[0051] In order to more clearly understand the above-mentioned objects, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other in the absence of conflict.
[0052] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.
[0053] Refer to the following Figures 1 to 14 A manipulator with a bearing quality detection function provided according to some embodiments of the present application is described.
[0054] like Figure 1 As shown, according to some embodiments of the present application, a manipulator with a bearing quality detection function includes a manipulator assembly 1, a manipulator assembly 2, a friction reduction assembly 3, an inductive sensing assembly 4, a transmission assembly 5, and a detection assembly 6. The manipulator assembly 1 is composed of multiple manipulators and is used to adjust the gripping position; the manipulator assembly 2 is connected to the manipulator assembly 1 and is used to clamp the bearing 7; the friction reduction assembly 3 is arranged on the manipulator assembly 2; the inductive sensing assembly 4 is connected to the manipulator assembly 2; multiple transmission assemblies 5 are arranged on both sides of the manipulator assembly 2; and the detection assembly 6 is arranged on the manipulator assembly 2 and is arranged farther away from the manipulator assembly 1 than the manipulator assembly 2.
[0055] It should be noted that the robot arm assembly 1 serves as a base support structure to provide support for the robot. The bearing 7 is grasped by the robot arm assembly 2, and the bearing 7 is detected through this device, that is, the detection assembly 6 performs the detection work, and by rotating the transmission bearing 7, it is detected whether the bearing 7 makes abnormal noise during rotation, so as to achieve the purpose of detection.
[0056] When the manipulator with the bearing quality detection function is working, first the connecting arms of the manipulator assembly 1 rotate to adjust the position of the manipulator assembly 2, and the internal structure of the manipulator assembly 2 is driven to move the manipulator, then the inductive sensor assembly 4 performs inductive transmission, and the transmission assembly 5 receives the induction and opens the device, then the manipulator extends to grab the bearing 7 and enters the device for detection, then the manipulator is recovered, and the transmission assembly 5 receives the signal of the inductive sensor assembly 4 to close the device, so that the detection assembly 6 performs the bearing 7 detection work.
[0057] In some possible embodiments, such as Figure 1 As shown, the robot arm assembly 1 includes: a base 11; a first connecting arm 12, which is arranged on the base 11; a second connecting arm 13, which is rotatably connected to the first connecting arm 12; a third connecting arm 14, which is rotatably connected to the second connecting arm 13; and a mounting tube 15, which is connected to the third connecting arm 14 and is used to fix the robot arm assembly 2.
[0058] In this embodiment, the base 11 provides overall support and fixation for the device, and the first connecting arm 12, the second connecting arm 13 and the third connecting arm 14 rotate within a certain range, so that they can reach and operate the bearing 7 away from the base, thereby expanding its working range. The mounting cylinder 15 serves as an intermediate connecting component to connect and fix the manipulator assembly 2 to ensure stable operation of the manipulator assembly 2.
[0059] In some possible embodiments, such as Figure 2-4 As shown, the manipulator assembly 2 includes: a sound insulation tube 21, fixedly connected to the bottom end of the mounting tube 15; a first electric push rod 22, arranged inside the mounting tube 15; a connecting frame 23, fixedly connected to the first electric push rod 22; a mounting plate 24, arranged on the connecting frame 23, and the mounting plate 24 has a plurality of grooves distributed in an array; a pneumatic actuator 25, arranged on the mounting plate 24; and a plurality of moving claws 26, connected to the pneumatic actuator 25, and passing through the mounting plate 24.
[0060] In this embodiment, the sound insulation tube 21 is cylindrical, and its purpose is to reduce the interference of external noise on the internal detection work. The first electric push rod 22 is responsible for providing linear motion power. By pushing the mounting plate 24, the mounting plate 24 drives the pneumatic actuator 25 and the moving claw 26 to move. The mounting plate 24 supports the pneumatic actuator 25, and the pneumatic actuator 25 is responsible for providing power to the moving claw 26. The bearing 7 is grasped and released by the contraction and expansion of the moving claw 26. At the same time, the mounting plate 24 is provided with the same number of grooves as the moving claw 26 to accommodate the movement of the moving claw 26 inside, thereby improving the movement stability of the moving claw 26.
[0061] In some possible embodiments, such as Figure 4 As shown, a plurality of moving claws 26 are distributed in an array, and each moving claw 26 includes a rubber sleeve 27 fixedly connected to the moving claw 26 , and a plurality of protrusions are provided on the surface of the rubber sleeve 27 .
[0062] In this embodiment, the rubber sleeve 27 is arranged at the output end of the pneumatic actuator 25, and contacts the bearing 7 through the rubber sleeve 27. It is made of soft and wear-resistant material to increase the friction between the rubber sleeve 27 and the bearing 7, thereby preventing the bearing 7 from slipping during the grasping process and improving the grasping stability.
