Abstract
Erro-autocompensating index plate with steel balls is made up of two equally distributed steel ball dishes.It is changeless in the steel ball group of each dish the position of a steel ball and dish being arranged.Other steel ball then connects with adhesive and dish and is evenly distributed on the circumference.In 2 whens engagement dish, had the steel ball of site error to produce minor shifts because of outer force unbalance when applying the parallel axial force of depressing.Thereby produce the effect of error auto compensatng.Thereby can reach very high circumference indexing accuracy.That this index dial has is simple in structure, the manufacturing cycle short, low cost and other advantages.Thereby can obtain very high economic benefit.Therefore it has very big promotional value.
Description
The invention belongs to branch garden calibration devices such as mechanical type arbitrary integer.
The present invention is a kind of Erro-autocompensating index plate with steel balls, and the patent close with the present invention is the solid matter steel ball graduator.As United States Patent (USP): US3088340, US3091133, US3177740 and Japan's special permission communique: clear 56-49695, clear 58-27057 etc.They all belong to rigidity solid matter steel ball graduator.Their indexing accuracy depends primarily on the accuracy of manufacture.Foozle directly influences indexing accuracy.The solid matter steel ball graduator requires the diameter of garden post locating surface should satisfy the requirement of steel ball solid matter in the mill.Need grinding repeatedly and test just can reach given size, difficulty of processing is big, and grinding and test are longer man-hour, so the cost height.
Index dial of the present invention can accomplish to reach with simple structure the purpose of high-precision angle five equilibrium.
Index dial structure of the present invention as shown in Figure 1.It is made up of a fixing lower wall (3) and the rotating dish (1) of going up.The steel ball of each dish (2) number equals required five equilibrium number (any limited integer) or its integral multiple.Select for use the steel ball (2) of suitable diameter to cooperate the diameter of dish.Every group of steel ball will be evenly distributed on the garden of dish separately on week.Steel ball (2) and dish combine the employing adhesive between (1) (3).It allows each steel ball can produce small skew under unbalanced external force effect.Thereby produce the effect of error auto compensatng.
The contact point that a steel ball and dish are separately all arranged in the steel ball group of each dish is more than 2.Promptly increase to 4 contact points.Purpose is to guarantee that this steel ball always immobilizes with the relative position that coils under any condition.One of scheme that keeps four contact points can be referring to accompanying drawing 3.Prevent that by two spacer pins (5) with inclined-plane steel ball from doing the skew of garden Zhou Fangxiang.Adjustment screw (4) is used for regulating and the fixing axial location of spacer pin (5).
Upper and lower dish turns over when meshing again behind the certain angle relatively should apply certain parallel axial force of depressing, and forces steel ball (2) skew of site error.Till all steel balls (2) all come in contact.
Look size and the accuracy of manufacture (flatness and garden post degree) and steel ball number and itself the geometric accuracy (garden degree) and the dimensional accuracy (diameter between each steel ball is poor) of upper and lower dish steel ball locating surface (planar annular and cylinder).This index dial can meet or exceed the precision of existing machinery formula index dial or dividing head; Generally can reach the several angle of the error precision of second.Note to improve under the situation of the accuracy of manufacture, even can reach error and be no more than 1 angle second.
The present invention compared with prior art has following advantage: steel ball locating surface of the present invention is only required certain geometric accuracy (garden post degree, flatness) and is not required dimensional accuracy.So time and labour saving when making.General midget plant all can make.Upper and lower dish (1), (3) can be improved the hardness of locating surface without heat treatment after taking suitable technological measure, thus make upper and lower dish (1), (3) if the time can carry out precision turning without grinding machine.
The present invention makes simply, and technological requirement is not high, but owing to have the characteristic of error auto compensatng, can reach very high garden week halving precision with simple device; Particularly normal the requirement adopted the prime number tooth in Gear Processing, and this index dial is good especially for branch adaptability such as any prime numbers.
The present invention has simple in structure than prior art, the manufacturing cycle is short, cost is low, advantage of high precision.Thereby can obtain very high economic benefit, so it has very big promotional value.
Claims (3)
1, Erro-autocompensating index plate with steel balls is by last dish (1), and lower wall (3) and steel ball group (2) are formed.It is characterized in that as shown in Figure 1 rotating dish (1) and the fixing lower wall (3) gone up.The number of the steel ball group in the upper and lower dish equals required five equilibrium number (any limited integer) or its integral multiple, and selects for use appropriate diameter to cooperate the diameter of dish.Steel ball group (2) is distributed on the garden of upper and lower dish (1), (3) on week, keeps interval suitable and that equate between the steel ball.
2, as claim item 1 described Erro-autocompensating index plate with steel balls, the steel ball locating surface that it is characterized in that upper and lower dish (1) (3) is planar annular and cylinder.Adhesive is adopted in combination between steel ball and the dish, and it allows each steel ball can produce small skew under unbalanced external force effect.Thereby produce the effect of error auto compensatng.Above dish (1) and should apply certain parallel axial force of depressing when meshing again after lower wall (3) turns over certain angle relatively, force the steel ball of site error to be offset till all steel balls all come in contact.
3, Erro-autocompensating index plate with steel balls as claimed in claim 1.It is characterized in that respectively having in the steel ball group of upper and lower dish (1) (3) steel ball (2) and separately dish that four contact points are arranged.This is in order to prevent that this steel ball from producing any skew.It guarantees that the variation of relative position does not take place for this steel ball and dish separately.One of structure as shown in Figure 3 preferably.Two spacer pins (5) with inclined-plane are regulated by two adjustment screw (4) and the fixing axial location of spacer pin (5).
