Description

Technical Field

[0001] The invention relates to the technical field of roller bearing assembly, in particular to full complement roller bearing assembly equipment. Background Art

[0002] Roller bearing is a radial bearing with a thick-section outer ring, which can be used as a wheel to roll on the guide rail. Its main function is to support the rotating shaft and parts on the shaft, and maintain the normal working position and rotation accuracy of the shaft, while reducing friction loss and improving mechanical efficiency. The working principle of roller bearing is to transmit force and motion through the rolling of rolling elements (such as balls or rollers) between the inner ring and the outer ring, thereby converting sliding friction into rolling friction, greatly reducing friction resistance and energy consumption. In addition, roller bearings also have the advantages of compact structure, light weight, high precision, large load, low wear and long service life, and are widely used in various mechanical equipment.

[0003] The existing roller bearings are composed of an outer ring, a cage, a needle roller and an inner ring. The roller bearings are generally assembled by a press or manually. However, there are the following difficulties when assembling the roller bearings:

[0004] Due to the special structure of the roller bearing, the ribs at both ends are different, and the needle rollers cannot be installed on one side, but can only be installed from one side. Therefore, it will be hindered during assembly, resulting in low assembly efficiency and difficult assembly operation.

[0090] The inner ring of the bearing is installed on the inner side of the retaining frame, and the outer wall of the inner ring of the bearing is clamped by a plurality of groups of needle rollers.

[0091] The operation method of the full complement roller bearing assembly equipment includes the following steps:

[0092] S1: Place the outer ring of the bearing on the surface of the outer ring conveying platform, place the cage on the surface of the cage conveying assembly, place the needle roller inside the screw feeder, and place the inner ring of the bearing on the surface of the inner ring conveying assembly;

[0093] S2: Start the outer ring conveying platform to transport the outer ring of the bearing to the rightmost end, start the outer ring transfer assembly to clamp the outer ring of the bearing, rotate the outer ring of the bearing to the right end, and place the outer ring of the bearing on the surface of the movable column. At this time, start the hydraulic cylinder to extend the expansion block, so that the expansion block can fix the outer ring of the bearing, and then retract the expansion block to the inside;

[0094] S3: By starting the first drive motor, the movable column is moved to the right end of the lateral limit box, and the movable column is at a right angle to the cage conveying mechanism and the needle roller conveying mechanism. At this time, the cage conveying assembly is started to move the cage to the front end of the cage conveying assembly, and the cage transfer assembly is started to transfer the cage clamping to the upper end of the movable column, and the clamping of the cage transfer assembly is released, so that the cage is placed on the top of the outer ring of the bearing. The limit column is driven to rise by starting the second drive motor, and the hydraulic cylinder is started to fix and limit the position of the cage by the expansion block. Then, the limit column is raised again by retracting the expansion block, so that the bottom of the expansion block is higher than the top of the cage. At this time, the expansion block is unfolded, and the second drive motor is started again to drive the limit column to descend. At this time, the bottom of the expansion block contacts the top of the cage, and the cage is pressed by the rotation and descent of the expansion block, so that the cage is assembled to the inside of the outer ring of the bearing, so that the second outer ring rib at the bottom of the outer ring of the bearing contacts the bottom of the cage, and the bottom of the first outer ring rib blocks and limits the top of the cage;

[0095] S4: At this time, the motor is started to drive the first screw to rotate, so that the lateral moving assembly drives the movable column to rise until the inner notch of the retaining frame and the output port of the conveying track are on the same horizontal plane, and the spiral feeder is started to transport the needle roller to the inside of the conveying track, and the needle roller is rolled out through the guidance of the conveying track. At this time, the fourth driving motor is started to drive the first half gear and the second half gear to rotate intermittently, thereby driving the pressing mold to rotate intermittently, so that the pressing mold receives the needle roller that slides out, and presses the needle roller to the inside of the inner notch of the retaining frame, and the inner notch limits the installed needle roller. At the same time, the position of the retaining frame is fixed intermittently in cooperation with the telescopic drive of the expansion block to prevent the retaining frame from being displaced. At the same time, the continuous rotation of the pressing mold drives the retaining frame to rotate, so that the needle roller moves to the side, which is convenient for the installation of the next group of needle rollers. The installation steps of the needle rollers are repeated until the needle rollers are completely installed;

