Abstract
The utility model discloses a kind of PCB numerical control drilling machines Z axis grating reading head positioner.Including guide pad, homophony whole plate, auxiliary adjustment plate, and the grating reading head in auxiliary adjustment plate, parallel Z axis and the grating scale being arranged on drill bit motor cabinet, it is characterised in that：The guide pad is parallel to Y-axis and is arranged at Z axis lathe bed, and homophony whole plate coordinates along Y-axis and guide pad to be arranged on PCB numerical control drilling machine Z axis lathe beds, and auxiliary adjustment plate is vertically mounted in homophony whole plate.Compared to the method being directly adjusted in the past using bolt and bolt hole, this positioner adjustment amplitude is bigger, and adjustment direction zero deflection, low to lathe bed screwed hole position accuracy demand in theory, entirely adjusts process flexible, easy to adjust reliable.
Description
Technical field
The utility model is related to the position feedback device grating scale in PCB drilling machines, and in particular to the light of drilling machine Z axis part
The positioning of grid read head.
Background technology
PCB drilling machine bore motor high-speed cruisings, to improve machining accuracy, light is needed using the digital control system of half-closed loop control
Learn measurement and carry out Real-time Feedback bit location, therefore the relative position of grating reading head and grating scale is had higher requirements.Grating scale with
The motor cabinet for installing motor is together moved, so the general position for adjusting grating reading head during adjustment.General manufacturing enterprise is installing
The positioning directly coordinated during grating reading head using bolt hole and screwed hole and fastening means, because bolt hole does not possess positioning in itself
Function, though there is small―gap suture, the amplitude of adjustment is small, and in order to ensure the distance of read head and grating scale, to for installing read head
Lathe bed screwed hole status requirement is very high, and the deflection of grating reading head is easily caused when installing, and this positioning method serious forgiveness is low.
A kind of PCB numerical control drilling machines Z axis grating reading head positioner of the utility model, is oriented to using straight trough and is mutually tied with waist-shaped hole
The positioning method of conjunction.Straight trough is oriented to and can control adjustment direction well and be difficult not deflect, and waist-shaped hole has bigger compared with bolt hole
Adjusting range, so as to realize the adjustment in fixed-direction certain length region, two pieces of adjustment plates designs can then meet two
The adjustment in direction.
The content of the invention
The utility model need solve the problem of be：A kind of PCB numerical control drilling machines Z axis grating reading head positioner is provided, it is real
The large range of accurate adjustment of existing grating scale grating reading head installation site.
In order to solve the above technical problems, the utility model uses following technical scheme：Guide pad is fixed on PCB numbers along Y-axis
Drilling machine Z axis lathe bed is controlled, homophony whole plate coordinates adjustment to be arranged on Z axis lathe bed with guide pad, and vertically adjustment is arranged on master to auxiliary adjustment plate
In adjustment plate, grating reading head is arranged in auxiliary adjustment plate.
The guide pad, is a four-prism bloom, is bonded in metal-to-metal adhesive on drilling machine lathe bed.
The homophony whole plate, for the adjustment plate for adjusting Y-direction position, be machined with a guide groove, two be parallel to each other
Waist-shaped hole, a convex and two screwed holes；Homophony whole plate can be moved in the case where guide groove and guide pad coordinate in Y-direction, waist type
Hole controls displacement, is then anchored on bolt by waist-shaped hole on lathe bed；Convex and screwed hole are used to connecting and adjusting auxiliary
Adjustment plate.
The auxiliary adjustment plate, for for adjusting adjustment plates of the X to position, be machined with a guide groove, two be parallel to each other
Waist-shaped hole and two screw holes for fastening grating reading head；Auxiliary adjustment plate is in the case where guide groove and the convex of homophony whole plate coordinate
Can be in X to movement, then waist-shaped hole control displacement is anchored in homophony whole plate with bolt by waist-shaped hole.
The grating reading head, is one of optical measurement original paper of position feedback, by mode connects for screw in auxiliary adjustment plate.
The grating scale, is one of optical measurement original paper of bit location feedback, on Z axis motor cabinet.
A kind of advantage of PCB numerical control drilling machines Z axis grating reading head positioner of the utility model is：Process structure is simple,
, adjustment direction low to lathe bed screwed hole status requirement is stable flexibly, adjusting range is big, and position is accurate.

Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1：Whole PCB numerical control drilling machine Z axis grating reading heads adjustment mechanism is arranged on drilling machine lathe bed, grating scale 4
Then it is arranged on motor cabinet；Guide pad 7 is bonded on lathe bed using metal-to-metal adhesive, and the guide groove in homophony whole plate 1 is matched somebody with somebody with guide pad 7
Close positioning of the control homophony whole plate 1 in Y-direction；Guide groove in auxiliary adjustment plate 2 coordinates with the convex in homophony whole plate 1, controls auxiliary
Adjustment plate 2 X to positioning；Grating reading head 3 is installed in auxiliary adjustment plate 2.
As shown in Figures 2 and 3：The present invention is provided with guide groove and a pair of parallel in homophony whole plate 1 and auxiliary adjustment plate 2
Waist-shaped hole, the positioning for grating reading head is adjusted, the guide groove energy auxiliary positioning Y-direction in homophony whole plate 1；In auxiliary adjustment plate 2
Guide groove energy auxiliary positioning X to.
As shown in Figure 2：The limit adjustment width of homophony whole plate 1 is that Y-direction adjusts width 8, and the limit adjustment of auxiliary adjustment plate is wide
Spend for X to adjustment width 9.
Guide groove and guide pad 7 in homophony whole plate 1 are to coordinate, on the guide groove and homophony whole plate in auxiliary adjustment plate 2
Four-prism boss is to coordinate.
Grating reading head 3 is arranged in auxiliary adjustment plate 2, and the countersunk head for installing grating reading head screw is machined with auxiliary adjustment plate 2
The screw thread hole carried is arranged at screw hole, the bottom of grating reading head 3.
