Description
Technical Field
The utility model belongs to the technical field of machining, especially, relate to a coupling pin dismounting device.
Background
In railway transportation, a part of torque transmission of locomotive equipment adopts a coupling form, and in maintenance work, the coupling is often required to be separated, so that at present, two methods are mainly adopted, namely, a certain half coupling of the coupling is fixed, and the other half coupling is pulled by traction equipment to separate the two half couplings, so that the method is limited by fields and equipment, cannot be implemented under many conditions, is time-consuming, labor-consuming and low in efficiency; secondly, one end face of the coupling pin is strongly hammered by a hammering tool to withdraw the pin and separate the two half couplings, most of the disassembled pins are deformed and scrapped and cannot be used for the second time, and other parts are loosened due to hammering vibration and have adverse effects on the working environment.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem that exists, the utility model provides a shaft coupling pin dismounting device, this shaft coupling pin dismounting device simple structure, it is convenient to use, can dismantle the shaft coupling pin fast, has protected operational environment, has improved work efficiency, has practiced thrift cost of maintenance.
In order to achieve the above object, the present invention adopts the following technical solutions, including:
mirror symmetry's left socle, right branch frame, the upper portion of left socle, the upper portion suit uide bushing of right branch frame, the middle part of left socle is equipped with the levogyration internal thread, the middle part of right branch frame is equipped with the dextrorotation internal thread, the levogyration internal thread cooperatees with the levogyration external screw thread of lead screw, the dextrorotation internal thread cooperatees with the dextrorotation external screw thread of lead screw, the middle part fixed connection nut of lead screw, removable boss is connected to the lower extreme of left socle, removable concave station is connected to the lower extreme of right branch frame.
The boss comprises a boss body and a boss pin shaft connected with the boss body, the lower end of the left support is connected with a replaceable boss, and the boss pin shaft is embedded into a through hole in the lower end of the left support.
The concave station comprises a concave station body and a concave station pin shaft connected with the concave station body, the lower end of the right support is connected with the replaceable concave station, and the concave station pin shaft is embedded into a through hole in the lower end of the right support.
The left support, the right support, the screw rod, the boss and the concave platform are all made of steel.
The utility model discloses simple structure, it is convenient to use, can dismantle the shaft coupling pin fast, has protected operational environment, has improved work efficiency, has practiced thrift cost of maintenance.

Detailed Description
The present invention will be described in further detail below with reference to the attached drawings so as to enable those skilled in the art to more clearly understand the invention.
As shown in fig. 1, the utility model discloses a mirror symmetry's left socle 1, right branch frame 2, the upper portion of left socle, the upper portion suit uide bushing 3 of right branch frame, the middle part of left socle is equipped with the left-handed internal thread, the middle part of right branch frame is equipped with the dextrorotation internal thread, the levorotation internal thread cooperatees with the levogyration external thread of lead screw 4, the dextrorotation internal thread cooperatees with the dextrorotation external thread of lead screw, the middle part fixed connection nut 5 of lead screw, removable boss 6 is connected to the lower extreme of left socle, removable concave station 7 is connected to the lower extreme of right branch frame.
As shown in fig. 2 and 3, the boss includes a boss body 6-1 and a boss pin shaft 6-2 connected to the boss body, and the lower end of the left bracket is connected to the replaceable boss, which is a through hole for embedding the boss pin shaft into the lower end of the left bracket.
As shown in fig. 4 and 5, the recessed table includes a recessed table body 7-1 and a recessed table pin 7-2 connected to the recessed table body, and the lower end of the right bracket is connected to the replaceable recessed table, which is a through hole for inserting the recessed table pin into the lower end of the right bracket.
The left support, the right support, the screw rod, the boss and the concave platform are all made of steel.
When the device is used, the small nut at the left end of the pin 9 is screwed off, so that the boss body is attached to the left end face of the pin, the concave table body is attached to the right side face of the right half coupling 8, the right end of the pin is placed in the groove of the concave table body, the nut in the middle of the lead screw is rotated, the left support and the right support move in opposite directions, and the pin is ejected out of the left half coupling 10 by the boss body due to the resultant force action of the left support and the right support, so that the dismounting work is completed.
The utility model relates to a shaft coupling pin dismounting device, this shaft coupling pin dismounting device simple structure, it is convenient to use, can be quick dismantle the shaft coupling pin, protected operational environment, improved work efficiency, practiced thrift cost of maintenance.
