Description

Technical Field

[0001] This invention relates to the field of gear processing technology, specifically to a hobbing cutter-based fixed gear forming and processing platform. Background Technology

[0002] Gear hobbing is a widely used gear machining process based on the generating method. It is mainly used for machining spur and helical cylindrical gears, and can also machine worm gears, sprockets, etc. When using a special hob, it can also machine splines, sprockets, and other workpieces with special tooth profiles. There are two common hobbing machine specifications for gear hobbing: one where the workpiece is fixed and the hob continuously moves towards the workpiece to achieve hobbing, and the other where the hob is fixed in position and the workpiece continuously moves towards the hob to achieve hobbing. However, in the hobbing device with a fixed hob, the workpiece needs to be placed on the positioning pin and then locked with a nut. After hobbing, it is inconvenient to remove the gear, which affects the efficiency of subsequent gear machining. Moreover, cutting fluid needs to be continuously sprayed on the machining area during hobbing. The cutting fluid mixed with metal chips needs to be recycled and reused. Traditional machining devices first collect the waste cutting fluid, then filter it, and then reuse the waste cutting fluid for the next hobbing operation. Based on this, we propose a machining platform that can improve the efficiency of gear machining. Summary of the Invention

This method can effectively improve the feeding efficiency of the blank. The drive motor drives the connecting shaft to rotate, which causes the blank to rotate. Under the action of the single-acting screw motor linear module, the vertical frame drives the clamping mechanism to move towards the gear hobbing cutter, thereby allowing the gear hobbing cutter to perform gear hobbing on the blank. During the processing, the spraying component continuously sprays cutting fluid onto the cutting area, while the waste cutting fluid flows into the recovery tank through the outlet. The recovery component continuously filters and recovers the waste cutting fluid, thereby improving the utilization efficiency of the cutting fluid. After the gear hobbing is completed, the box door is opened, and the linear module of the single-acting lead screw motor drives the clamping component to extend out of the processing box. Then, the clamping mechanism releases the clamping and fixing of the gear, and the indexing plate in the first clamping component descends, allowing the operator to quickly remove the gear and replace it with a new blank, thereby improving the gear hobbing efficiency.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1 - Figure 9This invention provides a technical solution: a hobbing cutter fixed gear forming processing platform, including a worktable 1, a processing box 2 installed on the top of the worktable 1, a box door 3 installed on the front of the processing box 2, the top of the worktable 1 being fixedly connected to the fixed end of a rotating disk 4, the rotating end of the rotating disk 4 being fixedly connected to one end of a hobbing cutter 5 by an interference fit, a support frame 6 being fixedly installed on the top of the worktable 1, a drive motor 7 being fixedly connected to the top of the support frame 6, the output shaft of the drive motor 7 being fixedly connected to a clamping head 8, the clamping head 8 being fixedly connected to the other end of the hobbing cutter 5, the drive motor 7 extending to the outside of the top of the processing box 2, a clamping mechanism 9 for clamping and fixing the blank being fixedly connected to one side of the top of the worktable 1, a fixed platform 10 being fixedly connected to the other side of the top of the worktable 1, and a spraying assembly 11 for lubricating and cooling the hobbing cutter 5 being fixedly connected to the top of the fixed platform 10.

[0020] In this embodiment, the clamping mechanism 9 includes a single-acting lead screw motor linear module 12 fixedly installed on the top of the workbench 1. A vertical frame 13 is fixedly connected to the moving surface of the single-acting lead screw motor linear module 12. A crossbeam 14 is fixedly connected to the top of one side of the vertical frame 13. A double-acting bidirectional lead screw motor linear module 15 is fixedly connected to the bottom end of the crossbeam 14. A first clamping assembly 16 and a second clamping assembly 17 are fixedly connected to the two moving surfaces of the bidirectional lead screw motor linear module 15, respectively. The blank is clamped and fixed between the first clamping assembly 16 and the second clamping assembly 17. The hobbing cutter 5 is located directly behind the first clamping assembly 16 and the second clamping assembly 17. A liquid outlet 18 penetrating the workbench 1 is opened on one side of the workbench 1. A liquid collection hopper is installed at the bottom end of the workbench 1 at the liquid outlet 18. A recovery assembly 19 for recovering cutting fluid is installed at the bottom end of the workbench 1.

