Description

Technical Field

[0001] The present invention relates to the technical field of wheel hub processing, and in particular to a new energy vehicle wheel hub processing device and a processing method thereof. Background Art

[0002] New energy vehicles are driven by clean energy, such as electric vehicles or hybrid vehicles, to reduce exhaust emissions and energy consumption, thereby promoting environmental protection and sustainable travel. The hub is a part of the wheel that supports the vehicle, bears the weight of the vehicle and transmits power. It also plays an important role in the aesthetics and performance of the vehicle.

[0003] Wheel hubs are generally produced by casting processes. In order to make the wheel hubs meet the specification requirements during the production process, turning and drilling operations are performed when necessary. The mounting holes distributed in a circular array need to be drilled multiple times. The same equipment needs to repeatedly drill the same wheel hub multiple times, which is cumbersome and leads to low drilling efficiency. Therefore, those skilled in the art provide a new energy vehicle wheel hub processing device and a processing method thereof to solve the problems raised in the above background technology. Summary of the invention

[0004] The purpose of the present invention is to address the problems existing in the background technology and to propose a new energy vehicle wheel hub processing device and a processing method thereof.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a new energy vehicle wheel hub processing device and a processing method thereof, comprising a processing table, a base, a mounting box, a drilling motor, a fixing motor, a drill rod and an adjusting disk, wherein a processing table is arranged above the base, a mounting frame is arranged at the upper end of the processing table, a hydraulic rod 1 is arranged inside the mounting frame, a mounting box is arranged at the telescopic end of the hydraulic rod 1, a ring seat is arranged inside the mounting box, a drilling motor is arranged inside the ring seat above the ring seat, a rotating shaft is arranged at the output end of the drilling motor, a multi-stage pitch-adjusting gear is sleeved on the outer wall of the rotating shaft, an adjusting disk is arranged inside the mounting frame, adjusting grooves distributed in a ring array are opened inside the adjusting disk, a travel rod is arranged inside the adjusting groove, a bearing seat is arranged at the lower end of the travel rod, a drill rod is rotatably installed at the lower end of the bearing seat, and a driven gear meshing with the multi-stage pitch-adjusting gear is sleeved on the outer wall of the drill rod.

[0006] Preferably, the upper end of the adjustment disk is provided with connecting rods distributed in an annular array and penetrating the upper end of the ring seat, the outer walls of the connecting rods are sleeved with gear rings, an adjustment motor is fixed above the ring seat, and an adjustment gear meshing with the gear ring is provided at the output end of the adjustment motor. The connecting rods are used to fix the gear ring so that the gear ring is fixed inside the ring seat and supported for rotation.

[0007] Preferably, a top ball is rotatably mounted inside the upper end of the travel rod, and the upper end of the top ball rolls against the inner wall of the upper end of the ring seat. The top ball fits against the inner wall of the upper end of the ring seat, and the upper end of the travel rod is rolled to support the upper end of the travel rod, thereby preventing the travel rod from moving upward.

[0008] Preferably, the outer wall of the drill rod is sleeved with a collar, and the lower end of the collar is rotatably mounted with bottom balls distributed in an annular array and rollingly fitted with the inner wall of the lower end of the ring seat. The bottom balls roll and fit with the inner wall of the lower end of the ring seat to limit the lower end of the travel rod and prevent the travel rod from moving downward.

[0009] Preferably, the upper end of the ring seat is provided with symmetrically distributed hydraulic rods 2, the outer wall of the drilling motor is sleeved with a machine sleeve, and the telescopic end of the upper end of the hydraulic rod 2 is connected to the machine sleeve. The driving force of the hydraulic rod 2 acts on the drilling motor through the machine sleeve.

[0010] Preferably, a fixed motor is provided at the upper end of the base, a screw rod 1 with relatively distributed outer wall threads is provided at the output end of the fixed motor, and a travel plate is installed on the outer wall threads of the screw rod 1.

[0011] Preferably, a screw rod 2 with outer wall threads arranged opposite to each other is arranged below the screw rod 1, a bevel gear 2 is sleeved on the outer wall of the screw rod 2, and a bevel gear 1 meshing with the bevel gear 2 is sleeved on the outer wall of the screw rod 1. When the screw rod 1 rotates, the bevel gear 2 is pushed to rotate by the bevel gear 1, thereby driving the screw rod 2 to rotate.

[0012] Preferably, a plurality of bearing brackets are provided at the upper end of the base, and the screw rod 1 and the screw rod 2 are both rotatably mounted inside the bearing brackets. The bearing brackets rotatably support the screw rod 1 and the screw rod 2, so that the screw rod 1 and the screw rod 2 can stably rotate above the base.

