Description

Technical Field

[0002] A wheel hub is a cylindrical metal part that supports the tire inside the tire contour and is centered on the shaft. It is also called a rim, steel rim, wheel or tire bell. There are many types of wheel hubs according to diameter, width, forming method and material.

[0003] During the production process of the wheel hub, different conveying systems are required. Among them, the wheel hub ground chain conveyor line is a conveyor line used for jet processing of the wheel hub. This type of conveyor line drives the bracket to move through the chain. The bracket is separated from the ground and is externally provided with gears. When the bracket moves to the painting section, the gears mesh with the equipment in the painting section, causing the bracket to rotate, thereby realizing the all-round painting operation of the wheel hub.

[0004] In the above-mentioned conveying system, since the overall weight of the wheel hub is heavy, when the wheel hub is set above the bracket, the center of gravity of both the bracket and the wheel hub is relatively high. Therefore, the wheel hub will shake during transportation, which is not stable enough. Therefore, a wheel hub conveying system is proposed to solve the above-mentioned problems. Summary of the Utility Model

It should also be understood that the terms "comprising" or "having" or the like specify the presence of the stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not preclude the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0034] Please refer to Figure 1 、 Figure 6 and Figure 7 As shown in

[0035] a wheel hub conveying system, comprising:

[0036] a conveyor, which includes a bracket 1, a gear 2 and a chain 3;

[0037] The bracket 1 includes an outer ring bracket 111 and an inner ring bracket 112. Support legs 113 are provided at the bottom ends of the outer ring bracket 111 and the inner ring bracket 112, and an opening 114 is provided between the outer ring bracket 111 and the inner ring bracket 112.

[0038] Based on the above, the setting of the opening 114 enables the pin between the chain 3 and the connecting frame 4 to move along the direction of the opening 114, and the outer ring bracket 111 and the inner ring bracket 112 cooperate with each other to protect and limit the chain 3. Figures 2 - 5

[0039] As shown in a connecting frame 4, which is connected to the chain 3 through a pin;

[0040] a transmission cylinder 5, which is connected to the connecting frame 4 through a bearing. The transmission cylinder 5 includes a cylinder body 51. A first limiting strip 52 is provided on the inner wall of the cylinder body 51, and a gear ring 6 is provided outside the cylinder body 51;

[0041] Based on the above, the connecting frame 4 is connected to the chain 3, thereby playing a role in driving the transmission cylinder 5 to move together. The setting of the transmission cylinder 5 enables the gear ring 6 to rotate on its own after meshing with the rack 144. While the main rod 7 can rotate together after the first limiting strip 52 and the limiting groove 72 cooperate with each other, the main rod 7 can move vertically along the direction of the transmission cylinder 5.

[0042] As Figures 3 - 5 and Figure 8 shown, a top block 8 is provided between the limiting ejector rod 9 and the main rod 7. The top block 8 includes a hollow block body 81. A placement groove 82 is provided on the upper surface of the hollow block body 81. A second limiting strip 83 is provided on the inner wall of the hollow block body 81. The second limiting strip 83 extends into the limiting groove 72. The hollow block body 81 is connected to the main rod 7 through the limiting ejector rod 9.

[0043] Based on the above, the limiting ejector rod 9 plays an effect of fixing the position of the hub, while the top block 8 plays a role in connecting the limiting ejector rod 9 and the main rod 7, making the installation of the limiting main rod 9 more stable.

[0044] As Figures 3 - 5 shown, the bottom block 10 includes an external thread block 101. The external thread block 101 is provided at the bottom end of the main rod 7 through a screw. A third limiting strip 102 is provided on the inner wall of the external thread block 101. The third limiting strip 102 extends into the limiting groove 72. A return spring 11 is provided between the transmission cylinder 5 and the external thread block 101.

[0045] The bottom end of the bottom block 10 is provided with a bottom cylinder 12 in a threaded manner. A ball 13 is provided between the bottom block 10 and the bottom cylinder 12. The ball 13 extends below the bottom cylinder 12.

[0046] Based on the above, after the bottom cylinder 12 is connected to the bottom block 10, the ball 13 is arranged between the two. The ball 13 makes the movement of this adaptive bracket smoother. And through the setting of the bottom block 10, the return spring 11 can be arranged between the bottom block 10 and the transmission cylinder 5. Then, when the main rod 7 moves upward, it squeezes the return spring 11, causing the return spring 11 to generate a reverse elastic force.

[0047] As Figure 1 and Figure 9 shown, the lifting platform 14 includes side plates 141. A trapezoidal block 142 is provided between the side plates 141. Both ends of the trapezoidal block 142 are inclined surfaces. The lifting platform 14 is fixed to the ground through screws. A stress block 143 is provided inside the trapezoidal block 142. A rack 144 is provided on the surface of the side plate 141. The rack 144 can mesh with the gear ring 6.

[0048] Based on the above, the lifting platform 14 and the conveyor are both arranged on the ground. When the adaptive bracket moves to the position of the lifting platform 14 driven by the chain 3, the adaptive bracket moves along the direction of the trapezoidal block 142. At this time, the main rod 7 drives the limit ejector rod 9 and the hub to move upward together. After the return spring 11 is compressed by force, it generates a downward elastic force. In this process, the hub is lifted to a height convenient for spraying paint. After the paint spraying is completed, the main rod 7 is reset under the action of the return spring 11, that is, the effect of lowering the center of gravity is achieved.

[0049] In actual use of this embodiment, the conveyor drives the adaptive bracket to move. During the movement process, that is, the process of driving the hub to be conveyed. During this process, the adaptive bracket is in direct contact with the ground and is in a state with a lower center of gravity. At this time, the hub and the adaptive bracket are not easy to shake because of the lower center of gravity.

[0050] When the adaptive bracket moves to the position of the lifting platform 14, the adaptive bracket moves along the direction of the trapezoidal block 142. At this time, the main rod 7 drives the limit ejector rod 9 and the hub to move upward together. After the return spring 11 is compressed by force, it generates a downward elastic force. In this process, the hub is lifted to a height convenient for spraying paint. After the paint spraying is completed, the main rod 7 is reset under the action of the return spring 11.

[0051] In the above process, the gear ring 6 and the rack 144 generate relative movement, so that the gear ring 6 drives the transmission cylinder 5, the main rod 7 and the hub to rotate, and thus the paint spraying is more uniform.

[0052] Compared with the traditional hub ground chain conveyor line, this conveying system enables the main rod 7 and the hub to move vertically. When it is not transported to the position of the lifting platform 14, the adaptive bracket is in direct contact with the ground and is in a low position state with a lower center of gravity, and it is not easy to shake. When the adaptive bracket moves to the position of the lifting platform 14, the hub and the main rod 7 move upward to a position convenient for painting to meet the requirements of painting.

[0053] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