[0021] Specifically, the bidirectional lead screw motor linear module 15 can synchronously control the first clamping assembly 16 and the second clamping assembly 17 to move towards or away from each other. After clamping and fixing the gear blank between the first clamping assembly 16 and the second clamping assembly 17, the single-acting lead screw motor linear module 12 drives the vertical frame 13 to move towards the hobbing cutter 5, and the drive motor 7 drives the hobbing cutter 5 to rotate, so that the hobbing cutter 5 can perform hobbing on the blank. By directly using the first clamping assembly 16 and the second clamping assembly 17 to clamp and fix the blank, compared with the prior art, it has the advantages of fast blank loading rate and fast removal of the processed gear. During the processing, the spraying assembly 11 continuously sprays cutting fluid onto the cutting part of the hobbing cutter 5 to lubricate and cool it. The cutting fluid mixed with metal chips flows into the bottom recycling assembly 19 through the outlet 18, so that the processing platform can filter and recycle the waste cutting fluid during the gear hobbing process, thereby improving the waste cutting fluid recycling efficiency.

[0022] In this embodiment, the first clamping assembly 16 includes a first connecting plate 161 fixedly mounted on the surface of one of the moving parts of the bidirectional lead screw motor linear module 15. A servo motor 162 is fixedly connected to the bottom end of the first connecting plate 161. A vertical plate 163 is provided on one side of the servo motor 162. A first slide rail 164 is fixedly connected to the surface of the vertical plate 163. A first slider 165 is slidably mounted on the surface of the first slide rail 164. A first mounting plate 166 is fixedly connected to the surface of the first slider 165. A bearing seat 167 with a built-in bearing is mounted on the surface of the vertical plate 163. An adjusting lead screw 168 is rotatably connected inside the bearing seat 167. One end of the adjusting screw 168 is fixedly connected to the output shaft of the servo motor 162. A screw nut is fixedly installed on the back of the first mounting plate 166. The screw nut is connected to the adjusting screw 168. An indexing plate 169 is installed on the front of the first mounting plate 166. A connecting column 1610 is clamped and fixed inside the indexing plate 169. A limit plate 1611 is integrally provided on the surface of the connecting column 1610. The blank is sleeved and installed on the connecting column 1610. Four guide rods 20 are fixedly connected to one side of the vertical frame 13. Guide holes 21 are opened at the four corners of the vertical plate 163. The guide rods 20 are inserted and installed in the corresponding guide holes 21.

[0023] Specifically, the connecting column 1610 is clamped and fixed by the indexing plate 169. The blank is inserted into the connecting column 1610 and one end of the blank is tightly pressed against the limiting plate 1611. This method makes blank loading and unloading easier and effectively improves gear processing efficiency. When the bidirectional lead screw motor linear module 15 drives the first connecting plate 161 to move, the guide rod 20 and guide hole 21 can improve the stability of the lateral movement of the first clamping assembly 16. The operator can replace the connecting column 1610 of different sizes according to the needs of processing different specifications of gears, so that the blank can be stably moved. The gear is fitted onto the connecting column 1610, thereby improving the practicality of the processing platform. After the gear is processed, the single-acting lead screw motor linear module 12 drives the vertical frame 13 to move towards the outside of the processing box 2. Then, the servo motor 162 drives the adjusting lead screw 168 to rotate. Under the action of the lead screw nut, the first mounting plate 166 is raised and lowered. The stability of the first mounting plate 166 is improved by the action of the first slide rail 164 and the first slider 165. Therefore, the indexing plate 169 can be lowered, which makes it convenient for the staff to quickly remove the gear that has been processed on the surface of the connecting column 1610.

