Embodiment one
Fig. 1 is please referred to, the embodiment of the present invention provides a kind of milling-boring machine Y-direction dragging system, including column 28 and spindle box 29,
The sliding block 31 that guide rail 30 is arranged on column 28 and moves on guide rail 30, sliding block 31 are fixedly connected with spindle box 29；In column
Ball-screw 12 and the ball-screw nut being equipped on ball-screw 12 15 are additionally provided between 28 and spindle box 29,
Ball-screw 12 accesses power source by shaft end, and ball-screw nut 15 is fixedly connected with spindle box 29.
As shown in Fig. 2, power source includes motor 1 and speed reducer 2, motor 1 is connect with speed reducer 2, motor 1, speed reducer 2,
The center of ball-screw 12 is located along the same line, i.e., motor 1, speed reducer 2 and ball-screw 12 are co-axially mounted；Motor 1 is through subtracting
Fast machine 2 delivers torque to ball-screw 12, and driving ball-screw 12 operates, and ball-screw nut 15 and spindle box 29 pass through the
Two screws 16 are connected and fixed connection, and ball-screw nut 15 holds up spindle box 29；Spindle box 29 is connected by screw in sliding block 31
On, sliding block 31 is moved along guide rail 30, and guide rail 30 is connect on column 28 by screw handle, movement of the spindle box 29 along 28 direction of column
For Y direction, ball-screw nut 15 drives 29 body of spindle box to slide on column 28 along guide rail 30, makees Y-direction movement；Such as Fig. 2
Shown, guide rail 30 is linear guide 30, and guide rail 30 is set as two, two sliding blocks 31, two guide rails are arranged on each guide rail 30
30 with the joint face of column 28 not in the same plane, two guide rails 30 are arranged on column 28 in high-low-position ladder, such
The torsional moment of spindle box 29 when four sliding blocks 31 can be made to evenly distribute processing is set, can reduce cnc boring and milling machine cutting when pair
The torque of column 28 reduces column 28 and deforms.
Motor 1 and speed reducer 2 all have band-type brake function, and internal contracting brake mechanism is normally off, when Y-direction does not feed instruction,
The internal contracting brake mechanism of motor 1 and speed reducer 2 is in locking state, prevents spindle box 29 from sinking, will not be because of master when lathe powers off suddenly
Axle box 29, which sinks, influences Y axis coordinate position, and lathe can continue to process after being powered, without again to knife.It is instructed when being connected to Y-direction feeding
Afterwards, the internal contracting brake mechanism of motor 1 and speed reducer 2 is in open configuration, and spindle box 29 can be moved along Y-direction at this time.
Locking system and motor 1 setting of motor 1 are integrated, and the locking system and speed reducer 2 of speed reducer 2 are set as one
Body.Speed reducer 2 and the integrated structure band-type brake moment of torsion of internal contracting brake mechanism after matching safety coefficient, are extremely difficult to little
The torque being self-possessed to balancing main shaft case 29, if choose speed reducer 2 according to band-type brake torque, 2 structure of speed reducer is huge and causes wave
Take, at this moment motor 1 matches band-type brake function, realizes the latch functions of Y-axis jointly with speed reducer 2, has higher economy and peace
Quan Xing.
Speed reducer 2 is fixed by screws in the seam allowance radial positioning on ring flange 3 and passing through speed reducer 2, and ring flange 3 passes through
First screw 4 is connected on support base 7, and is positioned by the first taper bolt 5.The output shaft of speed reducer 2 passes through yielding coupling 6
It is connect with the shaft end of ball-screw 12, square hole is provided on support base 7 and is easily installed adjustment and observes the work shape of yielding coupling 6
State, pass through outside square hole when normal work cover board 27 shown in FIG. 1 block it is dust-proof.Support base 7 is connected to by hexagon-headed bolt 14
It is positioned on column 28 and by the second taper bolt 13.
As shown in figure 3, ball-screw 12 is threaded through in support base 7, by three groups of deep groove ball bearings 9 to ball-screw 12 into
Row radial positioning compresses the both ends of the surface of three groups of 9 inner rings of deep groove ball bearing, to rolling by the first locking nut 8 and axle sleeve 11 respectively
Ballscrew 12 carries out axially position, and the outer ring of three groups of deep groove ball bearings 9 is in lash state without axially position.Axle sleeve 11 and branch
It supports dust-proof using the first outside framework oil seal 10 between seat 7.
12 other end of ball-screw is threaded through in bearing block 22, one end connecting flange lid 19 of bearing block 22, bearing block 22
The other end by the end of the fixed ball-screw 12 of the second locking nut 26, cylindrical roller thrust bearing is set in bearing block 22
20,12 other end of ball-screw is supported and is realized to the radial and axial of ball-screw 12 by cylindrical roller thrust bearing 20
Positioning, is provided with the first adjustment pad between the shaft shoulder of 12 other end of ball-screw and the inner ring end face of cylindrical roller thrust bearing 20
17, take match grinding mode to be used to finely tune the axial position of ball-screw 12.The outer ring of cylindrical roller thrust bearing 20 passes through third
Screw 21 is fixed on bearing block 22, and carries out dust-proof processing using the second outside framework oil seal 18 and third outside framework oil seal 25 respectively.
Bearing block 22 is fixed on 28 bottom of column by the 4th screw 23, with and equipped with second adjustment pad 24 to adjust bearing block 22 and stand
Fit dimension between column 28.
Active force when Y-direction is static and moves finally is concentrated by ball-screw 12 acts on cylindrical roller thrust bearing 20
On, three groups of deep groove ball bearings 9 on ball-screw 12 only radial positioning guarantees that ball-screw 12 is parallel with two guide rails 30, pushes away
Power cylinder roller bearing 20 will reserve biggish safety coefficient when selecting.
Milling-boring machine Y-direction dragging system provided in an embodiment of the present invention, after being connected to Y-direction feeding instruction, motor 1 and speed reducer
2 internal contracting brake mechanism is in open configuration, and spindle box 29 can be moved along Y-direction at this time.As shown in Figure 1, two on column 28 are led
Rail 30 is at high-low-position ladder arrangement, the torsional moment of spindle box 29 when four sliding blocks 31 evenly distribute processing.Y-direction is static and moves
When active force by ball-screw 12 finally concentrate act on cylindrical roller thrust bearing 20, the three of 12 upper end of ball-screw
The only radial positioning of deep groove ball bearing 9 is organized, guarantees that ball-screw 12 is parallel with two guide rails 30, cylindrical roller thrust bearing 20 selects
When to reserve biggish safety coefficient.
