However, this adjustment method is cumbersome and requires high skills of the debugging personnel. It also requires repeated calibration, and deviation will occur again when it is finally locked. Therefore, this method of adjusting the eccentricity cannot well guarantee the adjustment accuracy, resulting in inaccurate test data and failure to achieve the test purpose. Utility Model Content

[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0028] See also Figures 1 to 6 The utility model relates to a preferred embodiment of an eccentricity adjustment tool for an experimental shaft of a sealing rotary experimental platform.

[0029] The seal rotary test bench test shaft eccentricity adjustment tool comprises a fixed shaft 1 and a test shaft sleeve 2 , and the test shaft sleeve 2 is configured to be sleeved on the fixed shaft 1 .

[0030] Specifically, the first is the fixed shaft 1, which includes a fixed shaft body 11. The fixed shaft body 11 has an integrated eccentrically arranged positioning shaft 12 along the axial direction, and the axis center line of the fixed shaft body 11 and the axis center line of the positioning shaft 12 are arranged parallel to each other.

[0031] Generally speaking, setting the eccentricity between the fixed shaft body 11 and the positioning shaft 12 to 0-1 mm can achieve eccentricity adjustment within this range and also meet the test requirements of the concentricity test.

[0032] Preferably, in this embodiment, the eccentricity between the fixed shaft body 11 and the positioning shaft 12 is 0.5 mm.

[0033] Next is the test sleeve. The test sleeve 2 includes a sleeve body 21 having an integral eccentrically arranged positioning sleeve 22 along the axial direction. The axis of the sleeve body 21 and the axis of the positioning sleeve 22 are parallel to each other. The inner cavity of the positioning sleeve 22 has a positioning hole 23.

[0034] Generally speaking, the eccentricity between the sleeve body 21 and the positioning sleeve 22 is 0-1 mm, which can achieve eccentricity adjustment within this range and also meet the test requirements of the concentricity test.

[0035] Preferably, in this embodiment, the eccentricity between the sleeve body 21 and the positioning sleeve 22 is 0.5 mm.

[0036] In the present invention, the positioning hole 23 is a hole on the test sleeve 2 that is used to match the positioning shaft end of the fixed shaft 1, ensuring that the test sleeve 2 can be accurately installed on the fixed shaft 1. The positioning shaft end is the part on the fixed shaft that is used to match the positioning hole of the test sleeve, and has a shape and size that matches the positioning hole of the test sleeve.

[0037] Furthermore, bolt holes 24 are provided on the positioning sleeve of the test sleeve 2, and there are at least three bolt holes 24, which are evenly distributed along the circumferential direction of the positioning sleeve 22. Fastening bolts 3 are installed in the bolt holes 24 to achieve fastening between the fixed shaft 1 and the test sleeve 2, thereby preventing the entire tooling from relative movement or rotation during the test process.

[0038] Furthermore, an identification scale 4 is provided at the end of the fixed shaft body 11, and an indicator arrow 5 pointing to the identification scale 4 is provided at the position where the positioning sleeve 22 cooperates with the fixed shaft body 11, so that the current eccentricity adjustment data can be understood more intuitively, so that the eccentricity adjustment has a basis, and precise adjustment can be achieved to meet the required test requirements.

[0039] The test sleeve 2 is installed on the fixed shaft 1 to obtain the eccentric adjustment fixture that can be used in the seal rotary test bench. The specific installation process is as follows:

[0040] The test sleeve 2 is sleeved on the end of the positioning shaft 12 of the fixed shaft 1 through the positioning hole 23 of the positioning sleeve 22, and then rotated in the relative direction.

[0041] During the rotation adjustment process, observe the marking scale 4 and the indicator arrow 5. The marking scale 4 provides a precise scale to indicate the current eccentricity or adjustment position. The indicator arrow 5 points to a certain scale on the scale and moves with the rotation, thereby showing the current adjustment status and achieving precise adjustment.

[0042] After adjustment into position, use three fastening bolts 3 to fasten the test sleeve 2 onto the fixed shaft 1.

[0043] The installation and adjustment of the above-mentioned fixed shaft and test shaft sleeve are very convenient and quick. In the case of replacing the test product in the future, the test requirements can be met by simply replacing the test shaft sleeve.

[0044] The utility model avoids the defects of the prior art by using the concentric and relative eccentric methods. Concentric means relative concentricity, and eccentric means relative eccentricity. In this way, when two workpieces rotate in relative directions, the relative eccentricity can be adjusted.

[0045] The rotating shaft and sleeve are concentrically arranged without gap, so the relative eccentricity adjustment can be achieved by relative counter-rotation.

[0046] Combined with the marking scale, quantitative organic adjustment can be achieved, adjustment with reference, and finally the bolts can be tightened and the meter can be calibrated once. The operation is convenient and simple, and the skill requirements for the operator are low, which can save costs and improve efficiency.

[0047] The beneficial effects of the eccentric adjustment tooling of the test shaft of the seal rotary test bench of the utility model are:

[0048] Ability to adjust the eccentricity quantitatively to ensure the accuracy of eccentricity adjustment;

[0049] It can not only realize eccentric adjustment, but also concentric test, and can realize eccentric adjustment in various situations. Moreover, the adjustment is convenient and quick. By replacing the test sleeve, the test requirements of different test products can be met.

[0050] The tooling has a simple structure, requires low operator skills, and can achieve rapid changeover and adjustment, which can save costs and improve efficiency.

[0051] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
