Abstract
The invention aims to overcome the assembly defects of an existing 3D printing plastic part and designs a simple and reliable threaded assembly structure for the 3D printing plastic part. The threaded assembly structure comprises a round head screw and the plastic part with a metal nut embedded. The structure is mainly applied to the mechanical structure industry and efficiently solves the problems that a self-tapping screw cannot be disassembled frequently after being connected, and a threaded stud is cracked or the screw is loosened during assembly of a shell of the existing 3D printing plastic part.
Description
Technical field
The invention belongs to mechanical structure field, relate to a kind of 3D and print the Screw assembly structure of plastic parts.
Background technology
3D printing technique is developed rapidly at present, especially the most ripe with resin and plastic aspect.The rapid prototype manufacturing of product is one of main application of 3D printing technique, and the raw product that 3D prints is mainly used in the checking of outward appearance and function, or the shell etc. of be pilot.The typically exploitation early stage at new product makees the model machine that one or more 3D prints, and is used for assembling, does various experiments etc..Existing assembling mode is as shown in Figure 1: existing upper shell (1) and existing lower house (3) first pass through the location of seam and be assembled together, then by self-tapping screw (2) through existing upper shell (1), screw in the screw column of existing lower house (3), existing upper shell (1) and existing lower house (3) are fastenedly connected.Owing to existing lower house (3) is 3D printout, it is impossible to can be with pre-buried threaded insert as moulding, so screw column position can only be printed, reserved self-tap bottom outlet, finally screwed in by self-tapping screw, squeeze out screw thread.
Analyze the above-mentioned prior art mentioned to have the following disadvantages, i.e. the technical problem to be solved:
(1) self-tap should not often be dismantled, and otherwise can lose efficacy because of sliding tooth；And 3D printout can not be as moulding, can be with embedded nut；
(2) poor due to the precision of general plastic cement 3D printer, cause the tighten up a screw thread Pilot hole tolerance of post of the 3D plastic parts printed very big, produce assembly problem.Bottom outlet is the least, and self-tapping screw screws in difficulty, and is easily caused screw column cracking；Bottom outlet is too big, and screwed lock clamp force is inadequate, and the housing of accessory easily loosens.
Summary of the invention
It is an object of the invention to the assembling defect overcoming existing 3D to print plastic parts, design a kind of simple and reliable mounting structure.Including cheese head screw, the plastic parts of built-in metal nut.This structure is mainly used in frame for movement industry.Solve efficiently existing 3D print plastic parts housing assembling time, self-tapping screw connect can not often dismantle and screw column explosion or the problem of loosened screw.
To achieve these goals, the technical scheme is that by increasing a plastic parts with built-in metal nut, it is achieved the structure that machine tooth screw connects.Including: cheese head screw, the plastic parts of built-in metal nut.
Its annexation is: first, the plastic parts (12) of described built-in metal nut is inserted in the mounting groove of described lower house (14) from bottom to up, the buckle of the plastic parts (12) of described built-in metal nut clasping in described lower house (14) mounting groove tightly.Then, described upper shell (11) is installed on described lower house (14).Finally, described cheese head screw (13) is put in the screw hole of described upper shell (11), screw in the plastic parts (12) of described built-in metal nut, it is achieved screw-threaded coupling is assembled.
Advantages of the present invention with have the beneficial effects that: improve owing to 3D printout can not can only use self-tapping screw to carry out assembling (tapping screw thread should not often be dismantled, and otherwise can lose efficacy) because sliding tooth with pre-buried built-in metal nut as moulding.The present invention installs the plastic parts of built-in metal nut at 3D by printing on housing, it is achieved that the function of machine pitch thread assembling, screw locking is simple and reliable, and can often dismantle.The plastic parts convenient disassembly of built-in metal nut, can be recycled, cost-effective, saves the energy.

Detailed description of the invention
Being further described the detailed description of the invention of the present invention with embodiment below in conjunction with the accompanying drawings, following example are only used for clearly illustrating technical scheme, and can not limit the scope of the invention with this.
As shown in Figure 2, Figure 3, Figure 4, the technical scheme is that designing a kind of 3D prints the Screw assembly structure of plastic parts, including plastic parts (12), the cheese head screw (13) of built-in metal nut.
Wherein the plastic parts (12) of built-in metal nut can be by plastic mould injection batch production, and screw thread model makes standard component；Cheese head screw (13) is common machine tooth screw.
Its annexation is: the plastic parts (12) of described built-in metal nut is inserted in the mounting groove of described lower house (14) from bottom to up, the mounting groove of described lower house (14) and the plastic parts (12) of described built-in metal nut are that inclined-plane coordinates, on the plastic parts (12) of described built-in metal nut buckle can tightly clasp in described lower house (14) mounting groove, the six-freedom degree of the described plastic parts (12) burying metal nuts is just locked, do not fall out, and when also will not be screwed in by screw in follow-up installation process, stress comes off.
Described upper shell (11) is installed on described lower house (14)；Described cheese head screw (13) is put in the screw hole of described upper shell (11), screw in the embedded nut of plastic parts (12) of described built-in metal nut, owing to plastic parts (12) and the described lower house (14) of described built-in metal nut are that inclined-plane coordinates, when described cheese head screw (13) screws in locking when, the plastic parts of described built-in metal nut can compress described lower house (14), ensures that described lower house (14) and described upper shell (11) realize screw-threaded coupling assembling with this.
The above is only the preferred embodiments of the present invention; it should be pointed out that, for those skilled in the art, on the premise of without departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
