In use, it is horizontal to first pass through the end face progress that compression leg end face calibration block 7 is in contact to compression leg 52 with installation unit 1
Calibration.
Specifically, sliding part 22 is moved along the sliding rail 2111 of fixed bottom plate 211, fixing piece 23 passes through positioning match part edge
2131 synchronous slide of sliding slot of coulisse 213.When to be moved to the first needle plate positioning region 2121 and the second needle plate fixed for sliding part 22
When compression leg end face calibration block 7 is clamped between fixed side panel 212 and side board 214 by position portion 221, fixing piece 23 is tightened.At this point,
The portion 231 that is fixed and clamped of fixing piece 23 compresses coulisse 213, so that sliding part 22 can not continue on the sliding of sliding rail 2111, pressure
Position of the styletable face calibration block 7 on needle plate fixed mechanism 2 is fixed.
Then start compression leg actuator 53, so that the end face of compression leg 52 is in contact with the surface of compression leg end face calibration block 7.It sees
Whether the end face for examining compression leg 52 is bonded completely with the surface of compression leg end face calibration block 7.If the end face of compression leg 52 and compression leg end face
The surface of calibration block 7 is bonded the end face of compression leg 52 completely, then the end face of surface compression leg 52 is horizontal.If end face and the pressure of compression leg 52
The surface of styletable face calibration block 7 is not bonded completely, then the end face of surface compression leg 52 is not horizontal.It can be by adjusting compression leg actuator 53
Or adjustment compression leg 52 adjusts the end face of compression leg 52 to level.According to actual needs, the end face of multiple compression leg 52 can be carried out
Horizontal alignment, until the end face of compression leg 52 is horizontal.
After the completion of the horizontal alignment of the end face of compression leg 52, under compression leg end face calibration block 7 is dismantled from needle plate fixed mechanism 2
Come.Next the installation of needle guard 9 can be carried out.
Specifically, sliding part 22 is moved along the sliding rail 2111 of fixed bottom plate 211, fixing piece 23 passes through positioning match part edge
2131 synchronous slide of sliding slot of coulisse 213.When to be moved to the first needle plate positioning region 2121 and the second needle plate fixed for sliding part 22
When needle plate 8 is clamped between fixed side panel 212 and side board 214 by position portion 221, fixing piece 23 is tightened.At this point, fixing piece 23
Be fixed and clamped the compression coulisse 213 of portion 231, so that sliding part 22 can not continue on the sliding of sliding rail 2111, needle plate 8 is solid in needle plate
The position determined in mechanism 2 is fixed.If the surface area of needle plate 8 is larger, supporting element 3 can be taken out from instrument cases 4, by supporting element 3
It places on fixed bottom plate 211 and/or sliding rail 2111, to support needle plate 8.
Then needle guard 9 is placed at the fabrication hole for needing to install needle guard 9 of needle plate 8.Then it takes out and closes in instrument cases 4
The cooperation section 121 of the needle guard limit shaft 12 of the installation unit 1 is inserted into needle guard 9 by suitable installation unit 1.Needle guard limiting section at this time
122 offset with needle guard 9.
Followed by starting compression leg actuator 53, so that compression leg 52 is mobile towards needle plate 8.When the end face of compression leg 52 and positioning are led
When the second surface 1111 of body 11 is in contact, positioning body 11 and needle guard limit shaft 12 are mobile towards needle plate 8 together.Needle guard 9
It is pressed into the fabrication hole on needle plate 8.When positioning body 11, which is moved to first surface 1121, to be in contact with the surface of needle plate 8,
Positioning body 11 stops mobile towards needle plate 8.Length of embedment of the needle guard 9 in needle plate 8 no longer changes at this time, the needle guard 9 installation
It completes.
According to concrete technology demand, the installation of needle guard 9 can be repeated several times, until needle plate 8 needs to install the fabrication hole of needle guard 9
All it is installed.
