Abstract
The invention discloses a hole location calibration device. The hole location calibration device comprises a jig hole detection rod, a master part hole detection rod, a connecting screw rod and lock nuts, wherein the master part hole detection rod is sleeved on the front end of the connecting screw rod and the jig hole detection rod is sleeved on the back end of the connecting screw rod. The invention is characterized in that the structure is simple and the positioning accuracy of the multi-hole jig can be conveniently and fast adjusted; and the calibration device can be widely used in the mechanical manufacture field.
Description
Technical field
The present invention relates to a kind of new hole location calibration device, particularly at the device that is used for calibrating hole site on porous drill jig and the master body on the special purpose machine tool.
Background technology
At present, on special purpose machine tool, guarantee that the hole is that positional precision is higher on the part that the porous drill jig processes; On must the calibration drill jig on the master body of hole and part to be processed the position in hole until coaxial; But when calibrating with the test bar that the sort of precision reaches the 0.01mm axiality, the problem of existence is: when the disalignment of the hole of porous drill jig and master body, the axiality test bar can't insert; The position deviation in hole can't record on hole relative standard's exemplar on the drill jig, can't adjust drill jig; Deviation to the hole of those drill jigs and master body can only onlinely detect in addition, receives a lot of restrictions of equipment, measures very inconvenience.
Summary of the invention
To the deficiency of prior art, the present invention provides a kind of hole location calibration device, this device solves the high axiality test bar of precision can't insert the problem of seized gaging hole.
Hole location calibration device of the present invention comprises drill jig hole test bar, master body hole test bar and connecting screw rod and locking nut, and master body hole test bar is sleeved on the front end of connecting screw rod, and drill jig hole test bar is sleeved on the rear end of connecting screw rod.
In the hole location calibration device of the present invention; The front and back two sections (master body test bar and drill jig hole test bars) of high accuracy axiality test bar are split up into independent structures; Even make drill jig and master body hole disalignment; Can realize that also the drill jig test bar can insert the drill jig hole, the master body test bar can insert the master body hole.Has suitable gap between at least one of drill jig hole test bar and master body hole test bar and the connecting rod; Gap value is generally 0.1～5mm, and the cooperating of drill jig hole test bar and drill jig hole, master body hole test bar cooperated by H7/h6 with cooperating all of master body hole.
In the hole location calibration device of the present invention, test bar external diameter overgauge exemplar hole, drill jig hole test bar external diameter, the rear portion of test bar is provided with horizontal tag plane in the drill jig hole.
In the hole location calibration device of the present invention, the master body test bar can be measured the position deviation situation of any direction for carrying out 360 degree rotational structures around connecting screw rod.Under connecting screw rod locking nut locking state; Master body test bar and drill jig hole test bar are fixing overall structure; Promptly through locking connecting screw rod locking nut; Make separately two sections become an integral body again, and this integral body truly reflect and has fixed the position deviation situation in drill jig hole and master body hole.
In the hole location calibration device of the present invention; To be carried on the degree test bar device of position in the position deviation information in drill jig hole of being inconvenient on the lathe measure and master body hole; Position degree test bar device is transferred on the v block on the platform with convenient this two sections position deviations on the horizontal vertical both direction of measuring easily of height gauge; Realized the conversion of the difficult ＂ of ＂, the conversion of measuring the place, the conversion of measuring object to the easy ＂ of ＂.
Can find out that through above-mentioned explanation hole location calibration device of the present invention has simple in structure, the information of the information translation that should not measure for being prone to measure, easy to use flexible, applied widely.

The specific embodiment
Structure and method for using below in conjunction with description of drawings hole location calibration device of the present invention.
One. unclamp locking nut 1 earlier; With the hole on the master body test bar 3 insertion master bodies 6; With the hole on the drill jig hole test bar 2 insertion drill jigs 5; Ajust drill jig test bar 2 and lean on the horizontal tag plane 9 of locking nut end to be horizontal direction, the nut 1 tension connecting screw rod 4 of screwing makes the end face of master body test bar 3 be close to the end face of drill jig hole test bar 2, and (like Fig. 1) extracts whole detection device then.
Two. on detection platform, measure the deviation of horizontal/vertical both direction master body test bar to drill jig hole test bar with V-type calibrated bolck 7 and height gauge 8.Put horizontal tag plane that drill jig test bar 2 leans on the locking nut end earlier in horizontal direction; Measure data of exemplar test bar 3 surperficial peaks with height gauge; Be rotated in brill on the v block then and touch test bar 180 degree and record another data, poor/2 of these two data are exactly the position deviation of horizontal direction; Lean on the horizontal tag plane of locking nut end to place vertical direction drill jig test bar 2; Also record data of master body test bar 3 surperficial peaks; Being rotated in brill on the v block then touches test bar 180 degree and records another data; Poor/2 of these two data are exactly the position deviation of vertical direction, so just know the position deviation of drill jig relative standard exemplar at the horizontal vertical both direction.
Adjust the installation site precision of drill jig on lathe again according to this position deviation, can insert drill jig and master body corresponding aperture until the axiality test bar of precision such as 0.01mm.
Use hole site of the present invention checkout gear precondition to be: the master body hole makes things convenient for position degree adjusting device pulling out from the hole on the drill jig 5 after the locking less than the drill jig hole.If greater than the drill jig hole, also can in the master body hole, add an auxiliary concentric locking collar and change it into situation use less than the drill bushing hole.
What should explain is: above embodiment is only unrestricted in order to explanation the present invention, and the present invention also is not limited in above-mentioned giving an example, and all do not break away from the technical scheme and the improvement thereof of the spirit and scope of the present invention, and it all should be encompassed in the claim scope of the present invention.
