Description

Technical Field

[0001] The utility model belongs to the technical field of rail transit, and particularly relates to an automatic bearing flipping device. Background Art

[0002] The wheel set is the part of a locomotive or vehicle that contacts the rail, and is composed of two left and right wheels firmly pressed on the same axle. The function of the wheel set is to ensure the running and steering of the locomotive or vehicle on the rail, bear all the static and dynamic loads from the locomotive or vehicle, transmit them to the rail, and transmit the loads generated by the unevenness of the line to each component of the locomotive or vehicle.

[0003] In order to reduce the burden of operators, a manipulator or other device can be used to install the bearing on the press-fitting equipment to complete the press-fitting of the bearing. Since there are strict dimensional requirements between the bearing and the wheel set, it is necessary to detect the wheel set and the bearing before press-fitting, record the parameters to form a label sticker, and stick the label on the bearing. When the manipulator grabs the bearing, it can identify the bearing according to the label. However, if the manipulator directly grabs the bearing during this process, the label will face the inside of the manipulator. If the bearing is directly installed on the press-fitting equipment, the label will be pressed onto the wheel set, thus affecting the normal installation of the bearing. Therefore, it is necessary to flip the wheel set before press-fitting so that the side with the label faces outward. If it is flipped manually, it is time-consuming and laborious, and affects the automation process of wheel set press-fitting. Summary of the Utility Model

[0004] Aiming at the problem of how to realize the automatic flipping of the bearing in the prior art, the utility model provides an automatic bearing flipping device to realize the automatic flipping during the automatic press-fitting of the bearing.

Part or all of the inner walls of the receiving groove are in contact with the arc surface of the bearing, and bearing limit members are provided around the bearing placement table.

[0007] After adopting this technical solution, a rotatable bearing placement table is provided in this technical solution for placing the bearing, and then the rotation of the bearing placement seat drives the bearing to rotate, so that the side with the label faces outward, realizing the automatic turning of the bearing, effectively saving manpower and improving the efficiency of bearing press-fitting.

[0008] Preferably, the bearing limiting member includes a bottom plate rotatably connected to the connecting seat, the bearing placement table is arranged on the bottom plate, and the bearing limiting member includes two flipping baffles arranged on the bottom plate and located on both sides of the accommodating groove in the extending direction thereof respectively.

[0009] After adopting this technical solution, the bearing is placed in the accommodating groove, and flipping baffles are arranged on both sides of the accommodating groove, so as to limit the axial displacement and radial displacement of the bearing during rotation and prevent the bearing from disengaging from the accommodating groove.

[0014] Preferably, several first bolt hole groups and several second bolt hole groups are arranged on the bottom plate. The first bearing platform is bolted to any one of the first bolt hole groups, and the second bearing platform is bolted to any one of the second bolt hole groups.

[0015] After adopting this technical solution, the relative position of the two flipping baffles can be adjusted by connecting it to any one group of bolt holes, so that the flipping baffle can just contact the end of the bearing, avoiding collision of the bearing during flipping.

[0016] Preferably, inverted L-shaped support plates are arranged on both sides of the middle of the bottom plate. The two inverted L-shaped support plates are symmetrically arranged and are located between the first bearing platform and the second bearing platform.

[0017] After adopting this technical solution, the inverted L-shaped support plates cooperate with the first bearing platform and the second bearing platform to provide a more stable supporting force for the bearing.

[0018] Preferably, the receiving groove is an axially symmetric structure.

[0019] After adopting this technical solution, the receiving groove is an axially symmetric structure. When bearings with different outer diameters are placed in the receiving groove, they can automatically slide to the middle, avoiding bearing offset, so that the mechanical gripper can smoothly grasp the bearings.

[0020] Preferably, it further includes a driving motor for driving the bearing placement seat to rotate. The driving motor is electrically connected to a controller, and the controller is electrically connected to an infrared sensor arranged in the receiving groove.

[0021] After adopting this technical solution, the infrared sensor can detect whether there is a bearing placed in the receiving groove. When it detects that a bearing is placed, the driving motor can be started through the controller to drive the bearing placement seat to rotate.

The bearing is placed in the receiving groove, and the flip baffles 4 are arranged on both sides of the receiving groove, so as to limit the axial displacement and radial displacement of the bearing during the rotation process, and prevent the bearing from leaving the receiving groove.

[0036] In this embodiment, an arc groove 5 is provided at the top of the flip baffle 4 corresponding to the bearing hole, and the shape of the arc groove 5 matches the shape of the bearing hole. If the flip baffle 4 is too high, it will affect the gripping and placement of the manipulator, and if the flip baffle 4 is too low, the bearing may be separated from the bearing placement platform during the rotation process. Therefore, the end of the flip baffle 4 can be slightly beyond the bearing hole. By providing the arc groove 5, the bearing hole is exposed, which facilitates the positioning assembly on the mechanical gripper to be positioned through the bearing hole.

[0037] In this embodiment, the bearing placement platform is composed of a first bearing platform 3 and a second bearing platform 7.

In this embodiment, several first bolt hole groups and several second bolt hole groups are provided on the bottom plate 2. The first carrier 3 is bolted to any one of the first bolt hole groups, and the second carrier 7 is bolted to any one of the second bolt hole groups. The movable connection is achieved by bolt connection. By setting both the first carrier 3 and the second carrier 7 to be movably connected to the bottom plate 2, the first carrier 3 and the second carrier 7 can be moved outward or inward by the same distance, ensuring that the center of gravity of the bearing placement seat does not shift and ensuring the stability of rotation. On both sides of the middle of the bottom plate, inverted L-shaped support plates 8 are provided. The two inverted L-shaped support plates 8 are symmetrically arranged, and the inverted L-shaped support plates 8 are located between the first carrier 3 and the second carrier 7.
