[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The present invention provides a bearing installation device for a transport vehicle. The bearing can be placed horizontally on the outer ring of the roller through a bearing pushing mechanism to ensure that the subsequent clamping process can be carried out normally. At the same time, the retaining ring installation station includes a tapered sleeve and an expansion pressure head. The retaining ring is first placed horizontally in the tapered sleeve through the retaining ring pushing mechanism, and the retaining ring is pressed horizontally in the tapered sleeve with the expansion pressure head. During the pressing process, the retaining ring gradually shrinks and finally expands when it reaches the retaining ring installation groove point on the outer ring of the roller to complete the installation. The overall structure is simple, the operation is convenient, and it saves time and effort.

[0021] (2) The bearing pushing mechanism includes a first guide rail, a bearing support plate and a bearing push plate. The front part of the bearing support plate extends into the bottom of the bearing push plate and is connected to the bearing push plate through a connecting column. When the bearing support plate is extended, the connecting column moves in the through groove, and the part of the bearing support plate extending into the bearing push plate extends while the bearing push plate does not move. When the connecting column reaches the end of the through groove, it starts to push the bearing push plate. At this time, the front end of the bearing support plate is located under the bearing to play a supporting effect, ensuring that the bearing can be placed stably on the outer ring of the roller; and when the bearing needs to be returned after being completely pushed out, the first drive first drives the bearing support plate to move. After the bearing support plate is completely withdrawn from under the bearing, the bearing is placed horizontally and stably on the outer ring of the roller, and then the connecting column reaches the end of the through groove, thereby driving the bearing push plate to return and restore to the initial state. The structure is simple and the function is practical, ensuring the smooth placement of the bearing and avoiding the damage of the workpiece due to the uneven placement of the bearing.

[0022] (3) The bearing pressure head is provided with an annular protrusion and a cylindrical protrusion. The annular protrusion can be stuck on the edge of the bearing to apply pressure to avoid squeezing the ball and causing damage to the bearing. The cylindrical protrusion can penetrate into the center of the bearing to play a positioning role and ensure the pressing effect.

[0023] (4) The retaining ring pushing mechanism has the same structure as the bearing pushing mechanism. The retaining ring pushing plate plays a supporting role when pushing out the retaining ring, ensuring that the retaining ring is placed horizontally in the tapered sleeve. The inner diameter of the tapered sleeve gradually decreases from top to bottom, and the expansion pressure head can make the retaining ring gradually shrink during the horizontal downward pressure process; the lower end of the tapered sleeve is provided with an annular pressing sleeve, which can be clamped on the outer ring of the roller to play a positioning role. At the same time, the inner diameter of the lower end of the tapered sleeve is equal to the inner diameter of the outer ring of the roller. After the retaining ring is pressed into the outer ring of the roller, it automatically rebounds and expands after being separated from the tapered sleeve, and is clamped into the retaining ring groove of the outer ring of the roller to achieve installation.

[0024] (5) A step is provided on one side of the guide block to facilitate the entry of the retaining ring push plate; the other side is tightly connected with the tapered sleeve to prevent the retaining ring from falling out. When the retaining ring push plate pushes the retaining ring out, it first enters the guide block, and the guide block limits the retaining ring to ensure that the retaining ring is in a horizontal position, ensuring that the retaining ring is subjected to stable force when the expansion pressure head is pressed down, and preventing the retaining ring from falling out or deflecting; the vertical gap provided at the bottom of the expansion pressure head can cause its diameter to change during the pressing process, ensuring that it can press on the outer edge of the retaining ring to press it horizontally.

[0025] (6) The guide plate can adjust the fallen outer ring of the roller to a horizontal level to facilitate subsequent processing; the shifting mechanism can realize automatic position change of the workpiece to improve efficiency. Combined with sensors and control systems, it can realize automatic assembly line processing, reduce the labor intensity of workers, and improve installation efficiency and quality.

