[0002] Track shoes are an important part of the running mechanism of special armored vehicles. Their processing quality and efficiency directly affect the vehicle's driving performance and the life of the entire track. In the processing of track shoes, the flipping mechanism plays a vital role. It can realize the effective flipping of the track shoes for multi-faceted processing and treatment.

[0003] In traditional track plate processing methods, the flipping operation often relies on manual or simple mechanical devices, which are not only inefficient but also have safety hazards. With the continuous development of mechanical automation technology, people's demand for flipping mechanisms for track plate processing is also increasing, requiring the flipping mechanism to achieve automated, efficient and safe flipping operations.

In order to smoothly carry out the next processing step, it is also necessary to use a position calibration mechanism to adjust and reset the track plate workpiece, which undoubtedly increases the workload of flipping the track plate and affects the processing quality and efficiency.

[0027] 4. By utilizing the cooperation of the driving screw and the nut plate, as well as the supporting function of the guide rod, the horizontal relative movement between the two sets of vertical mounting seats is realized, so that the spacing can be adjusted appropriately according to the track shoe workpieces of different widths, thereby enhancing the versatility and adaptability of the equipment; and by using the electric push cylinder, the driven rack, the spur gear and the active gear plate in coordination, the unidirectional driving force is converted into the synchronous relative movement of the upper moving seat and the lower moving seat, thereby realizing the adaptive adjustment of the height of the track shoe workpiece and meeting the processing requirements of workpieces of different sizes.

[0044] like Figure 4-Figure 6 As shown, a vertical mounting seat 11 is provided on one side of the two sets of assembly plates 7 close to each other, and a nut plate 10 is fixedly connected to the upper and lower ends of each set of vertical mounting seats 11, and an internal screw hole is penetrated through the middle of the nut plate 10, and a driving screw 9 is inserted into the internal screw hole. The driving screw 9 is limitedly rotated and installed on the assembly plate 7 and driven to rotate by a No. 1 motor. The thread directions of the two adjacent sets of driving screws 9 are opposite. Under the rotational action of the internal and external threads, the nut plate 10 drives the two sets of vertical mounting seats 11 to move horizontally toward each other, so that the two sets of vertical mounting seats 11 can be appropriately adjusted according to the track plate workpieces of different widths.

The pushing assembly includes a driven rack 14, a spur gear 15, an active toothed plate 16 and an electric push cylinder 17, and the electric push cylinder 17 is arranged on the vertical mounting seat 11, and the driven rack 14 and the active toothed plate 16 are both limitedly slidably mounted in the vertical mounting seat 11, and both sides of the active toothed plate 16 are meshed and connected with a group of spur gears 15, and the spur gears 15 are symmetrically arranged In the vertical mounting seat 11, the side of the spur gear 15 away from the active toothed plate 16 is meshed and connected to the driven rack 14, the end of the driven rack 14 away from the spur gear 15 is fixedly connected to the upper moving seat 12, and the end of the active toothed plate 16 away from the spur gear 15 is fixedly connected to the lower moving seat 13; by arranging the driven rack 14, the spur gear 15 and the active toothed plate 16 for use together, the unidirectional driving force of the electric push cylinder 17 can be converted into the synchronous opposite movement of the upper moving seat 12 and the lower moving seat 13, so as to achieve the purpose of adjusting the distance between the upper moving seat 12 and the lower moving seat 13, so as to be suitable for track plate workpieces of different heights.

[0047] like Figure 8 , Fig.10 as well as Fig.13 As shown, at least two groups of lateral positioning components 18 are arranged between the upper moving seat 12 and the lower moving seat 13. The upper and lower ends of the lateral positioning components 18 are connected to the upper moving seat 12 and the lower moving seat 13 through elastic limit clamps. The sides of the upper moving seat 12 and the lower moving seat 13 close to each other are provided with rectangular slots for accommodating the elastic limit clamps. The elastic limit clamps include a limit rod 31, a second spring 32 and a limit block 33. The limit rod 31 is horizontally placed in the rectangular slot, and the second spring 32 and the limit block 33 are movably sleeved on the limit rod 31; the end of the limit block 33 away from the limit rod 31 is fixedly connected to the lateral positioning component 18. The lateral positioning component 18 is composed of a plurality of connecting blocks assembled together, and two adjacent groups of connecting blocks are limitedly connected by dovetail blocks and slots;

[0048] Furthermore, by setting the limit rod 31, the second spring 32 and the limit block 33, the lateral positioning assembly 18 can move horizontally under the action of external force, and can play a role in lateral centering and tightening the track plate workpiece; and because the lateral positioning assembly 18 is composed of a plurality of connecting blocks assembled together, it can be adaptively telescopically adjusted as the positions of the upper moving seat 12 and the lower moving seat 13 change, thereby being suitable for the processing requirements of workpieces of different sizes.

