Description

Technical Field

[0001] The utility model relates to a surface treatment device for a bearing inner ring, belonging to the technical field of bearing inner ring processing. Background Art

[0002] The bearing is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Rolling bearings are generally composed of four parts: an outer ring, an inner ring, a rolling element, and a cage. According to the shape of the rolling element, rolling bearings are divided into two categories: ball bearings and roller bearings. Patent No. CN202120262998.8 discloses a surface treatment device for the inner ring of a bearing, including an upper cover and a treatment box. The upper cover is hinged at the upper end of the treatment box. The left and right parts of the treatment box are fixed with bearing seats by screws. A rotating rod passes through the bearing seat, and a grinding disc is fixed to the other end of the rotating rod by screws. A fixed seat is movably installed in the middle of the treatment box, and a bidirectional motor is fixed in the upper part of the fixed seat. The utility model uses a fixed seat, a bidirectional motor, a screw rod, an upper positioning piece and a lower positioning plate to quickly support and fix the inner ring. The operation is simple and the stability of the effective inner ring fixation is ensured. At the same time, the inner ring is fixed vertically, which is convenient for grinding. The need to adjust the position of the inner ring after disassembly is avoided, thereby improving work efficiency.

[0003] The above-disclosed bearing inner ring surface treatment device has the disadvantage that it cannot clean the inner ring surface of the bearing inner ring when treating the bearing inner ring surface, and needs to be treated one by one separately. In addition, during the treatment process, the waste chips generated cannot be collected quickly and effectively. For this reason, we design a bearing inner ring surface treatment device.

The bearing inner ring transmission belt 2 is arranged in the internal channel of the bearing inner ring processing shell 1 through a mounting bracket. A gear protection cover 12 is installed on one side of the top of the bearing inner ring processing shell 1. The servo drive motor 11 is arranged on the top of the gear protection cover 12 through a motor bracket, and the rotation direction of the output shaft of the servo drive motor 11 is clockwise and counterclockwise. Three transmission meshing gears 8 are installed inside the gear protection cover 12. A transmission meshing gear 8 located on one side is keyed to the output end of the servo drive motor 11. The bottom ends of the three transmission meshing gears 8 are connected to the transmission sleeve rod 6 through a mounting plate. The interiors of the three transmission sleeve rods 6 are all installed with piston telescopic rods 15, and one end of the three piston telescopic rods 15 is installed with an inner ring surface cleaning brush strip 7;

[0021] In this embodiment, if Figure 2As shown, a group of electric push rods 4 are installed on both sides of the inner cavity of the bearing inner ring processing shell 1, and the telescopic ends of the two groups of electric push rods 4 are installed with bearing inner ring clamping strips 3. The ends of the two bearing inner ring clamping strips 3 are provided with bearing limit bending strips, and the bottom end of the bearing inner ring processing shell 1 is installed with a track groove corresponding to the upper and lower gear protection cover 12, and the waste collection mesh plate 5 is slidably set at the bottom end of the bearing inner ring processing shell 1 through the track groove.

[0022] The above-mentioned structural design: using two bearing inner ring clamping strips 3 and the bearing limit bending strips can simultaneously clamp the three bearing inner rings, and at the same time have a good limiting effect to prevent the bearing from shaking during the cleaning process. The waste collection mesh plate 5 is provided to facilitate the collection of waste generated by cleaning, and is easy to use.

[0023] In this embodiment, if Figure 3 As shown, an air compression pump 13 is installed in the middle of the bearing inner ring processing shell 1, and a three-way control valve 14 is installed at the output end of the air compression pump 13. One output end of the three-way control valve 14 is connected to the air eyes of three transmission sleeve rods 6 through an air pipe; the other output end of the three-way control valve 14 is connected to a blowing window strip 16 through an air pipe, and the blowing window strip 16 is connected to the bearing inner ring processing shell 1 and corresponds to the bearing inner ring clamping strip 3.

[0024] The above structural design: on the one hand, the piston telescopic rods 15 of the three transmission sleeves 6 are telescopically controlled by the air compression pump 13, and on the other hand, the air compression pump 13 is used to blow air through the blowing window strips 16 to facilitate cleaning the surface of the bearing inner ring transmission belt 2.

[0025] In this embodiment, if Figure 2 As shown, in order to prevent the bearing inner ring from falling during transportation, bearing anti-falling bars 9 are arranged on both sides of the bearing inner ring transmission belt 2, and one end of the two bearing anti-falling bars 9 is respectively connected to the two bearing inner ring clamping bars 3.

[0026] The bearing inner ring transmission belt 2 is a transmission belt structure of the prior art, which is assembled from a transmission roller and a roller frame, a motor, a position sensor and a transmission belt.

[0028] Working principle: put the inner ring of the bearing into the bearing inner ring transmission belt 2 through the bearing inner ring insertion port 10, and use the transmission effect of the bearing inner ring transmission belt 2 to transmit the bearing to the bearing limit bending strips of the two bearing inner ring clamping strips 3. After the two sets of electric push rods 4 are energized, the two bearing inner ring clamping strips 3 perform side limit extrusion on the bearing inner ring to achieve a clamping effect. At this time, the air compression pump 13 controls the piston telescopic rod 15 of the three transmission sleeve rods 6 to extend and retract, so that the inner ring surface cleaning brush strip 7 contacts the inner ring surface of the bearing inner ring. The servo drive motor 11 drives the three transmission meshing gears 8 to rotate, and the inner ring surface cleaning brush strip 7 is driven to rotate through the transmission meshing gears 8, so that the inner ring surfaces of the three bearing inner rings clamped between the bearing inner ring clamping strips 3 can be cleaned. The three bearing inner rings can be cleaned at one time without separate processing, which is very convenient and greatly improves the processing efficiency.

[0029] Among them, during the rotation of the transmission meshing gear 8, one cycle is that the transmission meshing gear 8 rotates one circle and then reverses one circle. After multiple cycles of rotation, the inner ring of the bearing can be effectively cleaned.

[0030] The size of the transmission meshing gear 8 is designed to be approximately equal to the size of the bearing to be cleaned.
