Description

Technical Field

[0001] The invention relates to the technical field of bearing retainer assembly, and in particular to a manipulator for a bearing retainer assembly machine. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Its main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. The bearing cage refers to the bearing part that partially wraps all or part of the rolling elements and moves with them. It is used to isolate the rolling elements and usually guide the rolling elements and keep them in the bearing. The cage must withstand the stress caused by friction, strain and inertial force, as well as the chemical corrosion of lubricants, additives in lubricants or substances generated by their aging, organic solvents or coolants. The installation of the cage is the next process of the bearing after the ball is installed.

[0003] In the prior art, when assembling the bearing retainer by an assembly machine, the bearing is mostly clamped by a robot and placed on the lower die, and then the retainer is press-fitted and assembled by moving the upper die downward. When the robot clamps the bearing, it mostly clamps the outer ring of the bearing, which is not convenient for clamping and positioning the inner ring and outer ring of the bearing at the same time, resulting in limited clamping effect and insufficient stability of the bearing. The bearing is easily displaced when placed on the lower die, affecting subsequent assembly work. Summary of the invention

[0029] The motor 1 is fixed to the mounting seat 9 with bolts, and the base 10 is fixed to the assembly table with bolts. The motor 1 is fixed by connecting the mounting seat 9 with the base 10. The motor 1 drives the rotating shaft 2 to rotate, which can rotate the rotating arm 4 and the clamping assembly 8 to the top of the bearing part. The lifting arm 3 is convenient for adjusting the height of the clamping assembly 8. The telescopic arm 5 moves in the rotating arm 4 to adjust the horizontal position of the clamping assembly 8. The clamping plate 7 is driven downward by the electric push rod 6 to move the clamping plate 7 to the top of the bearing part, and then the bearing is clamped by the clamping assembly 8 and moved to the upper die.

[0030] In the specific implementation process, Figure 3 and Figure 4 As shown, the clamping assembly 8 includes a dual-axis motor 81 arranged inside the clamping disk 7, both ends of the dual-axis motor 81 are fixedly connected with a screw rod 82, a threaded block 83 is screwed on the screw rod 82, a first arc plate 84 is fixedly connected to one side of the top of the threaded block 83, second arc plates 85 are slidably arranged on both sides of the top of the clamping disk 7, a moving block 86 is fixedly connected to the bottom of the second arc plate 85, a support rod 87 is inserted into the inner wall of the moving block 86, and a spring 88 is sleeved on the outer side of the support rod 87.

[0031] The two second arc plates 85 are pushed to move, and the second arc plates 85 drive the moving block 86 to slide on the support rod 87 and squeeze the spring 88. After the clamping plate 7 contacts the top of the bearing component, the second arc plates 85 are released to allow it to expand outward under the elastic force of the spring 88, thereby clamping the inner ring of the bearing component. The two lead screws 82 are driven to rotate by the dual-axis motor 81, so that the threaded block 83 drives the two first arc plates 84 to move toward each other, thereby clamping the outer ring of the bearing component, thereby improving the stability of the clamping of the bearing component.

[0032] The first sliders 11 are fixedly connected to both sides of the threaded block 83. The outer side of the first slider 11 is slidably connected to the inner wall of the clamping plate 7. The first slider 11 guides and limits the threaded block 83 to improve the stability of the threaded block 83 when moving.

[0033] The second sliders 12 are fixedly connected to both sides of the moving block 86. The outer sides of the second sliders 12 are slidably connected to the inner wall of the clamping plate 7. The second sliders 12 guide and limit the moving block 86 to improve the stability of the moving block 86 when moving.

[0035] Connecting blocks 15 are fixedly connected to both sides of the top of the mounting seat 9 , and a sliding groove 16 for use with the connecting blocks 15 is provided on the top of the base 10 .

[0036] A mounting block 17 is fixedly connected to the top of the connecting block 15 , and a mounting groove 18 for use with the mounting block 17 is connected to one side of the sliding groove 16 .

[0037] Four corresponding first fixing blocks 19 and second fixing blocks 20 are fixedly connected to the outer sides of the mounting seat 9 and the base 10 , respectively. Fixing bolts 21 are disposed inside the first fixing blocks 19 and the second fixing blocks 20 .

[0038] The bottom of the mounting seat 9 is fixedly connected with a positioning plate 13, which is engaged with the positioning groove 14 through the positioning plate 13, and then inserted into the mounting groove 18 and the slide groove 16 inside the base 10 through the connecting block 15 and the mounting block 17 at the bottom of the mounting seat 9, and the base 9 is installed on the top of the mounting seat 10, and then the mounting seat 9 is rotated to drive the mounting block 17 to enter the slide groove 16, so that the first fixing block 19 is aligned with the second fixing block 20, and the mounting block 17 is limited, so that the mounting seat 9 is quickly installed on the top of the base 10, which is convenient for the installation and disassembly of the manipulator. After the first fixing block 19 is aligned with the second fixing block 20, the first fixing block 19 and the second fixing block 20 are fixed by the fixing bolts 21, so as to improve the stability of the mounting seat 9 and prevent it from shaking during work.

[0039] When in use, the two second arc plates 85 are pushed to move, and the second arc plates 85 drive the moving block 86 to slide on the support rod 87 and squeeze the spring 88. After the clamping plate 7 contacts the top of the bearing component, the second arc plates 85 are released to allow it to expand outward under the elastic force of the spring 88, thereby clamping the inner ring of the bearing component. The two screw rods 82 are driven to rotate by the dual-axis motor 81, so that the threaded block 83 drives the two first arc plates 84 to move toward each other, thereby clamping the outer ring of the bearing component, thereby improving the stability of the clamping of the bearing component.
