Description

Technical Field

[0001] The present invention relates to the technical field of manipulators, and specifically to a numerically controlled machine tool loading manipulator with a lubrication mechanism. Background Technique

[0002] A manipulator is an automatic operating device that can imitate some action functions of human hands and arms, and grab, transport objects or operate tools according to a fixed program. It can replace heavy human labor to achieve production mechanization and automation, and can operate in harmful environments to protect personal safety. It is widely used in departments such as machinery manufacturing, metallurgy, electronics, light industry, and atomic energy. It includes a hand, an arm, and a torso. The hand is installed at the front end of the arm and is used to hold workpieces or tools. There are various structural forms such as clamping type, supporting type, and adsorption type. The function of the arm is to guide the fingers to accurately grasp the workpiece and transport it to the required position. The torso is a bracket for installing the arm, power source, and various actuating mechanisms;

[0003] During the process of loading the manipulator, when the mechanical arm rotates with the base and the internal lubricating oil coating is uneven, it is easy to cause greater wear of the manipulator during use, affecting the use accuracy. Summary of the Invention

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

[0005] A numerically controlled machine tool loading manipulator with a lubrication mechanism, comprising:

[0006] A base, on the top of which a top cover is installed. On the top of the top cover, a rotating groove is installed. At the top of the rotating groove, a rotating ring is rotatably installed. At the top of the rotating ring, a top plate is fixedly installed;

[0007] A rotating arm mechanism, which is used to control the clamping direction and is installed on the top of the top plate;

[0008] A clamping mechanism, which is used to apply pressure for clamping and is installed at one end of the rotating arm mechanism away from the top plate;

[0009] A jaw mechanism, which is installed outside the clamping mechanism;

[0010] The bottom of the inner wall of the rotating groove is evenly provided with missing grooves. Through the missing grooves 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 rotation. The missing grooves provide a buffer space for the debris particles, reducing the friction with the contact surface, avoiding increased wear caused by debris accumulation, and affecting the accuracy of the mechanical claw at the same time. And a ring groove is provided at the center position of the bottom of the inner wall of the rotating groove. The outer side of the rotating ring is rotationally adapted to the inner wall of the rotating groove, and the bottom of the rotating ring is in contact with the missing groove of the rotating groove. The outer side of the rotating ring is evenly provided with spiral grooves. Through the cooperation of the spiral grooves of the rotating ring 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 rotating ring and the ring groove, the spiral grooves drive 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 rotation, the lubricating oil at the gap position moves. When rotating clockwise, it drives the lubricating oil to surge up, and when rotating counterclockwise, it drives the lubricating oil to impact downward, enabling the lubricating oil in the ring groove to quickly exchange heat with the lubricating oil at the gap position, ensuring lubrication and improving the cooling effect at the same time. A third motor is fixedly installed on the inner wall of the top cover. 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. The oil cover is located outside the rotating groove, and a conduit is fixedly installed between the oil cover and the rotating groove. One end of the conduit close to the rotating groove is communicated with the ring groove of the rotating groove.

[0011] Preferably, the rotating arm mechanism includes a fixed block. The fixed block is fixedly installed at the center position of the top of the top plate. And a rotating arm is rotatably installed inside the fixed block. A first motor is fixedly installed on the outside of the fixed block. The output end of the first motor penetrates through the fixed block and is fixedly connected to the inside of the rotating arm. A groove is provided at one end of the rotating arm away from the fixed block. And a forearm is rotatably installed at the groove of the rotating arm. A second motor is fixedly installed on the outside of the rotating arm. The output end of the second motor is fixedly connected to the inside of the forearm.

[0012] Preferably, the clamping mechanism includes a connecting plate. The connecting plate is fixedly installed at one end of the forearm away from the rotating arm. And a guide rail is fixedly installed on the side of the connecting plate away from the forearm. The guide rails are symmetrically installed along the central axis position of the connecting plate. And a slider is slidably installed between the guide rails. The sliders are symmetrically installed between the guide rails. Cylinders are fixedly installed at the corners on the side of the connecting plate away from the forearm.

