Description

Technical Field

[0001] The utility model relates to the technical field of three-axis motion control devices, in particular to a three-axis motion control device. Background Technique

[0002] Three-axis motion refers to the motion of an object in three mutually perpendicular directions. These three directions are usually defined as the X-axis, Y-axis, and Z-axis. In the fields of engineering and machinery, three-axis motion is usually used to describe the position and motion state of an object in three-dimensional space. A three-axis motion control device generally refers to a device that can control the motion of an object in three axial directions. Three-axis motion control devices are usually used in the fields of industrial automation, robotics, aerospace, medical equipment, and scientific research. A three-axis motion control device can separately control the motion of an object in three independent axial directions.

[0003] When a traditional three-axis motion control device is in use, it lacks the fixation of the object during the motion process. In a three-axis motion control system, especially during high-precision machining or complex motion paths, a fixing structure can ensure that the working object does not move or distort during the motion process. This is crucial for ensuring machining accuracy and maintaining product quality. Therefore, a three-axis motion control device is proposed.

[0004] In a description device of a three-axis motion control experimental platform disclosed in the publication number CN206938293U, although the description device of the three-axis motion control experimental platform includes an L-shaped plate, a top cover, and a spring; the L-shaped plate includes a bottom plate and a side plate; the top cover is arranged on the top of the side plate; the top cover is fixed on the side plate of the L-shaped plate through hexagon bolts passing through a slot and a screw hole; the spring is arranged in the large hole of the stepped hole; the description device is fixed on the Z-axis plate of the three-axis motion control experimental platform through four fastening screw holes and fastening screws on the side plate of the L-shaped plate. There is also an adjusting screw hole in the bottom plate that communicates with the through hole at a 90° angle. After the three-axis motion control experimental platform is installed with the description device, the problem of not being able to draw the motion trajectory before is solved. It can not only judge whether the input program is correct according to the drawn motion trajectory, but also draw the required graphics or characters.

[0005] Although the above patent solves the problem of not being able to draw the motion trajectory after the three-axis motion control experimental platform is installed with the description device, and it can not only judge whether the input program is correct according to the drawn motion trajectory, but also draw the required graphics or characters; however, this device lacks an angle adjustment function. The angle adjustment structure allows for fine adjustment of the angle to ensure that the working device or tool can be accurately positioned to the target position. This is crucial for precision machining, assembly operations, and applications that require high-precision positioning.

[0006] Therefore, it is necessary to invent a three-axis motion control device to solve the above problems. Content of the Utility Model
