[0032] See also Figure 1 and Figure 2 , which are respectively a stereogram and another stereogram of the automatic loading gear hobbing machine of the present embodiment; as shown in the figure, the automatic loading gear hobbing machine of the present invention comprises a frame 1 and a gear hobbing device 2, a tooth blank feeding device 3, a tooth blank pushing device 4, a tooth blank clamping and feeding device 5 and a deburring device 6 arranged on the frame 1, wherein the gear hobbing device 2 is used to process the tooth blank into a finished tooth piece, the tooth blank feeding device 3 is used to load and transport the tooth blank to be processed, the tooth blank pushing device 4 is used to push the tooth blank conveyed by the tooth blank feeding device 3 to the tooth blank clamping and feeding device 5, the tooth blank clamping and feeding device 5 is used to clamp and transport the tooth blank pushed into place to the gear hobbing device 2 for processing, and the deburring device 6 removes burrs of the tooth blank while the gear hobbing device 2 is processing, so that it forms a smooth tooth piece.

[0033] For more information, see Figure 3, which is a schematic diagram of a gear hobbing device in an embodiment; as shown in the figure, the gear hobbing device 2 includes a gear blank fixing mechanism 21, a gear blank pressing mechanism 22 and a hobbing mechanism 23, the gear blank fixing mechanism 21 and the gear blank pressing mechanism 22 are arranged opposite to each other at intervals, and the hobbing mechanism 23 is located on one side between the gear blank fixing mechanism 21 and the gear blank pressing mechanism 22. The gear blank fixing mechanism 21 includes a hydraulic cylinder 211, a first hydraulic motor 212 and a fixing rod 213. The hydraulic cylinder 211 can perform horizontal pushing motion, the first hydraulic motor 212 is connected to the output end of the hydraulic cylinder 211, and the fixing rod 213 is connected to the output end of the first hydraulic motor 212. The first hydraulic motor 212 is driven to move horizontally through the hydraulic cylinder 211, and the first hydraulic motor 212 drives the fixing rod 213 to rotate; the fixing rod 213 is used to pass through multiple gear blanks to be processed, and an axial hole is provided in the middle of the gear blank. Preferably, the fixing rod 213 is a stepped rod, the diameter of the thinner section of the stepped rod is smaller than the diameter of the axial hole of the tooth embryo, so as to facilitate rapid insertion into the axial hole of the tooth embryo, and the diameter of the thicker section of the stepped rod is larger than the diameter of the axial hole of the tooth embryo, thereby limiting the position of the tooth embryo and preventing the tooth embryo from moving along the fixing rod 213. The tooth embryo clamping mechanism 22 includes a second hydraulic motor 221 and a clamping rod 222, the clamping rod 222 is connected to the output end of the second hydraulic motor 221 and is arranged opposite to the fixing rod 213, and the clamping rod 222 is driven by the second hydraulic motor 221 to rotate and operate. When the tooth embryo to be processed is sleeved on the thinner section of the fixing rod 213, the hydraulic cylinder 211 drives the tooth embryo to move horizontally until it abuts and clamps against the end of the clamping rod 222, so as to prevent the tooth embryo from moving axially along the fixing rod. The roller cutter mechanism 23 includes a third hydraulic motor 231 and a roller cutter 232 . The roller cutter 232 is mounted on the output shaft of the third hydraulic motor 231 and is located on one side between the clamping rod 222 and the fixing rod 213 . The roller cutter 232 is driven to rotate by the third hydraulic motor 231 .

[0034] For further information, see Figure 4 , which is a schematic diagram of the tooth embryo feeding device in the embodiment; as shown in the figure, the tooth embryo feeding device 3 includes a vibration feeding mechanism 31. Preferably, the vibration feeding mechanism 31 is a vibration plate, which effectively reduces its occupied space through the circular vibration plate, and extends its transportation track, which is convenient for controlling the feeding speed. The output end 311 of the vibration feeding mechanism 31 outputs the tooth embryos to be processed one by one in an orderly manner.

