Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example

[0035] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a cam device for conveying wheel assemblies includes a base 1, a drive structure 2 mounted on the base, and a conveying and lifting structure 3 mounted on the base and connected to the drive structure. In this embodiment, the base is a rectangular plate-shaped base, and a bearing seat 4 is fixed to one end of the top surface of the base and a drive support seat 5 is fixed to the other end of the top surface. The bearing seat and the drive support seat can be fixed to the base by welding or screws, and their height can be processed and set as needed.

[0036] like Figure 2 and Figure 3 As shown, in this embodiment, the driving structure includes a drive motor 21, a cam 22, a drive cylinder 23, and a drive support rod 24. The drive support rod can be a straight rod or a combined rod structure, mainly used to synchronously drive both ends of the conveying and lifting structure to ensure the stability and consistency of both ends during lifting. During assembly, the drive motor is fixed to the side of the drive support seat, the cam is located inside the drive support seat and fixed to the main shaft of the drive motor, the drive cylinder is fixed to the top surface of the base, and the drive support rod is fixed to the piston shaft of the drive cylinder.

[0037] like Figure 2 , Figure 4 and Figure 5 As shown, the conveying and lifting structure includes a conveying frame 31, a linkage mechanism 32, a front crank arm structure 33, and a rear crank arm structure 34; the conveying frame is a conventional structure of the prior art, which is simply applied. The top surface of the conveying frame is provided with a feeding tray area, a tire loading tray area, and a conveying tray area from the front end to the rear end.

[0038] During assembly, the linkage mechanism is connected between the conveyor frame and the drive cam, and the front crank arm structure and the rear crank arm structure are respectively connected on both sides of the centerline of the conveying direction of the conveyor frame; the bottom ends of the front crank arm structure and the rear crank arm structure are connected to the drive support rod through the first shaft, and the middle part of the front crank arm structure is connected to the shaft support seat through the first pin, and the middle part of the rear crank arm structure is connected to the drive support seat through the second pin.

[0039] In use, the drive cylinder drives the drive rod to extend and retract, and the front and rear crank arm structures realize the lifting and lowering of the conveyor frame. The drive motor drives the cam to rotate, and the linkage mechanism realizes the repeated up and down trajectory movement of the conveyor frame.

[0040] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, a front guide rail 6 and a rear guide rail 7 are fixed to the bottom wall of the conveyor frame, located on either side of the centerline of the conveying direction. Furthermore, sliders 8 are fixed to the top of both the front and rear crank arm structures. The slider of the front crank arm structure is slidably mounted on the front guide rail, and the slider of the rear crank arm structure is slidably mounted on the rear guide rail. This design not only ensures the stability of the connection but also guarantees the effectiveness of the conveyor frame's translation relative to the front and rear crank arm structures.

[0041] like Figure 4 and Figure 5 As shown, in this embodiment, the front crank arm structure includes a vertical support rod 331 and an L-shaped support rod 332. During assembly, the slider is fixed to the top of the vertical support rod, and the first pin is connected to the corner of the L-shaped support rod. The top of the L-shaped support rod is connected to the vertical support rod, and the bottom is connected to the first shaft. That is, the L-shaped support rod can rotate around the first pin, thereby realizing the lifting and lowering action of the vertical support rod. Furthermore, in this embodiment, the vertical support rod is provided with several adjustment holes 333, and the top of the L-shaped support rod is set in one of the adjustment holes through the first connecting shaft. The assembly position can be adjusted as needed to meet the usage requirements of different situations.

[0042] In practical applications, the rear crank arm structure is identical to the front crank arm structure, and the L-shaped support rods of both structures bend in the same direction. Because the L-shaped support rods of both structures bend in the same direction, the consistency of lifting and lowering of the front and rear ends of the conveyor frame can be ensured.

[0043] like Figure 4 and Figure 5 As shown, the linkage mechanism includes an upper linkage 321, a lower linkage 322, and a control linkage 323. During assembly, the top end of the upper linkage is rotatably connected to the front bottom surface of the conveyor frame via a second connecting shaft. The top end of the lower linkage is fixedly connected to the upper linkage via a connecting rod, and the bottom end of the lower linkage is rotatably connected to the front end of the drive support via a circular shaft. One end of the control linkage is connected to the convex edge of the cam via a third shaft, and the other end is rotatably connected to the middle of the lower linkage via a fourth shaft.

[0044] In use, the control link, under the action of the cam, causes the bottom end of the lower link to rotate around the circular shaft, which in turn drives the upper link to move up or down, causing the conveyor frame to move in a reciprocating motion.

[0045] Furthermore, in practical applications, the upper connecting rod is provided with several adjusting holes 324, and the connecting rod at the top of the lower connecting rod is connected to one of the adjusting holes. Adjustment can be performed as needed.

[0046] like Figure 1 As shown, in this embodiment, two tire loading worktables 10 are fixed on the base by support columns 9; the conveyor frame is located between the two tire loading worktables, and the tire loading tray area of ​​the conveyor frame is located in the middle of the tire loading worktables. The tire loading worktables facilitate tire loading operations.

[0047] Compared with the prior art, the present invention has the following positive effects: The drive structure of the present invention includes a drive motor, a cam, a drive cylinder and a drive support rod, and the conveying and lifting structure includes a conveying frame, a linkage mechanism, a front crank arm structure and a rear crank arm structure. The cam and linkage mechanism can realize the precise intermittent movement of the conveying frame in a specific range, improving the response speed and motion accuracy. The drive cylinder, in conjunction with the front crank arm structure and the rear crank arm structure, can realize the lifting of the conveying frame, improving the stability and reliability of use. The overall structure is compact and rigid, which can meet the usage requirements of different environments.

[0048] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0049] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, these obvious variations or modifications derived from the essential spirit of the present invention still fall within the scope of protection of the present invention.
