side of the gear box, and the heating device 5, forging device 6 and cooling device 7 sequentially heat, forge and cool the processing position on the other side of the gear box.

[0039] The heating device 5, the forging device 6 and the cooling device 7 are distributed on the driving shaft device 4, and the driving shaft device 4 drives the heating device 5, the forging device 6 and the cooling device 7 to switch positions. The driving shaft device 4 drives the heating device 5 to enter the processing position, and the driving device 2 on the other side drives the driving shaft device 4 to move along the processing position on the other side of the gear box, and drives the heating device 5 to complete the heating of the processing position on the other side of the gear box. The driving shaft device 4 drives the forging device 6 to enter the processing position, and the driving device 2 on the other side drives the driving shaft device 4 to move along the processing position on the other side of the gear box, and drives the forging device 6 to complete the forging of the processing position on the other side of the gear box. The driving shaft device 4 drives the cooling device 7 to enter the processing position, and the driving device 2 on the other side drives the driving shaft device 4 to move along the processing position on the other side of the gear box, and drives the cooling device 7 to complete the cooling of the processing position on the other side of the gear box.

[0040] The gearbox processing position is heated by the heating device 5, and then forged and rolled by the forging device 6, and finally cooled by the cooling device 7. The workbench 1 completes the position switching of the left and right sides of the gearbox, and the processing device 3 grinds the gearbox processing position. The rolling and grinding of both sides of each gearbox can be carried out at the same time, which improves the hardness of the gearbox processing position and improves the processing efficiency of the gearbox. The processing allowance of the gearbox processing position is reduced by rolling the gearbox processing position to adapt to the grinding process, and the grinding method ensures the processing accuracy.

[0041] The processing position of the gearbox is the contact surface for installing gears, gear shafts or end covers. The processing positions of the gearbox are located at the end faces at the left and right ends of the gearbox and the through hole in the middle of the gearbox. Grind the end faces at the left and right ends of the gearbox, grind the through holes on the end faces at the left and right ends of the gearbox, and grind the inner surface of the through hole in the middle of the gearbox. The requirements for the mechanical properties and dimensional accuracy of the processing position of the gearbox are high. The processing position of the gearbox is forged by the forging device 6, which improves the mechanical properties of the processing position of the gearbox and makes the size of the processing position of the gearbox close to the requirements of the drawing. At this time, the processing allowance of the processing position of the gearbox is small, and the processing device 3 grinds the dimensional accuracy of the processing position of the gearbox to meet the requirements of the drawing.

[0042] The workbench 1 comprises: a main table 11, a mounting table 12 rotatably arranged on the main table 11, a support table 13 arranged on the mounting table 12, a mounting block 14 arranged on the mounting table 12 and pressing the gear box, and a baffle 15 separating the two ends of the gear box.

[0043] The gear box is placed on the support platform 13, and the baffle 15 is arranged on the support platform 13 and presses down the gear box.

[0044] The mounting table 12 is distributed on the main table 11 in the front-to-back direction. The lower end of the support table 13 is connected to the mounting table 12. The upper end of the support table 13 forms a contour surface to contact the lower surface of the middle position of the gear box, and the contour surface of the support table 13 forms a reference surface, which contacts the processed surface of the gear box.

[0045] The mounting block 14 is connected to the mounting platform 12 by bolts. The bolts pass through the mounting block 14 and are threadedly connected to the mounting platform 12. After the bolts are tightened, the mounting block 14 presses down the lower part of the gear box.

[0046] One end of the baffle 15 is hinged on the support platform 13, and the other end of the baffle 15 can be fixed on the support platform 13 by bolts. A contoured notch is formed on the baffle 15. When the baffle 15 presses down the gear box, the contoured notch contacts the upper surface of the middle position of the gear box. The baffle 15 separates the two ends of the gear box, avoiding interference between the two ends of the gear box when processing.

