Description

Technical Field

[0001] This application relates to the technical field of wheel spoke processing, specifically to a wheel spoke processing device for engineering vehicles. Background Art

[0002] The wheel spoke is an important structure on the wheel. According to different structures, it can be divided into a spoke-type wheel spoke and a spoke-type wheel spoke. The spoke-type wheel spoke is jointly composed of a spoke plate, a rim and a valve nozzle outlet. The spoke plate is usually made of steel and connects the hub and the rim. Due to its large load-bearing capacity, spoke-type wheel spokes are generally used in engineering vehicles.

[0003] After the spoke plate is stretched and formed from a circular blank, it also needs to go through processing processes such as punching and trimming. Since different processing stations have different positioning jigs, manual operations of multiple disassembly, handling and re-clamping are required during this period to transfer the spoke plate to the next processing station, wasting a lot of manpower and transfer time, with low overall efficiency, resulting in low order digestion capacity and affecting the production capacity of the factory.

[0004] Therefore, this application provides a wheel spoke processing device for engineering vehicles to solve the above problems. Summary of the Utility Model

[0005] This application provides a wheel spoke processing device for engineering vehicles, aiming to solve the problem that the existing spoke plate processing device requires a large amount of human resources and time costs to cooperate with production due to different positioning jigs, resulting in low efficiency and low production capacity as mentioned in the background art.

[0006] To achieve the above purpose, this application provides the following technical solution: A wheel spoke processing device for engineering vehicles, including a production line track and a track seat installed on the production line track and moving along the production line track.

[0008] The positioning mechanism includes U-shaped chucks that are symmetrically arranged and rotatably connected to the side of the two support frames facing each other, a lifting plate that longitudinally moves inside the U-shaped chuck for pressing the wheel spoke, a second driving component installed on the U-shaped chuck for driving the lifting plate to lift and lower, side roller wheels that are arranged side by side and rotatably inside the U-shaped chuck for contacting the side of the wheel spoke, and a flipping motor that is fixedly installed on the side of the support frame facing away from each other and whose output ends are respectively connected to the corresponding U-shaped chucks. Among them, a plurality of roller wheels that are rotationally installed on the bottom surface of the inner side of the U-shaped chuck and the bottom surface of the lifting plate and are distributed in a fan-shaped array for supporting and positioning the rotation of the wheel spoke between the two U-shaped chucks are provided.

[0009] A rotating motor with an output end connected to one of the side roller wheels is fixedly installed on one of the U-shaped chucks for driving the spoke to rotate through the side roller wheel. In this way, by setting a positioning mechanism on the track seat of the assembly line, the assembly line operation and automatic clamping and positioning of spoke processing are realized, reducing the time for manual disassembly, handling and clamping, significantly improving the processing efficiency of the spoke, and reducing costs and increasing efficiency.

[0010] Preferably, one end of the U-shaped chuck away from the rotating motor is provided with a transmission component for synchronously rotating the two side roller wheels.

Specific implementation manners

[0025] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0026] Embodiment 1

[0027] This embodiment provides a wheel spoke processing device for engineering vehicles, as Figures 1-3 shown. This wheel spoke processing device for engineering vehicles includes an assembly line track 1 and a track seat 2 installed on the assembly line track 1 and moving along the assembly line track 1.

[0028] A support frame 3 that slides and moves closer to or away from each other is slidably connected to the track seat 2. A positioning mechanism 5 for clamping both sides of the wheel spoke is arranged on the two support frames 3. A first drive assembly 4 for driving the two support frames 3 to move is arranged on the track seat 2.

[0029] The positioning mechanism 5 includes U-shaped chucks 51 that are symmetrically arranged and rotatably connected to the mutually approaching sides of the two support frames 3, a lifting plate 52 that longitudinally moves inside the U-shaped chucks 51 and is used to press the wheel spokes, a second driving assembly 53 installed on the U-shaped chucks 51 and used to drive the lifting plate 52 to move up and down, side roller wheels 57 that are arranged side by side and rotatably inside the U-shaped chucks 51 and are used to contact the side surfaces of the wheel spokes, and a flipping motor 56 that is fixedly installed on the mutually remote sides of the support frames 3 and whose output ends are respectively connected to the corresponding U-shaped chucks 51. Among them, several roller wheels 54 that are rotatably installed on the bottom surfaces of the inner sides of the U-shaped chucks 51 and the bottom surface of the lifting plate 52 and are distributed in a fan-shaped array are used to support and position the rotation of the wheel spokes between the two U-shaped chucks 51.

[0030] A rotating motor 58 whose output end is connected to one of the side roller wheels 57 is fixedly installed on one of the U-shaped chucks 51 and is used to drive the wheel spokes to rotate through the side roller wheel 57.

[0031] During use, in the initial state: The two support frames 3 maintain a certain initial distance through the first driving assembly 4, the two U-shaped chucks 51 are in an open state, the lifting plate 52 is in a high position, and the side roller wheels 57 and the roller wheels 54 are all in a freely rotating state.

[0032] When clamping the wheel spokes: When the wheel spokes are fed between the two support frames 3, the first driving assembly 4 is started to drive the two support frames 3 to approach each other until the openings of the two U-shaped chucks 51 completely surround both sides of the wheel spokes. At the same time, the second driving assembly 53 is started to drive the lifting plate 52 to descend until the bottom surface of the lifting plate 52 contacts and presses the top surface of the wheel spokes, realizing the up-and-down clamping of the wheel spokes.

