Description

Technical Field

[0001] The utility model relates to a roller bar sorting device for bearing steel balls, belonging to the technical field of steel ball sorting. Background Art

[0002] Bearing steel balls are important mechanical parts with advantages such as high precision, high hardness and good wear resistance. During the processing of bearing steel balls, some defects may occur, such as surface roughness and dimensional deviation. Therefore, in order to ensure the quality of bearing steel balls, sorting is usually required. However, the roller sorting device is an effective sorting method that can accurately sort the steel balls according to their size and shape.

[0003] The utility model with patent number 202322203638.2 provides a roller bar sorting device for bearing steel balls. The roller bar sorting device for bearing steel balls, through the design of a noise reduction chamber and a sound insulation board, can effectively reduce the generation and spread of noise by setting the roller bar sorting device in the noise reduction chamber. The sound insulation board arranged on the inner wall of the noise reduction chamber can absorb and block the noise generated during the operation of the device, provide a quieter working environment, protect operators from the harm of noise, and improve work efficiency and comfort; however, the existing roller bar sorting device allows the steel balls to roll between two rollers. The position is narrow when loading at will, which makes it easy for the steel balls to be blocked. Moreover, the steel balls themselves are heavy. After reaching the sorting position, they fall down and collide with other steel balls or storage boxes, resulting in marks on the surface, affecting the subsequent use of the bearing steel balls. Utility Model Content

[0004] In view of the problems in the related art, the present invention proposes a roller bar sorting device for bearing steel balls to overcome the above technical problems existing in the existing related art.

[0007] Preferably, the loading plate and the roller assembly are both tilted, a fixing rod is fixed on the fixing frame, and the bottom of the loading plate is slidably connected to the fixing rod via a sliding block.

[0008] Preferably, a rotating disk is fixedly provided on the output shaft of the stepping motor, and connecting protruding rods are fixedly provided on one side of the top of the rotating disk and the bottom of the loading plate, and the connecting protruding rods are connected by a driving rod.

[0009] Preferably, a baffle is fixedly provided on the edge of the loading plate, and a loading hopper is fixedly provided on the bottom right side of the loading plate, and the position of the loading hopper corresponds to the position of the roller assembly.

[0010] Preferably, screw rods are symmetrically rotated at both ends of the fixing seat, movable blocks are sleeved on the screw rods, both ends of the adjusting roller are hinged to the movable blocks respectively, and a rotating handle is provided at one end of the screw rods.

[0011] Preferably, a driving motor is fixedly mounted on the bottom of the fixing seat, and pulleys are fixedly provided on the output shaft of the driving motor and the right end of the fixed roller, and the pulleys are connected by a synchronous belt.

[0012] Preferably, the distribution hoppers are all funnel-shaped, the tops of the buffer plates are hinged to the inner walls of the distribution hoppers, the bottoms of the buffer plates are connected to the inner walls of the distribution hoppers via buffer springs, and rubber pads are fixed on the surfaces of the buffer plates and the inner walls of the distribution hoppers.

[0013] Preferably, baffles are fixedly provided between the distribution hoppers, and the baffles are located below the roller bar assembly. A material guide plate is obliquely provided at the bottom of the distribution hopper, and the material guide plate extends to the inner cavity of the distribution box.

[0014] The beneficial effects of the utility model are:

[0015] By setting up a loading plate, when in use, the bearing steel balls are placed on the loading plate, and the loading plate can be driven by a stepper motor to shake left and right, so that the bearing steel balls move back and forth on the loading plate, and the bearing steel balls can be dispersed and evenly fall on the two roller assemblies, thereby avoiding the blockage of the bearing steel balls and improving the efficiency of bearing steel ball sorting;

[0016] By setting the roller assembly, the bearing steel ball slides to the right on the roller assembly. As the gap between the two rollers increases, bearing steel balls of different diameters can fall at different positions. At the same time, the roller can be adjusted to move by the screw rod, thereby changing the gap between the roller assemblies, thereby increasing the applicability of bearing steel ball sorting.

[0017] By setting up a sorting hopper, when the bearing steel balls fall downward, they will first enter the sorting hopper. The buffer plate can cushion the impact of the falling bearing steel balls, and then they will slowly slide into the sorting box to directly collect the sorted bearing steel balls, thereby avoiding surface marks on the bearing steel balls due to collisions.