[0047] After the gearbox is processed, the baffle 15 is opened manually, the mounting block 14 is removed, and the gearbox is lifted and taken out. Afterwards, the unprocessed gearbox is hung on the support platform 13, and the mounting block 14 and the baffle 15 are fixedly installed.

[0048] The main platform 11 is provided with a third power device 16, and a gear is provided at the driving end of the third power device 16. A gear ring is sleeved on the mounting platform 12, and the gear meshes with the gear ring, so that the third power device 16 can drive the mounting platform 12 to rotate a certain angle.

[0049] Exemplarily, the driving device 2 is a machine tool screw moving module. The processing device 3 includes a machine tool spindle 31 and a grinding head 32 mounted on the machine tool spindle 31. The machine tool spindle 31 drives the grinding head 32 to rotate, and the grinding head 32 completes the grinding of the gear box processing position.

[0050] The processing system of the high-precision gearbox can also be equipped with a tool magazine and a tool changing mechanism to replace the grinding head 32 of different specifications.

[0051] The driving shaft device 4 comprises: a shaft seat 41 and a shaft body 42 rotatably arranged on the shaft seat 41. The heating device 5, the forging device 6 and the cooling device 7 are distributed on the shaft body 42.

[0052] A gear ring is sleeved on the shaft body 42. A motor is installed in the shaft seat 41, and a gear is installed at the motor drive end. The gear meshes with the gear ring, and the motor drives the gear to rotate, and the gear drives the gear ring and the shaft body 42 to rotate a certain angle.

[0053] There are two groups of drive shaft devices 4 located at the other end of the gear box. One group of drive shaft devices 4 completes the processing of the end faces at the left and right ends of the gear box, and the other group of drive shaft devices 4 completes the processing of the through hole in the middle position of the gear box.

[0054] The heating device 5 includes: a heating coil 51 disposed on the shaft 42. One end of the heating coil 51 is connected to a power source through a controller, and the controller adjusts the power of the heating coil 51. The other end of the heating coil 51 is wound to form a structure, and the structure is parallel to the processing position of the heating gear box.

[0055] When the gear box processing position is the end surface at the left and right ends of the gear box, the other end of the heating coil 51 is bent into an N shape. The heating coil 51 is located on both sides of the gear box processing position, and the heating coil 51 heats the gear box processing position.

[0056] When the gear box processing position is a through hole in the middle of the gear box, the other end of the heating coil 51 is bent into a cylindrical shape. The heating coil 51 is located in the gear box processing position, and the heating coil 51 heats the gear box processing position.

[0057] The moving speed of the heating coil 51 is controlled by the driving device 2, and the power of the heating coil 51 is adjusted, so as to control the internal and external temperatures of the processing position of the gear box.

[0058] When the gear box processing position is the end faces at the left and right ends of the gear box, the path of the driving device 2 driving the driving shaft device 4 to move is irregular. In order to ensure the heating effect of the heating coil 51, the angle of the heating coil 51 is adjusted by rotating the shaft body 42 along the shaft seat 41, so that the heating coil 51 is always facing the gear box processing position.

[0059] The forging device 6 includes: a first bracket 61 arranged on the shaft body 42 , a roller 62 at the rolling gear box processing position, a vibration device 63 arranged on the first bracket 61 , and a vertical body 64 arranged at the driving end of the vibration device 63 .

[0060] In which, for example, there are multiple groups of rollers 62, and the rollers 62 are arranged to rotate in parallel on the first bracket 61. The vibration device 63 drives the drop body 64 to forge the gear box processing position. The drop body 64 and the roller 62 can act on both sides of the same processing position of the gear box at the same time. The drop body 64 and the roller 62 are arranged oppositely, the roller 62 contacts the gear box processing position, and the drop body 64 forges the back of the gear box processing position.

