Description
Technical Field
The utility model relates to a derailleur disassembly equipment field, concretely relates to instrument for dismantling derailleur fast.
Background
A transmission is a mechanism for changing the speed and torque from an engine, which can change the ratio of the output shaft to the input shaft, either fixed or in steps, also known as a gearbox. When the derailleur was maintained, at first the ring flange of equipment personnel department with the derailleur output shaft department was demolishd, if demolish improper can cause the damage to the spare part of ring flange and ring flange department installation, even derailleur casing, influence derailleur life, consequently need specialized tool to dismantle the derailleur.
When the three-jaw type puller is detached by using the traditional tool, the requirement on the mounting position of the output shaft is high due to the thicker fork leg, the reliability is low, and the tool is complicated to use. The efficiency is low; when the hammer is pulled out to use and is dismantled, because the location is inaccurate, there is the risk of damaging the bearing, and the safety box is low. Therefore, a new tool is needed to be developed to safely and quickly remove the transmission.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a not enough to above-mentioned problem, the utility model aims at providing a be used for dismantling derailleur fast instrument, this instrument simple structure, convenient to use uses this instrument can improve the work efficiency who dismantles the variable speed.
The utility model discloses a realize through following technical scheme: the utility model provides an instrument for dismantling derailleur fast which characterized in that, is equipped with the transmission lead screw and the dismantlement dish of hexagonal boss including the head, the intermediate position of dismantling the dish is equipped with the screw, and the transmission lead screw passes the screw and connects the dismantlement dish, still is equipped with a plurality of through-holes on the dismantlement dish, and the through-hole circumference is arranged on the dismantlement dish.
Preferably, the through holes are matched with the holes in the transmission flange plate and fixedly connected with the holes in the transmission flange plate through bolts.
The utility model has the advantages that: the tool is simple in structure and convenient to use, a worker can rapidly disassemble the speed changer by using the tool, the working efficiency is improved, and the speed changer can be disassembled by using the tool, so that the damage to the surface of the shell can be effectively prevented, and the disassembly safety is improved.

Detailed Description
In order to make the objects, technical solutions and advantageous effects of the present invention more clear, the following embodiments are combined to further explain the technical solutions of the present invention. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1 to 4, a tool for rapidly disassembling a transmission comprises a transmission screw rod 2 and a disassembly disc 3, wherein the head part of the transmission screw rod is provided with a hexagonal boss 1, a screw hole 4 is arranged in the middle of the disassembly disc 3, the transmission screw rod 2 penetrates through the screw hole 4 to be connected with the disassembly disc 3, a plurality of through holes 5 are further arranged on the disassembly disc 3, the through holes 5 are circumferentially arranged on the disassembly disc 3, and the through holes 5 are matched with holes in a transmission flange 7 and are fixedly connected with the holes in the transmission flange 7 through bolts 6.
During the dismantlement, pass screw 4 with drive screw 2 and dismantle the dish 3 and install together, dismantle dish 3 and be located drive screw 2 bottoms, then will dismantle the hole one-to-one on the dish 3 through-hole 5 and the derailleur output ring flange and utilize bolt 6 with through-hole 5 and the hole fixed connection on the ring flange, at this moment, this instrument is rotated to the handheld handle centre gripping hexagonal boss 1 of staff, dismantles the dish 3 and receives the screw drive power to drive the ring flange outwards removal this moment, accomplishes the dismantlement.
The above embodiments are only specific examples of the present invention, and are not intended to limit the present invention in any way, and those skilled in the art may modify or modify the above embodiments by using the technical content disclosed above and equivalent embodiments. However, any simple modification, equivalent change and modification made to the above embodiments by the technical entity of the present invention should fall within the protection scope of the present invention.
