Technical field
The utility model relates to a kind of scanning motor, more particularly, relates to a kind of eyeglass fixed sturcture of scanning motor.
Background technology
As shown in Figure 1, in existing scanning motor rotor set, comprise axle 1 and be connected the rotating disc 2 of axle on 1.Rotating disc 2 is multistage cylindrical for what diminish by rank.On the single order, be provided with reference field therein, eyeglass 3 is sheathed on the rotating disc 2, and its bottom contacts with reference field.Above eyeglass 3, be provided with balancing frame 4.For eyeglass 3 is close on the reference field of rotating disc 2, above balancing frame 4, be provided with claw type pressing plate 6.Clasp 5 is arranged on claw type pressing plate 6 tops, and is connected in rotating disc 2 by the riveted joint mode, and compressing claw type pressing plate 6 makes it produce deformation, thereby certain pressure is provided, and eyeglass 3 and balancing frame 4 are close on the reference field of rotating disc 2.The defective of this structure is that owing to will rivet, assembling is relatively complicated, and cost is longer man-hour; When rotor set occur unusual after, inconvenience is disassembled, and easily portion's product is damaged when disassembling.
The utility model content
The technical problems to be solved in the utility model is, at the above-mentioned defective of prior art, provides a kind of eyeglass fixed sturcture of easy-to-mount scanning motor.
The technical scheme that its technical matters that solves the utility model adopts is: the eyeglass fixed sturcture of constructing a kind of scanning motor, comprise one and be connected a rotating disc on the described axle, the multistage cylindrical disk body of described rotating disc for diminishing by rank, one eyeglass is located on first rank of described rotating disc by its center borehole jack, the center pit of one balancing frame bottom it is sheathed on next-door neighbour first rank and is positioned on second rank of its top, wherein, described rotating disc comprises also and has externally threaded the 3rd rank that described the 3rd rank are close to second rank and are positioned at its top; The eyeglass fixed sturcture of described scanning motor comprises that also one has the pressing plate of internal thread; Described pressing plate matches by the external thread of its internal thread with described the 3rd rank.
In the eyeglass fixed sturcture of scanning motor described in the utility model, described pressing plate bottom is provided with a hole, and its diameter is greater than the diameter on described second rank.
In the eyeglass fixed sturcture of scanning motor described in the utility model, the thickness of described eyeglass equals the height on described first rank.
In the eyeglass fixed sturcture of scanning motor described in the utility model, the thickness of described balancing frame bottom equals the height on described second rank.
In the eyeglass fixed sturcture of scanning motor described in the utility model, the thickness of described pressing plate is less than the height on described the 3rd rank.
In the eyeglass fixed sturcture of scanning motor described in the utility model, described eyeglass top is provided with the fixed orifice that is communicated with its center pit, and its diameter is greater than the base diameter of described balancing frame.
Implement the eyeglass fixed sturcture of scanning motor of the present utility model, have following beneficial effect: assemble easylier, reduced man-hour, enhance productivity; Simple in structure, can carry out large-scale production; When the situation of quality abnormal appears in scanning motor, also can decompose easily, can not damage each product; Portion's product after disassembling can put into production again, have reduced waste, help reducing cost.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the partial sectional view of the eyeglass fixed sturcture of existing scanning motor;
Fig. 2 is the partial sectional view of eyeglass fixed sturcture when assembled state of scanning motor of the present utility model;
Fig. 3 is the partial sectional view of eyeglass fixed sturcture when decomposing state of scanning motor of the present utility model.
Embodiment
As shown in Figures 2 and 3, in the embodiment of the eyeglass fixed sturcture of scanning motor of the present utility model, eyeglass fixed sturcture 100 comprises axle 1, is connected the rotating disc 2 on the axle 1, and is arranged on eyeglass 3, balancing frame 4 and pressing plate 12 on the rotating disc 2.The rotating disc 2 multistage cylindrical disk body for diminishing by rank, reference field 7 are positioned on the end face of single order wherein.Eyeglass 3 is located on first rank 8 of reference field 7 tops by its center borehole jack, and its thickness equals or be slightly larger than the height on first rank 8, and the bottom surface contacts with reference field 7.
The 3rd rank 10 are close to second rank 9 and are positioned at 9 tops, second rank, and its base diameter is littler than main diameter, and main body is provided with external thread 11.Pressing plate 12 has internal thread 13, and is sheathed on the 3rd rank 10 by the engagement of internal and external screw thread, and its thickness is less than the thickness on the 3rd rank 10.It is porose 15 that the bottom of pressing plate 12 also is provided with, and its diameter makes pressing plate 12 bottoms form an annular root edge 16 greater than the diameter on second rank 9.Therefore, regardless of the height relationships on the balancing frame 4 and second rank 9, by the annular root edge 16 and balancing frame 4 permanent contacts of pressing plate 12, the bottom circumference of pressing plate 12 all can fit tightly on balancing frame 4 after the assembling.
In assembling process, axle 1 is sheathed on eyeglass 3 and balancing frame 4 respectively on first rank 8 and second rank 9 of rotating disc 2 successively with after rotating disc 2 is fixedlyed connected, and then pressing plate 12 is fixed on the 3rd rank 10 of rotating disc 2 by the mode that is threaded.Because pressing plate 12 bottoms are provided with porose 15, and its diameter is greater than the diameter on second rank 9, therefore, after internal thread 13 is screwed on the external thread 11 fully, still can continue to be rotated down, balancing frame 4 is exerted pressure, guarantee that eyeglass 3 and balancing frame 4 closely are fixed on the reference field 7 of rotating disc 2, it is firm, accurate to locate.
Compare the fixing knot of the eyeglass of scanning motor of the present utility model with riveted joint fixed structure of the prior art Structure is easier when assembling, has reduced man-hour, enhances productivity; Simple in structure, can carry out extensive Produce; When the situation of quality abnormal appears in scanning motor, also can decompose easily, can be to each Component damages; Component after disassembling can put into production again, has reduced waste, is conducive to reduce cost.
