The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment is illustrated:
The utility model adopts two-way clamping frame (1), and one is connected with the handle of a knife of universal machine tools, one dial gauge (2) and measurement headgear (8) is installed.The manufacturing of two-way clamping frame (1) is simple, and the axiality at principal security two gets final product at 0.015mm.The manufacturing of measuring headgear (8) mainly is to guarantee to cooperate with clamping frame (1) and guarantee that the sphere centre of gage outfit (9) and clamping frame (1) mating surface axiality are in 0.01mm.The manufacturing of gage outfit (9) will guarantee that length gets final product with the proportionate relationship of measuring pearl with the semi circular surface that cooperates of measuring headgear (8).Remaining presses making such as showing to transmit pin (7) simpler.Use engine lathe can finish making.
A kind of concrete structure of the utility model centering determinator is as follows: two-way clamping frame (1) inner chamber is equipped with dial gauge (2), the head (15) that presses of dial gauge (2) presses mutually with the head (16) that presses of pressing table to transmit pin (7), under pressing table transmission pin (7) gage outfit (9) is housed, gage outfit (9) directly presses measured piece, gage outfit (9) can freely swing around the center of radius R A (12), pressure table transmission pin moves up and down, and produces the reading of dial gauge, also reflects according to specific direct ratio.Adopt the two-way clamping frame of oneself making (1), comprise cylinder shank ￠ Q (10) that is connected with the standard handle of a knife and the interior round hole part ￠ P (11) that is connected with the gage outfit cover, wherein cylinder shank ￠ Q (10) adopts the shank size dimension of standard cutter, the interior circular hole ￠ P (11) that is connected with measurement headgear (8) adopts sizeable size to cooperate with measurement headgear (8) part, cylinder shank ￠ Q (10) will guarantee axiality preferably with the interior circular hole ￠ P (11) that measurement headgear (8) is connected, and some will be used to clamp dial gauge (2) or amesdial; Measure of headgear (8) and be connected by circular arc with gage outfit (9), the interior circular hole with two-way clamping frame (1) is connected, and the sphere centre that measurement headgear (8) is connected with gage outfit (9) circular arc will guarantee the axiality of the outside cylinder that is connected with two-way clamping frame (1); The inside epimere of measuring headgear (8) has screw thread, and hypomere is smooth inner headed face.Wherein threaded portion is torqued into countersunk nut, compresses and regulate gauge head back-moving spring (6).Gauge head back-moving spring (6) mainly is to be used for resetting of gage outfit (9), and gauge head back-moving spring (6) makes gage outfit (9) center position that resets back by pressing table to transmit pin (7).Press table to transmit of pin (7) ladder and contact with dial gauge (2), one contacts with gage outfit (9), and the appearance face of cylinder and measurement headgear (8) matched in clearance can arbitrarily be rotated and slide up and down.Gage outfit (9) is that sphere contacts with measuring headgear (8), gage outfit (9) can solderless wrapped connection touch the random rotary oscillation of sphere centre, the swing that sphere centre is touched in gage outfit (9) solderless wrapped connection will produce the single-point contact by the face that contacts with pressure table transmission pin (7), move up and down thereby make the swing of gage outfit change into pressure table transmission pin, pressing table to transmit just sliding up and down of (7) of pin can be reflected at slippage on the reading of dial gauge (2).As Fig. 2, gage outfit is RA: B=1 to what contact pressure table transmission pin apart from B (14) ratio with gage outfit RC with the radius R A that contacts sphere that measures headgear (8): 5.Can reflect meter-pressing amount and press meter reading by direct ratio in such ratio.It is RC (13) that gage outfit (9) is pressed the pendulum amount, and then the reading direct ratio reaction at dial gauge is 0.1RC (13).