[0063] In some possible embodiments, such as Figure 12-14 As shown, the friction deceleration assembly 3 includes: a movable seat 31, which is arranged on the sound insulation tube 21; a first spring 32, which is arranged on the movable seat 31; an extrusion piece 33, which is connected to the movable seat 31; a second spring 34, which is arranged on the extrusion piece 33; and a friction belt 35, which is fixedly connected to the extrusion piece 33 and contacts the outer surface of the bearing 7.
[0064] In this embodiment, the movable seat 31 is in an active state and is movably installed on the sound insulation tube 21. During the movement of the bearing 7, friction is generated by contact with the friction belt 35, and the friction force with its surface is used to achieve a deceleration and braking effect. The second spring 34 provides a certain elastic support for the extrusion piece 33, so that it can better adapt to the shape changes of the outer surface of the bearing 7 and can absorb the impact energy generated by the bearing 7 to a certain extent. When the movable seat 31 is in an extruded state, the first spring 32 is compressed. After the bearing 7 moves downward, the movable seat 31 is unrestricted, and the first spring 32 restores its elasticity, so that the extrusion piece 33 and the friction belt 35 and other components move outward, preventing the extrusion piece 33 from interfering with the mechanical grasping work of the manipulator assembly 2.
[0065] In some possible embodiments, such as Figure 7 As shown, the inductive sensing assembly 4 includes: a grating sensor 41 connected to the inner wall of the sound insulation tube 21 , and the grating sensor 41 is provided with two sensing points; a positioning module 42 fixedly connected to the mounting plate 24 .
[0066] In this embodiment, the grating sensor 41 is arranged on the inner wall of the sound insulation tube 21, and two sensing points are arranged inside it. When the positioning module 42 moves to the corresponding two positions, the positioning module 42 sends a signal to the grating sensor 41, thereby driving the transmission component 5 to work, improving the degree of automation of the device and thus improving work efficiency.
[0067] In some possible embodiments, such as Figure 5 、 Figure 6 As shown, multiple transmission components 5 are symmetrically distributed on both sides of the sound insulation tube 21. Each transmission component 5 includes: a second electric push rod 51, which is fixedly connected to the sound insulation tube 21; a toggle block 52, which is provided on the second electric push rod 51; an opening and closing door 53, which is transmission-connected to the toggle block 52 and has a semicircular shape; and a support base 54, which is rotationally connected to the toggle block 52 and fixed to the sound insulation tube 21.
[0068] In this embodiment, the second electric push rod 51 serves as the power source of the transmission assembly 5. The second electric push rod 51 receives the signal from the grating sensor 41 to start driving. The toggle block 52 is installed at the end of the second electric push rod 51, and the end of the second electric push rod 51 moves downward, so that the bottom of the toggle block 52 rotates with the support seat 54 as the center, and the opening and closing door 53 rotates accordingly to perform the opening and starting action. This transmission method can quickly respond to the instructions of the second electric push rod 51. At the same time, the top structure of the opening and closing door 53 contacts the above-mentioned moving seat 31, so that the friction reduction assembly 3 is in the working position.
[0069] In some possible embodiments, such as Figure 8-11As shown, the detection assembly 6 includes: a guide seat 61, which is fixedly connected to the sound insulation tube 21; a third spring 62, which is arranged on the guide seat 61; a lifting block 63, which is fixedly connected to the bottom end of the guide seat 61; a toggle member 64, which is rotatably connected to the lifting block 63, and the toggle member 64 and the lifting block 63 can only rotate upward; an extension rod 65, which is fixedly connected to the lifting block 63, and the extension rod 65 extends away from the lifting block 63 and contacts the top surface of the connecting frame 23.
[0070] In this embodiment, the manipulator assembly 2 at the bottom of the connecting frame 23 grabs the bearing 7 and moves upward, and retracts into the sound insulation tube 21 for detection. Since the extension rod 65 contacts the top of the connecting frame 23, the extension rod 65 moves upward accordingly, and at the same time, the lifting block 63 moves upward along the guide seat 61, the third spring 62 is compressed, and the toggle member 64 moves upward accordingly; when the connecting frame 23 moves downward, the limit on the extension rod 65 is cancelled, and the elasticity is restored from the third spring 62, so that the lifting block 63 moves downward, and the toggle member 64 moves downward accordingly. During the downward movement of the toggle member 64, it will be rotated upward by external force and is only allowed to rotate upward, ensuring that the toggle member 64 can move to a predetermined position when subjected to external force.
