[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] This utility model provides, for example Figure 1-4 Shown: Example

[0035] A spindle rotation error analysis device, comprising:

[0036] Base 1;

[0037] Fixing bracket 2 is set on top of base 1;

[0038] Test component 3 is set in the middle of the fixed frame 2 and is used to acquire spindle rotation error data;

[0039] Support plate 4 is fixedly connected to the top of base 1 and is used to support the fixing frame 2.

[0040] Positioning component 5 is located at the top of the base 1 and is used to fix the position of the fixing bracket 2.

[0041] It should be noted that the base 1 has multiple through holes. When it is necessary to fix the base 1 in position, it can be fixed directly with bolts or by pressing it into position. The mounting bracket 2 is used to fix the position of the test component 3 and to detect the spindle rotation error through the test component 3, and the test results are transmitted to the computer for analysis. There are at least two support plates 4. When it is necessary to fix the mounting bracket 2 to the base 1, the support plates 4 support the mounting bracket 2 to prevent it from falling during installation, thus protecting the test component 3 on the mounting bracket 2.

[0042] Specifically, the test component 3 includes a capacitive displacement sensor 301 that is inserted into the middle of the fixture 2, and the output end of the capacitive displacement sensor 301 is electrically connected to a cable 302.

[0043] It should be noted that the test components 3, base 1 and mounting bracket 2 are Spindlecheck spindle rotation error detectors. In use, the spindle rotation error data is detected by capacitive displacement sensor 301 and then transmitted to the main unit via cable 302.

[0044] Specifically, positioning component 5 includes:

[0045] The limiting groove 504 is formed at the top of the base 1;

[0046] Limiting rod 503 is fixedly connected to the bottom end of the fixing frame 2, and the limiting rod 503 is inserted into the inside of the limiting groove 504;

[0047] The locking element is located on one side of the fixing frame 2.

[0048] It should be noted that the limiting rod 503 is adapted to the limiting groove 504. When it is necessary to fix the position of the fixing frame 2, the limiting rod 503 at the bottom of the fixing frame 2 is inserted into the limiting groove 504, and the limiting groove 504 is used to limit the position of the limiting rod 503 and the fixing frame 2, thereby limiting the movement direction of the fixing frame 2.

[0049] Specifically, the locking components include:

[0050] Positioning groove 502 is formed on one side of the fixing frame 2;

[0051] Positioning plate 501 is inserted into the interior of positioning groove 502, and a rotating part 6 for rotating positioning plate 501 is provided on one side of positioning plate 501.

[0052] It should be noted that the positioning groove 502 is adapted to the positioning plate 501, so that the positioning plate 501 can be inserted into the interior of the positioning groove 502. When it is necessary to fix the position of the fixing frame 2, the positioning plate 501 is used to restrict the position of the fixing frame 2, thereby fixing the position of the fixing frame 2 by the positioning component 5. Example

[0053] Rotating part 6 is used in the spindle rotation error analysis device in Embodiment 1;

[0054] Specifically, the rotating part 6 includes:

[0055] Rotating rod 602 is fixedly connected to one side of positioning plate 501;

[0056] Torque 601 is fixedly connected to the top of rotating rod 602 and is used to rotate rotating rod 602.

[0057] Rotating ring 605 is sleeved on the middle part of rotating rod 602;

[0058] Torsion spring 606 is located at the bottom of rotating ring 605, and rotating rod 602 is inserted and connected to the middle of torsion spring 606.

[0059] It should be noted that the rotating ring 605 is fixedly sleeved in the middle of the rotating rod 602, and the torsion spring 606 is set at the bottom of the rotating ring 605. When the rotating rod 602 is rotated, the rotating rod 602 drives the rotating ring 605 to rotate, and the rotating ring 605 drives the torsion spring 606 to deform. When the rotation of the rotating rod 602 is released, the torsion spring 606 restores its deformation and drives the rotating ring 605 and the rotating rod 602 to reset.

[0060] Specifically, a fixing block 603 is fixedly connected to the top of the base 1. A rotating groove 604 is provided on one side of the fixing block 603. A rotating rod 602 is inserted into the inner wall of the top of the rotating groove 604. A limiting ring 608 is sleeved on the bottom of the rotating rod 602. A limiting plate 607 for pressing the limiting ring 608 is provided on the top of the limiting ring 608. The rotating rod 602 is inserted into the middle of the limiting plate 607. The limiting plate 607 is fixedly connected to the inner wall of one side of the rotating groove 604.

[0061] It should be noted that the fixed block 603 is fixedly connected to the top of the base 1, and the limiting plate 607 is fixedly inserted into the inside of the rotating groove 604. A hole adapted to the rotating rod 602 is opened in the middle of the rotating groove 604, so that the rotating rod 602 can pass through the hole and pass through the limiting plate 607. The limiting ring 608 is fixedly sleeved on the bottom of the rotating rod 602, and the limiting plate 607 restricts the limiting ring 608, and the movement of the rotating rod 602 is restricted by the limiting ring 608 that restricts movement.

[0062] Furthermore, when it is necessary to fix the position of the fixing frame 2, first rotate the torsion cap 601. The torsion cap 601 drives the rotating rod 602 and the rotating ring 605 to rotate. The rotating ring 605 pulls the torsion spring 606, causing it to deform. The rotating rod 602 drives the positioning plate 501 to rotate into the interior of the rotating groove 604. Then, move the fixing frame 2 to the top of the base 1 and insert the limiting rod 503 at the bottom of the base 1 into the interior of the limiting groove 504 on the base 1. When the positioning plate 501 is aligned with the positioning groove 502, release the rotation of the torsion cap 601. At this time, the torsion spring 606 returns to its deformation. The torsion spring 606 drives the rotating ring 605 and the rotating rod 602 to rotate. The rotating rod 602 drives the positioning plate 501 to move into the interior of the positioning groove 502.

[0063] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
