Specific embodiment
Specific embodiments of the present invention will be described in further detail by 1-5 with reference to the accompanying drawing.
It is a kind of for proofreading the device of eedle Yu rotating shuttle position.
As shown in Figure 1, all having shank 19, eedle 3, rotating shuttle 4, sewing-machine foot 7 and bottom plate 11, this is several in sewing machine
A component, those skilled in the art should know the working principle of sewing machine and clearly understand the position between each components
Relationship, therefore herein, the overall structure of sewing machine is no longer discussed in detail, and in the base for grasping above-mentioned well-known components
On plinth, carry out set forth below.
Specifically see Fig. 2, the present invention includes two verifying units, for proofreading the needle rod positioning device of the vertical distance of eedle 3
And the camera positioning device for proofreading 3 lateral distance of eedle, wherein needle rod positioning device includes chock 14, locating piece
15 and screw 18.
Specifically see Fig. 3, wherein camera positioning device includes fixing seat 2, magnet 10, locating plate 6, display screen 5, light compensating lamp
13 and camera 1, camera uses 100W pixel, the low coverage endoscopic camera of focal length 5mm-50mm.
In conjunction with Fig. 2, Fig. 3 and Fig. 4, slanting through slot 8 is offered in the middle part of 2 front end of fixing seat, is installed in through slot 8
Camera 1 is stated, locating plate 6 is installed in the two sides of fixing seat 2, the width between two locating plates 6 is not less than sewing-machine foot 7
Width, two locating plates 6 of fixing seat 2 are fitted in the outside of presser feet, fixing seat 2 are put into presser feet, and fixing seat 2 will lead to
Cross magnet 10 to be adsorbed on bottom plate 11, even if unclamping, will not cause to move easily, the upper surface of 2 front end of fixing seat at
Type has abutment face 12, and when the movement in terms of sewing-machine foot 7 by fixing seat 2 always, sewing-machine foot 7 can be abutted against
On face 12, camera 2 and eedle 3 at this time can take most standard between eedle 3 and rotating shuttle 4 in same axial position
Positional relationship will not lead to deviation since visual angle tilts, be also equipped with light compensating lamp 13 in the side of fixing seat 2, can make up for it
The problem of sewing machine internal optical fiber deficiency, keeps picture more limpid in sight, is conducive to installation personnel and is observed, in display screen 5
On be provided with the different scale 9 of thickness, employee by by eedle 3 and the line of the clearance distance of rotating shuttle 4 and corresponding normal width into
Row comparison, just can very easily differentiate, and whether gap between the two reaches professional standard, compared to relatively directly with the naked eye seeing
The eedle 3 and rotating shuttle 4 inside sewing machine are examined, picture passes through the amplification of 10 times even more big multiple, hence it is evident that there is very big difference,
For employee, visual fatigue is reduced, easier for installation, the quality of machine increases substantially.
The design of scale, is can be realized using the red graticule on Camera Measurey software in shielding, and is this field
The technical ability that technical staff can be realized without involving an inventive effort.
Specifically see Fig. 5, one end of chock 14 offers through-hole, and the periphery of shank 19, institute can be set in by the through-hole
State the location hole 16 for offering on locating piece 15 and passing through for shank 19, the side of location hole 16 offers through-hole 17, in through-hole 17
Be installed with screw 18, by adjusting screw 18 in the front-rear position of through-hole 17, can be realized adjust locating piece 15 and shank 19 it
Between tightness.
The specific proof-reading process of this programme is as follows:
Step 1: shank 19 being shaken into minimum point first, then the outer of shank 19 is inserted in one end of 2.2mm thickness chock 14
Week, and move up the top until blocking head；
Step 2: the side of locating piece 15 being passed through into shank 19 again, and is moved up after against chock 14, spiral shell is tightened
Nail 18, is fixed on locating piece 15 on shank 19；
Step 3: removing chock 14, and reversing handle, the locating piece 15 on shank 19 will be moved up until blocking machine
Behind the top of head, stop operating handwheel；
Step 4: fixing seat 2 being placed on the table top of bottom plate 11, and with the width of presser feet two sides, two locating plates 6 are fixed
The installation site of position 2 left and right sides of fixing seat is abutted against with the forward terminal of presser feet and is positioned 2 front and back side of fixing seat on face 12
Installation site, so that fixing seat 2 be moved into presser feet, camera 1 at this time can monitor position between eedle 3 and rotating shuttle 4
Picture, and will picture carry out 10 multiples amplification after be transferred on display screen 5；
Step 5: employee directly observes the real-time pictures on display screen 5, according to professional standard: real between rotating shuttle 4 and eedle 3
The gap on border should be 0.03mm-0.05mm, 10 times of difference between the picture and actual picture shown according to display screen, aobvious
The different scale 9 of corresponding multiple thickness is set in display screen 5, should as show that the width of graticule is 0.3m- on display screen 5
0.5m is compared with the spacing on display screen 5 between rotating shuttle 4 and eedle 3, is debugged；
Step 6: after the completion of debugging, tightening screw and fix, complete the installation of eedle rotating shuttle, the magnified picture of 10 multiples, phase
When the quality of machine being greatly improved, while reducing and the operation of employee is wanted in the installation accuracy for improving 10 times
It asks, the present inventor is by many experiments, and the case where being integrated to cost and practical operation, the amplification factor using 10 times is the most excellent
The scheme of choosing, in actual use, can also picture slightly lower by other or more high magnification numbe be adjusted.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
