Description

Technical Field

[0001] The utility model relates to the technical field of locking test equipment, in particular to a coupling matching locking degree testing device. Background Art

[0002] Common couplings generally include cross couplings, spring couplings, diaphragm couplings, plum blossom couplings, bellows couplings, parallel couplings and rigid couplings, etc. They are generally suitable for connecting two rotating bodies of different mechanisms to achieve the transmission of power and torque. They play a vital role in the mechanical field. The main purpose of the coupling is to connect two rotating devices. Even if there is an installation error between the two shafts, it can greatly reduce the uneven wear of the shafts caused by the error, thereby improving mechanical efficiency. Therefore, the coupling plays a vital role in the mechanical structure.

[0003] Currently, even after the coupling is installed and used for a long time, it is not necessarily guaranteed that the coupling can install and connect the two optical axes. If the friction between the coupling and the optical axis is insufficient, the rotation speeds of the two optical axes may be different, thereby reducing the mechanical efficiency. For this reason, this scheme provides a coupling locking degree test device. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the tightness of the connector is not high.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a coupling locking degree testing device, comprising: a coupling and two optical axes, the outer wall of the coupling is provided with a screw groove, the outer wall of the coupling is provided with a semicircular part 1 and a semicircular part 2, the outer wall of the optical axis is arranged on the inner wall of the coupling, and the outer wall of the optical axis is provided with a semi-ring part 1 and a semi-ring part 2.

[0006] A circular groove is provided at one end of the semicircular part, and a clamping rod is clamped on the inner wall of the circular groove and the screw groove. Two sleeve rings are installed on the top of the clamping rod. The inner walls of the two sleeve rings are rotatably connected with a rotating shaft. A flap is installed at one end of the rotating shaft. An arc-shaped sleeve ring is penetrated and connected on one side of the flap. An arc-shaped plate is clamped on the inner wall of the arc-shaped sleeve ring, and one side of the arc-shaped plate is installed on the outer wall of the semicircular part.

[0007] As a preferred embodiment, Velcro is installed on opposite sides of the semicircular member 1 and the semicircular member 2, and the semicircular member 1 and the semicircular member 2 are connected by the Velcro.

[0008] The technical effect of adopting the above-mentioned further scheme is: when the staff uses a coupling to install on the outer walls of the two optical axes, and then clamps the semicircular part one and the semicircular part two to the outer wall of the coupling through Velcro, and then clamps the semi-ring part one and the semi-ring part two to the outer wall of the optical axis, and then inserts the clamping rod into the screw groove and the inner wall of the circular groove (the screw groove on the outer wall of the coupling is fixed by using screws when assembling the coupling, so there will be a screw groove on the outer wall), and then in order to enable the semicircular part one and the semicircular part two to rotate synchronously with the coupling, the staff first puts the arc-shaped sleeve ring at the top of the clamping rod on the arc plate, and then flips the flap in the opposite direction of the arc-shaped sleeve ring, that is, the semicircular part one, the semicircular part two and the coupling are fixed together. When disassembly is required, only the reverse operation is needed to pry apart the semicircular part one and the semicircular part two.

[0009] As a preferred embodiment, a limiting plate is installed on the outer wall of the semi-ring component one, an L-shaped rod is installed on one side of the arc plate, and the L-shaped rod is located between the two limiting plates. Rubber rings are installed on the opposite sides of the semi-ring component one and the semi-ring component two, and the inner wall of the rubber ring is clamped on the outer wall of the optical axis. The top of the semi-ring component one is rotatably connected to a threaded rod, and a turntable is installed on the top of the threaded rod. The outer wall of the threaded rod is connected to one side of the semi-ring component two by threads, and a threaded groove is provided on one side of the semi-ring component two. A limiting rod is installed on the top of the semi-ring component one, and one side of the limiting rod is connected to one side of the semi-ring component two.

