Technical Field
[0001] This utility model relates to the field of four-axis turntable calibration technology, specifically to a four-axis turntable calibration structure. Background Technology
[0002] A four-axis rotary table is a type of rotary worktable on CNC machine tools or machining centers. It is mainly used to achieve multi-angle positioning and continuous machining of workpieces, expanding the machining capabilities of machine tools and enabling them to complete more complex polyhedral or curved surface machining.
[0003] The existing four-axis rotary tables are very difficult to calibrate. Traditional calibration methods often lack effective positioning and fine-tuning mechanisms, making it difficult for calibrators to accurately adjust the rotary table to the ideal position. On the other hand, due to the inability to guarantee calibration accuracy, the rotary table is prone to positional deviations during operation, which in turn affects the machining accuracy and product quality.

On the other hand, due to the inability to guarantee adjustment accuracy, the rotary table is prone to positional deviations during operation, which in turn affects the processing accuracy and product quality.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a four-axis rotary table adjustment structure, including a machine tool table, a base plate on the top of the machine tool table, the machine tool table and the base plate being fixedly connected by bolts, a sliding groove on one side of the base plate, a slider inside the sliding groove, a mounting plate fixedly mounted on the top of the slider, a rotary table body on the top of the mounting plate, two adjustment components on the top of the mounting plate, and a positioning component on the top of the base plate;
[0006] The adjustment assembly includes an adjustment block that passes through the turntable body and is fixedly connected to it. The top of the adjustment block has two second screw holes, and an internal hexagon screw is rotatably connected inside the second screw holes. The internal hexagon screw is connected to the mounting plate by a thread.

[0025] The adjustment assembly includes an adjustment block 12, which passes through the turntable body 5 and is fixedly connected to the turntable body 5. The top of the adjustment block 12 has two second screw holes 13, and an internal hexagon screw 10 is rotatably connected inside the second screw holes 13. The internal hexagon screw 10 is threadedly connected to the mounting plate 3, and the slider 14 slides inside the slide groove 6.
[0026] In this embodiment, the turntable body 5 is installed on the top of the mounting plate 3, and the adjusting block 12 is fixed to the mounting plate 3 by the internal hexagon screw 10. By rotating and adjusting the position of the internal hexagon screw 10, the position of the adjusting block 12 can be adjusted, thereby adjusting the position of the turntable body 5, ensuring that it can be adjusted to the desired position, improving the accuracy of the machine tool, making it more conducive to the debugging of the machine tool, and facilitating the position adjustment by the debugging personnel.
[0027] To achieve the positioning purpose, the device adopts the following technical solution: The mounting plate 3 has slots on both sides. The positioning component includes a side plate 4, with a side groove 15 inside the side plate 4. A retaining plate 11 is provided inside the side groove 15.

Rotate the knob 7, and the knob 7 drives the threaded rod 8 to rotate. The threaded rod 8 drives the clamping plate 11 to move. The clamping plate 11 moves out of the side groove 15 and into the groove, thereby limiting and fixing the position of the mounting plate 3. By adjusting the position of the clamping plates 11 on both sides, the position of the mounting plate 3 on the base plate 2 can be adjusted. Then, install the turntable body 5 on the top of the mounting plate 3, and fix the adjusting block 12 to the mounting plate 3 with the internal hexagon screw 10. By rotating and adjusting the position of the internal hexagon screw 10, the position of the adjusting block 12 can be adjusted, thereby adjusting the position of the turntable body 5 to ensure that it can be adjusted to the desired position, improving the accuracy of the machine tool, making it more conducive to the debugging of the machine tool, and facilitating the position adjustment of the debugging personnel.
