DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this technical field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-9The visual calibration and measurement device for bearing processing of this embodiment includes a base 1 and a visual inspection instrument 11. A conveying unit 8 and a track column 2 for conveying bearings are installed on the upper surface of the base 1. A Y-axis adjustment unit 3 is installed on the track column 2. A mounting plate 10 is installed on one side of the track column 2. The visual inspection instrument 11 is installed on the bottom surface of the mounting plate 10. A first motor 4 is installed on one side of the Y-axis adjustment unit 3. A center adjustment unit 5 is fixedly installed on the output end of the first motor 4. A bearing fixing frame 6 is installed on one side of the center adjustment unit 5. The Y-axis adjustment unit 3 controls the movement of the bearing fixing frame 6 through the center adjustment unit 5. The center adjustment unit 5 adjusts the bearing rotation and the relative position of the visual inspection instrument 11, and the bearing fixing frame 6 includes a fixing rod 61 installed with the center adjustment unit 5, and a second motor 66 is installed on the side wall of one end of the fixing rod 61, and the output end of the second motor 66 is fixedly connected to the first cylinder 62, and the other side wall of one end of the fixing rod 61 is rotatably connected to the first fixing block 63, and the output shaft of the first cylinder 62 passes through the first fixing block 63 and is fixedly connected to the second fixing block 64, and the first fixing block 63 is slidably connected to the output shaft of the first cylinder 62, and a rubber extrusion sleeve 65 is fixedly connected between the outer walls of the first fixing block 63 and the second fixing block 64.

[0032] Specifically, the structure of the visual calibration measuring device in the present invention is similar to that of the existing visual calibration measuring device. The main improvement of the present invention is that both sides of the bearing are quickly and automatically inspected and measured to improve efficiency. When the bearing needs to be inspected, the present invention puts the bearing sleeve outside the second fixing block 64, the rubber extrusion sleeve 65 and the first fixing block 63, and the fixing rod 61 supports the bearing. The first cylinder 62 is started to move the second fixing block 64 downward, and the rubber extrusion sleeve 65 is compressed in cooperation with the first fixing block 63, so that the rubber extrusion sleeve 65 is bent and squeezed against the inner wall of the bearing to fix the bearing. At this time, the visual inspection instrument 11 on the mounting plate 10 measures and inspects one side of the bearing. After the surface inspection is completed, the first motor 4 is started, and the first motor 4 drives the fixed rod 61 to rotate through the central adjustment unit 5, and the fixed rod 61 drives the bearing to turn over, and the visual inspection instrument 11 inspects the other side of the bearing, and the second motor 66 is started, and the second motor 66 drives the first cylinder 62 to rotate, and the first cylinder 62 drives the first fixed block 63, the second fixed block 64 and the rubber extrusion sleeve 65 to rotate, so that the bearing rotates, and the part of the bearing blocked by the fixed rod 61 is turned outside the fixed rod 61, so that the visual inspection instrument 11 performs a complete inspection on the other side of the bearing, and a single visual inspection instrument 11 is used to achieve double-sided measurement and inspection of the bearing, which reduces equipment costs, improves inspection efficiency, and facilitates production.

[0033] Specifically, the conveying unit 8 includes a belt conveyor 81, which is installed on the upper surface of the base 1; after the double-sided inspection of the bearing is completed, the bearing is rotated to be located below the fixing rod 61. At this time, the second fixing block 64 is moved away from the first fixing block 63 by the first cylinder 62, so that the rubber extrusion sleeve 65 is straightened, thereby canceling the fixation of the bearing, and the bearing falls directly onto the belt conveyor 81, realizing automatic unloading of the bearing. The belt conveyor 81 transports the bearing to improve practicality.