[0096] S5: The first screw is driven to rotate by starting the motor, and the movable column is driven to descend to the inner ring conveying mechanism. At this time, the assembled outer ring of the bearing is moved to the storage platform for storage by clamping the inner ring transfer component. At the same time, the inner ring conveying component is started, and the inner ring of the bearing is clamped to the top of the movable column by the inner ring transfer component, and the position of the inner ring of the bearing is corrected by the extension block. At the same time, the extension block rises, so that the bottom of the extension block presses and limits the top of the inner ring of the bearing. At this time, the movable column continues to descend, and the inner ring transfer component is started again, so that the inner ring transfer component clamps and transfers the temporarily stored assembled outer ring of the bearing to the upper end of the inner ring of the bearing. By raising the movable column again, the limit column penetrates the assembled outer ring of the bearing, so that the bottom of the needle roller contacts the top inclined surface of the extension block. Through continuous extrusion, the bottom of the needle roller slides into the outer wall of the inner ring of the bearing through the inclined surface of the extension block, so that several groups of needle rollers are squeezed against the outer wall of the inner ring of the bearing, thereby completing the assembly of the roller bearing mechanism.

[0097] Compared with existing technologies:

[0098] Through the coordination of the assembly mechanism, the outer ring conveying mechanism, the cage conveying mechanism, the needle conveying mechanism and the inner ring conveying mechanism, the various components of the roller bearing mechanism can be continuously transported, and at the same time, through motion coordination, the various components of the roller bearing mechanism can be assembled, thereby mechanizing the assembly operation, reducing the manual participation of the assembly operation, simplifying the assembly, and preventing obstacles from occurring during assembly, thereby improving the efficiency of the assembly and reducing the difficulty of the assembly operation.

At this time, start the hydraulic cylinder (241) to extend the expansion block (244), so that the expansion block (244) can fix and limit the placed bearing outer ring (711), and then retract the expansion block (244) to the inside; S3: By starting the first drive motor (133), the movable column (211) is moved to the right end of the lateral limit box (131), and the movable column (211) is in a right angle state with the retainer conveying mechanism (4) and the needle conveying mechanism (5). At this time, by starting the retainer conveying assembly (41), the retainer (72) is moved to the front end of the retainer conveying assembly (41), and the retainer transfer assembly (42) is started to clamp and transfer the retainer (72) to the upper end of the movable column (211), and the clamping of the retainer transfer assembly (42) is released to place the retainer (72) on the top of the bearing outer ring (711), and the limit column (234) is driven to rise by starting the second drive motor (222), and the hydraulic cylinder (241) is started to make the expansion block (244) move to the retainer. The holder (72) is fixed and limited in position, and then the expansion block (244) is retracted and the limiting column (234) is raised again so that the bottom of the expansion block (244) is higher than the top of the holder (72). At this time, the expansion block (244) is unfolded, and the second drive motor (222) is started again to drive the limiting column (234) to descend. At this time, the bottom of the expansion block (244) contacts the top of the holder (72), and the expansion block (244) is rotated and descended to press the holder (72), so that the holder (72) is assembled to the inside of the bearing outer ring (711), so that the second outer ring rib (713) at the bottom of the bearing outer ring (711) contacts the bottom of the holder (72), and the bottom of the first outer ring rib (712) blocks and limits the top of the holder (72); S4: At this time, the motor is started to drive the first screw (122) to rotate, so that the lateral moving assembly (13) drives the movable column (211) to rise until the inner notch of the retaining frame (72) and the output port of the conveying track (512) are on the same horizontal plane, and the spiral feeder (511) is started to transport the needle roller (73) to the inside of the conveying track (512), and the needle roller (73) is rolled out through the guidance of the conveying track (512). At this time, the fourth drive motor (525) is started to drive the first half gear (523) and the second half gear (526) to rotate intermittently, thereby driving the pressing mold (521) The pressing mold (521) is intermittently rotated to receive the sliding needle roller (73) and press the needle roller (73) into the inner groove of the retaining frame (72), so that the inner groove limits the installed needle roller (73). During the installation, the retaining frame (72) is intermittently fixed in position in cooperation with the telescopic drive of the expansion block (244) to prevent the retaining frame (72) from being displaced. At the same time, the pressing mold (521) is continuously rotated to drive the retaining frame (72) to rotate, so that the needle roller (73) moves to the side, which is convenient for the installation of the next group of needle rollers (73). The installation steps of the needle rollers (73) are repeated until the needle rollers (73) are completely installed. S5: The first screw rod (122) is driven to rotate by starting the motor, and the movable column (211) is driven to descend to the inner ring conveying mechanism (6).