[0013] Preferably, the output end of the cylinder is fixedly connected to both ends of the slider. Connecting blocks are fixedly installed on the outer sides of the connecting plates. A fixed cover is fixedly installed on the outer side of the connecting block. An inner sliding cylinder is slidably installed on the inner wall of the fixed cover. The inner sliding cylinder is in contact with the surface of the piston rod of the cylinder. Through the contact between the inner sliding cylinder and the piston rod of the cylinder, during the clamping operation, the lubrication state of the cylinder is judged by the friction between the piston rod and the inner sliding cylinder. Synchronous lubrication is carried out at the moment when lubrication is required, avoiding manual judgment and resulting in serious wear of the cylinder. Oil outlet holes are evenly formed in the inner wall of the inner sliding cylinder. An oil inlet hole is formed in the outer side of the fixed cover. A snap ring is arranged on the inner wall of the fixed cover. A rubber gasket ring is fixedly installed between the snap ring and the inner sliding cylinder. A conical ring is fixedly installed on the outer side of the inner sliding cylinder. Through the cooperation of the conical ring with the oil inlet hole and the oil outlet holes, by using the friction between the inner sliding cylinder and the piston rod of the cylinder, during the operation, when lubrication is required, the inner sliding cylinder is driven to compress the rubber gasket ring, causing the conical ring to move, compressing the grease between the inner sliding cylinder and the fixed cover, and at the same time blocking the oil inlet hole, ensuring that the grease is led out from the oil outlet holes and coated on the surface of the piston rod to ensure the lubrication effect of the cylinder. The conical ring is located on the side of the snap ring away from the rubber gasket ring. The oil inlet hole of the fixed cover is located on the side of the snap ring away from the rubber gasket ring.

[0014] Preferably, the jaw mechanism includes a support block. The support block is fixedly installed on the outer side of the slider. A zigzag plate is fixedly installed on the outer side of the support block. A rubber gasket strip is fixedly installed on the inner wall of the zigzag plate. Claw blocks are fixedly installed on the tops of the opposite surfaces of the zigzag plate. By the end of the claw block away from the zigzag plate bending inwards in an arc and cooperating with the rubber gasket strip, while the two ends of the material are subjected to clamping pressure, the material is squeezed inwards by the arc-shaped claw blocks, causing the material to contact the rubber gasket strip, compressing the rubber gasket strip to deform, so that both the inner and outer sides of the material are also subjected to pressure. At the same time, the deformed rubber gasket strip increases the contact area and the friction force, improving the fixing effect and ensuring the safety during feeding and transportation, and preventing the material from slipping. The claw blocks are evenly installed along the axis, and the end of the claw block away from the zigzag plate bends inwards in an arc.

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

[0016] First, for the numerical control machine tool loading manipulator with a lubrication mechanism, through the cooperation of the spiral groove of the rotating ring and the annular groove of the rotating slot, when the lubricating oil in the oil cover enters the annular groove through the conduit and surges to fill the contact between the rotating ring and the annular groove, by the driving of the spiral groove of the rotating ring on the lubricating oil when the rotating ring rotates, the lubricating oil is evenly coated on the contact surface. At the same time, during the rotation, the lubricating oil at the gap position moves. When rotating clockwise, it drives the lubricating oil to surge upwards, and when rotating counterclockwise, it drives the lubricating oil to impact downwards, enabling the lubricating oil in the annular groove to exchange heat quickly with the lubricating oil at the gap position, ensuring lubrication and improving the cooling effect at the same time.

[0017] Second, for the loading manipulator of the numerically controlled machine tool with a lubrication mechanism, when wear occurs during the relative rotation between the rotating ring and the rotating groove through the notch of the rotating groove, the worn debris particles slide downward during rotation. The notch provides a buffer space for the debris particles, reducing the friction with the contact surface, avoiding increased wear caused by debris accumulation, and at the same time affecting the accuracy of the mechanical claw.

