Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, specifically to a bearing processing device with adjustable workstation. Background Technology

[0002] After bearing rings are manufactured, some may have burrs, leading to product defects. Therefore, they need to be ground and polished. Patent CN219380297U, entitled "A Bearing Ring Polishing Device," includes an operating table, a grinding roller, and airbags. The operating table has an annular inner cavity at its center. The grinding roller is rotatably connected to the annular inner cavity, and a grinding disc is movably connected to the outer side of the grinding roller. A support platform is also provided at the bottom of the annular inner cavity. Several airbags are fixedly connected to the inner wall of the annular inner cavity, and the airbags are connected to an external air pump through air supply pipes located within the operating table. The annular inner cavity is used to place the bearing ring, and the inflation of the airbags supports and fixes the bearing ring, thus achieving the positioning and fixation of the processed part. Finally, the inner ring is ground and polished by the grinding roller and grinding disc located inside the bearing ring. The operation is simple, the effect is good, and the grinding disc is retractable, facilitating the installation and placement of the bearing ring. However, in actual use, this bearing ring polishing device can only polish the inner side of the bearing ring, and cannot polish both the inner and outer sides of the bearing ring at the same time. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a bearing processing device with adjustable workstation.

[0004] The technical solution adopted by this utility model to solve its technical problem is an adjustable bearing processing device, including a base plate. A first hydraulic cylinder is fixed to the top of the base plate. A base support is fixed to the top of the piston rod of the first hydraulic cylinder. A first motor is fixed inside the base support. A support plate is fixed to the top of the base support. A rotary table is fixed to the output shaft of the first motor. An anti-slip pad is fixed to the top of the rotary table. A support and a second hydraulic cylinder are fixed to the support plate. A third hydraulic cylinder is fixed inside the support. A bracket is fixed to the bottom of the piston rod of the third hydraulic cylinder. Two sliding blocks are provided inside the bracket. Each component is rotatably connected to a pressure roller. A second motor is fixed to one side of the support. The output shaft of the second motor is connected to a first bidirectional lead screw via a coupling. Both slides have screw holes that are compatible with the first bidirectional lead screw. A base is fixed to the piston rod of the second hydraulic cylinder. A fourth hydraulic cylinder is fixed inside the base. A frame is fixed to the bottom end of the piston rod of the fourth hydraulic cylinder. A third motor is fixed to one side of the frame. Two sliders are provided inside the frame. The bottom ends of the two sliders are connected to polishing rods by bolts. The output shaft of the third motor is connected to a second bidirectional lead screw via a coupling. Both sliders have screw holes that are compatible with the second bidirectional lead screw.

[0005] By adopting the above technical solution, the piston rod of the first hydraulic cylinder drives the base to move vertically, which can adjust the height of the support plate as needed and place the bearing ring on the anti-slip pad. The piston rod of the third hydraulic cylinder drives the bracket to move downward, which can adjust the height of the two pressure rollers. The output shaft of the second motor drives the first bidirectional lead screw to rotate, and the two slides move towards each other, which can adjust the distance between the two pressure rollers according to the diameter of the bearing ring. The two pressure rollers squeeze the bearing ring to prevent the bearing ring from slipping on the anti-slip pad and without affecting the subsequent rotation of the bearing ring. The piston rod of the second hydraulic cylinder drives the base to move towards the rotary table. The piston rod of the fourth hydraulic cylinder drives the frame to move downward. The output shaft of the third motor drives the second bidirectional lead screw to rotate, and the two sliders move towards each other, which can adjust the distance between the two polishing rods according to the size of the bearing ring. One polishing rod is in contact with the inner side of the bearing ring, and the other polishing rod is in contact with the outer side of the bearing ring. The output shaft of the first motor drives the rotary table to rotate, and the bearing ring rotates, which can polish the inner and outer sides of the bearing ring simultaneously.

[0006] Specifically, a first guide rod is fixed inside the bracket, and both slides are provided with through holes that are adapted to the first guide rod.

[0007] By adopting the above technical solution, the setting of the first guide rod can improve the stability of the slide.

[0008] Specifically, a second guide rod is fixed inside the frame, and both sliders are provided with through holes that are adapted to the second guide rod.

[0009] By adopting the above technical solution, the setting of the second guide rod can improve the stability of the slider.

[0010] Specifically, square tubes are fixed at the four corners of the top of the base plate, and each square tube contains a column. The top of each column is connected to the support plate.

[0011] By adopting the above technical solution, the installation of square tubes and columns can improve the stability of the support plate.

[0012] Specifically, a crossbar is fixed to one side of the base, and the end of the crossbar away from the base passes through the support plate.

[0013] By adopting the above technical solution, the crossbar configuration can improve the stability of the base.
