Description

Technical Field

[0001] The utility model relates to the field of wheel assembly equipment, in particular to a bearing press riveting assembly equipment. Background Art

[0002] Generally, for wheels with relatively small diameters, such as the wheels on office chairs, medical beds, and toys, the bearing device of the wheel is adapted to rotatably support the wheel hub for mounting the wheel through a rolling bearing. For driving wheels, an inner ring rotation type is adopted, and for driven wheels, an inner ring rotation type and an outer ring rotation type are adopted. Ball bearings are widely used in this bearing device. In the prior art, the common connection method between the wheel hub of the wheel and the ball bearing is that workers manually place the wheel hub of the wheel on the positioning device of the equipment, then place the ball bearing on the inner circle of the wheel hub, and then start the equipment to press the ball bearing into the wheel hub for interference fit. In order to prevent it, the ball bearing is fixed in the wheel hub through bolts. However, using the method of manually feeding the ball bearing and the wheel hub by workers not only has low efficiency but also poses a risk of injuring the workers' palms. Fixing the ball bearing and the wheel hub by bolts also takes a lot of time, further reducing the working efficiency. Summary of the Utility Model

First, the first push plate 71 pushes the hub to the front end of the second push plate 72, and then the other first air cylinder 76 will be activated. The second push plate 72 pushes the hub onto the mold base 4. The first arc-shaped positioning groove 11 on the second push plate 72 will cooperate with the first arc-shaped positioning groove 11 to fix the hub.

At the front ends of the third push plate 81 and the fourth push plate 82 respectively, there are second arc-shaped notches 83. On the workbench 1, there are second guide rails 84 parallel to the third push plate 81 and the fourth push plate 82 respectively. On the second guide rails 84, there are second moving blocks 85 moving along the second guide rails 84. One end of the first guide rail 74 is fixed with a second air cylinder 86 for pushing the second moving block 85 to move. The third push plate 81 and the fourth push plate 82 are respectively fixed on the second moving block 85. When the first arc-shaped positioning groove 11 and the first arc-shaped positioning groove 11 cooperate to fix the hub, one of the second air cylinders 86 is activated to stack the bearing to the front end of the fourth push plate 82. Then the other second air cylinder 86 is activated, and the fourth push plate 82 will stack the bearing to the inner circle of the hub. The second arc-shaped notch 83 on the fourth push plate 82 cooperates with the second arc-shaped positioning groove 13 to fix the bearing.

[0030] A further embodiment of the second push plate 72 in the present utility model: A fixing block 12 is fixed at one end of the second push plate 72 near the first arc notch 73, and a second arc positioning groove 13 capable of being combined with the second arc notch 83 to form a circle is provided at one end of the fixing block 12.

[0031] A further embodiment of the stamping mechanism 90 in the present utility model: The stamping mechanism 90 includes a fixing frame 91 arranged on the top of the workbench 1, a third cylinder 92 is fixed on the top of the fixing frame 91 located on the top of the die base 4, a punching die 93 is fixed at the output end of the third cylinder 92, the punching die 93 is coaxial with the die base 4, a stamping and curling edge 94 is provided at the bottom of the punching die 93, and a guide rod 95 is provided on the axial center of the bottom of the punching die 93. When the second arc notch 83 and the second arc positioning groove 13 cooperate to fix the bearing, the third cylinder 92 will be activated to press the bearing into the hub and perform interference fit to fix the bearing. As Figure 6 and Figure 7 shown, two steps will be sequentially provided in the hub 200. The first step 201 will serve as a base to support the bearing 203 to prevent the bearing 203 from moving downward. The second step 202 is above the bearing 203. When the punching die 93 is inserted into the hub 200, the stamping and curling edge 94 on the bearing 203 deforms the second step 202, so that the deformed second step 202 wraps the outer edge of the bearing 203, preventing the bearing from moving upward. In this way, the bolt connection method can be replaced to further fix the bearing 203.

[0032] A further embodiment of the third push plate mechanism 100 in the present utility model: The third push plate mechanism 100 includes a third guide rail 101 arranged on the workbench 1, a third moving block 102 moving along the third guide rail 101 is provided on the third guide rail 101, a fourth cylinder 103 for pushing the third moving block 102 is fixed at one end of the third guide rail 101, a fifth push plate 104 is fixed on the top of the third moving block 102, and a semi-circular insertion block 105 is fixed at one end of the fifth push plate 104.

[0033] During use: In the initial state, the hub vibrating disc 2 and the bearing vibrating disc 3 transfer the hubs and bearings of the discs into the first flow channel 6 and the second flow channel 8 respectively by means of rotation and vibration, and then enter the first track 20 and the second track 40 through the first flow channel 6 and the second flow channel 8 respectively. The hub vibrating disc 2 and the bearing vibrating disc 3 are both prior arts, and the first flow channel 6 and the second flow channel 8 in the specification are used to indicate their working positions. The inner diameters and heights of the first flow channel 6 and the second flow channel 8 are larger than those of the hub and the bearing, so that the hub and the bearing can slide normally into the first track 20 and the second track 40. When the hub enters the first track 20, one of the first cylinders 76 will be activated. First, the hub is pushed to the front end of the second push plate 72 by the first push plate 71, and then the other first cylinder 76 is activated. The second push plate 72 pushes the hub onto the die base 4. The first arc-shaped positioning groove 11 on the second push plate 72 will cooperate with the first arc-shaped positioning groove 11 to fix the hub. After the first arc-shaped positioning groove 11 cooperates with the first arc-shaped positioning groove 11 to fix the hub, one of the second cylinders 86 is activated to stack the bearing to the front end of the fourth push plate 82. At this time, the other second cylinder 86 is activated, and the fourth push plate 82 will stack the bearing to the inner circle of the hub. The second arc-shaped notch 83 on the fourth push plate 82 cooperates with the second arc-shaped positioning groove 13 to fix the bearing. After the second arc-shaped notch 83 cooperates with the second arc-shaped positioning groove 13 to fix the bearing, the third cylinder 92 will be activated to press the bearing into the hub and perform an interference fit to fix the bearing. As Figure 6 and Figure 7 shown, two steps are sequentially provided in the hub 200. The first step 201 serves as a base to support the bearing 203 and prevent the bearing 203 from moving downward. The second step 202 is above the bearing 203. When the punching die 93 is inserted into the hub 200, the stamping crimp 94 on the bearing 203 deforms the second step 202, so that the deformed second step 202 wraps the outer edge of the bearing 203, preventing the bearing from moving upward. In this way, the bolt connection method can be replaced to further fix the bearing 203. After the stamping crimp 94 deforms the second step 202, the third cylinder 92, the second cylinder 86 and the first cylinder 76 will be reset in sequence. The fourth cylinder 103 is activated, and the hub 200 is pushed out of the die base 4 through the fifth push plate 104, so that the next hub 200 and bearing 203 can be processed continuously.