[0018] Third, for the loading manipulator of the numerically controlled machine tool with a lubrication mechanism, through the contact between the inner sliding cylinder and the piston rod of the cylinder, during the clamping operation, the lubrication state of the cylinder is judged by the friction between the piston rod and the inner sliding cylinder, and synchronous lubrication is carried out at the moment when lubrication is required, avoiding serious wear of the cylinder caused by manual judgment.

[0019] Fourth, for the loading manipulator of the numerically controlled machine tool with a lubrication mechanism, through the cooperation of the conical surface ring with the oil inlet hole and the oil outlet hole, using the friction between the inner sliding cylinder and the piston rod of the cylinder, when lubrication is required during operation, the inner sliding cylinder is driven to compress the rubber gasket ring, causing the conical surface ring to move, compressing the grease between the inner sliding cylinder and the fixed cover, and at the same time blocking the oil inlet hole, ensuring that the grease is exported from the oil outlet hole and coated on the surface of the piston rod to ensure the lubrication effect of the cylinder.

[0020] Fifth, for the loading manipulator of the numerically controlled machine tool with a lubrication mechanism, one end of the claw block away from the zigzag plate is bent inward in an arc, cooperating with the rubber gasket strip. While the two ends of the material are subjected to clamping pressure, the material is inwardly extruded by the arc-shaped clamping block, causing the material to contact the rubber gasket strip, compressing the rubber gasket strip to deform, so that both the inner and outer sides of the material are also subjected to pressure. At the same time, the deformed rubber gasket strip increases the contact area and the friction force, improving the fixing effect, ensuring the safety during loading and transportation, and preventing the material from slipping.

[0033] The first embodiment is as Figures 1 to 6 shown. The present invention provides a technical solution:

The outer side of the rotating ring 10 is rotationally adapted to the inner wall of the rotating groove 9, and the bottom of the rotating ring 10 is in contact with the notch of the rotating groove 9. During the process of driving the top disc 7 to rotate by the third motor 6 to change the direction of the swing arm mechanism 3, while the top disc 7 rotates, it drives the rotating ring 10 to rotate. By using the rotational adaptation between the rotating ring 10 and the rotating groove 9, support and limitation are provided for the rotation of the swing arm mechanism 3. The outer side of the rotating ring 10 is evenly provided with spiral grooves. A third motor 6 is fixedly installed on the inner wall of the top cover 2. The output end of the third motor 6 is flange-connected to the central position at the bottom of the top disc 7. An oil cover 8 is fixedly installed on the top of the top cover 2. The oil cover 8 is located outside the rotating groove 9. When the rotating ring 10 and the rotating groove 9 rotate relative to each other, the ring groove of the rotating groove 9 is communicated with the oil cover 8 through the conduit 11, so that the liquid lubricating oil in the oil cover 8 is introduced into the ring groove of the rotating groove 9 through the conduit 11 and surges in the ring groove of the rotating groove 9 to fill the gap between the rotating groove 9 and the rotating ring 10. At the same time, in cooperation with the rotation of the rotating ring 10, by using the spiral grooves on the outer side of the rotating ring 10, when stationary, the lubricating oil fills into the spiral grooves. During the rotation process, by using the driving of the spiral grooves on the lubricating oil, the lubricating oil is evenly coated in the gap of the contact surface between the rotating ring 10 and the rotating groove 9, and a conduit 11 is fixedly installed between the oil cover 8 and the rotating groove 9. One end of the conduit 11 close to the rotating groove 9 is communicated with the ring groove of the rotating groove 9.

[0040] The swing arm mechanism 3 includes a fixed block 32. The fixed block 32 is fixedly installed at the central position on the top of the top disc 7, and a swing arm 33 is rotatably installed on the inner wall of the fixed block 32. A first motor 31 is fixedly installed on the outer side of the fixed block 32. The output end of the first motor 31 penetrates through the fixed block 32 and is fixedly connected to the inner wall of the swing arm 33. A groove is opened at one end of the swing arm 33 away from the fixed block 32. By fixedly connecting the top disc 7 with the fixed block 32, during the rotation process, the first motor 31 cooperates with the second motor 34. By using the first motor 31 to drive the swing arm 33 to rotate, the included angle between the swing arm 33 and the fixed block 32 is controlled. In cooperation with the second motor 34 driving the front arm 35 to rotate, the included angle between the swing arm 33 and the front arm 35 is controlled to drive the clamping mechanism 4 to move and control the clamping angle and clamping position. And a front arm 35 is rotatably installed at the groove of the swing arm 33. A second motor 34 is fixedly installed on the outer side of the swing arm 33. The output end of the second motor 34 is fixedly connected to the inner wall of the front arm 35.

