Description

Floating grinding device Technical Field

[0001] This utility model belongs to the field of polishing technology, and relates to a polishing device, particularly a floating polishing device. Background Technology

[0002] In the field of automated grinding and milling of metal parts, floating grinding tools are often integrated into the end effector of robots to clamp grinding heads such as carbide rotary files to chamfer or deburr metal parts. However, existing floating grinding tools have grinding heads and grinding tools that are concentric and coaxial, and the grinding head shank is relatively short. The grinding floating mechanism, clamping and connecting mechanism, and robot six-axis are all located directly behind the central axis of the grinding shank and are very close to the grinding head. This results in severe interference between the mechanism behind the grinding head and the part when grinding with the side of the grinding head, which severely limits the scope of use, especially when grinding complex parts over a large area on the same horizontal plane. Summary of the Invention

[0003] In order to solve the above-mentioned problems in the technical background, the present invention provides a floating polishing device that can minimize interference with the object to be polished.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A floating grinding device is characterized in that: the floating grinding device includes a bent grinding machine and a linear drive mechanism connected to the bent grinding machine; the linear drive mechanism drives the bent grinding machine to move freely along the axial direction of the linear drive mechanism.

[0006] The aforementioned floating grinding device also includes a locking fastener; the bent grinding machine is connected to the linear drive mechanism via the locking fastener.

[0007] The aforementioned floating grinding device also includes an electro-proportional valve and a frequency converter; the electro-proportional valve is connected to a linear drive mechanism; and the frequency converter is connected to a bend grinding machine.

[0008] The aforementioned linear drive mechanism is a slide cylinder or a rodless cylinder.

[0009] The aforementioned elbow grinder is either a pneumatic grinder or an electric grinder.

[0010] The aforementioned floating grinding device also includes a connecting plate, which is L-shaped in general, and the linear drive mechanism is fixedly mounted on the connecting plate.

[0011] The aforementioned floating grinding device also includes a quick-change disc connecting plate located on top of the connecting plate.

[0012] The aforementioned floating grinding device also includes a quick-change disc master disc mounted on the quick-change disc connecting plate.

[0013] The aforementioned quick-change disc mother plate integrates an airflow passage and a control line pipeline; the airflow passage is connected to the elbow grinder and / or the linear drive mechanism; the control line pipeline is connected to the elbow grinder and / or the linear drive mechanism.

[0014] The aforementioned floating polishing device also includes a protective cover that surrounds the linear drive mechanism.

[0015] The advantages of this utility model are:

[0016] This invention provides a floating grinding device, including a bent grinding machine and a linear drive mechanism connected to the bent grinding machine. The linear drive mechanism drives the bent grinding machine to move freely along the axial direction of the linear drive mechanism. This invention first employs a bent grinding machine and then a linear drive mechanism. The linear drive mechanism allows the bent grinding machine to move along the axial direction of the linear drive mechanism, achieving floating of the grinding head. This enables adaptive grinding of complex curved surfaces and prevents mechanical collisions. Simultaneously, since the linear drive mechanism is located far above the grinding head, interference between the mechanism and the parts is minimized, allowing for grinding and milling of large-area planar areas of complex parts. Furthermore, the floating grinding device provided by this invention includes a quick-change master plate that can be connected to a robot, facilitating direct and rapid robot gripping of the floating grinding device, making it convenient to use.

[0022] Referring to Figure 2, this invention provides a floating grinding device, which includes a bent grinding machine 1 and a linear drive mechanism connected to the bent grinding machine 1. The linear drive mechanism drives the bent grinding machine 1 to move freely along the axial direction of the linear drive mechanism. This invention first uses a bent grinding machine and simultaneously employs a linear drive mechanism. The linear drive mechanism enables the bent grinding machine to move along the axial direction of the linear drive mechanism (i.e., the linear drive mechanism can control the bent grinding machine to float linearly in a direction perpendicular or approximately perpendicular to the grinding head shaft and tool holder line), thus achieving the floating of the grinding head. This allows for adaptive grinding of complex curved surfaces and prevents mechanical collisions. Furthermore, since the linear drive mechanism is located above the grinding head, interference between the mechanism and the parts is minimized, allowing for grinding and milling of a large area of ​​the planar surface of complex parts.

[0023] To more securely connect the elbow grinder 1 to the linear drive mechanism, the floating grinder device provided by this utility model also includes a locking fastener 2; the elbow grinder 1 is connected to the linear drive mechanism through the locking fastener 2. In the elbow grinder, the grinding head forms an angle with the driving direction of the linear drive mechanism; for example, as shown in Figures 1 and 2, the grinding head forms a right angle with the driving direction of the linear drive mechanism.

[0024] For example, the floating grinding device also includes an electro-proportional valve and a frequency converter; the electro-proportional valve is connected to a linear drive mechanism; the frequency converter is connected to the elbow grinding machine 1. The linear drive mechanism can be a slide cylinder 3 or a rodless cylinder. The elbow grinding machine 1 is a pneumatic grinding machine or an electric grinding machine. Therefore, the electro-proportional valve can conveniently control the floating force of the linear drive mechanism, or conveniently control the rotational speed of the elbow grinding machine 1. For example, when the elbow grinding machine is electric, the operating frequency of the elbow grinding machine can also be controlled by the frequency converter.

[0025] Referring to Figure 2, the floating grinding device provided by this utility model also includes a connecting plate 4, which is L-shaped in general. The linear drive mechanism is fixedly mounted on the connecting plate 4. For example, the electric proportional valve and / or frequency converter can be directly mounted on the connecting plate 4, or they can be directly integrated into the robot. The specific setting method can be adjusted according to the actual working conditions, and will not be described in detail here.

[0026] To facilitate seamless connection with additional robots, such as a six-axis robot, the floating grinding device provided by this invention also includes a quick-change disc connecting plate 5 mounted on top of the connecting plate 4. A quick-change disc mother plate 6 is provided on the quick-change disc connecting plate 5 for rapid connection with the robot. This allows the robot to quickly grasp the invention, thereby further improving work efficiency. For example, the quick-change disc connecting plate 5 may be T-shaped or have lugs, allowing the entire invention to be placed on a support within the equipment tool library, facilitating robot retrieval from the tool library.

[0027] It should be noted that the quick-change disc mother plate 6 integrates airflow passages and control lines; the airflow passages are connected to the elbow grinder 1 and / or the linear drive mechanism; the control lines are connected to the elbow grinder 1 and / or the linear drive mechanism. For example, when the robot grasps this utility model, its operation involves the robot setting the floating grinding force and the rotation speed of the elbow grinder via the PLC; the robot then supplies air and electricity to the elbow grinder 1 and / or the linear drive mechanism through the airflow passages and control lines on the quick-change disc mother plate 6, running the grinding program and beginning the grinding of the parts.

[0028] Referring to Figure 1, the floating grinding device provided by this utility model also includes a protective cover 7 covering the outside of the linear drive mechanism, which can prevent grinding dust from entering the cylinder.

[0029] Referring to Figure 3, A represents the prior art, which shows that the lateral floating grinding head can only chamfer, while end face grinding and plane grinding suffer from severe interference; B represents the technical solution provided by this utility model, which shows that it can handle chamfer, end face grinding, and plane grinding without any interference.
