Abstract
The utility model discloses a kind of wheel dresser of double disc surface grinding machines with vertical spindle, the semi-circular arms of disc type conditioning arm is provided with paired finishing block, in breach in the middle of often pair of finishing block, latch segment is housed, described disc type conditioning arm is fixed on main shaft, lower grinding head grinding wheel is contained on the lower main axis of lathe, upper grinding head grinding wheel is contained on the upper main shaft of lathe, the taper roll bearing spacer being contained in described main shaft two ends is separately and with locking nut locking, and described taper roll bearing is compressed by bearing holder (housing, cover) and upper end cover and bottom end cover.This structural rigidity is good, stable movement, and dressing efficiency is high, plane of grinding wheel even uniform after revising, and is applicable to CBN crushing and high-precision double-ended grinding machine.
Description
Technical field:
The utility model relates to a kind of wheel dresser, uses when being specially adapted to the grinding of double disc surface grinding machines with vertical spindle to upper and lower two planes of workpiece.
Background technology:
Double disc surface grinding machines with vertical spindle is mainly used in the grinding of upper and lower two planes of workpiece, upper and lower two planes of emery wheel High Rotation Speed grinding work piece also reach high-precision requirement, existing is adopt single armed mechanism, swing type carries out grinding to upper and lower two planes of workpiece, its shortcoming is: bumpy motion, and dressing efficiency is not high.
Summary of the invention:
Task of the present utility model proposes good, the stable movement of a kind of structural rigidity, and upper and lower two planes of grinding work piece also reach the wheel dresser of a kind of double disc surface grinding machines with vertical spindle of high-precision requirement.
Task of the present utility model completes like this, a kind of wheel dresser of double disc surface grinding machines with vertical spindle, it is characterized in that: the semi-circular arms of disc type conditioning arm is provided with paired finishing block, in breach in the middle of often pair of finishing block, latch segment is housed, described disc type conditioning arm is fixed on main shaft, lower grinding head grinding wheel is contained on the lower main axis of lathe, upper grinding head grinding wheel is contained on the upper main shaft of lathe, the taper roll bearing spacer being contained in described main shaft two ends separates and locks with locking nut, described taper roll bearing is compressed by bearing holder (housing, cover) and upper end cover and bottom end cover.Notch geometry in the middle of often pair of described finishing block is wide at the top and narrow at the bottom, and the quantity of latch segment at least 5, the quantity at least 5 of finishing block is right.Described sensor block is controlled by electrical equipment inductive head.
The utility model has following effect: this structural rigidity is good, stable movement, and dressing efficiency is high, plane of grinding wheel even uniform after revising, and is applicable to CBN crushing and high-precision double-ended grinding machine.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model; Fig. 2 be Figure 1A to the structural representation of disc type conditioning arm.
Drawing illustrates: 1, lathe bed, 2, latch segment, 3, finishing block, 4, disc type conditioning arm, 5, main shaft, 6, bottom end cover, 7, lower grinding head grinding wheel, 8, upper grinding head grinding wheel, 9, spacer, 10, bearing holder (housing, cover), 11, taper roll bearing, 12, synchronous pulley, 13, sensor block, 14, locking nut, 15, upper end cover, 12-16, synchronous pulley, 17, reducing motor.
Detailed description of the invention:
Embodiment is described in detail in conjunction with above accompanying drawing, the swing arm of the technical program disc type substitutes single armed mechanism, circumference rotates to substitute and swings, as shown in Figure 2, the shape of disc type conditioning arm 4 is semicircular structure, semicircular circumferential wall is provided with paired finishing block 3, leaving certain gaps uncovered by the economic plan between the finishing block of often pair, be filled with latch segment 2 in breach and pass through screw fastening, the shape of latch segment 2 is wide at the top and narrow at the bottom, the quantity of described latch segment 2 can be 5, the quantity of described finishing block 3 is 5 right, above structure is the contact area increasing finishing block and emery wheel while of improving good rigidly, thus reach the effect improving dressing efficiency and improve finishing flatness, described disc type conditioning arm is fixed on main shaft 5, the rotation of axle 5 is repaired and dressing the lower grinding head grinding wheel 7 and upper grinding head grinding wheel 8 that are in trim locations, furtherly: lower grinding head grinding wheel 7 is contained on the lower main axis of lathe, upper grinding head grinding wheel 8 is contained on the upper main shaft of lathe, taper roll bearing 11 spacer 9 being contained in the two ends of described main shaft 5 separates and uses locking nut 14 to lock, described taper roll bearing assembly is contained in bearing holder (housing, cover) 10 together, compresses with upper end cover 15 and bottom end cover 6.Described bearing holder (housing, cover) is fixed on the upper surface of lathe bed 1, also ensure that stability when disc type conditioning arm rotates simultaneously, described main shaft 5 top is fixed with sensor block 13, is controlled the rotating cycle auto-compensation correction amount of feeding of origin position and main shaft by electrical equipment inductive head.The driving of axle 5 is that synchronous pulley by synchronous pulley 12 and reducing motor 17 are connected and 12-16 clamp expansion set and provide motion, during work, upper grinding head grinding wheel 7 and lower grinding head grinding wheel 8 carry out regular microfeed by electrical equipment control, drives disc type conditioning arm 4 to complete crushing by main shaft.
