Description

Technical Field

[0001] This utility model relates to the field of measuring fixtures, and in particular to a measuring fixture for measuring the circular runout of a countercurrent centrifugal washer rotor. Background Technology

[0002] For biological liquid countercurrent centrifugal elutors, the inlet and outlet of the rotor need to be coaxial and circular. The quantitative data is that the circular runout on both sides is ≤0.1mm. Existing measuring instruments are not suitable for measuring this product. Traditional measurement of the circular runout at both ends of the rotor requires two separate measurements, which is expensive and has a long measurement cycle. Summary of the Invention

[0006] The rotor has a liquid inlet on one side and a liquid outlet on the other side.

[0007] The guide rail assembly includes a linear slide rail fixed on a base, with a first slider and a second slider slidably connected on the linear slide rail;

[0008] The first measuring mechanism, fixedly mounted on the first slider, includes:

[0017] The rotor inlet of the rotor under test is inserted into the rotating drum, and the rotor outlet is inserted into the positioning bearing. When the rotor rotation rocker is rotated, the rotating shaft drives the rotating drum and the rotor to rotate synchronously through gear transmission.

Furthermore, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements.

[0034] This utility model discloses a measuring tool for the circular runout of a countercurrent centrifugal washer rotor. Please refer to [link / reference]. Figure 2 Includes: a rotor 1, with a rotor inlet 11 on one side and a rotor outlet 12 on the other side;

[0035] Please see Figure 1The guide rail assembly includes a linear slide rail 3 fixed on the base 2, and a first slider 4 and a second slider 5 slidably connected on the linear slide rail 3; the linear slide rail, in conjunction with the adjustable slider, can adapt to the detection requirements of rotors of different sizes.

[0036] Please see Figure 5 and Figure 6 The first measuring mechanism 6 is fixedly mounted on the first slider 4 and includes: an inlet clamp seat 61, which has an inlet rotor positioning clamp 62 on the side facing the second slider 5, and the top of the inlet clamp 62 has a first opening 63; a rotary drive unit, including a rotating shaft 64 passing through the inlet clamp seat 61, with a rotor rotating rocker arm 65 at one end of the rotating shaft 64 and a drive gear 66 at the other end; a rotating cylinder 68, which is mounted in the inlet rotor positioning clamp 62 through a first bearing 611, and a driven gear 69 that meshes with the drive gear 66 at the outer end of the rotating cylinder 68; and an inlet measuring dial indicator 8, which is mounted on the top of the inlet clamp seat 61, with the detection end of the inlet measuring dial indicator 8 extending into the first opening 63 to measure the rotor inlet 11.

[0037] Please see Figure 3 and Figure 4 The second measuring mechanism 7 is fixedly mounted on the second slider 5 and includes: an outlet clamp seat 71, on the side facing the first slider 4, an outlet rotor positioning clamp 72 is provided, and the top of the outlet rotor positioning clamp 72 is provided with a second opening 73; an outlet measuring dial indicator 9 is mounted on the top of the outlet clamp seat 71, and the detection end of the outlet measuring dial indicator 9 extends into the second opening 73 to measure the rotor outlet 12; and a positioning bearing 74 is installed inside the outlet rotor positioning clamp 72.

[0038] The rotor inlet 11 of the rotor to be tested is inserted into the rotating drum 68, and the rotor outlet 12 is inserted into the positioning bearing 74. When the rotor rotating rocker arm 65 is rotated, the rotating shaft 64 drives the rotating drum 68 and the rotor 1 to rotate synchronously through gear transmission. The inlet measuring dial indicator 8 and the outlet measuring dial indicator 9 measure the synchronous radial runout of the rotating rotor inlet 11 and rotor outlet 12, respectively.

[0039] The countercurrent centrifugal washer rotor circular runout measuring fixture provided in this embodiment of the invention simultaneously measures the rotor's inlet and outlet through two opposing and movable measuring mechanisms, improving measurement efficiency, ensuring real-time comparison of test data, and improving coaxiality detection accuracy. The double-support structure of the rotating drum and positioning bearing forms a stable rotation axis, avoiding measurement errors caused by rotor radial sway. The combination of gear transmission and rocker operation enables manual and precise control of the rotor speed, meeting the requirements of precision measurement. The linear slide rail with adjustable slider can adapt to the testing needs of rotors of different sizes.

[0040] Please see Figure 6 The driving gear 66 and the driven gear 69 are connected by a transmission belt 610 with a transmission ratio of 1:1. The synchronous belt drive ensures the meshing accuracy of the gears and eliminates transmission errors caused by backlash. The 1:1 transmission ratio design synchronizes the rotation speed of the drum with the operation of the rocker arm, making it easy for the operator to intuitively control the testing process. The use of flexible transmission reduces the impact of mechanical vibration on the measurement accuracy of the dial indicator.

[0041] Please see Figure 3 The inlet clamp seat 61 and the outlet clamp seat 71 are respectively equipped with a first extension seat 612 and a second extension seat 75 on their opposite sides. The first extension seat 612 and the second extension seat 75 are respectively threadedly connected to a first fixing screw 613 and a second fixing screw 76. The extension seat structure expands the mounting reference surface of the clamp, enhances the overall rigidity of the measuring mechanism, and the double fixing screw design enables multi-point positioning of the clamp seat to prevent offset during measurement. The adjustable length of the extension seat can adapt to the clamping requirements of rotors of different specifications.

[0042] The linear slide rail 3 has scales on both sides, and the first slider 4 and the second slider 5 have positioning pointers corresponding to the scales. The scales provide a precise reference for the slider position, ensuring consistent positioning during repeated measurements. The positioning pointers work in conjunction with the scales to achieve visual adjustment, with an adjustment accuracy of ±0.1mm, avoiding measurement reference offset caused by slider position deviation.

[0043] Please see Figure 1 The number of first slider 4 and second slider 5 are both two. The double slider structure forms symmetrical support, improves the movement stability of the measuring mechanism on the slide rail, distributes the load, prevents guide rail deformation caused by single slider overload, and enhances the vibration resistance of the measuring mechanism under high-speed rotation conditions;

[0044] Please see Figure 6 A second bearing 67 is installed at the connection between the rotating shaft 64 and the inlet clamp seat 61. The second bearing constitutes the axial positioning of the rotating shaft, eliminating the influence of shaft movement on gear meshing. The double bearing support structure reduces the rotational friction coefficient of the rotating shaft, extends the service life of the transmission system, improves the smoothness of the rocker operation, and ensures the measurement condition of uniform rotor rotation.

[0045] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0046] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