[0024] In this embodiment, the second clamping assembly 17 includes a second connecting plate 171 fixedly installed on another power surface of the bidirectional lead screw motor linear module 15. A support 172 is fixedly installed at the bottom end of the second connecting plate 171. A connecting shaft 173 is rotatably installed at the bottom end of the support 172. A driven synchronous pulley 174 is fixedly connected to one end of the connecting shaft 173. A clamping cup 175 is fixedly connected to the other end of the connecting shaft 173. An annular skirt 176 is embedded in the middle of the clamping cup 175 and extends outward at the end. A motor bracket 177 is fixedly connected to one side of the support 172. A power motor 178 is fixedly connected to one side of the motor bracket 177. The output shaft of the power motor 178 is fixedly connected to the active synchronous pulley 179. A synchronous belt 1710 is installed between the active synchronous pulley 179 and the driven synchronous pulley 174.

[0025] Specifically, when the bidirectional lead screw motor linear module 15 synchronously drives the first connecting plate 161 and the second connecting plate 171 to move towards each other, the clamping cup 175 and the connecting post 1610 will approach each other, and one end of the connecting post 1610 will be inserted into the clamping cup 175 and the annular skirt 176 will be in close contact with the surface of the blank. Thus, the blank can be clamped under the action of the annular skirt 176 and the limiting plate 1611. The power motor 178 drives the active synchronous pulley 179 to rotate, and under the action of the synchronous belt 1710, the driven synchronous pulley 174 drives the connecting shaft 173 to rotate, which in turn drives the clamping cup 175 to rotate. In this way, the blank is rotated to perform gear hobbing.

[0026] In this embodiment, the spraying assembly 11 includes a base 111 fixedly installed on the top of the fixed platform 10. A support plate 112 is fixedly connected to the top of the base 111. A mounting bracket 113 is fixedly connected to the top of the support plate 112. An electric push rod 114 is fixedly connected to the top of the mounting bracket 113. A second slide rail 115 is fixedly connected to one side of the mounting bracket 113. A second slider 116 is slidably installed on the surface of the second slide rail 115. A second mounting plate 117 is fixedly connected to the surface of the second slider 116. A plurality of nozzles 118 for spraying cutting fluid are fixedly installed on the surface of the second mounting plate 117. The nozzles 118 are positioned directly opposite the gear hobbing cutter 5. A connecting rod is fixedly connected to the telescopic end of the electric push rod 114. A connecting plate 119 is fixedly connected to the bottom end of the connecting rod. A limiting groove 1110 is opened at the top of the second mounting plate 117. A through groove is opened at the top of the limiting groove 1110. The connecting plate 119 is inserted into the limiting groove 1110 and the connecting rod is disposed in the through groove.

[0027] Specifically, the electric push rod 114, in conjunction with the connecting plate 119, can adjust the height of the second mounting plate 117. The second slide rail 115, in conjunction with the second slider 116, can stabilize the lifting and lowering of the second mounting plate 117. Adjusting the height of the second mounting plate 117 allows for adjustment of the height of the nozzle 118, thereby enabling the cutting fluid sprayed from the nozzle 118 to be continuously sprayed onto the gear hobbing area.

[0028] In this embodiment, the recycling assembly 19 consists of a recycling tank 22, a metal filter 23, a recycling pump 24, and a recycling pool 25. The top of the recycling tank 22 is open, and the recycling tank 22 is located directly below the liquid collection hopper. A first connecting pipe connects the recycling tank 22 and the metal filter 23. A second connecting pipe connects the metal filter 23 and the recycling pump 24. A third connecting pipe connects the recycling pump 24 and the recycling pool 25. An output pump 26 is also installed in the recycling pool 25. A fourth connecting pipe connects the output pump 26 and the nozzle 118. The recycling tank 22, the metal filter 23, and the recycling pump 24 are all fixedly installed at the bottom of the workbench 1, and the recycling pool 25 is located outside the workbench 1.

