[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0033] Reference Figure 1 and Figure 2 A cutting device for processing bearing rings includes a base 1, with baffles 2 vertically fixed on both sides of the upper surface of the base 1, a turret 3 is installed on the top of one of the baffles 2, and two sets of clamps 4 are slidably fitted on the top of the other baffle 2, and a rail carrier 401 is installed on the baffle 2 to drive the two sets of clamps 4 to move horizontally.
[0034] When machining bearing rings, fixture 4 holds the workpiece in place. The electric spindle drives fixture 4 to rotate, driving the workpiece. At this point, the position of turret 3 is adjusted, allowing the tool on turret 3 to cut the workpiece. After machining is complete, track carrier 401 drives fixture 4 to move, removing the machined workpiece from its workstation. Another set of fixtures 4, carrying the workpiece, then moves to the workstation to begin machining the bearing rings.
[0035] When the clamp 4 drives the processed workpiece to move away from the work station, the clamp 4 will open, allowing the processed workpiece to be unloaded under the action of gravity.
[0036] A rotating shaft 6 is rotatably installed on the inner walls of the two baffles 2, one end of the rotating shaft 6 is fixedly connected to a V-belt pulley 5, and the other end of the rotating shaft 6 is fixedly connected to an incomplete gear 8. A support plate 9 is fixedly connected to the bottom of the incomplete gear 8 to carry a transfer box 901, and the transfer box 901 is used to collect the processed workpieces. A short shaft 7 is rotatably installed on the baffle 2, and a driven gear 27 is fixedly connected to the shaft body of the short shaft 7. The driven gear 27 cooperates with the incomplete gear 8, and a long connecting plate 10 is fixedly connected to the end of the short shaft 7. A connecting piece 20 is fixedly connected to the bottom of the long connecting plate 10 to fix the guide plate 21. Connecting shafts 28 are rotatably installed on both sides of the guide plate 21, and a buffer plate 22 is fixedly connected to the shaft body of the connecting shaft 28. A support spring 26 is provided between the guide plate 21 and the buffer plate 22 to balance the gravity of the buffer plate 22.
[0037] During the unloading process of the workpiece, the diesel engine drives the V-belt pulley 5 to deflect a certain angle through the V-belt, the V-belt pulley 5 drives the rotating shaft 6 to rotate synchronously, and the rotating shaft 6 drives the support plate 9 to rotate. After the support plate 9 rotates, the transfer box 901 will also deflect.
[0038] After the transfer box 901 is deflected, the workpieces inside it are gathered on the lower side under the action of gravity, while the higher side is left empty.
[0039] During the rotation of the rotating shaft 6, the incomplete gear 8 on its shaft body will also rotate accordingly. The rotation of the incomplete gear 8 will drive the driven gear 27 to rotate, and the rotation of the driven gear 27 will drive the long connecting plate 10 to rotate. During the rotation of the long connecting plate 10, the guide plate 21 at the bottom will be deflected, and the deflection direction of the guide plate 21 is opposite to the deflection direction of the transfer box 901. After the guide plate 21 is deflected, its bottom will always point to the empty side inside the transfer box 901.
[0040] Therefore, when unloading, the workpiece will be guided by the guide plate 21 and will fall on the empty side inside the transfer box 901. When the workpiece falls into the transfer box 901, it will not collide with the workpiece in the box, thereby preventing the workpiece from having a rigid impact with the workpiece in the box during unloading, and preventing the workpiece from being damaged and deformed due to the impact force.
[0041] like Figure 3 and Figure 4 As shown, the top of the long connecting plate 10 is connected to a cover plate 12 through an elastic support structure, and the cover plate 12 covers the top opening of the transfer box 901 to prevent cutting chips from falling into the box.
[0042] The long connecting plate 10 drives the cover plate 12 to rotate, causing the cover plate 12 to tilt. When the cover plate 12 tilts, the cutting chips falling on the cover plate 12 will slide down under the action of gravity, thereby completing the cleaning of the cutting chips on the cover plate 12.
[0043] like Figure 4-Figure 6As shown, the elastic support structure includes a sliding sleeve 13 and a connecting block 17. The sliding sleeve 13 is fixed on both sides of the cover plate 12, and the connecting block 17 is fixed on the top of the long connecting plate 10. A sliding rod 14 is fixed through the long connecting plate 10, and the sliding sleeve 13 is slidably fitted on the sliding rod 14. A return spring 15 is provided on the sliding rod 14 to apply elastic force to the sliding sleeve 13.
[0044] like Figure 7-Figure 17 As shown, the first racks 16 are fixedly connected to both sides of the bottom surface of the cover plate 12, the first gear 11 is installed on the end of the short shaft 7, the first pulley 23 is fixed to the end face of the first gear 11, the second gear 18 is rotatably installed on the bottom of the long connecting plate 10, the second pulley 25 is fixed to the end face of the second gear 18, the first pulley 23 and the second pulley 25 are transmitted by a belt 24, the second racks 19 are slidably fitted on both sides of the guide plate 21, the second rack 19 matches the second gear 18, and the friction wheels 29 are fixed to both ends of the connecting shaft 28, and the friction wheels 29 rest on the second rack 19.
