Detailed description of the invention
The present invention is described in detail with detailed description of the invention below in conjunction with the accompanying drawings.
With reference to Fig. 1, it is that the present invention utilizes the method for radial drilling machine grinding shaft like members centre bore to be processed Workpiece spindle 1, at the center, two ends of workpiece spindle 1, is respectively arranged with workpiece spindle centre bore 2, is workpiece spindle 1 Technological datum in the course of processing, in the course of processing of workpiece spindle 1, workpiece spindle centre bore 2 to be utilized enters Luggage presss from both sides, and realizes the polishing to workpiece spindle centre bore 2.
With reference to Fig. 2, the present invention utilizes the device of radial drilling machine grinding shaft like members centre bore to be, including fixing Under on the base 3 of radial drilling machine top 4 and support 5, it is arranged on the main shaft 6 of radial drilling machine Grind top 7, and the centering axle 18 of an auxiliary.
With reference to Fig. 3, Fig. 4 and Fig. 5, support 5 structure in apparatus of the present invention is, including with center The upper plate 8 (the present embodiment is square opening) of opening, with the lower plate 9 of central opening, (the present embodiment is demifacet Round mouth), upper plate 8 and lower plate 9 welded by many isometric steel pipes 10 (the present embodiment is 5) and Becoming, lower plate 9 lower surface is fixedly installed multiple supporting leg 11 (the present embodiment is 5);Table on upper plate 8 Face is symmetrically arranged with at three activity steel plate 13 at fixation steel plate 12 and along central opening surrounding, solid at three Determine steel plate 12 and be all fixedly welded on upper plate 8 upper surface, movable steel plate 13 by two step pins 14 across Being connected on upper plate 8 opening both sides, each fixation steel plate 12 and the movable centripetal position of steel plate 13 all have spiral shell Hole is also separately installed with one group and holds out against screw 15.
The central opening of upper plate 8 and lower plate 9 is to load workpiece spindle for convenience, in order to pull down and the side of installation Just, step pin 14 and its installing hole should use bigger matched in clearance.
With reference to Fig. 6, under top 4 be socketed to form by top body 16 and dead head 17, top body 16 and top The assembling of point seat 17 uses interference fits, and top body 16 uses the materials such as T8 to manufacture, and quenching hardness should More than HRC55, to increase wearability, dead head 17 is manufactured with common steel plate.
With reference to Fig. 7, in order to coordinate above-mentioned apparatus of the present invention, also make and have a prefabricated component to be referred to as centering Axle 18, centering axle 18 and the diameter of workpiece spindle 1 to be processed, length and the size of two ends centre bore Close, in order to ensure precision during centering, centering axle 18 should strictly control the circle of its cylindrical when making Post degree, the datum hole at centering axle 18 two ends should have higher axiality with cylindrical centering axle, to be not more than / 3rd of workpiece precision prescribed are advisable.
Grind top 7 and use the finished product on current tool markets, note its taper shank specification should with used Spindle hole specification on the main shaft 6 of radial drilling machine is good fit.
The present invention utilizes the method for radial drilling machine grinding shaft like members centre bore, utilizes above-mentioned device (lower top Point 4, support 5, a centering axle 18 and grinding top 7), implement according to following steps:
Step 1, according to Fig. 8, by under top 4 and support 5 utilize the T on the base 3 of radial drilling machine Shape groove is fixed on radial drilling machine base 3, is arranged on grinding top 7 on the main shaft 6 of radial drilling machine, Take away the movable steel plate 13 on support 5, centering axle 18 is loaded among support 5, then be reinstalled living Dynamic steel plate 13 is also fixed with step pin 14, and the datum hole of centering axle 18 lower end is mounted on down top 4 On, adjusting four and hold out against screw 13, fixing centering axle 18 after making centering axle 18 the most vertically, to moving down Motion rocker arm drill press spindle 6, makes grinding top 7 enter the datum hole of centering axle 18 upper end, operates radial drill The set lever 19 of bed, fixes headstock, and at this moment the position of main shaft 6 is also fixed, main shaft 6 Can only move up and down and rotation process;
Dial gauge is inhaled on main shaft 6, moves up and down main shaft 6, centering axle 18 cylindrical 90 degree each other Two buses on centering bus moves up and down with main shaft 6 respectively the depth of parallelism, if the depth of parallelism is overproof, Hold out against screw 13 adjust the direction of centering axle 18 by readjusting four, repeat above-mentioned centering process, Until the depth of parallelism reaches precision set in advance, centering well after just reached on main shaft 6 install grinding top Point 7 with under top 4 coaxial purposes, this centering process process with a collection of workpiece time have only to carry out Once;
Centering is the locking state of headstock to be kept after completing, four are held out against screw 13 simultaneously to Unclamp direction and twist 6-10mm, take away movable steel plate 13 and centering axle 18 is taken out.
Step 2, according to Fig. 9, it would be desirable to the workpiece spindle 1 of grinding loads support 5, loads onto movable steel plate 13, the centre bore of workpiece spindle 1 lower end is mounted on down on top 4, now holds out against screw 13 due to four Being in the state unclamped, workpiece spindle 1 can be swung to certain direction and be in the most vertical state by nature.
Four hold out against screw 13 and do not tighten, even if reason is with batch workpiece when this procedure, outward Circle also has allowance, so outside diameter has relatively large deviation, if top tight workpiece axle cylindrical, Each workpiece will adjust, fixed not against workpiece spindle cylindrical when the core of the present invention is exactly grinding center hole Position, but in advance the good main shaft of centering with under top concentric, lock main spindle's, by step 3 institute The grinding top 7 stated automatically is corrected when grinding and is made workpiece spindle 1 be in vertical state.
Step 3, according to Figure 10, manual operation move down main shaft 6 makes grinding top 7 enter workpiece spindles The centre bore of 1 upper end, owing to main spindle box is in the state of position locking, can be automatically so grinding top 7 Correction makes workpiece spindle 1 be in vertical state, at this moment starts main shaft 6 and rotates, and main shaft 6 drives grinding top 7 start the centre bore on vertical state attrition process workpiece spindle 1 top of workpiece spindle 1;
After grinding the centre bore on finished piece(s) axle 1 top, workpiece spindle 1 is turned over individual, re-grind other end center Hole, the attrition process process of a workpiece spindle 1;
By that analogy, then change another workpiece spindle 1 and repeat said process.
