DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the technical solution more clear, the technical solution is further described in detail below in conjunction with specific implementation methods. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the technical solution.

[0031] In order to solve the problem that the turning work on the wheel hub loading and unloading conveyor line in the prior art is done manually, the labor intensity is high and the production efficiency is low, such as Figure 1-Figure 4 As shown, this embodiment provides a welding turning device for automobile wheel hub 34, such as Figure 1 As shown, the flipping device includes a base frame 1, a flipping drive mechanism 2, a flipping frame 3, a sprocket drive device 4, a pressing device 5 and other components.

[0032] Specifically, the base frame 1 in this embodiment is a frame-type structure, which serves as the installation base for the flip drive mechanism 2, the flip frame 3, the sprocket drive device 4 and the clamping device 5. The top of the base is provided with two bearing seats 12 on the left and right sides, and the flip frame 3 is installed in the area between the two bearing seats 12. Figure 1In the position shown, a drive shaft 10 is installed on the left and right sides of the flip frame 3 respectively. The drive shaft 10 is rotatably installed in the bearing seat 12 through a bearing 11. The end of the drive shaft 10 extends away from the flip frame 3 to the outside of the bearing seat 12 and a cylindrical gear 8 is installed at its end. The flip frame 3 can be hingedly rotated with the base frame 1 through the cooperation of the bearing 11 and the bearing seat 12.

[0033] Linear slide rails are arranged below the flip frame 3 on both sides of the base corresponding to the bottom. The top surface of the linear slide rail is a guide part. A driving cylinder 14 is arranged on one side of the bearing seat 12. The protruding end of the driving cylinder 14 is connected to the end of the rack 9 through a floating joint 15. The rack 9 is installed on the sliding part of the linear slide rail 13. The rack 9 is meshed with the above-mentioned cylindrical gear 8. Therefore, when the driving cylinder 14 drives its action end to move forward and backward, the flip frame 3 can be driven to flip as a whole through the cooperation of the rack 9 and the cylindrical gear 8.

[0034] In this embodiment, the flipping driving mechanism 2 is disposed on both the left and right sides of the flipping frame 3 , and the effect of driving the flipping frame 3 to flip can be achieved by synchronously controlling the extension and retraction of the extended end of the driving cylinder 14 .

[0035] In addition, the bottom frame 1 is symmetrically provided with a positive limit buffer 6 and a negative limit buffer 7 for limiting the flip angle and buffering the end of the stroke of the flip frame 3. The positive limit buffer 6 and the negative limit buffer 7 act on the flip frame 3 to buffer and limit when flipping 180° in the positive direction and 180° in the reverse direction, respectively.

[0036] The front of the flip frame 3 is provided with an opening, and a blocking component for positioning the automobile wheel hub 34 is provided at a position corresponding to the front opening in the flip frame 3; in this embodiment, the blocking component is two vertical blocking rods, and the interval between the two blocking rods is smaller than the diameter of the automobile wheel hub 34. In this embodiment, the advantage of using the blocking rods is that the automobile wheel hubs 34 of different sizes and specifications can be adapted and fixed by adjusting the interval between the blocking rods.

[0037] like Figure 2As shown, the clamping device 5 in this embodiment includes a clamping cylinder 27, a guide rod 31, a linear bearing 32 and a pressure strip 33. The tail of the clamping cylinder 27 is fixedly mounted on the flip frame 3, the extended end of the clamping cylinder 27 is back-to-back clamping position, the extended end of the clamping cylinder 27 is connected to the first end of the guide rod 31, the second end of the guide rod 31 is connected to the pressure strip 33, and the guide rod 31 passes through the gap of the conveying roller group. Specifically, the clamping cylinder 27 and the four linear bearings 32 are fixed above the flip frame 3, the pressure rod 28 is connected to the output rod end of the clamping cylinder 27, the pressure rod 28 and the pressure plate 30 are fixedly connected through two transition rods 29, the pressure plate 30 is fixedly connected to one end of the four guide rods 31, the four guide rods 31 pass through the four linear bearings 32, the other end of the four guide rods 31 is fixedly connected to the two pressure strips 33, and the two pressure strips 33 are pressed on the upper end of the automobile wheel hub 34. In this embodiment, the pressing cylinder 27 is inverted. The inverted pressing cylinder 27 can provide a larger stroke to avoid interference between the action of the pressing cylinder 27 and the flip frame 3.

