Description

Sleeve tool for disassembling and assembling butterfly nut

Technical Field

The utility model relates to an automobile assembling field, concretely relates to sleeve instrument of dismouting butterfly nut.

Background

At present can use butterfly nut frequently in the automobile assembling process, wherein light calorie of battery just carries out the installation of protecting cover through butterfly nut, and the protecting cover can effectively protect the battery pencil, prevents the erosion of dust and rainwater, and consequently butterfly nut's installation fastening is especially important. However, since the wing nut is composed of a circular truncated cone with a threaded hole and two side lugs distributed along the diameter direction, the wing nut cannot be fastened or disassembled by using a daily pneumatic or electric tool, and can only be manually disassembled. The manual disassembly and assembly of the butterfly nut has corresponding defects, firstly, because the manual fastening torque is smaller and the locking force is smaller, the nut can attend the loosening condition in the use process of a vehicle. Secondly, the butterfly nut is frequently disassembled and assembled manually, the labor intensity of workers is high, and meanwhile, operation of narrow parts is inconvenient, so that the overall assembly efficiency is low.

SUMMERY OF THE UTILITY MODEL

To above problem, the utility model provides a fastening locking force requirement when satisfying the assembly of butterfly nut can be satisfied, staff intensity of labour is reduced simultaneously, the operation convenience is improved, the sleeve instrument of dismouting butterfly nut of automobile assembling overall efficiency is improved. The specific technical scheme is as follows:

a sleeve tool for dismounting a butterfly nut is composed of a cylindrical barrel I, a cylindrical barrel II and a conical cambered surface; the cylindrical barrel body I and the cylindrical barrel body II form a whole through the conical cambered surface; cylindrical barrel I is close to the end and runs through two buckle holes along barrel diameter direction, and cylindrical barrel II is close to the barrel end and runs through two rectangular open slots of processing along barrel diameter direction.

furthermore, the cross section of the tail end of the cylindrical cylinder I is an inner quadrangular hole matched with a pneumatic or electric tool.

Furthermore, the cross section of the tail end of the cylindrical barrel II is a circular hole matched with the butterfly nut.

Furthermore, a through hole is formed in the center of a sleeve tool for disassembling and assembling the butterfly nut, and the diameter of the through hole is smaller than that of the inner four-corner hole and the circular hole.

Further, the diameter of the cylindrical barrel I is larger than that of the cylindrical barrel II.

The utility model has the advantages that: the utility model discloses manufacturing cycle is short, and is with low costs, utilizes the utility model discloses fastening locking force requirement when not only can satisfying the assembly of butterfly nut reduces staff intensity of labour simultaneously, improves the operation convenience, improves car assembly overall efficiency.

Those of ordinary skill in this and other arts will readily appreciate the spirit of the present invention based on the above structure of the present invention, with the addition of stickers or references, and make different extensions and changes, such as by changing the size of the major diameter barrel section adapter hole to accommodate different sized pneumatic or electric tools, or by changing the size of the minor diameter barrel section adapter hole or the size of the rectangular open slot to accommodate different sized wing nuts. Therefore, the method has extremely high popularization value.

Detailed Description

the present embodiment is specifically described below with reference to the drawings of the specification:

As shown in the attached figure 2, the sleeve tool 2 for dismounting the butterfly nut consists of a cylindrical barrel I2-3, a cylindrical barrel II2-2 and a conical cambered surface 2-4; the cylindrical barrel body I2-3 and the cylindrical barrel body II2-2 form a whole through the conical cambered surface 2-4; two buckling holes 2-5 are formed in the cylindrical barrel I2-3 close to the tail end in a penetrating mode along the diameter direction of the barrel, and two rectangular open grooves 2-1 are formed in the cylindrical barrel II2-2 close to the tail end of the barrel in a penetrating mode along the diameter direction of the barrel.

Referring to fig. 3, the cross section of the tail end of the cylindrical cylinder I2-3 is an inner quadrangular hole 2-7 matched with a pneumatic or electric tool.

1. As shown in figure 4, the end section of the cylindrical barrel II2-2 is a circular hole 2-6 matched with the butterfly nut 1. Referring to the attached figures 3 and 4, a through hole 2-8 penetrates through the center of a sleeve tool 2 for dismounting the butterfly nut, and the diameter of the through hole 2-8 is smaller than that of an inner four-corner hole 2-7 and a circular hole 2-6. The diameter of the cylindrical barrel I (2-3) is larger than that of the cylindrical barrel II (2-2).

as shown in the attached figure 1, the cylindrical barrel I2-3 of the sleeve tool 2 for disassembling and assembling the butterfly nut is connected with a pneumatic or electric tool through the buckle hole 2-5. When the butterfly nut assembling device works, the cylindrical barrel II2-2 is in butt joint with the butterfly nut 1, a circular hole 2-6 at the tail end of the cylindrical barrel is matched with a middle circular table of the butterfly nut 1, and two rectangular open grooves 2-1 at the tail end of the cylindrical barrel block left and right lugs of the butterfly nut 1, so that the butterfly nut 1 can be assembled and disassembled through a pneumatic or electric tool.

Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
