Description

Smart surface grinder

technical field

The invention relates to the technical field of plane processing, in particular to an intelligent plane grinding method.

Background technique

Surface processing is an industrial basic technology. The common processing methods are mainly milling and grinding. The grinding method can process materials with higher hardness, such as alloys and high carbon steel, and can also process brittle materials, such as glass, granite, marble and other materials.

technical problem

Existing surface grinding equipment can rarely process large surfaces or the precision of the processed large surfaces cannot meet certain requirements, and there are problems such as difficult operation, multi-person operation, and time-consuming and labor-intensive problems.

technical solution

In view of the deficiencies of the existing processing methods, the present invention aims to provide an intelligent surface grinding method, which can process large-sized surfaces. It is mainly operated by mechanical intelligence, saves time and effort, and the error of manual grinding can be controlled within 0.003mm~0.004mm. The precision of mechanical grinding can be further improved, and it has strong functionality.

In order to achieve the above object, the present invention adopts the following method: an intelligent surface grinding method, including a workbench, a clamping robot, and a grinding head. The workbench has a base surface, and the plane precision level of the base surface reaches the micron level. Rotate and adjust the height up and down, at least there is an electric grinding wheel clamping manipulator, and the plane is quickly ground and processed by the clamping robot intelligently clamping the electric grinding wheel; after the detection device on the workbench is used to detect the plane, the controller can be used to control the robot to continue processing the uneven plane, and the worker can also use the grinding head to further process the processing plane; the grinding head has a replaceable grinding disc and a long rod for holding.

Preferably, the clip-sending robot has a five-axis plane joint, and the rotatable angle is greater than 180 degrees.

Beneficial effect

The automatic grinding of the feeding robot greatly saves the time required for processing, so that subsequent processing only requires a small amount of grinding of uneven positions, and the flatness detection device is used to conveniently detect the uneven positions. In this way, large planes can be finely ground. While saving time and effort, the precision of the processed plane can reach the micron level, achieving the purpose of the invention.

BEST MODE FOR CARRYING OUT THE INVENTION

In a specific embodiment of the present invention, referring to Fig. 1, the processing plane is a billiard tabletop for billiard games, the plane size is about 2000×1000mm, and the material is a kind of stone slab. After it is installed and fixed on the workbench, the feeding robot performs the initial grinding process according to the pre-programmed program, which takes a very short time. , or by manually operating the grinding head, the said grinding head can replace the grinding disc, and can be easily replaced at any time after wear. During the grinding process, the flatness of the plane can be detected by the detection device at any time. If there is still unevenness, repeat the above steps. The size error of the large plane processed in this way can be accurate to 0.003mm, which meets the requirements of the billiard table top.

Embodiments of the present invention

In another embodiment of the present invention, the processing plane is a flat measuring tool bottom plate made of a high-density material, which is processed by a feeding robot to ensure a high degree of standardization of the processing plane, and each processing plane has the same size specification and accuracy, meeting the quality requirements of the main engine factory.

In another embodiment, the processing plane is a three-coordinate detector substrate made of marble. In actual operation, the detection device is used to detect the processing plane multiple times, and the grinding head is used to repeatedly grind until the precision of the polished processing plane reaches the micron level, which meets the precision requirements.

Industrial Applicability

Any large-sized plane can be ground in this way and achieve better precision. The flatness detection device is easy to manufacture, the principle is simple, and the dyeing material is cheap and durable, which makes the present invention have good practicability and easy implementation.