[0061] The vibration device 63 is installed on the first bracket 61 through a vibration-damping block. The vibration device 63 drives the pitot 64 to hammer the roller 62. When the gearbox processing position is the end faces at the left and right ends of the gearbox, the path of the driving device 2 driving the driving shaft device 4 to move is irregular. In order to ensure that the hammering force of the pitot 64 acts on the back of the gearbox processing position and the roller 62 contacts the surface of the gearbox processing position, the shaft body 42 rotates along the shaft seat 41 to adjust the angle of the forging device 6 so that the surface of the gearbox processing position is flat. During the movement of the forging device 6, the roller 62 rolls along the gearbox processing position to avoid scratching the gearbox processing position.

[0062] The driving device 2 drives the forging device 6 to approach the gearbox processing position, so that the roller 62 forms pressure on the surface of the gearbox processing position, and the forging size of the gearbox processing position is determined by adjusting the position of the roller 62. The pressure of the roller 62 corresponds to the power of the vibration device 63 driving the pit 64, and the power of the vibration device 63 driving the pit 64 corresponds to the deformation of the gearbox processing position. The greater the deformation of the gearbox processing position, the greater the power of the vibration device 63 driving the pit 64, and the greater the pressure of the roller 62. The smaller the deformation of the gearbox processing position, the smaller the power of the vibration device 63 driving the pit 64, and the smaller the pressure of the roller 62.

[0063] The outer surface of the roller 62 is formed with a cutout 621, so that after the roller 62 rotates a certain angle, the roller 62 is separated from the gear box processing position, and the outer surface of the roller 62 does not contact the gear box processing position. The vibration device 63 drives the vertical body 64 to forge the back of the gear box processing position. Due to the lack of the restriction of the roller 62, the deformation degree of the gear box processing position is enlarged. When the roller 62 continues to rotate and contacts the gear box processing position again, the gear box processing position is rolled again, and the size of the gear box processing position is limited.

[0064] The size of the cutout 621 corresponds to the degree of deformation of the gearbox processing position. The larger the size of the cutout 621, the greater the degree of deformation of the gearbox processing position. By selecting rollers 62 with cutouts 621 of different sizes, the deformation of the gearbox processing position is controlled to meet the mechanical performance requirements of the gearbox processing position.

[0065] As the driving shaft device 4 continues to move, the roller 62 continues to rotate, and the outer surface of the roller 62 contacts the gear box processing position again, and the roller 62 rolls the gear box processing position to ensure the size requirement of the gear box processing position.

[0066] The cooling device 7 includes: a second bracket 71 arranged on the shaft body 42, a mounting plate 72 arranged on the second bracket 71 and parallel to the gear box processing position, a sealing plate 73 bent on the mounting plate 72 and contacting the gear box processing position, and a nozzle 74 arranged on the mounting plate 72 and facing the gear box processing position.

[0067] A cooling space 75 is formed between the mounting plate 72 , the sealing plate 73 and the gearbox processing position. A nozzle 74 is disposed in the cooling space 75 .

[0068] One end of the sealing plate 73 is connected to the mounting plate 72, and the other end of the sealing plate 73 is curved in an arc and contacts the processing position of the gear box. The nozzle 74 is directed toward the other end of the sealing plate 73 and the processing position of the gear box respectively. The cooling process is carried out twice. The first time, the nozzle 74 sprays the cooling medium toward the other end of the sealing plate 73. The second time, the nozzle 74 sprays the cooling medium toward the processing position of the gear box.

[0069] During the first cooling process, the cooling device 7 moves along the gearbox processing position, and the other end of the sealing plate 73 contacts the gearbox processing position. The sealing plate 73 will shake during the movement of the cooling device 7. The temperature of the gearbox processing position is relatively high, and the temperature is transmitted to the other end of the sealing plate 73. After the gearbox processing position contacts the cooling medium, the cooling medium vaporizes rapidly, exacerbating the vibration of the sealing plate 73. Driven by the sealing plate 73, the cooling medium contacts the gearbox processing position for many times and vaporizes, causing the surface temperature of the gearbox processing position to drop rapidly.

