Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of gear hobbing machines, and in particular, to a CNC turbine gear hobbing machine. Background Art

[0002] A gear hobbing machine is a CNC machine tool specifically used for processing gear tooth profiles. Its core function is to achieve precise cutting of gear tooth profiles through the relative movement of the hob and the workpiece. It is a key equipment for gear processing in the field of mechanical manufacturing. During processing, the gear is installed on the positioning shaft, and then the hob spindle is driven by a motor, and the worm gear pair is used to reduce the speed to achieve low-speed rotation of the hob. The positioning shaft drives the gear to rotate, and then the hob cuts the tooth profile on the outside of the gear.

[0003] During the cutting process, the friction between the tool and the workpiece will generate a lot of heat, causing the temperature of the cutting area to rise. Therefore, it is necessary to spray cutting fluid on the parts in the cutting area during cutting, so that the parts absorb heat and heat up, and then drive the heat through flow. The cutting fluid after spraying will generally flow to the collection tank below, and the cutting fluid will flow out of the collection tank for collection, which is convenient for subsequent secondary use.

[0004] Because some metal debris will be generated during cutting, when the cutting fluid is sprayed, the cutting fluid will drive the debris to flow into the collection tank synchronously. When the cutting fluid is reused next time, the cutting fluid and the debris need to be collected synchronously and then filtered. After filtering, they are poured into the fluid storage tank of the gear hobbing machine for secondary use, which is more troublesome. Summary of the Invention

[0024] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0025] like Figures 1 to 7 As shown, it shows a CNC turbine gear hobbing machine in one embodiment of the present disclosure, including a gear hobbing machine body 1, a processing table of the gear hobbing machine body 1 is provided with a liquid leakage groove, and the bottom of the processing table is open, and also includes a liquid baffle plate 2, a liquid collecting box 3, a spray assembly, a chip dumping assembly and a reflux assembly. The liquid baffle plate 2 is detachably mounted on the processing table of the gear hobbing machine body 1, the liquid collecting box 3 is arranged below the processing table of the gear hobbing machine body 1 through a placement assembly, and a filter plate 29 is slidably installed in the liquid collecting box 3, the spray assembly is arranged at the top of the gear hobbing machine body 1, the chip dumping assembly is arranged on the side of the gear hobbing machine body 1, and is used to dump the filtered debris, and the reflux assembly is arranged on the side of the gear hobbing machine body 1, and is used to return the filtered cutting fluid to the spray assembly.

[0026] like Figure 4 and Figure 6As shown, when processing the gear, the gear is first placed on the positioning shaft, and then the CNC system controls the rotation of the tool on the gear hobbing machine body 1 to process the gear. During processing, the cutting fluid can be sprayed on the tool and gear through the spray assembly to reduce the temperature. The spray assembly includes a liquid storage tank 9, a delivery pump 10, a liquid outlet pipe 11 and a liquid spray plate 12. The liquid storage tank 9 is installed at the top of the gear hobbing machine body 1, and the delivery pump 10 is installed at the top of the gear hobbing machine body 1. A delivery pipe is installed between the delivery pump 10 and the liquid storage tank 9. The liquid outlet pipe 11 is connected to the outlet of the delivery pump 10, and the side of the gear hobbing machine body 1 A support rod supporting the liquid outlet pipe 11 is fixedly installed on the surface, and a liquid spray plate 12 is connected and installed on the liquid outlet pipe 11. Specifically, the delivery pump 10 is started, and the delivery pump 10 absorbs the cutting fluid in the liquid storage tank 9, so that the cutting fluid enters the delivery pump 10 through the delivery pipe, and then flows out through the liquid outlet pipe 11 to the liquid spray plate 12. The liquid spray plate 12 sprays the cutting fluid to the connection between the gear and the tool for cooling. Because both sides of the leakage groove of the gear hobbing machine body 1 are set to be arc-shaped, the sprayed cutting fluid can flow to the leakage groove and fall out. The liquid baffle plate 2 can block the cutting fluid, thereby preventing the cutting fluid from flowing to other places.

