DT/DM - Spider koppelingsaandrijving - Spil - Vervanging

Inleiding

Voer deze procedure uit voor een DM-1 of een DT-1. Deze procedure vertelt u hoe u de spil vervangt. Machines die gebouwd zijn na januari 2014 gebruiken een mid-Point oliën (MPO) spil. U zult een MPO-spil gebruiken wanneer u de spil vervangt.

Spindle Installation Preparation

1

Clean the spindle head bore.

Stone the mating surface [1] on the spindle head casting.

Clean the motor adapter where it touches the spindle [3].

Do not stone the spindle lubrication port [2]. Keep all contamination out of the port.

2

Replace the spider coupling [1] if it is worn or damaged.

Replace the transfer tube [2] if it is worn or damaged.

Mid-Point Oiling (MPO) Spindle - Installation

Do not remove the tape from the lubrication port.

Use a lift to support the motor until the spindle is attached.

 Important: Refer to the DT-1 - Mid-Point Oiling (MPO) - Spindle - Minimum Lubrication - Oil Pump Modification procedure.

1

Attach the red protective cap [2] to the bottom of the MPO spindle.

Put a 6" x 6" x 6" (152 mm x 152 mm x 152 mm) wood or aluminum block [3] on the table.

Put the MPO spindle on the block.

Make sure that the spindle lubrication port [1] is in the front.

Put a long 5/16"-18 screw [4] through the rear hole on the motor adapter. This screw helps you align the motor adapter to the spindle.

2

Put an indicator against the spindle coupler [1]. Zero the indicator.

Slowly turn the spindle with your hand to find the highest point on the coupler.

Put a mark on the point with a permanent marker.

Examine the coupler on the motor [2].

If the motor coupler has a mark, proceed to step 3.

If the motor coupler does not have a mark:

  • Put an indicator against the motor coupler [2]. Zero the indicator.
  • Slowly turn the motor by hand to find the highest point.
  • Use a permanent marker to mark the point.

3

Apply grease to the transfer tube at these locations:

  • the o-ring [1] at the top
  • the socket [2] for the o-ring on the draw bar.

Push the transfer tube [4] onto the top of the draw bar [5].

Install the spider coupler [3].

4

Remove the tape [1] from the spindle lubrication port.

Apply a small quantity of grease to the spindle seal o-ring [2].

Insert the o-ring into the lubrication port [3].

Put the tape over the lubrication port of the spindle that was removed.

5

Slowly jog the Z Axis in the negative (-) direction until the head mount [1] is 0.5" (13 mm) above the spindle flange [2].

Use your hand to slowly turn the spindle coupler [5] until the mark on the spindle coupler aligns with the mark [4] on the motor coupler [3]. Align the (2) marks as closely as possible.

Slowly jog the Z Axis in the negative (-) direction.

 Caution: Lower the lift as you jog the Z Axis. The motor must be supported by the lift until the spindle is connected to the motor adapter.

Make sure the spindle is centered in the spindle bore.

Make sure the couplers engage smoothly.

6

Remove the temporary screw you used in step 1.

Install (4) motor mount screws [1] into the motor mount adapter [2].

Torque the screws. Refer to Haas Fastener Torque Specifications.

Remove the motor support lift.

Attach the oil supply fitting.

Connect the oil supply tube.

7

Put (4) screws [1] into the upper inside bearing block of the rocker assembly.

Put (4) screws [9] into the outer bearing block.

Put the rocker assembly [3] onto the spindle casting. Use the lower bearing block [2] on the inside as a guide.

Use a dowel pin [8] to align the outside bearing block.

Put the rocker arm [7] through the yoke [5] on shaft from the air cylinder.

Push the clevis pin [4] through the arm and the yoke.

Put the C-clip [6] onto the clevis pin.

Torque all of the screws. Refer to the Haas Fastener Torque Specifications.

Make sure the rocker assembly is correctly adjusted.

 Note: The illustration does not show the spindle and spindle motor.

8

Use the spring installation tool to attach the spring to the striker block.

Refer to DT-1 - Spindle Rocker Arm - Spring Installation Tool - Instructions.

Install the fan assembly onto the top of the spindle head.

Install the spindle head covers.

9

Refer ro the VMC - Spindle - Alignment ("Spindle Sweep") procedure.

Spindel verwijderen

1

JOG de Z-as naar de onderkant van de reis.

Druk op [EMERGENCY STOP].

Verwijder de spil ventilator assemblage.

Verwijder de rocker arm-eenheid. Volg deze stappen:

  • Verwijder de C-clip [5] van de gaffel-PIN [6]. Druk op de gaffel-pin om deze te verwijderen.
  • Koppel de veer [4] los van het stootblok.
  • Draai de (4) schroeven [1] los van het binnenlagerblok [2].
  • Draai de (4) schroeven [7] los van het externe lagerblok [8].
  • Verwijder de rocker arm-eenheid uit het apparaat.
  • Verwijder de onderste helft [3] van het binnenste lagerblok niet.
  • Verwijder de deuvel pennen van de lagerblokken.

 Opmerking: De afbeelding toont niet de spil-en spilmotor.

2

JOG de X-en Y-as totdat de tabel zich direct onder de spil bevindt.

Druk op [EMERGENCY STOP].

Zet een 6" x 6" x 6" (152 mm x 152 mm x 152 mm) hout of aluminium blok [2] op de tafel.

Bevestig de beschermkap [1] op de spil die in de machine is geïnstalleerd.

Laat de [EMERGENCY STOP] los.

Druk op [RESET] om de alarmen te wissen.

JOG de Z-as in de negatieve (-) richting totdat de spil op het blok rust.

Druk op [EMERGENCY STOP].

Bevestig een lift aan de beugel [3] voor de encoder.

 Waarschuwing: Wanneer de spil van de motor adapter wordt gescheiden, moet het motor stel door de lift worden ondersteund.

3

Koppel de olietoevoer buis los.

Verwijder de fitting van de olietoevoer.

Verwijder de (4) schroeven [2] die de motor adapter [1] aan de spil bevestigen.

Druk op [RESET] om de alarmen te wissen.

JOG de Z-as langzaam in 0,001" stappen in de positieve (+) richting naar een afstand van 0,04" (1 mm).

 Opmerking: De spil [2] DROPS 1/32" (1 mm) van de spil gieten [1].

Als de spil niet daalt, gebruik dan een riem sleutel om de spil te draaien 1/4 Draai rechtsom om deze los te maken.

Gebruik de takel om de motor te verhogen [3] op hetzelfde moment dat u de Z-as JOG.

JOG de Z-as in de positieve (+) richting totdat u de spil verwijderen [4].
