Abstract

The present invention discloses a CNC machine tool loading robot with a lubrication mechanism, and the present invention relates to the field of robot technology. During the loading process of the robot, the robot arm rotates with the base. When the internal lubricating oil coating is uneven, it is easy to cause the robot to be subjected to greater wear during use, affecting the accuracy of use.

When the rotating ring rotates, the spiral groove drives the lubricating oil, so that the lubricating oil is evenly coated on the contact surface. At the same time, during the rotation process, the lubricating oil in the gap position moves, and when it rotates clockwise, the lubricating oil is driven to flow up, and when it rotates counterclockwise, the lubricating oil is driven to impact downward, so that the lubricating oil in the ring groove and the lubricating oil in the gap position can quickly exchange heat, ensuring lubrication while improving the cooling effect.

Technical Field

[0001] The invention relates to the technical field of manipulators, in particular to a CNC machine tool loading manipulator with a lubrication mechanism. Background Art

[0002] A manipulator is an automatic device that can mimic certain movements and functions of the human hand and arm, allowing it to grasp, move objects, or operate tools according to a fixed program. It can replace heavy human labor to achieve mechanization and automation of production, and can operate in hazardous environments to protect personal safety. It is widely used in sectors such as machinery manufacturing, metallurgy, electronics, light industry, and atomic energy. It consists of a hand, arm, and trunk. The hand is mounted on the front end of the arm and is used to grasp workpieces or tools. There are various structural forms such as clamping, holding, and suction types. The arm guides the fingers to accurately grasp the workpiece and transport it to the desired location. The trunk is the bracket for mounting the arm, power source, and various actuators.

[0003] During the loading process of the robot, the robot arm and the base rotate. If the internal lubricating oil coating is uneven, it is easy to cause the robot to suffer greater wear during use, affecting the accuracy of use. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0010] The bottom of the inner wall of the rotating groove is evenly provided with notches. Through the notches of the rotating groove, when wear occurs during the relative rotation between the rotating ring and the rotating groove, the worn debris particles slide downward during the rotation, and the notches provide a buffer space for the debris particles, thereby reducing the friction between the contact surface and avoiding increased wear due to accumulation of debris, while affecting the accuracy of the mechanical claw. An annular groove is provided at the center position of the bottom of the inner wall of the rotating groove, and the outer side of the rotating ring is rotatably adapted to the inner wall of the rotating groove, and the bottom of the rotating ring contacts the notches of the rotating groove. The outer side of the rotating ring is evenly provided with spiral grooves, and the spiral groove of the rotating ring cooperates with the annular groove of the rotating groove, so that the lubricating oil in the oil cover enters the annular groove through the conduit, and flows up to fill the rotating ring and the ring groove. When the grooves are in contact, the spiral groove drives the lubricating oil when the rotating ring rotates, so that the lubricating oil is evenly coated on the contact surface. At the same time, during the rotation process, the lubricating oil in the gap position moves, and the lubricating oil is driven to surge when rotating clockwise, and the lubricating oil is driven to impact downward when rotating counterclockwise, so that the lubricating oil in the annular groove and the lubricating oil in the gap position can quickly exchange heat, ensuring lubrication while improving the cooling effect. A third motor is fixedly installed on the inner wall of the top cover, and the output end of the third motor is flange-connected to the center position of the bottom of the top plate. An oil cover is fixedly installed on the top of the top cover, and the oil cover is located on the outside of the rotating groove. A conduit is fixedly installed between the oil cover and the rotating groove, and the end of the conduit close to the rotating groove is connected to the annular groove of the rotating groove.

A conical ring is fixedly installed on the outer side of the inner slide. The conical ring cooperates with the oil inlet and oil outlet holes, and utilizes the friction between the inner slide and the cylinder piston rod. During operation, when lubrication is required, the inner slide is driven to compress the rubber gasket, so that the conical ring moves, compressing the butter between the inner slide and the fixed cover, and at the same time blocking the oil inlet to ensure that the butter is discharged from the oil outlet and coated on the surface of the piston rod, thereby ensuring the lubrication effect of the cylinder. The conical ring is located on the side of the snap ring away from the rubber gasket, and the oil inlet hole of the fixed cover is located on the side of the snap ring away from the rubber gasket.

