Description

Technical Field

[0001] This utility model relates to the field of automated assembly technology of bearing locking rings, specifically to a semi-automatic locking ring assembly device based on cylinder drive for bearing locking ring assembly. Background Technology

[0002] Currently, when installing bearing retaining rings, most retaining rings require workers to first pry them open before attaching them to the bearing workpiece. This manual installation is inefficient and cannot guarantee production capacity. Most domestic bearing manufacturers currently assemble retaining rings manually using tools. This involves high labor intensity for workers, and the retaining rings are prone to flying off during assembly, potentially causing injury. Furthermore, due to the weight of the workpieces, workers may lose their grip during assembly. If the workpiece slips from their hands, it could fall and injure the worker, or it could damage the product, leading to substandard product quality and a low yield rate. Utility Model Content

[0027] like Figure 1 As shown, this utility model discloses a semi-automatic locking ring installation device based on cylinder drive, including a frame 9, a spreading mechanism, and a lifting mechanism.

[0028] like Figure 1 , 2 As shown in Figure 3, the opening mechanism includes an outer shell 11, an inner shell 10, a top head 3, a limiting spring 2, an opening claw 1, a connecting plate 12, an upper cylinder 4, and a cylinder 13. The inner shell 10 is fixed inside the outer shell 11, and the bottom ends of both the inner shell 10 and the outer shell 11 are fixed to the upper part of the connecting plate 12. The connecting plate 12 is connected to the frame 9. An even number of grooves are evenly provided on the inner shell 10 for engaging the opening claw 1. The opening claw 1 can move horizontally along the grooves. A limiting spring 2 is provided between the opening claw 1 and the outer shell 11. The upper part of the top head 3 is located in the middle of the inner shell 10, and the lower part is located in the groove on the upper part of the cylinder 13. The bottom end of the top head 3 is connected to the piston rod of the upper cylinder 4. The upper part of the cylinder 13 is connected to the lower part of the connecting plate 12, and the cylinder 4 is installed on the lower part of the cylinder 13.

[0029] like Figure 4As shown, the spreading claw 1 consists of two parts, upper and lower. The upper support column has an inverted trapezoidal cross-section and a stepped top for easy installation of the locking ring. The lower base has protrusions on both sides along the circumferential direction near the top head 3 to restrict the displacement of the spreading claw 1 in the horizontal direction. In addition, the side of the lower base of the spreading claw 1 opposite to the top head 3 is inclined and parallel to the inclined surface of the top of the top head 3.

[0030] like Figure 5 As shown, the top of the mandrel 3 has multiple inclined surfaces, the number of which is the same as the number of the opening claws 1. The mandrel 3 has a groove in the center, which is used to position the workpiece.

[0031] like Figure 2 , 3 As shown, the lifting mechanism includes a connecting plate 7, a connecting rod 6, a lower cylinder 5, and a top plate 8. The lower cylinder 5 is installed below the upper cylinder 4, and the piston rod of the lower cylinder 5 is connected to the bottom connecting plate 7. Two connecting rods 6 are installed on the connecting plate 7. The connecting rods 6 pass through the cylinder 13 and the inner shell 10 in sequence and are then fixed to the top plate 8. The top plate 8 is located above the inner shell 10, and multiple grooves are provided on the inner side of the top plate 8 for the support column of the upper part of the claw 1 to pass through.

[0032] Upper cylinder 4 is controlled by switch 1, and lower cylinder 5 is controlled by switch 2. Switches 1 and 2 are manually controlled.

[0033] The method of using a semi-automatic locking ring installation device based on cylinder drive according to this utility model is as follows: In the initial position, the opening mechanism is in the retracted state (i.e., the limit spring 2 is in the released state). Place the locking ring at the opening claw 1, press switch 1, the piston rod of cylinder 4 extends, driving the top head 3 to rise. The top head 3 hits the opening claw 1, opening the opening claw 1. At this time, place the workpiece in the groove of the top head 3, ensuring the coaxiality of the workpiece and the device. Press switch 2, the piston rod of cylinder 5 extends, driving the connecting rod 6 to rise through the connecting plate 7. The top plate 8 rises simultaneously, thereby pushing out the locking ring. At this time, the locking ring is assembled onto the workpiece (see...). Figure 6 Once installation is complete, remove the workpiece; then press switch 1 to open claw 1 and return it to its original position under the action of limit spring 2. Press switch 2 to return the lifting mechanism to its original position. This completes one cycle.

[0034] This utility model discloses a semi-automatic lock ring loading device based on cylinder drive, which realizes semi-automatic assembly. Workers only need to complete the lock ring loading, workpiece positioning, and switch operation without continuous force application. One person can operate 1-2 machines at the same time, increasing the daily assembly volume to 800-1000 pieces, which is 3-4 times more efficient than manual assembly, meeting the needs of large-scale production of enterprises. The machine replaces the manual direct contact of the lock ring opening action: the opening mechanism is driven by the upper cylinder, and the worker does not need to use hand tools to apply force. The risk of the lock ring flying off is reduced from 5% in manual assembly to less than 0.1%. The worker's operation only involves three simple actions: "loading - pressing the switch - picking up the part". There is no need to apply continuous force or carry heavy objects. The labor intensity is reduced by more than 80% compared with manual assembly, which can reduce occupational injuries and improve the worker's operating comfort and production enthusiasm.

[0035] The embodiments described above are preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Any obvious improvements, substitutions or modifications that can be made by those skilled in the art without departing from the essential content of the present invention shall fall within the protection scope of the present invention.
