[0003] In the outer ring processing of the wheel hub, the iron sheet needs to be rolled and pressed into a circular outer ring first, and then the joint of the circular outer ring is welded. The weld seam needs to be ground. The existing grinding method uses traditional manual grinding, which is inefficient and prone to uneven grinding. In view of the above shortcomings, this utility model proposes a wheel hub weld seam grinding device. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a wheel hub weld grinding device to solve the existing problems.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a wheel hub weld grinding device, the structure of which includes a base, and a processing frame is vertically arranged on the upper rear side of the base, and a plurality of first slide rails are horizontally arranged on the front side of the processing frame.

Multiple first telescopic devices are provided on the front and rear sides of the bottom center of the first roller conveyor frame, and multiple stabilizing slide rods are vertically provided on the left side of the bottom surface of the second roller conveyor frame, with the other end of each stabilizing slide rod penetrating through the outer frame.

[0008] A further improvement is that the drive assembly includes a second telescopic member, and a push-pull slider is provided on the bottom surface of the second telescopic member. A second slide rail is laterally sleeved on the lower end of the push-pull slider. A fixed seat is provided on the right end of the second telescopic member, and the fixed seat is fixedly connected to the base. A rack for meshing with a gear is provided on the rear side of the second telescopic member.

[0009] A further improvement is that the drive assembly drives the gears to rotate left and right, causing the gripper to rotate 90° to the left and right on the two rotating seats.

[0010] A further improvement is that the pressing mechanism includes a mounting base, and a rotator is provided on the top surface of the mounting base, and a bidirectional telescopic device is provided laterally on the top surface of the rotator.

[0012] The beneficial effects of the utility model are:

[0013] This utility model provides a wheel hub weld grinding device. Through a structural combination design of a base, processing frame, first slide rail, conveyor frame assembly, gripper flipping mechanism, pressing mechanism, first grinding end, and second grinding end, a wheel hub weld grinding device is constructed. The operator only needs to place the wheel hub on the left side of the first roller conveyor frame. The first roller conveyor frame automatically conveys the wheel hub to the right, directly above the pressing mechanism, and then descends. This facilitates the pressing mechanism's fitting of the wheel hub and pressing against the inner ring of the wheel hub. The pressing mechanism also has a rotation and weld seam sensor alignment function, allowing the first grinding end to align with the outer ring weld of the wheel hub for grinding after descending. The gripper flipping mechanism's clamping and flipping functions allow the wheel hub to be flipped from the first roller conveyor frame onto the second roller conveyor frame and held firmly in place. This facilitates the second grinding end's descent to grind the inner ring weld of the wheel hub. Finally, the second roller conveyor frame automatically discharges the material to the right. This grinding process is more precise, more efficient, and highly automated. Attached Figure Description

The gripper flipping mechanism 5 includes a gripper 51, with two rotating seats 52 sleeved on the front and rear sides of the gripper 51. A gear 53 is sleeved on the front side of the gripper 51, and a drive assembly 54 meshes with the lower end of the gear 53.

[0020] The conveyor frame assembly 4 includes an outer frame 41, and a first roller conveyor frame 42 is movably mounted on the left side of the top surface of the outer frame 41, and a second roller conveyor frame 43 is movably mounted on the right side of the top surface of the outer frame 41. Multiple first telescopic devices 44 are provided on the front and rear sides of the middle of the bottom surface of the first roller conveyor frame 42, and multiple stabilizing slide rods 45 are vertically provided on the left side of the bottom surface of the second roller conveyor frame 43. The other end of each stabilizing slide rod 45 passes through the outer frame 41.

[0021] The drive assembly 54 includes a second telescopic member 541, and a push-pull slider 542 is provided on the bottom surface of the second telescopic member 541. A second slide rail 543 is horizontally sleeved at the lower end of the push-pull slider 542. A fixed seat 544 is provided at the right end of the second telescopic member 541. The fixed seat 544 is fixedly connected to the base 1. A rack 545 for meshing with the gear 53 is provided on the rear side of the second telescopic member 541.

[0022] The drive assembly 54 pushes the gear 53 to rotate from left to right, causing the gripper 51 to rotate 90° to the left and right on the two rotating seats 52.

[0023] The pressing mechanism 6 includes a mounting base 61, and a rotator 62 is provided on the top surface of the mounting base 61. A bidirectional telescopic device 63 is provided laterally on the top surface of the rotator 62. Multiple pressing heads 64 are provided on the left and right sides of the bidirectional telescopic device 63. Each pressing head 64 is made of rubber. A weld seam sensor 65 is provided on the upper left side of the mounting base 61.

[0024] Working principle:

[0025] First, the first roller conveyor frame 42 is raised to a horizontal height above the top surface of the pressing mechanism 6 by extending two first telescopic devices 44. Then, the wheel hub is placed on the left side of the first roller conveyor frame 42 and conveyed to the right to be directly above the pressing mechanism 6. Then, the first telescopic devices 44 retract, so that the wheel hub fits onto the outer ring of the pressing mechanism 6. Then, the bidirectional telescopic device 63 extends and retracts, so that the two pressing heads 64 press against the middle of the inner ring of the wheel hub for pressing and fixing. Then, the rotator 62 drives the wheel hub to turn so that the weld seam sensed by the weld seam sensor 65 can be detected. After the first grinding end 7 descends, it can be aligned with the weld seam of the outer ring of the wheel hub for grinding. After the outer ring of the wheel hub is ground, the drive is used to grind the weld seam. Driven by component 54, the gripper 51 rotates 90° to the left via gear 53. It should be noted that the gripper 51 is initially set to vertical. Then, the gripper 51 clamps the front and rear sides of the outer ring of the hub. Then, the pressing mechanism 6 resets and releases the pressing on the inner ring of the hub. Then, driven by component 54, the gripper 51 rotates 90° to the right via gear 53, causing the hub to rotate onto the second roller conveyor frame 43. When the second grinding end 8 grinds the weld seam of the inner ring of the hub, the gripper 51 keeps clamping the hub. After the second grinding end 8 completes the grinding, the gripper 51 opens, and then the second roller conveyor frame 8 conveys the hub to the right for discharge.