[0013] Preferably, the upper end of the base is provided with a cross-distributed guide rail, the lower end of the travel plate is slidably sleeved on the outer wall of the guide rail, the upper end of the processing table is provided with a travel groove, and the travel plate is slidably installed inside the travel groove. The travel plate is slidably guided by the guide rail, moves inside the processing table through the travel groove, and provides multi-point support for the wheel hub.

[0014] A new energy vehicle wheel hub processing method, the wheel hub processing method steps are as follows: S1: It is worth noting that the multi-stage pitch gear is composed of a disc gear distributed longitudinally and whose radius decreases from top to bottom. The multi-stage pitch gear is meshed with the driven gear. Under the driving force of the drilling motor, the multi-stage pitch gear and the driven gear are driven to rotate through the rotating shaft, thereby driving the drill rod to rotate. At the same time, the hydraulic rod drives the installation box to move longitudinally, thereby driving the drill rod to descend, and drilling the wheel hub at four points at the same time; S2: When the model of the wheel hub changes, the position of the mounting hole will also change. At this time, the adjusting motor drives the adjusting gear to rotate and push the gear ring. The rotational force of the gear ring acts on the adjusting disk through the connecting rod. During the rotation of the adjusting disk, the internal adjusting groove squeezes the stroke rod, and the position of the stroke rod changes. At the same time, the adjusting rod rolls and fits with the ring seat through the top ball and the bottom ball. Then, when the adjusting groove squeezes the stroke rod to adjust the position, the horizontal height of the adjusting rod remains unchanged, ensuring that multiple adjusting rods can adjust the radius with the rotating shaft as the center, and the position of the drill rod changes synchronously. In this process, the second hydraulic rod drives the jacket to move longitudinally, driving the multi-stage adjusting gear to move longitudinally, and then driving the disc gears of different radii of the multi-stage adjusting gear to mesh with the driven gear after the adjustment position, providing driving force for the drill rod; S3: During the drilling process of new energy vehicles, the wheel hub is placed on the processing table, and the fixed motor drives the screw rod to rotate. Because the threads on the outer wall of the screw rod are relatively distributed, and the lower end of the stroke block is slidably guided by the guide rail, the stroke plate on the outer wall of the screw rod is driven to move relative or away from each other. At the same time, when the screw rod rotates, it drives the bevel gear rod to rotate, and the bevel gear rod pushes the bevel gear rod to rotate, which drives the screw rod to rotate. Through the threads on the outer wall of the screw rod, the stroke plates on the outer wall of the screw rod are driven to move relative or away from each other. The four stroke plates are distributed in a circular array, and the stroke plates distributed in the circular array support the inner wall of the wheel hub at multiple points, thereby realizing the fixation of the wheel hub during processing and providing a stable foundation for the drilling of the wheel hub. Because the position of the stroke plate is adjustable, wheel hubs of different radii are supported.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention uses a drill rod to drill the screw hole. During the processing, the drill rods are distributed in a circular array, and drilling is performed at multiple positions distributed in the circular array at the same time, so that the drilling is completed in one step, avoiding multiple drilling operations by the same equipment. During the wheel hub drilling process, the drilling efficiency of the new energy vehicle wheel hub is improved, and the convenience of drilling is improved. At the same time, the spacing of the drill rods is adjustable through a multi-stage spacing gear, thereby realizing flexible drilling of wheels of different specifications.

[0035] When drilling, the wheel hub model will change. Different new energy vehicles and wheel hubs have different radii of the fixings installed. The adjusting motor 19 drives the adjusting gear 20 to rotate, and the force is transmitted to the adjusting disk 25 through the connecting rod 27, and the stroke rod 28 is squeezed through the adjusting groove 26 to achieve position adjustment, ensuring that multiple adjusting rods perform radius adjustment and the position change of the drill rod 24 are synchronized, so as to achieve drilling processing at different radius points; A fixed motor 8 is arranged at the upper end of the base 3, and a screw rod 6 with relatively distributed outer wall threads is arranged at the output end of the fixed motor 8, and a travel plate 12 is installed on the outer wall thread of the screw rod 6.

