In order to overcome the shortcomings of background technique, the utility model provides a kind of at low cost, and mechanical strength is big, and operation torque is big
Embedded nut.
Technical solution adopted by the utility model: a kind of embedded nut, the nut cylinder including being equipped with centre bore is described
The circumferential surface of nut cylinder is successively disposed adjacent in bumps, the nut cylinder integrally casting shaping.
The circumferential surface of the nut cylinder is equipped with the uniformly distributed pocket of several equal parts.
The pocket be in strip groove, be separately positioned on the nut main body lean on two close end position, and respectively with nut
The both ends end face of cylinder is connected to.
The middle section position of the nut main body is arranged in the pocket, and is not connected to the both ends end face of nut cylinder.
The pocket is in strip groove, and is connected to one end end face of nut cylinder.
The circumferential surface of the nut cylinder is equipped with the uniformly distributed boss portion of several equal parts.
The centre bore uses through-hole or half counterbore.
The nut cylinder uses non-copper metal or alloy.
The nut cylinder uses cylindrical body, polygonal cylinder or irregular cylinder.
The beneficial effects of the utility model are:
1, the embedded nut both ends in the application use monoblock cast, and high mechanical strength makes part in subsequent screw tap, and two
End is not easily broken, and the overall dimensions of components can be made smaller, reduces material consumption, and improve part strength, promotes part matter
Amount, is formed using non-copper metal (or non-copper alloy) cast, and using casting one-shot forming technique, manufacturing procedure subtracts significantly
It is few, it there's almost no waste of material, stock utilization greatly improves, and cost of parts declines to a great extent.
2, in addition, cavity formula or projective table type structure are used in the middle part of the embedded nut of the application, with mach processing side
Formula is compared, and the application embedded nut overall mechanical strength is higher, and can generate bigger torque after nut is embedded in part.
3, the application embedded nut uses casting and forming, is conducive to nut dimensional uniformity, for client, reduces matter
Buret control difficulty, reduces quality risk.

Specific embodiment
The utility model embodiment is described further with reference to the accompanying drawing:
As shown, a kind of embedded nut, the nut cylinder 1 including being equipped with centre bore 4, the circumferential direction of the nut cylinder 1
Face is successively disposed adjacent in bumps, and cavity formula or projective table type structure are used in the middle part of the embedded nut of the application, and mach
Processing method is compared, and the application embedded nut overall mechanical strength is higher, and can be generated bigger after nut is embedded in part
Torque.
1 integrally casting shaping of nut cylinder, the nut cylinder 1 use non-copper metal or alloy, the nut
Cylinder 1 is using cylindrical body, polygonal cylinder or irregular cylinder.
Embedded nut in the present embodiment can be divided into A type embedded nut and Type B embedded nut, whole to use non-copper gold
Belong to cast to form, whole is in cylinder.Due to the technique of embedded nut are as follows: after melting non-copper metal material, pour into mould
Tool one-step casting forms, thus have manufacturing procedure is simpler, part size is more stable, the time-consuming short, material use of process compared with
Advantage high, processing cost is lower.
New embedded nut is integrally cast using non-copper metal material, can use aluminium and its alloy, zinc and its alloy etc.
Cheap metal or alloy substitutes former copper metal material, effectively reduces precious metal consumption as copper, has
The material cost and processing cost for reducing part of effect.
The centre bore 4 uses through-hole or half counterbore, and A type embedded nut is as shown in Fig. 2, Type B embedded nut such as Fig. 3 institute
Show, formed by mold one-step casting, production efficiency is higher, will not generate biggish waste of material, significantly reduce material at
This.Especially for Type B embedded nut, due to being casting and forming, bottom can be cast relatively thin, without drill bit top
The case where breaking in two counterbore base can make part be suitable for more occasions, increase part to obtain longer half counterbore
Versatility.
Through-hole or half counterbore can be threaded hole, since half counterbore is longer than half counterbore of existing inserts, so it has spiral shell
The length of line is also longer, and nut can be made to be suitable for more occasions, increase the versatility of part.
There are two following examples for the technical program:
Embodiment one, the nut cylinder 1 circumferential surface be equipped with the uniformly distributed pocket 2 of several equal parts；The pocket
The middle section position of the nut main body is set, and is not connected to the both ends end face of nut cylinder 1.
Embodiment two, the nut cylinder 1 circumferential surface be equipped with the uniformly distributed boss portion (not shown) of several equal parts.
The cylinder surrounding of embedded nut has pocket or boss portion, to generate axial tension and rotation torque, due to recessed
Cavity portion or boss portion are formed by mold one-step casting, and production efficiency is higher, will not generate biggish waste of material；And due to
Axial tension and rotation torque are all generated by cavity or boss, and bite force is bigger after cavity and boss insertion plastic part, institute
Bigger axial tension and rotation torque can be generated.
Other than cavity as shown in Figure 1, there are also other cavity plans of establishment, embodiments three: such as such as Fig. 4 institute
Show, is divided into two rows, and the pocket of two rows shifts to install, can also be arranged in a one-to-one correspondence up and down；The pocket
In strip groove, it is separately positioned on the position that the nut main body leans on two close end, and is connected respectively with the both ends end face of nut cylinder 1
It is logical.
Example IV: for another example as shown in figure 5, an only row, the pocket is in strip groove, and with nut cylinder 1
The connection of one end end face, effect and effect are all as above-mentioned technical proposal.
Embedded nut both ends in the application use monoblock cast, and high mechanical strength makes part in subsequent screw tap, both ends
It is not easily broken, the overall dimensions of components can be made smaller, reduce material consumption, and improve part strength, promote part quality,
It is formed using non-copper metal (or non-copper alloy) cast, using casting one-shot forming technique, manufacturing procedure greatly reduces,
It there's almost no waste of material, stock utilization greatly improves, and cost of parts declines to a great extent.
The application embedded nut uses casting and forming, is conducive to nut dimensional uniformity, for client, reduces quality
Difficulty is managed, quality risk is reduced.