[0049] like Figure 5 as well as Figure 6 As shown, a plurality of groups of synchronous and co-rotating conveying rollers 19 are provided on the side where the upper moving seat 12 and the lower moving seat 13 are close to each other, and are used to convey the crawler plate workpiece on the first conveying rail 2 to the second conveying rail 3; the plurality of groups of conveying rollers 19 are distributed linearly, and a group of pulleys are fixedly sleeved on the end of each group of conveying rollers 19, and the outsides of two adjacent groups of pulleys are connected in series by a group of belts, and the plurality of groups of pulleys are driven by the same group of conveying motors; by arranging conveying rollers 19 at the upper and lower ends of the upper moving seat 12 and the lower moving seat 13, the workpiece can be pushed before and after flipping.

[0050] like Fig.11 as well as Fig.12 As shown, the upper moving seat 12 and the lower moving seat 13 are also provided with a longitudinal positioning assembly, which includes a connecting plate 21, a driven plate 22 and a longitudinal pressing block 20. A group of longitudinal pressing blocks 20 are provided between two adjacent groups of conveying rollers 19. One end of the plurality of longitudinal pressing blocks 20 away from the conveying rollers 19 is fixedly connected to the connecting plate 21. One end of the connecting plate 21 away from the longitudinal pressing block 20 is fixedly connected to the driven plate 22. At least two groups of oblique grooves 23 are provided through the driven plate 22. A cylindrical plug rod 24 is inserted into each group of oblique grooves 23. The cylindrical plug rod 24 is fixedly connected to the transverse push plate 25. One end of the transverse push plate 25 is fixedly connected to the horizontal push plate 25. The first spring 26 of no less than four groups is fixedly connected, the other end of the horizontal push plate 25 extends into the vertical mounting seat 11 and contacts the main push plate 27, the active plate is limitedly slidably installed in the vertical mounting seat 11, and a matching screw hole is opened in the middle of the active plate, a threaded rod 28 is inserted in the matching screw hole, and the threaded rod 28 is horizontally placed on the vertical mounting seat 11 and driven to rotate by the second motor 29; the side wall of the main push plate 27 is also fixedly connected to the door-type push frame 30, and the end of the door-type push frame 30 away from the main push plate 27 contacts the lateral positioning assembly 18, and the door-type push frame 30 pushes the lateral positioning assembly 18 to move horizontally under the push of the main push plate 27;

[0051] Furthermore, the threaded rod 28 is driven to rotate by the No. 2 motor 29. Under the screwing action of the internal and external threads, the main push plate 27 is subjected to force to simultaneously push the lateral push plate 25 and the door-type push frame 30 to move horizontally synchronously. Under the cooperation of the driven plate 22, the oblique groove 23 and the cylindrical plug rod 24, the connecting plate 21 is subjected to force to drive the multiple groups of longitudinal pressure blocks 20 to move up and down. The multiple groups of longitudinal pressure blocks 20 align and press the workpiece toward the center and protrude from the surface of the conveying roller 19, so that the workpiece can be flipped stably.

[0052] When the present invention is in use: first, the first conveyor rail 2 conveys the track plate workpiece to be assembled to the rotating frame body. When the workpiece is completely located between the upper moving seat 12 and the lower moving seat 13, the second motor 29 is turned on to drive the main push plate 27 to rotate clockwise. Under the screwing action of the internal and external threads, the main push plate 27 is subjected to force and simultaneously pushes the lateral push plate 25 and the door-type push frame 30 to move horizontally synchronously. The door-type push frame 30 drives the lateral positioning assembly 18 to move toward the direction of the conveying roller 19 under the push of the main push plate 27, thereby aligning and pressing the workpiece front and back; at the same time, the lateral push plate 25 squeezes the first spring 26 and drives it The cylindrical plug rod 24 on the upper part moves toward the direction of the workpiece, and the cylindrical plug rod 24 acts on the oblique groove 23, so that the driven plate 22 is forced to drive the connecting plate 21 to move toward the direction of the conveying roller 19, and multiple groups of longitudinal pressing blocks 20 align the workpiece in the middle and press it and protrude from the surface of the conveying roller 19. At this time, the front, back, top and bottom directions of the workpiece are all pressed and fixed. Then, by turning on the rotating motor 6, the rotating shaft 5 drives the two groups of assembly plates 7 to rotate together. The two groups of assembly plates 7 are connected by the guide rod 8, so that the vertical mounting seat 11 will also rotate with the assembly plate 7, so that the workpiece can stably perform a 180° flip action;

[0053] When the flipping is completed, the second motor 29 is turned on again to drive the main push plate 27 to rotate counterclockwise. Under the screwing action of the internal and external threads, the main push plate 27 is forced to pull the door-type push frame 30 to move horizontally and release the squeezing force on the lateral push plate 25, so that the lateral push plate 25 is restored to its original position under the action of the first spring 26, and the door-type push frame 30 also releases the squeezing force on the lateral positioning assembly 18. The lateral positioning assembly 18 also moves in the direction away from the conveying roller 19 under the elastic force of the second spring 32, thereby releasing the workpiece in the front and rear directions; at the same time, the cylindrical plug rod 24 on the lateral push plate 25 acts on the oblique groove 23 again, so that the driven plate 22 is forced to drive the connecting plate 21 to move in the direction away from the conveying roller 19, and the multiple groups of longitudinal pressing blocks 20 release the clamping effect on the workpiece, so that the workpiece falls normally on the surface of the conveying roller 19 and is conveyed to the second conveying rail 3 by the multiple groups of conveying rollers 19.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