[0040] Example

[0041] A new energy vehicle wheel hub processing method, the wheel hub processing method steps are as follows: S1: It is worth noting that the multi-stage pitch-adjustable gear 31 is composed of a disc gear distributed longitudinally and having a radius decreasing from top to bottom. The multi-stage pitch-adjustable gear 31 is meshed with the driven gear 23. Under the driving force of the drilling motor 17, the multi-stage pitch-adjustable gear 31 and the driven gear 23 are driven to rotate through the rotating shaft 30, thereby driving the drill rod 24 to rotate. At the same time, the hydraulic rod 15 drives the installation box 4 to move longitudinally, thereby driving the drill rod 24 to descend, and drilling the wheel hub at four points at the same time; S2: When the model of the wheel hub changes, the position of the mounting hole will also change. At this time, the adjusting motor 19 drives the adjusting gear 20 to rotate and push the gear ring 21. The rotational force of the gear ring 21 acts on the adjusting disk 25 through the connecting rod 27. During the rotation of the adjusting disk 25, the internal adjusting groove 26 squeezes the stroke rod 28, and the position of the stroke rod 28 changes. At the same time, the adjusting rod rolls and fits with the ring seat 22 through the top ball 32 and the bottom ball 13. Then, when the adjusting groove 26 squeezes the stroke rod 28 to adjust the position, the horizontal height of the adjusting rod remains unchanged, ensuring that multiple adjusting rods are adjusted in radius with the rotating shaft 30 as the center, and the position of the drill rod 24 changes synchronously. In this process, the hydraulic rod 18 drives the jacket to move longitudinally, driving the multi-stage pitch-adjusting gear 31 to move longitudinally, and then driving the disc gears of different radii of the multi-stage pitch-adjusting gear 31 to mesh with the driven gear 23 after the adjustment position, providing driving force for the drill rod 24. S3: During the drilling process of new energy vehicles, the wheel hub is placed on the processing table 2, and the fixed motor 8 drives the screw 6 to rotate. Because the threads on the outer wall of the screw 6 are relatively distributed, and the lower end of the travel block is slidably guided by the guide rail 15, the travel plate 12 on the outer wall of the screw 6 is driven to move relative to or away from each other. At the same time, when the screw 6 rotates, it drives the bevel gear 9 to rotate, and the bevel gear 9 pushes the bevel gear 2 10 to rotate, driving the screw 2 7 to rotate, and through the relatively distributed threads on the outer wall of the screw 2 7, the travel plate 12 on the outer wall of the screw 2 7 is driven to move relative to or away from each other. The four travel plates 12 are distributed in a circular array, and the travel plates 12 distributed in the circular array support the inner wall of the wheel hub at multiple points, thereby realizing the fixation of the wheel hub during processing and providing a stable foundation for the drilling of the wheel hub. Because the position of the travel plate 12 is adjustable, wheel hubs of different radii are supported.

At the same time, the hydraulic rod (5) drives the mounting box (4) to move longitudinally, thereby driving the drill rod (24) to descend, and drilling the wheel hub at four positions at the same time; S2: When the model of the wheel hub changes, the position of the mounting hole will also change. At this time, the adjusting motor (19) drives the adjusting gear (20) to rotate and push the ring gear (21). The rotational force of the ring gear (21) acts on the adjusting disk (25) through the connecting rod (27). During the rotation of the adjusting disk (25), the internal adjusting groove (26) squeezes the travel rod (28), and the position of the travel rod (28) changes. At the same time, the adjusting rod rolls and fits with the ring seat (22) through the top ball (32) and the bottom ball (13). Then, when the adjustment groove (26) squeezes the stroke rod (28) to adjust the position, the horizontal height of the adjustment rod remains unchanged, ensuring that the multiple adjustment rods can adjust the radius with the rotating shaft (30) as the center, and the position of the drill rod (24) changes synchronously. During this process, the second hydraulic rod (18) drives the jacket to move longitudinally, driving the multi-stage adjustable gear (31) to move longitudinally, thereby driving the disc gears of different radii of the multi-stage adjustable gear (31) to mesh with the driven gear (23) after the adjustment position, thereby providing driving force for the drill rod (24); S3: During the drilling process of the new energy vehicle, the wheel hub is placed on the processing table (2), and the fixed motor (8) drives the screw rod 1 (6) to rotate. Because the threads on the outer wall of the screw rod 1 (6) are relatively distributed, and the lower end of the stroke block is slidably guided by the guide rail (15), the stroke plate (12) on the outer wall of the screw rod 1 (6) is driven to move relative to or away from each other. At the same time, when the screw rod 1 (6) rotates, the bevel gear 1 (9) is driven to rotate. The bevel gear 1 (9) drives the bevel gear 2 (10) to rotate, driving the screw rod 2 (7) to rotate. Through the threads on the outer wall of the screw rod 2 (7) that are relatively distributed, the stroke plate (12) on the outer wall of the screw rod 2 (7) is driven to move relative to or away from each other. The four stroke plates (12) are distributed in an annular array. The stroke plates (12) distributed in the annular array support the inner wall of the wheel hub at multiple points, thereby achieving fixation during the wheel hub processing process and providing a stable foundation for the drilling of the wheel hub. Because the position of the stroke plate (12) is adjustable, wheel hubs of different radii are supported.
