Description

Technical Field

[0001] This utility model relates to the field of robotic arm replacement technology, specifically to a robotic arm mechanism for quick replacement in a finishing mill. Background Technology

[0002] In the steel rolling production field, the finishing mill is a key piece of equipment. Its rolling mode needs to be frequently switched according to the requirements of different specifications and materials of rolled products. The robotic arm mechanism is the core execution unit for replacing core components such as rolls and guides in the finishing mill. Its replacement efficiency and stability directly determine the continuous operation capability and production accuracy of the production line.

[0003] Currently available robotic arm mechanisms for finishing mills generally suffer from the following technical pain points: Firstly, traditional robotic arms mostly adopt an integrated rigid connection structure. When switching between different rolling modes, the entire robotic arm frame needs to be disassembled and reassembled. This not only requires multiple operators to work together, but also requires repeated calibration of the parts during the replacement process. A single replacement usually takes 1-2 hours, which seriously affects the effective working time of the production line. Secondly, the positioning accuracy of existing mechanisms relies on manual adjustment and lacks standardized limit and guide structures. After long-term high-frequency use, positioning deviations are easily caused by component wear, which in turn leads to safety hazards such as out-of-tolerance dimensional accuracy of rolled pieces and equipment collisions. Thirdly, most robotic arm mechanisms use direct shaft connection for rotation and deflection components without independent bearing support and protection structures. In the high-temperature and dusty rolling environment, the wear rate of components is accelerated, which not only shortens the service life of the mechanism but also requires frequent shutdowns for maintenance, further increasing the production costs of enterprises. Utility Model Content

[0004] Technical problems to be solved In view of the above-mentioned shortcomings of the existing technology, the present invention provides a robotic arm mechanism for quick change of finishing mill, which can effectively solve the problems in the existing technology.

[0005] Technical solution This utility model provides a quick-change robotic arm mechanism for a finishing mill, including a spacer plate with a slot in the middle. Mounting assemblies are provided on both sides of the top of the spacer plate, and a deflection frame is installed within each mounting assembly. A base plate is provided at the bottom of each mounting assembly. Each mounting assembly includes two sets of side plates, a connecting cylinder located inside the side plates, and a limiting plate fixed to the top of the side plates. The deflection frame includes a deflection rod and a rotating shaft sleeved at the bottom of the deflection rod. The rotating shaft is sleeved inside the connecting cylinder, and the base plate is fixed to the bottom of the side plates.

[0006] Furthermore, a bearing structure is fitted into the middle of the base plate.

[0007] Furthermore, multiple sets of side holes are formed in the middle of the two sets of side plates.

[0008] Furthermore, an arc-shaped slot structure is provided on one side of the limiting plate, and the connecting cylinder is disposed at one end of the same group of side holes.

[0009] Furthermore, the base plate is disposed within the spacer groove.

[0010] Furthermore, the tip of the deflection rod protrudes from the top of the side plate.

[0011] Beneficial effects In this invention, the auxiliary disassembly and assembly mechanism of the split-type manipulator enables the replacement of vertical rolls without disassembling the guide beam and the rolling mill, thereby reducing the time for replacing vertical rolls and lowering production costs. In specific operation, the rolling mill base is separated from the rolling mill body and dropped into the auxiliary manipulator; after the positioning key on the auxiliary manipulator matches the rolling mill positioning groove, the rolling mill is lowered and the locking bolts are tightened; after the pressure of the ingot beam hydraulic cylinder is released, the operation to replace the vertical roll begins.

[0012] In this device, the mechanism adopts a modular combination design of "spacer plate + mounting components + deflection frame" and a rotatable connection structure of "deflection rod - rotating shaft - connecting cylinder" in the deflection frame, which realizes the rapid disassembly and assembly and angle adjustment of the core components of the robot arm: when changing the rolling mode, it is not necessary to disassemble the entire mechanism. The angle of the deflection frame can be adjusted by cooperating the rotating shaft and the connecting cylinder, or the mounting components can be directly replaced modularly to complete the switch. Compared with the 1-2 hour changeover time of the traditional mechanism, the downtime of the production line is greatly reduced, and the equipment utilization rate and production efficiency are significantly improved. Meanwhile, the matching design of the interval groove in the middle of the spacer plate and the base plate provides a standardized positioning benchmark for the installation components, avoiding the tedious steps of manual calibration and further accelerating the replacement speed. On the one hand, multiple sets of side holes are opened in the middle of the two sets of side plates in the installation components, and the connecting cylinder is fixed to one end of the same set of side holes. Through the multi-position design of the side holes, the installation position of the connecting cylinder can be precisely adjusted according to different rolling requirements, thereby achieving precise positioning of the deflection frame. On the other hand, the arc-shaped slotted structure on one side of the limiting plate can limit and constrain the rotation angle of the deflection rod, preventing positioning deviation caused by excessive rotation of the deflection frame. At the same time, the arc-shaped structure can reduce frictional wear between the deflection rod and the limiting plate, ensuring long-term stability of positioning accuracy. In addition, the bearing structure sleeved in the middle of the base plate not only reduces the frictional resistance between the base plate and other components, but also ensures the rotational concentricity of the mechanism during high-frequency use, further improving the overall positioning accuracy, effectively avoiding rolling quality problems caused by positioning deviations, and ensuring the stability of product quality.
