Description

Technical Field

[0002] The turning and grinding machine is a multifunctional machining equipment that can complete both turning and grinding processes on a single machine, thereby improving machining efficiency and production flexibility.

[0003] Chinese Patent Publication No. CN117047562A provides an invention patent for a turning and grinding machine and a processing technology for CNC machining. The present invention uses a screw structure to control a shaft transmission structure, and controls an arc cleaning table through the shaft transmission structure, so that the waste generated by grinding and cutting enters different liquid collection chambers through different liquid inlets, which is conducive to the subsequent recycling of two different mixed waste liquids. The purpose of the above-mentioned device is to classify and collect grinding debris and cutting debris, but in actual work, both cutting debris and grinding debris need to pass through the arc cleaning table to enter different liquid inlets and then flow into different collection pools. Therefore, when the cutting work is completed, there will be some cutting debris on the arc cleaning table. When it is converted to grinding work, the cutting debris on the arc cleaning table will follow the grinding debris into the grinding debris collection pool, and finally the grinding debris collection pool is mixed with cutting debris, and the purpose of classified collection is not achieved.

[0019] Example like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, a turning and grinding machine for mechanical processing includes a turning and grinding component 1, a workpiece bearing component 2 for bearing a workpiece is provided below the turning and grinding component 1, a fixing component 3 is provided on the workpiece bearing component 2, the fixing component 3 is used to support annular workpieces with different fixed radii, a discharge component 4 is provided below the workpiece bearing component 2, the discharge component 4 is used to separately collect turning chips and grinding chips, wherein the workpiece bearing component 2 includes a disc-shaped bucket 21, a partition 22 is fixedly connected inside the disc-shaped bucket 21, the partition 22 evenly divides the disc-shaped bucket 21 into two left and right areas, and processing tables 24 for placing the workpiece are respectively provided on both sides of the partition 22, and the processing table 24 is rotatably connected to the disc-shaped bucket 21 through a support column 23; A tooth 25 is provided at the lower end of the processing table 24 , and a gear 26 is provided on one side of the processing table 24 . The gear 26 is meshed with the tooth 25 . The gear 26 is fixedly connected to the output shaft of the second motor 27 . The second motor 27 is fixedly connected in the partition 22 .

[0020] In the embodiment, after the annular workpiece 99 is fixed on the processing table 24, the No. 2 motor 27 is started, and the No. 2 motor 27 drives the gear 26 to rotate. The gear 26 drives the processing tables 24 on both sides to rotate through the teeth 25. At this time, the annular workpiece 99 follows the rotation. At this time, the turning and grinding assembly 1 can turn and grind two annular workpieces 99 at the same time. At the same time, the turning and grinding debris follows the cooling water flow to the disc bucket 21. The partition 22 divides the disc bucket 21 into two areas, one is the turning area, and the other is the grinding area, and the debris from different areas are collected separately.

[0021] like Figure 1 and Figure 6 As shown, the turning and grinding assembly 1 includes a machine table 11, and a pair of frames 12 are symmetrically arranged on the upper end surface of the machine table 11, a No. 1 motor 13 is fixedly connected to one side of the frame 12, and a bidirectional screw rod 14 is fixedly connected to the output end of the No. 1 motor 13, and the bidirectional screw rod 14 is rotatably connected between the two frames 12, and a back plate 16 is provided on one side of the bidirectional screw rod 14, and the back plate 16 is fixedly connected between the two frames 12, and a pair of driving blocks 15 are threadedly connected to the bidirectional screw rod 14, and the driving blocks 15 and the back plate 16 are slidably connected; A turning head 17 is fixedly connected to the lower end of the driving block 15 close to the No. 1 motor 13 , and a grinding head 18 is fixedly connected to the lower end of the driving block 15 away from the No. 1 motor 13 .

[0022] In the embodiment, after the circular ring workpiece 99 is fixed, the No. 1 motor 13 is started to drive the bidirectional screw 14 to rotate, and the bidirectional screw 14 drives the driving block 15 to move toward the circular ring workpiece 99. Finally, the driving block 15 drives the turning head 17 and the grinding head 18 to fit the circular ring workpiece 99 to be processed respectively, and then the circular ring workpiece 99 rotates to start the turning and grinding processing.