[0035] For further information, see Figure 5, which is a schematic diagram of the tooth embryo pushing device in this embodiment; as shown in the figure, the tooth embryo pushing device 4 is located on one side of the feeding device 3, and includes a pushing cylinder 41 and a pushing block 42. The output direction of the pushing cylinder 41 corresponds to the vibration feeding mechanism 31 of the tooth embryo feeding device 3, and the pushing block 42 is arranged at the output end of the pushing cylinder 41, and the pushing block 42 is moved to the output end of the vibration feeding mechanism 31 through the output end 311 of the pushing cylinder 41. In detail, a tooth embryo groove 421 and a photoelectric sensor 422 are provided on the side of the pushing block 42 adjacent to the output end 311 of the vibration feeding mechanism 31. When the output end 311 of the vibration feeding mechanism 31 sends out the tooth embryo, the output end of the pushing cylinder 41 drives the pushing block 42 to move to dock with the tooth embryo, and the tooth embryo falls into the tooth embryo groove 421 accordingly. The output end 311 of the vibration feeding mechanism 31 continuously outputs the tooth embryo, and the pushing cylinder 41 continuously moves back and forth, pushing multiple tooth embryos one by one to the clamping and feeding tooth embryo device 5. The photoelectric sensor 422 senses and monitors the movement times of the pusher block 42, so that the pusher cylinder 41 moves according to the set times, thereby pushing a specified number of tooth blanks to the tooth blank clamping and feeding device 5. Preferably, the tooth blank groove 421 of the pusher block 42 is a circular hole, and its diameter corresponds to the diameter of the tooth blank to be processed. When the tooth blank product to be processed is replaced, the pusher block 42 can also be disassembled and replaced so that the size of its tooth blank groove 421 corresponds to the tooth blank.

[0036] For further information, see Figure 6, which is a schematic diagram of the tooth blank clamping and conveying device in the embodiment; as shown in the figure, the tooth blank clamping and conveying device 5 is located on one side of the output end 311 of the tooth blank pushing device 4 and the vibrating feeding mechanism 31, and includes a feeding cylinder 51 and a pneumatic clamp 52. The pneumatic clamp 52 is arranged at the output end of the feeding cylinder 51 and corresponds to the pushing block 42. The output direction of the feeding cylinder 51 corresponds to the hob mechanism 23. When the feeding cylinder 51 is operated, the pneumatic clamp 52 is immediately transferred to the hob mechanism 23. In detail, when the pushing block 42 of the tooth blank pushing device 4 is pushed to the output end 311 of the vibrating feeding mechanism 31, the pushing block 42 is also correspondingly moved to the seamlessly adjacent side of the pneumatic clamp 52. At this time, the pneumatic clamp 52 is in an open state, the tooth embryo groove 421 of the push block 42 is adjacent to the clamping opening 521 of the pneumatic clamp 52, and the push block 42 pushes the tooth embryos one by one to the clamping opening 521 of the pneumatic clamp 52, and the size of the clamping opening 521 of the pneumatic clamp 52 also corresponds to the size of the tooth embryo. Preferably, a stopper 522 is provided on the other side of the clamping opening 521 of the pneumatic clamp 52, and the stopper 522 prevents the tooth embryo from being pushed out of the clamping opening 521 and falling. In order to improve production efficiency, the push cylinder pushes continuously 3 to 8 times, and pushes 3 to 8 tooth embryos to be processed to the clamping opening 521 of the pneumatic clamp 52, so that the pneumatic clamp 52 clamps multiple tooth embryos at the same time. At the same time, the photoelectric sensor 422 monitors the number of pushes in real time to ensure that the tooth embryo pushing device 4 operates according to the set number of times. When the push cylinder 41 operates for the set number of times, the push cylinder 41 returns to its original position and stops operating. Correspondingly, the pneumatic clamp 52 closes and clamps the multiple tooth blanks to be processed in the clamping jaws 521. The feeding cylinder 51 is started, and its output end drives the pneumatic clamp 52 to move between the tooth blank fixing mechanism 21 and the tooth blank clamping mechanism 22, so that the tooth blank to be processed moves to correspond to the hob mechanism 23, and the axial hole of the tooth blank corresponds to the fixing rod 213.