[0029] Specifically, waste cutting fluid flows into the collection hopper through the outlet 18, and then into the recovery tank 22. The recovery pump 24 forces the cutting fluid through the metal filter 23 for filtration, thereby filtering out metal debris. The filtered cutting fluid is then pumped to the recovery pool 25 by the recovery pump 24, and the output pump 26 pumps the cutting fluid from the recovery pool 25 to the nozzle 118 for spraying. In this way, the machining platform can simultaneously recover and filter the cutting fluid when performing gear hobbing, thereby improving the efficiency of cutting fluid recycling.

[0030] In this embodiment, the bottom of the recycling bin 22 is provided with wedge-shaped slopes 221 on both sides. A discharge port is provided on one side of the recycling bin 22, and a sealing plug 222 is installed at the discharge port. A discharge groove 223 is installed on the side of the recycling bin 22 at the discharge port.

[0031] Specifically, when the processing platform stops working, the cutting fluid mixed with metal chips in the recovery box 22 will begin to stratify under the action of gravity. The metal chips will be deposited at the bottom of the recovery box 22. Under the action of the slope 221, the metal chips will slowly be deposited at the lower part of the slope 221. After opening the sealing plug 222, the deposited metal chips can be discharged. The metal chips will be discharged through the discharge trough 223 and collected in a centralized manner.

[0032] In this embodiment, a third slide rail 27 is fixedly connected to the bottom end of the vertical frame 13, and a third slider 28 is fixedly connected to the bottom end of the third slide rail 27. The third slider 28 is fixedly installed on the top of the worktable 1. When the single-acting lead screw motor linear module 12 works until the actuator reaches its maximum stroke, the first clamping assembly 16 and the second clamping assembly 17 are located outside the processing box 2.

[0033] Specifically, by setting the third slider 28, the vertical frame 13 can be supported, so that the clamping mechanism 9 can work stably. When the single-acting lead screw motor linear module 12 is working, under the action of the third slide rail 27 and the third slider 28, the clamping mechanism 9 can be stably transported to the outside of the processing box 2, which makes it easier for the staff to remove the processed gear and replace the new blank, effectively improving the gear processing efficiency.

[0034] In this embodiment, a first photoelectric switch 29 and a second photoelectric switch 30 are fixedly connected to one side of the upright plate 163, and a sensing plate 31 is fixedly connected to the side of the first slider 165. The first photoelectric switch 29 is located on top of the second photoelectric switch 30. When the first photoelectric switch 29 detects the sensing plate 31, the axis of the indexing plate 169 is coaxial with the axis of the clamping cup 175.

[0035] Specifically, when the servo motor 162 drives the adjusting screw 168 to rotate, causing the first mounting plate 166 to lower the first slider 165, the servo motor 162 stops working when the second photoelectric switch 30 detects the sensing plate 31. Then, after the worker removes the gear machined on the surface of the connecting column 1610 and replaces it with a new blank, the external PLC controller controls the servo motor 162 to drive the adjusting screw 168 to rotate in the opposite direction, causing the first slider 165 to rise until the first photoelectric switch 29 detects the sensing plate 31. Since the axis of the indexing plate 169 is coaxial with the axis of the clamping cup 175 at this time, when the bidirectional screw motor linear module 15 works, causing the first clamping assembly 16 and the second clamping assembly 17 to move towards each other, the clamping cup 175 can stably clamp the blank.

[0036] In this embodiment, protective covers for preventing and blocking debris are installed on the bottom of the single-acting lead screw motor linear module 12, the bidirectional lead screw motor linear module 15, the vertical plate 163, the support plate 112, and the vertical frame 13. The protective covers are not shown in the accompanying drawings.

[0037] Specifically, since a large amount of flying metal debris is generated during gear hobbing, the protective cover can effectively protect the single-acting lead screw motor linear module 12, the bidirectional lead screw motor linear module 15, as well as the first slide rail 164, the second slide rail 115, and the third slide rail 27.

[0038] The contents not described in detail in this description are existing technologies known to those skilled in the art. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
