Technical Field

[0001] This utility model relates to the field of testing devices, specifically to a device for testing the concentricity of the center seat of an I-beam wheel. Background Technology

[0002] When the H-beam reel is working, it is clamped between the center seats and moves in a high-speed circular motion to take in the wire. After prolonged use, problems such as vibration and poor winding may occur during the rotation of the H-beam reel. There are several reasons for this, one of which is wear and misalignment of the center seats. Currently, there is no detection device to determine whether the center seats at both ends of the H-beam reel are concentric. The center seats are connected to the center shaft, which provides rotational force to the center seats. Disassembly is a large-scale project, resulting in long downtime for the entire machine. It is necessary to determine whether the center seats are misaligned before replacing them. Summary of the Invention

[0024] refer to Figure 7 and Figure 8 As shown, this utility model provides a concentricity detection device for a center seat of an I-beam wheel, including a first sliding sleeve assembly 8 and a second sliding sleeve assembly 9. The first sliding sleeve assembly 8 can be partially fitted into the second sliding sleeve assembly 9. The first sliding sleeve assembly 8 includes a vertically arranged first flange 82 and a horizontally arranged inner cylinder 81. The inner cylinder 81 is cylindrical in shape and has a smooth first curved surface 811, which is the outer surface of the inner cylinder 81. The first flange 82 has several first screw holes 821. The number and position of the first screw holes 821 on the first flange 82 match the number and position of the first threaded holes 11 on the first center seat 1. By setting bolts 21 on the first screw holes 821 and the first threaded holes 11, the first sliding sleeve assembly 8 can be fixed on the first center seat 1. The first flange 82 has... The first abutment surface 822 is a smooth plane perpendicular to the first curved surface 811. The second sliding sleeve assembly 9 includes a vertically arranged second flange 92 and a horizontally arranged outer cylinder 91. The outer cylinder 91 is cylindrical and has a smooth second curved surface 911, which is the inner surface of the outer cylinder 91. The second flange 92 has several second screw holes 921. The number and position of the second screw holes 921 on the second flange 92 match the number and position of the second threaded holes 51 on the second center seat 5. The second sliding sleeve assembly 9 can be fixed to the second center seat 5 by setting bolts 21 on the second screw holes 921 and the second threaded holes 51. The second flange 92 has a second abutment surface 922, which is a smooth plane perpendicular to the second curved surface 911. The diameter of the cross-section where the first curved surface 811 is located is D_outer, and the diameter of the cross-section where the second curved surface 911 is located is D_inner.

[0025] Specifically, the first sliding sleeve assembly 8 is T-shaped, with the axis of the inner cylinder 81 coinciding with the axis of the first flange 82, and the first contact surface 822 being a smooth annular surface; the second sliding sleeve assembly 9 is T-shaped, with the axis of the outer cylinder 91 coinciding with the axis of the second flange 92, and the second contact surface 922 being a smooth annular surface. The outer wall of the inner cylinder 81 has a smooth curved first surface 811, and the outer wall of the outer cylinder 91 has a smooth curved second surface 911. The diameter of the cross-section containing the first curved surface 811 is D. 外 The diameter of the cross section containing the second curved surface 911 is D. 内 D 外 Slightly greater than D 内 This allows the inner cylinder 81 to fit inside the outer cylinder 91, and after assembly, there is a gap between the first curved surface 811 and the second curved surface 911, satisfying D. 内 -D 外 =8~9 mils. This allows the inner cylinder 81 to slide flexibly within the outer cylinder 91, changing the length of the inner cylinder 81 fitted onto the outer cylinder 91.

[0026] Specifically, when the first sliding sleeve assembly 8 is installed on the first center seat 1, the first abutting surface 822 and the first plane 13 can fit tightly together; when the second sliding sleeve assembly 9 is installed on the second center seat 5, the second abutting surface 922 and the second plane 53 can fit tightly together.

[0027] When using the concentricity detection device for the center seat of the I-beam wheel provided by this utility model, firstly, the inner cylinder 81 of the first sliding sleeve assembly 8 is inserted into the outer cylinder 91 of the second sliding sleeve assembly 9. Then, the first center 2 and the second center 4 at the I-beam wheel station are removed. The distance between the moving end and the fixed end is adjusted, and the first abutment surface 822 on the first sliding sleeve assembly 8 is aligned with the first plane 13 on the first center seat 1. The second abutment surface 922 on the second sliding sleeve assembly 9 is aligned with the second plane 53 on the second center seat 5. Bolts 21 are inserted into the first screw hole 821 and the second screw hole 921 respectively, and each bolt 21 is tightened evenly to ensure that the first abutment surface 822 is tightly aligned with the first plane 13, and the second abutment surface 922 is tightly aligned with the second plane 53. At this time, the first sliding sleeve assembly 8 is fixed to the first center seat 1 by the first flange 82, and the second sliding sleeve assembly 9 is fixed to the second center seat 5 by the second flange 92. That is, the first sliding sleeve assembly 8 and the first center seat 1 are assembled into a fixed end, and the second sliding sleeve assembly 9 and the second center seat 5 are assembled into a movable end. At this time, the movable end is moved horizontally relative to the fixed end. The resistance to the movement is used to determine whether the inner cylinder 81 and the outer cylinder 91 are engaged. If they are engaged, it means that the first plane 13 on the first center seat 1 and the second plane 53 on the second center seat 5 are not parallel, thus indicating that the first center seat 1 and the second center seat 5 are not concentric. If they slide smoothly, it means that the first plane 13 on the first center seat 1 and the second plane 53 on the second center seat 5 are parallel, thus indicating that the first center seat 1 and the second center seat 5 are concentric.

[0028] In some embodiments, the first screw hole 821 and the second screw hole 921 are countersunk holes to facilitate the installation of bolts 21.

[0029] In some embodiments, the length of the inner cylinder 81 is the same as the length of the outer cylinder 91, and the length of the inner cylinder 81 is 2 / 3 to 4 / 5 of the length of the I-beam wheel.

[0030] In some embodiments, the inner cylinder 81 is a hollow cylinder, which can reduce the weight of the inner cylinder 81 and facilitate assembly.

[0031] The concentricity detection device for the center seat of the I-beam wheel provided by this utility model can determine whether the center seat is concentric by measuring the resistance between the sliding of the inner cylinder 81 and the outer cylinder 91.

[0032] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