[0037] In the actual production process, firstly, the tooth blank feeding device 3, the tooth blank pushing device 4 and the tooth blank clamping device 5 are used to sequentially complete the loading, pushing, feeding and positioning of the above-mentioned tooth blanks. After completion, the hydraulic cylinder 211 of the tooth blank fixing mechanism 21 of the gear hobbing device 2 is started, driving the first hydraulic motor 212 and the fixing rod 213 to move closer to the tooth blank until one end of the fixing rod 213 penetrates into the axial hole of the tooth blank, and the tooth blank is abutted and pressed against the pressing rod 222 of the tooth blank pressing mechanism 22, and the hydraulic cylinder 211 stops moving, and the tooth blank is fixed. At this time, the pneumatic clamp 52 of the tooth blank clamping device 5 releases the tooth blank and returns to the original position. Then the deburring device 6 is started. The deburring device 6 includes a knife feeding cylinder 61 and a deburring tool 62. The knife feeding cylinder 61 is installed on the side of the hobbing mechanism 23 and is located below the tooth blank, saving space and facilitating access to the tooth blank. The deburring tool 62 is installed at the output end of the knife feeding cylinder 61. When the hob mechanism 23 is started, the knife feeding cylinder 61 is started, and its output end is extended, raising the height of the deburring tool 62 to the height of the tooth embryo and bringing it close to the tooth embryo. When the deburring tool 62 is in place, the hob mechanism 23 is started, and the hob 232 rotates to process the tooth embryo. At the same time, the first hydraulic motor 212 and the second hydraulic motor 221 respectively drive the fixing rod 213 and the clamping rod 222 to rotate synchronously, that is, drive the tooth embryo to rotate synchronously, so that it adapts to the rotation speed of the hob 232. When the tooth embryo rotates and rolls, the burrs protruding from the surface of the tooth embryo are scraped off by friction with the deburring tool 62.

[0038] After the gear hobbing device 2 processes the tooth blank into a finished tooth piece, the hobbing mechanism 23 stops running, the first hydraulic motor 212 and the second hydraulic motor 221 also stop running, the tooth piece stops rotating, the tool feeding cylinder 61 of the deburring device 6 drives the deburring tool 62 to return to the original position, the hydraulic cylinder 211 of the tooth blank fixing mechanism 21 moves and returns to the original position, the fixing rod 213 is then pulled out of the axial hole of the tooth piece, the tooth piece loses its fixation, and freely falls to the storage frame below (not shown in the figure), and after a certain number of finished products are processed, the storage frame is taken out.

[0039] While the gear hobbing device is processing, the tooth embryo delivery device 3, the tooth embryo pushing device 4 and the tooth embryo clamping device 5 are restarted, and the tooth embryo pushing device 4 pushes the tooth embryos to be processed one by one into the pneumatic clamping jaws 52 of the tooth embryo clamping device 5 for clamping. When the gear hobbing device 2 removes the processed tooth pieces, the above processing steps are repeated, and the processing time is fully utilized and the processing efficiency is improved. Correspondingly, optionally, when the pusher block 42 is replaceable according to the size of the tooth embryo, the pneumatic clamping jaw 52 can also be disassembled and replaced accordingly, so that its clamping mouth 521 matches the tooth embryo, which is convenient for clamping the tooth embryo.

[0040] Preferably, the automatic feeding gear hobbing machine of the present invention further comprises a detachable support base plate 7, which is arranged on the surface of the frame 1, and the tooth embryo feeding device 3, the tooth embryo pushing device 4 and the tooth embryo clamping device 5 are respectively arranged on the support base plate 7, and the tooth embryo feeding device 3, the tooth embryo pushing device 4 and the tooth embryo clamping device 5 can be integrally disassembled or transferred through the support base plate 7. When the gear hobbing machine used by the user only has the gear hobbing device 2, the above-mentioned devices can be installed on the gear hobbing device 2 through the support base plate 7, so as to realize the diversification of functions, improve the working efficiency, and do not damage the original body, and occupy a small space.

[0041] To summarize, the automatic loading gear hobbing machine of the present invention loads materials through the gear blank feeding device, the gear blank pushing device pushes the loaded multiple gear blanks one by one to the clamping and feeding gear blank device, the clamping and feeding gear blank device clamps and transfers the multiple gear blanks to the gear hobbing device for positioning and processing, and a deburring device is used to remove burrs at the same time. The gear hobbing machine of the present invention realizes rapid feeding and processing through the cooperation of the above-mentioned mechanisms, and the various devices operate in coordination to improve production efficiency. In addition, some jigs can be disassembled and replaced, which is suitable for processing gear blanks of various sizes and has a wide range of applications.