[0014] Preferably, the clamping mechanism includes a support block, which is fixedly mounted on the outside of the slider, and a zigzag plate is fixedly mounted on the outside of the support block, a rubber pad is fixedly mounted on the inner wall of the zigzag plate, and claw blocks are fixedly mounted on the tops of the opposite surfaces of the zigzag plates. The claw blocks are bent inward in an arc shape away from one end of the zigzag plate to cooperate with the rubber pad. While both ends of the material are subjected to clamping pressure, the arc-shaped clamping block is used to squeeze the material inward so that the material contacts the rubber pad, compressing the rubber pad to deform, so that the inner and outer sides of the material are also subjected to pressure. At the same time, the deformed rubber pad increases the contact area, increases friction, improves the fixing effect, ensures safety during loading and transportation, and prevents materials from slipping. The claw blocks are evenly mounted along the axial direction, and the claw blocks are bent inward in an arc shape away from one end of the zigzag plate.

[0015] The present invention provides a CNC machine tool loading robot with a lubrication mechanism. It has the following beneficial effects:

[0016] 1. The CNC machine tool loading robot with a lubrication mechanism cooperates with the spiral groove of the swivel and the ring groove of the rotating groove. When the lubricating oil in the oil cover enters the ring groove through the conduit and surges up to fill the contact between the swivel and the ring groove, the spiral groove drives the lubricating oil when the swivel rotates, so that the lubricating oil is evenly coated on the contact surface. At the same time, during the rotation process, the lubricating oil in the gap position moves, and the lubricating oil surges up when the rotation is clockwise, and the lubricating oil is driven downward when the rotation is counterclockwise, so that the lubricating oil in the ring groove and the lubricating oil in the gap position can quickly exchange heat, ensuring lubrication while improving the cooling effect.

[0017] 2. The CNC machine tool loading robot with a lubrication mechanism has a notch in the rotating groove. When wear occurs during the relative rotation between the rotating ring and the rotating groove, the worn debris particles slide downward during the rotation. The notch provides a buffer space for the debris particles, reducing the friction between the contact surface and avoiding increased wear due to debris accumulation, while affecting the accuracy of the mechanical claw.

[0018] 3. The CNC machine tool loading robot with a lubrication mechanism determines the lubrication status of the cylinder through the contact between the inner slide and the cylinder piston rod. During the clamping process, it determines the lubrication status of the cylinder through the friction between the piston rod and the inner slide, and performs synchronous lubrication when lubrication is needed, avoiding manual judgment and causing serious wear of the cylinder.

[0019] 4. The CNC machine tool loading robot with a lubrication mechanism cooperates with the oil inlet and oil outlet holes through the conical ring, and utilizes the friction between the inner slide and the cylinder piston rod. During the working process, when lubrication is needed, it drives the inner slide to compress the rubber gasket, so that the conical ring moves, compresses the butter between the inner slide and the fixed cover, and at the same time blocks the oil inlet to ensure that the butter is discharged from the oil outlet and coated on the surface of the piston rod to ensure the lubrication effect of the cylinder.

[0020] 5. The CNC machine tool loading robot with a lubrication mechanism bends the claw block inward in an arc shape away from one end of the zigzag plate, and cooperates with the rubber pad. While the two ends of the material are subjected to clamping pressure, the arc-shaped clamping block is used to squeeze the material inward, so that the material contacts the rubber pad, compressing the rubber pad to deform, and the inside and outside of the material are also subjected to pressure. At the same time, the deformed rubber pad increases the contact area, increases friction, and improves the fixing effect, thereby ensuring safety during loading and transportation and preventing the material from slipping.

The outer side of the swivel 10 is rotatably adapted to the inner wall of the rotating groove 9, and the bottom of the swivel 10 is in contact with the notch of the rotating groove 9. In the process of driving the top plate 7 to rotate by the third motor 6 to change the direction of the rotating arm mechanism 3, the top plate 7 rotates while driving the swivel 10 to rotate. The rotation adaptation of the swivel 10 and the rotating groove 9 is used to provide support and restriction for the rotation of the rotating arm mechanism 3. The outer side of the swivel 10 is evenly provided with spiral grooves. The inner wall of the top cover 2 is fixedly installed with the third motor 6. The output end of the third motor 6 is flange-connected to the center position of the bottom of the top plate 7. The top of the top cover 2 is fixedly installed with an oil cover 8. The oil cover 8 is fixedly installed on the top of the top cover 2. The cover 8 is located on the outside of the rotating groove 9. When the swivel 10 and the rotating groove 9 rotate relative to each other, the annular groove of the rotating groove 9 and the oil cover 8 are connected through the conduit 11, so that the liquid lubricating oil in the oil cover 8 is introduced into the annular groove of the rotating groove 9 by the conduit 11, and rises in the annular groove of the rotating groove 9 to fill the gap between the rotating groove 9 and the swivel 10. At the same time, in conjunction with the rotation of the swivel 10, the spiral groove on the outside of the swivel 10 is used to fill the spiral groove when stationary. During the rotation, the spiral groove drives the lubricating oil so that the lubricating oil is evenly coated on the gap between the contact surface of the swivel 10 and the rotating groove 9. A conduit 11 is fixedly installed between the oil cover 8 and the rotating groove 9. The end of the conduit 11 close to the rotating groove 9 is connected to the annular groove of the rotating groove 9.