[0023] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, the fixing assembly 3 includes an air collecting pipe 31, which is fixedly connected to the back plate 16 by a bracket, and the left and right ends of the air collecting pipe 31 are slidably connected to a No. 1 piston 33, and a sliding rod 34 is fixedly connected to the No. 1 piston 33, and the sliding rod 34 extends out of the air collecting pipe 31. The two No. 1 pistons 33 are fixedly connected by a supporting spring 32, and the air collecting pipe 31 is located on the movement path of the driving block 15; The middle of the gas collecting pipe 31 is fixedly connected with an air guide pipe 35, and the air guide pipe 35 extends to the bottom of the disc-shaped bucket 21 and is divided into an air outlet pipe 38 and an air intake pipe 42. A one-way valve is provided on the air outlet pipe 38. An air collecting cavity 36 is provided inside the processing table 24. The air outlet pipe 38 passes through the support column 23 and is connected to the air collecting cavity 36 through a rotating sealing joint. A plurality of external expansion units 37 are provided on the periphery of the air collecting cavity 36. The outward expansion unit 37 includes a slide 371, and the slide 371 is opened inside the processing table 24. One end of the slide 371 is connected to the air collecting chamber 36. A No. 2 piston 372 is slidably connected in the slide 371. A push rod 373 is fixedly connected to the end of the No. 2 piston 372 away from the air collecting chamber 36. The end of the push rod 373 extends out of the slide 371 and is fixedly connected to the outward expansion rod 374. A slide groove 375 is opened on the processing table 24. The outward expansion rod 374 is slidably connected to the slide groove 375. The outward expansion rod 374 is used to fix the annular workpiece 99.

[0024] In the embodiment, when the left and right driving blocks 15 approach the annular workpiece 99, the driving blocks 15 push the sliding rods 34 at both ends of the gas collecting pipe 31, and the sliding rods 34 drive the No. 1 piston 33 to slide in the gas collecting pipe 31 and compress the support spring 32, and the gas in the gas collecting pipe 31 is compressed into the air guide pipe 35, and the air guide pipe 35 inputs the air into the outlet pipe 38. The one-way valve on the outlet pipe 38 can only discharge air but not take in air, and the gas is passed from the outlet pipe 38 to the gas collecting chamber 3 6, the gas in the gas collecting chamber 36 gathers and pushes the No. 2 piston 372 to slide in the slide 371. When the No. 2 piston 372 slides, the push rod 373 pushes the expansion rod 374 to slide and expand outward in the slide groove 375. Then, the expansion rod 374 contacts the inner side of the annular workpiece 99 (after the expansion rod 374 contacts and is subjected to force, the pressure valve 39 discharges the excess gas in the air outlet pipe 38 to maintain a stable pressure), completing the fixation of the annular workpiece 99.

[0025] like Figure 1 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, a one-way valve is provided on the suction pipe 42, a collecting pipe 41 is fixedly connected to the bottom of the disc-shaped bucket 21, a collecting chamber 44 is fixedly connected to the lower end surface of the machine 11, a partition plate 45 is fixedly connected in the collecting chamber 44, the partition plate 45 divides the collecting chamber 44 into two parts, one end of the two collecting pipes 41 away from the disc-shaped bucket 21 extends into the collecting chamber 44, and the suction pipe 42 extends into the collecting chamber 44 and is fixedly connected to the partition plate 45; The collecting pipe 41 is located at the end of the collecting chamber 44 and is provided with a fixed pipe 43. The end of the fixed pipe 43 is fixedly connected to the suction pipe 42. A sliding column 410 is slidably connected in the fixed pipe 43. The end of the sliding column 410 away from the suction pipe 42 is fixedly connected to a connecting column 411. The connecting column 411 is slidably connected to the fixed pipe 43. The end of the connecting column 411 away from the sliding column 410 is fixedly connected to a dredging wire rope 47. The dredging wire rope 47 is provided with a plurality of protrusions. The wire rope 47 extends out of the fixed pipe 43, and the dredging wire rope 47 is slidably connected in the collecting pipe 41. A return spring 46 is embedded in the connecting column 411, and one end of the return spring 46 is fixedly connected to the end of the sliding column 410 away from the suction pipe 42, and the other end of the return spring 46 is fixedly connected to the end of the fixed pipe 43 away from the suction pipe 42. An air passage 48 is provided in the sliding column 410, and an exhaust hole 49 is provided on the fixed pipe 43, and the air passage 48 and the exhaust hole 49 cooperate with each other. The disc-shaped bucket 21 has an inclined bottom surface, and the collecting pipe 41 and the disc-shaped bucket 21 are connected at a relatively low position, so as to facilitate the discharge of cooling water and debris.