[0010] The technical effect of adopting the above further scheme is: when it is necessary to clamp the semi-annular part one and the semi-annular part two on the outer wall of the optical axis, first put the semi-annular part one and the semi-annular part two on the outer wall of the optical axis, and then manually rotate the threaded rod to move the semi-annular part one toward the semi-annular part two. In order to prevent the semi-annular part one from rotating, the limiting work can be performed by its limiting rod. In order to increase the friction between the semi-annular part one and the semi-annular part two and the outer wall of the optical axis, the friction can be increased by the rubber ring on the inner wall. If the friction between the coupling and the optical axis is insufficient, the optical axis and the coupling may not rotate synchronously. The L-shaped rod on one side of the arc plate will fit on the inner wall of the limiting plate, that is, the L-shaped rod drives the optical axis to rotate by driving the limiting plate, thereby avoiding a decrease in mechanical efficiency. At the same time, the staff can observe whether the L-shaped rod is in the center between the two limiting plates, indicating that the coupling and the optical axis are tightly clamped. If the L-shaped rod is not in the position between the two limiting plates, it indicates that there is looseness between the coupling and the optical axis.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] The utility model cooperates between the clamping rod, the flap, the arc-shaped sleeve ring, the arc-shaped plate, the L-shaped rod and the two limit plates, so that the staff can know whether the coupling is tightly clamped on the outer wall of the optical axis by observing whether the L-shaped rod is in the center position between the two limit plates. In order to reduce the rotational speed difference between the optical axis and another optical axis, the L-shaped rod is fitted on the inner walls of the two limit plates and pushes the limit plates, thereby reducing the rotational speed difference and improving the tightness of the coupling.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5The utility model provides a technical solution: a coupling locking degree testing device, comprising: a coupling 1 and two optical shafts 2, the outer wall of the coupling 1 is provided with a screw groove 3, the outer wall of the coupling 1 is provided with a semicircular part 1 4 and a semicircular part 2 5, the outer wall of the optical shaft 2 is arranged on the inner wall of the coupling 1, and the outer wall of the optical shaft 2 is provided with a semi-ring part 15 and a semi-ring part 2 16.

[0022] A circular groove 7 is provided at one end of the semicircular member 4, and a half ring of a clamping rod is clamped on the inner walls of the circular groove 7 and the screw groove 3. Two sleeve rings 9 are installed on the top of the half ring of the clamping rod. The inner walls of the two sleeve rings 9 are rotatably connected with a rotating shaft 10. A flap 11 is installed at one end of the rotating shaft 10. An arc-shaped sleeve ring 12 is penetrated and connected on one side of the flap 11. An arc-shaped plate 13 is clamped on the inner wall of the arc-shaped sleeve ring 12, and one side of the arc-shaped plate 13 is installed on the outer wall of the semicircular member 4.

[0023] like Figure 1-5 As shown, Velcro 6 is installed on the opposite side of the semicircular member 1 4 and the semicircular member 2 5 , and the semicircular member 1 4 and the semicircular member 2 5 are connected by the Velcro 6 .

[0024] When the staff installs the coupling 1 on the outer walls of the two optical axes 2, they then clamp the semicircular parts 1 4 and the semicircular parts 2 5 to the outer wall of the coupling 1 through the Velcro 6, and then clamp the semi-ring parts 1 15 and the semi-ring parts 2 16 to the outer wall of the optical axis 2, and then insert the clamping rod semi-ring into the screw groove 3 and the inner wall of the circular groove 7 (the screw groove 3 on the outer wall of the coupling 1 is fixed by screws when assembling the coupling 1, so there will be screw grooves 3 on the outer wall), and then in order to enable the semicircular parts 1 4 and the semicircular parts 2 5 to rotate synchronously with the coupling 1, the staff first puts the arc-shaped sleeve ring 12 at the top of the clamping rod semi-ring on the arc-shaped plate 13, and then flips the flap 11 in the opposite direction of the arc-shaped sleeve ring 12, that is, the semicircular parts 1 4, the semicircular parts 2 5 and the coupling 1 are fixed together. When disassembly is required, only the reverse operation is required to pry apart the semicircular parts 1 4 and the semicircular parts 2 5.

