Description

Technical Field

[0001] The utility model belongs to the technical field of wheel spoke processing, in particular to a wheel spoke skeleton slag removal device. Background Art

[0002] The wheel hub is the core component of a car tire, serving as the tire's structural framework and supporting the vehicle's weight. During the wheel hub production process, the rim, spokes, and other components are assembled sequentially according to the required components, and then welded together to form the hub.

[0003] Specifically, during the spoke production process, spoke blanks are produced through casting. During the casting process, slag lumps are easily left on the spokes, resulting in a raised slag structure. Therefore, the slag lumps must be removed from the produced spokes.

[0004] Specifically, during the spoke production process, spokes are often loaded and unloaded back and forth between different production equipment using a robotic arm. Therefore, this back-and-forth loading and unloading process not only streamlines production but also significantly improves production efficiency. Slag ladles are generated during the casting process.

[0005] If traditional grinding and polishing methods are used, it will not only be difficult to position and polish spokes with high irregularities, but once polishing equipment is used, it will be necessary not only to design corresponding tooling and fixtures and other positioning structures, but also to load and unload the spokes into the polishing equipment, which will greatly increase the number of production operations and seriously reduce production efficiency.

[0006] If the slag bags on the spokes can be removed quickly and effectively during the production process when the robotic arm is transferring materials, it will not only greatly increase production efficiency, but also maintain the smoothness of the entire production and simplify the production steps.

[0008] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0009] A spoke skeleton slag removal device includes a mechanical arm material grabbing mechanism, the mechanical arm material grabbing mechanism includes a mechanical arm and a spoke locking clamp assembly installed on the mechanical arm;

[0010] and a slag removal clamp that cooperates with the robotic arm's material grabbing mechanism;

[0014] The slag bag removal fixture includes a plurality of striker bars. During the slag bag removal process, the gripping mechanism of the robotic arm strikes the grasped wheel spokes between the striker bars, and the residual slag bags on the wheel spokes are knocked away by the impact of the striker bars.

[0015] Preferably, the locking clamp frame includes a locking mounting seat fixedly mounted on the robotic arm, the locking mounting seat is fixedly connected to the locking clamp arm, and the double-grabbing claw cylinder is fixedly mounted at the bottom position of the locking clamp arm.

[0016] Preferably, a connecting and fixing rib is fixedly connected to the top of the locking clamp arm, and the connecting and fixing rib is fixedly connected to the locking mounting seat.

[0017] Preferably, a cylinder mounting bracket is fixedly mounted on the bottom of the locking clamp arm, and the cylinder of the double-grabbing claw cylinder is fixedly mounted on the cylinder mounting bracket.

[0018] Preferably, the grab arm mounting portion comprises a rectangular portion fixedly mounted on the piston clamping jaw by a plurality of mounting bolts, the rectangular portion is integrally formed with a trapezoidal portion, and the trapezoidal portion is integrally formed with the grab arm portion.

[0025] The utility model has the following beneficial effects:

[0026] 1. During operation, when the dual-claw pneumatic cylinder drives the two piston grippers, carrying the gripping arms and gripping heads, approach each other until the arc-shaped gripping grooves on the gripping heads lock onto the center axis of the spokes, thereby stably gripping the spokes. Because the spokes are gripped tightly, they are less likely to loosen when impacting the slag removal package fixture, significantly improving the stability of the slag removal package.

[0027] 2. During operation, after the robotic arm secures the spokes with the spoke locking clamp assembly, it then moves vertically downward with the center of the base platform as the reference point until it rapidly descends between the striker bars. Since the slag bag is a protruding structure on the spoke, the protruding slag bag is blocked by the striker bar and impacts the striker bar. Under the impact, the slag bag is removed (the thin slag bag is easily detached under the impact), while the normal part of the spoke passes through the striker bar without hindrance. The above method can quickly remove the slag bag on the spoke. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Example 1

[0039] like Figure 1-5 As shown, a spoke skeleton slag bag removal device includes a robotic arm grabbing mechanism, which includes a robotic arm 301 (the robotic arm 301 is a conventional robotic arm 301 for grabbing materials disclosed in the prior art) and a spoke locking clamp assembly 3 installed on the robotic arm 301; and a slag bag removal clamp that cooperates with the robotic arm 301 grabbing mechanism.

