Description
The utility model Gauge for the centre of a circle relates to a kind of specific purpose tool of centering, ruling of being used on round piece, be by left and right two slide rules specifically, left and right two slide rule seats, a central slider, the Gauge for the centre of a circle that two tightening slide blocks of front and back ends are formed.
As everyone knows, on round piece, center, rule, still do not have specific purpose tool at present, can only use instruments such as the Cross ruler that centers that " pincers worker is put into practice " (Science and Technology of Shanghai publishing house, version in 1978) introduce, how much V shape irons, centre gauge, add-leg calipers.Use above-mentioned instrument to center, rule, run into when hole workpiece is arranged, need earlier filler to be carried out in the hole.Filler is one time-consuming operation.When using add-leg calipers to center, also there is the problem of low precision.
The purpose of the utility model Gauge for the centre of a circle will overcome the deficiency of above-mentioned instrument exactly, provides a kind of the need can obtain the center immediately on round piece to there being hole workpiece to carry out filler, and the specific purpose tool that can rule.
The utility model Gauge for the centre of a circle designs according to the principle that the perpendicular bisector of justifying any two strings intersects at the center of circle, by left and right two slide rules, and left and right two slide rule seats, a central slider, two tightening slide blocks of front and back ends are formed.Central slider and tightening slide block are contained on the left slide rule.Left and right two slide rule seats can be launched into 180 ° with the assembling of hinge connecting mode, and respectively there is a pin pin two slide rule seat ends and middle connection place.The pin pin is used to make the slide rule seat to push against at workpiece, plays definite chord length.Slide rule cross section, a left side is
Shape, right slide rule cross section is
Shape.Slide rule seat lower left, a left side has one
The shape chute, there is a screw chute top, uses for tightening fixed short screw.Right slide rule seat below has one
Shape chute, chute medial surface are on the perpendicular bisector of the right side, middle bipod pin line, and there is a screw chute top, use for tightening fixed short screw.The central slider that is installed on the left slide rule has two kinds of structures, and a kind of is to be used to the central slider that centers, rule, by a cuboid and one
The shape bluff body is linked to be stepped, and bluff body upper surface and right slide rule bottom surface can be overlapped, has one in the middle of the cuboid
The shape chute hole, there is a screw chute hole top, uses for tightening fixed short screw.The bluff body upper surface has one towards point, and its position is on the perpendicular bisector of a left slide rule seat left side, middle bipod pin line.Another kind be used to center, the central slider of circumference in equal parts, the sector that has 90 ° of scales by a cuboid and is linked to be stepped, sector upper surface and right slide rule bottom surface can be overlapped, have one in the middle of the cuboid
The shape chute hole, there is a screw chute hole top, uses for tightening fixed short screw.The sector upper surface has one towards point, and its position and is the central point of covering of the fan on the perpendicular bisector of a left slide rule seat left side, middle bipod pin line.The effect of central slider is to cooperate center or center and the circumference in equal parts of determining workpiece with slide rule.Front and back ends tightening slide block is by a cuboid and one
The shape bluff body is linked to be stepped, and the bluff body of front and back ends tightening slide block is respectively at the not ipsilateral of cuboid.Have one in the middle of the cuboid
The shape chute hole, there is a screw chute hole top, uses for tightening fixed short screw.One screw is arranged in the middle of the bluff body, use for tightening the fixed length screw, the tightening long screw is used to push against the workpiece inner periphery.The effect of tightening slide block is that Gauge for the centre of a circle is fixed on the workpiece.
The structure of the utility model Gauge for the centre of a circle but is not limited by the present embodiment accompanying drawing shown in the embodiment accompanying drawing.

Description of drawings
1, left slide rule 2, right slide rule 3, left slide rule seat 4, right slide rule seat 5, central slider 6, front end tightening slide block 7, rear end tightening slide block 8, the short screw 9 of tightening, tightening long screw 10, pin pin
Below in conjunction with accompanying drawing the utility model Gauge for the centre of a circle is described further.
Be that benchmark is when having hole workpiece or scarce annulus class center surely with the cylindrical, earlier left slide rule (1) and right slide rule (2) are inserted left slide rule seat (3) and right slide rule seat (4) respectively, again rear end tightening slide block (7) and the central slider (5) that centers, rule are contained on the left slide rule (1), place it on the workpiece end face then.Three pin pins (10) of left and right slide rule seat (3), (4) are close to above the excircle, the projection line of at this moment right slide rule (2) medial surface with right, in the perpendicular bisector of two pin pins (10) line overlaps, and the movement locus of the central slider that centers, rules (5) upper punch point with in, the perpendicular bisector of the line of left two pin pins (10) overlaps.Tighten the short screw (8) of left slide rule (1) top tightening, rear end tightening slide block (7) is against on the inner peripheral surface, tighten short screw (8) of tightening and tightening long screw (9).Slide right slide rule (2) and central slider (5) make the medial surface line pressure of right slide rule (2) live dashing a little on the central slider (5), tighten the short screw (8) of tightening of central slider (5), remove right slide rule (2), can obtain the central point of this round piece.Then can descend step line work.
When with the inner periphery being the fixed porose workpiece centre of benchmark, the method that Gauge for the centre of a circle is fixed on the workpiece is that front end tightening slide block (6) is against hole circle on week, tighten short screw (8) of tightening and tightening long screw (9), three pin pins (10) of slide rule seat are placed in the hole, abut against on the circumference, all the other as previously mentioned.
When drawing the circumference bisector, a central slider that need will center, rule changes into and centers, the central slider of circumference in equal parts gets final product.After obtaining the circular hole central point, prolong two graduation marks of the required number of degrees, meet at, obtain two intersection points by the Equal round contour.
Be that benchmark is when deciding the atresia workpiece centre with the cylindrical, right slide rule (2) is inserted in right slide rule seat (4) chute, look the used length of slide rule and tighten the short screw (8) of tightening, on left and right two pin pins (10) push against on the workpiece circumference, along the inboard standardized straight line of slide rule, change the standardized again straight line of a direction, two straight line joinings promptly are the centers of this round piece.Next step just can carry out line work.
The utility model Gauge for the centre of a circle can be made the series of products of different size size, selects the Gauge for the centre of a circle of different size for use according to the workpiece size.
The utility model Gauge for the centre of a circle is a kind of specific purpose tool easy to use, do not need there being hole workpiece to carry out filler, and saving of work and time, the accuracy height is given the line pincers worker and repairs pincers worker to bring great convenience.
