Abstract
The utility model relates to a small motor assembling tool which includes a pedestal. The pedestal is provided with an installing column. The top of the installing column is an outer shell positioning end which is sleeved by an outer shell of a motor. The center of the top of the installing column is provided with a central hole which is inserted with a central shaft of the motor. The tool also includes a positioning sleeve sleeved on the installing column and a top needle movably inserted in the positioning sleeve. An inner wall of the positioning sleeve has a sliding contact with an outer wall of the outer shell of the motor. The height of the positioning sleeve is higher than the height of the installing column. The top needle, a positioning sleeve inner hole, the outer shell positioning end, and the central hole are coaxial. The tool is concise in structure and is easy to use. A method combined with the tool can make the assembly operation more rapid, the assembly quality more stable, and the product reject ratio lower. The outer shell of the motor and the central shaft of the motor can not be deformed in assembly. After assembly, the tightness and stability can be guaranteed, the concentricity and coaxiality are high, and the performance of each aspect can satisfy the design requirements.
Description
Technical field
The utility model relates to a kind of miniature motor packaging technology.
Background technology
Be depicted as shaft-assembling structure sketch map in existing a kind of miniature motor shell and the motor like accompanying drawing 1.This motor case 5 is stamping forming thin cylinder shape with motor axis 6.Wherein motor case is a tubbiness, and bottom centre's outward flanging forms the hole of interting the motor axis.The motor axis is the housing of step axle shape, and end external diameter hole interference fit big, that be used for bottom motor case is located.In the assembling of existing motor case and motor axis; Generally be to be positioned the bigger end of motor axis external diameter on the special fixture up earlier; Then motor case is placed in outside the motor axis from top to down, the bigger end of shaft diameter in the motor is snapped in the hole of motor case bottom.Because between motor case and the motor axis be interference fit, so the motor axis receives the extruding easy deformation of motor case when assembling, and influences motor axis and motor case and assembles firm degree and concentricity.
The utility model content
In view of this, one of the utility model technical problem that will solve provides a kind of easy to use, firm miniature motor assembled fixture of assembling back product structure.
Thus, the utility model adopts following scheme to realize:
A kind of miniature motor assembled fixture; Comprise a base; Base is provided with an erection column, and the erection column upper end is the shell positioning end of sheathed motor case, and center, erection column upper end is provided with the centre bore of interspersed motor axis; This tool comprises that also one is placed in the outer positioning sleeve of erection column and movable and is interspersed in the thimble in the positioning sleeve; Positioning sleeve inwall and the sliding contact of motor case outer wall, the positioning sleeve height is higher than the erection column height, thimble, positioning sleeve endoporus, shell positioning end and the equal concentric of centre bore.
Wherein, the lower end that contacts with the motor axis of described thimble is provided with one and is used for preventing that the motor axis is out of shape, is interspersed in the top of motor axis when being pressed into motor case.
The jig structure that the utility model discloses is succinct, easy to use, and the method that combines with it can make assembling work quicker; Product assembly quality is more stable; Can reduce the fraction defective of product greatly, when assembling, can guarantee that motor case and motor axis can not be out of shape, assembling back firm, stable; Concentricity and axiality are high, and various aspects of performance all can meet design requirement.
Description of drawings
Fig. 1 is shaft-assembling structure sketch map in existing miniature motor shell and the motor;
Fig. 2 is the utility model embodiment miniature motor assembled fixture structural representation;
Fig. 3 is a present embodiment tool cross-sectional view;
Fig. 4 is a present embodiment tool decomposing state structural representation;
Fig. 5~Figure 12 is for adopting present embodiment tool assembling motor case and motor axis schematic flow sheet.
Embodiment
For ease of those skilled in the art's understanding, the utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
Shown in accompanying drawing 1~4.The miniature motor assembled fixture that present embodiment discloses is used to assemble the motor case 5 and motor axis 6 of the miniature motor shown in accompanying drawing 1, with concentricity, axiality, the peel strength that motor axis 6 can satisfy two parts strict demand is arranged all through the motor case 5 after this tool assembling.
In the present embodiment, the miniature motor assembled fixture that is adopted comprises a base 1, and base 1 is provided with an erection column 2, and erection column 2 upper ends are the shell positioning end 21 of sheathed motor case 5, and center, erection column 2 upper end is provided with the centre bore 22 of interspersed motor axis 6.In addition; This tool comprises that also one is placed in the outer positioning sleeve 3 of erection column 2 and movable and is interspersed in the thimble 4 in the positioning sleeve 3; Positioning sleeve 3 inwalls and motor case 5 outer wall sliding contacts; Positioning sleeve 3 highly is higher than erection column 2 height, thimble 4, positioning sleeve 3 endoporus, shell positioning end 21 and centre bore 22 equal concentrics.In order to prevent that motor axis 6 is out of shape when being pressed into motor case 5, the lower end that thimble 4 contacts with motor axis 6 is provided with one and is interspersed in top 41 in the motor axis 6.This tool cooperates through each parts accurately; Can easily motor axis 6 be installed in the motor case 5; And the defective that motor axis 6 is out of shape can not occur, can guarantee concentricity, axiality, the peel strength of motor axis 6 and motor case 5, greatly reduce the fraction defective of product.
Accompanying drawing 5~12 is depicted as the schematic flow sheet that adopts above-mentioned tool assembling motor case 5 and motor axis 6 for another example.To combine accompanying drawing that such motor case 5 is described with motor axis 6 assemble methods below.
This method comprises the steps:
At first motor case 5 is placed in shell positioning end 21,, then motor axis 6 is interspersed in the motor case 5, like accompanying drawing 7~shown in Figure 8 like accompanying drawing 5~shown in Figure 6; Again positioning sleeve 3 is placed on motor case 5 and the erection column 2, like accompanying drawing 9~shown in Figure 10; Afterwards thimble 4 is interted in the positioning sleeve 3; And make top 41 to extend in motor axis 6 upper ends downwards; Press down thimble 41 again motor axis 6 upper ends are got in the motor case 5 fully, accomplish the assembling of motor case 5 and motor axis 6 thus, like accompanying drawing 11~shown in Figure 12.
Can find out by said method, adopt this tool and method assembling motor case 5 and motor axis 6 very convenient, quick, improve the production rate greatly.
The foregoing description is merely the preferred embodiments of the utility model, need to prove, has other conspicuous variations down based on this design, and such variation is within the claim protection range of the utility model.