[0026] In the embodiment, after turning and grinding are completed, the driving block 15 drives the turning head 17 and the grinding head 18 to reset away from the circular workpiece 99. At this time, the sliding rod 34 is no longer subjected to the pressure of the driving block 15, so the supporting spring 32 stretches to drive the No. 1 piston 33 to slide. At this time, the air guide pipe 35 inhales air. Since the air outlet pipe 38 can only exhaust air but not intake air, the air intake pipe 42 inhales air from the outside (the one-way valve on the air intake pipe 42 can only intake air but not exhaust air). Since the collecting pipe 41 is used to discharge water and debris, the debris is easily stuck in the collecting pipe 41 and causes blockage, so the suction force of the air intake pipe 42 is transmitted to the fixed pipe 43, so that the fixed pipe 43 is under negative pressure, and the sliding column 410 in the fixed pipe 43 slides toward the air intake pipe 42. When the sliding column 410 slides, it drives the connecting column 411 to pull the dredging wire rope 47 to move in the collecting pipe 41, thereby clearing the debris blocked in the collecting pipe 41. When the sliding column 410 slides, the reset spring 46 will be stretched. During the continuous sliding process of the sliding column 410, the airway 48 and the exhaust hole 49 are in contact. At this time, the negative pressure state of the fixed tube 43 disappears temporarily, and the reset spring 46 contracts, driving the sliding column 410 to reset, and the unblocking wire rope 47 is also reset. At the same time, the airway 48 and the exhaust hole 49 are no longer in contact. With the continuous suction of the suction pipe 42, the fixed tube 43 forms a negative pressure state again, and the sliding column 410 slides again to drive the connecting column 411 and the unblocking wire rope 47 to move in the collecting pipe 41, forming a continuous back and forth pulling of the unblocking wire rope 47 in the collecting pipe 41 (the number of pulling times depends on the amount of suction of the collecting pipe 31), further improving the efficiency of unblocking, and then the water and debris in the collecting pipe 41 are collected in the collecting chamber 44, and the isolation plate 45 separates the turning chips and grinding chips to achieve the function of classified collection.

[0027] The workflow is as follows: First, the circular workpiece 99 to be turned or polished is placed on the processing table 24, and then the No. 1 motor 13 is started. The No. 1 motor 13 drives the turning head 17 and the polishing head 18 to gradually approach the circular workpiece 99 through the bidirectional screw 14. During this process, the driving block 15 will first push the sliding rod 34 to move. The sliding rod 34 drives the No. 1 piston 33 to slide in the air collecting pipe 31, and the air in the air collecting pipe 31 is filled into the air guide pipe 35, and the air is filled into the air guide pipe 35. In the air collecting chamber 36, the air in the air collecting chamber 36 eventually pushes the No. 2 piston 372 to drive the push rod 373 to slide in the slide 371, and the push rod 373 drives the outward expansion rod 374 to slide and expand outward in the slide groove 375 on the processing table 24. Finally, the outward expansion rod 374 contacts the inner side of the circular workpiece 99 to complete the fixation of the circular workpiece 99. After that, the turning head 17 and the grinding head 18 still gradually approach the circular workpiece 99. At this time, the gas filled into the outlet pipe 38 will be discharged from the pressure valve 39. During the turning and grinding process, the debris will follow the cooling water from the collecting pipe 41 into the collecting chamber 44, and the collecting chamber 44 will be separated by the isolation plate 45, so that the turning chips and grinding chips can be classified and collected. When the turning and grinding are completed, the driving block 15 drives the turning head 17 and the grinding head 18 to reset away from the annular workpiece 99. At this time, the sliding rod 34 is no longer subjected to the pressure of the driving block 15, so the supporting spring 32 extends and drives the No. 1 piston 33 to slide. At this time, the air guide pipe 35 inhales air, and the suction pipe 42 transmits the suction force to the fixed pipe 43, so that the sliding column 410 in the fixed pipe 43 slides toward the suction pipe 42. When the sliding column 410 slides, it drives the connecting column 411 to pull the dredging wire rope 47 to move in the collecting pipe 41, thereby clearing the debris blocked in the collecting pipe 41.