[0070] During the second cooling process, the cooling device 7 moves along the gearbox processing position, and the cooling space 75 is not a sealed space. The amount of cooling medium sprayed by the nozzle 74 is greater than the amount of cooling medium leakage in the cooling space 75, and the cooling medium gradually fills most of the space in the cooling space 75. The gearbox processing position is immersed in the cooling medium, and the gearbox processing position is completely cooled.

[0071] When the vertical body 64 and the roller 62 act on the same processing position of the gear box in sequence, the gear box processing position is the through hole in the middle of the forged gear box. Due to the structural limitation of the through hole, it is impossible to act on both sides of the same processing position of the gear box, but the vertical body 64 and the roller 62 are used for processing in sequence.

[0072] The forging device 6 further includes: a first power device 66 , a swing plate 65 arranged to swing relative to each other, and a driving block 68 arranged at the driving end of the first power device 66 .

[0073] The roller 62 and the vibration device 63 are respectively arranged at one end of a swing plate 65 that swings relatively. A contact surface 67 is formed on both sides of the driving block 68, and the other end of the swing plate 65 contacts the contact surface 67.

[0074] The swing plate 65 is swingably arranged on the first bracket 61. Exemplarily, the first power device 66 is a hydraulic cylinder. The first power device 66 drives the driving block 68 to move back and forth, and the driving block 68 pushes the swing plate 65 to swing outward through the contact surface 67, and the swing plate 65 drives the vertical body 64 and the roller 62 to approach the gear box processing position.

[0075] A spring is arranged at the swinging position of the swinging plate 65, and the spring pushes the swinging plate 65 to swing inwards and reset, and the swinging plate 65 drives the vertical body 64 and the roller 62 away from the processing position of the gear box.

[0076] Since the through hole in the middle of the forging gear box is located inside the gear box, the heating device 5 , the forging device 6 and the cooling device 7 need to extend out of the driving shaft device 4 by a certain distance accordingly.

[0077] The driving shaft device 4 further includes: a first elastic device 45 , a moving rod 43 movably arranged on the shaft body 42 , a collar 44 rotatably sleeved on the shaft body 42 , and a second power device 46 arranged on the shaft body 42 .

[0078] The first elastic device 45 is respectively connected to the moving rod 43 and the shaft 42. The first elastic device 45 pulls the moving rod 43 to approach the collar 44. The edge of the collar 44 is provided with a protrusion 47, and the protrusion 47 extends toward the moving rod 43.

[0079] A gear is provided at the driving end of the second power device 46, and a tooth shape is formed around the collar 44, and the gear meshes with the tooth shape. The second power device 46 drives the collar 44 to rotate, and the moving rod 43 moves along the collar 44 and the protrusion 47 in sequence. When the moving rod 43 moves along the edge of the collar 44, the moving rod 43 does not extend out of the shaft body 42. When the moving rod 43 moves along the edge of the protrusion 47, the moving rod 43 extends out of the shaft body 42. By controlling the rotation angle of the collar 44, the moving rod 43 drives the heating device 5, the forging device 6 and the cooling device 7 to extend in sequence.

[0080] Figure 6The schematic diagram of the top view of the block mechanism of the gear box of the first embodiment of the present invention is shown, wherein the processing position of the gear box is the end faces at the left and right ends of the gear box. Figure 7 Shows Figure 6 Enlarged structural diagram of point A in the middle. Figure 8 Shows Figure 6 The enlarged structure diagram of B in the middle. Figure 1-Figure 11 As shown, the processing system of the high-precision gearbox further includes a block mechanism 8 for placing and recovering the cylindrical block. The block mechanism 8 includes: a third spring 85, a second spring 84, a second pressing plate 83, a first pressing plate 82 and a sleeve 81 arranged on the first bracket 61.

[0081] The two ends of the sleeve 81 are respectively an outlet and an inlet, and the two ends of the sleeve 81 are respectively facing the end surface mounting holes of the high-precision gearbox processing position. The cylindrical block is moved out of the sleeve 81 through the outlet, and the cylindrical block is placed in the end surface mounting hole of the high-precision gearbox processing position. The cylindrical block is moved out of the end surface mounting hole of the high-precision gearbox processing position, and the cylindrical block is moved into the sleeve 81 through the inlet.

