Technical Field

[0001] The utility model belongs to the technical field of bearings, and particularly relates to a bearing roller clamping mechanism. Background Art

[0002] At present, the horizontal transportation of roller bearings is mostly used for the transportation of guide rail cylinders. Limited by the influence of the force arm and clamping force, only short rollers and small-weight rollers can be clamped; there is currently no practical transportation mechanism for large-size and large-weight rollers. Therefore, how to solve the transportation of large-size and large-weight rollers has become a problem to be solved urgently. Summary of the Invention

[0003] In order to solve the above technical problems, a bearing roller clamping mechanism is provided.

[0006] The rotary slide of the rotary cylinder I is connected to the rotary cylinder II through a transition plate.

[0016] The present utility model will be described in detail in combination with the accompanying drawings and specific embodiments:

[0017] As Figure 1 and Figure 2 shown, a bearing roller clamping mechanism has a rotary cylinder II 3; the rotary cylinder II 3 is a thin cylinder, and its output shaft is located in the middle of the lower end face of the rotary cylinder II 3; the output shaft of the rotary cylinder II 3 is connected with a gear 7; there are two racks 8 meshing with the gear 7 and symmetrically arranged relative to the gear; the two racks 8 are respectively fixed on the corresponding rack fixing seats 9; the two rack fixing seats 9 are respectively matched with the guide rail fixing seat 4 connected to the body of the rotary cylinder II 3 through a linear guide rail 10, forming a structure in which the rotation of the output shaft of the rotary cylinder II drives the gear to rotate, thereby driving the two racks to move linearly; in combination with Figure 3 , the cross-sectional shape of the rack fixing seat 9 is L-shaped; the lower end face of each rack fixing seat 9 has a card slot for cooperating with the claw; the claw 5 is L-shaped; the two claws 5 are arranged symmetrically in the reverse direction; the two claws together form a clamping structure for clamping the bearing roller; the bearing roller clamping mechanism is also provided with a rotary cylinder I 1 for driving the rotary cylinder II and the bearing roller to rotate.

[0018] The rotary slide table 11 of the rotary cylinder I 1 is connected with the rotary cylinder II through a transition plate.

[0019] The guide rail fixing seat 4 is of H-shaped structure.

[0020] A jaw pad 6 for direct contact with the bearing roller is installed on the jaw.

[0021] The rotating cylinder I 1 is a swing cylinder with an adjustable swing angle and a flat mounting surface; the rotating cylinder II is a thin type shafted cylinder with an output shaft as the transmission form and an adjustable output stroke; the rack fixing seat fixes the rack and the linear guide. When the rotating cylinder drives the gear to rotate, the rack fixing seat moves horizontally in a straight line. There is an additional U-shaped notch for fixing the jaw; the jaw is fixed on the rack fixing seat and moves together with the rack fixing seat. When the two jaws move, they are symmetric about the center of the gear; the jaw pad is fixed on the jaw for contacting the roller. The material is polyurethane and will not scratch the roller during contact with the roller; the gear-rack meshing is a standard straight tooth with a module of 1.5 and a pressure angle of 20°.

[0022] The rotating shaft of the rotating cylinder II drives the gear to rotate axially. The gear drives the rack and the jaw to perform a linear motion to complete the clamping and opening actions. The rotating cylinder I drives the lower component to rotate to complete the angle conversion of the roller, as Figure 5 、 Figure 6 。

[0023] The main dimensions of the roller mainly include the roller length L and the roller diameter D; for the range of the length L, this mechanism can change the size of the gear diameter of No. 7 to set the opening distance L1 of the jaws (two) of No. 5 (that is, the larger the gear, the greater the linear stroke transmitted to the jaws when rotating one circle). As long as L1 > L, the jaws can effectively hold and transport the roller in the clamped state; for the range of the diameter D, this mechanism can change the length of the jaws of No. 5 to ensure that the roller with the largest diameter does not interfere with the gear of No. 7 and the rack fixing seat of No. 9.