[0040] Specifically, the spoke A is clamped by the spoke locking assembly 3 and quickly removed by the slag removal fixture. The gripping mechanism of the robotic arm 301 then transfers the spoke A to the next working device. During this process, the robotic arm 301 grabs the material from the previous working device and quickly strikes the spoke A against the slag removal fixture to remove the slag. Without loosening the spoke A, the spoke is then transferred to the next working device. This approach significantly simplifies the production process, enabling the entire process to be completed quickly and efficiently.

[0041] Specifically, the spoke locking clamp assembly 3 includes a locking clamp frame 31 installed on the mechanical arm 301; the specific structure of the locking clamp frame 31 is: the locking clamp frame 31 includes a locking mounting seat 311 fixedly installed on the mechanical arm 301, and the locking mounting seat 311 is fixedly connected to the locking clamp arm 312.

[0042] Meanwhile, a dual-claw cylinder 32 is mounted at the bottom of the clamping frame 31 (the dual-claw cylinder 32 is fixedly mounted at the bottom of the clamping arm 312). Specifically, a cylinder mounting bracket 323 is fixedly mounted at the bottom of the clamping arm 312, and the cylinder of the dual-claw cylinder 32 is fixedly mounted on the cylinder mounting bracket 323.

[0043] At the same time, in order to increase the structural stability of the locking clamp frame 31 , a connecting and fixing rib is fixedly connected to the top of the locking clamp arm 312 , and the connecting and fixing rib is fixedly connected to the locking mounting seat 311 .

[0044] The two piston clamps 321 of the double-gripping claw cylinder 32 are respectively fixedly assembled with a gripping arm 33 for gripping the wheel spokes; the shape of the gripping arm 33 is:

[0045] The gripping arm 33 includes a gripping arm mounting portion 331 mounted on the piston jaw. This gripping arm mounting portion 331 is integrally formed with a gripping arm portion 332. A gripping head 333 is fixedly mounted on this gripping arm portion 332 (specifically, the gripping arm portion 332 is fastened to the gripping head 333 via several bolts). The gripping head 333 is provided with an arcuate gripping groove. Specifically, the gripping arm mounting portion 331 comprises a rectangular portion fixedly mounted on the piston jaw 321 via several mounting bolts. This rectangular portion is integrally formed with a trapezoidal portion, which is integrally formed with the gripping arm portion 332. This structure of the gripping arm 33 not only provides high structural stability but also enables highly stable gripping of the spoke A during operation.

[0046] During operation, when the dual-gripping claw cylinder 32 is driven, the two piston claws, carrying the gripping arms 33 and gripping heads 333, approach each other until the arc-shaped gripping groove on the gripping head 333 locks onto the central axis of the spoke A. This ensures a stable grip of the spoke A. Because the spoke A is gripped securely, it is unlikely to loosen when it strikes the slag removal ladle fixture, significantly improving the stability of the slag removal ladle.

[0047] Example 2

[0048] like Figure 1-5 As shown, based on the structure of Example 1, the slag bag removal fixture of this embodiment includes a plurality of impact rods 35 (the impact rods 35 are distributed circumferentially on the top edge of the base platform). During the slag bag removal process, the gripping mechanism of the robot arm 301 impacts the grasped spoke A between the impact rods 35. Under the impact of the impact rods 35, the residual slag bag on the spoke A is knocked away.

[0049] Specifically, the slag removal fixture also includes a base 351 fixedly connected to the striker 35; the bottom of the base 351 is fixedly connected to a bottom bracket. The bottom bracket includes an inclined platform 34. The base 351 is fixedly connected to the top of the inclined platform 34 via a plurality of vertical fixed connecting columns; the bottom of the inclined platform 34 is fixedly connected to a connecting column 341, and the bottom of the connecting column 341 is fixedly connected to the base.

[0050] During operation, after the robot arm 301 grasps the wheel spoke through the spoke locking clamp assembly 3, the robot arm 301 moves vertically downward with the center of the base platform 351 as the reference point until it quickly descends between the striker bars 35. Since the slag bag is a protruding structure on the wheel spoke A, the protruding slag bag is blocked by the striker bars 35 and hits the striker bars 35. Under the impact, the slag bag is removed (the slag bag is thin and easily falls off under the impact), while the normal part of the wheel spoke A passes through the striker bars 35 without obstruction. In this way, the slag bag on the wheel spoke is quickly removed.

[0051] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