[0026] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention, it can be implemented in accordance with the contents of the specification. In order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, the following preferred embodiments are specifically cited and described in detail as follows.

[0065] When the present invention is in use, the roller outer ring 400 slides down from the roller outer ring bracket 200, and after being adjusted by the guide plate 210, the roller outer ring 400 turns to the horizontal position, the longitudinal driving member 920 controls the shifting card plate 930 to move forward and clamp the roller outer ring 400 against the positioning bar 1000, and the transverse driving member 910 controls the shifting card plate 930 to move transversely and move the roller outer ring 400 to the bottom of the bearing installation station 500;

[0066] After the sensor detects that the roller outer ring 400 is in place, the bearing pushing mechanism 520 pushes the bearing 610 dropped by the bearing guide ring 600 onto the roller outer ring 400. Specifically, the output end of the first drive 523 extends to push the bearing support plate 522 forward, and the connecting column 522a moves in the through groove 524a. The part of the bearing support plate 522 extending into the bearing push plate 524 extends while the bearing push plate 524 does not move. When the connecting column 522a reaches the end of the through groove 524a, it starts to push the bearing push plate 524. At this time, the front end of the bearing support plate 522 is located below the bearing 610 to support it. The bearing push plate 524 pushes the bearing 610 After the bearing 610 is pushed onto the outer ring 400 of the roller, the sensor detects that the bearing 610 is in place, and the bearing pressure head 512 is pressed down, and the cylindrical protrusion 512a provided on the bearing pressure head 512 extends into the center of the bearing 610 for positioning, and then the first drive 523 drives the bearing support plate 522 to withdraw, and after the bearing support plate 522 is completely withdrawn from under the bearing 610, the bearing 610 is placed horizontally and stably on the outer ring 400 of the roller, and finally the connecting column 522a reaches the end of the through groove 524a, thereby driving the bearing push plate 524 to withdraw and return to the initial state, and the bearing pressure head 512 is pressed down to press the bearing 610 horizontally and stably into the outer ring 400 of the roller;

[0067] The shift mechanism 900 moves the workpiece. Specifically, the longitudinal drive member 920 controls the shift card plate 930 to move backward, and then the transverse drive member 910 controls the shift card plate 930 to move horizontally one station to the left. The longitudinal drive member 920 controls the shift card plate 930 to move forward again and clamp the outer ring of the roller. Finally, the transverse drive member 910 controls the shift card plate 930 to move the outer ring 400 of the roller installed in the bearing 610 horizontally to the bottom of the retaining ring installation station 700. At the same time, the shift card plate 930 also moves the new outer ring 400 of the roller under the guide plate 210 to the bottom of the bearing installation station 500.

[0068] After the sensor detects that the roller outer ring 400 is in place, the lifting drive 741 controls the horizontal plate 740 to move down to the annular pressing sleeve 711 at the lower end of the tapered sleeve 710 and sleeves it on the roller outer ring 400. Then the retaining ring pushing mechanism 720 is actuated to push out the retaining ring 810. The specific action is the same as that of the bearing pushing mechanism 520. After the retaining ring 810 is pushed out, it is located in the guide block 760. After the retaining ring support plate 720 is retracted, the retaining ring 810 falls horizontally into the tapered sleeve. Then the retaining ring pressing drive 750 presses down and drives the expansion pressure head 730 to move in the tapered sleeve 710. The retaining ring 810 moves, and its diameter is continuously reduced due to the upper pressure in the tapered sleeve 710, and finally enters the roller outer ring 400 at the lower end of the tapered sleeve 710. The expansion pressure head 730 continues to press down, and the retaining ring 810 enters the retaining ring installation groove of the roller outer ring 400 and then loosens and expands, and is stuck in the roller retaining ring 810 to complete the installation; finally, the shifting mechanism 900 removes the installed workpiece, which can be collected manually or transmitted by a conveyor belt, thereby realizing the streamlined automatic installation of the bearing, reducing the labor intensity of workers and improving the installation efficiency and quality.