[0040] The swivel arm mechanism 3 includes a fixed block 32, which is fixedly mounted at the center position of the top of the top plate 7, and a swivel arm 33 is rotatably mounted on the inner wall of the fixed block 32, and a first motor 31 is fixedly mounted on the outer side of the fixed block 32, and the output end of the first motor 31 passes through the fixed block 32 and is fixedly connected to the inner wall of the swivel arm 33. A groove is provided at one end of the swivel arm 33 away from the fixed block 32 and is fixedly connected to the fixed block 32 through the top plate 7. During the rotation process, the first motor 31 cooperates with the second motor 34 to drive the swivel arm 33 to rotate, thereby controlling the angle between the swivel arm 33 and the fixed block 32, and cooperating with the second motor 34 to drive the forearm 35 to rotate, thereby controlling the angle between the swivel arm 33 and the forearm 35, thereby driving the clamping mechanism 4 to move, controlling the clamping angle and the clamping position, and the forearm 35 is rotatably mounted on the groove of the swivel arm 33, and a second motor 34 is fixedly mounted on the outer side of the swivel arm 33, and the output end of the second motor 34 is fixedly connected to the inner wall of the forearm 35.

[0041] The second embodiment, based on the first embodiment, see Figures 7 and 8As shown, the clamping mechanism 4 includes a connecting plate 41, which is fixedly mounted on one end of the forearm 35 away from the rotating arm 33, and a guide rail 43 is fixedly mounted on the side of the connecting plate 41 away from the forearm 35. The guide rail 43 is symmetrically mounted along the center position of the axis of the connecting plate 41, and a slider 42 is slidably mounted between the guide rails 43, and the slider 42 is driven by the cylinder 44 to move under the restriction of the guide rail 43. In the process of clamping the object, the cylinder 44 drives the slider 42 to approach each other, so that the clamping claw mechanism 5 approaches each other to clamp the object. At the same time, in the process of the cylinder 44 driving the slider 42 to move, the inner slide 46 contacts the surface of the piston rod of the cylinder 44, and the slider 42 is symmetrically mounted between the guide rails 43. The cylinder 44 is fixedly mounted at the corners of the connecting plate 41 away from the forearm 35.

[0042] The output end of the cylinder 44 is fixedly connected to the two ends of the slider 42, and the outer side of the connecting plate 41 is fixedly installed with a connecting block 47, and the outer side of the connecting block 47 is fixedly installed with a fixed cover 45. The inner wall of the fixed cover 45 is slidably installed with an inner slide 46, and the inner slide 46 contacts the surface of the piston rod of the cylinder 44. The inner wall of the inner slide 46 is evenly provided with oil outlet holes, and the outer side of the fixed cover 45 is provided with an oil inlet hole, and the inner wall of the fixed cover 45 is provided with a snap ring. During the operation of the cylinder 44, when the lubricating grease on the surface of the piston rod is reduced, the friction between the piston rod and the inner slide 46 increases. When the piston rod extends and drives the sliders 42 to approach each other, the inner slide 46 is driven to move by friction, pressing The rubber gasket 49 is deformed and, during the movement of the inner slide 46, the conical ring 48 is driven to move together. During the movement, the butter between the inner slide 46 and the fixed cover 45 is squeezed. At the same time, during the movement, the conical ring 48 blocks the oil inlet hole of the fixed cover 45, so that the butter is discharged from the oil outlet hole of the inner slide 46. During the movement of the piston rod of the cylinder 44, the butter is coated on the surface of the piston rod for lubrication. A rubber gasket 49 is fixedly installed between the retaining ring and the inner slide 46, and a conical ring 48 is fixedly installed on the outside of the inner slide 46. The conical ring 48 is located on the side of the retaining ring away from the rubber gasket 49, and the oil inlet hole of the fixed cover 45 is located on the side of the retaining ring away from the rubber gasket 49.