[0038] like Figure 3 As shown, the flip frame 3 includes a left frame and a right frame, and two rows of conveying rollers are arranged between the left frame and the right frame. A double-row sprocket is arranged at one end of the conveying roller group, and adjacent conveying rollers are connected by a short chain 21, and the upper and lower rows of conveying rollers are connected by a long chain 22. In this embodiment, the conveying roller group includes a plurality of single conveying rollers, and the ends of the single conveying rollers of each conveying roller group are equipped with double-row sprockets, and the adjacent single conveying rollers are connected to the double-row sprockets through a plurality of short chains 21. The sprocket drive device 4 also includes a long chain 22, which is wound around two single conveying rollers belonging to different conveying roller groups, so that the two conveying roller groups are connected in power. The conveying roller drive mechanism includes a variable frequency motor 23 and a drive chain 25. The variable frequency motor 23 is installed below the flip frame 3 through a motor seat 26, and a drive sprocket 24 is installed at the rotating end of the variable frequency motor 23. The drive sprocket 24 and the conveying roller are connected in power through the drive chain 25.

[0039] When the flipping device is used, first keep the pressing device 5 in the extended state, and the position of the flip frame 3 and the position of the pressing cylinder 27 are as follows: Figure 1 As shown, the transport vehicle wheel hub 34 enters the conveying roller group position, and the frequency conversion motor 23 in the sprocket drive device 4 is started. The frequency conversion motor 23 drives the double-row sprocket, the short chain 21 and the long chain 22 to move synchronously by driving the sprocket 24 and the driving chain 25, so that all the single conveying rollers of the conveying roller group move, and the vehicle wheel hub 34 is transported by the lower conveying roller group into the flip frame 3, and the vehicle wheel hub 34 moves until it is blocked by the baffle rod, that is, the vehicle wheel hub 34 is confined between the two baffle rods, that is, the positioning and the centering are completed.

[0040] At this time, the pressing cylinder 27 is retracted, and the action end of the pressing cylinder 27 drives the pressing rod 28, the guide rod 31 and the pressing strip 33 to be pressed down synchronously, so that the pressing strip 33 is pressed on the automobile wheel hub 34.

[0041] Then, the driving cylinder 14 is driven, and its extended end drives the rack 9 to move through the floating joint 15. The rack 9 is guided to move linearly through the linear slide rail. The rack 9 drives the entire flip frame 3 and the automobile wheel hub 34 inside the flip frame 3 to flip over through the cooperation with the cylindrical gear 8. In this process, the flip frame 3 is rotated 180° in the positive direction and reaches the positive limit position. At the same time, the clamping device 5 is flipped from the original upper position to the lower position. At this time, the clamping cylinder 27 in the clamping device 5 is driven to extend, and the automobile wheel hub 34 can fall onto the conveying roller group. Then, the automobile wheel hub 34 is driven to exit the flip frame 3 through the sprocket drive device 4.

[0042] Finally, the flip drive mechanism 2 drives the flip frame 3 to flip 180° in the opposite direction and reach the negative limit position, returning to the Figure 1 The wheel hub is in the position shown, waiting for the next wheel hub to enter the turning frame 3 for turning over.

[0043] This turning equipment has the characteristics of high degree of automation, can be integrated and installed on the wheel loading and unloading conveyor line, and can be widely used for turning over wheels of various specifications.

[0044] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