[0034] Specifically, the Y-axis adjustment unit 3 includes a slider 34 slidably connected to the track column 2, a threaded rod 32 and a stabilizing rod 33 are passed through the slider 34, the threaded rod 32 is threadedly connected to the slider 34, a third motor 31 is installed at the upper end of the track column 2, the output end of the third motor 31 passes through the track column 2 and is threadedly connected to the threaded rod 32, the threaded rod 32 is rotatably connected to the track column 2, the stabilizing rod 33 is fixedly connected to the track column 2, the first motor 4 is installed on one side of the slider 34, and the output shaft of the first motor 4 passes through the slider 34 and is connected to the center adjustment unit 5; the threaded rod 32 is driven by the third motor 31, and the slider 34 can be driven to move on the track column 2. The slider 34 slides inside and slides on the outer wall of the stabilizing rod 33. The slider 34 drives the first motor 4 and the fixed rod 61 to rise or fall, thereby driving the bearing to rise and fall to adapt to the focus of the visual inspection instrument 11. The visual inspection instrument 11 can accurately inspect the bearings, and at the same time, the uninspected bearings can be placed on the belt conveyor 81. The second fixed block 64 is rotated to the bottom of the fixed rod 61, and the Y-axis adjustment unit 3 is used to lower the second fixed block 64 and insert it into the bearing. Then, the first cylinder 62 cooperates with the rubber extrusion sleeve 65 to clamp the inner hole of the bearing, thereby realizing automatic removal of the bearing, improving the degree of automation, and ensuring production efficiency.

[0035] Specifically, the center adjustment unit 5 includes an adjustment disk 51, which is fixedly connected to the output shaft of the first motor 4. A slide groove 52 is provided on the side wall of the adjustment disk 51. One end of the fixed rod 61 is slidably connected to the slide groove 52. A threaded rotating rod 53 is rotatably connected in the slide groove 52. One end of the threaded rotating rod 53 passes through the fixed rod 61 and is threadedly connected thereto, and one end of the threaded rotating rod 53 passes through the outside of the adjustment disk 51. The rotation of the threaded rotating rod 53 can drive the fixed rod 61 to slide in the slide groove 52, thereby adjusting the eccentric angle of the fixed rod 61 on the adjustment disk 51, and then the first motor 4 drives the fixed rod 61 to rotate, so that when the bearing is vertical, the side wall of the bearing corresponds to the focus of the visual inspection instrument 11. Because the outer wall of the bearing may collide with the outer wall during transportation, resulting in wear and scratches, etc., the second motor 66 is used to drive the bearing to rotate, so that the visual inspection instrument 11 can detect the outer wall of the bearing to ensure the quality of the bearing. According to bearings of different thicknesses, the center adjustment unit 5 can adjust the bearing to different positions when it is vertical to improve adaptability.

[0036] Specifically, the conveying unit 8 also includes a discharge port 82 opened on the side wall of the belt conveyor 81, and a receiving plate 83 corresponding to the discharge port 82 is installed on the side wall of the belt conveyor 81. A classification unit 9 corresponding to the discharge port 82 is installed on the belt conveyor 81. The classification unit 9 includes a bracket 91, and the bracket 91 is installed on the outer wall of the belt conveyor 81. A gear shaft 92 is rotatably connected to the bracket 91. The lower end of the gear shaft 92 is fixedly connected to a guide plate 93 located above the belt conveyor 81, and the guide plate 93 corresponds to the discharge port 82. A third cylinder 94 is installed on the upper surface of the bracket 91, and the output shaft of the third cylinder 94 is fixedly connected to a rack 95 meshing with the gear shaft 92; when When the visual inspection instrument 11 detects that there is a problem with the quality of the bearing that has been normally inspected, the third cylinder 94 is started to work, and the third cylinder 94 drives the rack 95 to move, and the rack 95 drives the gear shaft 92 to rotate, and the bracket 91 drives the gear shaft 92 for support, and the gear shaft 92 drives the guide plate 93 to rotate, and the guide plate 93 is inclined. After the inspection, the bearings that do not meet the standards and fall on the belt conveyor 81 move along the guide plate 93 to the discharge port 82, and finally fall on the receiving tray 83, so as to realize automatic classification of the bearings that do not meet the standards and improve practicality. After the bearings are moved to the receiving tray 83, the output shaft of the third cylinder 94 moves back, so that the guide plate 93 turns back to transfer the conveying position of the belt conveyor 81 to the bearing.

[0037] Specifically, a limit unit 7 for limiting the outer ring of the bearing is installed on the fixed rod 61. The limit unit 7 includes a second cylinder 71 installed on the upper surface of the fixed rod 61. The output end of the second cylinder 71 is fixedly connected to a mounting frame 72. Two connecting rods 73 are installed in the mounting frame 72. The outer ends of the connecting rods 73 are fixedly connected to rollers 74. The second cylinder 71 is started to drive the mounting frame 72 to move. The mounting frame 72 drives the rollers 74 to move through the two rollers 74, so that the rollers 74 abut against the outer wall of the outer ring of the bearing. Therefore, when the second motor 66 drives the inner ring of the bearing to rotate through the rubber extrusion sleeve 65, the outer ring of the bearing does not rotate. The dynamics of the bearing can be detected by the visual inspection instrument 11 to ensure the quality of the bearing.

