During the use, be connected this extracting tool with the pistol drill to the cover is established in special-shaped nut top, starts the pistol drill and can realize the installation and demolish of special-shaped nut, and overall design is simple ingenious, has improved the dismouting efficiency of special-shaped nut, has shortened maintenance cycle, has better practicality.
Description
Technical Field
The utility model belongs to the equipment maintenance application, concretely relates to dysmorphism nut assembly and disassembly tools.
Background
The speed reducer, also known as a speed reducer, is an independent component consisting of gear transmission, worm transmission and gear-worm transmission which are enclosed in a rigid shell, is often used as a speed reduction transmission device between a prime mover and a working machine, is used for matching rotating speed and transmitting torque between the prime mover and the working machine, and is widely applied to modern machinery.
The speed reducer as a speed regulation transmission device is provided with a plurality of adjusting nuts with different functions, wherein some adjusting nuts are used for adjusting the pretightening force of a spring, some adjusting nuts are used for adjusting the stroke of a valve, and other adjusting nuts are used for adjusting the displacement of a certain component. The nuts are not conventional nuts, belong to special-shaped nuts and cannot be disassembled and assembled by using conventional wrenches. In the routine maintenance process, the special-shaped nut is disassembled and assembled, common tools such as a steel bar and a punch are usually used, the working efficiency is low, the thread and the component bottom buckle of the special-shaped nut are easily damaged, and the fastening torque is difficult to accurately control.
SUMMERY OF THE UTILITY MODEL
To the technical problem, the utility model provides a dysmorphism nut assembly and disassembly tools to solve the problem of this type of dysmorphism nut dismouting difficulty.
The utility model adopts the following technical scheme:
a special-shaped nut dismounting tool comprises a dismounting disc, wherein a plurality of first convex teeth are uniformly distributed at the peripheral edge of the dismounting disc, the middle part of the dismounting disc is connected with a guide sleeve, and the guide sleeve and the first convex teeth are positioned on the same side of the dismounting disc; the middle part of dismouting dish still runs through and is equipped with external square hole, and this external square hole is coaxial with the uide bushing.
The utility model discloses following beneficial effect has:
the guide sleeve on the dismounting tool can ensure that the dismounting tool is combined with the special-shaped nut quickly and accurately, and can prevent the dismounting tool from falling off to cause potential safety hazards in use. When the special-shaped nut is installed, the guide sleeve of the disassembling tool is used for combining a plurality of convex teeth on the special-shaped nut with the groove on the special-shaped nut, and the external square hole at the rear end is connected with the torque tool, so that the special-shaped nut can be quickly installed and fastened to a standard torque; when the special-shaped nut is disassembled, the plurality of convex teeth on the special-shaped nut are combined with the groove on the special-shaped nut by means of the guide sleeve of the disassembling tool, the external square hole at the rear end is connected with the disassembling tool, and the special-shaped nut can be disassembled quickly.

Detailed Description
The invention is further explained with reference to the drawings and the detailed description.
As shown in fig. 1 and 2, the special-shaped nut dismounting tool comprises a circular dismounting disc 1, wherein four first convex teeth 2 are distributed on the disc surface of the dismounting disc 1 in an array manner, and the four first convex teeth 2 are positioned at the peripheral edge of the dismounting disc 1; an external square hole 4 is formed in the assembling disc 1 in a penetrating mode, and the external square hole 4 is located in the center of the array of the first convex teeth 2; one side of the first convex tooth 2 on the dismounting disc 1 is also connected with a guide sleeve 3, and the guide sleeve 3 is coaxial with the external square hole 4.
A special-shaped nut commonly used on the speed reducer is shown in fig. 3 and 4, eight second convex teeth 6 are arranged on the upper end surface of the special-shaped nut 5, and a cavity is formed by inwards sinking the lower end surface; the outer peripheral surface of the special-shaped nut 5 is also provided with a plurality of circles of external threads.
The working process of the utility model is as follows: when the special-shaped nut 5 is installed, the four first convex teeth 2 are clamped into the grooves between two adjacent second convex teeth 6 on the special-shaped nut 5 by means of the guide sleeve 3 on the dismounting disc 1, and then the external square hole 4 is connected with a torque tool (such as a pistol drill or a torque wrench), so that the quick installation and standard torque fastening of the special-shaped nut 5 can be realized; when the special-shaped nut 5 is dismounted, the four first convex teeth 2 on the dismounting disc 1 are clamped into the grooves between two adjacent second convex teeth 6 on the special-shaped nut 5 by means of the guide sleeve 3 on the dismounting disc 1, and then the external square hole 4 is connected with a dismounting tool (such as a pistol drill), so that the special-shaped nut can be dismounted quickly.