[0033] When the wheel spokes need to be horizontally rotated: The roller wheels 54 provide support for the wheel spokes up and down and allow the wheel spokes to freely rotate in the horizontal direction. At this time, the rotating motor 58 is started, and through one of the side roller wheels 57 contacting the side surface of the wheel spokes, the wheel spokes are driven to rotate in order to perform machining operations in the circumferential direction. It is also possible to rotate the wheel spokes to expose the wheel spoke area blocked by the U-shaped chucks 51, which is convenient for comprehensive machining.

[0034] When the wheel spokes need to be flipped: The flipping motor 56 is started, and the entire wheel spokes are driven to be flipped and adjusted through the U-shaped chucks 51 to adapt to different processing requirements, such as punching, trimming, etc.

[0035] Processing operations: When the wheel spokes are accurately positioned and clamped, the pipeline track 1 may pause moving or move to a specific processing station. At this station, according to the processing requirements, processing operations such as punching, trimming, and grinding may be performed, and these operations may be completed by automated equipment integrated with the pipeline or manual operations.

[0036] Release and transfer: The assembly line track 1 continues to run, and the track base 2 moves the support frame 3 and the positioning mechanism 5 to the next position to prepare for receiving the next spoke or performing other operations (such as cleaning, maintenance, etc.); after processing is completed, the second drive assembly 53 drives the lifting plate 52 to rise, releasing the clamping of the spoke. The first drive assembly 4 drives the two support frames 3 to move away from each other, opening the C-shaped chuck 51 and releasing the spoke.

[0037] Cyclic operation: The above steps are continuously repeated to achieve continuous processing of the spokes, improving production efficiency and capacity.

[0038] Furthermore, one end of the C-shaped chuck 51 away from the rotating motor 58 is provided with a transmission assembly 59 for synchronously rotating the two side roller wheels 57. The transmission assembly 59 includes a driving wheel 591 and a secondary wheel 592 that are rotatably mounted on the C-shaped chuck 51 and are respectively connected to the rotating shafts of the two side roller wheels 57, and a transmission belt 593 sleeved outside the driving wheel 591 and the secondary wheel 592 for synchronously rotating the driving wheel 591 and the secondary wheel 592; when the rotating motor 58 is started and drives the connected side roller wheel 57 to rotate, the rotation of this side roller wheel 57 is transmitted to the driving wheel 591 through the rotating shaft, and the rotation of the driving wheel 591 is further transmitted to the secondary wheel 592 through the transmission belt 593. Due to the synchronous transmission effect of the transmission belt, the secondary wheel 592 also rotates at the same speed and in the same direction. Finally, the rotation of the secondary wheel 592 is transmitted to the other side roller wheel 57 through its rotating shaft, realizing the synchronous rotation of the two side roller wheels 57.

[0039] Specifically, the first drive assembly 4 includes a bidirectional lead screw 41 rotatably mounted on the track base 2 and threadedly connected to the two support frames 3 at both ends, and a clamping motor 42 fixedly mounted on the track base 2 with its output end connected to the bidirectional lead screw 41; when the clamping motor 42 is started, it drives the bidirectional lead screw 41 to rotate. Since the two ends of the bidirectional lead screw 41 are respectively threadedly connected to the two support frames 3, the rotation of the lead screw is converted into a linear motion of the support frame 3. When the rotation direction of the lead screw changes, the two support frames 3 move relatively closer or farther away, thereby changing the distance between the C-shaped chucks 51 and realizing the clamping or release of the spoke.

[0040] Specifically, the second drive assembly 53 includes a gantry 531 fixedly connected to the top of the lifting plate 52 and slidably connected to the C-shaped chuck 51, and a first electric telescopic rod 532 fixedly mounted on the C-shaped chuck 51 with its movable end connected to the gantry 531; when the first electric telescopic rod 532 is started, it extends or retracts its movable end, thereby pushing or pulling the gantry 531 to move up and down. Since the gantry 531 is fixedly connected to the top of the lifting plate 52, the up and down movement of the gantry 531 drives the lifting plate 52 to move synchronously, thereby realizing the pressing or release of the spoke.

[0041] It should be noted that the surfaces of the side roller 57 and the roller 54 are both rubber surfaces; the rubber surface material has good friction and wear resistance, which can ensure sufficient driving force and stability when driving the wheel spoke to rotate. At the same time, the rubber surface material can also reduce the wear and noise between the wheel spoke and the roller to a certain extent, improving the smoothness and comfort of the processing process.

[0042] Embodiment 2

[0043] Different from Embodiment 1, when the torque of the processing head is large, there will be a problem of wheel spoke offset when relying solely on the friction of the side roller 57 to position the wheel spoke, resulting in a reduction in the quality of the finished product. Therefore, pressing pads 551 for pressing the surface of the wheel spoke and moving closer to or away from each other symmetrically are arranged between the bottom of the lifting plate 52 and the U-shaped chuck 51, and the lifting plate 52 and the U-shaped chuck 51 are both provided with second electric telescopic rods 55 with movable ends connected to the pressing pads 551.

[0044] When further locking is required after the wheel spoke is positioned, start the second electric telescopic rod 55 to drive the pressing pad 551 to move closer to the upper and lower surfaces of the wheel spoke until it abuts against the wheel spoke and clamps it. Since the pressing pads 551 are symmetrically arranged, they can evenly press both sides of the wheel spoke to prevent it from shifting during the processing; after the processing is completed, start the second electric telescopic rod 55 to retract the movable end, separate the pressing pad 551 from the surface of the wheel spoke, and release the pressing force. Subsequently, loosen the wheel spoke according to the steps in Embodiment 1 and perform subsequent adjustment or transfer.

[0045] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and its concept of the present application, makes equivalent replacements or changes, and should be covered by the protection scope of the present application.