[0043] The third embodiment, based on the first and second embodiments, see Figures 9 and 10As shown, the clamping mechanism 5 includes a support block 51, which is fixedly mounted on the outer side of the slider 42, and a zigzag plate 53 is fixedly mounted on the outer side of the support block 51. Through the connection between the support block 51 and the slider 42, when the sliders 42 approach each other, the support blocks 51 are driven to approach each other. In the process of approaching, the zigzag plates 53 are driven to approach each other, and the claw blocks 54 on the opposite sides of the zigzag plates 53 contact the material. The inner wall of the zigzag plate 53 is fixedly mounted with a rubber pad 52, and the tops of the opposite sides of the zigzag plates 53 are fixedly mounted with claw blocks 54. The arc bending of the claw blocks 54 is used to drive the material to approach the rubber pad 52 during the clamping process, so that the material is clamped and pressurized at both ends. At the same time, the arc shape of the claw blocks 54 and the rubber deformation of the rubber pad 52 are used to make the inner and outer sides of the material receive clamping pressure at the same time, thereby ensuring the fixing effect. The claw blocks 54 are evenly mounted along the axial direction, and the end of the claw block 54 away from the zigzag plate 53 is curved inward.

[0044] When in use, it is supported by the base 1, and the top plate 7 is driven to rotate by the third motor 6 to change the clamping direction of the rotating arm mechanism 3. At the same time, the rotating arm mechanism 3 controls the clamping angle, and the clamping mechanism 4 is coordinated to approach the material to be loaded. The clamping mechanism 4 drives the clamping claw mechanism 5 to approach each other to clamp the loaded material, and the loading and transportation are carried out with the cooperation of the third motor 6 and the rotating arm mechanism 3.

[0045] When the third motor 6 drives the top plate 7 to rotate and changes the direction of the rotating arm mechanism 3, the top plate 7 rotates and drives the swivel 10 to rotate at the same time. The rotation adaptation of the swivel 10 and the rotating groove 9 is used to provide support and restriction for the rotation of the rotating arm mechanism 3. When the swivel 10 and the rotating groove 9 rotate relative to each other, the annular groove of the rotating groove 9 and the oil cover 8 are connected through the conduit 11, so that the liquid lubricating oil in the oil cover 8 is introduced into the annular groove of the rotating groove 9 by the conduit 11, and flows up in the annular groove of the rotating groove 9 to fill the gap between the rotating groove 9 and the swivel 10. At the same time, in conjunction with the rotation of the swivel 10, the spiral groove on the outside of the swivel 10 is used to fill the lubricating oil into the spiral groove when it is stationary. During the rotation, the spiral groove drives the lubricating oil so that the lubricating oil is evenly coated on the gap between the contact surface of the swivel 10 and the rotating groove 9.

[0046] In the rotating arm mechanism 3, it is fixedly connected to the fixed block 32 through the top plate 7. During the rotation process, the first motor 31 cooperates with the second motor 34. The first motor 31 drives the rotating arm 33 to rotate, controls the angle between the rotating arm 33 and the fixed block 32, and cooperates with the second motor 34 to drive the forearm 35 to rotate, controls the angle between the rotating arm 33 and the forearm 35, drives the clamping mechanism 4 to move, and controls the clamping angle and clamping position.

[0047] When the piston rod of the cylinder 44 moves, the inner slide 46 is in contact with the surface of the piston rod, and when the piston rod is in operation, the friction between the piston rod and the inner slide 46 increases. When the piston rod extends and drives the sliders 42 to move closer to each other, the friction force drives the inner slide 46 to move, and the compression rubber gasket 49 is deformed. At the same time, when the inner slide 46 moves, the conical ring 48 is driven to move together. During the movement, the butter between the inner slide 46 and the fixed cover 45 is squeezed. At the same time, during the movement, the conical ring 48 blocks the oil inlet hole of the fixed cover 45, so that the butter is discharged from the oil outlet hole of the inner slide 46. During the movement of the piston rod of the cylinder 44, the butter is coated on the surface of the piston rod for lubrication.

[0048] In the clamping mechanism 5, through the connection between the support block 51 and the slider 42, when the sliders 42 approach each other, the support blocks 51 are driven to approach each other, and in the process of approaching, the zigzag plates 53 are driven to approach each other, and the claw blocks 54 on the opposite sides of the zigzag plates 53 contact the material, and the curved bending of the claw blocks 54 is used to drive the material to approach the rubber pad 52 during the clamping process, so that the material is clamped and pressurized at both ends, and the curved shape of the claw blocks 54 and the rubber deformation of the rubber pad 52 are used to make the inner and outer sides of the material receive clamping pressure at the same time, thereby ensuring the fixing effect.