[0082] The cylindrical blocks are arranged in parallel in the sleeve 81. The second spring 84 elastically pushes the first pressing plate 82, and the first pressing plate 82 pushes the cylindrical blocks to move into the end surface mounting holes of the high-precision gearbox processing position. The third spring 85 elastically pushes the second pressing plate 83, and the second pressing plate 83 presses the cylindrical blocks.

[0083] Exemplarily, the second spring 84 is a spring. Exemplarily, the third spring 85 is a spring. The second spring 84 and the first pressing plate 82 are installed at the outlet position in the sleeve 81, and the third spring 85 and the second pressing plate 83 are installed at the inlet position in the sleeve 81.

[0084] The inlet and outlet of the sleeve 81 are located at both ends of the sleeve 81, and the middle position of the sleeve 81 avoids the roller 62 from bending to a certain extent. The inlet and outlet of the sleeve 81 are located on both sides of the roller 62, so that the cylindrical block moves from the outlet of the sleeve 81 into the end face mounting hole. When the roller 62 rolls the high-precision gearbox processing position and the drop body 64 hammers the high-precision gearbox processing position through the end face mounting hole, the end face mounting hole is deformed near the end face mounting hole, and the size of the end face mounting hole is limited by the cylindrical block.

[0085] After the rolling of the roller 62 and the hammering of the pituitary body 64 are completed, the roller 62 continues to move and no longer contacts the cylindrical block, and the pituitary body 64 continues to move. However, due to the continuous hammering of the gear box processing position, the cylindrical block becomes loose, and then the cylindrical block is recovered by the sleeve 81.

[0086] The first pressing plate 82 is swingably arranged in the sleeve 81, and the second spring 84 is arranged at the swinging position of the first pressing plate 82, and the second spring 84 pushes the first pressing plate 82 to swing toward the outlet direction. When the outlet of the sleeve 81 approaches and connects with the end surface mounting hole, the second spring 84 pushes the first pressing plate 82 to swing, and the first pressing plate 82 pushes the cylindrical block near the outlet of the sleeve 81 to move out of the sleeve 81 and move into the end surface mounting hole.

[0087] The second pressing plate 83 is slidably disposed in the sleeve 81, and the third spring 85 pushes the second pressing plate 83 to press the cylindrical blocks in the arrangement direction. When a group of cylindrical blocks moves out of the sleeve 81, the third spring 85 extends to push the second pressing plate 83 to press the cylindrical blocks in the arrangement, so that the next group of cylindrical blocks moves closer to the outlet direction. When the cylindrical blocks move into the sleeve 81 from the inlet direction, the cylindrical blocks push the second pressing plate 83 to cause the third spring 85 to contract.

[0088] It takes a certain amount of time for the cylindrical block to move into the sleeve 81. In order to ensure that the roller 62 and the vertical body 64 can continue to move during the recovery process, an elastic paddle 86 is provided at the exit of the sleeve 81. As the cylindrical block gradually moves into the sleeve 81, the cylindrical block pushes the elastic paddle 86 to bend inward. After the cylindrical block moves into the sleeve 81, the elastic paddle 86 elastically returns to its original position outward, and the elastic paddle 86 shields the entrance of the sleeve 81.

[0089] Second embodiment: The processing technology of high-precision gearbox includes the following steps: Switching step: The third power device 16 drives the mounting table 12 to rotate a certain angle along the main table 11 through the meshing of the gear and the gear ring, and the gear box is switched to rotate and switch the two end positions. There are two sets of mounting tables 12 on the main table 11, so that the processing device 3 can continuously process the processing position of one end of each gear box, and the heating device 5, forging device 6 and cooling device 7 can continuously process the processing position of the other end of each gear box, so as to improve the processing efficiency of the gear box.