[0027] like Figure 2 As shown, before cutting, the liquid collecting box 3 can be placed under the leakage channel by placing the assembly, and the placing assembly includes a support platform 5, a fixing plate 6, a fixing block 7 and a fixing frame 8. There are two support platforms 5, and the two support platforms 5 are placed on the ground. The two support platforms 5 are located below the gear hobbing machine body 1, and the top of the support platform 5 is provided with a slide groove. The liquid collecting box 3 is slidably installed on the top of the support platform 5. The tops of the two support platforms 5 are fixedly installed with a fixing plate 6. Two fixing blocks 7 are fixedly installed on the side of the liquid collecting box 3, and the side of the fixing block 7 is provided with a groove that is connected to the fixing The plate 6 is adapted to the slot on the side, and the fixing frame 8 is detachably mounted on the top of the fixing block 7 and the fixing plate 6. Specifically, the support table 5 is placed under the gear hobbing machine body 1. It should be added that one end of the slide groove at the top of the support table 5 is open, so the collecting tank 3 can be slid into the slide groove of the support table 5 through the open end, and then slide forward to insert the fixing plate 6 into the slot of the fixing block 7, and then insert the fixing frame 8 into the top of the fixing block 7 and the fixing plate 6 to fix the collecting tank 3 on the support table 5, so that the flowing cutting fluid flows into the collecting tank 3.

[0028] like Figure 3 、 Figure 5 and Figure 7As shown, after the placement is completed, the filter plate 29 can be placed into the sump 3 through the scrap pouring assembly, which comprises a support cover one 13, a reciprocating screw rod 14, a first motor 15, a synchronous assembly and a rotating assembly. The support cover one 13 is fixedly installed on the side of the gear hobbing machine body 1. The reciprocating screw rod 14 is rotatably installed in the support cover one 13, and a matching sliding block 30 is installed on the reciprocating screw rod 14. The first motor 15 is installed on the support cover one 13, and the output end of the first motor 15 is coaxially connected with the reciprocating screw rod 14. The synchronous assembly is arranged on the side of the gear hobbing machine body 1. The rotating assembly is arranged on the sliding block 30 and the synchronous assembly. The synchronous assembly comprises a support cover two 16, a synchronous rod 17 and a synchronous block 18. The support cover two 16 is fixedly installed on the side of the gear hobbing machine body 1. The synchronous rod 17 is fixedly installed in the support cover two 16. The synchronous block 18 is slidably installed on the synchronous rod 17. The rotating assembly comprises a pulling rod 19, a rotating shaft 20, a connecting frame 21 and a driving assembly. The pulling rod 19 is fixedly installed on the bottom end of the synchronous block 18 and the reciprocating screw rod 14. The rotating shaft 20 is rotatably installed between the two pulling rods 19. The connecting frame 21 is fixedly installed between the rotating shaft 20 and the filter plate 29. The driving assembly is arranged on one of the pulling rods 19. The driving assembly comprises a second motor 22, a driving gear 23 and a driving gear ring 24. The second motor 22 is installed on one of the pulling rods 19. The driving gear 23 is coaxially connected with the output end of the second motor 22. The driving gear ring 24 is fixedly installed on the rotating shaft 20, and the driving gear 23 is engaged with the driving gear ring 24.

[0029] Specifically, the first motor 15 is started. The output end of the first motor 15 drives the reciprocating screw rod 14 to rotate in the support cover one 13, thereby driving the sliding block 30 to move on the reciprocating screw rod 14. Under the connection of the two pulling rods 19 and the rotating shaft 20, the filter plate 29 is driven to move forward, thereby being inserted into the sump 3. It should be noted that the size of the filter plate 29 is adapted to the size of the inside of the sump 3. Therefore, after being inserted, the side of the filter plate 29 can block the through slot on the side of the sump 3. The falling cutting fluid and the falling debris fall onto the filter plate 29. The filter plate 29 filters the debris. It should be noted that a plurality of filter holes for filtering debris are formed in the filter plate 29. Then, the filtered cutting fluid flows into the sump 3 below the filter plate 29.