[0025] like Figure 1-5 As shown, a limit plate 22 is installed on the outer wall of the semi-ring member 15, an L-shaped rod 14 is installed on one side of the arc plate 13, and the L-shaped rod 14 is located between the two limit plates 22. A rubber ring 17 is installed on the opposite side of the semi-ring member 15 and the semi-ring member 2 16, and the inner wall of the rubber ring 17 is clamped on the outer wall of the optical axis 2. The top of the semi-ring member 15 is rotatably connected to a threaded rod 20, and a turntable 21 is installed on the top of the threaded rod 20. The outer wall of the threaded rod 20 is connected to one side of the semi-ring member 2 16 through a thread, and a thread groove 19 is provided on one side of the semi-ring member 2 16. A limit rod 18 is installed on the top of the semi-ring member 15, and one side of the limit rod 18 is connected to one side of the semi-ring member 2 16 through.

[0026] When it is necessary to clamp the semi-ring part 15 and the semi-ring part 2 16 on the outer wall of the optical axis 2, first put the semi-ring part 15 and the semi-ring part 2 16 on the outer wall of the optical axis 2, and then manually rotate the threaded rod 20 to move the semi-ring part 15 toward the semi-ring part 2 16. In order to prevent the semi-ring part 15 from rotating, the limiting rod 18 can be used to limit the position. In order to increase the friction between the semi-ring part 15 and the semi-ring part 2 16 and the outer wall of the optical axis 2, the friction can be increased by the rubber ring 17 on the inner wall. If the friction between the coupling 1 and the optical axis 2 Insufficient force may cause the optical axis 2 and the coupling 1 to be unable to rotate synchronously. The L-shaped rod 14 on one side of the arc plate 13 will fit against the inner wall of the limit plate 22, that is, the L-shaped rod 14 drives the limit plate 22 to rotate, thereby avoiding a decrease in mechanical efficiency. At the same time, the staff can observe whether the L-shaped rod 14 is in the center between the two limit plates 22, indicating that the coupling 1 and the optical axis 2 are tightly connected. If the L-shaped rod 14 is not in the position between the two limit plates 22, it indicates that there is looseness between the coupling 1 and the optical axis 2.

[0027] Working principle: When the staff installs the coupling 1 on the outer wall of the two optical axes 2, then clamps the semicircular part 1 4 and the semicircular part 2 5 on the outer wall of the coupling 1 through the Velcro 6, and then clamps the semi-ring part 15 and the semi-ring part 2 16 on the outer wall of the optical axis 2, and then manually rotates the threaded rod 20 to move the semi-ring part 15 toward the semi-ring part 2 16. In order to prevent the semi-ring part 15 from rotating, the limiting rod 18 can be used to limit the position. In order to increase the friction between the semi-ring part 15 and the semi-ring part 2 16 and the outer wall of the optical axis 2, the limiting rod 18 can be used to limit the position of the semi-ring part 15. The rubber ring 17 on its inner wall can increase its friction, and then the half ring of the clamping rod is inserted into the screw groove 3 and the inner wall of the circular groove 7. Then, in order to enable the semicircular part 1 4 and the semicircular part 2 5 to rotate synchronously with the coupling 1, the staff first puts the arc-shaped sleeve ring 12 at the top of the clamping rod 8 on the arc-shaped plate 13, and then flips the flap 11 in the opposite direction of the arc-shaped sleeve ring 12, that is, the semicircular part 1 4, the semicircular part 2 5 and the coupling 1 are fixed together. When disassembly is required, only the reverse operation is needed to pry apart the semicircular part 1 4 and the semicircular part 2 5.