[0038] Specifically, the limiting unit 7 also includes two screw rods 75 rotatably connected to the inner wall of the mounting frame 72, and two connecting rods 73 are fixedly connected to the outer walls of the two screw rods 75 respectively. One end of the screw rod 75 passes through the outside of the mounting frame 72 and is threadedly connected with a nut 78; the connecting rod 73 can rotate along the screw rod 75 as the axis, thereby driving the roller 74 to rotate to adapt to bearings with different outer ring sizes. At the same time, after the angle of the connecting rod 73 is adjusted, the nut 78 is rotated to make it abut against the side wall of the mounting frame 72, so as to fix the screw rod 75, thereby fixing the connecting rod 73 and improving adaptability.

[0039] Specifically, the limiting unit 7 also includes a clearance opening 76 opened on the side wall of the connecting rod 73, and a gear plate 77 is fixedly connected in the clearance opening 76, and the gear plates 77 on the two connecting rods 73 are meshed and connected; when a single connecting rod 73 is rotated, the meshing of the two gear plates 77 drives the other connecting rod 73 to rotate synchronously in the opposite direction, so that the two connecting rods 73 are symmetrical with the second cylinder 71 as the axis, so that the rollers 74 at the outer ends of the two connecting rods 73 can both be against the outer wall of the outer ring of the bearing.

[0040] The implementation steps in this embodiment are as follows: when the bearing needs to be tested, the bearing is placed on the belt conveyor 81, and the belt conveyor 81 conveys the bearing. The threaded rod 32 is driven by the third motor 31 to drive the slider 34 to slide in the track column 2. The slider 34 slides on the outer wall of the stabilizing rod 33. The slider 34 drives the first motor 4 and the fixed rod 61 to descend. The first motor 4 is then used to rotate the second fixed block 64 to the position below the fixed rod 61, so that the second fixed block 64 descends into the bearing on the belt conveyor 81. At this time, the first cylinder 62 is started to move the second fixed block 64. The first fixing block 63 is moved to cooperate with the first fixing block 63 to compress the rubber extrusion sleeve 65, so that the rubber extrusion sleeve 65 is bent and squeezed with the inner wall of the bearing to fix the bearing, and then the Y-axis adjustment unit 3 is used to automatically take the bearing, and the first motor 4 is used to turn the bearing over. At this time, the visual inspection instrument 11 on the mounting plate 10 measures and inspects one side of the bearing. After the inspection of the bearing surface is completed, the first motor 4 is started to work, and the first motor 4 drives the fixing rod 61 to rotate through the center adjustment unit 5, and the fixing rod 61 drives the bearing to turn over. The visual inspection instrument 11 measures and inspects the outer wall of the outer ring of the bearing and the other side. The second motor 66 is started to work, the second motor 66 drives the first cylinder 62 to rotate, the first cylinder 62 drives the first fixing block 63, the second fixing block 64 and the rubber extrusion sleeve 65 to rotate, so that the bearing rotates, and the outer wall of the outer ring and the other side of the bearing are first detected. After the two sides of the bearing are detected, the bearing is rotated to be located below the fixing rod 61. At this time, the second fixing block 64 is moved away from the first fixing block 63 by the first cylinder 62, so that the rubber extrusion sleeve 65 is straightened, thereby canceling the fixation of the bearing, and the bearing directly falls on the belt conveyor 81, realizing The bearings are automatically unloaded and conveyed by the belt conveyor 81. If the visual inspection instrument 11 detects that the quality of the bearings inspected normally is problematic, the third cylinder 94 is started to work, and the third cylinder 94 drives the rack 95 to move, and the rack 95 drives the gear shaft 92 to rotate. The bracket 91 drives the gear shaft 92 for support, and the gear shaft 92 drives the guide plate 93 to rotate. The guide plate 93 is inclined. After the inspection, the bearings that do not meet the standards and fall on the belt conveyor 81 move along the guide plate 93 to the discharge port 82, and finally fall on the receiving tray 83, thereby realizing automatic classification of the bearings that do not meet the standards.

[0041] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