[0030] When there are more debris on the filter plate 29, the first motor 15 can be started to drive the filter plate 29 to move in the opposite direction, so as to move out of the liquid collecting tank 3. After moving out completely, the second motor 22 is started, and the output end of the second motor 22 drives the driving gear 23 to rotate, the driving gear 23 drives the driving gear ring 24 engaged therewith to rotate, and the driving gear ring 24 drives the rotating shaft 20 to rotate, and the rotating shaft 20 drives the filter plate 29 to rotate in a small angle clockwise and counterclockwise under the connection of the connecting frame 21, so as to pour the debris on the ground. During pouring, a collection bucket can be placed on the ground to collect the debris. After pouring is completed, the filter plate 29 is rotated to a horizontal position, and then inserted into the liquid collecting tank 3 for subsequent filtering. The protective cover 28 is detachably installed on the rod 19, and the second motor 22, the driving gear 23 and the driving gear ring 24 are located in the protective cover 28, so as to protect the engagement of the driving gear 23 and the driving gear ring 24.

[0031] As shown in Figure 4 After filtering is completed, the cutting fluid in the liquid collecting tank 3 can be sucked into the liquid storage tank 9 through the backflow assembly 4 for secondary use. The backflow assembly 4 includes an oil pump 25, a backflow pipe 26 and an absorption pipe 27. The oil pump 25 is installed on the side of the gear hobbing machine body 1. The backflow pipe 26 is communicatively installed between the oil pump 25 and the liquid collecting tank 3. The absorption pipe 27 is communicatively installed between the oil pump 25 and the liquid storage tank 9. Specifically, the oil pump 25 is started, and the oil pump 25 sucks the cutting fluid in the liquid collecting tank 3 through the backflow pipe 26 into the absorption pipe 27, and then flows into the liquid storage tank 9. It needs to be supplemented that the backflow pipe 26 is communicatively installed on the side of the liquid collecting tank 3 through a flange.

[0032] Working principle: when the gear is processed and sprayed with cutting fluid, after the gear is installed, the support table 5 is placed below the gear hobbing machine body 1, the liquid collecting tank 3 is slid into the sliding groove of the support table 5 through the open end, and then slid forward, so that the fixed plate 6 is inserted into the insertion slot of the fixed block 7, and then the fixed frame 8 is inserted into the top end of the fixed block 7 and the fixed plate 6. The liquid collecting tank 3 is fixed on the support table 5, so that the flowing cutting fluid flows into the liquid collecting tank 3.

[0033] After the fixing is completed, the first motor 15 is started, the output end of the first motor 15 drives the reciprocating screw 14 to rotate in the support cover 13, thereby driving the sliding block 30 to move on the reciprocating screw 14, under the connection of the two pull rods 19 and the rotating shaft 20, the filter plate 29 is driven to move forward, thereby being inserted into the liquid collecting tank 3, the falling cutting fluid is communicated to fall into the filter plate 29, the filter plate 29 filters the debris, after the filtering is completed, if the debris on the filter plate 29 is more, the first motor 15 can be continuously started, thereby driving the filter plate 29 to move reversely, thereby moving out of the outside of the liquid collecting tank 3, after completely moving out, the second motor 22 is started, the output end of the second motor 22 drives the driving gear 23 to rotate, the driving gear 23 drives the driving gear ring 24 meshed therewith to rotate, the driving gear ring 24 drives the rotating shaft 20 to rotate, the rotating shaft 20 drives the filter plate 29 to overturn a small angle clockwise and counterclockwise under the connection of the connecting frame 21, thereby dumping the debris to the ground, after the dumping is completed, the filter plate 29 is rotated to the horizontal position, then it is inserted into the liquid collecting tank 3 to carry out subsequent filtering, finally the oil pump 25 is started, the oil pump 25 absorbs the cutting fluid in the liquid collecting tank 3 through the backflow pipe 26 to the absorption pipe 27 through the oil pump 25, then flows into the liquid storage tank 9 to carry out secondary utilization.
