Description

Technical Field

[0001] This utility model relates to the technical field of coupling testing, and in particular to a coupling dynamic balancing device. Background Technology

[0002] Couplings are mainly used to achieve transmission connections between shafts. All manufactured couplings need to undergo dynamic balancing tests. For couplings used for different purposes, the power output end has different balancing. When using coupling testing equipment, the overall balancing is mainly adjusted by installing the number of counterweights. The installation of counterweights mainly involves workers putting the counterweights on the shaft at the output end and then fixing the counterweights with the appropriate nuts. This method of installing and removing balancing blocks is not only inefficient but also labor-intensive. Therefore, this application provides a coupling dynamic balancing device that can automatically install and remove counterweights. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a coupling dynamic balancing device, comprising...

[0005] The support frame is U-shaped.

[0006] The connecting plate is movably mounted on one side wall of the support frame;

[0011] The counterweight shaft is fixedly connected to the flange shaft and faces the support shaft.

[0012] A push plate is fixedly connected to the output end of the servo motor, and the end of the push plate has a clamping groove.

[0013] The lifting plate is mounted on the side wall of the support frame above the counterweight shaft. Several electromagnet columns are mounted on the lifting plate, and a circular magnet sleeve is embedded in the counterweight shaft at the position corresponding to each electromagnet column.

[0014] Several counterweights have a positioning hole at the center. The side wall of the counterweight has a slope surface that matches the clamping groove. The push plate rotates so that the clamping groove clamps the slope surface of the counterweight. The counterweight has a constricted hole that passes through the counterweight at the position corresponding to the position of the magnet sleeve.

[0015] Several stop posts slide into the constricted hole, and the lower end of each stop post has an iron post that extends into the magnet sleeve.

[0016] Preferably, the support frame is provided with a first ball screw module and a guide rod, the guide rod slides through the first movable plate, the ball screw of the first ball screw module passes through the first movable plate and is threadedly connected to the first movable plate, and the first movable plate is fixedly connected to the connecting plate.

[0019] Preferably, the opposing surfaces of the counterweight shaft and the support shaft have a first guide post and a second guide post, respectively.

[0020] The beneficial effects of adopting the above technical solutions are:

[0021] This application uses a second movable plate to drive a push plate to move.

Then the electromagnet column is de-energized and returns to its original position. At this time, the magnetic sleeve attracts the iron column, so that the position of the counterweight block on the counterweight shaft is fixed, thereby realizing automatic disassembly and installation.

Detailed Implementation

[0026] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-3 In this first embodiment, the coupling dynamic balancing device includes...

[0028] The support frame is 80mm in size and is U-shaped.

[0029] The connecting plate 52 is movably mounted on one side wall of the support frame 80. The support frame 80 is provided with a first ball screw module 54 and a guide rod 55. The guide rod 55 slides through the first moving plate 53. The ball screw of the first ball screw module 54 passes through the first moving plate 53 and is threadedly connected to the first moving plate 53. The first moving plate 53 is fixedly connected to the connecting plate 52.

[0030] The support shaft 50 is fixedly connected to the connecting plate 52;

[0031] The second movable plate 73 is movably mounted on the other side wall of the support frame 80. The support frame 80 is provided with a second ball screw module 74. The ball screw of the second ball screw module 74 passes through the second movable plate 73 and is threadedly connected to the second movable plate 73. The second movable plate 73 and the side wall of the support frame 80 are in surface-to-surface sliding contact.

[0032] Servo motor 72 is mounted on the second movable plate 73;

[0033] A flange shaft 43 is connected to an output shaft 30, and a retaining sleeve 42 is fitted on the flange shaft 43;

[0034] The counterweight shaft 40 is fixedly connected to the flange shaft 43 and faces the support shaft 60. The opposing surfaces of the counterweight shaft 40 and the support shaft 50 have a first guide post 41 and a second guide post 51, respectively.

[0035] Push plate 70 is fixedly connected to the output end of servo motor 72, and the end of push plate 70 has a clamping groove 71;

[0036] A lifting plate 68 is mounted on the side wall of the support frame 80 above the counterweight shaft 40. The lifting plate 68 is provided with a number of electromagnet columns 67. A circular magnet sleeve 64 is embedded in the counterweight shaft 40 at the position corresponding to each electromagnet column 67. A lifting cylinder 69 is provided on the side wall of the support frame 80. The output end of the lifting cylinder 69 is fixedly connected to the lifting plate 68.

[0037] Several counterweights 60 have a positioning hole 62 at the center. The side wall of the counterweight 60 has a slope surface 61 that matches the clamping groove 71. The push plate 70 rotates so that the clamping groove 71 clamps the slope surface 61 of the counterweight 60. The counterweight 60 has a constriction hole 63 that passes through the counterweight 60 at the position corresponding to the magnet sleeve 64.

[0038] Several stop posts 66 are slidably inserted into the constricted hole 63, and the lower end of each stop post 66 has an iron post 65 that extends into the magnet sleeve 64.

[0039] This embodiment is implemented as follows:

[0040] When adding counterweights 60, the first moving plate 53 moves first, driving the support shaft 50 to move via the connecting plate 52. This causes the second guide post 51 on the support shaft 50 to contact the first guide post 41. At this point, the first moving plate 53 stops. To add n counterweights 60, the second moving plate 73 moves, driving the servo motor 72 and the push plate 70 to move. The push plate 70 moves to below the nth counterweight 60, and then the servo motor 72 drives the push plate 70 to rotate, causing the clamping groove 71 of the push plate 70 to rotate to the ramp that clamps the counterweights 60. On surface 61, the second moving plate 73 moves, causing the groove 71 of the push plate 70 to push the counterweight 60 to move, so that the counterweight 60 moves to the rightmost end of the counterweight shaft 40. Then the lifting plate 68 moves downward, causing the stop column 66 and iron column 65 on the electromagnet column 67 to move downward. The stop column 66 enters the bottom of the constriction hole 63 and is blocked, while the iron column 65 enters the magnet sleeve 64 and is attracted. Then the corresponding electromagnet column 67 is de-energized, while the other electromagnet columns 67 are not energized. Then the lifting plate 68 returns to its original position, and at this time the counterweight 60 is restricted to the counterweight shaft 40 by the iron column 65.

[0041] In this application, the attraction force of the magnet sleeve 64 to the iron column 65 is sufficient to overcome the centrifugal force of the counterweight shaft 40 rotating.

[0042] During unloading, the electromagnet column 67 attracts the stop column 66 and pulls it out. The attraction force of the electromagnet column 67 is sufficient to separate the iron column 65 from the magnet sleeve 64.

[0043] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