[0041] Second Embodiment. On the basis of the first embodiment, please refer to Figures 7 to 8As shown, the clamping mechanism 4 includes a connecting plate 41. The connecting plate 41 is fixedly installed at one end of the forearm 35 away from the rotating arm 33. And on the side of the connecting plate 41 away from the forearm 35, a guide rail 43 is fixedly installed. The guide rails 43 are symmetrically installed along the central axis position of the connecting plate 41. And a slider 42 is slidably installed between the guide rails 43. The cylinder 44 drives the slider 42 to move under the restriction of the guide rails 43. During the process of clamping an object, the cylinder 44 drives the sliders 42 to approach each other, making the jaw mechanisms 5 approach each other to clamp the object. At the same time, during the process of the cylinder 44 driving the slider 42 to move, by the inner sliding cylinder 46 contacting the surface of the piston rod of the cylinder 44, the sliders 42 are symmetrically installed between the guide rails 43, and cylinders 44 are fixedly installed at the corners on the side of the connecting plate 41 away from the forearm 35.

[0042] The output end of the cylinder 44 is fixedly connected to both ends of the slider 42. Connecting blocks 47 are fixedly installed on the outer sides of the connecting plate 41. A fixed cover 45 is fixedly installed on the outer side of the connecting block 47. An inner sliding cylinder 46 is slidably installed on the inner wall of the fixed cover 45. The inner sliding cylinder 46 contacts the surface of the piston rod of the cylinder 44. Oil outlet holes are evenly formed in the inner wall of the inner sliding cylinder 46. An oil inlet hole is formed on the outer side of the fixed cover 45. And a snap ring is arranged on the inner wall of the fixed cover 45. During the operation of the cylinder 44, when the lubricating grease on the surface of the piston rod decreases, the friction between the piston rod and the inner sliding cylinder 46 increases. When the piston rod extends to drive the sliders 42 to approach each other, the inner sliding cylinder 46 is driven to move by the frictional force, compressing the rubber gasket ring 49 to deform. At the same time, during the movement of the inner sliding cylinder 46, the conical ring 48 is driven to move together. During the movement, the grease between the inner sliding cylinder 46 and the fixed cover 45 is extruded. At the same time, during the movement, the conical ring 48 blocks the oil inlet hole of the fixed cover 45, so that the grease is led out from the oil outlet holes of the inner sliding cylinder 46. During the movement of the piston rod of the cylinder 44, it is coated on the surface of the piston rod for lubrication. And a rubber gasket ring 49 is fixedly installed between the snap ring and the inner sliding cylinder 46. A conical ring 48 is fixedly installed on the outer side of the inner sliding cylinder 46. The conical ring 48 is located on the side of the snap ring away from the rubber gasket ring 49. The oil inlet hole of the fixed cover 45 is located on the side of the snap ring away from the rubber gasket ring 49.

[0043] Third Embodiment. On the basis of the First and Second Embodiments, please refer to Figures 9 to 10As shown in the figure, the jaw mechanism 5 includes a support block 51, which is fixedly installed on the outside of the slider 42, and a zigzag plate 53 is fixedly installed on the outside 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. During the approaching process, the zigzag plates 53 are driven to approach each other. The jaw blocks 54 on the opposite surfaces of the zigzag plates 53 contact the material. A rubber gasket strip 52 is fixedly installed on the inner wall of the zigzag plate 53. Jaw blocks 54 are fixedly installed at the tops of the opposite surfaces of the zigzag plate 53. By using the arc bending of the jaw blocks 54, during the clamping process, the material is driven to approach the rubber gasket strip 52, so that while the material is clamped and pressed at both ends, the rubber deformation of the arc of the jaw blocks 54 and the rubber gasket strip 52 enables the inner and outer sides of the material to be simultaneously subjected to clamping pressure, ensuring the fixing effect. The jaw blocks 54 are uniformly installed along the axis, and the end of the jaw block 54 away from the zigzag plate 53 is bent inward in an arc shape.

