Detailed description of the invention
To the technical scheme in the utility model embodiment be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment comprises:
As shown in Figure 1 to Figure 3, a kind of three ball dynamic positioning mechanisms, comprise moving die plate 1 and fixed form 12, on described fixed form 12, be fixedly installed three spheroids 9, the center of described three spheroids 9 each other line is equilateral triangle, on described moving die plate 1, be fixedly installed a female cone piece 4, one V-shaped groove piece 7 and a plain block 2, a conical bore 13 has caved inward on the outer face of described female cone piece 4, a V-shaped groove 6 has caved inward on the outer face of described V-shaped groove piece 7, the outer face of described plain block 2 is a plane, described female cone piece 4, V-shaped groove piece 7 and plain block 2 respectively with described three spheroids 9 in one of them be oppositely arranged, described female cone piece 4, V-shaped groove piece 7 and plain block 2 and corresponding described spheroid 9 are to contact when contact simultaneously.
Described female cone piece 4 is the toroid contact of described spheroid 9 on described conical bore 13 inwalls with the contact of corresponding described spheroid 9, and the outer peripheral face of spheroid 9 contacts with the contour that the inwall side face of conical bore 13 carries out a week.Described V-shaped groove piece 7 is that described spheroid 9 carries out a contact in the two opposite side walls of described V-shaped groove 6 with the contact of corresponding spheroid 9, described plain block 2 is the some contact of described spheroid 9 on the outer face of described plain block 2 with the contact of corresponding described spheroid 9, and namely the top of spheroid 9 contacts with the point of the outer face of plain block 2.The center line of described V-shaped groove 6 is through the center line of the openend end face 16 of described conical bore 13 and divide the described openend end face 16 of described conical bore 13 equally.
Contact with the single-point of plain block 2 by spheroid 9 and can prevent processing or the swing of measurement mechanism, the i.e. contact point 15 as shown in Figure 3 in this single-point contact position; Can prevent the rotation of processing or measurement mechanism by two contact points 15 in the two opposite side walls of spheroid 9 and V-shaped groove 6, and spheroid 9 moves in the interior self adaptation that can have small quantity of V-shaped groove 6, can avoid excessive location; Can prevent floating of processing or measurement mechanism by spheroid 9 and the annular contact line 14 of conical bore 13 inwalls.Make after premises contact and line contact when moving die plate 1 moves down like this, moving die plate 1 is fixing, no longer motion.Now moving die plate 1 is just fixed with the relative position of fixed form 12, and when later moving die plate 1 moves up and down again, its position also can not change.Moving die plate 1 remains accurately with the relative position of fixed form 12, and the relative position of the part 10 of the to be processed or measurement on the processing on moving die plate 1 or measurement mechanism and fixed form 12 also remains constant.
Preferably, on described fixed form 12, be fixedly installed holder 8, described spheroid 9 is fixedly installed on described holder 8, can make fixing more steady of spheroid 9, and stress-bearing capability is stronger.
Preferably, described plain block 2 is bulk or column.
Preferably, described female cone piece 4 is bulk or column.
Preferably, on described moving die plate 1, be provided with the drive rod 3 that drives described moving die plate 1 to move.Move up and down by the pneumatic or electronic drive rod 3 that makes, so drive moving die plate 1 move up and down, make near or away from spheroid 9.
Preferably, on described moving die plate 1, be provided with measuring stick 5, the axis of described measuring stick 5 is parallel or coaxial with the axis of the measured object of placing on described fixed form 12.
To measure the blind hole 11 of part 10 as example, part 10 is fixed on fixed form 12, the central axis of blind hole 11 and the central axis of measuring stick 5 are overlapped as far as possible.Drive rod 3 drives moving die plate 1 to move down female cone piece 4, V-shaped groove piece 7 and plain block 2 are contacted with corresponding spheroid 9 simultaneously, and now moving die plate 1 is slack, and measuring stick 5 stretches into and in blind hole 11, carries out depth survey.Moving die plate 1 moves down at every turn and all can drop on original position.
In addition, the diameter of measuring stick 5 is much smaller than the diameter of blind hole 11.Measuring stick 5 tests are stretched into blind hole 11 when interior, and by calculating and air pressure and sensor control, test distance that can control survey bar 5, makes the end of measuring stick 5 and the bottom of blind hole 11 keep a minimum safety clearance, and measuring stick 5 can not be broken.
Preferably, described measuring stick 5 and measured object all drop within the scope of the equilateral triangle of center formation of described three spheroids 9.Measuring stick 5 and measured object depart from the outer error that can increase location of equilateral triangle, and error far away is larger outward to depart from equilateral triangle, and it is the most accurate when measuring stick 5 and measured object are positioned at the center of equilateral triangle, to measure.
Spheroid 9 adopts high-abrasive material, and strong shock resistance is non-friable, to ensure its service life.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
