Therefore, according to the structural characteristics of the motor and the crank, the motor crank dismounting device is specially designed and manufactured, and is convenient to dismount the motor crank.
Disclosure of Invention
In order to overcome the defects in the prior art, the utility model provides a motor crank dismounting device, so that the problems that most of existing tools for dismounting motor cranks and the like in the market in the background art are standard tools such as two claws or three claws and the like, are not suitable for dismounting the crank structure, and have no supporting points. Therefore, according to the structural characteristics of the motor and the crank, the motor crank dismounting device is specially designed and manufactured, and is convenient for the motor crank dismounting problem.
The utility model provides the following technical scheme: the utility model provides a be used for dismantling motor crank device, includes support and motor, motor crank has been cup jointed on the top of motor, the support sets up on motor crank, the support is a U-shaped metal casting, the top of support is provided with pushes down the mechanism, and pushes down the end of mechanism and pass the support top and extend to inside the support, the both sides of support all are provided with stop gear for with motor crank block.
Further, the collection mechanism comprises a box body, a liquid inlet is formed in the box body, the pressing mechanism can be arranged as a threaded rod, and a threaded hole matched with the threaded rod is formed in the top end of the support.
Further, the limiting mechanism comprises a nut and a bolt, through holes are formed in two sides of the support, the two groups of through holes are respectively provided with a bolt, and the two ends of the bolt are respectively provided with an external thread and are in threaded connection with the nut.
Further, the top end of the threaded rod can be fixedly connected with a handle, one end of the handle is meshed with the top end of the pushing mechanism, and the top end of the other end of the handle is vertically and rotatably connected with the handle.
Further, a buffer pad can be wrapped in the middle of the bolt.
The utility model has the technical effects and advantages that:
1. according to the utility model, through the U-shaped bracket, through holes are formed in two sides of the bracket, bolts penetrate through the through holes and are fixed by the bolts and are inserted into the crank, when the top surface of the lower pressing mechanism props against the motor shaft, the bolts in the lower pressing mechanism are rotated clockwise by force, so that the bolts are downward, and the bracket drives the crank to move upward, so that the separation effect of the crank and the motor shaft is achieved.
2. According to the utility model, the sponge cushion is wrapped in the middle of the bolt, so that the pressure on the surface of the crank in the process of taking out the crank is reduced, and the deformation of the crank caused by directly contacting the bolt with the crank is avoided.

Detailed Description
An embodiment of the present utility model provides:
referring to fig. 1-3, a motor crank device for disassembling comprises a bracket 2 and a motor 6, wherein the top end of the motor 6 is sleeved with a motor crank 5, the bracket 2 is arranged on the motor crank 5, the bracket 2 is a U-shaped metal casting, the top end of the bracket 2 is provided with a pressing mechanism 1, the tail end of the pressing mechanism 1 penetrates through the top end of the bracket 2 and extends into the bracket 2, both sides of the bracket 2 are provided with limiting mechanisms for being clamped with the motor crank 5, the pressing mechanism 1 can be provided with a threaded rod, the top end of the bracket 2 is provided with a threaded hole matched with the threaded rod, when the top surface of the pressing mechanism 1 props against a motor shaft, a bolt in the pressing mechanism 1 is rotated clockwise by force, so that the bolt moves downwards, and the bracket 2 drives the crank 5 to move upwards, thereby achieving the separation effect of the crank 5 and the motor shaft.
Further, stop gear includes nut 3 and bolt 4, and the through-hole has all been seted up to the both sides of support 2, and the through-hole is two sets of, has all inserted bolt 4 in the through-hole, and the both ends of bolt 4 all are provided with external screw thread and threaded connection have nut 3, and stop gear passes through bolt 4 and nut 3 to be constituteed, can use the part of obsoleting in the factory, and the cost is low easily to change, further reduces the cost of this device.
