Description
Technical field
The utility model relates to sewing machine field, especially a kind of electrical motor of sewing machine injection molding machine shell injection molding end cover attaching structure.
Background technology
Casing and the end cap injection moulding of electrical motor of sewing machine are made, can weight reduction and reducing costs; Hex nut is embedded in the casing of injection mo(u)lding, although can assembly tool be reduced, there is the deficiency that the easy off normal of hex nut causes assembling difficulty; Therefore, design one both can reduce assembly tool, made again electrical motor of sewing machine injection molding machine shell injection molding end cover attaching structure easy to assembly, became problem demanding prompt solution.
Utility model content
The purpose of this utility model is embedded in the casing of injection mo(u)lding by hex nut at present to overcome, although can assembly tool be reduced, but there is the deficiency that the easy off normal of hex nut causes assembling difficulty, there is provided one both can reduce assembly tool, make again electrical motor of sewing machine injection molding machine shell injection molding end cover attaching structure easy to assembly.
Concrete technical scheme of the present utility model is:
A kind of electrical motor of sewing machine injection molding machine shell injection molding end cover attaching structure, comprises injection molding machine shell, is provided with the injection moulding end cap of several accessibke porosities, the attachment screw that number is identical with accessibke porosity number and hex nut; The gusset of described injection molding machine shell is provided with the groove that number and thickness identical with accessibke porosity number is greater than hex nut thickness; The end face of injection molding machine shell is provided with number and that respectively with a groove be communicated with inner via hole identical with accessibke porosity number; The axis of inner via hole and the distance of groove one side are greater than the axis of hex nut and the distance of side, and the axis of inner via hole and the distance of groove one side are less than the distance between the axis of hex nut and angle; Each hex nut is arranged in a groove; The screw rod of each attachment screw is through an accessibke porosity and an inner via hole and be threaded with a hex nut.This electrical motor of sewing machine injection molding machine shell injection molding end cover attaching structure can reduce assembly tool, makes again easy to assembly.
As preferably, the rear end face of described groove is provided with accommodating counterbore; The screw front end of attachment screw stretches in accommodating counterbore.The thickness of groove can be made to improve intensity close to the thickness of hex nut.
As preferably, described inner via hole coordinates with the screw clearance of attachment screw; Accessibke porosity coordinates with the screw clearance of attachment screw.Make assembling more smooth.
Compared with prior art, the beneficial effects of the utility model are: this electrical motor of sewing machine injection molding machine shell injection molding end cover attaching structure can reduce assembly tool, makes again easy to assembly.The rear end face of groove is provided with accommodating counterbore, and the thickness of groove can be made to improve intensity close to the thickness of hex nut.Inner via hole coordinates with the screw clearance of attachment screw, and accessibke porosity coordinates with the screw clearance of attachment screw, makes assembling more smooth.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the A-A view of Fig. 1.
In figure: injection molding machine shell-1, groove-11, inner via hole-12, accommodating counterbore-13, injection moulding end cap-2, accessibke porosity-21, attachment screw-3, hex nut-4.
Embodiment
Below in conjunction with shown in accompanying drawing, the utility model is described further.
As shown in accompanying drawing 1, accompanying drawing 2: a kind of electrical motor of sewing machine injection molding machine shell injection molding end cover attaching structure, comprises injection molding machine shell 1, be provided with the injection moulding end cap 2 of four accessibke porosities 21, four attachment screws 3 that number is identical with accessibke porosity 21 number and four hex nuts 4; The gusset of described injection molding machine shell 1 is provided with four grooves 11 that number and thickness identical with accessibke porosity 21 number is greater than hex nut 4 thickness; The end face of injection molding machine shell 1 is provided with number and that respectively with a groove 11 be communicated with four inner via holes 12 identical with accessibke porosity 21 number; The axis of inner via hole 12 and the distance of groove 11 1 side are greater than the axis of hex nut 4 and the distance of side, and the axis of inner via hole 12 and the distance of groove 11 1 side are less than the distance between the axis of hex nut 4 and angle; Each hex nut 4 is arranged in a groove 11; The screw rod of each attachment screw 3 is through an accessibke porosity 21 and an inner via hole 12 and be threaded with a hex nut 4.
The rear end face of described groove 11 is provided with accommodating counterbore 13; The screw front end of attachment screw 3 stretches in accommodating counterbore 13.
Described inner via hole 12 coordinates with the screw clearance of attachment screw 3; Accessibke porosity 21 coordinates with the screw clearance of attachment screw 3.
The beneficial effects of the utility model are: this electrical motor of sewing machine injection molding machine shell injection molding end cover attaching structure can reduce assembly tool, makes again easy to assembly.The rear end face of groove is provided with accommodating counterbore, and the thickness of groove can be made to improve intensity close to the thickness of hex nut.Inner via hole coordinates with the screw clearance of attachment screw, and accessibke porosity coordinates with the screw clearance of attachment screw, makes assembling more smooth.
It is apparent to one skilled in the art that the utility model can change into various ways, such change do not think depart from scope of the present utility model.All like this to the apparent amendment of the technical staff in described field, by be included in this claim scope within.