[0045] After the cover 12 is tilted, the sliding sleeve 13 will be driven to slide on the sliding rod 14 under the action of gravity and compress the reset spring 15. During the sliding process of the cover 12, the first rack 16 will be driven to move synchronously. During the movement of the first rack 16, the first gear 11 will be driven to rotate on the short shaft 7. The rotation of the first gear 11 will drive the first pulley 23 to rotate. The rotation of the first pulley 23 will drive the second pulley 25 to rotate through the belt 24. After the second pulley 25 rotates, it will drive the second gear 18 to rotate. The rotation of the second gear 18 will drive the second rack 19 to move on the guide plate 21. The movement of the second rack 19 will drive the friction wheel 29 to rotate. The rotation of the friction wheel 29 will The connecting shaft 28 is driven to rotate. After the connecting shaft 28 rotates, the buffer plates 22 on both sides of the guide plate 21 will be deflected by a certain angle. The direction of deflection of the buffer plates 22 is opposite to the direction of rotation of the guide plates 21, thereby reducing the angle between the buffer plates 22 and the horizontal direction, reducing the slope of the buffer plates 22, and making the buffer plates 22 flatter. When the workpiece falls vertically on the buffer plates 22 due to gravity, compared with a large angle with a steeper slope, the buffer plates 22 with a smaller slope can better buffer the impulse in the vertical direction of the workpiece, so as to reduce the speed at which the workpiece falls into the transfer box 901, and further improve the protection capability of the device during the workpiece unloading process.
[0046] Working principle:
[0047] Reference Figure 18When machining bearing rings, fixture 4 holds the workpiece in place. The electric spindle drives fixture 4 to rotate, driving the workpiece. At this point, the position of turret 3 is adjusted, allowing the tool on turret 3 to cut the workpiece. After machining is complete, track carrier 401 drives fixture 4 to move, removing the machined workpiece from its workstation. Another set of fixtures 4, carrying the workpiece, moves to the workstation to begin machining the bearing rings.
[0048] When the clamp 4 drives the processed workpiece to move away from the work station, the clamp 4 will open, allowing the processed workpiece to be unloaded under the action of gravity.
[0049] During the unloading process of the workpiece, the diesel engine drives the V-belt pulley 5 to deflect a certain angle through the V-belt, the V-belt pulley 5 drives the rotating shaft 6 to rotate synchronously, and the rotating shaft 6 drives the support plate 9 to rotate. After the support plate 9 rotates, the transfer box 901 will also deflect.
[0050] After the transfer box 901 is deflected, the workpieces inside it are gathered on the lower side under the action of gravity, while the higher side is left empty.
[0051] During the rotation of the rotating shaft 6, the incomplete gear 8 on its shaft body will also rotate accordingly. The rotation of the incomplete gear 8 will drive the driven gear 27 to rotate, and the rotation of the driven gear 27 will drive the long connecting plate 10 to rotate. During the rotation of the long connecting plate 10, the guide plate 21 at the bottom will be deflected, and the deflection direction of the guide plate 21 is opposite to the deflection direction of the transfer box 901. After the guide plate 21 is deflected, its bottom will always point to the empty side inside the transfer box 901.
[0052] Therefore, when unloading, the workpiece will be guided by the guide plate 21 and will fall on the empty side inside the transfer box 901. When the workpiece falls into the transfer box 901, it will not collide with the workpiece in the box, thereby preventing the workpiece from having a rigid impact with the workpiece in the box during unloading, and preventing the workpiece from being damaged and deformed due to the impact force.
[0053] The long connecting plate 10 drives the cover plate 12 to rotate, causing the cover plate 12 to tilt. When the cover plate 12 tilts, the cutting chips falling on the cover plate 12 will slide down under the action of gravity, thereby completing the cleaning of the cutting chips on the cover plate 12.
[0054] After the cover 12 is tilted, the sliding sleeve 13 will be driven to slide on the sliding rod 14 under the action of gravity and compress the reset spring 15. During the sliding process of the cover 12, the first rack 16 will be driven to move synchronously. During the movement of the first rack 16, the first gear 11 will be driven to rotate on the short shaft 7. The rotation of the first gear 11 will drive the first pulley 23 to rotate. The rotation of the first pulley 23 will drive the second pulley 25 to rotate through the belt 24. After the second pulley 25 rotates, it will drive the second gear 18 to rotate. The rotation of the second gear 18 will drive the second rack 19 to move on the guide plate 21. The movement of the second rack 19 will drive the friction wheel 29 to rotate. The rotation of the friction wheel 29 will The connecting shaft 28 is driven to rotate. After the connecting shaft 28 rotates, the buffer plates 22 on both sides of the guide plate 21 will be deflected by a certain angle. The direction of deflection of the buffer plates 22 is opposite to the direction of rotation of the guide plates 21, thereby reducing the angle between the buffer plates 22 and the horizontal direction, reducing the slope of the buffer plates 22, and making the buffer plates 22 flatter. When the workpiece falls vertically on the buffer plates 22 due to gravity, compared with a large angle with a steeper slope, the buffer plates 22 with a smaller slope can better buffer the impulse in the vertical direction of the workpiece, so as to reduce the speed at which the workpiece falls into the transfer box 901, and further improve the protection capability of the device during the workpiece unloading process.
[0055] Compared with the existing technology, when unloading, the workpiece of this device will be guided by the guide plate and will fall on the empty side inside the transfer box. When the workpiece falls into the transfer box, it will not collide with the workpiece in the box, thereby preventing the workpiece from having a rigid impact with the workpiece in the box during unloading, and preventing the workpiece from being damaged and deformed due to the impact force.
[0056] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
