Description

Technical Field

[0001] The present invention relates to the technical field related to motion platforms, and in particular to a horizontal adjustment motion mechanism, a detection device and an adjustment method. Background Art

[0002] High-precision mobile platforms are often used in modern processing and testing equipment. For example, the common three-coordinate mobile platform is a platform that can achieve precise movement in the X, Y, and Z directions.

[0003] The components of the three-coordinate precision mobile platform in the X, Y and Z directions have the same structure, including their own transmission system, guide system, drive system, digital displacement measurement system based on capacitive sensors and corresponding supporting components.

[0004] For example, a gantry machining center on the market has dual columns that can be slidably mounted on the machine base and slide along the X-axis direction. The crossbeam is mounted between the dual columns, and the processing head is slidably mounted on the crossbeam and can slide along the Y-axis direction and the Z-axis direction. Among them, the Y-axis direction is the extension direction of the crossbeam, and the Z-axis direction is the vertical direction. The crossbeam is mounted on the dual columns to provide a certain height for the movement of the processing head along the Z-axis direction. For this type of gantry machining center, when driving the processing head to move along the X-axis direction, the drive motor in the X-axis direction needs to drive the dual columns, the crossbeam, the processing head and other components to move at the same time. Due to the heavy weight of the dual columns, not only does the drive motor in the X-axis direction require a huge driving force, and the drive requirements for the drive motor are high, but it also causes the movement of the processing head along the X-axis direction, with a long response time (start and stop) and low movement accuracy, which affects the processing accuracy of the workpiece.

[0005] After massive searches, it was found that the Chinese patent announcement number is CN111468959A, which discloses a durable five-axis precision small gantry CNC machining center, which uses a three-axis slide to drive the movement of the machining head of the CNC machining center. The three-axis slide includes a crossbeam, an X-axis slide and a drive motor. The two ends of the crossbeam in the extension direction are slidably installed on the slide rails of the two supporting walls through two X-axis slides, and at least two drive motors drive the same X-axis slide at the same time.

[0006] To sum up, in the above scheme, the beam is fixed between the two X-axis slides and its position is fixed after installation. Therefore, this scheme is particularly dependent on high-speed processing of parts. If the processing accuracy of the parts is slightly poor, or the assembly process is not up to standard, and the parts are deformed, after the final product is assembled, it is often difficult to ensure that the error between the horizontal height of the beam and the standard plane is within the allowable error range, resulting in further errors in the subsequent structure, which has a serious impact.

[0007] In view of the above-mentioned defects, the designers have actively carried out research and innovation in order to create a horizontal adjustment motion mechanism, detection equipment and adjustment method to make it more valuable for industrial use. Summary of the invention

[0061] Specifically, the lower half of the optical axis bracket 711 is in the shape of a base, which is fixedly connected to the Y-axis linear drive module 4 to play a role of connection and support.

[0062] The upper part is used to install the rotating shaft 713. The upper part is in the shape of a hoop and is divided into two ring sleeves. Through holes are opened on the tops of the two ring sleeves. After the rotating shaft 713 is inserted into the installation position, it is locked by fasteners.

[0063] There are two groups of rotating shaft connection components 71, which are respectively located on both sides of the column 5. The two groups of rotating shaft connection components 71 are arranged in a straight line, and the axis direction is consistent with the Y-axis direction.

When the beam is not parallel to the standard plane, the height of the lifting end of the beam can be adjusted through the synchronous fine-tuning mechanism that can be raised and lowered, so that the parallel adjustment of the beam to the standard plane can be achieved quickly and conveniently.

[0076] In addition, the mobile drive mechanism of the Y-axis (i.e., the Y-axis linear drive module) is arranged on the side where the rotating axis connection mechanism is located, and a buffer structure component is arranged between the crossbeam and the rotating axis connection mechanism to reduce the vibration of the movement.