[0044] During use, it is supported by the base 1. The third motor 6 drives the top plate 7 to rotate, changing the clamping direction of the swing arm mechanism 3. At the same time, the swing arm mechanism 3 controls the clamping angle. By cooperation, the clamping mechanism 4 is brought close to the material to be loaded. The clamping mechanism 4 drives the jaw mechanisms 5 to approach each other, clamping the loaded material, and performing loading and transportation under the cooperation of the third motor 6 and the swing arm mechanism 3.

[0045] During the process of driving the top plate 7 to rotate by the third motor 6 to change the direction of the swing arm mechanism 3, while the top plate 7 rotates, it drives the rotating ring 10 to rotate. By using the rotational adaptation between the rotating ring 10 and the rotating groove 9, support and limitation are provided for the rotation of the swing arm mechanism 3. When the rotating ring 10 and the rotating groove 9 rotate relative to each other, the annular groove of the rotating groove 9 is communicated with the oil cover 8 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 through the conduit 11 and surges in the annular groove of the rotating groove 9, filling the gap between the rotating groove 9 and the rotating ring 10. At the same time, in cooperation with the rotation of the rotating ring 10, by using the spiral groove on the outside of the rotating ring 10, when it is stationary, the lubricating oil fills into the spiral groove. During the rotation process, by using the driving of the spiral groove on the lubricating oil, the lubricating oil is evenly coated in the gap of the contact surface between the rotating ring 10 and the rotating groove 9.

[0046] In the swing arm mechanism 3, the top plate 7 is fixedly connected to the fixed block 32. During the rotation process, the first motor 31 and the second motor 34 cooperate. The first motor 31 drives the swing arm 33 to rotate, controlling the angle between the swing arm 33 and the fixed block 32. In cooperation with the second motor 34 driving the front arm 35 to rotate, controlling the angle between the swing arm 33 and the front arm 35, driving the clamping mechanism 4 to move, and controlling the clamping angle and the clamping position.

[0047] In the clamping mechanism 4, the cylinder 44 drives the slider 42 to move under the restriction of the guide rail 43. During the process of clamping an object, the cylinder 44 drives the sliders 42 to approach each other, causing the jaw mechanisms 5 to approach each other to clamp the object. At the same time, during the process of the cylinder 44 driving the slider 42 to move, the inner sliding cylinder 46 contacts the surface of the piston rod of the cylinder 44. During the operation of the cylinder 44, when the lubricating grease on the surface of the piston rod decreases, the friction between the piston rod and the inner sliding cylinder 46 increases. When the piston rod extends to drive the sliders 42 to approach each other, the inner sliding cylinder 46 is driven to move by the frictional force, compressing the rubber gasket 49 to deform. At the same time, during the movement of the inner sliding cylinder 46, the conical ring 48 is driven to move together. During the movement, the grease between the inner sliding cylinder 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, causing the grease to be discharged from the oil outlet hole of the inner sliding cylinder 46, and lubricating the surface of the piston rod during the movement of the piston rod of the cylinder 44.

[0048] In the jaw 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. During the approaching process, the zigzag plates 53 are driven to approach each other. The claw blocks 54 on the opposite surfaces of the zigzag plates 53 contact the material, and by using the arc bending of the claw blocks 54, during the clamping process, the material is driven to approach the rubber gasket strip 52, so that while the material is clamped and pressed at both ends, the rubber deformation of the arc of the claw blocks 54 and the rubber gasket strip 52 causes the inner and outer sides of the material to be simultaneously subjected to clamping pressure, ensuring the fixing effect.