[0090] Forging steps: When the gearbox processing position is the end faces of the left and right ends of the gearbox: the shaft body 42 rotates a certain angle along the shaft seat 41 to drive the heating device 5 to the processing position. The driving device 2 drives the driving shaft device 4 and the heating coil 51 to move along the gearbox processing position. During the movement, the shaft body 42 rotates a certain angle along the shaft seat 41 so that the heating coil 51 always faces the gearbox processing position.

[0091] The shaft body 42 rotates a certain angle along the shaft seat 41 to drive the forging device 6 to the processing position. The driving device 2 drives the driving shaft device 4 and the forging device 6 to move along the gear box processing position. When the gear box processing position is the end face of the gear box, the shaft body 42 rotates a certain angle along the shaft seat 41 during the movement, so that the vertical body 64 and the roller 62 can act on both sides of the same processing position of the gear box at the same time.

[0092] When approaching the mounting hole of the end face during the movement, the second spring 84 elastically pushes the first pressing plate 82, and the first pressing plate 82 pushes the cylindrical block to move from the outlet of the sleeve 81 into the end face mounting hole of the high-precision gearbox processing position. The vertical body 64 and the roller 62 continue to move, and the inlet of the sleeve 81 approaches the end face mounting hole of the high-precision gearbox processing position. The cylindrical block pushes the elastic paddle 86 to bend inward, and after the cylindrical block moves into the sleeve 81, the elastic paddle 86 elastically resets outward. The third spring 85 elastically pushes the second pressing plate 83, and the second pressing plate 83 presses the cylindrical block.

[0093] When the processing position of the gear box is the through hole of the gear box, the shaft body 42 rotates continuously along the shaft seat 41, and the vertical body 64 and the roller 62 can also act on the same processing position of the gear box in sequence.

[0094] The drive shaft device 4 drives the cooling device 7 to the processing position, and the drive device 2 drives the drive shaft device 4 and the cooling device 7 to move along the gearbox processing position. The sealing plate 73 contacts the gearbox processing position, and the nozzle 74 sprays the cooling medium toward the sealing plate 73, and the cooling medium contacts the gearbox processing position multiple times. The nozzle 74 sprays the cooling medium toward the gearbox processing position, and the cooling medium gradually fills the cooling space 75, and the gearbox processing position is immersed in the cooling medium.

[0095] When the processing position of the gear box is the through hole in the middle of the gear box: the second power device 46 drives the ring 44 to rotate, the moving rod 43 moves along the ring 44 and the protrusion 47 in turn, and the moving rods 43 on the shaft 42 extend out in turn, and each moving rod 43 drives the heating device 5, the forging device 6 and the cooling device 7 to approach the through hole in the middle of the gear box.

[0096] The heating coil 51 on the moving rod 43 extends into the through hole at the middle position of the gear box for heating.

[0097] The first power device 66 on the moving rod 43 drives the driving block 68 to move, and the driving block 68 pushes the swinging plates 65 to swing closer to each other or away from each other. When the swinging plates 65 move away from each other, the roller 62 and the vibration device 63 are driven to approach the inner surface of the through hole in the middle of the gear box. After the shaft body 42 rotates, the vertical body 64 and the roller 62 can also act on the same processing position of the gear box in sequence. After the forging is completed, the swinging plates 65 move closer to each other, driving the roller 62 and the vibration device 63 away from the inner surface of the through hole in the middle of the gear box.

[0098] The cooling device 7 on the moving rod 43 extends into the gearbox processing position, the sealing plate 73 contacts the gearbox processing position, and the nozzle 74 sprays the cooling medium toward the sealing plate 73, and the cooling medium contacts the gearbox processing position multiple times. The nozzle 74 sprays the cooling medium toward the gearbox processing position, and the cooling medium gradually fills the cooling space 75, and the gearbox processing position is immersed in the cooling medium.

[0099] Machining steps: the drive shaft device 4 drives the processing device 3 to grind the gear box processing position.