[0071] In some possible embodiments, such as Figure 8-11 As shown, the detection assembly 6 also includes: a fixed seat 66, which is fixedly connected to the sound insulation tube 21; a slot column 67, which is rotatably connected to the fixed seat 66, and the toggle member 64 moves in the slot column 67; a torsion spring 68, which is arranged on the slot column 67; a spiral piece 69, which is fixedly connected to the slot column 67, is spiral-shaped, and contacts the outer surface of the bearing 7.
[0072] In this embodiment, after the toggle member 64 is driven to move upward, it moves along the groove in the slot column 67. Since the groove is spiral, the slot column 67 is driven to rotate one hundred and eighty degrees by the upward force of the toggle member 64, so that the bottom torsion spring 68 and the spiral piece 69 rotate accordingly until the toggle member 64 is separated from the slot column, so that the torsion spring 68 rebounds, and the spiral piece 69 is driven to reverse. Since the spiral piece 69 is spiral, the spiral piece 69 drives the bearing 7 to rotate to perform the detection work.
[0073] In some possible embodiments, such as Figure 5 As shown, the detection assembly 6 also includes: a plurality of stethoscopes 70 evenly arranged on the sound insulation tube 21.
[0074] In this embodiment, the stethoscope 70 is disposed on the inner surface of the sound insulation tube 21 near the bearing 7 to ensure that the stethoscope 70 can capture the sound emitted by the bearing 7 for detection.
[0075] When the manipulator with bearing quality detection function is working, the manipulator assembly 2 is adjusted to the top of the detection bearing 7 through the rotation adjustment of the first connecting arm 12, the second connecting arm 13 and the third connecting arm 14, so that the first electric push rod 22 of the manipulator assembly 2 is started, pushing the connecting frame 23 and the mounting plate 24 to move downward, and the positioning module 42 moves downward accordingly, sending a signal to the grating sensor 41, so that the transmission assembly 5 is driven, that is, the end of the second electric push rod 51 moves downward, so that the bottom of the toggle block 52 rotates with the support seat 54 as the center of the circle, and the opening and closing door 53 rotates accordingly to perform the opening and starting action, so that the pneumatic actuator 25 drives the multiple moving claws 26 to expand, through the rubber sleeve 27 contacts the inner surface of the bearing 7 and grabs the bearing 7, so that the first electric push rod 22 shrinks and enters the sound insulation tube 21 for detection. The positioning module 42 moves up with the mounting plate 24, and the grating sensor 41 drives the transmission assembly 5 again to close the opening and closing door 53. At the same time, the extension rod 65 moves up with the connecting frame 23, and the third spring 62 is compressed. The toggle member 64 moves up accordingly and moves along the groove in the slot column 67. Since the groove is spiral, the slot column 67 is driven to rotate 180 degrees by the upward force of the toggle member 64, so that the bottom torsion spring 68 and the spiral piece 69 rotate accordingly until the toggle member 64 is separated from the slot column, so that the torsion spring 68 rebounds and the spiral piece 69 is driven Reverse, and the spiral piece 69 is spiral, then the spiral piece 69 drives the bearing 7 to rotate, and the stethoscope 70 inside the sound insulation tube 21 captures the sound emitted by the bearing 7 to detect the bearing 7. After the detection is completed, the first electric push rod 22 is started to send the bearing 7 out, the connecting frame 23 moves down, and the limit on the extension rod 65 is cancelled. The elasticity is restored from the third spring 62, so that the lifting block 63 moves down, and the toggle member 64 moves down accordingly. During the downward movement of the toggle member 64, it will be rotated outward to prevent it from continuing to move along the inner groove of the slot column 67. During the downward movement of the bearing 7, it will contact the friction belt 35, and friction will be generated by contact with the friction belt 35. The friction force with its surface is used to achieve a buffering effect. The second spring 34 A certain amount of elastic support is provided for the extrusion piece 33, so that it can better adapt to the shape changes of the outer surface of the bearing 7 and can absorb the impact energy generated by the bearing 7 to a certain extent. At the same time, the opening and closing door 53 in the transmission assembly 5 is opened, and the restriction on the movable seat 31 is cancelled, then the first spring 32 restores its elasticity, so that the extrusion piece 33 and the friction belt 35 and other components move outward, preventing the extrusion piece 33 from interfering with the mechanical grasping work of the manipulator assembly 2. At the same time, when the opening and closing door 53 is closed, it contacts the movable seat 31, causing the first spring 32 to be compressed, and then the extrusion piece 33 and the friction belt 35 return to their initial positions, ready for the next detection task. The whole process is highly automated, which reduces manual intervention and improves work efficiency.
