Coupler dismounting device

Technical Field

The utility model belongs to the technical field of the shaft coupling is dismantled, concretely relates to shaft coupling dismounting device.

Background

The shaft coupling is the most common link part for shafting transmission in mechanical equipment, and is used for connecting two shafts (a driving shaft and a driven shaft) in different mechanisms to jointly rotate and transmit torque, and part of the shaft coupling also has the functions of buffering and damping and improving the dynamic performance of the shafting. A typical power machine is usually coupled to a working machine by means of a coupling to achieve power transmission. At present, most modern enterprises are in an equipment-based highly centralized production mode, motors and matched couplers are very common, and the number of the motors and matched couplers used in a wide and thick plate production line can reach nearly thousands. Because of the high frequency of motor maintenance, the dismouting of shaft coupling is also frequent thereupon, and current shaft coupling extracting tool is the special dismounting device of "one-to-one" more, when the shaft coupling of the face many specifications is dismantled, is difficult to reach high-efficient swift dismantlement. Therefore, the shaft coupling should be improved to be disassembled for the shaft couplings with multiple specifications.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

The utility model provides a coupler dismounting device, including first horizontal pole 1, second horizontal pole 2, the fixed jack 5 that is equipped with in 1 middle part of first horizontal pole, 1 inside hollow structure that is of first horizontal pole, 2 diameters of second horizontal pole slightly are less than 1 diameter of first horizontal pole, just in time attach 1 inner wall of first horizontal pole, guarantee 2 horizontal parts of second horizontal pole can freely be in 1 inside flexible of first horizontal pole. Be equipped with the perpendicular first axle hole 3 that corresponds on the 1 lateral wall of first horizontal pole, second horizontal pole 2 wears to establish 1 inside of first horizontal pole, be equipped with the perpendicular second axle hole 4 that corresponds on the 2 lateral walls of second horizontal pole, first horizontal pole 1 with second horizontal pole 2 passes through U type bolt 6 fastening connection, first axle hole 3 with second axle hole 4 size is the same, the diameter of U type bolt 6 slightly is less than or equal to the shaft hole diameter, makes loading and unloading that U type bolt 6 can be smooth. Two the second horizontal pole 2 stretches out first horizontal pole 1 part integration is equipped with fixed block 7, fixed block 7 articulates there is the single arm-drag 8, single arm-drag 8 deviates from 7 one end of fixed block are equipped with and draw claw 9. The inner wall of the pull claw 9 is evenly provided with anti-skidding convex points 10 which can play a role of preventing slipping when the coupler 11 is disassembled.

When the device is used for disassembling the coupler 11, because the draw arms 8 are hinged on the fixing block 7, the opening angles of the two draw arms 8 are adjusted, the coupler 11 is clamped as the standard, the draw claws 9 are used for abutting against the lower end of the coupler 11, meanwhile, the top head of the jack 5 is used for abutting against the shaft body 12, the jack 5 is operated to continue ejecting until the shaft body 12 is separated from the coupler 11, the jack 5 can be stably disassembled without impact, parts are not easy to damage, if the coupler 11 with larger or smaller size is to be disassembled, the U-shaped bolt 6 for fastening the first cross rod 1 and the second cross rod 2 is extracted from the first shaft hole 3 and the second shaft hole 4, the length to be adjusted is determined according to the requirements of a user, then the U-shaped bolt 6 is inserted, and the distance between the two draw arms 8 can be changed along with the telescopic change of the second cross rod 2.

The above description is only a preferred embodiment of the application and is illustrative of the principles of the technology employed. It will be appreciated by a person skilled in the art that the scope of the invention as referred to in the present application is not limited to the solution described above with a specific combination of features.
