Abstract
The invention discloses a null-setting device of a double-ended grinding machine. The double-ended grinding machine comprises left and right grinding heads and a machine body; the null-setting devices are mounted at the two sides of the left and right grinding heads, respectively; each null-setting device is assembled on a grinding head base by use of a measuring rod; measuring blocks are assembled and fixed with the machine body; adjusting nuts are screwed down on the measuring blocks, respectively; locking blocks are inserted in the inner holes of the adjusting nuts and fastened by using locking screws; a dial indicator inserted in the locking block by an insertion depth so that a contact on the dial indicator is capable of touching the surface of the measuring rod. At least two adjusting nuts are provided, and the locking blocks as many as the adjusting nuts and correspondingly inserted and mounted. The null-setting devices are utilized upon loss of parallel precision of the end faces of left and right main shafts of the machine, vertical precision to a dresser, and the like, so that the precision can be recovered quickly; the null-setting device is convenient, fast, accurate, and the like.
Description
Technical field:
The present invention relates to a kind of null-setting device, be specially adapted to use on double-ended grinding machine.
Background technology:
Double-ended grinding machine is applicable to high accuracy, the large batch of processing such as roller, lasso, auto parts and components, hydraulic pressure valve block class, in double-ended grinding machine process, in order to obtain higher grinding accuracy, must be able to allow the workpiece can rotation in grinding area.
Reach above-mentioned requirements, solution must be adjusted left and right bistrique a minute angle in horizontal plane and vertical plane.The method of existing adjustment bistrique angle (horizontal angle, vertical angle): emery wheel is pulled down together with grinding wheel flange, at right grinding wheel spindle, load onto dial gauge, make contact touch left main shaft end face, rotating spindle, if be as the criterion with operator, dial gauge reading upper and lower is to the poor perpendicularity, the poor horizontal angle that represents of front and rear direction of representing.In addition because Double End bistrique debugging is careless or the reason such as transportation, easily cause the left and right main shaft end face of lathe parallel and with the loss of the precision such as trimmer is vertical.
The method of existing recovery machine tool grinding head positional precision: the finishing arm of dismantling, on trimmer main shaft, install and measure plate, on grinding wheel spindle, load onto respectively dial gauge, contact touches measurement plate, and rotating spindle is read dial gauge numerical value, move left and right bistrique, make it reach required precision.
While measuring due to said method, preparation is more, tear emery wheel, finishing arm etc. open, wastes time and energy.
Summary of the invention:
Task of the present invention be propose a kind of easy to adjust, quick, can adjust accurately the angle of bistrique and the left and right main shaft end face of recovery lathe is parallel and with a kind of double-ended grinding machine null-setting device of the precision such as trimmer is vertical.
Task of the present invention completes like this, a kind of double-ended grinding machine null-setting device, it comprises left and right bistrique, lathe bed, it is characterized in that: null-setting device is equipped with respectively in described bistrique both sides, left and right, described null-setting device is to be put together on bistrique base by measuring stick, measuring piece and lathe bed is mounted with, on described measurement piece, be screwed with respectively adjusting nut, fastening with lock-screw in the endoporus of latch segment insertion adjusting nut, dial gauge inserts in latch segment, and insertion depth is that the surface that can contact measuring stick with the contact on dial gauge is as the criterion.Described adjusting nut is more than at least two, and latch segment is to install with the corresponding insertion of quantity of adjusting nut.The adjustment of left and right bistrique precision is to rely on the reading on the dial gauge inserting in latch segment to be unanimously as the criterion, and latch segment exits from locking nut locks afterwards with alignment pin.
The present invention has following effect: the present invention is parallel and use this device can recover fast precision with trimmer is vertical etc. when precision loses at the left and right main shaft end face of lathe, has the advantages such as convenient and swift, accurate.
Accompanying drawing explanation:
Fig. 1 is the double-ended grinding machine surface structure schematic diagram of invention; Fig. 2 is null-setting device structural representation.
Drawing explanation: 1, emery wheel, 2, grinding wheel spindle, 3, bistrique base, 4, null-setting device, 5, lathe bed, 6, dial gauge, 7, latch segment, 8, lock-screw, 9, measure piece, 10, adjusting nut, 11, alignment pin, 12, measuring stick.
The specific embodiment:
The technical program is carried out in debug process at lathe, left, the adjustment of right corner degree does not need to dismantle emery wheel, finishing arm etc., do not need to install special tooling yet, only need to be when moving bistrique base, rely on dial gauge just can read concrete numerical value, realize accurately and measuring, and left at lathe, right main shaft end face is parallel and can use this to install fast quick-recovery precision with trimmer is vertical etc. when precision loses, as shown in Figure 1, left, right bistrique is separately fixed on bistrique base, base and lathe bed 5 assemblings, left, grinding wheel spindle 2 is housed respectively on right bistrique, emery wheel 1 is housed on main shaft 2, a described left side, null-setting device 4 is equipped with respectively in right bistrique both sides, as shown in Figure 2, described null-setting device is by dial gauge 6, latch segment 7, lock-screw 8, measure piece 9, adjusting nut 10, alignment pin 11, measuring stick 12 forms, described measuring stick 12 puts together on bistrique base 3, measuring piece 9 is mounted with lathe bed 5, on described measurement piece 9, be screwed with respectively adjusting nut 10, described latch segment 7 inserts respectively in the endoporus of three adjusting nuts fastening with lock-screw, dial gauge 6 inserts in latch segment, insertion depth contacts measuring stick square face with the contact on dial gauge and is as the criterion, at this moment rotate adjusting nut 10, make a left side, the reading of the dial gauge of right bistrique both sides is in full accord, take off latch segment and dial gauge, alignment pin location is installed on adjusting nut, its precision can not changed, the endoporus of described adjusting nut 10 plays positioning action with measurement piece, can guarantee that rigging error is less than 0.01mm.
In lathe debug process, in the adjusting nut 10 of measuring piece 9 upper ends, insert latch segment 7 and dial gauge 6 combinations, with lock-screw 8, lock, in any one adjusting nut 10 of measuring piece side, insert other a set of latch segment and dial gauge 6 combinations simultaneously, and lock with lock-screw 8, at this moment move bistrique angle, bistrique base 3 can be done upper and lower left and right adjustment together with measuring stick 12, the reading of dial gauge 6 also changes simultaneously, can observe according to the numerical value of two dial gauges 6 variation of bistrique angle.
When the precision such as parallel and trimmer is vertical at the left and right main shaft end face of lathe are lost, three adjusting nuts 10 on the measurement piece 9 that can install by left and right bistrique both sides, latch segment is inserted respectively in the endoporus of adjusting nut, dial gauge inserts latch segment, read the numerical value of dial gauge 6, move bistrique base 3, when dial gauge 6 numerical value of three positions are when in full accord, the precision that lathe is lost is recovered the precision of dispatching from the factory completely.The angle with convenient, fast adjustment bistrique, can give again the precision that lathe is lost fast for change.
