Description

Technical Field

[0001] The invention relates to the technical field of shaft system rotation accuracy measurement, and in particular to a stable and adjustable hollow shaft system rotation error detection device. Background Art

[0002] The detection of the rotation error of the hollow shaft system is an important measure to directly grasp the actual rotation accuracy of the shaft system. At present, the patent with the publication number "CN 106595543 A" discloses a rotation accuracy measurement device for the inner support shaft system connected to the hollow shaft system. The device uses the friction force to connect the measured hollow shaft system by squeezing the outer wedge sleeve through the inner wedge sleeve thread, and adjusts the uniformly distributed hexagon socket screws on the leveling bracket to make the plane mirror reach the optimal position, and uses a photoelectric autocollimator to measure the rotation error of the shaft system.

[0003] At present, the shortcomings and deficiencies of this internal support shaft system rotation accuracy measurement device are: a) It is inconvenient to adjust the tilt of the plane mirror: For a small hollow shaft system structure, the actual shaft system rotation error measurement device and the size of the plane mirror should be of appropriate size. For a relatively small rotation error detection device, it is found through actual operation that since the adjustment of the plane mirror tilt adopts the direct adjustment method of evenly distributed hexagon socket screws, there is a coupling phenomenon in the adjustment process, and it is difficult to control the tilt of the plane mirror; b) There are limitations in the applicable shaft system: The above patent adopts friction to connect with the shaft system, which is only suitable for the detection of shaft systems with fixed inner diameter or similar inner diameter; c) There are limitations in the application scenarios: For a two-dimensional shaft system, in addition to the rotation error of each shaft system, the verticality of the two shaft systems is also an important detection indicator. The structure of the above patent does not have the conditions for the verticality detection of a two-dimensional shaft system.

[0004] Based on the above technical problems, technicians in this field urgently need to develop a hollow shaft rotation error detection device that has high efficiency in mirror tilt adjustment, convenient overall assembly and disassembly, and a wide range of application scenarios, stable and easy to adjust. Summary of the invention

[0015] Furthermore, an auxiliary claw is provided on the edge of the quick-release mounting plate, which can cooperate with the auxiliary claw groove in the quick-release mounting seat to achieve installation and removal of the quick-release mounting seat and the quick-release mounting plate.

[0044] A quick-release mounting plate 5 is mounted on the end of the quick-release mounting seat 4 away from the tilt adjustment mechanism 3 , and a plurality of screw mounting holes are formed at the bottom of the quick-release mounting plate 5 for connecting with the shaft body in the hollow shaft system.

[0045] As a further introduction to this embodiment, an auxiliary claw 6 is provided at the edge of the quick-release mounting plate 5, which can cooperate with the auxiliary claw groove in the quick-release mounting seat 4 to realize the installation and removal of the quick-release mounting seat 4 and the quick-release mounting plate 5.

[0046] As a further introduction to this embodiment, the reflector seat 2 includes a mounting plate 203; and

[0047] The first ball head auxiliary mounting seat 201 and the second ball head auxiliary mounting seat 202 are used in combination, and the tilt adjustment mechanism 3 is installed in the mounting plate 203 through the cooperation of the first ball head auxiliary mounting seat 201 and the second ball head auxiliary mounting seat 202 .

[0048] As a further introduction to this embodiment, the tilt adjustment mechanism 3 is provided with four, and the tilt adjustment mechanism 3 includes an adjustment bracket 302; and

[0049] A ball head pair 301 mounted on the adjusting bracket 302, wherein one end of the ball head pair 301 away from the adjusting bracket 302 is mounted on the reflector seat 2;

[0050] An adjusting bolt 303 disposed in the adjusting bracket 302 drives the ball head pair 301 to move so as to adjust the tilt angle of the double-sided reflector 1;

[0051] The tilt adjustment mechanism 3 further includes a plurality of mounting screws 304 , and is connected to the quick-release mounting seat 4 via the mounting screws 304 .

[0052] As a preferred technical solution of this embodiment, the double-sided reflector 1 is bonded to the reflector seat 2 by epoxy adhesive.

[0053] The specific implementation steps of the hollow shaft rotation error detection are as follows:

[0054] 1) Connect the quick-release mounting plate 5 to the shaft body in the hollow shaft system through the corresponding threaded mounting holes. For the hollow shaft system with inappropriate mounting holes, an adapter device can be installed;

[0055] 2) Adjust the overall structure composed of the double-sided reflector 1, the plane mirror mounting seat 2, the tilt adjustment mechanism 3 and the quick-release mounting seat 4 to a suitable installation position, align the vacant part of the quick-release mounting seat 4 with the claw position of the quick-release mounting plate 5, and axially move the overall structure composed of the double-sided reflector 1, the plane mirror mounting seat 2, the tilt adjustment mechanism 3 and the quick-release mounting seat 4 to the quick-release mounting plate 5 to reach the axial limit position; rotate around the central axis of the overall structure composed of the double-sided reflector 1, the plane mirror mounting seat 2, the tilt adjustment mechanism 3 and the quick-release mounting seat 4 until the limit position is reached, at which time the claw in the quick-release mounting plate 5 cooperates with the groove in the quick-release mounting seat 4, and the auxiliary claw 6 in the quick-release mounting plate 5 cooperates with the auxiliary claw groove in the quick-release mounting seat 4, thereby completing the entire installation process of the hollow shaft system rotation error detection device;

For the case where the two-dimensional shaft system needs to additionally measure the verticality error of the shaft system, because the front and rear surfaces of the double-sided reflector 1 are both reflective surfaces, the verticality of the shaft system can be calculated through the measurement results of the front and rear reflective surfaces of the double-sided reflector 1;

[0057] 4) After the detection is completed, the auxiliary claw 6 can be loosened, and the overall structure composed of the double-sided reflector 1, the plane mirror mounting seat 2, the tilt adjustment mechanism 3 and the quick-release mounting seat 4 can be unscrewed from the quick-release mounting plate 5. The disassembly process can be completed by removing the quick-release mounting plate 5. The overall structure composed of the double-sided reflector 1, the plane mirror mounting seat 2, the tilt adjustment mechanism 3 and the quick-release mounting seat 4 can be repeatedly used after being installed once.

[0058] In the above technical solution, the present invention provides a stable and easily adjustable hollow shaft rotation error detection device, which has the following beneficial effects:

At the same time, the overall support stability is high, and the tilt state of the reflector remains unchanged for a long time;
